In 1994-1996, 185 strains of dengue (DEN) virus types 1, 2, and 4 were recovered from febrile United States other Nations military personnel in Haiti. We wondered whether risk factors for hemorrhagic fever (DHF) existed and, if so, DHF cases occurring among Haitian children. Dengue transmission rates studied 210 school children (6-13 years old) resident Carrefour Borough, Port-au-Prince, When sera tested plaque-reduction neutralizing antibodies to DEN 1-4 viruses, nearly 85% had two or more...
Rubber diaphragms are widely used in petroleum, chemical, electric power, metallurgy and other industries, but faults occur frequently. Therefore, it is important to analyze the failure of rubber diaphragm for judging nature finding out cause failure, putting forward improvement measures reduce losses, improving equipment utilization production efficiency. This study summarized common cases use, analyzed listed typical damage characteristics fracture morphology. Through case studies,...
Dengue is a vector-borne disease causing high morbidity and mortality in tropical subtropical countries. Urbanization, globalization, lack of effective mosquito control have lead to dramatically increased frequency magnitude dengue epidemic the past 40 years. The virus vectors keep expanding geographically regions world. Using hot spot analysis spatial-temporal clustering method, we investigated distribution Sri Lanka from 2012 2016 identify clusters elucidate association climatic factors...
In order to end the AIDS epidemic by 2030 that was put forward Joint United Nations Programme on HIV/AIDS in 2014, China needs take more effective measures achieve three 90% goals (90-90-90). We establish a compartmental model study dynamics of HIV transmission with control strategies. The analytical results show existence and stability disease-free equilibrium endemic equilibrium. An optimal is constructed evaluate impacts measures. simulation strategy proposed this work can eradicate 2030....
Dengue is a vector-borne disease mainly affecting tropical and subtropical regions. The transmission of dengue virus affected by many stochastic factors. Hence, we incorporated perturbations into the framework deterministic compartmental model. For this differential equation model, introduced an approximate analogue basic reproduction number to explore existence almost sure exponential stability free equilibrium. We proved uniqueness positive solution for derived conditions using suitable...
Tuberculosis was ranked No. 3 among 29 types of infectious diseases in January 2022 Jiangsu Province, the southeast China, and it has strong seasonality whose incidence rate been high springs low winters. This comprehensive study extends spreading dynamics to control strategies TB Province with time‐varying transmission rate, which is first one this type. The periodic incorporated classic SEIR model susceptible, latent, infectious, recovered compartments. analysis shows that when basic...
Hand, foot, and mouth disease (HFMD) is widely spread in China Mainland, seriously threatening the health of infants young children. We develop a meta‐population model that includes both local ecdemic populations to study impacts fomites immigration on transmission HFMD Shanghai. The direct between susceptible infected individuals (asymptomatic or symptomatic) indirect via fomites. forward bifurcation shows if basic reproduction number less than unity, epidemic will die out; otherwise,...
RNA-dependent RNA polymerase activity was detected in both virion and nucleocapsid preparations of wheat rosette stunt virus, a plant rhabdovirus. The presence nonionic detergent such as Nonidet P40 essential for reaction mixtures containing virions. product proved to be single-stranded RNA. By two-step controlled dissociation the nucleocapsids, four subviral fractions (L protein, NS-N-RNA complex, NS N-RNA complex) were prepared. None these showed when assayed individually. In experiments...
Abstract Background This study aimed to introduce a novel method for ureteroileal anastomosis, explore its clinical effectiveness, observe the incidence of postoperative anastomotic stricture, and compare complications with those other types anastomosis reported in literature. Methods Both ureters were first anastomosed at their distal ends then inserted into proximal end ileal loop. A follow-up analysis was performed evaluate major complication indicators, including leak,...
