ABSTRACT

Based on the research methods of literature review and philosophical reflection, this article points out the deficiencies and problems in the current research of brain banks: lack of nature analysis of brain banks and human brains; insufficient discussion of ethical, legal and social issues (ELSI) in the process of brain bank implementation - which has become the main research goal of this article. The article firstly clarifies the formation process of modern brain banks and briefly introduces the current development status of brain banks in the UK, the US and China, as well as the different types of modern brain banks. Next, the nature of brain banks and human brain samples are analyzed through an analogical model. Then, the ELSI issues at different stages are analyzed according to three stages: recruitment of donors, acquisition and storage of human brain tissue samples, and release and use of human brain tissue samples. Last, in the conclusion section, the main ideas of this paper are reiterated and questions for further reflection are presented.

ABSTRACT

OBJECTIVE: To explore the potential correlation between heat shock protein 60 (HSP60) gene polymorphisms and susceptibility to atherosclerosis. PATIENTS AND METHODS: A total of 160 atherosclerosis patients treated in our hospital from February 2017 to February 2019 were randomly enrolled as case group, and 200 healthy adults receiving physical examination were selected as control group at the same period. Venous blood was drawn from all subjects to extract deoxyribonucleic acid (DNA). TaqMan probe technology was employed to genotype two loci rs2340690 and rs788016 of HSP60 gene in all 260 subjects. The correlations between HSP60 gene polymorphisms and the incidence rate and pathological grade of atherosclerosis were analyzed. RESULTS: There were three genotypes (AA, AG, and GG) in HSP60 rs2340690 and three (GG, AG, and AA) in HSP60 rs788016. No significant differences in the frequency of each genotype were found between the two groups (p>0.05). HSP60 rs2340690 and HSP60 rs788016 had no significant associations with the incidence rate of atherosclerosis in the dominant, recessive, and additive genetic models. In the case of pathological grade IV, the proportion of atherosclerosis patients carrying GG genotype of HSP60 rs2340690 was higher than those carrying AA genotype and AG genotype of HSP60 rs2340690 (p<0.05). The probability in atherosclerosis patients carrying rs788016 A was higher than those carrying rs2340690 G (p<0.05). When atherosclerosis patients carried both genotype G of HSP60 rs2340690 and genotype A of HSP60 rs788016, the odds ratio (OR) was 1.721 (p=0.049). CONCLUSIONS: The HSP60 gene polymorphisms are certainly correlated with the pathological grade and incidence rate of atherosclerosis.

ABSTRACT

AKT1, also known as v-akt murine thymoma viral oncogene homolog 1, is involved in the regulation of cell-survival and anti-apoptotic activities, which may affect the pathogenesis of various cancers. However, the association between genetic variants of AKT1 and the risk of developing prostate cancer has not been investigated before. This study investigated the associations between three polymorphisms (rs1130214, rs3730358, and rs2494732) in AKT1 and the risk of development of prostate cancer in the Chinese Han population. Sequenom MassARRAY & iPLEX technology were used to genotype these polymorphisms in 493 Chinese Han patients with prostate cancer and 309 age-matched healthy individuals. Compared to the CC genotype of the rs3730358 polymorphism, the CT genotype of the same polymorphism was strongly associated with a decreased risk of prostate cancer (OR = 0.617, 95%CI = 0.390-0.976, P = 0.037). However, there was no significant difference between the allele frequency of the rs3730358 polymorphism and those of the other two polymorphisms (P > 0.05). Moreover, no significant difference was found in the haplotype analysis (P > 0.05). Our study found that the variant genotype CT of rs3730358 of AKT1 was associated with a decreased risk of prostate cancer, which suggested that this polymorphism could play an important role in the development of the disease.

ABSTRACT

The purpose of this study is to develop the design equation of a laminar-falling-film-slurry-type (LFFS) photoreactor for the treatment of organic wastewaters (Acid Red 4) by 185 nm vacuum ultra-violet (VUV) related processes. The LFFS photoreactor is one of the most efficient reactor configurations for conducting heterogeneous photocatalytic reactions, particularly for wastewater treatment. The decomposition of Acid Red 4 dye wastewaters by VUV-based photo-oxidation process was studied under various UV light intensities, dosages of H2O2 and TiO2. By the treatment of the LFFS-VUV only process, it was found that the decomposition rates of the dye in aqueous solutions increased with the increasing of VUV light intensity, dosage of TiO2, dosage of H2O2. The apparent potential of OH. generation from the photolysis of used oxidants (i.e. OH. sources, H2O, H2O2, TiO2) to decompose the targeted dye wastewater was investigated and compared.
