Evaluation of the diagnostic performance of colposcopy in the detection of cervical high-grade squamous intraepithelial lesions among women with transformation zone type 3.

Background: Inaccurate colposcopy diagnosis may lead to inappropriate management and increase the incidence of cervical cancer. This study aimed to evaluate the diagnostic accuracy of colposcopy in the detection of histologic cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in women with transformation zone type 3 (TZ3).

Methods: Records from 764 patients with TZ3 who underwent colposcopy-directed biopsy and/or endocervical curettage in Putuo Hospital China between February 2020 and March 2023 were retrospectively collected.

An electrochemical biosensor based on DNA tetrahedron nanoprobe for sensitive and selective detection of doxorubicin.

Doxorubicin (DOX) is a clinical chemotherapeutic drug and patients usually suffer from dose-dependent cytotoxic and side effects during chemotherapy process with DOX. Therefore, developing a reliable strategy for DOX analysis in biological samples for dosage guidance during chemotherapy process is of great significance. Herein, a sensitive and selective electrochemical biosensor for DOX detection was designed based on gold nanoparticles (AuNPs) and DNA tetrahedron (TDN) nanoprobe bifunctional glassy carbon electrode that could detect DOX in human serum and cell lysate samples.

Detection of cervical high-grade squamous intraepithelial lesions and assessing diagnostic performance of colposcopy among women with oncogenic HPV.

Background: HPV screening tests may improve cervical cancer risk stratification and better guide decisions about follow-up with colposcopy/biopsy. This study aimed to estimate the risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) among women with oncogenic HPV types and evaluate the performance of colposcopy in the diagnosis of histologic CIN2 + at Putuo Hospital, Shanghai, China.

Methods: This cross-sectional survey was conducted from February 2020 to December 2022 among women who were referred to colposcopy.

Glutamate-aspartate transporter 1 attenuates oxygen-glucose deprivation-induced injury by promoting glutamate metabolism in primary cortical neurons.

Ischemic stroke is a common cerebral disease. However, the treatment for the disease is limited. Daurian ground squirrel (GS; Spermophilus dauricus), a hibernating mammalian species, is highly tolerant to ischemia.

Hydrogen Sulfide Contributes to Uterine Quiescence Through Inhibition of NLRP3 Inflammasome Activation by Suppressing the TLR4/NF-κB Signalling Pathway.

Background: The NLRP3 inflammasome plays a critical role in inflammatory responses in various diseases. Our previous study showed that NLRP3 expression was significantly increased in human pregnancy tissue during term labour. Therefore, we explored whether NLRP3 participated in inflammatory responses of preterm and term labour and whether this process could be relieved by HS, one anti-inflammatory gasotransmitter.

Is cognitive behavioral therapy a better choice for women with postnatal depression? A systematic review and meta-analysis.

The present study evaluated the combined effectiveness of cognitive behavioral therapy (CBT) for postnatal depression. A systematic search was conducted across databases including PubMed, Embase, and the Cochrane library to identify the randomized controlled trials (RCTs) that assessing CBT versus control for postnatal depression until March 2017. Data was extracted by two reviewers, independently.

The Inhibitory Effect of α/β-Hydrolase Domain-Containing 6 (ABHD6) on the Surface Targeting of GluA2- and GluA3-Containing AMPA Receptors.

The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptors (AMPARs) are major excitatory receptors that mediate fast neurotransmission in the mammalian brain. The surface expression of functional AMPARs is crucial for synaptic transmission and plasticity. AMPAR auxiliary subunits control the biosynthesis, membrane trafficking, and synaptic targeting of AMPARs.

[Determination of 14 aniline derivatives in water by liquid chromatography-tandem mass spectrometry].

A new and fast method was developed for the simultaneous determination of 14 aniline derivatives ( ADs) in water by direct injection-liquid chromatography-tandem mass spectrometry (LC-MS/MS) through optimizing chromatographic and mass spectrometric conditions. The water sample was filtered through a 0.45 µm polyether sulfone (PES) microfiltration membrane.

Application of GC-triple quadrupole MS in the quantitative confirmation of polycyclic aromatic hydrocarbons and phthalic acid esters in soil.

A new multi-residue method has been developed and validated for the simultaneous analysis of 34 polycyclic aromatic hydrocarbons (PAHs) and phthalic acid esters (PAEs) in soil at trace levels by gas chromatography coupled to triple quadrupole mass spectrometry. Microwave extraction and solid-phase extraction have been employed prior to gas chromatography tandem mass spectrometry analysis. Quality parameters have been established using matrix spike and reference material IRM 104A.

Sensitive determination of aliphatic amines by high-performance liquid chromatography with a new fluorogenic probe 3-(4-fluorinebenzoyl)-2-quinoline carboxaldehyde.

A new fluorogenic reagent 3-(4-fluorinebenzoyl)-2-quinoline carboxaldehyde (FBQCA) has been synthesized and used as a derivatizing reagent for the determination of aliphatic amines with HPLC. The reagent is nonfluorescent, but forms highly fluorescent isoindole upon the reaction with primary amines in alkaline medium. Eleven amine derivatives were baseline separated in 8 min using a gradient elution on a C(8) column and detected with fluorescence detection at lambda(ex)/lambda(em) = 480/546 nm.
