The purpose of this study was to analyze the effect wool in patients with chronic obstructive pulmonary disease. The study was conducted experimentally on 53 patients with chronic obstructive pulmonary disease attending the chest diseases polyclinic of a hospital located in Erzurum. A randomized selection method was used to categorize patients into two groups; a treatment (n = 27), and a control group (n = 26). Patients in the treatment group (pre-test measurements were taken) wore wool vests for a period of three months, while patients in the control group wore cotton vests (placebo) for the same duration; post-test measurements were taken for both groups at the end of the three-month period. The Medical Outcomes Study Short Form 36, the St. George's Respiratory Questionnaire, and pulmonary function tests were used to collect data. Results concluded that there was a significant decrease (p < 0.05) in the overall score of the St. George's Respiratory Questionnaire, and the symptom, effect, and activity mean scores, while there was a significant increase (p < 0.05) in the SF-36 physical functioning, general health, bodily pain, role physical, vitality, role emotional, social functioning, mental health, physical and mental component summary mean scores of patients in the treatment group. Results of the study concluded that the symptoms, activity, disease effectiveness, and quality of life improved in patients that wore wool vests.

In the complex insulation system that is used in extra high voltage(EHV) devices, according to the trend for electric power equipment of high capacity and reduction of its size, macro interfaces between two different bulk materials which affect the stability of insulation system exist inevitably. In this paper, the dielectric strength decrease of the macro interfaces between epoxy and ethylene propylene diene terpolymer(EPDM) was estimated by using the applied voltage to breakdown time characteristics. Firstly, the AC short time dielectric strength of specimens was measured at room temperature. Then, the breakdown time was measured under the applied constant voltage which is 70% of short time breakdown voltage. With these processes, the life exponent n was determined by inverse power law, and the long time breakdown voltage can be evaluated. The best condition of the interface was LOS(low viscosity(350 cSt) silicone oil spread specimen). When 30 years last on the specimens, the breakdown voltage was estimated 44% of the short time breakdown voltage.

Objectives: Eight Constitution Medicine (ECM) categorizes individuals into eight constitutions based on physiological differences in organ relations and recommends different diets for different constitutions. This study presents a preliminary analysis of the effect of following constitutional food regimens on quality of life and health outcomes for different constitutions. Methods: This cross-sectional, comparative study used subjects recruited from Essen University Hospital Traditional Chinese Medicine Center in Germany. From a convenience sample of 243 Germans, those in the groups Hepatonia/Cholecystonia (n = 95) and Pulmotonia/Colonotonia (n = 26) were analyzed for health outcomes in relation to their dietary habits of either including or avoiding meat. Health outcomes were measured with SF-36, self-reported survey. Results: The two groups had no significant differences in the health outcomes of SF-36. However, subjects in Hepatonia/Cholecystonia who had followed their dietary habit for more than 20 years had significantly better scores on general health, social functioning, mental health, emotional role functioning, and mental component scores than those in Pulmotonia/Colonotonia, regardless of their meat intake. Conclusions: This study established initial groundwork for considering patients' constitutions when evaluating health outcomes and their relation to diet. Further studies are warranted on the effects of regulating food intake according to individual constitution.

Dogs exhibit patterns of health issues that vary by life stage. An understanding of disease incidence with respect to breed and age/life stage could be an important component of canine health management and welfare. This study aimed to describe the age-specific disease incidence of 3 small dog breeds that attended veterinary clinics in the Republic of Korea, based on data from electronic veterinary medical records (EVMRs). A total of 40,785 EVMRs from Maltese (n = 21,355), Miniature Poodle (n = 11,658) and Shih Tzu dogs (n = 7,772) were analyzed. Common health problems in 3 small dog breeds were 'diseases of the skin' and 'diseases of the ear,' respectively. Among dogs aged ≤ 3 years, 'preventive medicine' was the most common cause cited for veterinary clinic visits. Among dogs aged 4 to 8 years, the most frequent health problems were 'diseases of the skin.' Among dogs aged 9 to 13 years, 'heart diseases,' 'kidney diseases,' 'mammary gland tumor,' and 'neoplasia (unspecified)' were considerably more frequent, compared to the rates in dogs ≤3 years. Among dogs aged ≥ 14 years, 'heart diseases' and 'sneezing/cough' were the main health problems. In all breeds, the frequencies of 'diseases of circulatory system,' 'diseases of respiratory system,' 'diseases of the nervous system,' 'endocrine' and 'neoplasia' increased rapidly with aging. This surveillance could inform strategies for disease screening tests and management based on life stage in these dog breeds and enable more effective health management.

The transportation is almost dependent on a single fuel petroleum with transportation energy dilemma. Hybrid Electric Vehicle(HEV) technology holds more advantages on efficiency improvements for petroleum consumption at the transportation. And bearing is recognized as the important component of gearbox. Gearboxes for HEV transmission have been ensured the highest reliability over some years in withstanding high dynamic loads. At the same time, the demands of lightweight design and cost minimization are required by thought-out design, high-quality material, superior production quality and maintenance. In order to design a reliable and lightweight gearbox, it is necessary to analyze bearing rating life methods between standard and different bearing companies with calculation methods for modification factors. In this paper, the influence of life time of bearings will be pointed out. Bearing contact stress and load stress distribution of HEV gearbox are obtained and compared with Romaxdesigner and BearinX. And the unequal wear of the left bearing for the gearbox intermediate shaft is investigated between simulation and test.

Double-stranded RNA (dsRNA) induces gene silencing in a sequence-specific manner by a process known as RNA interference (RNAi). The RNA-induced silencing complex (RISC) is a multi-subunit ribonucleoprotein complex that plays a key role in RNAi. VIG (Vasa intronic gene) has been identified as a component of Drosophila RISC; however, the role VIG plays in regulating RNAi is poorly understood. Here, we examined the spatial and temporal expression patterns of VIG-1, the C. elegans ortholog of Drosophila VIG, using a vig-1::gfp fusion construct. This construct contains the 908-bp region immediately upstream of vig-1 gene translation initiation site. Analysis by confocal microscopy demonstrated GFP-VIG-1 expression in a number of tissues including the pharynx, body wall muscle, hypodermis, intestine, reproductive system, and nervous system at the larval and adult stages. Furthermore, western blot analysis showed that VIG-1 is present in each developmental stage examined. To investigate regulatory sequences for vig-1 gene expression, we generated constructs containing deletions in the upstream region. It was determined that the GFP expression pattern of a deletion construct (${\Delta}-908$ to -597) was generally similar to that of the non-deletion construct. In contrast, removal of a larger segment (${\Delta}-908$ to -191) resulted in the loss of GFP expression in most cell types. Collectively, these results indicate that the 406-bp upstream region (-596 to -191) contains essential regulatory sequences required for VIG-1 expression.

INI1/hSNF5/BAF47 is a core component of the hSWI/ SNF ATP-dependent chromatin remodeling complex, and it has been implicated in regulating gene expression, cell division and tumorigenesis. We investigated whether INI1/hSNF5/BAF47 functions in activation of the colony stimulating factor 1 (CSF1) promoter in HeLa cells. Overexpression of INI1/hSNF5/BAF47 promoted CSF1 transcription, and siRNA targeting INI1/hSNF5/ BAF47 (siINI1) strongly inhibited the activity of the CSF1 promoter. We demonstrated that all conserved domains of INI1/hSNF5/BAF47 are needed for CSF1 transcription. ChIP experiment showed that INI1/ hSNF5/BAF47 is recruited to the region of the CSF1 promoter. Taken together, these results indicate that INI1/hSNF5/BAF47 is involved in activation of the CSF1 promoter.

Sensor nodes are the most significant part of a wireless sensor network that offers a powerful combination of sensing, processing, and communication. One major challenge while designing a sensor node is power consumption, as sensor nodes are generally battery-operated. In this study, we proposed the design of a low-power, long range-based wireless sensor node with flexibility, a compact size, and energy efficiency. Furthermore, we improved power performance by adopting an efficient hardware design and proper component selection. The Nano Power Timer Integrated Circuit is used for power management, as it consumes nanoamps of current, resulting in improved battery life. The proposed design achieves an off-time current of 38.17309 nA, which is tiny compared with the design discussed in the existing literature. Battery life is estimated for spreading factors (SFs), ranging from SF7 to SF12. The achieved battery life is 2.54 years for SF12 and 3.94 years for SF7. We present the analysis of current consumption and battery life. Sensor data, received signal strength indicator, and signal-to-noise ratio are visualized using the ThingSpeak network.
