A Study on the Effects of Chinese Massage on Physical and Mental Health in Participants Based Smart Healthcare

The purpose of this study is to understand the influence of the effect of the smart Chinese massage appliance on the participants’ sports performance and physical and mental health after intermittent exercises. The study was performed by a mixed-study method. First, the experimental research method was used to design an experimental procedure and specifications such as data collection scope. Next, the quantitative research was carried out, using SPSS 26.0 statistical software to analyze data from the questionnaire. Then, the qualitative research was carried out by interviewing experts and respondents and obtaining their opinions. Finally, all the data were collated and analyzed using the multidimensional review method. Findings. Chinese massage significantly improved the physical fitness, exercise performance, body composition, and physical and mental health status of high-strength cyclic exercise participants. High-strength exercises can improve the physical and mental health of men. Medium-strength exercises could improve current conditions for women. Oxygen intake remained peaked for 8 sessions for men and increased after 30 sessions for women. Both groups required a 1-2-week adaptation period but had different exercise performance periods. After the experiment, head and back pain, as well as stress and negative emotions, was improved. The high intensity of the exercises relieved fear, headache or head stress, overeating, and other problems.

Microcirculatory and Metabolic Responses during Voluntary Cycle Ergometer Exercise with a Whole-Body Neuromuscular Electrical Stimulation Device

Vigorous exercise increases blood viscosity and may pose a risk of cardiovascular events in patients with cardiovascular diseases. We recently reported that single-use of novel whole-body neuromuscular electrical stimulation (WB-NMES) can be safely applied in healthy subjects without adversely affecting blood fluidity. We performed a crossover study to explore the effectiveness and safety of a hybrid exercise with ergo-bicycle and WB-NMES; 15 healthy volunteers, aged 23–41 years, participated in this study. No arrhythmias were detected during the hybrid exercise and 20 min recovery, and although blood fluidity was transiently exacerbated immediately after both the exercise programs, in vivo parameters in the sublingual and nailfold microcirculation remained unchanged. There was a significant decrease in blood glucose and increase in lactic acid levels immediately after both exercise programs. Even with the same workload as the cycle ergometer exercise, the oxygen intake during the hybrid exercise remained higher than that during the cycle ergometer exercise alone (p < 0.05, r = 0.79, power = 0.81). Both the hybrid and voluntary cycle ergometer exercises transiently exacerbated blood fluidity ex vivo; however, microvascular flow was not adversely affected in vivo.

Selective laser melting of Al and AlSi10Mg: parameter study and creep experiments

Selective laser melted (SLM) aluminum alloys are widely used for many technical applications. However, the application is limited to low temperatures due to their relatively poor creep resistance. The creep resistance and strength could be enhanced by oxide dispersion-strengthening. A hypothesis is that oxygen intake during selective laser melting can lead to formation of fine aluminum oxides and thus strengthen the SLMed part. To elucidate this in more detail, selective laser melted AlSi10Mg was tested in creep experiments at temperatures of 300 °C. Although, in other studies at lower temperatures, a relatively large stress exponent for creep was found, the high temperatures in this work led to a creep exponent of just 7 to 8, indicating no significant dispersion strengthening. Furthermore, for future research, it was necessary to investigate the feasibility of SLM with pure aluminum. For this purpose, a parameter study was carried out and an optimum parameter set for pure aluminum was found. Dense samples with a porosity below 0.2% were produced. Selective laser melting was carried out with a varying oxygen content in the inert-gas atmosphere to elucidate the hypothetic strengthening effects by oxygen intake. However, even at 800 ppm oxygen in the atmosphere, no effect on hardness and microstructure could be observed.

The possibilities of the highlands in optimizing the condition of athletes

The objective of the research is to study the influence of restorative motor mode at the high altitude on functional condition of the sportsmen body during their stay in the mountains and the subsequent readaptation period. Materials and methods. Ten male sportsmen, whose specialization was medium and long-distance running took part in the research. The research was conducted in Bishkek during the 3-week stay in highlands (2350 m) and after their return to the foothills. During their stay in the mountains the sportsmen followed a specific motional mode in the form of outdoor activities. At the high altitude (2nd, 7th, 12th and 22nd days) and during the readaptation period (5th–6th and 18th–19st days) the condition of the respiratory function, cardio respiratory system and the maximum level of oxygen intake of sportsmen were evaluated. Results. During their stay in the mountains the increase of external expiration reserves and optimization of cardiovascular activity were observed. The level of maximum oxygen consumption after a decrease increased during the period of readaptation by 9,8% (P < 0,05). Conclusions. Outdoor activities at the high altitude conditions allow you to preserve and expand the functional reserves of the body of sportsmen during the transient period of the oneyear training macrocycle.

Utilizing the wood waste for eco-friendly mixed-media artwork

Wood waste can be found easily around us. It is usually used as household fuel resulting burning smoke that pollutes the air and reduces oxygen intake, later it would have a contribution to climate change. As alternative, to reduce air pollution due to wood waste combustion, it can be use as part of media artwork. This study used action research to create mixed-media artwork by utilizing the wood waste to reduce wood waste from industry. The results of this study are expected to help maintain eco-friendly industry and reduce the impact of climate change.

ANALISIS HASIL PEMERIKSAAN FISIK DAN LABORATORIUM DEMAM BERDARAH DENGUE DERAJAT I DAN II DI RSUD H. SAHUDIN KUTACANE TAHUN 2021

Dengue fever is a severe fever that is often deadly, caused by a virus, characterized by capillary permeability, hemostasis abnormalities and in severe cases, shock syndrome loss of protein. The disease is divided into several degrees. To ensure patients suffer from DENGUE disease, it is necessary to perform physical and laboratory examinations such as hematology tests. This study aims to analyze the results of physical examinations and laboratories of DBD degrees I and II at H.Sahudin Kutacane Hospital. The study used descriptive methods with a Cross Sectional approach. Accidental sampling and the number of samples obtained is 20 respondents, among others, degrees I and II are 10 respondents. The data collection tool is carried out using observation sheets including demographic data, physical examination of DBD degrees I and II, and normal standard numbers and laboratory examination units of Amanah Kutacane Clinic. The results of research conducted from a physical examination of DBD degrees I and II show signs and symptoms of DENGUD disease that appear differently because in addition to the condition of a person's body response is different, It may also be because it has been given symptomatic and supportive treatment, while the laboratory results of DBD degrees I and II are only platelets whose value is low from normal numbers (150,000-450,000/μl) of 88,500/μl and 42,300/μl respectively and these laboratory results are affected by adequate fluid and oxygen intake and nutritious food intake so as to support proper administration of action/management

Transcriptome Analysis Provides Insights into Hepatic Responses to Trichloroisocyanuric Acid Exposure in Goldfish (Carassius auratus)

In this study, goldfish (Carassius auratus) were exposed to 0 (control group) and 0.81 mg/L TCCA for four consecutive days. The liver transcriptome, the molecular indices of oxidative stress, and gills histopathology were investigated. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that energy metabolism-related pathways such as glycolysis/gluconeogenesis were significantly enriched, suggesting their perturbation in the liver of goldfish. Additionally, TCCA exposure also caused pathological damage in gills, which compromised physiological function and decreased oxygen intake capacity of gills, thus leading to the enhancement of anaerobic metabolism. This finding was confirmed by the significant upregulation of lactate dehydrogenase in the liver of goldfish. Moreover, many phase I and phase II metabolic enzymes might be activated to alleviate TCCA-induced toxicity in goldfish, and glutathione S-transferases (GSTs) and cytochrome P450s (CYPs) play a crucial role in the metabolism of TCCA in the liver of goldfish. Furthermore, the antioxidant enzyme analysis showed that TCCA exposure induced oxidative damage in the liver and partially impaired the antioxidant defense system of goldfish, evidenced by decreased superoxide dismutase (SOD) and catalase (CAT), and increased malondialdehyde (MDA) level. In summary, this study will improve our understanding of the molecular mechanisms of the TCCA-induced toxicity in goldfish.

POINT: Is it Time to Rethink Aerobic Exercise Prescription Methods?

ABSTRACT Exercise prescription is complex and can vary greatly. As well, methods have their own advantages and disadvantages. The purpose of this discussion is to consider if some of these methods should be modified. We look at the concept of the heart rate and oxygen intake reserve because it is recommended by the American College of Sports Medicine.

INTERMITTENT HYPOXIC THERAPY IN THE TREATMENT OF BRONCHIAL ASTHMA PATIENTS WITH VARIOUS CHRONOTYPES

The purpose of the paper is to identify the efficacy of normobaric interval hypoxic therapy in the treatment and rehabilitation of bronchial asthma patients, taking into account their individual characteristics of circadian rhythms. Materials and Methods. The authors examined the indicators of the functional respiratory system and oxygen regimes of the body, lipid peroxidation and antioxidant system and spirometric data in 145 patients with bronchial asthma. Patients’ chronotypes were also determined. Bronchodilators were used to carry out individual peak flowmetry and to determine airway sensitivity, which made it possible to reveal the bronchial tree reactivity. In order to identify individual intolerance to the hypoxic factor and to select the optimal oxygen level in the gas mixture all patients underwent a hypoxic test before the hypoxic therapy. Results. The results obtained showed that morning hypoxic therapy sessions had the greatest effect in patients with bronchial asthma. A decrease in the malondialdehyde level indicated a decrease in lipid and protein peroxidation. An increase in the blood glutathione peroxidase and superoxide dismutase rates showed an increase in antioxidant protection. Intermittent normobaric hypoxic therapy improved the body oxygen supply during its transport and contributed to oxygen intake and a hypoxic decrease in the bronchopulmonary system. The hypoxic mixture was chosen individually, taking into account patient’s chronotype, in order to induce the subcompensated hypoxia. However, the morning hours turned out to be optimal for the greatest mobilization of compensatory mechanisms and adaptation to hypoxia in most patients. Conclusion. We consider it necessary to adjust recommendations for the use of intermittent normobaric hypoxic therapy in bronchial asthma patients, taking into account their circadian rhythms, and to recommend conducting hypoxic therapy in the morning and in the afternoon (from 8 a.m. to 3 p.m.). Keywords: bronchial asthma, intermittent hypoxytherapy, chronotypes, functional respiratory system, prooxidant and antioxidant systems. Цель – определение эффективности использования нормобарической интервальной гипокситерапии в лечении и реабилитации пациентов с бронхиальной астмой с учетом индивидуальных особенностей суточных ритмов. Материалы и методы. У 145 пациентов с бронхиальной астмой анализировались показатели функциональной системы дыхания и кислородных режимов организма, перекисного окисления липидов и антиоксидантной системы, спирометрические данные; определялись хронотипы больных. С помощью пробы с бронходилятатором проводилась индивидуальная пикфлоуметрия и определялась чувствительность дыхательных путей, что позволило выявить степень реактивности бронхиального дерева. Перед гипокситерапией всем больным проводился гипоксический тест с целью выявления индивидуальной непереносимости гипоксического фактора и подбора оптимального содержания кислорода в газовой смеси. Результаты. Полученные результаты показали, что наибольшим эффектом обладают утренние сеансы гипокситерапии. Понижение уровня малонового диальдегида явилось показателем снижения перекисного окисления липидов и белков. Рост уровня глютатионпероксидазы и супероксиддисмутазы в крови свидетельствовал об усилении антиоксидантной защиты. Интервальная нормобарическая гипокситерапия улучшила обеспечение организма кислородом на этапах его транспортировки и способствовала повышению потребления кислорода тканями, а также снижению степени гипоксии в бронхолегочной системе. Несмотря на то, что гипоксическая смесь подбиралась пациентам индивидуально с учетом их хронотипов и с целью вызвать развитие субкомпенсированной гипоксии, оптимальными для наибольшей мобилизации компенсаторных механизмов и адаптации к гипоксии оказались утренние часы. Выводы. Считаем необходимым внести коррективы в рекомендации по использованию интервальной нормобарической гипокситерапии у пациентов с бронхиальной астмой с учетом суточных ритмов и рекомендовать проведение курсов гипокситерапии в утренние и дневные часы – в промежутке с 8 до 15 ч. Ключевые слова: бронхиальная астма, интервальная гипокситерапия, хронотипы, функциональная система дыхания, прооксидантная и антиоксидантная системы.
