An ultralow dose paclitaxel coated drug balloon with an outer protective sheath for peripheral arterial disease treatment.

J Mater Chem B 2021 03;9(10):2428-2435

National Engineering Research Center for Biomaterials, Sichuan University, Chengdu, 610064, P. R. China.

Use of a drug-eluting coated balloon (DCB) represents a promising therapeutic method for peripheral arterial disease (PAD) due to its advantages such as no implant permanently retained in the patient and no inflammatory reaction and endothelialization barrier caused by a permanent stent. However, there is still a huge challenge of controlling the release of drugs from the DCB into vessel tissue. The uncontrolled release of drugs and high drug loading amounts could potentially lead to distal embolization and mortality events. Read More

Assessment of lying down behaviour in temporarily crated lactating sows.

Animal 2021 Feb 25;15(2):100130. Epub 2020 Dec 25.

Faculty of Agrobiology, Food and Natural Resources, Czech University of Life Sciences Prague, Kamýcká 129, 160 21 Praha-Suchdol, Czech Republic.

Temporary crating may be a more acceptable housing system for lactating sows than permanent crating from an animal welfare point of view. It remains unclear whether opening the crate leads to changes in sow lying down behaviour and piglet activity that may pose an increased risk of injury to piglets. This study aimed to assess whether the lying down behaviour of lactating sows housed in temporary crating changed shortly after removal of confinement, whether it was influenced by piglets' behaviour and age and whether sows preferentially used some support during lying down after crate opening.

Chronic Hyperglycemia Drives Functional Impairment of Lymphocytes in Diabetic Transgenic Pigs.

Front Immunol 2020 22;11:607473. Epub 2021 Jan 22.

Chair of Physiology, Department of Veterinary Sciences, LMU Munich, Munich, Germany.

People with diabetes mellitus have an increased risk for infections, however, there is still a critical gap in precise knowledge about altered immune mechanisms in this disease. Since diabetic transgenic pigs exhibit elevated blood glucose and a stable diabetic phenotype soon after birth, they provide a favorable model to explore functional alterations of immune cells in an early stage of diabetes mellitus . Hence, we investigated peripheral blood mononuclear cells (PBMC) of these diabetic pigs compared to non-diabetic wild-type littermates. Read More

Semi-Automated Cell and Tissue Analyses Reveal Regionally Specific Morphological Alterations of Immune and Neural Cells in a Porcine Middle Cerebral Artery Occlusion Model of Stroke.

Front Cell Neurosci 2020 22;14:600441. Epub 2021 Jan 22.

Regenerative Bioscience Center, University of Georgia, Athens, GA, United States.

Histopathological analysis of cellular changes in the stroked brain provides critical information pertaining to inflammation, cell death, glial scarring, and other dynamic injury and recovery responses. However, commonly used manual approaches are hindered by limitations in speed, accuracy, bias, and the breadth of morphological information that can be obtained. Here, a semi-automated high-content imaging (HCI) and CellProfiler histological analysis method was developed and used in a Yucatan miniature pig permanent middle cerebral artery occlusion (pMCAO) model of ischemic stroke to overcome these limitations.
