A piezoelectric body film of the present invention is a piezoelectric body film containing a perovskite-type oxide represented by Formula (1), in which a content q of Nb with respect to the number of all atoms in the perovskite-type oxide and a ratio r of a diffraction peak intensity from a (200) plane to a diffraction peak intensity from a (100) plane of the perovskite-type oxide, which is measured using an X-ray diffraction method, satisfy Formula (2), Formula (1) A1+?[(ZryTi1-y)1-xNbx]O2, Formula (2) 0.35?r/q<0.Type: GrantFiled: September 4, 2019Date of Patent: October 17, 2023Assignee: FUJIFILM CorporationInventors: Naoki Murakami, Daigo Sawaki

Publication number: 20220268782Abstract: Ageing myocardium undergoes structural and functional changes characterized by progressive cardiomyocyte hypertrophy, interstitial fibrosis and inflammation ultimately leading to diastolic and systolic dysfunction. Whilst most focus has been placed on established risk factors such as dyslipidaemia, hypertension and obesity in accelerating cardiac ageing, a potential role for amino acids has received little attention. Here the inventors show that increased phenylalanine (PA) levels induced in vitro cytosolic oxidative stress and senescence whilst in vivo led to senile-like cardiac deterioration in young mice. Moreover, they demonstrated that hepatic PA catabolism declined with age in a p21-dependent manner, whilst p21 deficiency prevented age-related cardiac dysfunction. Finally, the inventors found that Pah cofactor BH4 reversed the age-related rise in plasma PA levels and senile cardiac alterations.Type: ApplicationFiled: July 13, 2020Publication date: August 25, 2022Inventors: Daigo Sawaki, Gabor Czibik, Geneviève Derumeaux

Publication number: 20220088015Abstract: The present invention relates to methods and pharmaceutical compositions for the treatment of age-related cardiometabolic diseases. The inventors identified osteopontin (OPN) as a critical mediator of adipose tissue remodeling and senescence in obesity and extends this observation to related co-morbidities such as cardiomyopathy. Said result raises the possibility that inhibition of OPN activity may be of value in the prevention of cardiometabolic disease, in particular metabolic cardiomyopathy for which no specific treatment is yet available. In particular, the present invention relates to a method of treating an age-related cardiometabolic disease in an elderly subject in need thereof comprising administering to the subject a therapeutically effective amount of an osteopontin (OPN) inhibitor.Type: ApplicationFiled: September 1, 2021Publication date: March 24, 2022Inventors: Geneviève DERUMEAUX, Daigo SAWAKI, Gabor CZIBIK, Takehiko YOSHIMITSU
