TL;DR: The authors discusses shortcomings of the usual blood pressure hypothesis, provides background to accompanying reports on the importance of blood pressure variability in prediction of risk of vascular events and in accounting for benefits of antihypertensive drugs, and draws attention to clinical implications and directions for future research.

TL;DR: The background underpinning the clinical use of ultrashort echo-time (UTE) pulse sequences for imaging tissues or tissue components with short T2s is reviewed and clinical features of the imaging of cortical bone, tendons, ligaments, menisci, and periosteum as well as brain, liver, and spine are illustrated.
Abstract: The background underpinning the clinical use of ultrashort echo-time (UTE) pulse sequences for imaging tissues or tissue components with short T2s is reviewed. Tissues properties are discussed, and tissues are divided into those with a majority of short T2 relaxation components and those with a minority. Features of the basic physics relevant to UTE imaging are described including the fact that when the radiofrequency pulse duration is of the order T2, rotation of tissue magnetization into the transverse plane is incomplete. Consequences of the broad line-width of short T2 components are also discussed including their partial saturation by off-resonance fat suppression pulses as well as multislice and multiecho imaging. The need for rapid data acquisition of the order T2 is explained. The basic UTE pulse sequence with its half excitation pulse and radial imaging from the center of k-space is described together with options that suppress fat and/or long T2 components. Image interpretation is discussed. Clinical features of the imaging of cortical bone, tendons, ligaments, menisci, and periosteum as well as brain, liver, and spine are illustrated. Short T2 components in all of these tissues may show high signals. Possible future developments are outlined as are technical limitations.

TL;DR: The proto-oncogene bcl-2 is abnormally expressed in some lung carcinomas, and its expression may have prognostic importance.
Abstract: Background The proto-oncogene bcl-2 encodes a protein that inhibits programmed cell death (apoptosis). The protein is expressed in basal cells in normal human epithelium, but no data are available on the frequency or clinical importance of its expression in carcinoma. We studied bcl-2 expression in patients with non-small-cell lung carcinoma and correlated this phenomenon with survival. Methods Immunochemical analysis with a monoclonal antibody specific for bcl-2 was used to detect the protein in tumor samples from 122 patients undergoing surgery for squamous-cell carcinoma (80 patients) or adenocarcinoma (42 patients). The possibility that bcl-2 expression correlated with survival was investigated with use of the log-rank test, hazard ratios, and their confidence intervals. Results We detected bcl-2 protein in 25 percent of squamous-cell carcinomas (20 of 80) and 12 percent of adenocarcinomas (5 of 42). In adjacent normal respiratory epithelium, bcl-2 was expressed only in basal cells. Survival at five y...

TL;DR: Functional studies in a mutant cell line expressing neither HIF-1alpha nor EPAS-1 confirmed that both proteins interact with hypoxically responsive targets, but suggest target specificity with greater EPas-1 transactivation of the VEGF promoter than the LDH-A promoter.
