This paper examines the vulnerability of the Congo Basin's forests through a GIS platform, taking into consideration the variables of population growth, road density, logging concession, and forest fragmentation. The assessment indicates that the forests will continue to shrink towards the interior over the next 50 years. Current contiguous forests will fragment into three large blocks, includi...

ZnFe2O4 was fabricated by a simple solution-combustion method. The structural, optical and electronic properties are investigated by XRD, TEM, FESEM, UV-vis DRS, PL, FTIR and photocurrent measurements. The photocatalytic activity of the prepared material is studied with regard to the degradation of rhodamine B (Rh B) and Congo red under solar irradiation. The kinetic study showed that the mater...

An alternative method for detecting the production of slime by coagulase negative staphylococci was compared with the routinely used Christensen method on 124 isolates of coagulase negative staphylococci from carriage sites, blood cultures, and infected peritoneal dialysis fluids. The alternative method requires the use of a specially prepared solid medium--brain heart infusion broth, supplemen...

Congo red staining is rarely the source of false positives for amyloid. On the other hand, the heat artifact due to cautery in surgical specimens adopts some hyaline features, which can mimic amyloid deposits many times. Therefore, we decided to investigate the behavior of these artifacted areas with some of the ancillary techniques that are commonly used when diagnosing amyloidosis: Congo red ...

The monotypic genus Trichobatrachus, with its sole representative, the hairy frog, Trichobatrachus robustus Boulenger, 1900, could be considered one of the most well-known frogs of Africa. Despite its broad recognition and the fact that it is considered wide-spread and locally common (Amiet & Burger 2004), surprisingly little is known about the actual distribution and the specific occurrence pa...

since 1999, many cases of crimean-congo hemorrhagic fever have been reported from different parts of iran. this study intended to define cchf seroprevalence, incidence rates, and the most important risks in sistan- baluchestan province, iran. using cluster sampling with probability proportional to size, 310 subjects were selected from various districts of zahedan and zabol in the northern part ...

background: crimean-congo hemorrhagic fever (cchf) is a disease characterized by serious course, including acute viral fever, ecchymosis, thrombocytopenia, liver dysfunction and high rate of mortality. hypoxia inducible factor-1α (hif-1α) and vascular endothelial growth factor-a (vegf-a) play an important role both in the inflamma­tory process and plasma leakage. the aim of this study was to de...

case presentation this article presents a 56-year-old woman from guilan province, the north of iran and the southern coast of the caspian sea, who admitted to the hospital with acute fever, severe headache, thrombocytopenia, anemia, epigastric pain, myalgia, nausea and vomiting. conclusions we recognized that the case was co-infected by cchf and leptospirosis. introduction infectious diseases a...

in this work, the adsorption of the anionic dye, congo red (cr), from aqueous solution by using tea waste (tw) has been carried out at 30 °c. the equilibrium sorption isotherms and kinetics were investigated. the equilibrium adsorption was studied by the langmuir and freundlich models of adsorption. the experimental results manifested that the langmuir isotherm was the best model for the adsorp...

amyloidosis cutis dyschromica (acd) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. five other members of her family are also involved. biopsy of hyperpigmented lesions revealed increase of melanin in the basal layer, pigment incontinence and amorpho...
