PURPOSE: Previous studies in various medical specialties have shown that fewer than 50% of abstracts presented at meetings are subsequently published. The purpose of the present study was to determine the publication rate of abstracts presented at the annual meetings of the American Association of Oral and Maxillofacial Surgeons. MATERIALS ...

San Francisco held this year's annual meeting of the American Academy of Allergy, Asthma and Immunology at the Moscone Center, where oral and poster sessions, educational courses and informal discussions called to the mind of attendees important news on a wide range of topics, including the main subject of this ...

This Applied Optics feature issue on Laser Applications to Chemical, Security, and Environmental Analysis (LACSEA) highlights topics and papers presented at the LACSEA 2010 Twelfth Topical Meeting sponsored by the Optical Society of America.

The Netherlands is again facing a sharp increase in Q fever notifications, after the unprecedented outbreaks of 2007 and 2008. The most affected province of Noord Brabant has a high density of large dairy goat farms, and farms with abortion waves have been incriminated. Mandatory vaccination of small ruminants has ...

Six cularine alkaloids, cularicine, O-methylcularicine, celtisine, cularidine, cularine and celtine, three isocularine alkaloids, sarcophylline, sarcocapnine and sarcocapnidine, and five non-cularine alkaloids, glaucine, protopine, ribasine, dihydrosanguinarine and chelidonine, were identified and quantified by GC-MS in nine taxa of the genus Sarcocapnos (Fumariaceae). The chemotaxonomic significance of the results is discussed.

The isoquinoline alkaloids protopine, cryptopine, sinactine, stylopine, bicuculline, adlumine, parfumine, fumariline, fumarophycine, fumaritine, dihydrofumariline, parfumidine and dihydrosanguinarine have been determined and identified by gas chromatography-mass spectrometry in Fumaria agraria, F. bastardii, F. capreolata, F. sepium, F. densiflora, F. faurei, F. officinalis subsp. officinalis, F. parviflora, F. petteri subsp. calcarata and ...

Three novel quaternary indole alkaloids with an unprecedented 1-azoniatricyclo[4.3.3.0(1,5)]undecane moiety, subincanadines A-C (1-3), as well as two new indole alkaloids with a 1-azabicyclo[5.2.2]undecane moiety, subincanadines D (4) and E (5), and a new indole alkaloid with a 1-azabicyclo[4.3.1]decane moiety, subincanadine F (6), have been isolated from the barks of Aspidosperma ...

During 1981, 52 cases of rickettsiosis caused by the spotted fever group of rickettsiae were reported in a population of 250 000 living in the Negev desert region of Israel. Retrospectively, at least 5 of these cases were serologically shown to have been caused by Rickettsia typhi, the agent of ...

Clinical improvement was rapid in all 13 patients with enteric fever and one with Brucella abortus infection treated with trimethoprim-sulphamethoxazole. There were no side-effects of the treatment and it was found easy to administer to toxic and delirious patients.

Fourteen cases are described in which the local application of corticosteroid preparations to ringworm infections of the skin have resulted in unusual clinical pictures. A kerion-like lesion due to Trichophyton rubrum, intertriginous infections simulating candidiasis and due to Epidermophyton floccosum, and pictures resembling poikiloderma, papular rosacea, and indeterminate leprosy are ...

A Canada-wide survey of Q fever was begun in 1958 in co-operation with public health and veterinary laboratories to determine the presence and prevalence of the disease so that medical practitioners might be alerted to the potential dangers existing. Serologic evidence obtained indicated that the Q fever rickettsia now exists ...

Clinical and pathological features of two fatal cases of bacterial endocarditis with Candida albicans superinfection are described. One patient presented with combined Streptococcus viridans and Candida endocarditis of the aortic valve. The second patient, an addict to paregoric injected intravenously, developed Staphylococcus aureus of the tricuspid valve with eventual Candida ...

A study has been made of developmental variations in anthers of Lilium longiflorum with respect to the deamination of deoxycytidine and 5-methyldeoxycytidine. Although a periodicity of enzymatic activities surrounding the mitotic cycle has been found, the over-all evidence is against the significance of such periodicity to chromosome duplication. On the ...
