OBJECTIVE To establish reference standards for percentage body fat measured in Hong Kong Chinese children, by methods involving bioelectrical impedance analysis. DESIGN Cross-sectional study. SETTING Thirty-six randomly selected primary and secondary schools and a teaching hospital in Hong Kong. PARTICIPANTS A total of 14 842 students randomly selected from the schools and two additional ...

background: the occurrence and the mortality related to breast cancer (bc) in iranian female population has increased over time. although there are many studies on bc and related risk factors, however, the epidemiological aspects of this melanoma in iranian females are uncertain. therefore, the aim of this study was to determine the relationship between demographical and clinical factors on the...

MIC and disk diffusion quality control (QC) ranges were established for two new pleuromutilin antimicrobials (BC-3205 and BC-3781) in an eight-laboratory study performed according to Clinical and Laboratory Standards Institute M23-A3 guidelines. Staphylococcus aureus ATCC 29213 and 25923, Streptococcus pneumoniae ATCC 49619, and Haemophilus influenzae ATCC 4927 strains were evaluated. The propo...

following the rise of darius i to power in 522 bc, many of countries became rebellious against him. three of nine of those revolts which took place in first and second years of darius was in elam. in this paper it has been tried based on texts, in particular bisitun inscription and new research and by using historical method of research to examine the nature of elamite uprising against darius. ...

Clopidogrel is a prodrug that needs to be converted to its active metabolite (clopi-H4) in two sequential cytochrome P450 (P450)dependent steps. In the present study, a dynamic physiologically based pharmacokinetic (PBPK) model was developed in Simcyp for clopidogrel and clopi-H4 using a specific sequential metabolite module in four populations with phenotypically different CYP2C19 activity (po...

The X-ray source known as GRS1915+105 belongs to a group dubbed `microquasars'. These objects are binary systems which sporadically eject matter at speeds that appear superluminal, as is the case for some quasars. GRS1915+105 is also one of only two known binary sources thought to contain a maximally spinning black hole. Determining the basic parameters of GRS195+105, such as the masses of the ...

This document includes some mathematical notions I will assume. Most of these are taught in a discrete math class, and in any case are not complicated and easy to pick up. You can read it at your own pace — it will take a few weeks until we’ll get to use all of this stuff. You do not have to do the exercises, and in any case don’t need to submit them. If you feel you’d like more clarifications ...

Mikrocytos mackini, causative agent of Denman Island disease in Pacific oysters Crassostrea gigas and other oyster species, was found in 2011 in a previously unreported host, the Kumamoto oyster C. sikamea, in Humboldt Bay, California, USA. The detection was also the first reported finding of M. mackini in California. Prevalence was estimated as high as approximately 27% from pooled samples ana...

Peng et al. (1) conclude that a fast increase in the mass absorption cross-section (MAC) of black carbon (BC) in urban environments leads to significantly increased estimates of the BC radiative forcing (RF). Their chamber measurements are highly valuable and complement observations performed in ambient conditions, but their “enhancement factor” relative to an unspecified baseline may not be di...
