Loopy Constraints on Leptophilic Dark Matter and Internal Bremsstrahlung

A sharp and spatially extended peak in an astrophysical gamma ray spectrum would provide very strong evidence for the existence of dark matter (DM), given that there are no known astrophysical processes that could mimic such a signal. From the particle physics perspective, perhaps the simplest explanation for a gamma ray peak is internal bremsstrahlung in DM annihilation through a charged t-channel mediator eta close in mass to the DM particle chi. Since DM annihilation to quarks is already tightly constrained in this scenario, we focus here on the leptophilic case. We compute the electromagnetic anapole and dipole moments that DM acquires at 1-loop, and we find an interesting enhancement of these moments if the DM particle and the mediator are close in mass. We constrain the DM anapole and dipole moments using direct detection data, and then translate these limits into bounds on the DM annihilation cross section. Our bounds are highly competitive with those from astrophysical gamma ray searches. In the second part of the paper, we derive complementary constraints on internal bremsstrahlung in DM annihilation using LEP mono-photon data, measurements of the anomalous magnetic moments of the electron and the muon, and searches for lepton flavor violation. We also comment on the impact of the internal bremsstrahlung scenario on the hyperfine splitting of true muonium.Comment: 16 pages, 16 figures, Journal accepted version, read it

Improving Electro-Weak Fits with TeV-scale Sterile Neutrinos

We study the impact of TeV-scale sterile neutrinos on electro-weak precision observables and lepton number and flavour violating decays in the framework of a type-I see-saw extension of the Standard Model. At tree level sterile neutrinos manifest themselves via non-unitarity of the PMNS matrix and at one-loop level they modify the oblique radiative corrections. We derive explicit formulae for the S,T,U parameters in terms of the neutrino masses and mixings and perform a numerical fit to the electro-weak observables. We find regions of parameter space with a sizable active-sterile mixing which provide a better over-all fit compared to the case where the mixing is negligible. Specifically we find improvements of the invisible Z-decay width, the charged-to-neutral-current ratio for neutrino scattering experiments and of the deviation of the W boson mass from the theoretical expectation.Comment: 16 pages, 17 figures, Journal accepted versio

Evaluation of the Impact of the Trivedi Effect® -Energy of Consciousness on the Structure and Isotopic Abundance Ratio of Magnesium Gluconate Using LC-MS and NMR Spectroscopy

Magnesium gluconate is a classical pharmaceutical/nutraceutical compound used as a magnesium ion source for the prevention and treatment of hypomagnesemia. The present study was aimed to investigate the effect of The Trivedi Effect® - Energy of Consciousness Healing Treatment (Biofield Energy Healing Treatment) on magnesium gluconate for the change in the structural properties and isotopic abundance ratio (PM+1/PM and PM+2/PM) using LC-MS and NMR spectroscopy. Magnesium gluconate was divided into two parts – one part was control, and another part was treated with The Trivedi Effect® - Biofield Energy Healing Treatment remotely by twenty renowned Biofield Energy Healers and defined as The Trivedi Effect® Treated sample. The LC-MS analysis of both the control and treated samples indicated the presence of mass of the protonated magnesium gluconate at m/z 415 at the retention time of 1.52 min and fragmentation pattern of the both sample were almost similar. The relative peak intensities of the fragment ions were significantly changed in the treated sample compared with the control sample. The proton and carbon signals for CH, CH2 and CO groups in the proton and carbon NMR spectra were observed almost similar for the control and the treated samples. The percentage change in the isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 17O/16O or 25Mg/24Mg) was significantly decreased in the treated sample by 17.51% compared with the control sample. Consequently, the isotopic abundance ratio of PM+2/PM (18O/16O or 26Mg/24Mg) in the treated sample was significantly increased by 79.44% compared to the control sample. Briefly, 13C, 2H, 17O, and 25Mg contributions from (C12H23MgO14)+ to m/z 416; 18O and 26Mg contributions from (C12H23MgO14)+ to m/z 417 in treated sample were significantly altered compared with the control sample. Thus, The Trivedi Effect® Treated magnesium gluconate might be supportive to design the novel potent enzyme inhibitors using its kinetic isotope effects. Consequently, The Trivedi Effect® Treated magnesium gluconate would be valuable for designing better pharmaceutical and/or nutraceutical formulations through its changed physicochemical and thermal properties, which might be providing better therapeutic response against various diseases such as diabetes mellitus, allergy, aging, inflammatory diseases, immunological disorders, and other chronic infections.

Evaluation of the Physicochemical, Structural, Thermal, and Behavioral Properties of the Energy of Consciousness Healing Treated Zinc Chloride

Zinc chloride is a source of zinc used in various pharmaceutical/nutraceutical formulations. The objective of the current study was to investigate the impact of The Trivedi Effect® - Energy of Consciousness Healing Treatment (Biofield Energy Treatment) on physical, structural, thermal, and behavioral properties of zinc chloride using PXRD, PSD, FT-IR, UV-vis, and DSC analysis. Zinc chloride was divided into two parts – one part was control, while another part was treated with The Trivedi Effect® remotely by twenty renowned Biofield Energy Healers and defined as The Trivedi Effect® Treated sample. A significant alteration of the crystallite size and relative intensities of the PXRD peaks was observed in The Trivedi Effect® treated sample compared with the control sample. The average crystallite size of the treated sample was significantly increased by 23.18% compared with the control sample. The particle size values at d10, d50, and d90 values were significantly decreased by 3.70%, 4.13%, and 6.13%, respectively in the treated sample compared with the control sample. Therefore, the surface area of the treated sample was increased by 4.21% compared with the control sample. The FT-IR spectroscopic analysis revealed that Zn-Cl stretching in the control sample was found at 512 cm-1, whereas it was significantly shifted upward to 520 cm-1 in the treated sample. The UV-vis analysis exhibited that wavelength of the maximum absorbance (λmax) of the control and treated samples were at 197.6 nm and 197.1 nm, respectively. The DSC analysis exhibited that the melting temperature was decreased by 0.22%, while decomposition temperature was increased by 2.56% in the treated sample compared to the control sample. The latent heat of fusion of the treated sample (320.44 J/g) was significantly decreased by 16.70% compared with the control sample (284.67 J/g). Similarly, the enthalpy of decomposition of the treated sample (952.53 J/g) was significantly increased by 122.61% compared with the control sample (427.90 J/g). Thus, the results indicated that the thermal stability of the treated zinc chloride was improved compared with the control sample. The current study anticipated that The Trivedi Effect® - Energy of Consciousness Healing Treatment might lead to produce a thermally stable new polymorphic form of zinc chloride, which would be more soluble and bioavailable compared with the untreated compound. Hence, the treated zinc chloride would be very useful to design better nutraceutical/pharmaceutical formulations that might offer better therapeutic response against inflammatory diseases, immunological disorders, aging, stress, cancer, etc. https://www.trivedieffect.com/science/evaluation-of-the-physicochemical-structural-thermal-and-behavioral-properties-of-the-energy-of-consciousness-healing-treated-zinc-chloride http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=217&doi=10.11648/j.bio.20170502.1

Expression profiling of in vivo ductal carcinoma in situ progression models identified B cell lymphoma-9 as a molecular driver of breast cancer invasion

Abstract Introduction There are an estimated 60,000 new cases of ductal carcinoma in situ (DCIS) each year. A lack of understanding in DCIS pathobiology has led to overtreatment of more than half of patients. We profiled the temporal molecular changes during DCIS transition to invasive ductal carcinoma (IDC) using in vivo DCIS progression models. These studies identified B cell lymphoma-9 (BCL9) as a potential molecular driver of early invasion. BCL9 is a newly found co-activator of Wnt-stimulated β-catenin-mediated transcription. BCL9 has been shown to promote progression of multiple myeloma and colon carcinoma. However BCL9 role in breast cancer had not been previously recognized. Methods Microarray and RNA sequencing were utilized to characterize the sequential changes in mRNA expression during DCIS invasive transition. BCL9-shRNA knockdown was performed to assess the role of BCL9 in in vivo invasion, epithelial-mesenchymal transition (EMT) and canonical Wnt-signaling. Immunofluorescence of 28 patient samples was used to assess a correlation between the expression of BCL9 and biomarkers of high risk DCIS. The cancer genome atlas data were analyzed to assess the status of BCL9 gene alterations in breast cancers. Results Analysis of BCL9, by RNA and protein showed BCL9 up-regulation to be associated with DCIS transition to IDC. Analysis of patient DCIS revealed a significant correlation between high nuclear BCL9 and pathologic characteristics associated with DCIS recurrence: Estrogen receptor (ER) and progesterone receptor (PR) negative, high nuclear grade, and high human epidermal growth factor receptor2 (HER2). In vivo silencing of BCL9 resulted in the inhibition of DCIS invasion and reversal of EMT. Analysis of the TCGA data showed BCL9 to be altered in 26 % of breast cancers. This is a significant alteration when compared to HER2 (ERBB2) gene (19 %) and estrogen receptor (ESR1) gene (8 %). A significantly higher proportion of basal like invasive breast cancers compared to luminal breast cancers showed BCL9 amplification. Conclusion BCL9 is a molecular driver of DCIS invasive progression and may predispose to the development of basal like invasive breast cancers. As such, BCL9 has the potential to serve as a biomarker of high risk DCIS and as a therapeutic target for prevention of IDC
