Frequency-specific network activity predicts bradykinesia severity in Parkinson’s disease

2021

Highlights • Parallel subnetworks are affected in bradykinesia. • The primary motor and the premotor cortex are common nodes with task-specificity. • Beta activity decreases, gamma activity increases with improvement of bradykinesia. • Subthalamic stimulation reduces beta, increases gamma power in ipsilateral cortex. • Subnetworks act with frequency-specific oscillations.

La psicoterapia come laboratorio di metafore. Una prospettiva integrata di psicoterapia cognitivista e musicoterapia

2010

Il trend attuale in campo epistemologico e teorico-concettuale aspira alla scoperta di linguaggi condivisi e condivisibili tra i diversi approcci psicoterapeutici. Spesso è accaduto che all’avvicinamento tra tecniche a matrice diversa non seguisse un accurato studio teorico orientato a definire e fornire un substrato concettuale a ciò che si era già rivelato utile nella pratica. Di contro, gli sviluppi delle neuroscienze hanno fornito oggi elementi molto utili alla comprensione di ciò che accade nelle stanze di psicoterapia; a partire dalla contestazione di antiche acquisizioni, date per consolidate, come la presunta incapacità della cellula neuronale di riprodursi e arborizzare in età adul…

Miega artērijas audzēju ķirurģiska ārstēšana Latvijā no 2010. līdz 2015.gadam

2016

Ievads: Miega artēriju audzēji (MAA) ir reti, lēni augoši un labi apasiņoti neiroendokrīni veidojumi, kuru izcelsme ir miega artērijas bifurkācijas līmenī esošās paraganglionārās šūnas. Mērķis: Pētījuma mērķis bija izpētīt MAA pacientus Latvijā pēdējo piecu gadu laikā, veicot demogrāfisku, kā arī ārstēšanās iznākumu analīzi. Materiāli un metodes: Tika veikta retrospektīva analīze, caurskatot pacientu slimības vēstures no 2010. līdz 2015. gadam Paula Stradiņa Klīniskās Universitātes slimnīcā, kurā esošais asinsvadu ķirurģijas centrs ir vadošais Latvijā, kurā ārstē MAA. Pētījuma ietvaros pacienti tika arī uzaicināti uz duplex ultrasonogrāfiju apsekošanai. Rezultāti: Kopumā 10 pacientiem tika …

Study on difficulties and misconceptions with modern type systems

2014

Functional programming is often presented as an advantageous programming paradigm by its advocates, but many students and teachers consider it to be hard to learn. One particular hurdle in learning functional programming is mastering the modern type systems employed in these languages. In this article, we identify student difficulties with means of multiple choice questions embedded into the on-line materials of an introductory functional programming course. The most prevalent misconceptions were confusing with parametric polymorphism with subtyping, the assigning too much meaning to variables names, and confounding general language patterns with special cases.

Use of monitoring intraoperative parathyroid hormone during parathyroidectomy in patients on waiting list for renal transplantation.

2007

This report describes the use of intraoperative parathyroid hormone (ioPTH) assay during parathyroidectomy for patients with secondary hyperparathyroidism on the waiting list for renal transplantation. The levels of ioPTH were determined among waiting list patients undergoing subtotal parathyroidectomy and tertiary hyperparathyroidism patients undergoing procedures. The levels of ioPTH were significantly reduced at 10 minutes by 59.7,3% among with secondary hyperparathyroidism and 68.9% among tertiary hyperparathyroidism. A 15 minutes it was 85% in secondary hyperparathyroidism and 89.7% in tertiary hyperparathyroidism. A decrement of 50% in basal values at 10 minutes and 85% decrement or m…

Reoperation for persistent or recurrent secondary hyperparathyroidism. Surgical treatment of renal hyperparathyroidism

2017

Background: Secondary hyperparathyroidism is a common acquired disorder seen in chronic renal failure. Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. When medical treatment fails, subtotal and total parathyroidectomy with autotransplantation are the standard procedures, although both are associated with high recurrence rates. Methods and Results: 4 patients experienced persistence and 9 relapse. The first 4 were subjected to reoperation after 6 months for the persistence of symptoms due to the finding of a supernumerary adenomatous gland while the remaining patients at the reoperation showed in 5 cases 2 more glands in over thymic position, a…

Nitric oxide modulation of the basal ganglia circuitry: therapeutic implication for Parkinson's disease and other motor disorders.

2011

Several recent studies have emphasized a crucial role for the nitrergic system in movement control and the pathophysiology of the basal ganglia (BG). These observations are supported by anatomical evidence demonstrating the presence of nitric oxide synthase (NOS) in all the basal ganglia nuclei. In fact, nitrergic terminals have been reported to make synaptic contacts with both substantia nigra dopamine-containing neurons and their terminal areas such as the striatum, the globus pallidus and the subthalamus. These brain areas contain a high expression of nitric oxide (NO)-producing neurons, with the striatum having the greatest number, together with important NO afferent input. In this pape…

Study of Beauty Hadron Decays into Pairs of Charm Hadrons

2014

First observations of the decays Λ[0 over b] → Λ[+ over c]D[− over (s)] are reported using data corresponding to an integrated luminosity of 3  fb[superscript −1] collected at 7 and 8 TeV center-of-mass energies in proton-proton collisions with the LHCb detector. In addition, the most precise measurement of the branching fraction B(B[0 over s] → D[superscript +]D[− over s]) is made and a search is performed for the decays B[0 over (s)] → Λ[+ over c]Λ[− over c]. The results obtained are B(Λ[0 over b] → Λ[+ over c]D[superscript −])/B(Λ[0 over b] → Λ[+ over c]D[− over s]) = 0.042 ± 0.003(stat) ± 0.003(syst), ⎡⎣B(Λ[0 over b] → Λ[+ over c]D[− over s]) over B([¯ over B[superscript 0] → D[superscr…
