This study evaluated the metabolomics profiling, anti-proliferative and pro-apoptotic effects of strigol/albumin/chitosan nanoparticles (S/A/CNP) on HepG2 cell line.

Hemorrhagic fever in Saudi Arabia: challenge to public health, effective management and future considerations.

Background: Viral hemorrhagic fevers (VHF) refers to a group of febrile illnesses caused by different viruses that result in high mortality in animals and humans. Many risk factors like increased human-animal interactions, climate change, increased mobility of people and limited diagnostic facility have contributed to the rapid spread of VHF.

Materials: The history of VHFs in the Saudi Arabian Peninsula has been documented since the 19 century, in which many outbreaks have been reported from the southwestern region of Saudi Arabia.

Dominance of the ON1 Genotype of RSV-A and BA9 Genotype of RSV-B in Respiratory Cases from Jeddah, Saudi Arabia.
