    Masalah dalam penelitian ini yaitu rendahnya hasil belajar pendidikan jasmani Olahraga dan kesehatan siswa SD Negeri 16 Sintoga Kec.Sintuk Toboh Gadang Kabupaten Padang Pariaman. Penelitian ini bertujuan untuk mengetahui hubungan motivasi Olahraga dan kemampuan motorik dengan hasil belajar pendidikan jasmani olahraga dan kesehatan siswa SD Negeri 16 Sintoga Kec. Sintuk Toboh Gadang Kabupaten Padang Pariaman. Jenis penelitian ini adalah korelasional. Populasi dalam penelitian ini yaitu siswa di SD Negeri 16 Sintoga Kec. Sintuk Toboh Gadang Kabupaten Padang Pariaman yaitu berjumlah sebanyak 77 orang, terdiri dari kelas IV yang berjumlah sebanyak 39 orang dan kelas V berjumlah sebanyak 38 orang. Teknik pengambilan sampel menggunakan purposive sampling. Dengan demikian jumlah sampel di dalam penelitian ini adalah sebanyak 36 orang. Data motivasi olahraga di peroleh dari hasil penyebaran angket kepada siswa yang terpilih menjadi sampel, variabel kemampuan motorik di peroleh dari hasil pengukuran terhadap kemampuan motorik siswa dan data hasil belajar penjas orkes di peroleh dari nilai siswa yang tertera di dalam rapor. Data dianalisis dengan korelasi productmoment dan dilanjutkan dengan korelasi ganda. Berdasarkanhasilanalisis data menunjukkan bahwa motivasi olahraga mempunyai hubungan secara signifikan, karena ditemukanrhitung 0,341>rtabel 0,329 danthitung = 2,11>ttabel1,69 . Variabel kemampuan motorik mempunyai hubungan secara signifikan karena ditemukan rhitung 0,402 >rtabel 0,329 danthitung = 2,56> t tabel 1,69 Sedangkan variabel motivasi olahraga dan kemampuan motorik secara bersama-sama mempunyai hubungan secara signifikan dengan hasil belajar pendidikan jasmani olahraga dan kesehatan dan diterima kebenarannya secara empiris,  karena ditemukan  rhitung = 0,487> rtabel 0,329  dan Fhitung = 5,13> Ftabel 3,29

    The aim of the study was to investigate the microbiota in the cervical part of the teeth in the gingival margin of the oral cavity of rats at the end of the second, fourth and sixth weeks of the experimental action of the opioid analgesic nalbuphine. Under the action of opioids for six weeks, changes in the microbiocenosis in the studied subbiotope of the oral cavity of animals were found, which manifested themselves in the early stages by the appearance of gram-negative anaerobes, gradual increase in opportunistic pathogens, formation of dental biofilm experiment.The aim of the study was to investigate the microbiota in the cervical part of the teeth in the gingival margin of the oral cavity of rats at the end of the second, fourth and sixth weeks of the experimental action of the opioid analgesic nalbuphine.

    The aim of the study was to examine the periodontal tissues of white rats under two weeks of opioid exposure, after its abolition and drug correction for four weeks at the optical level. After two weeks of experimental action of the opioid analgesic and its subsequent four-week withdrawal, pronounced irreversible changes in the structural components of the periodontium of animals were not detected, however, and their complete recovery was not observed. The proposed drug correction with pentoxifylline and ceftriaxone with opioid withdrawal after two weeks of its administration, led to the restoration of microcirculation and trophic tissues of periodontal tissues of rats, their morphological organization was approaching normal.The aim of the study was to examine the periodontal tissues of white rats under two weeks of opioid exposure, after its abolition and drug correction for four weeks at the optical level.

    Desarrollo, subjetividad y transgresiones identitarias en las costas del sur- austral chileno

    This work is part of an investigation into the contemporary dynamics of development and modernization in the southern and far southern coastal areas of Chile, specifically the shoreline of the northern part of the Aysen Region. The objective is to propose a theoretical-conceptual reflection to enable ethnographic data to be framed as a problem and interpreted as a function of a political reading which - why not say so? - could transform the world of the southern and far southern coastal zone. The central argument of the text is hypothetical: the dilemmas of development, in the current circumstances of the coasts of the Aysen Region, are susceptible of resolution (at least up to a point) from a conscious, reflexive change of perspective on culture as the word is understood in anthropology. Este trabajo se enmarca en una investigación sobre las dinámicas contemporáneas del desarrollo y la modernización en las costas sur-australes de Chile, específicamente en el litoral norte de la región de Aisén. A partir de un conjunto de datos etnográficos se propone una reflexión teórico-conceptual que permita problematizar e interpretar esos datos en función de una lectura política y, por qué no decirlo, transformadora del mundo costero sur-austral. El argumento central del texto tiene carácter hipotético: las encrucijadas del desarrollo, en las actuales coyunturas de las costas aiseninas, son susceptibles de ser resueltas (al menos hasta cierto punto) a partir de un giro reflexivo y consciente sobre eso que en antropología llamamos cultura

    Hypoglycemia and the Origin of Hypoxia-Induced Reduction in Human Fetal Growth

    The most well known reproductive consequence of residence at high altitude (HA >2700 m) is reduction in fetal growth. Reduced fetoplacental oxygenation is an underlying cause of pregnancy pathologies, including intrauterine growth restriction and preeclampsia, which are more common at HA. Therefore, altitude is a natural experimental model to study the etiology of pregnancy pathophysiologies. We have shown that the proximate cause of decreased fetal growth is not reduced oxygen availability, delivery, or consumption. We therefore asked whether glucose, the primary substrate for fetal growth, might be decreased and/or whether altered fetoplacental glucose metabolism might account for reduced fetal growth at HA.Doppler and ultrasound were used to measure maternal uterine and fetal umbilical blood flows in 69 and 58 residents of 400 vs 3600 m. Arterial and venous blood samples from mother and fetus were collected at elective cesarean delivery and analyzed for glucose, lactate and insulin. Maternal delivery and fetal uptakes for oxygen and glucose were calculated.The maternal arterial – venous glucose concentration difference was greater at HA. However, umbilical venous and arterial glucose concentrations were markedly decreased, resulting in lower glucose delivery at 3600 m. Fetal glucose consumption was reduced by >28%, but strongly correlated with glucose delivery, highlighting the relevance of glucose concentration to fetal uptake. At altitude, fetal lactate levels were increased, insulin concentrations decreased, and the expression of GLUT1 glucose transporter protein in the placental basal membrane was reduced.Our results support that preferential anaerobic consumption of glucose by the placenta at high altitude spares oxygen for fetal use, but limits glucose availability for fetal growth. Thus reduced fetal growth at high altitude is associated with fetal hypoglycemia, hypoinsulinemia and a trend towards lactacidemia. Our data support that placentally-mediated reduction in glucose transport is an initiating factor for reduced fetal growth under conditions of chronic hypoxemia
