The beta-decay of Kr is a significant radioactive background for experiments that use liquified noble gases to search for dark matter and measure the low-energy solar neutrino flux. While there are several proposed methods for reducing Kr levels in these experiments, an independent technique is needed for measuring very low Kr levels. By selectively exciting Kr atoms to a metastable state, capt...

The purpose of the present experiment was to examine further earlier suggestions that a reduced relative frequency of knowledge of results (KR) can enhance the learning of generalized motor programs (GMPs) but at the same time degrade parameter learning, compared with giving KR after every trial (Wulf & Schmidt, 1989; Wulf, Schmidt, & Deubel, 1993). In contrast to these earlier studies, here KR...

The 4.6-hour Kr" period was reported by SnelP as a result of deuteron bombardment of krypton. The Kr" period was not obtained by Clancy' as a result of alpha-particle bombardment of selenium. In the latter bombardments, only a 114-minute krypton period, assigned to the excited level of stable Kr~, and a 33-hour krypton period, assigned to Kr ' ", were observed. The Kr'~ period was then consider...

The opening of the adenosine triphosphate (ATP)-sensitive potassium (KATP) channel has been proposed as a therapeutic approach for ischemia. Here we examined the opening effect of KR-31378 on the KATP channel using patch clamp recording in neuroblastoma 2a (N2a) cells and investigated the neuroprotective effect of KR-31378 in organotypic hippocampal slice cultures exposed to oxygen/glucose depr...

A new species of indotyphlid caecilian amphibian, Gegeneophis tejaswini sp. nov., is described based on eight specimens from lowlands of the most northerly district of the state of Kerala in the southern part of the Western Ghats region, India. This species is distinguished from all other Gegeneophis in annulation characters and genetics (> 6% different from most similar nominal species for ...

The antibiotic kirromycin (Kr) inhibits bacterial protein synthesis by binding to elongation factor Tu (EF-Tu). Streptomyces cinnamoneus and Nocardia lactamdurans, producers of antibiotics of the Kr class, are known to possess an EF-Tu resistant to Kr. Both micro-organisms appear to possess a single tuf gene and we have characterized the one from S. cinnamoneus, which belongs to the tuf1 family...

Complications of atherosclerosis are the leading cause of death of patients with type 2 (insulin-resistant) diabetes. Understanding the mechanisms by which insulin resistance and hyperglycemia contribute to atherogenesis in key target tissues (liver, vessel wall, hematopoietic cells) can assist in the design of therapeutic approaches. We have shown that hyperglycemia induces FoxO1 deacetylation...
