Evaluation of the immunomodulatory effect of Bougainvillea xbuttiana (Var. Orange) on the cytokine production induced by Botrhops jararaca venom in macrophages

To study the effect of 50% ethanol extract of Bougainvillea xbuttiana on the enzymatic activity, cell via bility and cytokine production provoked by the venom of Bothrops jararaca in macro - phages. Three assays were used to study the effects of B. xbuttiana extract on the dama...

Modulación por Passiflora edulis de triglicéridos y colesterol intracelulares en líneas celulares de cáncer colorrectal SW480 y sus derivadas metastásicas (SW620)

Cancer cells modify lipid metabolism to proliferate, Passiflora edulis ( P. edulis ) fruit juice (ZuFru) has antitumor activity, but whether a mechanism is through modulation of cell lipids is unknown. T o establish if ZuFru modifies cholesterol and triglycerides in SW480 and SW620...

Effect of Casearia sylvestris on the obliteration of dentinal tubules and the control of dental sensitivity

The present study evaluated the efficacy of the mineralizing action of Casearia sylvestris ethanolic extract on bovine dentin blocks in its pure form and in dental paste, through scanning electron microscopy. The dentin blocks were immersed in artificial saliva and incubat ed at ...

Differential biological activity of two extracts of ripe fruits of Carica candamarcensis Hook on human neutrophils

We evaluated the effect of the total macerate (TM) and seed oil (SO) of mature Carica candamarcensis fruits, on the release of Matrix metalloproteinase 9 (MMP9) and the phosphorylation of MAPK in neutrophils. The antioxidant capacity of these extracts was evaluated by ABTS a...

Revalidation of nirmatrelvir/ritonavir for the treatment of patients with COVID-19 who are not hospitalized and with a high risk of serious illness

INTRODUÇÃO: Pacientes com fatores de risco como idade avançada, imunodepressão, obesidade e doenças cardiovasculares têm risco aumentado de internação, intubação e morte. De acordo com dados brasileiros, o risco de morte por covid-19 aumenta com o número de fatores de risco que o paciente apre...

Improvement of Na+-K+ ATPase Activity and Gene Expression Associated with Glomerular Ultrastructural Protection in Diabetic Nephropathy by Acacia senegal: Role of Oxidative Stress Disturbances

Int. j. morphol; 42 (1), 2024
SUMMARY: This study assessed the effects of Acacia Senegal (AS) combined with insulin on Na+/K+-ATPase (NKA) activity and mRNA expression, serum glucose, renal function, and oxidative stress in a rat model of diabetic nephropathy (DN). Sixty rats were equally divided into six groups: normal control, norm...

Resveratrol Alleviates Osteoporosis by Promoting Osteogenic Differentiation of Bone Marrow Mesenchymal Stem Cells via SITR1/PI3K/AKT Pathway

Int. j. morphol; 42 (1), 2024
SUMMARY: Senile osteoporosis is mainly caused by reduced osteoblast differentiation and has become the leading cause of fractures in the elderly worldwide. Natural organics are emerging as a potential option for the prevention and treatment of osteoporosis. This study was designed to study the effect of ...

SUMMARY: The objective of this study was to investigate the therapeutic wound healing potential and molecular mechanisms of shikonin as small molecules in vitro. A mouse burn model was used to explore the potential therapeutic effect of shikonin; we traced proliferating cells in vivo to locate the active...

Effect of Brassica rapa var. rapifera on Insulin Resistance and Inflammatory Analysis of Visceral Adipose Tissue of Obese Wistar Rats Under Glucolipotoxicity Condition

Int. j. morphol; 42 (1), 2024
SUMMARY: Obesity-related pathophysiologies such as insulin resistance and the metabolic syndrome show a markedly increased risk for type 2 diabetes and atherosclerotic cardiovascular disease. This risk appears to be linked to alterations in adipose tissue function, leading to chronic inflammation and the...

Fluoruro de estaño en el control de cavidades sin restauración en dientes temporales
Stannous fluoride in nonrestorative cavity control in primary teeth

Rev. ADM; 81 (1), 2024
Introducción: el control de cavidades sin restauración (NRCC, por sus siglas en inglés), es una opción de tratamiento conservador y no invasivo para dentina cariosa, sobre todo en dentición temporal. Una de las estrategias del NRCC es la remineralización. El fluoruro de estaño (FDE) puede consi...
