Association of child maltreatment subtypes and long-term physical health in a German representative sample
2018
ABSTRACT Background: Child maltreatment is a major public problem, associated with enormous consequences on the individual and socioeconomic level. Studies show a clear impact of child maltreatment on long-term physical health. However, there is a lack of analyses comprising a wide variety of subtypes of maltreatment and addressing cumulative effects of different maltreatment subtypes experienced during childhood on physical health. Objective: The objective of this analysis was to assess the association of different subtypes and the intensity of child maltreatment with long-term physical health outcomes. Methods: In a cross-sectional observational approach, a representative sample of the Ge…

Mucocutaneous diseases with manifestations in the head and neck region: 24 years of experience in a Dermatology service
2023
This study aimed to evaluate the clinicopathological features of mucocutaneous diseases with manifestation in the head and neck region. A retrospective analysis of a dermatology reference center database was carried out. Over 24 years. Clinicopathological data were collected from medical records and the data was analyzed by descriptive statistics. A total of 11.538 medical records were analyzed, being 152 cases of mucocutaneous diseases with manifestations in the head and neck region. Cutaneous lupus erythematosus was the most prevalent diagnosis (66.4%). Face (44.1%), females (79.6%), and patients with 45 years mean age were the most common features. In the oral cavity, the most affected r…
Ķīmisko elementu izmaiņas pēc apmežošanās ar parasto egli (PICEA ABIES(L.)KARST) bijušajās lauksaimniecības zemēs
2017
Pamestas un aizaugošas lauksaimniecības zemes ir mūsdienu Latvijas ainavas būtiska sastāvdaļa. Latvijā šī tendence parādījās pēc 1989.gada, kad notika pāreja no centralizētas jeb plānveida ekonomikas uz tirgus. Sociālekonomiskās un politiskās pārmaiņas negatīvi ietekmēja lauksaimniecību, padarot to par ekonomiski neizdevīgu nozari, tāpēc cilvēki pameta lauku teritorijas, lai pārceltos uz dzīvi pilsētās. Bakalaura darba ietvaros ir veikts pētījums par augsnes ķīmisko īpašību izmaiņām, kuras notikušas saistībā ar lauksaimniecībā izmantojamo zemju apmežošanos teritorijās, kur augsnes cilmiezi veido glacigēnie morēnas nogulumi. Apmežošanās procesa ietekme uz augsnes īpašībām ir aktuāla tēma Lat…
A parasitoloxia e a doutrina do contáxio animado: a helmintiase e a sarna na España do século XIX
1990
Les explicacions parasitològiques del contagi eren tant teòriques com observacionals. La triquinosi, la sarna i la helmintiasi van ser exemples primerencs que van demostrar un contagi viu. A principis del segle XIX, en la medicina espanyola, igual que en la medicina europea, es rebutjava el contagi animat excepte en el cas d'alguns paràsits animals com la sarna. En uns altres, com en la helmintiasi intestinal, s'acceptava el seu origen viu, però no la seua contagiositat, i es defensava la seua generació espontània fins a ben entrat el segle XIX. En el “Diccionari de Ciències Mèdiques”, l'estudi dels cucs és quasi exclusivament morfològic i es defensa com a causa de la seua presència en l'ho…
Sentirsi Genitori. Esperienze di maltrattamento nell'infanzia e pratiche di parenting in età adulta
Políticas sanitarias locales puestas a prueba: consultores, expertos, misiones internacionales y poliomielitis en España, 1950-1975 = Local health po…

Aquest treball analitza les missions d'experts d'organismes sanitaris internacionals a Espanya destinades a informar sobre la situació, les activitats realitzades i les intervencions necessàries en la lluita contra la discapacitat física dels xiquets. El Pla Espanya-23 va ser l'instrument utilitzat per l'OMS i altres agències per a posar en marxa el procés de canvi en un país en transformació durant la llarga etapa de vigència de la dictadura franquista. El treball utilitza com a fonts informes inèdits d'experts de l'OMS, que van ser resultat de visites realitzades al país entre 1950 i 1975. L'abordatge metodològic va consistir en una anàlisi del discurs que es troba en les fonts i la seua …
Transition metal complexes of tetradentate and bidentate Schiff bases as catalysts for ethylene polymerization: Effect of transition metal and cocata…
2009
This article compares catalytic performance of ethylene polymerization in similar polymerization conditions of transition metal complexes having two ligands [O,N] (phenoxy-imine) and having one tetradentate ligand [O,N,N,O] (salphen or salen). It is shown that the activity of both complex types as well as the product properties depend in the same way on the type of central metal in the complex and on the cocatalyst used. Although the type of ligand has some effect on the catalyst activity, yet it does not control the properties of the obtained products. The vanadium and zirconium complexes, irrespective of the cocatalyst used, yield linear polyethylene with high molecular weight (a few hund…
Vanadium complex with tetradentate [O,N,N,O] ligand supported on magnesium type carrier for ethylene homopolymerization and copolymerization
2010
Immobilization of 1,2‐cyclohexylenebis(5‐chlorosalicylideneiminato)vanadium dichloride on the magnesium support obtained in the reaction of MgCl2·3.4EtOH with Et2AlCl gives a highly active precursor for ethylene homopolymerization and its copolymerization with 1‐octene. This catalyst exhibits the highest activity in conjunction with MAO, but it is also highly active with AlMe3 as a cocatalyst. On the other hand, when combined with chlorinated alkylaluminum compounds, Et2AlCl and EtAlCl2, it gives traces of polyethylene. Moreover, its catalytic activity is strongly affected by the reaction temperature: it increased with rising polymerization temperature from 20 °C to 60 °C. The kinetic curve…
Ethylene polymerization with FI complexes having novel phenoxy‐imine ligands: Effect of metal type and complex immobilization
2011
A series of bis(phenoxy‐imine) vanadium and zirconium complexes with different types of R3 substituents at the nitrogen atom, where R3 = phenyl, naphthyl, or anthryl, was synthesized and investigated in ethylene polymerization. Moreover, the catalytic performance was verified for three supported catalysts, which had been obtained by immobilization of bis[N‐(salicylidene)‐1‐naphthylaminato]M(IV) dichloride complexes (M = V, Zr, or Ti) on the magnesium carrier MgCl2(THF)2/Et2AlCl. Catalytic performance of both supported and homogeneous catalysts was verified in conjunction with methylaluminoxane (MAO) or with alkylaluminium compounds (EtnAlCl3−n, n = 1–3). The activity of FI vanadium and zirc…
