Patient-centered home cancer screening attitudes during SARS-CoV-2 pandemic.

COVID-19 has caused disruptions in health care, in particular cancer screenings. The primary aim of our work was to evaluate the degree to which populations were accepting of home-based screenings for colorectal cancer (CRC) and cervical cancer (primary HPV testing). Three groups of adults having distinct health burdens which may affect acceptance of home-based cancer screening were identified through outpatient electronic medical records as follows as either having survived a COVID hospitalization, having been positive for non-COVID respiratory illness or having type 2 diabetes.

Glycogen, poly(3-hydroxybutyrate) and pigment accumulation in three strains when exposed to a stepwise increasing salt stress.

The cyanobacterial genus is of particular interest to science and industry because of its efficient phototrophic metabolism, its accumulation of the polymer poly(3-hydroxybutyrate) (PHB) and its ability to withstand or adapt to adverse growing conditions. One such condition is the increased salinity that can be caused by recycled or brackish water used in cultivation. While overall reduced growth is expected in response to salt stress, other metabolic responses relevant to the efficiency of phototrophic production of biomass or PHB (or both) have been experimentally observed in three strains at stepwise increasing salt concentrations.

PHB Producing Cyanobacteria Found in the Neighborhood-Their Isolation, Purification and Performance Testing.

Cyanobacteria are a large group of prokaryotic microalgae that are able to grow photo-autotrophically by utilizing sunlight and by assimilating carbon dioxide to build new biomass. One of the most interesting among many cyanobacteria cell components is the storage biopolymer polyhydroxybutyrate (PHB), a member of the group of polyhydroxyalkanoates (PHA). Cyanobacteria occur in almost all habitats, ranging from freshwater to saltwater, freely drifting or adhered to solid surfaces or growing in the porewater of soil, they appear in meltwater of glaciers as well as in hot springs and can handle even high salinities and nutrient imbalances.

Panoramix SUMOylation on chromatin connects the piRNA pathway to the cellular heterochromatin machinery.

Nuclear Argonaute proteins, guided by small RNAs, mediate sequence-specific heterochromatin formation. The molecular principles that link Argonaute-small RNA complexes to cellular heterochromatin effectors on binding to nascent target RNAs are poorly understood. Here, we explain the mechanism by which the PIWI-interacting RNA (piRNA) pathway connects to the heterochromatin machinery in Drosophila.

Patient-Centered Home Cancer Screening Attitudes During COVID-19 Pandemic.

The COVID-19 pandemic disrupted health care delivery of cancer screenings. The primary aim of our work was to evaluate the degree to which populations were accepting of home-based screenings for colorectal cancer (CRC) and cervical cancer (ie, primary human papillomavirus [HPV] testing). Three groups of adults having distinct health burdens that may affect acceptance of home-based cancer screening were identified through outpatient electronic medical records: those having survived a COVID-19 hospitalization; those having been positive for a non-COVID-19 respiratory illness; or those having type 2 diabetes.
