Multimodal Advertisement of Pregnancy in Free-Ranging Female Japanese Macaques (Macaca fuscata)

The role of multiple sexual signals in indicating the timing of female ovulation, and discrimination of this timing by males, has been particularly well studied among primates. However the exhibition of pregnancy signals, and how such signals might modulate male post-conception mating decisions, is still poorly understood. Here we aimed to determine if Japanese macaque males use...

Aquaporin-4 expression in distal myopathy with rimmed vacuoles

Background Distal myopathy with rimmed vacuoles/hereditary inclusion body myopathy is clinically characterized by the early involvement of distal leg muscles. The striking pathological features of the myopathy are muscle fibers with rimmed vacuoles. To date, the role of aquaporin-4 water channel in distal myopathy with rimmed vacuoles/hereditary inclusion body myopathy has not...

Monkeys in the Middle: Parasite Transmission through the Social Network of a Wild Primate

In wildlife populations, group-living is thought to increase the probability of parasite transmission because contact rates increase at high host densities. Physical contact, such as social grooming, is an important component of group structure, but it can also increase the risk of exposure to infection for individuals because it provides a mechanism for transmission of...

Is antipsychotic polypharmacy associated with metabolic syndrome even after adjustment for lifestyle effects?: a cross-sectional study

Background Although the validity and safety of antipsychotic polypharmacy remains unclear, it is commonplace in the treatment of schizophrenia. This study aimed to investigate the degree that antipsychotic polypharmacy contributed to metabolic syndrome in outpatients with schizophrenia, after adjustment for the effects of lifestyle. Methods A cross-sectional survey was carried...

Induction of Glomerular Lesions in the Kidneys of Mice Infected with Vero Toxin-Producing Eschevichia coli by Lipopolysaccharide Injection

Lipopolysaccharide was injected into germ-free mice after they had been infected with Vero toxin-producing Escherichia coli. Microscopic examination of the kidneys of these mice showed an increased number of mesangial cells and a vacancy in the glomerular capillary lumen. A significant elevation in the expression level of interferon (IFN)-γ in the kidney may have played a key...
