Integrated use of inverse and biotic ligand modelling for lake water quality resilience estimation: A case of Ramsar wetland, (Deepor Beel), Assam, India.

Environ Res 2021 Jun 7:111397. Epub 2021 Jun 7.

Discipline of Earth Sciences, Indian Institute of Technology, Gandhinagar, 382355, India. Electronic address:

The present study evaluates the vulnerability of a lake system due to the combined exposure of toxic metals, major ions and mineral dissociation. The hydro-chemistry of the Deepor Beel lake reveals the dominance of carbonate weathering with strong evidences of ion-exchange reaction occurring throughout the monsoon season of 2014 and 2015. Through an integrated application of multivariate analysis, the occurrence of albite weathering was confirmed, though as an isolated incidence only, along-with substantial evidence of waste intrusion from fertilizer industries.

Small-scale dissolution test screening tool to select potentially substandard and falsified (SF) medicines requiring full pharmacopoeial analysis.

Sci Rep 2021 Jun 9;11(1):12145. Epub 2021 Jun 9.

Medi-Quality Security Institute, Graduate School of Medical Sciences, Kanazawa University, Kanazawa, 920-1192, Japan.

The purpose of this study was to design a convenient, small-scale dissolution test for extracting potential substandard and falsified (SF) medicines that require full pharmacopoeial analysis. The probability of metronidazole samples complying with the US Pharmacopoeia (USP) dissolution test for immediate-release tablet formulations was predicted from small-scale dissolution test results using the following criteria: (1) 95% confidence interval lower limit (95% CI) of the average dissolution rate of any n = 3 of n = 24 units of each sample, and (2) average and minimum dissolution rates for any n = 3 of n = 24 units. Criteria values were optimized via bootstrap sampling with Thinkeye data-mining software. Read More

Frailty is associated with increased mortality in older adults 12 months after discharge from post-acute care in Swiss nursing homes.

J Frailty Aging 2021 ;10(3):233-236

Michael Gagesch, MD, Dept. of Geriatrics and Aging Research, University Hospital Zurich, Raemistrasse 100, 8091 Zurich, Switzerland,

Frail older adults with ongoing care needs often require post-acute care (PAC) following acute hospitalization when not eligible for specific rehabilitation. Long-term outcomes of PAC in this patient group have not been reported for Switzerland so far. In the present report, we investigated 12-month mortality in regard to frailty status upon admission to PAC in a nursing home setting. Read More

Potential role of free-radical processes in biomolecules damage during COVID-19 and ways of their regulation.

Free Radic Res 2021 Jun 4:1-27. Epub 2021 Jun 4.

Belarusian State Medical University, Dzerzhinski av., 83, 220116, Minsk, Republic of Belarus.

It has been shown that the development of coronavirus infection (COVID-19), especially in severe cases, is accompanied by hypoxia as a result of several pathological processes: alveolar blood supply disorders, hemolysis, COVID-associated coagulopathy. Under these conditions, the level of reactive oxygen species is increased and it is more likely that free-radical damage to biomolecules is caused by the process of free-radical fragmentation than oxidation. In contrast to the oxidation process, free-radical fragmentation reactions are more effectively inhibited by oxidizing agents than reducing agents. Read More

Population pharmacokinetics of immediate-release and modified-release paracetamol and its major metabolites in a supratherapeutic dosing study.

Clin Toxicol (Phila) 2021 Jun 3:1-8. Epub 2021 Jun 3.

School of Pharmacy, University of Otago, Dunedin, New Zealand.

Objectives: Overdose with paracetamol modified-release (MR) formulation, a bilayer tablet containing 69% slow-release component, has been increasing since its introduction to the market. However, little evidence exists for the management of MR paracetamol overdose. We aimed to develop a population pharmacokinetic (PK) model for immediate-release (IR) and MR paracetamol and its major metabolism, and quantitatively understand the formulation difference in toxicity assessment based on the nomogram line.

X-ROS Signaling Depends on Length-Dependent Calcium Buffering by Troponin.

Cells 2021 May 13;10(5). Epub 2021 May 13.

School of Systems Biology and The Krasnow Institute for Advanced Study, George Mason University, Fairfax, VA 22030, USA.

The stretching of a cardiomyocyte leads to the increased production of reactive oxygen species that increases ryanodine receptor open probability through a process termed X-ROS signaling. The stretching of the myocyte also increases the calcium affinity of myofilament Troponin C, which increases its calcium buffering capacity. Here, an integrative experimental and modeling study is pursued to explain the interplay of length-dependent changes in calcium buffering by troponin and stretch-activated X-ROS calcium signaling.

Centre for Agriculture and Biosciences International (CABI), Opposite 1-A, Data Gunj Baksh Road Satellite Town, Rawalpindi 43600, Pakistan.

Parthenium, or , has extended its range in Pakistan throughout Punjab and into Khyber Pakhtunkhwa, the Federally Administrated Tribal Areas, Azad Jammu and Kashmir, and Sindh Provinces. Without control measures against parthenium, the negative impacts of this weed will go unchecked having deleterious effects on native biodiversity, human and animal health, as well as crop productivity.

A Rational Evaluation of the Syncope Patient: Optimizing the Emergency Department Visit.

Medicina (Kaunas) 2021 May 21;57(6). Epub 2021 May 21.

Libin Cardiovascular Institute of Alberta, University of Calgary, Calgary, AB T2N 4Z6, Canada.

Syncope accounts for up to 2% of emergency department visits and results in the hospitalization of 12-86% of patients. There is often a low diagnostic yield, with up to 50% of hospitalized patients being discharged with no clear diagnosis. We will outline a structured approach to the syncope patient in the emergency department, highlighting the evidence supporting the role of clinical judgement and the initial electrocardiogram (ECG) in making the preliminary diagnosis and in safely identifying the patients at low risk of short- and long-term adverse events or admitting the patient if likely to benefit from urgent intervention.

In vivo flow cytometry reveals a circadian rhythm of circulating tumor cells.

Light Sci Appl 2021 May 28;10(1):110. Epub 2021 May 28.

State Key Laboratory of Oncogenes and Related Genes, Shanghai Cancer Institute, Med-X Research Institute and School of Biomedical Engineering, Shanghai Jiao Tong University, 200030, Shanghai, China.

Circulating tumor cells (CTCs) is an established biomarker of cancer metastasis. The circulation dynamics of CTCs are important for understanding the mechanisms underlying tumor cell dissemination. Although studies have revealed that the circadian rhythm may disrupt the growth of tumors, it is generally unclear whether the circadian rhythm controls the release of CTCs. Read More

Microvascular imaging and monitoring of hemodynamic changes in the skin during arterial-venous occlusion using multispectral raster-scanning optoacoustic mesoscopy.

Photoacoustics 2021 Jun 20;22:100268. Epub 2021 Apr 20.

Laboratory of Bio Optical Imaging, Singapore Bioimaging Consortium, Agency of Science, Technology and Research (ASTAR), Singapore.

The ability to monitor oxygen delivery in microvasculature plays a vital role in measuring the viability of skin tissue and the probability of recovery. Using currently available clinical imaging tools, it is difficult to observe non-invasive hemodynamic regulation in the peripheral vessels. Here we propose the use of a novel multispectral raster-scanning optoacoustic mesoscopy (RSOM) system for noninvasive clinical monitoring of hemodynamic changes in the skin microvasculature's oxy- (HbO) and deoxy-hemoglobin (Hb), total hemoglobin (HbT) and oxygen saturation (rsO).
