There is a whole armament of good drugs for treatment of hypertension including diuretics, calcium antagonist, angiotensin receptor antagonists and angiotensin converting enzyme inhibitors. Secondary drugs mostly used for special indications include beta-blockers, alpha-blockers, mineralocorticoid receptor antagonists (aldosterone antagonists), renin-inhibitors, centrally acting drugs, direct vasodilators and others.A variety of new drugs targeting different pressor mechanism exist and have partly been studies experimentally but will unlikely make it to clinical use in human hypertension...

In dogs, there is no diagnostic test to identify and differentiate fetal fluids from maternal urine in the event that a clear-yellowish vulvar discharge is observed pre-whelping. The objective of this study was to find a test that could easily and accurately identify rupture of the fetal membranes preceding parturition. Maternal urine, and amniotic fluid (AMF) and allantoic fluid (ALF) from only one fetus per bitch, were collected intraoperatively during cesarean section. Specific gravity (SG) was analyzed with a refractometer, whereas the presence of leukocytes, protein, glucose, ketones, bilirubin, urobilinogen, nitrite, erythrocyte/hemoglobin (Hb), and the pH were assessed using a urine dipstick (Combur-Test)...

BACKGROUND: Hypernatremia is a frequent occurrence among hospitalized patients. Severe hypernatremia is associated with mortality rates of over 60 %. Extreme hypernatremia, defined as sodium levels >190 mmol/l, is a rare occurrence. The literature on electrocardiographic changes occurring with this degree of hypernatremia is extremely scarce. We report the case of an 11-year-old Sri Lankan girl who presented with sodium levels of 226 mmol/l following infusion with 3 % hypertonic saline who developed diffuse QT prolongation leading to fatal ventricular tachycardia...

Circadian rhythms synchronize physiological processes with the light-dark cycle and are regulated by a hierarchical system initiated in the suprachiasmatic nucleus (SCN), a hypothalamic region that receives direct photic input. The SCN then entrains additional oscillators in the periphery. Circadian rhythms are maintained by a molecular transcriptional feedback loop, of which BMAL1 is a key member. Disruption of circadian rhythms by deletion of the BMAL1 gene (Bmal1 KO) induces a variety of disease states, including infertility in males, due to unidentified mechanisms...

BACKGROUND: Hypertensive disorders complicate 5-10 % of all pregnancies. Various methods for screening have been studied to identify pregnant women at risk of development of preeclampsia, but no ideal screening test has been identified so far. The objective of this study was to determine the efficacy of urinary calcium-to-creatinine ratio, in a spot urine sample, for the prediction of preeclampsia in asymptomatic pregnant women between 18 and 24 weeks of gestation. METHODS: This study was done on 112 patients presenting to the antenatal clinic in the Department of Obstetrics and Gynecology at Bangalore Baptist Hospital...

Acute aflatoxin exposure can cause death and disease (aflatoxicosis) in humans. Aflatoxicosis fatality rates have been documented to be as high as 40% in Kenya. The inclusion in the diet of calcium silicate 100 (ACCS100), a calcium montmorillonite clay, may reduce aflatoxin bioavailability; thus potentially decreasing the risk of aflatoxicosis. We investigated the efficacy, acceptability, and palatability of ACCS100 in a population in Kenya with recurring aflatoxicosis outbreaks. Healthy adult participants were enrolled in this double-blinded, cross-over clinical trial in 2014...

The hull attached to the barley kernel can be mechanically removed thus reducing the fiber content of the barley. This experiment was carried out to evaluate the effects of partial dehulling on the nutrient digestibility as well as the DE and ME content of barley. Two barley samples (HF and LF) with either high or low fiber contents were obtained from the Hubei and Jiangsu Provinces of China. A portion of the two barleys was mechanically dehulled (DHF and DLF). Thirty barrows (initial BW=31.5±3.2 kg) were assigned to 1 of 5 diets in a randomized complete block design...

Hypertensive disorders during pregnancy are still leading cause for maternal and perinatal death. Calcium metabolism is impaired significantly in women with preeclampsia. Measurement of calcium levels in 24 hours urine sample is easy, modern, fast and not expensive predictive test to reveal women in high risk of developing preeclampsia in late pregnancy. The severity of condition strongly correlates with decrease level of calcium excretion in urine.
