Eight year study of viral isolates from cot deaths in Glasgow

Over an eight year period 21 different viral strains excluding polioviruses were isolated in 44 (19%) of 237 cot deaths. The percentage of viral positive cases was significantly greater in over 16 week age groups and in cultures obtained less than 24 hours after death.     

Isolated sphenoiditis: a diagnostic problem

A case of primary isolated sphenoiditis that developed cavernous sinus thrombosis is presented. It is difficult to diagnose and patients are often not seen initially by an ENT surgeon, making it more important for other branches of medicine to be aware of this condition. We discuss isolated sphenoiditis with particular reference to the diagnosis, management and complications of this condition.     

3,5-甾二烯化合物的合成及抗早孕活性

以18-甲基-17β-羟基-17α-乙炔基-雌甾-4-烯-3-酮(18-甲基炔诺酮),17β-羟基-17α-乙缺基-雌甾-4-烯-3-酮(炔诺酮),17β-羟基-17α-乙炔基-雄甾-4-烯-3-酮(妊娠素)和17a-羟基孕甾-4-烯-3,20二酮(17α-羟基黄体酮)为原料,经NaBH,还原、脱水、双键转位和酯化等反应合成一系列3,5-甾二烯化合物,用¹HNMR和MS证明了它们的结构。动物筛选结果表明,17β-丙酰氧基-17α-乙炔基-雌甾-3,5-二烯(IV_b2有明显的抗早孕活性。中断早期妊娠的作用似与其雌激素活性有关。     

New reference allelic ladders to improve allelic designation in a multiplex STR system

This paper reports the composition of a new reference allelic ladder mixture for use with a multiplex DNA profiling system consisting of six short tandem repeat loci. The loci included in this mixture are HUMTH01, D21S11, D18S51, D8S1179, HUMVWAF31/A, HUMFIBRA/FGA and an amelogenin sex test. Sequence analysis of individual ladder alleles was carried out and allelic designations made in accordance with the recommendations of the International Society of Forensic Haemogenetics (1992; 1994). A series of rare alleles which increase the range of alleles previously reported were identified. By including some of the rare alleles into the ladder marker system, we have significantly improved the ability to identify new alleles in unknown samples.

Topical antimicrobials: new horizons for management of periodontal disease in general practice?

One of the most prevalent infectious diseases that dental practitioners have to treat is periodontal disease. Antimicrobial and antibiotic agents have been developed that can be applied topically with no deleterious side-effects and reaching greater concentrations at the disease site than such agents given systemically. Used in conjunction with the mechanical debridement of deep pockets of disease, these agents appear to enhance the effectiveness of treatment. This approach is likely to feature more and more in the routine management of periodontal disease.     

Isolation and characterization of Mycoplasma sphenisci sp. nov. from the choana of an aquarium-reared jackass penguin (Spheniscus demersus)

Strain UCMJ was isolated from the choana of a jackass penguin (Spheniscus demersus) with recurrent mucocaseous choanal discharge. Isolation of this mycoplasma expands the known range of species hosting mycoplasmas. The name Mycoplasma sphenisci sp. nov. is proposed for this new species, for which strain UCMJ is the type strain.
