Atorvastatin reduces endotoxin-induced microvascular inflammation via NOSII.

In a lipopolysaccharide (LPS)-induced rat model of sepsis (endotoxaemia), we previously demonstrated that pravastatin reduced microvascular inflammation via increased endothelial nitric oxide synthase III (NOSIII). This study aimed to determine whether atorvastatin, the most commonly used statin for lowering cholesterol, exerted beneficial pleiotropic effects via a similar mechanism. The mesenteric microcirculation of anaesthetised male Wistar rats (308 ± 63 g, n = 54) was prepared for fluorescent intravital microscopy.

ROCK induced inflammation of the microcirculation during endotoxemia mediated by nitric oxide synthase.

Sepsis may be modeled using lipopolysaccharide (LPS), which alters levels of nitric oxide (NO), synthesized via endothelial and inducible nitric oxide synthase (eNOS and iNOS). This study aimed to determine whether the Rho kinase (ROCK) inhibitor fasudil protected against LPS-induced (endotoxemia) macromolecular leak and leukocyte adhesion via NOS pathways. Male Wistar rats (283±8g, n=36) were anaesthetized with thiopental and the mesentery prepared for fluorescent intravital microscopy (IVM).

Improved patient satisfaction and pain evolution with almotriptan in migraine: a primary care study.

Background/objective: The START study was a large general practice observational study involving 400 patients with migraine. Given the large sample size, a sub-analysis was planned to ascertain whether any patient characteristics/behaviors might help predict/explain the responses observed in this study, which demonstrated that almotriptan administered early when pain was mild significantly improved pain-related outcomes compared with non-early/non-mild treatment.

Methods: This pre-planned sub-analysis assessed the impact of predictors of patient satisfaction, medication history, delayed drug intake, etc.

Almotriptan: a review of 10 years' clinical experience.

Almotriptan, a serotonin 5-HT 1B/1D agonist, was developed for the acute treatment of migraine with or without aura and has been available for 10 years. This article evaluates the wealth of experience that has been obtained with almotriptan, including large randomized clinical trials (RCTs) and post-marketing studies that more closely reflect everyday clinical practice. Initial RCTs required patients to take almotriptan when migraine pain was of moderate or severe intensity, and found that 12.

Over-expression of δC-DCLK-short in mouse brain results in a more anxious behavioral phenotype.

Products of the Doublecortin-Like Kinase (DCLK) gene are associated with cortical migration and hippocampal maturation during embryogenesis. However, the functions of those DCLK gene transcripts that encode kinases and are expressed during adulthood are incompletely understood. To elucidate potential functions of these DCLK gene splice variants we have generated and analyzed transgenic mice with neuronal over-expression of a truncated, constitutively active form of DCLK-short, designated δC-DCLK-short.

Macromolecular leak from extrasplenic lymphatics during endotoxemia.

Background: The spleen has an important physiological role in maintaining blood volume; this study aimed to determine whether during pathophysiological circumstances, namely endotoxemia, the extrasplenic pathway is dysfunctional. We hypothesize that increased 'leakiness' of lymphatics in response to lipopolysaccharide (LPS) provides a route for loss of protein-rich fluid into third spaces and prevents the spleen from maintaining blood volume homeostasis.

Methods And Results: Male Wistar rats (200-280 g, n = 24) were anesthetized with thiopental (40-90 mg x kg(-1) x hr(-1), i.
