Global warming is increasing the vulnerability of ecosystems, especially in peninsular Spain. Biosphere Reserves are internationally protected areas that seek to protect biodiversity and, at the same time, promote sustainable development. Evaluating these protected areas is essential to verify environmental changes and establish priorities in their management.

However, microRNAs' concurrent participation in syngeneic mouse B16F1 melanoma cells simultaneously induced decreased proliferation and differential pigmentation by exposure to 5-Brd-2'-dU (5'Bromo-2-deoxyuridine) and L-Tyr (L-Tyrosine) respectively, is poorly understood. : To evaluate changes in the expression of microRNAs and identify which miRNAs in-network may contribute to the functional bases of phenotypes of differential pigmentation and reduction of proliferation in B16F1 melanoma cells exposed to 5-Brd-2'-dU and L-Tyr.

Little is known about the molecular basis of the influence of external carbon/nitrogen (C/N) ratio and other abiotic factors on phytohormones regulation during seed germination and plant developmental processes, and the identification of elements that participate in this response is essential to understand plant nutrient perception and signaling. Sugars (sucrose, glucose) and nitrate not only act as nutrients but also as signaling molecules in plant development. A connection between changes in auxin transport and nitrate signal transduction has been reported in Arabidopsis thaliana through the NRT1.

Intensive research regarding the pathogenesis of EWS has been insufficient to pinpoint the early events of Ewing sarcomagenesis. However, the Mesenchymal Stem Cell (MSC) is currently accepted as the most probable cell of origin.

Yet the potential for regulation at the transcriptional level has not been fully investigated. Here, we studied the relationship between seed viability, gene expression and glutathione redox status during artificial ageing of pea (Pisum sativum) seeds.

The purpose of this study was to summarize our experiences and lessons learned in trying to integrate information from a web-based diabetes self-management program into primary care and the electronic health record (EHR). We describe plans, implementation, adaptations made, and data on patient and physician reactions to the My Path diabetes self-management program provided to 331 adult primary care patients.

However, our knowledge is still limited about the regulatory mechanisms that coordinate and modulate the different pathways providing substrates during xylogenesis. The development of compression wood in conifers constitutes an exceptional model for these studies.
View Article and Find Full Text PDFLatinas with type 2 diabetes are in need of culturally sensitive interventions to make recommended longterm lifestyle changes and reduce heart disease risk. To test the longer-term (24-month) effects of a previously successful, culturally adapted, multiple-healthbehavior- change program, ¡Viva Bien!, 280 Latinas were randomly assigned to usual care or ¡Viva Bien!. Treatment included group meetings to promote a culturally adapted Mediterranean diet, physical activity, supportive resources, problem solving, stress-management practices, and smoking cessation.
View Article and Find Full Text PDFObjective: To inform the refinement of a culturally adapted diabetes intervention, we evaluated acculturation's association with variables at several sequential steps: baseline measures of diet and physical activity, intervention engagement, putative mediators (problem solving and social resources), and outcomes (fat consumption and physical activity).
Method: Latina women (N = 280) recruited from health organizations were randomly assigned to a culturally adapted lifestyle intervention (¡Viva Bien!) or usual care. A brief version of the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) acculturation scales (Anglo and Latina orientations) was administered at baseline.
The early transcriptional defense responses and reactive oxygen species (ROS) production in Arabidopsis (Arabidopsis thaliana) cell suspension culture (ACSC), containing functional chloroplasts, were examined at high light (HL). The transcriptional analysis revealed that most of the ROS markers identified among the 449 transcripts with significant differential expression were transcripts specifically up-regulated by singlet oxygen ((1)O(2)). On the contrary, minimal correlation was established with transcripts specifically up-regulated by superoxide radical or hydrogen peroxide.

Purpose: The purpose of this study was to test a cultural adaptation of a successful multiple health behavior change program, ¡Viva Bien!
Methods: Random assignment of 280 Latinas with type 2 diabetes to usual care only or to usual care + ¡Viva Bien!, which included group meetings for building skills to promote the Mediterranean diet, physical activity, stress management, supportive resources, and smoking cessation.
Results: ¡Viva Bien! participants compared to usual care significantly improved psychosocial and behavioral outcomes (fat intake, stress management practice, physical activity, and social-environmental support) at 6 months, and some improvements were maintained at 12 months.
The transition from vegetative growth to reproduction is a major developmental event in plants. To maximise reproductive success, its timing is determined by complex interactions between environmental cues like the photoperiod, temperature and nutrient availability and internal genetic programs. While the photoperiod- and temperature- and gibberellic acid-signalling pathways have been subjected to extensive analysis, little is known about how nutrients regulate floral induction.

This study evaluated minimal and moderate support versions of an Internet-based diabetes self-management program, compared to an enhanced usual care condition.
Research Design And Methods: A three-arm practical randomized trial was conducted to evaluate minimal contact and moderate contact versions of an Internet-based diabetes self-management program, offered in English and Spanish, compared to enhanced usual care.

Objectives: To explore issues of intervention tailoring for ethnic minorities based on information and experiences shared by researchers affiliated with the Health Maintenance Consortium (HMC).
Methods: A qualitative case study methodology was used with the administration of a survey (n = 17 principal investigators) and follow-up telephone interviews. Descriptive and content analyses were conducted, and a synthesis of the findings was developed.
Bone and soft tissue sarcomas are an infrequent and heterogeneous group of mesenchymal tumors including more than a hundred different entities attending to histologic patterns. Research into the molecular aspects of sarcomas has increased greatly in the last few years. This enormous amount of knowledge has allowed, for instance, to refine the classification of sarcomas, improve the diagnosis, and increase the number of therapeutical targets available, most of them under preclinical evaluation.

Ewing sarcoma family tumors (ESFT) are a group of aggressive solid bone and soft tissue malignancies of children and young adults characterized by specific chromosomal translocations that give rise to EWS-ETS aberrant transcription factors. Identification of EWS-ETS target genes and their role in tumor signaling networks together with the unravelling of the cell of origin will facilitate the translation into new treatment modalities for these neoplasms.

Research Design And Methods: Baseline data from a type 2 diabetes self-management randomized trial with 463 adults having elevated BMI (M = 34.8 kg/m(2)) were used to investigate relations among demographic, psychosocial, and social-environmental variables; dietary, exercise, and medication-taking behaviors; and biologic outcomes.
Because Latinas experience a high prevalence of type 2 diabetes and its complications, there is an urgent need to reach them with interventions that promote healthful lifestyles. This article illustrates a sequential approach that took an effective multiple-risk-factor behavior-change program and adapted it for Latinas with type 2 diabetes. Adaptation stages include (a) information gathering from literature and focus groups, (b) preliminary adaptation design, and (c) preliminary adaptation test.

Elucidation of EWS/ETS target gene networks within the context of other signaling pathways, together with the identification of the initiating cell, and the development of genetically engineered mice will hopefully lead to biology-based therapeutic strategies for these tumors.

Ewing sarcoma translocations fuse the EWS gene with an ETS transcription factor, mainly FLI1. Most of the EWS-FLI1 target genes still remain unknown and many have been identified in heterologous model systems.
