Chemotherapy is a key treatment option for gastric cancer, but over 50% of patients develop either inherent or acquired resistance to these drugs, resulting in a 5-year survival rate of only about 20%. The primary treatment for advanced gastric cancer typically involves chemotherapy based on platinum or fluorouracil. Several factors can contribute to platinum resistance, including decreased drug uptake, increased drug efflux or metabolism, enhanced DNA repair, activation of pro-survival pathways, and inhibition of pro-apoptotic pathways.

Serotonin-2B receptor (5-HTR) expression and binding in the brain of APP/PS1 transgenic mice and in Alzheimer's disease brain tissue.

Neurosci Lett

January 2025

Department of Neurobiology, Institute of Molecular Medicine, University of Southern Denmark, Odense, Denmark; Department of Life Sciences, School of Sciences, European University Cyprus, Nicosia, Cyprus. Electronic address:

Despite well-documented dysregulation in central serotonergic signaling in Alzheimer's disease (AD), knowledge about the potential involvement of the serotonin-2B receptor (5-HTR) subtype remains sparse. Here, we assessed the levels of 5-HTRs in brain tissue from APP/PS1 transgenic (TG) mice, AD patients, and adult microglial cells. 5-HTR mRNA was measured by RT-qPCR in ageing TG and wild-type (WT) mice, in samples from the middle frontal gyrus of female, AD and control subjects, and in microglia from the cerebral cortex of WT mice.

Inflammatory bowel disease (IBD) is an idiopathic disease caused by a dysregulated immune response to host intestinal microflora. A hyperactive inflammatory and immunological response in the gut has been shown to be one of the disease's long-term causes despite the complexity of the clinical pathology of IBD. The innate immune system activator known as human gut inflammasome is thought to be a significant underlying cause of pathology and is closely linked to the development of IBD.

Postharvest processing plays a crucial role in harnessing the benefits of prickly pear fruit by utilizing betalain as natural colorants to replace artificial colors in model food systems. Prickly pear betalain-enriched gummies were developed using various sugar substitutes, including table sugar, xylitol, stevia, and fructo-oligosaccharides (FOS). These gummies were analyzed for in vitro enzymatic inhibition, anti-inflammatory effects and molecular docking studies for decoding diabetes type-II and skin resilience.

The complex pathophysiology of Alzheimer's disease (AD) poses challenges for the development of therapies. Recently, neuroinflammation has been identified as a key pathogenic mechanism underlying AD, while inflammation has emerged as a possible target for the management and prevention of AD. Several prior studies have demonstrated that medications modulating neuroinflammation might lessen AD symptoms, mostly by controlling neuroinflammatory signaling pathways such as the NF-κB, MAPK, NLRP3, etc, and their respective signaling cascade.

Article Synopsis
  • Cancer is a complex issue that requires new treatment strategies beyond traditional chemotherapy, which often has severe side effects and leads to drug resistance.
  • Essential oils (EOs), made of beneficial plant compounds, show potential as cancer-fighting agents, but their effectiveness is limited due to factors like instability and low targeted delivery.
  • Using nanoparticles and various nanosystems can improve the delivery and effectiveness of EOs in cancer treatment by enhancing absorption, controlling release, and targeting tumors more effectively.

  • Low muscle strength and function are linked to negative health outcomes in hemodialysis patients, yet reference values for muscle and physical performance tests are scarce.
  • A large-scale analysis was conducted using baseline data from the SARC-HD study, focusing on handgrip strength, sit-to-stand tests, and gait speed, with results segmented by sex and age.
  • Findings indicated that muscle strength and physical performance declined with age, with notable differences between males and females, and highlighted specific reference values that could serve as clinical markers for identifying patients at risk.

Enhancing the efficiencies of electrochemical reactions for converting renewable energy into clean chemical fuels as well as generating clean energy is critical to achieving carbon neutrality. However, this enhancement can be achieved using materials that are not constrained by resource limitations and those that can be converted into devices in a scalable manner, preferably for industrial applications. This review explores the applications of electrochemically deposited manganese dioxides (MnO) and their composites as electrochemical catalysts for oxygen evolution (OER) and hydrogen evolution reactions for converting renewable energy into chemical fuels.

In this work, two novel acridone-based photoinitiators were designed and synthesized for the free radical polymerization of acrylates with a light-emitting diode emitting at 405 nm. These acridone derivatives were employed as mono-component Type II photoinitiators and as multicomponent photoinitiating systems in the presence of an iodonium salt or an amine synergist (EDB) in which they achieved excellent polymerization initiating abilities and high final conversions of the acrylate group. Photoinitiation mechanisms through which reactive species are produced were investigated employing different complementary techniques including steady-state photolysis, steady-state fluorescence, cyclic voltammetry, UV-visible absorption spectroscopy, and electron spin resonance spectroscopy.
