Growth differentiation factor 11 attenuates sepsis-associated acute kidney injury by reducing inflammation and coagulation via PGC-1α/Nrf2 activation.

Background: Patients with sepsis commonly endure severe renal dysfunction and damage, hastening to end-stage renal failure with high mortality, and effective treatment options are currently lacking. Growth differentiation factor 11 (GDF11), belonging to the transforming growth factor beta (TGF-β) superfamily, has shown therapeutic potential for numerous acute and chronic inflammatory conditions. Nevertheless, its function in sepsis-associated acute kidney injury (SAKI) remains unclear.

Sarcomatoid transformation of uterine myoma identified through physical examination: a case report.

Background: Uterine myomas are the most common benign tumors in the female reproductive system. The incidence of malignant transformation within a uterine myoma is low, but once it occurs, the prognosis is usually poor. The clinical symptoms of this disease are not specific, which can easily lead to misdiagnosis or missed diagnosis.

A statistical framework for detecting therapy-induced resistance from drug screens.

Resistance to therapy remains a significant challenge in cancer treatment, often due to the presence of a stem-like cell population that drives tumor recurrence post-treatment. Moreover, many anticancer therapies induce plasticity, converting initially drug-sensitive cells to a more resistant state, e.g.

Semax peptide targets the μ opioid receptor gene Oprm1 to promote deubiquitination and functional recovery after spinal cord injury in female mice.

Background And Purpose: Lysosomal membrane permeabilization (LMP) is exacerbated following spinal cord injury (SCI), leading to increased neuronal cell death. Ubiquitination may affect LMP by regulating the stability and functionality of lysosomal membranes. Semax, a synthetic heptapeptide, comprising the ACTH (4-7) fragment and a C-terminal Pro-Gly-Pro tripeptide, exhibits neuroprotective properties and improves cognitive function.

Nanoparticles-based electrochemical sensing platform for high-through immunoassay with redox-activity CaCO nanotags on a magnetic microfluidic device.

A new nanoparticles-based sensing platform was designed for high-through electrochemical immunoassay of ferritin (FET) biomarker on a magneto-controlled microfluidic device by using anti-FET capture antibody-conjugated magnetic sensing probes. Thionine-doped calcium carbonate (CaCO) nanoparticles labeled with anti-FET detection antibodies were utilized as the recognition elements. Introduction of target FET caused the sandwich-type immunoreaction between two antibodies.

Improving soil properties and microbial communities in copper tailings using montmorillonite-based Chlorella gel beads.

Copper tailings are the waste left over from copper ore dressing, and their massive pose severe challenges to the ecosystem. In this study, sodium alginate-Chlorella-montmorillonite (SCM) gel beads were prepared by combining sodium alginate, Chlorella, and montmorillonite. The laboratory pot and in-situ field experiment results indicated that the input of SCM gel beads facilitated the formation of larger particle-size soil aggregates and enhanced soil water retention and cation exchange capacities.

Davunetide promotes structural and functional recovery of the injured spinal cord by promoting autophagy.

After spinal cord injury, programmed cell death is common. In this context, autophagy plays a crucial role in clearing cellular debris, while necroptosis exacerbates neuroinflammation and further damages neural structures. The neuroprotective drug davunetide has shown substantial therapeutic effects on brain diseases, but its role in treating spinal cord injury remains unclear.

Pectolinarin Promotes Functional Recovery after Spinal Cord Injury by Regulating Microglia Polarization Through the PI3K/AKT Signaling Pathway.

After spinal cord injury (SCI), microglia polarization plays an important role in spinal cord recovery and axon regeneration. In this study, we conducted mRNA microarrays to identify genes associated with different microglial phenotypes. The results showed a correlation between microglial polarization and the PI3K/AKT signaling pathway, a key regulator of inflammatory responses.
