Predictive markers of response to immune checkpoint inhibitor rechallenge in metastatic non-small cell lung cancer.

Aim: The present study aims to evaluate the efficacy of rechallenge with immune checkpoint inhibitors (ICIs) compared to chemotherapy and the predictive role of clinical parameters in non-small cell lung cancer (NSCLC) patients who were rechallenged.

Methods: The study included 113 metastatic NSCLC patients who had initially responded to ICIs and platinum-based chemotherapy, either in combination in the first line or sequentially in the first and second line, but later experienced disease progression. Of those patients, 52 later received ICI rechallenge and 61 were exposed to chemotherapy.

Capmatinib in MET exon 14-mutated non-small-cell lung cancer: final results from the open-label, phase 2 GEOMETRY mono-1 trial.

Background: Capmatinib has previously shown activity in treatment-naive and previously treated patients with non-small-cell lung cancer (NSCLC) and a MET exon 14-skipping mutation (METex14). Here, we report the final outcomes from the phase 2 GEOMETRY mono-1 study with an aim to provide further evidence for the activity of capmatinib.

Methods: In this non-randomised, multi-cohort, open-label, phase 2 trial conducted in 152 centres and hospitals in 25 countries, with patients treated in 95 centres in 20 countries, eligible patients (aged ≥18 years) with MET-dysregulated, EGFR wild-type, and ALK rearrangement-negative advanced NSCLC (stage IIIB/IV) and an Eastern Cooperative Oncology Group performance status of 0 or 1 were assigned to cohorts (1a, 1b, 2, 3, 4, 5a, 5b, 6 and 7) based on their MET status (METex14 or MET amplification) and previous therapy lines.

The Structure and Optical Properties of Luminescent Europium Terephthalate Antenna Metal-Organic Frameworks Doped by Yttrium, Gadolinium, and Lanthanum Ions.

New heterometallic antenna terephthalate MOFs, namely, (EuM)bdc·4HO (M = Y, La, Gd) (x = 0.001-1), were synthesized by a one-step method from aqueous solutions. The resulting compounds are isomorphic to each other; the crystalline phase corresponds to Lnbdc∙4HO.

Current status of molecular diagnostics for lung cancer.

The management of lung cancer (LC) requires the analysis of a diverse spectrum of molecular targets, including kinase activating mutations in , (), and oncogenes, G12C substitutions, and , , and gene fusions. Administration of immune checkpoint inhibitors (ICIs) is based on the immunohistochemical (IHC) analysis of PD-L1 expression and determination of tumor mutation burden (TMB). Clinical characteristics of the patients, particularly age, gender and smoking history, significantly influence the probability of finding the above targets: for example, LC in young patients is characterized by high frequency of kinase gene rearrangements, while heavy smokers often have G12C mutations and/or high TMB.

Response to trametinib, hydroxychloroquine, and bevacizumab in a young woman with -mutated metastatic intrahepatic cholangiocarcinoma: a case report.

Systemic chemotherapy is the main treatment option for patients with advanced intrahepatic cholangiocarcinoma (iCCA), however, its efficacy is limited. Herein, we report a young patient with -mutated chemoresistant metastatic iCCA, who received second-line therapy with a combination of trametinib (MEK1/2 inhibitor), hydroxychloroquine (autophagy inhibitor), and bevacizumab (angiogenesis inhibitor). A significant response was achieved during therapy, resulting in a 25% decrease in the size of tumor lesions after 2 months of treatment and an improvement in the patient's condition.

In this work, three series of micro-sized heterometallic europium-containing terephthalate MOFs, (EuLn)bdc·nHO (Ln = La, Gd, Lu), are synthesized via an ultrasound-assisted method in an aqueous medium. La and Gd-doped terephthalates are isostructural to Eubdc·4HO. Lu-doped compounds are isostructural to Eubdc·4HO with Lu contents lower than 95 at.

Neural population dynamics reveals disruption of spinal circuits' responses to proprioceptive input during electrical stimulation of sensory afferents.

While neurostimulation technologies are rapidly approaching clinical applications for sensorimotor disorders, the impact of electrical stimulation on network dynamics is still unknown. Given the high degree of shared processing in neural structures, it is critical to understand if neurostimulation affects functions that are related to, but not targeted by, the intervention. Here, we approach this question by studying the effects of electrical stimulation of cutaneous afferents on unrelated processing of proprioceptive inputs.

Thyroid Dysfunction and Cardiovascular Events in Patients With Dysglycemia.

Objectives: Subclinical thyroid disease is the most common form of thyroid dysfunction and may be associated with adverse cardiovascular outcomes in people at high risk for cardiovascular events. Our objective in this study was to assess the association of thyroid function and thyroid hormone replacement with cardiovascular outcomes in high-risk individuals with dysglycemia and additional cardiovascular risk factors.

Methods: The relationship between baseline thyrotropin (TSH) level and incidence of the composite outcome of nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death; an expanded composite of this outcome plus revascularization or hospitalization for heart failure; and mortality was assessed in 8,401 ORIGIN trial participants with a baseline measurement of TSH.

Accelerating Airy beams with particle-like polarization topologies and free-space bimeronic lattices.

Phase and polarization singularities in electromagnetic waves are usually attributed to one-dimensional topologies-lines, knots, and braids. Recently, particle-like structures have been predicted and observed: optical Skyrmions, vortices with spherical polarization, etc. In this article, we devise vector Airy beams with point-like singularity in the focal plane, thus leading to the presence of a particle-like topology.

Coherent Anti-Stokes Raman Scattering Measurements of Time and Length Scales of Temperature Fluctuations in a Turbulent Flame.

The ability to derive temporal and spatial scales of "instantaneous" local temperature variations in a turbulent flame by means of coherent anti-Stokes Raman scattering (CARS) spectroscopy is demonstrated, for the first time to our knowledge. The measurements employed two CARS spectrometers with synchronized nanosecond pulse-repetitive lasers. The system was enabling to record, with a high temporal resolution of about 10 ns, series of single laser shot CARS spectra of N molecules from two spatially overlapped or displaced probe volumes as small as 0.

Keeping rhesus monkeys as laboratory animals requires timely prevention and treatment of infections, including diseases of bacterial etiology. Based on our own studies of the microflora of healthy and sick monkeys, as well as analysis of published reports, we identified clinically significant representatives of pathogenic and opportunistic bacteria: E. coli, Staphylococcus aureus, Klebsiella spp.

Electrochemical Sensors for Controlling Oxygen Content and Corrosion Processes in Lead-Bismuth Eutectic Coolant-State of the Art.

Controlling oxygen content in the primary circuit of nuclear reactors is one of the key tasks needed to ensure the safe operation of nuclear power plants where lead-bismuth eutectic alloy (LBE) is used as a coolant. If the oxygen concentration is low, active corrosion of structural materials takes place; upon increase in oxygen content, slag accumulates due to the formation of lead oxide. The generally accepted method of measuring the oxygen content in LBE is currently potentiometry.

Adiponectin Stimulates Apolipoprotein A-1 Gene Expression in HepG2 Cells via AMPK, PPARα, and LXRs Signaling Mechanisms.

Adiponectin is an adipose tissue hormone, participating in energy metabolism and involved in atherogenesis. Previously, it was found that adiponectin increases expression of the APOA1 (apolipoprotein A-1) gene in hepatocytes, but the mechanisms of this effect remained unexplored. Our aim was to investigate the role of adiponectin receptors AdipoR1/R2, AMP-activated protein kinase (AMPK), nuclear peroxisome proliferator-activated receptor alpha (PPARα) and liver X receptors (LXRs) in mediating the action of adiponectin on hepatic APOA1 expression in human hepatoma HepG2 cells.

Background: Adiponectin (AN) is a protein synthesized by adipocytes that has regulatory effects on lipid and lipoprotein metabolism, increases tissue sensitivity to insulin, and modulates endothelial functions and inflammatory response. However, its involvement in the processes of atherogenesis remains poorly understood.

Objective: To determine the localization and sources of AN in atherosclerotic and normal human aortic intima.

Terahertz structured light: nonparaxial Airy imaging using silicon diffractive optics.

Structured light - electromagnetic waves with a strong spatial inhomogeneity of amplitude, phase, and polarization - has occupied far-reaching positions in both optical research and applications. Terahertz (THz) waves, due to recent innovations in photonics and nanotechnology, became so robust that it was not only implemented in a wide variety of applications such as communications, spectroscopic analysis, and non-destructive imaging, but also served as a low-cost and easily implementable experimental platform for novel concept illustration. In this work, we show that structured nonparaxial THz light in the form of Airy, Bessel, and Gaussian beams can be generated in a compact way using exclusively silicon diffractive optics prepared by femtosecond laser ablation technology.
