Prevalence of Non-communicable Diseases and its Awareness among Inhabitants of Sokoto Metropolis: Outcome of a Screening Program for Hypertension, Obesity, Diabetes Mellitus and Overt proteinuria
Introduction: Developing countries confront double jeopardy of prevalent infectious disease and increasing Non-Communicable Diseases (NCD) with imminent projected epidemic proportions. Nigeria has witnessed tremendous socio-economic changes and rural to urban migration culminating in emergence of NCD. The impact of these diseases on the lives of people is enormous when measured in terms of outcomes. We initiated a screening program among inhabitants of Sokoto metropolis in an attempt to unravel the prevalence and pattern of NCD.Methods: This is a descriptive cross sectional study involving 535 participants who were randomly selected during World Kidney Day Screening in Sokoto. Health promotion talk was organized for the participants before commencing the screening. We took anthropometric measurements and calculated body mass index (BMI) and waist/hip ratio for all individuals. We also checked blood pressure and blood glucose levels and performed urinalysis for all participants.Results: There were 535 participants including 332 males and 203 females with a mean age of 37±17 years. Over-weight, obesity and morbid obesity were found in 12.3%, 6.7% and 0.9% of participants respectively. About 11% had waist/hip ratio greater than 1. The prevalence of pre-hypertension and hypertension was 8.5% and 30.2% respectively. Elevated random blood glucose levels were found in 6% of participants while 17.9% had at least 1+ of proteinuria in urinalysis.Conclusion: Non-communicable diseases are common in our environment and the level of awareness is low. Regular health education and screening programs are necessary in order to reduce the menace.Key words: Non- communicable disease; Prevalence; Screening; Sokot
Candidate chemoreceptor subfamilies differentially expressed in the chemosensory organs of the mollusc Aplysia
<p>Abstract</p> <p>Background</p> <p>Marine molluscs, as is the case with most aquatic animals, rely heavily on olfactory cues for survival. In the mollusc <it>Aplysia californica</it>, mate-attraction is mediated by a blend of water-borne protein pheromones that are detected by sensory structures called rhinophores. The expression of G protein and phospholipase C signaling molecules in this organ is consistent with chemosensory detection being via a G-protein-coupled signaling mechanism.</p> <p>Results</p> <p>Here we show that novel multi-transmembrane proteins with similarity to rhodopsin G-protein coupled receptors are expressed in sensory epithelia microdissected from the <it>Aplysia </it>rhinophore. Analysis of the <it>A. californica </it>genome reveals that these are part of larger multigene families that possess features found in metazoan chemosensory receptor families (that is, these families chiefly consist of single exon genes that are clustered in the genome). Phylogenetic analyses show that the novel <it>Aplysia </it>G-protein coupled receptor-like proteins represent three distinct monophyletic subfamilies. Representatives of each subfamily are restricted to or differentially expressed in the rhinophore and oral tentacles, suggesting that they encode functional chemoreceptors and that these olfactory organs sense different chemicals. Those expressed in rhinophores may sense water-borne pheromones. Secondary signaling component proteins Gα<sub>q</sub>, Gα<sub>i</sub>, and Gα<sub>o </sub>are also expressed in the rhinophore sensory epithelium.</p> <p>Conclusion</p> <p>The novel rhodopsin G-protein coupled receptor-like gene subfamilies identified here do not have closely related identifiable orthologs in other metazoans, suggesting that they arose by a lineage-specific expansion as has been observed in chemosensory receptor families in other bilaterians. These candidate chemosensory receptors are expressed and often restricted to rhinophores and oral tentacles, lending support to the notion that water-borne chemical detection in <it>Aplysia </it>involves species- or lineage-specific families of chemosensory receptors.</p
Analysis of Male Pheromones That Accelerate Female Reproductive Organ Development
Male odors can influence a female's reproductive physiology. In the mouse, the odor of male urine results in an early onset of female puberty. Several volatile and protein pheromones have previously been reported to each account for this bioactivity. Here we bioassay inbred BALB/cJ females to study pheromone-accelerated uterine growth, a developmental hallmark of puberty. We evaluate the response of wild-type and mutant mice lacking a specialized sensory transduction channel, TrpC2, and find TrpC2 function to be necessary for pheromone-mediated uterine growth. We analyze the relative effectiveness of pheromones previously identified to accelerate puberty through direct bioassay and find none to significantly accelerate uterine growth in BALB/cJ females. Complementary to this analysis, we have devised a strategy of partial purification of the uterine growth bioactivity from male urine and applied it to purify bioactivity from three different laboratory strains. The biochemical characteristics of the active fraction of all three strains are inconsistent with that of previously known pheromones. When directly analyzed, we are unable to detect previously known pheromones in urine fractions that generate uterine growth. Our analysis indicates that pheromones emitted by males to advance female puberty remain to be identified

Hemodialysis performance and outcomes among end stage renal disease patients from Sokoto, North-Western Nigeria
The cost of managing end stage renal disease (ESRD) is prohibitive in Nigeria and the burden is solely borne by patients and their relatives. Despite increasing number of dialysis centers in urban areas, actual utilization of such facilities is very low. It is unclear if the outcomes of these patients have improved in recent times. We evaluated pattern of hemodialysis (HD) performance and outcome among ESRD patients. A 5-year prospective cross-sectional study of all ESRD patients on HD was undertaken. The final outcomes included duration on maintenance dialysis, death from inability to sustain dialysis, absconded, confirmed deaths within or outside health facility or referral for kidney transplant. A total of 540 (54%) of 976 cases of ESRD commenced HD, out of which 7 (1.3%) eventually had live-related kidney transplant in India. The male to female ratio was 2:1 with male and female mean ages of 43 ± 17 and 36 ± 16 years respectively. There was a progressive annual increase in the number of ESRD patients. The commonest underlying renal disorder was chronic glomerulonephritis. The mean HD session duration was 8.11 ± 5.4 hours, while the mean duration of stay on HD was 8.72 ± 1.0 weeks. In conclusion, ESRD is common and is being increasingly recognized. Financial constraint and late presentation are major contributory factors to poor outcomes despite the widespread availability of HD facilities. Therefore, effort should be geared towards aggressive strategies for early detection and treatment. Government commitment in terms of funding and/or subsidy for patient with ESRD is advocated

The full repertoire of Drosophila gustatory receptors for detecting an aversive compound
The ability to detect toxic compounds in foods is essential for animal survival. However, the minimal subunit composition of gustatory receptors required for sensing aversive chemicals in Drosophila is unknown. Here we report that three gustatory receptors, GR8a, GR66a and GR98b function together in the detection of L-canavanine, a plant-derived insecticide. Ectopic co-expression of Gr8a and Gr98b in Gr66a-expressing, bitter-sensing gustatory receptor neurons (GRNs) confers responsiveness to L-canavanine. Furthermore, misexpression of all three Grs enables salt- or sweet-sensing GRNs to respond to L-canavanine. Introduction of these Grs in sweet-sensing GRNs switches L-canavanine from an aversive to an attractive compound. Co-expression of GR8a, GR66a and GR98b in Drosophila S2 cells induces an L-canavanine-activated nonselective cation conductance. We conclude that three GRs collaborate to produce a functional L-canavanine receptor. Thus, our results clarify the full se
