Abstract	The research conducts a life cycle assessment (LCA) on wastewater treatment (WWT) methods-membrane bioreactor (MBR), soil biotechnology (SBT), and bio-electrochemical constructed wetlands (BCW)-in comparison with the conventional activated sludge process (ASP). Employing SimaPro v9.5 with a cradle-to-gate system boundary, the analysis utilizes the IMPACT 2002 + method, employing per cubic meter of treated wastewater as the functional unit. The analysis shows that SBT exhibits the lowest environmental impacts among the considered WWT methods. The global warming potential was 0.0996 kg CO

Abstract	Introduction: Thyroid-releasing hormones are pivotal in regulating cardiovascular (CVS) function and maintaining its hemodynamics and homeostasis. Even a minor alteration in thyroid function has an enormous implication on CVS morbidity and mortality. Moreover, hypothyroidism was found to be a potential menace for coronary artery disease (CAD). The objective of this study was to determine the role of thyroid-releasing hormones in patients suffering from acute coronary syndrome (ACS). Methodology: Among a cohort of 100 patients suffering with ACS, a complete history and clinical information followed by physical examination and electrocardiography were recorded. Blood samples were also collected to record the blood sugar levels i.e., fasting blood sugar (FBS), postprandial blood sugar (PPBS), and thyroid profile, including free thyroid stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), and reverse triiodothyronine (rT3). The data was analyzed using SPSS version 26 software (IBM Corp., Armonk, NY, USA). Result: The study identified alterations in the thyroid hormone levels in 27% of patients suffering from ACS. The prevalence of euthyroid sick syndrome was found to be 59.3%, while subclinical hypothyroidism and subclinical hyperthyroidism were reported among 18.5% and 14.8% of patients respectively. There was no significant difference found between males and females. The study illustrated a greater occurrence of aberrant thyroid hormone profiles among those aged 40-60 years. The ST-elevated myocardial infarction (STEMI) group had a statistically significant higher prevalence of an aberrant thyroid hormone profile compared to the non-ST-elevated myocardial infarction (NSTEMI) and unstable angina (UA) groups (p=0.02). A total of nine patients died with ACS and all of those had statistically significant low fT3 and TSH values while higher rT3 values (p<0.05). Conclusion: An atypical thyroid status has been found to elevate the likelihood of developing CAD and experiencing CVS mortality. This condition can impact ventricular function and serum cholesterol levels as well as heart rate and rhythm. Therefore, understanding this relationship could potentially lead to improved treatment strategies for individuals with ACS which will further prevent major CVS complications.

Abstract	In this study, bamboo polymer composite (BPC) was prepared by blending of high-density polyethylene (HDPE) with boric acid - borax (Ba-Bx) pre-treated bamboo fibers as reinforcement material and by using maleic anhydride grafted polyethylene as coupling agent. BPCs were incorporated with conventional flame retardants (FRs) additives such as ammonium polyphosphate (APP) along with nano particles such as silicon dioxide (nano-SiO₂) and flame performance was investigated using cone calorimeter and limiting oxygen index analysis (LOI). The thermal behaviour of BPC was investigated under nitrogen atmosphere using thermogravimetric analyser (TGA). The maximum improvement in flammability was achieved with flame additive i.e., Ba-Bx 5%/APP15%. LOI value was found to be highest at Ba-Bx 5%/APP 13%/nano-SiO₂ 2%. Mechanical properties of BPCs were analysed using flexural and tensile tests. While the flame and thermal properties of BPCs was improved significantly, the strength properties were marginally reduced due to application of FR additives. In general, APP as synergist with Ba-Bx improved thermal stability and flammability of BPCs.

Abstract	Congenital lobar emphysema (CLE) is a rare developmental malformation that presents as neonatal respiratory distress and can be successfully managed with prompt intervention. Hyperinflation of the affected lobe with mediastinal shift is the characteristic radiological finding. However, the etiology mostly remains unknown. Here, we report a case of CLE that microscopically revealed bronchial cartilaginous hypoplasia as an underlying cause of this malformation.

Abstract	Introduction: Type 1 diabetes mellitus (T1DM) is associated with other autoimmune disorders that are characterized by presence of organ-specific autoantibodies. The present study was undertaken to assess the prevalence of organ-specific autoantibodies among newly diagnosed T1DM subjects of India and to study its relationship with glutamic acid decarboxylase antibody (GADA). We also compared the clinical and biochemical parameters in GADA-positive and -negative T1DM subjects. Methods: In a hospital-based cross-sectional study, we studied 61 patients with newly diagnosed T1DM ≤ 30 years of age. T1DM was diagnosed on the basis of acute onset of osmotic symptoms with or without ketoacidosis, severe hyperglycaemia [blood glucose > 13.9 mmol/l (>250 mg/dl)] and insulin requirement from the onset of diabetes. Subjects were screened for autoimmune thyroid disease (thyroid peroxidase antibody [TPOAb]), celiac disease (tissue transglutaminase antibody [tTGAb]), and gastric autoimmunity (parietal cell antibody [PCA]). Results: Of the 61 subjects, more than one-third (38%) had at least one positive organ-specific autoantibody. In particular, 13 (21.3%) were found to be positive for TPOAb, nine (14.8%) were positive for tTGAb and 11 (18%) were positive for PCA. GADA was positive in 15 (25%) subjects. The frequency of TPOAb tended to be higher in patients who had GADA positivity compared with those with no circulating GADA (40% Conclusion: We support the recommendation for regular screening of organ-specific autoantibodies, in particular TPOAb, tTGAb and PCA in all patients with T1DM. Detection of these autoantibodies at onset may prevent complications associated with delayed diagnosis of these disorders. We also conclude that there is higher frequency of TPOAb and PCA in GADA-positive T1DM patients as compared to negative ones. However, patients with positive GADA had similar clinical and biochemical parameters compared to GADA-negative subjects. Lastly, low GADA positivity in our study cohort as compared to Western populations suggests the heterogenous nature of T1DM in the Indian population.

Abstract	Background and aims: We aim to compare the various risk factors for erectile dysfunction (ED) in type 2 diabetes mellitus (DM) and nondiabetic patients. Materials and methods: We retrospectively collected and evaluated the data of 175 OPD patients with ED. We included 138 patients of ED from endocrinology and urology OPD after exclusion. ED was assessed by using a questionnaire adapted from the abridged five-item version of the International Index of Erectile Function (IIEF-5) score. Results: A total of 96 (69.56%) were diabetic, and 42 (30.43%) were nondiabetic. The majority of patients (62.31 %) were in the age group of 40-60 years. Thirty-nine (28.26%) were alcoholics, and 55 (40%) were smokers. The average duration of diabetes was 6.6±1.5 years. Hypertension was present in 49 (35.5%). Diabetic patients were significantly older (47.9±8.2 vs. 40.2±7.6 years, p=0.0001) and obese (BMI (kg/m Conclusions: The IIEF-5 score was lower in diabetic cases as compared to those without diabetes. The factors that significantly contributed to ED in type 2 DM patients, as compared to nondiabetic patients, were age, BMI, waist circumference, hypertension, poor glycemic control, LH, and testosterone levels.

Abstract	The extensive use of petroleum-based non-biodegradable plastics for various applications has led to global concerns regarding the severe environmental issues associated with them. However, biodegradable plastics are emerging as green alternatives to petroleum-based non-biodegradable plastics. Biodegradable plastics, which include bio-based and petroleum-based biodegradable polymers, exhibit advantageous properties such as renewability, biocompatibility, and non-toxicity. Furthermore, certain biodegradable plastics are compatible with existing recycling streams intended for conventional plastics and are biodegradable in controlled and/or predicted environments. Recycling biodegradable plastics before their end-of-life (EOL) degradation further enhances their sustainability and reduces their carbon footprint. Since the production of biodegradable plastic is increasing and these materials will coexist with conventional plastics for many years to come, it is essential to identify the optimal recycling options for each of the most prevalent biodegradable plastics. The substitution of virgin biodegradable plastics by their recyclates leads to higher savings in the primary energy demand and reduces global warming impact. This review covers the current state of the mechanical, chemical, and bio-recycling of post-industrial and post-consumer waste of biodegradable plastics and their related composites. The effects of recycling on the chemical structure and thermomechanical properties of biodegradable plastics are also reported. Additionally, the improvement of biodegradable plastics by blending them with other polymers and nanoparticles is comprehensively discussed. Finally, the status of bioplastic usage, life cycle assessment, EOL management, bioplastic market, and the challenges associated with the recyclability of biodegradable plastics are addressed. This review gives comprehensive insights into the recycling processes that may be employed for the recycling of biodegradable plastics.

Abstract	The majority of households in rural India use cow dung and crop residue for cooking, which contributes to both indoor and outdoor air pollution. After being used for cooking and other agricultural purposes, surplus crop residue left uncollected and burned openly accountable for notorious air pollution episodes in India. Air pollution and clean energy are critical challenges in India. Utilizing locally available biomass waste can be a sustainable solution to reducing air pollution and energy poverty. However, formulating any such policy and its practical implementation requires a clear understanding of currently available resources. The current study presents the first district-scale analysis of the cooking energy potential of locally available biomass (livestock and crop waste) if converted to energy by anaerobic digestion processes for 602 rural districts. The analysis indicates that rural India needs 1927TJ/day (2.75 MJ/capita-day) energy to meet the cooking energy demand. Utilizing locally available livestock waste can generate 715 TJ/day (1.02 MJ/capita-day) of energy, equivalent to 37 % of the demand. Only 2.15 % of districts have 100 % potential for cooking energy demand by utilizing locally produced livestock waste. Using surplus crop residue for energy can provide 2296 TJ/day(3.27 MJ/capita-day) of energy. If locally utilized, surplus residue can meet 100 % of energy demand in 39 % of districts. Combining livestock waste and surplus residue can produce 3011 TJ/day(4.29 MJ/capita-day) of energy, fulfilling >100 % of energy demand in 55.6 % of rural districts. Furthermore, converting agricultural waste into clean energy has the potential to reduce PM2.5 emissions by 33 % to 85 % in different scenarios.
