Background: Splice-disrupt genomic variants are one of the causes of cancer-causing errors in gene expression. Little is known about splice-disrupt genomic variants.
Methods And Results: Here, pattern of splice-disrupt variants was investigated using 21,842,764 genomic variants in different types of prostate cancer.
The exploration of new bioactive compounds from natural resources as alternatives to synthetic chemicals has recently attracted the attention of scientists and researchers. To our knowledge, the essential oil (EO) of has not yet been explored. Thus, the present study was designed to explore the EO chemical profile of for the first time, as well as evaluate its antioxidant and antibacterial activities, particularly the extracts of this plant that have been reported to possess various biological activities.

Therefore, risk assessments of specific nanoparticles in occupational and environmental exposure are essential before their large-scale production and applications, especially in medicine and for usage in household items. In this study, the effects of five different metal nanoparticles on the structure, stability, and function of four metabolic enzymes were evaluated using various biophysical techniques.

This hyperendemicity poses a greater risk of secondary infections in human health system. This is a major issue which leads to apprehension amongst the researchers and health organizations and thus requires regular epidemiological surveillance.

Proteins are prime targets of heavy metal stress, however, the underlying mechanisms and its impact on heme proteins is still not entirely clear.
Objective: To analyze the deleterious effect of heavy metals such as cadmium, chromium and mercury on conformation of two proteins namely, cytochrome c and myoglobin.
The camel has several biochemical, physiological, and anatomical features to withstand the harsh desert climate. Camel eye lens contains a novel protein (ζ-crystallin) in bulk quantity. Previous reports suggest that non-enzymatic glycation of eye lens proteins plays an important role in the etiology of cataract.

Limited information is available on molecular epidemiology of respiratory syncytial virus (RSV) from Saudi Arabia. An attempt was made to identify and characterize RSV strains in nasopharyngeal aspirates collected from hospitalized symptomatic ARI pediatric patients with <5 years of age from Riyadh, Saudi Arabia during 2016.

Respiratory syncytial virus (RSV) is a major pathogen of acute respiratory tract infection (ARI) in different geographical regions including Saudi Arabia. Numerous hospital-based investigations have revealed the RSV prevalence between 0.2-54% in the paediatric population with ARI/ALRI from Saudi Arabia during 1991-2015.

Camelus dromedarius is well-adapted to survive in extreme desert climate and it has GSTs, for which limited information is available. This study investigated the structure-function and thermodynamic properties of a mu-class camel GST (CdGSTM1) at different pH.
View Article and Find Full Text PDFAmyloid fibrils are highly ordered protein assemblies known to contribute to the pathology of a variety of genetic and aging-associated diseases. Here, we have investigated the aggregation propensity of lysozyme in the presence of a negatively charged surfactant (SDS) and evaluated the anti-aggregation activity of rutin. Multiple approaches such as turbidity measurements, dye binding assays, intrinsic fluorescence, circular dichroism (CD), transmission electron microscopy (TEM), MTT and comet assays have been used for this purpose.
