<p>Clinical Evaluation of Everolimus in the Treatment of Neuroendocrine Tumors of the Lung: Patient Selection and Special Considerations. A Sys…
2020
Abstract Neuroendocrine tumors (NETs) of the lung are well-differentiated neuroendocrine neoplasms (NENs) with a heterogeneous clinical behaviour. Unlike gastroenteropancreatic NENs where therapeutic armamentarium clearly increased over the last decade, everolimus represented the only clinical practical innovation for lung NET patients over the last years. Therefore, for lung NETs, a multidisciplinary discussion within a dedicated team remains critical for an adequate decision-making. Although the main regulatory authorities considered the everolimus-related evidence is enough to approve the drug in advanced lung NETs, several clinical features deserve to be discussed. In this review, we sy…
Use of a three-factor interpretive optimisation strategy in the development of an isocratic chromatographic procedure for the screening of diuretics …
2000
Screening of diuretics in urine is feasible through direct injection of the samples into the chromatographic system and isocratic reversed-phase liquid chromatography (RPLC) with micellar-organic mobile phases of sodium dodecyl sulfate (SDS) and 1-propanol. The surfactant coverage of the chromatographic column makes the addition of organic competing amines less necessary than in conventional aqueous-organic RPLC to achieve well-shaped peaks. Also, the range of elution strengths of micellar mobile phases required to elute mixtures of hydrophobic and hydrophilic diuretics is smaller. This allows the isocratic separation of the diuretics within adequate analysis times. An interpretive methodol…
High-performance liquid chromatographic determination of diuretics in urine by micellar liquid chromatography.
1992
The use of micellar liquid chromatography for the determination of diuretics in urine by direct injection of the sample into the chromatographic system is discussed. The retention of the urine matrix at the beginning of the chromatograms was observed for different sodium dodecyl sulphate (SDS) mobile phases. The eluent strengths of a hybrid SDS-methanol micellar mobile phase for several diuretics were compared and related to the stationary phase/water partition coefficient with a purely micellar mobile phase. The urine band was appreciably narrower with a mobile phase of 0.05 M SDS-5% methanol (v/v) at 50 degrees C (pH 6.9). With this mobile phase the determination of bendroflumethiazide an…
Diferenciācijas indukcijas izpēte pēc BRAF un mTOR inhibitoru apstrādes BRAF mutētās ādas melanomas šūnās
2022
Darba mērķis bija padziļināti izpētīt BRAF inhibīcijas un sekojoši kombinētās BRAF un mTOR inhiibīcijas ietkemi uz metastātiskās BRAF mutēās melanomas šūnu līnijas SKMel28 šūnu ciklu, dzīvotspēju un inducēto atgriezensiko epitelilālo diferenciāciju. Ar advancētām mikroskopijas un šūnu analīzes metodēm tika apskatīti šos procesus iespējami ietkmējošie mehānismi. BRAF inhibīcija ar Vemurafenib rezultējās melanomas šūnu epiteliālā diferenciācijā un G1 arestā. Kombinētā BRAF un mTOR inhibīcija šūnās pagarināja šūnu diferencētā fenotipa stadiju, kas norāda uz iespējamu PI3K ceļa iesaisti SKMel28 šūnu augšanas un proliferācijas procesos. Lai arī pēc kombinētās BRAF-mTOR inhibīcijas diferencētais …
Le réseau des mesures de Météo-France en Franche-Comté
2000
Au cours des tout derniers jours de décembre 1999, deux dépressions très creuses ont balayé la France d'ouest en est. Les tempêtes ont frappé la Franche-Comté de plein fouet. Des vents à plus de 150 km/h (le maximum fut de 151 km/h à Métabief dans le Doubs) ont été mesurés par endroit‑! Il est probable qu'une telle puissance n'avait jamais été atteinte sous nos contrées dites " tempérées ". Les dégâts ont été considérables : toits arrachés sur tout le territoire, lignes électriques et téléphoniques coupées, forêts dévastées (on parle de plus de 2 millions de m3 de bois abattus).
Translation of HTT mRNA with expanded CAG repeats is regulated by the MID1-PP2A protein complex.
2012
Expansion of CAG repeats is a common feature of various neurodegenerative disorders, including Huntington's disease. Here we show that expanded CAG repeats bind to a translation regulatory protein complex containing MID1, protein phosphatase 2A and 40S ribosomal S6 kinase. Binding of the MID1-protein phosphatase 2A protein complex increases with CAG repeat size and stimulates translation of the CAG repeat expansion containing messenger RNA in a MID1-, protein phosphatase 2A- and mammalian target of rapamycin-dependent manner. Our data indicate that pathological CAG repeat expansions upregulate protein translation leading to an overproduction of aberrant protein and suggest that the MID1-com…
Decomposition Process of Carboxylate MOF HKUST-1 Unveiled at the Atomic Scale Level
2016
HKUST-1 is a metal-organic framework (MOF) which plays a significant role both in applicative and basic fields of research, thanks to its outstanding properties of adsorption and catalysis but also because it is a reference material for the study of many general properties of MOFs. Its metallic group comprises a pair of Cu2+ ions chelated by four carboxylate bridges, forming a structure known as paddle-wheel unit, which is the heart of the material. However, previous studies have well established that the paddle-wheel is incline to hydrolysis. In fact, the prolonged exposure of the material to moisture promotes the hydrolysis of Cu-O bonds in the paddle-wheels, so breaking the crystalline n…
Mežaudžu atjaunošana pēc kailcirtes Ziemeļvidzemes biosfēras rezervātā
2015
Maģistra darba ietvaros tiek apskatīta īpašuma piederības ietekme uz mežu atjaunošanas raksturu Latvijā. Pētījums aptver laika periodu no 1990. gada, kad sākas meža īpašuma piederību diversifikācija, līdz 2014. gadam. Šajā laikā valsti izveidojas 3 galvenie mežu īpašuma piederības veidi, kas iekļauj sevī valsts mežus, privātos mežus un Rīgas pašvaldības mežus. Pētījums sniedz skaidrojumu par meža atjaunošanas procesa īpatnībām katrā no šiem īpašuma piederības veidiem. Darbā tiek sniegta atbilde uz jautājumu par to, kuros īpašuma piederības veidos tiek nodrošināta optimālākā meža apsaimniekošana no ekonomiskā un ekoloģiskā skata punktiem. Darbs balstās uz autora ievākto informāciju par audžu…
Atherosclerosis: risk assessment and the role of aiming for optimal glycaemic control in young patients with type 1 diabetes
2023
Wprowadzenie: Dzieci z cukrzycą typu 1 (type 1 diabetes mellitus – DM1) mają w porównaniu ze zdrowymi rówieśnikami podwyższone ryzyko rozwoju zaawansowanej miażdżycy oraz choroby sercowo-naczyniowej (cardiovascular disease – CVD), a niedostateczna kontrola glikemii jest najważniejszym modyfikowalnym czynnikiem ryzyka CVD w DM1. Aktualne metody oceny kontroli glikemii to ocena hemoglobiny glikowanej (HbA1c), samokontrola glikemii za pomocą glukometru (SMBG), a także stosowanie systemów ciągłego monitorowania glukozy (CGM). Do pośredniej oceny ryzyka rozwoju CVD mogą służyć badania rozszerzenia tętnicy w odpowiedzi na niedokrwienie (flow-mediated dilatation – FMD) i prędkości fali tętna (PWV)…
