To observe the effects of resveratrol (Res) on antioxidative function and estrogen level in an Alzheimer's disease (AD) mouse model.First, we examined Res AD mice model. SAMP8 were selected as model, normal-aging SAMR1 used control group. The model randomly divided into three groups: a group, high-dose group (40mg/kg, intraperitoneal (ip)), low-dose (20mg/kg, ip). After receiving medication for 15 days, subjected to water maze test assess their spatial discrimination. spectrophotometric...

Skeletal muscle atrophy in chronic kidney disease (CKD) leads to a decline quality of life and increased risk morbidity mortality. We have obtained evidence that oxidative stress is essential the progression CKD-related atrophy. Whether Saikosaponin A D, two emerging antioxidants extracted from Bupleurum chinense DC, alleviate remains be further studied. The purpose this study was investigate effects mechanisms these components on CKD complicated with atrophy.In research, dystrophy model...

Abstract: Surface modification of nanocarriers with amphiphilic polymer polyethylene glycol (PEG), known as PEGylation, is regarded a major breakthrough in the application nanocarriers. However, PEGylated (including liposomes and polymeric nanoparticles) induce what referred to “accelerated blood clearance (ABC) phenomenon” upon repeated injection consequently they lose their sustained circulation characteristics. Despite this, present authors are not aware any reports accelerated due for...

Abstract Background The gut microbiome regulates host energy balance and adiposity-related metabolic consequences, but it remains unknown how the modulates body weight response to physical activity (PA). Methods Nested in Health Professionals Follow-up Study, a subcohort of 307 healthy men (mean[SD] age, 70[4] years) provided stool blood samples 2012–2013. Data from cohort long-term follow-ups accelerometer, doubly labeled water, plasma biomarker measurements during time collection were used...

G protein-coupled estrogen receptor (GPER) is recently identified as a membrane-associated that mediates non-genomic effects of estrogen. Our previous immunohistochemistry study found an association between GPER and the proliferation epithelial ovarian cancer. However, contributions mechanisms in cancers are not clear. We have examined role α (ERα)-negative/GPER positive OVCAR5 cancer cell line. MTT assay was used to detect proliferation. BrdU incorporation measure cells S-phase. Protein...

Abstract Colorectal cancer (CRC) is the third most common and lethal type worldwide. Although CRC incidence in older population has decreased many countries, early-onset cases (< 50 years age, EOCRC) have been rapidly increasing globally. The fecal microbiome reproducibly associated with CRC. However, differences according to age of onset, stage, anatomic location, genomic instability remain only minimally explored. Here, we integrated data generated from ONCOBIOME consortium, Cancer...

Microbial fermentation has been widely applied in traditional Chinese medicine (TCM) for thousands of years China. Various beneficial effects applications TCM or herbals have reported, such as enhanced anti-ovarian cancer, antioxidative activity, and neuroprotective effects. Ge-Gen-Qin-Lian decoction (GQD), a classic formula, used to treat type 2 diabetes mellitus In this study, GQD was fermented with Saccharomyces cerevisiae, the antidiabetic activities overall chemical profiles raw (FGQD)...

In this study, we investigated the impact of endogenous hydrogen sulfide (H2S) on toll-like receptors (TLRs)-mediated inflammatory response and apoptosis in renal ischemia-reperfusion injury (IRI). Twenty-four male Wistar rats were randomly divided into four groups: sham, IR, IR + propargylglycine (PAG) hydroxylamine (HA). After right nephrectomy, given saline for sham group, PAG group HA through left artery 20 min. Five minutes after drug administration, all except underwent 45 min ischemia...
