Non-prescription pharmacy syringes sales to people who inject drugs (PWID) in Khartoum, Sudan: policy, practice, and perceptions.

People who inject drugs (PWID) are at high risk of contracting blood-borne infections. Many developed countries started a needle exchange program to provide PWID with sterile syringes. In Sudan, healthcare professionals are exposed to legal liability if they cooperate with people who use drugs; therefore, the accessibility to sterile syringes without prescription depends heavily on pharmacists' knowledge and attitude toward PWID.

NeoCoV Is Closer to MERS-CoV than SARS-CoV.

Recently, Coronavirus has been given considerable attention from the biomedical community based on the emergence and isolation of a deadly coronavirus infecting human. To understand the behavior of the newly emerging MERS-CoV requires knowledge at different levels (epidemiologic, antigenic, and pathogenic), and this knowledge can be generated from the most related viruses. In this study, we aimed to compare between 3 species of Coronavirus, namely Middle East Respiratory Syndrome (MERS-CoV), Severe Acute Respiratory Syndrome (SARS-CoV), and NeoCoV regarding whole genomes and 6 similar proteins (E, M, N, S, ORF1a, and ORF1ab) using different bioinformatics tools to provide a better understanding of the relationship between the 3 viruses at the nucleotide and amino acids levels.

Calibrating abundance indices with population size estimators of red back salamanders (Plethodon cinereus) in a New England forest.

Herpetologists and conservation biologists frequently use convenient and cost-effective, but less accurate, abundance indices (e.g., number of individuals collected under artificial cover boards or during natural objects surveys) in lieu of more accurate, but costly and destructive, population size estimators to detect and monitor size, state, and trends of amphibian populations.
