The influence of nitrogen deficiency and excess in potato plants on biomass accumulation and distribution

open access: yesActa Agrobotanica, 2013
Nitrogen nutrition index (NNI), harvest index (HI), dry matter accumulated by different organs were estimated several times during the vegetation period of potato plants grown in the both field and pot experiments at the Experimental Station in Jadwisin,

Radioprotection by Acclimatization to Cold [PDF]

open access: yesNature, 1963
THREE parallel series of irradiation have been run simultaneously to compare, in rats, the effects of acute and chronic whole-body irradiation by cobalt-60 γ-rays and to establish the radio-modifying effects of cold acclimatization in the latter condition1.

Erythrocytes retain hypoxic adenosine response for faster acclimatization upon re-ascent

open access: yesNature Communications, 2017
Faster acclimatization to high altitude upon re-ascent is seen in humans; however, the molecular basis for this enhanced adaptive response is unknown. We report that in healthy lowlanders, plasma adenosine levels are rapidly induced by initial ascent to ...

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Effect of location on starch content and tuber texture characteristics in potato breeding lines and cultivars

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
The texture of boiled potato tubers is one of the most important quality traits. The variation of tuber texture is usually examined in relationship with dry matter or starch content.

Quantification of DNA of Fusarium culmorum and Trichothecene Genotypes 3ADON and NIV in the Grain of Winter Wheat

open access: yesPathogens, 2022
Fusarium head blight (FHB) is a wheat disease caused by fungi of the genus Fusarium. The aim of the study was to find relationships between the weather conditions in the experimental years and the locations and the amount of F.

Altitude Acclimatization Alleviates the Hypoxia-Induced Suppression of Exogenous Glucose Oxidation During Steady-State Aerobic Exercise

open access: yesFrontiers in Physiology, 2018
This study investigated how high-altitude (HA, 4300 m) acclimatization affected exogenous glucose oxidation during aerobic exercise. Sea-level (SL) residents (n = 14 men) performed 80-min, metabolically matched exercise (V˙O2 ∼ 1.7 L/min) at SL and at HA

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

open access: yesAdvanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...
