Keratins K1 and K10 are the most abundant proteins in the upper epidermis where they polymerize to form intermediate filaments (IFs). In addition to their well-established function in providing epidermal stability, K1/K10 (i.e. the dimer between K1 and K10) IFs are supposed to be important for terminal epidermal differentiation and barrier formation. It was previously shown that the imbalanced ...

Acid stimulation to enhance the permeability of geological reservoirs is oldest technique still in use. sometimes fails due either poor stability acid or an undesirable influence on clay minerals reservoir formation. Among others, a formation govern reservoir. The interaction investigated biodegradable chelating agents (BCA1, BCA2 and BCA3) kaolinite-natural (KN) montmorillonite-K10 (MM) hydrot...

Vitamin D3 analogues are a first-line treatment of chronic plaque psoriasis, but so far, comparative clinical studies on calcipotriol and calcitriol ointment are sparse, and in particular no comparative studies are available on cell biological effects of these compounds in vivo. Using flow cytometric assessment, we investigated whether these compounds had different effects on the composition an...

Polyvinyl chloride (PVC)/organic-montmorillonite composites were prepared by melt intercalation. Their structures and properties were investigated with X-ray diffraction (XRD), differential scanning calorimetry (DSC) and mechanical testing. The results showed that PVC chains could be intercalated into the gallery of organically modified montmorillonite to form exfoliated PVC/organic-montmorillo...

A silicotungstic acid (STA) was successfully impregnated onto K10 montmorillonite (MMT) in an effort to improve the properties of SPEEK membrane. Several characterizations such as Fourier transform infrared (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were carried out in order to confirm the entrapment of STA molecule onto MMT. It was found that the ST...

The [Co(Me(2)Salen)(PBu(3))(OH(2))]BF4 and [Co(Me(2)Salen)(PPh(3))(Solv)]BF(4), complexes were synthesized and characterized by FT-IR, UV-Vis, (1)H NMR spectroscopy and elemental analysis techniques. The coordination geometry of [Co(Me(2)Salen)(PPh(3))(H(2)O)]BF(4) was determined by X-ray crystallography. It has been found that the complex is containing [Co(Me(2)Salen)(PPh(3))(H(2)O)]BF(4) and ...

The montmorillonite sample from Heping, China had been studied by chemical analysis, XRD, IR, AFM and MAS NMR. The results showed that acid concentration had much influence on surface structure of montmorillonite. When the acid concentration reached 2M, the Q3Si structure in silica-oxygen tetrahedron recombined, some Q3Si structure in montmorillonite transformed to distortion Q3Si structure and...

The aim of this study was to validate the Dutch version of the Kessler-10 (K10) as well as an extended version (EK10) in screening for depressive and anxiety disorders in primary care. Data are from 1,607 participants (18 through 65 years, 68.8% female) of the Netherlands Study of Depression and Anxiety (NESDA), recruited from 65 general practitioners. Participants completed the K10, extended w...
