MXene-Based Flexible Electrodes for Electrophysiological Monitoring.

The advancement of flexible electrodes triggered research on wearables and health monitoring applications. Metal-based bioelectrodes encounter low mechanical strength and skin discomfort at the electrode-skin interface. Thus, recent research has focused on the development of flexible surface electrodes with low electrochemical resistance and high conductivity.

Susceptibility, Immunity, and Persistent Infection Drive Endemic Cycles of Coxiellosis on Dairy Farms.

, a zoonotic bacterium, is prevalent in dairy farms. Some cows develop a persistent infection and shed into milk and occasionally by amniotic fluid at calving. Serological diagnosis of Q fever in humans is performed by phase (Ph)-specific antibody tests; PhII antibodies usually indicate an acute infection, while the development of a chronic infection is characterised by elevated PhI antibody titres.

The immune response to a Coxiella burnetii vaccine in sheep varies according to their natural pre-exposure.

Q fever in humans is caused by Coxiella (C.) burnetii. In 2008 and 2012, cases of Q fever in humans were linked to an infected flock of approximately 650 ewes.

In this research walnut shell powder after modification has been utilized for Co adsorption.

Principal component analysis of texture features derived from FDG PET images of melanoma lesions.

Background: The clinical utility of radiomics is hampered by a high correlation between the large number of features analysed which may result in the "bouncing beta" phenomenon which could in part explain why in a similar patient population texture features identified and/or cut-off values of prognostic significance differ from one study to another. Principal component analysis (PCA) is a technique for reducing the dimensionality of large datasets containing highly correlated variables, such as texture feature datasets derived from FDG PET images, increasing data interpretability whilst at the same time minimizing information loss by creating new uncorrelated variables that successively maximize variance. Here, we report on PCA of a texture feature dataset derived from 123 malignant melanoma lesions with a significant range in lesion size using the freely available LIFEx software.

Year-to-year variability of oil pollution along the Eastern Arabian Sea: The impact of COVID-19 imposed lock-downs.

This study investigated the year-to-year variability in the occurrence, abundance and sources of oil spills in the Eastern Arabian Sea (EAS) using sentinel-1 imagery and identified the potential oil spills vulnerable zones. The four consecutive year's data acquired from 2017 to 2020 (March-May) reveal three oil spill hot spot zones. The ship-based oil spills were dominant over zone's-1 (off Gujarat) and 3 (off Karnataka and Kerala), and the oil field based over zone-2 (off Maharashtra).

Running biomechanical alterations during a 40-km mountain race.

Background: The purpose of this study was to analyze running biomechanical alterations according to different slopes (flat, uphill and downhill) and distance, during a 40-km mountain trail running race.

Methods: Throughout the race, eight runners were equipped with Runscribe inertial units placed on each running shoe. Measurements included spatiotemporal parameters (contact time, step frequency, stride length, running speed), kinetic (impact peak and braking force) and kinematic data (foot pronation velocity and foot pronation excursion).

Safety and Efficacy of Saroglitazar in Nonalcoholic Fatty Liver Patients With Diabetic Dyslipidemia-A Prospective, Interventional, Pilot Study.

Background: Saroglitazar-a unique dual peroxisome proliferator-activated receptor agonist was approved marketing authorization in India in 2013 for diabetic dyslipidemia. Postmarketing studies have additionally shown improvement in liver parameters in diabetic dyslipidemia patients with nonalcoholic fatty liver disease (NAFLD) who received saroglitazar.

Aim: The aim of this study was to evaluate the effect of saroglitazar on liver function test, liver fibrosis score by FibroScan, lipid profiles, HbA1c in NAFLD patients with diabetic dyslipidemia in southern India.

Fate of MV Wakashio oil spill off Mauritius coast through modelling and remote sensing observations.

This study aims at assessing the fate of MV Wakashio oil spill, and the driving forces responsible for possible environmental consequences of polluted coastal region. GNOME simulations were performed, considering various meteo-oceanographic forcings such as (i) winds and currents, (ii) only winds, and (iii) only winds with different diffusion coefficients, and validated with the satellite images. The results revealed that the simulations performed with 'only winds' reasonably match with the satellite observations, indicating that winds are the primary driving forces.

A survey was conducted in the unit with regards to breastfeeding practices which revealed that most babies who were discharged from our nursery were on formula supplements.

Apoptosis Imaging in Oncology by Means of Positron Emission Tomography: A Review.

To date, a wide variety of potential PET-apoptosis imaging radiopharmaceuticals targeting apoptosis-induced cell membrane asymmetry and acidification, as well as caspase 3 activation (substrates and inhibitors) have been developed with the purpose of rapidly assessing the response to treatment in cancer patients. Many of these probes were shown to specifically bind to their apoptotic target in vitro and their uptake to be enhanced in the in vivo-xenografted tumours in mice treated by means of chemotherapy, however, to a significantly variable degree. This may, in part, relate to the tumour model used given the fact that different tumour cell lines bear a different sensitivity to a similar chemotherapeutic agent, to differences in the chemotherapeutic concentration and exposure time, as well as to the different timing of imaging performed post-treatment.
