Honghai Zhang, Haiting Zhao, Hua-Jun Feng
Sudden unexpected death in epilepsy (SUDEP) is a devastating epilepsy complication, and no effective preventive strategies are currently available for this fatal disorder. Clinical and animal studies of SUDEP demonstrate that seizure-induced respiratory arrest (S-IRA) is the primary event leading to death after generalized seizures in many cases. Enhancing brain levels of serotonin reduces S-IRA in animal models relevant to SUDEP, including the DBA/1 mouse. Given that serotonin in the brain plays an important role in modulating respiration and arousal, these findings suggest that deficits in respiration and/or arousal may contribute to S-IRA...

BACKGROUND: Bioluminescent proteins (BLPs) widely exist in many living organisms. As BLPs are featured by the capability of emitting lights, they can be served as biomarkers and easily detected in biomedical research, such as gene expression analysis and signal transduction pathways. Therefore, accurate identification of BLPs is important for disease diagnosis and biomedical engineering. In this paper, we propose a novel accurate sequence-based method named PredBLP (Prediction of BioLuminescent Proteins) to predict BLPs...

We report the synthesis and characterization of a conjugated polymer incorporated with cyclometalated platinum complexes on the main chain. The polymer may serve as an efficient triplet sensitizer in light-harvesting systems. The photophysical properties of the polymer were studied by nanosecond and femtosecond time-resolved transient absorption spectroscopies. After excitation, an energy-transfer process from the thiophene units on the conjugated main chain to the singlet excited state of the Pt complex moieties occurred in less than 150 fs...

EGF receptor (EGFR) is a critical signaling node throughout life. However, it has not been possible to directly visualize endogenous Egfr in mice. Using CRISPR/Cas9 genome editing, we appended a fluorescent reporter to the C terminus of the Egfr. Homozygous reporter mice appear normal and EGFR signaling is intact in vitro and in vivo. We detect distinct patterns of Egfr expression in progenitor and differentiated compartments in embryonic and adult mice. Systemic delivery of EGF or amphiregulin results in markedly different patterns of Egfr internalization and trafficking in hepatocytes...

RATIONALE: Kennedy disease (KD) is also known as spinal bulbar muscular dystrophy. As KD has similar symptoms with most neuromuscular diseases, so it is difficult to make a rapid diagnosis clinically. PATIENT CONCERNS: We report a case of a 43-year-old male with progressive limb proximal weakness without family history. Physical examination showed gynecomastia, erectile dysfunction, bilateral tendon reflex and quadriceps weakness, and tongue muscle atrophy. DIAGNOSES: Laboratory examination found increased creatine kinase, impaired glucose tolerance, and abnormal lactic acid values...

Haiting Zhang, Yongbo Dan, Craig D Adams, Honglan Shi, Yinfa Ma, Todd Eichholz
In this research, the release and degradation of intracellular microcystin-LR (MC-LR) due to oxidation of Microcystis aeruginosa (M. aeruginosa) was examined kinetically. Brief exposure to free chlorine with no measureable oxidant exposure was demonstrated to be sufficient to induce rapid release of intracellular MC-LR from M. aeruginosa. Thus, in a water treatment plant, there is currently no level of prechlorination that can be assumed to be safe, since very low preoxidation prior to filtration and no measureable free chlorine residual may still observe the release and buildup of extracellular MC-LR...

In this study, single particle mass spectra signatures of both coal burning boiler and biomass burning boiler emitted particles were studied. Particle samples were suspended in clean Resuspension Chamber, and analyzed by ELPI and SPAMS simultaneously. The size distribution of BBB (biomass burning boiler sample) and CBB (coal burning boiler sample) are different, as BBB peaks at smaller size, and CBB peaks at larger size. Mass spectra signatures of two samples were studied by analyzing the average mass spectrum of each particle cluster extracted by ART-2a in different size ranges...

Ustekinumab is approved for the treatment of psoriasis in adolescents and for the treatment of moderate to severe Crohn's disease (CD) in adults, but data are lacking in pediatric CD. We report a case of severe psoriasis induced by biotherapies in an adolescent with CD that improved after switching to ustekinumab (90 mg at weeks 0, 2, and 4 and then every 8 weeks). The patient had not experienced CD relapse after 1 year of follow-up. Ustekinumab can be an alternative therapy for psoriasis induced by biotherapies when conventional treatment fails and can maintain remission of CD...

We demonstrate a facile method to induce water droplet motion on an wedge-shaped superhydrophobic copper surface combining with a poly(dimethylsiloxane) (PDMS) oil layer on it. The unbalanced interfacial tension from the shape gradient offers the actuating force. The superhydrophobicity critically eliminates the droplet contact line pinning and the slippery PDMS oil layer lubricates the droplet motion, which makes the droplet move easily. The maximum velocity and furthest position of droplet motion were recorded and found to be influenced by the gradient angle...

Ester Hait, Guy Gilboa
We propose a new way to solve a very general blind inverse problem of multiple simultaneous degradations, such as blur, resolution reduction, noise, and contrast changes, without explicitly estimating the degradation. The proposed concept is based on combining semantic non-rigid patches, problem-specific high-quality prior data, and non-rigid registration tools. We show how a significant quality enhancement can be achieved, both visually and quantitatively, in the case of facial images. The method is demonstrated on the problem of cellular photography quality enhancement of dark facial images for different identities, expressions, and poses, and is compared with the state-of-the-art denoising, deblurring, super-resolution, and color-correction methods...

We previously reported that single cells from a human colorectal cancer (CRC) cell line (HCA-7) formed either hollow single-layered polarized cysts or solid spiky masses when plated in 3D in type-I collagen. To begin in-depth analyses into whether clonal cysts and spiky masses possessed divergent properties, individual colonies of each morphology were isolated and expanded. The lines thus derived faithfully retained their parental cystic and spiky morphologies and were termed CC (cystic) and SC (spiky), respectively...

Graphene quantum dots (GQDs) have received much research attention, because of their useful structure and optical absorption/emission. We report the tunable amplified spontaneous emission (ASE) in GQD-doped cholesteric liquid crystal (CLC), which to the best of our knowledge has not been previously observed. The GQDs are uniformly dispersed with a weight ratio of 0.5 wt.% in CLC. Under optical excitation, typical ASE is triggered in the system at pump energies greater than 1.25 mJ cm(-2). The emission peak at the long wavelength edge of the photonic bandgap shifts from 662 to 669 nm, as the working temperature is increased from 50 to 90 °C...

A series of color-tunable Ca3-2x-y-z SiO4 Cl2 (CSC):xCe(3+) ,xLi(+) ,yMn(2+) ,zEu(2+) phosphors with low temperature phase structure was synthesized via the sol-gel method. An energy transfer process from Ce(3+) to Mn(2+) in CSC:0.01Ce(3+) ,0.01Li(+) ,yMn(2+) (y = 0.03-0.09) and the mechanism was verified to be an electric dipole-dipole interaction. The Ce(3+) and Mn(2+) emission intensities were greatly enhanced by co-doping Eu(2+) ions into CSC:0.01Ce(3+) ,0.01Li(+) ,0.07Mn(2+) phosphors due to competitive energy transfers from Eu(2+) /Ce(3+) to Mn(2+) , and Ce(3+) to Eu(2+) ...

Temozolomide (TMZ)-based chemotherapy is a standard strategy for glioma, while chemoresistance remains a major therapeutic challenge. Recent evidence highlights the crucial regulatory roles of long non-coding RNAs (lncRNA) in tumor biology. However, the roles and regulatory mechanisms of lncRNA cancer susceptibility candidate 2 (CASC2), in glioma tumorigenesis and chemoresistance are poorly understood. In this study, CASC2 expression was down-regulated in glioma tissues and cell lines, and was related to a clinicopathologic features and shorter survival time...

Many studies have revealed a protective effect of infection of an individual with an immunodeficiency virus against subsequent infection with a heterologous strain. However, the extent of protection against superinfection conferred by the first infection and the biological consequences of superinfection are not well understood. Here, we report that a rhesus monkey model of mucosal superinfection was established to investigate the protective immune response. Protection against superinfection was shown to correlate with the extent of the polyfunctionality of CD4(+) effector memory T cells, whereas neutralizing antibody responses did not protect against superinfection in this model...
