Fenalan Yellow G adsorption using surface-functionalized green nanoceria: An insight into mechanism and statistical modelling.

In the present study, green nanoceria (gNC) was synthesized and surface-functionalized (sf-gNC) with amine moieties through chemical means and used as an adsorbent for the removal of Fenalan Yellow G (FYG) from the aqueous solution. Prior to the adsorption process, the optical, structural and textural characteristics of the nanomaterial ensured the presence of highly crystalline and monodisperse nanoceria with the functionalized amine group on their surfaces. The effects of the independent variables of the FYG removal process including initial solution pH, adsorbent dose, initial adsorbate concentration and time were examined for the percent removal.

Host dietary specialization and neutral assembly shape gut bacterial communities of wild dragonflies.

Host-associated gut microbiota can have significant impacts on host ecology and evolution and are often host-specific. Multiple factors can contribute to such host-specificity: (1) host dietary specialization passively determining microbial colonization, (2) hosts selecting for specific diet-acquired microbiota, or (3) a combination of both. The latter possibilities indicate a functional association and should produce stable microbiota.

Constitutive Inflammatory Cytokine Storm: A Major Threat to Human Health.

Immune cells secrete small protein molecules that aim for cell-cell communications. These small molecules are called cytokines. Targeting cancer cells with administration of bispecific antibodies and natural extracts results in elevated circulating levels of inflammatory cytokines, including interferon-γ and interleukin (IL)-6, which lead to cell toxicity.

Vertebrate cranial mesoderm: developmental trajectory and evolutionary origin.

Vertebrate cranial mesoderm is a discrete developmental unit compared to the mesoderm below the developing neck. An extraordinary feature of the cranial mesoderm is that it includes a common progenitor pool contributing to the chambered heart and the craniofacial skeletal muscles. This striking developmental potential and the excitement it generated led to advances in our understanding of cranial mesoderm developmental mechanism.

Filovirus-reactive antibodies in humans and bats in Northeast India imply zoonotic spillover.

Biomaterials for topical and transdermal drug delivery in reconstructive transplantation.

Lifelong systemic immunosuppression remains the biggest challenge in vascularized composite allotransplantation (VCA) due to the adverse effects it causes. Since VCA is a life-enhancing procedure as compared with solid organ transplant which is life-saving; one needs to weigh the benefits and risks carefully. Thus, there is a huge unmet clinical need to design biomaterial-based vehicles that can deliver drugs more efficiently, topically and locally to eliminate adverse effects of systemic immune suppression.

Analysis of hepatic and retinal cell microRNAome during AAV infection reveals their diverse impact on viral transduction and cellular physiology.

Cellular microRNAs are known to modulate the life-cycle of different viruses. Surprisingly, very little data exists on AAV-induced changes to the cellular microRNAome in general and in hepatic and retinal cells, in particular. We reasoned that inducible microRNA in response to recombinant AAV infection may regulate immediate and long-lived cellular responses necessary for the cell's own survival as well as its ability to control several aspects of viral life-cycle.

Mitochondrial dysfunction plays a key role in the abrogation of cardioprotection by sodium hydrosulfide post-conditioning in diabetic cardiomyopathy rat heart.

Our previous study demonstrated that hydrogen sulfide post-conditioning (HPOC) renders cardioprotection against ischemia-reperfusion (I/R) injury in normal rat by preserving mitochondria. But its efficacy in ameliorating I/R in the diabetic heart with (DCM) or without cardiomyopathy (DM) is unclear and is the focus of the present study. Normal (N), diabetes mellitus (streptozotocin, 35 mg/kg; normal diet), and DCM (streptozotocin, 35 mg/kg; high-fat diet) rats were subjected to I/R (30 min global ischemia followed by 60 min reperfusion) in presence and absence of HPOC using ex vivo Langendorff perfusion system.

Automated detection of schizophrenia using nonlinear signal processing methods.

Examination of the brain's condition with the Electroencephalogram (EEG) can be helpful to predict abnormality and cerebral activities. The purpose of this study was to develop an Automated Diagnostic Tool (ADT) to investigate and classify the EEG signal patterns into normal and schizophrenia classes. The ADT implements a sequence of events, such as EEG series splitting, non-linear features mining, t-test assisted feature selection, classification and validation.

Vitamin K1 prevents diabetic cataract by inhibiting lens aldose reductase 2 (ALR2) activity.

This study investigated the potential of vitamin K1 as a novel lens aldose reductase inhibitor in a streptozotocin-induced diabetic cataract model. A single, intraperitoneal injection of streptozotocin (STZ) (35 mg/kg) resulted in hyperglycemia, activation of lens aldose reductase 2 (ALR2) and accumulation of sorbitol in eye lens which could have contributed to diabetic cataract formation. However, when diabetic rats were treated with vitamin K1 (5 mg/kg, sc, twice a week) it resulted in lowering of blood glucose and inhibition of lens aldose reductase activity because of which there was a corresponding decrease in lens sorbitol accumulation.

Biosorption of Rhodamine B onto novel biosorbents from Kappaphycus alvarezii, Gracilaria salicornia and Gracilaria edulis.

In the present investigation seaweeds of macroalgae like Kappaphycus alvarezii, Gracilaria salicornia and Gracilaria edulis used as novel biosorbent in native (KA, GS, GE) and ethanol modified (EKA, EGS, EGE) for Rhodamine B (RB) removal from aqueous solution in batch process. Effect of various biosorption parameters such as pH, initial concentration of RB, biosorbent dosage and contact time were studied. The maximum biosorption capacity determined as 9.

Post-translational modifications in capsid proteins of recombinant adeno-associated virus (AAV) 1-rh10 serotypes.

Post-translational modifications in viral capsids are known to fine-tune and regulate several aspects of the infective life cycle of several viruses in the host. Recombinant viruses that are generated in a specific producer cell line are likely to inherit unique post-translational modifications during intra-cellular maturation of its capsid proteins. Data on such post-translational modifications in the capsid of recombinant adeno-associated virus serotypes (AAV1-rh10) is limited.

NMDAR mediated translation at the synapse is regulated by MOV10 and FMRP.

Protein synthesis is crucial for maintaining synaptic plasticity and synaptic signalling. Here we have attempted to understand the role of RNA binding proteins, Fragile X Mental Retardation Protein (FMRP) and Moloney Leukemia Virus 10 (MOV10) protein in N-Methyl-D-Aspartate Receptor (NMDAR) mediated translation regulation. We show that FMRP is required for translation downstream of NMDAR stimulation and MOV10 is the key specificity factor in this process.

How Do Trait-Mediated Non-lethal Effects of Predation Affect Population-Level Performance of Mosquitoes?

Non-lethal, trait-mediated effects of predation impact prey behavior and life-history traits. Studying how these effects in turn influence prey demography is crucial to understand prey life-history evolution. Mosquitoes are important vectors that claim several million lives every year worldwide by transmitting a range of pathogens.

Live-Cell Fluorescence Imaging of RecN in Caulobacter crescentus Under DNA Damage.

Structural maintenance of chromosomes (SMC) proteins play a central role in the organization, segregation and maintenance of chromosomes across domains of life. In bacteria, an SMC-family protein, RecN, has been implicated to have important functions in DNA damage repair. Recent studies have suggested that RecN is required to increase chromosome cohesion in response to DNA damage and may also stimulate specific events during recombination-based repair.

Optimization of an in vitro bilayer model for studying the functional interplay between human primary retinal pigment epithelial and choroidal endothelial cells isolated from donor eyes.

Objective: The microenvironment of outer retina is largely regulated by retinal pigment epithelium (RPE) and choroid. Damage to either of these layers lead to the development of age related macular degeneration (AMD). A simplified cell culture model that mimics the RPE/Bruch's membrane (BM) and choroidal layers of the eye is a prerequisite for elucidating the molecular mechanism of disease progression.
