Relatively higher norms of blood flow velocity of major intracranial arteries in North-West Iran
<p>Abstract</p> <p>Background</p> <p>Transcranial Doppler (TCD) is a noninvasive, less expensive and harmless hemodynamic study of main intracranial arteries. The aim of this study was to assess normal population values of cerebral blood flow velocity and its variation over age and gender in a given population.</p> <p>Findings</p> <p>Eighty healthy volunteers including 40 people with an age range of 25-40 years (group1) and 40 persons with an age range of 41-55 years (group2) were studied. In each group 20 males and 20 females were enrolled. Peak systolic, end diastolic and mean velocities of nine main intracranial arteries were determined using TCD. Mean age of the studied volunteers was 31.6 ± 4.50 years in group one and 47.2 ± 4.3 years in group two. Mean age among males was 40 years and among females it was 39. Mean blood flow velocity in middle, anterior and posterior cerebral arteries, vertebral and basilar arteries was 60 ± 8, 52 ± 9, 42 ± 6, 39 ± 8 and 48 ± 8 cm/sec respectively. Cerebral blood flow velocities among females were relatively higher than males. Cerebral blood flow velocity of left side was relatively higher than right side.</p> <p>Conclusion</p> <p>Compared to previous studies, cerebral blood flow velocity in this population was relatively higher.</p

Etudes précliniques de candidats vaccins contre le paludisme (analyses immuno-épidémiologiques et validation d'un test fonctionnel de chimiluminescence)
Un vaccin contre Plasmodium falciparum est une grande priorité. Il est difficile de tester les candidats vaccins en essai clinique, et sans un bon modèle animal, des tests fonctionnels d anticorps in vitro sont nécessaires pour choisir les meilleurs candidats. Ce travail décrit un test mesurant l activation des neutrophiles (poussée respiratoire) et la phagocytose des mérozoïtes en présence d anticorps anti-mérozoïte, par chimiluminescence. Ce test est reproductible et relié à la protection clinique en zone d endémie. Les anticorps spécifiques de PfMSP1p19 et PfMSP4p20 exprimé en baculovirus sont fonctionnels dans ce test. Avec une reproductibilité confirmée ailleurs, il pourrait devenir un outil de référence. Une autre approche immuno-épidémiologique démontre une corrélation entre le taux d anticorps anti-PfMSP1p19 ou anti-PfMSP5 et la protection clinique.PARIS-BIUSJ-Thèses (751052125) / SudocPARIS-BIUSJ-Physique recherche (751052113) / SudocSudocFranceF
Honeybee health in Africa—a review
Honeybee (Apis mellifera L.) pathogens and parasites and the negative effects thereof on honeybee
populations remain an issue of public concern and the subject of active research. Africa with its high genetic
diversity of honeybee sub-species and large wild population is also exposed to various factors responsible for colony
losses in other parts of the world. Apart from the current American foulbrood epidemic in theWestern Cape of South
Africa, no large-scale colony losses have been reported elsewhere on the continent. We discuss the presence of
pathogens, parasites, pests and predators of African honeybees as well as the threats they face in relation to habitat
changes arising from the impact of increased human populations. In addition, we discuss current efforts aimed at
protecting and promoting the health of African honeybees.SouthAfrican National Research Foundation (NRF) and the University of Pretoria.http://link.springer.com/journal/135922017-05-31hb2016Zoology and Entomolog
