1. The amount of visible or long ultraviolet light (UV) required to photoreactivate Colpidium colpoda injured with known dosages of short UV (2654 A) was determined. 2. The effect of the short UV was tested by the delay in division of exposed animals compared to controls. Photoreactivation was tested by the effect of postillumination on the delay of division of treated colpidia compared to cont...

Methanogenic bioreactor communities were used as model ecosystems to evaluate the relationship between functional stability and community structure. Replicated methanogenic bioreactor communities with two different community structures were established. The effect of a substrate loading shock on population dynamics in each microbial community was examined by using morphological analysis, small-...

As recognized by Irene Manton (1) at the time that the basic 9 + 2 structural uniformity of cilia and most eukaryotic flagella was first becoming recognized, these organelles are sufficiently complex that knowledge of their structure, no matter how detailed, cannot provide an understanding of their mechanisms of growth and function . In our understanding of these mechanisms, the substantial adv...

An extremely halophilic archaeon, strain IC35(T), was isolated from a mud sample of the Aran-Bidgol salt lake in Iran. The novel strain was cream, non-motile, rod-shaped and required at least 2.5 M NaCl, but not MgCl2, for growth. Optimal growth was achieved with 3.4 M NaCl and 0.1 M MgCl2. The optimum pH and temperature for growth were pH 7.0 (grew over a pH range of 6.5-9.0) and 40 °C (grew o...

With the domestic and international proliferation of biobanks and their associated connections to health information databases, scholarly attention has been turning from the ethical issues arising from the construction of biobanks to the ethical issues that emerge in their operation and management. Calls for greater transparency in governance structures, coupled with stern reminders of the valu...

BACKGROUND HIV-related stigma always is major obstacles to an effective HIV response worldwide. The effect of HIV-related stigma on HIV prevention and treatment is particularly serious in China. This study was to examine stigma attitude towards people living with HIV/AIDS (PLWHA) among general individuals in Heilongjiang Province, Northeast China and the factors associated with stigma attitude,...

11523 Background: The safety and efficacy of accelerated hyper-fractionated radiotherapy (RT) combined with temozolomide (TMZ) in patients with high grade astrocytoma have already been reported.Updated results on survival will be presented. METHODS Twenty-four patients with newly diagnosed and histologically proven high grade astrocytoma were enrolled onto this study. Treatment protocol inclu...

AIM To investigate the long-term risk of thromboembolism and serious bleeding associated with oral anticoagulation (OAC) therapy beyond 3 months after radiofrequency ablation (RFA) of atrial fibrillation (AF). METHODS AND RESULTS Linking Danish administrative registries, 4050 patients undergoing first-time RFA (2000-11) were identified. Risk of thromboembolism and serious bleeding according t...

However, coexisting with thes...

BACKGROUND Intestinal schistosomiasis is of public health importance in Uganda but communities living above 1400 m are not targeted for control as natural transmission is thought unlikely. To assess altitudinal boundaries and at-risk populations, conjoint malacological and epidemiological surveys were undertaken on Mount Elgon (1139 m-3937 m), in Fort Portal crater lakes and in the Rwenzori Mou...
