HUMIC ACID ON GERMINATION AND VIGOR OF CORN SEEDS

open access: yesRevista Caatinga, 2016
The development of technologies to increase stand establishment efficiency and seed vigor, as well as to maximize profits, is of fundamental importance for the sustainability of agriculture. Products based on humic substances, such as humic acids, have been recently used in Brazilian agriculture to produce seedlings with high vigor, which positively ...

Low‐Temperature Processed Optoelectronic Synapses With Enhanced Responsivity for Edge‐Oriented In‐Sensor Reservoir Computing

open access: yesAdvanced Materials Technologies, EarlyView.
Image pixels are converted into optical pulse sequences to stimulate the optoelectronic synaptic device, generating dynamic responses that form high‐dimensional features. These features improve classification efficiency and demonstrate strong potential for neuromorphic edge computing systems.

Incidence and post-pollination mechanisms of nonrandom mating in Arabidopsis thaliana [PDF]

open access: yes, 2009
Compatible pollinations from many differenttaxa display nonrandom mating. Here we describe a systemfor examining questions of nonrandom mating in Arabidopsisthaliana.

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

open access: yesAdvanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

open access: yesAdvanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Evaluation of Pre-sowing Seed Treatments Using Organic Solutions on Seed Germination and Seedling Vigor Parameters of Okra (Abelmoschus esculentus Var. Nancy)

open access: yesTurkish Journal of Agriculture: Food Science and Technology
The germination of okra is poor due to its tough seed coats, undeveloped embryos, and adverse conditions which seem problematic in its cultivation. Seed priming is one of the best ways to induce seed germination and crop vigor in okra.

Magnetic field effects on seed germination and activities of some enzymes in cumin [PDF]

open access: yes, 2013
Failure of germination among Apiaceae family seeds, e. g. cumin (Cuminum cyminum), has been reported by many investigators. Until now few works have been done on seed germination and seedling growth of cumin.

Mechanostimulatory Cues Determine Intestinal Fibroblast Fate and Profibrotic Remodeling in a Physiodynamic Human Gut‐on‐a‐Chip

open access: yesAdvanced Science, EarlyView.
A healthy gut barrier shields underlying fibroblasts from luminal shear forces, illustrating that “good fences make good neighbors.” Barrier damage exposes fibroblasts to shear stress, inducing cell death and the emergence of stress‐adapted, profibrotic fibroblasts. Sustained shear exposure promotes the formation of stiff aggregates of mechanoadapative
