Treatment-related skin reactions in enfortumab vedotin as a surrogate marker of survival and treatment response.

Background: Treatment-related skin reactions (TRSRs) induced by enfortumab vedotin (EV) targeting nectin-4 are among the most common adverse events. However, their association with survival and treatment response is poorly understood.

Methods: We retrospectively identified patients who received EV from December 2021 to April 2023 at Nagoya University Hospital and its affiliated facilities and extracted clinical data from their medical records.

Molecular structure of enzyme-synthesized amylose-like chimeric isomaltomegalosaccharides and their encapsulation of the sulfasalazine prodrug.

The glucoconjugation between linear chimeric α-(1→4)- and α-(1→6)-glucosidic segments exhibits functional properties throughout their structure. In this study, we enzymatically synthesized three new series of chimeric nonreducing isomaltomegalosaccharides (N-IMS-n/m), each featuring a constant n, α-(1→4)-segment (average degree of polymerization, DP = 22-25) at the nonreducing terminal, and varying m, α-(1→6)-main chain lengths (DP = 7-53). The synthesized compounds-N-IMS-25/7, N-IMS-24/19, and N-IMS-22/53-were compared to amylose (DP = 28) and previous samples of N-IMS-15/35 and D-IMS-28.

Synthetic retinoid-mediated preconditioning of cancer-associated fibroblasts and macrophages improves cancer response to immune checkpoint blockade.

Background: The proliferation of cancer-associated fibroblasts (CAFs) hampers drug delivery and anti-tumor immunity, inducing tumor resistance to immune checkpoint blockade (ICB) therapy. However, it has remained a challenge to develop therapeutics that specifically target or modulate CAFs.

Methods: We investigated the involvement of Meflin cancer-restraining CAFs (rCAFs) in ICB efficacy in patients with clear cell renal cell carcinoma (ccRCC) and urothelial carcinoma (UC).

Fucoidan from brown seaweed Tubinaria decurrens: Structure and structure - anticancer activity relationship.

The aims of this study are to determine the structure of a fucoidan from brown seaweed Turbinaria decurrens, to investigate its anticancer activity and structure-activity relationship. SEC-MALLS, IR, ESI-MS and NMR spectra analysis indicated that dominant structure of the fucoidan, with a Mw 122.6 KDa, has a backbone of (1 → 3)- and (1 → 4)-α-L-Fucp residues, branched at C-4, sulfate groups are attached at C-2, C-3 and C-4; branches are (1 → 4)-β-D-Galp residues and sulfated at C-2.

The relaxation effect of autonomous sensory meridian response depends on personal preference.

Background: Autonomous sensory meridian response (ASMR) is a sensory response such as tingling and pleasantness from audiovisual stimuli. ASMR videos come in a wide variety of types, and personal preferences are biased. There are many reports of the effects os ASMR on sleep onset, anxiety relief, and other relaxation effects.
