Introduction: Multiple myeloma is a heterogeneous disease with different survival times among patients. Accurate prediction of prognosis in multiple myeloma is essential, as patients with a shorter survival time may require early bone marrow transplantation (BMT) and more advanced chemotherapy as a part of their first-line treatment. In the present study, a parameter, depicted by ga...

Background: Radioprotective effect of famotidine was previously shown on radiation induced micronuclei and chromosomal aberrations in human peripheral lymphocytes and mouse bone marrow cells however, its radioprotective property has never been studied in mouse spermatogenesis. It was also shown that vitamin C as an antioxidant also exert its radioprotective effect on many biological s...

The prompt emission of most gamma-ray bursts (GRBs) typically exhibits a non-thermal Band component. synchrotron radiation in the popular internal shock model is generally put forward to explain such However, low-energy photon index α∼−1.5 predicted by inconsistent with observed value α∼−1. Here, we investigate evolution magnetic field during propagation shocks within an ultrarelativistic outfl...

In this work we revisit the steady state, spherically symmetric gas accretion problem from non-relativistic regime to ultra-relativistic one. We first perform a detailed comparison between Bondi and Michel models, show how mass rate in solution approaches constant value as fluid temperature increases, whereas corresponding continually decreases, difference these two predicted values becoming ar...

This study evaluates drought at Lashkargah, Farah, Adraskan, and Gardandiwal stations in Helmand River Basin (HRB) Afghanistan to determine appropriate indices for the basin. Thirty seven years of monthly recorded precipitation data from 1979 2015 are employed with different index (DI) methods which include Standardized Precipitation Index (Normal-SPI, Log-SPI, Gamma-SPI), Percent Normal (PN), ...

BACKGROUND In the absence of liver biopsy, the World Health Organization recommends non-invasive tests, such as aspartate aminotransferase to platelet ratio index and FIB-4, to assess liver fibrosis in patients with chronic hepatitis B. However, these tests are not well validated in sub-Saharan Africa. Recently, a new marker, gamma-glutamyl transpeptidase to platelet ratio, was found to be more...
