The efficient and mild copper-catalyzed synthesis of unsymmetrical diorganyl chalcogenides under ligand- and solvent-free conditions is described. The cross-coupling reaction was performed using aryl boric acids and 0.5 equiv. of diorganyl dichalcogenides (Te/Se/S) in the presence of 3 mol % of CuI and 3 equiv. of DMSO, under microwave irradiation. This new protocol allowed the preparation of several unsymmetrical diorganyl chalcogenides in good to excellent yields.

Significant correlations between the response to induction chemotherapy and success of subsequent radiotherapy have been reported and suggest that the response to induction chemotherapy is able to predict a response to radiotherapy. Therefore, induction chemotherapy may be used to tailor the treatment plan to the individual patient with head and neck cancer: following the planned subsequent (chemo)radiation schedule, planning a radiation dose boost, or reassessing the modality of treatment (eg, upfront surgery)...

A deficiency of the enzyme arylsulfatase A (ARSA) causes a progressive neurodegenerative lysosomal storage disease known as metachromatic leukodystrophy (MLD). Diagnosis is based on the onset of neurological symptoms, presence of gait abnormalities, spasticity, decreased muscle stretch reflexes and neuro-radiological evidence of demyelination. The purpose of the present study was to identify any mutation in the candidate ARSA gene in a family of late infantile MLD patients. The diagnosis of suspected MLD patients was confirmed by a MRI report and low ARSA enzymatic activity in leukocytes...

The origin of the dissolution of MAPI crystals in liquid water is clarified by finite temperature molecular dynamics by developing a MYP-based force field (MYP1) for water-MAPI systems. It is found a thermally activated process with an energy barrier of 0.36 eV consisting of a layer by layer degradation with generation of inorganic PbI films and solvation of MA and I ions. We rationalize the effect of water on MAPI by identifying a transition from a reversible absorption and diffusion in presence of vapor, to the irreversible destruction of the crystal lattice in liquid due to a cooperative action of water molecules...

Osteonecrosis of the femoral head (ONFH) is a debilitating disease that results in progressive collapse of the femoral head and subsequent degenerative arthritis. Few treatments provide both sufficient mechanical support and biological cues for regeneration of bone and vascularity when the femoral head is still round and therefore salvageable. We designed and 3D printed a functionally-graded scaffold (FGS) made of polycaprolactone (PCL) and β-tricalcium phosphate (β-TCP) with spatially controlled porosity, degradation and mechanical strength properties to reconstruct necrotic bone tissue in the femoral head...

Several mutations in the genes encoding α-crystallin (α-Cry) subunits have been indicated to cause cataract diseases in human. Also, elevation in calcium level has been shown to induce aggregation of α-Cry which is accompanied with a significant reduction in its chaperone function. In some pathological conditions, the simultaneous incidence of α-Cry mutation and lens electrolyte imbalance might exacerbate the cataract phenotype. Therefore, in this study, the impact of calcium ion was investigated on structure, chaperone activity and amyloidogenic properties of the recombinant wild-type and mutant R12C αA-Cry, in a comparative study...

Bronchial asthma (BA) is a chronic inflammatory disorder of airways for which the effective therapies include inhaled corticosteroids (ICS) and short-acting β2-adrenoreceptor agonist (SABA). Serum eosinophil cationic protein (ECP) has been reported to reflect the degree of airway inflammation. We, therefore, explored the implication of serum ECP in assessing the efficacy of ICS therapy in BA children. Our prospective randomized control study enrolled 126 BA children and 78 healthy children (the control group)...
