BACKGROUND The Institute of Medicine set a tolerable upper intake level (UL) for usual daily total folic acid intake (1,000 µg). Less than 3% of US adults currently exceed the UL. OBJECTIVE The objective of this study was to determine if folic acid fortification of corn masa flour would increase the percentage of the US population who exceed the UL. DESIGN We used dietary intake data from N...

A method is given for calculation of a distribution of small particles, embedded in a medium, so that the resulting medium would have a desired radiation pattern for the plane wave scattering by this medium.

0.1. Let g be a semi-simple Lie algebra. Given a root of unity (cf. Sect. 1.2), one can consider two remarkable Hopf algebras, Ul and ul, called the big and the small quantum group, respectively. Let Ul -mod and ul -mod denote the corresponding categories of modules. It is explained in [14] and [1] that the former is an analog in characteristic 0 of the category of algebraic representations of ...

BACKGROUND Iterative reconstruction methods have attracted attention for reducing radiation doses in computed tomography (CT). PURPOSE To investigate the detectability of pancreatic calcification using dose-reduced CT reconstructed with model-based iterative construction (MBIR) and adaptive statistical iterative reconstruction (ASIR). MATERIAL AND METHODS This prospective study approved by ...

The prevailing view of upper-layer (UL) neurogenesis in the cerebral cortex is that progenitor cells undergo successive rounds of asymmetric cell division that restrict the competence and production of UL neurons later in development. However, the recent discovery of UL fate-committed early progenitors raises an alternative perspective concerning their ontogeny. To investigate the emergence of ...

uterine leiomyoma (ul) is the most common benign smooth muscle cell tumor with as yet unknown etiology and pathogenesis. this study was carried out to investigate the association of esr1-351 a>g, esr1 -397 t>c and cyp1a1 (ile462val) polymorphisms with ul in female patients of iranian origin. in this case-control study, 276 patients with ul and 156 healthy women were recruited. the genetic polym...

Rates of uterine leiomyomata (UL) are 2–3 times higher in African Americans than in European Americans. It is unclear whether inherited factors explain the ethnic disparity. To investigate the presence of risk alleles for UL that are highly differentiated in frequency between African Americans and European Americans, the authors conducted an admixture-based genome-wide scan of 2,453 UL cases co...

To elucidate whether any relationship exists between ovarian blood flow and ovulation rate, the effects on these parameters were examined in equine chorionic gonadotrophin/human chorionic gonadotrophin (eCG/HCG) (15I U/15I U) primed rats after bilateral ligation and severance of either the ovarian branch of the uterine artery and vein (UL), the ovarian artery and vein (OL) or both sites (UL+OL)...

Mazhar ul Islam is one of the leading authors contemporary Urdu literature. Due to romantic, realist, surrealist, and symbolist concepts used in his works, author's style, which allows contrasting or incompatible interpretations be harmonized, described as most important feature. The events characters stories are generally a literary reflection Pakistani society. At same time, author does not h...

OBJECTIVES To investigate whether a priori selection of patient records using unexpectedly long length of stay (UL-LOS) leads to detection of more records with adverse events (AEs) compared to non-UL-LOS. DESIGN To investigate the opportunities of the UL-LOS, we looked for AEs in all records of patients with colorectal cancer. Within this group, we compared the number of AEs found in records ...
