Proteolysis targeting chimeras (PROTACs) represent a transformative class of therapeutic agents that leverage the intrinsic protein degradation machinery to modulate the hemostasis of key disease-associated proteins selectively. Although several PROTACs have been approved for clinical application, suboptimal therapeutic efficacy and potential adverse side effects remain challenging. Benefiting from the enhanced targeted delivery, reduced systemic toxicity, and improved bioavailability, nanomedicines can be tailored with precision to integrate with PROTACs which hold significant potential to facilitate PROTAC nanomedicines (nano-PROTACs) for clinical translation with enhanced efficacy and reduced side effects.

Article Synopsis
  • A smartphone-assisted sensing platform using nitrogen-doped carbon dots and Rhodamine B was developed to measure ascorbic acid (AA) levels in fruits through a fluorescence quenching method.
  • The nitrogen-doped carbon dots, which emit blue light, were created using a microplasma technique and were found to have a quantum yield of 18%.
  • The system allows for both visual and quantitative measurements, achieving detection limits of 0.98 μM and 2.90 μM using fluorescence spectroscopy and a smartphone, respectively.

Xanthine oxidase (XO) is a key enzyme for the production of uric acid in the human body. XO inhibitors (XOIs) are clinically used for the treatment of hyperuricemia and gout, as they can effectively inhibit the production of uric acid. Previous studies indicated that both indole and isoxazole derivatives have good inhibitory effects against XO.

Article Synopsis
  • Dicofol, used for controlling spider mites, is chemically related to DDT, but its resistance mechanisms were unclear until now.
  • Researchers identified two genomic regions linked to resistance in the spider mite Tetranychus urticae, both containing mutations in the GluCl gene associated with resistance to other acaricides like abamectin.
  • Electrophysiology experiments showed that normal GluCl receptors respond to dicofol, while the mutated receptors effectively negate its effects, clarifying how diphenylcarbinols work specifically against these mites.

To deliver growth factors controllably for tissue regeneration, poly(aldehyde guluronate) (PAG) was obtained from alginate and covalently cross-linked with aminated gelatin (AG) to form PAG/AG hydrogel as a growth factors carrier. The prepared hydrogel exhibits a slow degradation rate and excellent cytocompatibility. Heparin was conjugated with gelatin and embedded into the hydrogel to reserve and stabilize growth factors.

Objective: To investigate the protective effects of areca nut polyphenols on hypoxic damage of rat pulmonary microvascular endothelial cells (PMVECs).

Methods: Malondialdehyde and superoxide dismutase (SOD) were used to determine the optimal modeling of lung hypoxic injury cells. CCK-8 method was used to detect cell viability for determining the effective dose of areca nut polyphenols.

Epigenetic modification refers to the heritable changes caused by chromosomal changes without changing the DNA sequence. Epigenetics runs through the entire growth and differentiation process of the body, which causes varied diseases. Hypoxia is a physiological astate of lowered partial oxygen partial pressure that affects cell and tissue function.

The plateau is a typical extreme environment with low temperature, low oxygen and high ultraviolet rays. The integrity of the intestinal barrier is the basis for the functioning of the intestine, which plays an important role in absorbing nutrients, maintaining the balance of intestinal flora, and blocking the invasion of toxins. Currently, there is increasing evidence that high altitude environment can enhance intestinal permeability and disrupt intestinal barrier integrity.

A series of -arylsulfonyl-indole-2-carboxamide derivatives have been identified as potent fructose-1,6-bisphosphatase (FBPase) inhibitors (FBPIs) with excellent selectivity for the potential therapy of type II diabetes mellitus. To explore the structure-activity relationships (SARs) and the mechanisms of action of these FBPIs, a systematic computational study was performed in the present study, including three-dimensional quantitative structure-activity relationship (3D-QSAR) modeling, pharmacophore modeling, molecular dynamics (MD), and virtual screening. The constructed 3D-QSAR models exhibited good predictive ability with reasonable parameters using comparative molecular field analysis ( = 0.

Objective: To evaluate the clinical value of quantitative tissue velocity imaging (QTVI) in detection of regional wall movement abnormalities in patients with coronary artery disease (CAD).

Methods: The segmental left ventricular wall motion velocity was measured in 45 normal subjects and 48 patients with CAD, and the parameters of QTVI were analyzed between the two groups.

Results: Velocity decrement and wave form alterations were shown in abnormal segmental movements in the CAD group.
