Article Synopsis
- A wastewater-based epidemiology program was implemented at Technion campus to monitor COVID-19 among 3,300 students living in housing clusters, using 10 manholes for sewage sample collection over eight months.
- The program revealed that 87.4% of samples were negative for SARS-CoV-2, with 11.5% positive, helping the COVID-19 task force track and contain outbreaks effectively, including identifying new cases without prior information.
- Higher levels of the inflammation biomarker ferritin were found in positive sewage samples, suggesting that monitoring such biomarkers in wastewater could help predict and manage future infectious disease outbreaks.
Article Synopsis
- * Researchers found that SARS-CoV-2 RNA is present in urban wastewater, suggesting that monitoring wastewater can track virus activity and serve as an early warning system.
- * In a study conducted in Ashkelon, Israel, changes in wastewater SARS-CoV-2 levels predicted increases in local COVID-19 cases about two weeks before they became clinically visible, using a new metric called Normalized Viral Load (NVL).
Thin films of organically modified silica (ORMOSILS) produced by a sol-gel method were imprinted with whole cells of a variety of microorganisms in order to develop an easy and specific probe to concentrate and specifically identify these microorganisms in liquids (e.g., water).

Here we show that 17beta-estradiol (E(2)) alters microRNA (miRNA) expression profiles in the adult zebrafish (Danio rerio). An association between E(2) and the expression of 25 miRNAs was found 12 h after treatment.

Here, we investigated whether MHC class II-expressing hepatocytes influence in vitro the differentiation of CD4 T cells and in vivo the T-cell response to and control of viral infection.
Methods: Class II transactivator-transgenic hepatocytes that constitutively express MHC class II molecules were used to stimulate CD4 T cells in vitro, and the effector response type of the stimulated CD4 T cells was determined.
