Angioedema: a rare and sometimes delayed side effect of angiotensin-converting enzyme inhibitors.

The effects of angiotensin converting enzyme (ACE) inhibitors result from the inhibition of the ACE (kininase II) to ultimately influence both the renin-angiotensin system and the degradation of the bradykinin (BK) metabolism. ACE inhibitors block the degradation of BK and substance P by ACE. In addition, an active metabolite of BK (Des-Arg9-BK) is catalysed by kininase I and its degradation is controlled in part by the conversion enzyme.

Sexual Cognitions, Trait Anxiety, Sexual Anxiety, and Distress in Men With Different Subtypes of Premature Ejaculation and in Their Partners.

This study examined trait anxiety and sexual cognitions in 610 men with premature ejaculation (PE) (DSM-IV-TR criteria) and in 107 partners of these men, and compared their scores to normative data. Sexual anxiety, intravaginal ejaculatory latency time, feeling of control over ejaculation, and PE-related distress were also assessed. The scores of 343 participants (56.

A Nonrandomized Comparison Study of Self-Hypnosis, Yoga, and Cognitive-Behavioral Therapy to Reduce Emotional Distress in Breast Cancer Patients.

The authors asked breast cancer (BC) patients to participate in 1 of 3 mind-body interventions (cognitive-behavioral therapy (CBT), yoga, or self-hypnosis) to explore their feasibility, ease of compliance, and impact on the participants' distress, quality of life (QoL), sleep, and mental adjustment. Ninety-nine patients completed an intervention (CBT: n = 10; yoga: n = 21; and self-hypnosis: n = 68). Results showed high feasibility and high compliance.

Heat can erase epigenetic marks of vernalization in Arabidopsis.

Vernalization establishes a memory of winter that must be maintained for weeks or months in order to promote flowering the following spring. The stability of the vernalized state varies among plant species and depends on the duration of cold exposure. In Arabidopsis thaliana, winter leads to epigenetic silencing of the floral repressor gene FLOWERING LOCUS C (FLC) and the duration of cold is measured through the dynamics of chromatin modifications during and after cold.

Identification of Differential Item Functioning in Multiple-Group Settings: A Multivariate Outlier Detection Approach.

We focus on the identification of differential item functioning (DIF) when more than two groups of examinees are considered. We propose to consider items as elements of a multivariate space, where DIF items are outlying elements. Following this approach, the situation of multiple groups is a quite natural case.

The effects of happy and angry expressions on identity and expression memory for unfamiliar faces.

We investigated the influence of happy and angry expressions on memory for new faces. Participants were presented with happy and angry faces in an intentional or incidental learning condition and were later asked to recognise the same faces displaying a neutral expression. They also had to remember what the initial expressions of the faces had been.
