Resumen

Most illegal Ponzi schemes are ultimately out of control and lead to systemic financial risk. Risk education and precaution are similar to mass random immunization of epidemic spreading. In this study, the effect of random immunization strategy is evaluated based on the potential-investor–divestor (PID) spreading model in both homo- and inhomogeneous social networks. Fund flux function and system balance function are formulated. The zero point of system balance is used as the collapse point. The peak value of balance, the total number of investors involved and the total amount of principal inv

Resumen

The "One Health" strategy envisions the control of all processes in the food production chain “from farm to fork.” The detection of biotoxigens, including enterotoxigenic Escherichia coli, can be carried out by various methods. However, none of them can be classified as rapid methods. The fluorescent antibody technique (FAT), which combines the objectivity of microscopic methods with the high specificity of immunological reactions, may be applied in such a role. Analysis of FAO reports shows that monitoring for the presence of enteropathogenic E. coli is a vital part of the "One Health" strate

Resumen

Abstract Vaccination needs to prepare the immune system to rapidly secrete specific antibodies upon a future encounter with the pathogen. Assessments of this feature are often challenging to perform, as measurements using antibody titers represent only a poorly resolved average of the rapidly evolving repertoire. We recently published and described a novel, droplet-based microfluidic technology that allows the quantitative characterization of humoral immune responses with single-cell and -antibody resolution. The employed snapshot analysis in this system enables studying even rapidly evolving

Resumen

Improving specific prevention of tuberculosis continues to be a top priority in phthisiology. “Prime-boost” vaccination schemes aim to maintain adequate levels of specific immunity while forming long-term protection. They are based on sequential use of BCG vaccine and new vaccine candidates expressing protective mycobacterial proteins. The development of new tuberculosis prevention approaches requires an understanding of how the anti-tuberculosis immune response forms and which mechanisms provide TB protection. Since tuberculosis is an airborne infection, vaccine effectiveness largely depends

Trueperella pyogenes (T. pyogenes) is a crucial opportunistic pathogen normally causing mastitis, abscesses and pneumonia in economically important ruminants.

Pyolysin (PLO) is the most predominant virulence factor highly expressed in T. pyogenes and is an excellent target for the development of novel vaccines against T. pyogenes. In this study, we designed a heterologous prime-boost vaccination scheme combining a DNA vaccine pVAX1-PLO and a subunit vaccine His-PLO to maximize h

Resumen

Theory is developed for an epidemic model of a seasonally-spreading vector-borne disease using a hybrid system framework. Applicable to diseases spread by mosquitoes (e.g., chikungunya and Zika virus via Aedes albopictus), seasonal variations in transmission are modeled using switching parameters to represent term-time forcing. The vector agent is assumed to exhibit a period of incubation upon infection, modeled using a distribution. Three hybrid control strategies are analyzed in detail: switching cohort immunization, pulse vaccination at pre-specified times, and state-dependent pulse vaccina

We discuss the epidemic network model with infectious force in latent and infected period.

The effects of various immunization schemes are studied. Finally, the final sizes relation is derived for the network epidemic model. The derivation depends on an explicit formula for the basic reproduction number of network of disease transmission models.

Resumen

In December 2019, a case of atypical pneumonia was reported in Wuhan, China. It was named COVID-19 and caused by SARS-CoV-2. In a few months, scientific groups around the world developed vaccines to reduce the disease’s severity. The objective was to evaluate the humoral and cellular immune response post immunization with three different vaccination schedules administered in Chile until January 2022. Sixty volunteers were recruited with a three-dose schedule, who had no history of infection nor close contact with a positive patient. IgG against the spike antigenic domain was detected, and the

Resumen

SARS-CoV-2 variants of concern (VOCs) or of interest (VOIs) causing vaccine breakthrough infections pose an increased risk to worldwide public health. An observational case-control study was performed of SARS-CoV-2 vaccine breakthrough infections in hospitalized or ambulatory patients in Monterrey, Mexico, from April through August 2021. Vaccination breakthrough was defined as a SARS-CoV-2 infection that occurred any time after 7 days of inoculation with partial (e.g., first dose of two-dose vaccines) or complete immunization (e.g., second dose of two-dose vaccines or single-dose vaccine, acco

Based on the study of materials from state reports «On the state of sanitary and epidemiological welfare of the population.» It was found that there was no constant circulation of the measles virus in the Ryazan region in 2000–2023. There have been periodic increases in morbidity due to the importation of the pathogen with its subsequent spread among unvaccinated individuals. The main reasons for the deterioration of the epidemic situation were errors in the immuno

Resumen

Gold nanoparticles as part of vaccines greatly increase antigen stability, antigen accumulation in the lymph nodes, and antigen uptake by antigen-presenting cells. The use of such particles as part of anticancer vaccines based on heat shock proteins to increase vaccine effectiveness is timely. We prepared and characterized nanoconjugates based on 15-nm gold nanoparticles and thermostable tumor antigens isolated from MH22a murine hepatoma cells. The whole-cell lysate of MH22a cells contained the main heat shock proteins. BALB/c mice were injected with the conjugates and then received transplant

Resumen

ABSTRACTIn a follow-up to the modest efficacy observed in the RV144 trial, researchers in the HIV vaccine field seek to substantiate and extend the results by evaluating other poxvirus vectors and combinations with DNA and protein vaccines. Earlier clinical trials (EuroVacc trials 01 to 03) evaluated the immunogenicity of HIV-1 clade C GagPolNef and gp120 antigens delivered via the poxviral vector NYVAC. These showed that a vaccination regimen including DNA-C priming prior to a NYVAC-C boost considerably enhanced vaccine-elicited immune responses compared to those with NYVAC-C alone. Moreover,

Resumen

Background: Vaccines have had a great impact on disease prevention and reducing mortality. Very rarely, vaccines also can result in serious adverse effects. In consideration of this fact, vaccine injury compensation programs have been implemented in many countries to compensate a vaccinee for associated adverse effects. The existing vaccine injury compensation system addresses routine immunization schemes. However, there are rising concerns about the compensation for adverse effects caused by new vaccines such as those developed for coronavirus disease 2019 (COVID-19). This review focuses on v

This may lead to miscarriage, stillbirth, delayed fetal growth and maturation (intrauterine growth retardation), or pre-term delivery. This study aimed to evaluate the prevalence of ToRCH infections in pregnant women in Port Harcourt. Sera from 84 pregnant women between the ages of 16 and 45 were analysed for detectable ToRCH IgM antibodies using the Dia-Pro ToRCH IgM kit. The results from the study showed an IgM seroprevalence rate of 82.1%, with the highest rate of seropositivity

China's health reforms of the 1980s led to privatization of rural health care with adverse impact on farmers. A decade later a new rural co-operative medical scheme (RCMS), was piloted throughout many provinces to promote better equity. Although many schemes later collapsed owing to inadequate funding, some continue to the present. This article compares such a scheme with the out-of-pocket system in Henan province. We study the township hospitals, focusing on cost of services, utilization rates and impact of RCMS on hospitals' financial sustainability. Our results derive from monthly hospital
