Short-term impact of fire on the total soil microbial and nitrifier communities in a wet savanna.

Savannas are characterized by the coexistence of grasses and trees. Fires are critical for their coexistence, because they decrease the survival of tree seedlings and saplings and their recruitment to the adult stage. In some humid savannas, perennial grasses inhibit nitrification and trees stimulate nitrification, which likely favors coexistence between trees and grasses.

A Unique Case of Gorlin-Goltz Syndrome with Associated Sotos Syndrome.

Both Gorlin-Goltz syndrome and Sotos syndrome are rare genetic conditions showing variable expressiveness. They both are inherited in an autosomal dominant pattern. Since these conditions tend to be multisystemic disorders, the familiarity of various medical specialists with its manifestations may reduce the time necessary for providing a diagnosis, better differentiation of these two conditions, or even the co-existence of two syndromes.

Updated analysis of irritable bowel syndrome: a review of the literature.

Irritable bowel syndrome (IBS) is a chronic pathology with disorders of the bowel-brain interaction, characterized by abdominal pain localized anywhere in the abdomen as well as bowel habit alteration (constipation, diarrhea or mixed), in the absence of any disease that can cause these symptoms. With the updated concepts according to the latest meeting of experts in Rome 2016, our goal is to raise awareness about irritable bowel syndrome, by reviewing the literature regarding definition, classification, pathophysiology, clinical aspects, treatment, prognosis and the future. IBS is a chronic pathology, characterized by abdominal pain, at least 1 day per week in the last 3 months, associated with the alteration of the intestinal bowel habits.

Ancillary Findings on CT Pulmonary Angiograms that are Negative for Pulmonary Embolism.

Context: One advantage of computed tomographic pulmonary angiograms (CTPA) is that they often show pathology in patients in whom pulmonary embolism (PE) has been excluded. In this investigation, we identified the ancillary findings on CTPAs that were negative for PE to obtain an impression of the type of findings shown.

Methods: This was a retrospective analysis of findings on CTPAs that were negative for PE obtained in nine emergency departments between January 2016 - February 2018.

Influence of the residence time of street trees and their soils on trace element contamination in Paris (France).

With the actual increasing interest for urban soils, the evaluation of soil contamination by trace elements and the dynamics of this contamination appear mandatory to preserve plant and thereby human health. Street trees and the associated soil placed in pits located nearby roads could represent convenient indicators of urban and vehicle traffic influences on soils and plants. However, data on these soils remain scarce, many studies investigating park soils rather than street tree soils.

Acoustic tweezers for the life sciences.

Acoustic tweezers are a versatile set of tools that use sound waves to manipulate bioparticles ranging from nanometer-sized extracellular vesicles to millimeter-sized multicellular organisms. Over the past several decades, the capabilities of acoustic tweezers have expanded from simplistic particle trapping to precise rotation and translation of cells and organisms in three dimensions. Recent advances have led to reconfigured acoustic tweezers that are capable of separating, enriching, and patterning bioparticles in complex solutions.

Genotypic variability enhances the reproducibility of an ecological study.

Many scientific disciplines are currently experiencing a 'reproducibility crisis' because numerous scientific findings cannot be repeated consistently. A novel but controversial hypothesis postulates that stringent levels of environmental and biotic standardization in experimental studies reduce reproducibility by amplifying the impacts of laboratory-specific environmental factors not accounted for in study designs. A corollary to this hypothesis is that a deliberate introduction of controlled systematic variability (CSV) in experimental designs may lead to increased reproducibility.

Epigenetic editing of the Dlg4/PSD95 gene improves cognition in aged and Alzheimer's disease mice.

The Dlg4 gene encodes for post-synaptic density protein 95 (PSD95), a major synaptic protein that clusters glutamate receptors and is critical for plasticity. PSD95 levels are diminished in ageing and neurodegenerative disorders, including Alzheimer's disease and Huntington's disease. The epigenetic mechanisms that (dys)regulate transcription of Dlg4/PSD95, or other plasticity genes, are largely unknown, limiting the development of targeted epigenome therapy.

Gradenigo's syndrome: A common infection with uncommon consequences.

Acute otitis media is a common diagnosis encountered by emergency medicine providers. With appropriate antibiotic treatment, patients with otitis media, in general, have minimal long-term sequela from their underlying infection (Limb et al., 2017 [1]).

Genetic mitigation strategies to tackle agricultural GHG emissions: The case for biological nitrification inhibition technology.

Accelerated soil-nitrifier activity and rapid nitrification are the cause of declining nitrogen-use efficiency (NUE) and enhanced nitrous oxide (NO) emissions from farming. Biological nitrification inhibition (BNI) is the ability of certain plant roots to suppress soil-nitrifier activity, through production and release of nitrification inhibitors. The power of phytochemicals with BNI-function needs to be harnessed to control soil-nitrifier activity and improve nitrogen-cycling in agricultural systems.

Characterization of solid airborne particles deposited in snow in the vicinity of urban fossil fuel thermal power plant (Western Siberia).

Recognition and detailed characterization of solid particles emitted from thermal power plants into the environment is highly important due to their potential detrimental effects on human health. Snow cover is used for the identification of anthropogenic emissions in the environment. However, little is known about types, physical and chemical properties of solid airborne particles (SAP) deposited in snow around thermal power plants.
