The human cytosolic sulfotransfases ( hSULTs ) comprise a family of 12 phase II enzymes involved in the metabolism of drugs and hormones , the bioactivation of carcinogens , and the detoxification of xenobiotics . Knowledge of the structural and mechanistic basis of substrate specificity and activity is crucial for und... | We metabolize many hormones , drugs , and bioactive chemicals and toxins from the environment . One family of enzymes that participate in the metabolic process consists of the cytosolic sulfotransferases , or SULTs . SULTs have a variety of mechanisms of action—sometimes they inactivate the biological activity of the c... | [

In all vertebrates hearing and touch represent two distinct sensory systems that both rely on the transformation of mechanical force into electrical signals . There is an extensive literature describing single gene mutations in humans that cause hearing impairment , but there are essentially none for touch . Here we fi... | In humans many genes have been identified that cause deafness when mutated , but no equivalent genes have been identified that are required for touch . Here , we asked whether genes that influence hearing can also influence touch . Using identical and non-identical human twins it was possible to show that touch perform... | [

Historically the western sahelian dry regions of Mali are known to be highly endemic for cutaneous leishmaniasis ( CL ) caused by Leishmania major , while cases are rarely reported from the Southern savanna forest of the country . Here , we report baseline prevalence of CL infection in 3 ecologically distinct districts... | It is generally assumed that neglected tropical diseases ( NTDS ) such as leishmaniasis are concentrated in poor populations . It affects as many as 12 million people , with 1 . 5 to 2 million new cases every year around the world . Depending on the species of Leishmania , the host can develop cutaneous leishmaniasis (... | [

Modelling disease dynamics is most useful when data are limited .

Mounting evidence suggests that Q-fever is more prevalent in Iran than originally believed . However , in most parts of the country , clinicians do not pay enough attention to Q fever in their differential diagnosis . The aim of this study was to investigate the prevalence of Coxiella burnetii in suspected cases of acu... | Q fever is a zoonotic infectious disease caused by Coxiella burnetii .
