Khat Use Patterns, Associated Features, and Psychological Problems in a Khat-Treatment-Seeking Student Sample of Jimma University, Southwestern Ethiopia.

Khat () is a traditionally used substance in African and Arab countries that contains the amphetamine-like alkaloid cathinone. Khat use among Ethiopian students is a growing concern. This study aims to describe khat use, psychological problems, and motivation to change and to determine associated factors of khat use among students from Jimma University seeking psychological assistance.

Relevance of Leptospira in boar and for the development of alternative antimicrobial concepts in boar semen preservation.

Leptospirosis is a zoonotic disease of importance to public health and in livestock productions. It causes significant economic losses in pig breeding farms worldwide. However, actual transmission cycles and disease epidemiology in the pig population remain largely unknown.

Ecological impacts and management implications of reef walking on a tropical reef flat community.

Continued growth of tourism has led to concerns about direct and indirect impacts on the ecology of coral reefs and ultimate sustainability of these environments under such pressure. This research assessed impacts of reef walking by tourists on a relatively pristine reef flat community associated with an 'ecoresort' on the Great Barrier Reef, Australia. Heavily walked areas had lower abundances of live hard coral but greater amounts of dead coral and sediment.

Detection of Cryptosporidium hominis and novel Cryptosporidium bat genotypes in wild and captive Pteropus hosts in Australia.

Spillover of zoonotic pathogens from wildlife to humans has been identified as a primary threat to global health. In contrast, the process of reverse pathogen transmission (zooanthroponosis), whereby pathogens move from humans into wildlife species is still largely unexplored. Globally, increasing urbanisation and habitat loss are driving many wildlife species into urban and regional centres.

Interaction of fluorescent phospholipids with cyclodextrins.

Fluorescent analogs of phospholipids are often employed to investigate the structure and dynamics of lipids in membranes. Some of those studies have used cyclodextrins e.g.

Molecular rods with oligospiroketal backbones as anchors in biological membranes.

Getting stuck in: A hydrophobic molecular rod with terminal fluorescent moieties has been synthesized. The insertion of the rod into membranes was investigated and shown to incorporate efficiently into model and biological membranes (see picture; gray C, blue N, red O). Those rods can be used as stable membrane-associated anchors for functionalization of membrane surfaces.

Determinants of subjective quality of life in post acute patients with schizophrenia.

Although Quality of Life (QoL) is of growing interest in schizophrenia research, little is known about putative causal determinants of this multidimensional construct. The present study explored the utility of objective indicators, psychopathological symptoms and psychosocial concepts drawn from empirical findings in community samples and the vulnerability-stress-coping model of schizophrenia for predicting general subjective QoL in post acute patients with schizophrenia. The analyses were based on cross-sectional data from 66 post acute patients with schizophrenia.
