nutrientuptake, etc ; brain; endocytosis; lysosomes; neurons; neuroplasticity; neurotoxicity; plasma membrane; Show all 8 Subjects
Abstract:
... Endocytosis is an essential cellular process required for multiple physiological functions, including communication with the extracellular environment, nutrient uptake, and signaling by the cell surface receptors. In a broad sense, endocytosis is accomplished through either constitutive or ligand‐induced invagination of the plasma membrane, which results in the formation of the plasma membrane‐ret ...

Abstract:
... Patients with ultrashort gut have inadequate nutrient absorption. Parenteral nutrition (PN) is required to meet nutrition requirements caused by chronic intestinal failure (IF). We present a case of cachexia and IF caused by ultrashort gut following an extensive small‐bowel resection caused by volvulus that was complicated by small‐bowel ischemia. Targeting energy prescriptions to optimize PN usin ...
nutrientuptake, etc ; RNA; Salmonella enterica; membrane permeability; peptide transporters; porins; porosity; Show all 7 Subjects
Abstract:
... The envelope of Gram-negative bacteria is a vital barrier that must balance protection and nutrient uptake. Small RNAs are crucial regulators of the envelope composition and function. Here, using RIL-seq to capture the Hfq-mediated RNA-RNA interactome in Salmonella enterica, we discover envelope-related riboregulators, including OppX. We show that OppX acts as an RNA sponge of MicF sRNA, a prototy ...

Abstract:
... In the early growth stage, nutrient uptake by rice roots is weak. However, rice tillering at this stage would require high N input. Thus, it is vital to clarify the mechanism involved in tillering capacity with low N inputs. In this report, two widely-planted japonica cultivars (cvs Yangyujing 2 and Nanjing 45) were selected mainly because, unlike cv. Nanjing 45, cv. Yangyujing 2 shows low-N-induc ...

Abstract:
... This study investigated the nutrient removal efficiency of a constructed wetland (CW) piloted to treat urban runoff before entering an estuary. Physico-chemical, dissolved inorganic nutrient (DIN and DIP), and stormwater inflow volume data were measured. The CW removal efficiency of DIN was negligible (5% uptake), while it acted as a consistent source of DIP (68% efflux) to the receiving estuarine ...

Abstract:
... High bicarbonate (HCO₃ ⁻) content and associated high pH of irrigation water are detrimental to plant nutrient absorption. This experiment was arranged as a factorial in the framework of a completely randomized design with two factors, rootstock (ungrafted cucumber, Cucurbita moschata, and Cucurbita maxima) and bicarbonate (10 mM NaHCO₃ or AS and 10 mM NaCl or SS). Regardless of rootstock, bicarbo ...

Abstract:
... In many lentic ecosystems, hydroperiod, or the duration of inundation, controls animal community composition and biomass. Although hydroperiod-imposed differences in wetland animal communities could cause differences in animal-driven nutrient supply, hydroperiod has not been considered as a template for investigating patterns of animal-driven nutrient cycling. Here, we use nutrient excretion rates ...

nutrientuptake, etc ; phytoplankton; population dynamics; Show all 3 Subjects
Abstract:
... Almost all biological models use either the Droop or Monod form to describe the resource-based growth of a living organism. Empirical evidence overwhelmingly suggests the Droop form describes data more accurately than the Monod form, however, the Monod form is more popular due to its simplicity. Focusing on phytoplankton, we illustrate the underlying logics behind these two forms via conceptual co ...
