Background: Breastfeeding is a dynamic process in which the infant recruits several muscle groups in his face, head and throat.
Objective: The objective of this study was to explore the relative role of the submental muscle group, the orbicularis oris and the sternocleidomastoid muscles to breastfeeding process and to the relatively high intra-oral vacuum measured during this process.
Methods: Electromyography (EMG) measurements were conducted on 11 infants (mean age 1.91 ± 1.0 days, mean weight 3364 ± 328 g) using surface electrodes. The EMG data were filtered with a low pass filter to yield the linear envelopes (IEMG). The maximal and mean value and the area under each linear envelope curve were examined.
Results: During active suckling significantly higher activity (P< 0.05) of the submental muscle group were measured compared with the orbicularis oris and sternocleidomastoid muscles (mean ± SE values of the maximal linear envelope were 24.4 ± 1 μV, 9.6 ± 0.6 μV and 14 ± 0.7 μV, respectively).
Conclusion: These results confirmed that jaw movements have the primary role during breastfeeding, but also revealed that the inspiratory muscles have a substantial contribution to this process and probably have an important role in the generation of intra oral vacuum measured during breastfeeding.

Lead (Pb) is an environmental toxin ubiquitously present in the human environment due to anthropogenic activities and industrialization. Lead can enter the human body through various sources and pathways, such as inhalation, ingestion and dermal contact, leading to detrimental health effects. The majority of lead that enters the body is removed by urine or feces; however, under chronic exposure conditions, lead is not efficient, as lead is absorbed and transferred to numerous organs, such as the brain, liver, kidney, muscles, and heart, and it is ultimately stored in mineralizing tissues such as bones and teeth.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airway inflammation, airflow limitation, reduced health-related quality of life (HRQL), and exercise intolerance. Pulmonary rehabilitation (PR) is essential for COPD management, but outcomes may be influenced by individual physiological factors. Cardiopulmonary exercise testing (CPET) measures oxygen pulse (O2P), an indicator of stroke volume, yet the impact of baseline O2P on PR effectiveness remains unclear.

Background: This study investigated the acute effects of inspiratory muscle warm-up (IWU) on vocal performance in singers. Proper vocal and respiratory warm-up can enhance vocal range, quality, and endurance. The aim was to determine whether IWU improves maximum phonation time and pitch range, contributing to better voice production efficiency (vocal efficiency) and reduced fatigue.

Beta - stimulant, that is, β - adrenergic stimulant, also known as β - agonists, is bioactive catecholamine compounds naturally produced in animals' adrenal medulla glands that induce relaxation in asthmatic airway smooth muscles upon inhalation while also temporarily boosting athletic alertness and alleviating fatigue. However, their potential for dependency poses health risks including unnoticed exacerbation leading to severe illness or fatality prompting their inclusion on WADA's prohibited substances list. Surface - enhanced Raman spectroscopy (SERS) offers a rapid, sensitive, and label - free means for identifying characteristic peaks associated with β - agonist compounds.

Background: Inspiratory and expiratory muscle training (RMT) has been shown to have beneficial effects in individuals with long-term post-COVID-19 symptoms.
Objective: To assess the effects of adding RMT to an aerobic exercise (AE) training program for health-related quality of life (HRQoL) and exercise tolerance in individuals with long-term post-COVID-19 symptoms, and to evaluate the effects on physical and lung function, and psychological status.
Methods: 64 individuals with long-term post-COVID-19 symptoms of fatigue and dyspnoea were randomly assigned to AE+RMT or AE+RMT groups for an 8-wk intervention (AE: 50min/day, 2 times/wk; RMT: 40min/day, 3 times/wk).
