Effects of flow rate and temperature on cyclic gas exchange in tsetse flies (Diptera, Glossinidae)
Air flow rates may confound the investigation and classification of insect gas exchange patterns. Here we report the effects of flow rates (50, 100, 200, 400 ml min-1) on gas exchange patterns in wild-caught Glossina ...
Control of copula duration and sperm storage by female Queensland fruit flies
Copula duration and sperm storage patterns can directly or indirectly affect fitness of male and female insects. Although both sexes have an interest in the outcome, research has tended to focus on males. To investigate ...

Long-term outcome of surgically managed necrotizing enterocolitis in a developing country
Necrotizing enterocolitis (NEC) is a serious condition with a high morbidity and mortality commonly affecting premature babies. Data for the impact of the longterm disease burden in developing countries are limited although ...
Cross-species chromosome painting in bats from Madagascar: The contribution of Myzopodidae to revealing ancestral syntenies in Chiroptera
The chiropteran fauna of Madagascar comprises eight of the 19 recognized families of bats, including the endemic Myzopodidae. While recent systematic studies of Malagasy bats have contributed to our understanding of the ...
Effect of HIV infection status and Anti-retroviral treatment on quantitative and qualitative antibody responses to pneumococcal conjugate vaccine in infants
Serotype-specific antibody concentration and opsonophagocytic activity (OPA) were evaluated after 3 doses of pneumococcal conjugate vaccine. Groups included human immunodeficiency virus (HIV)-positive infants with CD4+ ...
Fetal general movements and brain sonography in a population at risk for preterm birth
Background: General movements (GMs) assessed three months post term are related to brain injury and neurological outcome. Aims: To study GMs in fetuses and their predictive value for echogenicity changes in the fetal brain. ...
General movements in the perinatal period and its relation to echogenicity changes in the brain
Background: In preterm born infants abnormal general movements (GMs) generally normalize before three months post term, but may persist when perinatal brain injury is present. Aims: To assess the continuity of GM quality ...
Antiretroviral treatment for children with peripartum nevirapine exposure
Background: Single-dose nevirapine is the cornerstone of the regimen for prevention of mother-to-child transmission of human immunodeficiency virus (HIV) in resource-limited settings, but nevirapine frequently selects for ...
A novel sex determination system in a close relative of the house mouse
Therian mammals have an extremely conserved XX/XY sex determination system. A limited number of mammal species have, however, evolved to escape convention and present aberrant sex chromosome complements. In this study, we ...
