Use of microemulsion in enhanced oil recovery has become more attractive in recent years because of its high level of extraction efficiency. Experimental investigations have been made on characterization of microemulsions of oil-brinesurfactant/cosurfactant system for its use in enhanced oil recovery (EOR). Sodium dodecyl sulfate, propan-1-ol and heptane were selected as surfactant, cosurfactan...

BACKGROUND We evaluated the effect of vitamin E and metformin on fatty liver disease in obese children. METHODS This interventional study has been done on 119 children with Non-alcoholic fatty liver disease (based on sonography results). Patients were divided into four treatment groups; they received metformin 1gr daily (age< 12 years), metformin 1.5 gr daily (age> 12 years), vitamin E 800 U ...

Each Gr-functor of the type (φ, f) of a Gr-category of the type (Π, C) has the obstruction be an element k ∈ H(Π, C). When this obstruction vanishes, there exists a bijection between congruence classes of Gr-functors of the type (φ, f) and the cohomology group H(Π,C). Then the relation of Gr-category theory and the group extension problem can be established and used to prove that each Gr-catego...

Ein Leitartikel im 4. Heft des Jahres 2005 der GMS ZMed Ausbild [1] stellte mit Genugtuung fest, dass die Gesellschaft für Medizinische Ausbildung (GMA) sich in einer überaus dynamischen Entwicklung befand, sich die Mitgliederzahl in den zwei Jahren zuvor auf 400 verdoppelt hatte und insbesondere jüngereMitglieder die Aktivitäten der GMA belebten, darunter auchmehr als 70 Studierende. Die Wahrn...

Transporters are major determinants of the disposition of xenobiotics and endogenous chemicals in the body. Organic anion transporter 3 (Oat3) functions in the kidney and brain to remove metabolic waste, toxins, and drugs, and thus transports diverse chemicals. Some b-lactam antibiotics interact with Oat3, and penicillin G exhibits a strong dependence on Oat3 for renal elimination. However, ove...

BACKGROUND The relationship between male infertility and gr/gr deletions that remove multiple genes of the Y chromosome varies among countries and populations. The aim of this study was to investigate the association between gr/gr deletions and spermatogenic phenotype in fertile and infertile Japanese men. METHODS The subjects were screened by sequence-tagged site (STS) analysis to detect gr/...

Let n,k,r and t be positive integers, and let [n] = {1,2, . . . ,n}. A family G ⊂ 2[n] is called r-wise t-intersecting if |G1∩·· ·∩Gr| ≥ t holds for all G1, . . . ,Gr ∈ G . Let us define a typical r-wise t-intersecting family Gi(n,r, t) and its k-uniform subfamily Fi(n,k,r, t), where 0 ≤ i ≤ ⌊n−t r ⌋, as follows: Gi(n,r, t) = {G ⊂ [n] : |G∩ [t + ri]| ≥ t +(r−1)i}, Fi(n,k,r, t) = Gi(n,r, t)∩ ([n...
