RESUMO

Soybean root rot is a worldwide soil-borne disease threatening soybean production, causing large losses in soybean yield and quality. Fusarium species are the most detrimental pathogens of soybean root rot worldwide, causing large production losses. Fusarium root rot has been frequently reported in Heilongjiang Province of China, but the predominant Fusarium species and the sensitivity of these pathogens to different fungicides remain unclear. In this study, diseased soybean roots were collected from 14 regions of Heilongjiang province in 2021 and 2022. A total of 144 isolates of Fusarium spp. were isolated and identified as seven distinct species: F. scirpi, F. oxysporum, F. graminearum, F. clavum, F. acuminatum, F. avenaceum, and F. sporotrichioide. F. scirpi and F. oxysporum had high separation frequency and strong pathogenicity. The sensitivity of Fusarium spp. to five different fungicides was determined. Mefentrifluconazole and fludioxonil showed good inhibitory effects, and the sensitivity to pydiflumetofen and phenamacril varied between Fusarium species. In particular, the activity of DMI fungicide prothioconazole was lower than that of mefentrifluconazole. Molecular docking showed that mefentrifluconazole mainly bound to CYP51C, but prothioconazole mainly bound to CYP51B. Furthermore, the sensitivity to prothioconazole only significantly decreased in ΔFgCYP51B mutant, and the sensitivity to mefentrifluconazole changed in ΔFgCYP51C and ΔFgCYP51A mutants. The results demonstrated that the predominant Fusarium species causing soybean root rot in Heilongjiang province were F. scirpi and F. oxysporum and DMI fungicides had differences in binding cavity due to the diversity of CYP51 proteins in Fusarium.

RESUMO

Atmospheric heavy metal pollution presents a severe threat to public health and environmental stability. Transition metal catalysts have emerged as a potent solution for the selective capture and removal of these pollutants. This review provides a comprehensive summary of current advancements in the field, emphasizing the efficiency and specificity of nanostructured transition metals, including manganese, iron, cobalt, nickel, copper, and zinc. Looking forward, we delve into the prospective trajectory of catalyst development, underscoring the need for materials with enhanced stability, regenerability, and environmental compatibility. We project that advancements in computational materials science, nanotechnology, and green chemistry will be pivotal in discovering innovative catalysts that are economically and environmentally sustainable. The integration of smart technologies for real-time monitoring and adaptive control is anticipated to revolutionize heavy metal remediation, ensuring efficient and responsive pollution abatement strategies in the face of evolving industrial scenarios and regulatory landscapes.

RESUMO

BACKGROUND: To identify the genetic risk of six genetic variants at 8q21 and 8q24 (including rs1512268, A; rs12543663, C; rs10086908, C; rs1016343, T; rs13252298, A, and rs6983561, C) associated with prostate cancer in Beijing and Tianjin (Jing-jin) area residents in northern China. METHODS: 574 subjects were enrolled. Blood samples and clinical information were collected from histologically confirmed prostate cancer cases (n = 286) and clinically evaluated matched normal controls (n = 288) from Chinese men in northern China. Six SNPs at 8q21 and 8q24 were genotyped by high-resolution melt and sequencing in subjects. We compared statistical differences between the prevalence of risk genotypes with prostate cancer in cases and controls and analyzed the association between clinical covariates and risk loci in case groups to infer their relationship with aggressive prostate cancer. RESULTS: Three genotypes of rs10086908, CC (OR = 2.48; 95% CI = 1.02 - 5.98, p = 0.037) rs1016343, TT (OR = 1.64, 95% CI = 1.07 - 2.53, p = 0.023); and rs6983561, CC (OR = 1.91; 95% CI = 1.09 - 3.63, p = 0.044) at 8q24 were identified to be associated with prostate cancer risk in Jing-jin Chinese. The D' values of both two-locus haplotypes (T-A: rs1016343 vs. rs13252298; T-C: rs1016343 vs. rs6983561) were 0.907 and 0.859, respectively, the three-locus haplotype, only TAC constituted by the loci (rs1016343, T; rs13252298, A; rs6983561, C) was also associated with prostate cancer (p = 0.033), revealing rs1016343 vs. rs6983561 with significant differences between cases and controls. According to clinical covariates and odds ratios of risk genotypes relative to non-risk genotypes, rs6983561, CC was associated with age (OR = 2.5; 95% CI = 1.02 - 6.13, p = 0.039), and tumor aggressiveness (OR = 1.15; 95% Cl = 1.06 - 1.23, p = 0.013). CONCLUSIONS: The loci including rs10086908, rs1016343, and rs6983561 at 8q24 could be associated with prostate cancer in Jing-jin residents in northern China. Our results suggest that these loci could influence susceptibility to prostate cancer in the northern Chinese population.

RESUMO

Liver fibrosis is a key pathological process shared by the progression of various chronic liver diseases. Treatment of liver fibrosis can effectively block the occurrence and development of hepatic cirrhosis or even carcinoma. Currently, there is no effective drug delivery vehicle for curing liver fibrosis. In this study, we designed matrine (MT)-loaded mannose 6-phosphate (M6P) modified human serum albumin (HSA) conjugated solid lipid nanoparticles (SLN), named M6P-HSA-MT-SLN for treatment of hepatic fibrosis. We demonstrated that M6P-HSA-MT-SLN exhibited controlled and sustained release properties and good stability over 7 days. The drug release experiments showed that M6P-HSA-MT-SLN exhibited slow and controlled drug release characteristics. In addition, M6P-HSA-MT-SLN showed a significant targeted ability to fibrotic liver. Importantly, in vivo studies indicated that M6P-HSA-MT-SLN could significantly improve histopathological morphology and inhibit the fibrotic phenotype. In addition, in vivo experiments demonstrate that M6P-HSA-MT-SLN could reduce the expression of fibrosis markers and alleviate the damage of liver structure. Hence, the M6P-HSA-MT-SLN provide a promising strategy to deliver therapeutic agents to fibrotic liver to prevent liver fibrosis.

RESUMO

We studied 6,023 individuals diagnosed with anemia on the basis of hematological examinations. The study showed that the frequency of α-thalassemia (α-thal) carriers was 26.9% and ß-thal carriers comprised 19.9% of the population of Guangxi Zhuang Autonomous Region, People's Republic of China (PCR). The diagnosed α-thal anomalies were related to six gene mutations and 16 genotypes, whereas the ß-thal were related to 10 gene mutations and 65 genotypes. The four most common mutations [codons 41/42 (-TTCT), codon 17 (A>T), -28 (A>G) and IVS-II-654 (C>T)] accounted for 86.38% of the ß-globin gene mutations. Risk analysis of mutation alleles in thalassemia cases identified four mutations (-α(3.7), -α(4.2), αα(Westmead) and αα(CS)) that were associated with α-thal intermedia, with an odds ratio (OR) of 62.41-32.68. Four high-risk mutations, namely, codon 26 (G>A), -28, codons 41/42 and codon 17, were associated with ß-thal major (ß-TM), with an OR of 3.93-2.20. The present study provides important genetic information on thalassemia in this population.

RESUMO

In European populations, 7 single nucleotide polymorphisms (SNPs) on chromosome 17q, 3 SNPs on 17q12, and 4 SNPs on 17q24.3 were recently identified to be closely related to the risk of prostate cancer by a genome-wide association study. In Japanese populations, the correlation between 2 SNPs on 17q and the risk of prostate cancer and tumor aggressiveness was also confirmed by a large-scale experiment. However, whether 17q is associated with prostate cancer and its clinical manifestations in Chinese populations is still unknown. Therefore, we conducted a case-control study in a northern Chinese population and tested 2 SNPs, rs4430796 and rs1859962, on 17q in 124 prostate cancer patients and 111 controls using polymerase chain reaction-high resolution melting curve (PCR-HRM) combined with sequencing. We analyzed the association of the 2 SNPs with the risk of prostate cancer as well as patients' lifestyles, onset ages, Gleason scores, PSA levels, and pathologic stages. We found a significant difference in the G allele of SNP rs1859962 (P = 0.035, OR = 1.51, 95% CI = 1.03-2.21) but not in the rs4430796 genotype frequency or allele frequency distribution between prostate cancer patients and the controls (P > 0.05). Neither of the SNPs was significantly associated with the onset age, Gleason score, PSA level, pathologic stage, or other clinical indicators of patients with prostate cancer (P > 0.05). Our results show that polymorphism of the G allele of SNP rs1859962 is associated with the risk of prostate cancer in a Chinese population.

RESUMO

OBJECTIVE: To investigate the correlation of the common variant single nucleotide polymorphisms (SNP) on chromosome 3 with the incidence and related risk factors of prostate cancer (PCa) in Chinese men. METHODS: Using the case-control meth- od, we included 124 PCa patients in the PCa group and 111 age- and gender-matched cancer-free healthy subjects as normal controls. We detected the distribution of allele and genotype frequencies of the SNP rs10934853 and rs2660753 with the polymerase chain reaction-high resolution melting curve (PCR-HRM) combined with gene sequencing, analyzed the cumulative effect of the risk genotypes of these two independent variants, and determined the correlation between different genotypes of these two SNPs and clinically related risk factors in the PCa patients. RESULTS: As for the genotypes of rs10934853, there were 28 cases of AA (22.8%), 46 cases of CC (37.4%), and 49 cases of AC (39.8%) in the PCa patients, as compared with 24 (22.0%), 34 (31.2%) and 51 (46.8%) in the healthy controls. As regards the genotypes of rs2660753, there were 13 cases of AA (11.0%), 59 cases of GG (50.0%) and 46 cases of AG (39.0%) in the PCa patients, in comparison with 9 (8.8%), 47 (45.6%) and 47 (45.6%) in the controls. No significant differences were found in the distribution of the genotype and allele frequencies of rs10934853 and rs2660753 between the two groups (P = 0.520 & 0.582). Analysis on the cumulative effect of the risk genotypes of rs10934853 and rs2660753 showed a slightly higher risk of PCa (OR = 1.831 & 1.968) in the two groups with risk genotypes than in the one with wild types (P > 0.05). Different genotypes of rs10934853 and rs2660753 were not correlated with clinically related risk factors of the PCa patients (P > 0.05). CONCLUSION: SNP rs10934853 and rs2660753 on chromosome 3 are not obviously correlated with PCa in Chinese patients, and may not be a genetic risk factor of PCa.

RESUMO

Healthy longevity has been an unremitting pursuit of human, but its genetic and the environment causes are still unclear. As longevity population is a good healthy aging model for understanding how the body begin aging and the process of aging, and plasma lipids metabolism and balance is a very important to life maintain and physiologic functional turnover. It is important to explore how the effect of genetic variants associated long-life individuals on lipids metabolism and balance. Therefore, we developed a comparative study based population which contains 2816 longevity and 2819 control. Through whole-exome sequencing and sanger sequencing genotypes, we identified four new single nucleotide polymorphisms of HLA-DQB1(major histocompatibility complex, class II, DQ beta 1), rs41542812 rs1049107 rs1049100 rs3891176(Prange=0.048-2.811×10-8 for allele frequencies), associated with longevity in Chinese Longevity Cohort. Further, by analysis of the longevity-variants linked to blood lipids, we identified HLA-DQB1 rs1049107, T-carriers (PHDL=0.006, OR: 11.277; PTG=9.095×10-7, OR: 0.025; PLDL/HDL=0.047, OR: 1.901) and HLA-DQB1 rs1049100, T-carriers (PTG=1.799×10-6, OR: 0.028) associated with lipid homeostasis in long lived individuals. Our finding showed that longevity and lipid homeostasis were associated with HLA-DQB1 and suggested that immune gene variants could act on both new function of maintaining the homeostasis and anti-aging in longevity.

RESUMO

Current evidence shows that apolipoprotein E (APOE), apolipoprotein CI (APOC1) and low density lipoprotein receptor-related protein (LRP) variations are related to late-onset Alzheimer's disease. However, it remains unclear if genetic polymorphisms in these genes are associated with cognitive decline in late-onset Alzheimer's disease patients. We performed a 30-month longitudinal cohort study to investigate the relationship between Alzheimer's disease and APOE, APOC1, and LRP. In this study, 78 Chinese Han patients with late-onset Alzheimer's disease were recruited form Guangxi Zhuang Autonomous Region in China. APOE, APOC1, and LRP genotyping was performed using polymerase chain reaction-restriction fragment length polymorphisms. The Mini-Mental State Examination and Clinical Dementia Rating Scale were used to assess patients' cognitive function. After a 30-month follow-up period, we found a significant reduction in Mini-Mental State Examination total score, a higher proportion of patients fulfilling cognitive impairment progression criteria, and a higher proportion of APOC1 H2 carriers in APOE ε4 carriers compared with non-carriers. In addition, the APOE ε4 allele frequency was significantly higher in the cognitive impairment progression group compared with the non-cognitive impairment progression group. In conclusion, APOE ε4 plays an important role in augmenting cognitive decline, and APOC1 H2 may act synergistically with APOE ε4 in increasing the risk of cognitive decline in Chinese patients with late-onset Alzheimer's disease.

RESUMO

AIMS: Genome-wide association studies (GWAS) have identified several risk variants for prostate cancer (pCa) mainly in Europeans, which need to be further verified in other racial groups. We selected six previously identified variants as candidates and to define the association with PCa in Northern Han Chinese. METHODS: 749 subjects from Beijing and Tianjin in Northern China were included. Six variants (rs10505474, rs7837328, rs4242384, rs7813, rs486907 and rs1058205) were genotyped by high resolution melting (HRM) assays. The individual and cumulative contribution for of the risk of PCa and clinical covariates were analyzed. RESULTS: Among the six candidate variants, only rs10505474, and rs7837328, both locating at 8q24 region, were associated with PCa in our population.rs10505474 (A) was associated with PCa (ORrecessive= 1.56, p=0.006); and rs7837328 (A) was associated with PCa (ORdominant= 1.38, p=0.042/ORrecessive=1.99, p=0.003). Moreover, we observed a cumulative effects between them (ptrend=2.58?10-5). The joint population attributable risk showed the two variants might account for 71.85% of PCa risk. In addition, we found the homozygotes of rs10505474 (A) and rs7837328 (A) were associated with PCa clinical covariants (age at onset, tumor stage, respectively) (page=0.046, Ptumorstage =0.048). CONCLUSION: rs10505474 (A) and rs7387328 (A) at 8q24 are associated with PCa and cumulatively confer risk, suggesting the two variations could determine susceptibility to PCa in the Northern Chinese Han population.

RESUMO

BACKGROUND: The single nucleotide polymorphism (SNP) rs1465618 in THADA at 2p21 has been identified as being associated with prostate cancer (PCa) risk in Europeans; however, it is not clear whether the SNP is related to PCa risk in multiple populations. We investigated the association of rs1465618 in THADA with PCa in a Chinese population and carried out a meta-analysis in multiple populations, testing the relevance of this SNP for PCa risk. PATIENTS AND METHODS: We genotyped the SNP using high resolution melting (HRM) analysis and assessed its association with PCa risk in a case-control study of 289 PCa patients and 288 controls in a Chinese population. A meta-analysis was carried out with 36,313 PCa patients and 36,485 controls to evaluate the association of rs1465618 with PCa risk in multiple populations. RESULTS: rs1465618 in THADA was significantly associated with PCa risk (p = 0.026; odds ratio (OR) 1.327, 95% confidence interval (CI) 1.035-1.700). Furthermore, the rs1465618 variant genotype was associated with PCa aggressiveness (p = 0.044; OR = 2.053, 95% CI = 1.015-6.602) in the Chinese population. The meta-analysis showed that rs1465618 was significantly associated with PCa risk in multiple populations (p = 1.0×10(-8); OR = 1.127, 95% CI = 1.085-1.171). CONCLUSION: Our results showed that rs1465618 in THADA may be a shared susceptibility variant for PCa in multiple populations. THADA gene polymorphisms may impact PCa susceptibility and progression.

RESUMO

BACKGROUND: Evidence supporting an association between the 8q24 rs4242382-A polymorphism and prostate cancer (PCa) risk has been reported in North American and Europe populations, though data from Asian populations remain limited. We therefore investigated this association by clinical detection in China, and meta-analysis in Asian, Caucasian and African-American populations. MATERIALS AND METHODS: Blood samples and clinical information were collected from ethnically Chinese men from Northern China with histologically- confirmed PCa (n=335) and from age-matched normal controls (n=347). The 8q24 (rs4242382) gene polymorphism was genotyped by polymerase chain reaction-high-resolution melting analysis. We initially analyzed the associations between the risk allele and PCa and clinical covariates. A meta-analysis was then performed using genotyping data from a total of 1,793 PCa cases and 1,864 controls from our study and previously published studies in American and European populations, to determine the association between PCa and risk genotype. RESULTS: The incidence of the risk allele was higher in PCa cases than controls (0.222 vs 0.140, P=7.3?10-5), suggesting that the 8q24 rs4242382-A polymorphism was associated with PCa risk in Chinese men. The genotypes in subjects were in accordance with a dominant genetic model (ORadj=2.03, 95%CI: 1.42-2.91, Padj=1.1?10-4). Presence of the risk allele rs4242382-A at 8q24 was also associated with clinical covariates including age at diagnosis ≥65 years, prostate specific antigen >10 ng/ml, Gleason score <8, tumor stage and aggressive PCa, compared with the non-risk genotype (P=4.6?10-5-3.0?10-2). Meta-analysis confirmed the association between 8q24 rs4242382-A polymorphism and PCa risk (OR=1.62, 95%CI: 1.39-1.88, P=1.0?10-5) across Asian, Caucasian and African American populations. CONCLUSIONS: The replicated data suggest that the 8q24 rs4242382-A variation might be associated with increased PCa susceptibility in Asian, Caucasian and African American populations. These results imply that this polymorphism may be a useful risk biomarker for PCa in multi-ethnic populations.

RESUMO

BACKGROUND: Previous association studies examining the relationship between the APOC1 polymorphism and susceptibility to Alzheimer's disease (AD) have shown conflicting results, and it is not clear if an APOC1 variant acts as a genetic risk factor in AD etiology across multiple populations. METHODS: To confirm the risk association between APOC1 and AD, we designed a case-control study and also performed a meta-analysis of previously published studies. RESULTS: Seventy-nine patients with AD and one hundred fifty-six unrelated controls were included in case-control study. No association was found between the variation of APOC1 and AD in stage 1 of our study. However, our meta-analysis pooled a total of 2092 AD patients and 2685 controls. The APOC1 rs11568822 polymorphism was associated with increased AD risk in Caucasians, Asians and Caribbean Hispanics, but not in African Americans. APOE ε4 carriers harboring the APOC1 insertion allele, were more prevalent in AD patients than controls (χ(2) = 119.46, OR = 2.79, 95% CI = 2.31-3.36, P<0.01). CONCLUSIONS: The APOC1 insertion allele, in combination with APOE ε4, likely serves as a potential risk factor for developing AD.

RESUMO

OBJECTIVE: Adiponectin receptor 1 (encoded by ADIPOR1) is one of the major adiponectin receptors, and plays an important role in glucose and lipid metabolism. However, few studies have reported simultaneous associations between ADIPOR1 variants and type 2 diabetes (T2D), coronary artery disease (CAD) and T2D with CAD. Based on the "common soil" hypothesis, we investigated whether ADIPOR1 polymorphisms contributed to the etiology of T2D, CAD, or T2D with CAD in a Northern Han Chinese population. METHODS: Our multi-disease comparison study enrolled 657 subjects, including 165 with T2D, 173 with CAD, 174 with both T2D and CAD (T2D+CAD), and 145 local healthy controls. Six ADIPOR1 single nucleotide polymorphisms (SNPs) were genotyped and their association with disease risk was analyzed. RESULTS: Multi-case-control comparison identified two ADIPOR1 variants: rs3737884-G, which was simultaneously associated with an increased risk of T2D, CAD, and T2D+CAD (P-value range, 9.80×10(-5)-6.30×10(-4); odds ratio (OR) range: 1.96-2.42) and 16850797-C, which was separately associated with T2D and T2D+CAD (P-value range: 0.007-0.014; OR range: 1.71-1.77). The risk genotypes of both rs3737884 and 16850797 were consistently associated with common metabolic phenotypes in all three diseases (P-value range: 4.81×10(-42)-0.001). We observed an increase in the genetic dose-dependent cumulative risk with increasing risk allele numbers in T2D, CAD and T2D+CAD (P trend from 1.35×10(-5)-0.002). CONCLUSIONS: Our results suggest that ADIPOR1 risk polymorphisms are a strong candidate for the "common soil" hypothesis and could partially contribute to disease susceptibility to T2D, CAD, and T2D with CAD in the Northern Han Chinese population.

RESUMO

BACKGROUND: KLK3 gene products, like human prostate-specific antigen (PSA), are important biomarkers in the clinical diagnosis of prostate cancer (PCa). G protein-coupled receptor RFX6, C2orf43 and FOXP4 signaling plays important roles in the development of PCa. However, associations of these genes with PCa in northern Chinese men remain to be detailed. This study aimed to investigate their impact on occurrence and level of malignancy. METHODS: All subjects were from Beijing and Tianjin, including 266 cases with prostate cancer and 288 normal individuals as controls. We evaluated associations between clinical covariates (age at diagnosis, prostate specific antigen, Gleason score, tumor stage and aggressive) and 6 candidate PCa risk loci, genotyped by PCR- high resolution melting curve and sequencing methods. RESULTS: Case-control analysis of allelic frequency of PCa associated with PCa showed that one of the 6 candidate risk loci, rs339331 in the RFX6 gene, was associated with reduced risk of prostate cancer (odds ratio (OR) = 0.73, 95% confidence interval (CI) =0.57-0.94, P = 0.013) in northern Chinese men. In addition, subjects with CX (CC+TC) genotypes had a decreased risk for prostrate cancer compared to those carrying the TT homozygote (OR =0.64, 95% CI = 0.45- 0.90, P = 0.008). The TT genotype of 13q22 (rs9600079, T) was associated with tumor stage (P=0.044, OR=2.34, 95% CI=0.94-5.87). Other SNPs were not significantly associated with clinical covariates in prostate cancer (P > 0.05). CONCLUSIONS. rs339331 in the RFX6 gene may be associated with prostate cancer as a susceptibility locus in northern Chinese men.

RESUMO

BACKGROUND/AIM: Six prostate cancer (PCa) susceptibility loci were identified in a genome-wide association study (GWAS) in populations of European decent. However, the associations of these 6 single-nucleotide polymorphisms (SNPs) with PCa has remained tobe clarified in men in Northern China. This study aimed to explore the loci associated with PCa risk in a Northern Chinese population. METHODS: Blood samples and clinical information of 289 PCa patients and 288 controls from Beijing and Tianjin were collected. All risk SNPs were genotyped using polymerase chain reaction (PCR)-high resolution melting curve technology and gene sequencing. Associations between PCa and clinical covariates (age at diagnosis, prostate-specific antigen [PSA], Gleason score, tumor stage, and level of aggressiveness) and frequencies of alleles and genotypes of these SNPs were analyzed using genetic statistics. RESULTS: Among the candidate SNPs, 11p15 (rs7127900, A) was associated with PCa risk (P = 0.02, odds ratio [OR] = 1.64, 95% confidence interval [CI] = 1.09-2.46). Genotypes showed differences between cases and controls on 11p15 (rs7127900, A), 11q13 (rs7931342, T), and HNF1B (rs4430796, A) (P = 0.03, P = 0.01, and P = 0.04, respectively). The genotype TG on 11q13 (rs7931342, T) was positively associated with an increased Gleason score (P = 0.04, OR = 2.15, 95% CI = 1.02-4.55). Patients carrying TG on 17q24 (rs1859962, G) were negatively associated with an increased body mass index (BMI) (P = 0.03, OR = 0.44, 95% CI = 0.21-0.92) while those with AG on HNF1B (rs4430796, A) were more likely to have PSA increase (P = 0.002). CONCLUSION: Our study suggests that 11p15 (rs7127900, A) could be a susceptibility locus associated with PCa in Northern Chinese. Genotype TG on 11q13 (rs7931342, T) could be related to an increased Gleason score, AG on HNF1B (rs4430796, A) could be associated with PSA increase, and TG on 17q24 (rs1859962, G) could be negatively associated with an increased BMI in Chinese men with PCa.
