A Simple and High-Throughput ELISA-Based Neutralization Assay for the Determination of Anti-Flavivirus Neutralizing Antibodies

open access: yesVaccines, 2020
Mosquito-borne flavivirus infections, including dengue virus and Zika virus, are major public health threats globally. While the plaque reduction neutralization test (PRNT) is considered the gold standard for determining neutralizing antibody levels to ...

Phosphorus Deficiency Affects Memory‐Mediated Recovery From Recurrent Water Stress in Drought‐Sensitive Soybean

open access: yesPhysiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Phosphorus (P) deficiency and water deficit are major constraints to soybean yield worldwide. While their individual impacts are well established, little is known about how P deficiency modulates soybean recovery from recurrent water stress.

Comparative inflammatory and regulatory cytokine signatures triggered by the YF-17DD and YF-17D-213/77 substrains upon the in vitro recall of whole blood leukocytes from (A) seroconverter (PV-PRNT+) and nonseroconverter primary vaccinees (PV-PRNT) as well as (B) seroconverter revaccinees (RV-PRNT+) with specific YF-Ag.

open access: yes, 2013
The ascendant frequency of volunteers with high inflammatory and regulatory cytokine indexes was assembled for each experimental arm and demonstrated by bar graphs.

Multicentric evaluation of sensitivity of eight commercial anti-SARS-CoV-2 antibody assays and their correlation to virus neutralization titers in seropositive subjects

open access: yesScientific Reports
Diagnosis of SARS-CoV-2 virus is mainly based on direct detection. Determination of specific antibodies has been used mostly for epidemiological reasons.

Attenuated Infectious Bronchitis Virus (IBV) Vaccination Induces Protective Humoral and Cellular Immunity Against SARS‐CoV‐2 in Mammals

open access: yesJournal of Immunology Research, Volume 2026, Issue 1, 2026.
Occupational exposure to infectious bronchitis virus (IBV) has been associated with cross‐reactivity to other coronaviruses such as SARS‐CoV‐2. In this study, we investigated the immune response of IBV using reconstituted samples of the commercial H120 Mass‐I vaccine (Zoetis) against SARS‐CoV‐2 infection.

Quality evaluation of agricultural limestones by PRNT

open access: yes, 1988
Agricultural limestones of various PRNT (Relative Power of Total Neutralization) values, calculated considering the relative efficiency of their granulometric fractions, were used in a comparative study. A number of 22 limestone samples were collected ; 12 from different mills from the municipalities of Rio Claro, Piracicaba and Tietê and 10 selected ...

Cholesterol in mRNA‐Lipid Nanoparticles can be Replaced with the Synthetic Mycobacterial Monomycoloyl Glycerol Analogue MMG‐1

open access: yesAdvanced Functional Materials, Volume 35, Issue 51, December 16, 2025.
This study demonstrates that cholesterol in messenger RNA‐lipid nanoparticles (mRNA‐LNPs) can be completely replaced with an immunopotentiating lipid, i.e., a synthetic analogue of the C‐type lectin receptor agonist monomycoloyl glycerol (MMG‐1), without compromising physicochemical properties, in vivo transfection efficiency, and immunogenicity of the

Impaired Cellular Immunity and Cross‐Reactive Humoral Responses to Mpox Virus in HIV‐Infected Individuals Vaccinated with Vaccinia Virus Tiantan Strain

open access: yesMedComm, Volume 6, Issue 12, December 2025.
This study examines MPXV immunity in PLWH, focusing on smallpox vaccine‐induced responses. PLWH with CD4⁺ T‐cell counts <500 cells/mm3 showed reduced VTT‐IgG, MPXV‐IgG, and NAbs, while CD4⁺ T‐cell responses were impaired at counts <350 cells/mm3. CD8⁺ T‐cell responses remained stable.

Vaccinia-specific PRNT GMTs by Week (IAS, N = 119).

open access: yes, 2016
Administrations at week 0 (Group MM: first MVA vaccination; Group PM: Placebo) and at week 4 (Group MM: second MVA vaccination; Group PM: first MVA vaccination). No samples were taken between week 8 and 32, therefore the graph was cut.

Determination of fracture mechanics parameters on pipe ring notch tensile (prnt) specimens [PDF]

open access: yes
Determining the parameters of fracture mechanics is a key segment in assessment and enhancement of the safety and longevity of materials and structures, especially when they are exposed to extreme load conditions in the presence of damage. In this work, one group of such structures is considered - thin-walled pipelines, which are used in practically ...
