An expert working group was set up at the initiative of the French Ministry of Sports with the objective of harmonising the management of sport related concussion (SRC) in France, starting with its definition and diagnosis criteria.

Definition A clinical definition in 4 points have been established as follows Concussion is a brain injury 1) caused by a direct or indirect transmission of kinetic energy to the head; 2) resulting in an immediate and transient dysfunction of the brain characterised by at least one of the following disorders a) Loss of consciousness, b) loss of memory, c) altered mental status, d) neurological signs; 3) possibly followed by one or more functional complaints (concussion syndrome); 4) the signs and symptoms are not explained by another cause. Diagnosis criteria In the context of the direct or indirect transmission of kinetic energy to the head, the diagnosis of concussion may be asserted if at least one of the following signs or symptoms, observed or reported, is present within the first 24hours and not explained by another cause 1) loss of consciousness; 2) convulsions, tonic posturing; 3) ataxia; 4) visual trouble; 5) neurological deficit; 6) confusion; 7) disorientation; 8) unusual behaviour; 9) amnesia; 10) headaches; 11) dizziness; 12) fatigue, low energy; 13) feeling slowed down, drowsiness; 14) nausea; 15) sensitivity to light/noise; 16) not feeling right, in a fog; 17) difficulty concentrating.

Sharing the same definition and the same clinical diagnostic criteria for concussion is the prerequisite for common rules of management for all sports and should allow the pooling of results to improve our knowledge of this pathology.

This study aims to elucidate the molecular mechanism of LOXL1-AS1 in proliferation and migration of trophoblast cells.

We have used specific small interfering RNAs (si-RNA) and microRNA (mi-RNA) to knock down the target gene or m-RNA. In this regard we used following siRNAs si-NC, si-LOXL1-AS1, pcDNA-NC, pcDNA-LOXL1-AS1, miR-NC, miR-515-5p. These si-RNA and miRNA were transfected into JeG-3 cells. Real-time quantitative PCR (RT-qPCR) was used to detect the expressions of LOXL1-AS1 and miR-515-5p. selleck products Western blot was used to detect Cyclin D1, matrix metalloproteinase 2 (MMP2), matrix metalloproteinases 9 (MMP9), phosphorylated p65 (p-p65), profilin of phosphorylated nuclear transcription factor κB (p-IκBα). MTT assay was used to detect cell survival rate, and the luciferase assay was used to detected the targeting relationship of LOXL1-AS1 and miR-515-5p.

Our results showed that human placental trophoblast cells had higher level of LOXL1-AS1 in comparison to human choriocarcinoma cells, however, human placental trophoblast cells had lower level of miR-515-5p. In addition, the expression of CyclinD1, MMP2, MMP9 were significantly decreased in JeG-3 cell lines. We observed lower cell survival rate and lower cell migration number in JeG-3 cell lines. Our results demonstrated that LOXL1-AS1 could target miR-515-5p, and subsequently reverse the inhibitory effect of LOXL1-AS1 on proliferation and migration in JEG-3 cells. Also, lower expressions of p-p65 and p-IкBα in JeG-3 cells showed that miR-515-5p could reversed the inhibitory effect of LOXL1-AS1 on NF-κB signaling pathway.

The low expression of LOXL1-AS1 inhibits the proliferation and migration of human choriocarcinoma cells, which might be related to miR-515-5p and NF-κB signaling pathways.

As such AGR2, often found overexpressed in adenocarcinomas, contributes to tumour development by enhancing ER proteostasis. We previously demonstrated that AGR2 is secreted (extracellular AGR2 (eAGR2)) in the tumour microenvironment and plays extracellular roles independent of its ER functions. Herein, we show that eAGR2 triggers cell proliferation and characterize the underlying molecular mechanisms. We demonstrate that eAGR2 enhances tumour cell growth by repressing the tumour suppressor p21CIP1. Our findings shed light on a novel mechanism through which eAGR2 behaves as a growth factor in the tumour microenvironment, independently of its ER function, thus promoting tumour cell growth through repression of p21CIP1. Our results provide a rationale for targeting eAGR2/p21CIP1-based signalling as a potential therapeutic target to impede tumour growth.

Dance is a multidomain activity that combines aerobic, coordination and cognitive exercise. This music-associated physical and cognitive exercise is a leisure activity that motivates people, elicits emotions, and avoids boredom, promoting adherence to practice. Continuing physical activity is of paramount importance, since cognitive benefits tend to disappear or even reverse when training ceases.

The question we addressed in this systematic review is what influence dance has on the brain and cognition of healthy middle-aged and older adults.

We systematically reviewed the effects of dance on brain and cognition in older adults using MEDLINE, Psyc-Info, PubMed and Scopus databases.

After screening 1051 studies, thirty-five met the eligibility inclusion criteria. These studies showed that dance improves brain structure and function as well as physical and cognitive functions.

The protective effect of dance training on cognition in older adults, together with the possibility of adapting intensity and style to suit possible physical limitations makes this activity very suitable for older adults.
