How to develop a bio-based phosphorus mining strategy for eutrophic marine sediments: Unlocking native microbial processes for anaerobic phosphorus release
This study examined the anaerobic release of phosphorus (P) from two different Baltic Sea sediments (B and F), focusing on the impact of initial concentration of externally introduced waste-derived volatile fatty acids (VFA) as the carbon source, temperature, pH, and mixing conditions. The first batch bioreactor set was operated to demonstrate the effect of VFA on anaerobic P release at different concentrations (1000-10000 mg/L as COD) at 20 °C. A notable P release of up to 15.85 mg/L PO4-P was observed for Sediment B at an initial carbon concentration of 10000 mg COD/L. However, VFA consumption in the bioreactors was min...

Evolutionary formation of melatonin and vitamin D in early life forms: insects take centre stage
Biol Rev Camb Philos Soc. 2024 Apr 30. doi: 10.1111/brv.13091. Online ahead of print.ABSTRACTMelatonin, a product of tryptophan metabolism via serotonin, is a molecule with an indole backbone that is widely produced by bacteria, unicellular eukaryotic organisms, plants, fungi and all animal taxa. Aside from its role in the regulation of circadian rhythms, it has diverse biological actions including regulation of cytoprotective responses and other functions crucial for survival across different species. The latter properties are also shared by its metabolites including kynuric products generated by reactive oxygen species o...

Preparation of nano-silver containing black phosphorus based on quaternized chitosan hydrogel and evaluating its effect on skin wound healing
Int J Biol Macromol. 2024 Apr 27:131950. doi: 10.1016/j.ijbiomac.2024.131950. Online ahead of print.ABSTRACTHydrogels with favorable biocompatibility and antibacterial properties are essential in postoperative wound hemorrhage care, facilitating rapid wound healing. The present investigation employed electrostatic adsorption of black phosphorus nanosheets (BPNPs) and nano‑silver (AgNPs) to cross-link the protonated amino group NH3+ of quaternized chitosan (QCS) with the hydroxyl group of hyaluronic acid (HA). The electrostatic interaction between the two groups resulted in the formation of a three-dimensional gel network...

Control of phosphorus release from sediment by iron/aluminum co-modified zeolite: efficiency, mechanism, and response of microbial communities in sediment
Environ Sci Pollut Res Int. 2024 Apr 30. doi: 10.1007/s11356-024-33482-9. Online ahead of print.ABSTRACTThe efficiency of iron/aluminum co-modified zeolite (FeAl-Z) covering and amendment for controlling the internal loading of phosphorus (P) from sediment to the overlying water (OW) and its controlling mechanism were explored. The response of the composition of sedimentary microbial communities in sediment and their function to the FeAl-Z capping and amendment was also examined. FeAl-Z showed good removal performance for phosphate in aqueous solution. The maximum phosphate adsorption quantity for FeAl-Z at pH 7 attained 1...

Cyanopeptides occurrence and diversity in a brazilian tropical reservoir: exploring relationships with water quality
This study aimed (i) to determine the dynamics of MCs and other cyanopeptides in a tropical reservoir, (ii) to investigate the correlation between peptides and potential cyanotoxin producers (iii) identifying the possible abiotic factors that influence the peptides. We analyzed, monthly, eight MC variants (MC-RR, -LA, -LF, -LR, -LW, -YR, [D-Asp3]-RR and [D-Asp3]-LR) and other peptides in 47 water samples collected monthly, all season long, from two sampling sites in a tropical eutrophic freshwater reservoir, in southeastern Brazil. The cyanopeptides were assessed by liquid chromatography-tandem mass spectrometry (LC-MS/MS)...

221. Brain Phosphorus Bioenergetics Improves in Depressed Subjects After Eight Weeks of Creatine Monohydrate Supplementation
Depression is associated with altered brain bioenergetics. Lower brain phosphocreatine (PCr) levels have been associated with poor outcomes in response to antidepressant treatment, which may be related to high recurrence of depression. PCr is an indicator of high-energy stores and buffering capacity. In rats, creatine monohydrate (Cr) significantly reduces depression-like behavior. In the present study, we have sought to measure the mechanistic marker, PCr and symptom changes over 8-weeks of Cr vs. (Source: Biological Psychiatry)

Effect of dietary supplementation of plantain herb, lemongrass and their combination on milk yield, immunity, liver enzymes, serum, and milk mineral status in dairy cows
CONCLUSIONS: Both plantain and lemongrass improved dairy cows' DM consumption and milk yield. Plantain and/or lemongrass enhanced the immune system and liver health, but not serum and milk calcium and phosphorus level. Lemongrass and a combination of plantain and lemongrass increased the serum and milk zinc concentrations.PMID:38680813 | PMC:PMC11055577 | DOI:10.5455/javar.2024.k764 (Source: Adv Data)

Examining characteristics and sampling methods of phosphor dynamics in lowland catchments
This study aims at analyzing the characteristics governing the concentrations of four key water quality parameters (total phosphorus, orthophosphate, particulate phosphate, and suspended solids) in two lowland catchments: the 50 km2 catchment of the Kielstau, Germany, and its 7 km2 tributary, the Moorau, which are dominated by agricultural land use. To this end, different sampling methods, particularly high-resolution precipitation event-based sampling and daily mixed samples, are conducted and evaluated, and their effectiveness is compared. The identification of sources and characteristics that affect phosphorus and suspe...
