IL-8 production and AP-1 transactivation induced by UVA in human keratinocytes: roles of D-alpha-tocopherol 总被引:1,自引:0,他引:1
Identification of individual response-signal pathway induced by UVA-irradiation is necessary for understanding photo-biological and -pathological mechanisms with respect to the prevention of UV-irradiated skin damage and aging. Here, we investigated the role of D-alpha-tocopherol in the regulation of IL-8 production and AP-1 binding activity in UVA-irradiated human keratinocytes. UVA dramatically upregulated IL-8 mRNA expression and protein secretion and enhanced the AP-1-DNA binding activity. These effects of UVA irradiation were effectively reduced by D-alpha-tocopherol in a dose-dependent manner. The human keratinocytes expressed various NAD(P)H oxidase components, gp91phox homologues Nox1, and p22phox, p47phox, p67phox, as well as NOXO1, suggesting that cellular stress induced by UVA included the activation of non-phagocytic NADPH oxidase system, leading to AP-1 transactivation and IL-8 expression. D-alpha-tocopherol significantly inhibited the NADPH oxidase activity and the formation of malondialdehyde-thiobarbituric acid under UVA exposure. These results demonstrated that D-alpha-tocopherol may be able to prevent the IL-8 upregulation and the increase in AP-1 activation induced by UVA irradiation through down-modulating cellular oxidative stress. 相似文献

A cardiac cavernous hemangioma is a rare, primary, benign tumor that is usually diagnosed in young or middle-aged patients. In this article, we report the case of a 71-year-old male patient whose doctors incidentally discovered a heart tumor on his transthoracic echocardiography. Triple-phase computed tomography (CT) (pre-contrast, arterial and portal venous) missed the lesion, and magnetic resonance imaging (MRI) revealed a small, oval tumor attached to the wall of the right ventricle. The tumor was successfully removed surgically, and the patient recovered after 2 weeks. A histopathological examination resulted in the diagnosis of a benign cavernous hemangioma. 相似文献

A ruptured blister-like aneurysm of the internal carotid artery is a rare event with a high risk of recurrence and mortality. Selecting an appropriate treatment modality remains challenging due to a lack of consensus or specific recommendations in the literature. In this article, we present the case of a 68-year-old man who presented with ruptured blister-like aneurysms in the supraclinoid portion of the internal carotid artery. The patient was diagnosed and successfully managed using an endovascular coil embolization technique at our hospital. We aim to illustrate and share our experiences with this rare occurrence, which may assist in the treatment of similar cases in the future. 相似文献

Though anthropometric measurement (AM) frequently occurs in school settings, it is not without risks to child wellbeing. The aim of this scoping review was to examine how AM in school settings takes place and is reported on to make recommendations on best practices. We identified and extracted data from 440 studies published since 2005 that conducted AM in school (pre-school through secondary/high school) settings. Privacy and sensitivity of AM were unclear in over 90% of studies. Thirty-one studies (7.0%) reported protecting student privacy, while nine (2.0%) reported public measurement. Only five studies reported sensitivity regarding AM (1.1%). Exactly who conducted AM was not specified in 201 studies (45.7%). Sixty-nine studies did not provide a weight status criteria citation (19.2%), and 10 used an incorrect citation (2.7%). In summary, serious shortcomings in the reporting of how AM is conducted and by whom, along with details concerning weight status classification, are evident. There is considerable room for improvement regarding the reporting of key methodological details. We propose best practices for AM in school settings, which also double as conditions that should be met before AM takes place in school settings. 相似文献
