Are you getting enough sleep … or too much? Sleep and stroke risk

This study found an association between stroke risk and longer sleep, longer midday napping, or poor sleep quality. But an association is not the same as causation. Rather than longer sleep duration causing strokes, there are other possible explanations for the findings. For example, people who sleep more at night or nap more during the day may have other risk factors for stroke, such as: A higher incidence of depression. Excessive sleeping or poor sleep quality may be symptoms of depression, and prior studies have noted higher stroke rates among depressed individuals. A more sedentary lifestyle. Those who are not active may sleep or nap more and also have more cardiovascular risk factors (such as smoking or hypertension) than those who exercise regularly. Past research has noted less favorable cholesterol levels and larger waist circumference among long sleepers and nappers. Sleep apnea. Longer sleep duration, more napping, and poor-quality sleep may be more common among people with sleep apnea, a condition linked to an increased risk of stroke. This new study did not ask subjects about sleep disorders such as sleep apnea. In addition, this study had weaknesses that could call its findings into question or limit its applicability. These include reliance on self-reported sleep habits and quality, and inclusion only of middle-aged and older Chinese adults without prior cancer or cardiovascular disease; the results might have been quite different if others were included in th...

Authors: Finley JR, Wixted JT, Roediger HL Abstract Recent research in the eyewitness identification literature has investigated whether simultaneous or sequential lineups yield better discriminability. In standard eyewitness identification experiments, subjects view a mock-crime video and then are tested only once, requiring large samples for adequate power. However, there is no reason why theories of simultaneous versus sequential lineup performance cannot be tested using more traditional recognition memory tasks. In two experiments, subjects studied DRM (Deese-Roediger-McDermott) word lists (e.g., bed, rest, tir...

In this study, we identified reliable miRNA clusters that can be used to subclassify HNSCC tumors as well as other squamous tumors of other anatomic locations. An institutional discovery cohort was generated using miRNA expression data from microarrays, and this was validated using publicly available next-generation microRNA sequencing data from TCGA. Further analysis of these subtypes revealed distinct biological and clinical features of HNSCC tumors based on the miRNA expression profiles, which provides new insights into the pathogenesis and treatment of HNSCC.

We show that NVP-CGM097 reduces tumour cell viability of in vitro and in vivo models of endocrine sensitive, endocrine resistant and palbociclib (CDK4/6 inhibitor) resistant p53 wildtype (p53wt) ER-positive breast cancer.

Contributors : Hiromu Suzuki ; Akira YorozuSeries Type : Expression profiling by arrayOrganism : Homo sapiensWe identified adipocyte enhancer binding protein 1 (AEBP1) as a novel tumor endothelial marker in colorectal cancer (CRC). To identify target genes of AEBP1 in endothelial cells, we knocked down AEBP1 in human umbilical vein endothelial cells (HUVECs). We found that genes associated with angiogenesis including aquaporin 1 (AQP1) and periostin (POSTN) are downregulated by AEBP1 knockdown in HUVECs, suggesting that AEBP1 may promote tumor angiogenesis through regulating these genes.
