Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Study on Endo-B-mannanase and Ethylene in Lettuce (Lactuca sativa L.) Seed Germination Matured under Different Temperature

, 2014
'Dark Green Boston' 與 'Everglade' 30/20℃發育的種子較20/10℃發育者分別於發芽限溫27℃或33℃之發芽率較高，兩品種於30/20℃發育種子於高溫下酵素活性均高於20℃十表現，萵苣種子珠孔區胚乳或側邊胚乳於30/20℃或20/10℃發育者，所含endo-β-mannanase活性與發芽率呈正相關，胚根突出後此酵素活性大量產生。內生乙烯生合成隨發芽率增加而增加，'Dark Green Boston' 與 'Everglade' 之30/20 ...

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

European Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

The group of endo-permutation modules

The group D(P) of all endo-permutation modules for a finite p-group P is a finitely generated abelian group. We prove that its torsion-free rank is equal to the number of conjugacy classes of non-cyclic subgroups of P.

Unified Approach for the Synthesis of Close Analogues of Reverse‐Prenylated Hexahydropyrrolo Indole Alkaloids

European Journal of Organic Chemistry, EarlyView.
A simple, modular, and unified strategy for the synthesis of reverse‐prenylated hexahydropyrrolo indole alkaloids has been developed. An unusual retrosynthetic disconnection allows for the late introduction of a side chain, which distinguishes many members of this class of natural products.

Gold‐Catalyzed Cyclization of Indole‐Tethered Alkynes Enabling Synthesis of Exocyclic Alkenyl Tetrahydrocarbazoles

European Journal of Organic Chemistry, EarlyView.
An efficient gold‐catalyzed intramolecular cyclization of indole‐tethered alkynes using AgNTf2 as an additive has been developed, which provides bioactive exocyclic alkenyl tetrahydrocarbazoles with up to 85% yield. Control experiments and DFT studies indicate that the reaction proceeds via a 6‐exo‐dig cyclization pathway, with gold acetylide complexes

Production of bioethanol from residual barley and utilization of fermentation co‐products in animal nutrition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The search for sustainable alternatives for bioethanol production has encouraged the valorization of agro‐industrial residues. This study evaluated the use of residual barley as a feedstock for bioethanol production and as a potential ingredient for ruminant feed.
