The Plasminogen Activation System Promotes Neurorepair in the Ischemic Brain.

Authors:
Manuel Yepes

Curr Drug Targets 2018 Dec 11. Epub 2018 Dec 11.

Division of Neuropharmacology and Neurologic Diseases, Yerkes National Primate Research Center; Atlanta, GA. United States.

The plasminogen activation (PA) system was originally thought to exclusively promote the degradation of fibrin by catalyzing the conversion of plasminogen into plasmin via two serine proteinases: tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA). However, experimental evidence accumulated over the last 30 years indicates that tPA and uPA are also found in the central nervous system (CNS), where they have a plethora of functions that not always require plasmin generation or fibrin degradation. For example, plasminogen-dependent and -independent effects of tPA and uPA play a central role in the pathophysiological events that underlie one of the leading causes of mortality and disability in the world: cerebral ischemia.

Artificial Neural Network to Predict Varicocele Impact on Male Fertility through Testicular Endocannabinoid Gene Expression Profiles.

Biomed Res Int 2018 13;2018:3591086. Epub 2018 Nov 13.

Faculty of Biosciences and Technology for Food, Agriculture and Environment, University of Teramo, 64100 Teramo, Italy.

The relationship between varicocele and fertility has always been a matter of debate because of the absence of predictive clinical indicators or molecular markers able to define the severity of this disease. Even though accumulated evidence demonstrated that the endocannabinoid system (ECS) plays a central role in male reproductive biology, particularly in the testicular compartment, to date no data point to a role for ECS in the etiopathogenesis of varicocele. Therefore, the present research has been designed to investigate the relationship between testicular ECS gene expression and fertility, using a validated animal model of experimental varicocele (VAR), taking advantage of traditional statistical approaches and artificial neural network (ANN).

Origin, Differentiation, and Function of Intestinal Macrophages.

Front Immunol 2018 27;9:2733. Epub 2018 Nov 27.

Centre for Inflammation Research, University of Edinburgh, Edinburgh, United Kingdom.

Macrophages are increasingly recognized as essential players in the maintenance of intestinal homeostasis and as key sentinels of the intestinal immune system. However, somewhat paradoxically, they are also implicated in chronic pathologies of the gastrointestinal tract, such as inflammatory bowel disease (IBD) and are therefore considered potential targets for novel therapies. In this review, we will discuss recent advances in our understanding of intestinal macrophage heterogeneity, their ontogeny and the potential factors that regulate their origin. Read More

Institute of Medical Microbiology, University of Zürich, Zürich, Switzerland

is the causative agent of a pneumonia termed Legionnaires' disease. The facultative intracellular bacterium employs the Icm/Dot type IV secretion system (T4SS) and a plethora of translocated "effector" proteins to interfere with host vesicle trafficking pathways and establish a replicative niche, the -containing vacuole (LCV). Internalization of the pathogen and the events immediately ensuing are accompanied by host cell-mediated phosphoinositide (PI) lipid changes and the Icm/Dot-controlled conversion of the LCV from a PtdIns(3)-positive vacuole into a PtdIns(4)-positive replication-permissive compartment, which tightly associates with the endoplasmic reticulum.

Engrafted parenchymal brain macrophages differ from microglia in transcriptome, chromatin landscape and response to challenge.

Nat Commun 2018 12 6;9(1):5206. Epub 2018 Dec 6.

Department of Immunology, Weizmann Institute of Science, Rehovot, 76100, Israel.

Microglia are yolk sac-derived macrophages residing in the parenchyma of brain and spinal cord, where they interact with neurons and other glial. After different conditioning paradigms and bone marrow (BM) or hematopoietic stem cell (HSC) transplantation, graft-derived cells seed the brain and persistently contribute to the parenchymal brain macrophage compartment. Here we establish that graft-derived macrophages acquire, over time, microglia characteristics, including ramified morphology, longevity, radio-resistance and clonal expansion. Read More

Metabolic Host Response to Intracellular Infections.

Exp Suppl 2018 ;109:319-350

Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, Braga, Portugal.

The interaction between intracellular bacterial pathogens with the host immune response can result in multiple outcomes that range from asymptomatic clearance to the establishment of infection. At its core, these interactions result in multiple metabolic adaptations of both the pathogen and its host cell. There is growing evidence that the host metabolic response plays a key role in the development of immune responses against the invading pathogen. Read More

Pathways of host cell exit by intracellular pathogens.

Microb Cell 2018 Oct 18;5(12):525-544. Epub 2018 Oct 18.

Division of Cellular and Applied Infection Biology, Institute of Biology II, RWTH Aachen University, Germany.

Host cell exit is a critical step in the life-cycle of intracellular pathogens, intimately linked to barrier penetration, tissue dissemination, inflammation, and pathogen transmission. Like cell invasion and intracellular survival, host cell exit represents a well-regulated program that has evolved during host-pathogen co-evolution and that relies on the dynamic and intricate interplay between multiple host and microbial factors. Three distinct pathways of host cell exit have been identified that are employed by three different taxa of intracellular pathogens, bacteria, fungi and protozoa, namely (i) the initiation of programmed cell death, (ii) the active breaching of host cellderived membranes, and (iii) the induced membrane-dependent exit without host cell lysis.

Using a three-compartment model improves the estimation of iohexol clearance to assess glomerular filtration rate.

Sci Rep 2018 Dec 7;8(1):17723. Epub 2018 Dec 7.

Institute of Public Health, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Berlin, Germany.

Plasma clearance of iohexol is a key tool to precisely determine glomerular filtration rate (GFR) in clinical research and clinical practice. Despite evidence that iohexol pharmacokinetics are described best by three-compartment models, two-compartment approaches (Schwartz approach) are customary, which might result in avoidable bias and imprecision. We aimed to provide a population pharmacokinetic (popPK) model of iohexol by re-evaluating data from the Berlin Initiative Study (BIS) to compare respective clearance estimates to the Schwartz approach and to assess the impact of revised clearance estimates on the BIS equations.

Gadolinium-based contrast agents: why nephrologists need to be concerned.

Curr Opin Nephrol Hypertens 2018 Dec 3. Epub 2018 Dec 3.

Kidney Institute of New Mexico.

Purpose Of Review: The hegemony of gadolinium-based contrast agent-induced adverse events stretches beyond those who have renal impairment. 'Nephrogenic' systemic fibrosis is a misnomer: gadolinium-based contrast agents are the known trigger for the disease; kidney impairment is a risk factor. Impaired (true) glomerular filtration may be one catalyst for gadolinium-based contrast agent-induced adverse events, but it is increasingly evident that the same cluster of symptoms occurs in patients with normal renal function.

Beta-secretase 1 (BACE1) is a key enzyme in the generation of beta-amyloid, which is accumulated in the brain of Alzheimer's disease (AD) patients. PF-06684511 was identified as a candidate PET ligand for imaging BACE1 in the brain, and showed high specific binding in an initial assessment in a non-human primate (NHP) PET study utilizing F-PF-06684511. In this effort, we aimed to quantitatively evaluate the regional brain distribution of F-PF-06684511 in NHPs under baseline and blocking conditions as well as assess the target occupancy of BACE1 inhibitors.

Background: The aim of the present study was to evaluate the relationship between tibial slope angle and ligament strain during in vitro landing simulations that induce ACL failure through the application of variable external loading at the knee. The hypothesis tested was that steeper posterior tibial slope angle would be associated with higher ACL strain during a simulated landing task across all external loading conditions.

Methods: Kinetics previously derived from an in vivo cohort performing drop landings were reproduced on 45 cadaveric knees via the mechanical impact simulator. Read More

Cerrado ecoregions: A spatial framework to assess and prioritize Brazilian savanna environmental diversity for conservation.

J Environ Manage 2018 Dec 5;232:818-828. Epub 2018 Dec 5.

Embrapa Informática Agropecuária, CEP: 13083-886, Campinas, SP Brazil. Electronic address:

The Brazilian Cerrado is the second largest biome in Latin America, extending over more than 200 million ha and hosts some of the most intensive agricultural activities for grain and beef production in the world. Because of the biodiversity richness and high levels of endemism, Cerrado is considered one of world's hotspot for biodiversity conservation. The objectives of this study are three-fold: to present a comprehensive division of Cerrado into different ecoregions that reflect the environmental heterogeneity within the biome; to analyze the ecoregions in terms of biophysical characteristics, protected areas, environmental liability in riparian permanent protection areas along watercourses, and priorities for biodiversity conservation; and to rank the ecoregions in terms of endangerment for biodiversity conservation and restoration.

Electronic address:

After uptake by epithelial cells or engulfment by macrophages, Salmonella resides in an acidic vacuole. Salmonella senses this acidic compartment through the action of the EnvZ/OmpR two-component regulatory system. OmpR, in turn, represses the cadC/BA system, preventing neutralization of the bacterial cytoplasm. Read More

Mechanism of reducing knee adduction moment by shortening of the knee lever arm via medio-lateral manipulation of foot center of pressure: A pilot study.

J Biomech 2018 Nov 29. Epub 2018 Nov 29.

Prominent conservative treatment options for medial-compartment knee osteoarthritis include footwear that reduces knee adduction moment (KAM) correlated with detrimental loads in the medial compartment of the knee, thus providing clinical benefit. The proposed mechanism by which they reduce KAM is a lateral shift in foot center of pressure (COP) and a consequent shortening of the knee lever arm (KLA), thereby reducing KAM, which can be simply calculated as KLA multiplied by the frontal plane ground reaction force (FP-GRF). The present study investigated this mechanism for a unique biomechanical device capable of shifting COP by means of moveable convex elements attached to the shoe. Read More
