Abstract

O b j e c t i v e s: Periapical inflammation is one of the most common pathologies within the jaws, leading to the destruction of periodontal ligaments, bone resorption and the formation of periapical granulomas or radicular cysts. The final diagnosis can be made only on the basis of histopathological examination. The aim of the study was to assess the conformity between clinical and histopathological diagnosis of inflammatory periapical lesions treated with apicoectomy.
M a t e r i a l s a n d M e t h o d s: The case histories of 52 patients subjected to surgical treatment at the Clinic of Conservative Dentistry with Endodontics between 2008 and 2018 were analyzed. Demographic data (age, gender), clinical (radiological) diagnosis, and data on the presence of sinus tracts and causal tooth were obtained from patients’ records. R e s u l t s: In the light of clinical and radiological examination, 32 (61.5%) periapical granulomas, 18 (34.6%) radicular cysts and 2 (3.9%) periapical scars were diagnosed, whereas the result of histopathological examination revealed granuloma in 34 (65.4%) cases and in 18 (34.6%) — radicular cyst. For clinical diagnosis of granuloma, the result coincided with the result of the histopathological examination in 28 cases, and in the case of cysts in 14. The analysis showed a significant relationship between the clinical and histopathological diagnoses (p <0.05).
C o n c l u s i o n s: The study emphasizes the importance of histopathological assessment for the proper diagnosis of periapical lesions.
C l i n i c a l R e l e v a n c e: The article emphasizes the high importance of histopathological examination for the correct diagnosis of chronic inflammatory periapical lesions.

Abstract

Four tomato (Lycopersicon esculentum Mill.) varieties commonly grown by tomato farmers in Tanzania were evaluated for resistance to bacterial speck (Pseudomonas syringae pv. tomato) and bacterial spot (Xanthomonas vesicatoria) diseases, along with five introductions under screenhouse and field conditions. The four tomato varieties were Cal J, Moneymaker, Tanya and Roma VF. Seeds of the tomato varieties were purchased from seed vendors in the open market. The introductions that were included in the study were Bravo, Taxman, Stampede (from Sakata-Mayford Seeds (Pty) Ltd, South Africa), Torquay and BSS436 (from Bejo Zaden B.V., The Netherlands). In the screenhouse, results indicated that all the tomato varieties were susceptible to the two diseases, and suffered moderate to severe infection levels. The performance of the introductions against bacterial speck under screenhouse conditions was variable. All the introductions showed high levels of susceptibility to bacterial spot. Under field conditions, incidence of the diseases was high in all the locally available varieties tested, averaging 87% for bacterial spot and 82.3% for bacterial speck. The results of this study indicate that all the locally available tomato varieties included in the study were highly susceptible to bacterial speck and bacterial spot diseases.

Abstract

The paper describes the research on soft X-ray lasers with an active medium created using a gas puff target irradiated

with high-intensity laser pulses. The gas puff target in a form of an elongated gas sheet is produced by pulsed injection of

gas through a slit nozzle using a high-pressure electromagnetic valve. The method of generation of soft X-ray lasers using a

laser-irradiated gas puff target has been developed at the Institute of Optoelectronics. The collaborative experiments were

performed at various laser laboratories using high-intensity laser systems to irradiate the gas puff target and pump the X-ray

laser active medium. Results of these experiments are presented and discussed. Works aimed at increasing the efficiency of

X-ray lasers using a longitudinally irradiated gas puff target are also reviewed.

Abstract

The paper presents the result of investigations of aluminosilicate (low silica - 25 mol%) and phosphate optical fibres. The methods of glass preparation and their properties are showed. A set of physical measurements including: DTA, DSC, DL analysis, absorption spectroscopy, visible and infrared absorption edges and thermo-physical properties were determined. The stable glass compositions were doped with rare earth elements. Selected properties of obtained glasses are: high transmission, refractive index 1.53-1.68, high solubility of RE ions (up to 10 wt%). Double-crucible and rod-in-tube drawing techniques were applied to obtain aluminosilicate and phosphate double clad optical fibres doped with neodymium and ytterbium ions. Luminescence spectra of manufactured glasses and fibres are presented.

Abstract

The article corresponds to the 400th death annniversary of two famous European writers – Cervantes and Shakespeare – celebrated all around the world. The author tells about their lifes and takes into consideration the possiblility of their meeting together in Vailladolid. Besides, the author emphasizes on the qualities that are in common for Shakespeare’s and Cervantes’ works – among others the universality (their readers were both educated as well as simple), the ability to create symbolic figures and the application of colloquial language.
