Assessing the measurement invariance of Free Will and Determinism Plus scale across four languages: a registered report.

Free will is assumed to be the core of an individual's self-concept. Belief in free will has been studied extensively and was found to be correlated with many behavioural and psychological outcomes. Although developed and validated in the West, the Free will and Determinism Plus (FAD-Plus) scale has been translated, used, and interpreted as a measurement of free will beliefs in multiple cultures.

[Preimplantation genetic testing for a Chinese pedigree affected with Rett syndrome].

Objective: To carry out preimplantation genetic testing (PGT) for a Chinese pedigree affected with Rett syndrome (RTT).

Methods: A pedigree affected with RTT who had presented at the First Hospital of Jilin University on June 4, 2021 was selected as the study subject. Variant of the MECP2 gene was analyzed by next generation sequencing (NGS) and Sanger sequencing.

Rapid chiral purity identification of mandelic acid by Raman spectra in the O-H stretching region.

Chiral molecules play a very important role in biological systems, and more and more chiral drugs are used in the treatment of diseases. Mandelic acid (MA) is an important chiral starting substance or the key intermediate of some chiral drugs, and the rapid detection of its chiral purity is very important in the synthesis, separation and detection of drugs. In this study, we developed a method for rapid determination of chiral purity of MA by Raman spectroscopy, and measured a series of Raman spectra of different chiral MA.

Risk prediction of gestational diabetes mellitus in women with polycystic ovary syndrome based on a nomogram model.

Women with polycystic ovary syndrome are prone to develop gestational diabetes mellitus, a disease which may have significant impact on the postpartum health of both mother and infant. We performed a retrospective cohort study to develop and test a model that could predict gestational diabetes mellitus in the first trimester in women with polycystic ovary syndrome. Our study included 434 pregnant women who were referred to the obstetrics department between December 2017 and March 2020 with a diagnosis of polycystic ovary syndrome.

Development and validation of a rapid kit for authenticity of murine meat in meat products with a species-specific PCR assay.

Adulteration of meat products with murine meat poses a huge threat to consumer health and leads to serious disruption in food markets. Species authentication of murine meat is still technically challenging. We, therefore, developed a species-specific PCR kit consisting of murine meat DNA extraction, PCR reaction and identifying systems.

Development of a PCR-based assay for detection of Chinese mink tissue in meat products based on the mitochondrial DNA cytochrome- gene.

Species authentication of meat product origins has become an important subject for ensuring the health of consumers. Based on the cytochrome gene, we developed a PCR-based assay kit for identification of Chinese mink tissues from 10 animal species in meat products, and to evaluate its quality indices including specificity, stability, sensitivity, and repeatability. Kits were made up of DNA extraction and PCR amplification systems based on species-specific, and universal primers.

Nature of Monomeric Molybdenum(VI) Cations in Acid Solutions Using Theoretical Calculations and Raman Spectroscopy.

The composition and structures of the two protonated species formed from uncharged molybdic acid, MoO(OH)(OH), in strongly acidic solutions have been investigated using a combination of density functional theory calculations, first-principles molecular dynamics simulations, and Raman spectroscopy. The calculations show that both protonated species maintain the original octahedral structure of molybdic acid. Computed p K values indicated that the ═O moieties are the proton acceptor sites and, therefore, that MoO(OH)(OH) and Mo(OH)(OH) are the probable protonated forms of Mo(VI) in strong acid solutions, rather than the previously accepted MoO(OH)(OH) ( x = 1, 2) species.

[Development on DNA detection kit of fox and its application in common meat products].

Objective: To develop a kind of DNA extraction and detection kit for identification of fox source composition.

Methods: Using the modern DNA fingerprint technology, the DNA extraction method was improved, and DNA extraction and detection reagent was developed to obtain the fox polymerase chain reaction( PCR)detection kit. The performance parameters of the kit were evaluated.

Placenta accreta spectrum disorder trends in the context of the universal two-child policy in China and the risk of hysterectomy.

Objective: To identify both the trends in placenta accreta spectrum (PAS) disorders in the context of the universal two-child policy in China and risk factors for hysterectomy.

Methods: The present retrospective analysis included confirmed PAS disorders during cesarean delivery at a tertiary hospital in Changsha, Hunan, China, from January 1, 2007, to December 31, 2016. Multivariable logistic regression was used to estimate the risk of hysterectomy.
