COVID 19 infection clinical features in pediatric patients in Southwestern Iran: a cross-sectional, multi-center study.

With the SARS-CoV-2 pandemic, the impact of recent coronavirus, especially in children, cannot be ignored. In this study, we evaluated the SARS-CoV-2 infection rates and associated features in children less than 18 years of age in "Fars" and "Kohgiluyeh and Boyer Ahmad", provinces, Iran. 5943 children who were suspected cases to SARS-CoV-2 infection were enrolled in this study.

The rates and symptoms of natural and breakthrough infection pre- and post- Covid-19 non-mRNA vaccination at various peaks amongst Iranian healthcare workers.

Background/aims: The aim of this study was to determine the rate of natural and breakthrough infection and related symptoms of Covid-19 amongst Iranian healthcare workers (HCWs) who were vaccinated by different non-mRNA-based vaccines at peak points.

Methods: In this cross-sectional study, the RT-PCR test was performed for a total of 10,581 HCWs suspicious of Covid-19 infection. For each HCW, the frequency of SARS-CoV-2 infection and the time of transmission based on vaccination administration time and schedule were examined during different waves of the pandemic.

Effect of COVID-19 on healthcare workers' morbidity and mortality compared to the general population in Kohgiluyeh and Boyer-Ahmad Province, Iran.

During the Covid-19 pandemic, the adverse effects of recent coronaviruses on healthcare professionals cannot be ignored. This study compared the admission rates due to Covid-19 and characteristics of hospitalized healthcare workers with the general population of Kohgiluyeh and Boyer-Ahmad (K.B) province.

Immobilization of enzymes on nanoinorganic support materials: An update.

Despite the widespread use in various industries, enzyme's instability and non-reusability limit their applications which can be overcome by immobilization. The nature of the enzyme's support material and method of immobilization affect activity, stability, and kinetics properties of enzymes. Here, we report a comparative study of the effects of inorganic support materials on immobilized enzymes.
