Attitude towards psychiatry and mental illness among medical students: A cohort study.

Background Medical students' attitude towards psychiatry (ATP) and mental illness will impact their choice of psychiatry as a future specialization and the quality of mental healthcare that they deliver to their patients. There is a paucity of longitudinal research on students' ATP and mental illness at different periods during medical school. We aimed to assess the attitudes of a cohort of medical undergraduates towards psychiatry and mental illness, before and after a clinical psychiatry rotation.

Description of a new troglophilic loach, Schistura densiclava (Teleostei: Nemacheilidae) from Meghalaya, northeast India.

Integrative taxonomy reveals a new troglophilic species of Schistura, from a cave-dwelling population inhabiting stream draining (Barak-Surma-Meghna drainage) through the Krem (=cave) Mawjymbuin in East Khasi Hills of Meghalaya. Morphologically, the new species is easily distinguished from its congeners in having a combination of characters, including a unique colour pattern in the form of 14-20 greyish black to faint black bars overimposed to a black midlateral stripe on a greyish brown to pale beige (yellowish green in life); pre-dorsal bars thin, numerous, wider than interspaces, weakly contrasted, sometimes broken and/or incomplete; bars posterior of anal-fin base numerous and variable, mostly broken or incomplete, located on lower flank, weakly contrasted; a complete lateral line; presence of an axillary pelvic lobe; an uninterrupted thick black stripe along the base of the dorsal fin; an incomplete black basicaudal bar, dissociated, occupying median one-third of caudal-fin base; conspicuous black botch on the procurrent rays of the upper lobe of the caudal fin; and a type of sexual dimorphism: males with slender body, bars mostly irregular on flanks and slightly puffy cheek with greater lateral head length; females with regular-shaped bars and swollen body. Analysis of the mitochondrial cytochrome c oxidase I (COI) gene sequence of the new species shows significant genetic divergence with p distances ranging 4.

Mitogenome of Neolissochilus pnar, the largest cavernicolous species of Mahseer.

The study of the mitogenome of Neolissochilus pnar, the world's largest cave fish, uncovered its structural features, gene content and evolutionary dynamics within mahseer. Its mitogenome is of 16,440 base pairs, resembling those of the teleost species and exhibits a high degree of conservation in genes arrangement. It comprises 37 mitochondrial genes, including 13 protein-coding genes (PCGs), 22 tRNA genes (tRNAs), 2 rRNA genes (rRNAs) and a control region.

Schistura syngkai, a new fish species (Teleostei: Nemacheilidae) from Meghalaya, northeast India.

Schistura syngkai, a new stone loach, is described from the Twahdidoh Stream of Wahblei River (Surma-Meghna drainage) in Meghalaya, northeast India. It is unique among its Indian congeners in having a prominent dark-brown to blackish mid-lateral stripe about an eye diameter or more in width, overlain on 12-18 vertically-elongate black blotches on a golden-brown to amber body. Additionally, the species possesses an incomplete lateral line and a slightly emarginate caudal fin, and exhibits no apparent sexual dimorphism.
