Clinical characteristics of ALK-positive NSCLC patients treated with sequential ALK-TKI therapies in a single-centre.

Fujita Kohei K, Imakita Takuma T, Fujimoto Naoki N, Yoshimura Saiki S et al.

Although sequential treatment with ALK-TKIs for ALK-positive lung cancer is commonly practiced in clinical settings, there are few reports on the actual treatment choices, efficacy and safety. This retrospective study evaluated the treatment sequence, progression-free survival (PFS), overall survival (OS), and adverse events (AEs) for the patients who received two or more ALK-TKIs. Eleven patients were included in the study. The median age was 59 years, and five patients (45.5%) were female. The number of ALK-TKIs administered was two in five patients, three in five patients, and four in one patient. The drugs used were Alectinib in 10 patients, Lorlatinib in eight, Brigatinib in six, Ceritinib in three, and Crizotinib in two. Six patients (54.5%) had a history of treatment with cytotoxic chemotherapy in addition to ALK-TKIs. The most common first-line drug was Alectinib, followed by Brigatinib and Crizotinib. The median PFS for each treatment line was 23 months for the first line, 17 months for the second, 14 months for the third, and 5 months for the fourth. The median OS from 1st ALK-TKI was 58 months. Discontinuation of ALK-TKI due to adverse events occurred in six of the total treatment cases, and five of these (83.3%) were attributed to Brigatinib. Sequential treatment with different types of ALK-TKIs demonstrated a certain degree of efficacy. However, the incidence of discontinuation due to adverse events was higher for Brigatinib than for other ALK-TKIs.

Systematic Targeting of Protein Complexes with Molecular COUPLrs.

Yang Diane D, Harry Stefan Andrew SA, Chong Harrison Byron HB, Khandelwal Neha N et al.

Small molecules that modulate protein complexes have transformed cell biology and oncology, yet few chemical starting points exist to probe protein-protein interactions. To expand this space, we developed molecular COUPLrs, elaborated small molecules flanked by two cysteine‑reactive warheads. Using CONNECT, an integrated chemical proteomic platform that identifies proteins and complexes amenable to coupling, we revealed 171 targetable protein classes, including mutant‑selective complexes and assemblies not traditionally addressed by small molecules. We then optimized a COUPLr against the oncogenic fusion EML4‑ALK. This compound engages EML4‑ALK by binding its EML4 domain, remodeling protein dynamics, disrupting downstream signaling, and inducing proteasome‑mediated degradation of the fusion. Finally, we show that FDA‑approved drugs can be converted into COUPLrs to degrade their targets, indicating that this modality can endow existing therapeutics with new functional properties. Overall, molecular COUPLrs offer an unbiased framework to discover, characterize, and pharmacologically exploit protein complexes.

Investigating the Performance of Asphalt Modified with Rubber Powder and Surface Organic Layered Double Hydroxides.

Fang Chenze C, Guo Xu X, Chen Yuanzhao Y, Li Zhenxia Z et al.

In order to promote the sustainable development of road engineering, this study used waste tire rubber powder (RP) and surface organic layered double hydroxide (SOM-LDHs) to modify 70# matrix asphalt. The Box-Behnken design response surface method with three factors (rubber powder content, surface organic layered double hydroxide content, shear temperature) and three responses (penetration, ductility, softening point) was used to optimize the preparation parameters. The optimum formula was determined to be 21.7% rubber powder content, 4.8% surface organic layered double hydroxide content, and 160 °C shear temperature. The effect of the modifier on the surface morphology was analyzed using a rotating film oven test and ultraviolet aging test. The high and low temperature rheological properties of asphalt were evaluated by dynamic shear rheometer (DSR), bending beam rheometer (BBR), and the multi-stress creep recovery test (MSCR). The microstructure was observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The aging mechanism was investigated by Fourier transform infrared spectroscopy (FTIR) and gel permeation chromatography (GPC). The results show that after aging, the complex shear modulus of rubber powder/surface organic layered double hydroxide composite modified asphalt is the highest, which is 27.35% higher than that of matrix asphalt. The rutting factor reaches 79.86 kPa at 46 °C, the phase angle decreases by 11.83% after UV aging, and the high temperature plastic deformation resistance is the best. In the low temperature range of -18 °C to -24 °C, the creep stiffness of the composite modified asphalt is about 30% lower than that of the matrix asphalt, while the m value is increased by about 15%, and the low temperature stress relaxation performance is significantly improved. The strain recovery rate of composite modified asphalt under 3.2 kPa stress reaches 78.5%, and the unrecoverable creep compliance is as low as 0.18 kPa-1, which is better than that of matrix asphalt and single rubber powder modified asphalt.

Humic Acid Recovery from Leachate Nanofiltration Concentrate Using Halloysite Nanotube-Coated Tubular Ceramic Ultrafiltration Membrane.

Akarçay Demir Sultan S, Varank Gamze G, Koseoglu-Imer Derya Y DY, Arslan Cene Gülay G et al.

Landfill wastewater is a serious environmental problem and represents a high-concentration source of valuable organic compounds such as humic acids (HAs). The nanofiltration (NF) concentrate generated during treatment poses an even more significant environmental challenge, and the recovery of these substances is compatible with circular economy principles but requires innovative, pollution-resistant separation technologies. This study presents a novel hybrid approach for HA recovery by integrating naturally occurring clay minerals, such as halloysite nanotubes (HNTs), as a dynamic coating layer onto tube-shaped ceramic ultrafiltration membranes. The research was conducted in two stages: batch adsorption-desorption experiments followed by membrane integration. In the first stage, the batch adsorption studies showed that HA adsorption by HNTs followed the Freundlich isotherm model. The maximum HA adsorption capacity for HNTs increased with increasing initial concentration. In desorption studies, recovery rates of 74.6% were achieved with 1.5 N sodium hydroxide (NaOH) and 67.5% with 1.5 N potassium hydroxide (KOH). In membrane studies, the optimum HNT coating concentration was determined as 0.05 g/L. While an average removal efficiency of 85.3% was obtained in synthetic HA filtration, the desorption efficiency after regeneration was around 35-37%. In experiments with real NF concentrate, HA removal efficiencies ranged from 19 to 64% for concentrations of 5, 10, and 20 mg/L, with the highest desorption efficiency (59.3%) obtained in the 10 mg/L NF concentrate. The results reveal that the complex structure and competing components in the real wastewater matrix limit the removal and recovery performance compared to synthetic solutions.

Transient Ischemic Attack-Like Presentation of Extensive Cerebral Venous Thrombosis in a Child With Anaplastic Large Cell Lymphoma.

Cherrabi Chaymae C, Azizi Manal M, Bennani Amal A, Kamaoui Imane I et al.

Cerebral venous sinus thrombosis (CVST) is a rare but serious cerebrovascular complication in children, particularly in the setting of malignancy. We report a case of a 12-year-old boy with anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma who developed extensive CVST shortly after initiation of chemotherapy. He presented with a transient neurological episode characterized by limb heaviness and dysarthria, initially suggestive of a transient ischemic attack, with complete spontaneous recovery. Although the clinical context raised concern for treatment-related complications, neuroimaging was essential for diagnosis, and magnetic resonance venography confirmed extensive CVST. The patient was treated with anticoagulation using low-molecular-weight heparin, followed by rivaroxaban, with continuation of chemotherapy under close monitoring. Clinical and radiological outcomes were favorable, with complete recanalization after nine months and no neurological sequelae. This case underscores the importance of early recognition of CVST in pediatric oncology patients with atypical neurological symptoms and the pivotal role of prompt neuroimaging.

Understanding the stability of the solid electrolyte interphase formed by vinylene carbonate and fluoroethylene carbonate in sodium-ion batteries.

Schuster Jan Felix JF, Hu Qihan Q, King Laura L, Lapidus Alexandre Linas AL et al.

The formation of a stable solid electrolyte interphase (SEI) in sodium-ion batteries is a challenge which is usually solved by introducing film-forming electrolyte additives. The functions and decomposition of common additives like vinylene carbonate (VC) and fluoroethylene carbonate (FEC) are not fully understood and yield different results in full- and half-cells. This study reveals that the electrochemical reduction of an electrolyte solution based on 1 M NaPF6 dissolved in ethylene carbonate and diethyl carbonate (EC : DEC) with no additive yields a lower charge loss, while electrolytes containing 2 wt% VC or FEC additives suffer from higher charge consumption for the formation and reformation of SEI due to higher solubility. To solely investigate stability and dissolution of the SEI in the absence of other ageing mechanisms, a model cell consisting of a carbon-coated aluminium foil working electrode and Prussian white counter and reference electrodes was used. Additionally, the experiments show a detrimental effect from using sodium metal counter electrodes. This work sheds light on the insufficiency of VC and FEC electrolyte additives in forming a perfect SEI. However, further investigations are required to account for additional ageing mechanisms to provide a comprehensive understanding of the role of VC and FEC in practical sodium-ion batteries.
