Cyclists’ Anger As Determinant of Near Misses Involving Different Road Users

Frontiers in Psychology, 2017
Road anger constitutes one of the determinant factors related to safety outcomes (e.g., accidents, near misses). Although cyclists are considered vulnerable road users due to their relatively high rate of fatalities in traffic, previous research has ...

Transport bicycles

Proceedings of the National Academy of Sciences, 1997
Uphill transport of one substrate (the driven substrate) can be coupled to the dissipation of an electrochemical potential gradient of another substrate (the driving substrate), to an exergonic chemical reaction, or to a photoreaction. In all cases, the driven substrate is taken up from a low concentration (or relatively low electrochemical potential ...

Sappanwood extract modulates hepatic structure–function in hepatomegaly and hepcidin related iron regulatory pathways in a phenylhydrazine induced hemolytic anemia rat model relevant to thalassemia

Animal Models and Experimental Medicine, EarlyView.
Phenylhydrazine (PHZ) induces hemolytic anemia characterized by increased erythrocyte destruction and ineffective erythropoiesis, leading to hepcidin suppression through disruption of the BMP/SMAD signaling pathway. Reduced hepcidin levels enhance intestinal iron absorption and hepatic iron accumulation, leading to hepatic iron overload.

Toward the Synthesis of Pestalustaine A: Structural Revision and Formation of Original Strained Tricyclic Architectures

Angewandte Chemie, EarlyView.
Our synthetic endeavor toward the total synthesis of the reported unprecedented tricyclic skeleton of the sesquiterpene pestalustaine A allowed us to perform divergent cyclizations of a bicyclo[4.4.1]undec‐3‐ene into complex tricyclic architectures and to revise the structure of the natural product.

Dyotropic Rearrangement of Hypervalent Iodine Species: Migrative Heterofunctionalization of Quaternary Carbons

Angewandte Chemie, EarlyView.
1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...

In-depth analysis of scenarios and injuries in crashes between cyclists and commercial vehicles in Germany

Traffic Safety Research
Large vehicles such as buses and heavy goods vehicles (HGVs) pose a serious threat to cyclists and can cause serious injuries. Therefore, it is important to understand current safety issues related to these vehicles, to identify and to develop safety ...

Risk Analysis and Safer Layout Design Solutions for Bicycles in Four-Leg Urban Intersections

Safety, 2019
The road safety of vulnerable users is a current issue; in densely populated areas, the use of alternative and light mobility vehicles is growing in popularity, and their users conflict with vehicles having larger dimensions and masses.

Photochemical Ring Opening of Cyclopropyl Silyl Ethers Enables β–β Coupling, Radical‐Polar Crossover and Annulation

Angewandte Chemie, EarlyView.
A photochemical platform enables β–β coupling of cyclopropyl silyl ethers with electron‐deficient alkenes. The resulting adducts serve as entry points into annulative and radical–polar crossover pathways, providing rapid access to fused, bridged, and spirocyclic architectures, including late‐stage scaffold diversification to diterpene‐like carbocyclic ...
