Drained cultivated peatlands have been an essential agricultural resource for many years. To slow and reduce the degradation of these soils, which increases with drainage, use plant-based amendments (straw, wood chips, biochar) has proposed. Literature on effects such in is scarce, questions raised regarding impact this practice nutrient cycling, particularly nitrogen (N) dynamics. By means a s...
Inhalation Ciprofloxacin HCl microspheres were formulated with combination of alginate and kappa carrageenan a total 1% (F1), 1.5% (F2), 2% (F3). Aim this research is to examine effect polymer concentration on characteristics, release, lung deposition microspheres. Microspheres characterized including loading, efficiency, yield, size, moisture content, mucoadhesivity, release. Deposition was st...
Controlled-release fertilizers are interesting alternatives to current commercial chemical fertilizers, which present a higher nutrient release rate, and can negatively impact the ecosystem. In this work, two urea controlled-release fertilizer types were manufactured from carnauba wax (CW), granulated (U), natural sodium bentonite (Bent-R Bent-Na, respectively). first type, mechanochemical meth...
the present investigation was focused to formulate semi-solid capsules (sscs) of hydrophobic drug telmisartan (tlms) by encapsulating semi-solid matrix of its solid dispersion (sd) in hpmc capsules. the combinational approach was used to reduce the lag time in drug release and improvise its dissolution. sds of tlms was prepared using hot fusion method by varying the combinations of pluronic-f68...
Controlled release fertilizers (CRF) are produced with different rates and durations of nutrient release to cater to different crops with wide ranges of nutrient requirements. A rapid technique is needed to verify the label specifications of nutrient release rate and duration. Polymer-coated urea (PCU) (43% nitrogen [N]) and polymer-coated N, phosphorus (P), potassium (K) (PC_NPK; 14-14-14) fer...
How can synapses change the amount of neurotransmitter released during synaptic plasticity? Although release in general is intensely investigated, its determinants during plasticity are still poorly understood. As a model for plastic strengthening of synaptic release, we here use the well-established presynaptic homeostatic compensation during interference with postsynaptic glutamate receptors ...
OBJECTIVES We investigated whether a higher serum erythropoietin (EPO) level in patients with acute myocardial infarction (MI) subjected to successful primary percutaneous coronary intervention (PCI) can predict a smaller infarct size determined by creatine kinase (CK) release. BACKGROUND Erythropoietin has been shown to protect cardiomyocytes from ischemia-reperfusion injury in rodents. ME...
This study focused on the fabrication, characterization, and release properties of electrospun tea polyphenol (TPP) loaded porous core-shell structured fibers. The morphology, structure and properties of the electrospun TPP loaded porous core-shell fibers were investigated by a combination of Fourier transformation infrared spectroscopy (FTIR), scanning electron microscopy (SEM), contact angle ...
