Synthesis of some novel annulated pyrido[2,3-d]pyrimidines via stereoselective intramolecular hetero Diels–Alder reactions of 1-oxa-1,3-butadienes

Beilstein Journal of Organic Chemistry, 2010
Some novel annulated pyrido[2,3-d]pyrimidines 6 and 7 were synthesized stereoselectively by intramolecular hetero Diels–Alder reactions involving 1-oxa-1,3-butadienes.

A unique uracil-DNA binding protein of the uracil DNA glycosylase superfamily

, 2015
Uracil DNA glycosylases (UDGs) are an important group of DNA repair enzymes, which pioneer the base excision repair pathway by recognizing and excising uracil from DNA.

Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

Sustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

Genetic Tools in the Nakaseomyces clade for Evolutionary Comparisons of Signal Transduction Pathways

Yeast, EarlyView.
ABSTRACT The genus Nakaseomyces provides four species that are closely related but have different characteristics. For example, N. glabratus (formerly known as Candida glabrata) is a common human pathogen, whereas N. bracarensis and N. nivariensis have been isolated in clinical settings but are not common human pathogens. N.

Comparative Analysis of Stress Adaptation in the Yeast Microbiome of Cactus

Yeast, EarlyView.
Yeasts and related fungi isolated from cacti or nearby non‐cactus plants were characterized phenotypically and genomically, revealing differences that hint at modes of adaptation to the cactus host. ABSTRACT Together with other fungi, yeasts make up a significant component of the plant microbiome. As the planet warms, cacti expand their range.

Tautomerism of uracil probed via IR spectroscopy of singly hydrated uracil.

, 2008
International audienceTautomerism of the nucleobase uracil is characterized in the gas phase through IR photodissociation spectroscopy of singly hydrated protonated uracil created with tandem mass spectrometric methods in a commercially available Fourier

Evaluation of bone preparation approaches using length‐based analysis and targeted sequencing for forensic human identification of historic skeletal remains

Journal of Forensic Sciences, EarlyView.
Abstract Advances in DNA technology have significantly enhanced the forensic community's ability to develop genetic profiles from unidentified human skeletal remains. However, sampling requires mechanical grinding of hard tissues before DNA isolation. This processing can compromise genetic profiles, particularly in aged bones.

MAP17 Enhances Chemoresistance and Tumorigenicity of Glioblastoma‐Initiating Cells via the Canonical NF‐кB Pathway

Cancer Science, EarlyView.
MAP 17 is identified as highly expressed in TMZ‐resistant glioblastoma‐initiating cells (GICs). MAP17 enhances GIC proliferation, TMZ resistance, and tumorigenicity through NF‐κB/RELA‐dependent BCL2 upregulation. ABSTRACT Glioblastoma (GBM) is the most common malignant brain tumor in adults.
