Traumatic optic neuropathy (TON) has been regarded a vision-threatening condition caused by either ocular or blunt/penetrating head trauma, which is characterized by direct or indirect TON. Injury happens during sports, vehicle accidents and mainly in military war and combat exposure. Earlier, we have demonstrated that remote ischemic post-conditioning (RIC) therapy is protective in TON, and here we report that AMPKα1 activation is crucial.

Researchers in the field of photocatalysis are interested in finding a solution to the problem of charge transfer and recombination in photodegradation mechanisms. The ideal photoactive catalyst would be inexpensive, environmentally friendly, easily manufactured, and highly efficient. Graphitic carbon nitride (g-CN) and metal oxide (MOx) based nanocomposites (g-CN/MOx) are among the photocatalysts that provide the best results in terms of charge transfer capacity, redox capabilities, and charge recombination inhibition.

Aortic dissection (AD) is a life-threatening emergency involving a tear in the aortic intima, leading to a false lumen. Atrial fibrillation (AF) can complicate AD, increasing management challenges and mortality risks. We report a 67-year-old male with no known past medical history who presented with a 1-day history of abdominal pain.

Subarachnoid hemorrhage (SAH) is the deadliest form of hemorrhagic stroke; however, effective therapies are still lacking. Perfluorocarbons (PFCs) are lipid emulsion particles with great flexibility and their much smaller size as compared to red blood cells (RBCs) allows them to flow more efficiently within the blood circulation. Due to their ability to carry oxygen, a specific PFC-based emulsion, PFC-Oxygent, has been used as a blood substitute; however, its role in cerebral blood flow regulation is unknown.

Article Synopsis
  • Lignin is a renewable biopolymer that can be transformed into valuable phenolic chemicals through depolymerization, which this study investigates using promoted Ni-based bimetallic catalysts.
  • The study compares the performance of Ni-Co/C and Ni-Cu/C catalysts supported on activated carbon to monometallic catalysts, revealing that cobalt and copper significantly boost conversion rates and yields.
  • The findings indicate that Ni-Co/C achieves the highest lignin conversion and monomer yield, suggesting its potential for efficient catalytic processes in lignin valorization.

Traumatic brain injury (TBI) is a significant public health concern characterized by a complex cascade of cellular events. TBI induces adenosine monophosphate-activated protein kinase (AMPK) dysfunction impairs energy balance activates inflammatory cytokines and leads to neuronal damage. AMPK is a key regulator of cellular energy homeostasis during inflammatory responses.

  • Zuranolone (SAGE-217) is a newly FDA-approved antidepressant for postpartum depression (PPD) and is currently being tested for its effectiveness in treating Major Depressive Disorder (MDD) and essential tremors (ET).
  • A review of four clinical trials with 1,357 patients showed that Zuranolone significantly improved depression ratings (HAM-D, MADRS, HAM-A) compared to a placebo on the 15th day of treatment.
  • While Zuranolone was associated with a higher response and remission rate, it also had a significant occurrence of treatment-emergent adverse events (TEAEs), indicating some safety concerns compared to placebo.

Traditional approaches to monitoring water quality in aquaculture tanks present numerous limitations, including the inability to provide real-time data, which can lead to improper feeding practices, reduced productivity, and potential environmental risks. To address these challenges, this study aimed to create an accurate water quality monitoring system for Asian seabass fish farming in aquaculture tanks. This was achieved by enhancing the accuracy of low-cost sensors using simple linear regression and validating the IoT system data with YSI Professional Pro.

Lignocellulosic biomass contains lignin, an aromatic and oxygenated substance and a potential method for lignin utilization is achieved through catalytic conversion into useful phenolic and aromatic monomers. The application of monometallic catalysts for lignin hydrogenolysis reaction remains one of the major reasons for the underutilization of lignin to produce valuable chemicals. Monometallic catalysts have many limitations such as limited catalytic sites for interacting with different lignin linkages, poor catalytic activity, low lignin conversion, and low product selectivity.

A set of cyclopenten-[]annelated isoindigos () has been prepared and tested for their antiproliferative activities against MCF-7 and HL60 cells. Among, the -1-methyl-5'-nitro derivative () displayed the highest activity against HL60 cells (IC = 67 nM) and acted as the most potent Flt3 inhibitor. Compounds exhibited moderate activity against MCF-7 (IC = 50-80 μM).

Driven by the urgent need for a solution to tackle the surge of rice husk (RH) and waste frying oil (WFO) waste accumulation at a global scale, this report highlights the use of calcium silicates (CS) extracted from acid-pre-treated rice husk ash (RHA) for free fatty acid (FFA) removal from WFO as conventional RHA shows limited FFA adsorption performance. A novel alkaline earth silicate extraction method from acid-pre-treated RHA was outlined. The structural and behavioural attributes of the synthesised CS were identified through BET, SEM-EDS, and XRD analyses and compared to those of RHA.

This study provides a systematic analysis of the transport and magnetophoretic behavior of nanoscale zerovalent iron (nZVI) particles, both bare and surface functionalized by poly(ethylene glycol) (PEG) and carboxymethyl cellulose (CMC), after undergoing a chemical reaction. Here, a simple and well-investigated chemical reaction of methyl orange (MO) degradation by nZVI was used as a model reaction system, and the sand column transport and low-gradient magnetophoretic profiles of the nanoparticles were measured before and after the reaction. The results were compared over time and analyzed in the context of extended Derjaguin-Landau-Verwey-Overbeek (DLVO) theory to understand the particle interactions involved.

Hydatid disease is caused by the larvae of the parasite Echinococcus granulosus and, less commonly, Echinococcus multilocularis in the endemic regions. A hydatid cyst of Echinococcus granulosus commonly develops in the liver and lungs of the affected individual and rarely occurs in the brain, bones, and heart. The spinal hydatidosis comprises 50% of the cases affecting the bones, which usually leads to severe morbidities.
