Association between depression and endometriosis using data from NHANES 2005-2006.

Studies on the association between depression and self-reported endometriosis are limited, and further studies are required to investigate this association. Data were collected from the National Health and Nutrition Examination Survey database (2005-2006). Based on the inclusion and exclusion criteria, 100 participants with self-reported endometriosis and 1295 participants without self-reported endometriosis were included, representing a total population of 64,989,430.

The association between dietary inflammatory index with endometriosis: NHANES 2001-2006.

Endometriosis is a common chronic inflammatory and estrogen-dependent disease that mostly affects people of childbearing age. The dietary inflammatory index (DII) is a novel instrument for assessing the overall inflammatory potential of diet. However, no studies have shown the relationship between DII and endometriosis to date.

Potential role of serum hypoxia-inducible factor 1alpha as a biomarker of delayed cerebral ischemia and poor clinical outcome after human aneurysmal subarachnoid hemorrhage: A prospective, longitudinal, multicenter, and observational study.

Objective: Hypoxia-inducible factor 1alpha (HIF-1α) functions as a crucial transcriptional mediator in hypoxic and ischemic brain response. We endeavored to assess the prognostic significance of serum HIF-1α in human aneurysmal subarachnoid hemorrhage (aSAH).

Methods: In this prospective, longitudinal, multicenter, and observational study of 257 patients with aSAH and 100 healthy controls, serum HIF-1α levels were quantified.

A comparison between ultrasound-guided AIIS injection and radiography in the diagnosis of subspine impingement in patients with FAI.

Background: Subspine impingement (SSI) does not have effective diagnostic criteria, especially in patients who also have femoroacetabular impingement (FAI). The classification of anterior inferior iliac spine (AIIS) morphology via three-dimensional CT is controversial.

Purpose: To propose a method for ultrasound-guided AIIS injection as a way to diagnose SSI and evaluate the accuracy of radiography methods, including 3-D CT and MRI, as well as intraoperative findings.

Downregulation of RTN1-C attenuates MPP-induced neuronal injury through inhibition of mGluR5 pathway in SN4741 cells.

Reticulons (RTNs) are a group of membrane-bound proteins that are dominantly localized to the endoplasmic reticulum (ER). RTN1-C, one isoform of RTNs highly expressed in the brain, has been shown to mediate neuronal injury in cerebral ischemia models. The aim of this study was to investigate the role of RTN1-C in an in vitro model of Parkinson's disease (PD) mimicked by 1-methyl-4-phenylpyridinium (MPP) treatment in SN4741 cells.

Plasma levels of alarmin HNPs 1-3 associate with lung dysfunction after cardiac surgery in children.

Background: Early onset of lung injury is considerable common after cardiac surgery and is associated with increasing in morbidity and mortality, but current clinical predictors for the occurrence of this complication always have limited positive warning value. This study aimed to evaluate whether elevated plasma levels of human neutrophil peptides (HNPs) 1-3 herald impaired lung function in infants and young children after cardiac surgery necessitating cardiopulmonary bypass (CPB).

Methods: Consecutive children younger than 3 years old who underwent cardiac surgery were prospectively enrolled.

Clinical observations of sequential therapy with Chinese medicine and hysteroscopic mechanical stimulation of the endometrium in infertile patients with repeated implantation failure undergoing frozen-thawed embryo transfer.

Objectives: To investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.

Methods: In the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.

Polydopamine-coated magnetic nanoparticles for enrichment and direct detection of small molecule pollutants coupled with MALDI-TOF-MS.

Polydopamine-coated Fe(3)O(4) nanoparticles (Fe(3)O(4)@PDA NPs) were synthesized and applied as matrix for the detection of pollutants by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The synthesis of Fe(3)O(4)@PDA NPs was accomplished in 30 min by in situ polymerization of dopamine without any toxic reagent. Using Fe(3)O(4)@PDA NPs as matrix of MALDI-TOF, eleven small molecule pollutants (molecular weight from 251.

Colorimetric detection of copper ions in tap water during the synthesis of silver/dopamine nanoparticles.

A facile, economic and eco-friendly colorimetric sensor for Cu(2+) using dopamine/silver nanoparticles was developed. The sensor shows excellent sensitivity and selectivity toward Cu(2+) in the range of 3.2-512 ppb and can be applied for Cu(2+) detection in tap water.

Investigation on quantitative structure activity relationships and pharmacophore modeling of a series of mGluR2 antagonists.

MGluR2 is G protein-coupled receptor that is targeted for diseases like anxiety, depression, Parkinson's disease and schizophrenia. Herein, we report the three-dimensional quantitative structure-activity relationship (3D-QSAR) studies of a series of 1,3-dihydrobenzo[ b][1,4]diazepin-2-one derivatives as mGluR2 antagonists. Two series of models using two different activities of the antagonists against rat mGluR2, which has been shown to be very similar to the human mGluR2, (activity I: inhibition of [(3)H]-LY354740; activity II: mGluR2 (1S,3R)-ACPD inhibition of forskolin stimulated cAMP.

A core-shell magnetic mesoporous silica sorbent for organic targets with high extraction performance and anti-interference ability.

C(18)-functionalized mesoporous silica shell was successfully fabricated on the surface of an Fe(3)O(4)/SiO(2) core to obtain an Fe(3)O(4)/SiO(2)/SiO(2)-C(18) magnetic microsphere. The microsphere exhibited high extraction efficiency to organic targets and strong anti-interference ability to natural organic matter. It could be easily isolated from water solution after extraction.

Preparation of a chitosan-coated C(18)-functionalized magnetite nanoparticle sorbent for extraction of phthalate ester compounds from environmental water samples.

Novel superparamagnetic chitosan-coated C(18)-functionalized magnetite nanoparticles (MNPs) were successfully synthesized and applied as an effective sorbent for the preconcentration of several typical phthalate ester compounds from environmental water samples. The MNPs were 20 nm in diameter and had a high magnetic saturation value (52 emu g(-1)), which endowed the sorbent with a large surface area and the convenience of isolation from water samples. Phthalate esters could be extracted by the interior octadecyl groups through hydrophobic interaction.

Expression of Rho GDIalpha in rat osteoblasts intermittently exposed to parathyroid hormone in vitro and in vivo.

Aim: To investigate the mechanism of the bone-forming effects of intermittent parathyroid hormone (PTH) administration and to search for novel molecules of bone anabolism via the PTH signaling pathway.

Methods: Primary cultures of rat osteoblasts (ROBs) were divided into an intermittent PTH-treated group (Itm) and a control group (Ctr). Imitating the pharmacokinetics of intermittent PTH administration in vivo, the ROBs in the Itm group were exposed to PTH for 6 h in a 24-h incubation cycle, and the ROBs in the Ctr group were exposed to vehicle for the entire incubation cycle.
