Logistics today has been an integral part of the world, responsible for major trades of goods, medicines, products, and services. However, logistics face a big problem when it comes to goods that require a constant or a near about temperature to be maintained while being on the road. Using a temperature control system can help largely reduce the problem, thus saving time, money, and resources. The proposed container can be used to store temperature sensitive items such as medicines or general purpose/day to day items or food and beverages. In this paper, we discuss a temperature-controlled container that can be used to transport such temperature sensitive items. The main technology being used in the container would be thermoelectric Peltier (TEC). The container shall be user controlled via a keypad accompanied with several safety features such as over temperature protection, emergency shutdown button, display to view the current/set temperatures and have a docked/portable power supply system. The power supply and power converter for the board has been made completely in-house using detailed PCB's. Calculations for the power requirement and its efficiency have been discussed in depth. Such a product shall provide great help to logistics and medical industry. Material of the box (HDPE) could sustain wide temperature changes and the efficiency of the overall system was 70 percent.

Avian cellulitis is one of the most important field problems facing the poultry sector. Sever financial losses resulted from the condemnation of the broiler carcasses infected with cellulitis lesions. In light of this, the current study was aimed to isolation and identification of the bacterial species causing cellulitis in broiler chickens in Dakahlia and Sharkia Governorates, Egypt. The bacterial isolates were tested for their antimicrobial susceptibility and molecular detection of some virulence and antimicrobial resistance genes. In addition to evaluate the antibacterial activity of quaternary ammonium compounds and glutaraldehyde (TH4 ®) against the bacterial isolates. Four bacterial species were isolated; E. coli, S. aureus, P. aeruginosa and Proteus mirabilis with percentages of (75%), (20%), (6%) and (5%) respectively. E. coli was recorded as the most predominant isolated bacteria in this study with12 different sero- groups (O1, O2, O26, O55, O78, O91, O121, O125, O126, O128, O153 and O158). E. coli O78 and O91 were the most prevalent identified sero- groups. The antimicrobial susceptibility testing revealed higher resistances against doxycycline and ampicillin (95.6%), amoxicillin (90.7%), norfloxacin (84%), oxytetracycline (79.1%) and amikacin (71.6%) in E. coli, doxycycline (73.3%), oxytetracycline (80%),ampicillin(75%), streptomycin (80%), erythromycin (73.3%), and oxacillin (86.7%) in S. aureus, doxycycline (83.3%), oxytetracycline (77.8%), ampicillin (83.3%), amoxicillin (88.9%), neomycin (72.2%) and erythromycin (77.8%) in P. aeruginosa and doxycycline, oxytetracycline, ampicillin, amoxicillin, streptomycin and erythromycin (100% for each of them) in Proteus mirabilis. All isolated bacterial species were multidrug resistance (MDR). The molecular identification showed the detection of virulence genes: iutA in E. coli, nuc in S. aureus, toxA in P. aeruginosa and rsbA in Proteus mirabilis., with percentage of (100%). blaTEM, tetA (A), qnrA, tetK, mecA, aac(6') aph (2"), ereA and aada1 resistance genes were reported in this study. Quaternary ammonium compounds in combination glutaraldehyde (TH4 ®) with 2% concentration showed the highest antibacterial activity against the examined multidrug resistant bacterial isolates. These results suggested for application of 2% TH4 ® to achieve effective disinfectant programs in poultry farms. [ABSTRACT FROM AUTHOR]

Constructivism serves as a basic theory in education, and plays an important role, because this perspective views learning as a dynamic process in which students actively participate in constructing their knowledge. So, this research aims to produce a virtual laboratory that is valid and effective in developing constructivist thinking. This research and development use the Ploom approach which consists of initial investigation, design, construction/realization, testing, evaluation, revision, and implementation. Thirty-two electrical engineering students from Padang State University participated in this research. The instruments used are validity instruments and constructivism assessment tools. The research results show that the Proteus-based virtual laboratory developed is valid and effective in fostering constructivist thinking in electrical measurement practice. This study contributes to the advancement of virtual laboratories in educational settings, emphasizing the importance of constructivist pedagogy for meaningful and engaging learning experiences in the field of electrical engineering. The results of this research open opportunities for further research regarding the exploration of artificial intelligence to improve constructivism through virtual laboratories.

Background: An increasing number of drugs are used each year in the treatment of small pets (cats and dogs), including medicines (cephalosporins and fluoroquinolones) used in human therapy. Aim: The purpose of this study was to isolate and explore the antibiotic resistance of opportunistic Enterobacteriaceae (Escherichia coli, Klebsiella, Proteus, Ci trobacter, Enterobacter) from cats and dogs, and to isolate resistance genes in the microorganisms. Methods: In 2021, 808 samples of biological material from small domestic animals were collected in veterinary clinics in Kostanay. From these, 210 microorganisms were isolated and identified. Results: A large majority of the strains sampled belonged to E. coli-149 (70.9%), Enterobacter-11 (5.2%), Klebsiella-28 (13.3%), Proteus-12 (5.7%) and 10 Citrobacter isolates (4.8%). In all isolates identified, antibiotic resistance/sensitivity was determined by disc-diffusion method to ampicillin, cefoxitin, gentamicin, levomycetin, tetracycline, ciprofloxacin, norfloxacin, ofloxacin, cefoperazone, cefpodoxime, streptomycin, kanamycin, doxycycline, gemifloxacin, nalidixic acid, furazolidone, furadonine, amoxicillin, and enrofloxacin. Conclusion: The study has demonstrated that the greatest number of Enterobacteriaceae were sensitive to the action of meropenem, which belongs to the group of beta-lactam antibiotics; resistance was demonstrated against tetracycline, doxycycline, ampicillin, amoxicillin, ofloxacin, and cefpodoxime. The most common genes encoding antimicrobial resistance were as follows: BlaTEM and OXA in 41 and 28 isolates, respectively, encoding resistance to beta-lactams; StrA and StrB in 45 and 48 isolates encoding aminoglycosides; and tetA and tetB in 43 and 28 isolates encoding tetracyclines. Obtained data demonstrate that uncontrolled and frequent use of beta-lactam and tetracycline antibacterials, in cats and dogs, results in the spread of genotypic resistance among micro-organisms of the family Enterobacteriaceae.

The increasing adoption of electric vehicles (EVs) presents a promising solution for achieving sustainable transportation and reducing carbon emissions. To keep pace with technological advancements in the vehicular industry, this paper proposes the development of a hybrid energy storage system (HESS) and an energy management strategy (EMS) for EVs, implemented using Proteus Spice Ver 8. The HESS consists of a proton exchange membrane fuel cell (PEMFC) as the primary source and a supercapacitor (SC) as the secondary source. The EMS, integrated into an electronic board based on the STM32, utilizes a low-pass filter algorithm to distribute energy between the sources. The accuracy of the proposed PEMFC and SC models is validated by comparing Proteus simulation results with experimental tests conducted on the Bahia didactic bench and Maxwell SC bench, respectively. To optimize energy efficiency, simulations of the HESS system involve adjusting the hybridization rate through changes in the cutoff frequency. The analysis compares the state-of-charge (SOC) of the SC and the voltage efficiency of the fuel cell (FC), across different frequencies to optimize overall system performance. The results highlight that the chosen strategy satisfies the energy demand while preserving the FC's dynamic performance and optimizing its utilization to the maximum. [ABSTRACT FROM AUTHOR]

Bronchiectasis is irreversible bronchial dilation that can be congenital or acquired secondary to chronic airway obstruction. Feline bronchiectasis is rare and, to our knowledge, has not been reported previously in a non-domestic felid. An ~10-y-old female jungle cat (Felis chaus) was presented for evaluation of an abdominal mass and suspected pulmonary metastasis. The animal died during exploratory laparotomy and was submitted for postmortem examination. Gross examination revealed consolidation of the left caudal lung lobe and hila of the cranial lung lobes. Elsewhere in the lungs were several pale-yellow pleural foci of endogenous lipid pneumonia. On cut section, there was severe distension of bronchi with abundant white mucoid fluid. The remaining lung lobes were multifocally expanded by marginal emphysema. Histologically, ectatic bronchi, bronchioles, and fewer alveoli contained degenerate neutrophils, fibrin, and mucin (suppurative bronchopneumonia) with rare gram-negative bacteria. Aerobic culture yielded low growth of Proteus mirabilis and Escherichia coli. There was chronic bronchitis, marked by moderate bronchial gland hyperplasia, lymphoplasmacytic inflammation, and lymphoid hyperplasia. The palpated abdominal mass was a uterine endometrial polyp, which was considered an incidental, but novel, finding. Chronic bronchitis and bronchopneumonia should be considered as a cause of bronchiectasis and a differential diagnosis for respiratory disease in non-domestic felids. [ABSTRACT FROM AUTHOR]

Background: Orthokeratology (OK) lens wear increases the risk of bacterial infection, but little is known about the microbiota of the conjunctival sac in myopic children wearing OK lenses. This study aimed to investigate the changes of conjunctival microbiota in children after treatment with OK lenses using 16 S rDNA sequencing. Methods: Twenty-eight myopic children who had been continuously wearing OK lenses for 12 to 13 months were enrolled in this prospective study. Twenty-two gender- and age-matched myopic children who had not worn OK lenses or discontinued OK lens wear at least 1 year ago were recruited as controls. Conjunctival swabs from each participant were collected for exploration of the microbiota profiles, targeting the V3–V4 regions of the 16 S rRNA gene by MiSeq sequencing. The differences in the microbial community structure and diversity were also compared between groups. Results: The bacterial alpha diversity indices in the OK lens group were not different from those in the non-wearer group (P > 0.05, Wilcoxon test), while beta diversity examined using principle coordinate analysis of unweighted UniFrac divided the two groups into different clusters. Proteobacteria, Bacteroidetes, and Firmicutes were the abundant phyla in the conjunctival sac microbiota in both groups (P < 0.05, Mann–Whitney U test). Among children in the OK lens group, the Linear discriminant analysis Effect Size identified the compositional changes in OK lens-associated bacteria. Key functional genera such as Blautia, Parasutterella, and Muribaculum were enriched, whereas Brevundimonas, Acinetobacter, Proteus, and Agathobacter decreased significantly (P < 0.05, Mann–Whitney U test). Phylogenetic investigation of communities by reconstruction of unobserved states also showed altered bacterial metabolic pathways in OK lens-associated microbiota. Moreover, using receiver operating characteristic curves, Brevundimonas, Acinetobacter, Proteus, and Agathobacter alone (the area under the curve was all > 0.7500) or in combination (the area under the curve was 0.9058) were revealed to discriminate OK lens wearers from controls. Conclusions: The relative abundance of the microbial community in the conjunctival sac of myopic children can alter after OK lens wear. Brevundimonas, Acinetobacter, Proteus, and Agathobacter may be candidate biomarkers to distinguish between OK lens wearers and non-wearers. [ABSTRACT FROM AUTHOR]

To investigate the acquisition and relatedness of New Delhi Metallo-beta-lactamase among multiple separate species from one patient. Five isolates from three species (Pseudomonas aeruginosa; Pa, Acinetobacter baumannii; Ab and Proteus mirabilis; Pm) suspected of harbouring a carbapenemase were investigated by phenotype (antimicrobial susceptibilities) and whole genome sequencing. Epidemiological data was collected on this patient. Three different carbapenemase genes were detected; blaVIM-1 (Pa; ST773), blaOXA-23 (Ab, ST499) and blaNDM-1 identified in all isolates. NDM regions were found chromosomally integrated in all isolates. Data showed no evidence of NDM-1 transfer within this patient suggesting the enzyme was acquired in three separate events.

Extensively drug-resistant (XDR), multidrug-resistant (MDR) and pandrug-resistant (PDR) Gram-negative microorganisms (GNBs) are considered a significant global threat. β-lactam and aminoglycoside combinations and imipenem:cyclodextrin inclusion complexes were studied for the treatment of lethal GNBs. This is because of the broad empiric coverage of the two drugs and their possession of different spectra of activity. Two cyclodextrins (β- and hydroxy propyl β-cyclodextrins) were utilized for inclusion complex formation with imipenem using the physical and kneading methods. In silico investigation using the molecular docking and Fourier-infrared spectroscopy (FTIR) were employed to estimate binding constant and confirm complex formation, respectively. The in vitro effects of amikacin and imipenem combination in comparison to the effect of imipenem-β- and hydroxy propyl β-cyclodextrin (CD) complexes against Klebsiella spp. and Acinetobacter baumannii were studied. The isolated microorganisms' antimicrobial responsiveness to various antibiotics (19 antibiotics) was evaluated. It was found that piperacillin/tazobactam and gentamycin (resistance rates were 33.3% and 34%, respectively) were the most effective antimicrobials. The in vitro studies have been performed by the checkerboard technique and time-killing assay. The studied combination of amikacin and imipenem showed a substantial drop in bacterial count (p < 0.05). The in vitro studies demonstrated a synergism for the investigated combination. Conventional PCR was used in molecular studies to identify the resistance genes bla IMP and aac (6′)-Ib. The blaIMP and aac (6′)-Ib were recorded in 38.2% and 3.6% of the studied isolates, respectively. The in vitro studies showed synergistic effects among the tested antibiotics with FICIs of ≤0.5. Finally, the study compared the reduction in bacterial count between the tested antibiotic combinations and imipenem:CD physical and kneaded mixtures. Imipenem:CD inclusion complexes demonstrated a significant bacterial count reduction over the antibiotic combination. These results highlight the emerging role of CDs as safe biofunctional excipients in the combat against superbug bacterial resistance. [ABSTRACT FROM AUTHOR]

We introduce a new flexible one-dimensional photochemical model named Photochemical and RadiatiOn Transport model for Extensive USe (PROTEUS), which consists of a Python graphical user interface (GUI) program and Fortran 90 modules. PROTEUS is designed for adaptability to many planetary atmospheres, for flexibility to deal with thousands of or more chemical reactions with high efficiency, and for intuitive operation with GUI. Chemical reactions can be easily implemented into the Python GUI program in a simple string format, and users can intuitively select a planet and chemical reactions on GUI. Chemical reactions selected on GUI are automatically analyzed by string parsing functions in the Python GUI program, then applied to the Fortran 90 modules to simulate with the selected chemical reactions on a selected planet. We performed a benchmark test of PROTEUS to confirm its validity, by applying it to the Martian atmosphere and the Jovian ionosphere. PROTEUS can significantly save the time for those who need to develop a new photochemical model; users just need to write chemical reactions in the Python GUI program and just select them on GUI to run a new photochemical model.

Bovine mastitis is a polymicrobial disease characterised by inflammation of the udders of dairy and beef cattle. The infection has huge implications to health and welfare of animals, impacting milk and beef production and costing up to EUR 32 billion annually to the dairy industry, globally. Bacterial communities associated with the disease include representative species from Staphylococcus, Streptococcus, Enterococcus, Actinomyces, Aerococcus, Escherichia, Klebsiella and Proteus. Conventional treatment relies on antibiotics, but antimicrobial resistance, declining antibiotic innovations and biofilm production negatively impact therapeutic efficacy. Bacteriophages (phages) are viruses which effectively target and lyse bacteria with extreme specificity and can be a valuable supplement or replacement to antibiotics for bovine mastitis. In this review, we provide an overview of the etiology of bovine mastitis, the advantages of phage therapy over chemical antibiotics for the strains and research work conducted in the area in various model systems to support phage deployment in the dairy industry. We emphasise work on phage isolation procedures from samples obtained from mastitic and non-mastitic sources, characterisation and efficacy testing of single and multiple phages as standalone treatments or adjuncts to probiotics in various in vitro, ex vivo and in vivo bovine mastitis infection models. Furthermore, we highlight the areas where improvements can be made with focus on phage cocktail optimisation, formulation, and genetic engineering to improve delivery, stability, efficacy, and safety in cattle. Phage therapy is becoming more attractive in clinical medicine and agriculture and thus, could mitigate the impending catastrophe of antimicrobial resistance in the dairy sector.

Pericarditis means inflammation in the pericardial sac. Pericarditis is divided into three categories based on morphology, including fibrinous, purulent, and constrictive. In the present study, a 7‐month‐old male Ghezel breed sheep was examined for low weighting rate for three months. Tachypnea, tachycardia, heart friction sound, absence of fever and normal appetite were recorded in the clinical examination. In the patient's history, there was a history of perforated chest trauma behind the left scapula about three months ago. After the echocardiography examination and bacteriology procedures, purulent pericarditis caused by Proteus mirabilis was diagnosed. The bacterium was analysed using genome sequencing and new strain called Abhar114 was diagnosed. This is the first report of pericarditis caused by Proteus mirabilis in sheep. [ABSTRACT FROM AUTHOR]

One of the most common causes of urinary tract infections (UTIs) is Proteus species. Because there is little information on the pathogenicity of Proteus species isolated from Iran, we assessed their virulence characteristics and antibiotic resistance in this study. In Shahrekord, Iran, 260 isolates of Proteus causing UTIs were identified from patients. Polymerase chain reaction for gene amplification was used to determine virulence features and antibiotic resistance gene distribution in uropathogenic Proteus spp. After biochemical and molecular analysis, 72 (27.69%) of the 260 collected samples were recognized as Proteus mirabilis , and 127 (48.84%) specimens were Pr. vulgaris in both male and female forms. A significant interaction effect between Pr. mirabilis and Pr. vulgaris infections and the sex of patients was seen in both the male and female groups. No statistically significant difference was observed between Pr. mirabilis infection and season in different year seasons. However, in different seasons of the year, a statistically significant difference was observed between infection with Pr. vulgaris in autumn and other seasons. There was a considerable difference between Pr. mirabilis and Pr. vulgaris infections at different ages in various age groups. As people aged, infections occurred more frequently. Fim,pap,kspMT , and set1 genes had the highest expression in both Pr. vulgaris and Pr. mirabilis. Also, the highest rate of antibiotic resistance of Pr. vulgaris and Pr. mirabilis is attributed to the high expression of aac(3)-IV,tet(A) , and blaSHV genes. In conclusion, identifying these genes as the key controllers of Proteus virulence factors might help with better infection management. [ABSTRACT FROM AUTHOR]

This article is a transcript of the third session of a reading group on James Joyce's Ulysses run by the five lizards who guard the grave of Joyce in Zürich. The third chapter of Ulysses is "Proteus," in which the character Stephen Daedalus strides across Sandymount Strand meditating upon the "ineluctable modality of the visible" and his own variegated processes of perception as he takes in the sea and the beach. Each lizard articulates a different perspective on sensory perception and a different modality of reading directed by that perspective, and so the lizards cannot agree on what the focus of their discussion should be. As the lizards become more creatively inspired, several other characters appear and add their own perspective, and through the liveliness of conversation and the difference of voices there emerges a kind of "chameleonics" in which multicolored light is projected from within the bodies of each lizard. The mobilization of creativity in this discussion aims to open out the "ineluctable modality of the visible" occurring in the first sentence of Joyce's chapter into a sensory manifold that both plays and is played by the voices of the meteorological forces themselves that render the seascape protean.

Background: Among Gram-negative bacteria, the presence of beta-lactamases is a defined modality of resistance to antibiotics of the beta-lactam group. Proteus species also has been showing various degrees of resistance to these groups of antibiotics and thereby appearing multidrug resistant. The aim of our study was to know the occurrence of Proteus species from different clinical samples their antibiotic susceptibility, extended-spectrum β-lactamase (ESBL) production, and the associated patient risk factors. Materials and Methods: This observational descriptive study was done from December 2020 to December 2021. All Proteus isolates obtained from various clinical samples, were biochemically identified, antibiogram, and screening for ESBL production was done using a combination of cefotaxime and cefotaxime clavulanic acid antibiotic discs. Results: Seventy-nine Proteus isolates were obtained from hospitalized patients. In that, Proteus mirabilis was the most common isolate followed by Proteus vulgaris. Proteus infections were common in the age groups of 41--60 years and males were affected more than females. Out of the 79 Proteus isolates 12 were ESBL producers. Among these, 25% of ESBL producers were P. mirabilis and 75% of them were P. vulgaris. Conclusion: The most common isolate was P. mirabilis among hospitalized patients and P. vulgaris was the main ESBL producers when compared to P. mirabilis. These pathogens mainly caused wound and urinary tract infections. The patient age groups ranged mainly from 49--60 years. Diabetes mellitus was the most significant risk factor in these Proteus infections. [ABSTRACT FROM AUTHOR]

The article considers the development features of prototypes and virtual models of measuring instruments. The measurement errors of two DC voltmeters are investigated: a prototype on a prototyping board and its virtual model. The voltmeter prototype is implemented on the ATmega8 microcontroller with a four-bit indicator; the virtual model is developed in the Proteus environment and completely repeats the prototype schematic diagram. The GW Instek GPC power supply and the VOLTCRAFT MXD laboratory multimeter were used as reference tools for calibrating voltmeters. The absolute and relative errors of the voltmeter prototype and its virtual model in the range of 0–6 V have been assessed. It has been established that in the range of 0–1 V the high relative error of measuring voltage by the voltmeter prototype is due to the influence of the error in setting the power supply voltage, as well as deviations from the nominal values of the actual values of the circuit elements parameters. The minimum relative error of measuring voltage by the voltmeter prototype was less than 1% in the range of 5–6 V. A comparative analysis of the results of assessing the errors of the voltmeter prototype and its virtual model has been carried out and a conclusion about the comparable accuracy of the virtual model and the real prototype with equal power quality parameters has been made. The results obtained will be useful in voltage quality studies at the stages of developing prototypes and virtual models of other types of measuring instruments. [ABSTRACT FROM AUTHOR]

This study investigated the prevalence, antibiogram, virulence, extendedspectrum β-lactamases (ESBLs), and non-β-lactam encoding genes of Proteus species isolated from infected dogs in Ismailia province, Egypt. The study was conducted on 70 fecal swabs collected from dogs with diarrhea for bacteriological identification of Proteus spp. The positive isolates were evaluated for antibiotic susceptibility, molecular tests of virulence, ESBLs, and non-β-lactam encoding genes. Prevalence of Proteus spp. was 35.7% (25/70), including Proteus mirabilis (n = 23) and Proteus vulgaris (n = 2). The Proteus spp. prevalence revealed diversity, higher in males than females, in ages < 12 weeks. Investigation of antimicrobial resistance was found against penicillin and amoxicillin (100%), amoxicillin--clavulanic acid (32%), cephalosporins: cefotaxime and ceftazidime (36%), and monobactam: aztreonam (28%) as ESBLs, in addition to tetracycline (32%) and trimethoprim sulfamethoxazole (100%). The strains retrieved by PCR revealed ureC, zapA, and rsbA virulence genes with variant prevalence as 92%, 60%, and 52%, respectively. In addition, the recovered strains contained ESBL genes with a dramatic variable prevalence of 100%, 92%, 36%, and 32%, to blaTEM, blaSHV, blaCTX-M, and blaOXA-1, respectively, and non β-lactam encoding genes with a prevalence of 100%, 48%, 44%, 20%, and 12%, to sul1, tetA, intI1, qnrA, and aadA1. Moreover, 28% (7/25) of recovering strains were MDR (multidrugresistant) up to four classes of antimicrobials, and 48% (12/25) of the examined strains were MDR up to three antimicrobial classes. In conclusion, to the best of our knowledge, our study could be the first report recording MDR Proteus spp. in dogs in Egypt. [ABSTRACT FROM AUTHOR]

The paper considers the most significant relativistic effects in the rotational dynamics of Neptune's satellites (Triton (N1), Naiad (N3), Thalassa (N4), Despina (N5), Galatea (N6), Larissa (N7), and Proteus (N8)). For the first time, the most significant secular and periodic terms of the geodetic rotation of Triton and six inner satellites of Neptune are determined in the angles of their rotation relative to the fixed equator of the Earth of the J2000.0 epoch, defined in the international coordinate system (ICRF), and the vernal equinox of the J2000.0 epoch and in the Euler angles relative to their own coordinate systems. The study showed that the value of geodetic rotation can be significant not only for bodies that revolve around supermassive central bodies, but also for close satellites of giant planets. The values obtained of the geodetic rotation for the system of satellites under study can be used for a numerical study of their rotation in the relativistic approximation, and also used to estimate the influence of relativistic effects on the orbital–rotational dynamics like heavenly bodies of exoplanetary systems.

They were having features of chronic renal disease. Culture and sensitivity results were 99.8% sensitive to nitrofurantoin. And after antibiotic treatment 143 patients (95.3%) urine culture became sterile and 7 patients (4.7%) infection persisted. Conclusion: Asymptomatic bacteriuria in pregnancy is associated with maternal and fetal morbidity. It can be diagnosed by urine culture and sensitivity. Treatment with appropriate antibiotics prevent these complications. In this study prevalence of ASB in pregnant women of 6-20 weeks of gestation is around 17.8%.E. coli, Klebsilla, Proteus, Staph aureus and Streptococcus were the organisms isolated in urine culture. E. coli was identified as the commonest organism in the urine culture in all the age groups irrespective of the gestational age and socio economic status. [ABSTRACT FROM AUTHOR]

Background: Proteus syndrome is characterized by a progressive segmental or patchy growth of bone, skin, adipose tissue, and central nervous system, associated with a wide range of neoplasms, pulmonary pathology, and thrombotic risk. The main histological findings are diffuse patchy overgrowth of skin and subcutaneous tissue, plantar cerebriform connective tissue nevus, and ossification defects. Case report: We present a patient that met the clinical and histological criteria necessary for the diagnosis of the disease. He required multiple surgical interventions, including amputation of the right foot. Genetic evaluation confirmed an AKT1 mutation. Discussion: CLOVES syndrome, neurofibromatosis 1 or PTEN hamartoma tumor syndrome are partially superimposable entities to Proteus syndrome and may generate diagnostic doubt. Although the clinical criteria and histologic findings are indicative, the diagnostic confirmation of this entity is genetic. [ABSTRACT FROM AUTHOR]

Multidrug-resistant (MDR) Proteus, especially those strains producing extended-spectrum ß-lactamases (ESBL) and carbapenemases, represents a major public health concern. In the present work, we characterized 27 MDR Proteus clinical isolates, including 23 Proteus mirabilis, three Proteus terrae, and one Proteus faecis, by whole-genome analysis. Among the 27 isolates analyzed, SXT/R391 ICEs were detected in 14 strains, and the complete sequences of nine ICEs were obtained. These ICEs share a common backbone structure but also have different gene contents in hotspots and variable regions. Among them, ICEPmiChn2826, ICEPmiChn2833, ICEPmiChn3105, and ICEPmiChn3725 contain abundant antibiotic resistance genes, including the ESBL gene blaCTX-M-65. The core gene phylogenetic analysis of ICEs showed their genetic diversity, and revealed the cryptic dissemination of them in Proteus strains from food animals and humans on a China-wide scale. One of the isolates, FZP3105, acquired an NDM-1-producing MDR plasmid, designated pNDM_FZP3105, which is a self-transmissible type 1/2 hybrid IncC plasmid. Analysis of the genetic organization showed that pNDM_FZP3105 has two novel antibiotic resistance islands bearing abundant antibiotic resistance genes, among which blaNDM-1 is located in a 9.0 kb Tn125 bracketed by two copies of IS26 in the same direction. In isolates FZP2936 and FZP3115, blaKPC-2 was detected on an IncN plasmid, which is identical to the previously reported pT211 in Zhejiang province of China. Besides, a MDR genomic island PmGRI1, a variant of PmGRI1-YN9 from chicken in China, was identified on their chromosome. In conclusion, this study demonstrates abundant genetic diversity of mobile genetic elements carrying antibiotic resistance genes, especially ESBL and carbapenemase genes, in clinical Proteus isolates, and highlights that the continuous monitoring on their transmission and further evolution is needed.

The presence of acetone gas in human exhaled breath is an important test for the detection of diabetes. Much research has been focused on developing a noninvasive technique for diabetes detection. Among the various gas sensors, semiconductor metal oxide-based gas sensors have garnered research interest because of advantages such as fabrication simplicity, low cost, and low power consumption. In this work, nickel oxide (NiO) is used as the sensing material for detecting acetone. The sensitivity of NiO towards acetone gas was analyzed using COMSOL Multiphysics and the results were compared with experimental data. For an acetone concentration in the range of 5–40 ppm, the results from the simulated sensor showed good agreement with the real sensor, with some anomalies due to the practical conditions in the real chamber and the simulation tool. Comprehensive finite element analysis of the sensor was performed for different operating temperatures and gas concentrations ranging from 1 to 40 ppm in order to analyze diverse diabetes mellitus conditions. Analytical modeling was also developed to analyze the effect of the change in acetone concentration on the resistance of the sensing layer. For a user-friendly interface, a signal conditioning unit and an alarm system for diabetes detection were also built. The COMSOL Multiphysics simulation was extended using a MATLAB script to integrate the results with the signal conditioning unit in the Proteus software program. The findings also demonstrated that this approach might be used to describe and determine the performance of acetone gas sensors prior to fabrication. [ABSTRACT FROM AUTHOR]

This paper presents the real-time monitoring of energy consumption utilizing the global system for mobile communication (GSM) via wireless protocols. The power supply company has the authority to change or alter the tariff rates. The method of payment is prepaid, so there will be options for the customer to request the number of units assigned to the particular meter against the money. The customer can monitor the number of units consumed with the help of GSM. If the units are ten percent of the total units, then the system will give a warning message so that the customer can recharge it before cutting off the supply. A GSM-based wireless module has remote access to the usage of electricity. Simulation is done on Proteus while the hardware is implemented using the microcontroller Arduino Uno.

Background and Aim: Proteus bacteria, a key contributor to several gastrointestinal diseases, is known to survive in the wide pH range offered by different locations of the GI tract. The bacterial enzyme Choline TMA Lyase found in several opportunistic gut commensals catalyzes choline conversion to trimethylamine, a precursor of the pro-atherosclerotic metabolite trimethylamine N oxide. This study evaluates the pathogenic potential of Proteus gut bacteria in patients with coronary artery disease. We also sought to create a simple predictive model for assessing risk factors of coronary artery disease using a sample of Indian patients. Materials and Methods: The study included 14 patients with coronary artery disease and 6 controls. Optimal conditions were devised, and standardized protocols were followed to culture Proteus bacteria in vitro and isolate the protein of interest, Choline TMA Lyase. FTIR analysis and UV spectrophotometry were employed to quantify choline and trimethylamine N oxide levels, respectively. Finally, receiver operating characteristic analysis and multivariate logistic regression established the predictive power of the entire model and trimethylamine N oxide. Results: The findings demonstrated an optimum activity of this protein and the bacterial growth in the pH range of 7.4 - 9. Quantitative analysis showed trimethylamine N oxide levels to be significantly higher in coronary artery disease patients (1.81 μM) than in controls (0.86 μM). Conclusion: Optimum activity in the alkaline condition indicates the strong pathological potential of Proteus bacteria in the progression of coronary artery disease. The prediction model can serve as a helpful tool within the medical community to assess the risk factors for coronary artery disease. [ABSTRACT FROM AUTHOR]

Nowadays Road accident causes serious issues and many people's lives are at risk in their day-to-day life. Due to the rapid growth in science and technology, every problem which arises in today's world can be easily tackled. Road accidents are occurring at a high rate in today's world. India ranks 1st in the number of road accidents death across 199 countries followed by the U.S and China. In 2019 alone India accounts for a total of 4,49,002 road accidents reported by state union territory. Most death cases are mainly due to a lack of medical support. Even if they ended up causing accidents in remote areas, they never get medical support immediately. Due to the delay in reporting the accident, there is always some delay in ambulance arrival at the location of the accident. Thus, to prevent the delay and to get proper medical support, there must be an emergency working model which would send an exact location of the accidental zone to the nearby hospitals and police stations. With the use of modern technology, developing an automatic alert system that sends the location of the accidental zone to the nearby hospitals through GPS/GSM can be achieved and can save precious time and provide a sustainable environment where no lives can be at risk. The camera captures the accident, which can be later analyzed for investigation. The effectiveness of the proposed project is examined using PROTEUS software and simulation results are analysed.

Bacteria adapt rapidly to changes in ambient conditions, constantly inspecting their surroundings by means of their sensor systems. These systems are often thought to respond only to signals of a chemical nature. Yet, bacteria are often affected by mechanical forces, e.g., during transition from planktonic to sessile state. Mechanical stimuli, however, have seldom been considered as the signals bacteria can sense and respond to. Nonetheless, bacteria perceive mechanical stimuli, generate signals, and develop responses. This review analyzes the information on the way bacteria respond to mechanical stimuli and outlines how bacteria convert incoming signals into appropriate responses. [ABSTRACT FROM AUTHOR]

Klebsiella spp. and Proteus spp. cause hospital-acquired urinary tract infections (UTIs), which are often related to the use of catheters. To create a vaccine preventing UTI, immunogenic bacterial antigens with common epitopes are still being looked for. In this work, the role of polysaccharide antigens of four Klebsiella spp. and eight Proteus spp. strains in serological cross-reactions with specific antisera was examined. Enzyme-linked immunosorbent assay (ELISA), Western blotting, and silver staining by Tsai method were performed. The Klebsiella and Proteus spp. LPSs and cells were used as antigens. Polyclonal rabbit sera specific to Klebsiella oxytoca 0.023 and 0.062 strains and four Klebsiella spp. LPSs were obtained. The ELISA and Western blotting results showed the strongest cross-reactions occurring between lipopolysaccharides (LPSs) from four Klebsiella strains and P. vulgaris O42 antiserum. The silver-staining procedure revealed the patterns typical of both slow- and fast-migrating mass species of the Klebsiella LPSs. The Klebsiella spp. antigens also cross-reacted with four P. penneri antisera, and most of the reactions were observed as low-migrating patterns. From two K. oxytoca antisera obtained in this work, only one, the K. oxytoca 0.062 antiserum, cross-reacted with satisfactory strength with P. penneri LPSs (19, 22, and 60). Obtaining cross-reactions between the antigens of Klebsiella strains and Proteus antisera and in the opposite systems is important for proving the immunogenic role of polysaccharide antigens in triggering the immunological response.

Regulating the output voltage based on the desired set point is useful for many applications. However, getting the optimal value using fast computation with minimal error is still challenging. This paper aims to design, simulate, and implement a secondorder Buck-Boost DC-DC converter circuit so that the voltage result according to the desired set point can be achieved. Initially, testing is conducted using Matlab Simulink. Then, Proteus is used to test the computation of the program on embedded systems in which the result is implemented in C. In low voltage power electronics applications, this approach has never been used to determine the output form. To determine the value of Kp, Ki, dan Kd, PID, Ziger Nichos (Guo, 2002). method is used. Meanwhile, tuning is done through Matlab. For simulation on Proteus, the output is tested by setting the setpoint values of 3.0, 2.5, and 1.7 volts. This aims to see the pattern of changes in the simulation. The simulation results with Proteus show that they have similar peak values but with different overshoot values. This is because the simulation must pass the reference voltage before it drops to the desired setpoint value. Proteus simulation can also help to prove embedded system programs are running correctly. On the other hand, the value of 1.7 volts is used as a setpoint in device implementation. This is due to the determination that the setpoint voltage in the implementation does not exceed the value of the source/power supply. The results show that for the rise time value of 378,770 ms, Overshoot and settling time are 11.798% and 0, respectively. This means the result produces an optimal value which is a return to the initial target. The optimal factor is assessed from the ability to minimize existing errors as well as having the shortest possible computational process. [ABSTRACT FROM AUTHOR]

Many reports have defined oxidative stress as an imbalance between an enhanced reactive oxygen/nitrogen species and the lack of protective ability in antioxidants. From that point of view, free radical-induced damage caused by oxidative stress seems to be a probable contributing factor to the pathogenesis of many newborn diseases, such as respiratory distress syndrome, bronchopulmonary dysplasia, periventricular leukomalacia, necrotizing enterocolitis, patent ductus arteriosus, and retinopathy of prematurity. This study was conducted on a sample of (30) players. researchers used the experimental approach (equivalent groups for its suitability and method of study. the sample was divided into two groups, (15) players representing the control group and (15) players representing the experimental group. the study aims to identify the effect of antioxidants on oxygenated blood pressure and free radicals for athletes. the study showed that there is an effect of antioxidants (vitamins on increasing the activity of the enzyme (SGOT) involved in ATP rebuilding processes, and an effect of antioxidants on reducing oxygen blood pressure while not the effect of antioxidants on SGPT enzyme activity is clear, which shows that it is not involved in reducing free radical, muscle fatigue and blood pressure. Hence, the researchers came out with a set of recommendations, including the need to pay attention to taking vitamins because of their role in reducing the effects of free radicals and emphasizing the gradual increase in training loads.

To gain a general understanding of the SOS system in Proteus species, in this study LexA-binding sites and the LexA regulons in 23 Proteus genomes were first predicted by phylogenetic footprinting server, then with Proteus vulgaris as an example, the expression of LexA regulon in iron limitation was investigated by proteomic analysis and quantitative reverse transcription polymerase chain reaction (RT-qPCR) method. The results showed that LexA proteins were highly conserved in Proteus species, and were in a close phylogenetic relationship with those in Gram-negative bacteria; the core SOS response genes lexA and recA were found in all the 23 genomes, indicating that this system was widely distributed in this genus; besides that, putative LexA-binding sites were also found in the upstream sequences of some genes involved in other biological processes such as biosynthesis, drug resistance, and stress response. Proteomic and RT-qPCR analyses showed that under iron deficient condition, the expression of lexA, recA and sulA was transcriptionally upregulated (p < 0.05), lexA was also translationally upregulated but recA was on the contrary (p < 0.05), whereas another SOS response gene dinI was transcriptionally downregulated (p < 0.01). These results indicated that in response to iron deficiency, the members of LexA regulon were not regulated by the same way, suggesting the existence of a precise regulation mechanism of SOS response in P. vulgaris. In conclusion, this study provided a preliminary understanding of the SOS system in Proteus species, which laid the foundation for further investigation of its roles in SOS response and other biological processes.

The Gram-negative bacterium Proteus mirabilis causes a large proportion of catheter-associated urinary tract infections, which are among the world's most common nosocomial infections. Here, we characterize P. mirabilis bacteriophage Privateer, a prolate podophage of the C3 morphotype isolated from Texas wastewater treatment plant activated sludge. Basic characterization assays demonstrated Privateer has a latent period of ~40 min and average burst size around 140. In the 90.7 kb Privateer genome, 43 functions were assigned for the 144 predicted protein-coding genes. Genes encoding DNA replication proteins, DNA modification proteins, four tRNAs, lysis proteins, and structural proteins were identified. Cesium-gradient purified Privateer particles analyzed via LC-MS/MS verified the presence of several predicted structural proteins, including a longer, minor capsid protein apparently produced by translational frameshift. Comparative analysis demonstrated Privateer shares 83% nucleotide similarity with Cronobacter phage vB_CsaP_009, but low nucleotide similarity with other known phages. Predicted structural proteins in Privateer appear to have evolutionary relationships with other prolate podophages, in particular the Kuraviruses. [ABSTRACT FROM AUTHOR]

Background: Osteoarticular infections in adults and children are a significant cause of elevated morbidity and may lead to restrictive mobility of various stages. Objective: Isolation and determination of the occurrence, pathomorphological and antibiotic susceptibility patterns of isolated microorganisms from the patients with osteoarticular infections. Methods: This research work was carried out at the Institute of Molecular Biology and Biotechnology (IMBB), The University of Lahore (UOL). Pus specimens (n = 120) were gathered from patients of osteoarticular infections. Bacterial isolates were purified and identified biochemically. Antibiotic resistance of the bacterial isolates was investigated by the criterion set by Clinical and Laboratory Standards Institute (CLSI). All experiments were run in triplicate using randomized study design. The mean, standard error and standard deviation values were determined using SPSS (v. 23.0). Results: Out of 120 samples, 111 isolated samples (93%) were tested positive for total viable count. The isolated bacterial species were observed to be Streptococcus pyogenes, Staphylococcus hemolyticus, S. aureus, Pseudomonas aeruginosa, Escherichia coli, Micrococcus sp., Serratia sp., Klebsiella sp., Enterobacter sp., and Proteus sp. Antibiogram results also yielded S. pyogenes and S. hemolyticus to be erythromycin resistant, while S. aureus was vancomycin resistant. E. coli and Klebsiella sp. were found to be resistant to tobramycin while Proteus and Enterobacter sp. were both sensitive to it. Conclusion: P. aeruginosa, E. coli, and S. aureus were prevalent in all groups of age, while Micrococcus and Serratia sp. were common in 16-55 years. Patient hygiene, immune health and the course of medications are all factors that should be kept in consideration while treating the disease. [ABSTRACT FROM AUTHOR]

The public lighting system was being a vital part all over the world for many years. Indeed, as the number of population and urbanism grow, this system is becoming a primordial part of our life comfort. Therefore, it is used extensively leading to an increased important amount of electrical energy being consumed. This paper proposes an idea of an intelligent energy management system (EMS) for public lightening system consumption based on an autonomous hybrid sources of electrical energy. It is composed of a PV system installed at the top of the lightening system and a battery storage system, where an intelligent energy management system is used to ensure the charging of the battery during the daylight with the option of supporting the PV system production in case of low period irradiation during the day. Whereas, during the night, the battery fully powers the lightening system. In the same for the protection of the battery system and its related lifespan, the proposed (EMS) takes into accounts this issue. Furthermore, this system has the ability of recognizing accurately the basic data on the length of the day, the sunrise time and sunset time automatically based on the location of the used public lightening system which is defined by its longitude and latitude. The proposed EMS is built around a special electronics card including display screen of main information with the insertion of special sensors such as current and voltage sensors, which were built by the authors. The proposed system has been tested in a known location where the obtained results prove the validity of the proposed management system for ensuring the operation of the public lightening system.

Proteus spp. are members of the Enterobacteriaceae family and are Gram-negative, rod-shaped bacteria known to mainly cause urinary tract infections (UTIs) in humans. However, even though scarce evidence exists suggesting their potential to cause infective endocarditis (IE), a study summarizing the existing evidence is lacking. The purpose of this study was to systemically review all published cases of IE by Proteus species in the literature. A systematic review of PubMed, Scopus and Cochrane Library (through 5th May 2020) for studies providing epidemiological, clinical and microbiological data as well as data on treatment and outcomes of IE by Proteus species was performed. A total of 16 studies, containing data of 16 patients, were included. A prosthetic valve was present in 25%, while the most common causative pathogen was P. mirabilis. Aortic valve was the most common infected site in 33.3%, followed by mitral valve in 26.7%. Diagnosis was set with transesophageal echocardiography in 37.5%, and transthoracic echocardiography in 25%, while the diagnosis was set at autopsy in 25%. Fever and sepsis were present in 100% and 84.6%, respectively. Aminoglycosides and cephalosporins were the most common antimicrobials used for treatment. Clinical cure was noted in 62.5%, while overall mortality was 43.8%. This systematic review describes IE by Proteus species in detail and provides information on epidemiology, clinical presentation, treatment and outcomes. [ABSTRACT FROM AUTHOR]
