This paper describes a CMOS current-folded direct digital RF quadrature modulator, which uses two 10-bit linear interpolation current steering digital-to-analog converters (DACs) and two current-folded double-balanced mixers. The attenuation of the DAC image components is significantly increased with linear interpolation, and the reconstruction filter is therefore eliminated. The DAC baseband diff

One of the major roles of seminal plasma is to provide antimicrobial protection for the spermatozoa in the female reproductive tract. We found that the bactericidal activity of seminal plasma was highest after resolution of the seminal clot and that this antibacterial activity subsequently became greatly diminished. The antibacterial activity was derived from peptides generated by fragmentation of

Collagenous colitis (CC) is a major cause of chronic non-bloody diarrhoea, particularly in the elderly female population. The aetiology of CC is unknown, and still poor is the understanding of its pathogenesis. This possibly involves dysregulated inflammation and immune-mediated reactions in genetically predisposed individuals, but the contribution of genetic factors to CC is underinvestigated. We

The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential as well as environmental safety. Repeated dose, developmental, and reproductive toxicities were determined to have

PURPOSE: The aim of this study was to test a model proposing that the relationship between personality factors and women's quality of life (QoL) is mediated by degree of depression and the way in which every day activity and general health were appraised. Specifically, the paper addressed the mediating contribution of activity. METHODS: A sample of 488 women, 38 or 50 years old, filled out questio

Background: Relatives of people with a mental illness who live together can experience additional burdens that may require support. A Web-based tool including a psychoeducation module, a diary, and a password-protected forum was developed to support relatives of a person with depression. Objective: The objective of our study was to explore participants' use of the Web-based tool, with focus on the

BACKGROUND: Following a peripheral nerve repair the injured nerve has to re-innervate its original cortical area, a process, which is poorly understood. Errors in this cortical re-innervation have been suggested as one key reason for the generally poor clinical outcome following nerve injuries in the hand. METHOD: Functional magnetic resonance imaging (fMRI) was used to assess cortical reintegrati

OBJECTIVE: To investigate whether Ritgen's maneuver decreases the risk of third- to fourth-degree perineal tears compared with simple perineal support. METHODS: A total of 1,623 nulliparous women in term labor, singleton pregnancy, and cephalic presentation were randomly assigned to Ritgen's maneuver or standard care. Ritgen's maneuver denotes extracting the fetal head, using one hand to pull the
