Epimuscular myofascial force transmission between nerve and myotendinous unit: A shear-wave elastography study.

Introduction: Epimuscular myofascial force transmission can occur bidirectionally between muscles and nerves through a connecting neurovascular tract. The purpose of this study was to determine whether a neurodynamic stress test produces stiffness changes in the adjacent myotendinous complex. The authors also assessed which anatomical variables had an impact on elasticity changes provoked by the maneuver.

Effectiveness of simultaneous bilateral visual diaphragm biofeedback under low back pain: influence of age and sex.

The aim of the present study was to determine the effectiveness of simultaneous bilateral visual diaphragm biofeedback (BFB) from ultrasonography in conjunction with inspiratory muscle training (IMT) on diaphragmatic thickness during normal breathing and respiratory and clinical outcomes in patients with non-specific low back pain (NSLBP) and determine the influence of age and sex. A single-blind randomized clinical trial was carried out (NCT04582812). A total sample of 96 patients with NSLBP was recruited and randomized by sex-based stratification into IMT ( = 48) and BFB + IMT ( = 48) interventions over 8 weeks.

A Secondary Analysis of Gender Respiratory Features for Ultrasonography Bilateral Diaphragm Thickness, Respiratory Pressures, and Pulmonary Function in Low Back Pain.

The aim of the present study was to determine the gender respiratory differences of bilateral diaphragm thickness, respiratory pressures, and pulmonary function in patients with low back pain (LBP). A sample of 90 participants with nonspecific LBP was recruited and matched paired by sex (45 women and 45 men). Respiratory outcomes included bilateral diaphragm thickness by ultrasonography, respiratory muscle strength by maximum inspiratory (MIP) and expiratory (MEP) pressures, and pulmonary function by forced expiratory volume during 1 s (FEV), forced vital capacity (FVC) and FEV/FVC spirometry parameters.

Nematostatic activity of isoprenylated guanidine alkaloids from Pterogyne nitens and their interaction with acetylcholinesterase.

Although new nematicides have appeared, the demand for new products less toxic and more efficient for the control of plant-parasitic nematodes are still high. Consequently, studies on natural secondary metabolites from plants, to develop new nematicides, have increased. In this work, nineteen extracts from eleven Brazilian plant species were screened for activity against Meloidogyne incognita.

These compounds can come from a variety of sources, including organic residues. In this study, we identified in the cassava wastewater volatiloma a molecule with potential to be developed as a new fumigant nematicide.

Antioxidant vitamin supplementation on muscle adaptations to resistance training: A double-blind, randomized controlled trial.

Objectives: The aim of this study was to examine whether antioxidant vitamin supplementation with vitamin C (VitC) and vitamin E (VitE) affects the hypertrophic and functional adaptations to resistance training in trained men.

Methods: This was a double-blind, randomized controlled trial in which participants were supplemented daily with VitC and VitE ( n = 12) or placebo ( n = 11) while completing a 10-wk resistance training program accompanied by a dietary intervention (300 kcal surplus and adequate protein intake) designed to optimize hypertrophy. Body composition (dual-energy x-ray absorptiometry), handgrip strength, and one-repetition maximum (1-RM), maximal force (F0), velocity (V0), and power (Pmax) were measured in bench press (BP) and squat (SQ) tests conducted before and after the intervention.

(R)-Carvone is a potential soil fumigant against Meloidogyne incognita whose likely enzymatic target in the nematode is acetylcholinesterase.

To contribute to the development of new fumigant nematicides for the control of the plant-parasitic nematode Meloidogyne incognita, this study started with 31 volatile organic compounds reported as toxic to nematodes. At 500 μg/mL, α-ionone, (S)-carvone, (R)-carvone, 2-methylpropyl acetate, undecan-2-one, decan-2-one, and dodecan-2-one caused mortalities to M. incognita second-stage juveniles (J2) that were similar to those obtained with the commercial nematicides carbofuran (170 μg/mL) and fluensulfone (42.

Introduction: Diastasis rectus abdominis (DRA) is defined as the separation of the rectus abdominis along the linea alba. This condition can occur in both sexes, being frequent in women during pregnancy and pospartum. There is little evidence on the consequences of DRA on the quality of life of women.

Methyl Esters of ()-Cinnamic Acid: Activity against the Plant-Parasitic Nematode and Interaction with Histone Deacetylase.

()-Cinnamaldehyde is very active against but has low persistence in soil. To circumvent this problem, esters of cinnamic acid were evaluated as a substitute for ()-cinnamaldehyde. The best results under assays with second-stage juveniles (J2) were obtained for the methyl esters of ()--fluoro- (), ()--chloro- (), and ()--bromocinnamic acid (), which showed lethal concentrations to 50% (LC) J2 of 168, 95, and 216 μg/mL, respectively.

Exercise Training and Interventions for Coronary Artery Disease.

Coronary artery disease (CAD) may be considered a main cause of mortality and the prevalence of CAD is increasing nowadays, leading to high health costs in many countries. Despite the fact of the regression of the atherosclerotic plaque, the decrease in blood viscosity and the growth of collateral vessels have been proposed as improvements that CAD patients may obtain under exercise performance. Thus, the present narrative review aimed to carry out a brief specific analysis of the results achieved when performing endurance, strength or inspiratory muscle training.

Background: Chronic low back pain (LBP) has been stated as one of the main health concerns in the XXI century due to its high incidence.

Objective: The objective of this study was to determine the effects of an 8-week program of hypopressive abdominal gymnastics (HAG) on inspiratory muscle strength, diaphragm thickness, disability and pain in patients suffering from non-specific chronic LBP.

Methods: A total of 40 patients with chronic LBP were randomly divided into two groups.

The combination of two Bacillus strains suppresses Meloidogyne incognita and fungal pathogens, but does not enhance plant growth.

Background: The combination of biocontrol agents is a desirable strategy to improve control efficacy against the root-knot nematode (RKN) Meloidogyne incognita under field conditions. However, strains compatibility is generally tested in vitro and incompatible combinations are normally not further examined in experiments in planta. Therefore, there is virtually no information on the performance of incompatible strains.
