Toxicological Profile of Polyethylene Terephthalate (PET) Microplastic in Ingested (Oregon R) and Its Adverse Effect on Behavior and Development.

Microplastics are readily available in the natural environment. Due to the pervasiveness of microplastic pollution, its effects on living organisms necessitate further investigation. The size, time of exposure, and amount of microplastic particles appear to be the most essential factor in determining their toxicological effects, either organismal or sub-organismal.

Epidemic Rift Valley fever in Saudi Arabia: a clinical study of severe illness in humans.

We describe the clinical patterns and case-fatality rate associated with severe Rift Valley fever (RVF) in patients who were admitted to the Gizan regional referral hospital during an outbreak of RVF in Saudi Arabia from September through November 2000. A total of 165 consecutive patients (136 men and 29 women) were prospectively studied; all were identified according to a strict case definition, were confirmed to have RVF by serologic testing, and were treated according to a predetermined protocol. The major clinical characteristics of RVF included a high frequency of hepatocellular failure in 124 patients (75.
