Rigid-body motion is the main source of diffuse scattering in protein crystallography.

The origin of diffuse X-ray scattering from protein crystals has been the subject of debate over the past three decades regarding whether it arises from correlated atomic motions within the molecule or from rigid-body disorder. Here, a supercell approach to modelling diffuse scattering is presented that uses ensembles of molecular models representing rigid-body motions as well as internal motions as obtained from ensemble refinement. This approach allows oversampling of Miller indices and comparison with equally oversampled diffuse data, thus allowing the maximum information to be extracted from experiments.

Verbal abuse and mobbing in pre-hospital care services in Chile.

Objective: to determine the perception of verbal abuse and mobbing and the associated factors of paramedic technicians (nursing assistants) and professionals (nurses, midwives, kinesiologists) in the pre-hospital care areas of three regions in the south of Chile.

Methods: descriptive and correlational study was performed within the professional community and a two-stage sample of the paramedic technician population in three regions. The questionnaire "workplace violence in the health sector" (spanish version) was applied after signing the informed consent.

Effectiveness of personalized face-to-face and telephone nursing counseling interventions for cardiovascular risk factors: a controlled clinical trial.

Objective: to evaluate the effect and gender differences of an innovative intervention involving in-person and telephone nursing counseling to control cardiovascular risk factors (arterial hypertension, dyslipidemia, and overweight), improve health-related quality of life and strengthen self-efficacy and social support in persons using the municipal health centers' cardiovascular health program.

Method: a randomized controlled clinical trial involving participants randomized into the intervention group who received traditional consultation plus personalized and telephone nursing counseling for 7 months (n = 53) and the control group (n = 56). The study followed the Consolidated Standards of Reporting Trials Statement.

Sexual satisfaction in couples in the male and female climacteric stage.

The objective was to describe the sexual life satisfaction of couples in the climacteric stage and determine whether there are differences between the perception of satisfaction and the sex life of each partner. We studied 142 couples obtained by stratified sampling of family health centers, Concepción, Chile. 66% of women and 84% of men reported being very or somewhat satisfied with their sex lives.

[Quality of work life in nursing staff].

This article deals with aspects that are related to work, quality of life, and its relationship with the nursing staff within the Mexican context. Professionals in health areas present alterations that are commonly overlooked and barely dealt with, especially when the person is a woman and, the care they give to patients, families, and/or friends, or community members, precede their own self care. In the case of institutions or work areas, even when the job provides human beings with several benefits, it usually lacks the proper conditions to perform the job, carries negatives aspects or pathological conditions, all which can relate to poor levels of Quality of Life at Work.
