    Tubal blockage is one of the most important factors for female infertility. This condition is not described in Ayurvedic classics, as the fallopian tube itself is not mentioned directly there. The present study is an effort to understand the disease according to Ayurvedic principles. Correlating fallopian tubes with the Artavavaha (Artava-bija-vaha) Srotas, its block is compared with the Sanga Srotodushti of this Srotas. Charak's opinion that the diseases are innumerable and newly discovered ones should be understood in terms of Prakriti, Adhishthana, Linga, and Aayatana, is followed, to describe this disease. An effort has been made to evaluate the role of all the three Doshas in producing blockage, with classification of the disease done as per the Dasha Roganika. PMID:22131704

    A flux of cosmic rays (CRs) propagating through a diffuse ionized gas can excite MHD waves, thus generating magnetic disturbances. We propose a generic model of CR penetration into molecular clouds through their diffuse envelopes, and identify the leading physical processes controlling their transport on the way from a highly ionized interstellar medium to the dense interior of the cloud. The model allows us to describe a transition between a free streaming of CRs and their diffusive propagation, determined by the scattering on the self-generated disturbances. A self-consistent set of equations, governing the diffusive transport regime in an envelope and the MHD turbulence generated by the modulated CR flux, is characterized by two dimensionless numbers. We demonstrate a remarkable mutual complementarity of different mechanisms leading to the onset of the diffusive regime, which results in a universal energy spectrum of the modulated CRs. In conclusion, we briefly discuss implications of our results for several fundamental astrophysical problems, such as the spatial distribution of CRs in the Galaxy as well as the ionization, heating, and chemistry in dense molecular clouds. This paper is dedicated to the memory of Prof. Vadim Tsytovich.

  14. ON THE ACCURACY OF THE PROPAGATION THEORY AND THE QUALITY OF BACKGROUND OBSERVATIONS IN A SCHUMANN RESONANCE INVERSION PROCEDURE Vadim MUSHTAK, Earle WILLIAMS PARSONS LABORATORY, MIT

    Observations of electromagnetic fields in the Schumann resonance (SR) frequency range (5 to 40 Hz) contain information about both the major source of the electromagnetic radiation (repeatedly confirmed to be global lightning activity) and the source-to-observer propagation medium (the Earth-ionosphere waveguide). While the electromagnetic signatures from individual lightning discharges provide preferable experimental material for exploring the medium, the properties of the world-wide lightning process are best reflected in background spectral SR observations. In the latter, electromagnetic contributions from thousands of lightning discharges are accumulated in intervals of about 10-15 minutes - long enough to present a statistically significant (and so theoretically treatable) ensemble of individual flashes, and short enough to reflect the spatial-temporal dynamics of global lightning activity. Thanks to the small (well below 1 dB/Mm) attenuation in the SR range and the accumulated nature of background SR observations, the latter present globally integrated information about lightning activity not available via other (satellite, meteorological) techniques. The most interesting characteristics to be extracted in an inversion procedure are the rates of vertical charge moment change (and their temporal variations) in the major global lightning “chimneys”. The success of such a procedure depends critically on the accuracy of the propagation theory (used to carry out “direct” calculations for the inversion) and the quality of experimental material. Due to the nature of the problem, both factors - the accuracy and the quality - can only be estimated indirectly, which requires specific approaches to assure that the estimates are realistic and more importantly, that the factors could be improved. For the first factor, simulations show that the widely exploited theory of propagation in a uniform (spherically symmetrical) waveguide provides unacceptable (up to several tens of percent) errors when used to extract the rates of charge moment change in the major “chimneys”. A comparative analysis carried out on the basis of a more accurate two-dimensional telegraph equation (TDTE) technique shows that the above inaccuracy results mainly from neglecting the major non-uniformity of the Earth-ionosphere waveguide due to the electrodynamic contrast between its day- and nighttime hemispheres. To estimate improve the quality of observations, several approaches are presented. Generally, the approaches are based on dividing the observation interval into shorter (10-sec) segments and collecting their Fourier transforms via an “accept/reject” criterion dependent on both the statistics of the segments’ energy contents within the given interval and the observational history. Such a procedure allows the removal of “bad” segments contaminated by either cultural interference or local lightning activity, instead of rejecting the whole interval as a “bad” one. Several criteria are presented, their efficiencies demonstrated, compared, and tested on actual SR observations from various stations for various seasons and times; the effect of using improved (rectified) SR data in an actual multi-station inversion procedure is demonstrated.

  16. Glutathione peroxidase mimic ebselen improves glucose-stimulated insulin secretion in murine islets.

    Glutathione peroxidase (GPX) mimic ebselen and superoxide dismutase (SOD) mimic copper diisopropylsalicylate (CuDIPs) were used to rescue impaired glucose-stimulated insulin secretion (GSIS) in islets of GPX1 and(or) SOD1-knockout mice. Ebselen improved GSIS in islets of all four tested genotypes. The rescue in the GPX1 knockout resulted from a coordinated transcriptional regulation of four key GSIS regulators and was mediated by the peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α)-mediated signaling pathways. In contrast, CuDIPs improved GSIS only in the SOD1 knockout and suppressed gene expression of the PGC-1α pathway. Islets from the GPX1 and(or) SOD1 knockout mice provided metabolically controlled intracellular hydrogen peroxide (H2O2) and superoxide conditions for the present study to avoid confounding effects. Bioinformatics analyses of gene promoters and expression profiles guided the search for upstream signaling pathways to link the ebselen-initiated H2O2 scavenging to downstream key events of GSIS. The RNA interference was applied to prove PGC-1α as the main mediator for that link. Our study revealed a novel metabolic use and clinical potential of ebselen in rescuing GSIS in the GPX1-deficient islets and mice, along with distinct differences between the GPX and SOD mimics in this regard. These findings highlight the necessities and opportunities of discretional applications of various antioxidant enzyme mimics in treating insulin secretion disorders.

    Y-chromosomal haplogroups are sets of ancestrally related paternal lineages, traditionally assigned by the use of Y-chromosomal single nucleotide polymorphism (Y-SNP) markers. An increasingly popular and a less labor-intensive alternative approach has been Y-chromosomal haplogroup assignment based on already available Y-STR data using a variety of different algorithms. In the present study, such in silico haplogroup assignments were made based on 23-loci Y-STR data for 100 unrelated male individuals from the Tuzla Canton, Bosnia and Herzegovina (B&H) using the following four different algorithms: Whit Athey's Haplogroup Predictor, Jim Cullen's World Haplogroup & Haplogroup-I Subclade Predictor, Vadim Urasin's YPredictor and the NevGen Y-DNA Haplogroup Predictor. Prior in-house assessment of these four different algorithms using a previously published dataset (n=132) from B&H with both Y-STR (12-loci) and Y-SNP data suggested haplogroup misassignment rates between 0.76% and 3.02%. Subsequent analyses with the Tuzla Canton population sample revealed only a few differences in the individual haplogroup assignments when using different algorithms. Nevertheless, the resultant Y-chromosomal haplogroup distribution by each method was very similar, where the most prevalent haplogroups observed were I, R and E with their sublineages I2a, R1a and E1b1b, respectively, which is also in accordance with the previously published Y-SNP data for the B&H population. In conclusion, results presented herein not only constitute a concordance study on the four most popular haplogroup assignment algorithms, but they also give a deeper insight into the inter-population differentiation in B&H on the basis of Y haplogroups for the first time.

    automatic email alerts sent upon achieving them. During 1-week training at home, automatic notifications were received on 4.4 days (SD 1.8). Although the high intensity interval training regimen was feasible on-site, it was difficult for self- and remote management. Opportunistic leg exercise under the desk, while working with a computer, and training in bed while viewing television were less intensive than dosed exercise bouts, but allowed prolonged leg mobilization of 73.7 minutes/day (SD 29.7). This study demonstrated the feasibility of self-control exercise training on-site, which was accompanied by online monitoring, electronic recording, personalization of exercise doses, and automatic reporting of adherence. The results suggest that this technology and its applications are useful for the delivery of Web-based exercise rehabilitation and cardiac training programs at the point of care. ©Vadim N Dedov, Irina V Dedova.

    conducted the research. The Chandra observation of Venus was also a technological tour de force. The angular separation of Venus from the Sun, as seen from Earth, never exceeds 48 degrees. This relative proximity has prevented star trackers and cameras on other X-ray astronomy satellites from locking onto guide stars and pointing steadily in the direction of Venus to perform such an observation. Venus was observed on Jan. 10, 2001, with the Advanced CCD Imaging Spectrometer (ACIS) detector plus the Low Energy Transmission Grating and on Jan. 13, 2001, with the ACIS alone. Other members of the team were Vadim Burwitz and Jakob Engelhauser, Max Planck Institute; Carey Lisse, University of Maryland, College Park; and Scott Wolk, Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass. These results were presented at this week's "New Visions of X-ray universe in the XMM-Newton and Chandra Era" symposium in Noordwijk, Netherlands. The Low Energy Transmission Grating was built by the Space Research Organization of the Netherlands and the Max Planck Institute, and the ACIS instrument was developed for NASA by The Pennsylvania State University, University Park, and the Massachusetts Institute of Technology (MIT), Cambridge.

  4. Never Before Seen: Two Supermassive Black Holes in Same Galaxy

    NASA Astrophysics Data System (ADS)

    is a prime example of a massive galaxy in which stars are forming at an exceptionally rapid rate due to a recent collision and subsequent merger of two smaller galaxies. Because of the large amount of dust and gas in such galaxies, it is difficult to peer deep into their central regions with optical telescopes. However, X-rays emanating from the galactic core can penetrate the veil of gas and dust. NGC 6240 Optical & X-ray Comparison of NGC 6240 "The detection of a binary black hole supports the idea that black holes can grow to enormous masses in the centers of galaxies by merging with other black holes," said Komossa. "This is important for understanding how galaxies form and evolve," she said. Over the course of the next few hundred million years, the two black holes in NGC 6240, which are about 3000 light years apart, will drift toward one another and merge to form an even larger supermassive black hole. Toward the end of this process an enormous burst of gravitational waves will be produced several hundred million years from now. These gravitational waves will spread through the universe and produce ripples in the fabric of space, which would appear as minute changes in the distance between any two points. NASA's planned space-based detector, LISA (Laser Interferometer Space Antenna), will search for gravitational waves from massive black-hole mergers. These events are estimated to occur several times each year in the observable universe. "This is the first time we see a binary black hole in action, the smoking gun for something that will become a major gravitational wave burst in the future," said Hasinger. Chandra observed NGC 6240 for 10.3 hours with the Advanced CCD Imaging Spectrometer (ACIS).

  6. Chandra Shows New Way to Measure Cosmic Distances

    Using NASA's Chandra X-ray Observatory, a team of scientists has attacked one of astronomy's oldest and thorniest problems, determining the distance to a cosmic object. Through measuring the distance to an X-ray source by observing the delay and smearing out of X-ray signals traversing 30,000 light years of interstellar gas and dust, Chandra "opened a new world," said Peter Predehl of the Max-Planck Institute, Garching, Germany, the lead author on a report to be published in the European journal, Astronomy and Astrophysics. "Geometrical distance measurements are of particular importance for astronomy. Now we have a new method that works for distant sources," Predehl said. One of the most crucial pieces of information needed in astronomy is the distance to the stars and galaxies. They are also among the most difficult to obtain because, with rare exceptions, astronomers cannot measure distance directly and must use a variety of ingenious but uncertain techniques. This new method relies on the scattering of X-rays by interstellar dust grains between a source and the Earth. Although the scattering material is different, the dust produces a halo, much like the halo around a traffic light on a foggy night. "When the light switches from red to green (or vice versa), the halo around the light is also slightly delayed," Predehl explained. "No one would use this delay for determining the distance to the traffic light, of course, (the delay is only a few billionths of a second). But if the 'traffic light' is 30,000 light years away, the delay is on the order 15 minutes. Using the excellent and unprecedented resolution of the Chandra observatory, we can distinguish between light which was 30,000 years on its way and other light which needed only a few minutes more. " Other members of the team included Vadim Burwitz and Joachim Trumper, also of the Max-Planck Institute, and Frits Paerels of Columbia University, New York.

    issue of available EUV power from electrical discharge pinch plasmas and laser produced plasmas, including the roots of these requirements, the relevant plasma and radiation physics, and current state-of-the-art commercial technology. In the first paper of the cluster, Vadim Banine and Roel Moors of ASML in the Netherlands provide a detailed review of the required EUV power based on an economically viable throughput of one hundred 300 mm diameter wafers per hour, projected resist sensitivity, number of finite reflectivity multilayer coated surfaces and their collective spectral bandwidth, and a collection solid angle set by optical phase-space constraints and plasma source size. Thomas Krücken and his colleagues from Philips and the Fraunhofer Institute in Aachen present a theoretical model of radiation generation and transport based on model density and temperature profiles in an electrical discharge plasma, providing valuable insights into radiation physics and the limits to achievable power. Kenneth Fahy and his colleagues at UCD in Dublin and NIST in the US, in their paper, describe in detail atomic physics calculations of emission from relevant lines and unresolved transition arrays (UTAs) of candidate xenon and tin ions, each of which radiate strongly within the acceptance bandwidth of the multilayer coatings. The different elements, Xe and Sn, however, raise significantly different implications for source debris production and thus of requisite debris mitigation requirements. Björn Hannson and Hans Hertz of KTH University in Stockholm present a substantial review of laser produced plasmas for the EUV, including those based on liquid jet technologies, leading to a path of mass limited target material, and significant stand-off distance from the solid nozzle, which maximize EUV power generation while minimizing debris production. In addition to an extensive review of EUV source related literature, they describe experiments with laser irradiated droplets and

    discovered acetamide (CH3CONH2), which can be formed when a previously-discovered neutral molecule called formamide (HCONH2) combines with radicals such as CH2 and CH3, also previously discovered. Acetamide is particularly interesting because it contains a peptide bond which is the means for linking amino acids together to form proteins. Once interstellar molecules are ejected from dust grains into the gas phase, presumably by shock waves, they are free to rotate end-over-end. As gas molecules change their rotational modes, they can emit or absorb radiation at precise radio frequencies, called transitions, that are unique to each type of molecule. By detecting several rotational transitions, astronomers can unambiguously identify a specific interstellar molecule. "It is important to note that likely interstellar molecule candidates are first studied in gas-phase laboratory experiments so that transition frequencies are known in advance of an interstellar experiment," said Frank Lovas of the National Institute of Standards and Technology. Along the line of sight from the interstellar cloud to the telescope, thousands of billions of molecules undergo the exact same transition, producing a signal strong enough to be detected by sensitive equipment. For this type of work, the GBT is the world's most sensitive tool that can be accurately pointed and track astronomical objects. In addition to Hollis, Jewell, Remijan, and Lovas, the research team included Lewis Snyder of the University of Illinois; Harald Mollendal of the University of Oslo, Norway; Vadim Ilyushin of the Institute of Radio Astronomy of the National Academy of Sciences of the Ukraine; and Isabell Kleiner of the Universite Paris, France. The astronomers' reports on their results appeared in 8 separate editions of the Astrophysical Journal.

    promoting the elucidation of the molecular structures of drug targets in MTB, and are consequently markedly useful for the design of new, promising antituberculous drugs using QSAR techniques. In this issue, we review the following areas. Firstly, Dr. Li M. Fu reviews the perspective that combines machine learning and genomics for drug discovery in tuberculosis, in relation to the problem that the exhaustive search for useful drug targets over the entire MTB genome would not be as productive as expected in practice [1]. Secondly, the review article by Drs. R. S. Chauhan. S. K. Chanumolu, C. Rout, and R. Shrivastava focuses on analysis of the current state of MTB genomic resources, host-pathogen interaction studies in the context of mycobacterial persistence, and drug target discovery based on the utilization of computational tools and metabolic network analyses [2]. Thirdly, Drs. Daria Bottai, Agnese Serafini, Alessandro Cascioferro, Roland Brosch, and Riccardo Manganelli review the current knowledge on MTB T7SS/ESX secretion systems and their impact on MTB physiology and virulence, and the possible approaches to develop T7SS/ESX inhibitors [3]. Fourthly, Drs. E. Jeffrey North, Mary Jackson, and Richard E. Lee review and analyze new and emerging inhibitors of the mycolic acid biosynthetic pathway, including mycobacterial enzymes for fatty acid synthesis, mycolic acid-modifying enzymes, fatty acid-activating and -condensing enzymes, transporters, and transferases, that have been discovered in the post-genomic era of tuberculosis drug discovery [4]. Fifthly, Drs. Katarina Mikusova, Vadim Makarov, and Joao Neres review the mycobacterial enzyme DprE1, which catalyzes a unique epimerization reaction in the biosynthesis of decaprenylphosphoryl arabinose, a single donor of the arabinosyl residue for the build-up of arabinans, one of the mycobacterial cell wall components, as an important drug target especially for the development of benzothiazinones [5]. Sixthly, I review the

    him, he is widely quoted as saying ``My God, it worked!'' Following the war, Ken, along with Hans Bethe and other scientists, sent a letter to the President strongly advocating only non-military use of nuclear research. Ken and family returned to Cornell University and Ithaca, where he remained, except for sabbatical periods, for the rest of his life. He spent the next years studying cosmic rays and the showers of particles produced by them in the atmosphere and various absorbers. An array of scintillators atop Cornell buildings allowed both the direction and intensity of air showers to be determined. Detectors 600m underground, in a salt mine near Ithaca, detected only mesons with sufficient energy to penetrate so much material. In summers, detectors at a range of altitudes from the bottom to the top of Mount Evans (Colorado) provided altitudinal studies of cosmic-ray air showers and attracted an article in Life magazine. In early 1966, Ken realized that cosmic ray protons at energies above 6 x 1019 eV will interact significantly with the extremely low energy photons of the Cosmic Microwave Background, which had recently been discovered. If the sources of such extremely high-energy cosmic rays are at cosmological distances, this interaction should cause a sharp cutoff in the cosmic ray spectrum. The effect has been named the GZK cutoff after Greisen's paper and an independent, slightly later paper by Georgi Zatsepin and Vadim Kuzmin. Ken's paper also predicted a small dip in the cosmic-ray spectrum at energies of 1018-1020 eV, due to pair production by the thermal photons. Cosmic rays of such high energies cause the Earth's atmosphere to fluoresce, making the Earth itself into a detector. Beginning in the early 1960s, Ken and his group developed instruments to measure this fluorescence and implemented them, in a "fly's eye" configuration, in the hills surrounding Ithaca. The concept was taken around 1970 to the clearer skies of Utah, where a University of Utah group
