Field Strength‐Dependent White Matter R1 and R2 Anisotropy of Phase‐Cycled Balanced Steady‐State Free Precession Relaxometry

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2873-2891, May 2026.
ABSTRACT Purpose To investigate how the relaxation rates (R1, R2) and asymmetry indices (AI), derived from phase‐cycled balanced steady‐state free precession (pc‐bSSFP) data, depend on the orientation of white matter (WM) fiber tracts at different field strengths.

Barrett's Esophageal Adenocarcinoma with Neuroendocrine Cell Carcinoma Treated by Endoscopic Submucosal Dissection: A Case Report and Literature Review

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Barrett's esophageal adenocarcinoma (BEA) with neuroendocrine cell carcinoma (NEC) is a rare disease with a poor prognosis. We report a case of BEA with NEC treated by endoscopic submucosal dissection (ESD) with en bloc resection and long‐term survival was achieved without additional treatment.

Quality of Forage Cactus Silage with the Addition of Hay from Forages Adapted to the Semiarid Region

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This study investigated the effects of including hays from different forages adapted to the semiarid region on the forage cactus (Opuntia fícus‐indica (L.) Mill) silage quality. A completely randomized design, with five treatments was used: pure forage cactus and forage cactus associated with 30% hay from gliricidia (Gliricidia sepium), pornunça ...

Effect of Different Irrigation Programs on Structural Characteristics, Productivity and Water Use Efficiency of Opuntia and Nopalea Forage Cactus Clones

Grasses
The objective of this study was to evaluate the structural characteristics, yield and water use efficiency of forage cactus under daytime and nighttime irrigation in a Brazilian semiarid region. The experiment followed a completely randomized design in a

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

Journal of Applied Entomology, Volume 150, Issue 3, Page 321-332, April 2026.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

Journal of Applied Entomology, Volume 150, Issue 3, Page 351-363, April 2026.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Longevity in plants impacts phylogenetic and population dynamics

New Phytologist, Volume 250, Issue 1, Page 661-671, April 2026.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.

Convective Biases in the US DOE Global Storm‐Resolving Model: Insights From Regionally Refined Simulations During the CACTI Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Accurately simulating convective processes in complex terrain remains a critical challenge for global storm‐resolving models (GSRMs). This study systematically evaluates moist convective biases in the Regionally Refined Mesh configuration of the U.S.

Comparative analysis of pomological and phytochemical characteristics in white‐ and red‐fleshed pitaya (Hylocereus spp.), with molecular docking insights into key bioactive compounds

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2200-2210, 15 March 2026.
Abstract BACKGROUND Cacti, including pitaya (Hylocereus spp.), are rich in antioxidants that will undoubtedly gain importance under ongoing climate change as water resources decline. Yet the molecular basis linking composition to antioxidant function remains incompletely defined. We compared white‐fleshed H. undatus and red‐fleshed H. polyrhizus across
