This study is the first report of preparation hydroxyethyl starch (HES) hydrogels rapidly crosslinked with divinyl sulfone in a single step and pot. To develop physical chemical features hydrogels, Graphene oxide (GO) nanoparticles were combined HES. In addition to swelling studies, structural characterization samples was conducted scanning electron microscope (SEM) transmission (TEM), Fourier ...

Species form the fundamental units of analysis in many areas of biology and, therefore, rigorous delimitation of this unit is important to a broad array of researchers. Recently, many new empirical methods have been proposed to delimit species in nature, and a large literature exists on the theoretical merit and superiority of each method. However, few empirical studies actually compare the res...

BACKGROUND Tuberculosis (TB) continues to be an important health problem, in many cases the Hospital Emergency Services (HES) are the first contact of the patients with the sanitary system, there is not known the impact of this disease in the above mentioned services. The objectives of this study are to know the importance of TB in HES and to describe hospital discharges (MBDS) with TB diagnosi...

UNLABELLED Hypovolemic patients with impairment of the blood-brain barrier may receive IV hydroxyethyl starch (HES) to stabilize cardiovascular function and to increase cerebral perfusion pressure. It is not known whether HES can penetrate into the cerebrospinal fluid (CSF) under those conditions. We investigated plasma and CSF levels of HES after IV infusion in patients with suspected disturba...

We have cloned genes related to hairy and Enhancer of split (hes) from glossiphoniid leeches, Helobdella robusta and Theromyzon rude. In leech, segments arise sequentially in anteroposterior progression from a posterior growth zone that consists of five bilaterally paired embryonic stem cells called teloblasts. Each teloblast gives rise to segmental founder cells (primary blast cells) that cont...

We study properties of semi-Eberlein compacta related to inverse limits. concentrate our investigation on an interesting subclass small whose elements are obtained as limits bonding maps semi-open retractions.

BACKGROUND Hydroxyethyl starch (HES) solutions may cause acute kidney injury (AKI) in humans. OBJECTIVE To compare AKI grades in 94 dogs exposed and 90 dogs that were unexposed to 6% HES-130/0.4. ANIMALS Dogs receiving 6% HES-130/0.4 (HES cohort) or crystalloids (unexposed cohort) between 2013 and 2015. METHODS Historical cohort study. Diagnosis, total cumulative dose and total mL/kg of H...

BACKGROUND Cardiomyocytes derived from human embryonic stem (hES) cells could be useful in restoring heart function after myocardial infarction or in heart failure. Here, we induced cardiomyocyte differentiation of hES cells by a novel method and compared their electrophysiological properties and coupling with those of primary human fetal cardiomyocytes. METHODS AND RESULTS hES cells were coc...
