The interactions between human serum albumin (HSA) and α- acid glycoprotein (AGP), the main plasma proteins binding drugs/xenobiotics, and some endocrine disrupting chemicals (EDCs), such as bisphenol A (BPA) and some of its structural analogues, bisphenol S (BPS), bisphenol F (BPF), bisphenol E (BPE), bisphenol B (BPB), bisphenol AF (BPAF), bisphenol A diglycidyl ether (BADGE) and bisphenol M (BPM), were characterized by biomimetic liquid chromatography (LC). The interactions between bisphenols (BPs) and either HSA or AGP protein was found to be non-specific and essentially lipophilicity-driven. To get more information on the binding of BPs and plasma proteins, in silico predictions and molecular docking simulations were exploited, and the results achieved in silico were compared to those observed in vitro. BPM was the one exhibiting the highest affinity on both plasma proteins according to these data. Our findings clarified the binding of these EDCs to plasma proteins and offered insights into the biodistribution and bioaccumulation processes underlying their toxicity.

For noninvasive light-based physiological monitoring, optimal wavelengths of individual tissue components can be identified using absorption spectroscopy. However, because of the lack of sensitivity of hardware at longer wavelengths, absorption spectroscopy has typically been applied for wavelengths in the visible (VIS) and near-infrared (NIR) range from 400 to 1,000 nm. Hardware advancements in the short-wave infrared (SWIR) range have enabled investigators to explore wavelengths in the ~1,000 nm to 3,000 nm range in which fall characteristic absorption peaks for lipid, protein, and water.

Background: Acute systemic inflammation affects many organs and it occurs in a wide range of conditions such as acute lung injury (ALI). Inflammation-triggered oxidative pathways together with the caspase activation seen in ALI, result in apoptosis. Dapagliflozin (DPG) is an agent that is known to have oxidative stress-reducing and anti-inflammatory effects in many tissues.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. The roles of the transcription factor special AT-rich binding protein-2 (SATB2) and β-catenin in PDAC have been a subject of controversy. We aimed to assess the diagnostic and prognostic impact of SATB2 and β-catenin in PDAC.

Tumor necrosis factor-α (TNF-α) induces a multitude of actions and consequences in bone and cartilage resorption and immune response augmentation. In this research, we aimed to investigate the effects of TNF-α on osteogenesis parameters in newborn mice. Experimental research was conducted on 42 pregnant mice, dividing into seven groups as follows: control (no injection), vehicle 1 (PBS injection on 7-9th pregnancy days (PD)), vehicle 2 (PBS injection during pregnancy), experimental 1 (injection of 10 ng/kg of TNF-α on 7-9th PD), experimental 2 (injection of 100 ng/kg of TNF-α on 7-9th PD), experimental 3 (injection of 10 ng/kg of TNF-α during pregnancy) and experimental 4 (injection of 100 ng/kg of TNF-α during pregnancy).
