Hematological and immunological responses in the African catfish Clarias gairepinus exposed to sublethal concentrations of herbicide Ronstar®.

The aim of the study was to investigate the effects of sublethal concentrations (0.3, 0.6 and 1.

Phylogeography and genetic diversity of the copepod family Cyclopidae (Crustacea: Cyclopoida) from freshwater ecosystems of Southeast Nigeria.

Background: Copepods are key components of aquatic ecosystems and can help regulate the global carbon cycle. Much attention has been paid to the species diversity of copepods worldwide, but the phylogeography and genetic diversity of copepods in Nigeria is unexplored.

Results: Using a mitochondrial cytochrome c oxidase subunit I marker, we preformed phylogenetic and phylogeographic analyses for Cyclopidae copepods in Southeast Nigeria.

Genome Sequences of Two F1 Subcluster Bacteriophages, Burwell21 and Nivrat, Isolated Using the Bacterial Host Mycobacterium smegmatis.

The mycobacteriophages Burwell21 and Nivrat are two F1 cluster bacteriophages isolated from different soil samples in Charlotte, NC. Burwell21 has a 58,098-base-pair double-stranded DNA genome, with 99 protein-coding genes predicted, whereas Nivrat has a 58,009-base-pair genome, with 102 protein-coding genes predicted.

Genome Sequences of Mycobacteriophages Ebony and Holeinone.

Ebony and Holeinone represent the first mycobacteriophages isolated from Charlotte, NC, soil samples, using the host strain mc155. Ebony has a 52,152-bp genome and showed similarity to other phages in the A11 subcluster. Holeinone has a 67,044-bp genome and showed similarity to other phages in the B2 subcluster.

GIANT PSEUDOANEURYSM OF A SPLANCHNIC ARTERY; A Case Report.

A true aneurysm is defined as an enlargement of an artery resulting in a diameter more than 1.5 times the anatomic size. It can be fusiform when it covers the entire perimeter of the vessel, or saccular when it bulges on one side of the artery.
