RETROSPECTIVE ANALYSIS OF DYSHORMONGENETIC GOITRE [PDF]

open access: yes, 2012
Dyshormonogenetic goitre is a rare thyroid entity which occurs due to enzymatic deficiency in the physiological process of thyroxin synthesis resulting in goitre formation. This has to be differentiated from iodine deficiency goitres for their similarity

It's a Gas: Bioconjugation With Vapor‐Phase Reagents

open access: yesChemistry – A European Journal, EarlyView.
Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

Copper‐ and Silver‐Catalyzed Reactions of Active Methylene Isocyanides: Facile Access to Highly Substituted Five‐ and Six‐Membered Heterocycles

open access: yesChemistry – A European Journal, EarlyView.
This review summarizes recent advances in copper‐ and silver‐catalyzed reactions of active methylene isocyanides for the synthesis of highly substituted five‐ and six‐membered heterocycles. Emphasis is placed on [3+n] cycloadditions, annulations, and asymmetric strategies, highlighting current limitations and future opportunities in heterocycle ...

Polymerizable disilanols having in-chain perfluoroalkyl groups [PDF]

open access: yes, 1973
Disilanols containing in-chain perfluoroalkyl and aromatic groups and the process by which they were prepared are discussed. The disilanols, when reacted with a diaminosilane and cured, produce polymeric material resistant to hydrocarbon fuels and stable

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy

open access: yesChemistry – A European Journal, EarlyView.
Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.

Tuning the Growth Pattern of Triangular Silver Nanoplates from Lateral to Vertical by Secondary Metal Addition

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
What happens, if in the synthesis of flat silver platelets, the slow deposition of silver along twinning faults is disturbed by the addition of a nobler metal? We have looked into it and found a way to fine‐tune the metal deposition in lateral and vertical direction.

Evaluation of Different Detection and Identification Methods of Intact Tetrahydro‐Methyltestosterone Sulfate Metabolites in Doping Control

open access: yesDrug Testing and Analysis, EarlyView.
The micro‐scale synthesis of the six out of eight possible tetrahydro‐methyltestosterone sulfate metabolites was performed, and the synthesized materials were used as analytical standards. The analysis of post‐administration sample extracts from methyltestosterone excretion studies against these standards provides further experimental proof for their ...
