Background: Positive pressure ventilation (PPV) is an essential component of neonatal resuscitation. Meta-analytic evidence suggests that, among late preterm and term newborn infants who require resuscitation after birth, a supraglottic airway (SA) device is more effective than a face mask at reducing the probability of PPV failure and reducing the need for endotracheal intubation. However, SA devices are rarely used in routine practice in hospital delivery room settings within the United States.

Effective cancer therapy aims to treat primary tumors and metastatic and recurrent cancer. Immune checkpoint blockade-mediated immunotherapy has shown promising effects against tumors; however, its efficacy in metastatic or recurrent cancer is limited. Here, based on the advantages of nanomedicine, lipid nanoparticles (LNPs) that can target tumors are synthesized for photothermal therapy (PTT) and immunotherapy to treat primary and metastatic recurrent cancer.

  • The introduction of immune checkpoint blockade (ICB) has greatly improved treatment outcomes for advanced melanoma, but many patients still become resistant to it due to unclear reasons.
  • Although combining different ICB therapies has been shown to enhance response rates, it also comes with increased toxicity for patients.
  • An analysis of tumor samples from ICB-naïve patients revealed that high genomic heterogeneity and low ploidy can identify those who are intrinsically resistant to aPD-1, leading to a predictive model that may help tailor treatment strategies.

encodes the alpha subunit of the heterotrimeric Go protein. Despite being the most abundant G protein at synapses, the role of Go in the brain remains unclear, primarily because of the high mortality associated with developmental and epileptic encephalopathy (DEE) 17 in mutated animals. Here, we conducted proteomic analyses with a brain synaptosomal fraction to investigate the Go-interactome and then generated a non-DEE model using mice to selectively knockout (KO) the presynaptic Gαo within cerebellum.

Periocular and orbital myiasis are rare, vision-threatening conditions characterized by the infestation of dipterous fly larvae into periorbital and orbital tissues. While it has been primarily reported in tropical and subtropical regions where the climate is ideal for fly larval breeding, any patient with inadequate wound care regardless of geography may be predisposed. Infestations can progress rapidly over the course of several days with significant risk of life-threatening intracranial extension.

Liquid marbles (LMs) are microliter-scale droplets coated with hydrophobic solid particles. The particle size and hydrophobicity of the surface coating determine their properties, such as transparency, expandability, and resistance to evaporation and coalescence, one or more of which can be critical to their application as microreactors. This study reports the use of a mixture of two different hydrophobic powders for fabrication of LMs for colorimetric assays: trichloro(1,1,2,2-perfluorooctyl) silane-linked silica gel (modified silica gel (MSG), particle size: 40-75 μm) and hexamethyldisilazane-linked fumed silica (modified fumed silica (MFS), average aggregate length: 200-300 nm).

Article Synopsis
  • Malignant glioma, a deadly brain cancer, creates an immunosuppressive environment that limits the effectiveness of treatments targeting the immune system.
  • Researchers used single-cell RNA sequencing to identify glioma cells expressing CD83, a marker linked to mature immune cells, and studied its effects on tumor growth and immune response in mice and human samples.
  • Findings indicate that CD83+ tumor cells may promote anti-tumor activity by enhancing T cell responses and increasing inflammatory signals, suggesting that CD83 could be a potential target for improving immunotherapy in glioma patients.

Background: Heightened levels of inflammatory markers are linked to increased morbidity/mortality in people with HIV (PWH) and often remain elevated after virologic suppression by antiretroviral therapy (ART). As new combinations of ART become available, an evaluation of their effects on immune activation and inflammation is warranted. Additionally, it remains unknown whether transient increases in viral load ("blips") during ART are associated with increases in inflammation.
