Article Synopsis
  • Carnobacterium maltaromaticum is a type of lactic acid bacteria that can produce various bacteriocins, which are useful in biotechnological applications.
  • The study introduces a new strain, C. maltaromaticum CM22, isolated from a salmon gut, which produces a unique bacteriocin called piscicolin CM22.
  • This bacteriocin shows antimicrobial activity against certain harmful Gram-positive bacteria but is ineffective against Gram-negative species, suggesting potential for applications in the agri-food industry.

Hamstring injuries in soccer continue to be a challenge for professionals who work with soccer players daily. Although its origin is multifactorial, the proper management of neuromuscular fatigue during the training microcycle is a very important factor to consider. There are no clear guidelines regarding the weekly distribution of certain exercises that demand the hamstrings.

Article Synopsis
  • * The study analyzed urine samples from 13 healthy and 38 critically ill newborns using advanced mass spectrometry techniques to identify and quantify 180 metabolites, revealing significant differences in metabolic profiles between the groups.
  • * Findings highlighted that metabolites related to conditions like bronchopulmonary dysplasia and exposure to viruses show dysregulation in critically ill infants, suggesting urine analysis can provide crucial insights into early metabolic changes linked to severe perinatal outcomes.

In this work, two autochthonous LAB strains ( BPF2 and ST6), isolated from spontaneously fermented sausages produced in Spain, were tested to produce Spanish fermented sausages () in pilot plants, due to their promising technological and anti-listerial activity. These products were compared with a sample obtained with a commercial starter (RAP) and a spontaneously fermented control sample. Physico-chemical parameters, microbial counts, metagenomic analysis, biogenic amines content and organoleptic profile of the obtained samples were studied to assess the performances of the native starters.

Type 1 diabetes mellitus (T1DM) is a chronic endocrine disease that results from autoimmune destruction of pancreatic insulin-producing β cells, which can lead to microvascular (, retinopathy, neuropathy, and nephropathy) and macro-vascular complications (, coronary arterial disease, peripheral artery disease, stroke, and heart failure) as a consequence of chronic hyperglycemia. Despite the widely available and compelling evidence that regular exercise is an efficient strategy to prevent cardiovascular disease and to improve functional capacity and psychological well-being in people with T1DM, over 60% of individuals with T1DM do not exercise regularly. It is, therefore, crucial to devise approaches to motivate patients with T1DM to exercise, to adhere to a training program, and to inform them of its specific characteristics (, exercise mode, intensity, volume, and frequency).

  • SARS-CoV-2 infection alters human immunometabolism, leading to significant long-term effects, with an estimated 650 million people infected and 620 million recovered since the pandemic began.
  • The World Health Organization has acknowledged post-COVID syndrome as a new condition, prompting guidelines for management, but the underlying molecular mechanisms behind various symptoms remain unclear.
  • A study evaluated the clinical and lipidomic profiles of recovered patients two years post-infection, finding persistent symptoms like fatigue and musculoskeletal issues, alongside notable metabolic dysregulations that could inform future diagnostics and treatments.

Spoilage of fish due to microbiological activity is one of the biggest problems found by producers to take fresh fish products to customers. It is necessary packaging improvements to be able to increase fish shelf life and, thus, be able to travel further and to keep product freshness longer at customer's houses. In the present work, a new material is developed for fish packaging in modified atmosphere (MAP).

Controlling in food is a major challenge, especially because it can persist for years in food processing plants. The best option to control this pathogen is the implementation of effective cleaning and disinfection procedures that guarantee the safety and quality of the final products. In addition, consumer trends are changing, being more aware of the importance of food safety and demanding natural foods, minimally processed and free of chemical additives.

New PET and nanosepiolite materials are produced for its application in innovative packaging with better performance. In our previous work, we demonstrate that the use of different percentages of sepiolite modified with different organosilanes improved mechanical and barrier properties of PET. Nanocomposites permeability can decrease up to 30% compared to that of pure PET and the mechanical analyses show that, although PET nanocomposites are more brittle than virgin PET, they are also harder.

: The mechanical properties of resistance-training machines are a variable that may help to optimize sports performance and injury prevention protocols. The purpose of this study was to examine two non-gravity-dependent training modalities on muscle structure and function. : Eighteen professional handball players were randomly divided into two experimental groups: 1) iso-inertial flywheel training (FW) and 2) pneumatic resistance training (PN).

Article Synopsis
  • Placenta-derived exosomes facilitate cellular communication between the mother and fetus, with their composition varying in pregnancy disorders like gestational diabetes mellitus (GDM).
  • This study isolates and characterizes placental exosomes from the urine of GDM patients throughout all three trimesters, confirming their presence with advanced imaging and analysis techniques.
  • The research reveals that certain microRNAs linked to metabolic pathways are downregulated in GDM, suggesting urinary exosomes could serve as valuable biomarkers and therapeutic targets for managing the condition.

This study aimed to investigate the influence of unknown additional eccentric loading on bench-press kinematics (peak velocity, peak acceleration and accelerative percentage of the concentric phase) and muscle activation (pectoralis major and anterior deltoid) in professional rugby and handball players. Seventeen professional athletes were randomly assigned to complete three separate bench-press repetitions with different AEL schemes (100/40%, 100/60% and 100/80% of 1RM eccentric/concentric loading, respectively) under two conditions: known- and unknown-concentric load (KL and UL, respectively). Results indicate that the lack of knowledge regarding the additional eccentric load induced a significant increase in peak acceleration and agonist-muscles electromyographic activity, with no changes regarding peak velocity or accelerative percentage during the concentric phase.

The aim of the study was to analyse the effects of 6 week (15 sessions) flywheel resistance training with eccentric-overload (FRTEO) on different functional and anatomical variables in professional handball players. Twenty-nine athletes were recruited and randomly divided into two groups. The experimental group (EXP, n = 15) carried out 15 sessions of FRTEO in the leg-press exercise, with 4 sets of 7 repetitions at a maximum-concentric effort.

Background: Human Malaria is transmitted by mosquitoes of the genus Anopheles. Transmission is a complex phenomenon involving biological and environmental factors of humans, parasites and mosquitoes. Among more than 500 anopheline species, only a few species from different branches of the mosquito evolutionary tree transmit malaria, suggesting that their vectorial capacity has evolved independently.

This study aimed to examine the relationship existing between maximum strength values in 2 common resistance training row exercises (bilateral bench pull [BBP] and one-arm cable row [OACR]) and short sprint performance in elite kayakers. Ten junior kayakers (5 women and 5 men) were tested on different days for 1 repetition maximum (1RM) and maximal voluntary isometric contraction in both exercises. Moreover, a 12-m sprint kayak was performed in a dew pond to record split times (2, 5, and 10 m), peak velocity, distance completed considering the first 8 strokes, and mean acceleration induced by right blade and left blade strokes.
