Enhancing renal protection against cadmium toxicity: the role of herbal active ingredients.

Toxicol Res (Camb)

December 2024

Department of Pharmacodynamics and Toxicology, School of Pharmacy, Mashhad University of Medical Sciences, P. O. Box 91779-48954, Mashhad, Iran.

Background: Rapid industrialization globally has led to a notable increase in the production and utilization of metals, including cadmium (Cd), consequently escalating global metal pollution worldwide. Cd, characterized as a persistent environmental contaminant, poses significant health risks, particularly impacting human health, notably the functionality of the kidneys. The profound effects of Cd stem primarily from its limited excretion capabilities and extended half-life within the human body.

Purpose: The management of rectal adenocarcinoma has evolved during the last decade, shifting from a conventional neoadjuvant chemoradiotherapy, surgery, and adjuvant chemotherapy in all cases to a total neoadjuvant approach, especially in locally advanced tumors when a sphincter-sparing surgery has been planned. However, the exact indications and the neoadjuvant regimen with the highest response remain unresolved. We aimed to assess whether administering neoadjuvant chemotherapy before and after preoperative chemoradiotherapy could increase the pathological complete response (pCR) rates.

Ursolic acid, a natural pentacyclic triterpenoid compound, has been shown to have significant cardioprotective effects in various preclinical studies. This article reviews the various mechanisms by which ursolic acid achieves its cardioprotective effects, highlighting its potent anti-oxidant, anti-inflammatory, and anti- apoptotic properties. Ursolic acid upregulates anti-oxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPx), effectively reducing oxidative stress, thereby decreasing reactive oxygen species (ROS) and improving lipid peroxidation levels.

Obesity is a multifactorial condition influenced by genetic, environmental, and microbiome-related factors. The gut microbiome plays a vital role in maintaining intestinal health, increasing mucus creation, helping the intestinal epithelium mend, and regulating short-chain fatty acid (SCFA) production. These tasks are vital for managing metabolism and maintaining energy balance.

Article Synopsis
  • * Researchers conducted a cross-sectional study with 664 women in Mashhad, using the Menopause Severity Symptoms Inventory (MSSI-38) to group women into three clusters based on their symptom severity: mild, moderate, and severe.
  • * Results indicated that women in moderate and severe symptom clusters had significant associations with higher rates of underlying diseases, lack of physical activity, and more pregnancies, with the severe cluster being most affected by factors such as insufficient income and menopause stage.

Article Synopsis
  • - The study explored how different surface treatments affect the bond strength of zirconia with varying yttria contents, using methods like airborne-particle abrasion (APA) and selective infiltration etching (SIE) among others.
  • - Results showed that all treated zirconia specimens had higher bond strength compared to untreated ones, with APA being the most effective across all types of zirconia tested.
  • - While Zolid Zi (4.5-5.6 wt% yttrium) exhibited the highest bond strength, Zolid FX (9.15-9.55 wt% yttrium) had the lowest, indicating that both treatment method and material type significantly influence bond strength and surface roughness.
