Nowadays, scientific findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. Furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. ⋯ In this review we searched in PubMed search engine by using following keywords; "Stem Cells", "Cell Tracking", "Stroke", "Stem Cell Transplantation", "Nanoparticles", and "Magnetic Resonance Imaging" as entry terms and based on the mentioned key words, the search period was set from 1976 to 2012. The main purpose of this article is describing various advantages of molecular and magnetic resonance imaging of stem cells, with focus on translation of stem cell research to clinical research.

Echocardiography is one of the diagnostic tools that can be applied at the bedside, along with avoiding transporting critically ill patients. This prospective observational study was designed to assess the clinical applicability of the transthoracic echocardiography (TTE) device by noncardiologist intensivists. ⋯ Transthoracic approach can provide useful information on cardiac anatomy and function in most ICU patients along with detecting severe previously unknown conditions in some patients.

Few investigation has focused on the patients with lupus nephritis (LN) and neuropsychiatric systemic lupus erythematosus (NPSLE). This study was aimed to investigate the clinical features, mortality, and the predictors for mortality of this group of patients. ⋯ Most of SLE patients with LN and new-onset NPSLE are in an active disease state. NP manifestation itself was the leading cause of death during hospitalization. Childhood-onset NPSLE, AKI and pneumonia might be predictors of mortality, whereas CYC treatment might improve the prognosis.

There is no published data on the association between serum biochemical and ultrasonographic markers and adverse pregnancy outcomes. Therefore, the aim of this study was to determine the factors associated with perinatal outcomes in singleton pregnancies using ultrasound and maternal serum markers during the first trimester in Panamanians. ⋯ Abnormal ultrasound markers are associated with adverse outcomes. Women with normal ultrasound and serum markers should be reassured of low risk of adverse pregnancy outcomes.

Cystatin C (Cys C) has been implicated as a prognostic marker in cardiovascular disease. The aim of this study was to evaluate the value of Cys C as a marker of acute kidney injury (AKI) in acute heart failure (AHF), the impact of Cys C and N-terminal probrain natriuretic peptides (NT-proBNP) on in-hospital and 12 months mortality were also investigated. ⋯ Cys C was not only a promising risk marker in patients hospitalized for AHF, but also an independent predictor of 12-month mortality. Combining tertiles of Cys C and NT-proBNP could be used to distinguish the mortality risk identification of patients with AHF. AKI was an independent predictor of in-hospital and 12-month mortality.
