Acupuncture is a popular complementary treatment option in human medicine. Increasingly, owners also seek acupuncture for their animals. The aim of the systematic review reported here was to summarize and assess the clinical evidence for or against the effectiveness of acupuncture in veterinary medicine. Systematic searches were conducted on Medline, Embase, Amed, Cinahl, Japana Centra Revuo Medicina and Chikusan Bunken Kensaku. Hand-searches included conference proceedings, bibliographies, and contact with experts and veterinary acupuncture associations.
BACKGROUND: Indian medicinal plants used in the Ayurvedic traditional system to treat diabetes are a valuable source of novel anti-diabetic agents. Pancreatic ?-amylase inhibitors offer an effective strategy to lower the levels of post-prandial hyperglycemia via control of starch breakdown. In this study, seventeen Indian medicinal plants with known hypoglycemic properties were subjected to sequential solvent extraction and tested for ?-amylase inhibition, in order to assess and evaluate their inhibitory potential on PPA (porcine pancreatic ?-amylase).
Three new polyhydroxytriterpenoid derivatives, 23-O-neochebuloylarjungenin 28-O-?-d-glycopyranosyl ester (1), 23-O-4'-epi-neochebuloylarjungenin (2), and 23-O-galloylpinfaenoic acid 28-O-?-d-glucopyranosyl ester (17) were isolated from the fruits of Terminalia chebula Retz. along with fourteen known ones. Their structures were elucidated by 1D and 2D NMR spectroscopic data and acid hydrolysis.
Four classes of etiologic agents that cause human illness have been discovered. Sometimes members of two or more classes of agents cooperate to cause illness. Knowledge of etiology is necessary if a disease is to be eradicated. The leading causes of death in the United States have changed dramatically in the last century. Infection has been replaced by chronic illnesses of obscure etiology. Ischemic heart disease is the leading cause of death in middle age and is the major obstacle to becoming old.

A fundamental question in the basic biology of aging is whether there is a universal aging process. If indeed such a process exists, one would expect that it develops at a higher rate in short- versus long-lived species. We have quantitated pentosidine, a marker of glycoxidative stress in skin collagen from eight mammalian species as a function of age. A curvilinear increase was modeled for all species, and the rate of increase correlated inversely with maximum life-span.
The underlying mechanism of calorie restriction (CR) extension of mammalian life spans operates by altering the rate of decline in reserve capacity (with time) as well as the exposure to growth stimulus, two mechanisms that seem to be related to the central genetically determined mechanism that controls mammalian life span over a 50-fold range.
Iron is estimated to be deficient in the diets of one fifth of the world's population. Iron is commonly provided as a supplemental nutrient in industrialized countries for uses of choice. In other countries of the world, it may be required as an overt addition to the diet to prevent iron deficiency. This may be accomplished through fortification of a common food. As a micronutrient, iron has a relatively narrow range of safety--whether given as a supplement or fortificant, it must be in a high enough dose to be appreciably absorbed, but low enough to avoid toxicity.
Since 1960, clinical organ transplantation has evolved from an experimental procedure to highly successful 'routine', but as technical advances have extended eligibility to more victims of end-stage organ disease, the supply of donor organs has lagged behind. Urgency of need, probability of success and ability to pay are often used to limit waiting lists; without these, as many as 124,000 transplants per year could be performed in the USA alone.
OBJECTIVE: This study sought to evaluate whether surgical clips affect tissue conductivity and thereby alter the induction of radiofrequency ablation lesions and to determine whether therapy is safe after previous placement of clips in the liver. MATERIALS AND METHODS: An ex vivo porcine hepatic model was used. Three clips were placed around a radiofrequency electrode at 10, 20, and 30 mm from the point of insertion. Clips were arranged in a plane either perpendicular or parallel to the electrode track.
Midazolam is a water-soluble benzodiazepine proven to be efficacious in sedation, hypnosis, and induction and maintenance of anesthesia. Because of its water solubility, it is a desirable drug for the control of status epilepticus when intravenous (IV) access is not obtainable. This study compares intramuscular (IM) versus IV routes of administration of midazolam in the control of tonic-clonic activity produced by chemically induced generalized seizures in a swine model.
