OBJECTIVE To assess the concentration of progesterone (PRs) and oestrogen (ORs) receptors of myometrium of full-term pregnant women in the myometrium of lower segment of the uterus in relationship with presence or absence of labour. METHODS This was a cross-sectional prospective study with 21 pregnant women, being 6 in labour (Group I) and 15 without labour (Group II). The biopsy of myometriu...

To the Editor: Olfactory reference syndrome (ORS) is a condition characterized by concerns about perceived body odor, which may lead to repetitive behaviors to diminish the odor, as well as to avoidance of social interactions.1,2 A range of other terms describing olfactory reference symptomatology has appeared in the literature; for example, based on the observation that it involves a single be...

BACKGROUND Oral rehydration solutions (ORS) for the treatment of acute diarrhea remain an underutilized therapy in the United States, despite multiple clinical trials confirming their efficacy and safety. Economic barriers to their use have been identified. OBJECTIVE To determine whether providing ORS to patients at the time of their office visit for acute diarrhea can increase ORS utilizatio...

Herbivore-induced plant volatiles (HIPVs) play a key role in the interactions between plants and herbivorous insects, as HIPVs can promote or deter insects’ behavior. While aphids are common serious phloem-feeding pests farmland ecosystems, little is known about how use their sensitive olfactory system to detect HIPVs. In this study, antennal transcriptomes of aphid species Megoura crassicauda ...

Tsetse flies use olfactory and gustatory responses, through odorant and gustatory receptors (ORs and GRs), to interact with their environment. Glossina morsitans morsitans genome ORs and GRs were annotated using homologs of these genes in Drosophila melanogaster and an ab initio approach based on OR and GR specific motifs in G. m. morsitans gene models coupled to gene ontology (GO). Phylogeneti...

BACKGROUND In Bangladesh, pharmacy-purchased oral rehydration solution (ORS) is often used to treat diarrhea, including cholera. Over-the-counter sales have been used for epidemiologic surveillance in the past, but rarely, if ever, in low-income countries. With few early indicators for cholera outbreaks in endemic areas, diarrhea-related product sales may serve as a useful surveillance tool. ...
