Adsorção de fósforo em dez solos do Estado de Pernambuco e suas relações com parâmetros físicos e químicos = Phosphorus adsorption in ten soils from Pernambuco State and its relations with physical and chemical parameters

Acta Scientiarum. Agronomy, 2011
Um experimento foi conduzido para estudar a adsorção de fósforo (P) emamostras de dez solos do Estado de Pernambuco, Nordeste do Brasil. As relações entre atributos físicos e químicos do solo e as isotermas de adsorção de P foram também avaliadas.

An introduction to the study of phosphorus dynamics in Rondevlei

, 1991
Bibliography: leaves 120-134.Phosphorus is one of the most important nutrients in aquatic environments because of the role that it plays in eutrophication. Increased amounts of phosphorus stimulate excessive growth of nuisance plants, which have negative

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

A Biomimetic Dual‐Targeting Nano‐APA‐Editor Reprograms the 3'UTR Landscape for Tongue Squamous Cell Carcinoma Therapy

Advanced Science, EarlyView.
This study unveils a pathogenic axis in oral cancer where NUDT21 suppresses a tumor suppressor network, prominently PTEN, via 3'UTR lengthening. To exploit this transcriptomic vulnerability, we developed a biomimetic Nano‐APA‐editor. By delivering CRISPR/Cas9, we reprogrammed the global 3'UTR landscape, restoring multi‐target tumor suppression and ...

Yield and nitrogen use efficiency in optimized oat-common vetch mixtures on the Qinghai–Tibet plateau

Frontiers in Plant Science
This study investigated the systemic effects of various nitrogen (N) regimes and phosphorus (P) additions on growth traits, N accumulation, and N fixation efficiency in mixed sowing systems of oat (Avena sativa L.) and common vetch (Vicia sativa L.) on ...

Targeting the HSPA8‐CMA‐ATP6V1A Axis Triggers Lysosomal Hyperacidification and Catastrophic Vacuolation in Prostate Cancer

Advanced Science, EarlyView.
Our experimental evidence supports a model in which ALO targets the HSPA8‐CMA‐ATP6V1A axis to induce lysosomal hyperacidification and initiate osmotic and lipidomic stress. These changes are associated with LMP and loss of lysosomal integrity in prostate cancer cells.

Influence of N, P, and Fe availability on Braarudosphaera bigelowii, Trichodesmium, Crocosphaera, and noncyanobacterial diazotrophs: a review

Frontiers in Marine Science
Marine biological nitrogen fixation (BNF) is crucial for introducing “new nitrogen” into the oceans. Over the past 30 years, numerous laboratory and on-board culture experiments have been conducted studying the effects of nutrients such as total ...

Integrative Omics Analysis Reveals the Regulation of Hypoxia Tolerance in Large Yellow Croaker (Larimichthys crocea) via the Lipoic Acid Synthase (lias) Gene

Advanced Science, EarlyView.
Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the
