circulating tumor cells (ctcs) recognition and characterization in the peripheral blood of patients with breast cancer have proven practical and predictive value in different studies. however, the clinical significance of ctcs enumeration and molecular characterization in thepersonalization of breast cancer diagnosis and treatment remains under the debate. a literature search in pubmed, web of ...
Introduction: Genetics, cellular and molecular medicines are cutting-edge sciences and technologies that play an important role in improving human health and quality of life. In addition, medical and biological sciences have clearly shown that the onset of diseases differs from person to person due to their different genetic profiles and variations in molecular basis. Therefore, it is feasible ...
We employed a whole body magnetic resonance imaging protocol to examine the influence of age, gender, body weight, and height on skeletal muscle (SM) mass and distribution in a large and heterogeneous sample of 468 men and women. Men had significantly (P < 0.001) more SM in comparison to women in both absolute terms (33.0 vs. 21.0 kg) and relative to body mass (38.4 vs. 30.6%). The gender diffe...
Almost 40 years ago, evidence from large studies of adult twins and their relatives suggested that between 30 and 60% of the variance in social and political attitudes could be explained by genetic influences. However, these findings have not been widely accepted or incorporated into the dominant paradigms that explain the etiology of political ideology. This has been attributed in part to meas...
The molecular weight of approximately 1,500-fold purified arginase from rat liver (specific activity = 19,500 pmoles of urea per min at 25’ per mg of protein nitrogen) was determined by the method of sedimentation equilibrium to be 118,000. The sedimentation velocity constant is 6.1 S, the diffusion coefficient 5.2 X 10U7 cm2 per sec. Alteration in pH, removal of Mn2+, and replacement of Mn2+ b...
The equine periodontal ligament (PDL) is a fibrous connective tissue that covers the intra-alveolar parts of the tooth and anchors it to the alveolar bone-it, therefore, provides a similar function to a tendinous structure. While several studies have considered the formation and structure of tendons, there is insufficient information particularly on the molecular composition of the PDL. Especia...
Congenital glioblastoma (cGBM) is an uncommon tumor of infancy with a reported variable but often poor cure rate, even with intensive therapy. Five patients with cGBMs, arising de novo and not in familial tumor predisposition kindreds, were studied for histological and biological features, using Affymetrix microarray. Tumors were large, often associated with hemorrhage, extended into the thalam...
Myxopapillary ependymoma (MEPN) generally can be cured by gross total surgical resection and usually manifest a favorable prognosis. However, surgery is less curative in tumors that are large, multifocal or extend outside the thecal sac. Late recurrences may occur, particularly in pediatric patients. The role of adjuvant therapy is unclear in the clinical management of recurrent tumors. Clinica...
BACKGROUND There are several clinical variants of severe difficult-to-treat asthma: asthma with persistent airflow limitation, brittle asthma, and fatal asthma; but the differences between the pathogenetic mechanisms underlying the disease heterogeneity are unknown. OBJECTIVES The aim was to evaluate the morphological and molecular characteristics of brittle asthma type I and asthma with pers...
