In this study of the recovery and purification of rapamycin from the culture broth of an actinomycetes strain MTCC 5681, we investigated various factors such as biomass separation, suitable solvents for extraction, normal phase and flash chromatographic conditions and selective precipitation to obtain rapamycin in substantially pure form of the product. Adsorption chromatography particularly with normal phase and flash chromatography, in combination with centrifugal decantation is found to be the most suitable for separation as well as purification of rapamycin. Centrifugal decantation technique is likely to emerge as an efficient, industrially scalable, high yielding and economical process for biomass separation. The purity of rapamycin obtained through the method described was 99.4% which has not been reported so far.

- Abstract
The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at euro23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap.The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders.The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

Aerospace Engineering(Formerly Aeronautical Engineering) - Abstract
The goal of this study is the multi-mode structural vibration control in the composite fin-tip of an aircraft. Structural model of the composite fin-tip with surface bonded piezoelectric actuators is developed using the finite element method. The finite element model is updated experimentally to reflect the natural frequencies and mode shapes accurately. A model order reduction technique is employed for reducing the finite element structural matrices before developing the controller. Particle swarm based evolutionary optimization technique is used for optimal placement of piezoelectric patch actuators and accelerometer sensors to suppress vibration. H{infty} based active vibration controllers are designed directly in the discrete domain and implemented using dSpace® (DS-1005) electronic signal processing boards. Significant vibration suppression in the multiple bending modes of interest is experimentally demonstrated for sinusoidal and band limited white noise forcing functions.

Platelets play a major role in normal hemostasis and congenital defects in platelet function are associated with bleeding manifestations that are largely mucocutaneous in origin and markedly variable in severity. They arise by different mechanisms and may be classified as disorders of: (1) platelet-agonist interaction, (2) platelet-vessel wall interaction (vWD and Bernard-Soulier syndrome), (3) platelet-platelet interaction (congenital afibrinogenemia and Glanzmann's thrombasthenia), (4) platelet secretion, and (5) platelet-coagulant protein interaction. Excluding vWD, most congenital platelet dysfunctions currently fall in the category of platelet secretion defects. Some of these patients have storage pool deficiency or defects in thromboxane synthesis, but the majority have normal granule stores. The underlying mechanisms in this large, heterogeneous group of dysfunctions remain to be elucidated. Bleeding episodes of vWD are managed by the administration of DDAVP or cryoprecipitate. The major treatment modality in the management of bleeding episodes and surgical procedures in patients with congenital platelet defects is platelet transfusions. Evidence is becoming available that many of these patients may respond to intravenous infusion of DDAVP with a shortening of the bleeding time. The specific groups of patients who will respond, and the efficacy of DDAVP in clinical situations remains to be established.

The current research looks at the overall state of emerging economies as well as income comparisons. The study employs the 3sls model. Tourism benefits from economic growth as well. Tourism is attracted by economic prosperity, and tourism will increase tourism. According to the findings, economic growth has a negative impact on the environment, and the environment has an adverse effect on economic growth. As income activity accelerates, so will environmental emissions, and environmental emissions have a detrimental impact on economic growth? Further findings imply that tourism has a favorable impact on the environment, with an increase in tourism causing a depreciation of the ecosystem. Environmental pollution has a favorable effect on tourism, as the majority of people travel to other countries for business and religious reasons. This can be found in all models. The exchange rate has a negative influence on the overall and high-income groups, but a favorable effect in the reduced groups. In all models, the other variable, political instability, has a negative effect on tourism, while trade has a favorable effect. GDP is boosted by the literacy rate and gross capital formation Population increase, urbanization, and energy use all have a favorable impact on environmental emissions, according to the study. According to the findings, host nations should not only encourage tourism, but also guarantee that the environment is not harmed, therefore ecofriendly must be pushed to maintain a seamless and sustainable development process.

Environmental problems caused by global warming are becoming alarming with every passing day. To curb greenhouse gas (GhG) emissions, promoting alternative fuel vehicles (AFVs) and sustainable transport mode choices is critical. This study explores the predictors of eco-social purchase, use, and conservation intentions in a developing country by employing an extended model of the theory of planned behaviour (TPB). Using a self-administered survey technique, data were collected from a nationally representative sample of 1372 customers of three leading automobile manufacturers from eight big cities of Pakistan. Partial Least Squares Structural Equation Modelling (PLS-SEM) was applied to test the measurement and structural models. Results showed that the extended model of TPB received support in the context of Pakistani culture and for the targeted behaviours related to eco-social purchase, use, and conservation intentions concerning AFVs. Implications for marketers and theoretical contribution are discussed at the end.

- Abstract
Objective: To determine tissue factor procoagulant activity (TF-PCA) in patients with type 1 diabetes and to examine effects of hyperglycemia and hyperglycemia plus hyperinsulinemia on TF-PCA.Research Design and Methods: We have determined circulating TF-PCA and other coagulation factors under basal (hyperglycemic) conditions, after acute correction of hyperglycemia, in response to 24 h of selective hyperglycemia, and in response to 24 h of hyperglycemia plus hyperinsulinemia in nine type 1 diabetic patients and in seven nondiabetic control subjects.Results: As shown previously in patients with type 2 diabetes, basal TF-PCA and plasma coagulation factor VIIa (FVIIa) were higher in patients with type 1 diabetes than in nondiabetic control subjects. However, in contrast with type 2 diabetes, normalizing glucose did not decrease the elevated TF-PCA levels, and raising glucose or glucose plus insulin levels did not increase TF-PCA.Conclusions: Patients with type 1 diabetes have elevated circulating TF-PCA and FVIIa levels and are in a procoagulant state that may predispose them to acute cardiovascular events. The mechanisms regulating TF-PCA in patients with type 1 and type 2 diabetes are different and should be further explored. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: Oseltamivir resistance among 2009 pandemic influenza A (H1N1) viruses (pH1N1) is rare. We investigated a cluster of oseltamivir-resistant pH1N1 infections in a hospital ward.Methods: We reviewed patient records and infection control measures and interviewed health care personnel (HCP) and visitors. Oseltamivir-resistant pH1N1 infections were found with real-time reverse-transcription polymerase chain reaction and pyrosequencing for the H275Y neuraminidase (NA) mutation. We compared hemagglutinin (HA) sequences from clinical samples from the outbreak with those of other surveillance viruses.Results: During the period 6-11 October 2009, 4 immunocompromised patients within a hematology-oncology ward exhibited symptoms of pH1N1 infection. The likely index patient became febrile 8 days after completing a course of oseltamivir; isolation was instituted 9 days after symptom onset. Three other case patients developed symptoms 1, 3, and 5 days after the index patient. Three case patients were located in adjacent rooms. HA and NA sequences from case patients were identical. Twelve HCP and 6 visitors reported influenza symptoms during the study period. No other pH1N1 isolates from the hospital or from throughout the state carried the H275Y mutation.Conclusions: Geographic proximity, temporal clustering, presence of H275Y mutation, and viral sequence homology confirmed nosocomial transmission of oseltamivir-resistant pH1N1. Diagnostic vigilance and prompt isolation may prevent nosocomial transmission of influenza. [ABSTRACT FROM AUTHOR]- Published

- Abstract
PURPOSE: To determine the relationship between alcohol use disorders (AUDs) and herpes simplex virus type 2 (HSV-2), hepatitis B virus (HBV), and human immunodeficiency virus (HIV) infections among a sample of sexually active adolescents. METHODS: Subjects were 240 sexually active male and female adolescents aged 14 to 21 years (mean 17.5 years) recruited from clinical and community settings in western Pennsylvania between 1991 and 1995; 55% had a lifetime history of AUDs (63 females, 69 males) and 45% did not have a lifetime history of AUDs (57 females, 51 males). Participants provided information about demographic factors and sexual behaviors as well as a serum sample that was assayed for antibodies to HSV-2, HBV, and HIV infections. Multivariate logistic regression was used to determine the independent relationship of AUDs to HSV-2 infections among females. RESULTS: The seroprevalence of HSV-2 infections was 15% among females and 0% among males; the overall prevalence of HBV (1.2%) and HIV (0.4%) infections was very low. Among adolescent females, the seroprevalence of HSV-2 infections was significantly higher among those with an AUD (19%), compared with those without an AUD (10.5%) (adjusted odds ratio 8.1, 95% confidence interval 1.5-44.8, p =.017). CONCLUSIONS: Adolescent women with an AUD appear to be at substantially increased risk of HSV-2 infection. These results highlight the need to address sexually transmitted diseases among adolescents with alcohol problems. [ABSTRACT FROM AUTHOR]

Aerospace Engineering(Formerly Aeronautical Engineering) ,Aerospace Engineering - Abstract
Interference fits are an effective method for improving the fatigue performance of bolted joints. The use of Taperlok bolts in aircraft joints is one such example. One of the most important but difficult problems to analyse in these joints is their behaviour after the onset of separation between pin and plate.Extensive work has been done in the past for the analysis of interference fit joints prior to separation. A comprehensive survey of this area (up to 1965) was brought out by Venkataraman. He also presented many new analytical solutions by a direct method of continuum analysis for interference joints in finite domains. Analysis of these problems in the pre-separation zone continues to draw attention and recently, John Crews used a complex variable technique to analyse the stresses around a flexible pin in an infinite plate under uniaxial tension.

To understand the functional changes induced by storage, we have examined the adenine nucleotides of platelets stored for 72 hr at 22 degrees C and 4 degrees C. Ten platelet concentrates (PC) were stored at each temperature with five in each group having a final volume of 50 ml and 30 ml. The total ATP and ADP content of platelets decreased following storage in all 4 groups of PC, with the decrease being greater in the PC stored at 22 degrees C than those at 4 degrees C. The mean thrombin secretable ATP + ADP content of platelets from PC stored at 22 degrees C and 4 degrees C were 29.7% and 19.7% of the total content, respectively (p less than 0.001). Thus, cold stored platelets have a higher total content of ATP + ADP but secrete distinctly lesser amounts than 22 degrees C stored platelets. Labeling of the metabolic pool adenylates with 14C-adenine revealed a greater decrease in the adenylate energy charge of the platelets stored at 4 degrees C. The secretion defect demonstrated in cold stored platelets may be related to the inability of these platelets to maintain ATP homeostasis.

- Abstract
Platelets stored as concentrates (PC) for 72 h at 22 degrees C develop a functional defect. Alterations in adenine nucleotides of platelets have been shown to affect platelet function. Adenine nucleotide content of platelets was measured before and after storage and a decrease of 27.1 /+- 1.7% (mean /+- SE) in ATP and 39.1 /+- 2.6% in ADP were found in 34 PC stored with final volume of 50 ml. In 11 PC with 30 ml volume. ATP and ADP decreased by 39.4 /+- 3.2% and 49.4 /+- 2.1%, respectively. The mean ATP to ADP ratio of stored platelets was significantly higher than of fresh platelets in both groups, suggesting a relatively greater decrease in granular than metabolic pool nucleotides. Levels of low affinity platelet factor 4 measured by radioimmunoassay in plasma from 0.86 /+- 0.08 microgram/ml in the fresh PC to 8.59 /+- 0.39 microgram/ml in stored PC, indicating a concomitant alpha-granular secretion. Labeling of metabolic pool with 14C-adenine revealed a mean decrease in the adenylate energy charge of 2.0 /+- 0.4% in 12 of 16 stored PC, with a lower ATP and higher hypoxanthine labeling in stored as compared to fresh platelets. These observations suggest that stored platelets develop an acquired defect in both dense and alpha granules and in their ability to maintain ATP homeostasis.

20. Effect of heparin on the in vivo release and clearance of human platelet factor 4

Rao, AK, Niewiarowski, S, James, P, Holt, JC, Harris, M, Elfenbein, B, and Bastl, C
- Abstract
Intravenous injection of heparin (100 U/kg) into normal volunteers resulted in an increase of platelet factor 4 (PF4) level in platelet- poor plasma from a mean value of 18.1 +/- 6.6 ng/ml before the injection to 257.9 +/- 68.3 ng/ml at 5 min after injection. PF4 antigen isolated from “postheparin plasma” by adsorption on heparin-agarose and elution with 2.0 M NaCl and “authentic PF4” isolated from human platelets showed identical patterns of migration as determined by sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Material released by washed human platelets was injected intravenously into rats. The clearance of PF4 followed a biphasic exponential pattern. The half-lives (T1/2) for the fast and slow components for control rats were 1.2 and 17.1 min. Heparin significantly extended the half-life of human PF4 in rat circulation. The clearance of PF4 injected together with heparin followed a single component model with a half-life of 27.6 min. Administration of heparin to rats that had been previously injected with human platelet releasate resulted in a 30-fold increase of plasma PF4 level in their circulation. The clearance of PF4 from the circulation of these rats (T1/2 = 45 min) fitted a single component model. We propose that PF4 is originally secreted by platelets into circulation and subsequently bound reversibly to vascular sites from which it can be released back into the circulation by heparin. The fast component of PF4 clearance that is abolished by heparin may reflect binding of this protein to the endothelial cells.

21. Differential requirements for platelet aggregation and inhibition of adenylate cyclase by epinephrine. Studies of a familial platelet alpha 2-adrenergic receptor defect

Rao, AK, Willis, J, Kowalska, MA, Wachtfogel, YT, and Colman, RW
- Abstract
We describe a family whose members have impaired platelet aggregation and secretion responses to epinephrine with normal responses to adenosine diphosphate and collagen. Platelet alpha 2-adrenergic receptors (measured using 3H methyl-yohimbine) were diminished in the propositus (78 sites per platelet), his two sisters (70 and 27 sites per platelet), and parents (37 and 63 sites per platelet), but not in two maternal aunts (12 normal subjects, 214 +/- 18 sites per platelet; mean +/- SE). However, the inhibition of cyclic adenosine monophosphate (cAMP) levels by epinephrine in platelets exposed to 400 nmol/L PGI2 was similar in the patients and five normal subjects (epinephrine concentration for 50% inhibition, 0.04 +/- 0.01 mumol/L v 0.03 +/- 0.01 mumol/L; P greater than .05). In normal platelets, the concentration of yohimbine (0.18 mumol/L) required for half maximal inhibition of aggregation induced by 2 mumol/L epinephrine was lower than that for inhibition of its effect on adenylate cyclase (1.6 mumol/L). In quin2 loaded platelets, thrombin (0.1 U/mL) stimulated rise in cytoplasmic Ca2+ concentration, [Ca2+]i, was normal in the two patients studied. The PGI2 analog ZK 36,374 completely inhibited thrombin-induced rise in [Ca2+]i; the reversal of this inhibition by epinephrine was normal in the two patients. Thus, despite the impaired aggregation response to epinephrine, platelets from these patients have normal ability to inhibit PGI2-stimulated cAMP levels. These patients with an inherited receptor defect provide evidence that fewer platelet alpha 2-adrenergic receptors are required for epinephrine-induced inhibition of adenylate cyclase than for aggregation.

22. Inhibition of collagen-induced platelet activation by 5'-p- fluorosulfonylbenzoyl adenosine: evidence for an adenosine diphosphate requirement and synergistic influence of prostaglandin endoperoxides

Colman, RW, Figures, WR, Scearce, LM, Strimpler, AM, Zhou, FX, and Rao, AK
- Abstract
The relative roles of platelet autacoids such as adenosine diphosphate (ADP), prostaglandin endoperoxides, and thromboxane A2 (TXA2) in collagen-induced platelet activation are not fully understood. We reexamined this relationship using the ADP affinity analogue, 5'-p- fluorosulfonylbenzoyl adenosine (FSBA), which covalently modifies a receptor for ADP on the platelet surface, thereby inhibiting ADP- induced platelet activation. Collagen-induced shape change, aggregation, and fibrinogen binding were each fully inhibited under conditions in which FSBA is covalently incorporated and could not be overcome by raising the collagen used to supramaximal concentrations. In contrast, TXA2 synthesis stimulated by collagen under conditions that produced maximum aggregation was only minimally inhibited by FSBA. Since covalent incorporation of FSBA has been previously shown to specifically inhibit ADP-induced activation of platelets, the present study supports the contention that ADP is required for collagen-induced platelet activation. Under similar conditions, indomethacin, an inhibitor of cyclooxygenase, inhibited collagen-induced shape change, indicating that endoperoxides and/or TXA2 also play a role in this response. Shape change induced by low concentrations (10 nmol/L) of the stable prostaglandin endoperoxide, azo-PGH2, was also inhibited by FSBA. These observations indicate a role for ADP in responses elicited by low concentrations of endoperoxides. However, at higher concentrations of azo-PGH2 (100 nmol/L), inhibition by FSBA could be overcome. Thus, the effect of collagen apparently has an absolute requirement for ADP for aggregation and fibrinogen binding and for both ADP and prostaglandins for shape change. Aggregation and fibrinogen binding induced by prostaglandin endoperoxides also required ADP as a mediator, but ADP is not absolutely required at high endoperoxide concentration to induce shape change.

- Abstract
An 82-year-old woman presented with extensive hematomas and melena associated with markedly decreased plasma factor V coagulant activity (FV:C). Using a competitive enzyme-linked immunosorbent assay developed in our laboratory, we made serial measurements of factor V antigen (FV:Ag) in plasma and found it to be normal or elevated. The patient's plasma was demonstrated to contain an IgG antibody that could neutralize FV:C in normal plasma. The antibody was of restricted heterogeneity (IgG1, IgG2,kappa). Circulating immune complexes containing antibody to factor V and FV:Ag were demonstrated directly in the plasma by immunoelectrophoresis with polyclonal monospecific antibody and with a monoclonal antibody using an enzyme-linked immunosorbent assay. Presence of neutralizing antibody could be demonstrated in vitro even at times when FV:C was within normal limits by heat inactivation of FV:C. Treatment with plasma and platelet transfusions as well as plasmapheresis induced definite but transient elevation of FV:C. Steroid therapy lowered the neutralizing antibody concentration and produced a rapid and persistent elevation of FV:C during two separate hospitalizations. This report describes a patient in whom levels of FV:Ag have been serially measured, and the presence of circulating immune complexes consisting of factor V and a neutralizing antibody have been directly demonstrated.

24. Platelet secretion defect associated with impaired liberation of arachidonic acid and normal myosin light chain phosphorylation

Rao, AK, Koike, K, Willis, J, Daniel, JL, Beckett, C, Hassel, B, Day, HJ, Smith, JB, and Holmsen, H
- Abstract
We describe four patients with impaired platelet aggregation and 14C- serotonin secretion during stimulation with adenosine diphosphate (ADP), epinephrine, collagen, and platelet-activating factor. The response to arachidonic acid was normal in all patients with regard to aggregation and in three of the four with regard to 14C-serotonin secretion. The total platelet adenosine triphosphate (ATP) and ADP content and the ATP to ADP ratio was normal in all patients, thereby excluding storage pool deficiency as the cause of the secretion defect. Studies with 3H-arachidonic acid-labeled platelets revealed that the thrombin-induced liberation of arachidonic acid from membrane-bound phospholipids was impaired in these patients. Further, platelet thromboxane B2 production, measured using a radioimmunoassay, was diminished during stimulation with ADP and thrombin, but was normal with arachidonic acid, indicating that the oxygenation of arachidonic acid was normal and that the diminished thromboxane production was due to a defect in the liberation of arachidonic acid. Release of arachidonic acid is mediated by phospholipases that are Ca++ dependent. To examine whether these patients may have a defect in making intracellular Ca++ available, another Ca++-dependent process, myosin light chain phosphorylation, was studied during thrombin stimulation. Platelets from three of the patients were found to behave the same as normal ones, suggesting that the deficiency in phospholipase activity may not be due to impaired Ca++ mobilization. Our studies demonstrate a novel group of patients with platelet secretion defects associated with impaired liberation of arachidonic acid from phospholipids. These patients exemplify a congenital defect, other than deficiencies of cyclooxygenase and thromboxane synthetase, by which thromboxane production may be impaired in platelets.

Koike, K, Rao, AK, Holmsen, H, and Mueller, PS
- Abstract
Platelet function was evaluated in 12 patients with the attention deficit disorder and lifelong history of easy bruising. Aggregation and 14C-serotonin secretion studies in platelet-rich plasma in response to adenosine diphosphate (ADP), epinephrine, and arachidonic acid did not reveal striking abnormalities. Secretion of adenosine triphosphate (ATP), ADP, beta-hexosaminidase, and beta-glucuronidase by gel-filtered platelets in response to the divalent cation ionophore A23187 and low concentrations of thrombin (less than or equal to 0.1 U/ml) was impaired in patients as compared to normals. The aggregation response to A23187 (4 microM) was absent in 8 of the 12 patients. The total stores of the secretable constituents, the retention of incorporated 14C-serotonin, and the arachidonate metabolism of the platelets were normal. Our findings suggest a new platelet disorder with impaired secretion mechanism, without storage pool deficiency or impaired arachidonate metabolism. The secretion defect in platelets represents a tissue disorder in a functional psychiatric disease. We refocus attention on the role of platelets as a model for neurons in functional disorders, with emphasis on secretion mechanisms rather than amine uptake, storage, and metabolism.

- Abstract
Defects in platelet cytoplasmic Ca++ mobilization have been postulated but not well demonstrated in patients with inherited platelet secretion defects. We describe studies in a 42-year-old white woman, referred for evaluation of easy bruising, and her 23-year-old son. In both subjects, aggregation and 14C-serotonin secretion responses in platelet-rich plasma (PRP) to adenosine diphosphate (ADP), epinephrine, platelet activating factor (PAF), arachidonic acid (AA), U46619, and ionophore A23187 were markedly impaired. Platelet ADP and adenosine triphosphate (ATP), contents and thromboxane synthesis induced by thrombin and AA were normal. In quin2-loaded platelets, the basal intracellular Ca++ concentration, [Ca++]i, was normal; however, peak [Ca++]i measured in the presence of 1 mmol/L external Ca++ was consistently diminished following activation with ADP (25 mumol/L), PAF (20 mumol/L), collagen (5 micrograms/mL), U46619 (1 mumol/L), and thrombin (0.05 to 0.5 U/mL). In aequorin-loaded platelets, the peak [Ca++]i studied following thrombin (0.05 and 0.5 U/mL) stimulation was diminished. Myosin light chain phosphorylation following thrombin (0.05 to 0.5 U/mL) stimulation was comparable with that in the normal controls, while with ADP (25 mumol/L) it was more strikingly impaired in the propositus. We provide direct evidence that at least in some patients with inherited platelet secretion defects, agonist-induced Ca++ mobilization is impaired. This may be related to defects in phospholipase C activation. These patients provide a unique opportunity to obtain new insights into Ca++ mobilization in platelets.

27. ADP-induced platelet shape change and mobilization of cytoplasmic ionized calcium are mediated by distinct binding sites on platelets: 5'- p-fluorosulfonylbenzoyladenosine is a weak platelet agonist
- Author

Rao, AK and Kowalska, MA
- Abstract
Platelet stimulation with ADP results in several responses, including shape change, increase in cytoplasmic ionized calcium concentration [Ca2+]i, an inhibition of adenylate cyclase. 5'-p-Fluorosulphonyl benzoyladenosine (FSBA), which covalently labels an ADP binding site on platelets, blocks platelet shape change but not the inhibition of cyclic AMP levels by ADP, whereas p-chloromercuribenzenesulfonate (pCMBS), a nonpenetrating thiol reagent, has the opposite effects. We examined the effect of FSBA and pCMBS on ADP-induced increase in [Ca2+]i using platelets loaded with fluorescent Ca2+ indicators quin2 and fura-2. FSBA (50 to 200 mumol/L) induced a dose-dependent rise in [Ca2+]i, indicating that it is a weak platelet agonist. Under conditions of covalent labeling of the ADP binding sites, FSBA (50 to 100 mumol/L) did not inhibit the ADP-induced increase in [Ca2+]i or its inhibition of adenylate cyclase, whereas pCMBS (up to 1 mmol/L) abolished both these responses but not shape change. These findings suggest that ADP-induced Ca2+ mobilization and inhibition of adenylate cyclase are mediated by platelet binding sites distinct from those mediating shape change.

- Abstract
We have purified a unique neutralizing IgG1, kappa monoclonal antibody (MAb) against factor V (F-V) from a patient's plasma. This MAb (H2) demonstrated specificity for human F-V heavy chain (D), mol wt 105,000. Using an enzyme-linked immunosorbent assay (ELISA) we assessed the competitive binding to F-Va of H2, H1 (human MAb directed to light chain, F1F2), and two murine MAbs, B38 (to F1F2) and B10 (to activation peptide C1). All four antibodies are of high affinity with KD varying from 0.17 to 1.17 X 10(-10) mol/L. They recognized distinct epitopes in F-V. F-Xa competed in a concentration-dependent fashion for binding of H1, H2, and B38 but not B10 to F-V/Va in the absence of phospholipids or platelets. Thus both F1F2 and D polypeptides of F-Va but not C1 interacted with F-Xa. All MAbs bound to F-V/Va in the absence of Ca++. However, free Ca++ (0.1 to 4.0 mmol/L) increased the amount of H1 and H2 bound to factor V/Va, 1.65-fold and 3.65-fold, respectively but had little effect on the binding of either murine MAbs. Prothrombin (20 micrograms/mL to 400 micrograms/mL) in the absence of phospholipid did not inhibit the binding of MAbs. These studies provide evidence for the first time for a direct interaction between human F-Va heavy chain and F-Xa and Ca++ and for the direct binding of F-Xa to F-Va in the absence of phospholipids or platelets and enhance our understanding of functional F-V domains.

Aerospace Engineering(Formerly Aeronautical Engineering) - Abstract
Interference fits are used extensively in aircraft structural joints because of their improved fatigue performance. Recent advances in analysis of these joints have increased understanding of the nonlinear load-contact and load-interfacial slip variations in these joints. Experimental work in these problems is lacking due to difficulties in determining partial contact and partial slip along the pin-hole interface. In this paper, an experimental procedure is enumerated for determining load-contact relations in interference/clearance fits, using photoelastic models and applying a technique for detecting progress of separation/contact up to predetermined locations. The study incorporates a detailed procedure for model making, controlling interference, locating break of contact up to known locations around the interface, estimating optically the degree of interference, determining interfacial friction and evaluating stresses in the sheet. Experiments, simulating joints in large sheets, were carried out under both pin and plate loads. The present studies provide load-separation behavior in interference joint with finite interfacial friction.

Aerospace Engineering(Formerly Aeronautical Engineering) - Abstract
The fatigue and fracture performance of a cracked plate can be substantially improved by providing patches as reinforcements. The effectiveness of the patches is related to the reduction they cause in the stress intensity factor (SIF) of the crack. So, for reliable design, one needs an accurate evaluation of the SIF in terms of the crack, patch and adhesive parameters. In this investigation, a centrally cracked large plate with a pair of symmetric bonded narrow patches, oriented normally to the crack line, is analysed by a continuum approach. The narrow patches are treated as transversely flexible line members. The formulation leads to an integral equation which is solved numerically using point collocation. The convergence is rapid. It is found that substantial reductions in SIF are possible with practicable patch dimensions and locations. The patch is more effective when placed on the crack than ahead of the crack. The present analysis indicates that a little distance inwards of the crack tip, not the crack tip itself, is the ideal location, for the patch.

Galactosyltransferase (UDPgalactose:glycoprotein galactosyltransferase EC 2.4.1.22) was isolated from swine mesentary lymhromatography on Sepharose 4B colums containing covalently bound p-aminophenyl-beta-D-N-acetylglucosamine. The homogenous enzyme showed a single band on disc gel electrophoresis and had a specific activity of 35 nmol min-1 (mg of protein)-1 at 37 degrees C. A molecular weight of 57 000 was obtained by exclusion chromatography, sucrose density centrifugation, and sodium dodecyl sulfate-gel electrophoresis. The same molecular weight was obtained after reduction and alkylation which indicates that the enzyme is composed of only a single polypeptide chain. The enzyme catalyzed the formation of beta1 leads to 4 bonds between galactose and free terminal N-acetylglucosaminyl residues of soluble preparations of porcine IgG immunoglobulin heavy chain, fetuin, ovalbumin, and ovomucoid. An endogenous glycoprotein, present in particulate subcellular preparations, was also a very good substrate for the enzyme, and it was identified as incomplete IgG immunoglobulin heavy chain. The Km of the purified enzyme was 2.9 x 10(-5) M for fetuin, 5.4 x 10(-5) M for ovalbumin, 2.0 x 10(-5) M for IgG immlnoglobulin heavy chain, and 2.2 x 10(-5) M for UDP-galactose. About 20% of the total galactosyltransferase activity in lymph node homogenates was present in the cytosol fraction, and 80% was in the microsomal and Golgi fractions. The kinetic properties of the bound and soluble galactosyltransferases were similar,and both required Mn2+ for maximal activity. However, the bound enzyme required the addition of detergent, lysolecithin, GDP-mannose, and UDP-N-acetylglucosamine for maximum activity. These compounds did not influence the activity of the soluble transferase. The membrane preparations catalyzed the transfer of galactose from UDP-galactose and N-acetylglycosamine from UDP-N-acetylglucosamine to incomplete oligosaccharide chains of endogenous IgG immunoglobulin bound to these particles. The labeled products of these reactions were isolated, and the structures of their oligosaccharide chains were determined and compared with those isolated from the heavy chain of porcine IgG immunoglobulin. The glycopeptide prepared from the endogenous acceptor and the major glycopeptide prepared by proteolytic digestion of the heavy chain of porcine IgG immunoglobulin has identical structures. The following structure for the carbohydrate chains of porcine IgG immunoglobulin was determined by sequential enzymatic hydrolysis and methylation studies.

Aerospace Engineering(Formerly Aeronautical Engineering) - Abstract
The Finite Element Method (FEM) has made a number of otherwise intractable problems solvable. An important aspect for achieving an economical and accurate solution through FEM is matching the formulation and the computational organisation to the problem. This was realised forcefully in the present case of the solution of a class of moving contact boundary value problems of fastener joints. This paper deals with the problem of changing contact at the pin-hole interface of a fastener joint. Due to moving contact, the stresses and displacements are nonlinear with load. This would, in general, need an interactive-incremental approach for solution. However, by posing the problem in an inverse way, a solution is sought for obtaining loads to suit given contact configuration. Numerical results are given for typical isotropic and composite plates with rigid pins. Two cases of loading are considered: (i) load applied only at the edges of the plate and (ii) load applied at the pin and reacted at a part of the edge of the plate. Load-contact relationships, compliance and stress-patterns are investigated. This paper clearly demonstrates the simplification achieved by a suitable formulation of the problem. The results are of significance to the design and analysis of fastener joints.

Aerospace Engineering(Formerly Aeronautical Engineering) - Abstract
The stress concentration that occurs when load is diffused from a constant stress member into thin sheet is an important problem in the design of light weight structures. By using solutions in biharmonic polar-trigonometric series, the stress concentration can be effectively isolated so that highly accurate information necessary for design can be obtained. A method of analysis yielding high accuracy with limited effort is presented for rectangular panels with transverse edges free or supported by inextensional end ribs. Numerical data are given for panels with length twice the width.

Historically, archaeological evidence, post-mortem findings and retro- spective analysis of leprosy institutions’ data demonstrates a high observed incidence of concomitant infection with leprosy and tuberculosis (TB). However, reports of concomitant infection in the modern literature remain scarce, with estimates of annual new case detection rates of concomitant infection at approximately 0·02 cases per 100,000 population. Whilst the mechanism for this apparent decline in concomitant infections remains unclear, further research on this topic has remained relatively neglected. Modelling of the interaction of the two organisms has suggested that the apparent decline in observations of concomitant infection may be due to the protective effects of cross immunity, whilst more recently others have questioned whether it is a more harmful relationship, predisposing towards increased host mortality. We review recent evidence, comparing it to previously held understanding on the epidemiological relationship and our own experience of concomitant infection. From this discussion, we highlight several under-investigated areas, which may lead to improvements in the future delivery of leprosy management and services, as well as enhance understanding in other fields of infection management. These include, a) highlighting the need for greater understanding of host immunogenetics involved in concomitant infection, b) whether prolonged courses of high dose steroids pre-dispose to TB infection? and, c) whether there is a risk of rifampicin resistance developing in leprosy patients treated in the face of undiagnosed TB and other infections? Longitudinal work is still required to characterise these temporal relationships further and add to the current paucity of literature on this subject matter.

The in vitro effect of fresh frozen plasma (FFP) on the whole blood activated coagulation time (ACT) was examined in 18 patients undergoing cardiopulmonary bypass (CPB) during coronary artery bypass graft surgery. The addition of FFP to whole blood in vitro, after systemic heparinization, significantly prolonged the ACT from 451 +/- 21 seconds (mean +/- SE) to 572 +/- 41 seconds (P less than 0.05). There was no significant correlation between the plasma antithrombin III activity and the prolongation in ACT after systemic heparinization, with or without addition of FFP. The addition of FFP to whole blood in three of the six patients who exhibited heparin resistance (ACT less than 400 seconds after administration of 350 unit/kg heparin) did not prolong the ACT to greater than 400 seconds. These observations suggest that infusion of FFP will further prolong the ACT after heparin administration in most patients including some with initial heparin resistance.

Abstract Background Free radical-induced oxidative stress is the root cause for many human diseases. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. The main objective of the present study was to characterize the antioxidant and antiproliferative potential of rice bran extracted from an important Indian rice variety, Njavara and to compare the same with two commercially available basmati rice varieties: Vasumathi, Yamini and a non medicinal variety, Jyothi. Methods Methanolic extracts of rice bran from four varieties; Vasumathi, Yamini, Jyothi and Njavara were used to study their total phenolic and flavonoid contents, in vitro antioxidant activities including total antioxidant activity, scavenging of nitric oxide and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical, reducing power and cytotoxic activity in C6 glioma cells. Correlation coefficient and regression analysis were done by using Sigmastat version 3.1 and Stata statistical package respectively. Results Rice bran methanolic extract from Njavara showed the highest antioxidant and cell cytotoxic properties compared to the other three rice varieties. IC50 values for scavenging DPPH and nitric oxide were in the range of 30.85-87.72 μg/ml and 52.25-107.18 μg/ml respectively. Total antioxidant activity and reducing power were increased with increasing amounts of the extract. Total phenolic and flavonoid contents were in the range of 3.2-12.4 mg gallic acid-equivalent (GAE)/g bran and 1.68-8.5 mg quercetin-equivalent (QEE)/g bran respectively. IC50 values of cytotoxic assay (MTT assay) were 17.53-57.78 μg/ml. Correlation coefficient and regression analysis of phenolic content with DPPH and NO scavenging, MTT (-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay, total antioxidant assay and reducing power showed a highly significant correlation coefficient values (96-99%) and regression values (91-98%). Conclusion The results of the present study show that the crude methanolic extract from Njavara rice bran contains significantly high polyphenolic compounds with superior antioxidant activity as evidenced by scavenging of free radicals including DPPH and NO. Njavara extracts also showed highest reducing power activity, anti-proliferative property in C6 glioma cells. In conclusion, it is conceivable that the Njavara rice variety could be exploited as one of the potential sources for plant - based pharmaceutical products.

- Abstract
OBJECTIVE: This study was undertaken to investigate the differences in perinatal outcomes among Asian American/Pacific Islander (AAPI) women. STUDY DESIGN: A retrospective cohort study of all Japanese, Chinese, and Filipina women who delivered at University of California, San Francisco from 1985 to 2001 examined the incidence of gestational diabetes, preeclampsia, and preterm delivery. RESULTS: Among the 6511 women delivered during the study period, the incidence of preeclampsia was highest among Filipina women (6.8%) compared with the Chinese and Japanese women (4.0% and 3.7%, respectively, P < .001). Gestational diabetes was most common in the Chinese and Filipina women (6.5% and 6.1%, respectively) compared with the Japanese women (3.4%, P = .013). Preterm delivery was also highest among Filipina women both before 37 weeks (12.2%, P < .001) and 34 weeks (4.8%, P = .004). These differences remained statistically significant after controlling for potential confounding variables. CONCLUSION: We found significant differences in rates of preeclampsia, gestational diabetes, and preterm delivery in the Chinese, Japanese, and Filipino subgroups. In studies of race and ethnicity, it is important to examine Asian subgroups separately. [ABSTRACT FROM AUTHOR]

WOS: 000379156300012, PubMed ID: 26819058, The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at (sic)23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients., Biotechnology and Biological Sciences Research CouncilBiotechnology and Biological Sciences Research Council (BBSRC) [BB/L023776/1, BB/I00050X/1, BB/K021168/1]; Cancer Research UKCancer Research UK [11831]; Medical Research CouncilMedical Research Council UK (MRC) [G1000801a]; Novo Nordisk FondenNovo Nordisk [NNF12OC1015986]; British Heart FoundationBritish Heart Foundation [FS/09/039/27788]; Cancer Research UKCancer Research UK [12765]; Medical Research CouncilMedical Research Council UK (MRC) [MR/L022982/1, MC_UU_12009/8, MC_U137981013, MC_PC_12009]

- Abstract
Background: Borealpox virus (BRPV, formerly known as Alaskapox virus) is a zoonotic member of the Orthopoxvirus genus first identified in a person in 2015. In the six patients with infection previously observed BRPV involved mild, self-limiting illness. We report the first fatal BRPV infection in an immunosuppressed patient., Methods: A man aged 69 years from Alaska's Kenai Peninsula was receiving anti-CD20 therapy for chronic lymphocytic leukemia. He presented to care for a tender, red papule in his right axilla with increasing induration and pain. The patient failed to respond to multiple prescribed antibiotic regimens and was hospitalized 65 days postsymptom onset for progression of presumed infectious cellulitis. BRPV was eventually detected through orthopoxvirus real-time polymerase chain reaction testing of mucosal swabs. He received combination antiviral therapy, including 21 days of intravenous tecovirimat, intravenous vaccinia immunoglobulin, and oral brincidofovir. Serial serology was conducted on specimens obtained posttreatment initiation., Findings: The patient's condition initially improved with plaque recession, reduced erythema, and epithelization around the axillary lesion beginning one-week post-therapy. He later exhibited delayed wound healing, malnutrition, acute renal failure, and respiratory failure. He died 138 days postsymptom onset. Serologic testing revealed no evidence the patient generated a humoral immune response. No secondary cases were detected., Conclusion: This report demonstrates that BRPV can cause overwhelming disseminated infection in certain immunocompromised patients. Based on the patient's initial response, early BRPV identification and antiviral therapies might have been beneficial. These therapies, in combination with optimized immune function, should be considered for patients at risk for manifestations of BRPV., (Published by Oxford University Press on behalf of Infectious Diseases Society of America 2024.)

- Abstract
Background: Phosphatidylserine (PS) is a procoagulant phospholipid enriched on surfaces of activated vascular cells including platelets, endothelium, monocytes, and microvesicles. As a molecular driver of thrombosis accessible to drug blockade, PS is an attractive pharmacologic target for modulating thrombogenesis, with potentially reduced bleeding risk compared to anticoagulant and antiplatelet therapies., Objectives: Test antithrombotic capabilities of a liposomal formulation, Zn-dipicolylamine cyanine-3[22,22]/1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (molar ratio, 3:97), designated as DPAL, which we previously described binds selectively to PS-enriched cell surfaces, compared with effects on bleeding, in mouse models., Methods: PS-dependent DPAL binding to human and murine platelets was tested in vitro. Thrombosis and bleeding after DPAL intravenous administration were tested in C57Bl/6J mice following FeCl
3 carotid arterial injury and tail tip amputation, respectively. Incorporation in hemostatic clots was investigated in the cremaster muscle laser injury model. Toxicity was tested by direct exposure to human endothelial cell cultures., Results: DPAL bound agonist-stimulated, PS-positive human and murine platelets, blocked by Annexin V or Ano6 deletion, which ablate PS exposure. DPAL prolonged prothrombin time, but did not prevent thrombin-induced fibrinogen receptor activation or aggregation, nor alter blood cell counts including platelets. Following arteriolar laser injury, DPAL bound wound surfaces and edges without destabilizing plugs. DPAL dose-dependently blocked FeCl3 -induced arterial thrombosis but did not substantially increase bleeding, or induce endothelial cell death., Conclusion: DPAL reduces thrombogenesis with minimal effects on bleeding in mouse models via selective binding to PS. DPAL may support novel approaches to modulate pathogenic thrombin generation with improved safety profiles in multiple contexts., Competing Interests: Declaration of competing interests L.E.G., J.G.T.W., X.Z., P.M., V.R., P.L.-G.C., M.T., F.D.C.-C., A.K.R., and S.E.M. declare no conflicts of interest.

- Abstract
Background: Multitarget stool DNA (MT-sDNA) tests (here, Cologuard®) are currently used in average-risk patients as a primary method of screening for colorectal cancer. However, MT-sDNA testing has also been used in patients who previously underwent colonoscopy who wish to avoid repeat colonoscopy. Here, in a large primary care practice setting, our aim was to evaluate the diagnostic performance of MT-sDNA testing in patients with a previously normal colonoscopy., Methods: This retrospective cohort study included 5827 patients from 35 different primary locations in South Carolina. Patients aged 45 and above with a previously documented normal, high-quality colonoscopy prior to the MT-sDNA test date were included. High-risk patients and those with a previous negative MT-sDNA result were excluded., Results: Of 5827 ordered MT-sDNA tests, 248 patients had a prior normal colonoscopy. The average time from initial colonoscopy to MT-sDNA testing was 7.3 years. Of the 63 patients who had a positive MT-sDNA test, 41 patients (65%) completed follow-up colonoscopy and 40 patients had complete colonoscopy data. Of these 40 patients, 12 patients (30%) had advanced adenomas and none had colorectal cancer. Compared to patients without a previous colonoscopy, patients with prior colonoscopies had fewer adenomas of all types (1.6 vs 2.4) and fewer advanced adenomas (1.4 vs 2.0)., Conclusion: Patients with a previously negative colonoscopy and subsequent positive MT-sDNA test were found to have a high rate of advanced adenomas on follow-up colonoscopy (30%). Thus, in patients with a previously negative colonoscopy, MT-sDNA testing may be a reasonable alternative screening option., (© 2024.

- Abstract
The antiviral drug tecovirimat* has been used extensively to treat U.S. mpox cases since the start of a global outbreak in 2022. Mutations in the mpox viral protein target (F13 or VP37) that occur during treatment can result in resistance to tecovirimat
† (1,2). CDC and public health partners have conducted genetic surveillance of monkeypox virus (MPXV) for F13 mutations through sequencing and monitoring of public databases. MPXV F13 mutations associated with resistance have been reported since 2022, typically among severely immunocompromised mpox patients who required prolonged courses of tecovirimat (3-5). A majority of patients with infections caused by MPXV with resistant mutations had a history of tecovirimat treatment; however, spread of tecovirimat-resistant MPXV was reported in California during late 2022 to early 2023 among persons with no previous tecovirimat treatment (3). This report describes a second, unrelated cluster of tecovirimat-resistant MPXV among 18 persons with no previous history of tecovirimat treatment in multiple states., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Rao AK, Nguyen TMT, Magri JB, and Mathews JW
- Abstract
Adrenal adenomas are benign tumors of the adrenal cortex that may secrete excess hormones, such as cortisol. They are most commonly discovered during imaging studies for unrelated problems. Lipomatous metaplasia is a rare degenerative change in adrenal adenomas, characterized by the presence of adipose tissue and hematopoietic elements within the tumor. In this report, we present a case of an adrenal adenoma with lipomatous metaplasia in a patient with hypertension, hyperlipidemia, and type II diabetes mellitus. The discovery of this adrenal mass was prompted by an evaluation of the patient's progressive hirsutism. The tumor was found to be secreting cortisol, leading to Cushing syndrome. The patient subsequently underwent surgical resection of the mass after being treated with mifepristone. The histopathological examination confirmed it to be an adrenal cortical neoplasm with lipomatous metaplasia, characterized by uncertain malignant potential. The patient did well postoperatively. Three months after left adrenalectomy, the patient's hirsutism, A1c, and hypertension improved, allowing a reduction in antihypertensives. Her body mass index stabilized, her triglyceride decreased, and her dehydroepiandrosterone sulfate level normalized. She continued to do well at follow-up visits. Overall, this was a rare case of a functioning adrenal adenoma with lipomatous metaplasia, presenting both diagnostic and therapeutic challenges., (© The Author(s) 2024.

- Abstract
Background: During the ongoing outbreak of clade II monkeypox virus (MPXV), many U.S. patients were prescribed tecovirimat, an antiviral drug that was made available under an expanded access Investigational New Drug (EA-IND) program. We evaluated EA-IND data to summarize characteristics of treated patients, outcomes, and serious adverse events (SAEs)., Methods: We evaluated data from patients prescribed tecovirimat from May 29, 2022, through July 10, 2023. Baseline patient characteristics, clinical courses, and outcomes were evaluated via intake forms, outcome forms, and patient diaries. Data were summarized in aggregate by human immunodeficiency virus (HIV) status and by comorbidities of special interest. Reported SAEs were also compiled., Results: Tecovirimat was prescribed for over 7100 patients in the United States, most often for lesions in sensitive anatomical areas, such as certain anogenital lesions (83.5%; 5135 out of 6148 patients), and pain (52.5%; 3227 out of 6148 patients). The demographic and clinical characteristics mirrored those of patients worldwide. Among the 7181 patients with returned intake forms, 1626 also had returned outcome forms (22.6%). Many patients with severe immunocompromise (e.g., HIV with CD4 counts <200 cells/μl) received multiple courses of tecovirimat (43.1%; 22 out of 51 patients), including intravenously, and often experienced poor outcomes (35.3%; 18 out of 51 patients). Overall, 223 SAEs and 40 deaths were reported. Most SAEs were among patients who were severely immunocompromised, one of whom experienced hallucinations after tecovirimat was administered at twice the standard dose., Conclusions: Tecovirimat was used extensively. The returned EA-IND data suggest that life-threatening or protracted infections occurred in persons who were severely immunocompromised. SAEs were not commonly reported. The EA-IND data are not definitive; controlled clinical trial data are essential to elucidating if and how tecovirimat should be used.
