Muscle coordination strategies during Functional Reach across multiple directions in healthy individuals.

Purpose: Understanding the neuromuscular strategies underlying postural stability is crucial for evaluating motor control and balance. This study examines muscle coordination during several variations of the Functional Reach (FR)-unilateral Functional Reach (uniFR), bilateral Functional Reach (biFR), and Lateral Reach (LR)-in healthy young adults. This study aims to establish a reference baseline for these tasks and assess whether fundamental motor control strategies are preserved across FR variations, despite distinct biomechanical demands and directional stability components.

Fatigue-induced alterations in the spatial distribution of lumbar erector spinae activity in older versus young adults.

Purpose: This study examined differences in the spatial distribution of lumbar erector spinae (LES) muscle activity during a submaximal isometric trunk extension contraction between older and younger adults.

Methods: Thirteen older adults (OLDER) and thirteen young adults (YOUNG) participated. High-density surface electromyography signals were recorded from the LES muscle during an isometric trunk extension task at 30% of maximal voluntary isometric force until failure.

Aflatoxins in pistachio spread produced and commercialised in Southern Italy.

In this study, the presence of aflatoxins (AFB1, AFB2, AFG1, and AFG2) in 135 samples of pistachio spreads, marketed and produced from 2016 to 2020 in Southern Italy, was determined by a validated High-Performance Liquid Chromatography with fluorescence detection method. The obtained results showed variable contamination across the years, with a significant increase in 2020 for AFB1 and AFG1 ( < 0.05), showing mean levels of 1.

Toxic metals and metalloids in collagen supplements of fish and jellyfish origin: Risk assessment for daily intake.

Aim: We examined marine collagen supplements derived from fish and jellyfish for the presence of toxic metals and metalloids (Pb, Cd, Cr, Hg, and As). A risk assessment was also carried out by converting the obtained concentrations into average daily doses (ADDs) and comparing them with tolerable daily intakes (TDIs) to evaluate potential health risks associated with long-term consumption.

Methods: The levels of Pb, Cd, Cr, and As in marine collagen samples were quantified using inductively coupled plasma mass spectrometry (ICP-MS).

Neuromuscular electrical stimulation reduces spinal excitability in Multiple Sclerosis patients with spasticity symptoms.

Background: The use of neuromuscular electrical stimulation (NMES) has been recently proposed in patients with neurological diseases, such as spinal cord injuries and stroke, to improve symptoms of spasticity, resulting in both increased control of voluntary movements and improved functional ability in daily activities. Despite several authors suggest that these results could be related to a reduced spinal excitability, which is known to be higher in spastic patients, no previous studies investigated the neurophysiological mechanisms underlying the effect of NMES in reducing spasticity. In addition, there are no studies in the literature adopting NMES to improve spasticity in patients with Multiple Sclerosis (MS).

Consumption of lettuce with seaweed extract biostimulant application improved iron homeostasis in a randomized interventional trial of healthy individuals.

Minerals have key roles in the body's metabolism and homeostasis. Biostimulants application to vegetables, such as seaweed extracts derived from Ecklonia maxima (SwE), is a useful agronomic approach to improve crop yield and quality by a naturally functionalizing process. We hypothesized that SwE biostimulants would impact the minerals profile of the lettuce and the consumption of lettuce with SwE application would affect blood minerals concentration in the health population.

Trace elements in feathers, pectoral plumage, and blood of griffon vultures (Gyps fulvus) from a captive environment of Southern Italy.

Heavy metals and metalloids are increasingly recognised as a threat to avian health, especially in species at the top of the food chain such as vultures. Griffon Vultures (Gyps fulvus) are ideal bioindicators for studying environmental contamination due to their scavenging habits and territorial behavior. In this study, we analysed the concentrations of six trace elements (Cd, Pb, Cr, Sb, Ni, and Cu) in feathers, pectoral plumage, and blood samples of Griffon Vultures from a captive environment in Sicily, Southern Italy, using an ICP-MS method.

Frequency-dependent effects of superimposed NMES on spinal excitability in upper and lower limb muscles.

Superimposing neuromuscular electrical stimulation (NMES) on voluntary contractions has proven to be highly effective for improving muscle strength and performance. These improvements might involve specific adaptations occurring at cortical and spinal level. The effects of NMES on corticospinal activation seem to be frequency dependent and differ between upper and lower limb muscles.

Metal Levels in Striped Dolphins () and Common Dolphins () Stranded along the Sicilian Coastlines of the Mediterranean Sea.

Dolphins, top predators of the aquatic food chain, are used as sentinel species of marine pollution as they are sensitive to environmental changes and able to accumulate a large content of contaminants. Several EU directives promote study of marine mammalians as bio-indicators to evaluate the presence of contaminants in the aquatic environment, such as the Mediterranean Sea, which is rich in environmental pollutants due to its geographic and geo-morphological characteristics. The aim of this study was to evaluate the content of toxic and essential metals and metalloids (Hg, Pb, Cd, As, Se and Zn), through ICP-MS analysis, in organs/tissues (liver, muscle, lung, kidney and skin) of striped dolphins () and common dolphins ) stranded along the Sicilian coastlines of the Mediterranean Sea.

Microbiological and Toxicological Investigations on Bivalve Molluscs Farmed in Sicily.

Bivalves can concentrate biological and chemical pollutants, causing foodborne outbreaks whose occurrence is increasing, due to climatic and anthropic factors that are difficult to reverse, hence the need for improved surveillance. This study aimed to evaluate the hygienic qualities of bivalves sampled along the production and distribution chain in Sicily and collect useful data for consumer safety. Bacteriological and molecular analyses were performed on 254 samples of bivalves for the detection of enteropathogenic , spp.

Neuromuscular Electrical Stimulation Does Not Influence Spinal Excitability in Multiple Sclerosis Patients.

(1) : Neuromuscular electrical stimulation (NMES) has beneficial effects on physical functions in Multiple sclerosis (MS) patients. However, the neurophysiological mechanisms underlying these functional improvements are still unclear. This study aims at comparing acute responses in spinal excitability, as measured by soleus Hoffmann reflex (H-reflex), between MS patients and healthy individuals, under three experimental conditions involving the ankle planta flexor muscles: (1) passive NMES (pNMES); (2) NMES superimposed onto isometric voluntary contraction (NMES+); and (3) isometric voluntary contraction (ISO).

Determination of Mycotoxins in Plant-Based Meat Alternatives (PBMAs) and Ingredients after Microwave Cooking.

In this study, we investigate the role of microwave cooking in reducing mycotoxin contamination in plant-based food matrices, with a focus on veggie burgers (purchased and home-made) and their ingredients (soybean, potatoes, zucchini, carrots). Two different conditions were studied (Max-Min) that were 800 W for 60 s and 800 W for 90 s, respectively. The degradation patterns of aflatoxins (AFB1, AFB2, AFG1, AFG2), fumonisins (FB1, FB2, FB3), trichothecenes (T2, HT2, ZEA), and ochratoxin A (OTA) were studied.

Marine phycotoxin levels in shellfish-14 years of data gathered along the Italian coast.

Along the Italian coasts, toxins of algal origin in wild and cultivated shellfish have been reported since the 1970s. In this study, we used data gathered by the Veterinary Public Health Institutes (IZS) and the Italian Environmental Health Protection Agencies (ARPA) from 2006 to 2019 to investigate toxicity events along the Italian coasts and relate them to the distribution of potentially toxic species. Among the detected toxins (OA and analogs, YTXs, PTXs, STXs, DAs, AZAs), OA and YTX were those most frequently reported.

Polyphenols of white lupin ( L.) seeds cultivated in Southern Italy by a LC-HRMS method.

In this work we examined the contents of 14 polyphenols in white lupin ( L.) samples cultivated in Southern Italy by the optimisation and validation of a LC-HRMS method. The validation of the LC-HRMS method showed linearity results r > 0.

Comparison of acute responses in spinal excitability between older and young people after neuromuscular electrical stimulation.

Purpose: This study aims at comparing acute responses in spinal excitability, as measured by H-reflex, between older and young individuals, following a single session of NMES superimposed onto voluntary isometric contractions of the ankle plantar-flexor muscles (NMES+), with respect to passive NMES (pNMES) and voluntary isometric contractions only (ISO).

Methods: Thirty-two volunteers, 16 older (OLDER) and 16 young (YOUNG), were asked to sustain a constant force at 20% of maximal voluntary isometric contraction (MVIC) of the ankle plantar-flexor muscles in the dominant limb during each of the 3 conditions (NMES+ , pNMES and ISO). Fifteen repetitions of 6 s were performed, with a resting interval of 6 s between repetitions.

Adjustments in the motor unit discharge behavior following neuromuscular electrical stimulation compared to voluntary contractions.

The application of neuromuscular electrical stimulation superimposed on voluntary muscle contractions (NMES+) has demonstrated a considerable potential to enhance or restore muscle function in both healthy and individuals with neurological or orthopedic disorders. Improvements in muscle strength and power have been commonly associated with specific neural adaptations. In this study, we investigated changes in the discharge characteristics of the tibialis anterior motor units, following three acute exercises consisting of NMES+, passive NMES and voluntary isometric contractions alone.

Acute effects of neuromuscular electrical stimulation on cortical dynamics and reflex activation.

Superimposing neuromuscular electrical stimulation (NMES) on voluntary muscle contractions has shown the potential to improve motor performance even more than voluntary exercise alone. Nevertheless, the neurophysiological and neurocognitive mechanisms underlying this technique are still unclear. The aim of this study was to investigate the acute responses in spinal excitability and brain activity following three conditions: NMES superimposed on isometric contractions (NMES + ISO), passive NMES, and voluntary isometric contractions (ISO).

"Posture first": Interaction between posture and locomotion in people with low back pain during unexpectedly cued modification of gait initiation motor command.

The ability to adapt anticipatory postural adjustments (APAs) in response to perturbations during single-joint movements is altered in people with chronic low back pain (LBP), but a comprehensive analysis during functional motor tasks is still missing. This study aimed to compare APAs and stepping characteristics during gait initiation between people with LBP and healthy controls, both in normal (without cue occurrence) condition and when an unexpected visual cue required to switch the stepping limb. Fourteen individuals with LPB and 10 healthy controls performed gait initiation in normal and switch conditions.

Do the Testing Posture and the Grip Modality Influence the Shoulder Maximal Voluntary Isometric Contraction?

Assessing and monitoring shoulder strength is extremely important during rehabilitation. A fixed dynamometer represents a valid and inexpensive assessment method. However, it has not been studied whether posture and grip modality influence shoulder muscle strength.

Background: The Loggerhead sea turtle () is a marine reptile belonging to a monophyletic group of chelonians. As these animals are long-lived, they have the ability to accumulate pollutants.

Aim: To collect epidemiological data on toxic metals in marine Loggerhead sea turtles.

NMES superimposed on movement is equally effective as heavy slow resistance training in patellar tendinopathy.

Objective: This study aimed at investigating the effectiveness of an 8-week training protocol, based on neuromuscular electrical stimulation of the quadriceps, which was superimposed onto voluntary exercise (NMES+), in comparison to a traditional heavy slow resistance training (HSRT), in individuals with patellar tendinopathy.

Methods: Thirty-two physically active participants, aged: 33.6±10.

First Report on the Presence of Toxic Metals and Metalloids in East Asian Bullfrog () Legs.

We examined the presence of As, Cr, Cd, and Pb in 42 samples of farmed East Asian bullfrog (Hoplobatrachus rugulosus) from Vietnam and Thailand by inductively coupled plasma-mass spectrometry (ICP-MS). An estimation of the dietary intake and exposure to the toxic elements analysed was also carried out. The results showed very high As levels, with mean values of 0.

Tremor, finger and hand dexterity and force steadiness, do not change after mental fatigue in healthy humans.

The effects of mental fatigue have been studied in relation to specific percentages of maximal aerobic or anaerobic efforts, maximal voluntary contractions or the performance of sport specific skills. However, its effects on tremor, dexterity and force steadiness have been only marginally explored. The present work aimed at filling this gap.
