Abstract
Hetero-bimetallic ruthenium(II) complexes (PRAFIZ and PRBFIZ) containing acetyl ferrocene (AFIZ)/benzoyl ferrocene isonicotinic hydrazone ligands (BFIZ) were synthesized and characterized by various spectral and analytical techniques. The structure of acetyl ferrocene isonicotinic hydrazone (AFIZ) and the complex PRBFIZ was confirmed by X-ray crystallography. The hydrazide ligands coordinated in a bidentate monobasic fashion using their N1 hydrazinic nitrogen and enolic oxygen atoms. The binding interactions of the ligands and complexes were examined using Calf-Thymus DNA (CT-DNA) and bovine serum albumin (BSA). Scanning Electron Microscopic (SEM) experiments clarified the efficient binding interaction of the ligands and complexes with BSA. The results of in vitro cytotoxicity studies on MDA-MB-261 breast cancer cells and A549 human lung cancer cells and cell morphological analysis results through staining assays clearly indicated the cytotoxic nature of the complexes.

Abstract
In the present investigation, xylooligosaccharides were produced from wheat bran and wheat bran extracted xylan through enzymatic hydrolysis using xylanase from novel Enterobacter hormaechei KS1. Xylooligosaccharides/reducing sugars production from wheat bran was found maximum (374 mg/g) when 4.0% of wheat bran was treated with 375 units (IU/mL) of Enterobacter hormaechei KS1 xylanase at pH 6.0 and incubated at 50 °C for 24 h of incubation. In case of wheat bran extracted xylan 419 mg/g of xylooligosaccharides were produced when 3% of extracted xylan was incubate for 8 h. Analysis of the enzymatic hydrolysate through high performance liquid chromatography equipped with refractive index detector showed the presence of xylose, xylopentose and xylohexose. The decrease in pH with 1.0% dose of xylooligosacchaides produced from extracted xylan hydrolysis using E. hormaechei KS1 xylanase showed more decrease with L. rhamnosus (6.72 to 5.94) followed by L. brevis (6.71 to 6.15) and L. plantarum (6.71 to 6.41). In case of increase in optical density both wheat bran and wheat bran extracted xylan generated xylooligosaccharides exhibited similar pattern i.e., L. rhamnosus > L. plantarum > L. brevis.

Abstract
BACKGROUND This study presents our data on mortality in end stage renal disease (ESRD) patients on peritoneal dialysis (PD) who developed COVID-19. MATERIALS AND METHODS Sri Padmavathi Medical College Hospital, Sri Venkateswara Institute of Medical Sciences University, was designated the State COVID Hospital in March 2020. In a retrospective observational study, we collected the data of ESRD patients on PD and identified the risk factors for mortality. RESULTS Prior to the pandemic, 136 patients with ESRD were on peritoneal dialysis at our Institute. Among them, 27 (19.8%) eventually developed COVID-19, and 14 of them (51.8%) died. Serum albumin levels were lower and D-dimer levels were significantly higher in deceased patients than in survivors. DISCUSSION The mortality rate in ESRD patients on PD with COVID-19 at our institution was higher than in other published studies.

Abstract
Heavy metal pollution in soil and water is a potential threat to human health as it renders food quality substandard. Different biosorbents such as microbial and agricultural biomass have been exploited for heavy metal immobilization in soil and sorptive removal in waters. Biosorption is an effective and sustainable method for heavy metal removal in soil and water, but the inherent challenges are to find cheap, selective, robust, and cost-effective bioadsorbents. Microbial and agricultural biomass and their modified forms such as nanocomposites and carbonaceous materials (viz., biochar, nanobiochar, biocarbon), might be useful for sequestration of heavy metals in soil via adsorption, ion exchange, complexation, precipitation, and enzymatic transformation mechanisms. In this review, potential biosorbents and their metal removal capacity in soil and water are discussed. The microbial adsorbents and modified composites of agricultural biomasses show improved performance, stability, reusability, and effectively immobilize heavy metals from soil and water. In the future, researchers may consider the modified composites, encapsulated biosorbents for soil and water remediation.

Abstract
Background Hypofractionation is now becoming the standard of care in breast irradiation. The aim of this study was to assess the toxicities and outcomes in patients with breast cancer treated with hypofractionated radiotherapy (HFRT). Methods Patients with localized breast cancer who received adjuvant HFRT between 2013 and 2015 with a minimum follow-up of 6 months following radiation were included in this prospective study. Late toxicities were assessed using CTCAE v 4 and included chest/breast pain, limb pain, limb edema, skin pigmentation, skin fibrosis, and shoulder movement restriction. Outcomes assessed included locoregional control, disease-free survival, and overall survival. Statistical analysis was done using Microsoft Excel and SPSS v22. Results A total of 81 patients fulfilled the inclusion criteria, of which 19 patients had died during follow-up. Regional nodal irradiation was done in 63 (77.8%) patients using the same hypofractionated schedule of 40 Gy in 15 fractions. Late toxicities were assessed for 62 patients. The median follow-up following the course of hypofractionated radiation was 45 months (range 14 - 65 months). Late toxicities were assessed for 62 patients. Grade 1/2 chest/breast pain, limb pain, limb edema, skin pigmentation, skin fibrosis, and shoulder movement restriction were seen in 11%, 12%, 7%, 6%, 8%, and 11% of cases, respectively. Distant recurrences were seen in 8% of cases, and there were no locoregional recurrences. Five-year overall survival was 76.5%. Conclusion HFRT to whole breast or chest wall and the regional nodal areas was well-tolerated with acceptable rates of late toxicities on follow-up.

Abstract
Thyroxine (3,5,3',5'-tetraiodo thyronine) is administered to patients suffering from endemic goiter as also in cases of non-iodine deficient ethiology and hypothyroidism. It is suggested that the uptake of thyroxine can be monitored by assessing the levels of the same in the urine of patients under treatment. For the purpose, a highly sensitive and selective ion chromatographic procedure is developed. The sample of urine is treated with sodium hydroxide and UV irradiated to convert iodine in thyroxine to iodide. Subsequently, iodide is separated on an anion exchanger AS 4A column using 50 mM NaOH as the eluent and determined spectrophotometrically at 226 nm.
