Longitudinal Changes in CT Body Composition in Patients Undergoing Surgery for Colorectal Cancer and Associations With Peri-Operative Clinicopathological Characteristics.

There is evidence for the direct association between body composition, the magnitude of the systemic inflammatory response, and outcomes in patients with colorectal cancer. Patients with a primary operable disease with and without follow-up CT scans were examined in this study. CT scans were used to define the presence and changes in subcutaneous fat, visceral fat, skeletal muscle mass, and skeletal muscle density (SMD).

Prevalence of high-risk drug-drug interactions in paediatric inpatients: a retrospective, single-centre cohort analysis.

Aims Of The Study: Drug-drug interaction (DDI) screening programmes aim to increase the safety of medication by issuing alerts based on the severity of DDIs, since an increased risk of adverse drug events has been reported for some DDIs (clinically relevant alerts). However, not all DDI alerts may be clinically relevant, depending on the clinical decision support system (CDSS) interaction tool used and the target population. There are few data about the frequency and relevance of DDIs in the paediatric population.

Persistent high-risk behavior and escalating HIV, syphilis and hepatitis B incidences among men who have sex with men living in Bangui, Central African Republic.

Introduction: HIV in sub-Saharan Africa remains a great concern in men who have sex with men (MSM). Intervention on MSM is a key strategy to control the burden of HIV among this population. Herein we assessed the effect of 2 years of HIV testing and counseling on risk-tacking and HIV and STI incidences among MSM living in Bangui in the Central African Republic.

The relationship between computed tomography-derived body composition, systemic inflammatory response, and survival in patients undergoing surgery for colorectal cancer.

Introduction: Colorectal cancer is the fourth leading cause of cancer mortality in developed countries. There is evidence supporting a disproportionate loss of skeletal muscle as an independent prognostic factor. The importance of the systemic inflammatory response as a unifying mechanism for specific loss of skeletal muscle mass in patients with cancer is increasingly recognized.

Optimization of process configuration and strain selection for microalgae-based biodiesel production.

A mathematical model was developed for the design of microalgae-based biodiesel production system by systematically integrating all the production stages and strain properties. Through the hypothetical case study, the model suggested the most economical system configuration for the selected microalgae strains from the available processes at each stage, thus resulting in the cheapest biodiesel production cost, S$2.66/kg, which is still higher than the current diesel price (S$1.

High-throughput viscosity measurement using capillary electrophoresis instrumentation and its application to protein formulation.

Viscosity characterization of protein formulations is of utmost importance for the development of subcutaneously administered formulations. However, viscosity determinations are time-consuming and require large sample volumes in the range of hundreds of microliters to a few milliliters, depending on the method used. In this article, an automated, high-throughput method is described to determine dynamic viscosity of Newtonian fluids using standard capillary electrophoresis (CE) equipment.

Polymersomes conjugated to 83-14 monoclonal antibodies: in vitro targeting of brain capillary endothelial cells.

The blood-brain barrier (BBB) remains an obstacle for many drugs to reach the brain. A strategy to cross the BBB is to modify nanocarrier systems with ligands that bind to endogenous receptors expressed at the BBB to induce receptor-mediated transport. The aim of the present study was to investigate the potential of polymersomes composed of the amphiphilic diblock copolymer poly(dimethylsiloxane)-block-poly(2-methyl-2-oxazoline), PDMS-b-PMOXA, for active targeting of brain capillary endothelial cells.

Pharmacological characterization of designer cathinones in vitro.

Background And Purpose: Designer β-keto amphetamines (e.g. cathinones, 'bath salts' and 'research chemicals') have become popular recreational drugs, but their pharmacology is poorly characterized.

On the significance of the anchoring group in the design of antenna materials based on phthalocyanine stopcocks and zeolite L.

The synthesis of stopcocks based on zinc phthalocyanine for selective adsorption at the channel entrances of zeolite L is reported. The introduction of either an inert SiMe₃ moiety, an imidazolium cation or a reactive isothiocyanate (NCS) group allows attachment to the channel entrances of zeolite L through van der Waals interactions, electrostatic interactions, or covalent binding, respectively. Stopcocks that rely on van-der-Waals-driven adsorption require careful selection of the solvent used for the deposition onto the zeolite surface to avoid a nonspecific distribution of the molecules.

Surprising properties of a furo-furanone.

The electronic absorption, fluorescence, and excitation spectra of furo[3,4-c]furanone (1) have been measured in different solvents at different concentrations. We observed a complex dependence of absorption and excitation spectra as a function of the concentration in CH(2)Cl(2) and THF due to aggregate formation. Interestingly, the fluorescence spectra were not affected.

Probing molecular order in zeolite L inclusion compounds using two-photon fluorescence polarimetric microscopy.

We investigate the local static molecular orientational behavior in zeolite L inclusion compounds by polarimetric two-photon fluorescence microscopy. This technique, based on the polarized read-out of the signal under a tunable incident polarization state, provides refined information on molecular disorder that is not achievable using traditional fluorescence anisotropy. Moreover, the polarimetric microscopy imaging scheme permits a spatial investigation of possible heterogeneities, with a submicrometric resolution.

Novel phthalocyanine-based stopcock for zeolite L.

We report the first phthalocyanine-based stopcock for selective adsorption to the channel entrances of zeolite L and realisation of a new electronic dipole moment coupling situation.

Context: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centers (FNCLCC), the 20 French cancer centers and specialists from French public university and general hospitals and private clinics. Its main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery.
