At least three well documented neuropharmacologic mediators participate in physiologic erection: inhibition or cessation of alpha-adrenergic transmission, increases in both cholinergic (acetylcholine) and non-adrenergic non-cholinergic (NANC) transmission. In-vitro studies of rabbit corporal smooth muscle reveal that adenosine tri-phosphate (ATP) has a(More)
The removal of Cu(II) by a mesoporous material, FSM-16, was studied using electron paramagnetic resonance (EPR) spectroscopy and surface complexation modeling (SCM). Free copper ions, adsorbed and precipitated Cu(II) species were qualitatively identified by in situ EPR spectroscopy of Cu-FSM-16 suspensions at room temperature and at 77 K. In addition, the(More)
OBJECT A wide variation in postoperative drainage volumes is observed during treatment of chronic subdural hematoma (CSDH) with twist-drill or burr-hole craniostomy and closed-system drainage. In this study the authors investigate the causes of the variation, the clinical significance thereof, and its influence on treatment outcome. METHODS A total of 175(More)
We investigated the effect of vasoactive intestinal peptide (VIP) and its combination with acetylcholine (ACh) on the erectile response in 52 adults rats. Intracavernous injection of VIP (10(-8) to 10(-5)M, ACh (10(-9) to 10(-5), or a combination of VIP (10(-7) to 10(-5) with ACh (10(-6 M) additively enhanced that erection but did not lead to a full(More)
The two cases presented here involve deaths that were due to dichloromethane or chloroform poisoning. The dichloromethane and chloroform were determined in biological specimens by headspace gas chromatography with mass spectrometric detector. In one case, dichloromethane concentrations found were 252 mg/L (blood), 75 mg/kg (brain) and 30 mg/kg (heart). From(More)
This study describes the use of gas chromatography/mass spectrometry with selected ion monitoring to screen 18 anabolic steroids banned by the International Olympic Committee. These anabolic steroids are analyzed in two fractions depending on their excretion pattern: nonconjugated (free) or conjugated fraction. The wet procedure of extracting steroids from(More)
The efficacy and safety of sildenafil was evaluated in a randomiSed, double-blind, placebo-controlled, flexible-dose study in Korean men aged 28-78 y with erectile dysfunction (ED) of broad-spectrum aetiology and more than 6 months duration. A total of 133 patients were randomised at six centres in Korea to receive either sildenafil (50 mg initially,(More)
Reciprocal interactions between cancer cells and the tumor microenvironment drive multiple clinically significant behaviors including dormancy, invasion, and metastasis as well as therapy resistance. These microenvironment-dependent phenotypes share typical characteristics with cancer stem cells (CSC). However, it is poorly understood how metabolic stress(More)
Histone deacetylases 8 (HDAC8) is an enzyme repressing the transcription of various genes including tumour suppressor gene and has already become a target of human cancer treatment. In an effort to facilitate the discovery of HDAC8 inhibitors, two quantitative structure-activity relationship (QSAR) classification models were developed using K nearest(More)
We have designed a venous compression device implantable at the base of the penis outside the tunica albuginea. Because it does not require exposure of individual veins for ligation, the risk to the cavernous nerve is practically nil. It occludes the venous return only temporarily, and thus collaterals are less likely to occur. In this preliminary acute(More)
