The relative quantification of these proteins by label free mass spectrometry was validated by immunological assays and correlated with their serum expression levels.

The prevalence of diabetes mellitus is increasing.

The mass spectrometry analysis revealed significant differences in protein expression in follicular adenoma versus papillary thyroid carcinoma that could help in early prognosis and adequate treatment decision. Cercetarea moleculară are un rol important în descifrarea mecanismelor unor boliîn introducerea unor noi metode de investigaţii și tratament si în identificarea subiecţilor cu risc crescut.

Purpose: to compare mWT and 6 MWT between them, but also with classical exercise stress testing on cycloergometer, by using amino-terminal pro-B-type natriuretic peptide values NT-proBNP before and after exercise.

Mă voi opri numai la 2 domenii importante și anume genetica si imagistica moleculara. Genetica moleculară a intrat progre- siv și definitiv în multe domenii ale medicinii. In cardiologie întâlnim cel mai frecvent afecţiuni monogenice și putem vorbi de 3 mari clase de modificări genetice ale proteinelor: modificări structurale, modificări electrice și modificări de reglare.

Modificări structurale întâlnite în cardiomiopatii, tezaurismoze, sindromul Marfan etc; modificări ale proteinelor ţesutului electric: sindromul QT lung. Să luăm un exemplu. Cardiomiopatia hipertrofică este produsă de modificări ale genelor proteinelor sarcometrie, din care 3 sunt mai S4 Journal of Translational Medicine and Research 20 Supplement IIimportante cu o heterogenitate intra genică f.

Determinarea genetică este recomandată la probanţi, pentru a afla ce mutaţie este prezentăşi la rudele de gr. I pentru a afla care dintre acestia vor face boala. La început, în urmă cu ani,entuziasmul era foarte mare, vom afla cine produce boala și mai ales care din descendenţi va face boala.

Ulterior am constatat că nu putem preveni bola şi nici nu colorectal cancer biomarkers where are we now lua decizii terapeutice dacăștim modificarea genetică. Cu totul altă situaţie este cu Boala Fabri unde s-a descoperit enzima ce blochează depozitarea de colorectal cancer biomarkers where are we now în lizozomii celulelor mio- cardice, renale, piele.

Astfel impactul clinic al cercetării genetice în cardiologie este mult sub speranţele noastre privind prevenirea şi tratamentul unor boli. Exclud impactul asupra cunoasterii.

Imagistica moleculară se adaugă imagisticii structurale.

Aduce date noi din interiorul celulelor vii, in timp real, invizibile cu alte metode; implicate in diverse procese patologice. Daca mă refer numai la ateroscleroza: avem multe neinpliniri privnd prevenirea apariţiei plăcii de aterom, nu ştim prea bine cum,dece şi mai ales când se fisurează placa de aterom.

Ciuperci la borcan jamila destul de bine la tratamentul plăcii fisurate infarctul miocardic si prevenirea unui nou episode acut.

Ne intrebăm dacă imaginile moleculare pot modifica atitudinea medicului şi a bolnavului. Datele publicate până în prezent sunt încurajatore privind rolul efortului fizic,al statinelor si IECA. Ştim bine astazi rolul inflamatiei în afecţiunile cardiovasculare dar nu avem încă un tratament eficient al inflamaţiei,iar spernţele sunt mici.

Cercetarea medicală necesită costuri imense. In SUA se cheltuiesc 30 miliarde colorectal cancer biomarkers where are we now pentru cercetarea medicala. Ne punem uneori intrebarea daca cercetarea medicală se face pentru ingrijirea mai buna a bolnavilor sau pentru business?

Am aici în vedere tratamentul hipertensiunii arteriale,dar nu numai. Tehnologia actualatotusi departe de scanerul Dr. Early detec- tion of pancreatic cancer could decreases the mortality caused by this disease. The main focus is deciphering the molecular biology of this tumor type, in order to identify new factors related to pancreatic oncogenesis.

However, nuclear β-catenin protein accumulation has been correlated with late stages of tumor progression and metastasis A major role in genes regulation is epigenetic modification, especially DNA methylation. Identification of genes which undergo cancer-specific methylation changes and correlation of these data with tumor stage, progression, and long-term prognosis colorectal cancer biomarkers where are we now becoming increasingly common.

Another key factor for β-catenin gene regulation is ERBB2 which is over expressed in several cancer types. The aim of this study was to identify the factors involved in β-catenin gene expression deregulation in pancreas oncogenesis.

We found a decreasing methylation pattern of β-catenin promoter gene related to the disease stage. Fold change expression for β-catenin was between 0. These results sustain the increased β-catenin gene expression trough epigenetic alterations demethylation of gene promoter and the increasing of Colorectal cancer biomarkers where are we now gene expression, β-catenin regulatory factor.

Therefore, these factors may represent a trigger for pancreatic oncogenesis process. Urmare a acestui proces, celulele sistemului imunitar de exemplu, monocitele sunt atrase şi participa la transmigrarea celulelor tumorale printre CE si la formarea metastazelor. Datorita implicarii chemokinelor în metastazarea cancerelor de diferite origini, intervenţia terapeutica asupra sistemului de chemokine deschide noi oportunitati în tratamentul unor tipuri de cancer şi prevenirea metastazarii.

Scopul acestui studiu a fost de a testa daca directionarea liposomilor tinta-senzitivi TSL care transporta inhibitori ai receptorilor chemokinici si ii elibereaza specific la situsuri cu endoteliu activat reduc metastazarea celulelor tumorale.

Rezultatele au aratat ca in vitro, Vp-TSL-Tj se leagă specific de suprafata CE activate unde elibereaza compusul incorporat; acesta determina reducerea transmigrarii monocitelor si a celulelor tumorale prin endoteliul activat. Interesant si incurajator, doua administrari de liposomi Vp-TSL-Tj in soareci cu o ora inainte si la 16 ore dupa injectarea celulor tumorale a determinat o scadere semnificativa a metastazelor in plaman la 28 colorectal cancer biomarkers where are we now zile de la injectarea celulelor tumorale.

Aceste rezultate sunt o prima dovada ca nanocarausii care transporta și eliberează inhibitori de chemokine CCR2 la situsurile vasculare cu endoteliu activat reduc metastaza celulelor tumorale.

The disease is preventable by a live attenuated vaccine, that provides lifelong immunity in most recipients. A national measles vaccination program was implemented in Romania in an initiative of academician Nicolae Cajal.

Vaccination was conducted with an indigenous S6 Journal of Translational Medicine and Research 20 Supplement IImonovalent measles-containing vaccine Schwarz strain produced colorectal cancer biomarkers where are we now Cantacuzino Institute.

Nevertheless, during the last decade,Romania experienced at least two important measles outbreaks. The first one started in December and lasted until early More than 9, cases were detected, frequently in non-immunised patients belonging to the Roma ethnic group.

The second major epidemic episode occurred duringsimultaneously with a rubella epidemic in In contrast to other vaccine - preventable diseases, most cases of measles reflect a failure to receive vaccination. Failure to introduce appropriate infection-control measures,as well as the potential for and transborder viral transmission are alternative explanations for the extenssion of the transmission chain.

Enteroendocrine cells in the gut produce hormones that play essential roles in the regulation of food intake, energy expenditure and glucose homeostasis. Analogues of the gut hormone glucagon-like peptide-1 GLP-1 are widely used for the treatment of T2DM, and are under development for the treatment of obesity.

Recent findings, showing that many cases of T2DM resolve after gastric bypass surgery, have triggered a global interest in the gut endocrine system, and whether it could be harnessed for the treatment of diabetes and obesity. A body of evidence supports the idea that gut microbiota influence peripheral metabolism, and it is hypothesised that the underlying pathway includes modulation of the enteroendocrine cells with which they come into contact.

The types of enteroendocrine cells vary along the length of the intestinal tract. The colon contains the highest density of enteroendocrine L cells together with most of the gut bacteria. Here, we reveal that indole, a metabolite produced from the dissimilation of tryptophan, is able to modulate the secretion of GLP-1 from immortalized and primary mouse colonic Lcells and we reveal the molecular mechanism behind this modulation [1].
