Biochemical Aspects Of Ketosis DocosahexaenoicAcid

Fri, 17 Feb 2012 00:16:16 GMT

The KD was originally formulated to mimic the effects of fasting, as it had been known since biblical times that fasting had a beneficial effect on epilepsy Geyelin, 1921 Wheless, 1995 Swink et al., 1997 . Ever since, it has been assumed that fasting and the KD share a common mechanism of action, although this assumption has not been proven. Dietary fats and fatty acids are ordinarily broken down by liver mitochondrial P-oxidation into two-carbon acetyl-CoA molecules. Acetyl-CoA is ordinarily...

While most genes are silenced on the Xi and expressed from the Xa, the XIST gene XIST in humans and Xist in mouse shows the opposite expression pattern. XIST encodes a 17-Kb, spliced, polyadenylated, non-coding RNA that stably associates with the entire Xi, appearing to coat this chromosome Brockdorff et al. 1992 Brown et al. 1992 . XIST RNA's ability to coat the Xi depends on the tumor suppressor gene product BRCA1 in BRCA1 mutant cells, XIST RNA does not coat the Xi, although it is produced...

Although no specific blood pressure is pathognomic, the elevated pressure must exceed the limits of cerebral autoregulation of the small-resistance arteries, resulting in cerebral hyperperfusion with loss of integrity of the blood-brain barrier. In most cases, autoregulation usually cannot accommodate a constant cerebral blood flow above a MAP of 150 to 200 mmHg. Immediate reduction of blood pressure by 20 to 25 percent will help reverse the vasospasm that occurs at these pressures however,...

Dietary fat has little, if any, immediate effect on blood glucose concentration because the constituent fatty acids do not produce new glucose and the glycerol moieties are insignificant in their contribution to blood glucose. However, there is considerable evidence that circulating free fatty acids promote gluconeogenesis and hyperglycemia. In a normal overnight fast this is good Fatty acids help maintain normoglycemia. However, in uncontrolled diabetes, when fatty acids can be very high, they...

Class I Antidysrhythmic Agents EmergencyMedicine

Wed, 15 Feb 2012 19:04:41 GMT

PROCAINAMIDE Procainamide is useful as an antidysrhythmic agent in the treatment of various ventricular and supraventricular dysrrhythmias. Procainamide was developed after the antidysrhythmic effects of the local anesthetic agent procaine were realized. However, procaine's short duration of action and its prominent central nervous system CNS effects rule it out for its clinical use. Like all class I agents, procainamide blocks sodium channels and depresses the speed of impulse conduction phase...

A married woman or man who takes a lover may only be indulging in a dalliance, in which case he or she may view it as irrelevant to the marriage. But when an adulterous affair becomes a passion rather than a diversion, a split-object triangle develops with a split in valuation between the spouse and the lover, the marriage and the affair. The spouse, if not actually loathed, comes to be seen as at the very least limited. The marriage, if not bad, is experienced as stultifying. The lover comes...

Accommodation is defined as a change in the threshold of an excitable membrane when slow depolarization is applied. In the previous examples, rapid depolarization is applied, and the threshold occurs at a relatively fixed membrane potential e.g., Fig. 3 . When a slowly developing depolarization is applied, however, the threshold is frequently at a more depolarized level and, indeed, if the depolarization is slow enough, no action potential will be initiated despite the level of depolarization....

The underfill hypothesis has been challenged on several fronts. Lieberman, Levy, their co-workers, and others have advanced clinical and experimental data which challenge the early sequence shown in Fig. 1 15,16 . Careful studies of dogs with experimental cirrhosis and patients with early hepatic cirrhosis demonstrate that renal salt and water retention can develop prior to the formation of ascites or edema. The classic underfill hypothesis requires that ascites and or edema develop first, to...
