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 ...

background: multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. a rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles.objectives: herein, we report on a simple approach for the synthesis of ma...

Dysregulation of hedonic processing, in which seeking of drug reward becomes more desirable than seeking natural rewards, like food, sex, and novelty, is a consequence of chronic drug exposure and potentially leads to escalating drug usage and addiction. Here, we investigated the effects of chronic cocaine treatment (10 days of escalating doses of cocaine, 10-30 mg/kg) and multiple forced absti...

Schistosoma mansoni eggs are classified, according to morphological characteristics, as follows: viable mature and immature eggs; dead mature and immature eggs, shells and granulomas. The scope of this study was to compare the staining characteristics of different morphological types of eggs in the presence of fluorescent labels and vital dyes, aiming at differentiating live and dead eggs. The ...

The overall goal of this study was to fabricate multifunctional core-shell microcapsules with biological cells encapsulated within the polymer shell. Biocompatible temperature responsive microcapsules comprised of silicone oil droplets (multicores) and yeast cells embedded in a polymer matrix (shell) were prepared using a novel microarray approach. The cross-linked polymer shell and silicone mu...

The distribution of m4 muscarinic acetylcholine receptors, and their relation to a number other markers, was examined using immunocytochemical techniques. Staining in the dorsal striatum tended to be more pronounced in the striosomal than the matrix compartment of both rats and cynomolgus monkeys. Within the ventral striatum, immunoreactivity was more pronounced within the olfactory tubercle an...

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 ...
