Advances in the Detection of Pancreatic Cancer Through Liquid Biopsy.

Pancreatic cancer refers to the development of malignant tumors in the pancreas: it is associated with high mortality rates and mostly goes undetected in its early stages for lack of symptoms. Currently, surgical treatment is the only effective way to improve the survival of pancreatic cancer patients. Therefore, it is crucial to diagnose the disease as early as possible in order to improve the survival rate of patients with pancreatic cancer.

Pubescenosides Q-R, two new phenolic glycosides from .

Two new phenolic glycosides (), along with six existing compounds (), were isolated from the ethanolic extract of roots, a traditional folk medicine. These structures were determined using HR-ESI-MS, IR, UV, and NMR (including 1 D, 2 D-NMR). The anti-inflammatory activities of three phenolic glycosides () were evaluated in the human HepG2 cell lines.

Intrapartum Results on Differing Degrees of Ketonuria in Nulliparous Women with Gestational Diabetes Mellitus during Spontaneous Labor.

To compare intrapartum results associated with differing degrees of ketonuria in nulliparous women with gestational diabetes mellitus (GDM), we implemented a retrospective cohort study comparing clinical characteristics among differing degrees of ketonuria and the duration and distribution of ketonuria at different stages of labor. We also analyzed adverse maternal and neonatal outcomes for each group. A total of 570 GDM deliveries were included; of these, 238 had negative ketonuria (41.

Early-life exposure to air pollutants and adverse pregnancy outcomes: protocol for a prospective cohort study in Beijing.

Introduction: The association between early exposure to ambient air pollution and adverse pregnancy outcomes in China is unclear. This study will assess the risk of early-life exposure to air pollutants in Beijing and explore the viability of 8-hydroxydeoxyguanosine (8-OHdG) as a biological indicator to assess oxidative stress induced by early-life exposure to air pollution.

Methods And Analysis: Here 2500 women with singleton pregnancies and their infants will be recruited from the Beijing Obstetrics and Gynecology Hospital.

A Role of sFlt-1 in Oxidative Stress and Apoptosis in Human and Mouse Pre-Eclamptic Trophoblasts.

Pre-eclampsia (PE) is a hypertensive disorder that occurs during pregnancy, and is a multifactorial disease. The antiangiogenic factor, soluble fms-like tyrosine kinase 1 (sFlt-1), has been reported to be important in the pathogenesis of PE, but the mechanism of its involvement remains unknown. To test the effects of sFlt-1 on pregnancy, we injected pregnant mice with exogenous mouse sFlt-1.

Characterization of the subsets of human NKT-like cells and the expression of Th1/Th2 cytokines in patients with unexplained recurrent spontaneous abortion.

The objective was to investigate the subsets of natural killer T (NKT)-like cells and the expression of Th1/Th2 cytokines in the peripheral blood (PB) and/or decidual tissue of patients with unexplained recurrent spontaneous abortion (URSA). The percentages of NKT-like cells in the PB and deciduas of URSA patients in early pregnancy and in the PB of nonpregnant women were analyzed by flow cytometry. The expression of interferon (IFN)-γ (Th1 cytokine) and Th2 cytokines, interleukin (IL)-4 and IL-10, in the PB and decidual tissue was measured by quantitative RT-PCR and enzyme-linked immunosorbent assay (ELISA).

Quick recovery and characterization of cell-free DNA in seminal plasma of normozoospermia and azoospermia: implications for non-invasive genetic utilities.

We established a quick and reliable method for recovering cell-free seminal DNA (cfsDNA), by using the binding-washing-elution procedure on the DNA purification column. Low variations (below 15%) among the triplicate values of cfsDNA quantity verified the reproducibility of our cfsDNA recovery method. Similar cfsDNA yield and size distribution between seminal plasma acquired by filtration and centrifugation confirmed the presence of cfsDNA.
