1Wyszukiwanie od początku wyrazu:Wyraz preane znajdzie "preanestetyczny", ale anestetyczny nie znajdzie tego słowa (wyszukiwanie patrzy tylko na początek wyrazów)
-Wykluczanie słów (znak minus):Poprzedzenie wyrazu znakiem - znajdzie wszystkie tytuły NIE zawierające danego słowa, np. -onkologia znajdzie prace bez słowa "onkologia"
"Wyszukiwanie całych fraz (cudzysłów):Cudzysłów powoduje szukanie całych ciągów znaków w tej samej kolejności. Np. "Uniwersytet Medyczny" wyszuka tylko prace z dokładnie tą nazwą, podczas gdy wpisanie bez cudzysłowu może znaleźć "Medyczny Uniwersytet"

Knowledge of manufacturing technology of items from various raw materials not only allows for a better understanding of the spheres of human culture associated with their production but also provides a basis for further conclusions on the functioning of prehistoric communities. Copper-alloy objects might be examined using a wide range of archaeometallurgical methods. In this paper, we would like to focus on the manufacturing technology of banded pseudo-spiral bracelets, using an archaeological experiment, macro- and microscopic analyses of traces on copper-alloy items and computed tomography of artefacts from the Lubnowy Wielkie hoard, dated to the Late Bronze Age, Montelius’ V period, as well as their reconstructions made during the experiment.
Myeloid-derived suppressor cells (MDSCs) play a significant role in the immune system and have been extensively studied in cancer. MDSCs are a heterogeneous population of myeloid cells that accumulate in the tumor microenvironment. Consequently, the high abundance of these cells often leads to immunosuppression, tumor growth, treatment failure, and poor prognosis. Ovarian cancer ranks fifth in cancer deaths among women, accounting for more deaths than any other cancer of the female genital tract. Currently, there is a lack of effective clinical strategies for the treatment of ovarian cancer. Although several studies underline the negative role of human MDSCs in ovarian cancer, this topic is still understudied. The works on MDSCs are summarized here, along with an explanation of why focusing on these cells would be a promising approach for treating …
Salvage treatment for locally recurrent prostate cancer after primary radiotherapy remains a clinical challenge, with multiple modalities— including stereotactic body radiotherapy (SBRT), high-dose-rate (HDR) brachytherapy, and low-dose-rate (LDR) brachytherapy—competing for optimal use. The recent UroGEC expert review in Radiotherapy & Oncology provides a timely synthesis of available evidence and underscores the potential role of brachytherapy in this setting. Here, we contextualize these findings with recently published meta-analyses that expand the evidence base and refine our understanding of salvage outcomes. Updated analyses highlight significant differences across modalities: HDR brachytherapy achieves favorable disease control with low gastrointestinal toxicity, whereas LDR appears to offer superior relapse- free survival in selected subgroups at the cost of higher late genitourinary morbidity. By contrast, SBRT, although attractive for its non-invasiveness, demonstrates lower long-term relapse-free survival when …
Biomaterials are natural or synthetic materials designed to substitute or improve the performance of bone or living tissues. Over the past two decades, bioglass (BG) has emerged as a particularly promising biomaterial, consistently demonstrating its capacity to stimulate bone regeneration and osseointegration. Bioglass composites benefit from the addition of natural or synthetic polymers, which not only boost their mechanical integrity but also make them more versatile in terms of fabrication into different shapes and sizes. Of particular interest is typical polysaccharide, chitosan (Ch), a non-toxic, biocompatible, and biodegradable derived from renewable sources, which naturally possesses antibacterial activity. The strategic combination of bioglass and chitosan leverages their individual strengths to create bioactive composite coatings with significant potential for diverse biomedical applications. These novel multilayer/multicomponent coatings deposited on solid support/implant are being …
Abstract Dental composites are widely used in restorative dentistry; however, their long-term clinical performance is strongly influenced by mechanical and tribological behavior under oral conditions. Understanding the relationship between material structure, surface characteristics, and functional properties is therefore essential. This preliminary methodological study evaluated the mechanical, tribological, and wetting properties of three light-cured dental composites—Enamel Plus HRi, Amaris, and Estelite Asteria—commonly used in clinical practice. The materials were characterized in terms of surface morphology, hardness, Young’s modulus, coefficient of friction, and wear resistance under controlled laboratory conditions. Instrumental indentation and tribological tests were performed, and results were expressed as mean values with standard deviations calculated from multiple measurements. The results demonstrated that filler composition and surface topography affected material performance. Estelite Asteria exhibited the highest hardness (HIT > 300 MPa), …
