Passive houses and other highly energy-efficient buildings need mechanical ventilation. However, ventilation systems in such houses are regarded with a certain degree of skepticism by parts of the public due to alleged negative health effects. Within a quasi-experimental field study, we investigated if occupants of two types of buildings (mechanical vs. natural ventilation) experience different health, wellbeing and housing satisfaction outcomes and if associations with indoor air quality exist. We investigated 123 modern homes (test group: with mechanical ventilation; control group: naturally ventilated) built in the years 2010 to 2012 in the same geographic area and price range...

REVIEW
Nathan T Fried, Melanie B Elliott, Michael L Oshinsky
Migraine is the third most prevalent disease on the planet, yet our understanding of its mechanisms and pathophysiology is surprisingly incomplete. Recent studies have built upon decades of evidence that adenosine, a purine nucleoside that can act as a neuromodulator, is involved in pain transmission and sensitization. Clinical evidence and rodent studies have suggested that adenosine signaling also plays a critical role in migraine headache. This is further supported by the widespread use of caffeine, an adenosine receptor antagonist, in several headache treatments...

The present report proposes a more rational hyaluronic acid (HA) conjugation protocol that can be used to modify the surface of the superparamagnetic iron oxide nanoparticles (SPIONs) by covalently binding the targeting molecules (HA) with glutamic acid as a molecular linker on peripheral surface of SPIONs. The synthesis of HA-Glutamic Acid (GA)@SPIONs was included oxidization of nanoparticle's surface with H₂O₂ followed by activation of hydroxyl group and reacting glutamic acid as an intermediate molecule demonstrating transfection of lung cancer cells...

The aggregation and colloidal stability of three, commercially-available, gamma-aluminum oxide nanoparticles (γ-Al₂O₃ NPs) (nominally 5, 10, and 20-30 nm) were systematically examined as a function of pH, ionic strength, humic acid (HA) or clay minerals (e.g., montmorillonite) concentration using dynamic light scattering and transmission electron microscopy techniques. NPs possess pH-dependent surface charges, with a point of zero charge (PZC) of pH 7.5 to 8. When pH < PZC, γ-Al₂O₃ NPs are colloidally stable up to 100 mM NaCl and 30 mM CaCl₂...

Glycosaminoglycans (GAGs) have therapeutic potential in areas ranging from angiogenesis, inflammation, hemostasis and cancer. GAG bioactivity is conferred by intrinsic structural features, such as disaccharide composition, glycosidic linkages and sulfation pattern. Unfortunately, the in vitro enzymatic synthesis of defined GAGs is quite restricted by a limited understanding of current GAG synthases and modifying enzymes. Our work provides insights into GAG-active enzymes through the creation of sulfated oligosaccharides, a new polysaccharide and chimeric polymers...

Multifunctional nanoprobe was drawing increased attention in tumor diagnosis and therapy. The simple and effective establishment of the theranostic nanoplatforms was still under urgent need. Meanwhile, the targeting ability and morphology of nanoprobe were essential for the effective endocytosis, which could further affect the diagnosis. In this work, two morphologies of nanoprobes were fabricated using gold nanorods (AuNRs) and gold nanospheres (AuNSs). Thiolated-hyaluronic acid labeled with nile blue (HS-HA-NB), a near-infrared (NIR) fluorescence dye, was coated on the surface of the gold nanoparticles to form stable nanoprobes (AuNR@HS-HA-NB, AuNS@HS-HA-NB)...

The removal of a commercial humic acid (HA) and changes in its chemical composition were examined for coagulation/flocculation (C/F) processes based on jar tests using two different coagulants at a wide range of pH. ZrCl4 showed a better performance in eliminating HA than Al2SO4 with the same removal rates at lower dosages. The highest removal rates were found at a neutral pH range (5.0-6.5). The HA was further decomposed into three different humic-like components (C1, C2, and C3) by excitation emission matrix coupled with parallel factor analysis (EEM-PARAFAC)...
