Techno-Economic Aspects of Solid Food Wastes into Bio-Manure
Solid waste is health hazard and cause damage to the environment due to improper handling. Solid waste comprises of Industrial Waste (IW), Hazardous Waste (HW), Municipal Solid Waste (MSW), Electronic waste (E-waste), Bio-Medical Waste (BMW) which depend on their supply & characteristics. Food waste or Bio-waste composting and its role in sustainable development is explained in food waste is a growing area of concern with many costs to our community in terms of waste collection, disposal and greenhouse gases. When rotting food ends up in landfill it turns into methane, a greenhouse gas that is particularly damaging to the environment. Composting is biochemical process in which organic materials are biologically degraded, resulting in the production of organic by products and energy in the form of heat. Heat is trapped within the composting mass, leading to the phenomenon of self-heating.This overall process provide us Bio-Manure.

Effectiveness of a national quality improvement programme to improve survival after emergency abdominal surgery (EPOCH): a stepped-wedge cluster-randomised trial
Background: Emergency abdominal surgery is associated with poor patient outcomes. We studied the effectiveness of a national quality improvement (QI) programme to implement a care pathway to improve survival for these patients. Methods: We did a stepped-wedge cluster-randomised trial of patients aged 40 years or older undergoing emergency open major abdominal surgery. Eligible UK National Health Service (NHS) hospitals (those that had an emergency general surgical service, a substantial volume of emergency abdominal surgery cases, and contributed data to the National Emergency Laparotomy Audit) were organised into 15 geographical clusters and commenced the QI programme in a random order, based on a computer-generated random sequence, over an 85-week period with one geographical cluster commencing the intervention every 5 weeks from the second to the 16th time period. Patients were masked to the study group, but it was not possible to mask hospital staff or investigators. The primary outcome measure was mortality within 90 days of surgery. Analyses were done on an intention-to-treat basis. This study is registered with the ISRCTN registry, number ISRCTN80682973. Findings: Treatment took place between March 3, 2014, and Oct 19, 2015. 22 754 patients were assessed for elegibility. Of 15 873 eligible patients from 93 NHS hospitals, primary outcome data were analysed for 8482 patients in the usual care group and 7374 in the QI group. Eight patients in the usual care group and nine patients in the QI group were not included in the analysis because of missing primary outcome data. The primary outcome of 90-day mortality occurred in 1210 (16%) patients in the QI group compared with 1393 (16%) patients in the usual care group (HR 1·11, 0·96–1·28). Interpretation: No survival benefit was observed from this QI programme to implement a care pathway for patients undergoing emergency abdominal surgery. Future QI programmes should ensure that teams have both the time and resources needed to improve patient care.

Host Lipid Rafts Play a Major Role in Binding and Endocytosis of Influenza A Virus
Influenza still remains one of the most challenging diseases, posing a significant threat to public health. Host lipid rafts play a critical role in influenza A virus (IAV) assembly and budding, however, their role in polyvalent IAV host binding and endocytosis had remained elusive until now. In the present study, we observed co-localization of IAV with a lipid raft marker ganglioside, GM1, on the host surface. Further, we isolated the lipid raft micro-domains from IAV infected cells and detected IAV protein in the raft fraction. Finally, raft disruption using Methyl-β-Cyclodextrin revealed significant reduction in IAV host binding, suggesting utilization of host rafts for polyvalent binding on the host cell surface. In addition to this, cyclodextrin mediated inhibition of raft-dependent endocytosis showed significantly reduced IAV internalization. Interestingly, exposure of cells to cyclodextrin two hours post-IAV binding showed no such reduction in IAV entry, indicating use of raft-dependent endocytosis for host entry. In summary, this study demonstrates that host lipid rafts are selected by IAV as a host attachment factors for multivalent binding, and IAV utilizes these micro-domains to exploit raft-dependent endocytosis for host internalization, a virus entry route previously unknown for IAV
Effect of oral contraceptives on visual evoked potentials in premenopausal females
Introduction: The sex hormones are not only restricted to the influence the reproductive organs and processes in the female body, but also have great effect on the functioning of the nervous system. Evoked potentials are one of the many electrophysiological parameters, used to assess the neuronal functioning. The aim of this prospective study was to analyze the effects of oral contraceptive pills on the visual evoked potentials in premenopausal females.
Methods: The VEP was measured in 76 females during follicular and luteal phases of their menstrual cycle, and latencies of the three waveforms N70, P100 and N135 were measured. All the subjects were prescribed oral contraceptive pills containing 0.03 mg estradiol and 0.15 levonorgestrel. The VEP latencies were measured again after 4 months of oral contraceptive intake.
Result: The result showed an increase in all the three latencies of VEP waveforms due to oral contraceptive intake. Although the increase in latencies were not significant (P>0.05).
Conclusion: Hence it was concluded that VEP seems to be influenced by the female steroid hormones during the menstrual cycle and also due to oral intake in the form of contraceptives
STUDY TO KNOW THE EFFECT OF PHOTOTHERAPY ON SERUM CALCIUM LEVEL IN NEONATAL HYPERBILIRUBINEMIA
Background: Phototherapy is the most common method to treat neonatal jaundice. The effect of phototherapy on serum calcium levels is a questionable issue.
Objective: To study to know the effect of phototherapy on serum calcium level in neonatal hyperbilirubinemia.
Methods: Cohort study compared total serum calcium level before and after phototherapy in neonates with hyperbilirubinemia. Study was conducted on 54 neonates with high total serum bilirubin levels, according to the Bhutani curve and was treated with phototherapy at neonatal intensive care unit in the Department of Pediatrics at Mayo Institute of Medical Sciences from November 2021 to April 2022.
Results: Hypocalcaemia was observed in 33.33% of neonates after phototherapy. The difference between pre- and post-phototherapy serum calcium levels was found to be statistically significant (p<0.005).
Conclusion: Hypokalcemia has a significant association with phototherapy
Enhancement in the magnetic, optical and electrical properties of Ti0.9Co0.03O2 and Ti0.97Fe0.03O2 nanoparticles with Ce co-doping
Ti0.97Co0.03O2 (TC3), Ti0.93Co0.03Ce0.04O2 (TCC34), Ti0.97Fe0.03O2 (TF3) and Ti0.93Fe0.03Ce0.04O2 (TFC34) nanoparticles were prepared by a chemical route. The x-ray diffraction pattern shows the coexistence of anatase and rutile phases and the value of the average particle size is measured using the Scherrer relation. The images from transmission electron microscopy show that the average particle size is 24, 27, 28 and 30 nm, respectively, for TC3, TCC34, TF3 and TFC34 and they are also represented by a particle distribution histogram. Fourier transform infrared spectroscopy has been used to confirm the stretching of Ce with the Co-O-Ti and Fe-O-Ti bond. Magnetic measurements detect ferromagnetism in all samples with the saturation magnetization increasing abruptly with Ce co-doping. All the samples show large photocatalytic activity and co-doping of Ce exhibits large-scale photocatalytic activity, and the value of the resulting band gap is calculated. This effect is due to the insertion of Ce3+/4+ in the TiO2 matrix, which generates an n-type impurity band. The dielectric behaviour is explained by the interface polarization, the decreasing trend of dielectric permittivity with increasing frequency by a Maxwell-Wagner and Koops' theory and is constant up to higher frequency regions due to the nano size effect. The dielectric behaviour is also explained by measuring frequency dependent ac conductivity
Effects of health behaviour change intervention through women\u27s self-help groups on maternal and newborn health practices and related inequalities in rural India: A quasi-experimental study
Background: Despite the health system efforts, health disparities exist across sub-populations in India. We assessed the effects of health behaviour change interventions through women\u27s self-help groups (SHGs) on maternal and newborn health (MNH) behaviours and socio-economic inequalities. Methods: We did a quasi-experimental study of a large-scale SHG program in Uttar Pradesh, India, where 120 geographic blocks received, and 83 blocks did not receive health intervention. Data comes from two cross-sectional surveys with 4,615 recently delivered women in 2015, and 4,250 women in 2017. The intervention included MNH discussions in SHG meetings and community outreach activities. The outcomes included antenatal, natal and postnatal care, contraceptive use, cord care, skin-to-skin care, and breastfeeding practices. Effects were assessed using multilevel mixed-effects regression adjusted difference-in-differences (DID) analysis adjusting for geographic clustering and potential covariates, for all, most-marginalised and least-marginalised women. Concentration indices examined the socio-economic inequality in health practices over time. Findings: The net improvements (5–11 percentage points [pp]) in correct MNH practices were significant in the intervention areas. The improvements over time were higher among the most-marginalised than least-marginalised for antenatal check-ups (DID: 20pp, p \u3c 0•001 versus DID: 6pp, p = 0•093), consumption of iron folic acid tablets for 100 days (DID: 7pp, p = 0•036 versus DID: -1pp, p = 0•671), current use of contraception (DID: 12pp, p = 0•046 versus DID: 10pp, p = 0•021), cord care (DID: 12pp, p = 0•051 versus DID: 7pp, p = 0•210), and timely initiation of breastfeeding (DID: 29pp, p = 0•001 versus DID: 1pp, p = 0•933). Lorenz curves and concentration indices indicated reduction in rich-poor gap in health practices over time in the intervention areas. Interpretation: Disparities in MNH behaviours declined with the efforts by SHGs through behaviour change communication intervention
