traumatic neuronal injury in vitro is attenuated by nmda antagonists.pure traumatic neuronal injury was modeled in dispersed neocortical cell cultures derived from fetal mice. a plastic stylet was used to tear the neuronal and glial cell layer; medium oxygen content, ph, and glucose remained unchanged. adjacent to this local disruption, many neurons developed acute swelling and went on to degenerate over the next day, but glia were relatively spared. if the same mechanical insult was delivered in the presence of the n-methyl-d-aspartate (nmda) antagonists dextror ...20082576374
risk factors for late relapse in male and female ex-smokers.three hundred twenty-nine ex-smokers (149 males and 180 females) who had maintained abstinence for at least 3 months prior to intake were followed for a period of 1 year to ascertain individual characteristics from cognitive, behavioral, environmental, and health domains that were predictive of later relapse. multiple logistic regression analysis revealed significant associations between relapse, family history, and stress variables in males and between relapse, family history, stress, pre- and ...20113177069

[significance of sudden infant death (sids) for otorhinolaryngology].the high frequency of proven extensive infection in the upper respiratory tract, particularly the nose and pharynx, of infants with sids, suggests that the latter may be due to upper airway obstruction. in view of the particular vulnerability of the early infant, the widespread term "common cold" does not seem justified. the constant incidence of sids should stimulate study of the extension and effects of infection of the upper respiratory tract, including careful investigation, follow up and ad ...20133679898

ethnic differences in congenital malformations.perinatal deaths and major lethal and non-lethal congenital malformations occurring in this hospital from 1979-82 inclusive were related to the ethnic group of the 15 438 mothers. the highest crude perinatal mortality rates occurred in indian and pakistani populations (18.3 per 1000 and 24.1 per 1000 respectively). the highest incidence of congenital abnormality also occurred in these groups (13.3 per 1000 and 12.8 per 1000 respectively), but there was considerable variation in the distribution ...20144051543

airborne mineral fibre concentrations in an urban area near an asbestos-cement plant.ambient air concentrations of asbestos and total mineral fibres were measured during the period june-july 1985 at several locations near a large asbestos-cement factory located in the proximity of a northern italian town. measurements of the number and type of fibres were made by means of analytical scanning electron microscopy and energy-dispersive x-ray analysis (sem-edxa), essentially according to the rtm2 reference method of the asbestos international association. total mineral fibre concent ...20092744833
relationship between severity and clinical importance of symptoms in osteoarthritis.seventeen patients with primary osteoarthritis of the knee were evaluated with respect to the severity and clinical importance of pain, stiffness and physical function during the conduct of a double-blind randomized controlled trial of flurbiprofen sr versus diclofenac sodium sr using the womac osteoarthritis index. mean importance scores were similar for items within the same dimension as well as between items in different dimensions. in general, low levels of correlation were noted between the ...20071914413
[the effect of indomethacin and leukinferon on the thromboxane b2 level in the blood plasma of patients with endometrial cancer in the perioperative period].the paper discusses the effect of indomethacin, leukinferon as well as their combined effect on blood thromboxane b2 (txb2) level in 40 endometrial cancer patients in the perioperative period. perioperative treatment with indomethacin was followed by a significant decrease in blood txb2 level before surgery and in the postoperative period. treatment with leukinferon exerted similar effect which, however, was less pronounced than that of indomethacin. the effect was most apparent when the two dru ...20001300754
computer-specific spectacle lens design preference of presbyopic operators.twenty-nine presbyopic subjects who spent at least 20 hours a week at a video display terminal compared a progressive addition lens designed for this function, with another commonly prescribed task-specific lens. each of the paired lens types was worn for 4 weeks and then compared directly for 1 week. a statistically significant (p < .05) portion of the subjects (76%) preferred the task-specific lenses overall. it also was preferred more frequently for each feature compared, although the differe ...20061403191

major histocompatibility complex class i-restricted activation of cloned t cells by a soluble protein in the absence of accessory cells.a t-cell clone, 10bk.1, was established from the draining lymph nodes of (b10 x mice immunized with ovalbumin (ova) according to standard protocols. upon coculture with the antigen, 10bk.1 cells reacted by production of lymphokines and by proliferation despite the absence of additional antigen-presenting cells. these t cells do not express major histocompatibility complex (mhc) class ii molecules on the cell surface as assessed on the basis of several criteria: by cytofluorometric anal ...20092784568
[mesotheliomas among mechanics of the railways in italy: a current problem].asbestos has been used on rolling stock of the italian railways since the 1940's. from the 1950's to the 1970's it was used on a massive scale for the insulation of passenger carriages (up to more than 800 kg per carriage). about 10 years ago, a programme was began to remove asbestos from rolling stock and replace it with glass fibre. we must consider as exposed to the carcinogenic effects of asbestos all mechanics who, during the past years, worked at the major repair workshops (mrw), at the lo ...20092770615
diagnosis and treatment of attention deficit disorder in two general hospital two clinics in military general hospitals, the charts of all children with a presumptive diagnosis of attention deficit disorder who were prescribed psychostimulants (n = 68) were audited to assess the quality of the primary physicians' evaluation and treatment. the audit instrument, constructed by a multidisciplinary team, indicated high interrater reliabilities, high face and concurrent validity, and moderate internal consistency. the audit found that only 51.5 percent of the children being ...20092777226
