Abstract

Objectives: The aim of this study was to compare operative data and postoperative complications among nondescent vaginal hysterectomy (NDVH), laparoscopy-assisted vaginal hysterectomy (LAVH), and total laparoscopic hysterectomy (TLH) at a rural tertiary care center. Materials and Methods: This is a prospective analytical study, of 145 hysterectomies for benign conditions with or without salpingo-oophorectomy in women from 30 to 60 years, over 3 years from January 2016 to December 2019, with 60 cases of NDVH, 46 cases of LAVH, and 39 cases of TLH. The three groups were compared intraoperatively in terms of blood loss, operating time, and intraoperative complications and postoperative complications and postoperative duration of hospital stay. Results: There was no significant difference between the three groups in terms of age, parity, body mass index, and indications for hysterectomies. The mean operative time was significantly shorter (P = 0.000) in the NDVH group (54.67 ± 15.67 min) as compared to the LAVH (102.45 ± 10.53 min) and TLH (126.79 ± 8.7 min) groups. Intraoperative blood loss was greater (P = 0.000) in the TLH group (111.025 mL ± 20.8) as compared to the NDVH (59.50 mL ± 16.7) and LAVH (91.85 mL ± 10.66) groups. The intraoperative complications and postoperative complications were higher in the TLH group as compared to the LAVH and NDVH groups. The duration of hospital stay was almost similar in all the groups. Conclusion: NDVH may be the preferred approach for experienced surgeons, as it is less time-consuming, has a small amount of blood loss, and is a scarless surgery, whereas LAVH and TLH may be the preferred approaches in the cases of presence of adnexal masses and adhesions or whenever salpingo-oophorectomy is indicated.

Abstract

We introduce a novel task execution capability that enhances the ability of in-situ crew members to function independently from Earth by enabling safe and efficient interaction with automated systems. This task execution capability provides the ability to (1) map goal-directed commands from humans into safe, compliant, automated actions, (2) quickly and safely respond to human commands and actions during task execution, and (3) specify complex motions through teaching by demonstration. Our results are applicable to future surface robotic systems, and we have demonstrated these capabilities on JPL's All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) robot.

Author

Preeti and Verma, Vandana

Abstract

Employees are the key elements of any organization. The motivated employees are keen to display the artistic picture of the organization by accomplishing better perspective and executing greater results. Motivation refers to the reasons that underlie behavior; that is characterized by willingness and volition. Intrinsic motivation is animated by personal enjoyment, interest, or pleasure, whereas extrinsic motivation is governed by reinforcement contingencies. Employee motivation is extrinsic motivation. In the era of globalization; the companies are facing heavy competitions and working within high pressure and tense working environment and to tackle the pressure employees needs to get motivated and activated. The capabilities of increasing productivity and enhancing working skills of individual, groups as well as organization with the help of different guidance and theories to accomplish high performance and increasing driving capacity of the organization. The work-life balance, career goals and stress management aspects are needed to be deployed to engage employees in the organization by motivational approaches. [ABSTRACT FROM AUTHOR]

Abstract

Background of the Study: Ayurveda has described eight kinds of honey with the different medicinal values that get change with the passage of time of one year. Pauttika honey is a specific kind of honey among the eight types of honey produced by Pauttika honey bee, which is indicated in the management of diabetes (Prameha), obesity (Sthaulaya), dyslipidemia, etc. Objective: To identify and standardize the type of honey and its honey bee on scientific parameters and the characteristics as mentioned in Ayurveda. Materials and Methods: Honey was procured from the natural honey hive and Standard methods were used for physico-chemical analysis, sensory evaluation, and color hunter test. Bee identification was done by an expert entomologist. Results: Analysis of honey, showed that procured honey was Pauttika type of honey as described in Ayurveda and bee was identified as Apis dorsata. Researchers also found some changes in the properties of honey after the one year like in pH, HMF, Color, and Sensory evaluation. Conclusion: The Physico-chemical analysis of honey samples confirmed the good quality of Pauttika honey produced by Apis dorsata also confirms a new variety of honey as mentioned in Ayurveda.

Abstract

Holistic biology of Ayurveda is based on Triguna, Tanmatra, Tridosh, Saptadhatu, Oja, Agni, Ama and Srotas. Srotas are the in ner transport system of the body which provide plat form for activities of other i mportant bio - factors like three dosh, the seven dhatu, the oja, the agni etc. In Ayurvedic classics the term Srotas is used as dynamic inner transport system of body - mind - spirit organization in addition to circulatory system. Ayurvedic Acharyas have descri bed that the entire range of life processes in health and disease depends on integrity of the srotas system which is prone to lose its integrity due to out of order lifestyle and faulty food. There is a need to study the fundamental and applied aspect of s rotas in order to understand Ayurvedic biology and disease processes in depth.

Abstract

Introduction: In a developing country like India, tuberculous lymphadenitis is one of the most common presentations at OPDs. However, anti-tubercular treatment cannot be administered only on clinical suspicion. Cytomorphology with acid fast staining proves to be a valuable tool in diagnosing these cases along with culture. The study was undertaken to study the utility, limitations of fine needle aspiration cytology and various cytomorphological presentations in reference to Ziehl-Neelsen staining in tuberculous lymphadenitis and correlate the culture findings. Methods: The study was conducted for duration of two years with total of 170 cases at a tertiary care centre. The patients with clinically suspected lymphadenopathy were selected. Results: The incidence of tuberculous lymphadenitis was 68.8%. Overall AFB positivity was 64.1 %. Epithelioid cell granulomas with lymphocytes were the most common cytological picture and cases showing necrosis had highest AFB positivity. Maximum patients presented in second to fourth decade of life. Cervical region was the most common site of involvement with solitary lymphadenopathy as the most common presentation in contrast to matted lymph nodes as reported by others. Conclusion: Yet again Fine needle aspiration cytology is a safe, cheap and reliable procedure requiring minimal instrumentation and is highly sensitive to diagnose tuberculous lymphadenitis. The diagnostic index can be further increased by complementing cytomorphology with acid fast staining and culture techniques. However FNAC complimented with techniques like ELISA and PCR would give better dimensions to the current scenario of diagnosis and treatment modalities.

Abstract

Objective— The gap junction protein connexin37 (Cx37) plays an important role in cell-cell communication in the vasculature. A C1019T Cx37 gene polymorphism, encoding a P319S substitution in the regulatory C terminus of Cx37 (Cx37CT), correlates with arterial stenosis and myocardial infarction in humans. This study was designed to identify potential binding partners for Cx37CT and to determine whether the polymorphism modified this interaction. Methods and Results— Using a high-throughput phage display, we retrieved 2 binding motifs for Cx37CT: WHK … [K,R]XP … and FHK … [K,R]XXP … , the first being more common for Cx37CT-319P and the second more common for Cx37CT-319S. One of the peptides (WHRTPRLPPPVP) showed 77.7% homology with residues 843 to 854 of endothelial nitric oxide synthase (eNOS). In vitro binding of this peptide or of the homologous eNOS sequence to both Cx37CT isoforms was confirmed by cross-linking and surface plasmon resonance. Electrophysiological analysis of Cx37 single channel activity in transfected N2a cells showed that eNOS-like and eNOS(843–854) increased the frequency of events with conductances higher than 300 pS. We demonstrated that eNOS coimmunoprecipitated with Cx37 in a mouse endothelial cell (EC) line (bEnd.3), human primary ECs, and a human EC line transfected with Cx37-319P or Cx37-319S. Cx37 and eNOS colocalized at EC membranes. Moreover, a dose-dependent increase in nitric oxide production was observed in ECs treated with Cx37 antisense. Conclusion— Overall, our data show for the first time a functional and specific interaction between eNOS and Cx37. This interaction may be relevant for the control of vascular physiology both in health and in disease.
