ODELAY: A Large-scale Method for Multi-parameter Quantification of Yeast Growth

2017

Growth phenotypes of microorganisms are a strong indicator of their underlying genetic fitness and can be segregated into 3 growth regimes: lag-phase, log-phase, and stationary-phase. Each growth phase can reveal different aspects of fitness that are related to various environmental and genetic conditions. High-resolution and quantitative measurements of all 3 phases of growth are generally difficult to obtain. Here we present a detailed method to characterize all 3 growth phases on solid media using an assay called One-cell Doubling Evaluation of Living Arrays of Yeast (ODELAY). ODELAY quantifies growth phenotypes of individual cells growing into colonies on solid media using time-lapse mi…

The B-cell receptor in control of tumor B-cell fitness: Biology and clinical relevance

2019

Surface expression of a functional B cell antigen receptor (BCR) is essential for the survival and proliferation of mature B cells. Most types of B-cell lymphoproliferative disorders retain surface BCR expression, including B-cell non-Hodgkin lymphomas (B-NHL) and chronic lymphocytic leukemia (CLL). Targeting BCR effectors in B-NHL cell lines in vitro has indicated that this signaling axis is crucial for malignant B cell growth. This has led to the development of inhibitors of BCR signaling, which are currently used for the treatment of CLL and several B-NHL subtypes. Recent studies based on conditional BCR inactivation in a MYC-driven mouse B-cell lymphoma model have revisited the role of …

Assessment of Muscular Fitness as a Predictor of Flight Duty Limitation.

2018

Introduction The high acceleration (Gz) exposure among military pilots flying fighter aircraft has been associated with an increased risk for cervical and lumbar disorders. It has been suggested that an adequate level of physical performance could reduce the risk of experiencing these disorders. The Finnish Air Force has for several years used aerobic (bicycle ergometer) and muscular fitness tests (battery of five tests) in the selection process of military pilot candidates in order to evaluate their physical fitness level. The aim of the study was to determine if these selection phase tests and anthropometry measures can predispose those individuals who might be at risk of developing sever…

Effects of High-Impact Training on Bone and Articular Cartilage: 12-Month Randomized Controlled Quantitative MRI Study

2013

Osteoarthritis and osteoporosis often coexist in postmenopausal women. The simultaneous effect of bone-favorable high-impact training on these diseases is not well understood and is a topic of controversy. We evaluated the effects of high-impact exercise on bone mineral content (BMC) and the estimated biochemical composition of knee cartilage in postmenopausal women with mild knee osteoarthritis. Eighty women aged 50 to 66 years with mild knee osteoarthritis were randomly assigned to undergo supervised progressive exercise three times a week for 12 months (n = 40) or to a nonintervention control group (n = 40). BMC of the femoral neck, trochanter, and lumbar spine was measured by dual-energ…

Background: An adequate level of muscular fitness is related to occupational performance in military personnel, including pilots flying high performance aircraft. The aim of this study was to describe the baseline level and the change in muscular fitness between the first and the second years of the Air Force Academy among fighter pilot cadets. Methods: The muscular strength and endurance test results of 182 male fighter pilot cadets were analyzed during their first year in the Air Force Academy and one year after. Maximal isometric strength tests included trunk flexion, trunk extension and bilateral leg extension tests, whereas muscle endurance was measured with modified a sit-up test and …

Role of biological control agents and physical treatments in maintaining the quality of fresh and minimally-processed fruit and vegetables

2019

International audience; Fruit and vegetables are an important part of human diets and provide multiple health benefits. However, due to the short shelf-life of fresh and minimally-processed fruit and vegetables, significant losses occur throughout the food distribution chain. Shelf-life extension requires preserving both the quality and safety of food products. The quality of fruit and vegetables, either fresh or fresh-cut, depends on many factors and can be determined by analytical or sensory evaluation methods. Among the various technologies used to maintain the quality and increase shelf-life of fresh and minimally-processed fruit and vegetables, biological control is a promising approac…

ACTIVIDAD FÍSICA Y DISCAPACIDAD: UN ESTUDIO CUALITATIVO CON MUJERES EN UN GIMNASIO ADAPTADO

2017

Este estudio explora cómo un grupo de mujeres con discapacidad (n=6) experimentan y perciben la práctica de actividad física en un gimnasio adaptado. Se utilizaron entrevistas semi-estructuradas como instrumento de recogida de datos cualitativos y se realizó un análisis temático inductivo. Los resultados se agruparon en torno a cuatro categorías temáticas emergentes: condición física y autonomía personal; papel paliativo del ejercicio; bienestar psicológico; relación social y apoyo. Destaca la experiencia satisfactoria de las participantes, en la que predomina una valoración positiva de procesos autorregulativos, la concepción social-relacional de la actividad física, y la relevancia del gi…

Trade, financial openness and dual banking economies: Evidence from GCC Region

2021

Abstract The recent wave of liberalization in Gulf Cooperation Council (GCC) countries has opened up a debate on the role of Islamic finance in the financial development of an economy. Using a comprehensive dataset of 43 Islamic and 49 conventional banks for the period 2007–2015, in this paper, we investigate the impact of trade and financial openness on financial development in the GCC region. We find that trade and financial openness have a positive effect on the profitability of both banking systems, while the interaction term of openness is negative for the profitability of Islamic banks. Moreover, trade and financial openness affect Islamic banks differently than conventional banks. No…

Research Summary We explore the qualitative differences in entries and exits over time. Using qualitative and quantitative data on 96 firms over 200 years, we study industry evolution from the perspective of individual decision‐making situations. Our historical and statistical analyses reveal the vital role of technology investments in determining firm outcomes, and the technological, institutional and governance dynamics that lead firms to invest or to abstain. Our main theoretical and methodological contribution concerns the importance of the multiplicity of firm‐level rationalities and decisions as fundamentals in theorizing on industry evolution. Managerial Summary What determines firm …
