Article Abstract
Objective: To study the effects of PDGF-Rb antagonists imatinib on endometrial injury repairing in the mouse model.
Methods: The cultured MSCs cells from male mice were marked with BrdU in vitro, and then transplanted to the female mice which suffered from radiation injury through tail vein, PDGF-Rb antagonists imatinib was injected through abdominal cavity. Four groups were arranged, which were radiation transplantation group, normal control group, imatinib intervention group and radiation control group. BrdU incorporation, SRY expression and MVD status were detected in uterus of mice.
Results: SRY gene was negative expressed in normal control group and radiation control group. SRY gene presented positive in radiation transplantation group and imatinib intervention group; BrdU incorporation showed negative in radiation control group and normal control group which died in the early stage in mice; the incorporation of BrdU was higher in radiation transplantation group compared with imatinib intervention group; CD34 was positive on the uterus of all the four groups, which showed highest in radiation control group and lowest in radiation control group; The MVD in imatinib intervention group was lower than radiation control group; the difference of MVD was significantly compared with normal control group (P < 0.05).
Conclusions: PDGF-Rb antagonists imatinib could inhibit the repairing function of MSCs in the endometrial lesions in mice.

Background: Children in low- and middle-income countries face obstacles to optimal language and cognitive development due to a variety of factors related to adverse socioeconomic conditions. One of these factors is compromised caregiver-child interactions and associated pressures on parenting. Early development interventions, such as dialogic book-sharing (DBS), address this variable, with evidence from both high-income countries and urban areas of low- and middle-income countries showing that such interventions enhance caregiver-child interaction and the associated benefits for child cognitive and socioemotional development.

Background: Various media are used to enhance public understanding about diseases. While mobile health apps are widely used, there is little proof for using such apps to raise awareness of skin diseases.
Objective: We intend to develop an app, called DEDIKASI-app, to raise awareness of skin diseases, including leprosy.

l-glufosinate has garnered increasing attention as an ideal herbicide for weed control in agriculture. However, the underlying racemization process of l-glufosinate in the aqueous phase remains unclear. In this work, we elucidated the racemization mechanisms through heating reactions and theoretical calculations.

Pesticides are widely used to meet the food demands of a growing population, with various types used to control pests depending on the crops grown. Rainfall, overspray, and runoff from agricultural fields can wash these insecticides into water bodies, posing documented environmental risks. Imidacloprid is commonly used in Afrotropical regions such as South Africa, yet limited information is available on its toxicity to aquatic ecosystems within this climate region.

Importance: Previous studies have suggested that social participation helps prevent depression among older adults. However, evidence is lacking about whether the preventive benefits vary among individuals and who would benefit most.
Objective: To examine the sociodemographic, behavioral, and health-related heterogeneity in the association between social participation and depressive symptoms among older adults and to identify the individual characteristics among older adults expected to benefit the most from social participation.
