Aging is associated with a loss in muscle known as sarcopenia that is partially attributed to apoptosis. In aging rodents, caloric restriction (CR) increases health and longevity by improving mitochondrial function and the polyphenol resveratrol (RSV) has been reported to have similar benefits.

Mechanisms of Ageing and Development

Understanding the trade-offs between organisms' life history traits has been a major goal of physiology, ecology and evolution. In the last few decades, two types of intra-specific studies have highlighted the trade-off between growth and longevity. First, diet restriction (DR), as an environmental intervention, has been shown to suppress growth and extend the lifespan of a broad range of animals. Second, genetic studies have also shown that mice, whose growth hormone function is genetically modified (GM), grow slower and live longer than their wild-type siblings.

OBJECTIVES: Previous studies have shown that grounding produces quantifiable physiologic changes. This study was set up to reproduce and expand earlier electrophysiologic and physiologic parameters measured immediately after grounding with improved methodology and state-of-the-art equipment. DESIGN AND SUBJECTS: A multiparameter double-blind experiment was conducted with 14 men and 14 women (age range: 18-80) in relatively good health. Subjects were screened for health problems using a commonly used health questionnaire.

Several 1-aryl-3-(2-pyrimidyl)thiocarbamides and their corresponding cyclized 2-arylimino-3-(2-pyrimidyl)thiazolid-4-ones were synthesized and characterized by their sharp melting points and elemental analyses. These thiocarbamides and thiazolidones possessed anticonvulsant activity against pentylenetetrazol-induced convulsions and potentiated pentobarbital-induced hypnosis in mice. Most of these thiocarbamides and thiazolidones selectively inhibited nicotinamide adenine dinucleotide (NAD)-dependent oxidation of pyruvate, where the use of added NAD dether hand, remained unaltered.

1. To investigate the stimulus to the cardiovascular and respiratory systems during isometric exercise, two patients with sensory neuropathies affecting forearm afferent nerves were studied and their circulatory and respiratory responses compared with those of normal subjects. The contribution of pain to the cardiorespiratory changes was also investigated in normal subjects by using hypnosis to relieve pain during and after isometric exercise. 2.

We have studied the effects of chlormethiazole infusion on the ventilatory response to progressive isocapnic hypoxia in seven healthy volunteers, during both normocapnia and induced hypercapnia. The dose of chlormethiazole was such that it produced the same degree of hypnosis as would be expected from oral administration of two capsules each containing 192 mg of base in arachis oil. Ventilation did not change significantly during chlormethiazole administration. The ventilatory response to hypoxia was unaffected by chlormethiazole during normocapnia and was enhanced during hypercapnia.

Sufentanil, a synthetic opioid that is 5-10 times as potent as fentanyl, has been suggested for use during neurosurgical procedures because it maintains cardiovascular stability and produces hypnosis without the use of additional anesthetic agents. Doses as low as 2.5 micrograms.kg-1 are reported to create deep levels of anesthesia as demonstrated by EEG changes to high-amplitude delta-waves. However, there are no reports concerning the effects of sufentanil on blood flow and metabolism in the human brain.
