OBJECTIVE To investigate the influence of BCG vaccination or revaccination on tuberculin skin test reactivity, in order to guide the correct interpretation of this test in a setting of high neonatal BCG vaccination coverage and an increasing BCG revaccination coverage at school age. METHODS We conducted tuberculin skin testing and BCG scar reading in 1 148 children aged 7-14 years old in the ...

A high-performance liquid chromatographic (HPLC) method and a cyclodextrin-modified micellar electrokinetic chromatographic (CD-MEKC) method were developed to separate and determine oleanolic acid (OA) and ursolic acid (UA) in Prunella vulgaris. HPLC separations were carried out on a Hedera ODS C18 column with methanol -H2Oacetic acid (85:15:0.3, v/v/v) as mobile phase at a flow-rate of 0.8 ml ...

We measured steady state capillary hydrostatic pressure (P c,i), plasma and lymph protein concentrations, lymph and blood flow, and capillary filtration coefficients in an in situ loop of cat small intestine at venous outflow pressures (PV) of 0, 5, 10, 15, 20, 25, and 30 mm Hg. The data were used to calculate colloid osmotic pressure of lymph and plasma, interstitial fluid pressure (Pt), pre- ...

OBJECTIVES To describe the thickness of mesorectal fat in local Chinese population and its impact on rectal cancer staging. DESIGN Case series. SETTING Two local regional hospitals in Hong Kong. PATIENTS Consecutive patients referred for multidisciplinary board meetings from January to October 2012 were selected. MAIN OUTCOME MEASURES Reports of cases that had undergone staging magnetic...

BACKGROUND In children, the incidence of injection pain at i.v. anaesthetic induction with Etomidate-Lipuro is low when compared with propofol mixed with lidocaine (5%). However, the incidence of involuntary myoclonic movements (MM) after induction of anaesthesia is higher compared with propofol (85% vs. 15%). In adults, the incidence of MM is reported to be significantly reduced if a small pri...

Background and Objectives: Desiccation is a necessary procedure to eliminate moisture from foodstuffs in industries, especially pharmaceutical, food and tobacco industries. In the present study, a mathematical modeling was assessed for vacuum drying of the licorice roots. Materials and Methods: Fresh licorice roots were dried at 50 mbar. Temperatures included 22to 150°C and diameters of roots ...
