Background:This systematic review aimed to examine whether dual-task(DT)training was superior to single-task(ST)training in improving DT walking,balance and cognitive functions for individuals with Parkinson’s disease(PD).Methods:Literature search was performed in the following electronic databases:PubMed,the Cochrane Library,Web of Science,and Metstr covering inception to May 10,*** in order to facilitate comparison across trials,we calculated the effect size(Hedges’g)of gait,balance,cognitive,and other parameters under both ST and DT conditions,using the mean change score and standard deviation(SD)of change score of the experimental and control *** controlled trials that examined the effects of DT motor and cognitive training in individuals with Parkinson’s disease were included for this systematic ***:A total of 214 participants recruited from six articles(actually five trials)were involved in this *** terms of walking ability,only double support time and stride time variability showed significant between-group difference(Hedges’g=0.34,0.18,respectively).Compared to ST training group,DT training group had a more improvement effect in laboratory balance measurement(Hedges’g=0.18,1.25),but no significant improvement in clinical balance *** significant between-group differences were observed,thus its training effect on cognitive function was ***:The DT training failed to achieve promising results better than ST training in improving DT walking and balance functions for individuals with *** firm conclusion cannot be drawn at present,due to the limited number of eligible *** sample size and high-quality studies are needed to investigate the effectiveness of DT training in individuals with PD.

Purpose:This study aimed to non-invasively test the hypothesis that(a) short-term lower limb unloading would induce changes in the neural control of force production(based on motor units(MUs) properties) in the vastus lateralis muscle and(b) possible changes are reversed by active recovery(AR).Methods:Ten young males underwent 10 days of unilateral lower limb suspension(ULLS) followed by 21 days of *** ULLS,participants walked exclusively on crutches with the dominant leg suspended in a slightly flexed position(15°-20°) and with the contralateral foot raised by an elevated *** AR was based on resistance exercise(leg press and leg extension) and executed at 70% of each participant’s 1repetition maximum,3 times/*** voluntary isometric contraction(MVC) of knee extensors and MUs properties of the vastus lateralis muscle were measured at baseline,after ULLS,and after *** were identified using high-density electromyography during trapezoidal isometric contractions at 10%,25%,and 50% of the current MVC,and individual MUs were tracked across the 3 data collection ***:We identified 1428 unique MUs,and 270 of them(18.9%) were accurately *** ULLS,MVC decreased by 29.77%,MUs absolute recruitment/derecruitment thresholds were reduced at all contraction intensities(with changes between the 2 variables strongly correlated),while discharge rate was reduced at 10% and 25% but not at 50% *** MVC and MUs properties fully recovered to baseline levels after *** changes were observed in the pool of total as well as tracked ***:Our novel results demonstrate,non-invasively,that 10 days of ULLS affected neural control predominantly by altering the discharge rate of lower-threshold but not of higher-threshold MUs,suggesting a preferential impact of disuse on motoneurons with a lower depolarization ***,after 21 days of AR,the impaired MUs properties were fully restored to baseline levels,highlighting the plas

DNA Tandem Repeats as Iterable Objects to Count Cell Divisions: A Computational Model

引用

Advances in Bioscience and Biotechnology 2024年第4期15卷 207-234页

作者： marco Franco Giulio Regolini MFR Bioengineering Milano Italy

Cell lineages of nematodes are completely known: the adult male of Caenorhabditis elegans contains 1031 somatic cells, the hermaphrodite 959, not one more, not one less;cell divisions are strictly deterministic (as in the great majority of invertebrates) but so far nothing is known about the mechanism used by cells to count precise numbers of divisions. In vertebrates, each species has its invariable deterministic numbers of somites, vertebrae, fingers, and teeth: counting the number of iterations is a widespread process in living beings;nonetheless, it remains an unanswered question and a great challenge in cell biology. This paper introduces a computational model to investigate the possible role of satellite DNA in counting cell divisions, showing how cells may operate under Boolean logic algebra. Satellite DNA, made up of repeated monomers and subject to high epigenetic methylation rates, is very similar to iterable sequences used in programming: just like in the “iteration protocol” of algorithms, the epigenetic machinery may run over linear tandem repeats (that hold cell-fate data), read and orderly mark one monomer per cell-cycle (cytosine methylation), keep track and transmit marks to descendant cells, sending information to cell-cycle regulators.
