Possible space mechanisms of information conversion processes with Lorenzinian ampullary apparatus during detection of the dipole electric field were studied using mathematical modelling methods. The stationary voltage distribution in the nonuniform media was calculated by numerical methods. The skate body was simulated by a thin disk. If the dipole axis lay in the disk plane potential distortions near the disk were negligibly small. In other cases the electrical field energy absorbed by ampullary groups was dramatically reduced. It is supposed that body tissues serve as a space filter of the electroreceptive system.

Differences in habitat use impose ecological constraints which in turn lead to functional and morphological differences through adaptation. In fact, a convergent evolutionary pattern is evident when species exhibit similar responses to similar environments. In this study we examine how habitat use influences the evolution of body shape in lizards from the family Lacertidae.

Exercise provides health benefits to multiple metabolic tissues through complex biological pathways and interactions between organs. However, investigating these complex mechanisms in humans is still limited, making mouse models extremely useful for exploring exercise-induced changes in whole-body metabolism and health. In this review, we focus on gaining a broader understanding of the metabolic phenotypes and molecular mechanisms induced by exercise in mouse models.

Background: Explantation often alleviates symptoms in women with breast implant illness. However, persistent complaints in some cases may be linked to persistent silicone-induced inflammation from residual silicone particles. Positron emission tomography (PET) imaging could potentially detect this inflammation.

Background: Metabolic cardiomyopathy is characterized by structural and functional changes to the heart and interstitial fibrosis without coronary artery disease or hypertension. Inborn metabolic defects are a common cause of cardiomyopathy in children. There are more than 40 kinds of inborn metabolic defects that cause cardiomyopathy.

Background: Acromiohumeral interval (AHI) reversibility is used to evaluate whether superior humeral migration is fixed or flexible in patients with massive rotator cuff tears (MRCTs). AHI reversibility is measured as the difference in the AHI observed between standard and stress radiography. However, factors affecting AHI reversibility have not been studied in the existing literature.
