Rice straw-derived chitosan-enhanced plasticizers as biologically and environmentally friendly alternatives for sustainable materials. Int J Biol Macromol 2024; 264:130547. [PMID: 38431012 DOI: 10.1016/j.ijbiomac.2024.130547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/22/2024] [Accepted: 02/28/2024] [Indexed: 03/05/2024]
Abstract
Plasticizers like Bis(2-ethylhexyl)phthalate (DEHP) are commonly used to enhance plastic properties but pose environmental and health risks. This study successfully derived plasticizers X and Y from rice straws, demonstrating efficacy in chitosan polymer coatings. Chitosan-based polymers exhibit exceptional hardness, with a value of 300 MPa, due to their enriched structure and robust chitosan bonding. This surpasses the hardness of DEHP. Zebrafish exposure over 5 days revealed that X and Y had no significant behavioral impact, while DEHP caused noticeable toxic effects. Maternal DEHP exposure reduced placental cell growth, unlike X and Y, which had no adverse effects on uterine differentiation or placenta formation, suggesting their safety in human pregnancy. The successful development of X and Y represents a crucial step towards greener plasticizers, addressing environmental concerns and promoting safer alternatives in various industries.

Saudi Med J 2022; 43:694-699. [PMID: 35831000 PMCID: PMC9749698 DOI: 10.15537/smj.2022.43.7.20220283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 06/15/2022] [Indexed: 11/16/2022] Open
Abstract
OBJECTIVES To elucidate the link between fetuin-A expression in human umbilical vein endothelial cells (HUVECs) and amnion cells (ACs) and clinicopathological changes in patients with gestational diabetes mellitus (GDM) and newborns. METHODS This retrospective cohort study included 82 pregnant patients (40 with GDM and 42 controls) between January 2019 and January 2022. The patients underwent a one-hour, 50 gram glucose challenge test (GCT) during the 24-28th weeks of pregnancy. Patients with positive GCTs immediately underwent a 3-hour, 100 gram oral glucose tolerance test. The expression level of fetuin-A in UVECs and ACs was evaluated by immunohistochemistry (IHC) and scored based on IHC staining in randomly selected slides. The IHC staining intensity was evaluated by the number of dots, which reflects the expression level of fetuin-A in both HUVECs and ACs. RESULTS The GDM group displayed significantly higher fetuin-A expression in both HUVECs (p<0.0001) and ACs (p=0.0001) when compared with the control group. Fetuin-A expression in HUVECs was correlated with fetal macrosomia, neonatal hypoglycemia, and placental weight. However, there was no correlation with fetuin-A expression in ACs. CONCLUSION There is a correlation between fetal macrosomia, neonatal hypoglycemia, placental weight, and fetuin-A expression of HUVECs in patients with GDM.

Platelet-derived growth factor-AA promotes placental choriocarcinoma JAR cell proliferation via primary cilia. Taiwan J Obstet Gynecol 2022; 61:299-305. [PMID: 35361391 DOI: 10.1016/j.tjog.2022.02.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/09/2020] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE During early pregnancy, the proliferation placental cells is crucial for proper implantation and formation of maternal-fetal circulation. Platelet-derived growth factor-AA (PDGF-AA) has been detected in placenta during early pregnancy; however, the role of PDGF-AA in placental cell growth has not been studied extensively. Primary cilium, a centrosome-based cellular protrusion, is an signaling hub for regulating development and differentiation. Importantly, the receptor of PDGF-AA (Pdgfr-α) is detected in the primary cilium and primary cilia-mediated PDGF-AA signaling regulates development and differentiation. Here we would like to investigate whether PDGF-AA regulates placental cell growth and whether primary cilia play roles in this process. MATERIALS AND METHODS Human placental choriocarcinoma JAR cells were treated with PDGF-AA followed by examining cell growth. Primary cilia and subcellular localization of Pdgfr-α were observed by immunofluorescence staining. Manipulation of primary cilia was performed by treating cells with roscovitine or by transfecting cells with siRNA against IFT88. RESULTS Here we showed that PDGF-AA induced JAR cell proliferation. In addition, JAR cells grew primary cilia where Pdgfr-α was detected. More importantly, pharmacological inhibition of primary cilia formation or depletion of cilia-related gene, IFT88, alleviated PDGF-AA induced JAR cell proliferation. CONCLUSION Thus, our study show that PDGF-AA facilitates human placental choriocarcinomaJARcell growth via primary cilia.

J Obstet Gynaecol Res 2022; 48:178-187. [PMID: 34708901 DOI: 10.1111/jog.15070] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Revised: 10/05/2021] [Accepted: 10/06/2021] [Indexed: 11/27/2022]
Abstract
AIM We aimed to investigate the value of follicular fluid fetuins-A and -B to predict successful IVF and pregnancy outcomes in infertile women with poor, normal, and high ovarian reserve. METHODS The follicular fluid of 96 infertile women who underwent intra-cytoplasmic sperm injection (ICSI) procedure was analyzed. Fetuins-A and -B levels were examined and compared in those who could achieve pregnancy and those who could not. Receiver operating characteristic curve analyzes were used to determine cut-off and statistically significant associations for fetuins-A and -B. RESULTS Follicular fluid fetuin-A levels were higher in cases with weak ovarian reserve (OR) (p < 0.05) and higher in patients who did not achieve clinical pregnancy (p < 0.05). Conversely, the follicular fluid fetuin-B levels were lower in cases with poor OR (p < 0.05) and were lower in patients who did not achieve a clinical pregnancy (p < 0.05). A follicular fluid fetuin-A concentration ≤ 19.12 ng/mL had a sensitivity and specificity of 94.74% and 93.1%, respectively, at predicting clinical pregnancy. While the follicular fluid fetuin-B concentration >24.7 ng/mL had sensitivity and specificity of 71.1% and 51.7%, respectively, for clinical pregnancy prediction. CONCLUSION Overall, high levels of follicular fluid fetuin-A may be independently associated with unsuccessful IVF irrespective of OR grouping. A low level of follicular fetuin-B was also associated with failed IVF. The sensitivity and specificity were found to be higher for fetuin-A in predicting clinical pregnancy. Therefore, the follicular fluid fetuin-A may be more predictive for successful IVF and clinical pregnancy outcomes than follicular fluid fetuin-B.

Int J Mol Sci 2020; 21:ijms21093298.

Abstract
Placental homeostasis is directly linked to fetal well-being and normal fetal growth. Placentas are sensitive to various environmental stressors, including hypoxia, endoplasmic reticulum stress, and oxidative stress. Once placental homeostasis is disrupted, the placenta may rebel against the mother and fetus. Autophagy is an evolutionally conservative mechanism for the maintenance of cellular and organic homeostasis. Evidence suggests that autophagy plays a crucial role throughout pregnancy, including fertilization, placentation, and delivery in human and mouse models. This study reviews the available literature discussing the role of autophagy in preeclampsia.
