ABSTRACT Introduction: Exercise can invigorate the body's metabolism. There are very few people who know how sports promote people's physical and mental health. How to lead people to participate in physical exercise through sports is a question worth considering. Objective: We explore the effects of sports on human metabolism. Methods: The article analyzes athletes’ physical and chemical indicators before and after exercise and during the recovery period. The indicators cover blood routine, urine routine, and blood testosterone content. Results: The blood and urine routines of athletes before and after training are different (P<0.05). After an expressive number of exercises, the urine testosterone content will be different due to the difference in genders (P<0.05). Conclusions: Physical exercise has a very significant impact on human metabolism. The body's hormone levels and metabolism are related to the amount of exercise.

ABSTRACT The literature presents several instances of interaction between the nervous system (NS) and the immune system (IS). These interactions are promoted by several molecules, such as cytokines and hormones, with modulating action for both the NS and IS. In this sense, the two systems may influence each other: changes in behavior may be accompanied by alterations in the IS (e.g., immunosuppression) and immunological disorders, such as infections, may modulate behavior (e.g., anxiety and depression). Considering that chronic stress, in addition to affecting behavior, also modulates the IS and that there is evidence that moderate intensity physical exercise (PE) protects physical and mental health, the objective of this review is to explore the influence of moderate-intensity PE on behavior and immunity.

Ultrasonographic Appearance

Local treatment of Dupuytren’s contracture, either by collagenase or needle fasciotomy, allows disruption of the pathological cord during forced extension. The purpose of this study was to investigate the cord before and after both treatments by ultrasound. A total of 39 patients with a minimum of 20° contracture in the metacarpophalangeal joint were included and randomized to treatment with either collagenase (20 patients) or needle fasciotomy (19 patients). The distance between the distal and the proximal parts of the ruptured cord was measured by ultrasound and the difference in passive joint movement before and after treatment was measured with a goniomenter. There were no significant differences between the collagenase and needle fasciotomy groups in the size of the rupture or gain of mobility. Most cords treated with collagenase and subsequent forced extension had the same ultrasonographic appearance as cords disrupted mechanically by needle fasciotomy. Level of evidence: III

1. This paper describes the results of an experiment designed to examine the ability of cells in the kitten's visual cortex to regain functional binocular connections following exposure to a brief period of visual deprivation. 2. Normal 4-wk-old kittens were exposed to a total of 12 h of optically induced strabismus over a period of 2 days, and single-unit recordings made the following day indicated that the proportion of striate cortex cells with binocular receptive fields had decreased sharply as a result of this episode of strabismic vision. 3. When these kittens were revived and allowed to experience a recovery period of normal binocular vision lasting either 3 or 7 wk, cortical binocularity returned to a normal level. 4. Statistical analysis revealed that the difference in the level of binocularity observed before and after the period of binocular recovery was highly significant, and comparison of the results from kittens allowed only a 3-wk recovery period with those from kittens allowed a 7-wk period indicated that a similar level of recovery was obtained in each group. 5. Histological reconstruction of electrode penetrations indicated that the recovery of binocular receptive fields occurred uniformly across all cortical laminae. 6. These data are discussed in terms of the results from previous recovery experiments, the relationship between cortical binocularity and the ability to maintain binocular fixation, and the possibility that subliminal cortical input plays a role in the recovery of functional binocular cells.

ABSTRACT Roasting is one of the most complex coffee processing steps due to simultaneous transfers of heat and mass. During this process, beans lose mass because of fast physical and chemical changes that will set color and flavor of the commercial coffee beverage. Therefore, we aimed at assessing the kinetics of mass loss in commercially roasted coffee beans according to heating throughout the processing. For that, we used samples of 350-g Arabica coffee processed grains with water content of 0.1217 kga kg-1, in addition to a continuous roaster with firing gas. The roaster had initial temperatures of 285, 325, 345 and 380 °C, decreasing during the process up to 255, 285, 305 and 335 °C respectively. Mass loss was calculated by the difference between grain weight before and after roasting. We observed a linear variation directly dependent on roaster temperature. For each temperature during the process was obtained a constant mass loss rate, which was reported by the Arrhenius model with r2 above 0.98. In a roaster in non-isothermal conditions, the required activation energy to start the mass loss in a commercial coffee roasting index was 52.27 kJ mol -1.

Many factors affect the driving force of fungal growth and secretion. To compare the differences of Lasiodiplodia theobromae infected poplar wood, the changes of physical and chemical properties of vertically and horizontally infected poplar wood before and after dyeing were analyzed, and the infection characteristics were studied in this paper. The horizontal infection was more effective than the vertical infection in terms of infection depth, color depth, and microscopic hyphal invasion. The mycelium first intruded into the earlywood tissue and began to secrete a large amount of pigment after twenty days. The crystallinity of mycelium decreased slightly, and the difference in weight loss rate was negligible. The initial contact angle of the dyed specimen on the horizontal infection increased drastically in distilled water, but there was almost no difference between varnish and natural coating. The horizontal infection was more efficient than the vertical infection and had a higher color depth and a better induction effect, which is crucial in future microbial dyeing.

Abstract Background Calf augmentation can be achieved by fat grafting, calf implants, or a combination of both methods (composite augmentation). For safety reasons, it is important to be aware of important calf anatomic features, specific physiologic considerations, and some health conditions that can hinder the outcome of these procedures. Objectives The aim of this study was to present our experience with performing composite calf augmentation, and to describe indications, surgical techniques and safety issues. Methods We retrospectively analyzed 63 patients who had undergone composite calf augmentation for cosmetic and reconstructive surgery in our practice. We reviewed group demographics, complications, and results, and identified all the pitfalls encountered in our cases. Additionally, dissection of the calf regions in fresh cadavers was performed to obtain more accurate anatomy. We also measured intracompartmental pressures before and after calf augmentation with implants in 6 cases to determine pressure changes. Results All cases received subfascial implant insertion and fat grafting as a delayed procedure. If there is a need for multiple implants, we recommend a staged procedure. Our study showed high muscle sensitivity to pressure increase after augmentation. Hence, from the standpoint of safety, we advocate subcutaneous fat grafting only. No patients developed compartment syndrome. Conclusions Composite calf augmentation surgery is safe and easy to reproduce, with a short recovery period and a low complication rate when done as a staged procedure and respecting specific anatomic and physiologic calf features.

ABSTRACT Introduction: It is not unusual that students do not like physical education. It has become a common educational phenomenon in current school physical education. Students have become less participative in physical education, serious and cold, less enjoyable, and stressed. The emergence of this series of changes is not entirely a matter of student attitudes. Objective: Aiming at school students who like sports but do not fall in love with physical education, participation quality continues to decline, students do not exercise themselves, and have no concept of exercise load. This research aims to learn and master the knowledge and skills of physical exercise through a digital fitness teaching system, effectively improve students’ scientific exercise ability, mobilize students’ hobbies to actively participate in physical exercise, improve the unscientific physical exercise habits of students in the past, promote students’ physical and mental health, and lay the foundation for lifelong physical education. Methods: The methods studied in this article mainly include an experimental method, document method, expert interview method, questionnaire survey method, mathematical analysis method and other methods. Results: After two weeks of experimental preparation and ten weeks of teaching experiments to develop students’ physical exercise ability, the students’ aerobic exercise ability has been steadily improved. Through the digital fitness teaching system, students’ interest in participating in physical exercise is strengthened and the cultivation of sports emotions and physical habits, improving the school's physical exercise environment and meeting students’ physical exercise needs. Conclusions: The digital fitness teaching system is in the development and test stage. The first generation of digital fitness bikes has many problems with hardware and software. As an important supplementary form of school physical education under the new situation, this system greatly promotes students’ lifelong physical education and learning scientific physical exercise.

Rapid thermal annealing (RTA) of ion-implanted Si is important for device fabrication. The defect structures of 2.5, 4.0, and 6.0 MeV As-implanted silicon irradiated to fluences of 2E14, 4E14, and 6E14, respectively, have been analyzed by electron diffraction both before and after RTA at 1100°C for 10 seconds. At such high fluences and energies the implanted As ions change the Si from crystalline to amorphous. Three distinct amorphous regions emerge due to the three implantation energies used (Fig. 1). The amorphous regions are separated from each other by crystalline Si (marked L1, L2, and L3 in Fig. 1) which contains a high concentration of small defect clusters. The small defect clusters were similar to what had been determined earlier as being amorphous zones since their contrast was principally of the structure-factor type that arises due to the difference in extinction distance between the matrix and damage regions.
