The main goal of this cross-sectional study was to assess the relationship between resilience and life satisfaction in women suffering from endometriosis and examine anxiety and depression as mediators in this relationship. The study sample included 349 Caucasian women aged from 18 to 56 years ( = 32.94; SD = 6.

The flexible polyurethane foam hybrids (PUFs) chemically modified by functionalized polyhedral oligomeric silsesquioxanes: octa(3-hydroxy-3-methylbutyldimethylsiloxy)POSS (OCTA-POSS) and 1,2-propanediolizo-butylPOSS (PHI-POSS), was obtained. The resulting foams, which contain 0 to 15 wt % POSS, were characterized in terms of their structure, morphology, density and compressive strength.
View Article and Find Full Text PDFTelomerase is perceived as an immortality enzyme that enables passing the Hayflick limit. Its main function is telomere restoration but only in a limited group of cells, including cancer cells. Since it is found in a vast majority of cancer cells, it became a natural target for cancer therapy.

Titanium (>99.6% purity) and its anodically oxidized modifications, with and without deposited silver nanodendrites regarding its biocompatibility were evaluated. In human gingival fibroblasts and osteoblast cell lines grown on tested samples, the level of expression of genes encoding αV (ITGAV) and β1 (ITGB1) integrin subunits also genes encoding focal adhesion (FAK) and extracellular-signal regulated (ERK) kinases was assessed.

The mechanism of interplay between both diseases remains poorly recognized. This report examines whether COPD may cause a senescence response in human bronchial epithelial cells (HBECs), leading to the progression of LC in a senescence-dependent manner.

Overexpression of PKCε was detected in histological samples from GB, anaplastic astrocytoma, and gliosarcoma and is considered an important marker of negative disease outcome. In multiple studies on GB, autophagy has been shown as a survival mechanism during cellular stress, contributing to resistance against anti-cancer agents.

In situ nanocomposites, obtained through mechanical alloying and traditional powder metallurgy compaction and sintering, show obvious differences to their microstructural analogue. A unique microstructure connected with good mechanical properties reliant on the processing conditions favour the nanoscale range of results of the Ti-TiB in situ MMNC example.

Recently, the effect of different sizes of precursor powders during surface plasma alloying modification on the properties of titanium surface was studied. In this work we show in vitro test results of the titanium (α-Ti) after plasma surface alloying with boron (B). Ti-B nanopowders with 2 and 10wt% B were deposited onto microcrystalline Ti substrate.
View Article and Find Full Text PDFTelomere shortening is associated with cancer development, primarily through the induction of genomic instability. The majority of studies have indicated that individuals with shorter blood telomeres may be at a higher risk of developing various types of cancer. There is increasing evidence that the study of the alterations in telomere length may improve cancer prognosis.

PKCϵ revealed high transforming potential and the ability to increase cell migration, invasion, and metastasis. Zapotin (5,6,2',6'-tetramethoxyflavone), a natural flavonoid, showed chemopreventive and anticancer properties.

View Article and Find Full Text PDFTelomerase is a specialized enzymatic complex responsible for the synthesis of telomeric repeats 5'-TTAGGG-3' localized at the ends of eukaryotic chromosomes. This mechanism prevents shortening of telomeres after each cell division. The enzyme is detected in about 85% of human tumors, but it is not expressed in normal cells or its expression is significantly lower.
