In this work, the lanthanum oxide-aluminum oxide (La2O3-Al2O3) nanocomposite is introduced as an efficient photocatalyst for the photo-degradation of the dyes basic green 1 (BG1) and basic red 46 (BR46) in their binary aqueous solution under the UV light irradiation. The properties of this catalyst are determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Brunauer-Emmett-Teller (BET), and UV-visible spectrophotometry. The first-order derivative spectra are used for the simultaneous analysis of the dyes in their binary solution...

Radiation-induced intestinal injury (RIII) commonly occurs in patients who received radiotherapy for pelvic or abdominal cancer, or who suffered from whole-body irradiation during a nuclear accident. RIII can lead to intestinal disorders and even death given its integrity damage that results from intestinal stem cell (ISC) loss. Recovery from RIII relies on the intensity of supportive treatment, which can attenuate lethal infection and give surviving stem cells an opportunity to regenerate. It has been reported that RSPO1 is a cytokine with potent and specific proliferative effects on intestinal crypt cells...

Posttranslational conjugation of ubiquitin to proteins either regulates their function directly or concentration through ubiquitination dependent degradation. High degree of conservation of ubiquitin's sequence implies structural and functional importance of the conserved residues. Ubiquitin gene of Saccharomyces cerevisiae was evolved in vitro by us to study the significance of conserved residues. Present study investigates the structural changes in the protein resulting from the single mutations UbS20F, UbA46S, UbL50P, UbI61T and their functional consequences in the SUB60 strain of S...

BACKGROUND: While treatment of patients with moderate-to-severe psoriasis using a combination of fumaric acid esters (FAE, Fumaderm(®) ) and phototherapy (UV) is common practice, there have been hardly any studies investigating this regimen. Available information is limited to data from a small pilot study. The objective of the present study was to evaluate FAE/UV combination therapy in a larger patient cohort with moderate-to-severe psoriasis. PATIENTS AND METHODS: In this prospective noninterventional multicenter study, data from patients treated with FAE/UV combination therapy was assessed with regard to efficacy (PGA' PASI, DLQI, EQ-5D), safety, and dosage over a twelve-month period...

Parkinson's disease (PD), diffuse Lewy body disease (DLBD), and multiple system atrophy (MSA) constitute the three major neurodegenerative disorders referred to as synucleinopathies because both genetic and pathological results implicate the α-synuclein protein in their pathogenesis. PD and DLBD are recognized as closely related diseases with substantial clinical and pathological overlap. MSA, on the other hand, has a distinctive clinical presentation and neuropathological profile. In this review, we will summarize the evidence linking α-synuclein to these three disorders...

It has been puzzling whether and how a plant could exert a strong allelopathic inhibition to the target organisms by releasing low concentrations of allelochemicals. Plant allelochemicals have been proposed to be released continuously, however, direct evidence from specific allelochemicals is urgently required. In the present study, the toxicity of allelochemical N-phenyl-1-naphthylamine (NPN) towards the cyanobacterium Microcystis aeruginosa by two different exposure patterns was compared. One was low-dosage repeated exposure (LRE), in which 50  μg L(-1) NPN was repeatedly dosed to simulate the continual release of allelochemicals, and the other one was high-dosage single exposure (HSE) as per the routine toxicity assay...

siRNAs are very potent drug molecules, able to silence genes involved in pathologies development. siRNAs have virtually an unlimited therapeutic potential, particularly for the treatment of inflammatory diseases. However, their use in clinical practice is limited because of their unfavorable properties to interact and not to degrade in physiological environments. In particular they are large macromolecules, negatively charged, which undergo rapid degradation by plasmatic enzymes, are subject to fast renal clearance/hepatic sequestration, and can hardly cross cellular membranes...

BACKGROUND & AIMS: Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) persists as a stable episome in infected hepatocytes and serves as a template for the transcription of all viral genes. Due to the narrow host range of HBV, the development of a robust mouse model that supports cccDNA-dependent viral replication is a key hurdle in the development of novel HBV therapeutics. This study aimed to develop a novel tool to investigate HBV cccDNA. METHODS: Through minicircle technology, HBVcircle, a recombinant cccDNA, was easily generated and extracted from a genetically engineered E...

Multi-dose formulations of biotherapeutics, which offer better dosage management and reduced production costs, require the addition of antimicrobial preservatives (APs). APs have been shown, however, to decrease protein stability in solution and cause protein aggregation. In this report, the effect of four APs, m-cresol, phenol, phenoxyethanol and benzyl alcohol, on conformational stability, aggregation propensity and backbone flexibility of an IgG1 monoclonal antibody, mAb-4, is investigated. Compared to no preservative control, each of the APs decreased the conformational stability of mAb-4 as measured by DSC and extrinsic fluorescence spectroscopy...

Adsorption of lipid-based formulations, which are usually liquid, onto silicas has been extensively investigated in the past decade to convert them into solid dosage forms. There are conflicting reports on the ability of commercially available porous silicas, like Neusilin® US2, to release lipid formulations completely, especially after long-term storage. In this study, the release of a model drug, probucol, from different formulations of medium chain lipids and a surfactant, Kolliphor EL (Cremophor EL) or polysorbate 80, were studied after adsorbing them onto Neusilin® US2...

Cadmium is one of the most toxic heavy metals, which has been classified as human carcinogen and tetratogen. In the present study chitosan (CS) beads are modified, in a novel way, using sodium dodecyl sulfate (SDS), a well known anionic surfactant. The concentration of SDS has been judiciously selected to form surfactant bilayers on CS surface. These modified beads are designated as surfactant-modified chitosan (SMCS) beads. The adsorbent has been characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD)...

High-throughput screening (HTS) strategies and protocols have undergone significant development in the last decade. It is now possible to screen hundreds of thousands of compounds, each exploring multiple biological phenotypes and parameters, against various cell lines or model systems in a single setting. However, given the vast amount of data such studies generate, the fact that they use multiple reagents, and are often technician-intensive, questions have been raised about the variability, reliability and reproducibility of HTS results...
