Nucleon Electric Polarizabilities and Nucleon-Pion Scattering at the Physical Pion Mass.

We present a lattice QCD calculation of the nucleon electric polarizabilities at the physical pion mass. Our findings reveal the substantial contributions of the Nπ states to these polarizabilities. Without considering these contributions, the lattice results fall significantly below the experimental values, consistent with previous lattice studies.

Lattice QCD Calculation of Electroweak Box Contributions to Superallowed Nuclear and Neutron Beta Decays.

We present the first lattice QCD calculation of the universal axial γW-box contribution □_{γW}^{VA} to both superallowed nuclear and neutron beta decays. This contribution emerges as a significant component within the theoretical uncertainties surrounding the extraction of |V_{ud}| from superallowed decays. Our calculation is conducted using two domain wall fermion ensembles at the physical pion mass.

Dexmedetomidine suppressed the biological behavior of RAW264.7 cells treated with LPS by down-regulating HOTAIR.

Background: Previous studies have revealed dexmedetomidine have potential protective effects on vital organs by inhibiting the release of inflammatory cytokines. To investigate the effects of dexmedetomidine on sepsis, especially in the initial inflammatory stage of sepsis. RAW264.

Portal hypertension caused by pancreatic cancer: Multidetector computed tomography diagnosis and multivariate analysis of variceal hemorrhage.

Context: Pancreatic cancer portal hypertension (PCPH) is a rare cause of gastrointestinal bleeding. This study retrospectively assessed gastrointestinal bleeding risk factors in 57 PCPH patients diagnosed via multidetector computed tomography (MDCT).

Materials And Methods: The data of patients with pancreatic cancer from January 2008 to January 2018 at Qingdao Municipal Hospital were reviewed.

High Glucose Level Induces Cardiovascular Dysplasia During Early Embryo Development.

The incidence of gestational diabetes mellitus (GDM) has increased dramatically amongst multiethnic population. However, how gestational diabetes mellitus damages the developing embryo is still unknown. In this study, we used yolk sac membrane (YSM) model to investigate angiogenesis in the developing chick embryo.

Stepwise stent deployment technique for tandem intracranial aneurysms: a review of 21 cases.

Objectives: We performed this study to report our experience using a stepwise stent deployment technique for the treatment of tandem intracranial aneurysms.

Methods: Patients with intracranial tandem aneurysms that were treated with a stepwise stent deployment technique between May 2009 and June 2013 were retrospectively reviewed.

Results: Twenty-one patients with 42 tandem aneurysms were identified (11 men, 10 women), with a mean age of 53.

Biphasic influence of dexamethasone exposure on embryonic vertebrate skeleton development.

Dexamethasone (Dex) has anti-inflammatory and immunomodulatory properties against many conditions. There is a potential teratogenic risk, however, for pregnant women receiving Dex treatment. It has been claimed that Dex exposure during pregnancy could affect osteogenesis in the developing embryo, which still remains highly controversial.

Excess ROS induced by AAPH causes myocardial hypertrophy in the developing chick embryo.

Background: The developing embryo is very sensitive to oxidative stress and excess reactive oxygen species (ROS) generation is often associated with cardiovascular malformation. However, little is known about the adverse effects of ROS during heart morphogenesis, especially during the formation of the atria and ventricles.

Methods And Results: We have treated early chick embryos with 2,2-azobis (2-amidinopropane) dihydrochloride (AAPH) to generate free radicals in the developing heart.

A pivotal role of the vascular endothelial growth factor signaling pathway in the formation of venous hypertension-induced dural arteriovenous fistulas.

Dural arteriovenous fistulas (DAVFs) are associated with venous hypertension. Numerous studies have revealed high expression levels of vascular endothelial growth factor (VEGF) in human DAVF specimens, as well as in animal models of experimental venous hypertension. The objective of the present study was to clarify whether the VEGF signaling pathway is important in the development of DAVFs.

The negative influence of high-glucose ambience on neurogenesis in developing quail embryos.

Gestational diabetes is defined as glucose intolerance during pregnancy and it is presented as high blood glucose levels during the onset pregnancy. This condition has an adverse impact on fetal development but the mechanism involved is still not fully understood. In this study, we investigated the effects of high glucose on the developing quail embryo, especially its impact on the development of the nervous system.

Exposure to 2,5-hexanedione can induce neural malformations in chick embryos.

Worldwide, n-hexane is an organic solvent widely used in numerous industries such as chemical engineering, pharmaceutical and cosmetic industry. 2,5-Hexanedione (2,5-HD) is the main metabolite of n-hexane. It is now gradually recognized that chronic exposure to n-hexane could harm the health of people.

Effects of D-cycloserine on extinction and reinstatement of morphine-induced conditioned place preference.

d-Cycloserine (DCS), a partial agonist at the strychnine-insensitive glycine recognition site on the N-methyl-d-aspartate (NMDA) receptor complex, has been shown to facilitate the extinction and prevent the relapse of cocaine-induced conditioned place preference (CPP) when administered before or after each extinction trail. However, some studies have suggested that DCS does not influence or even enhance relapse of seeking behavior on cocaine self-administration (SA) in rats or cocaine-dependent individuals undergoing clinical exposure treatment. Furthermore, there are no reports on the effects of DCS and the extinction of morphine-conditioned behaviors in mice.
