Dietary nitrate and nitrite protect against doxorubicin‐induced cardiac fibrosis and oxidative protein damage in tumor‐bearing mice

open access: yesFEBS Open Bio, EarlyView.
Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

Blistering and deuterium retention in Nb-doped W exposed to low-energy deuterium plasma

open access: yesNuclear Materials and Energy, 2020
Tungsten and tungsten-niobium alloy with niobium concentration of 5 wt% were exposed to deuterium plasma at ~470 – 506 K, with flux of ~1.8 × 1021 D/m2/s, an ion energy of 100 eV and fluence of 1.3 × 1025 D/m2 – 5.2 × 1025 D/m2.

On the robustness of cointegration tests when series are fractionally integrated [PDF]

open access: yes, 1996
This paper shows, analytically and numerically, the effects of a misspecification in the degree of integration on testing for cointegration. Johansen LR tests tend to find too much spurious cointegration while the Engle-Granger test shows a more robust ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

BAO signatures in the 2-point angular correlations and the Hubble tension

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
An observational tension on estimates of the Hubble parameter, $$H_0$$ H 0 , using early and late Universe information, is being of intense discussion in the literature.

Anticancer sensitivities and biological characteristics of HCT116 cells resistant to the selective poly(ADP‐ribose) glycohydrolase inhibitor

open access: yesFEBS Open Bio, EarlyView.
We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a

Hyperbaric Normoxia Improved Glucose Metabolism and Decreased Inflammation in Obese Diabetic Rat

open access: yesJournal of Diabetes Research, 2019
Hyperbaric treatment improves hyperglycemia and hyperinsulinemia in type 2 diabetes associated with obesity. However, its mode of action is unknown. The purpose of the present study was to investigate the influences of regular hyperbaric treatment with ...

Prevalence of vitamin D deficiency among Northern Muslim women with chronic musculoskeletal pain residing in Port Harcourt, Rivers State, Nigeria: a cross-sectional study [PDF]

open access: yesExploration of Musculoskeletal Diseases
Aim: Vitamin D deficiency is increasingly recognised as a global health concern and is associated with musculoskeletal pain. Women adhering to cultural clothing practices may be at increased risk due to limited sun exposure. This study aimed to determine
