ROC analysis of selected matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in psoriatic patients.

Introduction: Psoriasis is a common, chronic inflammatory disease characterised by typical scaly skin lesions. The role of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in the pathogenesis and development of this condition have been repeatedly emphasised in available literature.

Aim: ROC analysis of selected MMPs (MMP-2, MMP-3, MMP-9, MMP-12, TIMP-2) and TIMPs (TIMP-2, TIMP-3) in psoriasis patients.

Narrowband ultraviolet B light treatment changes plasma concentrations of MMP-3, MMP-9 and TIMP-3 in psoriatic patients.

Background: Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are thought to be associated with the pathogenesis and spread of psoriatic disease. This study was designed to investigate the plasma levels of MMP-3, MMP-9 and TIMP-3 in plaque psoriasis patients prior to and following a course of ultraviolet B narrowband treatment with respect to disease advancement.

Methods: Plasma samples of 49 patients suffering from plaque psoriasis and 40 healthy volunteers were evaluated.

Protective influence of hyaluronic acid on focal adhesion kinase activity in human skin fibroblasts exposed to ethanol.

Aim: The aim of this study was to evaluate the effect of ethanol and hyaluronic acid (HA) on cell survival and apoptosis in cultured human skin fibroblasts. Regarding the mechanism of ethanol action on human skin fibroblasts, we investigated cell viability and apoptosis, expression of focal adhesion kinase (FAK), and the influence of HA on those processes.

Materials And Methods: Studies were conducted in confluent human skin fibroblast cultures that were treated with 25 mM, 50 mM, and 100 mM ethanol or with ethanol and 500 µg/mL HA.

Hyaluronic acid abrogates ethanol-dependent inhibition of collagen biosynthesis in cultured human fibroblasts.

Introduction: The aim of the study was to evaluate the effect of ethanol on collagen biosynthesis in cultured human skin fibroblasts, and the role of hyaluronic acid (HA) in this process. Regarding the mechanism of ethanol action on human skin fibroblasts we investigated: expression of β1 integrin and insulin-like growth factor 1 receptor (IGF-IR), signaling pathway protein expression: mitogen-activated protein kinases (MAPKs), protein kinase B (Akt), nuclear factor kappa B (NF-κB) transcription factor, cytotoxicity assay and apoptosis, metalloproteinase activity, as well as the influence of HA on these processes.

Materials And Methods: Collagen biosynthesis, activity of prolidase, DNA biosynthesis, and cytotoxicity were measured in confluent human skin fibroblast cultures that have been treated with 25, 50, and 100 mM ethanol and with ethanol and 500 µg/mL HA.

Influence of caffeine and hyaluronic acid on collagen biosynthesis in human skin fibroblasts.

Aim: The aim of this study was to evaluate the effect of caffeine on collagen biosynthesis in human skin fibroblasts and the influence of hyaluronic acid (HA) on this process.

Materials And Methods: Collagen, [(3)H]-thymidine incorporation, and prolidase activity were measured in confluent human skin fibroblast cultures that had been treated with 1, 2, and 5 mM caffeine and with caffeine and 500 μg/mL HA. Western immunoblot analysis was performed to evaluate expression of β1-integrin receptor, insulin-like growth factor receptor phospho-Akt protein and mitogen-activated protein kinase (phospho-extracellular signal-regulated kinase).

A comparative study of internal laser-assisted and conventional liposuction: a look at the influence of drugs and major surgery on laboratory postoperative values.

Background: Liposuction is a type of aesthetic surgery that has been performed on humans for decades. There is not much literature addressing the subject matter of pre- and post-surgery blood parameters, although this information is rather interesting. Documentation on patients who received laser-assisted liposuction treatment is particularly scarce.

[Anti-cancer properties epigallocatechin-gallate contained in green tea].

Numerous in vivo and in vitro studies point to the possibility of using green tea's catechins in chemoprevention of cancer. Recent studies show the inhibitory effects of epigallocatechin gallate on the growth of existing tumors including breast cancer, skin cancer and gastrointestinal tract cancers. Another mode of action of biologically active compounds in green tea involves inhibiting the neoplastic process.
