Purpose This study aimed to describe self-selected intensity and its relationship to performance during a high-intensity all-out judo protocol,and to verify whether athletes with different anaerobic speed reserve(ASR)perform differently during a high-intensity all-out interval uchi-komi(judo-specific skill).Methods We analyzed the performance of 28 judo athletes as a whole group and divided into groups,according to their *** performed several judo-specific protocols using a specific skill:maximal speed sprint(MSS)and maximal aerobic speed(MAS),and high-intensity intermittent uchi-komi protocol(12×20 s all-out:10 s passive recovery).Results The main results demonstrated a decrease in the number of repetitions and an increase in heart rate across the *** with greater ASR performed a higher number of repetitions,compared to the low ASR group,and they were able to exercise at a higher percentage of the MAS(low ASR=126%;SD=13%;high ASR=152%,SD=l9%)and at a lower percentage of MSS compared to the low ASR group(low ASR=84%,SD=7%;high ASR=76%,SD=11%).However,both groups exercised at a similar percentage of their own ASR during the protocol(low ASR=50%,SD=20%;high ASR=53%,SD=19%).Conclusions Athletes with different ASR seem to set their pace at around 50%of their ASR within an all-out uchi-komi ***,the ASR is useful for predicting performance during high-intensity judo-specific interval exercise intervals.

Let f, g: X → Y be maps from a compact infra-nilmanifold X to a compact nilmanifold Y with dim X ≥ dim Y. In this note, we show that a certain Wecken type property holds, i.e., if the Nielsen number N(f, g) vanishes then f and g are deformable to be coincidence free. We also show that if X is a connected finite complex X and the Reidemeister coincidence number R(f, g) = ∞ then f ～ f' so that C(f', g) = {x ∈ X | f'(x) = g(x)} is empty.

Alzheimer's disease is a severe, highly disabling neurodegenerative disease, clinically characterized by a progressive decline in cognitive functions, and is the most common form of dementia in the elderly. For decades, the search for disease-modifying therapies has focused on the two main Alzheimer's disease histopathological hallmarks, seeking to prevent, mitigate, or clear the formation of extracellular aggregates of β-amyloid peptide and intracellular neurofibrillary tangles of tau protein, although without clinical success. Mesenchymal stem cell-based therapy has emerged as a promising alternative for the treatment of Alzheimer's disease, especially because it also targets other crucial players in the pathogenesis of the disease, such as neuroinflammation, synaptic dysfunction/loss, oxidative stress, and impaired neurogenesis. Herein, we review current knowledge of the therapeutic potential of mesenchymal stem cells and their extracellular vesicles for Alzheimer's disease, discussing the most recent findings in both preclinical and clinical trials as well as how advanced technologies have helped to overcome some limitations and contributed to stimulate the development of more effective treatments.
