The present invention discloses methods and systems to control magnetic fields and magnetic field induced currents, and more particularly to provide stimulations within a patients body, such as deep brain stimulation, in a non-invasive manner and with greater focus and control than has been afforded by prior known methods and systems. In accordance with certain aspects of an embodiment, an array of magnetic coils is provided and positionable about a portion of a patients body. During operation, at least some of the magnetic coils function as DC coil pairs configured to generate a DC magnetic field, while at least some of the other magnetic coils function as transient magnetic field generators to generate an induced current within a portion of the patients body, such as in a region of the patients brain. The system is configured such that the DC magnetic fields may be used to manipulate the transient magnetic fields, in turn allowing significantly improved control and focus of the induced current within a specifically desired volume of interest within a patients body.

The present invention provides for nutrient extraction and recovery devices that use the Donnan Membrane Principle (DMP) to cause spontaneous separation of dissolved ions along electrochemical potential gradients, wherein anions and cations such as H_(2)PO_(4)^(), HPO_(4)^(2), PO_(4)^(3), Mg^(2+), Ca^(2+), NH_(4)^(+), and K^(+) are moved from manure containing waste streams through cation and anion exchange membranes into a recovery stream thereby precipitating target compounds including but not limited to struvite, potassium struvite and hydroxyapatite.

The claustrum is among the most enigmatic of all prominent mammalian brain structures. Since the 19th century, a wealth of data has amassed on this forebrain nucleus. However, much of this data is disparate and contentious; conflicting views regarding the claustrum's structural definitions and possible functions abound. This review synthesizes historical and recent claustrum studies with the purpose of formulating an acceptable description of its structural properties. Integrating extant anatomical and functional literature with theorized functions of the claustrum, new visions of how this structure may be contributing to cognition and action are discussed. © 2014 Mathur.

The past 15 years have seen a rapid increase in our understanding of orbitofrontal function. Today this region is the focus of an enormous amount of research, including work on such complex phenomena as regret, ambiguity, and willingness to pay. The orbitofrontal cortex is also credited as a major player in a host of neuropsychiatric diseases. This transformation arguably began with the application of concepts derived from animal learning theory. We will review data from studies emphasizing these approaches to argue that the orbitofrontal cortex forms a crucial part of a network of structures that signals information about expected outcomes. Further we will suggest that, within this network, the orbitofrontal cortex provides the critical ability to integrate information in real-time to make what amounts to actionable predictions or estimates about future outcomes. As we will show, the influence of these estimates can be demonstrated experimentally in appropriate behavioral settings, and their operation can also readily explain the role of orbitofrontal cortex in much more complex phenomena such as those cited above.

Human papillomavirus (HPV), one of the most common sexually transmitted diseases worldwide, has an established role in the pathogenesis of genital malignancies such as cervical cancer. The virus has also been implicated in the oncogenesis of nongenital cancers including head and neck malignancies (specifically oropharyngeal cancers) as well as anal cancer. There is less clarity regarding its role in lung and esophageal cancers. Worldwide, the incidence and prevalence of HPV-associated oropharyngeal cancer has been increasing over time. These patients have improved outcomes compared with those with HPV-negative oropharyngeal cancers, and there is continued interest in designing treatments specifically for this HPV-positive subgroup. Clinicians continue to gain an understanding of HPV in anal cancers and the risk factors associated with infection and progression to malignancy. This has potential implications for the eventual screening of high-risk groups. While HPV vaccination is currently approved for the prevention of cervical cancer, it also has potential in the prevention of all HPV-associated malignancies. In this review, current understanding of the role of HPV in nongenital cancers is discussed, as well as future implications for treatment and prevention.

The primary functions of the gastrointestinal tract have traditionally been perceived to be limited to the digestion and absorption of nutrients and to electrolytes and water homeostasis. A more attentive analysis of the anatomic and functional arrangement of the gastrointestinal tract, however, suggests that another extremely important function of this organ is its ability to regulate the trafficking of macromolecules between the environment and the host through a barrier mechanism. Together with the gut-associated lymphoid tissue and the neuroendocrine network, the intestinal epithelial barrier, with its intercellular tight junctions, controls the equilibrium between tolerance and immunity to non-self antigens. Zonulin is the only physiological modulator of intercellular tight junctions described so far that is involved in trafficking of macromolecules and, therefore, in tolerance/immune response balance. When the finely tuned zonulin pathway is deregulated in genetically susceptible individuals, both intestinal and extraintestinal autoimmune, inflammatory, and neoplastic disorders can occur. This new paradigm subverts traditional theories underlying the development of these diseases and suggests that these processes can be arrested if the interplay between genes and environmental triggers is prevented by reestablishing the zonulin-dependent intestinal barrier function. This review is timely given the increased interest in the role of a "leaky gut" in the pathogenesis of several pathological conditions targeting both the intestine and extraintestinal organs.

Formation of a bacterial biofilm is a developmental process that begins when a cell attaches to a surface, but how does a bacterial cell know it is on or near a surface in the first place? The phase of this 'swim-or-stick' switch is determined by a sensory transduction mechanism referred to as surface sensing, which involves the rotating bacterial flagellum. This review explores six bacterial species as models of flagellar mechanosensing of surfaces to understand the current state of our knowledge and the challenges that lie ahead. A common link between these bacteria is a requirement for the proper function of the flagellar motor stators that channel ions into the cell to drive flagellar rotation. Conditions that affect ion flow act as a signal that, ultimately, controls the master transcriptional regulatory circuits controlling the flagellar hierarchy and biofilm formation. © 2014 Elsevier Ltd.

This paper reviews the history of mechanochemistry. It begins with prehistoric times, when reactions could be initiated during grinding and rubbing accidentally, and follows the main developments until recent results and current trends. There are very few records on mechanochemistry until the first systematic investigations by Spring and Lea at the end of the 19th century. For the next decades, mechanochemistry developed slowly; minerals, inorganic compounds, and polymers were the main subjects of investigation. The area became more organized in the 1960s, when several large groups were established and the first dedicated conferences were held. Mechanical alloying was invented in 1966 independently and it became a subject of intense research. Interaction between the two topics was established in the 1990s. In recent years, the mechanochemical synthesis of organic compounds was added to the main subjects and the invention of the atomic force microscope provided new ways to manipulate atoms and molecules by direct mechanical action. The theoretical explanation of mechanochemical phenomena is difficult, as the mechanism is system specific and several length and time scales are involved. Thiessen proposed the first theory, the magma-plasma model, in 1967, and deeper insight is being obtained by computer modelling combined with empirical work. Practical applications have been an important motivation throughout the history of mechanochemistry. It is used alone or in combination with other steps in an increasing number of technologies. © 2013 The Royal Society of Chemistry.
