Does a decade of soil organic fertilization promote copper and zinc phytoavailability? Evidence from a laboratory biotest with field-collected soil samples.

Despite chronic contamination, long-term organic fertilization tends to decrease copper (Cu) and zinc (Zn) availability in agricultural soils. Root activities of crop plants can also induce substantial changes in rhizosphere chemistry and consequently in the Cu and Zn availability in the rhizosphere. The balance between these two drivers and the overall effect of organic fertilization on Cu and Zn bioavailability to plants (i.

A Rare Case of Unilateral Auditory Neuropathy Induced by Proton Therapy.

Hearing loss (HL) is one of the most common complications of the treatment in head and neck oncology. Most cases of HL are due to the ototoxicity of platinum-based chemotherapy (PBC) - resulting usually in a symmetric bilateral sensorineural hearing loss (SNHL) - or radiotherapy. Radiation-induced SNHL is progressive, permanent, and dose-dependent.

Does a decade of soil organic fertilization promote copper and zinc bioavailability to an epi-endogeic earthworm?

While long-term organic fertilizer (OF) applications tend to decrease copper (Cu) and zinc (Zn) availability in agricultural soils, earthworm bioturbation has been reported to have the opposite effect. Thus, the consequences of OF amendments in earthworm-inhabited soils on Cu and Zn bioavailability to earthworms are still under debate. Here, we assessed the effect of a decade of agronomically realistic OF applications on Cu and Zn availability in earthworm-inhabited soils and the consequences on Cu and Zn bioavailability to earthworms.

Development of a Decision-Aid Form (DAF) for the stratification of care in a French comprehensive cancer center, a tool to support identification of care goals.

Background: For cancer patients, life-threatening complications may be difficult to anticipate, which can lead to complex medical decision-making processes. Since 2015, the Gustave Roussy Cancer Center has used a Decision-Aid Form (DAF), which contains an estimated gradation of care in cases where patients' conditions worsen. In this study, we assessed the acceptability of the DAF and the predictive value of the proposed stratification of care with regard to care delivered and patient's outcomes.

Vestibular and radiological characteristics of children affected by unilateral auditory neuropathy spectrum disorder.

Objective: Auditory neuropathy spectrum disorders (ANSD) are defined by the association of a preserved outer hair cell function and an impaired auditory nerve neural response, and present mostly bilaterally. Unilateral ANSD are consequently only seldom described, and most frequently as isolated cases. This study aims to describe the audiological, vestibular and radiological characteristics of a population of children with unilateral ANSD.

Increased soil pH and dissolved organic matter after a decade of organic fertilizer application mitigates copper and zinc availability despite contamination.

Long-term organic fertilizer (OF) application on agricultural soils is known to induce soil Cu and Zn contamination, along with pH and organic matter changes, which in turn alter the soil Cu and Zn availability. Our study was aimed at assessing Cu and Zn availability in long-term OF-amended soils by distinguishing the importance of increased contamination levels versus pH and organic matter changes in soil. Seventy-four soil samples were collected over time from fields corresponding to three soil types upon which no, mineral, or organic fertilization had been applied over a decade, and thus exhibited a gradient of Cu and Zn contamination, pH, and organic matter concentration.

Differences in sensitivity between earthworms and enchytraeids exposed to two commercial fungicides.

The use of pesticides in crop fields may have negative effects on soil Oligochaeta Annelida, i.e., earthworms and enchytraeids, and thus affect soil quality.

Discovery of potent and selective adamantane-based small-molecule P2X(7) receptor antagonists/interleukin-1beta inhibitors.

A novel series of antagonists of the human P2X7 receptor is described. Modification of substituents enabled identification of compounds selective for the rat P2X7 receptor and provides useful pharmacological tools for evaluation of the role of P2X7 in disease.
