Spectroscopic properties of Vitamin C: A theoretical work
Cumhuriyet Science Journal, 2020 Vitamin C is an important human micronutrient. It has many vital biological functions in human health. In this research paper, the molecule of vitamin C was optimized and energy band gaps were determined using DFT and HF methods. In computational quantum

HF pump-induced electron heating and artificial airglow at high latitudes: Aspect angle dependence [PDF]
, 2002 Large electron temperature increases (~3000 K) in the ionospheric F-region, produced by powerful HF wave injection, were measured using the EISCAT incoherent scatter radar near Tromsø, Norway, on 7 October 1999.

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3
Molecular Oncology, EarlyView.PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Studies of dispersion energy in hydrogen-bonded systems. H2O–HOH, H2O–HF, H3N–HF, HF–HF
The Journal of Chemical Physics, 1984 Dispersion energy is calculated in the systems H2O–HOH, H2O–HF, H3N–HF, and HF–HF as a function of the intermolecular separation using a variety of methods. M≂ller–Plesset perturbation theory to second and third orders is applied in conjunction with polarized basis sets of 6-311G** type and with an extended basis set including a second set of ...
