Developmental and neurotoxic effects of dimethyl phthalate on zebrafish embryos and larvae.

Dimethyl phthalate (DMP) has been extensively utilized as a plasticizer on a global scale for many years. Its presence in the environment and its harmful effects on living organisms have raised concerns. This study aimed to examine its potential developmental neurotoxicity by utilizing zebrafish as a model.

[Effects of on Proliferation, Migration and Invasion of Acute Myeloid Leukemia Cells by Regulating /HOXA9 Axis].

Objective: To explore the effects and molecular mechanism of on the proliferation, migration and invasion of acute myeloid leukemia (AML) cells.

Methods: Bone marrow samples from 35 pediatric AML patients and 35 healthy controls in Henan Provincial Children's Hospital from April 2015 to April 2017 and human bone marrow stromal cell lines (HS-5) and AML cell lines (HL-60, THP-1, U-937 and Kasumi-1) were collected. The expressions of and homeobox A9 (HOXA9) in bone marrow samples and cells were detected by RT-qPCR and Western blot.

[Effect of breastfeeding on immune function in infants with human cytomegalovirus infection].

Objectives: To study the effect of breastfeeding on immune function in infants with human cytomegalovirus (HCMV) infection.

Methods: A retrospective analysis was performed on the medical data of 135 infants with HCMV infection who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2021 to May 2022, and all these infants received breastfeeding. According to the results of breast milk HCMV-DNA testing, the infants were divided into two groups: breast milk HCMV positive (=78) and breast milk HCMV negative (=57).

Encapsulating N‑doped graphite carbon in MoO as a novel cocatalyst for boosting photocatalytic hydrogen evolution.

Generally, it is important to ameliorate the co-catalyst used in photocatalytic hydrogen evolution reactions (PHERs) to achieve efficient transfer and separation of photogenerated carriers, decrease the surface reaction energy barrier, and hence improve the photocatalytic activity. In this study, N-doped graphite carbon (GC) was introduced in situ to MoO to ensure the presence of well-dispersed active sites, lower the overpotential of hydrogen evolution, and further achieve high conductivity. Then, the MoO/GC composite obtained was used as a co-catalyst of ZnInS (ZIS) in a PHER, resulting in a great improvement in the photocatalytic activity.
