BACKGROUND The present study analyzed whether or not the in vitro cultivation for long periods of time of pre-isolated Leishmania amazonensis from lesions of chronically infected BALB/c mice was able to interfere in the parasites' infectivity using in vivo and in vitro experiments. In addition, the proteins that presented a significant decrease or increase in their protein expression content we...

Spatial and temporal variability in precipitation has been dramatically changed due to climate change over the global domain. Increasing extreme events are pronounced various regions, including monsoon Asia (MA) recent decades. The present study evaluated light of intensity, duration, frequency with several indices developed by Expert Team on Climate Change Detection Indices (ETCCDI) MA region....

conclusions our study showed that the triple therapy of nd: yag and nd: yag + co2 fractional and hydroquinone cream had high efficiency and low morbidity compared to twofold treatment with nd: yag and nd: yag + co2 fractional. results seventeen patients with melasma (14 females and three males) with mean (± sd) age of 38.47 (± 6.29) years (range 29 - 53) were included in this study. the only si...

abstract background prevention of myocardial siderosis is a key step to reduce rate of mortality in thalassemic patients. our objective was to study association between echocardiography parameters and serum ferritin level in patients with major thalassemia. materials and methods sixty-six patients with major thalassemia were studied in amir kabir hospital, arak, iran. serum ferritin levels were...

in order to know the environmental behaviour of toxic pollutants it is fundamental to understandthe role of chemical components of a material on sorption of such pollutants.in this study, the sorption of amix of polycyclic aromatic hydrocarbons (pahs) by cork fractions (i.e. raw cork (cf), free extractive cork(fef) and nonsaponifiable (desf)) has been investigated to better understand the role ...

Sustained muscle wasting due to immobilization leads to weakening and severe metabolic consequences. The mechanisms responsible for muscle recovery after immobilization are poorly defined. Muscle atrophy induced by immobilization worsened in the lengthened tibialis anterior (TA) muscle but not in the shortened gastrocnemius muscle. Here, we investigated some mechanisms responsible for this diff...

We have characterized 14 human colorectal carcinoma cell lines established from primary and metastatic sites by us during the years 1982 to 1985. Five lines were established in fully defined ACL-4 medium and 9 in serum supplemented R10 medium. However, after establishment, cultures could be grown interchangeably in either medium. The lines grew as floating cell aggregates in ACL-4 medium, while...

For most ecosystems, net ecosystem exchange of CO2 (NEE) varies within and among years in response to environmental change. We analyzed measurements of CO2 exchange from eight native rangeland ecosystems in the western United States (58 site-years of data) in order to determine the contributions of photosynthetic and respiratory (physiological) components of CO2 exchange to environmentally caus...
