Useful Evidence by Post-Mortem CT and Stereomicroscopy in Bone Injury: A Case Series from Forensic Practice

2023

The investigation of bone injuries is an essential topic in forensics. We sometimes have to deal with charred or dismembered human remains that have lost soft tissue, making it difficult to diagnose the mechanisms of injury that led to death. Our contribution aims to share with the scientific community how we approached two cases of very different bone injuries and the techniques used to differentiate relevant pathology findings of bone fragments. Two cases are analyzed from the case history of the forensic medicine institute of Palermo. PMCT made it possible to differentiate heat bone lesions from traumatic lesions. The stereomicroscope was superior to PMCT in being able to better characte…

Multifokālo kontaktlēcu lietotāju redzes asums un stereoredze

2018

Bakalaura darbs uzrakstīts uz 37 lapaspusēm, satur 10 zīmējumus, 5 tabulas un 18 literatūras avotus. Darba mērķis ir novērtēt redzes asumu un stereoredzi tuvumā un tālumā pacientiem koriģētiem ar brillēm un multifokālajām kontaktlēcām. Mūsu pētījumi parādīja, ka tāluma binokulārais redzes asums visiem pacientiem ir labs – virs 0,95. Tuvuma redzes asums pacientiem koriģētiem ar brillēm ir labāks un pacienti dod priekšroku brillēm. Tuvuma stereoredze noteikta ar Titmusa mušas testu un Titmusa apļu testu pacientiem koriģētiem ar brillēm un kontaktlēcām bija laba. Tāluma stereoredzes parametriem mēs redzam atšķirību, ar brillēm stereoredze ir labāka, bet rezultātu atšķirība nav statistiski būti…

Diversity of Isomerization Patterns and Protolytic Forms in Aminocarbene PdII and PtII Complexes Formed upon Addition of N,N′-Diphenylguanidine to Me…

2017

Reaction of the palladium(II) and platinum(II) isocyanide complexes cis-[MCl2(CNR)2] [M = Pd, R = C6H3(2,6-Me2) (Xyl), 2-Cl-6-MeC6H3, cyclohexyl (Cy), t-Bu, C(Me)2CH2(Me)3 (1,1,3,3-tetramethylbuth-1-yl abbreviated as tmbu); M = Pt, R = Xyl, 2-Cl-6-MeC6H3, Cy, t-Bu, and tmbu] with N,N′-diphenylguanidine (DPG) leads to DPG-derived metal-bound deprotonated acyclic diaminocarbene (ADC) species. This reaction occurs via a two-step process, involving the initial coupling of the guanidine with one of the isocyanides and leading to deprotonated monocarbene monochelated species, while the next addition grants the deprotonated bis-carbene bis-chelated metal compounds. DPG behaves as nucleophile, depr…

Interaction of mushroom tyrosinase with aromatic amines, o-diamines and o-aminophenols

2004

3-Amino-L-tyrosine was found to be a substrate of mushroom tyrosinase, contrary to what had previously been reported in the literature. A series of amino derivatives of benzoic acid were tested as substrates and inhibitors of the enzyme. 3-Amino-4-hydroxybenzoic acid, 4-amino-3-hydroxybenzoic acid and 3,4-diaminobenzoic acid were oxidized by this enzyme, as previously reported for Neurospora crassa tyrosinase, but 4-aminobenzoic acid and 3-aminobenzoic acid were not. Interestingly, 3-amino-4-hydroxybenzoic acid was oxidized five times faster than 4-amino-3-hydroxybenzoic acid, confirming the importance of proton transfer from the hydroxyl group at C-4 position. All compounds inhibited the m…

Diskriminierung von Senioren – Fakten über und Wege für das würdige altern

2018

Obecne stulecie przedstawiane jest często jako wiek starzenia się. Nieproporcjonalne zwiększanie się grupy ludzi starych, do prawie jednej czwartej społeczeństwa niesie ze sobą nie tylko dumę z osiągnięć medycyny przedłużającej życie, lecz także negatywne trendy społeczne. Postępujące procesy, które zostały już określone jako „desolidaryzacja międzygeneracyjna”, znajdują swój wyraz także w bardzo negatywnych zjawiskach, wśród których na znaczenia nabiera dyskryminacja osób starszych. Bazujące na stereotypach i uprzedzeniach negatywne nastawienie do najstarszej części społeczeństwa budzi niepokój i domaga się poszukiwania dróg wyjścia. W niniejszym opracowaniu na podstawie analizy polskojęzy…

Instrumenttivalintojen syyt ja seuraukset puhallinsoittajilla

2014

Tutkimuksen tarkoituksena oli selvittää tekijöitä, joiden perusteella puhallinsoittajat ovat päätyneet soittamaan pääinstrumenttiaan. Aiempien tutkimusten perusteella useat eri tekijät ohjailevat instrumenttivalintaa, mutta tutkijoiden käsitykset eri soittimiin liitettyjen sukupuolistereotypioiden vaikutuksista ovat yhtenäisimpiä. Näin ollen ne saivat suurehkon painoarvon myös tässä tutkimuksessa. Lisäksi soitinvalinnan taustatekijöitä vertailtiin eri maantieteellisten alueiden näkökulmasta. Tutkimuksessa pyrittiin kartoittamaan myös suomalaisen puhallinmusiikkiharrastuksen ja -ammatin yksityiskohtia erityisesti yksilön näkökulmasta. Tarkastelun alla olivat esimerki…

(E)-1-(Pyridin-4-yl)propan-1-one oxime

2016

The asymmetric unit of the title compound, C8H10N2O, contains two crystallographically independent molecules of slightly different conformation, which are linkedviaan intermolecular O—H...N hydrogen bond. The dihedral angle between the pyridine ring and the oxime plane of moleculeA[2.09 (19)°] is smaller than in moleculeB[16.50 (18)°].

Poly[[tetramethanolbis[4-oxo-3-(pyridin-4-yl)-1-(2,4,6-trichlorophenyl)-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-olato]disodium]–diethyl ether–metha…

In the title compound, [Na2(C16H7Cl3N5O2)2(CH3OH)4]·C4H10O·2CH3OH, the central pyrazolo[3,4-d]pyrimidine system makes dihedral angles of 82.98 (7)° with the trichlorophenyl ring and 13.11 (15)° with the pyridine ring. The sodium ion has an octahedral environment, being coordinated by four methanol molecules and one O and one N atom of two different heterocyclic ring systems.
