Factors affecting the accuracy and reliability of the measurement of anti-Müllerian hormone concentration in the clinic.

Objective: We aimed to identify the factors that influence serum anti-Müllerian hormone (AMH) concentration measurements.

Methods: We collected serum samples between May and September 2018 and compared the effect on AMH concentration measured by ELISA of conditions including venepuncture, storage time, storage temperature, locations of the reaction microplate, and the use of the oral contraceptive pill and gonadotrophin-releasing hormone (GnRH).

Results: AMH concentration was not affected by food intake but was affected by haemolysis.

Human mesenchymal stem cell treatment of premature ovarian failure: new challenges and opportunities.

Premature ovarian failure (POF) is one of the common disorders found in women leading to 1% female infertility. Clinical features of POF are hypoestrogenism or estrogen deficiency, increased gonadotropin level, and, most importantly, amenorrhea. With the development of regenerative medicine, human mesenchymal stem cell (hMSC) therapy brings new prospects for POF.

Assessment of Anti-Mullerian Hormone and Anti-Mullerian Hormone Type II Receptor Variants in Women with Repeated Implantation Failures.

Repeated implantation failure (RIF) is a common endocrine disease that causes female infertility and the etiology is unknown. The abnormal expression of key proteins and hormones at the maternal-fetal interface affected the maternal-fetal communication and leads to adverse pregnancy outcomes. The expression of anti-Mullerian hormone (AMH) and AMH receptor II (AMHRII) was observed in the endometrium.

[Breeding of new Artemisia annua variety "Kehao No.1"].

As a natural plant source of artemisinin,a first-line drug against malaria,Artemisia annua directly affects the extraction process of artemisinin and the source of artemisinin. At present,traditional breeding methods combined with tissue culture are often used to breed high-yield artemisinin-containing new varieties of A. annua.

Anti-Müllerian Hormone Regulates Stem Cell Factor via cAMP/PKA Signaling Pathway in Human Granulosa Cells by Inhibiting the Phosphorylation of CREB.

Anti-Müllerian hormone (AMH) downregulates the level of stem cell factor (SCF) via the cAMP/PKA signaling pathway in human granulosa cells (GCs). Little information is available on the molecular mechanism underlying the interaction. This study is aimed at determining whether AMH regulates expression of SCF via the cAMP-PKA-CREB signaling pathway in human GCs.

[Seminal plasma anti-Müllerian hormone and inhibin B and serum inhibin B in predicting the outcome of routine IVF fertilization].

Objective: To analyze the correlations of seminal plasma (sp) anti-Müllerian hormone (spAMH) and inhibin B (spINHB) and serum INHB (serINHB) with semen parameters in oligoasthenospermia patients and explore their value in predicting the outcome of routine in vitro fertilization (IVF).

Methods: We obtained the levels of spAMH, spINHB and serINHB as well as semen parameters from 88 infertile males undergoing IVF due to oligoasthenospermia or female uterine tubal factors from August 2016 to February 2017. Using the ROC curve and Pearson's correlation analysis, we examined the effects of the obtained parameters on the fertilization rate and assessed the correlation of the levels of spAMH, spINHB and serINHB with the semen parameters of the patients.

Cinobufagin enhances the protective efficacy of formalin-inactivated Salmonella typhimurium vaccine through Th1 immune response.

Cinobufagin (CBG), one active ingredient isolated from Venenum Bufonis, has been demonstrated to have immunoregulatory effect. The aim of this study was to investigate whether CBG can enhance the protective efficacy of formalin-inactivated Salmonella typhimurium (FIST) in mice. ICR mice were immunized with FIST (10 CFU/mouse) alone or mixed with CBG (10, 20, and 40 μg) or alum (200 μg) on day 1 and day 15.

Autoinducer-2 of quorum sensing is involved in cell damage caused by avian pathogenic Escherichia coli.

Avian pathogenic Escherichia coli (APEC) infections are responsible for great losses in the poultry industry. Quorum sensing (QS) acts as a global regulatory system that controls genes involved in bacterial pathogenesis, metabolism and protein biosynthesis. However, whether QS of APEC is related to cell damage has not been elucidated.

Subinhibitory concentrations of phloretin repress the virulence of Salmonella typhimurium and protect against Salmonella typhimurium infection.

Phloretin, a natural component of many fruits, exhibits anti-virulence effects and provides a new alternative to counter bacterial infection. The aim of this study was to determine the effect of subinhibitory concentrations of phloretin on the virulence of Salmonella typhimurium. At concentrations where growth of Salmonella was not inhibited, phloretin significantly inhibited bacteria biofilm formation and motility.

Astragaloside IV Inhibits the Inflammatory Injury of Chicken Type II Pneumocytes Induced by Avian Pathogenic Escherichia coli.

Avian pathogenic Escherichia coli (APEC) induces septicemia in chickens by invading type II pneumocytes after breaching the blood-air barrier. Type II pneumocytes play an important role in maintaining the function of the blood-air barrier. Astragaloside IV has been shown in previous studies to have an anti-inflammatory effect.

Andrographolide interferes quorum sensing to reduce cell damage caused by avian pathogenic Escherichia coli.

Avian pathogenic Escherichia coli (APEC) induce septicemia in chickens by invading type II pneumocytes to breach the blood-air barrier. The virulence of APEC can be regulated by quorum sensing (QS). Andrographolide is a QS inhibitor of Pseudomonas aeruginosa (P.

Effects of breakfast with different calorigenic amounts on blood glucose, insulin and glucagon levels.

This study was aimed to investigate the relationship between breakfast and serum glucose, insulin and glucagon concentrations in order to establish a model breakfast appropriate for Chinese. Twenty-four volunteers were randomly assigned to four study groups: high carbohydrate breakfast, high fat and protein breakfast, the typical breakfast and fasting. Each subject had serum and urine samples collected while fasting and at 1,2 and 3.
