The overall goal of this proposal is to investigate effects of obesity on pharmacokinetics of immunoglobulin G (IgG) and to develop strategies for optimization of dosing of IgG in obese patients. There is an ongoing debate regarding the most appropriate dosing of IgG formulations in obese patients. Obesity poses significant health risks; and evidence supporting dosing strategies of IgG in obese patients is inadequate. Some of the adverse reactions have been attributed to a relative overdosing in these patients, due to a limited distribution of IgG into fat tissue.
The purpose of this study is to estimate the effects of diet and exercise interventions on body weight, cardiovascular metabolic markers, executive function, and intestinal flora among undergraduate students, as well as the underlying mechanisms.
Neoadjuvant treatment is an important treatment for early breast cancer patients. Patients with triple negative subtype who achieved pCR after neoadjuvant treatment would have longer survival. The neoadjuvant treatment for her2 negative patient was chemotherapy with combined drugs. However, not all patients benefit from chemotherapy but suffer from chemotherapy-related side effects. It was unknown for a patient who could benefit from which drug before chemotherapy. Drug sensitivity screening in vitro was a promising method for choosing chemotherapy. But there was no method could select effective drugs accurately for breast cancer patients until now. Previously, investigators developed a patient-derived tumor-like cell clusters in vitro culture technology. Feasibility for guiding clinical treatment by drug sensitivity screening based on this technology have been explored by preliminary exploration with a well corresponding. And the results have been published. This study will explore whether drug screening in vitro patient-derived tumor-like cell clusters from breast cancer tissue could be a method for selection of chemotherapy for her2 negative participants.

The primary objective is to determine the safety and tolerability of SH3809 in subjects with advanced solid tumors. The second objective is to evaluate the PK profile and preliminary efficacy of SH3809 in solid tumors.
The majority of cardiovascular diseases (CVD) occur in men and women ≥60 years of age. Vascular dysfunction, including endothelial dysfunction, as assessed by reduced endothelium-dependent dilation (EDD), and stiffening of the large elastic arteries (i.e., aortic and carotid artery stiffening), is a major mechanism of increased risk of CVD in older adults. Excess production of ROS (reactive oxygen species) by mitochondria (mtROS) has emerged as a central feature of vascular oxidative stress with aging and driver of age-related vascular dysfunction. As such, identifying novel strategies to decrease mtROS and improve vascular function, to ultimately reduce the risk of age-related CVD, is an important biomedical objective. MitoQ is a mitochondria-targeted antioxidant that accumulates at the inner mitochondrial membrane where it is optimally positioned to reduce mtROS. Preclinical findings showed that 4 weeks of oral MitoQ supplementation completely restored EDD in old mice, ameliorated mtROS-associated suppression of EDD, and was associated with reduced arterial mtROS, oxidative stress, and improved mitochondrial health. MitoQ therapy also reduced aortic stiffness in old mice. A recent small pilot study of older adults (n=20) found that supplementation with MitoQ was well-tolerated, improved endothelial function, and reduced plasma levels of oxidized low-density lipoprotein, a circulating biomarker of oxidative stress. Consistent with the preclinical findings, preliminary mechanistic assessments in subsets of subjects from the pilot study suggested that improved endothelial function with MitoQ was mediated by reduced endothelial cell mtROS production, associated reductions in tonic mtROS-related suppression of EDD, and improved mitochondrial health, linked in part to changes in circulating factors in the serum induced by chronic MitoQ supplementation. Lastly, MitoQ reduced aortic stiffness in older adults who exhibited age-related aortic stiffening at baseline. The investigators are conducting a randomized, placebo-controlled, double-blind clinical trial to establish oral MitoQ (20 mg/day; MitoQ, Ltd.) for 3 months vs. placebo (n=56/group) for improving endothelial function in older men and women (≥60 years), and determine the mechanisms by which MitoQ improves endothelial function. The investigators will also assess the effect of MitoQ on aortic stiffness.
