Aims: Oxidative stress may contribute to the development of chronic pancreatitis (CP). The enzymes manganese superoxide dismutase 2 (MnSOD, SOD2) and catalase (CAT) counteract free radical activity within the mitochondria and the cytosol. Moreover, CAT activity contributes to the transformation of ethanol to acetaldehyde, a toxic intermediate product of ethanol metabolism, which has been associated with pancreatic damage. Common functional polymorphisms have been described in the MnSOD gene [rs4880, NM_000636...

Understanding the pathogenesis of complex diseases can benefit from multi-species comparative studies. Yet these studies rarely include natural populations of non-model species. Here, we focused on the cause of a heart muscle disease, cardiomyopathy (CM), affecting multiple mammalian species including humans, cats, dogs, and certain species of whales. Mutations in genes coding for sarcomeric proteins have been identified as a leading cause for CM in humans, and some were also revealed to be responsible for CM in cats...

Brain atlases play an important role in effectively communicating results from neuroimaging studies in a standardized coordinate system. Furthermore, brain atlases extend analysis of functional magnetic resonance imaging (MRI) data by delineating regions of interest over which to evaluate the extent of functional activation as well as measures of inter-regional connectivity. Here we introduce a three-dimensional atlas of the cat cerebral cortex based on established cytoarchitectonic and electrophysiological findings...

Adrenomedullin (AM) is a peptide involved in blood pressure regulation. AM activates three different receptors, the AM type 1 (AM1), type 2 (AM2), and calcitonin gene-related peptide 1 (CGRP1) receptors. AM triggers several signaling pathways such as adenylyl cyclase (AC), guanylyl cyclase (GC), and extracellular signal-regulated kinases (ERK) and modulates reactive oxygen species (ROS) metabolism. Cerebellar AM, AM-binding sites, and its receptor components are altered during hypertension, although it is unknown if these alterations are associated with changes in AM signaling...

Murine typhus is a rickettsiosis caused by Rickettsia typhi, whose transmission is carried out by rat fleas in urban settlements as classically known, but it also has been related to cat fleas in a sub-urban alternative cycle that has been suggested by recent reports. These studies remarks that in addition to rats, other animals like cats, opossums and dogs could be implied in the transmission of Rickettsia typhi as infected fleas obtained from serologically positive animals have been detected in samples from endemic areas...

DNA methylation is an epigenetic mechanism controlling gene expression without affecting DNA sequences, and aberrant DNA methylation patterns are features of a number of diseases. Notably, epigenetic errors in cancer cells have been intensively studied over the last two decades in humans; however, little is known concerning dogs and cats. To analyze DNA methylation and gene expression changes in feline lymphoma cells, we added the DNA methylation inhibitor 5-aza-2'-deoxycytidine (5-aza) to three cell lines (3281 and FT-1 cells derived from T-cell lymphoma and MS4 cells derived from B-cell lymphoma)...

We described the time trend of acute myocardial infarction (AMI) from 1999 to 2013 in Tianjin incidence rate with Cochran-Armitage trend (CAT) test and linear regression analysis, and the results were compared. Based on actual population, CAT test had much stronger statistical power than linear regression analysis for both overall incidence trend and age specific incidence trend (Cochran-Armitage trend P value<linear regression P value). The statistical power of CAT test decreased, while the result of linear regression analysis remained the same when population size was reduced by 100 times and AMI incidence rate remained unchanged...

Spatial transposition tasks assess individuals' ability to represent nonvisible spatial object displacements. Several nonhuman mammal species have been tested on this task including primates, cats, and dogs, but to date, great apes seem the only taxon that has repeatedly and consistently solved spatial transposition tasks. The authors investigated the ability of captive sloth and sun bears to solve spatial transposition tasks. Both species belong to the same taxonomic group as cats and dogs, but unlike them and similar to apes, they have an omnivorous diet that requires them to keep track of fruit sources in space and time...

Mulberry fruit polysaccharide (MFP), one of the major active ingredients isolated from the mulberry fruit, possesses numerous bioactivities. In vitro hypoglycemic experiments showed that MFP had significant insulin-sensitizing activity through increasing insulin secretion and promoting pancreatic β cell proliferation. In vivo, the oral administration of MFP could significantly decrease blood glucose levels and increase body weight loss in streptozotocin (STZ)-induced diabetic mice. MFP also significantly decreased the level of malondialdehyde (MDA) and increased the activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) in the liver in STZ-induced diabetic mice...
