Allogeneic Stem Cell Transplant Versus Tandem High-Dose Melphalan for Front-Line Treatment of Deletion 13q14 Myeloma – An Interim Analysis of the Ger…

2009

Abstract Abstract 51 Background Allogeneic stem cell transplantation (allo SCT), a treatment modality based on transfer of immunocompetent donor lymphocytes offers curative potential to subjects with a variety of hematological cancers. In multiple myeloma (MM), high-dose melphalan followed by autologous stem cell transplantation (auto SCT) is adopted as a standard of care. However, it remains palliative since virtually all patients (pts) relapse and renders allo SCT an option of interest. Deletion of chromosome 13q14 (13q-) in MM has been shown to negatively impact prognosis. Therefore, improvement of therapy for 13q- pts is highly desirable. Patients and methods A prospective two-arm multi…

Differential diurnal variations of anandamide and 2-arachidonoyl-glycerol levels in rat brain.

2004

The endogenous ligands of cannabinoid receptors, also known as endocannabinoids, have been implicated in many physiological and pathological processes of the central nervous system. Here we show that the levels of the two major endocannabinoids, anandamide and 2-arachidonoyl-glycerol (2-AG), in four areas of the rat brain, change dramatically between the light and dark phases of the day. While anandamide levels in the nucleus accumbens, pre-frontal cortex, striatum and hippocampus were significantly higher in the dark phase, the opposite was observed with 2-AG, whose levels were significantly higher during the light phase in all four regions. We found that the activity of the fatty acid ami…

Selective Stepwise Suzuki Cross-Coupling Reaction for the Modelling of Photosynthetic Donor−Acceptor Systems

2009

A Suzuki reaction performed as a selective stepwise substitution of two boryl groups on a diarylporphyrin precursor is reported for straightforward construction of a porphyrin trimer, modeling photosynthetic donor-acceptor systems.

Tackling Performance Challenges in Organic Photovoltaics: An Overview about Compatibilizers

2020

Organic Photovoltaics (OPVs) based on Bulk Heterojunction (BHJ) blends are a mature technology. Having started their intensive development two decades ago, their low cost, processability and flexibility rapidly funneled the interest of the scientific community, searching for new solutions to expand solar photovoltaics market and promote sustainable development. However, their robust implementation is hampered by some issues, concerning the choice of the donor/acceptor materials, the device thermal/photo-stability, and, last but not least, their morphology. Indeed, the morphological profile of BHJs has a strong impact over charge generation, collection, and recombination processes; control o…

Zvaguļu (Rhinanthus) izmantošana zālāju ekoloģiskajā atjaunošanā auglīgās augsnēs: sēklu kvalitātes un konkurences nozīme

2022

Ir zināms, ka mūsdienās viena no globālām problēmām ir klimata pārmaiņas, kura skar arī dažādas ekosistēmas un to stāvokli. Zālāju ekosistēmas ir diezgan jūtīgas pret apkārtējās vides izmaiņām, līdz ar to Latvijā ir novērojama dabisko zālāju sarukšanas tendence. Tādēļ, dabiskos zālājus ir nepieciešams saglābāt, apsaimniekot un atjaunot Latvijas mērogā. Ekoloģiskās atjaunošanas metodes mēdz būt visai dažādas, taču viena no jaunākajām, līdz šim Latvijā neaprobētām metodēm, ir zvaguļu pusparazītaugu ieviešanas metode, kura paredzēta zālājā esošo sugu konkurences samazināšanai, un maģistra darba mērķis ir noskaidrot sēklu kvalitātes un veģetācijas konkurences nozīmi zvaguļu izmantošanā zālāju e…

Effect of transition metals and homogeneous hydrogen producers in the hydrothermal liquefaction of sewage sludge

2022

Hydrothermal liquefaction (HTL) of sewage sludge (SS) was performed in the presence of metallic Zn, Fe and Ni to investigate their effect on the performances of the process in terms of product yields and quality. Experiments were performed in subcritical water at 350 ◦C for 10 min using each metal individually and in the presence of homogenous hydrogen producers like formic acid (FA) and KOH. Interesting results were obtained with Zn that when used alone or in the presence of KOH, increased the cumulative biocrude (BC) yields and resulted in energy recoveries (ER) higher than 100% with respect to initial energy content of the biomass, thus indicating that HTL of SS is globally endothermic. …

Science to Practice: Should Biopsy Be Performed in Potential Liver Donors When Unenhanced CT Shows an Unacceptable Degree of Steatosis for Transplant…

2006

Park et al (1) have demonstrated that unenhanced CT can accurately depict moderate to severe (ie, ≥30%) macrovesicular steatosis, thereby allowing avoidance of biopsy in potential living liver donors who have an unacceptable degree of steatosis for transplantation. Biopsy will still be needed in donors with macrovesicular steatosis of less than 30% at unenhanced CT to rule out occult chronic liver disease and more severe steatosis that is undetected at CT. © RSNA, 2006.

Le masserie delle Madonie: da simboli di abbandono a potenziali fattori di crescita di una "città a rete policentrica e diffusa"

2018

Le masserie delle Madonie: da simboli di abbandono a potenziali fattori di crescita di una “città a rete policentrica e diffusa” Il territorio montano delle Madonie, che ragionevolmente viene considerato una sub-regione della Sicilia Occidentale, si presenta come un territorio compatto dal punto di vista storico, culturale, economico ed architettonico al punto che, nel 2009, è nata una coalizione che ha portato alla formazione di una “città a rete formata da 28 comuni. Da sessant’anni a questa parte il comprensorio madonita vive un processo di erosione demografica in seguito a politiche di litoralizzazione dei centri di produzione, accentramento nei principali nuclei urbani dell’isola e all…

Sport commitment and adherence: A social-cognitive analysis. (Compromiso deportivo y adherencia: Un análisis cognitivo social).

2011

Abstract Statement of problem: This study aimed to analyse the ability of a model based on achievement motivation and self-determination theories to predict adherence to competitive sport. This model incorporated commitment as predictor of adherence. A prospective study was performed with a sample of 302 handball players aged between 14 and 18 years. Structural equation modelling gave support to the model proposed. It was verified the sequence of relationships between perceptions of coach-created mastery climate, psychological needs, self-determined motivation, commitment, and adherence. The major contribution of the study was to confirm a motivational model of adherence based on social-cog…
