Glucose Availability

Intestinal cells harvested from wethers injected with phlorizin were utilized to determine the effects of decreased glucose availability on glucose, glutamine, and butyrate oxidation by ovine intestinal cells. Phlorizin injection increased (P = 0.002) conversion of substrates to CO2 by isolated enterocytes but not by colonocytes (P = 0.098). Key words: Enterocytes, colonocytes, ruminant, glucose

Glucose Availability

We examined whether hyperglycemia stimulates carbohydrate oxidation independent of insulin. Rates of total glucose disposal and substrate oxidation (indirect calorimetry) were measured at 4 insulin concentrations and at each level of insulin at 4 glucose concentrations in 88 separate studies in 22 normal volunteers. The insulin sensitivity of carbohydrate and lipid oxidation was independent of glycemia, but glucose, independent of insulin, increased the absolute rate of carbohydrate oxidation and decreased lipid oxidation. To compare the ability of glucose and insulin to stimulate carbohydrate oxidation, oxidation rates were examined at similar rates of total glucose disposal induced by hyperinsulinemia or hyperglycemia. At physiological matched rates of glucose disposal, insulin stimulated carbohydrate oxidation 2.4-fold more than glucose. The free fatty acids (FFA) were significantly lower in the presence of hyperinsulinemia than hyperglycemia. When compared at similar (supraphysiological) rates of total glucose disposal, where the FFA were completely suppressed, the rate of carbohydrate oxidation was related to the total rate of glucose disposal rather than the ambient glucose or insulin concentrations. We conclude that both glucose and insulin can increase carbohydrate oxidation in humans. We propose that the rate of carbohydrate oxidation is determined by FFA availability and by glucose availability independent of the FFA level in glucose-consuming tissues. Although FFA availability is almost solely determined by insulin, both glucose and insulin can increase carbohydrate oxidation by increasing glucose availability.

Middle Piece

Energy for sperm motility is provided by both glycolytic and respiratory pathways. Mitochondria are involved in the latter pathway and conserve energy of substrate oxidation by coupling to phosphorylation. During spermatogenesis, the mitochondria undergo extensive transformation which in many species leads to the formation of a nebemkem. The nebemkem subsequently forms into a helix around the axial filament complex in the middle piece of spermatozoa.Immature spermatozoa of axolotls contain numerous small spherical mitochondria which are randomly distributed throughout the cytoplasm (Fig. 1). As maturation progresses, the mitochondria appear to migrate to the middle piece region where they become tightly packed to form a crystalline-like sheath. The cytoplasm in this region is no longer abundant (Fig. 2) and the plasma membrane is now closely apposed to the outside of the mitochondrial layer.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract (1%). These tumors express the CD 117 in 95% of cases. The stomach is the preferential localization (70%). Diagnosis is difficult and sometimes late. Progress of imaging has greatly improved the management and the prognosis. Computed tomography (CT) is the gold standard for diagnosis, staging, and treatment follow-up. The increasing recognition of GIST’s histopathology and the prolonged survival revealed some suggestive imaging aspects. Key words: gastro-intestinal stromal tumors; computed tomography; diagnosis

This article aims at describing the obseroance of wasiat wajibah (compulsory bequeathment) in the Islamic court of Banten, analyzing the provision of the substitute heir and adopted children in the Compilation of  Islamic Law (KHI). In addition, the ideal laws to manage the innheritance rules in Indonesia. This article is library research by using doctrinal approach and using case study and survey methods. The data was, then, analyzed by using analytical descriptive and analytical correlative methods. The result showed that the observance of wasiat wajibah in the Islamic court of  Banten employed by judges is by using the Mawali Hazairin’s Doctrine. The criteria of the adoption of substitute heir and adopted children in the KHI is the attempts of Ulama and many judgees junst in giving legal justice and certainty to the society.   Key Words: Islamic Inheritance Law, Compilation of Islamic Law, Islamic court of  Banten

Five phosphorus rates (0, 5, 10, 20 and 30 kg P/ha) were tested with four rice genotypes in Boro (BRRI dhan36, BRRI dhan45, EH1 and EH2) and T. Aman (BRRI dhan30, BRRI dhan49, EH1 and EH2) season. Phosphorus rates did not influence grain yield irrespective of varieties in T. Aman season while in Boro season P response was observed among the P rates. Application of P @ 10 kg/ha significantly increased the grain yield. But when P was applied @ 20 and 30 kg P/ha, the grain yield difference was not significant. The optimum and economic rate of P for T. Aman was 20 kg P/ha but in Boro rice the optimum and economic doses of P were 22 and 30 kg/ha, respectively. Hybrid entries (EH1 and EH2) used P more efficiently than inbred varieties. A negative P balance was observed up to 10 kg P/ha.

A Value

One indicator of the success ofeducation in the level of classroom learning is when a lecturer is able to build student learning achievement and will be more successful if this achievement can be increased if their attendance is above 80% (minimum 10 times attendance from 12 meetings). If the students can be grown discipline and provided a decent campus facilities, then as difficult as any lecture material or learning process that followed by they undoubtedly will live with feelings of joy, even they will feel sad if that day lecturer could not come because there is a need outside campus.There are four stages of appraisal that apply to each student for each course taken include (1) attendance of 10% (2) Task 20% (3) 30% Semester Exam (UTS) and (4) Final Exam Semester. (UAS) 40%. The writer as a lecturer tries to cultivate motivation to learn from the beginning, in addition to always communicate actively with students who follow the lecture also monitor attendance and assignment, each completed college is always given the practice / tasks are directly given the value, usually given the task quite easily so they can get a value of 100, even if there is a miscalculation, they are still given the opportunity to fix the error so that eventually get a value of 100. With the value of this 100, their motivation to grow and even grow in such a way that spur them to diligent lectures.The difficulty level of the task is balanced with the lecture, the longer it is raised so as to reach the maximum average level of student ability at the end of the lecture meeting...This research reveals that there is no a significant correlation between student achievement to discipline presence of student/mahasiswa with campus facilities. The analyzing was taken from an answer of 55 students who were randomly selected as respondents by filling out the Questionaire that was distributed to them. Key words : achievement, attendance, discipline, campus facility
