Purpose Postural orthostatic tachycardia syndrome (POTS) is a form of orthostatic intolerance characterized by an increased heart rate upon transition from supine to standing, and head-up tilt without orthostatic hypotension. Its etiology is multifactorial, and no clear cause has been identified. Common symptoms include light-headedness, blurred vision, weakness, cognitive difficulties, and fat...
Hepatorenal syndrome is a life-threatening complication occurring commonly in cirrhosis liver and rarely in acute liver failure. It can be precipitated by shock, infection, surgery, large volume paracentesis or nephrotoxic drugs. Type I hepatorenal syndrome which usually develops over acute liver failure is rapidly progressive and has poor outcome. Type II hepatorenal syndrome is usually associ...
Hepatorenal syndrome (HRS) is the most serious hepatorenal disorder and one of the most difficult to treat. To date, the best treatment options are those that reverse the mechanisms underlying HRS: portal hypertension, splanchnic vasodilation, and/or renal vasoconstriction. Therefore, liver transplantation is the preferred definitive treatment option. The role of other therapies is predominantl...
Heat shock protein (Hsp90α) has been recently implicated in cancer prompting several attempts to discover and optimize new Hsp90α inhibitors. Toward this end, we explored the pharmacophoric space of 83 Hsp90α inhibitors using six diverse sets of inhibitors to identify high-quality pharmacophores. Subsequently, genetic algorithm and multiple linear regression analysis were employed to select an ...
Simple, precise, selective, and expeditious spectrophotometric methods have been developed for the determination of itopride (ITO), midodrine (MID), diclofenac (DIC), mesalamine (MES), and sumatriptan (SUM) in their pure form as well as in pharmaceutical preparations. The method was based on ion-pair complex formation between the drugs and anionic dye, bromothymol blue in an acidic medium (pH 2...
Hepatorenal syndrome is complication of advanced cirrhosis characterized by renal failure, changes in systemic blood pressure, and increased activity of endogenous vasoactive systems. Renal failure is due to severe renal vasoconstriction developing in the late stages of cirrhosis. The pathogenesis of hepatorenal syndrome is the result of an extreme underfilling of the arterial circulation secon...
BACKGROUND orthostatic hypotension (OH) affects up to 30% of adults over 65 and frequently contributes to falls and syncopal episodes. Current guidelines suggest a wide range of treatments, but systematic reviews of the evidence base for such recommendations are lacking. METHODS we performed a systematic review to assess the evidence for all non-pharmacological and pharmacological interventio...
Neurogenic orthostatic hypotension (nOH) is due to failure of the autonomic nervous system to regulate blood pressure in response to postural changes due to an inadequate release of norepinephrine, leading to orthostatic hypotension and supine hypertension. nOH is common in Parkinson's disease (PD). Prevalence varies throughout the course of PD, ranging from 40% to 60%, and resulting in symptom...
Hepatorenal syndrome is a form of acute or sub-acute renal failure which develops in patients with chronic liver disease. In contrast to other forms of acute renal failure it may be reversible using pharmacological agents. The pathogenesis involves splanchnic vasodilatation and intense renal vasoconstriction. Increasing intravascular volume and prolonged treatment with vasoconstrictor drugs rev...
