Evaluation of Genotoxic and Cytotoxic Effects of Gluten in Male Albino Mice
Bioscience Journal, 2023 Gluten is a protein commonly found in daily diets in the form of wheat, barley, rye, and other grains. It serves as the structural component in flour, providing the binding qualities that maintain the shape and texture of food items.

Thirty Years of Cometary Spectroscopy from McDonald Observatory [PDF]
, 2011 We report on the results of a spectroscopic survey of 130 comets that was conducted at McDonald observatory from 1980 through 2008. Some of the comets were observed on only one night, while others were observed repeatedly. For 20 of these comets, no molecules were detected.

The Composition of Dust in Jupiter-Family Comets as Inferred from Infrared Spectroscopy [PDF]
, 2008 We review the composition of Jupiter-family comet dust as inferred from infrared spectroscopy. We find that Jupiter-family comets have 10 micron silicate emission features with fluxes roughly 20-25% over the dust continuum (emission strength 1.20-1.25), similar to the weakest silicate features in Oort Cloud comets.

Dynamics and Origin of Comets: New Problems Appeared after the Rosetta Space Mission [PDF]
Solar System Research, 2018, Volume 52, 382-391, 2019 The data obtained in the recent Rosetta space mission to comet 67P/Churyumov-Gerasimenko have had a profound impact on the understanding of the nature of comets. In addition to revising the notions on the physical properties and structure of comets, this addresses dynamical aspects of the formation of the observed cometary populations (short- and long ...

High-resolution optical spectroscopic observations of comet 21P/Giacobini-Zinner in Its 2018 apparition [PDF]
Astron. J., 159, 203 (2020), 2020 Comet 21P/Giacobini-Zinner is a peculiar comet from the viewpoints of the chemical and physical properties of its dust grains. We conduct optical high-resolution spectroscopic observations of the comet. The intensity ratios of forbidden oxygen lines (at 557.7, 630.0, and 636.4 nm) and ortho-to-para abundance ratios (OPRs) of water cations (H$_2$O ...

On the Detection and Distribution of Nongravitational Accelerations in the Motions of Long-Period Comets [PDF]
arXiv, 2021 Even though the orbital motions of most long-period comets are found to comply with the gravitational law, a rapidly increasing minority of these objects is found to display detectable outgassing-driven deviations. The systematic research of nongravitational effects in the motions of long-period comets began with Hamid & Whipple's work aimed to support

Comet Science With Ground Based and Space Based Surveys in the New Millennium [PDF]
arXiv, 2022 We summarize the comet science provided by surveys. This includes surveys where the detections of comets are an advantageous benefit but were not part of the survey\'s original intent, as well as some pointed surveys where comet science was the goal. Many of the surveys are made using astrophysical and heliophysics assets.

The Great Comet and Schmidt's Comet [PDF]
Nature, 1882 THERE can be no doubt of the elongation of the nucleus of the Great Comet in the direction of the axis of the tail, in which direction it is three times as long as in a direction at right angles thereto.

Cold traps of hypervolatiles in the protosolar nebula at the origin of comet C/2016 R2 (PanSTARRS)'s peculiar composition [PDF]
arXiv, 2021 Recent observations of the long period comet C/2016 R2 (PanSTARRS) indicate an unusually high N2/CO abundance ratio, typically larger than 0.05, and at least 2-3 times higher than the one measured in 67P/Churyumov-Gerasimenko. Another striking compositional feature of this comet is its heavy depletion in H2O, compared to other comets.
