Association of TLR3 single nucleotide polymorphisms with susceptibility to HTLV-1 infection in Iranian asymptomatic blood donors

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2020
INTRODUCTION: The human T-lymphotropic virus type 1 (HTLV-1) has a single-stranded RNA genome and expresses specific proteins that have oncogenic potential. Approximately 15 to 20 million people worldwide have been infected by this virus.

Human leukocyte antigen class I, class II, and tumor necrosis factor-alpha polymorphisms in a healthy elder Mexican Mestizo population [PDF]

open access: yes, 2005
BACKGROUND: There is strong evidence that an individual's genetic background is an important predisposing factor to longevity. In the present study we analysed the frequency of HLA class I, class II, as well as the TNF-α -308 polymorphism that may be ...

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Simple and Environmentally Friendly Solution Synthesis of CsPbI3 Nanoribbons: Investigating the Reversible δ‐ to γ‐Phase Transition

open access: yesAdvanced Photonics Research, EarlyView.
Cesium lead iodide (CsPbI3) nanoribbons obtained through mild condition synthesis are herein reported without surfactant species and toxic solvent starting from β‐diketonate complexes of Cs and Pb. The morphological and structural features, together with the thermal stability and phase transitions from the yellow δ to the black α and γ‐CsPbI3 phases ...

Tomato: a crop species amenable to improvement by cellular and molecular methods [PDF]

open access: yes, 1989
Tomato is a crop plant with a relatively small DNA content per haploid genome and a well developed genetics. Plant regeneration from explants and protoplasts is feasable which led to the development of efficient transformation procedures.

Modification of the terminal restriction fragment length polymorphism analysisfor assessment of a specific taxonomic group within a soil microbial community

open access: yesPlant, Soil and Environment, 2009
A double color terminal restriction fragment length polymorphism analysis was applied for the diversity assessment of a complex bacterial community in a deciduous forest soil. Application of the second label was used to project a specific taxonomic group
