In most animals, the survival and reproductive success of males and females is linked to their size. The ability of individuals to control environmental influences on size will therefore have consequences for their fitness. In eusocial insects, individual males and reproductive females do not have to forage for themselves or control their local environment. Instead, they are reared by nonreproductive siblings (workers) inside colonies. Workers should benefit from controlling the size of sexuals because these sexuals are usually the only means for workers to transmit their genes to future generations. Nevertheless, considerable intraspecific variation exists around mean sexual size in social hymenopterans, even in species with monomorphic sexuals. This variation could result from genetic influences on sexual size, for instance sexuals may be selected to not agree to worker interests, or be due to strong, unpredictable environmental conditions constraining the efforts of workers to control sexual size. In a study that is the first of its kind I investigated genetic and environmental components of sexual body size variation in the ant Lasius niger, examining sexuals from wild colonies with one or several fathers (paternity levels established through microsatellite DNA offspring analysis). Evidence was found for a genetic component of size (broad-sense heritability of up to 42%) but strong common-colony effects (among-colony variation in food availability or in worker capacities to restrain sexual selfishness) also increased the size differences among colonies. Workers thus seem to only have partial-control over sexual size, but may be doing the best of a bad job.

Background: Community acceptance of Traditional birth attendants (TBAs) as professional birth attendant was reported as one of the bottlenecks that has been hindering facility childbirth care service use. Hence, the World Health Organization (WHO) recommended that all childbirths needed to be attended by professional skilled attendants who at least possessed midwifery skill through the safe motherhood initiative. However, many births in developing countries have been being attended by Traditional birth attendants (TBAs) mainly due to pregnant women and community acceptance for TBAs as sole birth attendants.

Sexual size dimorphism (SSD) is highly prevalent in nature. Several hypotheses aim to explain its evolution including sexual selection, differential equilibrium and ecological niche divergence. Disentangling the causal mechanism behind the evolution of SSD is challenging, as selection arising from multiple pressures on fitness may act simultaneously to generate observed patterns.

Summary: Paediatric pituitary adenomas are rare in children and adolescents and differ from adults in both clinical presentation and management. We present the case of a 14-year-old female with primary amenorrhoea secondary to a macroprolactinoma, showing a modest radiological and biochemical response to dopamine agonist (DA) therapy. Despite a 10-month duration of increasing DA therapy, initial symptoms of primary amenorrhoea and hyperprolactinaemia persisted, with new symptoms of weight gain, lethargy and low mood.

, the earliest known ceratopsian, is represented by dozens of specimens of different sizes collected from the Upper Jurassic of the Junggar Basin, northwestern China. Here, we present the first comprehensive study on the bone histology of based on ten specimens varying in size. Four ontogenetic stages are recognized: early juvenile, late juvenile, subadult, and adult.

Background: Sexual dysfunction (SD) due to Selective Serotonin Reuptake Inhibitors (SSRI) use is a common condition encountered by psychiatrists and its etiology has not been fully elucidated.
Aim: To determine the relationship between alpha Melanocyte Stimulating Hormone (α-MSH) and Melanocortin-4 receptor (MCR4) levels and sexual function levels of patients with and without SSRI related SD and control group and to examine whether α-MSH and MCR4 play a role in the etiology of SSRI related SD.
Methods: A total of 92 patients and 49 healthy volunteers who applied to psychiatry outpatient clinic were included in the study.
