2. Physiological potential of soybean seeds and its relationshipto electrical conductivity
Resumo: O teste de condutividade elétrica (CE) é capaz de detectar a deterioração de sementes ainda em sua fase inicial, tendo em vista que está relacionado com a desorganização das membranas celulares. Deste modo, o presente trabalho teve por objetivo o estudo da utilização do teste de CE como alternativa para avaliação de vigor de sementes de so

3. Schizandrin A exerts anti-tumor effects on A375 cells by down-regulating H19
Malignant melanoma (MM) is one of the malignant tumors with highly metastatic and aggressive biological actions. Schizandrin A (SchA) is a bioactive lignin compound with strong anti-oxidant and anti-aging properties, which is stable at room temperature and is often stored in a cool dry place. Hence, we investigated the effects of SchA on MM cell line A375 an

4. Bullous pemphigoid
Abstract: Bullous pemphigoid is the most frequent autoimmune bullous disease and mainly affects elderly individuals. Increase in incidence rates in the past decades has been attributed to population aging, drug-induced cases and improvement in the diagnosis of the nonbullous presentations of the disease. A dysregulated T cell immune response and synthesis of

5. The in vivo effect of L-arginine on skin elasticity in mice
ABSTRACT The human skin aging process is a complex mechanism that can be induced both by intrinsic and extrinsic factors. Observations include a decrease in the biosynthetic and proliferative capacity of cells, increased expression of matrix metalloproteinases, reduction in collagen type I expression, and the progressive disappearance of elastic tissue in th

6. Numeric and volumetric changes in Leydig cells during aging of rats
Abstract Purpose: To analyze the effects of aging in rats on the nuclear volume, cytoplasmic volume, and total volume of Leydig cells, as well as their number. Methods: Seventy-two Wistar rats were divided into six subgroups of 12 rats, which underwent right orchiectomy at 3, 6, 9, 12, 18, and 24 months of age. The weight and volume of the resected testic

7. A scientific survey on 1550 cases of oral lesions diagnosed in a Brazilian referral center
ABSTRACT The present study aimed to perform an epidemiological survey on the prevalence rate of oral lesions diagnosed in a referral center in Brazil and to establish association between the lesions and the age and gender of the affected patients. This analytical observational study analyzed 3521 medical records of anatomopathological exams of the Pathologic

8. Evaluation of basil extract ( Ocimum basilicum L.) on oxidative, anti-genotoxic and anti-inflammatory effects in human leukocytes cell cultures exposed to challenging agents
ABSTRACT Ocimum is one of the most important genera of the Lamiaceae family. Several studies about basil and its popular use reveal many characteristics of the herb, including its use as antioxidant, anti-aging, anti-inflammatory, anti-carcinogenic, anti-microbial, and cardiovascular agents, among others. In this paper, we evaluated genotoxic, oxidative, and

9. Aging impairs osteoblast differentiation of mesenchymal stem cells grown on titanium by favoring adipogenesis
ABSTRACT Aging negatively affects bone/titanium implant interactions. Our hypothesis is that the unbalance between osteogenesis and adipogenesis induced by aging may be involved in this phenomenon. Objective We investigated the osteoblast and adipocyte differentiation of mesenchymal stem cells (MSCs) from young and aged rats cultured on Ti. Material and M

10. In vitro and in vivo evaluation of efficacy and safety of photoprotective formulations containing antioxidant extracts
ABSTRACT Chronic exposure to solar radiation could contribute to premature skin aging and skin cancer. Skin presents its own antioxidant defense, however when defenses are out of balance, reactive oxygen species could damage biological structures. In the present work, an oil-in-water photoprotective emulsion was developed and Bauhinia microstachya var. massa

11. Oral Lesions in Elderly Patients in Referral Centers for Oral Lesions of Bahia
Introduction The aging population phenomenon is occurring on a global scale; aging affects all of the structures of organisms, including the oral cavity. Objective To estimate the frequency of oral lesions, according to the clinical and histopathologic diagnoses, and to describe the sociodemographic profile of the elderly treated at the referral centers

12. Confocal Raman spectroscopy: determination of natural moisturizing factor profile related to skin hydration
INTRODUCTION: Skin health and skin care to reduce the effects of aging are the main interests of many researchers. The skin is very important because it protects the body from various effects of the external environment, and studies of the largest organ of the human body have been conducted since antiquity. In skin, aging effects are severe enough to promote
