Effects of different types of exercise on sleep quality based on Pittsburgh Sleep Quality Index in middle-aged and older adults: a network meta-analysis.

A 2021 survey by the World Health Organization showed that 27% of the global population experiences sleep problems and that middle-aged and older adults are more likely to have sleep disorders. Sleep deprivation increases cardiovascular disease risk. This study aimed to assess the effects of aerobic exercise, resistance exercise, combined training, and yoga on the quality of sleep in middle-aged and older adults through their effects on the Pittsburgh Sleep Quality Index (PSQI) and its components. Direct and indirect comparisons were used to determine which exercise modality most effectively improves sleep quality in middle-aged and older adults. This study conducted a systematic review and frequency network meta-analysis of all randomized controlled trials comparing the effects of aerobic exercise, resistance exercise, combined training, and yoga with a control group on sleep quality in middle-aged and older adults. We included 28 studies involving 3,460 participants. According to the surface under the cumulative ranking (SUCRA) curve results, aerobic exercise was the most effective in improving total PSQI score (SUCRA = 93.2%), sleep latency (SUCRA = 96.8%), and sleep medication use (SUCRA = 77.1%). In addition, yoga was the most effective in improving sleep disorders (SUCRA = 90.4%), sleep efficiency (SUCRA = 95.9%), sleep duration (SUCRA = 93.8%), and daytime dysfunction (SUCRA = 98.3%). Aerobic exercise is the most effective exercise modality for improving PSQI total score in middle-aged and older adults. Registry: PROSPERO; Identifier: CRD42023454237.

Characteristics of 2D Ultrasonic Vibration Incremental Forming of a 1060 Aluminum Alloy Sheet.

Currently, 1060 aluminum alloy is widely applied in the electronics industry, construction, the aerospace field, traffic engineering, decorations, and the consumer goods market for its good chemical, physical, and mechanical properties. In general, excellent processing property is necessary and important for the manufacturing of complicated panels. In this paper, a special 2D ultrasonic vibration incremental forming method is designed to improve its plasticity and mechanical properties. Three kind of processing methods, including traditional single-point incremental forming, longitudinal ultrasonic vibration incremental forming, and 2D ultrasonic vibration incremental forming, are used for the flexible manufacturing of cones and cylindrical cups of 1060 aluminum alloy sheet. Then, micro-hardness tests, residual stress tests, and scanning electron microscopy tests are carried out to probe the changes in micro-structure and mechanical properties and to analyze the effects of different types of ultrasonic vibration on the plasticity and fracture characteristic of 1060 aluminum alloy. It is proven that 2D ultrasonic vibration facilitates the improvement of plasticity and surface qualities of 1060 aluminum alloy better than the other two processing methods. Therefore, the novel 2D ultrasonic vibration incremental forming process possesses substantial application value for the flexible and rapid manufacturing of complicated thin-walled component of aluminum alloy.

The right job pays: Effects of different types of work on study progress of pre-service teachers

Teacher shortages are a significant concern in many countries. Hiring pre-service teachers could help to alleviate this problem while providing students an opportunity to develop skills in a real-work context. However, being employed alongside full-time studying might compete with attendance or self-study and, thereby, hinder study progress. This study analyzed the effect of student employment on the study progress of 132 pre-service teachers, using 25 repeated measures over 4 years (n = 3,245). Employment hours, remuneration, domain-relevance, and timing (year of college) were taken into account. Multilevel growth analyses showed that students who spent more time on a paid teaching job in year 3 or 4 obtained significantly more study credits compared to those who were not paid or got paid for a job outside of education. Overall, student employment did not relate to less study progress and depending on domain-relevance, timing and remuneration, the effect can even be positive.

Effects of different types of dried fruit on sensory and texture properties of white cheese

In the study, five kinds of white cheese produced, one of which was a control sample (CC). According to the amount of curd used in the production of cheese, black mulberry (C1), blackberry (C2), black grape (C3) and raspberry (C4) dried fruit added to the curd at a rate of 2%. The cheeses packed with a vacuum packaging machine and left to ripening for 90 days at 7±1°C. During the ripening period (3rd, 30th, 60th, 90th days) samples were taken from cheeses, sensory analyses were performed, and textural parameters including resilience, hardness, springiness, gumminess, cohesiveness, adhesiveness, and chewiness were determined using texture profile analyses (TPA). It was observed that neither cohesiveness, adhesiveness and springiness parameters of texture profile differed in terms of cheese type, nor important statistical difference was identified (p˃0.05), differences regarding the ripening process found out though (p<0.05).

Molecular simulation of different types of polysilsesquioxane doped cellulose insulating paper: A guide for special cellulose insulating paper

To develop special insulating paper is of great significance to promote the service life of transformers. Using molecular simulation to guide the development of special insulating paper can greatly reduce the trial-and-error rate and waste of resources in traditional experiments. The effect of different types of polysilsesquioxane (POSS) on cellulose insulating paper was investigated by using molecular simulation. This paper investigated the thermal stability and mechanical properties and electrical characteristics of caged POSS, semi-caged POSS, and ladder-like POSS doped cellulose insulating paper. The results show that POSS with all types can enhance the performance of cellulose insulating paper, and ladder-like POSS possess the best modification effect. The glass transition temperature was increased by 58 K, and the bulk modulus, shear modulus, and elastic modulus of cellulose insulating paper doped with ladder-like POSS can improve up to 27.07%, 45.67%, and 41.28%, respectively. Meanwhile, the dielectric properties of ladder-like POSS modified insulating paper are also significantly improved. The findings of this paper propose a method for the preparation of ladder-like POSS modified insulating paper, which provides theoretical guidance for the experimental preparation of special insulating paper.

Effects of Different Types of Music on Students’ Study Efficiency

Music has been omnipresent in people’s daily lives; therefore, it is crucial to evaluate how it exerts influence as people depend more on it. Many studies suggest that listening to background music has a positive impact and raises study efficiency, while others suggest that it is counterproductive because it negatively impacts attention levels. These equivocal results occur because people focus on different tasks while testing the effect of background music. This paper explores various effects on students’ study efficiency of three genres of background music, classical music, white noise or environmental sounds, and lyrical pop music. Classical music had both beneficial and harmful impacts depending on different cognitive tasks. White noise, surprisingly, has some positive impact on students, especially for ADHD students. Lyrical music has a generally distracting effect on study tasks. Certainly, more research about how three types of music impact students is needed. Since music has become more and more entrenched in people’s life, this paper hopes to provide insight into how three types of music can be incorporated into tasks that helps performance and avoid using those that might hurt students’ performance.

Barriers to Exercise in Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease: A Patient Survey.

Although adequate physical activity is an essential component of treatment for metabolic dysfunction-associated steatotic liver disease (MASLD), the majority of people with MASLD do not engage in regular exercise and lead sedentary lifestyles. We aimed to identify perceived barriers to exercise and to examine awareness about the role of exercise in the treatment of MASLD. Individuals aged 18 years and above were recruited from a hepatology outpatient clinic. MASLD severity was assessed using controlled attenuation parameter (CAP) and transient elastography (TE) determined liver stiffness measurement (LSM) for the severity of hepatic steatosis and fibrosis, respectively. An online questionnaire was administered to record self-reported exercise patterns, barriers to exercise, and knowledge regarding effectiveness of different types of exercise for MASLD. Eighty-one participants (57% female) with a mean age of 55.3 ± 13.4 years and a mean body mass index (BMI) of 33.8 ± 6.4 answered the questionnaire. The mean CAP score was 335.7 ± 47.8 dB/m, and the median LSM was 12.45 kPa. While most patients (83%) considered MASLD to be a serious health concern, 73% did not achieve the recommended exercise levels of ≥ 150 min of moderate-intensity physical activity per week, and 54% were unsure about the role of exercise in the treatment of MASLD. Commonly reported barriers to exercise included physical and mental health issues (57%), lack of time (43%), lack of enjoyment in exercising (31%), fatigue caused by exercise (24%), and others (25%). Most participants with MASLD were unaware of the role of exercise as a potential treatment option and were not achieving recommended exercise levels. Inadequate time, physical and mental health problems, lack of enjoyment in exercise, and fatigue were major barriers.

Bacterial community shifts occur primarily through rhizosphere expansion in response to subsoil amendments.

To comprehensively evaluate the impact of agricultural management practices on soil productivity, it is imperative to conduct a thorough analysis of soil bacterial ecology. Deep-banding nutrient-rich amendments is a soil management practice that aims to improve plant growth and soil structure by addressing the plant-growth constraints posed by dense-clay subsoils. However, the response of bacterial communities to deep-banded amendments has not been thoroughly studied. To address this knowledge gap, we conducted a controlled-environment column experiment to examine the effects of different types of soil amendments (poultry litter, wheat straw + chemical fertiliser and chemical fertiliser alone) on bacterial taxonomic composition in simulated dense-clay subsoils. We evaluated the bacterial taxonomic and ecological group composition in soils beside and below the amendment using 16S rRNA amplicon sequencing and robust statistical methods. Our results indicate that deep-banded amendments alter bacterial communities through direct and indirect mechanisms. All amendments directly facilitated a shift in bacterial communities in the absence of growing wheat. However, a combination of amendments with growing wheat led to a more pronounced bacterial community shift which was distinct from and eclipsed the direct impact of the amendments and plants alone. This indirect mechanism was evidenced to be mediated primarily by plant growth and hypothesised to result from an enhancement in wheat root distribution, density and rhizodeposition changes. Therefore, we propose that subsoil amendments regardless of type facilitated an expansion in the rhizosphere which engineered a substantial plant-mediated bacterial community response within the simulated dense-clay subsoils. Overall, our findings highlight the importance of considering the complex and synergistic interactions between soil physicochemical properties, plant growth and bacterial communities when assessing agricultural management strategies for improving soil and plant productivity.

Evolution of Impaired Renal Function in Children After Continent Vesicostomy

Abstract The aim of this study was to determine whether early commencement of clean intermittent catheterisation can improve impaired kidney function in children with continent vesicostomy as well as to analyse the effect of different types of continent vesicostomy and the observed outcome. All children with continent urinary derivation performed at the University Children’s Hospital in Belgrade, Serbia, during the period 1990-2016, were included in this retrospective-prospective study. The participants were divided into three groups with respect to type of continent vesicostomy (appendicovesicostomy, preputial continent vesicostomy, and vesicostomy using distal ureter). Clean Intermittent Catheterisation with continent vesicostomy, oxybutynin, and antibiotic prophylaxis were used in a standard way. Renal function was monitored by the value of glomerular filtration rate taken before the start of the therapy and three years afterward. The significance of differences was tested by the paired-samples t-test and ANOVA test. We analysed 74 patients aged 3 to 10 years (5.5-y average) of which 80% were boys. Renal function improved in 60.5% patients. A highly significant improvement in kidney function three years after the commencement of combined treatment was shown irrespective of the performed method of vesicostomy (p<0.01). Using the ANOVA test, we have proved that there is no difference in the efficiency of therapy between particular groups (p= 0,256). The timely started therapy lead to significant kidney function improvement. The type of continent vesicostomy did not affect kidney function.

Primary alcohols as killers of Ni-based catalysts in transfer hydrogenation

The effect of different types of alcohols used as hydrogen donors on the activity of a metal Ni-based catalyst in the hydrogenation of benzofuran as a model substrate under transfer hydrogenation conditions has been studied. The hydrogenation process of benzofuran using 2-PrOH as a hydrogen donor leads sequentially to dearomatization and then to deoxygenation of the substrates. At the same time, the use of primary alcohols such as MeOH, EtOH and 1-PrOH as hydrogen donors leads to irreversible deactivation of the Ni-containing catalyst. A clear mechanism of deactivation of Ni-based metal catalysts by primary alcohols has been established. The interaction of the catalyst with primary alcohols at a temperature of 250 °C leads to the formation of an inactive Ni3C carbide phase, as well as sintering and segregation of metal particles on the surface of the alumina support.

Non-pharmacological interventions on quality of life in stroke survivors: A systematic review and meta-analysis.

Non-pharmacological interventions have been used in the rehabilitation of stroke survivors, but their effects on stroke survivors' quality of life (QoL) are unknown. This review aimed to summarize the existing evidence regarding non-pharmacological interventions for QoL in stroke survivors and to evaluate the effectiveness of different types of interventions. We systematically searched databases including PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chinese BioMedical Literature Database, China Science and Technology Journal Database, and Wanfang data from the earliest available records to March 2023. Randomized controlled trials which explored the effects of non-pharmacological interventions on QoL in stroke patients were included. The meta-analysis was conducted to evaluate the effectiveness of different interventions on QoL. The Review Manager 5.3 was used to conduct the meta-analysis and the revised Cochrane risk-of-bias tool was used to assess the methodological quality of trials. A total of 93,245 records were identified, and 34 articles were reviewed and summarized, of which 20 articles were included in the meta-analysis. The summary of the findings of the included studies revealed fitness training, constraint-induced movement therapy (CIMT), physical exercise, music therapy (MT), and art-based interventions may have positive effects on QoL. The fitness training improved total QoL, especially in physical domains including physical functioning (mean difference [MD] = 10.90; 95% CI [7.20, 14.59]), role physical (MD = 10.63; 95% CI [6.71, 14.55]), and global health (MD = 8.76; 95% CI [5.14, 12.38]). The CIMT had a slight effect on general QoL (standardized mean difference [SMD] = 0.48, 95% CI [0.16, 0.80]), whereas significantly improved strength (MD = 8.84; 95% CI [1.31, 16.38]), activities of daily living/instrumental activities of daily living (ADL/IADL; MD = 10.42; 95% CI [2.98, 17.87]), and mobility (MD = 8.02; 95% CI [1.21, 14.83]). MT had a positive effect on the mental health domain (SMD = 0.54; 95% CI [0.14, 0.94]). Our findings suggest that fitness training and CIMThave a significant effect on improving physical QoL, while MThas a positive effect on improving psychological QoL. Future studies may use comprehensive and multicomponent interventions to simultaneously improve the patients' physical, psychological, and social QoL.

Trends in the Incorporation of Antiseptics into Natural Polymer-Based Nanofibrous Mats.

Nanofibrous materials represent a very promising form of advanced carrier systems that can be used industrially, especially in regenerative medicine as highly functional bandages, or advanced wound dressings. By incorporation of antimicrobial additives directly into the structure of the nanofiber carrier, the functionality of the layer is upgraded, depending on the final requirement-bactericidal, bacteriostatic, antiseptic, or a generally antimicrobial effect. Such highly functional nanofibrous layers can be prepared mostly by electrospinning technology from both synthetic and natural polymers. The presence of a natural polymer in the composition is very advantageous. Especially in medical applications where, due to the presence of the material close to the human body, the healing process is more efficient and without the occurrence of an unwanted inflammatory response. However, converting natural polymers into nanofibrous form, with a homogeneously distributed and stable additive, is a great challenge. Thus, a combination of natural and synthetic materials is often used. This review clearly summarizes the issue of the incorporation and effectiveness of different types of antimicrobial substances, such as nanoparticles, antibiotics, common antiseptics, or substances of natural origin, into electrospun nanofibrous layers made of mostly natural polymer materials. A section describing the problematic aspects of antimicrobial polymers is also included.

Applications of Hydrocolloids and Its Effects on Physicochemical Characteristics of Gluten-free Bread from Corn and Rice Flour

Rice and corn flour can be used for gluten-free bread using a number of food hydrocolloids to improve the physicochemical properties closer to wheat products. This research aims to observe the effect of different types of food hydrocolloids, namely xanthan gum, glucomannan, carrageenan and CMC (Carboxymethyl Cellulose) on the physicochemical characteristics of gluten-free bread made from rice and corn flour. This research used a completely randomized design with two replications. This research observed the application of hydrocolloids to the formulation of gluten-free bread. The optimal increase in hydrocolloid concentration was determined to be 1 g for both CMC and carrageenan in both corn and rice flour. The highest addition of 1 g CMC in gluten-free bread made from corn flour, resulted in a specific volume of 3.422 cm3/g. The best gluten-free corn bread after drying contains a composition of 5.73% moisture content, 1.89% ash content, 17.34% fat content, 9.37% protein content, 65.67% carbohydrate content, and energy of 456.22 Kcal.

Examination of Hippotherapy’s Effect on Balance and Mobility in Children with Cerebral Palsy

Cerebral Palsy is caused by abnormal brain development or damage to the developing brain that affects a person’s ability to control his or her muscles. People with Cerebral Palsy often have balance and mobility problems associated with their diagnosis. Because a common symptom is stiff muscles, physical therapy is a common way to help decrease spasticity (CDC). Hippotherapy is an alternative form of therapy that has been gaining popularity. This treatment aims to help patients gain the necessary muscles needed to walk and perform daily activities while riding a horse. When riding a horse, a person must make adjustments each time the horse takes a step, which is beneficial for patients who need to learn balance skills. This review explores the effects of different types of Hippotherapy on patients with different types of Cerebral Palsy. The results of several research papers suggest that Hippotherapy does have an impact on patients’ overall balance and motor skills after a series of therapy sessions.

The potential anti-tumor effect of anesthetics on cancer by regulating autophagy.

Autophagy is a conserved, cellular self-degradation system that is essential for maintaining intracellular homeostasis. Increasing evidence suggests that autophagy plays an important dual regulatory role in the development of many human diseases, such as cancer. Recent studies have shown that the autophagy process in tumor cells can be regulated by various stimuli from both intracellular and extracellular environments, including the effects of anesthesia. Anesthetics have been shown to not only have clinical anesthetic and sedative effects but also play important roles in the progression of tumors. The effects of different types of anesthetics on tumors differ. In this review, we summarize the basic information on autophagy, the regulatory function of autophagy in cancer, currently used autophagy-targeted tumor therapy, and the effects of different types of anesthetics on tumor progression. We focus on the molecular mechanisms by which anesthetics exert tumor-inhibiting effects by activating or inhibiting autophagy. Herein, we also explore the potential application of the anesthetic/autophagy system in clinical tumor treatment. These findings provide a theoretical basis for the use of anesthetics during the perioperative period to suppress tumor development and provide insights for autophagy-targeted cancer treatment and drug development.

Вплив паління на цитогенетичний статус слизової оболонки ротової порожнини в осіб підліткового та юнацького віку

Cytogenetic monitoring provides information on both the health status of the population under study and the impact of genotoxic factors, i.e., the cytogenetic status of a person can serve as a biomarker of the level of exposure to genotoxicants, including various types of smoking. Purpose - to investigate the effect of different types of smoking on the cytogenetic status, namely, to analyse the cariological parameters of buccal epithelial cells of the oral mucosa in teenagers and young adults. Materials and methods. The cytogenetic status was studied by analysing the karyological parameters of buccal epithelial cells of the oral mucosa in 114 adolescents aged 15 to 24 years, who were divided into groups: the Group I included 26 people who smoke traditional cigarettes; the Group II - 22 people who smoke electronic cigarettes (vapes); the Group III - 23 people who smoke tobacco heating devices (IQOS); the Group IV - 43 people without smoking habits. Results. A significant increase in epithelial cells of buccal epithelium with nuclear disorders was found in smokers compared to the group of people without smoking habits. In addition, in individuals without smoking habits, no nuclear disorders such as protrusions, proliferation rates, early stage of nucleus destruction and completion of nucleus destruction were detected. Conclusions. The sensitivity of buccal epithelial cells to the effects of different types of smoking was established, which affects changes in cariological parameters. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the author.

Insights into the role of defects on the Raman spectroscopy of carbon nanotube and biomass-derived carbon

Raman spectroscopy can effectively detect disorder in carbon materials through defect-activated peaks. However, distinguishing between different defect species in carbon using Raman spectroscopy is often challenging, leading to potentially misleading attributions, particularly in the case of carbon materials containing a significant number of amorphous components. In this study, we provide a comprehensive analysis of in-situ Raman spectra from commercially available carbon nanotubes (CNTs) with various defects during its annealing treatment process. Through the in-situ removal of different oxygen functional groups and H atoms during annealing treatment of CNTs, we track and discuss dynamic surface changes to unveil their impact on the Raman spectra. Furthermore, we examine the complex influence of amorphous components using biomass-derived carbon as a model for amorphous carbon, shedding light on their contributions to Raman spectra. We also consider Raman signals stemming from molecular vibrations in the same spectral regions. By thoroughly understanding the fundamental effects of different types of defects on the two specific carbon models, we try to give some inspirations for analyzing different carbon materials by Raman spectroscopy with high reliability and validity.

Effect of Different Natural Extenders in Maintaining the Quality of Sperm Fish (Cyprinus carpio)

High demand on as consume fish nor as decorative fish, causes an increasing production. But, an obstacle occurs on production, due to reproductive characteristic of Common Carp fish. Different time on sperm and eggs production from male and female fish cause difficulties in breeding. Hence, it needed sperm preservation so the breeding could be done in whole year. Natural extenders are the solution to preserve fish sperm without side effect. The purpose of this study was to determine the effect of different types of extenders and different doses on the percentage of sperm motility and viability of carp (Cyprinus carpio) after storage This research was conducted at the Faculty of Fisheries and Marine Sciences, Universitas Brawijaya and the Freshwater Cultivation Installation (IBAT Punten), Batu, East Java. The method in this study was Complete Random Design (CRD) with 6 treatments, K (100ml lactate ringer); A (1ml cider + 99ml lactate ringer); B (1ml coconut + 99ml lactate ringer); C (1ml date juice + 99ml lactate ringer); D (1ml honey + 99ml lactate ringer); E (1ml sugar cane + 99ml lactate ringer). The results showed that the highest motility was obtained in the treatment of using date extract extender with a motility percentage rate of 77.66%; highest viability was obtained in the honey extract with 80.71%; and the highest fertility rate was obtained in the honey extract treatment with 72.67 %.

Evidence of a Viable but Nonculturable (VBNC) Phase in B. abortus S19 under Oxidative Stress (H2O2, -Fe2+, Bleach) and under Non-Oxidative Inhibitory Conditions (Isopropanol, Erythritol, Selenite).

The effect of oxidative stress on the survival of various Brucella species has not been fully investigated yet. We here conducted a study in which we investigated the effect of different types of oxidative stress (Fe2+, H2O2, bleach) versus non-oxidative inhibitory effects (selenite, erythritol, and isopropanol) on the survival of B. abortus S19, B. abortus S19 ∆mglA 3.14, and B. neotomae 5K33. The work focuses on the appearance of ATP-CFU quotient imbalances indicating the existence of a viable but nonculturable (VBNC) form of B. abortus S19, as has previously been shown.

Effect of Carrier Materials for Active Silver in Antibacterial Powder Coatings

Environmentally friendly powder coatings which have the advantages of being VOC-free, low-cost, and high-efficiency with a high recovery rate have been attracting increasing research attention. The introduction of antibacterial agents into the powder coatings endows them with a capacity to kill bacteria and viruses on the surface of objects; additionally, this enables them to inhibit the indirect transmission of pathogenic microorganisms. Silver, possessing broad-spectrum, strong, and stable antibacterial properties, is considered to be a promising antibacterial material for use in coating applications. Carrier materials for active silver play an important role in its activity and stability. However, there is a lack of systematic studies on the effects of different types of carriers in such coating systems, especially in green powder coating systems. In this paper, we investigated two types of carriers for active silver agents: zeolite, i.e., Linde type A (LTA) zeolite and Y-type zeolite; clay-based materials, i.e., montmorillonite and vermiculite. All the agents showed high antibacterial activity, with antibacterial rates of over 99% as compared to commercial agents. Among the four agents, the Ag-LTA zeolite antimicrobial agent showed a reduction rate of over 99.99%; additionally, it maintained a reduction rate of 99% after seven washing cycles. Thus, this agent was demonstrated to have the highest effectiveness and high durability; these features can be attributed to the high silver content and small particle size. The LTA zeolite also provides a protective effect for silver ions, protecting them from reduction, due to the restriction of elemental silver formation within the confined interior space of the α-cage structure. The Y-type zeolite antimicrobial agent exhibited a slightly lower antimicrobial performance due to its higher silicon-to-aluminum ratio and its lower cation exchange capacity. Comparatively, antimicrobial agents utilizing clay-based carriers have lower cation exchange capacity, resulting in poorer antimicrobial effectiveness than zeolite carriers. In addition, silver loaded on clay-based materials is prone to detach from the carrier and undergo a reduction reaction, making the coating yellowish in color. This study first provides information on the roles of different types of carriers in powder coating systems; then, this information guides the selection of carriers for active silver for the development of efficient antimicrobial agents and coatings.
