The SARS CoV-2 spike directed non-neutralizing polyclonal antibodies cross-react with Human immunodeficiency virus (HIV-1) gp41.

Cross-reactivity among the two diverse viruses is believed to originate from the concept of antibodies recognizing similar epitopes on the two viral surfaces. Cross-reactive antibody responses have been seen in previous variants of SARS and SARS-CoV-2, but little is known about the cross reactivity with other similar RNA viruses like HIV-1. In the present study, we examined the reactivity the SARS-CoV-2 directed antibodies, via spike, immunized mice sera and demonstrated whether they conferred any cross-reactive neutralization against HIV-1.

BiWO and FeWO Nanocatalysts for the Electrochemical Water Oxidation Process.

Polyvinylpyrrolidone (PVP)-assisted nanocatalyst preparation was succeeded by employing a controlled solvothermal route to produce efficient electrodes for electrochemical water-splitting applications. BiWO and FeWO nanocatalysts have been confirmed through the strong signature of (113) and (111) crystal planes, respectively. The binding natures of Bi-W-O and Fe-W-O have been thoroughly discussed by employing X-ray photoelectron spectroscopy which confirmed the formation of BiWO and FeWO.

Morphology-Dependent Photoelectrochemical and Photocatalytic Performance of -Bi₂O₃ Nanostructures.

Simple one-step solvothermal route was used to synthesize -Bi₂O₃ nanostructures. Well-defined nanoflowers and finite nanorods surface morphology of the samples were revealed. The physical characterization and material confirmation was explored by employing X-ray diffraction (XRD), Raman, photoluminescence (PL), and Fourier transform infrared (FTIR) studies.

BiVO₄ Nanostructures for Photoelectrochemical (PEC) Solar Water Splitting Applications.

We reported a simple and economical SDS (sodium dodecyl sulfate) assisted BiVO₄ solvothermal synthesis of BiVO₄ nanostructures. The implementation of pristine and SDS assisted BiVO₄ nanostructure as photoanode in photoelectrochemical (PEC) water splitting was investigated. The good crystalline nature, defects present in the material, recombination nature and vibrational properties of the synthesized BiVO₄ nanostructures have been analyzed and confirmed by XRD, Raman, PL and FTIR studies.

Groove pancreatitis-a great mimicker.

Groove pancreatitis is an uncommon form of chronic pancreatitis affecting the "groove" between the pancreatic head, duodenum and common bile duct. Many radiologists remain unfamiliar with this entity, with only a few descriptions of it existing in the radiology and pathology literature. The exact underlying cause of groove pancreatitis is unclear, although there are strong associations with peptic ulcer disease, smoking, long-term alcohol abuse, functional obstruction of the duct of Santorini and Brunner gland hyperplasia.
