The aryl hydrocarbon (Ah) receptor has occupied the attention of toxicologists for over two decades. Interest arose from the early observation that this soluble protein played key roles in the adaptive metabolic response to polycyclic aromatic hydrocarbons and in the toxic mechanism of halogenated dioxins and dibenzofurans. More recent investigations have provided a fairly clear picture of the ...

BACKGROUND The rate of alcohol relapse among patients who underwent liver transplantation for alcoholic hepatitis (AH) is not precisely known. AIM Synthesize the available evidence on liver transplantation for AH to assess alcohol relapse and 6-month survival. METHODS Meta-analysis of trials evaluating liver transplantation for AH, either clinically severe or diagnosed on the explant. RES...

A constant intravenous infusion of phenylephrine (0.74±0.41 ,ug/kg/min) was given to 10 patients to cause a continuous augmentation in reflex vagal tone. After the infusion, the diastolic blood pressure increased from 76±7 to 89±11 mm Hg (p<0.01). The sinus cycle length and atrial-His (AH) interval were measured, and incremental atrial pacing was performed before and during phenylephrine infusi...

AIM The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation. MATERIALS AND METHODS Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were ob...

Aim: Most endodontic sealers show antimicrobial activity before setting, but most of them also lose this ability after setting. Addition of an antibiotic may affect the properties of sealers such as sealing ability, setting time, and so on. The aim of this study was to assess whether the addition of antibiotics (amoxicillin, doxycycline, and clindamycin) improves the sealing ability of AH 26 se...

BACKGROUND There are no absolute criteria for identifying those girls with idiopathic central precocious puberty (CPP) who will benefit from gonadotropin-releasing hormone analog (GnRHa) treatment. Our objective was to predict at initial evaluation the differences between adult height (AH) and target height (TH) and (for untreated girls) the time between puberty onset and first menstruation. ...

Acquired hypoparathyroidism (AH) has been considered to result from an autoimmune process but the self-antigens have not been identified. We studied 25 patients with AH, of which 17 had type I autoimmune polyglandular syndrome and 8 had AH associated with autoimmune hypothyroidism. Five of 25 (20%) AH sera reacted to a membrane-associated antigen of 120-140 kD in human parathyroid gland extract...

BACKGROUND/AIM Adenoid hypertrophy (AH) is one of the most frequent pediatric disorders. The aim of this study was to investigate the effects of TLR2-R753Q, TLR4-T399I, and TLR4-D299G polymorphisms in children with AH. MATERIALS AND METHODS The variants of the TLR gene were determined by restriction fragment length polymorphism (PCR-RFLP) analysis in 60 patients with AH and in 50 healthy chil...

The optimal roughage concentration required in feedlot diets changes continuously for many reasons such as source, availability, price, and interaction with other ingredients in the diet. Wet distillers grains and solubles (WDGS) are common in finishing diets and they contain relatively high amounts of fiber compared with other grains they replace. Therefore, concentration of roughage could be ...

lmidazolate bridged homo/hetero binuclear complexes of copper(II), nickei(II) and zinc(II) formed with glycylvalinate have been studied by pH-metry, EPR and visible absorption spectrometry in aqueous medium at 25 ± I 0 and I= 0.1 M NaCI04• The experimental data have been obtained for the followin~ species (A. = glycylvalinate and 8 =imidazole) :M +, AHt , AH, A·, 8W, 8 , M(OHt.
