Investigating Prime-Pull Vaccination through a Combination of Parenteral Vaccination and Intranasal Boosting

open access: yesVaccines, 2019
Formulation of inhalable delivery systems containing tuberculosis (TB) antigens to target the site of infection (lungs) have been considered for the development of subunit vaccines. Inert delivery systems such as poly (lactic-co-glycolic acid) (PLGA) are

Pleistocene Climate Changes and Lineage Diversification of Sphenarium Grasshoppers (Orthoptera: Pyrgomorphidae)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...

The u'g'r'i'z' Standard Star Network

open access: yes, 2002
We present the 158 standard stars that define the u'g'r'i'z' photometric system. These stars form the basis for the photometric calibration of the Sloan Digital Sky Survey (SDSS).

Unstained Blood Smear Analysis: A Review of Rule‐Based, Machine Learning, and Deep Learning Techniques

open access: yesJournal of Biophotonics, Volume 18, Issue 10, October 2025.
Bright‐field images of unstained smears. (1) Sparse erythrocytes allow straightforward intensity‐ or phase‐based segmentation. (2) Overlapping cells blur boundaries, causing over‐ or under‐segmentation and lowering rule‐based accuracy, thus motivating overlap‐aware algorithms for reliable downstream feature extraction and classification. ABSTRACT Blood

Complex population genetic structure of the bark beetle predator Thanasimus formicarius (L.) (Coleoptera: Cleridae) across its European range

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 3, Page 437-451, August 2025.
Abstract Thanasimus formicarius (L.) (Coleoptera: Cleridae) is an important bark beetle predator and can reduce bark beetle population densities of some of the most severe forest pests in Europe. We analysed the population genetics and phylogeography of T.

Th1 immune responses can be modulated by varying dimethyldioctadecylammonium and distearoyl-sn-glycero-3-phosphocholine content in liposomal adjuvants [PDF]

open access: yes, 2014
OBJECTIVES: Cationic liposomes of dimethyldioctadecylammonium bromide (DDA) combined with trehalose 6,6'-dibehenate (TDB) elicit strong cell-mediated and antibody immune responses; DDA facilitates antigen adsorption and presentation while TDB potentiates

Replacement of large subunit N terminus enabled biogenesis of different plant Rubiscos in E. coli

open access: yesPlant Biotechnology Journal, Volume 23, Issue 8, Page 3382-3391, August 2025.
Summary The efforts of engineering plant ribulose‐1,5‐bisphosphate carboxylase/oxygenase (Rubisco) with the goal of improving plant photosynthetic efficiency and crop yield have existed for long. However, the directed evolution of plant Rubisco has not been widely explored because its biogenesis in a heterologous host such as Escherichia coli remains ...

Modulation of primary immune response by different vaccine adjuvants

open access: yesFrontiers in Immunology, 2016
Adjuvants contribute to enhancing and shaping the vaccine immune response through different modes of action. Since the primary immune response can influence the overall quality of the response generated, here we investigate early biomarkers of ...
