A female in her late teens purposely ingested alcohol fuel containing methanol to commit suicide, which she admitted on social media. She was found in distress by her parents and died at the hospital some hours later. Autopsy revealed swelling of the brain and edematous and congestive lungs. No other trauma or unusual findings were revealed at autopsy. Methanol was detected upon routine screening for alcohols by headspace gas chromatography with flame-ionization detection. To confirm the presence of methanol and its metabolite formic acid, a method with detection by mass spectrometry was used...

BACKGROUND: Microvascular function plays an important role in ARVD (atherosclerotic renovascular disease). RFR (renal flow reserve), the capacity of renal vasculature to dilate, is known to reflect renal microvascular function. In this pilot study, we assessed PET (positron emission tomography)-based RFR values of healthy persons and renal artery stenosis patients. Seventeen patients with ARVD and eight healthy subjects were included in the study. Intravenous enalapril 1 mg was used as a vasodilatant, and the maximum response (blood pressure and RFR) to it was measured at 40 min...

Pseudospondias microcarpa is used traditionally for treating various diseases. However, although parts of the plant are extensively used in African traditional medicine, no scientific study has been reported on its toxicity. Therefore, this study evaluated the acute and subacute toxicity studies of the ethanolic extract of P. microcarpa in rats. Male Sprague-Dawley rats (120-150 g) were treated orally with the extract (30, 100, 300, 1000, and 3000 mg kg-1 ) or distilled water (10 ml kg-1 ) for 2 weeks and observed daily for general appearance and signs of toxicity...

Balkan endemic nephropathy (BEN) is an irreversible, lethal kidney disease that occurs in regions of the Balkans where residents drink untreated well water. A key factor contributing to the development of BEN may be consumption of dissolved organic matter leached from low-rank coal called lignite. This hypothesis-known as lignite-water hypothesis-was first posed for areas of the Balkans. It is possible that a BEN-like condition exists in the United States (US) Gulf Coast region in parts of the Mississippi Embayment and the Texas Coastal Uplands aquifers -Arkansas, Louisiana, and Texas, for instance-that rely heavily on groundwater from aquifers that contain lignite...

Trachinotus ovatus is a stenohaline fish and widely cultured in the ponds and gulf on the southeast coast of China. The dramatic salinity decrease caused by heavy rainfall could cause mass mortality of T. ovatus in aquaculture. It is very important to understand the osmoregulatory mechanism of T. ovatus. Na+ /K+ /2Cl- cotransporter 1a (NKCC1a) is involved in the osmoregulation of fish and plays a crucial role in cell volume homeostasis and maintenance of the electrolyte content. In this study, we characterized nkcc1a (designed as Tonkcc1a) from T...

One of the most common causes of mortality in acute kidney injury is brain dysfunction. Here we investigated the possible protective effect of erythropoietin (EPO) on cognitive impairments induced by bilateral renal ischemia (BRI). Eighty male Wistar rats were allocated into 8 groups: 1, 2) Sham +V (Vehicle), 3, 4) Sham+EPO, 5, 6) BRI+V, 7, 8) BRI+EPO. The groups followed by the reperfusion periods of 24hours (24 h) and 1week (1w). EPO or saline was administrated 30 min before surgery (1000 IU/kg, i.p). The cognitive function was assessed by passive avoidance learning and Morris water maze tests...
