Concept of Diabetic Neuropathy and its management in Ayurveda
Diabetes mellitus is a giant disease considered as one of the arch enemies of the mankind. The evidences at present suggest that incidence of Diabetes mellitus is raising among the general population. In Ayurveda, Diabetes mellitus closely resembles a disorder called Madhumeha, which is a subtype of Vataja Prameha. In Avarnjanya Madhumeha vitiated Kapha, Pitta and Meda causes Avarana to Vata that leads its aggravation causing diminution of vital Dhatus. This may lead to the complication of Madhumeha such as Diabetic Neuropathy. According to Ayurvedic principles there is involvement of Vata and Pitta Dosha in diabetic neuropathy. The drugs used conventionally are mostly for relief in the symptoms and moreover they have certain side effects. Many single drugs and Ayurvedic formulations are used in practice have significant effect on the symptoms of numbness, tingling, burning sensation and pain in the patients of diabetic neuropathy

Quality of Life determinants in women with breast cancer undergoing treatment with curative intent
BACKGROUND: The diagnosis of breast cancer and its subsequent treatment has significant impact on the woman's physical functioning, mental health and her well-being, and thereby causes substantial disruption to quality of life (QOL). Factors like patient education, spousal support and employment status, financial stability etc., have been found to influence QOL in the breast cancer patient. The present study attempts to identify the determinants of QOL in a cohort of Indian breast cancer patients. PATIENTS AND METHODS: Functional Assessment of Cancer Therapy-Breast (FACT-B) Version 4 Malayalam was used to assess quality of life in 502 breast cancer patients undergoing treatment with curative intent. The data on social, demographic, disease, treatment, and follow-up were collected from case records. Data was analysed using Analysis of Variance (ANOVA) and multinomial logistic regression. RESULTS: The mean age of the patients was 47.7 years with 44.6% of the women being pre-menopausal. The FACT-B mean score was 90.6 (Standard Deviation [SD] = 18.4). The mean scores of the subscales were – Physical well-being 19.6 (SD = 4.7), Social well-being 19.9 (SD = 5.3), Emotional well-being 14 (SD = 4.9), Functional well-being 13.0 (SD = 5.7), and the Breast subscale 23.8 (SD = 4.4). Younger women (<45 years), women having unmarried children, nodal and/or metastatic disease, and those currently undergoing active treatment showed significantly poorer QOL scores in the univariate analysis. However multivariate analysis indicated that the religion, stage, pain, spouse education, nodal status, and distance travelled to reach the treatment centre as indicative of patient QOL. CONCLUSION: QOL derangements are common in breast cancer patients necessitating the provisions for patient access to psychosocial services. However, because of the huge patient load, a screening process to identify those meriting intervention over the general population would be a viable solution
Direct observation by resonant tunneling of the B^+ level in a delta-doped silicon barrier
We observe a resonance in the conductance of silicon tunneling devices with a
delta-doped barrier. The position of the resonance indicates that it arises
from tunneling through the B^+ state of the boron atoms of the delta-layer.
Since the emitter Fermi level in our devices is a field-independent reference
energy, we are able to directly observe the diamagnetic shift of the B^+ level.
This is contrary to the situation in magneto-optical spectroscopy, where the
shift is absorbed in the measured ionization energy.Comment: submitted to PR
Theoretical Study on Superconductivity in Boron-Doped Diamond
We consider superconductivity in boron (B) doped diamond using a simplified
model for the valence band of diamond. We treat the effects of substitutional
disorder of B ions by the coherent potential approximation (CPA) and those of
the attractive force between holes by the ladder approximation under the
assumption of instantaneous interaction with the Debye cutoff. We thereby
calculate the quasiparticle life time, the evolution of the single-particle
spectra due to doping, and the effect of disorder on the superconducting
critical temperature . We in particular compare our results with those for
supercell calculations to see the role of disorder, which turns out to be of
crucial importance to .Comment: 9 pages, 13 figures, submitted to J. Phys. Soc. Jpn., Errors in

Evolution of magnetic polarons and spin-carrier interactions through the metal-insulator transition in EuGdO
Raman scattering studies as functions of temperature, magnetic field, and
Gd-substitution are used to investigate the evolution of magnetic polarons and
spin-carrier interactions through the metal-insulator transition in
EuGdO. These studies reveal a greater richness of phase behavior
than have been previously observed using transport measurements: a
spin-fluctuation-dominated paramagnetic (PM) phase regime for T T
T, a two-phase regime for T T in which magnetic polarons
develop and coexist with a remnant of the PM phase, and an inhomogeneous
ferromagnetic phase regime for T T
Assessment of conjunctival, episcleral and scleral thickness in healthy individuals using anterior segment optical coherence tomography
Purpose: To determine the thickness of the conjunctiva, episclera and sclera in healthy individuals using anterior segment optical coherence tomography (AS-OCT).Methods: We prospectively included 107 healthy individuals of different age groups (18-39 years, 40-54 years, 55-69 years and >= 70 years). For each eye, AS-OCT scans of four quadrants (temporal, nasal, superior and inferior) were acquired. The thickness of the conjunctiva, episclera and sclera was measured for each scan. In addition, the axial length of both eyes was measured, and general characteristics, including smoking, allergies and contact lens use, were collected.Results: The mean conjunctival thickness was significantly different between the nasal and superior quadrants (87 +/- 30 mu m vs. 77 +/- 16 mu m; p < 0.001), as well as the superior and inferior quadrants (77 +/- 16 mu m vs. 86 +/- 19 mu m; p = 0.001). The mean episcleral thickness was larger in the superior (174 +/- 54 mu m) and inferior (141 +/- 43 mu m) quadrants, compared to the nasal (83 +/- 38 mu m) and temporal quadrants (90 +/- 44 mu m). The mean scleral thickness of the inferior quadrant was the largest (596 +/- 64 mu m), followed by the nasal (567 +/- 76 mu m), temporal (516 +/- 67 mu m) and superior (467 +/- 52 mu m) quadrants (all p < 0.001). The averaged scleral thickness increased 0.96 mu m per age year (0.41-1.47 mu m, p < 0.001).Conclusions: This study provides an assessment of the thickness of scleral and adjacent superficial layers in healthy individuals determined on AS-OCT, which could enable future research into the use of AS-OCT in diseases affecting the anterior eye wall

The observation of the local - mode vibration, the two - mode behavior of the
LO phonons at large isotope concentration, as well as large line broadening in
LIH - D mixed crystals directly evidence strong additional phonon scattering
