Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

Advanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed

Subtropical grass pollen allergens are important for allergic respiratory diseases in subtropical regions [PDF]

Clinical and Translational Allergy, 2012
AbstractBackgroundGrass pollen allergens are a major cause of allergic respiratory disease but traditionally prescribing practice for grass pollen allergen‐specific immunotherapy has favoured pollen extracts of temperate grasses. Here we aim to compare allergy to subtropical and temperate grass pollens in patients with allergic rhinitis from a ...

Variability in the subtropical-tropical cells and its effect on near-surface temperature of the equatorial Pacific: a model study [PDF]

, 2007
A set of experiments utilizing different implementations of the global ORCA-LIM model with horizontal resolutions of 2°, 0.5° and 0.25° is used to investigate tropical and extra-tropical influences on equatorial Pacific SST variability at interannual to ...

Using Sensory Analysis and Stated Preference Valuation to Assess the Willingness to Pay for Fresh Tomato Attributes

Agribusiness, EarlyView.
ABSTRACT This study combines sensory analysis and stated preference valuation techniques to assess the monetary value of organoleptic attributes of new tomato varieties. The tomatoes evaluated included two new varieties adapted to South Texas growing conditions, a commercial check, and tomatoes imported from Mexico.

Transport timescales and tracer properties in the extratropical UTLS [PDF]

, 2010
A comprehensive evaluation of seasonal backward trajectories initialized in the Northern Hemisphere lowermost stratosphere (LMS) has been performed to investigate the origin of air parcels and the main mechanisms determining characteristic structures in ...

Machine Learning‐Assisted Infectious Disease Detection in Low‐Income Areas: Toward Rapid Triage of Dengue and Zika Virus Using Open‐Source Hardware

Advanced Intelligent Discovery, EarlyView.
This study introduces an affordable machine learning platform for simultaneous dengue and zika detection using fluorine‐doped tin oxide thin films modified with gold nanoparticles and DNA aptamers. Designed for low‐cost, hardware‐limited devices (< $25), the model achieves 95.3% accuracy and uses only 9.4 kB of RAM, demonstrating viability for resource‐

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

American Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...
