Multifunctional polycaprolactone‐based composite fibers with icariin and glutathione for effective repair of critical‐sized bone defects

open access: yesBMEMat, EarlyView.
A multifunctional PCL‐based scaffold co‐delivering Icariin and Glutathione synergistically enhances osteogenesis, angiogenesis, and oxidative stress resistance, achieving near‐complete repair of critical‐sized bone defects in vivo. This cell‐free platform represents a promising strategy for accelerated bone regeneration.

The Determination of Methimazole by Infrared Spectrophotometry

open access: yesJournal of AOAC INTERNATIONAL, 1965
Abstract A method for the determination of methimazole by column chromatography and infrared spectrophotometry was subjected to collaborative study in four district laboratories. Although the results were favorable, they were not sufficiently precise nor accurate to recommend the method for adoption.

Exosome‐mimetic vesicle‐encapsulated multi‐responsive antibacterial hydrogel core‐shell microneedle patch promotes scarless healing of infected wounds

open access: yesBMEMat, EarlyView.
The core‐shell microneedle patch VP@FNV‐CuO2‐MN was fabricated by encapsulating n‐CuO2 in a moderately crosslinked PVA/CMCS/Borax4 hydrogel shell and VP‐loaded fibroblast membrane nanovesicles (VP@FNV) in a highly crosslinked PVA/CMCS/Borax6 hydrogel core. Upon application to an infected wound, the acidic microenvironment triggers Fenton‐like reactions

Naturally occurring epoxy acids: ii. detection and measurement of long-chain epoxy acids by near infrared spectrophotometry*†

open access: yesJournal of Lipid Research, 1961
A new method for the detection and estimation of long-chain epoxy acids in seed oils is described. It depends on the measurement of increased absorption at 2.795 μ in the near infrared spectrum caused by chlorohydrins produced from epoxides by treatment ...

Detection of Solvents by Infrared Spectrophotometry

open access: yesJournal of AOAC INTERNATIONAL, 1967
Abstract The solvent used in the recrystallization of a solid may be determined by use of the IR spectrum and gas cell. Recrystallized powders retain a minute amount of solvent which is not detectable in a KBr disk of the powder, but is detectable when a gas cell is vised.

Probiotic spore‐based bioresponsive drug delivery for reversing inflammatory bowel disease and its associated anxiety and depression

open access: yesBMEMat, EarlyView.
A probiotic spore‐based drug delivery system (BCS‐Que@ApNPs) provides excellent targeted delivery, bioresponsive drug release, and long‐term retention (over 48 h), making it suitable for oral treatment of inflammatory bowel disease and its associated anxiety and depression.

Gallstone analysis by infrared spectrophotometry

open access: yes, 1982
의학과/석사[한글] 담석 분석은 1863년 Thudichum이 최초로 담석의 외형적상태에 따라 분류한 이레 여러번의 수정을 거쳐왔다. 담석의 분석은 그 성분이 담즙색소와 무기질을 함유하고 있기 때문에 어려운 점이 많다. 분석방법으로는 Stepwise solvent extraction method, X-ray diffr action method, thin layer chromatography, 그리고 Infrared spectrophotometry ...
