OBJECTIVE Platelet-activating factor acetylhydrolase (PAF-AH) expresses a Ca2+-independent phospholipase A2 activity and hydrolyzes platelet-activating factor as well as oxidized phospholipids. Two major types of PAF-AH have been described: the plasma type, which is associated with lipoproteins, and the intracellular type II PAF-AH. METHODS AND RESULTS We investigated the type(s) of PAF-AH ex...

This paper summarises the general pattern of urban land-cover change in the Northeastern Illinois between 1972 and 1997 using Landsat acquired remotely sensed images. The region, centred by the city of Chicago, experienced dramatic land cover change in the past decades. Accompanying the redistribution of population and decentralisation of metropolitan functions are the tremendous growth and dev...

healthy hire effect (hhe) is considered as an epidemiological phenomenon, complicating the assessment of a true cause - effect relationship between occupational exposure and health status of workers. the current study was aimed at identification and elimination of hhe in the risk assessment of arterial hypertension (ah) in coal miners. overall, 1553 miners, working in west siberia, were enrolle...

l,rAzobis[3-methyl-2-phenyl-lH-imidazo(l,2-a)pyridinium] dibromide, AH 8165, produced a competitive neuromuscular block in the mouse, chick, cat, dog and monkey. The paralysis was characterized by a very rapid onset of action and, in all species except the monkey, by a short duration of action comparable to that of suxamethonium. In the monkey, the effect of AH 8165 was more persistent but was ...

One-hundred ninety-two crossbred steers (initial BW = 351 +/- 11 kg) were used to determine the effects of removing alfalfa hay (AH) from dry-rolled corn-based diets containing wet corn gluten feed (WCGF) on animal performance and nutrient (N and OM) mass balance in open feedlot pens. Steers were stratified by weight and assigned randomly to 24 pens (2 x 3 factorial) and fed for 132 d from June...

OBJECTIVE The aim of this study was to compare the cytotoxic effects of endodontic cements on human tooth germ stem cells (hTGSCs). MTA Fillapex, a mineral trioxide aggregate (MTA)-based, salicylate resin containing root canal sealer, was compared with iRoot SP, a bioceramic sealer, and AH Plus Jet, an epoxy resin-based root canal sealer. MATERIAL AND METHODS To evaluate cytotoxicity, all mat...

BACKGROUND Arterial hypertension (AH) is a main risk factor for the risk from cardiovascular (CVD) and stroke mortality. Only few data was published on prevalence, awareness and management of AH in Lithuania. Development of objective approaches to the treatment and control of AH reduces the risk of mortality. The aim of this study was to evaluate time trends, the prevalence, awareness, treatmen...

INTRODUCTION Assessment of cellular cytotoxicity is a regular method for evaluating the biocompatibility of novel materials. In a recent study, 5% fluoride varnish (Duraflur) has shown reasonable sealing ability and coverage of root canal walls when used as a sealer. The aim of the present study was to compare the cytotoxicity of Duraflur varnish with two popular commonly used root canal sealer...

Our aim was to find out if immunoglobulins for intravenous use (IVIG) contain IgG-anti-F(ab')2γ (AFab2) and IgG-antiHinge (AH) antibodies (Ab.) and to discuss how AFab2, in particular AH could contribute to immunomodulatory effect of IVIGs. We measured IgG, AFab2 and AH in five IVIG products approved for therapeutic use. IVIG showed higher AFab2 and AH concentration than sera of randomized heal...

OBJECTIVE In search of an ideal method of assisted hatching (AH), we compared the effects of conventional micropipette-AH and laser-AH on the blastocyst formation rate (BFR) and blastocyst cell numbers. METHODS Four- to five-week-old ICR female mice were paired with male mice after superovulation using Pregnant mare's serum gonadotropin (PMSG) and hCG. The two-cell embryos were flushed from t...
