Connective Tissue Reaction to White and Gray MTA Mixed With Distilled Water or Chlorhexidine in Rats
INTRODUCTION: The purpose of this study was to compare the histocompatibility of white (WMTA) and gray (GMTA) mineral trioxide aggregate mixed with 0.12% chlorhexidine (CHX) and distilled water (DW) in subcutaneous connective tissues of rats. MATERIALS AND METHODS: The freshly mixed WMTA and GMTA with CHX or DW were inserted in polyethylene tubes and implanted into dorsal subcutaneous connective tissue of 50 Wistar Albino rats; tissue biopsies were collected and were then examined histologically 7, 15, 30, 60 and 90 days after the implantation procedure. The histology results were scored from 1-4; score 4 was considered as the worst finding. Data were analyzed using one-way ANOVA tests. RESULTS: All experimented materials were tolerated well by the connective tissues after 90-day evaluation, except for the WMTA/CHX group that had significantly more mean inflammatory scores (P<0.001). There was a statistically significant difference in the mean inflammation grades between experimental groups in each interval (P<0.001). After 90 days, GMTA/CHX group had the lowest inflammatory score. CONCLUSION: Although adding CHX to WMTA produces significantly higher inflammatory response, it seems a suitable substitute for DW in combination with GMTA. Further research is necessary to recommend this mixture for clinical use
Investigating the Influence of Mass Media on Cosmetics Usage among Women in Kashan during 2015
The use of cosmetics is very common among women in Iran. Given the importance of the use of mass media and the impact on the consumption of cosmetics, this study attempted to consider the influence of mass media on the use of cosmetics among women in Kashan. Using a standard designed questionnaire, the data were obtained from 800 women. Multi-stage cluster sampling was randomly carried out. The data were analyzed using SPSS statistical software. The findings showed that 59.9% of the participants believed that satellite programs have the greatest impact on the use of cosmetics. 33% of the participants who believed that mass media had significant influence in this regard; they had a constant tendency to use cosmetics. Mass media advertisements encourage women to consume cosmetics; therefore, introducing the real and appropriate cultural models via advertisements on mass media may have positive impacts on women to consume cosmetics properly
Empagliflozin alleviates renal inflammation and oxidative stress in streptozotocin-induced diabetic rats partly by repressing HMGB1-TLR4 receptor axis
Objective(s): Empagliflozin, a sodium-glucose cotransporter-2 (SGLT-2) inhibitor, possesses verified anti-inflammatory and anti-oxidative stress effects against diabetic nephropathy. The present investigation aims to examine empagliflozin effects on the renal levels of high mobility group box-1 (HMGB1), a potent inflammatory cytokine, and its respective receptor toll-like receptor-4 (TLR-4) in STZ-induced diabetic rats.Materials and Methods: Empagliflozin at 10 mg/kg per os (p.o.) was administered for 4 weeks, starting 8 weeks after the induction of diabetes. Renal function, kidney inflammation, oxidative stress, and apoptosis markers as well as renal HMGB1, receptor for advanced glycation end products (RAGE), and TLR-4 levels were assessed.Results: In addition to down-regulating NF-κB activity in renal cortices, empagliflozin reduced renal levels of HMGB1, RAGE, and TLR-4. It alleviated renal inflammation as indicated by diminished renal expressions of inflammatory cytokines and chemokines like tumor necrosis factor-alpha (TNF-α) and monocyte chemoattractant protein-1 (MCP-1) and also decreased urinary levels of interleukin-6 (IL-6) and alpha-1 acid glycoprotein (AGP). Moreover, empagliflozin ameliorated renal oxidative stress as demonstrated by decreased renal malondialdehyde (MDA) and elevated renal activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX). It also suppressed renal caspase-3, the marker of apoptosis; and furthermore, enhanced renal function noticed by the declined levels of serum urea and creatinine.Conclusion: These findings underline that empagliflozin is able to attenuate diabetes-related elevations in renal HMGB1 levels, an influential inflammatory cytokine released from the necrotic and activated cells, and its correspondent receptors, i.e., RAGE and TLR-4
The Effects of Cetirizine on P-glycoprotein Expression and Function In vitro and In situ
Purpose: P-glycoprotein (P-gp) plays a major role in
oral absorption of drugs. Induction or inhibition of P-gp by drugs contributes
to variability of its transport activity and often results in clinically
relevant drug-drug interactions. The purpose of this study was to investigate
the effect of cetirizine, a second generation H1 antihistamine, on
P-gp function and expression in vitro and in situ.
Methods: The in-vitro rhodamin-123 (Rho123) efflux assay in Caco-2
cells was used to study the effect of cetirizine on P-gp function. Western blot
analysis was used for surveying the effect of cetirizine on expression of P-gp
in Caco-2 cells. Rat in situ single-pass intestinal permeability
technique was used to calculate the intestinal permeability of a known P-gp
substrate (digoxin) in the presence of cetirizine. The amounts of digoxin and
cetirizine in intestinal perfusion samples were analyzed using a HPLC method.
Results: The results showed significant increase in Rho123 uptake (P < 0.05) and also P-gp band intensity decrease in
cetirizine-treated cells in vitro. Furthermore the intestinal
permeability of digoxin was also increased significantly in the presence of
cetirizine (P
< 0.01).
Conclusion: Therefore it is concluded that cetirizine is a P-gp inhibitor and
this should be considered in co administration of cetrizine with other P-gp
substrate drugs. Further investigations are required to confirm our results and to
determine the mechanism underlying P-gp inhibition by cetirizine
Inhibitory effect of clemastine on P-glycoprotein expression and function: an in vitro and in situ study
Objective(s):Transporters have an important role in pharmacokinetics of drugs. Inhibition or induction of drug transporters activity can affect drug absorption, safety, and efficacy. P-glycoprotein (P-gp) is the most important membrane transporter that is responsible for active efflux of drugs. It is important to understand which drugs are substrates, inhibitors, or inducers of P-gp to minimize or avoid unwanted interactions. The aim of this study was to investigate the effects of clemastine on the expression and function of P-gp.
Materials and Methods: The effect of clemastine on P-gp function and expression was evaluated in vitro byrhodamine-123 (Rho123) efflux assay in Caco-2 cells and Western blot analysis. Rat in situ single pass intestinal permeability model was used to investigate the clemastine effect on digoxin Peff, as a known P-gp substrate. Digoxin levels in intestinal perfusates were assayed by high performance liquid chromatography (HPLC) method.
Results:The Caco-2 intracellular accumulation of Rho123 in clemastine and verapamil treated cells was 90.8 ± 9.8 and 420.6±25.4 pg/mg protein, respectively which was significantly higher than that in control cells (50.2±6.0;
Probiotic assisted weight management as a main factor for glycemic control in patients with type 2 diabetes: a randomized controlled trial
Abstract Objectives To evaluate the effect of Lactobacillus casei 01 on dietary intake, body weight, and glycemic control in patients with T2DM. Method Forty patients with T2DM (n = 20 for each group) were assigned into two groups in present trial. The patients in the probiotic group received a daily capsule containing a minimum of 108 CFU of L. casei 01 for 8 week. The placebo group took capsules filled with maltodextrin for the same time period. Dietary intake questionnaires and anthropometric measurements were collected, and the participants were assessed by an endocrinologist at baseline and at the end of the trial. Results Lactobacillus casei 01 supplementation significantly decreased total energy, carbohydrate, fat, and protein intake compared with placebo (p = 0.001, p = 0.002, p = 0.009, p = 0.001; respectively). Moreover weight, BMI, and waist circumference were significantly decreased in intervention group compared with placebo group (p < 0.001; p < 0.001; p = 0.029; respectively). In comparison with placebo group serum fetuin-A level, fasting blood sugar, insulin concentration, and insulin resistance were significantly decreased (p = 0.023, p =0.013, p = 0.028; p = 0.007; respectively), and serum SIRT1 level was significantly increased (p = 0.040) in intervention group. Conclusions Lactobacillus casei 01 supplementation affected dietary intake and body weight in a way that improved fetuin-A and SIRT1 levels and glycemic response in subjects with T2DM. Affecting the fetuin-A and SIRT1 levels introduces a new known mechanism of probiotic action in diabetes management
Unveiling the potential effects of resveratrol in lung cancer treatment: Mechanisms and nanoparticle-based drug delivery strategies
Lung cancer ranks among the most prevalent forms of cancer and remains a significant factor in cancer-related mortality across the world. It poses significant challenges to healthcare systems and society as a whole due to its high incidence, mortality rates, and late-stage diagnosis. Resveratrol (RV), a natural compound found in various plants, has shown potential as a nanomedicine for lung cancer treatment. RV has varied effects on cancer cells, including promoting apoptosis by increasing pro-apoptotic proteins (Bax and Bak) and decreasing anti-apoptotic proteins (Bcl-2). It also hinders cell proliferation by influencing important signaling pathways (MAPK, mTOR, PI3K/Akt, and Wnt/β-catenin) that govern cancer progression. In addition, RV acts as a potent antioxidant, diminishing oxidative stress and safeguarding cells against DNA damage. However, using RV alone in cancer treatment has drawbacks, such as low bioavailability, lack of targeting ability, and susceptibility to degradation. In contrast, nanoparticle-based delivery systems address these limitations and hold promise for improving treatment outcomes in lung cancer; nanoparticle formulations of RV offer advantages such as improved drug delivery, increased stability, controlled release, and targeted delivery to lung cancer cells. This article will provide an overview of lung cancer, explore the potential of RV as a therapeutic agent, discuss the benefits and challenges of nanoparticle-based drug delivery, and highlight the promise of RV nanoparticles for cancer treatment, including lung cancer. By optimizing these systems for clinical application, future studies aim to enhance overall treatment outcomes and improve the prognosis for lung cancer patients
