A short synthesis of iminosugars and pipecolic acid derivatives has been realized through aldol addition of a pyruvate, a range of ketones and (S)-isoserinal, followed by catalytic reductive intramolecular amination. The stereoselective aldol reaction was achieved successfully by using tert ... more
We report fluorescent turn-on-and-off pH BODIPY probes which show drastic shift in pKa values upon introducing the electron withdrawing substituents on the meso-phenyl ring. The sensors utilize 4-amino- and 4-hydroxyl groups as proton receptors and works by intramolecular photoinduced elect ... more
The dependences on ionic strength of the hydrolysis constants of Fe3+ and of the first dissociation constant of sulfurous acid are briefly reviewed. The data are needed to derive from apparent stability constants reported in the literature the stability constants for the three iron–sulfito ... more
Wide bandgap materials are of significant importance in organic optoelectronic field. In this work, diphenylphosphine oxide-functionalized tetraphenylsilane moiety is designed and applied in the construction of wide bandgap materials. Wide bandgap polymer, PFSCPO, is synthesized via Suzuki ... more
The attachment of H2 to the full set of transition metal (TM) adatoms supported on graphene is studied by using density functional theory. Methodology validation calculations on the interactions of H2 with benzene and graphene show that any of the vdW corrections under study, the Grimme D2, ... more
Flocculation is a key purification step in cell-based processes for the food and pharmaceutical industry where the removal of cells and cellular debris is aided by adding flocculating agents. However, finding the best suited flocculating agent and optimal conditions to achieve rapid and eff ... more
A rapid and sensitive detection of a cancer marker, neuron specific enolase (NSE), is demonstrated by using a disposable silver plasmonic chip functionalized with a mussel-inspired polydopamine (PDA) coating. A plasmonic chip consisting of a diffraction grating coated with a silver thin fil ... more
A new turn-on near-infrared fluorescence probe (BDP) based on dibenzo[a,c]phenazine for superoxide anions detection with aggregation-induced emission property as well as a desirable large Stokes shift was designed and synthesized. After the reaction with superoxide, the initial diphenyl-pho ... more
In this study, we report the use of a high-throughput microfluidic spiral chip to screen out eggs from a mixed age nematode population, which can subsequently be cultured to a desired developmental stage. For the sorting of a mixture containing three different developmental stages, eggs, L1 ... more
The ultimate goal of modern structural biology is to probe proteins structure and dynamics in their physiological microenvironment. In-cell NMR spectroscopy is an ideal technique for achieving this goal, being able to investigate proteins at atomic-resolution in living cells. The reliabilit ... more

Hepatic stellate cells (HSCs) are major contributors to liver fibrosis, as hepatic injuries may cause their transdifferentiation into myofibroblast-like cells capable of producing excessive extracellular matrix proteins. Also, HSCs can modulate engraftment of transplanted hepatocytes and co ... more
Fatty metamorphosis is an uncommon alteration in uterine leiomyoma (i.e., lipoleiomyoma), and the pathogenetic mechanisms underlying this phenomenon remain poorly understood. Because a conditional deletion of β-catenin, a major transducer of the canonical Wingless/integrated (WNT) pathway, ... more
The chemokine receptor CXCR3 plays an important role in T cell recruitment in various immune responses and autoimmune diseases. Expression of CXCR3 ligands, including CXCL9, CXCL10, and CXCL11, is elevated in the salivary glands of patients with Sjögren’s syndrome (SS). To elucidate whether ... more
The size of peripheral T-cell pool is kept constant throughout life. However, a decline in lymphocyte numbers is a feature of several human disorders, in which fast and slow homeostatic proliferation play a crucial role. Several in vitro and in vivo models have been developed to study such ... more
A variety of laboratory methods are available for the detection of deletions of tumor suppressor genes and losses of their proteins. The clinical utility of fluorescence in situ hybridization (FISH) for the identification of deletions of tumor suppressor genes has previously been limited by ... more
Abstract Biodiesel production through the transesterification of oleaginous sources utilizing alkaline catalysts shows many process drawbacks like the need of a raw material with high purity degree and a high amount of alkaline wastewater generated from the biodiesel washing step. Such ... more
ABSTRACT A numerical study of flow in rotating pipes was conducted to elucidate the relative importance of convection and turbulence. CFD (Computational Fluid Dynamics) simulations of flow inside a rotating pipe (D = 2 cm and L/D = 20) were carried out, using the Reynolds Stress Model, ... more

Abstract The measurement of methane potential during anaerobic digestion has generally been accomplished through batch assays, yet the majority of industrial plants employ a semi‐continuous feeding regime and the estimation of continuous process yield from batch data is not straightforwa ... more
Abstract This study offers an advanced management system which adapts to most of the two‐stage anaerobic dry treatment plants that do not benefit from a local expert in biowaste treatment. This approach takes advantage of pH sensors to control the process within the optimal range to enha ... more
The European Food Safety Authority (EFSA) is responsible for risk assessment of all aspects of food safety, including the establishment of procedures aimed at the identification of emerging risks to food safety. Here, a scoring system was developed for identifying chemicals registered under ... more
Ubiquity of sulfonamides (SAs) in natural waters urges insights into their environmental fate for ecological risk assessment. Extensive studies focused on the effect of univariate water constituents on the photochemical fate of SAs, yet the multivariate effects of water constituents in envi ... more
Background: the effects of interaction between temperature and inhalable particulate matter (aerodynamic diameter < 10 μm, PM10) on mortality have been examined in some previous studies, but the results were inconsistent. This study aims to explore whether the effects of PM10 on daily non-a ... more
Abstract: Stormwater retention ponds effectively manage erosion, flooding, and pollutant loadings, but are also sources of methylmercury (MeHg), a bioaccumulative neurotoxin which is produced by anaerobic aquatic microorganisms. Stormwater retention ponds have a 10-15 year working life, aft ... more
Alkylated mercury species (monomethylmercury, MeHg, and dimethylmercury, DMeHg) exhibit significant bioaccumulation, and pose significant risks to ecosystems and human health. Although decades of research have been devoted to understanding MeHg formation and degradation, little is known abo ... more
