Rapid thermal responses and thermal tolerance in adult codling moth Cydia pomonella (Lepidoptera: Tortricidae)
In order to preserve key activities or improve survival, insects facing variable and unfavourable thermal environments may employ physiological adjustments on a daily basis. Here, we investigate the survival of laboratory-reared ...
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+ ...
A survey of the prevalence of blowfly strike and the control measures used in the Rûens area of the Western Cape Province of South Africa
Blowfly strike and the methods used to combat blowfly strike were recorded on 33 properties in the Rûens area of South Africa during 2003/2004. Data were recorded on Merino and Dohne Merino hoggets (n = 4951) with at least ...
Evaluation of the Xpert MTB/RIF assay for the diagnosis of pulmonary tuberculosis in a high HIV prevalence setting
Rationale: Xpert MTB/RIF is a novel automated molecular diagnostic recently endorsed by the World Health Organization. However, performance-related data from high HIV prevalence settings are limited. Objectives: The impact ...
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. ...
