Intraflagellar transport (IFT) is a conserved mechanism essential for the assembly and maintenance of most eukaryotic cilia and flagella. However, little is known about its role in sperm flagella formation and male fertility. IFT140 is a component of IFT-A complex. In mouse, it is highly expressed in the testis. Ift140 gene was inactivated specifically in mouse spermatocytes/spermatids. The mutant mice did not show any gross abnormalities, but all were infertile associated with significantly reduced sperm number and motility...

The [(P,P)Au=C(Ph)CO2Et]+ complex 3 [where (P,P) is an o-carboranyl diphosphine ligand] was prepared by diazo decomposition at -40°C. It is the first alpha-oxo gold carbene complex to be characterized. Its crystallographic structure was determined and DFT calculations have been performed, unraveling the key influence of the chelating (P,P) ligand. The gold center is tricoordinate and the electrophilicity of the carbene center is reduced. Complex 3 mimics transient alpha-oxo gold carbenes in a series of catalytic transformations, and enables to support the critical role of electrophilicity in the chemoselectivity of phenol functionalization (O-H vs C-H insertion)...

During the last decades there has been a growing interest in the development of new solvents from biomass. Some of these new solvents have been classified as green due to their renewable and sustainable source. However, characterization from the ecotoxicological and physicochemical point of view is needed in order to categorize them as green solvents. We have selected several key physicochemical properties that can reflect environmental features (density, boiling point, critical aggregation concentration and Log P) and explored their usefulness for preliminary assessing the green character of the studied solvents...

Osteoarthritis (OA) is the most prevalent degenerative joint disease with multifactorial etiology caused by risk factors. The degradation of aggrecan by upregulated ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) is the key event in the development of OA. ADAMTS-4 contributes to aggrecan degradation in human OA. Cysteine-rich angiogenic inducer 61 (Cyr61), which is associated with diseases related to chronic inflammation, is found in articular cartilage from patients with osteoarthritis and appears to suppress ADAMTS-4 activity, possibly leading to chondrocyte cloning...

Profilin is one of the actin-binding proteins that regulate dynamics of actin polymerization. It plays a key role in cell motility and invasion. It also interacts with several other proteins notably through its poly-L-proline (PLP) binding site. Profilin in apicomplexa is characterized by a unique mini-domain consisting of a large β-hairpin extension and an acidic loop which is relatively longer in Plasmodium species. Profilin is essential for the invasive blood stages of Plasmodium falciparum. In the current study, unbound profilins from Plasmodium falciparum (Pf), Toxoplasma gondii (Tg) and Homo sapiens (Hs) were subjected to molecular dynamics (MD) simulations for a timeframe of 100 ns each to understand the conformational dynamics of these proteins...

The RNA-binding protein, UPF1, is best known for its central role in the nonsense-mediated RNA decay (NMD) pathway. Feng et al. now report a new function for UPF1-it is an E3 ubiquitin ligase that specifically promotes the decay of a key pro-muscle transcription factor: MYOD. UPF1 achieves this through its RING-like domain, which confers ubiquitin E3 ligase activity. Feng et al. provide evidence that the ability of UPF1 to destabilize MYOD represses myogenesis. In the future, it will be important to define other protein substrates of UPF1-driven ubiquitination and to determine whether this biochemical activity is responsible for some of UPF1's previously defined biological functions, including in development and stress responses...

Cellular mRNA levels are determined by the competing forces of transcription and decay. A wide array of cellular mRNA decay pathways carry out RNA turnover either on a constitutive basis or in response to changing cellular conditions. Here, we outline a method to investigate mRNA decay that employs RNAi knockdown of known or putative decay factors in commercially available Tet-off cell systems. Reporter mRNAs of interest are expressed under the control of a tetracycline-regulated promoter, allowing pulse-chase mRNA decay assays to be conducted...

Chemokines are small secreted proteins with chemoattractant properties that play a key role in inflammation. One such chemokine, Stromal cell-derived factor-1 (SDF-1) also known as CXCL12, and its receptor, CXCR4, are expressed and functional in cardiac myocytes. SDF-1 both stimulates and enhances the cellular signal which attracts potentially beneficial stem cells for tissue repair within the ischemic heart. Paradoxically however, this chemokine is known to act in concert with the inflammatory cytokines of the innate immune response which contributes to cellular injury through the recruitment of inflammatory cells during ischemia...

Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant spinocerebellar ataxia caused by CAG triplet expansion in atrophin 1 and is frequently associated with cerebral white matter lesions. To elucidate the clinical features of elderly onset DRPLA and the key radiological findings for differentiating DRPLA from physiological white matter lesions in healthy elderly subjects, we reviewed the clinical and magnetic resonance imaging (MRI) features of ten patients with elderly onset genetically confirmed DRPLA (> 60 years) and compared their MRI findings with those of age- and sex-matched ten healthy subjects with asymptomatic cerebral white matter lesions...

The innate immune system plays a critical role in the ethanol-induced neuroimmune response in the brain. Ethanol initiates the innate immune response via activation of the innate immune receptors Toll-like receptors (TLRs, e.g., TLR4, TLR3, TLR7) and NOD-like receptors (inflammasome NLRs) leading to a release of a plethora of chemokines and cytokines and development of the innate immune response. Cytokines and chemokines can have pro- or anti-inflammatory properties through which they regulate the immune response...

In the last decade, a wide range of avian influenza viruses (AIVs) have infected various mammalian hosts and continuously threaten both human and animal health. It is a result of overcoming the inter-species barrier which is mostly associated with gene reassortment and accumulation of mutations in their gene segments. Several recent studies have shed insights into the phenotypic and genetic changes that are involved in the interspecies transmission of AIVs. These studies have a major focus on transmission from avian to mammalian species due to the high zoonotic potential of the viruses...

Melanoma is a skin cancer with permanently increasing incidence and resistance to therapies in advanced stages. Reports of spontaneous regression and tumour infiltration with T-lymphocytes makes melanoma candidate for immunotherapies. Cytokines are key factors regulating immune response and intercellular communication in tumour microenvironment. Cytokines may be used in therapy of melanoma to modulate immune response. Cytokines also possess diagnostic and prognostic potential and cytokine production may reflect effects of immunotherapies...

As a diagnostic monitoring approach, electroencephalogram (EEG) signals can be decoded by signal processing methodologies for various health monitoring purposes. However, EEG recordings are contaminated by other interferences, particularly facial and ocular artifacts generated by the user. This is specifically an issue during continuous EEG recording sessions, and is therefore a key step in using EEG signals for either physiological monitoring and diagnosis or brain-computer interface to identify such artifacts from useful EEG components...

A biological denitrifying process was employed for the treatment of nanofiltration (NF) concentrate with high conductivity, which was generated from coking wastewater in a sequencing batch reactor (SBR). The results showed that the average removal efficiencies of chemical oxygen demand (COD), total nitrogen (TN) and nitrate were 47.6%, 61.1% and 94.6%, respectively. Different microbial communities were identified by sequencing the V1-V3 region of the 16S rRNA gene using the MiSeq platform, showing that the most abundant bacterial phylum in the SBR system was Proteobacteria, with the subclasses β-Proteobacteria and α-Proteobacteria being dominant...
