background fever of unknown origin (fuo) is defined as the presence of fever in a child for eight or more days that a careful history and physical examination and preliminary laboratory results failed to reveal the probable cause of the fever. the causes of fuo are different according to geographical regions and age. objectives the current study aimed to evaluate the common causes of childhood ...
Aim We compare different scenarios for the origin of the endemic western Mediterranean species of aquatic Coleoptera of the “Haenydra” lineage (Hydraenidae, Hydraena) through contrasting predictions of the relationship between their phylogenetic and geographic distance. We test whether species originated 1) through successive periods of dispersal and speciation, or through fragmentation of the ...
Recently, the geographical origins of Ashkenazic Jews (AJs) and their native language Yiddish were investigated by applying the Geographic Population Structure (GPS) to a cohort of exclusively Yiddish-speaking and multilingual AJs. GPS localized most AJs along major ancient trade routes in northeastern Turkey adjacent to primeval villages with names that resemble the word "Ashkenaz." These find...
OBJECTIVE Gut microbiome dysbiosis is associated with numerous diseases, including type 1 diabetes. This pilot study determines how geographical location affects the microbiome of infants at high risk for type 1 diabetes in a population of homogenous HLA class II genotypes. RESEARCH DESIGN AND METHODS High-throughput 16S rRNA sequencing was performed on stool samples collected from 90 high-ri...
To estimate trends in tuberculosis (TB) notification rates by geographical origin, we retrieved surveillance data from 2010 to 2015 for 29 European Union and European Economic Area countries. The TB notification rate decreased at an annual rate of 5.3%. The decrease in notification rate was higher in native residents (7.0%) than in those of foreign origin (3.7%). Targeted screening and facilita...
In this study we analysed mineral composition of bee pollen of different plant origin collected across Serbia using inductively coupled plasma - optical emission spectrometry. The most abundant elements were potassium, calcium, and magnesium. The samples were also exceptionally rich in iron and zinc, which are very important as nutrients. Judging by our findings, mineral composition of bee poll...
This study examines ethnic differences in leaving the parental home and the choice of destination (both location and quality of housing) in the Netherlands. Using unique individual administrative panel data, we study the mobility of the entire birth cohort 1983. In contrast to previous studies, this paper includes the geographical location and the quality of destination living arrangements in t...
This work discusses the determination of the provenance of commercial Torrontés wines from different Argentinean provinces (Mendoza, San Juan, Salta and Rio Negro) by the use of UV-vis spectroscopy and chemometric techniques. In order to find classification models, wines (n = 80) were analyzed using UV-Vis region of the electromagnetic spectrum. Principal component analysis (PCA), linear discri...
Geographic Proximity, Trade and International Conflict/Cooperation This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically close, but has a greater effect on coo...
