BACKGROUND Apoptotic neuronal death is known as programmed cell death. Inhibition of this progression might contribute to a new treatment strategy. However, methods for in vivo detection of live apoptotic cells are in need to be developed and established. CONTEXT AND PURPOSE The purpose of this study is to develop a new method for in vivo brain imaging for live apoptotic lesions using magneti...

Step-reduction (SR) in older adults results in muscle atrophy and an attenuated rise in postprandial muscle protein synthesis (MPS): anabolic resistance. Knowing that resistance exercise (RT) can enhance MPS, we examined whether RT could enhance MPS following 2 weeks of SR. In addition, as we postulated that SR may impair feeding-induced vasodilation limiting nutrient delivery to muscle, we als...

This pilot study examined whether giving stress reduction (SR) instructions to pregnant women would be effective in regulating stress, mood, and cortisol levels during pregnancy. Forty-one predominantly low-income Latina women, receiving prenatal services at a public county hospital, completed measures of stress and mood (depressive symptoms, positive and negative affect) and provided morning a...

Solitary metastatic brain tumors are the most common intracranial neoplasms encountered by neurosurgeons. Surgical resection of brain metastasis with whole brain radiotherapy (WBR) significantly increases survival in comparison with WBR alone. Stereotactic radiosurgery (SR) seems to provide results that are similar to those of surgical resection. To analyze the economic efficiency of these diff...

Numerous immature thymocytes undergo apoptosis and are rapidly engulfed by phagocytic thymic macrophages. The macrophage surface receptors involved in apoptotic thymocyte recognition are unknown. We have examined the role of the class A macrophage scavenger receptor (SR-A) in the engulfment of apoptotic thymocytes. Uptake of steroid-treated apoptotic thymocytes by thymic and inflammatory-elicit...

The classical scheme of biogeochemical zones (BGZ) is known to be an oversimplification of the microbial processes that occur in organic-rich marine sediments. Results from a coupled deployment of pore-water gel probes in Loch Duich, Scotland, provide direct evidence for rapid recycling within the iron reduction (FeR) and sulphate reduction (SR) zones. High resolution porewater profiles obtaine...

AIMS Tissue Doppler-derived indices of strain (epsilon) and strain rate (SR) have been developed to assess regional cardiac function. However, the effect of left ventricular (LV) size on epsilon and SR has not been studied in depth. The aim of this study was to assess to what extent heart size influence epsilon or SR. METHODS AND RESULTS In 21 anaesthetized pigs ranging from 12.5 to 70.0 kg, ...

The complete amino acid sequence of the fungus Syncephalastrum racemosum (Sr-) nuclease has been delineated on the basis of protein sequencing of the intact protein and its protease-digested peptides. The resulting 250-residue sequence shows a carbohydrate side chain attached at Asn134 and two half-cystine residues (Cys242 and Cys247) cross-linked to form a small disulphide loop. On the basis o...
