Genomic waves

Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen subdivided into lineages termed sequence types (STs). Since the 1950s, successive waves of STs have appeared and replaced previously dominant lineages. One such event has been occurring in China since 2013, with community-associated (CA-MRSA) strains including ST59 largely replacing the previously dominant healthcare-associated (HA-MRSA) ST239.

The history of human populations occupying the plains and mountain ridges separating Europe from Asia has been eventful, as these natural obstacles were crossed westward by multiple waves of Turkic and Uralicspeaking migrants as well as eastward by Europeans.

The importance of transcription factors (TFs) and epigenetic modifications in the control of gene expression is widely accepted. However, causal relationships between changes in TF binding, histone modifications, and gene expression during the response to extracellular stimuli are not well understood. Here, we analyze the ordering of these events on a genome-wide scale in dendritic cells in response to lipopolysaccharide (LPS) stimulation.

Human pluripotent stem cells offer the best available model to study the underlying cellular and molecular mechanisms of human embryonic lineage specification. However, it is not fully understood how individual stem cells exit the pluripotent state and transition towards their respective progenitor states.

The aim of this research was to design an electrochemical immunosensor for determination of tumour necrosis factor receptor-associated protein-1(TRAP1) antigen, a heat shock protein linked to tumour necrosis factor. The indium-tin oxide covered polyethylene terephthalate (ITO-PET) electrode surface was cleaned and was prepared for the introduction of hydroxyl groups on its surface by using NH4 OH/H2 O2 /H2 O. As a silanization agent for covalent attachment of anti-TRAP1 on the surface of the ITO working electrode, 3-glycidoxypropyltrimethoxysilane (3-GOPS) was used.

Prolongation of superstimulatory treatment appears to be associated with a greater superovulatory response and with greater oocyte maturation in cattle. A genome-wide bovine oligo-microarray was used to compare the gene expression of granulosa cells collected from ovarian follicles after differing durations of the growing phase induced by exogenous FSH treatment.

Influenza viruses are undergoing continuous and rapid evolution. The fatal influenza A/H7N9 has drawn attention since the first wave of infections in March 2013, and raised more grave concerns with its increased potential to spread among humans. Experimental studies have revealed several host and virulence markers, indicating differential host binding preferences which can help estimate the potential of causing a pandemic. Here we systematically investigate the sequence pattern and structural characteristics of novel influenza A/H7N9 using computational approaches.

In studies of case-parent trios, we define copy number variants (CNVs) in the offspring that differs from the parental copy numbers as de novo and of interest for their potential functional role in disease. Among the leading array-based methods for discovery of de novo CNVs in case-parent trios is the joint hidden Markov model (HMM) implemented in the PennCNV software.

The continued democratization of DNA sequencing has sparked a new wave of development of genome assembly and assembly validation methods. As individual research labs, rather than centralized centers, begin to sequence the majority of new genomes, it is important to establish best practices for genome assembly.

The maintenance of plant genome integrity plays a critical function in the processes of DNA replication, transcription, and repair. Short-wave UV radiation (UVC) is among the most harmful agents known to affect genome stability and to induce DNA damage, including double-strand breaks (DSBs).

Using the four waves, we construct hourly wages corresponding to the individual’s job at the time of response to the survey indexed to the monthly level, spanning the years 1990 to 1998. 16 We only include wages for full-time jobs (at least 35 hours a week). As shown in Table 2, the variation in enrollment across waves translates into considerable overlap in the pre- and post-MBA wages, particularly in the middle years, 1993 and 1994.

Liquid Robotics’ chief of innovative applications, Edward Lu, a former astronaut, often remarks that we know more about outer space than we do about the oceans on which most of life on Earth depends for survival. The company’s Wave Glider, which looks like a surf board packed with instruments, is trying to change that. Company founder Roger Hine got the idea when an investor asked him how he would track the migratory routes of humpback whales. The gliders, which rely on wave motion to maintain a speed of around 1.5 knots and count on solar energy to power transmitters that...

Second, the prospects for major child health reform will diminish as resources become increasingly scarce.Health care spending that is already hitting the “high- water mark” of 16 percent of U.S. gross domestic product (GDP) and predictably increasing in the face of the next wave of genomics-driven technological innova- tions will be swamped by the approaching “Silver Tsunami.” As baby boomers re- tire in larger numbers and use ever-greater amounts of health care, the Congres- sional Budget Office estimates health spending climbing well over 20 percent of GDP in the next decade.
