TL;DR: Insight into how these receptors are rapidly moved into and out of synaptic membranes has profound implications for the understanding of the mechanisms of long-term potentiation and long- term depression.
Abstract: Long-term potentiation and long-term depression are processes that have been widely studied to understand the molecular basis of information storage in the brain. Glutamate receptors are required for the induction and expression of these forms of plasticity, and GABA (γ-aminobutyric acid) receptors are involved in their modulation. Recent insights into how these receptors are rapidly moved into and out of synaptic membranes has profound implications for our understanding of the mechanisms of long-term potentiation and long-term depression.

TL;DR: Support is provided for a model suggesting that prolonged stressors result in GCR, which, in turn, interferes with appropriate regulation of inflammation, which may have broad implications for understanding the role of stress in health.
Abstract: We propose a model wherein chronic stress results in glucocorticoid receptor resistance (GCR) that, in turn, results in failure to down-regulate inflammatory response. Here we test the model in two viral-challenge studies. In study 1, we assessed stressful life events, GCR, and control variables including baseline antibody to the challenge virus, age, body mass index (BMI), season, race, sex, education, and virus type in 276 healthy adult volunteers. The volunteers were subsequently quarantined, exposed to one of two rhinoviruses, and followed for 5 d with nasal washes for viral isolation and assessment of signs/symptoms of a common cold. In study 2, we assessed the same control variables and GCR in 79 subjects who were subsequently exposed to a rhinovirus and monitored at baseline and for 5 d after viral challenge for the production of local (in nasal secretions) proinflammatory cytokines (IL-1β, TNF-α, and IL-6). Study 1: After covarying the control variables, those with recent exposure to a long-term threatening stressful experience demonstrated GCR; and those with GCR were at higher risk of subsequently developing a cold. Study 2: With the same controls used in study 1, greater GCR predicted the production of more local proinflammatory cytokines among infected subjects. These data provide support for a model suggesting that prolonged stressors result in GCR, which, in turn, interferes with appropriate regulation of inflammation. Because inflammation plays an important role in the onset and progression of a wide range of diseases, this model may have broad implications for understanding the role of stress in health.

TL;DR: The goal is to provide guidance relevant to the interpretation of formative measurement results through the examination of the following six issues: multicollinearity; the number of indicators specified for a formatively measured construct; the possible co-occurrence of negative and positive indicator weights; the absolute versus relative contributions made by a formative indicator; nomological network effects
Abstract: Within the Information Systems literature, there has been an emerging interest in the use of formative measurement in structural equation modeling (SEM). This interest is exemplified by descriptions of the nature of formative measurement (e.g., Chin 1998a), and more recently the proper specification of formatively measured constructs (Petter et al. 2007) as well as application of such constructs (e.g., Barki et al. 2007). Formative measurement is a useful alternative to reflective measurement. However, there has been little guidance on interpreting the results when formative measures are employed. Our goal is to provide guidance relevant to the interpretation of formative measurement results through the examination of the following six issues: multicollinearity; the number of indicators specified for a formatively measured construct; the possible co-occurrence of negative and positive indicator weights; the absolute versus relative contributions made by a formative indicator; nomological network effects; and the possible effects of using partial least squares (PLS) versus covariance-based SEM techniques. We provide prescriptions for researchers to consider when interpreting the results of formative measures as well as an example to illustrate these prescriptions.

TL;DR: Indomethacin appeared to protect mild to moderately impaired Alzheimer's disease patients from the degree of cognitive decline exhibited by a well-matched, placebo-treated group.
Abstract: In a 6-month, double-blind, placebo-controlled study, 100 to 150 mg/d indomethacin appeared to protect mild to moderately impaired Alzheimer's disease patients from the degree of cognitive decline exhibited by a well-matched, placebo-treated group. Over a battery of cognitive tests, indomethacin patients improved 1.3% (+/- 1.8%), whereas placebo patients declined 8.4% (+/- 2.3%)--a significant difference (p < 0.003). Caveats include adverse reactions to indomethacin and the limited scale of the trial.

TL;DR: This review considers optimal management of sepsis from the point of early, goal-directed therapy, lung-protective ventilation, antibiotics, and additional therapies, such as activated protein C, as well as the use of corticosteroids, vasopressin, and intensive insulin.
Abstract: A better understanding of the inflammatory, procoagulant, and immunosuppressive aspects of sepsis has contributed to rational therapeutic plans. This review considers optimal management of sepsis from the point of early, goal-directed therapy, lung-protective ventilation, antibiotics, and additional therapies, such as activated protein C, as well as the use of corticosteroids, vasopressin, and intensive insulin.
