introduction: skeletal staining is an important part of anatomical studies which can evaluate macroscopic disorders in bones and cartilages development. the aim of the present article is to illustrate two distinct protocols by all details in order to stain skeletal system of the lab animals in all ages of their lives so it becomes easy for future studies in this field. methods: in this paper, s...

introduction: unstained formalin-fixed whole brain specimens and brain slices do not give satisfactory results for teaching neuroanatomy. in addition, difficulties in obtaining human brains for dissection have increased the demand for more durable brain specimens that have been obtained by the plastination technique. in the present study brain specimens were sliced, fixed and stained using the ...

in this paper, we study spacelike dual biharmonic curves. we characterize spacelike dual biharmonic curves in terms of their curvature and torsion in the lorentzian dual heisenberg group . we give necessary and sufficient conditions for spacelike dual biharmonic curves in the lorentzian dual heisenberg group . therefore, we prove that all spacelike dual biharmonic curves are spacelike dual heli...

Preeclampsia (PE) is a severe pregnancy-specific complication responsible for majority of maternal and fetal mortality. The dysfunction trophoblast cells known to be associated with the etiology PE. Moreover, elevated expression hsa_circ_0001326 was found in patients PE without elucidating specific mechanisms. Thus, this study aimed investigate role vitro. Human SWAN71 were used study. Cell pro...

statement of problem: due to the growing popularity of vital bleaching by carbamide peroxide it is imperative to understand the effect of such agents on enamel and dentine. purpose: the purpose of this study was to evaluate the effect of a 16% carbamide peroxide bleaching gel; vivastyle on enamel staining susceptibility. materials and methods: thirty bovine specimens were selected and randomly ...

abstract: introduction & objective: the hippocampal formation is a part of limbic system that plays an important role in memory and learning. the hippocampus is divided into three subfields: ca1, ca2 and ca3. in addition to pyramidal neurons and interneurons, the astrocytes play important roles in hippocampus, probably in memory and learning. in fact, learning needs some instruments for informa...

background: oocyte maturation and subsequent in vitro production (ivp) of embryos are affected by diverse groups of chemicals in maturation medium which are needed for successful mammalian oocyte maturation during which the dramatic cytoplasmic and nuclear reprogramming events take place. this study was designed to evaluate the effects of protein source (fetal bovine serum, fbs, and bovine seru...

background : this study aimed to compare three staining methods including: calcofluor white, chromotrope and quick hot gram chromotrope used in diagnosis of intestinal microsporidial spores . methods : one hundred and seventy five stool specimens were collected from patients referred to laboratory of intestinal protozoology at the school of public health, tehran university of medical sciences d...
