The present study with aim at enhancing the therapeutic and anti-cancer properties of cisplatin (CPT)-loaded bovine serum albumin (BSA) nanoparticles. Selleck PGE2 The BSA nanoparticles containing CPT (CPT-BSANPs) were successfully prepared by the desolvation technique. The physicochemical characterization of the CPT-BSANPs were used by Fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The particle size of CPT-BSANPs was found less than 200 nm with 75.02 ± 0.15% entrapment efficiency (EE), while zeta potential and PDI were -17.6 mV and 0.2, respectively. In vitro release behavior of the CPT from the carrier suggests that about 64% of the drug gets released after 48 hrs. The anti-cancer activities of the CPT-BSANPs were tested on MCF-7 cell lines. Our studies show that CPT-BSANPs nanoparticles showed specific targeting and enhanced cytotoxicity to MCF-7 cells when compared to the bare CPT. Thus results suggest that CPT-BSANPs fallowed caveolae-mediated endocytosis, it may become better option for intracellular delivery of anticancer drug.Over the past decade, despite the controversies surrounding prostate cancer screening, significant refinements have improved its application. PSA screening, although it has been questioned, appears to confer a mortality benefit and remains the most effective way to identify the possible presence of prostate cancer. Methods to improve the specificity of PSA screening and limit overdiagnosis of indolent cancers, including risk-stratified screening regimens, are currently being utilized. Certain imaging modalities, such as multiparametric MRI, have proven to be excellent adjuncts providing improved risk stratification and the ability for targeted biopsies; however, concerns over variability in interpretation and generalizability persist. A number of novel biomarkers have become available with nearly all demonstrating the ability to improve upon the specificity of PSA screening; however, optimal timing, direct comparisons, and usefulness in conjunction with imaging modalities remain to be elucidated. With the improvement in testing options and recognition of the risk/benefit ratio for men undergoing screening for prostate cancer, the increasing role of shared decision making in the process is emphasized.

Endothelial dysfunction is a driving force during the development and progression of cardiovascular complications in diabetes. Targeting endothelial injury may be an attractive avenue for the management of diabetic vascular disorders. Chicoric acid is reported to confer antioxidant and anti-inflammatory properties in various diseases including diabetes. However, the role and mechanism of chicoric acid in hyperglycemia-induced endothelial damage are not well understood.

In the present study, human umbilical vein endothelial cells (HUVECs) were incubated with high glucose/high fat (HG + HF) to induce endothelial cell injury.

We found that exposure of HUVECs to HG + HF medium promoted the release of cytochrome c (cytc) from mitochondrion into the cytoplasm, stimulated the cleavage of caspase-3 and poly ADP-ribose-polymerase (PARP), then inducing cell apoptosis, the effects that were prevented by administration of chicoric acid. Besides, we found that chicoric acid diminished HG + HF-induced phosphorylationssociated vascular endothelial injury.

Sevoflurane is a widely used anesthetics, however, it has been reported that sevoflurane has neurotoxic effects. Studies have shown that miR-221-3p can ameliorate neuron damage. This study was to investigate whether miR-221-3p could reduce the neurotoxic effect of sevoflurane on nerve cells.

The rat hippocampal neuron cells were treated with sevoflurane or cultured normally. And we constructed neuron cells that overexpressed or low expression of miR-221-3p in the presence or absence of sevoflurane. The cells were transfected with CDKN1B or siCDKN1B, and co-transfected with miR-221-3p mimic and CDKN1B or miR-221-3p inhibitor and siCDKN1B. Cell viability and apoptosis were detected by CCK-8 and flow cytometer. Target gene of miR-221-3p were predicted by TargetScan and luciferase reporter assay. The expressions of related genes were detected by western blotting and quantitative real-time polymerase chain reaction.

Sevoflurane decreased miR-221-3p level and increased CDKN1B level, inhibited cell viability and promoted apoptosis. Overexpress of miR-221-3p decreased CDKN1B level, up-regulated cell viability and inhibited apoptosis, and reversed the effects of sevoflurane on cell viability and apoptosis, while the effects low expression of miR-221-3p was contrary. CDKN1B was the target gene of miR-221-3p, which inhibited cell viability and promoted apoptosis, and reversed the effects of miR-221-3p mimic, whereas siCDKN1B did the opposite effects.

Sevoflurane can cause nerve cell injury, and miR-221-3p may promote cell activity and inhibit apoptosis by inhibiting CDKN1B expression, thereby ameliorating cell injury induced by sevoflurane.

Sevoflurane can cause nerve cell injury, and miR-221-3p may promote cell activity and inhibit apoptosis by inhibiting CDKN1B expression, thereby ameliorating cell injury induced by sevoflurane.Aluminum (Al), a neurotoxic element, can induce Alzheimer's disease (AD) via triggering neuronal death. Ferroptosis is a new type of programmed cell death related to neurological diseases. Unfortunately, its role in aluminum-induced neuronal death remains completely unclear. This study aimed to investigate whether ferroptosis is involved in neuronal death in response to aluminum exposure as well as its underlying mechanism. In this study, rat adrenal pheochromocytoma (PC12) cells were treated with 200 μM aluminum maltolate (Al(mal)3) for 24 h, and related biochemical indicators were assessed to determine whether ferroptosis was induced by aluminum in neurons. Then, the potential mechanism was explored by detecting of these genes and proteins associated with ferroptosis after adding ferroptosis-specific agonist Erastin (5 μM) and antagonist Ferrostatin-1 (Fer-1) (5 μM). The experimental results demonstrated that aluminum exposure significantly increased the death of PC12 cells and caused specific mitochondrial pathological changes of ferroptosis in PC12 cells.
