Effects of individualized resistance training prescription with heart rate variability on muscle strength, muscle size and functional performance in older women.

Introduction: This study aimed to investigate whether individualizing autonomic recovery periods between resistance training (RT) sessions (IND) using heart rate variability (HRV), measured by the root mean square of successive R-R interval differences (RMSSD), would lead to greater and more consistent improvements in muscle strength, muscle mass, and functional performance in older women compared to a fixed recovery protocol (FIX).

Methods: Twenty-one older women (age 66.0 ± 5.

Alternative splicing controls pan-neuronal homeobox gene expression.

The pan-neuronally expressed and phylogenetically conserved CUT homeobox gene orchestrates pan-neuronal gene expression throughout the nervous system of As in many other species, including humans, is encoded by a complex locus that also codes for a Golgi-localized protein, called CASP (Cux1 alternatively spliced product) in humans and CONE-1 ("CASP of nematodes") in How gene expression from this complex locus is controlled-and, in , directed to all cells of the nervous system-has not been investigated. We show here that pan-neuronal expression of CEH-44/CUX is controlled by a pan-neuronal RNA splicing factor, UNC-75, the homolog of vertebrate CELF proteins. During embryogenesis, the locus exclusively produces the Golgi-localized CONE-1/CASP protein in all tissues, but upon the onset of postmitotic terminal differentiation of neurons, UNC-75/CELF induces the production of the alternative CEH-44/CUX CUT homeobox gene-encoding transcript exclusively in the nervous system.

Diversity of bacteria of the genus Sphingomonas associated with sugarcane (Saccharum spp.) culm apoplast fluid and their agrotechnological potential.

In sugarcane, sequences related to the genus Sphingomonas have been widely detected by microbiome studies. In this work, the presence of bacteria of this genus was confirmed using culture-dependent and independent techniques. A collection of thirty isolates was obtained using semispecific cultivation conditions, and a specific PCR assay was applied to help confirm the isolates as belonging to the genus.

Comparative analysis of new mScarlet-based red fluorescent tags in Caenorhabditis elegans.

One problem that has hampered the use of red fluorescent proteins in the fast-developing nematode Caenorhabditis elegans has been the substantial time delay in maturation of several generations of red fluorophores. The recently described mScarlet-I3 protein has properties that may overcome this limitation. We compare here the brightness and onset of expression of CRISPR/Cas9 genome-engineered mScarlet, mScarlet3, mScarlet-I3, and GFP reporter knock-ins.
