  Title Physical, Thermal and Spectral Properties of Biofield Treated 3-Nitroacetophenone Type Journal Article
  Year 2015 Publication Science Journal of Analytical Chemistry Abbreviated Journal  
  Volume 3 Issue 6 Pages 71-79  
  Keywords X-Ray Diffraction, Thermal Analysis, Laser Particle Size Analysis, Surface Area Analysis, Fourier Transform Infrared Spectroscopy, Ultra Violet-Visible Spectroscopy  
  Abstract (up) 3-Nitroacetophenone (3-NAP) is an organic compound used as an intermediate for the synthesis of pharmaceutical agents. The aim of this study was to evaluate the impact of biofield energy treatment on the physical, thermal and spectral properties of 3-NAP. The study was performed in two groups i.e. control and treated. The control group remained as untreated, and the treated group received Mr. Trivedi’s biofield energy treatment. The control and treated 3-NAP samples were further characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), laser particle size analyzer, surface area analyzer, Fourier transform infrared (FT-IR) spectroscopy, and ultra violet-visible spectroscopy (UV-vis) analysis. The XRD analysis showed decrease in crystallite size of treated 3-NAP by 20.27% as compared to the control sample. However, the XRD peaks of treated sample showed an increase in intensity as compared to the control. The DSC result showed a slight increase in melting temperature of treated 3-NAP (80.75ºC) with respect to the control (79.39ºC). The latent heat of fusion of treated 3-NAP was changed by 16.28% as compared to the control sample. The TGA analysis showed an increase in onset temperature of treated sample (192ºC) as compared to the control sample (182ºC). Further, the maximum thermal decomposition temperature (Tmax) of treated 3-NAP was increased as compared to the control. This showed the increase in thermal stability of treated 3-NAP with respect to control. The treated 3-NAP showed an increase in average particle size (d50) by 27.6% along with an increase in size exhibited by 99% of particles (d99) by 4.9% as compared to the control. Brunauer-Emmett-Teller (BET) analysis showed a substantial decrease in surface area by 24.6% with respect to the control. The FT-IR analysis showed an emergence of peak at 1558 cm-1 in treated 3-NAP sample as compared to the control. Nevertheless, the UV spectral analysis of treated 3-NAP showed no alterations in absorption peaks as compared to the control. Altogether, the result showed that biofield energy treatment has altered the physical, thermal and spectral properties of treated 3-NAP as compared to the control.

  Abstract (up) 4-Bromoacetophenone is an acetophenone derivative known for its usefulness in organic coupling reactions and various biological applications. The aim of the study was to evaluate the impact of biofield energy treatment on 4- bromoacetophenone using various analytical methods. The material is divided into two groups for this study i.e. control and treated. The control group remained as untreated and the treated group was subjected to Mr. Trivedi’s biofield energy treatment. Then, both the samples were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), gas chromatography-mass spectrometry (GC-MS), and UV-visible spectrometry (UV-vis). The XRD study revealed that the crystallite size of treated 4-bromoacetophenone was decreased significantly to 16.69% with decreased intensity as compared to the control. The thermal studies revealed that the slight change was observed in the melting point and latent heat of fusion (ΔH) of biofield energy treated sample as compared to the control. Maximum degradation temperature (Tmax) of treated 4-bromoacetophenone was decreased by 7.26% as compared to the control (169.89°C→157.54°C). The FT-IR spectra showed that the C=O stretching frequency at 1670 cm-1 was shifted to higher frequency region (1672 in T1 and 1685 cm-1 in T2, in two treated samples for FT-IR) after biofield energy treatment. Moreover, the GC-MS data revealed that the isotopic abundance ratio of either 13C/12C or 2H/1H (PM+1)/PM was decreased up to 9.12% in T2 sample whereas increased slightly up to 3.83% in T3 sample. However, the isotopic abundance ratio of either 81Br/79Br or 18O/16O (PM+2)/PM of treated 4-bromoacetophenone was decreased from 0.10% to 1.62% (where PM-primary mass of the molecule, (PM+1) and (PM+2) are isotopic mass of the molecule). The UV spectra showed the similar electronic behavior like absorption maximum in control and treated samples. Overall, the experimental results suggest that Mr. Trivedi’s biofield energy treatment has significant effect on the physical, thermal, and spectral properties of 4-bromoacetophenone.

  Title Rhopalotricha, a New Subgenus of the Fern Genus Lastreopsis (Dryopteridaceae) Type Journal Article
  Year 2015 Publication American Fern Journal Abbreviated Journal  
  Volume 105 Issue 1 Pages 20-30  
  Keywords  
  Abstract (up) A new subgenus of Lastreopsis, subg. Rhopalotricha, is here described based on the results of our recent phylogenetic analyses. Its species differ from others in the genus by having a distinctive type of hair within the grooves of the rachises and costae adaxially. These are 1–3(–4)-celled and clavate, whereas the remainders of the species in the genus have hairs that are 3–12-celled and non-clavate. Subgenus Rhopalotricha also differs by having spores with broadly folded perispores with echinulate surfaces (vs. tuberculate or spiny, and with smooth surfaces). Subgenus Rhopalotricha occurs in the Neotropics, islands of the southwestern Pacific (Samoa, Fiji, and Vanuatu), New Zealand, and Australia. A key is provided to distinguish the species, each of which is treated with synonymy, description, geographic distribution by country, elevation ranges, and discussions. Lectotypes are also designated for Dryopteris amplissima var. subeffusa, Aspidium macrum Fée, and Aspidium latissimum Fée.

  Title Dissociation in individuals denying trauma exposure: findings from two samples Type Journal Article
  Year 2015 Publication The Journal of Nervous and Mental Disease Abbreviated Journal J Nerv Ment Dis  
  Volume 203 Issue 6 Pages 439-442  
  Keywords Adult; Affective Symptoms/*psychology; Aged; Dissociative Disorders/*psychology; Female; Humans; Male; Middle Aged; Young Adult  
  Abstract (up) A number of studies suggest that dissociation is reliably related to trauma exposure, and that inadequate regulation of posttraumatic distress may be a significant factor. We examined whether affect dysregulation predicts dissociation in those denying any lifetime exposure to trauma. These relationships were evaluated in a general population sample and a second sample of nontraumatized university students. In the first study, multivariate analyses indicated that, along with gender, affect dysregulation was a relatively strong predictor, accounting for 27% of the variance in dissociation. In the replication study, dissociation was associated with affect dysregulation, but not gender. Affect dysregulation seems to predict dissociative symptomatology in nontraumatized individuals. It is hypothesized that emotional distress, whether from trauma or other etiologies, motivates dissociation to the extent that it challenges the individual's compromised capacity for affect regulation. Treatment implications may include the potential helpfulness of interventions that increase emotion regulation skills.

  Title Trauma-Related Altered States of Consciousness (TRASC) and Functional Impairment I: Prospective Study in Acutely Traumatized Persons Type Journal Article
  Year 2015 Publication Journal of Trauma & Dissociation : the Official Journal of the International Society for the Study of Dissociation (ISSD) Abbreviated Journal J Trauma Dissociation  
  Volume 16 Issue 5 Pages 500-519  
  Keywords 4-D model; childhood abuse and neglect; dissociation; posttraumatic stress disorder; trauma-related altered states of consciousness  
  Abstract (up) A theoretical framework referred to as a 4-D model has been described for classifying posttraumatic stress symptoms into those potentially occurring within normal waking consciousness (NWC) versus those thought to intrinsically exemplify dissociative experiences, specifically, trauma-related altered states of consciousness (TRASC). As a further test of this theoretical distinction, this prospective study evaluated whether TRASC and NWC forms of distress incrementally and prospectively predicted functional impairment at 6 and 12 weeks following presentation at hospital emergency departments in the acute aftermath of traumatic events in 180 persons. Establishing the clinical significance of both TRASC and NWC-distress symptoms, we found that 6-week markers of TRASC and NWC-distress independently predicted 12-week self-reported levels of social and occupational impairment. We also observed broad support for various predictions of the 4-D model except that, in contrast with hypotheses, childhood trauma history was generally more strongly correlated with symptoms of NWC-distress than with TRASC. Future research directions are discussed.

  Title Quantification of histone modifications by parallel-reaction monitoring: a method validation Type Journal Article
  Year 2015 Publication Abbreviated Journal Anal Chem  
  Volume 87 Issue 19 Pages 10006-10014  
  Keywords  
  Abstract (up) Abnormal epigenetic reprogramming is one of the major causes leading to irregular gene expression and regulatory pathway perturbations, in the cells, resulting in unhealthy cell development or diseases. Accurate measurements of these changes of epigenetic modifications, especially the complex histone modifications, are very important, and the methods for these measurements are not trivial. By following our previous introduction of PRM to targeting histone modifications (Tang, H.; Fang, H.; Yin, E.; Brasier, A. R.; Sowers, L. C.; Zhang, K. Multiplexed parallel reaction monitoring targeting histone modifications on the QExactive mass spectrometer. Anal. Chem. 2014, 86 (11), 5526-34), herein we validated this method by varying the protein/trypsin ratios via serial dilutions. Our data demonstrated that PRM with SILAC histones as the internal standards allowed reproducible measurements of histone H3/H4 acetylation and methylation in the samples whose histone contents differ at least one-order of magnitude. The method was further validated by histones isolated from histone H3 K36 trimethyltransferase SETD2 knockout mouse embryonic fibroblasts (MEF) cells. Furthermore, histone acetylation and methylation in human neural stem cells (hNSC) treated with ascorbic acid phosphate (AAP) were measured by this method, revealing that H3 K36 trimethylation was significantly down-regulated by 6 days of treatment with vitamin C.

  Title Looking beyond parks: the conservation value of unprotected areas for hornbills in Arunachal Pradesh, Eastern Himalaya Type Journal Article
  Year 2015 Publication Abbreviated Journal Oryx  
  Volume 49 Issue 2 Pages 303-311  
  Keywords  
  Abstract (up) AbstractThe loss of tropical forests and associated biodiversity is a global concern. Conservation efforts in tropical countries such as India have mostly focused on state-administered protected areas despite the existence of vast tracts of forest outside these areas. We studied hornbills (Bucerotidae), an ecologically important vertebrate group and a flagship for tropical forest conservation, to assess the importance of forests outside protected areas in Arunachal Pradesh, north-east India. We conducted a state-wide survey to record encounters with hornbills in seven protected areas, six state-managed reserved forests and six community-managed unclassed forests. We estimated the density of hornbills in one protected area, four reserved forests and two unclassed forests in eastern Arunachal Pradesh. The state-wide survey showed that the mean rate of encounter of rufous-necked hornbills Aceros nipalensis was four times higher in protected areas than in reserved forests and 22 times higher in protected areas than in unclassed forests. The mean rate of encounter of wreathed hornbills Rhyticeros undulatus was twice as high in protected areas as in reserved forests and eight times higher in protected areas than in unclassed forests. The densities of rufous-necked hornbill were higher inside protected areas, whereas the densities of great hornbill Buceros bicornis and wreathed hornbill were similar inside and outside protected areas. Key informant surveys revealed possible extirpation of some hornbill species at sites in two protected areas and three unclassed forests. These results highlight a paradoxical situation where individual populations of hornbills are being lost even in some legally protected habitat, whereas they continue to persist over most of the landscape. Better protection within protected areas and creative community-based conservation efforts elsewhere are necessary to maintain hornbill populations in this biodiversity-rich region.
