W-SBA-15 as an Effective Catalyst for the Epoxidation of 1,5,9-Cyclododecatriene.

The results of a study on the epoxidation of 1,5,9-cyclododecatriene (CDT) on a W-SBA-15 catalyst using the batch and half-periodic methods are presented. During this study, the activity of the W-SBA-15 catalyst was compared to that of the Ti-SBA-15 catalyst, and the W-SBA-15 catalyst was found to be about 20 times more active than the Ti-SBA-15 catalyst. The highest CDT conversion so far, amounting to 86 mol%, was obtained after carrying out the 4 h epoxidation process.

Expanding Who I Am: Validating the Self-Expansion Preference Scale.

People's self-concepts are subject to change through various processes, one of which is self-expansion. Self-expansion is a motivation to increase one's self-concept through engaging in novel, exciting, and interesting activities or by taking on one's partner's qualities. Despite the plethora of research on self-expansion, there has not been much work on whether people vary in their desire to expand.

Princesses, Princes, and Superheroes: Children's Gender Cognitions and Fictional Characters.

The goal of the present study was to identify whether children recognize the gender stereotypes prevalent within the increasingly popular princess, prince, and superhero characters. Interviews with 126 children from the northeast region of the Unites States (3-11 years old) indicated that children recognized the gender-typed personality traits of princesses, princes, and superheroes, with older children holding more gender-typed cognitions about the characters. Children's own-schemas (i.

Systemic lipopolysaccharide administration impairs retrieval of context-object discrimination, but not spatial, memory: Evidence for selective disruption of specific hippocampus-dependent memory functions during acute neuroinflammation.

Neuroinflammation is implicated in impairments in neuronal function and cognition that arise with aging, trauma, and/or disease. Therefore, understanding the underlying basis of the effect of immune system activation on neural function could lead to therapies for treating cognitive decline. Although neuroinflammation is widely thought to preferentially impair hippocampus-dependent memory, data on the effects of cytokines on cognition are mixed.

Under pressure: the effects of stress on positive and negative relationship behaviors.

This study investigates the effects of acute stress on positive and negative relationship behaviors, specifically assurances and attention to alternatives. A sample of 129 college students were randomly assigned to either a high or low stress condition, then were led to believe they had the opportunity to interact with attractive potential relationship partners and list compliments about their current partner. Results indicated that those in the high stress condition gave their partner fewer assurances and paid more attention to alternatives.

AAVshRNA-mediated suppression of PTEN in adult rats in combination with salmon fibrin administration enables regenerative growth of corticospinal axons and enhances recovery of voluntary motor function after cervical spinal cord injury.

Conditional genetic deletion of phosphatase and tensin homolog (PTEN) in the sensorimotor cortex of neonatal mice enables regeneration of corticospinal tract (CST) axons after spinal cord injury (SCI). The present study addresses three questions: (1) whether PTEN knockdown in adult rats by nongenetic techniques enables CST regeneration, (2) whether interventions to enable CST regeneration enhance recovery of voluntary motor function, and (3) whether delivery of salmon fibrin into the injury site further enhances CST regeneration and motor recovery. Adult rats were trained in a staircase-reaching task and then received either intracortical injections of AAVshPTEN to delete PTEN or a control vector expressing shRNA for luciferase (AAVshLuc).

Selective localization of arc mRNA in dendrites involves activity- and translation-dependent mRNA degradation.

Arc is an immediate early gene that is unique among neuronal mRNAs because its transcripts are transported into dendrites and accumulate near activated synapses, presumably to be translated locally. These qualities pose Arc as playing an important, yet not fully understood, role in the activity-dependent modifications of synapses that are thought to underlie memory storage. Here we show in vivo in rats that newly synthesized Arc mRNA accumulates at activated synapses and that synaptic activity simultaneously triggers mRNA decay that eliminates Arc mRNA from inactive dendritic domains.

The analgesic and anti-inflammatory effect of new oleanolic acid acyloxyimino derivative.

The new derivative of well-known triterpene, oleanolic acid: methyl 3-octanoyloxyiminoolean-12-en-28-oate 5, was synthesized by the action of caprylic acid on methyl oleanolate 3-oxime in the presence of dicyclohexylcarbodiimide in dioxane. The molecular structure of the obtained product 5 was confirmed by spectral methods. The acute toxicity, locomotor activity, and the dose-dependent analgesic activity were studied.

Hungry for love: the influence of self-regulation on infidelity.

The current research examines the effect of self-regulation on the likelihood of committing infidelity. Thirty-two college students in exclusive romantic relationships interacted through a private chat room with an opposite-sex confederate. Prior to this interaction, a food-restriction task depleted half the participants of self-control.

Reactions of N(3) -substituted amidrazones with cis-1,2-cyclohexanedicarboxylic anhydride and biological activities of the products.

A series of novel compounds were synthesized in reactions of N(3) -substituted amidrazones with cis-1,2-cyclohexanedicarboxylic anhydride: linear, isoindole, and triazole derivatives. All new structures were confirmed by H(1) NMR and IR spectrometry as well as elemental analysis. Potential biological effects of new compounds were predicted with the Prediction of Activity Spectra for Substances (PASS) program.

A multicenter, randomized, phase 2 clinical trial to evaluate the efficacy and safety of combination docetaxel and carboplatin and sequential therapy with docetaxel then carboplatin in patients with recurrent platinum-sensitive ovarian cancer.

Background: The aim of this randomized clinical trial was to evaluate the efficacy and safety of combination (cDC) and sequential (sDC) weekly docetaxel and carboplatin in women with recurrent platinum-sensitive epithelial ovarian cancer (EOC).

Methods: Participants were randomized to either weekly docetaxel 30 mg/m(2) on days 1 and 8 and carboplatin area under the curve (AUC) = 6 on day 1, every 3 weeks or docetaxel 30 mg/m(2) on days 1 and 8, every 3 weeks for 6 cycles followed by carboplatin AUC = 6 on day 1, every 3 weeks for 6 cycles or until disease progression. The primary endpoint was measurable progression-free survival (PFS).

Health-related quality of life outcomes of docetaxel/carboplatin combination therapy vs. sequential therapy with docetaxel then carboplatin in patients with relapsed, platinum-sensitive ovarian cancer: results from a randomized clinical trial.

Objectives: A phase II clinical trial compared docetaxel in combination with carboplatin to sequential single agent docetaxel followed by carboplatin for treatment of recurrent platinum-sensitive ovarian, peritoneal, or tubal cancer. This manuscript reports prospectively collected health-related quality of life (HRQL).

Methods: Participants were randomized to either weekly docetaxel 30 mg/m(2)/days 1 and 8 and carboplatin AUC 6/day 1 every 3 weeks (cDC) or docetaxel 30 mg/m(2)/days 1 and 8, repeated every 3 weeks for 6 cycles followed by carboplatin AUC 6/day 1 every 3 weeks for 6 cycles or until disease progression (sDC).

Assessment of the role of MAP kinase in mediating activity-dependent transcriptional activation of the immediate early gene Arc/Arg3.1 in the dentate gyrus in vivo.

Different physiological and behavioral events activate transcription of Arc/Arg3.1 in neurons in vivo, but the signal transduction pathways that mediate induction in particular situations remain to be defined. Here, we explore the relationships between induction of Arc/Arg3.

Are prediction models for Lynch syndrome valid for probands with endometrial cancer?

Currently, three prediction models are used to predict a patient's risk of having Lynch syndrome (LS). These models have been validated in probands with colorectal cancer (CRC), but not in probands presenting with endometrial cancer (EMC). Thus, the aim was to determine the performance of these prediction models in women with LS presenting with EMC.

An investigation of the cortical control of forepaw gripping after cervical hemisection injuries in rats.

Previous studies in mice have demonstrated that forepaw gripping ability, as measured by a grip strength meter (GSM), is dependent on the contralateral sensorimotor cortex, but this dependency changes after hemisection injury at cervical level 4 (C4). Initially, the mouse fails to grip with the forepaw ipsilateral to the hemisection but gripping recovers. Additionally, a mouse's gripping by the contralateral paw becomes independent of the sensorimotor cortex, indicating a reorganization of cortical control of gripping function (Blanco, J.

Phase II trial of cetuximab and carboplatin in relapsed platinum-sensitive ovarian cancer and evaluation of epidermal growth factor receptor expression: a Gynecologic Oncology Group study.

Purpose: This phase II trial assessed the activity and tolerability of cetuximab (C225, Erbitux) in combination with carboplatin in patients with relapsed platinum-sensitive ovarian or primary peritoneal carcinoma.

Patients And Methods: Patients were to receive combination therapy with cetuximab (initial dose of 400 mg/m2 intravenously on cycle 1, day 1, followed by weekly infusions of 250 mg/m2) and carboplatin (AUC of 6 on day 1 and every 3 weeks). The primary objectives of this trial were to estimate the anti-tumor activity and adverse events of this combination therapy.

Networks of neurons, networks of genes: an integrated view of memory consolidation.

Investigations into the mechanisms of memory formation have abided by the central tenet of the consolidation theory-that memory formation occurs in stages which differ in their requirement for protein synthesis. The current most widely accepted hypothesis posits that new memories are encoded as neural activity-induced changes in synaptic efficacy, and stabilization of these changes requires de novo protein synthesis. However, the basic assumptions of this view have been challenged by concerns regarding the specificity of the effects of the protein synthesis inhibitors used to support the claim.

Something's missing: need fulfillment and self-expansion as predictors of susceptibility to infidelity.

The present authors investigated whether an individual's motivations that are related to need fulfillment and self-expansion within a romantic relationship can predict self-reported susceptibility to infidelity. A sample of 109 college students (50 men, 59 women) who were in dating relationships completed questionnaires that assessed 5 types of variables of need fulfillment (i.e.

Screening for Lynch syndrome (hereditary nonpolyposis colorectal cancer) among endometrial cancer patients.

Endometrial cancer is the most common cancer in women with Lynch syndrome. The identification of individuals with Lynch syndrome is desirable because they can benefit from increased cancer surveillance. The purpose of this study was to determine the feasibility and desirability of molecular screening for Lynch syndrome in all endometrial cancer patients.

Thermal decomposition of methylene-4,4'-di(ethylphenyl-carbamate) to methylene-4,4'-di(phenylisocyanate).

During thermal decomposition of methylene-4,4'-di(ethylphenylcarbamate) (MDU), methylene-4,4'-di(phenylisocyanate) (MDI) appears to be the main product, provided that the ethanol formed in the reaction is carried away. Polycarbodiimides are the main by-products along with small amounts of 4,4'-di(aminophenyl)methane and its derivatives. Under the reaction conditions used in these studies, the latter compound together with its derivatives, reacts both with MDI and MDU.
