Maintenance of physiologic phosphate balance is important for essential cellular functions [1]. Dysregulation of the phosphate balance in the form of hypophosphataemia can lead to the development of myopathy, cardiac dysfunction, haematological abnormalities and bone mineralization defects [1]. In contrast, hyperphosphataemia can cause vascular and soft tissue calcification [2,3]. Studies have ...

In this study, we demonstrate an effective approach based on a simple processing method to improve the thermomechanical properties of graphene polymer composites (GPCs). Edge-selectively functionalized graphene (EFG) was successfully obtained through simple ball milling of natural graphite in the presence of dry ice, which acted as the source of carboxyl functional groups that were attached to ...

Phosphatidylinositol-(4,5)-bisphosphate [PI(4,5)P(2)] plays a key role in the modulation of actin polymerization and vesicle trafficking. These processes seem to depend on the enrichment of PI(4,5)P(2) in plasma membrane domains. Here, we show that PI(4,5)P(2) does not form domains when in a fluid phosphatidylcholine matrix in the pH range of 4.8-8.4. This finding is at variance with the sponta...

We studied with biochemical and immunofluorescent techniques the interactions between the actin microfilament and tubulin microtubule cytoskeleton and Na+/P1 co-transport in opossum kidney cells, a line with proximal tubular characteristics. On brief (5 min) incubation of the cells with a low (0.1 mM) concentration of Pi, a rapid F-actin depolymerization takes place, which fails to occur in cel...

Recent work arXiv:1812.03138 [nucl-th] conjectured that entanglement is minimized in low-energy hadronic scattering processes. It was shown the minimization of power (EP) baryon-baryon $S$-matrix implies novel spin-flavor symmetries are distinct from large-$N_c$ QCD predictions and confirmed by high-precision lattice simulations. Here conjecture minimal investigated for processes involving pion...

Laser-induced graphene (LIG) has gained considerable attention recently due to its unique properties and potential applications. In this study, we investigated using LIG in polyimide (PI) as a material for antenna The LIG-−PI composite was prepared by facile picosecond laser (1064 nm) irradiation process, which resulted conductive network within the PI matrix. Furthermore, formation confirmed R...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

The interaction of vascular smooth muscle cells (SMCs) and extracellular matrix plays important roles in vascular remodeling. We investigated the signaling pathways involved in SMC-induced matrix contraction and SMC migration in three-dimensional (3D) collagen matrix. Matrix contraction is inhibited by the disruption of actin filaments but not microtubules. Therefore, we investigated the roles ...

Let P={Pij; i, j=l, 2, ... , r} be the transition matrix of a stationary, regular Markov chain C with r states and a={ai; i=l, 2, ... , r} be its limiting vector which represents the stationary distribution of the chain. Suppose that there is another regular Markov chain C' with the transition matrix pI ={p;j} and the limiting vector a' ={a;}. If pI is close to P, we can expect that a' is also ...

Brushless DC motors (BLDC) are widely used in industrial areas. The BLDC motors are driven either by indirect ACAC converters or by direct AC-AC converters. Direct AC-AC converters i.e. matrix converters are used in this paper to drive the three phase BLDC motor and it eliminates the bulky DC link energy storage element. A matrix converter converts the AC power supply to an AC voltage of variab...
