A new oxaliplatin analog [Pt(dach)(L5)] (1) was synthesized and characterized as a continuation of a study of the previously reported [Pt(dach)(L6)] (2), where dach = (1R,2R)-diaminocyclohexane, L5 = 3-carboxyboldine, and L6 = 3-carboxypredicentrine. Compounds 1 and 2 exhibited a substantially enhanced antioxidant activity compared to oxaliplatin (130 and 30 times for 1 and 13 and 4 times for 2 using the DPPH and FRAP assays, resp.). In addition, 1 and 2 exhibited cytotoxic activity in the same range as oxaliplatin toward the two human tumor cell lines (MCF-7 and HT-29) studied and two to four times lower activity in the human colon nontumor cell line (CCD-841). Preadministration of L5 or L6 to the colon tumor (HT-29) and the colon nontumor (CCD-841) cell lines prior to oxaliplatin addition increased the viability of the nontumor cell line to a greater extent than that of the tumor cell line.

Background: Piperine, a secondary metabolite, affects the antihyperlipidemic effect of Ezetimibe (EZ). Hyperlipidemia is one of the independent risk factors for cardiovascular disorders such as atherosclerosis. Antihyperlipidemic drugs are essential for reducing cardiovascular events and patient mortality.

Background: The Microtubules-associated protein tau (MAPT), alpha-synuclein (SNCA), and leucine zipper tumor suppressor 3 (LZTS3) genes are implicated in neurodegeneration and tumor suppression, respectively. This study investigated the regulatory roles of eugenol on paraquat-altered genes.
Results: Forty male Wistar rats divided into five groups of eight rats were used.

Background: This study aimed to assess the influence of different pretreatment protocols and antioxidants application on the shear bond strength (SBS) of universal adhesive to sound (SoD) and caries-induced dentin (CID).
Methods: One hundred and twenty posterior teeth had their occlusal enamel removed, then the specimens were divided into two main groups according to dentin substrates; SoD and CID, three subgroups according to pretreatments protocols control (no pretreatment), NaOCl-treated, and Er, Cr:YSGG-treated and two divisions according to antioxidant application (with and without sodium ascorbate (SA) application). All-Bond Universal (ABU) universal adhesives was applied in self-etch (SE) mode then resin composite discs were built.

Background: Preserving plant genetic resources is essential for tackling global food security challenges. Effectively meeting future agricultural demands requires comprehensive and efficient assessments of genetic diversity in breeding programs and germplasm from gene banks. This research investigated the diversity of pheno-morphological traits, along with the fatty acid and tocopherol content and composition, in 135 double haploid lines of camelina.

Rationale: One of the most debilitating drawbacks of cisplatin chemotherapy is neurotoxicity which elicits memory impairment and cognitive dysfunction (chemobrain). This is primarily triggered by oxidative stress and inflammation. Captopril, an angiotensin-converting enzyme inhibitor, has been reported as a neuroprotective agent owing to its antioxidant and anti-inflammatory effects.
