concentrations of 42 trace elements, including rare earths, in croatian thermal waters wereinvestigated. originating from different parts of croatia, i.e. different types of aquifers, studied thermal watersprovide insight into the range of concentrations of broad spectrum of elements in croatian thermal waters.covering a wide range of temperature (30 - 92 °c), studied thermal waters are general...
Extreme climatic conditions and their ecological impacts are currently emerging as critical features of climate change. We studied extreme sea ice condition (ESIC) and found it impacts both life-history traits and population dynamics of an Antarctic seabird well beyond ordinary variability. The Southern Fulmar (Fulmarus glacialoides) is an ice-dependent seabird, and individuals forage near the ...
BACKGROUND A relative inability to capture a sufficiently large patient population in any one geographic location has traditionally limited research into rare diseases. METHODS AND RESULTS Clinicians interested in the rare disease lymphangioleiomyomatosis (LAM) have worked with the LAM Treatment Alliance, the MIT Media Lab, and Clozure Associates to cooperate in the design of a state-of-the-a...
Persistence refers to the phenomenon in which isogenic populations of antibiotic-sensitive bacteria produce rare cells that transiently become multidrug tolerant. Whether slow growth in a rare subset of cells underlies the persistence phenotype has not be examined in wild-type bacteria. Here, we show that an exponentially growing population of wild-type Escherichia coli cells produces rare cell...
A high prevalence of rare dopamine receptor D4 (DRD4) alleles in children diagnosed with attention-deficit hyperactivity disorder (ADHD) has been reported [Grady et al., 2003]. In this prior study, extensive resequencing/haplotype data of the DRD4 locus was used to suggest that population stratification was not the explanation for the high prevalence of rare alleles. In the current study, DNA r...
the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
Background Rhabdomyolysis is considered a rare medical condition in pediatric population. Case Report We report our experience on a one year old girl referred to Shiraz Nemazee Hospital, Southern Iran with rhabdomyolysis due to severe hypernatremia, secondary to gastroenteritis. Discussion Rhabdomyolysis should be taken in to consideration in hypernatremic states, as it may lead to severe conse...
Lichen planus pigmentosus, a macular variant of lichen planus, is characterized by slate grey pigmentation and was first seen in the Indian population. We report a case of LPP with a linear distribution. A 27- year-old female presented with asymptomatic dark brown macules from the middle of right calf to the thigh consistent with the pattern of Blaschko’s lines. To the best of our knowledge, th...
Fish tank or swimming granuloma caused by Mycobacterium marinum is an opportunist pathogen commonly found in aquatic environments. We present a 16 year-old boy with frequent exposure to aquarium water who had several nodules (sprotrichoid forms) on his right hand. Pervious studies showed that fish tank granuloma is a rare skin infection (0.27 per 100,000 population in one year). However, t...
A three-member family from Tehran referred with variety of nasopharyngeal symptoms including sneezing, coughing and nasal discharge following consumption of barbecued liver (Kabab). Thirteen worm-like nymphs of Linguatula serrata were separated from larynx, nose and gum of these patients. The adult parasites live in the nose and paranasal sinuses of dogs and other carnivores. Although this in...
