PD-L1 (CD274) copy number gain, expression, and immune cell infiltration as candidate predictors for response to immune checkpoint inhibitors in soft-tissue sarcoma

OncoImmunology, 2017
Soft-tissue sarcomas (STS) are rare malignancies that account for 1% of adult cancers and comprise more than 50 entities. Current therapeutic options for advanced-stage STS are limited. Immune checkpoint inhibitors targeting the PD-1/PD-L1 signaling axis

CO2 and N2O Emissions From Vehicles in Seoul Megacity, South Korea: Insights From Mixing Ratio and Stable Isotope Ratios

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Vehicular traffic is a major source of anthropogenic greenhouse gases in megacities; however, real‐world constraints on vehicle‐derived N2O emissions and their isotopic characteristics remain limited. Methods Air samples were collected from three tunnels and urban background sites (a university campus and mountain) in Seoul, South ...

Contribution of the cyclic nucleotide gated channel subunit, CNG-3, to olfactory plasticity in Caenorhabditis elegans

Scientific Reports, 2017
In Caenorhabditis elegans, the AWC neurons are thought to deploy a cGMP signaling cascade in the detection of and response to AWC sensed odors. Prolonged exposure to an AWC sensed odor in the absence of food leads to reversible decreases in the animal’s ...

Chronic Pain as an Early Diagnostic Clue in Hereditary Multiple Exostoses: Two Pediatric Cases Highlighting Diagnostic Delay

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Hereditary multiple exostoses (HME) is a rare autosomal dominant skeletal disorder characterized by the development of multiple osteochondromas adjacent to the growth plates. Although skeletal deformities and palpable masses are common findings, chronic pain may represent an early and underappreciated diagnostic clue, particularly in pediatric
