Terpolymers of poly (Lysine-co-N, N-Bis (acryloyl) cystamine-co-β-Phenethylamine) (PLBP) were synthesized in one-pot by Michael addition terpolymerization. The terpolymers self-assembled into nano-sized spherical micelles (84-123nm) with narrow distributions. The surface charge of the nanomicelles (NMs) was depended on solution's pH and showed negative values under physiological conditions (pH7.4), which was beneficial for long circulation without non-specific protein adsorption. Doxorubicin (DOX) was effectively loaded into the NMs for controlled release...

Various classes of biodegradable polymers have been explored towards finding alternates for the existing treatments for bone disorders. In this framework, two families of polyesters using an array of crosslinkers were synthesized. One was based on galactiol/adipic acid and the other based on galactitol/dodecanedioic acid. The structures of the polymers were confirmed by FTIR and further confirmed by (1)H NMR. DSC showed that the polymers were amorphous and the glass transition temperature increased with increase in crosslinking...

Transition metal-containing proteins and enzymes are critical for the maintenance of cellular function and metal-based (metallo)drugs are commonly used for the treatment of many diseases, such as cancer. Detection and characterisation of metallodrug targets is crucial for improving drug-design and therapeutic efficacy. Due to the unique isotopic ratios of many metal species, and the complexity of proteomic samples, standard MS data analysis of these species is unsuitable for accurate assignment. Herein a new method for differentiating metal-containing species within complex LCMS data is presented based upon the Smart Numerical Annotation Procedure (SNAP)...

BACKGROUND: Children and adolescents with Juvenile Idiopathic Arthritis (JIA) typically have reduced physical activity level and impaired aerobic and anaerobic exercise capacity when compared to their non-JIA counterparts. Low intensity exercise regimens appear to be safe in children with JIA and may results in improvements in overall physical function. Poor adherence to paediatric rheumatology treatment may lead to negative clinical outcomes and possibly increased disease activity. This includes symptoms such as pain, fatigue, quality of life, longer term outcomes including joint damage, as well as increase of healthcare associated costs...

A facile, efficient and versatile approach is presented to synthesize pH-responsive nanocapsules (~120 nm) by combining the advantages of metal-organic frameworks (MOFs) and metal-organic thin films. The ZIF-8 nanoparticles are used as templates on which a thin film coating of Iron(III)-catechol complexes is derived from the coordination between dopamine-modified alginate (AlgDA) and Iron(III) ions. After the templates removal, nanocapsules with a pH-responsive wall are obtained. Doxorubicin (Dox), a typical anticancer drug, is first immobilized in ZIF-8 frameworks through coprecipitation and then encapsulated in nanocapsules after the removal of ZIF-8...

Antibiotic resistance is a worldwide public health problem (Bush et al. in Nat Rev Microbiol 9:894-896, 2011). The lack of effective therapies against resistant bacteria globally leads to prolonged treatments, increased mortality, and inflating health care costs (Oz et al. in Mol Biol Evol 31:2387-2401, 2014; Martinez in Science 321:365-367, 2008; Lipsitch et al. in Proc Natl Acad Sci USA 97:1938-1943, 2000; Taubes in Science 321:356-361, 2008; Laxminarayan et al. in Lancet, 2016; Laxminarayan et al. in Lancet Infect Dis 13:1057-1098, 2013)...
