Cyclosporine A (CsA) is a powerful immunosuppressive drug. However, nephrotoxicity resulting from its long-term usage has hampered its prolonged therapeutic usage. Schisandra chinensis extracts (SCE) have previously been used in traditional Chinese medicine and more recently coadministered with Western medicine for the treatment of CsA-induced side effects in the People's Republic of China. This study aimed to investigate the possible effects of SCE on the pharmacokinetics of CsA in rats and elucidate the potential mechanisms by which it hinders the development of CsA-induced nephrotoxicity. A liquid chromatography/tandem mass spectrometry method was developed and validated for determining the effect of SCE on the pharmacokinetics of CsA. Male Sprague Dawley rats, which were administered with CsA (25 mg/kg/d) alone or in combination with SCE (54 mg/kg/d and 108 mg/kg/d) for 28 days, were used to evaluate the nephroprotective effects of SCE. Our study showed that SCE increased the mean blood concentration of CsA. Furthermore, we found that the concomitant administration of SCE alongside CsA prevented the disruption of catalase activity and reduction in creatinine, urea, renal malondialdehyde, and glutathione peroxidase levels that would have otherwise occurred in the absence of SCE administration. SCE treatment markedly suppressed the expression of 4-hydroxynonenal, Bcl-2-associated X protein, cleaved caspase 3, and autophagy-related protein LC3 A/B. On the other hand, the expression of heme oxygenase-1, nuclear factor erythroid 2-related factor 2 (Nrf2), and P-glycoprotein was enhanced by the very same addition of SCE. SCE was also able to increase the systemic exposure of CsA in rats. The renoprotective effects of SCE were thought to be mediated by its antiapoptotic and antioxidant abilities, which caused the attenuation of CsA-induced autophagic cell death. All in all, these findings suggest the prospective use of SCE as an effective adjunct in a CsA-based immunosuppressive regimen.To clarify whether karyotype aberrations (KA) involving regions not covered by the standard fluorescence in situ hybridization (FISH) panel have independent prognostic relevance, we evaluated KA by conventional cytogenetics in a learning cohort (LC; n = 166) and a validation cohort (VC; n = 250) of untreated chronic lymphocytic leukemia (CLL) patients. In the VC, novel mitogens were used to improve metaphase generation and TP53, NOTCH1, and SF3B1 mutations were assessed. KA undetected by FISH were found in 35 and 35% of the cases in the LC and VC, respectively. In addition to FISH, KA allowed reclassification of 23 and 26% of cases in the LC and VC, respectively, into a higher cytogenetic risk group. By multivariate analysis, both in the LC and VC, KA other than isolated 13q deletion correlated with a shorter time to first treatment (TFT; P less then 0.001 and 0.003, respectively), while a complex karyotype predicted a worse overall survival (OS, P = 0.015 and 0.010, respectively). In the VC, where a comprehensive biologic assessment was performed, a shorter TFT was also predicted by stage (P less then 0.001), IGHV mutational status (P = 0.05), and del(17p)/TP53 mutations (P = 0.033) while stage (P = 0.023) and del(17p)/TP53 mutations (P = 0.024) independently predicted a shorter OS. FISH results did not independently impact on TFT and OS, in the LC and VC cohorts; this was also the case for NOTCH1 and SF3B1 mutations in the VC. We suggest that in CLL, conventional karyotyping with novel mitogens could be more effective than FISH for the detection of KA allowing for a more precise refinement of prognosis.I reflect on the evolution of meta-analysis in clinical research over 35 years since I first encountered the key ideas in the late 1970s.In this interview, we discuss my early uses of meta-analytic procedures, first to combine p-values and then to combine effect sizes as well. My interest in quantifying the magnitude and the statistical significance of the effect of interpersonal expectations probably grew out of the following (1) a long-held interest in the concept of replication and (2) a series of controversies over the very existence of any effect of interpersonal expectations held, for example, by psychological experimenters, classroom teachers, and leaders of various organizations.The 40-year history of meta-analysis is traced from the vantage point of one of its originators. Research syntheses leading to the first examples of meta-analysis are identified. Early meta-analyses of the literature on psychotherapy outcomes and school class size are recounted. The influence on the development of meta-analysis of several statisticians and psychologists is described. Finally, some directions for future development of research synthesis methods are suggested.We describe a new template-free method for the in situ formation of a monodispersed spherical mesoporous nanosilica-Torlon hollow-fiber composite. A thin layer of Torlon hollow fiber that comprises silica nanoparticles was created by the in situ extrusion of a tetraethyl orthosilicate/N-methyl-2-pyrrolidone solution in a sheath layer and a Torlon polymer dope in a core support layer. This new method can be integrated easily into current hollow-fiber composite fabrication processes. The hollow-fiber composites were then functionalized with 3-aminopropyltrimethoxy silane (APS) and evaluated for their CO2 -capture performance. The resulting APS-functionalized mesoporous silica nanoparticles/Torlon hollow fibers exhibited a high CO2 equilibrium capacity of 1.5 and 1.9 mmol g(-1) at 35 and 60 °C, respectively, which is significantly higher than values for fiber sorbents without nanoparticles reported previously.The association of polyphenol content of human diet with low-grade inflammation is not yet fully understood. It was the objective of this study to evaluate the association of flavonoid and lignan intake with frequently used and easily applicable in clinical practice low-grade inflammation biomarkers, in a novel holistic approach. A total of 5,948 women and 5,965 men (aged ≥ 35 years) were analysed from the Moli-sani cohort, randomly recruited from the general population. The EPIC-FFQ was used for dietary assessment. Flavonol, flavone, flavanone, flavanol, anthocyanin, isoflavone and lignan intakes were calculated using Eurofir eBASIS and the polyphenol antioxidant content (PAC)-score was constructed to assess the total content of diet in these nutrients. CRP levels, WBC and PLT count and granulocyte to lymphocyte ratio were conceived as low-grade inflammation biomarkers. INFLA-score was constructed summarizing synergistic effects of these biomarkers. The INFLA-score was negatively associated with PAC-score in different levels of adjustment, in both genders (for all β-coef less then 0, P less then 0.05). Crenolanib 10 units increase in PAC-score was associated with 5-8% decrease in the likelihood of higher low-grade inflammation status (i.e. higher quartile of INFLA-score) in men and women (odds ratio [ORs] 0.92 to 0.95, p less then 0.05). The total variation of INFLA-score that was explained by PAC-score was estimated to be 16.7% in women and 9.1% in men (%R²=16.7 and 9.1). In conclusion, polyphenol content of diet evaluated in a holistic approach was negatively associated with a score of low-grade inflammation biomarkers in a large population based study. For the first time low-grade inflammation was evaluated in a holistic way through INFLA-score and was associated with polyphenol content of diet.The New World marmoset monkey (Callithrix jacchus) has a relatively short gestational period compared with other primates but possesses a retina at a similar stage of maturation by birth. Previous studies have highlighted that the complex fovea of the marmoset undergoes a more rapid postnatal development in comparison with the Macaca monkey, reaching a mature stage earlier than these species. In this current study, we examined the prenatal proliferation profile of cells in the entire retina employing the thymidine analogs and also determined their phenotype by double-label immunocytochemistry using type-specific markers. Akin to other primate species, we demonstrate a centroperipheral gradient in the emergence of both neurons and Müller glia with cones, ganglion cells, and horizontal cells generated first in the fovea at fetal day (Fd)70-74 and with the last generated at the retinal edge at Fd115. Rods, bipolar cells, amacrine cells, displaced amacrine cells, and Müller glia were generated between Fd76 and Fd135 along the same gradient. Similar to foveal development, marmoset neuronal generation was rapid, only taking 51% of gestation whereas in Macaca this takes 81%.

Portopulmonary venous anastomoses (PPVA) are shunts between esophageal varices and pulmonary veins. Because PPVA can cause serious complications at the time of sclerotherapy for esophageal varices, it is essential to confirm the existence of any PPVA before treatment.

The study group comprised 101 patients in whom hemodynamics were evaluated on three-dimensional computed tomography (3D-CT) before either elective or prophylactic treatment of esophageal varices at Kitasato University East Hospital from October 2007 through August 2013. The presence or absence of PPVA, laboratory test results and 3D-CT findings were retrospectively examined in these patients.

Nine patients had PPVA, and 92 patients did not. The underlying diseases in the PPVA group were hepatitis C liver cirrhosis in three; non-B, non-C liver cirrhosis in three; non-alcoholic steatohepatitis in one; primary biliary cirrhosis in one; and autoimmune hepatitis in one. The distribution of underlying diseases did not differ between the PPVA group and the non-PPVA group. When the study variables were statistically compared between the groups, the incidence of large, coil-shaped esophageal varices (grade F3) differed significantly between the groups (P = 0.001). Multivariate analyses of factors related to PPVA revealed that only the grade F3 type of esophageal varices differed significantly between the groups (P = 0.005; hazard ratio, 5.21; 95% confidence interval, 3.1-16.4).

In patients with grade F3 esophageal varices, the treatment method should be selected on the basis of an accurate hemodynamic analysis using 3D-CT before therapy.

Several such conjugates were prepared utilizing different dipeptides in the linkage including Gly-Gly, l-Val-l-Cit, and all four stereoisomers of the Ala-Ala dipeptide. The properties of AaMCs could be altered by the choice of dipeptide in the linker. Each of the AaMCs, except the AaMC bearing a d-Ala-d-Ala peptide linker, displayed more bystander killing in vitro than maytansinoid ADCs that utilize disulfide linkers. In mouse models, the anti-CanAg AaMC bearing a d-Ala-l-Ala dipeptide in the linker was shown to be more efficacious against heterogeneous HT-29 xenografts than maytansinoid ADCs that utilize disulfide linkers, while both types of the conjugates displayed similar tolerabilities.
