The first human embryonic stem cell (hESC) line was developed in the late nineties. hESCs are capable of proliferating indefinitely and differentiate into all the three embryonic germ layers. Further, the differentiation of hESC lines into neural precursor cells and neurons, astrocytes and oligodendrocytes showed their potential in treating several incurable neurological disorders such as spinal cord injury (SCI), cerebral palsy (CP), Parkinson's disease (PD). In this review, we will discuss the global scenario of research and therapeutic use of hESCs in the treatment of neurological disorders...

Synthetic cannabinoids have been prohibited due to abuse liability and toxicity. Four such synthetic cannabinoids, AM-2201, CP-47,497, JWH-122, and JWH-250, were tested for their capacity to produce CB1 receptor-mediated discriminative stimulus effects in two groups of rhesus monkeys. One group (n=4) discriminated ∆9-THC (0.1 mg/kg i.v.) and a second group (n=4) discriminated the cannabinoid antagonist rimonabant (1 mg/kg i.v.) while receiving 1 mg/kg/12 h of ∆9-THC. AM-2201, JWH-122, CP-47,497, JWH-250, and ∆9-THC increased ∆9-THC-lever responding...

Nonviral gene delivery systems are finding widespread use due to their safety, rapid and economical production, and ease of modification. In this work, series of N-alkyl-substituted linear polyethylenimine (CP) polymers have been synthesized, characterized, and investigated about how degree of substitution (hydrophobic-hydrophilic balance) (i.e. N-alkylation) influenced the transfection efficiency. Mobility shift assay demonstrated efficient binding of plasmid DNA (pDNA). Transfection efficiency and cytotoxicity of CP polymers were assessed in vitro, which revealed that all the formulations exhibited higher transfection activity than linear polyethylenimine (lPEI) and commercial transfection reagents, Lipofectamine and Superfect, with negligible toxicity (MTT assay)...

Bacterial cellulose membrane is a biomaterial with high value in the biomedical field. Many groups have been making efforts to promote chemical modifications of its structure and, consequently, add new characteristics. Recently, our group has developed a methodology to insert monoester succinic acid in bacterial cellulose membrane without disrupting the microfibril network and bind a protein on it. Considering the role of carbohydrates in the molecular recognition process in biological events, we continued these studies by inserting covalently multiples copies of aryl monosaccharide to bacterial cellulose succinylated and to study the in vitro tissue compatibility using fibroblasts...

A novel timolol voltammetric sensor based on the nano-sized molecularly imprinted polymer (nano-MIP)-modified carbon paste electrode was introduced. Timolol-imprinted polymers (MIP) were synthesized by the ultrasonic assisted suspension polymerization in silicon oil. The MIP nanoparticles were then embedded in a carbon paste (CP) electrode in order to prepare the nano-MIP-CP electrode. Timolol was extracted in the electrode for a definite time and then it was analyzed by square wave voltammetry, found to be an effective determination method...

Transglutaminase (TGase) has been implicated in maintaining the undifferentiated stage of hematopoietic stem cells (HSC) in the crayfish Pacifastacus leniusculus. TGase activity has been reported to be regulated by astakine1, an essential crayfish cytokine for inducing new hemocyte synthesis in hematopoietic tissue (HPT). Here, the role of astakine1 in TGase activity regulation and clotting protein (CP) cross-linking was characterized. A reduction in TGase activity was observed by the addition of purified astakine1 in vitro for both endogenous crayfish TGase and a commercial purified guinea pig liver TGase...

This study introduces activated carbon (AC) as an effective anode for microbial fuel cells (MFCs) using real industrial wastewater without treatment or addition of external microorganism mediators. Inexpensive activated carbon is introduced as a proper electrode alternative to carbon cloth and carbon paper materials, which are considered too expensive for the large-scale application of MFCs. AC has a porous interconnected structure with a high bio-available surface area. The large surface area, in addition to the high macro porosity, facilitates the high performance by reducing electron transfer resistance...

Wilmore C Webley, David L Hahn
Asthma is a chronic respiratory disease characterized by reversible airway obstruction and airway hyperresponsiveness to non-specific bronchoconstriction agonists as the primary underlying pathophysiology. The worldwide incidence of asthma has increased dramatically in the last 40 years. According to World Health Organization (WHO) estimates, over 300 million children and adults worldwide currently suffer from this incurable disease and 255,000 die from the disease each year. It is now well accepted that asthma is a heterogeneous syndrome and many clinical subtypes have been described...
