Background: Neuroglobin (Ngb) and growth-associated protein (GAP) 43 in neurons are associated with axonal regeneration. Korean Red Ginseng Extract (KRGE) enhances glial fibrillary acidic protein (GFAP)-positive astrocytes and hypoxia-inducible factor-1α (HIF-1α) protein activation in normoxic astrocytes. However, crosstalk between neural stem cell (NSC) differentiation and astrocytic HIF-1α in the KRGE-treated normoxic brain and retina remains unclear.

One-lung ventilation (OLV) is crucial for collapsing the lung and improving access to the operative field during lung surgery. Intraoperative OLV may increase the intrapulmonary shunt, potentially leading to intraoperative hypoxemia. The Oxygen Reserve Index (ORI) is a continuous, noninvasive parameter that provides a broader range of oxygen reserve data than conventional oxygen saturation measurements.

Multivalent-ion batteries offer an alternative to Li-based technologies, with the potential for greater sustainability, improved safety, and higher energy density, primarily due to their rechargeable system featuring a passivating metal anode. Although a system based on the Ca/Ca couple is particularly attractive given the low electrochemical plating potential of Ca, the remaining challenge for a viable rechargeable Ca battery is to identify Ca cathodes with fast ion transport. In this work, a high-throughput computational pipeline is adapted to (1) discover novel Ca cathodes in a largely unexplored space of "empty intercalation hosts" and (2) develop material design rules for Ca-ion mobility.

Golgi abnormalities have been linked to aging and age-related diseases, yet the underlying causes and functional consequences remain poorly understood. This study identifies the interaction between age-associated zinc deficiency and Golgi stress as a critical factor in cellular aging. Senescent Golgi bodies from human fibroblasts show a fragmented Golgi structure, associated with a decreased interaction of the zinc-dependent Golgi-stacking protein complex Golgin45-GRASP55.

Article Synopsis
  • Atopic dermatitis (AD) is a chronic skin condition that causes itching and inflammation, often treated with corticosteroids like dexamethasone for temporary relief, but not as a cure.
  • Researchers explored a new non-invasive treatment called quantum molecular resonance (QMR), which showed promise in reducing AD-like skin lesions in a mouse model, minimizing immune cell infiltration and epidermal thickening.
  • Transcriptome analysis identified genes, specifically IL36G and SPRR2B, that's linked to inflammation and skin changes; QMR significantly decreased their expression, suggesting QMR could be a potential new therapy for AD.

Article Synopsis
  • Glioblastoma is described as immunologically "cold," making it resistant to solo immune-checkpoint inhibitors (ICI) like pembrolizumab, although neoadjuvant use may improve survival based on prior studies.
  • A study involving 25 additional patients analyzed tumor tissue for gene signatures and found that neoadjuvant pembrolizumab led to decreased cancer proliferation genes and increased T-cell activity, indicating a specific response to this treatment.
  • Despite observing these molecular changes, the study did not confirm an overall survival benefit from neoadjuvant pembrolizumab, suggesting that some patients may inherently resist ICI and may need additional therapies for effective treatment.

The electrochemical nitrate reduction reaction (NORR) involves multiple hydrogenation and deoxygenation steps, which compete with the hydrogen evolution reaction (HER). Therefore, NORR driven in acidic media is challenging in spite of advantageous fast hydrogen transfers in its elementary steps. The findings presented in this article first demonstrate that the NORR is significantly activated even in acidic lithium nitrate solutions at LiNO concentrations exceeding 6 m on a Pt electrode (the highly effective catalyst for HER) by the formation of a "hydronium-in-salt" electrolyte (HISE), a new type of aqueous high concentration salt electrolyte.

Elucidation of protein-protein interactions (PPIs) represents one of the most important methods in biomedical research. Recently, PPIs have started to be exploited for drug discovery purposes and have thus attracted much attention from both the academic and pharmaceutical sectors. We previously developed a sensitive method, Split Intein-Mediated Protein Ligation (SIMPL), for detecting binary PPIs via irreversible splicing of the interacting proteins being investigated.

Genomic profiling often fails to predict therapeutic outcomes in cancer. This failure is, in part, due to a myriad of genetic alterations and the plasticity of cancer signaling networks. Functional profiling, which ascertains signaling dynamics, is an alternative method to anticipate drug responses.

Higher center and surgeon volume correspond to better outcomes for patients with thyroid cancer. This study aims to investigate how a hospital's safety-net burden, the proportion of a hospital's patients who are insured by state Medicaid plans or are uninsured, influences the outcomes of high-volume (HV) surgeons. We performed a retrospective cohort study of all patients who underwent surgery for thyroid cancer in California from 1999 to 2017.

Background: Tranexamic acid (TXA) effectively attenuates hyperfibrinolysis and preemptive administration has been employed to reduce bleeding and blood transfusions in various surgical settings. However, TXA administration could be associated with adverse effects, such as seizures and thromboembolic risks. While patients with fibrinolysis shutdown showed greater thromboembolic complications and mortality, TXA administration may aggravate the degree of shutdown in these patients.
