It is reported that bacterial colonization of the airway in neonates affects the likelihood and severity of subsequent wheezing in childhood. This study aimed to explore the impact of bacterial colonization on the severity of virus-induced wheezing, and accompanying airway inflammation. Nasopharyngeal aspirates (NPAs) from 68 hospitalized children with(More)
The biological behavior of fullerene derivatives shows their considerable potential for medical applications. In order to provide a C(60) derivative for biodistriburtion studies, the (99m)Tc-labeling of C(60)(OH)(x) was optimized. Gamma counting and single photon emission computed tomography (SPECT) were used to assess the biodistribution of the(More)
Lettuce canopy spectral reflectance was measured by hand-held portable spectrum analyzer, the reflectance characteristics was analyzed in the different nitrogen levels and different growth. After the first derivative treatment, then correlation analysis, lettuce canopy nitrogen associated with the four-sensitive band ,which were 400 ∼ 470nm, 510(More)
BACKGROUND Mold contamination of grains not only contributes to inedible food, resulting in economic losses, but also leads to mold in humans and livestock, and can even be carcinogenic to them. Rice, as one of the main grain varieties, if stored improperly, is easily susceptible to mildew. In order to detect the total number of mold colonies in rice more(More)
OBJECTIVES Valganciclovir 900 mg/day is approved for cytomegalovirus (CMV) prophylaxis, but 450 mg/day is seems also effective. We systematically reviewed the efficacy and safety of low-dose versus high-dose valganciclovir prophylaxis in renal transplantation recipients. METHODS An electronic search was conducted up to November 29, 2016. The primary(More)
Fast identification of pesticide residue level in lettuce leaves plays a key role in the test of food safety. In order to identify the different concentrations pesticide residues of lettuce leaves in a fast and nondestructive way, the hyperspectra coupled with chlorophyll fluorescence spectra was used in this research. Transmission electron microscopy (TEM)(More)
