Authors: Kugele Anandi , Silkenath Bjarne , Langer Jakob , Wittmann Valentin , Drescher Malte
Published: April 2019

EPR spectroscopy of diamagnetic bio-macromolecules is based on site-directed spin labeling (SDSL). Here, we present a novel labeling strategy for proteins. We developed and synthesized a nitroxide-based spin label that can be ligated to proteins by an inverse-electron-demand Diels-Alder (DAinv) cycloaddition to genetically encoded non-canonical amino acids (ncAA). The nitroxide moiety is shielded by a photoremovable protecting group (PPG) with an attached tetraethylene glycol unit to achieve water solubility. We demonstrate SDSL of two model proteins with the PaNDA (Photoactivatable Nitroxide for DAinv reaction) label. Our strategy features high reaction rates combined with high selectivity, as well as high stability of the nitroxide in E. coli lysate.

Цель исследования. На основании разработанной в клинике нейросетевой модели «Экспертная система прогноза операционного риска» уточнить показания, ведение пред- и постоперационного периода и доказать эффективность выполнения симультанных оперативных вмешательств и мультивисцеральных резекций у пациентов с раком ободочной и прямой кишки.Материал и методы. В клинике общей хирургии ДонНМУ им. М. Горького на базе проктологического отделения ДоКТМО за период с 2012 по 2017 гг. проведено оперативное лечение 1394 пациентам с патологией толстой кишки. 1162 (83,3%) больных оперированы в клинике по поводу рака прямой и ободочной кишки. Из них 159 (13,6%) пациентам, имеющим сочетанную абдоминальную патологию, выполнены симультанные оперативные вмешательства; 183(15,7%) пациентам произведены мультивисцеральные резекции.Результаты. После лапаротомии, ревизии органов брюшной полости, оперативное лечение начинали с более чистого этапа, после этого выполняли основной этап хирургического вмешательства по поводу патологии толстой кишки.Заключение. Несмотря на продолжительность, объём оперативного вмешательства мы считаем, что выполнение симультанных оперативных вмешательств и мультивисцеральных резекций является оптимальным и оправданным, поскольку количество осложнений и функциональные результаты лечения больных в этой группе достоверно не отличается от группы больных со стандартными оперативными вмешательствами.

Published: April 2019

College students' physical education plays an important role in physical activity and cultivates the concept of independent health management. At present, what kind of learning attitude do Taiwan college students face in physical education? What motivation does the student influence the attitude of the physical education? What is the relevance? All of the above are the purpose of this study. The research method adopts the questionnaire survey method, and the survey data adopts descriptive statistical analysis, independent sample t test, single factor variance analysis, LSD post hoc comparison method, and typical correlation analysis. Research results: 1. The different background variables of Taiwanese college students are that the main motivation factor of physical education is to obtain good health fitness for "physical health". 2. Taiwanese college students have different background variables. They all think that the "cognitive learning" of physical education is the main factor of attitude, that is, the knowledge about health care and sports skills. 3. There is a positive correlation between learning motivation and learning attitude (ρ=.90). Learning motivation is one of the important factors affecting learning attitude. Research conclusions: 1. The factors of Taiwanese male and female college students' motivation for learning in physical education are mainly based on "physical health". 2. Freshmen have higher motivations and learning attitudes in physical education than second-grade to fourth-grade. 3. Taiwan female college students average 1 or 2 times per week, male college students have the most athletes 2 to 3 times per week, more than 90% of college students like sports. 4. There is a positive correlation between learning motivation and learning attitude, indicating that the stronger the attribute of learning motivation "physical health", the higher the student's learning attitude. 5. Satisfying students' motivation for learning helps students to learn positively. 6. Another important task of the college physical education class is to prepare students for future lifelong sports.

Characterizing Steady-State Cardiovascular and Metabolic Responses of Recreational Climbers During Motorized Treadmill Climbing
Authors: Heil Daniel Paul
Published: April 2019

Given that the popularity of indoor climbing exceeds that of outdoor climbing, health professionals need a better understanding of how these indoor climbing activities can be used to prescribe exercise. The primary goal of this study was to characterize both cardiovascular and metabolic responses of motorized treadmill climbing with respect to thresholds for heart rate as a percent of maximum (%HR) and metabolic equivalents (METs). Additionally, this study used these data to generate MET and energy expenditure (EE) prediction equations for prescription purposes. Methods: Twenty non-competitive recreational climbers (16 men; 4 women) were recruited to climb six combinations of “slow” and “fast” climbing speed (4.6-9.1 m/min) across three treadmill grades: vertical (90°), overhang or negative incline (85-80°), positive incline (95-100°). A portable metabolic system was worn by climbers during testing to measure HR and oxygen uptake (VO2), the latter of which was converted to EE and METs using standard formulae. Mean HR% and MET values were compared to intensity thresholds (65%, or 3 and 6 METs) using one-sample t-tests, while standard multiple regression techniques were used to predict EE and METs from a pool of variables (climbing treadmill speed and grade, body mass, gender. Results: HR% (70.0-85.4%) was >65% at all test conditions (P<0.01) and mean MET values exceeded the 3-MET threshold and was ≥6-MET threshold at all conditions (6.0-8.5 METs; P<0.01). Multiple prediction equations for both EE (R2=0.81; SEE=±0.83 kcals/min; P<0.001) and METs (R2=0.73; SEE=±0.6 METs; P<0.001) included speed, grade, and gender. Conclusions: The vigorous metabolic intensity for motorized treadmill climbing (≥6 METs) in this study was clearly sufficient to promote positive health and metabolic fitness in healthy adults. In addition, health professionals can use the EE and MET prediction equations to prescribe specific motorized treadmill climbing intensities to clients, as well as generate climbing-specific testing protocols.

Authors: Bodell Nathaniel Glen , Gillum Trevor
Published: April 2019

There is an increased instance of circulating triglycerides among older adults which could lead to atherosclerosis; therefore, we sought to determine if 30 minutes of moderate-intensity exercise, prior to a high fat meal, attenuates postprandial triglycerides (PPT) in postmenopausal women. Five postmenopausal women (59.8 years), participated in an exercise trial consisting of 30 minutes of moderate-intensity exercise 60% heart rate reserve (HRR), heart rate, blood pressure, and blood lipids collected. Following exercise participants ingested a high-fat meal (62 grams CHO, and 57 grams fat) and rested for four hours. Lipid levels were collected at 1, 2, 3, and 4 hours post-feeding. The control trial did not exercise and were given the high fat meal followed by rest. A randomized cross-over design was utilized, in which all subjects participated in the control and exercise trial. There was no difference in PPT between the control and exercise trials. PPT increased from pre-exercise in both trials (p<0.05) (pre-feeding 88.4±26.7 con. 93.6±36.8 ex., 1hr 141±51.7 con. 139±65.4 ex., 2hrs 195±32.7 con. 166±82.4 ex., 3hrs 203±52.2 con. 185±78.1 ex., 4hrs 179±22.4 con. 193±50.5 ex).

ABSTRACTThe pottery in Takalar regency, South Sulawesi province, has been existed for hundreds of years and has become part of a community cultural life. The study aims to identify the changes ofvarious ceramic forms and design from 1981 to 2010. This periodisation is chosen because in the 1980s the Department of Industry and Trade had supervised craftsmen in Takalar, which has given significant changes in the development of ceramics in the area. The method employed is a qualitative method with a multidisciplinary approach, including history and ethnography. To analysis the data, the research uses interactive techniques (Miles dan Hubermen, 1992). The research site covers three districts: Sandi, Pabbatangan, and Pakalli. The study shows there are significant changes in ceramic forms and design from 1980 to 2010. Based on the classification used, the changes are divided into three periods: traditional forms (1981-1990), transition forms (1991-2000), and modern forms (2001-2000). These changes are caused by the open attitude of the craftsman to outside agencies, such as Disperindag (government), universities, and consumers. These outside parties have influenced artisans to develop ceramic designs by introducing new shapes and values, including foreign cultures.Keywords: ceramic development, design and form changes, and craftsmentABSTRAKKeberadaan keramik di Kabupaten Takalar, Sulawesi Selatan, telah berlangsung selama ratusan tahun dan menjadi bagian kehidupan sosial budaya masyarakatnya.

Published: April 2019

The study aims at describing  (1) critical thinking of FIKT students (field independent with high category) students, (2) critical thinking of FDKT (field dependent with high category) students, (3) critical thinking of FIKS (field independent with medium category) students and (4) critical thinking of FDKS (field dependent with medium category) students. This study was descriptive study by employing qualitative approach. The research subjects were 4 students of class A1  of the second semester of Mathematics Education Study Program at UNM which categorized based on cognitive style by using the instrument of Group Embedded Figures Test (GEFT) and counting the IPK (Grade Point average) of mathematics courses on the first semester by differentiating two categories, namely high and medium categories, consisted of 2 field independent with high-medium category students and 2 field dependent with high-medium category students. Methods in collecting the data was critical thinking test, namely problem solving test of linear aquation systems and interviews. This study employed triangulation by comparing the data obtained through problem solving tests and interview. The result of critical thinking through problem solving was categorized based on critical thinking stage, namely clarification, analysis and solution strategy. The results of the study reveal that at the clarification stage,  the FIKT subject and FIKS subject had similarity in reading the questions briefly, understood  it directly and identifying the instructions of the questions; whereas, FDKT subject and FDKS subject read the questions repeatedly and only read instruction of the questions. At the Analysis stage,  FIKT subject and FIKS subject tended to be quick in abstracting and releting relevant information with supporting instruction of the questions, so it was quicker in concluding the method used to solve the problem. However, FDKT subject and FDKS subject tended to be longer in giving response,  so the method used was trial and error. At the solution Strategy, FIKT subject and FIKS subject applied the method used clearly and systematically; however, FIKS subject did mistake when determining k score using determinant (for the second question), unlike FDKT subject and FDKS subject which had difficulty when making conclusions based on question instruction and FDKS subject was also made mistake when determining  k score using determinant.

Karbon monooksid (CO, dəm qazı) metanın yanması nəticəsində yaranan iysiz, dadsız, rəngsiz, qıcıqlandırıcı xüsusiyyətləri olmayan qazdır. Adətən CO-nun atmosferdə konsentrasiyası 0,001 faizdən aşağı olur, lakin şəhər ərazilərində və ya qapalı mühitlərdə bundan yüksək ola bilər. Oksigenlə müqayisədə CO hemoqlobinlə daha möhkəm birləşərək, karboksihemoqlobin əmələ gətirir (COHb), nəticədə oksigenin nəqli və sərfinin zəifləməsi baş verir. CO həmçinin iltihab kaskadını sürətləndirir, bunun hesabına MSS-də lipidlərin peroksidləşməsi və gecikmiş nevroloji fəsadlara səbəb olur.

Yanğınla əlaqədar tüstü ilə nəfəs alma karbon monooksid (CO) zəhərlənmələrinin əsas hissəsini təşkil edir. Ehtiyatsızlıqdan, yanğınla əlaqəli olmayan CO zəhərlənmələri il ərzində təxminən 5-10 ölümə səbəb olur, ölümlə nəticələnən qəsdən törədilmiş CO zəhərlənmələrin sayı isə bundan iki dəfə artıqdır. Qəsdən törədilən  zəhərlənmələr üçün ölüm göstəricisi ehtiyatsızlıq üzündən baş verən hadisələrlə müqayisədə yüksəkdir.

Qəsdən zəhərlənmələrdən fərqli olaraq, ehtiyatsızlıqdan baş verən zəhərlənmələr həm mövsümi, həm də regional variasiyalar nümayiş etdirir və daha çox soyuq iqlim şəraitində qış aylarında baş verir. Əsasən gecikmiş neyrokoqnitiv pozğunluqlarla özünü göstərən xəstəlik vəziyyəti, ilkin stabilləşmədən sonra zərərçəkənlərin 40 faizə qədərində persistə edir.

Beta vulgaris or beet root contained high pigment of betalains that are used as food colorants and food additives due to their health promoting properties. The extraction of natural colorant compound from beet root under chemical- based extraction was identified as an alternative source of commercial synthetic colorant. Beet root is generally processed before consumption which influences the stability of betalains as well as affects the acceptability and health properties. Therefore, this study aimed to investigate the antioxidant activities of betalain-containing extracts and the influence of UV irradiation and heat on the betalain pigment at different concentrations, temperature and period of time. The impact of these factors was evaluated with spectrophotometric absorbance value on the basis of betalain chromaticity. The results of the DPPH antioxidant test revealed that the scavenging activity of betalain increasing proportional to its concentration and the highest 50% inhibition activity was recorded at 77.48%. At 3.0 g/l betalain concentration, the highest chromaticity value was recorded whereas temperature between 10 to 30°C was the most stable betalain pigment against heat stress. However continuous exposure of betalain pigment towards UV irradiation was found to cause discoloration of the samples.

The adulteration of butter has become a major problem in food industries. Butter has the similar characteristic to lard which makes lard a desirable adulterant in butter due to economic advantages. Therefore, the method of detection to analyse the adulteration practice must be developed. This study used NMR spectroscopy in combination with chemometrics for the authentication of butter from lard. The presence of lard as an adulterant in butter has been analysed using Gas Chromatography–Mass Spectrometry (GC-MS) and Nuclear Magnetic Resonance (NMR) spectroscopy with the aid of chemometric of Principal Component Analysis (PCA) and Discriminant Analysis (DA). PC1 described 82% of the variation while PC2 accounted for 15% of the variation resulted in a model that described 80% of the total variance in the data. With 82% of the peak variation along the first PC, it was clear that all seventeen samples of butter in the market and pure lard sample were formed according to their own group and showed two well-defined and well-separated group. DA model classified 100% of all samples accurately according to its group (butter and butter adulterated with animal fats), meaning that no samples were misclassified into the wrong group. Lard was successfully determined at 2.63 ppm. In this study, NMR and PCA analysis has successfully discriminated between the market sample and lard and the results established that there is no lard being adulterated in all commercial butter samples. This could be a potential identification approach to determine if the product has been deceived in market.

This article discusses the morphological changes in the structures of the lungs when adapting to some extreme factors and environmental conditions.One of the most pressing problems of biology is the elucidation of the mechanisms of adaptation of the human body and animals to changing environmental conditions [1-7]. This problem can be viewed in two aspects: firstly, in terms of the emergence of adaptive rearrangements in the body when exposed to environmental factors as a manifestation of the body's plasticity in ontogenesis, secondly, in terms of the emergence of adaptation, as genetically and phenotypically fixed adaptation of living organisms to the conditions environment, which arose in the course of evolution [8-13]. The key point here is the identification and comparison of subtle mechanisms of similar (to the same environmental factor) adaptation that arise in ontogenesis and formed in phylogenesis [14-21].

Es una investigación exploratoria, descriptiva y cualitativa, en la que se emplea la estratificación ya existente en Bogotá y que hace referencia a los niveles socioeconómicos (utilizando los estratos más altos, 5 y 6) aplicándola a varones y mujeres mayores de 40 años que estuvieran trabajando.

It is exploratory, descriptive and mainly qualitative. A survey was handed to a pre-established socio-economical stratified sample of Bogota’s upper class population (5-6), men and women who were 40 years or older, and working. Results indicate that for men and women, household work plays an important role in balancing W-F. They also show a rise in men’s involvement with domestic chores, with gender still being a determinant factor of who assumes responsibility.Keywords: work, family, harmonizing, domestic, Colombia

RESUMENLa internacionalización de las empresas se basa en el desarrollo de ventajas de propiedad, de localización y de internalización, esgrimida por Dunning a través del paradigma OLI. Las empresas latinoamericanas no han sido capaces de desarrollar suficientes ventajas y en su mayoría permanecen ancladas a la etapa de exportación. En comparación, las multinacionales chinas muestran una expansión vertiginosa. En este trabajo se analizan las estrategias utilizadas por ellas, para la generación de conocimientos, que las han llevado a tener uno de los procesos de expansión más dinámicos entre los países emergentes.Palabras clave: empresas multinacionales chinas, China, Latinoamérica, conocimiento. The knowledge generation in Chinese multinationalsABSTRACTThe internationalization of enterprises is based on development of advantages of ownership, location and internalization, wielded by Dunning through the OLI paradigm.
