Aims: The molecular mechanisms that correlate with gravity perception and signal transduction in the tip of angiosperm primary roots are discussed.

Scope: Gravity provides a cue for downward orientation of plant roots, allowing anchorage of the plant and uptake of the water and nutrients needed for growth and development. Root gravitropism involves a succession of physiological steps: gravity perception and signal transduction (mainly mediated by the columella cells of the root cap); signal transmission to the elongation zone; and curvature response.

During inflammatory events, the induction of immediate-early genes, such as TNF-alpha, is regulated by signaling cascades including the JAK/STAT, NF-kappaB, and the p38 MAPK pathways, which result in phosphorylation-dependent activation of transcription factors. We observed the direct interaction of histone deacetylase (HDAC) 3, a class I histone deacetylase, with MAPK11 (p38 beta isoform) by West-Western-based screening analysis, pull-down assay, and two-hybrid system analysis. Results further indicated that HDAC3 decreases the MAPK11 phosphorylation state and inhibits the activity of the MAPK11-dependent transcription factor, activating transcription factor-2 (ATF-2).

We measured the endocardial convective heat transfer coefficient h at 22 locations in the cardiac chambers of 15 pigs in vivo. A thin-film Pt catheter tip sensor in a Wheatstone-bridge circuit, similar to a hot wire/film anemometer, measured h. Using fluoroscopy, we could precisely locate the steerable catheter sensor tip and sensor orientation in pigs' cardiac chambers.

Background: The WISEWOMAN program focuses on reducing cardiovascular disease (CVD) risk factors by providing screening and lifestyle interventions for many low-income and uninsured women. To provide the most effective interventions possible, it is important to understand the characteristics of WISEWOMAN participants and their communities.

Methods: We used baseline data collected for WISEWOMAN participants from five states (Connecticut, Michigan, Nebraska, North Carolina, and South Dakota) who had enrolled in WISEWOMAN between January 2001 and December 2002 in order to examine body mass index (BMI) and smoking behavior for evidence of spatial clustering.

Background: Compelling success stories, rich with details about real-life events and people, are a tool that health agencies can use to convey how their health promotion programs work, why they are successful, what lessons they have learned, and how others can launch similar programs. Success stories describe project accomplishments that are not easily captured by quantitative evaluation methods, such as surveys.

Methods: Although success stories have not been widely used in public health, the North Carolina Department of Health and Human Services developed a series of stories, the Community Change Chronicles, to highlight environmental and policy changes that promote cardiovascular health.

Background: Although most health departments recognize the need for programs to reduce the risk of cardiovascular disease (CVD) among older, low-income women, they face numerous barriers to successfully implementing such programs. This paper explores counselors' attitudes and beliefs about patients and perceived barriers to implementing the North Carolina Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) program.

Methods: Health departments were assigned to provide patients with either an enhanced intervention (EI) or a minimum intervention (MI).

Background: We used the baseline data collected for the Well-integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) participants to provide a snapshot of cardiovascular disease (CVD) risk on enrollment and to address racial/ethnic disparities in the following CVD risk factors: body mass index (BMI), systolic and diastolic blood pressure, high-density lipoprotein (HDL) and total cholesterol, diabetes and smoking prevalence, 10-year coronary heart disease (CHD) risk, and treatment and awareness of high cholesterol, hypertension, and diabetes.

Methods: We used linear regression analysis to (1) assess the presence of racial/ethnic disparities and test whether existing disparities can be explained by (2) differences in individual characteristics or by (3) differences in individual and community characteristics.

Results: Our results reveal a high degree of CVD risk among the WISEWOMAN participants and statistically significant racial/ethnic disparities in risk factors.
