#1
Gisèle Soubrane
Macular edema is most often clinically defined as an accumulation of serous fluid within the neurosensory retina with increased thickness of the central retina. In exudative age-related macular degeneration the leakage of fluid from the choroidal new vessels may be the origin of macular edema. Their abnormal permeability and the inflammatory reaction are mechanisms involved in this accumulation of fluid, which occurs in all layers. Cystoid macular edema is more often associated with subepithelial occult choroidal neovascularization (CNV) than it is with pre-epithelial classic CNV...

Eutrophication of coastal ecosystems is a global problem that often results in bottom water oxygen deficiency and in turn promotes sediment phosphorus (P) release (A). In order to increase sediment P retention, we injected dissolved aluminum into the anoxic sediment of a eutrophic semi-enclosed bay in the Baltic Sea, thereby inhibiting P recycling and further eutrophication (B). The P concentration in the bay remained at half, as did phytoplankton biomass (C), compared to pre-treatment conditions and compared to the reference bay...

Our understanding of how cells communicate has undergone a paradigm shift since the recent recognition of the role of exosomes in intercellular signaling. In this study, we investigated whether oxygen tension alters the exosome release and miRNA profile from extravillous trophoblast (EVT) cells, modifying their bioactivity on endothelial cells (EC). Furthermore, we have established the exosomal miRNA profile at early gestation in women who develop pre-eclampsia (PE) and spontaneous preterm birth (SPTB). HTR-8/SVneo cells were used as an EVT model...

Despite the known clonal distribution of antibiotic resistance in many bacteria, empiric (pre-culture) antibiotic selection still relies heavily on species-level cumulative antibiograms, resulting in overuse of broad-spectrum agents and excessive antibiotic/pathogen mismatch. Urinary tract infections (UTIs), which account for a large share of antibiotic use, are caused predominantly by Escherichia coli, a highly clonal pathogen. In an observational clinical cohort study of urgent care patients with suspected UTI, we assessed the potential for E...

OBJECTIVES: Guidelines for managing catheter-associated urinary tract infection (CAUTI) and asymptomatic bacteria (ASB) are poorly translated into routine care due in part to cognitive diagnostic errors. This study determines if the accuracy for CAUTI and ASB diagnosis and treatment improves after implementation of a fast and frugal algorithm compared with traditional education methods. MATERIALS AND METHODS: A pre and post-intervention with contemporaneous comparison site involving inpatient and long term care wards at two regional Veterans Affairs Systems in United States...

In the Veterans Health Administration (VHA) system, most orthopedic care takes place in the VA medical centers (VAMCs). Because most patients receiving orthopedic care were referred by adult medicine providers, more widely deploying physician assistants (PAs) in orthopedic medicine might help offset this workload. An orthopedic medicine demonstration project recruited, trained, and positioned PAs in community-based outpatient clinics (CBOCs) to improve access to care. The project involved surgeons at the Houston VAMC instructing five newly employed PAs in a wide range of orthopedic evaluation and management strategies before their assignment to a CBOC...

PURPOSE: Elevated arterial blood pressure (BP) is associated with autonomic dysfunction and impaired haemodynamic control mechanisms. Isometric exercise (IE) training has been demonstrated effective at reducing BP; however, the continuous cardiovascular responses during IE are underinvestigated. We hypothesized that reflex autonomic cardiovascular control is an important mediator in reducing BP. To test our hypothesis, we investigated continuous cardiac autonomic modulation and baroreceptor reflex sensitivity (BRS) in response to IE...

The ingestion of multiple (2:1 glucose:fructose) transportable carbohydrate in beverages at high rates (>78 g·h) during endurance exercise enhances exogenous carbohydrate oxidation, fluid absorption, gut comfort, and performance, relative to glucose alone. But during long-distance endurance competition, athletes prefer a solid-gel-drink format, and the effect size of multiple-transportable carbohydrate is unknown. PURPOSE: To determine the effect of multiple-transportable carbohydrate on triathlon competition performance when ingested within bars, gels, and drinks...

This study describes a retrospective analysis of all women admitted for induction of labour (IoL), carrying a viable singleton foetus, after 34 + 0 weeks of gestation. We aimed to evaluate if foetal sex has an impact on the rate of caesarean delivery following labour induction. Our results demonstrate that among the 1062 women who met the inclusion criteria, 49% (521/1062) were carrying a male foetus. Other than a lower rate of Oxytocin use for the female sex pregnancies, there were no significant differences in pre-labour and labour characteristics between male or female sex pregnancies...

Constructing quantum devices comprises various challenging tasks, especially when concerning their nanoscale geometry. For quantum color centers, the traditional approach is to fabricate the device structure after the non-deterministic placement of the centers. Reversing this approach, we present the controlled generation of quantum centers in silicon carbide (SiC) by focused proton beam in a non-complex manner without need for pre- or post-irradiation treatment. The generation depth and resolution can be predicted by matching the proton energy to the material's stopping power, and the amount of quantum centers at one specific sample volume is tuneable from ensembles of millions to discernible single photon emitters...

Early-life interaction with indigenous intestinal microbes is a prerequisite for healthy immune and metabolic maturation. Human infants acquire their gut microbiota predominantly from the mother. A considerable inoculum of microbes is received by the neonate during vaginal delivery. Recent observations suggest that human gut colonization may be initiated prenatally by microbes in amniotic fluid, but the significance of this phenomenon remains unknown. After birth, neonatal gut colonization is guided by human milk factors, which selectively promote the growth of specific microbes, as well as by live microbes present in human milk...

BACKGROUND: Lymphedema is an iatrogenic complication after breast cancer treatment in which lymph fluid in the affected limb progresses to fat deposition and fibrosis that are amenable to liposuction treatment. Magnetic resonance imaging (MRI) for lymphedema can differentiate fat tissue from fluid, but estimating relative volumes remains problematic. METHODS AND RESULTS: Patients underwent routine bilateral arm MRI both before and after liposuction for advanced lymphedema...

It has been proposed that protein supplementation during resistance exercise training enhances muscle hypertrophy. The degree of hypertrophy during training is controlled in part through activation of satellite cells and myonuclear accretion. PURPOSE: To determine the efficacy of protein supplementation (and the type of protein) during traditional resistance training on myofiber cross-sectional-area, satellite cell content and myonuclear addition. METHODS: Healthy young men participated in supervised whole body progressive resistance training 3d/wk for 12 weeks...

The anatomy of the giraffe (Giraffa camelopardalis Linnaeus, 1758) has been poorly studied, except for the circulatory system. In particular, only a handful of studies have concerned the brain of this species since the first description in 1839. Accordingly, only a very few articles discussing encephalization mentioned the giraffe or used it in their calculations. In this article, we performed a thorough examination of the literature including old and grey, regarding the central nervous system of the giraffe...
