The physical and chemical structure of Sagittarius B2, I. Three-dimensional thermal dust and free-free continuum modeling on 100 au to 45 pc scales [PDF]

open access: yesA&A 588, A143 (2016), 2016
We model the dust and free-free continuum emission in the high-mass star-forming region Sagittarius B2 in order to reconstruct the three-dimensional density and dust temperature distribution, as a crucial input to follow-up studies of the gas velocity field and molecular abundances. We employ the three-dimensional radiative transfer program RADMC-3D to

Breaking barriers: Smart vaccine platforms for cancer immunomodulation

open access: yesCancer Communications, EarlyView.
Abstract Despite significant advancements in cancer treatment, current therapies often fail to completely eradicate malignant cells. This shortfall underscores the urgent need to explore alternative approaches such as cancer vaccines. Leveraging the immune system's natural ability to target and kill cancer cells holds great therapeutic potential ...

The effect of acidifier supplementation on egg production performance and intestinal histology of Japanese quail (Coturnix japonica)

open access: yesVeterinary Medicine and Science, Volume 9, Issue 1, Page 263-271, January 2023., 2023
This study aimed to investigate the effect of dietary supplementation of a commercial acidifier on egg production and histology of small intestine in laying Japanese quail. Our results indicate that supplementation of 1 and 2.6 g acidifier per kg of diet was associated with beneficial effects on egg production and quality, GIT pH and histology of small

Submillimeter continuum observations of Sagittarius B2 at subarcsecond spatial resolution [PDF]

open access: yes, 2011
We report the first high spatial resolution submillimeter continuum observations of the Sagittarius B2 cloud complex using the Submillimeter Array (SMA). With the subarcsecond resolution provided by the SMA, the two massive star-forming clumps Sgr B2(N) and Sgr B2(M) are resolved into multiple compact sources.

Purine Chemistry in the Early RNA World at the Origins of Life: From RNA and Nucleobases Lesions to Current Key Metabolic Routes

open access: yesChemBioChem, EarlyView.
In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

A Novel LC-MS/MS Assay for Vitamin B1, B2 and B6 Determination in Driedblood Spots and Its Application in Children

open access: yesCurrent Developments in Nutrition, 2020
Several HPLC assays can be used to determine vitamin B1 (thiamin), B2 (riboflavin) and B6 (PLP) in biological matrix. However, no existing LC-MS/MS methods have been developed for quantifying thiamin, riboflavin and PLP in dried blood spots (DBSs),

Fluorescence Spectroscopy of Flour Fractions and Dough: Analysis of Spectral Differences and Potential to Improve Wheat Quality Prediction

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Spectroscopy of wheat kernels and flour has been used as a rapid tool to assess wheat quality, but predictions still lack in accuracy for most quality parameters except for protein content. To enable an improved prediction of further quality characteristics, new approaches are needed.

Prediction of strain engineerings that amplify recombinant protein secretion through the machine learning approach MaLPHAS

open access: yesEngineering Biology, Volume 6, Issue 4, Page 82-90, December 2022., 2022
Abstract This article presents a discussion of the process of precision fermentation (PF), describing the history of the space, the expected 70% growth over the next 5 years, various applications of precision fermented products, and the markets available to be disrupted by the technology. A range of prokaryotic and eukaryotic host organisms used for PF
