Recent studies have highlighted that the accidental acquisition of DNA from other species by invertebrate genomes is much more common than originally thought. The transferred DNAs are of bacterial or eukaryote origin and in both cases the receiver species may end up utilising the transferred genes for its own benefit. Frequent contact with prokaryotic DNA from symbiotic endocellular bacteria may predispose invertebrates to incorporate this genetic material into their genomes. Increasing evidence also points to viruses as major players in transferring genes and mobile elements between the species they infect...

Enterobacter sp. strain Bisph2 was isolated from a sandy soil from Biskra, Algeria and exhibits glyphosate-degrading activity. Multilocus sequence analysis of the 16S rRNA, rpoB, hsp60, gyrB and dnaJ genes demonstrated that Bisph2 might be a member of a new species of the genus Enterobacter. Genomic sequencing of Bisph2 was used to better clarify the relationships among Enterobacter species. Annotation and analysis of the genome sequence showed that the 5.535.656 bp genome of Enterobacter sp. Bisph2 consists in one chromosome and no detectable plasmid, has a 53...

The chemokine (C-C motif) receptor 5 (CCR5) serves as an HIV-1 co-receptor and is essential for cell infection with CCR5-tropic viruses. Loss of functional receptor protects against HIV infection. Here, we report the successful targeting of CCR5 in GFP-marked human induced pluripotent stem cells (iPSCs) using CRISPR/Cas9 with single and dual guide RNAs (gRNAs). Following CRISPER/Cas9-mediated gene editing using a single gRNA, 12.5% of cell colonies demonstrated CCR5 editing, of which 22.2% showed biallelic editing as determined by a Surveyor nuclease assay and direct sequencing...

Metastatic lung cancer is one of the most common cancers leading to mortality worldwide. Current treatment includes chemo- and pathway-dependent therapy aiming at blocking the spread and proliferation of these metastatic lesions. Nanomedicine is an emerging multidisciplinary field that offers unprecedented access to living cells and promises the state of the art in cancer detection and treatment. Development of nanomedicines as drug carriers (nanocarriers) that target cancer for therapy draws upon principles in the fields of chemistry, medicine, physics, biology, and engineering...

Autophagy is defined as an evolutionarily conserved process responsible for degradation of the cytoplasmic components including protein aggregates via the lysosomal machinery. Increasing evidence has linked defective autophagic degradation of protein aggregates with the pathogenesis of neurodegenerative disorders, and it is suggested that promotion of autophagy is regarded as a potential therapeutic for these diseases including Parkinson's disease (PD). Here we identified, 3-anhydro-6-hydroxy-ophiobolin A (X15-2), an ophiobolin derivative from Bipolaris oryzae that can strongly induce autophagic degradation of α-synuclein, the major constituent of Lewy bodies...

BACKGROUND: Fetal spinal magnetic resonance imaging (MRI) is a prenatal routine for proper assessment of fetus development, especially when suspected spinal malformations occur while ultrasound fails to provide details. Limited by hardware, fetal spine MR images suffer from its low resolution.High-resolution MR images can directly enhance readability and improve diagnosis accuracy. Image interpolation for higher resolution is required in clinical situations, while many methods fail to preserve edge structures...

Phage therapy may become a complement to antibiotics in the treatment of chronic Pseudomonas aeruginosa infection. To design efficient therapeutic cocktails, the genetic diversity of the species and the spectrum of susceptibility to bacteriophages must be investigated. Bacterial strains showing high levels of phage resistance need to be identified in order to decipher the underlying mechanisms. Here we have selected genetically diverse P. aeruginosa strains from cystic fibrosis patients and tested their susceptibility to a large collection of phages...

In this study, the relation of the nanostructure of cell walls with their texture was investigated for six different apple cultivars. Cell wall material (CWM) and cellulose microfibrils were imaged by atomic force microscope (AFM). The mean diameter of cellulose microfibrils for each cultivar was estimated based on the AFM height topographs obtained using the tapping mode of dried specimens. Additionally, crystallinity of cellulose microfibrils and pectin content was determined. Texture of apple cultivars was evaluated by sensory and instrumental analysis...

OBJECTIVE: MRI at 3 T is said to be more accurate than 1.5 T MR, but costs and other practical differences mean that it is unclear which to use. METHODS: We systematically reviewed studies comparing diagnostic accuracy at 3 T with 1.5 T. We searched MEDLINE, EMBASE and other sources from 1 January 2000 to 22 October 2010 for studies comparing diagnostic accuracy at 1.5 and 3 T in human neuroimaging. We extracted data on methodology, quality criteria, technical factors, subjects, signal-to-noise, diagnostic accuracy and errors according to QUADAS and STARD criteria...

The globalization of public health is both real and relevant throughout the United States and to Americans traveling or residing abroad. US public policy responses are evolving, but a crisper and more comprehensive global perspective is needed. I suggest four timely US actions to address today's competing realities of globalization and economic austerity: raise awareness among clinicians and local health departments; capture and share exemplary disaster management practices across countries; ensure that US global health investments are effective, efficient, and sustainable; and think globally while acting locally to enhance US health security...

Continuously-moving-table MRI, in contrast to traditional multistation techniques, potentially can improve the scan time efficiency of whole-body applications and provide seamless images of an extended field of view (FOV). Contrast-enhanced MR angiography (CE-MRA) in particular requires high spatial resolution and at the same time has rigid scan time constraints due to the limited arterial contrast window. In this study a reconstruction method for continuously acquired 3D data sets during table movement was combined with a self-calibrated partial parallel imaging algorithm (generalized autocalibrating partially parallel acquisitions (GRAPPA))...

Two speech processor programs (MAPs) differing only in electrode frequency boundary assignments were created for each of eight Nucleus 24 Cochlear Implant recipients. The default MAPs used typical frequency boundaries, and the experimental MAPs reassigned one additional electrode to vowel formant regions. Four objective speech tests and a questionnaire were used to evaluate speech recognition with the two MAPs. Results for the closed-set vowel test and the formant discrimination test showed small but significant improvement in scores with the experimental MAP...

The behavior of 16 volatile compounds of banana during a combination of air-drying (AD) and vacuum microwave-drying (VMD) of banana chips was characterized. Samples were AD to remove 60, 70, 80, or 90% of moisture (wet basis) and then subjected to VMD to achieve a final moisture content of 3% (dry basis). Banana slices were also dehydrated using only AD, VMD, and freeze-drying (FD) for comparison. Samples that underwent more VMD had significantly lower levels of volatile compounds, which is attributed to the decreased formation of an impermeable solute layer on the surface of the chips...

One of the most significant developments in imaging technology has been the process of digitalization. By incorporating currently available digital imaging equipment into surgical practice, urologists can be assured of obtaining real-time video images with optimal clarity and detail. In addition, one can efficiently capture and store still images that are crisper and sharper than their analog counterparts. These factors greatly improve the diagnostic capabilities and organization of today's endourologist.

Non-invasive wavefront sensing of the human eye provides the necessary information to design corrections which minimize the monochromatic optical errors of the eye beyond simple sphere (defocus) and cylinder (astigmatism). These "ideal" corrections must move with the eye, maintaining proper alignment with the eye's optics. Viable modes of correction include contact lenses, refractive surgery and intraocular lenses. Will these "ideal" corrections lead to better vision? If so, how much better? Here we explore the limits imposed by the optical and neural design of the eye...

BACKGROUND: The use of anti-reflection coatings (AR) for spectacle lenses is steadily increasing. These ultra-thin coatings reduce reflections in lenses, increasing light transmittance about 8% (from 91% to 99%). Patient reports of crisper detail and brighter environment indicate that this perceived increase in visual function would probably be of benefit to many, including highway patrolmen who must make daily judgments on the basis of fine visual detail. METHODS: Nineteen presbyopic Missouri State Highway Patrolmen (MSHP) participated in this crossover study...

Magnetic resonance imaging is frequently complicated by the presence of motion and susceptibility gradients. Also, some biologic tissues have short T2s. These problems are particularly troublesome in fast spin-echo (FSE) imaging, in which T2 decay and motion between echoes result in image blurring and ghost artifacts. The authors reduced TE in conventional spin-echo (SE) imaging to 5 msec and echo spacing (E-space) in FSE imaging to 6 msec. All magnetic gradients (except readout) were kept at a maximum, with data sampling as fast as 125 kHz and only ramp waveforms used...
