Intermedin inhibits norepinephrine-induced contraction of rat seminal vesicle

open access: yesAsian Pacific Journal of Reproduction, 2014
Objective: To study the effect of inter medin(IMD) on smooth muscle of rat seminal vesicles including the specific receptors and the signal pathways involved. Methods: The contraction of the seminal vesicle in response to norepinephrine (NE) and ADM2/IMD

Metabolism within the tumor microenvironment and its implication on cancer progression: an ongoing therapeutic target [PDF]

open access: yes, 2018
Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years.

Rapid severe hypertension and organ damage in two‐kidney two‐clip rats produced by different sizes of clips

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 8, Page 1456-1467, August 2025.
Blood pressure increases immediately when the 2K2C rats (made with 0.3, 0.25, and 0.2 mm U‐shaped clips) regain consciousness from anesthesia. 100% of the rats develop hypertension on the day of 2K2C surgery. Blood pressure continues to rise, resulting in severe hypertension and organ damage to the brain, heart, aorta, and kidneys at 1, 2, 4, and 6 ...

Effects of nitric oxide inhibitors in mice with bladder outlet obstruction

open access: yesInternational Brazilian Journal of Urology
Purpose To investigate the lower urinary tract changes in mice treated with L-NAME, a non-selective competitive inhibitor of nitric oxide synthase (NOS), or aminoguanidine, a competitive inhibitor of inducible nitric oxide synthase (iNOS), after 5 weeks

Alterations of myocardial ketone metabolism in heart failure with preserved ejection fraction (HFpEF)

open access: yesESC Heart Failure, Volume 12, Issue 4, Page 3179-3182, August 2025.
Abstract Introduction Cardiac energy metabolism is disrupted in heart failure with preserved ejection fraction (HFpEF), as characterized by a switch from glucose oxidation towards fatty acid oxidation. However, although oxidation of ketones is an important source of ATP it remains unclear how the heart oxidizes ketones in HFpEF.

Aging‐Associated Liver Sinusoidal Endothelial Cells Dysfunction Aggravates the Progression of Metabolic Dysfunction‐Associated Steatotic Liver Disease

open access: yesAging Cell, Volume 24, Issue 5, May 2025.
Aged rats and human are more susceptible to MASLD‐related liver injury, steatosis, and fibrosis, accompanied by worsening of endothelial dysfunction. The SIRT1/p‐eNOS/NO pathway is involved in aggravated MASLD caused by aging‐related LSECs dysfunction.

Maternal tadalafil therapy for fetal growth restriction prevents non-alcoholic fatty liver disease and adipocyte hypertrophy in the offspring

open access: yesScientific Reports, 2021
We aimed to investigate the effects of maternal tadalafil therapy on fetal programming of metabolic function in a mouse model of fetal growth restriction (FGR). Pregnant C57BL6 mice were divided into the control, L-NG-nitroarginine methyl ester (L-NAME),

Evaluation of the potential role of glutamatergic, cholinergic, and nitrergic systems in the dopamine release induced by the pesticide glyphosate in rat striatum

open access: yesJournal of Applied Toxicology, Volume 44, Issue 10, Page 1489-1503, October 2024.
Abstract Glyphosate (GLY) is a pesticide that severely alters nigrostriatal dopaminergic neurotransmission, inducing great increases in dopamine release from rat dorsal striatum. This GLY‐induced striatal dopamine overflow occurs through mechanisms not yet fully understood, hence the interest in evaluating the role of other neurotransmitter systems in ...

Acidosis potentiates endothelium-dependent vasorelaxation and gap junction communication in the superior mesenteric artery. [PDF]

open access: yes, 2018
Extracellular pH is an important physiological determinant of vascular tone that is normally maintained within 7.35-7.45. Any change outside this range leads to severe pathological repercussions.
