Phylogenetic and diversity analyses revealed that leek yellow stripe virus population consists of three types: S, L, and N.

Phylogenetic and evolutionary analyses were performed on the P1 and CP genes of global isolates to clarify the phylogrouping of leek yellow stripe virus (LYSV, genus Potyvirus), a pathogen affecting Allium spp. worldwide, into different types based on genetic variation and host species. The constructed phylogenetic trees divided the isolates into three major groups: S, L, and N.

Prunus necrotic ringspot virus in Turkey: an immigrant population.

An outbreak in northwestern Turkey of prunus necrotic ringspot virus (PNRSV, genus Ilarvirus, family Bromoviridae) was sampled in 2016-2018. Gene sequences from these isolates, together with all of the gene sequence data for this virus in the GenBank database (>300 non-recombinant coat protein (CP) genes and 20 complete genomic sequences) were analysed to determine the relationship of the Turkish PNRSV isolates to those from other parts of the world. Phylogenetic and population genetic methods independently showed that the most recent common ancestor of the world PNRSV population was probably American, not Eurasian.

Effect of sedation with midazolam or propofol on patient's comfort during cancer chemotherapy infusion: a prospective, randomized, double-blind study in breast cancer patients.

Nausea, vomiting and anxiety related to administration of cancer chemotherapy remain significant problems. This randomized, clinical trial was undertaken to evaluate the effect of sedation on the patient's comfort during chemotherapy infusion in patients with breast cancer. Forty-five breast cancer patients were randomized into three groups: Group I--chemotherapy, control, Group II--midazolam+chemotherapy, and Group III--propofol+chemotherapy.
