Guide to assembling a successful K99/R00 application.

The National Institutes of Health's (NIH) K99/R00 Pathway to Independence Award offers promising postdoctoral researchers and clinician-scientists an opportunity to receive research support at both the mentored and the independent levels with the goal of facilitating a timely transition to a tenure-track faculty position. This transitional program has been generally successful, with most K99/R00 awardees successfully securing R01-equivalent funding by the end of the R00 period. However, often highly promising proposals fail because of poor grantsmanship. This overview provides guidance from the perspective of long-standing members of the National Heart, Lung, and Blood Institute's Mentored Transition to Independence study section for the purpose of helping mentors and trainees regarding how best to assemble competitive K99/R00 applications.

MOBILE Intervention Pilot Study in College Students With Elevated Blood Pressure.

BACKGROUND: Hypertension is typically recognized in middle-aged and older adults but often overlooked in younger populations. OBJECTIVE: We evaluated a mobile intervention for reducing blood pressure (BP) in college-age students for 28 days. METHODS: Students with elevated BP or undiagnosed hypertension were assigned to an intervention or control group. All subjects completed baseline questionnaires and attended an educational session. For 28 days, intervention subjects sent their BP and motivation levels to the research team and completed assigned BP-reducing tasks. After 28 days, all subjects completed an exit interview. RESULTS: We found a statistically significant decrease in BP in the intervention group only ( P = .001) but no statistical difference in sodium intake for either group. Mean hypertension knowledge increased in both groups but was only significant for the control group ( P = .001). CONCLUSIONS: The results provide preliminary data on BP reduction with greater impact on the intervention group.

(Pro)renin Receptor and Blood Pressure Regulation: A Focus on the Central Nervous System.

The renin-angiotensin system (RAS) is classically described as a hormonal system in which angiotensin II (Ang II) is one of the main active peptides. The action of circulating Ang II on its cognate Ang II type-1 receptor (AT1R) in circumventricular organs has important roles in regulating the autonomic nervous system, blood pressure (BP) and body fluid homeostasis, and has more recently been implicated in cardiovascular metabolism. The presence of a local or tissue RAS in various tissues, including the central nervous system (CNS), is well established. However, because the level of renin, the rate-limiting enzyme in the systemic RAS, is very low in the brain, how endogenous angiotensin peptides are generated in the CNS-the focus of this review-has been the subject of considerable debate. Notable in this context is the identification of the (pro)renin receptor (PRR) as a key component of the brain RAS in the production of Ang II in the CNS. In this review, we highlight cellular and anatomical locations of the PRR in the CNS. We also summarize studies using gain- and loss-of function approaches to elucidate the functional importance of brain PRR-mediated Ang II formation and brain RAS activation, as well as PRR-mediated Ang II-independent signaling pathways, in regulating BP. We further discuss recent developments in PRR involvement in cardiovascular and metabolic diseases and present perspectives for future directions.
