objective: several recent studies have shown that mitochondrial dna mutations lead to major disabilities and premature death in carriers. more than 150 mutations in human mitochondrial dna (mtdna) genes have been associated with a wide spectrum of disorders. varicocele, one of the causes of infertility in men wherein abnormal inflexion and distension of veins of the pampiniform plexus is observ...

background: maxillary sinuses are covered by a 1 mm thick mucous membrane that when this membrane becomes infl amed, the thickness may increase 10-15 times. the common causes of odontogenic sinusitis are dental abscesses and periodontal disease. computed tomography (ct) is considered the gold standard for sinus diagnosis. recently, cone beam computed tomography (cbct) has been introduced for de...

BACKGROUND Because metallothionein (MT) is a metal-binding protein that protects against metal intoxication, it could be a biomarker for individual sensitivity to metal toxicity. OBJECTIVE We assessed the use of bloodborne MT transcript as a reflection of tissue MT levels and examined the potential role of MT in arsenic toxicity in an environmentally exposed human population. METHOD Rodents...

Two isostructural 1D compounds {[M3(hpdc)2(H2O)6] 2H2O}n (M = Mn, Co; H3hpde = 2-hydroxypyrimidine-4,6-dicarboxylic acid) were synthesized by the in situ hydrothermal reactions of 2-chloropyrimidine-4,6-dicarboxylic acid with MCl2 (M = Mn, Co) and NaOH; the MnII compound shows spin-canted antiferromagnetism, whereas the CoII compound exhibits the coexistence of spin-canting and a two-step field...

objective: recent studies have shown that the use of prolonged and intermittent normobaric hyperoxia (95%) decrease the infarct volume of stroke. the aim of current study was to study the effect of an oxygen radicals-scavenger applied during intermittent normobaric hyperoxia on infarct volume in the rat brain and neurologic deficit. materials and methods: male wistar rats (250-350 g) were divi...

a detailed study of the exploited geothermal field of travale in italy was conducted using magnetotelluric (mt) data in 2004. this paper detects the main features of the conductivity structures of this area. for subsurface mapping purpose, the long period natural-field mt method proved very useful. for processing and modeling of the mt data, 2d inversion schemes were used and to have the best p...
