Exploring opportunities to enhance effectiveness of mobile health and nutrition strategy for providing health and nutrition services amongst pastoralists in Somali region, Ethiopia.

Background: The health system in Ethiopia's Somali Region is weak with limited number of health facilities with more than 60% of the population living more than 5 km to the nearest health facilities. The deployment of mobile health and nutrition teams has played critical role in providing essential health and nutrition services.

Aim: This study aimed to assess the effectiveness of the mobile health and nutrition strategy in providing health and nutrition services in the targeted woredas (districts).

Preferential Mapping of Sex-Biased Differentially-Expressed Genes of Larvae to the Sex-Determining Region of Flathead Grey Mullet ().

Flathead gray mullet () is a cosmopolitan mugilid species popular in fishery and aquaculture with an economic preference for all-female population. However, it displays neither sexual dimorphisms nor heteromorphic sex chromosomes. We have previously presented a microsatellite-based linkage map for this species locating a single sex determination region (SDR) on linkage group 9 (LG9) with evidence for XX/XY sex determination (SD) mechanism.

The effect of algal turbidity on larval performance and the ontogeny of digestive enzymes in the grey mullet (Mugil cephalus).

A study comprised of two trials determined the effects of water turbidity produced by live microalgae and inert clay particles on the larval rearing of grey mullet (Mugil cephalus). Trial 1 evaluated the effect of microalgae produced water turbidity on grey mullet larval performance and digestive tract (DT) enzyme ontogeny. Two microalgae (Nannochloropsis oculata and Isochrysis galbana) water turbidity levels (0.

Junction-less phototransistor with nanowire channels, a modeling study.

We propose a new nanowire based, junction-less phototransistor, that consists of a channel with both wide and narrow regions to ensure efficient light absorption and low dark current, respectively. While the light is absorbed in the wide region, the narrow region allows for ease of band engineering. We also find that a nanowire in the source can further boost the optical gain.

The effects of arachidonic acid on the endocrine and osmoregulatory response of tilapia (Oreochromis mossambicus) acclimated to seawater and subjected to confinement stress.

In previous studies in freshwater tilapia (Oreochromis mossambicus), dietary supplementation with arachidonic acid (ArA; 20:4n - 6) had considerable, opposing effects on the main ion-transporting enzyme Na(+)/K(+)-ATPase in gills and kidneys and changed the release of osmoregulatory hormones, such as cortisol. The present study was performed to assess the influence of dietary ArA on (1) the osmoregulatory capacity of tilapia acclimated to seawater (SW) (34‰) and (2) the osmoregulatory imbalance associated with acute stress. The increased ambient salinity was associated with significant alterations in the tissue fatty acid composition, particularly the n - 6 polyunsaturated fatty acids (PUFAs).

Arachidonic acid reduces the stress response of gilthead seabream Sparus aurata L.

In this study the influence of the dietary level of the fatty acid arachidonic acid (ArA, 20:4n-6) was determined on the acute stress response and osmoregulation of adult gilthead seabream Sparus aurata L. Seabream were fed a diet containing either 0.9% or 2.

Evaluation of a problem-based learning workshop using pre- and post-test objective structured clinical examinations and standardized patients.

Background: Osteoporosis is a health care issue in which family physicians play a major role. Although awareness of osteoporosis is high, recent studies suggest that application of recent advances in its treatment to the clinical setting may be low. We have developed a problem-based learning intervention for osteoporosis in which paired rheumatologists and family physicians developed nine problem-solving clinical scenarios.

Case studies in osteoporosis: a problem based learning intervention for family physicians.

Objective: To develop and evaluate a practice based small group (PBSG) learning intervention on osteoporosis for primary care physicians.

Methods: A needs assessment on osteoporosis was performed and objectives for a continuing medical education (CME) program developed by an interdisciplinary advisory committee. Nine clinical cases were developed for evaluation by CME participants with a trained facilitator and content expert using the PBSG format.
