Abstract

Benzo(a)pyrene (BaP) is an environmental pollutant widely exposed to human beings. While the relationship between BaP and missed abortion is few understood. To explore the association between missed abortion and BaP, genetic polymorphisms of AhR pathway, we recruited 112 cases women with missed abortion and 137 controls women with normal pregnancy from Shanxi, China. The BPDE-DNA adducts level in the case group was higher than that in the control group (P < 0.001). The subjects were categorized according to the tertiles of BPDE-DNA adduct concentrations: T1 (33), T2 (P33~P67) and T3 (≥P67), the results suggested that the risk of missed abortion at T2 and T3 levels were 5.68 times (P = 0.009), 6.17 times (P = 0.001) higher than that of T1 level, respectively. The interaction between ALDH3A1 rs887241 and BPDE-DNA adducts was indicated. These findings show that BaP exposure may affect the risk of missed abortion, and genetic polymorphisms may change the susceptibility to BaP. [ABSTRACT FROM AUTHOR]

16. Aggressive Intestinal Symptoms Caused by Metastatic Tumors Originating from Primary Gastric Cancer in Pregnancy: A Case Report

Author

Abstract

Gastric carcinoma is extremely rare in pregnancy and the prognosis for this malignancy tends to be dismal. We herein describe a case of gastric cancer in pregnancy to alert clinicians to this rare possibility. A 29-year-old woman developed abdominal spastic pain and diarrhea during the 26 weeks of gestation and her condition was confusing and hard to recognize. The patient was initially misdiagnosed as enterogastritis and inflammatory intestinal obstruction and was finally confirmed by exploratory laparotomy with intestinal and peritoneum metastases. Because the disease was not detected early enough and progressed rapidly, the pregnancy was terminated by cesarean section at 30 weeks of gestation, and then followed by systemic chemotherapy, but eventually succumbed to the lethal pneumonia. Therefore, it is of great significance to alert clinicians to note this rare possibility and to consider the differential diagnosis of this disease in pregnant women with a long course of gastrointestinal symptoms that cannot be explained by pregnancy alone, and cancer should be suspected and tested with sophisticated diagnostic procedures.

Abstract

Easily oxidized group and rigid structure of phenolic resin (PR) network can result in brittleness and low char yield at high temperatures, which limits the widespread applications of PR in harsh environment. Whilst organic-inorganic hybrid material, such as POSS-containing material was introduced to enhance PR, the microstructure and the thermo-mechanical properties of the hybrid material modified PR are not well understood. Therefore, in the work, a novel organic-inorganic hybrid networks (ENH) were prepared with epoxy-polyhedral oligomeric silsesquioxane (EPOSS) modified novolac phenolic resin (EN) and hexamethylenetetramine (HMTA) to further clarify the curing behavior and its relation to microstructure and the resulting thermal-mechanical properties. Here, the curing characteristics of ENH were discussed by usinag advanced isoconversional method and Fourier transform infrared spectroscopy (FTIR). It was revealed that a diversity of crosslinking networks was exhibited after curing ENH, including EPOSS-NR crosslinked, tethered structure, and self-polymerized structure of EPOSS as well as NH networks. When the substitution degree of EPOSS is relatively low, EPOSS serves as a junction point to further improve the crosslinking density of ENH networks, leading to better thermo-mechanical properties, thermal stability and tensile property as well as lower dielectric properties. However, as the self-polymerization of EPOSS increased, the NH network was dramatically disrupted and the thermo-mechanical properties, thermal stability and tensile property of ENH were deteriorated.
