The last deglaciation was characterized by a sequence of abrupt climate events thought to be linked rapid changes in Atlantic meridional overturning circulation (AMOC). includes weakening the AMOC after Last Glacial Maximum (LGM) during Heinrich Stadial 1 (HS1), which ends with an amplification at transition Bølling/Allerød (B/A). This occurs despite persistent deglacial meltwater fluxes that c...

introduction: the magnocellular neurons (mcns) of the supraoptic nucleus (son) play a crucial role in control of physiological and pathophysiologiccal condition due to two peptides that they synthesize, i.e. oxytocin (oxt) and vasopressin (avp). the activity of mcns is regulated by a variety of excitatory and inhibitory inputs. opioid receptors are one of the important receptors in son synapses...

background hepatitis c virus (hcv) is a major cause of chronic liver disease worldwide. the role of intra familial hcv transmission is still controversial. the aim of the present study is to determine intra familial transmission (sexual and non sexual contacts) of hcv in a group of iranian population. patients and methods in this historical cohort study, 270 first degree relatives of hepatitis ...

the aim of this study was to investigate the prevalence of hepatitis b virus (hbv) genotypes in isparta, southwest of turkey, as well as the clinical features and transmission route for patients with hbv infections. methods: patients (n = 135) with hbv infection were included in the study. epidemiological and clinical data were obtained. hbv genotypes were determined with a pres2 epitope elisa ...

The characterization of Last Glacial millennial-timescale warming phases, known as interstadials or Dansgaard-Oeschger events, requires precise chronologies for the study of paleoclimate records. On the European continent, such chronologies are only available for several Last Glacial pollen and rare speleothem archives principally located in the Mediterranean domain. Farther north, in continent...

in the recent issue of middle east journal of digestive diseases, we read with great interest the article by bahari et al. 1 , “significance of response to hepatitits b vaccine in subjects with isolated antibody to hepatitis b core antigen”. we wanted to specify some important matters related to the article.

background : main technique to control acquired immunodeficiency syndrome (hiv) infection is the effective preventive programs among high-risk groups. modeling is one of the effective methods where there is inadequate data. we used the modes of transmission (mot) model to predict the transmission of hiv infection in iran. methods : we systematically searched published and grey literature to fin...

background: the household transmission of hepatitis b virus (hbv) is a major health problem. high incidence of hbv infection is observed within the household contacts of hbv carriers. we aimed to evaluate serological markers of hepatitis b infection among family members of hbv carriers in arak, central iran. methods: data were collected from the 100 chronic hbv carriers (subjects with positive ...
