Diagnostic 5

#1

Comment diagnostiquer la photosynthèse chez les plantes ?

On évalue la production d'oxygène et l'absorption de CO2 en conditions contrôlées.

#2

Quels tests pour mesurer la transpiration des plantes ?

On utilise des pots de pesée pour mesurer la perte d'eau par évaporation.

Cannabinoids in movement disorders.

09 2022
DOI: 10.1016/j.parkreldis.2022.08.014 PMID: 36038457

On the basis of both scientific progress and popular lore, there is growing optimism in the therapeutic potential of cannabis (marijuana) and cannabinoid-based chemicals for movement disorders. There ... In recognition of the high interest and controversial nature of this subject, the meeting committee of the International Parkinson and Movement Disorders Society arranged for a talk on cannabis at the... The endocannabinoid system is strongly tied to motor function and dysfunction, with basic research suggesting several promising therapeutic targets related to cannabinoids for movement disorders. Clin... Further research is greatly needed to better understand the actual clinical benefits and long-term side effects of medical cannabis products for movement disorders indications and populations....

Impaired Metacognition of Voluntary Movement in Functional Movement Disorder.

03 2023
DOI: 10.1002/mds.29303 PMID: 36606550

Motor symptoms in functional movement disorders (FMDs) are experienced as involuntary but share characteristics of voluntary action. Clinical and experimental evidence indicate alterations in monitori... The objective of this study was to test the prediction that FMDs are associated with a reduced ability to make accurate (metacognitive) judgments about self-performed movements.... We compared 24 patients with FMD (including functional gait disturbance, functional tremor, and functional tics) with 24 age- and sex-matched healthy control subjects in a novel visuomotor-metacogniti... Patients and control subjects showed comparable motor performance, response accuracy, and use of the confidence scale. However, visuomotor sensitivity in the trajectory judgment was reduced in patient... Patients with FMD exhibited deficits both when making visuomotor decisions about their own movements and in the metacognitive evaluation of these decisions. Reduced metacognitive insight into voluntar...

Peripherally-induced Movement Disorders: An Update.

2023
DOI: 10.5334/tohm.758 PMID: 37008994
