Transition-metal catalyzed synthesis of Ketoprofen

Journal of the Brazilian Chemical Society, 2000
Transition metal-catalyzed reactions including carbonylations, hydrovinylations and hydrogenations have been applied in the synthesis of alpha-(3-benzoylphenyl)propanoic acid (Ketoprofen). 3-Vinylbenzophenone was obtained from 3-bromobenzophenone by a Pd-

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I

International Journal of Cosmetic Science, EarlyView.
Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed

Physicochemical Quality and Chemical Safety of Commercial Wet Cat Food: Composition, Oxidation, Biogenic Amines, and Trace Elements

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study investigated the physicochemical characteristics and chemical safety of commercial wet cat foods marketed in Brazil. Twenty products labeled as beef, chicken and fish flavors were analyzed for proximate composition, pH, lipid and protein oxidation, biogenic amines, and essential and potentially toxic trace elements.

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

Physiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Heat treatment combined with hybrid exercises retraining mitigates cellular markers of protein turnover after hindlimb suspension in male mice: A pilot study

Experimental Physiology, EarlyView.
Abstract Recent evidence suggests that heat treatment (HT) and resistance training can limit skeletal muscle mass loss during immobilization. However, the effects of repeated HT sessions combined with hybrid exercises (EX), which promote both endurance and resistance responses, on muscle protein turnover following hindlimb unloading (HU) remain ...
