Energy metabolism in cancer stem cells.

Normal cells mainly rely on oxidative phosphorylation as an effective energy source in the presence of oxygen. In contrast, most cancer cells use less efficient glycolysis to produce ATP and essential biomolecules. Cancer cells gain the characteristics of metabolic adaptation by reprogramming their metabolic mechanisms to meet the needs of rapid tumor growth.

Milk phospholipid supplementation mediates colonization resistance of mice against Salmonella infection in association with modification of gut microbiota.

Gut microbiota-mediated colonization resistance against enteropathogens is known to be greatly influenced by bioactive food compounds. This work aims to investigate the effects of milk phospholipid (MP) supplementation on the colonization resistance of mice to Salmonella enterica serovar Typhimurium (S. Typhimurium) infection, with the focus mainly on the change of gut microbiota.

Perspectives regarding family disclosure of genetic research results in three racial and ethnic minority populations.

The lack of data on perspectives of racial and ethnic minority populations regarding family disclosure of individual research results (IRR) hinders the development of return of IRR policies and practices that are meaningful and culturally appropriate in diverse populations. This research aims to uncover preferences regarding family disclosure of IRR and identify factors that may shape the preferences in three minority populations. Nine focus groups with 68 adult African American, Hispanic/Latinx, and American Indian/Alaska Native individuals were conducted.

Extendable, large-field multi-modal optical imaging system for measuring tissue hemodynamics.

Simultaneous imaging of multiple hemodynamic parameters helps to evaluate the physiological and pathological status of biological tissue. To achieve multimodal hemodynamics imaging with a large field of view, an infinite conjugate relay lens system compatible with the standard C-Mount camera lens is designed to adapt one camera lens with multiple CCD/CMOS cameras for simultaneously multi-wavelength imaging. Using this relay lens system, dual wavelength reflectance imaging and laser speckle contrast imaging were combined to simultaneously detect the changes in blood flow, oxygenation, and hemoglobin concentrations.

Ursolic acid reverses liver fibrosis by inhibiting interactive NOX4/ROS and RhoA/ROCK1 signalling pathways.

Liver fibrosis is the reversible deposition of extracellular matrix (ECM) and scar formation after liver damage by various stimuli. The interaction between NOX4/ROS and RhoA/ROCK1 in liver fibrosis is not yet clear. Ursolic acid (UA) is a traditional Chinese medicine with anti-fibrotic effects, but the molecular mechanism underlying these effects is still unclear.

Dityrosine suppresses the cytoprotective action of thyroid hormone T3 inhibiting thyroid hormone receptor-mediated transcriptional activation.

Dityrosine (Dityr) is the most common oxidized form of tyrosine. In the previous studies of mice treated with dityrosine, cell death in the pancreas, kidneys, and liver was detected in the presence of enhanced plasma triiodothyronine (T3) content. Due to its structural similarity with the thyroid hormone T3, we hypothesized that dityrosine might disrupt T3-dependent endocrine signaling.

Design of light/ROS cascade-responsive tumor-recognizing nanotheranostics for spatiotemporally controlled drug release in locoregional photo-chemotherapy.

Carrier-free nanotheranostics with high drug loading and no carrier-related toxicity are highly promising cancer therapy agents. However, the limited tumor accumulation and poorly controlled drug release of these nanotheranostics continue to be major challenges that restrict clinical applications. In this study, we develop a tumor-recognizing carrier-free nanotheranostic with light/reactive oxygen species (ROS) cascade-responsiveness for spatiotemporally selective photo-chemotherapy.

Serum omentin-1 level in patients with benign prostatic hyperplasia.

Backgroud: To evaluate the relationship between omentin-1 and benign prostatic hyperplasia (BPH). BPH is the most common urological disease in elderly men worldwide. Lower serum omentin-1 levels were reported to be negatively associated with the incidence of inflammation, diabetes, obesity and metabolic syndrome, which all play a role in the development of BPH.

Ursolic acid improves the bacterial community mapping of the intestinal tract in liver fibrosis mice.

Liver fibrosis often appears in chronic liver disease, with extracellular matrix (ECM) deposition as the main feature. Due to the presence of the liver-gut axis, the destruction of intestinal homeostasis is often accompanied by the development of liver fibrosis. The inconsistent ecological environment of different intestinal sites may lead to differences in the microbiota.

Enhanced piezoelectric and acoustic performances of poly(vinylidene fluoride-trifluoroethylene) films for hydroacoustic applications.

Concerning the study of flexible piezoelectric devices, both scholars and engineers propose that poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) shows more merits than oriented polyvinylidene fluoride (OPVDF) in terms of dielectric, piezoelectric, mechanic-electric, acoustic emission reception performances, etc. Thus, in this study, to clarify the differences between the two types of polymers on their ferroelectric and piezoelectric behaviors, we systematically investigated samples to analyze their molecular structures and phase structures, and to compare their dielectric properties and acoustic emission reception performances. It was found that the wedge effect of TrFE, P(VDF-TrFE), possesses higher regular β phase crystal grains, which are easier to order along the electric field and possess more ordered static charge distribution than that of OPVDF.

Neoadjuvant radiotherapy improves overall survival for T3/4N+M0 rectal cancer patients: a population-based study of 20300 patients.

Background: Neoadjuvant radiotherapy (RT) has been shown to improve local control; however, whether it can improve overall survival (OS) in locally advanced rectal cancer (LARC) patients remains controversial. We therefore aimed to examine the benefits of surgery alone, neoadjuvant radiotherapy (RT), adjuvant RT, and surgery plus chemotherapy in stage II (T3/4N0M0) and III (any T and N + M0) on the OS of rectal cancer patients.

Methods: Date from the Surveillance, Epidemiology, and End Results (SEER) database diagnosed between 2004 and 2016 were used.
