Urethroplasty with dorsal buccal mucosa graft. Is it still the method of choice in long term urethral stenosis?
2017
The aim of our work was to evaluate the long-term changes in symptoms (median 42 months) and to analyze data for any negative predictive factors for the application of the procedure, in patients who underwent to urethroplasty with dorsal buccal mucosa graft. During the period from 2010 to 2015 27 patients were examined. Than they underwent urethroplasty using dorsal buccal mucosa graft (graft of 4 x 2.5 cm). The evaluation of symptoms has been addressed through the application of the IPSS Quality of Life Questionnaire (International Prostatic Symptoms Score) and the evaluation of urinary flow has been carried out by a comparative analysis between the pre- and post-operative uroflowmetry. As…
Peroxisome proliferator-activated receptor γ ligands regulate neural stem cell proliferation and differentiation in vitro and in vivo.
2011
Peroxisome proliferator-activated receptor gamma (PPARγ) belongs to a family of ligand-activated nuclear receptors and its ligands are known to control many physiological and pathological situations. Its role in the central nervous system has been under intense analysis during the last years. Here we show a novel function for PPARγ in controlling stem cell expansion in the adult mammalian brain. Adult rats treated with pioglitazone, a specific ligand of PPARγ, had elevated numbers of proliferating progenitor cells in the subventricular zone and the rostral migratory stream. Electron microscopy analysis also showed important changes in the subventricular zone ultrastructure of pioglitazone-t…
Subventricular Zone-Derived Neuroblasts Migrate and Differentiate into Mature Neurons in the Post-Stroke Adult Striatum
2006
Recent studies have revealed that the adult mammalian brain has the capacity to regenerate some neurons after various insults. However, the precise mechanism of insult-induced neurogenesis has not been demonstrated. In the normal brain, GFAP-expressing cells in the subventricular zone (SVZ) of the lateral ventricles include a neurogenic cell population that gives rise to olfactory bulb neurons only. Herein, we report evidence that, after a stroke, these cells are capable of producing new neurons outside the olfactory bulbs. SVZ GFAP-expressing cells labeled by a cell-type-specific viral infection method were found to generate neuroblasts that migrated toward the injured striatum after middl…
Magnetic resonance imaging of the migration of neuronal precursors generated in the adult rodent brain
2006
Neural progenitor cells (NPCs) reside within the subventricular zone (SVZ) in rodents. These NPCs give rise to neural precursors in adults that migrate to the olfactory bulb (OB) along a well-defined pathway, the rostral migratory stream (RMS). Here we demonstrate that these NPCs can be labeled, in vivo, in adult rats with fluorescent, micron-sized iron oxide particles (MPIOs), and that magnetic resonance imaging (MRI) can detect migrating neural precursors carrying MPIOs along the RMS to the OB. Immunohistochemistry and electron microscopy indicated that particles were inside GFAP(+) neural progenitor cells in the SVZ, migrating PSA-NCAM(+) and Doublecortin(+) neural precursors within the …
Penkules evaņģēliski luteriskās baznīcas vēsture
2016
Bakalaura darbā „Penkules evaņģēliski luteriskās baznīcas vēsture” tika pētīta baznīcas un tās draudzes vēsture laika posmā no baznīcas celšanas 1865.gada līdz mūsdienām. Darbā galvenokārt apskatīta baznīcas celšanas vēsture, tās mācītāju un draudzes darbība dažādos laika posmos. Darba gaitā secināts, ka Penkules ev. lut. baznīcas un draudzes dzīve bijusi notikumiem bagātīga, kā arī jāpiemin tas, ka par šo tēmu bija pieejams salīdzinoši maz informācijas daudzums, no kura bija jāizveido detalizēts apraksts par Penkules baznīcu un draudzi. Izveidotais darbs palīdzētu apzināt un saglabāt aizmirstos kultūras pieminekļus Latvijas teritorijā.

Traumatic Isolated Intramural Duodenal Hematoma Causing Intestinal Obstruction
2015
A 21-year-old man was admitted 36 hours after a blunt abdominal trauma occurred during a sporting competition. He complained of colic epigastric abdominal pain, nausea, and vomiting. He was hemodynamically stable; blood counts and metabolic panel were normal. Abdominal CT showed an intestinal obstruction caused by an 8 x 6 x 11 cm hematoma on the right lateral duodenal wall without signs of active bleeding (Figure 1). He underwent gastric decompression and started total parenteral nutrition and intravenous pump inhibitors. Esophagogastroduodenoscopy (EGD) performed 48 hours after the diagnosis showed an extrinsic compression by a bluish obstruction in the first part of the duodenum resembli…
Fauna Europaea: Hymenoptera - Apocrita (excl. Ichneumonoidea)
2015
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. Hymenoptera is one of the four largest orders of inse…
Disruption of Eph/ephrin signaling affects migration and proliferation in the adult subventricular zone.
2000
The subventricular zone (SVZ) of the lateral ventricles, the largest remaining germinal zone of the adult mammalian brain, contains an extensive network of neuroblasts migrating rostrally to the olfactory bulb. Little is known about the endogenous proliferation signals for SVZ neural stem cells or guidance cues along the migration pathway. Here we show that the receptor tyrosine kinases EphB1-3 and EphA4 and their transmembrane ligands, ephrins-B2/3, are expressed by cells of the SVZ. Electron microscopy revealed ephrin-B ligands associated with SVZ astrocytes, which function as stem cells in this germinal zone. A three-day infusion of the ectodomain of either EphB2 or ephrin-B2 into the la…
La revisione del palinsesto veronese delle Istituzioni di Gaio e le schede di Bluhme
2014
In the light of unpublished material this paper reconstructs the history of the deciphering of Gaius’ palimpsest of the Capitular Library of Verona (BCapVr, Cod. XV) by Friedrich Bluhme. It deals for the first time with other copies of Bluhme’s transcriptions preserved at the Bonn University Library (ULB, S 675f; ULB, S 1440) and with their relationship to the ones at the Berlin State Library – Prussian Cultural Heritage (SBB-PK, Ms. lat. fol. 308, K. 2, Beil. 2, Fasz. 1).
