Analysis of suicide attempts among children hospitalised in the Department of Paediatrics in Zabrze in 2010–2016
2018
Introduction: Despite the current decline in the number of suicides, they are the second most common cause of death among children and adolescents. At the end of the 20th century, suicides represented about 10% of all causes of death of people up to 18 years old, but currently they reach up to 20%. Over the years, the number of suicide attempts (SA) has also increased. Aim of the study: The aim of the study was to analyse the cases of hospitalisation of children in the Department of Paediatrics of the Independent Public Clinical Hospital No. 1 in Zabrze (DP IPCH1) due to a suicide attempt. Material and methods: Medical records of 87 patients hospitalised due to SA in the years 2010–2016 in …
How do health care services help and hinder recovery after a suicide attempt? A qualitative analysis of Finnish service user perspectives
2022
Background Suicide attempt survivors are at high risk of re-attempts and suicide death. Previous research has shown that service users’ experiences of post-attempt care are related to future treatment engagement and re-attempts. In-depth understanding of how current services meet service users’ needs in the period immediately following a suicide attempt is thus imperative for the development of more effective tertiary prevention practices in real-life health care systems. Method In this qualitative study, Finnish suicide attempt survivors’ experiences of and perspectives on mental health services were explored through a semi-structured interview. Participants were seven female and seven mal…
Titanocene Selenide Sulfides Revisited: Formation, Stabilities, and NMR Spectroscopic Properties
2019
[TiCp2S5] (phase A), [TiCp2Se5] (phase F), and five solid solutions of mixed titanocene selenide sulfides [TiCp2SexS5−x] (Cp = C5H5−) with the initial Se:S ranging from 1:4 to 4:1 (phases B–E) were prepared by reduction of elemental sulfur or selenium or their mixtures by lithium triethylhydridoborate in thf followed by the treatment with titanocene dichloride [TiCp2Cl2]. Their 77Se and 13C NMR spectra were recorded from the CS2 solution. The definite assignment of the 77Se NMR spectra was based on the PBE0/def2-TZVPP calculations of the 77Se chemical shifts and is supported by 13C NMR spectra of the samples. The following complexes in varying ratios were identified in the CS2 solutions of …
Tuning of Emission Wavelength of CaS:Eu by Addition of Oxygen Using Atomic Layer Deposition

The fine control at the atomic level allowed by ALD technology creates the perfect conditions for the inclusion of new cationic or anionic elements of the already-known materials. Consequently, novel material characteristics may arise with new functions for applications. This is especially relevant for inorganic luminescent materials where slight changes in the vicinity of the luminescent centers may originate new emission properties. Here, we studied the lumines…
Sulfidi- ja sulfaatti-ionien pitoisuuksien analysointi vesiliuoksessa

Sulfonamide moiety as "molecular chimera" in the design of new drugs.
2021
Background: The -SO2NH- group is of great significance in modern pharmaceutical use since, in sulfa-drugs, it is possible to introduce easily chemical modifications, and even small changes may lead to an improved version of an already existing drug. Objective: This paper aims to describe updated information in the sulfonamide field with a particular focus on new mechanisms of action, especially if discovered by employing computational approaches. Methods: Research articles that focused on the use of the sulfonamide moiety for the design, synthesis, and in vitro/in vivo tests of various diseases were collected from various search engines like PubMed, Science Direct, Google Scholar, and Scop…
1,2,6-Thiadiazine 1-Oxides: Unsaturated Three-Dimensional S,N-Heterocycles from Sulfonimidamides.
2020
Unprecedented three-dimensional 1,2,6-thiadiazine 1-oxides have been prepared by an aza-Michael-addition/cyclization/condensation reaction sequence starting from sulfonimidamides and propargyl ketones. The products have been further functionalized by standard cross-coupling reactions, selective bromination of the heterocyclic ring, and conversion into a β-hydroxy substituted derivative. A representative product was characterized by single-crystal X-ray structure analysis. peerReviewed

H2S fluxes from Mt. Etna, Stromboli and Vulcano (Italy) and implications for the global volcanic sulfur budget
2005
We present here new measurements of sulfur dioxide and hydrogen sulfide emissions from Vulcano, Etna, and Stromboli (Italy), made by direct sampling at vents and by filter pack and ultraviolet spectroscopy in downwind plumes. Measurements at the F0 and FA fumaroles on Vulcano yielded SO2/H2S molar ratios of 0.38 and 1.4, respectively, from which we estimate an H2S flux of 6 to 9 t · d 1 for the summit crater. For Mt. Etna and Stromboli, we found SO2/H2S molar ratios of 20 and 15, respectively, which combined with SO2 flux measurements, suggest H2S emission rates of 50 to 113 t · d 1 and 4 to 8 t · d 1, respectively. We observe that “source” and plume SO2/H2S ratios at Vulcano are similar, s…
