Background: The aetiology of Testicular Cancer (TC) is still unknown to researchers but many of the associated risk factors have been identified. These include family history, age, racial origin, cryptorchidism, urogenital malformations, testicular atrophy, and infertility. Given the lack of scientific data on the causes of the disease, it has been asserted in previous studies that the promotion of awareness and early detection are prerequisites to mitigating risks of metastasis as well as improving survival. This study is to assess the awareness, practice, and intention to practice testicular self-examination among professional working males in Accra. Methods: A quantitative cross-sectional design with a structured research instrument was used to collect data from respondants. The purposive and convenience sampling techniques were used to collect data from 300 men at Accra in Ghana. The study was conducted at two (2) Universities and a Senior High school at Accra in Ghana. The data was then analysed using descriptive statistics, logistic regression, multiple linear regression, and structural equation modeling. Results: From the study findings, 37% of male participants rated their knowledge of testicular self-examination and related symptoms as good, 28% of participants practised testicular self-examination monthly, while 65% of respondents expressed their intention to practice monthly testicular self-examination. The findings from logistic regression demonstrated that level of education, age, and marital status of participants had a significant influence on testicular self-examination. Additionally, the multiple linear regression results revealed knowledge and self-efficacy significantly predict testicular self-examination intention. The path coefficient results from the structural equation model are consistent with results from the regression models. Conclusion: This research is the first to investigate testicular self-examination among men in Ghana. The findings revealed awareness and practice of TSE are low among participants. Therefore, the research findings would improve the expertise of physicians and nurses in providing counsel, intervention, and support for patients at risk of testicular cancer. 展开更多

This paper introduces and analyzes Korea's NGV (natural gas vehicles) policy for soot-free bus fleet which intends to promote CNG (compressed natural gas) bus in metropolitan area for the reduction of air pollution from road sector. At the early stage, Korean goverrmaent established various supporting policy systems to encourage public transportation companies to purchase CNG buses as a means to replace diesel buses. It was evaluated as very successful with making net economic benefit of CNG bus promotion policy. During the 2nd stage, Korean government implemented CNG hybrid bus promotion policy to further reduce both air pollution and greenhouse gas. Now, a new social demand for the vehicles is zero-emission vehicles. The author asserts that current FCEV (fuel cell electric vehicle) should be considered as an alternative to zero-emission vehicles in Korea and suggests policy recommendation for the promotion of FCEV by referring the current CNG bus promotion policy in public transportation sector. 展开更多

Natural selection opposes the evolution of cooperation unless specific mechanisms are at work in Prisoner's Dilemma. By taking advantage of the modern control theory, the controller design is discussed and the optimal control is designed for promoting cooperation based on the recent advances in mechanisms for the evolution of cooperation. Two con- trol strategies are proposed: compensation control strategy for the cooperator when playing against a defector and reward control strategy for cooperator when playing against a coop- erator. The feasibility and effectiveness of these control strategies for promoting cooperation in different stages are analyzed. The reward for cooperation can't prevent defection from being evolutionary stable strategy (ESS). On the other hand, compensation for the coopera- tor can't prevent defection from emerging and sustaining. By considering the effect and the cost, an optimal control scheme with constraint on the admissible control set is put forward. By analyzing the special nonlinear system of replicator dynamics, the exact analytic solution of the optimal control scheme is obtained based on the maximum principle. Finally, the effectiveness of the proposed method is illustrated by examples. 展开更多

Background: Antibiotic growth promoters(AGPs) have been used as growth promoters to maintain animal intestinal health and improve feed efficiency in broilers by inhibiting pathogen proliferation. In view of the growing emergence of antibiotic-resistant pathogen strains and drug residue issues, novel treatments are increasingly required. This study aimed to compare two antimicrobial approaches for managing pathogen infection and maintaining animal intestinal health in broilers by supplying Apidaecin Api-PR19 and AGPs over 42 d of a feeding trial.Results: Compared with the broilers that were only fed a corn-soybean basal diet(CON group), supplementation with Api-PR19 and AGP(respectively named the ABP and AGP groups) both increased the feed conversion efficiency. When compared with the AGP group, Api-PR19 supplementation could significantly increase the organ index of the bursa of fabricius and subtype H9 antibody level in broiler chickens. Moreover, when compared with the CON group, the intestinal villus height, intestinal nutrient transport, and intestinal s Ig A content were all increased in the Api-PR19 group, while AGP supplementation was harmful to the intestinal villus height and intestinal nutrient transport. By assessing the antibacterial effect of Api-PR19 and antibiotics in vitro and in vivo, we found that Api-PR19 and antibiotics both inhibited the growth of pathogens, including Escherichia coli and Campylobacter jejuni. Furthermore, by using 16 S r RNA gene sequencing, the beneficial bacteria and microbiota in broilers were not disturbed but improved by apidaecin Api-PR19, including the genera of Eubacterium and Christensenella and the species of uncultured_Eubacterium_sp, Clostridium_asparagiforme, and uncultured_Christensenella_sp, which were positively related to improved intestinal development, absorption, and immune function.Conclusion: Apidaecin Api-PR19 treatment could combat pathogen infection and had little negative impact on beneficial bacteria in the gut compared to antibiotic treatment, subsequently improving intestinal development,absorption, and immune function. 展开更多

Malignant characteristics of Ewing’s sarcoma are correlated with expression of EWS oncogene. We achieved knockdown of EWS expression using a plasmid vector encoding EWS short hairpin RNA (shRNA) to increase anti-tumor mechanisms of taxifolin (TFL), a new flavonoid, in human Ewing’s sarcoma cells in culture and animal models. Immunofluorescence microscopy and flow cytometric analysis showed high expression of EWS in human Ewing’s sarcoma SK-N-MC and RD-ES cell lines. EWS shRNA plus TFL inhibited 80% cell viability and caused the highest decreases in EWS expression at mRNA and protein levels in both cell lines. Knockdown of EWS expression induced morphological features of differentiation. EWS shRNA plus TFL caused more alterations in molecular markers of differentiation than either agent alone. EWS shRNA plus TFL caused the highest decreases in cell migration with inhibition of survival, angiogenic and invasive factors. Knockdown of EWS expression was associated with removal of DNA methylation from p53 promoter, promoting expression of p53, Puma, and Noxa. EWS shRNA plus TFL induced the highest amounts of apoptosis with activation of extrinsic and intrinsic pathways in both cell lines in culture. EWS shRNA plus TFL also inhibited growth of Ewing’s sarcoma tumors in animal models due to inhibition of differentiation inhibitors and angiogenic and invasive factors and also induction of activation of caspase-3 for apoptosis. Collectively, knockdown of EWS expression increased various anti-tumor mechanisms of TFL in human Ewing’s sarcoma in cell culture and animal models. 展开更多

Background: The Health Promotion Model (HPM) indicates that each person is a biopsychosocial creature that is partially shaped by the environment, but also seeks to create an environment in which inherent and acquired human potential can be fully expressed. The HPM is proposed as a holistic predictive model of health-promoting behavior for use in research and practice. Purpose: The purpose of this review is to examine how the HPM has been applied in various research studies. Methods: An integrative review was used to find studies that were guided by the HPM. Data search was between 2008 to 2018 using Google Scholar, Scopus, Web of Science, Science Direct, PubMed, Medline, CINAHL, EBSCO, Cochrane, ERIC, Joanna Briggs Institute and EBSCO host. The keywords used were Pender’s and Health Promotion Model. Results: Seventeen studies were reviewed;most of them were quantitative studies. These studies discussed variables from the HPM. Most of the study variables were measured using instruments derived from the HPM. The results of the reviewed studies revealed that the HPM had predictive value in estimating health-promoting behaviors. Conclusion: The HPM was widely established in the nursing community and was implemented in nursing practice, education, and research. In addition, the HPM constructs were used to hypothesize conceptual frameworks in many studies to predict health-promoting behaviors in many chronic diseases. 展开更多

The ACE (angiotensin converting enzyme) inhibitors are not only drugs widely prescribed drugs in cardiovascular diseases, but also potentially therapeutic agents in dementia. Based on the findings that the ACE inhibitors could activate the c-Jun N-terminal kinase signal to increase the ACE gene expression and that the Alu element of the human ACE gene involved in regulating ACE promoter activity, we aimed to investigate whether there are different pharmacogenetic responses of ACE I/D polymorphism to the ACE inhibitors in neurons. The three reporter vectors, pACEpro(0-SEAP, p-I-ACEpro-SEAP, and p-D-ACEpro-SEAP were used to examine the transcriptional activity of the vectors responding to the lisinopril treatment using a transient-transfection method in SH-SY5Y cells. Our results showed that lisinopril increased the promoter activity of an ACE gene by 16.7%. Additionally, we found the lisinopril enhanced the ACE promoter activity of the I-form vector by 17.2%, but adversely reduced that of the D-form vector by 16.8%, as compared with the respective control without the lisinopril treatment. Firstly, our findings had proved that the UD polymorphism of ACE gene contrarily responds to the ACE inhibitors in regulating the ACE expression in neurons, which provide a novel insight suggesting genetic testing to tailor the treatment regimens in AD (Alzheimer's disease) patients. 展开更多

BACKGROUND; Polymorphisms of urokinase-type plasminogen activator gene (PLAU) have recently been reported to be associated with sporadic Alzheimer' disease (SAD). However, most studies have focused on the exon region of this gene, and there is no report on the association between promoter polymorphisms of the PLAU and SAD. OBJECTIVE: To determine whether SAD is associated with promoter polymorphisms of PLAU in Northem Han Chinese. DESIGN, TIME AND SETTING: A case-control study was performed at Neurology Laboratory of Xuanwu Hospital of the Capital Medical University from September 2006 to July 2008. PARTICIPANTS: A total of 397 participants living in Beijing were assigned to SAD [n = 196, including 103 males and 93 females, mean age of (64 ± 7) years] and control [n = 201, including 108 males and 93 females, mean age of (68 ± 6) years] groups. The patients were diagnosed and met the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorder Association criteria for possible Alzheimer's disease. Controls received clinical, mental, and neurological examinations to rule out cognitive deficiencies. All controls had Mini-Mental Status Examination scores 〉 27. METHODS: Genotypes of PLAU and apolipoprotein-E were examined in 196 patients with SAD and 201 age- and sex-matched controls from the same community using polymerase chain reaction-restriction fragment length polymorphism method. SPSS 11.5 software was used for data analysis, distribution of allele and genotypic frequency were calculated, and Hardy-Weinberg was also performed in this study. MAIN OUTCOME MEASURES: The main outcome measures were allele and genotype frequency differences in the promoter region of the PLAU gene between SAD and control subjects. RESULTS: In Chinese Han populations, the two polymorphisms in PLAU promoter were -25 C/T (rs2227579) and 43 G/T (rs2227580). Detection of these promoter polymorphisms revealed significant differences in allele and genotype frequency for -25 CfT and 43 G/T when 196 SAD patients were compared with 201 controls (P〈 0.05). Logistic analyses indicated that, compared with C/T and T/T genotypes, the -25 C/C genotype resulted in a 1.5-fold risk for developing SAD (adjusted odds ratio = 1.510, 95% confidence interval: 0.198 2.281, P= 0.010), while the 43G/G genotype resulted in a 1.3-fold risk for SAD (adjusted odds ratio = 1.300, 95% confidence interval: 0.178 2.051, P= 0.030). CONCLUSION: The present study provided evidence that promoter polymorphisms of PLAU are associated with development of SAD in Northern Han Chinese. 展开更多

The promoter region of cauliflower mosaic virus (CaMV) 35s RNA was employed to construct an intermediate expression vector which can be used in Ti plasmid system of Agro-bacterium tumefaciens. The original plasmid, which contains a polylinker between CaMV 35s RNA and its 3' termination signal in pUC18 was modified to have another antibiotic resistance marker (kanamycin resistance gene Kmr) to facilitate the selection of recombinant with Ti plasmid. Octopine synthase (ocs) structural gene was inserted into this vector downstream of CaMV 35s RNA promoter. This chimaeric gene was introduced into integrative Ti plasmid vector pGV3850, and then transformed into Nicotiana tobaccum cells. A binary plasmid vector was also used to introduce the chimaeric gene into tobacco cells. In both cases, the expression of ocs gene was demonstrated. The amount of oc-topine was much more than the nopaline synthesized by no-paline synthase (nos) gene transferred at the same time with Ti plasmid vector. This demonstrated that CaMV 35s RNA promoter is stronger in transcriptional function than the promoter of nos in tobacco cells. 展开更多

Objective To identify the difference and significance of dominant types of hepatitis B virus(HBV) pre-S mutation between liver tumor tissues and paired adjacent non-tumor tissues and to test if the mutations were tumor tissue specific.Methods HBV DNA isolated from 34 paired intratumoral and peritumoral tissues of Hepatocellular Carcinoma(HCC) patients were screened by PCR and direct sequencing. All patients carried HBV with genotype C, except for one B/C heterozygote. The expression, localization and excretion of LHBs mutant carrying pre-S deletions were characterized in vitro. The expression of endoplasmic reticulum(ER) GRP78 m RNA was assayed.Results Four patterns of pre-S mutations were identified: pre-S1 in-frame deletion involving the first start codon; pre-S2 in-frame deletion; pre-S2 start codon mutation with or without in-frame deletion; and S promoter in-frame deletion(ΔSP). The first two types were evenly found in both tumor and non-tumor tissues. They were rarely present as dominant strains. The last two types were frequently found in the dominant strains in tumor tissues. The overall prevalence of HBV carrying ΔSP was 17.64%(6/34) in tumor tissues, but none were dominant in non-tumor tissues. HBV carrying ΔSP was unable to produce S protein in vitro.

Objective To identify the difference and significance of dominant types of hepatitis B virus(HBV) pre-S mutation between liver tumor tissues and paired adjacent non-tumor tissues and to test if the mutations were tumor tissue specific.Methods HBV DNA isolated from 34 paired intratumoral and peritumoral tissues of Hepatocellular Carcinoma(HCC) patients were screened by PCR and direct sequencing. All patients carried HBV with genotype C, except for one B/C heterozygote. The expression, localization and excretion of LHBs mutant carrying pre-S deletions were characterized in vitro. The expression of endoplasmic reticulum(ER) GRP78 m RNA was assayed.Results Four patterns of pre-S mutations were identified: pre-S1 in-frame deletion involving the first start codon; pre-S2 in-frame deletion; pre-S2 start codon mutation with or without in-frame deletion; and S promoter in-frame deletion(ΔSP). The first two types were evenly found in both tumor and non-tumor tissues. They were rarely present as dominant strains. The last two types were frequently found in the dominant strains in tumor tissues. The overall prevalence of HBV carrying ΔSP was 17.64%(6/34) in tumor tissues, but none were dominant in non-tumor tissues. HBV carrying ΔSP was unable to produce S protein in vitro.
