Previously, we reported that exposure to diisononyl phthalate (DINP) resulted in cognitive deficits and anxiety in mice (https//doi.org/10.1038/srep14676). Artificial light at night (ALAN) is now recognized as being a potential threat to human health. Osimertinib in vitro However, toxicological evidence concerning exposure to a combination of ALAN and DINP in vivo is limited. To this end, mice were orally exposed to different concentrations of DINP for 28 consecutive days, and ALAN (intensity 150 lux, every night for 12 h). The results showed that oxidative stress levels increased with increasing DINP exposure concentrations, which triggered apoptosis (Bcl-2 levels decreased, Bax levels increased), resulting in nerve cell damage and a decline in the learning and memory abilities of mice. The combined effects of ALAN and DINP exposure on the learning ability and memory of mice are more serious than for DINP exposure alone. The antioxidant vitamin E was shown to have a certain antagonistic effect on the oxidative damage caused by ALAN and DINP exposure. These results highlight a previously unknown relationship between exposure to ALAN and DINP-induced learning and memory impairment, and provide evidence that ALAN may be exacerbating the effects of DINP.Over the course of developing and applying a new real-time PCR assay for the detection of the newly described apple chlorotic fruit spot viroid (ACFSVd), slight modifications of the reverse transcription (RT) step were found to improve significantly the detection limit of the assay. To prove this hypothesis, three different one-step RT-qPCR kits for the detection of three plant viroids and three plant viruses were compared. The results showed both extension of the RT reaction time from 10 or 15 min-30 min or the increase in reaction temperature from 49 to 52 °C for the cDNA synthesis step results in a 10 times higher sensitivity for potato spindle tuber viroid and apple scar skin viroid one-step RT-qPCR assay and 45 higher sensitivity for ACFSVd one-step RT-qPCR assay. No variation in the detection limit was observed when the modifications were tested on tomato brown rugose fruit virus, plum pox virus and tomato ringspot virus assays. This finding is highly valuable for the investigation of viroids in general and could contribute to enhance sensitivity in their detection and to benefit regulatory outcomes for national plant protection organisations.American hop latent virus (AHLV), hop latent virus (HLV) and hop mosaic virus (HMV) infect members of the Humulus genus worldwide, but very little is known of the biology and etiology of these viruses. A better understanding of these viruses from the molecular level to their economic impact relies on efficient diagnostic assays. Therefore, in this study we developed reverse transcription quantitative polymerase chain reaction (RT-qPCR) assays for the detection of AHLV, HLV, and HMV through an alignment of representative sequences from the National Center for Biotechnology Information (NCBI) database. These assays demonstrated unambiguously their high sensitivity by detecting the respective targets from as low as 102 copies of transcripts per reaction without any amplification from non-targets.Highly pathogenic avian influenza viruses (HPAIVs) and low pathogenic avian influenza viruses (LPAIVs) represent important threats to the poultry industry and global human health. Due to the high rates of avian influenza virus (AIV) transmission, controlling AIV outbreaks is challenging. HPAIV is known to be transmitted from wild birds to domestic ducks, from which it can be transmitted to layer and broiler chickens. Therefore, surveillance of AIV in domestic ducks and chickens in advance of outbreaks can prevent its spread and enable timely implementation of disease control measures. Certain molecular diagnostic tools can be applied in the field for faster AIV detection. In this study, we evaluated the AIV-detection ability of two insulated isothermal PCR (iiPCR) devices, POCKIT™Micro DUO Nucleic Acid Analyzer (POCKIT DUO) and POCKIT™ Central Nucleic Acid Analyzer (POCKIT Central). We found that the analytical, in vivo and clinical performances of the two POCKIT devices were comparable to those of real-time reverse transcription PCR. Due to their brief protocols and short detection times, POCKIT DUO and POCKIT Central represent promising molecular diagnostic devices for the reliable detection of AIV.Myocardial infarction of cardiomyocytes is a leading cause of heart failure (HF) worldwide. Since heart has very limited regeneration capacity, cardiac tissue engineering (TE) to produce a bioactive scaffold is considered. In this study, a series of polyurethane solutions (5-7%wt) in aqueous acetic acid were prepared using electrospinning. A variety of Polyurethane (PU)/Chitosan (Cs)/carbon nanotubes (CNT) composite nanofibrous scaffolds with random and aligned orientation were fabricated to structurally mimic the extracellular matrix (ECM). Electrospun nanofibers were then characterized using field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), water contact angle, degradation studies, tensile tests, electrical resistance measurement and cell viability assay. The biocompatibility of electrospun random and aligned nanofibrous scaffolds with H9C2 Cells was confirmed. The results revealed that fabricated PU/Cs/CNT composite nanofibrous scaffolds were electro-conductive and aligned nanofibers could be considered as promising scaffolds with nano-scale features for regeneration of infarcted myocardium.This work intends to synthesis newer guar gum indole acetate ester and design film scaffolds based on protein-polysaccharide interactions for tissue engineering applications. Guar gum indole acetate(GGIA) was synthesized for the first time from guar gum in presence of aprotic solvent activated hofmeister ions. The newer biopolymer was fully characterized in FT-IR,13C NMR, XRD and TGA analysis. High DS (Degree of Substitution, DS = 0.61) GGIA was cross-linked with hydrolyzed keratin, extracted from chicken feather wastes. Films were synthesized from different biopolymer ratios and the surface chemistry appeared interesting. Physicochemical properties for GGIA-keratin association were notable. Fully bio-based films were non-cytotoxic and exhibited excellent biocompatibility for human dermal fibroblast cell cultivations. The film scaffold showed 63% porosity and the recorded tensile strength at break was 6.4 MPa. Furthermore, the standardised film exerted superior antimicrobial activity against both the Gram-positive and Gram-negative bacteria.
