‘Disability and HIV in Africa: Breaking the barriers to sexual health care’

Three decades in to the HIV pandemic, the issues affecting people with disabilities remains less known. Increasing attention has been given to this overlooked population when it comes to HIV prevention, treatment and care. This is related to the significant unmet sexual and reproductive health care needs facing people with disabilities worldwide. This article discusses the barriers to sexual health for people with disabilities in Africa, and presents an argument about how mainstream HIV prevention work and research does not adequately attend to the sorts of systemic barriers that exclude people with disabilities, which a more targeted, and critical approach could.

Sexual dimorphism in relation to adipose tissue and intrahepatocellular lipid deposition in early infancy

Sexual dimorphism in adiposity is well described in adults, but the age at which differences first manifest is uncertain. Using a prospective cohort, we describe longitudinal changes in directly measured adiposity and intrahepatocellular lipid (IHCL) in relation to sex in healthy term infants. At median ages of 13 and 63 days, infants underwent quantification of adipose tissue depots by whole-body magnetic resonance imaging and measurement of IHCL by in vivo proton magnetic resonance spectroscopy. Longitudinal data were obtained from 70 infants (40 boys and 30 girls). In the neonatal period girls are more adipose in relation to body size than boys. At follow-up (median age 63 days), girls remained significantly more adipose. The greater relative adiposity that characterises girls is explained by more subcutaneous adipose tissue and this becomes increasingly apparent by follow-up. No significant sex differences were seen in IHCL. Sex-specific differences in infant adipose tissue distribution are in keeping with those described in later life, and suggest that sexual dimorphism in adiposity is established in early infancy.

Sexual functioning in people with stable chronic diseases

Backgound - In developed countries people are living longer and the incidence of chronic disease is increasing. Chronic disease and its treatments can have a negative impact on sexual functioning and sexual satisfaction. Aim of study - To explore and to compare sexual function and sexual satisfaction in people with stable chronic diseases.

An integrated approach to Physcomitrella patens transcriptomics reveals importantclues of the evolutionary development of plant organs and sexual reproduction

Land plant evolution required the generation of a new body plan that could resist the harsher and fluctuating environmental conditions found outside of aquatic environments. Unraveling the genetic basis of plant developmental innovations is not only revealing in terms of an evolutionary point of view, but it is also important for understanding the emergence of agronomically important traits. Comparative genetic studies between basal and modern land plants, both at the genome and trancriptome levels, can help in the generation of hypotheses related to the genetic basis of plant evolutionary development.(...)

Sexual dimorphism in resource acquisition and deployment: both size and timing matter.

Background and Aims The males and females of many dioecious plant species differ from one another in important life-history traits, such as their size. If male and female reproductive functions draw on different resources, for example, one should expect males and females to display different allocation strategies as they grow. Importantly, these strategies may differ not only between the two sexes, but also between plants of different age and therefore size. Results are presented from an experiment that asks whether males and females of Mercurialis annua, an annual plant with indeterminate growth, differ over time in their allocation of two potentially limiting resources (carbon and nitrogen) to vegetative (below-and above-ground) and reproductive tissues.Methods Comparisons were made of the temporal patterns of biomass allocation to shoots, roots and reproduction and the nitrogen content in the leaves between the sexes of M. annua by harvesting plants of each sex after growth over different periods of time.Key Results and Conclusions Males and females differed in their temporal patterns of allocation. Males allocated more to reproduction than females at early stages, but this trend was reversed at later stages. Importantly, males allocated proportionally more of their biomass towards roots at later stages, but the roots of females were larger in absolute terms. The study points to the important role played by both the timing of resource deployment and the relative versus absolute sizes of the sinks and sources in sexual dimorphism of an annual plant.

Desarrollo sexual del paiche (arapaima gigas) en las zonas reservadas del estado (ríos Pacaya y Samiria) 1971 - 1975

Desarrolla los datos registrados en la Reserva Nacional Pacaya - Samiria, de noviembre de 1971 a noviembre de 1975, efectuado con 697 paiches hembras; donde determinaron el ciclo de desove y la longitud que alcanza el paiche en su primera madurez sexual.

Reporte de datos de madurez sexual de la anchoveta peruana (engraulis ringens) durante el periodo 1961 - 1987

Se presentan datos de madurez sexual promedio mensual de la anchoveta peruana, Engraulis ringens por longitudes y sexos, para las Regiones Norte (06°-10°S), Centro (10°-14° S) y Sur (14°-18°20 ' S) para el período 1961-87. Estos se obtuvieron usando los datos de madurez sexual colectados macroscópicamente de ejemplares procedentes de los desembarques a lo largo del litoral peruano.

Efecto de la proporción sexual, densidad y edad de los reproductores en la producción de semilla de Tilapia nilotica (Pisces, Cichlidae)

En el Laboratorio de Huachipa del Instituto del Mar del Perú, en el período comprendido entre octubre de 1980 y agosto de 1982, se realizaron varios experimentos a fin de determinar el efecto del tipo de estanque, densidad de carga y calidad y cantidad de fertilizante en el crecimiento y la producción de Tilapia nilotica. Estos experimentos arrojaron una diferencia no significativa entre los tratamientos, por lo cual se halló una cifra general promedio de crecimiento y producción que permitió su comparación con las cifras de producción obtenidas en otras áreas del mundo, un peso individual promedio de 203.4 g, una producción total de 2,038 Kg/ha/272 días, y una producción neta de 5.6 Kg/ha/día. Cifras que quedan dentro del rango reportado por el ICA (International Center for Aquaculture) para clima templado; similares a las obtenidas en países de Europa Central y la China, y notablemente bajas comparadas con los 20 Kg/ha/día producidos en Israel. Se identifican la mala condición de los estanques utilizados, la baja densidad de carga aplicada, la baja calidad del fertilizante y el clima de la zona, específicamente la presencia de nubosidad, como los factores de mayor incidencia en los resultados poco satisfactorios.
