This review aimed to highlight the historical perspectives focused on histological stains and their application in teaching research. While early histologists used indigenous substances like alizarin, carmine, saffron stain tissues, modern utilize techniques that study cellular organelles within tissues. Despite advent of new staining techniques, modification old ones, decrease use natural dyes...

A punch biopsy of the axillary region was performed for histopathological study, staining with hematoxylin-eosin (Figure 2), periodic acid-Schiff (PAS), and Congo red. The histological findings included papillomatosis, orthokeratotic hyperkeratosis and epidermal acanthosis, focal atrophy of the granular layer, and mild hyperpigmentation of the basal layer of the epidermis. There was a moderate ...

BACKGROUND There are no published studies on stem cells from equine cord blood although commercial storage of equine cord blood for future autologous stem cell transplantations is available. Mesenchymal stem cells (MSC) have been isolated from fresh umbilical cord blood of humans collected non-invasively at the time of birth and from sheep cord blood collected invasively by a surgical intrauter...

BACKGROUND Mesenchymal stromal cells (MSCs) are multipotent progenitor cells that originally derived from bone marrow. Clinical use of bone marrow-derived MSC is difficult due to morbidity and low MSC abundance and isolation efficiency. Recently, MSCs have been isolated from various adult tissues. Here we report the isolation of adenoid tissue-derived MSCs (A-MSCs) and their characteristics. ...

BACKGROUND Adiantum philippense (AP) is a pteridophyte that shows antihyperglycemic activity in vivo diabetic model, but the mechanism of action is unknown. OBJECTIVE AP was found to play a pivotal role in minimizing the high blood glucose in alloxan-induced diabetic rats. Simultaneously, it was observed that it could maintain the normal lipid profile even in diabetic condition. To investigat...

RATIONALE Arterial calcification and osteoporosis are associated in postmenopausal women. RANK (the receptor activator of nuclear factor kappaB), RANKL (RANK ligand), and osteoprotegerin are key proteins in bone metabolism and have been found at the site of aortic calcification. The role of these proteins in vasculature, as well as the contribution of estrogen to vascular calcification, is poor...

BACKGROUND rotator cuff muscle atrophy, fibrosis and fatty infiltration are common complications after large and massive rotator cuff tears. Currently, there are no effective treatments for these muscle pathologies after injury. Furthermore, the cellular source for fibrotic and adipose tissues in rotator cuff muscle after injury remains unknown. In this study, we proposed that two groups of mus...

background autologous platelet concentrate has been used to improve the function and regeneration of injured tissues. tendinopathies are common in clinical practice, although long-term treatment is required. on the basis of lead time, we compared the effect of using platelet-rich plasma (prp) and platelet-rich fibrin (prf) in repairing rat achilles tendon. methods the effectiveness of using prp...
