Many cell division processes have been conserved throughout evolution and are being revealed by studies on model organisms such as bacteria, yeasts, and protozoa. Cellular membrane constriction is one of these processes, observed almost universally during cell division. It happens similarly in all organisms through a mechanical pathway synchronized with the sequence of cytokinetic events in the...

ObjectivesTo discover the prevalence of endotracheal tube (ETT) constriction and rostral caudal mispositioning in anaesthetised cats dogs, to identify associated risk factors.Study DesignRetrospective analysis.Animal populationA total 146 cats, 670 dogs.MethodsComputed tomography images head/neck/thorax from orotracheally intubated dogs were visually assessed for or ETT. If was present, measure...

Throughout organismal development, precise three-dimensional organization of tissues is required for proper tissue function. These three-dimensional forms are generated by coordinated cell shape changes that induce global tissue shape changes, such as the transformation of an epithelial sheet into a tube. A model for this transformation occurs early in Drosophila development where approximately...

1 of 3 DESCRIPTION A middle-aged hypertensive lady was admitted with progressive weight gain and generalised edema of 1-year duration. Examination revealed a raised jugular venous pressure, anasarca, atrial fi brillation and no signifi cant murmurs. Evaluation revealed mild anaemia with raised erythrocyte sedimentation rate. Chest radiograph and echocardiography revealed cardiomegaly, biatrial ...

ing was present. The last menstrual period had started 14 days previously. There was no history of nocturia, dysuria, frequency or backache. Irregular acquired dysmenorrhcea had been noted in the past. A similar attack had occurred two months previously on a train trip from Calcutta and lasted a few days. The patient had shortly afterwards a routine annual physical examination by another physic...

STUDY OBJECTIVE To determine the effects of hawthorn (Crataegus oxycantha) on left ventricular remodeling and function in pressure overload-induced heart failure in an animal model. DESIGN Randomized, parallel, dose-ranging animal study. SETTING University research facility. ANIMALS Seventy-four male Sprague-Dawley rats; 44 were included in the final analysis. INTERVENTION Rats underwen...

A patient with idiopathic pericardial effusion is reported. Patient developed transient constrictive hemodynamics which recovered with continued empirical use of antitubercular drugs and prednisolone.

Patients with congenital achromatopsia and congenital stationary night blindness have been known to show a transient pupillary constriction to darkness. We examined 50 normal subjects and 108 patients with retinal and optic nerve dysfunction to see if any had an initial pupillary constriction to darkness. We used a new infrared television apparatus. Four patients with congenital stationary nigh...

J. E. COTES Breathlessness is one of a number of symptoms which may limit exercise; it usually does so when the ventilation during exercise approaches a maximal value which is determined by interaction between the drive to respiration and the mechanical properties of the lung. Assessment is based in the first instance on the clinical interview and simple measurements of lung function. Depending...

conclusions cmr with stir sequences, free breathing sequences and late gadolinium imaging can prove extremely useful for diagnosing constrictive pericarditis. case presentation a 77-year-old man from a country with high incidence of tuberculosis presented with severe dyspnea. echocardiography revealed a small left ventricle with normal systolic and mildly impaired diastolic function. left heart...
