The euglenatides are a family of hybrid polyketide-nonribosomal peptides produced by the unicellular algae Euglena gracilis. These compounds have antiproliferative activity against fungal pathogens and mammalian cancer cell lines. Analysis of E.

Purpose: Baseline surveys were conducted in Tigray region, Ethiopia, in 2013. Since then, rounds of azithromycin mass drug administration (MDA) have been delivered in-line with international guidance. The purpose of these surveys was to assess trachomatous inflammation-follicular (TF) prevalence following those treatments to enable the region to plan the next steps towards elimination of trachoma.

Introduction: Trachoma is caused by the bacterium (). The WHO recommends the SAFE strategy for trachoma elimination: Surgery for trichiasis, Antibiotics, Facial cleanliness and Environmental improvement. Multiple rounds of SAFE implementation have proven insufficient to eliminate trachoma in Ethiopia, where over 50% of the global trachoma burden remains.

Guided by communication accommodation theory, we studied 27 physician reports of patient-physician advanced cancer communication during the COVID-19 pandemic. Advanced cancer communication requires recognizing patients' psychosocial states and collaboratively engaging patients empathetically to develop the shared understanding necessary to guide decision-making. However, physicians found their communication underaccommodated, stemming from personal protection equipment, social distancing, and telemedicine.

The current study focuses on synthesis and characterization of carbonyl functionalized unsymmetrical diorganotellurium(iv) dichlorides (1-5), dibromide (6), and their characterization by elemental analysis, H, C{H}, and Te NMR spectroscopy. In addition to this, compounds 1, 4 and 5 were further confirmed single-crystal X-ray studies. Reduction of all the dichlorides with NaSO affords labile tellurides, which decompose quickly even at room temperature into the more stable symmetric ditellurides, ArTe.
