Aggregation Behavior, Antibacterial Activity and Biocompatibility of Catanionic Assemblies Based on Amino Acid-Derived Surfactants
Abstract: The surface activity, aggregates morphology, size and charge characteristics of binary catanionic mixtures containing a cationic amino acid-derived surfactant N(π), N(τ)-bis(methyl)- L-Histidine tetradecyl amide ...
Orexin-corticotropin-releasing factor receptor heteromers in the ventral tegmental area as targets for cocaine
Release of the neuropeptides corticotropin-releasing factor (CRF) and orexin-A in the ventral tegmental area (VTA) play an important role in stress-induced cocaine-seeking behavior. We provide evidence for pharmacologically ...
Interleukin-16 is increased in obesity and alters adipogenesis and inflammation in vitro
Introduction: Obesity is a chronic condition associated with low-grade</p><p>inflammation mainly due to immune cell infiltration of white adipose tissue</p><p>(WAT). WAT is distributed into two main depots: subcutaneous ...
Role of long non-coding RNAs in adipose tissue metabolism and associated pathologies
The incidence of obesity and its related disorders has increased dramatically in recent years and has become a pandemic. Adipose tissue is a crucial regulator of these diseases due to its endocrine capacity. Thus, understanding ...
Antibacterial and Antiproliferative Activities of Azadirachta indica Leaf Extract and Its Effect on Oil-in-Water Food Emulsion Stability
The present study aims to identify and quantify the phenolic compounds of Azadirachta indica leaf extract using HPLC-MS and to evaluate the antioxidant, antibacterial (against different Gram-positive and negative bacteria) ...
Cocoa and Cocoa Fibre Intake Modulate Reactive Oxygen Species and Immunoglobulin Production in Rats Submitted to Acute Running Exercise
Acute high-intensity exercise can impair the immune system, and lead to oxidative stress. Cocoa intake might help in protecting against oxidative damage and impaired immune functioning. The aim of this study was to establish ...
Mammalian Cell Behavior on Hydrophobic Substrates: Influence of Surface Properties
The influence of different surface properties holding to a modification of the substrate towards hydrophobic or superhydrophobic behavior was reviewed in this paper. Cell adhesion, their communication, and proliferation ...
Angiotensin AT1 and AT2 receptors heteromer expression in microglia correlates with Parkinson's disease progression in the hemilesioned rat model of the disease
Background/Aims : The renin-angiotensin system (RAS) is altered in Parkinson's disease (PD), a disease due to substantia nigra neurodegeneration and whose dopamine-replacement therapy, using the precursor levodopa, leads ...
Healthy Lifestyle Behaviors and Their Association with Self-Regulation in Chilean Children
Background: Self-regulation comprises a series of important competencies, such as the ability to control inner states or responses toward thoughts, attention, emotions, or even performance. The relationship between ...
Com desenvolupar un escaperoom educatiu per a l'aprenentatge d'immunologia: BreakOut Educatiu
Els BreakOut Educatius tenen com a finalitat que l'estudiant aprengui jugant a través de la resolució d'una sèrie d'enigmes que es troben en una caixa o similar. Per introduir continguts d'immunologia s'ha dissenyat un ...
Dietary cobalt supplementation improves growth and body composition and induces the expression of growth and stress response genes in Tor putitora
A 90-day randomized feeding experiment was performed to assess the effects of dietary cobalt (Co) supplementation on the growth performance, muscle composition, status of iron and manganese in the muscle as well as the ...
Synthesis and biological properties of palladium(II) cyclometallated compounds derived from ( E )-2-((4-hydroxybenzylidene)amino)phenol
( E )-2-((4-hydroxybenzylidene)amino)phenol (iminophenol a ) reacted with Pd(OAc) 2 giving place to com- pound 1a , in which the iminophenol was bonded to palladium(II) in a κ3 - C ortho ,N,O ortho tridentate chelat- ing ...
Glucose-6-phosphate dehydrogenase and transketolase modulate breast cancer cell metabolic reprogramming and correlate with poor patient outcome
The pentose phosphate pathway is a fundamental metabolic pathway that provides cells with ribose and NADPH required for anabolic reactions - synthesis of nucleotides and fatty acids - and maintenance of intracellular redox ...
Understanding the role of adenosine A2AR heteroreceptor complexes in neurodegeneration and neuroinflammation
Adenosine is a nucleoside mainly formed by degradation of ATP, located intracellularly or extracellularly, and acts as a neuromodulator. It operates as a volume transmission signal through diffusion and flow in the ...
Enhancement of immune maturation in suckling rats by leptin and adiponectin supplementation
Leptin and adiponectin, adipokines present in breast milk, have shown immunomodulatory properties. The current study aimed to ascertain whether a nutritional supplementation with leptin or adiponectin in neonatal rats was ...
Significant Role of the Truncated Ghrelin Receptor GHS-1Rb in Ghrelin-Induced Signaling in Neurons
The truncated non-signaling ghrelin receptor GHS-R1b has been suggested to simply exert a dominant negative role in the trafficking and signaling of the full and functional ghrelin receptor GHS-R1a. Here we reveal a more ...
Increased inflammation, oxidative stress and mitochondrial respiration in brown adipose tissue from obese mice
Obesity is associated with severe metabolic diseases such as type 2 diabetes, insulin resistance, cardiovascular disease and some forms of cancer. The pathophysiology of obesity-induced metabolic diseases has been strongly ...
Effect of dietary macronutrients on the expression of cholecystokinin, leptin, ghrelin and neuropeptide Y in gilthead sea bream (Sparus aurata)
Endocrine factors released from the central nervous system, gastrointestinal tract, adipose tissue and other peripheral organs mediate the regulation of food intake. Although many studies have evaluated the effect of ...
Grau de satisfacció dels estudiants sobre les activitats complementàries realitzades a l'assignatura Fisiologia i Fisiopatologia III del Grau de Farmàcia de la Universitat de Barcelona
L'avaluació continuada de l'assignatura de Fisiologia i Fisiopatologia III del Grau de Farmàcia es basa en l'acreditació de coneixements assolits en l'estudi autònom i en la realització de tot un seguit d'activitats ...
Study of the process of phagocytosis of corpora amylacea from the cerebrospinal fluid by human macrophages
Corpora Amylacea (CA) are granular bodies that accumulate in the human brain during aging and neurodegenerative conditions. These structures act as containers that amass waste substances from the brain and they are extruded ...
