Background: The aim of this study was to explore the principal frequency components of the heart rate and blood pressure variability in the low frequency (LF) and very low frequency (VLF) band. The spectral composition of...
Independence of circadian entrainment state and responses to melatonin in male Siberian hamsters [0.03%]

Background: Earlier studies from this laboratory reported that light and its spectra influence reproduction in the Indian skipper frog Rana cyanophlyctis through both ocular and extra ocular photoreception. During the cou...
Monitoring immediate-early gene expression through firefly luciferase imaging of HRS/J hairless mice [0.03%]
通过HRS/J无毛小鼠的萤火虫荧光素酶成像监测立即早期基因表达

Background: Rhythmicity in core body temperature has been extensively studied in humans and laboratory animals but much less in farm animals. Extending the study of rhythmicity of body temperature to farm animals is impor...
Chronic treatment with carvedilol improves ventricular function and reduces myocyte apoptosis in an animal model of heart failure [0.03%]

Chukwuka C Okafor et al.
Background: Beta blocker treatment has emerged as an effective treatment modality for heart failure. Interestingly, beta-blockers can activate both pro-apoptotic and anti-apoptotic pathways. Nevertheless, the mechanism fo...
Role of glucocorticoids in mediating effects of fasting and diabetes on hypothalamic gene expression [0.03%]
糖皮质激素在介导饥饿和糖尿病对下丘脑基因表达的影响中的作用
Hideo Makimura,Tooru M Mizuno,Fumiko Isoda et al.
Hideo Makimura et al.
Background: Fasting and diabetes are characterized by elevated glucocorticoids and reduced insulin, leptin, elevated hypothalamic AGRP and NPY mRNA, and reduced hypothalamic POMC mRNA. Although leptin replacement can reve...
Adrenalectomy stimulates hypothalamic proopiomelanocortin expression but does not correct diet-induced obesity [0.03%]
肾上腺切除术可刺激下丘脑促黑素细胞皮质醇的表达但不能纠正饮食诱导的肥胖症
Hideo Makimura,Tooru M Mizuno,Joe Beasley et al.
Hideo Makimura et al.
Background: Elevated glucocorticoid production and reduced hypothalamic POMC mRNA can cause obese phenotypes. Conversely, adrenalectomy can reverse obese phenotypes caused by the absence of leptin, a model in which glucoc...

Heat induced HSP20 phosphorylation without increased cyclic nucleotide levels in swine carotid media [0.03%]
热诱导猪颈动脉中层HSP20磷酸化而不增加环核苷酸水平
Christopher M Rembold,Elizabeth Kaufman
Christopher M Rembold
Background: Heat pretreatment of swine carotid artery has been shown to increase ser16-heat shock protein 20 (HSP20) phosphorylation and suppress force, i.e., reduce force with only minimal reduction in ser19-myosin regul...
