Pterygia are fibrovascular connective tissue overgrowths of bulbar conjunctiva onto the cornea. There is a worldwide distribution of pterygium, but it occurs more commonly in warm, dry climates. Patients younger than the age of 15 rarely acquire a pterygium. We report a case of bilateral nasal pterygium in two siblings. A 10-year-old boy and a 12-year-old girl who are siblings presented with bi...

Anthropogenic climate change is expected to increase global temperatures and potentially increase soil carbon (C) mineralization, which could lead to a positive feedback between global warming and soil respiration. However the magnitude and spatial variability of belowground responses to warming are not yet fully understood. Some of the variability may depend on the native temperature regimes o...

Arsenic (As) is a toxic metalloid which is usually found in rice fields as a contamination and has negative effects on the plant growth and reduces the crop yield. Similar to heavy metals, the deleterious effects of As may be due to, at least in part, the amount of absorbed As and disturbance of the plant water status. I...

Result: Specific IgE antibodies were detected in 29/42 (69%) of all the subjects. The sensitization rate was highest for pollen while results for other allergen groups are as follows: pollen 86/127 (66.9%), animal dander 29/127 (22.8%), HDM 11/127 (8.6%) and moulds 2/127 (1.6%). Among allergenic pollen, mixed grasses were the most common cause of sensitization 14/127 (11.0%). Sensitization rate...

It is challenging to estimate how the regional climate will be shifted under future global warming. To reduce potential risk of shift climates, examining change in features over Asia important, as approximately 60% world's population resides there. In this study, shifts are assessed Asian monsoon region mean temperature warming targets from 1.5°C 5.0°C above preindustrial (PI) levels based on d...

â â â  this paper attempts to investigate the relationship between 500hpa circulation patterns and weather types (coldest, warmest and raining) over 16 synoptic stations of mountainous region of iran. the mountainous region of iran covers about 670000 square kilometer (41 percent) of iran. in this paper have been investigated the relationship between circulation patterns in 500hpa level with we...

The discovery on Mars of recurring slope lineae (RSL), thought to represent seasonal brines, has sparked interest in analogous environments on Earth. We report on new studies of Don Juan Pond (DJP), which exists at the upper limit of ephemeral water in the McMurdo Dry Valleys (MDV) of Antarctica, and is adjacent to several steep-sloped water tracks, the closest analog for RSL. The source of DJP...
