197 In one animal study

it was shown that triptans disrupted communication between peripheral and central trigeminovascular neurons.198 In a group of 28 migraine patients with allodynia treated 4 hours after onset, subcutaneous sumatriptan was ineffective in 14 patients. These patients were subsequently treated i.v. with the COX1/COX2 inhibitor ketorolac as were 14 other allodynic patients.199 A PF state was observed in 71% and 64%, respectively.199 In animal studies COX1/COX2 inhibitors, ketorolac, indomethacin, and naproxen, can exert inhibition of the central trigeminovascular this website neurons and can suppress central sensitization in rats.200 In contrast, subcutaneous sumatriptan was equally effective when given early (62% PF after 2 hours) or late (55% PF after 2 hours) during migraine attacks in one open study (n = 20).201 In an unpublished RCT (n = 90) both early and late (4 hours) treatment of migraine attacks PLX4032 cost with subcutaneous sumatriptan 6 mg resulted in headache relief in about 80% in both groups.201 In addition, subcutaneous naratriptan 10 mg in an RCT

resulted in 88% of patients (n = 34) being PF after 2 hours even if more that 50% were treated after 4 hours.202,203 These 2 studies indicate that parenteral triptans are equally effective when used early or late in the treatment of migraine attacks. Another way to circumvent the problem of allodynia is to treat early which makes common sense. In one prospective, placebo-controlled RCT with almotriptan 12.5 mg it was demonstrated that early (<1 hour) and mild headache treatment (53% PF) was superior

to treatment of moderate or severe headache (38% PF).204 Citations of Highlighted Papers.— There was comparable, and reasonable, agreement between ISI Web of Knowledge and Google Scholar (see Table 2). The 2 papers with most citations, are Leão’s paper (1129) on CSD10 and the Leiden Group’s paper (1215) on the gene for FHM1.19 In this review we tried to highlight the major clinical and scientific observations of migraine from 1910 to 2010. This was undertaken from the present perspective selleck screening library and therefore observations that may have seemed important in the past may have been omitted, although we believe we have touched upon the main areas that have occupied migraine investigators. After the discovery of ergotamine in the late 19th century, its isolation in the early 20th century led to rather primitive trials (from today’s perspective) as well as research on the pathogenesis of migraine. American research of therapeutics in the 1930s seemed more thorough than the early European endeavors.

“Nonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease, and is strongly associated with the metabolic syndrome. In the last decade, it has become apparent that the clinical burden of NAFLD is not restricted to liver-related morbidity or mortality, and the majority of deaths in NAFLD patients are related to cardiovascular disease (CVD) and cancer. These findings have fuelled concerns that NAFLD may be a new, and added risk factor for extrahepatic diseases such as CVD, chronic kidney disease (CKD), colorectal cancer, endocrinopathies (including type 2 diabetes mellitus [T2DM] and thyroid dysfunction), and osteoporosis. In this review we critically appraise key studies on NAFLD-associated extrahepatic disease. There was marked heterogeneity

between studies in study design (cross-sectional versus prospective; sample size; presence/absence of well-defined controls), population (ethnic diversity; community-based versus hospital-based cohorts), and method of NAFLD diagnosis (liver enzymes versus imaging versus biopsy). Taking HSP inhibitor this into account, the cumulative evidence to date suggests that individuals with NAFLD (specifically, nonalcoholic steatohepatitis) harbor an increased and independent risk of developing CVD, T2DM, CKD, and colorectal neoplasms. We propose future studies are necessary to better understand these risks, and suggest

an example of a screening strategy. (Hepatology 2014;59:1174–1197) “
“Senescence marker protein 30 (SMP30), an important aging marker molecule that is highly expressed in the liver, has been known to protect hepatocytes from apoptosis by the synthesis of vitamin C. To explore the function of SMP30 in liver fibrosis, the effect of SMP30 deficiency on liver fibrosis was investigated in SMP30 knockout (KO) mice. Moreover, the in vivo results were further confirmed by way of hepatic stellate cell (HSC) isolation. selleck chemicals We demonstrated that carbon tetrachloride (CCl4)-induced liver fibrosis and the nuclear translocation of p-Smad2/3, the immediate downstream of transforming growth factor beta (TGF-β), were significantly inhibited in the liver of SMP30 KO mice compared with wildtype (WT) mice. We also confirmed that both WT and SMP30 KO HSCs did not express SMP30. Finally, we further confirmed that up-regulation of peroxisome proliferator-activated receptor-gamma (PPAR-γ) caused by a lack of vitamin C was the pivotal factor in the mechanisms for attenuated liver fibrosis of SMP30 KO mice, and feeding with vitamin C restored CCl4-induced liver fibrosis in SMP30 KO mice. Conclusion: Vitamin C deficiency by SMP30 depletion attenuated liver fibrosis by way of up-regulated PPAR-γ expression in SMP30 KO mice.
