The spectroscopic and dynamic properties of methyl ferulate─a naturally occurring ultraviolet-protecting filter─and microsolvated methyl ferulate have been studied under molecular beam conditions using resonance-enhanced multiphoton ionization spectroscopy in combination with quantum chemical calculations. We demonstrate and rationalize how the phenyl substitution pattern affects the state ordering of the lower excited singlet state manifold and what the underlying reason is for the conformation-dependent Franck-Condon (FC) activity in the UV-excitation spectra. Studies on microsolvated methyl ferulate reveal potential coordination sites and the influence of such coordination on the spectroscopic properties.

Objectives: This study aimed to determine thyroid hormone concentrations in a cohort of healthy kittens due to the paucity of information in the literature, and the potential for congenital hypothyroidism (CH) to contribute to fading kitten syndrome (FKS).
Methods: The serum concentrations of total thyroxine (TT4), free thyroxine (fT4), total triiodothyronine (TT3), free triiodothyronine (fT3) and thyroid-stimulating hormone (TSH) were measured in 19 healthy kittens aged 2-16 weeks.
Results: Mean TT4, fT4, TT3 and fT3 concentrations significantly differed across age groups.
Article Synopsis
- Researchers have created highly microporous carbons from pistachio shells, achieving high surface areas (up to 3300 m²/g) and pore volumes using a CO2 activation process.
- Different methods were tested to transform the biomass into carbon materials with varying structures and reactivities towards CO2, while optimizing pore development.
- The most effective technique involved hydrothermal carbonization, which boosts carbon yield and porosity, and higher activation temperatures can speed up the process without losing pore quality.
Article Synopsis
- Neuroaxonal dystrophy (NAD) is an inherited neurodegenerative disorder characterized by swollen axons in the central nervous system, with a newly identified form affecting Miniature American Shepherds.
- Clinical evaluations and genetic studies revealed that young adult dogs exhibited gait abnormalities, linked to a specific genetic mutation (a 1-bp deletion in the RNF170 gene) that follows an autosomal recessive inheritance pattern.
- The findings suggest that this canine version of NAD shares similarities with human spastic paraplegia-85, making it a potential model for studying similar human conditions and testing therapies.
The Anderson-Fabry disease (AFD) is a X-linked lysosomal storage disorder due to the deficiency in the α-galactosidase A enzyme. Cardiovascular mortality is a major cause of death in patients with AFD and sudden cardiac death (SCD) is one of the main causes of death. The storage of glycosphingolipid along with ionic channel impairment, inflammation and fibrosis are involved in the arrhythmogenesis.
