Living Materials Approach for In Situ Bio‐Polymers Production Using Bacillus Paralicheniformis in Microneedles

Advanced Healthcare Materials, EarlyView.
Dissolvable microneedle (MN) device containing Bacillus paralicheniformis. The polymeric matrix encapsulates and protects the bacteria, preserving their viability while enabling in situ production and release of γ‐polyglutamic acid. The bacteria are delivered into the skin via 500 µm‐long microneedles, and remain detectable on the skin 24 h post ...

Redefining Therapies for Drug‐Resistant Tuberculosis: Synergistic Effects of Antimicrobial Peptides, Nanotechnology, and Computational Design

Advanced Healthcare Materials, EarlyView.
Antimicrobial peptide (AMP)‐loaded nanocarriers provide a multifunctional strategy to combat drug‐resistant Mycobacterium tuberculosis. By enhancing intracellular delivery, bypassing efflux pumps, and disrupting bacterial membranes, this platform restores phagolysosome fusion and macrophage function.

K2 O/MgFe2 O4磁性固体碱催化剂的制备、表征 及催化酯交换制备碳酸甘油酯Preparation, characterisation and catalytic transesterification for the preparation of glycerol carbonate of magnetic solid base catalyst K2O/MgFe2O4

Zhongguo youzhi
为了解决生物柴油制备过程中副产物甘油过剩、碳酸甘油酯产率低和催化剂回收困难的问题，以聚乙二醇600（PEG-600）为模板和分散剂，采用溶胶凝胶法制备镁铁氧体（MgFe2O4），以其为载体，KNO3为活性组分前驱体，采用浸渍法制备K2O/MgFe2O4磁性固体碱催化剂。通过X射线衍射、 X射线光电子能谱、扫描电镜、CO2程序升温脱附(CO2-TPD)和磁性分析对催化剂进行表征，并将催化剂用于甘油与碳酸二甲酯酯交换制备碳酸甘油酯的反应中，考察其催化性能。结果表明：制备的K2O/MgFe2O4形成了K-Fe-

A new method for the separation of androgens from estrogens and for the partition of estriol from the estrone-estradiol fraction: with special reference to the identification and quantitative microdetermination of estrogens by ultraviolet absorption spectrophotometry [PDF]

, 1948
It is recognized generally that a qualitative and quantitative knowledge of the excretion pattern of the urinary estrogens is one index to an understanding of the functional activity of the ovary and adrenal cortex.

Dual‐Functional Polyphosphoesters for Gene Delivery: Synergistic Effects of Guanidinium and Hydrophobic Side Chains in Degradable Polymers

Advanced Healthcare Materials, EarlyView.
This study presents guanidinium‐ and indole‐functionalized polyphosphoesters as degradable, non‐viral gene delivery vectors. Through precise tuning of charge density and hydrophobicity, these polymers form stable polyplexes with low toxicity. Remarkably, minor structural changes yield up to 200‐fold differences in transfection efficiency, highlighting ...
