sympathetic uveitis after giant tear repair. | a 33-year-old hispanic man developed sympathetic ophthalmia 4.5 months after vitrectomy and repeat scleral buckling for a giant retinal tear in an aphakic previously traumatized eye. the patient had gray-white, subretinal nodules with characteristic changes of sympathetic uveitis detected by fluorescein angiography. the fluorescein angiographic and clinical findings revealed a dramatic response to steroid treatment: visual acuity returned to the previous 20/20 level within 5 weeks of therapy. | 1989 | 2772419 |
childhood obsessive compulsive disorder: a two-year prospective follow-up of a community sample. | a 2-year prospective follow-up of a community-based sample of adolescents previously diagnosed as having obsessive compulsive disorder (ocd) or "obsessive compulsive spectrum" disorder and a control sample was completed by clinicians experienced with ocd but blind to prior diagnosis. an initial diagnosis of ocd or "other psychiatric disorder with oc features" was most likely to predict a diagnosis of ocd at follow-up. subclinical ocd at baseline did not strongly predict continuing psychopatholog ... | 2009 | 2768147 |
tetrahydroaminoacridine and other allosteric antagonists of hippocampal m1 muscarine receptors. | tetrahydroaminoacridine (tha) and a variety of other nonclassical antagonists of muscarine receptors were studied for their ability to bind to primary and allosteric sites on muscarine receptors in rabbit hippocampal membranes. competition curves between 13 antagonists and 1 nm [3h]pirenzepine (kd = 3 nm) were simple mass action curves, but tha produced steeper curves, indicating positive cooperativity. nonetheless, tha inhibited the binding of low concentrations of [3h]pirenzepine, [3h]n-methyl ... | 1989 | 2725474 |
identification of gram-positive coccal and coccobacillary vancomycin-resistant bacteria. | a total of 84 of 150 vancomycin-resistant (defined as no inhibition of bacterial growth around a 30-micrograms vancomycin disk placed on 5% sheep blood-trypticase soy agar [bbl microbiology systems, cockeysville, md.]) bacteria were definitively identified by determining the phenotypic criteria. the identity of representatives was also confirmed by dna-dna hybridizations. the following strains were identified: 1 enterococcus faecium, 18 leuconostoc mesenteroides, 15 leuconostoc citreum, 9 leucon ... | 1989 | 2723037 |
studies on oxidized low density lipoproteins. controlled oxidation and a prostaglandin artifact. | low density lipoproteins (ldl), isolated by ultracentrifugal flotation, were oxidized (ldloxid) slowly during dialysis against 0.15 m nacl and subsequent incubation in 96% air-4% co2 at 37 degrees c. butylated hydroxytoluene prevented ldl oxidation. ldl preparations from different sera were oxidized at different rates and the degree of lipid peroxidation was controlled by varying the incubation time. mild oxidation did not alter the electrophoretic mobility of the ldloxid preparations. ldloxid c ... | 2009 | 2715720 |
pulmonary edema localized in the right upper lobe accompanying mitral regurgitation. | focal patterns of pulmonary edema are confusing and often mistaken for the more common causes of focal lung disease, pneumonia, infarction, or aspiration. the authors report four cases of right upper lobe edema secondary to mitral regurgitation. the pathogenesis believed to be responsible for this condition is the vector of blood flow from the left ventricle to left atrium, which may be targeted at the right superior pulmonary vein, locally accentuating the forces for edema formation in the righ ... | 2009 | 2704804 |

the occurrence and growth of microorganisms during the fermentation of fish sausage. | minced fish (mullet) sausage mixes containing added sugar, salt, nitrate, nitrite and spices were fermented (48 h, 30 degrees c) by indigenous flora or by a starter culture (pediococcus acidilactici) and the microbial ecology and behaviour of various bacteria was monitored. pediococcus pentosaceus and lactobacillus plantarum dominated the indigenous fermentation, achieving populations of 10(7)-10(8) cfu/g by 48 h, and decreasing the ph of the mix to 4.5-4.7. significant growth (10(5)-10(7) cfu/g ... | 1991 | 1909546 |
the effect of pediococcus damnosus and pediococcus pentosaceus on the growth of pathogens in minced meat. | the antibacterial effects of one strain of pediococcus damnosus and two strains of pediococcus pentosacaeus against clostridium perfringens, listeria monocytogenes, salmonella infantis and yersinia enterocolitica were investigated. growth inhibition studies were conducted in juice from minced meat incubated at +6 degrees c and +15 degrees c for various periods after the inoculation with pediococci. inhibitory effects were seen for all bacteria tested. | 1991 | 1907475 |
cyclophellitol: a naturally occurring mechanism-based inactivator of beta-glucosidases. | the natural product cyclophellitol, isolated from the culture filtrate of a mushroom, phellinus sp. is found to be a highly specific and effective irreversible inactivator of beta-glucosidases. it inactivates the beta-glucosidases from both almond emulsin and agrobacter sp. according to pseudo-first order kinetics with inactivation constants of ki = 0.34 mm, ki = 2.38 min-1, and ki = 0.055 mm, ki = 1.26 min-1 respectively. no reactivation of the inactivated enzyme is seen upon dialysis, thus pro ... | 1991 | 1904221 |
[3h]mk-801 binding to n-methyl-d-aspartate receptors solubilized from rat brain: effects of glycine site ligands, polyamines, ifenprodil, and desipramine. | the n-methyl-d-aspartate (nmda) receptor is thought to contain several distinct binding sites that can regulate channel opening. in the present experiments, the effects of ligands for these sites have been examined on [3h]mk-801 binding to a soluble receptor preparation, which had been passed down a gel filtration column to reduce the levels of endogenous small-molecular-weight substances. glycine site agonists, partial agonists, and antagonists gave effects similar to those observed in membrane ... | 1991 | 1828832 |
regulation and glucocorticoid-independent induction of lipocortin i in cultured astrocytes. | stimulation of prostaglandin (pg) release in rat astroglial cultures by various substances, including phorbol esters, melittin, or extracellular atp, has been reported recently. it is shown here that glucocorticoids (gcs) reduced both basal and stimulated pgd2 release. hydrocortisone, however, did not inhibit atp-, calcium ionophore a23187-, or tetradecanoyl phorbol acetate (tpa)-stimulated arachidonic acid release, and only tpa stimulations were affected by dexamethasone. gc-mediated inhibition ... | 1991 | 1828830 |
