Vitamin A equivalency of β-carotene (VEB) is defined as the amount of ingested β-carotene in μg that is absorbed and converted into 1 μg retinol (vitamin A) in the human body. The objective of the present review was to discuss the different estimates for VEB in various types of dietary food matrices. Different methods are discussed such as mass balance, dose-response and isotopic labelling. The...

bla(VEB-6) was found on the Proteus mirabilis chromosome in a context similar to those of bla(VEB-1a) and bla(VEB-1b), in a truncated gene cassette flanked by 135-bp elements and duplications of the 3'-conserved segment of class 1 integrons. A linked aacA4-aadB-dfrA1-orfC cassette array includes components of Tn1331, illustrating the complex mosaicism of multiresistance regions.

Over a 4-month period from November 2002 to February 2003, 27 ceftazidime-resistant or cefotaxime-resistant nonrepetitive Enterobacter cloacae isolates were collected from 27 patients hospitalized at HuaShan Hospital, Shanghai, People's Republic of China. The Etest did not detect extended-spectrum beta-lactamases (ESBLs) in those 27 isolates; however, screening by the NCCLS ESBL disk test and c...

BACKGROUND The inter-patient classification schema and the Association for the Advancement of Medical Instrumentation (AAMI) standards are important to the construction and evaluation of automated heartbeat classification systems. The majority of previously proposed methods that take the above two aspects into consideration use the same features and classification method to classify different c...

Ceftazidime-avibactam has activity against Pseudomonas aeruginosa and Enterobacteriaceae expressing numerous class A and class C β-lactamases, although the ability to inhibit many minor enzyme variants has not been established. Novel VEB class A β-lactamases were identified during characterization of surveillance isolates. The cloned novel VEB β-lactamases possessed an extended-spectrum β-lacta...

AIMS To test the hypothesis that the QS interval of ventricular ectopic beats (VEBs) (ventricular ectopic QS interval, VEQSI) would provide a marker for the presence of structural heart disease and a predictor of mortality. METHODS AND RESULTS We interviewed and examined 2332 patients undergoing Holter ECG monitoring for clinical indications. In persons with VEBs, the morphologies were counte...

The purpose of this study was to determine if combining velocity-based training with eccentric focus (VEB) and velocity-based training (VBT) results in power and strength gains. Nineteen men and women collegiate track and field athletes participated in this study. The subjects completed a 12-week intervention with either a VEB program or a VBT program. To determine the effectiveness of each pro...

BACKGROUND Frequent ventricular ectopic beats (VEB) in patients without significant cardiac disease are usually classified as benign arrhythmia. However, they may alter cardiac performance. RF ablation can effectively eliminate VEB. AIM To evaluate the effects of RF ablation on selected haemodynamic parameters of left ventricular (LV) systolic and diastolic function and exercise capacity in p...

Tema rada jeste primena sinemagrafa kao elementa veb-stranice koji doprinosi kako praktič­nosti pružanja neophodnih informacija tako i estetici veb-sajta, odnosno ispitivanje efektivnosti tehno­logijom za praćenje pokreta očiju. Cilj istraži­vanje da li se korisnici sajta duže zadržavaju na pokret­nim elementima u odnosu statičnu sliku identičnog sadržaja, ponovo vraćaju pokretni sadržaj, ispit...

Joe Colletti, Steven Hoff, Janette Thompson and John Tyndall Iowa State University Abstract In Iowa at a commercial poultry facility, we are assessing the ability of a multi-row vegetative environmental buffer (VEB) to mitigate odor, ammonia, and particulates. In 2004 and 2005 Eastern redcedar (Juniperius virginiana), hybrid willow (Salix X) and limber pine (Pinus flexilis) were planted in rows...
