Bone samples from a Middle Bronze Age (ca., 1600-1300 BC) site were prepared for histological analysis. Preliminary results suggested that components of bone marrow remained preserved. To verify these findings and optimize the sample preparation procedure, we conducted experiments varying the type of acid used to decalcify the bones for histology preparation, as well as the exposure time to the...

The present study puts forth the morphometric analysis of modifications that occur in the ovarian structures (stroma, parenchyma, blood vessels) before and after menopause onset. Our study was performed on 30 human ovary specimens from patients with no history of genital pathology that were split in two groups (15 ovaries harvested from fertile women and 15 ovaries harvested from women at menop...

A histological technique is described which results in the differential staining of neural crest cells. This is used to describe the formation and early migration of crest cells in the head of the mouse embryo. The first indications of crest formation are seen in the midbrain/anterior hindbrain at 3--4 somites where crest cells accumulate in the basal surface of the ectodermal epithelium near t...

The distribution of plasminogen activator in fresh human prostatic tissue has been studied, using a histological technique. The vascular endothelium consistently showed fibrinolytic activity while inconstant and lesser activity arose from the epithelial cells of glands and ducts. Increased epithelial activity was often accompanied by evidence of trauma. Activity of the secretions was insignific...

The freeze substitution histological technique allows the indirect light microscopicobservation and the quantitative evaluation of ice crystal size in frozen tissues. Theuseofchemical fixatives in substitu ting fluids improves morphological and histochemical preservation of the tissue. Fixation conditions become important since this step can introduce modifications in crystal sizes . Effects of...

BACKGROUND A common approach in exploring register data is to find relationships between outcomes and predictors by using multiple regression analysis (MRA). If there is more than one outcome variable, the analysis must then be repeated, and the results combined in some arbitrary fashion. In contrast, Canonical Correlation Analysis (CCA) has the ability to analyze multiple outcomes at the same ...

Effects of the neutralization of endogenous progesterone with rabbit antiserum to progesterone (anti-progesterone) on germinal vesicle breakdown of ova in follicles of small (less than 125 micrometers), intermediate (125-250 micrometers) and large (greater than 250 micrometers) diameter were examined by a quantitative histological technique. Immature rats were treated with 5 IU pregnant mare's ...

Three techniques for staining the secretory neurones in sections were applied directly to the whole brain and/or intact organs of the neuro-endocrine system of certain insects, and the whole brain of various invertebrates and vertebrates. After minor changes in the original procedures, in situ staining was achieved in those components of the neuro-endocrine system that are known to contain the ...

background in recent years, there is an increasing tendency to use diced cartilage grafts in rhinoplasty surgery for improving dorsum contour irregularities. this study was designed to compare graft resorption between three techniques of diced cartilage using surgical blade, electrical grinder and grater in rabbit model. methods thirteen new zealand rabbits were divided into three groups. three...

background: esophageal cancer is the sixth cause of death in the world, there was a lack of population‑based information on the trend and incidence rate of esophagus cancer, so this study aimed to determine the incidence and pathological changes of esophagus cancer in iran. methods: in this study, data were extracted from annual cancer registry reports of iranian ministry of health between 2003...
