In vivo molecular engineering of the urethra for treatment of stress incontinence using novel biomimetic proteoglycans.

J Biomed Mater Res B Appl Biomater 2019 Feb 19. Epub 2019 Feb 19.

Materials Science and Engineering, Drexel University, Philadelphia, Pennsylvania 19104.

Stress urinary incontinence (SUI), a serious condition which affects ~56% of postmenopausal women, is the involuntary leakage of urine through urethra during physical activity that causes an increase in abdominal pressure. SUI is associated with a decrease in compliance and volume of urethral tissue, likely due to a reduced proteoglycan: collagen ratio in the extracellular matrix and collagen disorganization. Here, we investigated the use of biomimetic proteoglycans (BPGs) to molecularly engineer urethral tissue of New Zealand White rabbits to examine biocompatibility in vivo. Read More

Current concepts and recent advances in understanding and managing lumbar spine stenosis.

F1000Res 2019 31;8. Epub 2019 Jan 31.

Neurosurgery, University of Texas Southwestern Medical Center at Dallas, Dallas, TX, USA.

Lumbar spinal stenosis is a degenerative process that is extremely frequent in today's aging population. It can result in impingement on the nerves of the cauda equina or on the thecal sac itself, and lead to debilitating symptoms such as severe leg pain, or restriction in the perimeter of ambulation, both resulting in dependency in daily activities. The impact of the disease is global and includes financial repercussions because of its involvement in the active work force group. Read More

The preventive and therapeutic effects of molecular hydrogen in ocular diseases and injuries where oxidative stress is involved.

Free Radic Res 2019 Feb 18:1-241. Epub 2019 Feb 18.

a Institute of Experimental Medicine , Chinese Academy of Sciences , Prague , Czech Republic.

Oxidative stress initiates, accompanies and contributes to the development of several human diseases and injuries, including ocular diseases. Reactive oxygen species (ROS) can generate oxidative stress via excessive ROS production and/or decreased physiologically occurring antioxidants. To replace these weakened antioxidants, substances with effective antioxidant properties are needed in order to suppress oxidative stress and enable healing. Read More

Potential role of Anitschkow cells in cardiovascular disease in human and veterinary medicine: A review of the literature.

Anat Histol Embryol 2019 Feb 17. Epub 2019 Feb 17.

Department of Veterinary Sciences, University of Turin, Grugliasco, Turin, Italy.

Anitschkow cells (AC) are a peculiar type of stromal cells observed in myocardium, cardiac valves and coronary vessels wall whose origin, characterization and role remain controversial. In human heart, they represent a histological hallmark of Aschoff nodules in rheumatic fever, but they have also been observed in other myocardial pathologies. Firstly, they have been considered a myocyte-derived cells, but light microscopy, immunohistochemical and ultrastructural studies pointed out that a macrophagic/histiocytic origin cannot be excluded.

Talin promotes integrin activation accompanied by generation of tension in talin and an increase in osmotic pressure in neurite outgrowth.

FASEB J 2019 Feb 15:fj201801949RR. Epub 2019 Feb 15.

State Key Laboratory Cultivation Base for Traditional Chinese Medicine (TCM) Quality and Efficacy, School of Medicine and Life Science, Nanjing University of Chinese Medicine, Nanjing, China.

Neuronal polarization depends on the interaction of intracellular chemical and mechanical activities in which the cytoplasmic protein, talin, plays a pivotal role during neurite growth. To better understand the mechanism underlying talin function in neuronal polarization, we overexpressed several truncated forms of talin and found that the presence of the rod domain within the overexpressed talin is required for its positive effect on neurite elongation because the neurite number only increased when the talin head region was overexpressed. The tension in the talin rod was recognized using a Förster resonance energy transfer-based tension probe. Read More

Corpora amylacea in human hippocampal brain tissue are intracellular bodies that exhibit a homogeneous distribution of neo-epitopes.

Sci Rep 2019 Feb 14;9(1):2063. Epub 2019 Feb 14.

Secció de Fisiologia, Departament de Bioquímica i Fisiologia, Universitat de Barcelona, Barcelona, Spain.

Corpora amylacea are spherical bodies of unknown origin and function, which accumulate in the human brain during the aging process and neurodegenerative disorders. In recent work, we reported that they contain some neo-epitopes that are recognized by natural IgMs, revealing a possible link between them and the natural immune system. Here, we performed an ultrastructural study complemented with confocal microscopy in order to shed light on the formation of corpora amylacea and to precisely localize the neo-epitopes. Read More

The development of white matter structural changes during the process of deterioration of the visual field.

Sci Rep 2019 Feb 14;9(1):2085. Epub 2019 Feb 14.

Department of Medical Neurobiology, The Institute for Medical Research Israel-Canada, Faculty of Medicine, The Hebrew University of Jerusalem, 91220, Jerusalem, Israel.

Emerging evidence suggests that white matter plasticity in the adult brain is preserved after sensory and behavioral modifications. However, little is known about the progression of structural changes during the process of decline in visual input. Here we studied two groups of patients suffering from advanced retinitis pigmentosa with specific deterioration of the visual field: patients who had lost their peripheral visual field, retaining only central ("tunnel") vision, and blind patients with complete visual field loss.
