Abstract Background Studies performed in multiple preclinical models support the contribution of Ca2+-dependent cysteine proteases calpains to ventricular remodelling and heart failure (HF). However, pharmacological calpain inhibition has not yet been tested patients with HF mainly due limitations available inhibitors. Purpose To determine effect NPO-2270 (NPO), a new ketoamide derivative inhib...

background: although cervical cancer mortality has reduced during last years, but it is still leading cause of mortality among women. many efforts have performed to develop new drugs and strategy to cure cervical cancer. mesenchymal stem cells (mscs) have many advantages that make them a suitable choice as a cell therapeutic agent in cancer treatment. there are different transfection methods fo...

Mouse models of chronic obstructive pulmonary disease (COPD) focus on airway inflammation and lung histology, but their use has been hampered by the lack of pulmonary function data in their assessment. Systemic effects such as muscle dysfunction are also poorly modeled in emphysematous mice. We aimed to develop a cigarette-smoke-induced emphysema mouse model in which serial lung function and mu...

background: the study of specific genes expressed in the testis is important to understanding testis development and function. spermatogenesis is an attractive model for the study of gene expression during germ cell differentiation. spermatogenesis associated-19 (spata-19) is a recently-identified important spermatogenesis-related gene specifically expressed in testis. its protein product is in...

PURPOSE We hypothesized that CIH may affect the upper airway immune system and aimed to verify whether CIH can induce airway inflammation in a murine obstructive sleep apnea (OSA) model. METHODS C57BL6 male mice were exposed to intermittent hypoxia (CIH group; 5 ~ 21% FiO2, 120 sec cycles, 12 h/d, n = 6) or room air (Sham group, n = 6) for up to 4 weeks in identical chambers. Nasal and lung t...

Corneal neovascularization leads to blurred vision, thus in vivo visualization is essential for pathological studies in animal models. Photoacoustic (PA) imaging can delineate microvasculature and hemodynamics noninvasively, which is suitable for investigating corneal neovascularization. In this study, we demonstrate in vivo imaging of corneal neovascularization in the mouse eye by optical-reso...

Effective representation of the diffusion signal’s dependence on diffusion time is a sought-after, yet still unsolved, challenge in diffusion MRI (dMRI). We propose a functional basis approach that is specifically designed to represent the dMRI signal in this four-dimensional space – varying over gradient strength, direction and diffusion time. In particular, we provide regularization tools imp...

The molecular mechanisms that regulate self-renewal and differentiation of very primitive hematopoietic stem and progenitor cells in vivo are still poorly understood. Despite the clinical relevance, even less is known about the mechanisms that regulate these cells in old animals. In a forward genetic approach, using quantitative trait linkage analysis in the mouse BXD recombinant inbred set, th...

Vasectomy in laboratory animals is a crucial step in the production of surrogate female mice. The surrogate mothers play a key role in successful embryo transfer, most important steps for the production of transgenic animal models, investigation of the preimplantation embryo development, and revitalization of cryopreserved strains. Abdominal and scrotal surgeries are common surgical proce...
