Efficacy and safety of alpha lipoic acid-capped silver nanoparticles for oral applications.

Silver nanoparticles (AgNPs) are widely studied for their broad-spectrum antimicrobial effects, and can be utilised readily in biomaterials, however the cellular safety of specific AgNP formulations should be profiled prior to clinical usage. This study determined the cytotoxic effect of small sized (6 nm) alpha lipoic acid capped-AgNPs on human gingival fibroblasts (HGF), as compared to ionic silver and clinical antiseptics. The metabolic pathway was investigated to determine the cellular effects on HGF cells.

A Comparative Study of Fluorescence Assays in Screening for BRD4.

Fluorescence assay technologies are commonly used in high-throughput screening because of their sensitivity and ease of use. Different technologies have their characteristics and the rationale for choosing one over the other can differ between projects because of factors such as availability of reagents, assay performance, and cost. Another important factor to consider is the assay susceptibility to artifacts, which is almost as important as the ability of the assay to pick up active compounds.

Single-Domain Antibody-Functionalized pH-Responsive Amphiphilic Block Copolymer Nanoparticles for Epidermal Growth Factor Receptor Targeted Cancer Therapy.

Biocompatible antibody-nanoparticle conjugates have attracted interest as anticancer agents due to their potential to selectively target therapeutic agents at disease sites. However, new formulation and conjugation approaches are urgently needed to improve their uniformity for clinical applications. Here, a pH-responsive benzaldehyde-functionalized poly[oligo(ethylene glycol) methacrylate--formyl phenyl methacrylate]--poly[2-(diisopropyl)aminoethyl methacrylate] [P(OEGMA--pFPMA)--PDPA] block copolymer, prepared by reversible addition-fragmentation chain transfer polymerization, produced PEGylated nanoparticles (pH ∼ 7.

Chemokines as novel and versatile reagents for flow cytometry and cell sorting.

Cell therapy regimens are frequently compromised by low-efficiency cell homing to therapeutic niches. Improvements in this regard would enhance effectiveness of clinically applicable cell therapy. The major regulators of tissue-specific cellular migration are chemokines, and therefore selection of therapeutic cellular populations for appropriate chemokine receptor expression would enhance tissue-homing competence.

Occupational identity disruption after traumatic brain injury: an approach to occupational therapy evaluation and treatment.

People with traumatic brain injury (TBI) represent a significant population for occupational therapy practitioners. The long-term physical, cognitive, behavioral, and psychosocial symptoms of TBI can contribute to the experience of occupational identity disruption and affect participation outcomes in community living. Although occupational therapy scholars have studied the topic of identity, there appears to be a gap in the education and research literature regarding the topic of post-TBI occupational identity disruption.
