Poor water solubility and low bioavailability of flavonoids present significant barriers to their development and application. To address these challenges, this study explores the use of crystalline solid dispersions (CSDs) to reduce drug crystalline size and enhance in vivo bioavailability.

International Journal of Modern Physics A, 2009
Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet divergences are nearly inevitable. Here, we investigate a theory that only displays a finite number of degrees of freedom in compact sections of space-time. In finite domains,

Crystallins and Their Complexes
2019The crystallins (α, β and γ), major constituent proteins of eye lens fiber cells play their critical role in maintaining the transparency and refractive index of the lens. Under different stress factors and with aging, β- and γ-crystallins start to unfold partially leading to their aggregation.

Advanced Drug Delivery Reviews, 2001
Many drugs exist in the crystalline solid state due to reasons of stability and ease of handling during the various stages of drug development. Crystalline solids can exist in the form of polymorphs, solvates or hydrates. Phase transitions such as polymorph interconversion, desolvation of solvate, formation of hydrate and conversion of crystalline to ...

Despite more than a century of organolead chemistry, all isolable organolead compounds have thus far been confined to Pb-C single bonds. Here we disclose the synthesis, structural authentication, and reactivity of room-temperature-stable plumbynes ([(CH2)(NDipp)]2PCPbAr; Ar = C6H3-2,6-Mes2 or C6H3-2,6-Trip2; Mes = mesityl; Trip = C6H2-2,4,6-iPr3)─the ...

Alpha A and alpha B-crystallins are a major protein component of the mammalian eye lens. Being a member of the small heat-shock protein family they possess chaperone-like function. The alpha-crystallins and especially alpha B is also found outside the lens having an extensive tissue distribution. Alpha B-crystallin is found to be over-expressed in many

Applied Optics, 1966
A survey of crystalline solid lasers is presented. Crystalline host materials are described, pointing out their characteristics pertinent for laser systems. Rare earth and transition metal impurities operated as lasers are tabulated and the role of sensitization in increasing the overall efficiency of laser systems is described.

The nature of crystallinity of α-crystallin preparation of bovine lenses
Experimental Eye Research, 1972Abstract α-crystallin prepared by isoelectric precipitation yielded well-defined powder diagrams in X-ray diffraction. The reflections could be indexed as coming from a hexagonal primitive unit cell with the dimension of a = b = 8·17 A, c = 7·52 A and γ = 120°. The real unit cell is probably a multiple of this.
