Organic waste residues can be hydrothermally treated to produce organic acid rich liquors. These hydrothermal liquors are a potential feedstock for polyhydroxyalkanoate (PHA) production. We investigated the effect of dissolved oxygen concentration and substrate feeding regimes on PHA accumulation and yield using two hydrothermal liquors derived from a mixture of primary and secondary municipal wastewater treatment sludge and food waste. The enriched culture accumulated a maximum of 41% PHA of cell dry weight within 7 h; which is among the highest reported for N and P rich hydrothermal liquors...

Microarray technology to isolate living cells using external fields is a facile way to do phenotypic analysis at the cellular level. We have used alternating current dielectrophoresis (AC-DEP) to drive the assembly of live pathogenic Salmonella typhi (S.typhi) and Escherichia coli (E.coli) bacteria into miniaturized single cell microarrays. The effects of voltage and frequency were optimized to identify the conditions for maximum cell capture which gave an entrapment efficiency of 90% in 60 min. The chip was used for calibration-free estimation of cellular loads in binary mixtures and further applied for rapid and enhanced testing of cell viability in the presence of drug via impedance spectroscopy...

Variable lymphocyte receptors B (VLRBs) are non-immunoglobulin components of the humoral immune system in jawless vertebrates including hagfish (Eptatretus burgeri) and lamprey (Petromyzon marinus). Hagfish VLRBs consist of leucine rich repeat (LRR) modules with a superhydrophobic C-terminal tail, the latter of which leads to extremely low expression levels in recombinant protein technology. Here, we present an artificially oligomerized VLRB (arVLRB) that conjugates via the C4bp oligomerization domain derived from human C4b-binding protein (hC4bp) rather than the superhydrophobic tail...

The biodegradability and ecological safety assessment of the previously isolated DDT-degrading bacterial strain Stenotrophomonas sp. DDT-1 were investigated in the DDT-contaminated soil under laboratory and field conditions. Under laboratory conditions, the degradation rates of fresh p,p'-DDT in soil were enhanced by 2.0-3.0-fold with the introduction of the strain DDT-1 compared to those of the control treatments. A similar enhancement in the dissipation of DDTs (p,p'-DDT, p,p'-DDE, p,p'-DDD, and o,p'-DDT) in the aged DDT-contaminated field plot soils resulted from the inoculation with this strain...

β-tricalcium phosphate (β-TCP) is well known as a resorbable bone repair material due to its inherent excellent biocompatibility and osteoconductivity. However, β-TCP is encountered with osteostimulation-deficiency and poor mechanical strength because of poor sinterability. Herein, we prepared novel β-TCP composite ceramics (TCP/SPGs) by introducing strontium-containing phosphate-based glass (SPG; 45P2 O5 -32SrO-23Na2 O) as sintering additive. The SPG helped to achieve efficient liquid-phase sintering of β-TCP at 1100 °C...

The effects of photodynamic therapy (PDT) are limited by the hypoxic tumor microenvironment (TME). In this paper, a new type of biocompatible multifunctional photosensitizer delivery system was fabricated to relieve tumor hypoxia and improve the efficacy of PDT. The photosensitizer hematoporphyrin monomethyl ether (HMME) and catalase (CAT) were encapsulated in the pores of mesoporous graphitic-phase carbon nitride nanosheets (mpg-C3 N4 ). Next, hyaluronic (HA) was coated on the surface of the mpg-C3 N4 via an amide linkage to construct the tumor-targeting HAase/CAT dual activatable and mpg-C3 N4 /HMME response photosensitizer delivery system (HA@mpg-C3 N4 -HMME/CAT)...

In this study, poly-l-lysine (PLL) immobilized PHEMA cryogel was designed for the specific bilirubin removal from human plasma. The surface of PHEMA cryogels is surrounded by PLL chains to enhance specific binding of bilirubin molecules via specific complementary electrostatic interactions. The functionalization of the PHEMA cryogel was carried out by direct coupling of PLL to pre-activated OH-group of the HEMA alcohol units via carbodiimide activation. Prior to removal of bilirubin from human plasma, the optimization parameters including, initial bilirubin concentration, flow rate, temperature, ionic strength, and adsorption rates on adsorption of PLL-PHEMA cryogel were investigated from the aqueous medium...

Limitation of current anti-Vascular Endothelial Growth Factor (VEGF) cancer therapy is transitory responses, inevitable relapses and its insufficient tumor-targeting. Thus, multifaceted approaches, including the development of bispecific antibodies and combination strategies targeting different pathways have been proposed as an alternative. Here, we developed a novel multi-paratopic VEGF decoy receptor, Cetuximab-VEGF-Grab and Trastuzumab-VEGF-Grab, by genetically fusing VEGF decoy receptor (VEGF-Grab) to a single chain Fv of anti-Epidermal Growth Factor Receptor (EGFR) antibody (Cetuximab and Trastuzumab)...

Phagocytosis and apoptosis are key cellular innate immune responses against bacteria and virus in invertebrates. Class B scavenger receptors (SRBs), which contain a CD36 domain, are critical pattern recognition receptors (PRRs) of phagocytosis for bacteria and apoptotic cells. In the present study, we identified a member of SRB subfamily in mud crab Scylla paramamosain, named Sp-SRB. The full-length cDNA of Sp-SRB is 2593 bp with a 1629 bp open reading frame (ORF) encoding a putative protein of 542 amino acids, and predicted to contain a CD36 domain with two transmembrane regions at the C- and N-terminals...
