Film dosage forms containing metronidazole (MZ) were prepared from natural polysaccharides, such as pullulan (PUL) or sodium alginate (ALG), without heating or controlling the pH. The release profiles of MZ from the films were investigated. In the absence of a drug, the casting method resulted in the polysaccharide forming a circular film, and the presence of MZ affected film formation. The thi...
سابقه و هدف: علیرغم تحقیقات بیشماری که در زمینه پوسیدگی دندان به عمل آمده، هنوز بسیاری از جنبه های اتیولوژیک بیماری از جمله ارث، مبهم است. هدف از این مطالعه، بررسی مقایسه ای میانگین شاخص DMFT در دوقلوهای تک تخمکی (Monozygotic) و دو تخمکی (Dizygotic) می باشد.مواد و روشها: تحقیق به صورت توصیفی – تحلیلی و مقطعی انجام شد. با توجه به این اصل که دوقلوهای(Monozygotic) MZ ، ژنتیک یکسان دارند و تفاوت آن...
The origin of monozygotic (MZ) twins is attributed to two or more daughter cells of a single zygote undergoing independent mitotic divisions, leading to independent development and births. It provides the foundation for the assumption that the resulting twins will be genetically identical. This assumption has been used to evaluate the relative role of genes and environment for a variety of mult...
T1 and T2 relaxation times were examined in four pairs of monozygotic (MZ) twins discordant and concordant for schizophrenia with low and high genetic loading for the illness and five healthy control MZ twin pairs. Patients with schizophrenia (n = 11) showed significant prolongation in T1 relaxation times in the globus pallidus (GP) bilaterally (P < 0.005, Bonferroni corrected) when compared to...
Both the B cell antigen receptor (BCR) signaling and Notch signaling pathway play important roles in marginal zone (MZ) B cell development; however, if and how these two signaling pathways engage in crosstalk with each other remain unclear. In the present study, IgH transgenic mice (TgV(H)3B4) were crossed with mice with Notch downstream transcription factor RBP-J floxed alleles (RBP-J(f/f)) an...
In the developing cerebral cortex, the marginal zone (MZ), consisting of early-generated neurons such as Cajal-Retzius cells, plays an important role in cell migration and lamination. There is accumulating evidence of widespread excitatory neurotransmission mediated by γ-aminobutyric acid (GABA) in the MZ. Cajal-Retzius cells express not only GABAA receptors but also α2/β subunits of glycine re...
Splenic marginal zone (MZ) B cells are a lineage distinct from follicular and peritoneal B1 B cells. They are located next to the marginal sinus where blood is released. Here they pick up antigens and shuttle the load onto follicular dendritic cells inside the follicle. On activation, MZ B cells rapidly differentiate into plasmablasts secreting antibodies, thereby mediating humoral immune respo...
The early responses of follicular (Fo) and marginal zone (MZ) B cells to T cell-dependent Ag were compared using anti-hen egg lysozyme (HEL+) B cells capable of class switch recombination and somatic hypermutation (SHM). Purified CD21/(35int)CD23high Fo and CD21/35(high)CD23low MZ splenic B cells from SW(HEL) Ig-transgenic mice were transferred into wild-type recipients and challenged with HEL-...
