Quantification of cell-associated replication-competent HIV, in blood samples from patients with undetectable plasma viremia, requires specialized culture conditions that include exogenous pan T cell stimulation. Different research groups have used several stimuli for this purpose; however, the relative efficacies of these T cell stimuli to induce productive HIV replication from latently infected cells ex vivo have not been systematically evaluated. To this end, we compared four commonly used T cell stimuli: 1) irradiated allogeneic cells plus phytohaemagglutinin (PHA); 2) PHA alone; 3) phorbol myristate acetate plus Ionomycin; and 4) immobilized αCD3 plus αCD28 antibodies...

BACKGROUND: Although there is evidence that human papillomavirus (HPV) vaccination may protect against oral HPV infection, no current research has demonstrated this in the general population. METHODS: We used repeated cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) between 2009 and 2014. Participants 18-30years who indicated whether they had received the HPV vaccine and provided an adequate oral sample were included (N=3040)...

Accurate estimates of Mycobacterium tuberculosis (M.tb) infection in young children provide a critical indicator of on-going community M.tb transmission. Cross reactions due to infection with environmental mycobacteria and/or Bacille Calmette-Guérin (BCG) vaccination compromise the estimates derived from population-level tuberculin skin test surveys using traditional cut-off methods. Newer statistical approaches are prone to failure of model convergence, especially in settings where the prevalence of M.tb infection is low and environmental sensitisation is high...

Despite the fact that human papillomavirus (HPV) infection and HPV-related cancers are on the rise in men, male HPV vaccine series completion is less than 10% in many areas. This study examined parental knowledge of the HPV vaccine and intent to vaccinate their sons. A cross-sectional study of 341 parents of boys was conducted in school settings in rural southeastern Georgia. Mothers were 2.07 times more likely than fathers to vaccinate their sons. Future research directions should include strategies to increase HPV vaccination in both genders and focus on parents' perceived severity and vulnerability of their sons to HPV infection...

Type I and type III interferons (IFNs) are induced by viral infection. It was concluded that these IFN species are identical in regulation and biological functions. However, these two systems differ in the tissue expression of their receptors and their transcriptional regulation is fundamentally different as well as cellular signaling pathways that drive expression of each IFN. Here, we have investigated the transcriptional profile of endogenous IFNs after stimulation of cells with exogenous IFNs and subsequent infection of A549 cells with A/chicken/Germany/27 [H7N7] influenza virus...

Background. Neutrophils are involved in the pathogenesis of atherosclerosis by neutrophil extracellular trap (NET) formation. We hypothesized that the NET formation of neutrophils might be changed in end-stage renal disease (ESRD) patients, explaining their higher incidence of coronary artery diseases (CAD). Method. A cross-sectional study was performed in 60 maintenance hemodialysis (MHD) patients, 30 age- and sex-matched healthy individuals (HV, negative control), and 30 patients with acute infection (positive control)...

Wide quantitative variation in plant disease resistance across Arabidopsis wild populations has been documented and the underlying mechanisms remain largely unknown. To investigate the genetic and molecular basis of this variation, Arabidopsis recombinant inbred lines (RILs) derived from Aa-0 × Col-0 and Gie-0 × Col-0 crosses were constructed and used for inoculation with Pseudomonas syringae pathovars maculicola ES4326 (ES4326) and tomato DC3000 (DC3000). Bacterial growth assays revealed continuous distribution across the large differences between the most and the least susceptible lines in the RILs...

Cervical cancer is a major public health problem and one of the leading causes of cancer deaths in women. Virtually all cases of cervical cancer, as well as a growing share of anal and head/neck tumors, are associated with human papillomavirus (HPV) infection. Despite the effectiveness, the available prophylactic vaccines do not benefit women with cervical lesions or cancer. Therefore, the search of new immunotherapeutic approaches to treat HPV-induced tumors is still a priority. The present study characterizes a therapeutic antitumor vaccine based on the genetic fusion of the Herpes simplex virus-1 (HSV-1) glycoprotein D (gD) with the E7 oncoprotein from HPV-16 (gDE7)...

Resistance-associated substitutions (RASs) to the new HCV NS5A inhibitor elbasvir may limit its efficacy and lead to virological failure in HCV-GT1a-infected patients. There are no data outside clinical trials evaluating their prevalence and impact in grazoprevir/elbasvir in GT1a-infected patients in Spain. A multicentre cross-sectional study of 632 initial patients was conducted. In 13 of these patients, the sample could not be amplified or a consensus sequence by Sanger sequencing could not be performed. Ultimately, 617 HCV-G1a-infected individuals treated at 84 Spanish hospitals from the 17 autonomous communities plus the 2 autonomous cities of Spain were analysed...

Tissue engineering offers a promising strategy to restore injuries resulting from trauma, infection, tumor resection, or other diseases. In spite of significant progress, the field faces a significant bottleneck; the critical need to understand and exploit the interdependencies of tissue healing, angiogenesis, and inflammation. Inherently, the balance of these interacting processes is affected by a number of injury site conditions that represent a departure from physiological environment, including reduced pH, increased concentration of free radicals, hypoglycemia, and hypoxia...
