Examination of Aggregate Formation upon Simultaneous Dissolution of Methacrylic Acid Copolymer LD Enteric Coating Agent, Pharmaceutical Additives, and Zwitterionic Ingredients.
In this study, we have clarified the factors causing aggregate formation, focusing on the role of pharmaceutical additives and electrostatic interaction. Co-suspension of enteric-coated proton pump inhibitor (PPI) esomeprazole magnesium hydrate with levofloxacin resulted in aggregate formation, whereas the non-enteric-coated PPI vonoprazan fumarate did not. A comparison of pharmaceutical additive in the two PPIs highlighted polysorbate 80 and methacrylic acid copolymer LD as candidates causing aggregation. When these pharmaceutical additives were added to levofloxacin, only methacrylic acid copolymer LD induced aggregate f...

Stripping and plating magnesium metal anode in bromide-based non-nucleophilic electrolytes.
We present here a new electrolyte formulation of non-nucleophilic HMDS magnesium containing bromide as halide instead of chloride, obtained via a simple and straightforward synthesis route and investigate the electrochemistry of magnesium through plating and stripping in three different HMDSBr-based electrolytes: Mg(HMDS)Br, Mg(HMDS)Br-BEt3 and Mg(HMDS)Br-AlEt3 dissolved in THF. We determine the different magnesium species in the electrolytes using NMR. Weak electron-withdrawing Lewis acids, BEt3 and AlEt3 were used intentionally and their impacts investigated. Contrary to expectation, substitution of chloride by bromide d...

Contrasting patterns of functional diversity in coffee root fungal communities associated with organic and conventionally-managed fields.
Abstract The structure and function of fungal communities in the coffee rhizosphere is shaped by crop environment. Because coffee can be grown along a management continuum from conventional application of pesticides and fertilizers in full sun to organic management in a shaded understory, we used coffee fields to hold host constant while comparing rhizosphere fungal communities in markedly different environmental conditions with regard to shade and inputs. We characterized the shade and soil environment in 25 fields under conventional, organic or transitional management in two regions of Costa Rica. We amplified t...

Characterization and application of a family B DNA polymerase from the hyperthermophilic and radioresistant euryarchaeon Thermococcus gammatolerans.
Abstract Thermococcus gammatolerans is anaerobic euryarchaeon which grows optimally at 88 °C and its genome encodes a Family B DNA polymerase (Tga PolB). Herein, we cloned the gene of Tga PolB, expressed and purified the gene product, and characterized the enzyme biochemically. The recombinant Tga PolB can efficiently synthesize DNA at high temperature, and retain 93% activity after heated at 95 °C for 1.0 h, suggesting that the enzyme is thermostable. Furthermore, the optimal pH for the enzyme activity was measured to be 7.0-9.0. Tga PolB activity is dependent on a divalent cation, among which magne...

Impact of screw thread shape on stress transfer in bone: a finite element study.
In this study, the effect of thread profile on stress transfer in a magnesium fixation was simulated using a 2-D finite element model. Modified stress parameters from a previous study were used to estimate stress transfer across three thread profiles. Results showed highest stress transfer in trapezoidal-shaped magnesium screw thread. In accordance, this study corroborates the potential for magnesium as an ultimate screw material to eliminate progressive screw loosening.

Magnesium Acts as a Second Messenger in the Regulation of NMDA Receptor-Mediated CREB Signaling in Neurons
AbstractExtracellular magnesium ion ([Mg2+]) is a well-known voltage-dependent blocker of NMDA receptors, which plays a critical role in the regulation of neuronal plasticity, learning, and memory. It is generally believed that NMDA receptor activation involves in Mg2+ being removed into extracellular compartment from the channel pore. On the other hand, Mg2+ is one of the most abundant intracellular cations, and involved in numerous cellular functions. However, we do not know if extracellular magnesium ions can influx into neurons to affect intracellular signaling pathways. In our current study, we found that extracellula...

Hexameric structure of the ATPase motor subunit of magnesium chelatase in chlorophyll biosynthesis
AbstractMagnesium chelatase (MgCh) is a heterotrimeric enzyme complex, composed of two AAA+ family subunits that can assembly into a double ring structure and a large catalytic subunit. The small AAA+ subunit has ATPase activity and can self ‐oligomerize into a ring structure, while the other AAA+ subunit lacks independent ATPase activity. Previous structural studies of the ATPase motor subunit of MgCh from a bacteriochlorophyll‐synthesizing bacterium have identified a unique ATPase clade, but the model of oligomeric assembly is unc lear. Here we present the hexameric structure of the MgCh ATPase motor subunit from the...

The crystal structure, morphology and mechanical properties of diaquabis(omeprazolate)magnesium dihydrate
The crystal structure of diaquabis(omeprazolate)magnesium dihydrate (DABOMD) in the solid state has been determined using single-crystal X-ray diffraction. Single crystals of DABOMD were obtained by slow crystallization in ethanol with water used as an antisolvent. The crystal structure shows a dihydrated salt comprising a magnesium cation coordinating two omeprazolate anions and two water molecules (W1) that are strongly bound to magnesium. In addition, two further water molecules (W2) are more weakly hydrogen-bonded to the pyridine nitrogen atom of each omeprazolate anion. The crystal structure was utilized to estimate k...

Potential Slow Release Fertilizers Based on K2MgSiO4 Obtained from Serpentinite
In this work, a potassium magnesium silicate mineral based on phase K2MgSiO4 was prepared from serpentinite rock and studied as a potential K and Mg slow-release fertilizer. The material was prepared by impregnation of serpentinite/KOH and calcination at 700 °C to produce K2MgSiO4 phase, olivine and forsterite. The release patterns of K and Mg in the stirred-flow trial and leaching through the soil columns showed that K2MgSiO4-based materials released K on lower rates than KCl and MgSO4.7H2O, however, there was no evidence of Mg release. The extraction with 1 mol L-1 NH4OAc showed a considerable content of Mg and K for...
