Assessing the effect of sunlight exposure and reuse of polyethylene terephthalate bottles on phthalate migration.

Nowadays, polyethylene terephthalate (PET) bottles are widely used for packaging drinks and food. However, concerns have been raised about the possible migration of harmful chemicals, particularly phthalates, from these containers into their contents. Therefore, this study investigates the effects of sunlight exposure and PET bottle reuse on phthalate migration, focusing on three common phthalates: bis(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), and benzyl butyl phthalate (BBP).

Mechanochemical Functionalization of Oxidized Carbon Black with PLA.

The functionalization of carbon black (CB) represents a promising strategy to enhance its compatibility with polymers while addressing sustainability concerns. In this study, a solvent-free mechanochemical approach (ball milling) is proposed for the functionalization of oxidized carbon black (oCB) with post-consumed polylactic acid (PLA), overcoming the environmental drawbacks of conventional methods that mostly rely on toxic solvents and catalysts. The functionalized carbon black (f-CB) was characterized by Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA), and thermogravimetric analysis (TGA) to confirm the successful modification.

Protective effects of polydatin amphiphilic chitosan nanocarriers against an aluminum chloride-induced model of Alzheimer's disease in rats: relevance to its anti-inflammatory and antioxidant effects.

Alzheimer's disease (AD) is the most frequent cause of dementia. Since there are complex pathophysiological mechanisms behind AD, and there is no effective treatment strategy, it is necessary to introduce novel multi-targeting agents with fewer side effects and higher efficacy. Polydatin (PD) is a naturally occurring resveratrol glucoside employing multiple mechanisms toward neuroprotection.

Investigating the Risk Factors Associated with Type 1 Diabetes (T1D) in the South of Iran: A Casecontrol Study.

Background: Type 1 diabetes (T1D) is an autoimmune disorder characterized by a complex interplay of genetic and environmental factors.

Aim: The objective of this study was to identify the risk factors associated with T1D in the southern region of Iran during the year 2022.

Methods: This research employed a case-control design involving two groups (79 individuals in each group) of healthy children and adolescents diagnosed with T1D.

Novel Insights on the Biology and Immunological Effects of Histamine: A Road Map for Allergists and Mast Cell Biologists.

Histamine (CHN, molecular weight 111.15 g/mol) is a well-studied endogenous biogenic amine composed of an imidazole ring attached to an ethylamine side chain. It has a limited half-life of a few minutes within tissues and in circulation.
