DIFFERENTIAL INFLUENCE OF PERIPHERAL AND SYSTEMIC SEX STEROIDS ON SKELETAL MUSCLE QUALITY IN PRE- AND POSTMENOPAUSAL WOMEN.
2011
Aging is associated with gradual decline of skeletal muscle strength and mass often leading to diminished muscle quality. This phenomenon is known as sarcopenia and affects about 30% of the over 60-year-old population. Androgens act as anabolic agents regulating muscle mass and improving muscle performance. The role of female sex steroids as well as the ability of skeletal muscle tissue to locally produce sex steroids has been less extensively studied. We show that despite the extensive systemic deficit of sex steroid hormones in postmenopausal compared to premenopausal women, the hormone content of skeletal muscle does not follow the same trend. In contrast to the systemic levels, muscle t…
Effects of Upper Body Eccentric versus Concentric Strength Training and Detraining on Maximal Force, Muscle Activation, Hypertrophy and Serum Hormone…
2022
Effects of eccentric (ECC) versus concentric (CON) strength training of the upper body performed twice a week for 10 weeks followed by detraining for five weeks on maximal force, muscle activation, muscle mass and serum hormone concentrations were investigated in young women (n = 11 and n = 12). One-repetition bench press (1RM), maximal isometric force and surface electromyography (EMG) of triceps brachii (TB), anterior deltoid (AD) and pectoralis major (PM), cross-sectional area (CSA) of TB (Long (LoH) and Lateral Head (LaH)) and thickness of PM, as well as serum concentrations of free testosterone, cortisol, follicle-stimulating hormone, estradiol and sex hormone-binding globulin were mea…
Selected needling techniques in pain associated with musculoskeletal disorders: a narrative review
2022
Background: Therapies involving various needling techniques are becoming more common treatment methods for musculoskeletal disorders. Aim of the study: To review the most commonly used needling techniques and their effect on the level of pain and functional status of patients with selected musculoskeletal disorders, i.e., lower back pain, upper trapezius muscle (UT) pain, cervicogenic headaches, myofascial pain syndrome (MPS), and chronic pain localized to the knee joint. Material and methods: A review of the academic literature was conducted between December 2021 and January 2022. The needle therapy methods used in the treatment of pain ailments were selected based on publications availabl…
Enkephalin-containing interneurons are specialized to innervate other interneurons in the hippocampal CA1 region of the rat and guinea-pig
1998
Enkephalins are known to have a profound effect on hippocampal inhibition, but the possible endogenous source of these neuropeptides, and their relationship to inhibitory interneurons is still to be identified. In the present study we analysed the morphological characteristics of met-enkephalin-immunoreactive cells in the CA1 region of the rat and guinea-pig hippocampus, their coexistence with other neuronal markers and their target selectivity at the light and electron microscopic levels. Several interneurons in all subfields of the hippocampus were found to be immunoreactive for met-enkephalin. In the guinea-pig, fibres arising from immunoreactive interneurons were seen to form a plexus …

Decreasing muscle performance associated with increasing disease activity in patients with rheumatoid arthritis
2018
Objectives Increasing evidence suggests that inflammation has a detrimental effect on muscle strength. Our objective was to analyse the association between muscle performance and different disease activity levels in patients with rheumatoid arthritis (RA). Method A total of 199 consecutive outpatients were subject to cross-sectional assessment. Measurements of grip strength, endurance of the upper and lower limbs and trunk strength were combined as a muscle performance composite score (MPCS), using a standardised method. The disease activity for 28 joints (DAS28), radiographs of small joints (Larsen score), rheumatoid factor, body mass index (BMI), comorbidities and anti-rheumatic drugs wer…
It takes time to see the menu from the body: an experiment on stable isotope composition in freshwater crayfishes
2015
For many applications and ecological studies in which wild individuals are brought to laboratory it would be essential to know accurately how fast novel diet is reflected in composition of different tissues. To study the effects of two different diets on the stable isotope composition of freshwater crayfish muscle and hemolymph, we conducted a three month experiment on noble crayfish (Astacus astacus) and signal crayfish (Pacifastacus leniusculus) by feeding them sweet corn (Zea mays) or Baltic herring (Clupea harengus membras) as novel food. During the experiment, the crayfish were given 0.4 g of selected food daily and the amount consumed was recorded. The samples for the stable isotope a…
Carbohydrates consumption pre exercise attenuate bone resorption marker in young female gymnasts
2019
Purpose: Bone mineral density (BMD) is modified by environmental factors like diet, nutritional status and exercise. Athletes have higher bone turnover than sedentary individuals but prolonged exercise might result in a negative remodeling balance and compromise skeletal health. Strenuous exercise and fasting may induce osteoclastic activity that is not necessarily accompanied by a compensatory increase in osteoblastic activity. The purpose of this study was to understand if there is specific nutrition to allow best performance and reduce bone resorption that occurs after exercise in athletes. Methods: A group of 28 gymnasts aged between 9 and 14 years old (13 ± 1.71) playing artistic gymna…
Drug Induced Liver Injury (DILI) due to variability in monacolin K content in Red Yeast Rice (RYR): An expert opinion
2020
Abstract Introduction Red yeast rice (RYR) is an effective cholesterol-lowering nutraceutical reversibly inhibiting 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase. As liver damage is a possible (albeit rare) side effect of HMG-CoA inhibitors, it make sense to focus on the tolerability of the liver to RYR extracts. The aim of this paper is to offer an expert opinion on the risk of liver damage by the use of RYR extract. Methods A review of the available literature has been carried out and critically reviewed by the authors. Results According to a large meta-analysis of 53 randomized clinical trials comprising 112 treatment arms, which included 8535 subjects with 4437 in the RYR arm and …
