background: anti-phospholipids syndrome (aps) is considered a non inflammatory auto-immune disease with a significant thrombophilic risk with varied clinical manifestations. the purpose of the current study was to investigate the frequency of thrombotic and non-thrombotic events in patients with aps. methods: in this retrospective study, 102 definite aps subjects were recruited (2007-2011) at a...

BACKGROUND Exposure to bright light such as sunlight elicits a sneeze or prickling sensation in about one of every four individuals. This study presents the first scientific examination of this phenomenon, called 'the photic sneeze reflex'. METHODOLOGY AND PRINCIPAL FINDINGS In the present experiment, 'photic sneezers' and controls were exposed to a standard checkerboard stimulus (block 1) an...

analyses. Contrary to Abernathy's assertion, smoking is quite unlikely to account for the increased mortality in heavier people because in virtually all studies heavier people have smoked less than thin people. Although Abemathy would prefer to discard height and weight tables, the excess mortality,and morbidity associated.with overweight is not eliminated just by dismissing the tables. We conc...

Most digital designs inherently possess asynchronous behaviors of some kind. While the SystemVerilog assertion (SVA) language offers some asynchronous controls like disable iff, writing concurrent assertions that accurately describe asynchronous behavior is not so straightforward. SVA properties require a clocking event, making them innately synchronous. When describing asynchronous behavior, t...

Plastic bronchitis (PB) refers to the presence of inspissated Bronchial casts (BC) is uncommon in children.Our case presented with subcutaneous emphysema as the dominant manifestation and was suspected to have foreign body in airway, but bronchoscopy revealed a bronchial cast. Subcutaneous emphysema as the initial/sole manifestation of plastic bronchitis is very rare in children.

purpose: to determine the prevalence of ocular involvement in patients with tuberculosis (tb) infection. methods: all patients with a new diagnosis of tb who were referred to zahedan tuberculosis center underwent a complete ophthalmic examination. any cases of known ophthalmic disease or previous ocular involvement were excluded from the study. prevalence of ocular involvement with 95% confiden...

Many studies have focused on the effects of anthropogenic noise on animal communication, but only a few have looked at its effect on other behavioural systems. We designed a playback experiment to test the effect of noise on predation risk assessment. We found that in response to boat motor playback, Caribbean hermit crabs (Coenobita clypeatus) allowed a simulated predator to approach closer be...

Paradoxical manifestation is worsening of pre-existing tuberculous lesion or appearance of new lesions in patients whose condition initially improved with antituberculous treatment. Our hypothesis was that paradoxical manifestation in non-HIV tuberculous meningitis (TBM) patients was underestimated and this could contribute to patients' prognosis. This was the first systemic study of paradoxica...

background: one-third of the world’s population is currently infected by tubercle bacillus. this study was performed to evaluate epidemiological and clinical aspects of confirmed cases of tuberculosis infections in a seven-year time period, between years of 2002 to 2008, in the city of hamadan, west of iran. materials and methods: in this descriptive retrospective study, medical records of 375 ...
