The optoelectronic properties of polythiophene (PT) graft block copolymers are most important for fabricating optoelectronic devices, and recently, we reported a single-pot atom-transfer radical polymerization (ATRP) technique for preparation of PT graft block copolymers between thermoresponsive poly(diethylene glycol methyl ether methacrylate) (PDEGMEM) and pH-responsive poly(dimethyl amino ethyl methacrylate) (PDMAEMA) from the PT backbone via the "" strategy with an 11 mol % contamination. A "" strategy has been opted to eliminate the contamination from the block copolymer where we synthesized poly(thiophene acetic acid) (P3TAA) followed by the coupling with PDEGMEM--PDMAEMA-Cl, PDMAEMA--PDEGMEM-Cl, and PDMAEMA--PDEGMEM-Cl copolymers, produced separately by the ATRP technique. The polymers were characterized using H NMR, SEC, etc.

To determine the efficacy of the probiotic CECT 7347 (ES1) and postbiotic heat-treated CECT 7347 (HT-ES1) in improving symptom severity in adults with diarrhea-predominant irritable bowel syndrome (IBS-D), a randomised, double-blind, placebo-controlled trial with 200 participants split into three groups was carried out. Two capsules of either ES1, HT-ES1 or placebo were administered orally, once daily, for 84 days (12 weeks). The primary outcome was change in total IBS-Symptom Severity Scale (IBS-SSS) score from baseline, compared to placebo.

Article Synopsis
  • Cancer stem cells (CSCs) are crucial for tumor development and can evade the immune system by converting effector T cells into immunosuppressive T-regulatory cells (Tregs).
  • The study found that even a small number of CSCs could generate Tregs from CD4 T cells without direct contact, suppressing the antitumor activity of immune cells.
  • Additionally, CSCs are resistant to chemotherapy and produce high levels of the cytokine TGFβ, which promotes Treg formation, contributing to ongoing tumor growth and potential relapse after treatment.

Cancer progression is primarily caused by interactions between transformed cells and the components of the tumor microenvironment (TME). TAMs (tumor-associated macrophages) make up the majority of the invading immune components, which are further categorized as anti-tumor M1 and pro-tumor M2 subtypes. While M1 is known to have anti-cancer properties, M2 is recognized to extend a protective role to the tumor.
