Chapmannia Torrey & Gray, a monotypic legume genus of Florida, is shown to have perfect flowers, rather than sterile and fertile flowers incorrectly attributed to the genus by authors for the past one hundred years. The species is described and illustrated with accompanying notes on its habitat, distribution, reproductive biology, phylogeny and cytology. 相似文献

A technique that allows for easy identification of transformants ofNeisseria gonorrhoeae in the absence of selective pressure has been developed. A suicide vector that contains a gonococcal DNA uptake sequence was constructed to aid in DNA uptake. In this transformation procedure, a limiting number of cells is incubated with an excess amount of DNA, and the mixture is plated onto a non-selective medium. At least 20% of the resulting colonies contained cells that had been transformed. This strategy was utilized to construct specific deletions of the S.NgoI, II, IV, V and VII restriction-modification (R/M) genes. All five deletions were successfully incorporated into the chromosome of FA19, producing strain JUG029. Strain JUG029 could be transformed with non-methylated plasmid DNA while strain FA19 could not be transformed with such DNA. The development of a simple, non-selective transformation technique, coupled with the construction of a strain that is more permissive for DNA-mediated transformation, will aid in genetic manipulations of the gonococcus. 相似文献

OBJECTIVE--To describe the prevalence of psychiatric disorder and the treatment needs of sentenced prisoners in England and Wales. DESIGN--Population survey based on a 5% sample of men serving prison sentences. SETTING--Sixteen prisons for adult males and nine institutions for male young offenders representative of all prisons in prison type, security levels, and length of sentences. SUBJECTS--406 young offenders and 1478 adult men, 404 and 1365 of whom agreed to be interviewed. MAIN OUTCOME MEASURES--History of psychiatric disorder, clinical diagnosis of psychiatrist, and required treatment. RESULTS--652 (37%) men had psychiatric disorders diagnosed, of whom 15 (0.8%) had organic disorders, 34 (2%) psychosis, 105 (6%) neurosis, 177 (10%) personality disorder, and 407 (23%) substance misuse. 52 (3%) were judged to require transfer to hospital for psychiatric treatment, 96 (5%) required treatment in a therapeutic community setting, and a further 176 (10%) required further psychiatric assessment or treatment within prison. CONCLUSIONS--By extrapolation the sentenced prison population includes over 700 men with psychosis, and around 1100 who would warrant transfer to hospital for psychiatric treatment. Provision of secure treatment facilities, particularly long term medium secure units, needs to be improved. Services for people with personality, sexual, and substance misuse disorders should be developed in both prisons and the health service. 相似文献

Tibetan medicine historically has had multiple medical lineages, despite ancient, shared literary medical canons. However,
since the second half of the 20th century in Tibet, increasing state control and commoditization has lead to centralization
and standardization of Tibetan medicine. Here we investigate how much variation in the use of medicinal plants remains in
contemporary Tibetan medicine. Medicinal plants used and/or sold by fifteen Tibetan medical institutions, markets, and doctors,
as well as two additional non-Tibetan markets, are inventoried and vouchered (where allowed). The data are ordered by Non-metric
Multidimensional Scaling. Four distinct groups are defined: (1) government recognized Tibetan medical institutions and their
disciples both in Lhasa and elsewhere, (2) local herbal doctors near Mt. Khawa Karpo, eastern Himalayas, (3) Tibetan medicinal
markets in Lhasa and near Mt. Khawa Karpo, and (4) non-Tibetan medicinal markets near Dali and Kunming, Yunnan. This clearly
documents the plurality of Tibetan medical traditions—official, local, and market—while differentiating these from non-Tibetan
markets. 相似文献
