Plants shape and interact continuously with their rhizospheric microbiota, which play a key role in plant health and resilience. However, plant-associated microbial community can be shaped by several factors including plant phenotype and cropping system. Thus, understanding the interplay between microbiome assembly during the onset of plant-pathogen interactions and long-lasting resistance traits in ligneous plants remains a major challenge.

In the current meta-analysis, we synthesized the literature on (1) the contribution of genetic and environmental factors to NDDs, (2) the genetic and environmental overlap between different NDDs, and (3) the co-occurrence between NDDs and disruptive, impulse control and conduct disorders (DICCs). Searches were conducted across three platforms: Web of Science, Ovid Medline and Ovid Embase.

Despite the agroeconomic significance of wheat, the mechanisms underlying its induced defense responses remain obscure. We reveal here, using combined transcriptomic, metabolomic and cytologic approach, that the lipopeptide mycosubtilin from the beneficial bacterium , protects wheat against through a dual mode of action (direct and indirect) and that the indirect one relies mainly on the priming rather than on the elicitation of plant defense-related mechanisms.

Common methods used to quantify the mycorrhization of roots are based on microscopic visualization of stained fungal structures within the cortical cells. While this method is readily accessible, it remains time-consuming and does not allow checking of the symbiosis vitality.

Suspended particles are major organic carbon substrates for heterotrophic microorganisms in the mesopelagic ocean (100-1000 m). Nonetheless, communities associated with these particles have been overlooked compared with sinking particles, the latter generally considered as main carbon transporters to the deep ocean. This study is the first to differentiate prokaryotic communities associated with suspended and sinking particles, collected with a marine snow catcher at four environmentally distinct stations in the Scotia Sea.

We provide a) raw neural signals (sampled at 30 kHz), b) time stamps and spike waveforms of offline sorted single and multi units (93/49 and 156/19 SUA/MUA for the two monkeys, respectively), c) trial events and the monkey's behavior, and d) extensive metadata hierarchically structured via the odML metadata framework (including quality assessment post-processing steps, such as trial rejections). The dataset of one monkey contains a simultaneously saved record of the local field potential (LFP) sampled at 1 kHz.

Here we show occurrence of seasonal stratification and generally low concentrations of dissolved inorganic combined nitrogen, and high molecular nitrogen (N) to argon ratio, thus suggesting seasonal loss to N in anoxic hypolimnia of several dam-reservoirs. However, N-experiments yielded low rates of denitrification, anaerobic ammonium oxidation and dissimilatory nitrate reduction to ammonium-except in the presence of methane (CH) that caused ~12-fold increase in denitrification.

Representative sampling indicated that municipal water supplies represent < 1% of the water sources. Residents rely on privately constructed and maintained boreholes that are supplemented by commercially packaged bottled and sachet drinking water.
View Article and Find Full Text PDFOxygen minimum zones (OMZs) caused by water column stratification appear to expand in parts of the world's ocean, with consequences for marine biogeochemical cycles. OMZ formation is often fueled by high surface primary production, and sinking organic particles can be hotspots of interactions and activity within microbial communities. This study investigated the diversity of OMZ protist communities in two biomass size fractions (>30 and 30-1.

The aim of this work was to develop an analytical method capable of determining the presence of anisatin in star anise. This neurotoxin may induce severe side effects such as epileptic convulsions. It is therefore of prime importance to have rapid and accurate analytical methods able to detect and quantify anisatin in samples that are purportedly edible star anise.

Therefore, an efficient multi-targeted method was developed to screen selected botanicals of interest in herbal food supplements. Liquid chromatography coupled with a hybrid triple quadrupole linear ion trap was used for this purpose.

Aim: We investigated whether preterm birth affects later visuocognitive function and, in particular, whether it affects global and configural perceptual processing differently.
Method: We compared the performance of 21 healthy preterm children (8 females, 13 males; mean age 7 y 8 mo, SD 8 mo; mean gestational age 29.3 wks, SD 1.
With increasing numbers of preterm infants surviving, the impact of preterm birth on later cognitive development presents a major interest. This study investigates the impact of preterm birth on later dorsal- and ventral-stream functioning. An atypical pattern of performance was found for preterm children relative to full-term controls, but in the dorsal-drawing task only.

The natural evolution of a small aneurysm into a giant aneurysm is rarely observed. We discuss the pathophysiology of the development and growth of such aneurysms through a review of the literature.

The authors report one case of choroid metastasis and one case of orbital metastasis from a prostatic carcinoma. A review of the literature confirms the exceptional nature of these metastatic sites (28 cases), which constitute a poor short-term prognostic factor. Palliative hormonal treatment allows regression of the ophthalmic signs without modifying the course of the disease.

The management of intracavernous meningiomas remains controversial. The variety of methods of treatment reflects the difficulty of treating primary meningiomas of the cavernous sinus. Twelve personal cases and a review of the literature permit a choice between a direct surgical approach with or without radiotherapy, only radiation therapy or with no therapy.
