Opis:
Poland, by 2020 430,000 Mg of hazardous waste will be formed annually by the combustion of waste. This waste must be properly managed so as not to endanger the environment. One promising way to manage selected waste is to process it in the synthesis of materials characterised by sorption properties. The results presented in this paper concern the possibility of producing sorbents from waste materials marked with codes 190112 and 190114, which came from two waste incineration plants in Poland. Alkaline activation was performed using two methods: a) hydrothermal, in a solution of 8 M NaOH at 75°C for 24 h; and b) in an autoclave, using a solution of 2 M NaOH at 140°C for 6 h. XRD analyses led to the identification of materials after synthesis of the following zeolite phases: analcime, chabazite and thomsonite. chabazite and analcime can be valuable absorbent materials.

Opis:
Due to late diagnosis, ovarian cancer is the most deadly gynecologic malignancy. Inflammation is one of the risk factors of ovarian cancer and the inflammatory response implicates all stages of tumorigenesis. The purpose of this study was to analyze the concentration of molecules, which can take part in malignant processes. We analyzed patients with ovarian cancer, with endometriosis and healthy controls. Thirty-seven analytes were measured in serum using BioPlex Pro Human Inflammation Panel. We were able to detect 28 of the proteins among the studied groups. We found a significant increase in 22 of the tested molecules (BAFF, Chitinase3-like 1, IFN-alpha2, IFN-beta, IFN-gamma, IFN-lambda2, IFN-lambda1, gp130, IL-2, IL-12 (p40), IL-11, IL-32, IL-35, MMP3, Osteocalcin, Pantraxin-3, sCD163, TNFRSF8, sIL-6Ralpha, STNF-R1, STNF-R2, and TSLP) in the ovarian cancer group in comparison to the healthy controls. Two of them (IL-20, MMP1) did not show significant differences between groups. Moreover, we identified decreased concentrations of APRIL and osteopontin in ovarian cancer vs. healthy controls. While this study is a preliminary report, we hope this will encourage a further use of multiplex analysis in ovarian cancer biomarker research.

Opis:
The presented work describes the method of measuring surface topography with application of BRDF (bidirectional reflectance distribution function), ellipsometry and spectrophotometry. This non-contact method enables measurement and analysis of large area surfaces, such as plasters and facades. A standard method of topography analysis does not describe sufficiently all of the interesting features. The visual aspect of the surface evaluation is very important from the functional and utilitarian point of view. The proposed methods of surface analysis enable not only the quantitative evaluation but also indirectly the qualitative properties (visual aspects).

Opis:
Currently, additive technology is becoming increasingly popular in different areas, including its applications in construction industry. The main aim of the chapter is to show the selected applications of 3D printing technology in the construction industry and the usage of this technology on distinct stages of a construction project, from architectural design to performance of residential buildings and other civil engineering constructions. The chapter is based on a critical analysis of the literature sources, as well as the authors' experiences. The data collected are supported by selected case studies from five projects. The main findings show that 3D printing brings a lot of advantages in the construction industry, for instance: low labour costs, less waste, and high efficiency, but it still requires development and optimization.

Opis:
Parathyroid hyperactivity is the state of over-production and PTH secretion [1]. The most common cause of primary hyperparathyroidism is parathyriod adenoma - about 80% of cases, the remaining are parathyroid hyperplasia around 15%cases [2] [3], and in 1-5% of cases, cancer [2] [3] [4] [5]. The disease is diagnosed inabout 40 people in 100,000 [5] [6] [3] [7]. The most common cause of adenoma is the mutation in gene MEN 1. Less than 5% of cases are chronichyperparathyroidism, which is a component of the MEN 1 MEN 2a endocrine adenocarcinoma syndrome [1]. Excess PTH in the body leads to increased mobilization of calcium from the bones, and henceincreased osteolysis, what also increases the absorption of calcium from thedigestive system, as well as an increased amount of phosphate excretion in the urine. Clinical picture of the disease is multiform and often runs in a latent form. Most often the diseaseoccurs in the form of osteoporosis, chronic recurrent kidney stones, and is also commonpyelonephritis on the basis of urolithiasis. The disease may be accompanied by: dysphagia, abdominal pain, metallic taste in the mouth, persistent constipation. In addition, from the systemnervous: dizziness and headaches, disturbances of consciousness. Arrhythmia the form of additional contractions and paroxysmal tachycardia. Osteolysis, osteoporosis and pathological fractures [1]. The purpose of this article is to bring closer to the reader case of 33 years old woman with primary hyperparathyroidism on the adenoma.
