Effect of Young Plasma Therapy on Cognition, Oxidative Stress, miRNA-134, BDNF, CREB, and SIRT-1 Expressions and Neuronal Survey in the Hippocampus of Aged Ovariectomized Rats with Alzheimer's.

Menopause may increase the risk of Alzheimer's disease (AD) dementia. This study aimed to use young plasma therapy (YPT) to improve dementia caused by AD in aged ovariectomized rats. Female Wistar rats were used in the following groups: (a) young (CY) (180-200 g, 2-3 months, n = 10) and (b) old groups (250-350 g, 22-24 months, n = 60).

Angiogenesis concept in odontogenic keratocyst: A comparative study.

Context: Recent reports have indicated that angiogenesis possibly affects the biologic behavior of the lesions.

Aim: Given the different clinical behaviors of odontogenic keratocyst (OKC), the present study was undertaken to evaluate the concept of angiogenesis in pathogenesis and clinical behavior of OKC.

Setting And Design: This experimental study was carried out on 22 and 24 samples of OKCs and dentigerous cysts (DCs), respectively.

Expression of Vascular Endothelial Growth Factor in Odontogenic Cysts: Is There Any Impression on Clinical Outcome?

Background: The recent scientific reports have shown that angiogenesis can affect biological behavior of pathologic lesions.

Objective: Regarding unique clinical outcome of Odontogenic keratocyst (OKC), the present study was aimed to compare angiogenesis in Odontogenic keratocyst and Dentigerous cyst (DC).

Method: In this experimental study, tissue sections of 46 samples of OKC and DC were stained through immunohistochemical method using Vascular Endothelial Growth Factor (VEGF) antibody.
