The surface details of resin embedded viruses can be greatly enhanced by the use of uranyl acetate block staining. The virions are embedded in agar immediately after fixation and block stained with 3% uranyl acetate in methanol during dehydration. This technique allows those particles outside their
In this study, Ti-mineral superfine powders (Ti-MSP) encapsulated in urea-formaldehyde resin microcapsules (Ti-MSP@UF-MC) were successfully prepared via a one-step microemulsion method for the first time. Because of the strong confinement effects, the Ti-MSP@UF-MC possessed perfect microwave heating
Blood cultures are routinely performed as part of the evaluation of fever in the perioperative period. Results of 364 blood culture vials representing 108 consecutive febrile events (temperature greater than or equal to 101.5 degrees F) in 72 patients on adult surgical services without evidence of
African swine fever is an acute, febrile and highly virulent porcine disease causing serious economic losses worldwide. The pK205R protein of the African swine fever virus (ASFV) is largely expressed in the early stages of infection, which has given the K205R gene extensive attention. In this study,
Hantavirus nucleocapsid protein has recently been identified as a major antigen inducing an early and long-lasting humoral immune response in patients with hemorrhagic fever with renal syndrome. A mu-capture enzyme-linked immunosorbent assay utilizing recombinant nucleocapsid proteins of Hantavirus
Honey bees use several strategies to protect themselves and the colony from parasites and pathogens. In addition to individual immunity, social immunity involves the cumulative effort of some individuals to limit the spread of parasites and pathogens to uninfected nestmates. Examples of social
BACKGROUND
Magnetic hyperthermia is currently a clinical therapy approved in the European Union for treatment of tumor cells, and uses magnetic nanoparticles (MNPs) under time-varying magnetic fields (TVMFs). The same basic principle seems promising against trypanosomatids causing Chagas disease and
African swine fever virus (ASFV) is a large complex icosahedral double-stranded DNA virus that replicates in the cytoplasm of susceptible cells. Assembly of new virus particles occurs within the perinuclear viroplasm bodies known as virus factories. Two types of virus particle are routinely
Seven young men developed acute pulmonary hemorrhage and edema from the inhalation of powder or fumes of a bisphenol epoxy resin containing tri-mellitic anhydride (TMA) while working in a steel pipe-coating plant. The illness was characterized by cough, hemoptysis, dyspnea, fever, weakness and
Scanning and transmission electron microscopy (S.E.M. and T.E.M.) and resin histology have been used to investigate the effects on mouse small intestinal villi of heating at 43 degrees C for 20 minutes and of irradiation with 10 Gy X-rays. Damage after irradiation included conical villi and giant
OBJECTIVE
The intoxications caused by 2,4-dinitrophenol (2,4-DNP), even death, have been frequently reported in recent years. This study aims to investigate the dynamic changes of plasma toxin concentration and explore the clinical value of resin hemoperfusion (HP) in the treatment of patients with
1. A 38-year-old previously healthy worker accidentally spilled phenol-formaldehyde resin over a large area of his skin. 2. Several days later he was hospitalized with extensive necrotic skin lesions, fever, hypertension, adult respiratory distress syndrome (ARDS), proteinuria and renal functional
The effect on the vasculature of mouse intestine was observed following: (a) irradiation alone; and (b) irradiation followed at intervals of 0-60 days by hyperthermia. Specimens of intestine were removed after sacrifice and the vasculature revealed by benzidine staining before clearing in resin. The
OBJECTIVE
Focal hyperthermia by laser or radiofrequency is currently the preferred method for local ablation of liver tumors. The underlying mechanism of action of focal hyperthermia, in particular the relationship between the microvascular and tissue effect is uncertain and was investigated in a
The manufacture of solid components with high permittivities epsilon r of 1-100 and differing conductivities sigma of 0-1.0 S/m has practical significance for fabricating applicators and phantoms in radiofrequency hyperthermia. For this purpose, various plastics (resins, polyurethane and silicone)
