Evaluation of Representative Microbiological Sampling Sites of Goat and Sheep Dressed Carcasses

Statistical analysis of data of number of sampling points for microbial counts representing the entire goat/sheep carcass was carried out. Thirtytwo sampling points were evaluated out of which fourteen were found to represent the entire dressed carcass for assessing its hygienic efficacy

Bacteriological Status Of Meat During Various Stages Of Processing In AFD Packing Plant

Studies on eight carcasses(sheep/goat) for microbial status of meat at different stages of processing viz dressed carcass before after chilling, after boning, cocking, cooking, cooling, slicing, deep freezing, freeze drying, and packing have been carried out. No difference in microbial status has been observed in sheep and goat carcass. The lower (front body) portion of carcass has higher microbial load than the upper portion (hind body). No significant increase in total colony counts was observed on keeping the carcass for 24 hours at 5 degree centigrade. The highest microbial load has been observed on boned meat. The total colony counts (TCC) gets reduced during the process of deep freezing and freeze drying. The precooked, freeze dried meat has TCC up to 266

School environment assessment tools to address behavioural risk factors of non-communicable diseases: A scoping review

We aimed to identify, describe and analyse school environment assessment (SEA) tools that address behavioural risk factors (unhealthy diet, physical inactivity, tobacco and alcohol consumption) for non-communicable diseases (NCD). We searched in MEDLINE and Web of Science, hand-searched reference lists and contacted experts. Basic characteristics, measures assessed and measurement properties (validity, reliability, usability) of identified tools were extracted. We narratively synthesized the data and used content analysis to develop a list of measures used in the SEA tools. Twenty-four SEA tools were identified, mostly from developed countries. Out of these, 15 were questionnaire based, 8 were checklists or observation based tools and one tool used a combined checklist/observation based and telephonic questionnaire approach. Only 1 SEA tool had components related to all the four NCD risk factors, 2 SEA tools has assessed three NCD risk factors (diet/nutrition, physical activity, tobacco), 10 SEA tools has assessed two NCD risk factors (diet/nutrition and physical activity) and 11 SEA tools has assessed only one of the NCD risk factor. Several measures were used in the tools to assess the four NCD risk factors, but tobacco and alcohol was sparingly included. Measurement properties were reported for 14 tools. The review provides a comprehensive list of measures used in SEA tools which could be a valuable resource to guide future development of such tools. A valid and reliable SEA tool which could simultaneously evaluate all NCD risk factors, that has been tested in different settings with varying resource availability is needed

Epitope-Based Immunoinformatics and Molecular Docking Studies of Nucleocapsid Protein and Ovarian Tumor Domain of Crimean–Congo Hemorrhagic Fever Virus

Crimean–Congo hemorrhagic fever virus (CCHFV), the fatal human pathogen is transmitted to humans by tick bite, or exposure to infected blood or tissues of infected livestock. The CCHFV genome consists of three RNA segments namely, S, M, and L. The unusual large viral L protein has an ovarian tumor (OTU) protease domain located in the N terminus. It is likely that the protein may be autoproteolytically cleaved to generate the active virus L polymerase with additional functions. Identification of the epitope regions of the virus is important for the diagnosis, phylogeny studies, and drug discovery. Early diagnosis and treatment of CCHF infection is critical to the survival of patients and the control of the disease. In this study, we undertook different in silico approaches using molecular docking and immunoinformatics tools to predict epitopes which can be helpful for vaccine designing. Small molecule ligands against OTU domain and protein–protein interaction between a viral and a host protein have been studied using docking tools

Guidelines to bridge the gap between adaptive thermal comfort theory and building design and operation practice

Adaptive thermal comfort guidelines have been developed within the work of Annex 69: “Strategy and practice of adaptive thermal comfort in low energy buildings”. The guidelines have been established based on a framework for adopting adaptive thermal comfort principles in building design and operation developed by the authors. The guidelines target building practitioners, addressing the critical interrelated role building planners, building operators and occupants play. A successful adaptive thermal comfort design, in which design for human thermal adaptation is foreseen, planned, and carefully embedded in the design and operation intent, is based on broad knowledge and understanding of the multiple quantifiable and non-quantifiable factors influencing human perception, as well as human building interaction. Adaptive building design follows a user-centric integrated design approach and therefore it is critical to consider the occupants’ and the operators’ role in buildings already in the design phase. This paper focuses on three main challenges identified earlier and how these are addressed in the guidelines, i.e. i) updating prevailing knowledge about human thermophysiology and adaptation, ii) developing a procedure for design of adaptive opportunities, and iii) providing guidance for operational planning and operation of adaptive buildings. The challenge for future research remains to assess the magnitude of how specific design decisions affect particular adaptive mechanisms

Synthesis and characterization of ionic block copolymer templated calcium phosphate nanocomposites

Self-assembling thermo-reversibly gelling anionic and zwitterionic pentablock copolymers were used as templates for precipitation of calcium phosphate nanostructures, controlling their size and ordered structural arrangement. Calcium and phosphate ions were dissolved in a block-copolymer micellar dispersion at low temperatures. Aging at ambient temperature produced inorganic nanoparticles, presumably nucleated by ionic interactions. The self-assembled nanocomposites were characterized by small-angle X-ray and neutron scattering (SAXS/SANS), nuclear magnetic resonance (NMR), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM). 1H-31P NMR with 1H spin diffusion from polymer to phosphate proved the formation of nanocomposites, with inorganic particle sizes from ∼2 nm, characterized by 1H-31P dipolar couplings, to \u3e 100 nm. TEM analysis showed polymer micelles surrounded by calcium phosphate. SAXS attested that a significant fraction of the calcium phosphate was templated by the polymer micelles. SANS data indicated that the order of the polymer was enhanced by the inorganic phase. The nanocomposite gels exhibited higher moduli than the neat polymer gels. The calcium phosphate was characterized by TGA, X-ray diffraction, high-resolution TEM, and various NMR techniques. An unusual crystalline phase with \u3e2 chemically and \u3e3 magnetically inequivalent HPO4 2- ions was observed with the zwitterionic copolymer, highlighting the influence of the polymer on the calcium phosphate crystallization. The inorganic fraction of the nanocomposite was around 30 wt % of the dried hydrogel. Thus, a significant fraction of calcium phosphate has been templated by the tailored self-assembling ionic block copolymers, providing a bottom-up approach to nanocomposite synthesis

Preferences and skills of Indian public sector teachers

With a sample of 700 future public sector primary teachers in India, a Discrete Choice Experiment is used to measure job preferences, particularly regarding location. General skills are also tested. Urban origin teachers and women are more averse to remote locations than rural origin teachers and men respectively. Women would require a 26-73 percent increase in salary for moving to a remote location. The results suggest that existing caste and gender quotas can be detrimental for hiring skilled teachers willing to work in remote locations. The most preferred location is home, which supports decentralised hiring, although this could compromise skills

Utility of first trimester ultrasound before 12 weeks of gestation at tertiary care centre in western India

Background: The first trimester begins on the first day of the last menstrual period (LMP) and lasts until the end of 12 weeks of gestation. Transvaginal ultrasound is modality of choice for establishing the presence of an intrauterine pregnancy in the first trimester. The focus of our study is routine early pregnancy ultrasound. The purpose of this study was to diagnose various conditions of pregnancy at an early stage by using ultrasound.Methods: We conducted retrospective data analysis of random 250 pregnant patients who had undergone first-trimester ultrasonography USG) (transvaginal/abdominal) in their first antenatal visit at S.V.P. Hospital, Ahmedabad, Gujarat, India from March 2021 to February 2022. The patient was selected by a simple randomized method. Maternal age, parity, gestational age, and special features regarding maternal gestational history were compared with USG findings. Patients were divided into 13 groups on the basis of ultrasonographic diagnosis.Results: We noted 76.8% of patients had single, viable, intrauterine pregnancies, while 23.2% had complicated pregnancies with uterine anomalies, ovarian cysts, leiomyoma, caesarean scar pregnancy or subchorionic hematomas.Conclusions: Ultrasound measurement of fetus in first trimester is most accurate method to confirm gestational age. It is less expensive and easily available modality. First-trimester ultrasound is useful to define embryonic landmarks in developmental stages with reference to gestational age, early diagnosis of miscarriage, ectopic pregnancy, molar pregnancy, multifetal pregnancy, major fetal malformation. And also, to diagnose pregnancy with leiomyoma, caesarean scar pregnancy, uterine anomaly and pre-eclampsia with the help of uterine artery PI
