Precision measurement of charged pion and kaon differential cross sections in e+ e- annihilation at sqrt[s]=10.52 GeV.

Measurements of inclusive differential cross sections for charged pion and kaon production in e+ e- annihilation have been carried out at a center-of-mass energy of sqrt[s]=10.52  GeV. The measurements were performed with the Belle detector at the KEKB e+ e- collider using a data sample containing 113×10(6) e+ e- → qq events, where q={u,d,s,c}.

Evidence of a new narrow resonance decaying to χ(c1)γ in B→χ(c1)γK.

We report measurements of B→χ(c1)γK and χ(c2)γK decays using 772×10(6) BB[over ¯] events collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. Evidence of a new resonance in the χ(c1)γ final state is found with a statistical significance of 3.8σ.

Informal Trade of Psychoactive Herbal Products in the City of Diadema, SP, Brazil: Quality and Potential Risks.

The present study aimed to assess the quality and risks involved in the consumption of psychoactive herbal products (PHs) that are available through informal commerce in the city of Diadema, SP, Brazil. Methods of ethnography were used to conduct the fieldwork during which four dealers were selected to record the collection, handling, packaging, types of PHs marketed, and their therapeutic purposes. In addition, lots of the PHs selected were purchased from the dealers and analyzed using microbiology and pharmacognosy techniques.

Search for an H-dibaryon with a mass near 2mΛ in Υ(1S) and Υ(2S) decays.

We report the results of a high-statistics search for H dibaryon production in inclusive Υ(1S) and Υ(2S) decays. No indication of an H dibaryon with a mass near the M(H)=2m(Λ) threshold is seen in either the H→Λpπ(-) or ΛΛ decay channels and 90% confidence level branching-fraction upper limits are set that are between one and two orders of magnitude below the measured branching fractions for inclusive Υ(1S) and Υ(2S) decays to antideuterons. Since Υ(1S,2S) decays produce flavor-SU(3)-symmetric final states, these results put stringent constraints on H dibaryon properties.

Concurrent chemoradiotherapy with a novel fluoropyrimidine, S-1, and cisplatin for locally advanced esophageal cancer: long-term results of a phase II trial.

Possible adverse reactions to herbal products: a study with individuals who resort to popular medicine in the city of Diadema, SP, Brazil.

The present study aimed to investigate the occurrence of adverse reactions (ADRs) related to herbal products (HPs), which are purchased over-the-counter for self-treatment, reported by 100 users. Samples of the HPs related to those ADRs were purchased for their pharmacobotanical identification. The ADRs reported were evaluated based on specialized literature and were analyzed according to causality into probable (PR), possible (PO), unrelated (UR) or unclassifiable (UC); according to expectance into unexpected adverse reaction (UNEX) and expected adverse reaction (EX); seriousness into serious adverse event or reaction (S) and non-serious (NS); and severity into mild (MI), moderate (MO) and severe (SE).

Compound 1 was found to enhance the neurite outgrowth of NGF-mediated PC12 cells at concentrations ranging from 0.

Differences in spring-mass characteristics between one- and two-legged hopping.

Although many athletic activities and plyometric training methods involve both unilateral and bilateral movement, little is known about differences in the leg stiffness (K(leg)) experienced during one-legged hopping (OLH) and two-legged hopping (TLH) in place. The purpose of this study was to investigate the effect of hopping frequencies on differences in K(leg) during OLH and TLH. Using a spring-mass model and data collected from 17 participants during OLH and TLH at frequencies of 2.

Agranulocytosis after infectious mononucleosis.

We report the case of a 5-year-old boy with agranulocytosis after infectious mononucleosis (IM). Antibodies against anti-human neutrophil-specific antigens (HNA)-1 were detected in his serum. A literature review on agranulocytosis after IM and our case suggest that anti-HNA-1 antibodies play important roles in agranulocytosis associated with IM.

Effects of Hsp90 inhibitors, geldanamycin and its analog, on ceramide metabolism and cytotoxicity in PC12 cells.

The inhibitors of heat shock protein-90 (Hsp90), geldanamycin (GA) and 17-(allylamino)-17-desmethoxygeldanamycin, show various cellular effects including destabilization of Hsp90 clients and expression of other chaperones, etc. and modulate cytotoxicity depending on cell types and stimuli.

Conjugated linoleic acids inhibit hypoxia inducible factor-1α stabilization under hypoxic condition in human hepatocellular carcinoma cells.

The anti-cancer effects of various fatty acids are drawing a lot of attention. To determine whether different fatty acids affect the hypoxic response of liver cancer cells, we examined the effects of various fatty acids on the stabilization of the hypoxia-inducible factor (HIF)-1α protein in the HepG2 human hepatocellular carcinoma (HCC) cell line under condition containing 1% O(2). Of the fatty acids examined, only 9cis, 11trans (c9, t11)-conjugated linoleic acid (CLA) and 10trans, 12cis (t10, c12)-CLA inhibited hypoxia-induced HIF-1α stabilization.

Identifying research needs for improving health care.

Insights from systematic reviews can help new studies better meet the priorities and needs of patients and communities. However, systematic reviews unfortunately have not yet achieved this position to direct and guide new research studies. The Agency for Healthcare Research and Quality's Evidence-based Practice Center Program uses systematic reviews to identify gaps in current evidence and has developed a systematic process of prioritizing these gaps with stakeholder input into clearly defined "future research needs.

PP121. Expression of PlGF, sFlt, MTF-1, HO-1 and HIF-1 alpha mRNAs in preeclampsia placenta and effect of preeclampsia sera on their expression of choriocarcinoma cells.

Introduction: Placenta growth factor (PlGF) is a growth factor originated from placenta. The sFlt-1 is soluble receptor for PlGF and suppresses PlGF function. It has been reported that in preeclampsia, serum level of PlGF decreased and sFlt-1 level increased and that preeclampsia placenta is in hypoxic condition.

Synthesis and the intestinal glucosidase inhibitory activity of 2-aminoresorcinol derivatives toward an investigation of its binding site.

2-Aminoresorcinol is a potent and selective intestinal glucosidase inhibitor. Unlike the majority of glucosidase inhibitors, it shows an uncompetitive mode of inhibition. In this study, we tested the intestinal glucosidase inhibitory activity of various 2-aminoresorcinol derivatives.

Arabidopsis RPT2a, 19S proteasome subunit, regulates gene silencing via DNA methylation.

The ubiquitin/proteasome pathway plays a crucial role in many biological processes. Here we report a novel role for the Arabidopsis 19S proteasome subunit RPT2a in regulating gene activity at the transcriptional level via DNA methylation. Knockout mutation of the RPT2a gene did not alter global protein levels; however, the transcriptional activities of reporter transgenes were severely reduced compared to those in the wild type.

Improvement by sodium dl-α-tocopheryl-6-O-phosphate treatment of moisture-retaining ability in stratum corneum through increased ceramide levels.

Sodium dl-α-tocopheryl-6-O-phosphate (1), a water-soluble derivative of vitamin E (dl-α-tocopherol, 2), exhibits protective effects against various type of skin damage. As reported herein, we found that topical application of 1 improves hygroscopicity and water holding capacity in the stratum corneum of hairless mice in vivo by increasing the ceramide content. In normal human epidermal keratinocytes, treatment with 1 increases ceramide levels and enhances gene expression of serine palmitoyltransferase, which catalyzes the first step of ceramide synthesis in vitro.
