Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo

2021

Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…

Relationship between eating styles and temperament in an Anorexia Nervosa, Healtlhy Control, and Morbid Obesity female sample.

2014

Contains fulltext : 127209.pdf (Publisher’s version ) (Closed access) Objectives: Eating styles have been studied in both Obesity (OB) and Eating Disorders (ED), but they have not been examined in these two weight conditions together. The present study explores differences in eating styles in an Anorexia Nervosa (AN) and OB sample, compared to Healthy Controls (HC), and it analyses their relationship with Body Mass Index (BMI) and personality traits. Method: The total sample consisted of 291 female participants (66 AN, 79 OB and 146 HC). Evaluation: Assessment measures included the Dutch Eating Behaviour Questionnaire-DEBQ- and the Temperament and Character Inventory-Revised-TCI-R-. Results…

Population-level risks of alcohol consumption by amount, geography, age, sex, and year: a systematic analysis for the Global Burden of Disease Study …

2022

Background: The health risks associated with moderate alcohol consumption continue to be debated. Small amounts of alcohol might lower the risk of some health outcomes but increase the risk of others, suggesting that the overall risk depends, in part, on background disease rates, which vary by region, age, sex, and year. Methods: For this analysis, we constructed burden-weighted dose-response relative risk curves across 22 health outcomes to estimate the theoretical minimum risk exposure level (TMREL) and non-drinker equivalence (NDE), the consumption level at which the health risk is equivalent to that of a non-drinker, using disease rates from the Global Burden of Diseases, Injuries, and …

Clearance of Ascorbic Acid in Plasma in Patients Before Major Maxillofacial Surgery Compared With That in Volunteers

2002

Reduced concentration of ascorbic acid (AA) in plasma is often observed in tumor patients. Besides malnutrition, an increased AA consumption in tumor patients is discussed as a main reason for reduced AA concentration in plasma. A reduced AA concentration caused by malnutrition would not influence the total clearance (Cltot) of AA in plasma; however, a change in AA consumption would alter the Cltot. To investigate this further, a study was carried out on 20 patients hospitalized for major maxillofacial surgery and 20 volunteers. The Cltot of AA in plasma after bolus injection of AA (4 mg/kg body wt) in tumor patients was compared with that in volunteers. AA concentration in plasma (P0.05) w…

Effect of sensory exposure on liking for fat- or sugar-reduced biscuits

2015

This study investigates the effect of exposure to fat- or sugar-reduced biscuits on liking for these products. Two sets of biscuits were manufactured, each including a standard variant and 4 variants differing by the level of reduction of either fat or sugar content, to 33% of fat content or 28% of sugar content. Biscuit consumers were recruited to eat either the fat (n ¼ 113) or the sugar-reduced set of biscuits (n ¼ 106). They participated in 5 testing sessions, once a week, in laboratory conditions. During each session, they rated their liking of the 5 variants. At the end of each of the 4 first sessions, consumers were given 16 biscuits for their home consumption during the week. Partic…

Reduced intensity conditioning HLA identical sibling donor allogeneic stem cell transplantation for patients with follicular lymphoma: long-term foll…

2010

Background Allogeneic hematopoietic stem cell transplantation is an effective treatment for patients with poor risk lymphoma, at least in part because of the graft-versus-lymphoma effect. Over the past decade, reduced intensity conditioning regimens have been shown to offer results similar to those of conventional high-dose conditioning regimens but with lower toxicity early after transplantation, especially in patients with chemosensitive disease at transplant. Design and Methods The aim of this study was to analyze the long-term outcome of patients with follicular lymphoma who received an HLA identical sibling allogeneic stem cell transplant with a reduced intensity conditioning regimen w…

Effect of Stiffness on the Micellization Behavior of Model H4T4 Surfactant Chains

2006

The micellization behavior of a series of model surfactants, all with four head and tail groups (H4T4) but with different degrees of chain stiffness, was studied using grand canonical Monte Carlo simulations on a cubic lattice. The critical micelle concentration, micellar size, and thermodynamics of micellization were examined. In all cases investigated, the critical micelle concentration was found to increase with increasing temperature as observed for nonionic surfactants in apolar or slightly polar solvents. At a fixed reduced temperature and increasing chain stiffness, in agreement with previous observations, it was found that the critical micelle concentration decreased and the average…

Long-range interactions and the sign of natural amplitudes in two-electron systems

2013

In singlet two-electron systems the natural occupation numbers of the one-particle reduced density matrix are given as squares of the natural amplitudes which are defined as the expansion coefficients of the two-electron wave function in a natural orbital basis. In this work we relate the sign of the natural amplitudes to the nature of the two-body interaction. We show that long-range Coulomb-type interactions are responsible for the appearance of positive amplitudes and give both analytical and numerical examples that illustrate how the long-distance structure of the wave function affects these amplitudes. We further demonstrate that the amplitudes show an avoided crossing behavior as func…
