Local adaptation optimizes photoprotection strategies in a Neotropical legume tree under drought stress.

Photoprotection is a plant functional mechanism to prevent photooxidative damage by excess light. This is most important when carbon assimilation is limited by drought, and as such, it entails a trade-off between carbon assimilation vs stress avoidance. The ecological adaptation of plants to local water availability can lead to different photoprotective strategies.

A Mixed-Methods Study to Examine the Role of Psychosocial Stress and Air Pollution on Hypertension in Mexican-Origin Hispanics.

Purpose: Independent and combined effects of air pollution and psychosocial stressors on hypertension, a risk factor for cardiovascular disease, among Hispanics are not well studied.

Methods: We administered a pilot-tested questionnaire on individual- and neighborhood-level psychosocial stressors, developed with community input, to nearly 2500 individuals from the MD Anderson Cancer Center cohort of Mexican-Americans. We used data from local air quality monitors to estimate individual exposures to ozone (O) and fine particulate matter (PM) for the 12-month period preceding enrollment using inverse distance interpolation.

Forest restoration in a fog oasis: evidence indicates need for cultural awareness in constructing the reference.

Background: In the Peruvian Coastal Desert, an archipelago of fog oases, locally called lomas, are centers of biodiversity and of past human activity. Fog interception by a tree canopy, dominated by the legume tree tara (Caesalpinia spinosa), enables the occurrence in the Atiquipa lomas (southern Peru) of an environmental island with a diverse flora and high productivity. Although this forest provides essential services to the local population, it has suffered 90% anthropogenic reduction in area.

[Chronic migraine as seen by neurologists and patients: results of the CIEN-mig project (III)].

Introduction: Data on the reality of chronic migraine in our clinics are scarce. AIM. To know the frequency of consultation and attitude of the neurologist regarding chronic migraine, and the opinion of patients with this condition.

[Satisfaction of the migraine patient attending neurology clinics: results of CIEN-mig project (II)].

Introduction: Migraine is the most common neurological consultation in our country. AIM. To analyse the satisfaction level of the patient with migraine attending our clinics.

[Approach of neurologists in Spain to migraine: results of the CIEN-mig project (I)].

Introduction: Headache is the most frequent neurological reason for consultation in our country.

Aim: To obtain descriptive data on the approach and satisfaction of the neurologist regarding the diagnosis, burden and management of headaches, and migraine in particular, together with the relationship with primary care physicians (PCP).

Subjects And Methods: A total of 160 neurologists participated and answered electronically five questionnaires during one year.

[False diagnoses of strokes in emergency departments].

Introduction: Diagnosing a stroke can sometimes be difficult. There are a number of mimic conditions that can lead to false diagnoses.

Aim: To examine false diagnoses of acute stroke.

Can a solitary avian species use collective detection? An assay in semi-natural conditions.

Collective detection (e.g., enhanced predator detection through the vigilance of conspecifics) is expected to have evolved particularly in social species.

Water-use efficiency in cork oak (Quercus suber) is modified by the interaction of water and light availabilities.

We studied the interaction of light and water on water-use efficiency in cork oak (Quercus suber L.) seedlings. One-year-old cork oak seedlings were grown in pots in a factorial experiment with four light treatments (68, 50, 15 and 5% of full sunlight) and two irrigation regimes: well watered (WW) and moderate drought stress (WS).

X-linked Emery-Dreifuss muscular dystrophy and vacuoles: an immunohistochemical characterization.

We report a striking abundance of rimmed vacuoles in two brothers with X-linked Emery-Dreifuss muscular dystrophy (X-EDMD) confirmed by the absence of emerin at the muscular nuclear envelope and by genetic analysis showing a new 2-bp deletion in exon 6 of the STA gene at the Xq28 region. Immunohistochemical analysis of the vacuoles revealed expression of dystrophin but not of merosin in the sarcolemma of rimmed vacuoles and absence of amyloid and membrane attack complex (MAC) deposition either in vacuoles or muscle fibers. The presence of rimmed vacuoles can be a histopathological finding in X-EDMD, and the diagnosis should not be excluded in clinically well-defined EDMD patients because of this finding.
