(MDPI, 2020)Cell migration is critical for several physiological and pathophysiological processes. It depends on the coordinated action of kinases, phosphatases, Rho-GTPases proteins, and Ca2+ signaling. Interestingly, ubiquitination ...
-
(2001)The postsynaptic density is a highly dynamic structure, which is reorganized in an activity-dependent manner. An animal model for temporal lobe epilepsy, i.e. kainate-induced limbic seizures in rats, was used to study ...
-
(Cambridge University Press, 1996)The molecular karyotypes of several different protozoan parasites show high intra-species variation, including different kinetoplastids such as Trypanosoma brucei, Trypanosoma cruzi and Leishmania ssp. In this study, the ...
-
(Public Library Science, 2015)Formylated peptides are chemotactic agents generated by pathogens. The most relevant peptide is fMLF (formyl-Met-Leu-Phe) which participates in several immune functions, such as chemotaxis, phagocytosis, cytokine release ...
-
(Frontiers Media SA, 2017)In order to establish infection, bacterial pathogens modulate host cellular processes by using virulence factors, which are delivered from the bacteria to the host cell leading to cellular reprogramming. In this context, ...
-
(Wiley, 2020)Transient receptor potential melastatin 4 (TRPM4) is a Ca2+-activated nonselective cationic channel that regulates cell migration and contractility. Increased TRPM4 expression has been related to pathologies, in which ...
-
(Elsevier, 2013)This overview aims to give a brief introduction for clinicians in the wide field of Mind—Body Therapies (MBTs), to summarize the current research status of MBTs in pediatric oncology and to mention challenges for future ...

(Lippincott Williams and Wilkins, 2017)© 2016, the American Society of Anesthesiologists, Inc. Wolters Kluwer Health, Inc. All Rights Reserved.Background: The dissociative general anesthetic ketamine is a well-known N-methyl-d-aspartate receptor antagonist. ...
-
(Taylor & Francis, 2020)Objective: This study aimed to estimate asthma control at specialist treatment centers in four Latin American countries and assess factors influencing poor asthma control. Methods: Patients aged >= 12 years with an asthma ...
-
(Bentham Science Publishers B.V., 2014)In trypanosomatids, redox homeostasis is centered on trypanothione (N 1,N8-bis(glutathionyl)spermidine, T(SH)2), a low molecular weight thiol that is distinctive for this taxonomic family and not present in the mammalian ...
-
(2010)The recognition of conspecifics is a central issue to social behaviour. In eusocial hymenopterans, kin recognition has been clearly demonstrated. Manuelia postica is a largely solitary bee species in which larvae develop ...

(1998)Background: Induction of salivation is becoming increasingly popular in the assessment of salivary gland status. Various mechanical or pharmacological procedures are empirically used to produce salivation. Oral stimulation ...
-
(1984)The kinetic mechanisms of Escherichia coli phosphofructokinase-2 (Pfk-2) and of the mutant enzyme Pfk-2* were investigated. Initial velocity studies showed that both enzymes have a sequential kinetic mechanism, indicating ...
-
(Biophysical Society, 2003)Fast Ca2+ release kinetics were measured in cardiac sarcoplasmic reticulum vesicles actively loaded with Ca2+. Release was induced in solutions containing 1.2 mM free ATP and variable free [Ca2+] and [Mg2+]. Release rate ...
-
(1983)The interaction of Ca2+ and Ba2+ with a Ca2+-activated K+ channel from rabbit skeletal muscle membranes is studied in planar lipid bilayers. At [Ca2+]≥100 µM in the cis side (the side to which the vesicles are added) and ...
-
(ELSEVIER, 2010)Background and purpose: The burden of intracerebral hemorrhage associated with oral anticoagulants (OAC-ICH) is growing. However, little is known about the pathophysiology of W-ICH. Herein,we refine amousemodel of OAC-ICH ...
-
(2012)Deer mice are the principal reservoir hosts of Sin Nombre virus, the etiologic agent of most hantavirus cardiopulmonary syndrome cases in North America. Infection of deer mice results in persistence without conspicuous ...
