Polyhydroxyalkanoate (PHA) is a new type of bio-polyester which expected to replace traditional petroleum-based plastics. The experiment was carried out based on anaerobic-microaerobic process. Firstly, the PHA accumulation capacity activated sludge under different pH conditions discussed, and then batch test nitrogen phosphorus limitation condition optimal pH. Moreover, content monomer nutrien...

Novel strategies that target the epidermal growth factor receptor (EGFR) have led to the clinical development of monoclonal antibodies, which treat metastatic colorectal cancer (mCRC) but only subgroups of patients with increased wild type KRAS and EGFR gene copy, respond to these agents. Furthermore, resistance to EGFR blockade inevitably occurred, making future therapy difficult. Novel bio-im...

Thalidomide is a sedative drug discovered at the end of 50s, it showed high anticancer activity so attempts were made to synthesize thalidomide analogs that had fewer side effects than parent compound. DPDQA higher activities thalidomide. Labeling with 99mTc using Na2S2O4 as reducing agent was performed. The dependence radiolabeling yield on concentrations and agent, pH reaction mixture, time, ...

The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). One of the reasons for unique properties of bio-nanocomposites is the difference in physics at nanoscale as compared to that at macroscale. Therefore, the effect of nanoscal...

Management of burn injury is an onerous clinical task since it requires continuous monitoring and extensive usage of specialized facilities. Despite rapid improvizations and investments in burn management, >30% of victims hospitalized each year face severe morbidity and mortality. Excessive loss of body fluids, accumulation of exudate, and the development of septic shock are reported to be the ...

The production of lactic acid from fossil fuel is now widely accepted as unsustainable due to depleting resources and the accumulation of environmentally hazardous chemicals. Cheap raw material is one of the key inputs to cost effective production of Lactic acid. This paper reviews current research in lactic acid fermentation processes, bio-residue availability in Ghana and potential utilizatio...
