Some adaptive test procedures are developed for the generalized Behrens-Fisher problem. The one having a deterministic approach is based on calculating a measure of symmetry from each sample and using them as a basis for choosing between the modifiedWilcoxon-Mann-Whitney test (Fligner and Policello, 1981) and the modified Mood’s median test (Fligner and Rust, 1982). The other one is a probabilistic approach which also uses a combination of the modified Wilcoxon-Mann-Whitney test and the modified Mood’smedian test according to an evidence of asymmetry provided by the p-value from the triples test for symmetry given in Randles, Fligner, Policello, and Wolfe (1980). This probabilistic approach is further modified by using a suitable function of the p-value from the triples test. A simulation study reveals that the modified procedure performs reasonably well in terms of power and attainment of the nominal size.

Cempedak plants are widely distributed in Indonesia, one of which is Kalimantan. Cempedak is a tropical plant, so its potential can be used as an additive in the manufacture of pharmaceutical preparations. Previous studies used cempedak seed starch as a binding agent in tablet formulations. This study aims to determine the effect of variations in concentration and optimum concentration of Cempedak seed starch (Artocarpus champeden) as a filler for Paracetamol tablets. The study used a True Experimental Design design with a posttest-only control group design. Making tablets using the wet granulation method. Data analysis used the one-way ANOVA test followed by the LSD test and the Kruskal-Wallis H test which continued with the Mann Whitney Test as a derivative test of the one-way ANOVA. Granule evaluation includes organoleptic, flow properties, tapping test, and stationary angle test. The results of the evaluation of the granules produced granules produced from each formulation are in accordance with the requirements. Tablet evaluation included organoleptic, uniformity in weight, the hardness of tablet, friability, and disintegration time. The results of the tablet evaluation showed that the maximum concentration of cempedak seeds was found in F1 because it showed the evaluation results that were in accordance with the requirements. In evaluating the uniformity of weight and hardness of tablets with the Kruskal Wallis H test and the Mann Whitney test, the results show that there are differences in each formula with a P-value <0.05. The results of the evaluation of tablet friability and disintegration time with one-way ANOVA test and LSD test showed differences in each formula with a P-value <0.05. Cempedak seed starch (Artocarpus champeden) can be used as a filler in the loading of Paracetamol tablets by the wet granulation method.

Research on the plantar segment has not been widely carried out in Indonesia’s population, even though the plantar segment data will be essential in further research and therapy of plantar-related problems. Therefore, this research intends to describe the plantar profile: the foot arch and the plantar pressure difference between the right and left foot. This research applied a cross-sectional study. Subjects were recruited from the Faculty of Medicine students, Universitas Indonesia, class 2012, with inclusion criteria aged 17-21 years and normal gait. Meanwhile, the exclusion criteria consisted of having postural abnormalities, a history of neuromusculoskeletal disorders in the lower limbs, a history of fractures in the spine and legs, a history of surgery on the spine and legs, and refusing to participate in the study. Research subjects stood on a plantar scanner, conducted at the Anatomy Laboratory, the Faculty of Medicine, Universitas Indonesia. The Mann-Whitney test was then used to analyze the difference in plantar pressure between the right and left foot. The results revealed that a hundred research subjects had a proportion of a low foot arch of 4%, a normal foot arch of 89%, and a high foot arch of 7%. The median right plantar pressure was 273.5 KPa, while the median left plantar pressure was 253.5 KPa. The Mann-Whitney test showed a p-value of 0.954 for the pressure difference between right and left foot. There was no plantar pressure difference between the right and left foot.

Σκοπός Με βάση περιπτώσεις μοριακού μιμητισμού μεταξύ των γλυκοπρωτεϊνών και των υποδοχέων τους, διατυπώσαμε την υπόθεση ότι αυτοαντισώματα έναντι του υποδοχέα της θυρεοτροπίνης (TSH-Rab) κατασταλτικού τύπου (blocking) πιθανά να έχουν δραστικότητα αποκλειστή επί του υποδοχέα της ανθρώπινης χοριακής γοναδοτροπίνης (LH/hCG-R) στο ωχρό σωμάτιο, το τελικό βιολογικό αποτέλεσμα της οποίας θα ήταν η απώλεια κύησης κατά το πρώτο τρίμηνο. Ο σκοπός της μελέτης ήταν η κλινική διερεύνηση της παραπάνω υπόθεσης και συγκεκριμένα η διερεύνηση της παρουσίας και εκτίμηση των συγκεντρώσεων bTSH-Rab στις γυναίκες με θυρεοειδίτιδα Hashimoto και ιστορικό καθ’ έξιν αποβολών (ασθενείς) και η σύγκριση τους με γυναίκες με θυρεοειδίτιδα Hashimoto και φυσιολογικό αναπαραγωγικό ιστορικό (μάρτυρες). Ασθενείς και Μέθοδοι Συνολικά επιλέχθηκαν 86 γυναίκες (46 ασθενείς και 46 μάρτυρες με ηλικιακή εξομοίωση) από εξωτερικά ιατρεία και κλινικές του Νομού Θεσσαλονίκης στο πλαίσιο αναδρομικής μελέτης τύπου ασθενών-μαρτύρων. Για τη συμπερίληψη στην ομάδα των ασθενών, η γυναίκα έπρεπε να είχε ηλικία μικρότερη των 35 ετών στην τελευταία αποβολή και κάτω των 50 ετών κατά την επιλογή, χωρίς να εντοπίζονταν από το ιστορικό, την κλινική εξέταση και τον κατά περίπτωση παρακλινικό έλεγχο, δευτεροπαθείς αιτίες καθ’ έξιν αποβολών. Σε υπο-ομάδα των ασθενών (n=15) πραγματοποιήθηκε ορμονολογική εκτίμηση υποφυσιακής λειτουργίας, διακολπικό υπερηχογράφημα πυέλου, καρυότυπο, ανίχνευση μεταλλάξεων του παράγοντα V, μέτρηση επιπέδων ομοκυστεΐνης, αυτοαντισωμάτων έναντι της διπλής έλικας του DNA, αντιπηκτικού του λύκου, β2-γλυκοπρωτείνης και αντικαρδιολιπινικών αντισωμάτων. Η στατιστική ανάλυση πραγματοποιήθηκε με το λογισμικό Stata 10.0 Αποτελέσματα Δεν ανιχνεύθηκε σημαντική διαφορά στον επιπολασμό (Fisher’s exact test, p-value = 1.00) ή στους τίτλους TSH-Rab μεταξύ των ασθενών και των μαρτύρων (Mann-Whitney test, p = 0.59). Οι αναλύσεις ευαισθησίας με βάση τους ορισμούς των καθ’ έξιν αποβολών, των αυτόματων αποβολών, της θυρεοειδίτιδας Hashimoto και της θετικότητας των TSH-Rab δεν τροποποίησαν την κατεύθυνση των ευρημάτων. Η απουσία συσχέτισης μεταξύ TSH-Rab και αναπαραγωγικού ιστορικού επιβεβαιώθηκε σε μονομεταβλητό μοντέλο λογαριθμικής παλινδρόμησης [OR = 1.00, 95% CI = 0.19-5.25], είτε όταν χρησιμοποιήθηκε ο τίτλος των TSH-Rab (OR = 0.77, 95% CI = 0.29 - 2.08). Η παρουσία των TSH-Rab δεν προέβλεψε με στατιστικώς σημαντικό τρόπο τον αριθμό των αυτόματων αποβολών στις ασθενείς (Coef = -0.4, 95% CI = -1.15 - 0.34, p = 0.285) και απουσία συσχέτισης επιβεβαιώθηκε όταν χρησιμοποιήθηκε ο τίτλος τους (Coef = -.0.53, 95% CI = -1.08 - 0.10, p = 0.054). Τα παραπάνω ευρήματα παρέμειναν ανθεκτικά στην ιεραρχική στάθμιση με την ηλικία και το ΒΜΙ κατά την τελευταία κύηση ή αποβολή σε πολυμεταβλητά μοντέλα παλινδρόμησης. Συμπεράσματα Στην παρούσα μελέτη, δεν προέκυψαν ενδείξεις ότι τα TSH-Rab έχουν σημαντικό ρόλο στην παθογένεια των αυτόματων αποβολών και δεν μπορεί να υποστηριχθεί η κλινική και ερευνητική χρησιμότητα της ανίχνευσής τους στις γυναίκες με θυρεοειδίτιδα Hashimoto και ιστορικό καθ’ έξιν αποβολών.
