A shortened treatment with rosemary tea (rosmarinus officinalis) instead of glucose in patients with diabetes mellitus type 2 (TSD)

BLANCA PATRICIA LAZALDE RAMOS (2019)

Background

Rosemary leaves powder has been reported to reduce in a dose-dependent manner, glucose levels, lipid profile and lipid peroxidation in humans. However, patients should ingest high doses of powder contained in capsules. This formulation constitutes the intake of 10 capsules per day, so the active metabolite must first, be released and then absorbed (for which, rosemary leaf powder must be mixed with gastric juice).

Aim

Evaluate whether a shortened dose and time of treatment as well as the pharmaceutical presentation in rosemary tea (Rosmarinus officinalis) instead of powder have a therapeutic effect in the treatment of T2D.

Method

The complementary therapy with Rosemary tea (2g/1 litre of water per day) were evaluate on resistance to insulin, oxidative stress, biochemical parameters and anthropometric measurements in forty patients T2D under treatment with metformin and/or glibenclamide afther giving your authorization through informed consent.

Mass-metallicity relation explored with CALIFA: I. Is there a dependence on the star-formation rate?⋆

Fernando Fabián Rosales Ortega (2013)

We studied the global and local M-Z relation based on the first data available from the CALIFA survey (150 galaxies). This survey provides integral field spectroscopy of the complete optical extent of each galaxy (up to 2−3 effective radii), with a resolution high enough to separate individual HII regions and/or aggregations. About 3000 individual HII regions have been detected. The spectra cover the wavelength range between [OII]3727 and [SII]6731, with a sufficient signal-to-noise ratio to derive the oxygen abundance and star-formation rate associated with each region. In addition, we computed the integrated and spatially resolved stellar masses (and surface densities) based on SDSS photometric data. We explore the relations between the stellar mass, oxygen abundance and star-formation rate using this dataset. We derive a tight relation between the integrated stellar mass and the gas-phase abundance, with a dispersion lower than the one already reported in the literature (σ∆log(o/H) = 0.07 dex). Indeed, this dispersion is only slightly higher than the typical error derived for our oxygen abundances. However, we found no secondary relation with the star-formation rate other than the one induced by the primary relation of this quantity with the stellar mass. The analysis for our sample of ~3000 individual HII regions confirms (i) a local mass-metallicity relation and (ii) the lack of a secondary relation with the star-formation rate. The same analysis was performed with similar results for the specific star-formation rate. Our results agree with the scenario in which gas recycling in galaxies, both locally and globally, is much faster than other typical timescales, such like that of gas accretion by inflow and/or metal loss due to outflows. In essence, late-type/disk-dominated galaxies seem to be in a quasi-steady situation, with a behavior similar to the one expected from an instantaneous recycling/closed-box model.

A Spitzer-IRS Spectroscopic atlas of early-type galaxies in the Revised Shapley-Ames Catalog

OLGA MERCEDES VEGA CASANOVA (2013)

We produce an atlas of homogeneously reduced and calibrated low resolution IRS spectra of the nuclear regions of nearby early-type galaxies (i.e. Es and S0s, ETGs), in order to build a reference sample in the mid-infrared window. From the Spitzer Heritage Archive we extract ETGs in the Revised Shapley-Ames Catalog of Bright Galaxies having an IRS SL and/or LL spectrum. We recover 91 spectra out of 363 galaxies classified as ETGs in the catalog: 56 E (E0-E6), 8 mixed E/S0+S0/E, 27 S0 (both normal and barred - SB0) plus mixed types SB0/Sa+SB0/SBa. For each galaxy, we provide the fully reduced and calibrated spectrum, the intensity of nebular and molecular emission lines as well as of the Polycyclic Aromatic Hydrocarbons (PAHs) after a template spectrum of a passively evolving ETG has been subtracted. Spectra are classified into five mid-infrared classes, ranging from AGN (class-4) and star forming nuclei (class-3), transition class-2 (with PAHs) and class-1 (no-PAHs) to passively evolving nuclei (class-0). A demographic study of mid-infrared spectra shows that Es are significantly more passive than S0s:46⁺¹¹₋₁₀% of Es and 20⁺¹¹₋₇ % of S0s have a spectrum of class-0. Emission lines are revealed in 64⁺¹²₋₆ % of ETGs. The H₂S(1) line is found with similar rate in Es (34⁺¹⁰₋₈ %) and in S0s (51⁺¹⁵₋₁₂%). PAHs are detected in 47⁺⁸₋₇% of ETGs, but only 9⁺⁴₋₃% have PAHs ratios typical of star forming galaxies. Several indicators, such as peculiar morphologies and kinematics, dust–lane irregular shape, radio and X-ray properties, suggest that mid-infrared spectral classes are connected to phases of accretion/feedback phenomena occurring in the nuclei of ETGs.

SOURCE PARAMETERS OF THE ORIZABA EARTHQUAKE OF AUGUST 28, 1973

Shri Krishna Singh (1976)

The theory and method by which the source parameters of an earthquake can be derived from seismic signals in reviewed. 11 P-wave spectra (short and long period records for each station) are averaged and combined with 11G2 wave spectra to define the average source spectrum of the Orizaba earthquake between periods of 200 sec and 0.5 sec. the seismic moment of this () earthquake is determined as 4.8dyne cm. The corner frequency is 0.1 cps, from wich the source radius is estimated to have been 13 km, with a stress drop of 95 bars.
