Vitamin D deficiency can be regarded as one of the overgrowing health problem in all of the world. Evidence from a clinical trial suggested a role for probiotic bacteria in increasing vitamin D. However, probiotic's effect is strain specific and this effect should be confirmed about different strains.

Acrocyanosis and digital necrosis are associated with poor prognosis in COVID-19.

Acrocyanosis and digital necrosis, which caused by microangiopathic and immunothrombosis phenomenon, may accompanied by microvascular involvement of other organs. Therefore, this finding can play a prognostic role in covid-19 outcome.

The efficient biogeneration of Ag and NiO nanoparticles from VPLE and a study of the anti-diabetic properties of the extract.

leaf extract (VPLE) is used to mediate the green biosynthesis of Ag and NiO nanoparticles in aqueous solutions under mild conditions. The synthesized nanoparticles, with a narrow size range and good distribution, are characterized by means of powder X-ray diffraction (PXRD), Fourier-transform infrared (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM) techniques. SEM and TEM micrographs proved formation of mostly spherical or ellipsoidal nanoparticles with little agglomeration, and the average particle size was less than 20-35 nm for both types of nanoparticle.
