The Occurrence and Outcomes of Cemento-Osseous Dysplasias (COD) in the Jaw Bones of the Population of Lower Silesia, Poland.

Cemento-osseous dysplasias (CODs) are rare lesions of the jawbone. Their occurrence, localization, type, size, and shape can vary between cases. This fibro-osseous lesion is typically found in the jaw near tooth-bearing areas and is often asymptomatic, discovered incidentally, and may be associated with the periapical region of the teeth.

Correlation between Periostin Expression and Pro-Angiogenic Factors in Non-Small-Cell Lung Carcinoma.

The role of periostin (POSTN) in remodeling the microenvironment surrounding solid tumors and its effect on the tumor cells in non-small-cell lung carcinoma (NSCLC) have not yet been fully understood. The aim of this study was to determine the relationship between POSTN expression (in tumor cells [NSCLC cells] and the tumor stroma) and pro-angiogenic factors (CD31, CD34, CD105, and VEGF-A) and microvascular density (MVD) in NSCLC. In addition, these associations were analyzed in individual histological subtypes of NSCLC (SCC, AC, and LCC) and their correlations with clinicopathological factors and prognosis were examined.

Searching for a relationship between the elemental composition of archaeological bones and the occurrence of caries.

Background: Although the macroscopic assessment of dental caries and the assessment of bone elemental composition are quite different, efforts can be made to identify commonalities in the assessment of health and nutritional quality. Both indicators are correlated with dietary habits and are dependent on taphonomic processes occurring in the postmortem substrate. However, teeth exhibit structural resilience of their hard tissues to adverse environmental factors.

Pulsed electric field induces exocytosis and overexpression of MAGE antigens in melanoma.

Nanosecond pulsed electric field (nsPEF) has emerged as a promising approach for inducing cell death in melanoma, either as a standalone treatment or in combination with chemotherapeutics. However, to date, there has been a shortage of studies exploring the impact of nsPEF on the expression of cancer-specific molecules. In this investigation, we sought to assess the effects of nsPEF on melanoma-specific MAGE (Melanoma Antigen Gene Protein Family) expression.

Vitrification of feline ovarian tissue: Comparison of protocols based on equilibration time and temperature.

Global contraction of biodiversity pushed most members of Felidae into threatened or endangered list except the domestic cat (Felis catus) thence preferred as the best model for conservation studies. One of the emerging conservation strategies is vitrification of ovarian tissue which is field-friendly but not yet standardized. Thus, our main goal was to establish a suitable vitrification protocol for feline ovarian tissue in field condition.

New Equations for the Estimation of the Age of the Formation of the Harris Lines.

Harris Lines (HLs) are transverse, sclerotic lines that can be visualized by X-ray imaging and that occur in long bones, most commonly in the tibia and femur. HLs are associated with disrupted bone mineralization during endochondral ossification, affecting the normal growth process. The etiology of HLs is debated, with some claims linking their presence to detrimental factors such as inflammation, malnutrition, alcohol abuse, and diseases.

Histological analysis of forearm superficial veins structure.

Background: The connection between the basilic and cephalic veins of the forearm shows considerable interindividual variation. Depending on its form, the most common types of venous connections are M-, N- or Y-shaped. This study aims to compare the metric traits of the basilic and cephalic veins and the relative content of smooth muscle/collagen fibers/elastic fibers in their walls and to determine the differences between the forearm venous systems.

Ultrastructural changes in feline oocytes during ovary storage for 24- and 48-hours.

Despite established microscopic markers of feline oocyte quality, little is known about their ultrastructural traits. To the best of our knowledge, there is no published report analysing the effect of 24 and 48 h ovarian storage time on the domestic cat oocytes characteristics at the ultrastructural level. Oocytes (n = 30) were classified using the light microscopy as good or bad quality and then proceeded for TEM observations.

Morphology of the antegonial notch and its utility in the determination of sex on skeletal materials.

A number of criteria for the assessment of biological sex, which are applied to living or recently deceased individuals, have been developed, such as genetic, chromosomal, gonadal, hormonal, and phenotypic criteria. Features of a metric and descriptive nature are used to assess the sex of skeletal materials. The diagnostic features of the skull are concentrated in the craniofacial region and around the eye sockets.

Identifying the Molecular Mechanisms and Types of Cell Death Induced by - and -Silica Nanoparticles in Endothelial Cells.

The term "nanosilica" refers to materials containing ultrafine particles. They have gained a rapid increase in popularity in a variety of applications and in numerous aspects of human life. Due to their unique physicochemical properties, SiO nanoparticles have attracted significant attention in the field of biomedicine.

Nutritional reconstruction in an early modern population: Searching for a relationship between dental microwear and bone element composition.

Background: Observing the microwear patterns of the dental crowns enamel surface can provide information on the ingredients and structure of the food consumed, but also on eating habits and lifestyle. Major role in reconstructing the diet and lifestyle of past populations is played by the analysis of alkaline earth metals, such as strontium, barium, zinc and calcium. Ba and Sr are indicators of the consumption of vegetables, plants (cereals and legumes) and marine organisms.

Cardiovascular Risk and Endothelial Dysfunction in Primary Sjogren Syndrome Is Related to the Disease Activity.

The aim of our study was to evaluate if endothelial-dysfunction (ED) occurs in patients with primary Sjogren syndrome (pSS) and whether it is associated with the disease characteristics and activity. A total of 46 patients with pSS and 30 controls, without known cardiovascular disease, were enrolled in this study. A flow-mediated-dilation (FMD) of the brachial artery, plasma concentrations of the nitric oxide (NO) metabolic pathway (ADMA, L-arginine, SDMA, cGMP), and markers of endothelial inflammatory function (PAI-1, sE-selectin) and angiogenesis (angiostatin, VEGF) were analyzed.

Estimation of age at onset of linear enamel hypoplasia. New calculation tool, description and comparison of current methods.

Enamel Hypoplasia (EH) is known to be a useful indicator for wide range of detrimental factors in early childhood in past populations, such as nutritional disturbances, mechanical trauma, disease, metabolic, and/or genetic disorders. EH may be divided into three categories: pits, grooves, and lines, where the last two are referred to as "Linear Enamel Hypoplasia" (LEH). The regularity of enamel formation allows retrospective determination of the age of LEH formation.

Antlerogenic stem cells extract accelerate chronic wound healing: a preliminary study.

Background: Chronic wounds constitute a significant medical and social problem. Chronic wound treatment may be supported by various techniques, such as negative pressure therapy, phototherapy or stem cells therapy, yet most of those supporting therapies need more evidence to be used for standard wound care. Current study covers the use of sonicated Antlerogenic Stem Cells (ASC) extract on chronic wounds.
