Thin Films of Chiral Motors [PDF]

arXiv, 2011
Hydrodynamic flows in biological systems are often generated by active chiral processes near or on surfaces. Important examples are beating cilia, force generation in actomyosin networks, and motile bacteria interacting with surfaces. Here we develop a coarse grained description of active chiral films that captures generic features of flow and rotation

Pathways to Progressive Disability in Multiple Sclerosis: The Role of Glial Cells in Chronic CNS Inflammation

Glia, EarlyView.
ABSTRACT Multiple sclerosis (MS) is the most common non‐infectious inflammatory CNS disease, characterized by progressive neurodegeneration and focal demyelinated lesions. Traditionally considered an autoimmune disease, MS is driven by the immune system's attack on CNS myelin, resulting in cumulative disability.

Effective viscosity of a suspension of flagellar beating microswimmers: Three-dimensional modeling [PDF]

arXiv, 2014
Micro-organisms usually can swim in their liquid environment by flagellar or ciliary beating. In this numerical work, we analyze the influence of flagellar beating on the orbits of a swimming cell in a shear flow. We also calculate the effect of the flagellar beating on the rheology of a dilute suspension of micro-swimmers. A three-dimensional model is

Prenatal diagnosis and clinical pregnancy outcome of fetuses with conotruncal defects in a Chinese cohort

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study aimed to explore genetic etiologies of conotruncal defects (CTDs) in fetuses by analyzing the results of different genetic tests and to assess pregnancy outcomes of fetuses with CTD in a Chinese prenatal cohort. Methods A total of 146 fetuses that underwent invasive prenatal genetic testing for CTD at the prenatal ...

A Systematic Review of the Variability of Ventilation Defect Percent Generated From Hyperpolarized Noble Gas Pulmonary Magnetic Resonance Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Hyperpolarized (HP) gas pulmonary MR ventilation images are typically quantified using ventilation defect percent (VDP); however, the test‐retest variability of VDP has not been systematically established in multi‐center trials. Herein, we perform a systematic review of the test‐retest literature on the variability of VDP, and similar metrics,

Chemical composition of wild populations of Thymus vulgaris and Satureja montana in central Catalonia, Spain

JSFA reports, EarlyView.
Abstract Background This study is devoted to determining the chemical composition of essential oils obtained from 13 wild populations of thyme (Thymus vulgaris L.) and 14 populations of winter savory (Satureja montana L.) from the Solsonès region of Catalonia, Spain. The essential oils were obtained by hydrodistillation using a Clevenger apparatus, and
