Summary: Using self-consistent field theory, the phase boundaries between periodic microphases for linear, comb-like, and bottlebrush diblock copolymers were mapped, revealing a universal phase diagram for sphere phases including A15 and sigma phases. However, a transition from comb-like to bottlebrush scaling with architectural parameter variation was not observed.

Summary: A study compared the biological reactions and phenomena induced by a bioresorbable poly (L-lactic acid) flow diverter (PLLA-FD) with a metallic flow diverter (CoCr-FD) for the treatment of intracranial aneurysms. The results showed no significant differences between PLLA-FD and CoCr-FD in terms of aneurysm occlusion and branch patency. The local inflammation and neointima thickness of PLLA-FD over a 1-year period were also similar to those of CoCr-FD.

Summary: High-pressure homogenization improved the foaming properties of insoluble pea proteins at pH 3 and 5. At pH 3, the homogenization disrupted large protein aggregates into smaller particles, resulting in the generation of foams. At pH 5, homogenization resulted in the formation of aggregates made of smaller protein entities, allowing insoluble pea proteins to foam.

Summary: The inadequate understanding of the structure-activity relationship (SAR) of glycosite-specific antibody-drug conjugates (ADCs) hinders its design and development. In this study, we constructed and examined 50 gsADC structures with various glycan subtypes and linker-drug combinations to reveal the systematic SAR and structure-toxicity relationship (STR) of gsADCs. Our findings suggest that the use of extra hydrophilic linkers is crucial for intact glycan-based gsADCs to improve in vivo efficacy. Additionally, gsADCs that conjugate linker-drug complexes onto the terminal sialic acid demonstrate greater stability and potency compared to those conjugated onto the terminal galactose. Moreover, LacNAc-based gsADCs, which adopt a shorter spacer and locate the linker-drug more inside the immunoglobulin class G (IgG) Fc cavity, exhibit excellent hydrophilicity, in vivo activity, pharmacokinetics, and safety. Overall, we found that concealing the linker-toxin within the Fc cavity can significantly enhance the therapeutic index of LacNAc-based gsADCs, facilitating the design of ADCs with optimal druggability.

Summary: The quality of active pharmaceutical ingredients (APIs) is crucial for the safety and efficacy of pharmaceuticals. This study found that different crystallization processes of paliperidone palmitate (PP) can impact the appearance, surface free energy (SFE), and crystallinity of PP, consequently affecting the stability, state, and pharmacokinetics of formulations in vivo. Therefore, the choice of crystallization methods for preparing APIs can have significant implications on the overall performance of pharmaceutical formulations.

Summary: The development of a thermo-sensitive triblock copolymer composed of BSA protein has shown promising potential in wound healing and tissue regeneration. The bioconjugate gel exhibited good adhesive properties to major organs and promoted rapid wound contraction, increased angiogenesis, and collagen deposition compared to controls in in vivo trials. These biocompatible, biodegradable, and thermos-sensitive bioconjugate gels may offer a new approach for wound healing without the need for additional biofactors or inorganic nanoparticles.

Summary: PT-enhanced Fenton-based CDT is a promising cancer treatment approach that triggers the Fenton or Fenton-like reactions within the tumor microenvironment to generate highly cytotoxic hydroxyl radicals. However, existing CDT therapies are hindered by limitations such as low levels of endogenous hydrogen peroxide and low catalytic efficacy, prompting the combination of photothermal therapy (PTT) to enhance therapeutic efficacy.
