myiasis is an infestation of tissues with larval stage of dipterous flies.  this condition most often affects the skin and may also occur in certain body cavities.  it is mainly seen in the tropics, though it may also be rarely encountered in non-tropical regions.  herein, we present a case of cutaneous furuncular myiasis in an iranian male who had travelled to africa and his condition was fina...

Tropical tree plantations usually consist of a single exotic fast growing species, but recent research describes positive effects on ecosystem functions from mixed tropical tree plantations. In this review, we present the current knowledge of drought resistance of tropical mixed species plantations and summarize preliminary evidence from a tree biodiversity experiment in Panama. Converting mono...

vascular diseases of the brain are the second reason of the death and the first cause of morbidity and disability worldwide. in tropical areas stroke has some particular features related to the nature of torrid zones. there are some special causes of the stroke, mainly infectious, although some of them are non-infectious. the most important etiologies are malaria, tuberculosis, cysticercosis, s...

In seasonally dry tropical forest regions, drought avoidance during the dry season coupled with high assimilation rates in the wet season is hypothesized to be an advantageous strategy for forest trees in regions with severe and long dry seasons. In contrast, where dry seasons are milder, drought tolerance coupled with a conservative resource-use strategy is expected to maximize carbon assimila...

Assessment of satellite precipitation products’ capability for monitoring drought is relatively new in tropical regions. The purpose of this paper is to evaluate the reliability of the Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA) 3B43 product in estimating the standardized precipitation index (SPI) in the Kelantan River Basin, Malaysia from 1998 to 201...

The causes and global context of the North American drought between 1998 and 2004 are examined using atmospheric reanalyses and ensembles of atmosphere model simulations variously forced by global SSTs or tropical Pacific SSTs alone. The drought divides into two distinct time intervals. Between 1998 and 2002 it coincided with a persistent La Niña–like state in the tropical Pacific, a cool tropi...

amoebiasis is one of the most important human diseases in many countries especially in tropical and sub-tropical regions. this study was carried out from august 1999 to february 2002 in order to determine the ratio of entamoeba histolytica / entamoeba dispar in some regions of iran. a total of 16,592 stool samples were randomly collected from different agegroups in central, northern and souther...

Climate change is harming human health, and the magnitude of the harm is increasing. This is especially true in tropical and subtropical regions that are vulnerable to greater intensity, frequency, and duration of extreme weather, such as hurricanes, drought, and increases in heat, as a result of climate change. Nearly all countries situated in the geographic tropics are poor, and therefore hav...

*The rich ecology of tropical forests is intimately tied to their moisture status. Multi-site syntheses can provide a macro-scale view of these linkages and their susceptibility to changing climates. Here, we report pan-tropical and regional-scale analyses of tree vulnerability to drought. *We assembled available data on tropical forest tree stem mortality before, during, and after recent droug...
