Major depression has been interpreted as an inflammatory disease characterized by cell-mediated immune activation, which is generally triggered by various stresses. Microglia has been thought to be the cellular link between inflammation and depression-like behavioural alterations. The expression of cathepsin C (Cat C), a lysosomal proteinase, is predominantly induced in microglia in neuroinflammation. However, little is known about the role of Cat C in pathophysiology of depression. In the present study, Cat C transgenic mice and wild type mice were subjected to an intraperitoneal injection of LPS (0...

The C57BL6/J mouse is the most commonly used strain in genetic investigations and behavioural tests. However, only a few studies have used C57BL6/J mice to assess the effects of antidepressant compounds. We carried out a study to compare the behavioural effects of fluoxetine (FLX) in a model of depression in two mice strains: C57BL6/J and BALB/c. We used an 8-week unpredictable chronic mild stress (UCMS) protocol during which FLX was administered (15 mg/kg, oral) from the third week to the end of the protocol...

In April of 2010, the Macondo well blowout in the northern Gulf of Mexico resulted in an unprecedented release of oil into the water column at a depth of approximately 1500 m. A time series of surface and subsurface sediment samples were collected to the northwest of the well from 2010 to 2013 for molecular biomarker and bulk carbon isotopic analyses. While no clear trend was observed in subsurface sediments, surface sediments (0-3 cm) showed a clear pattern with total concentrations of n-alkanes, unresolved complex mixture (UCM), and petroleum biomarkers (terpanes, hopanes, steranes) increasing from May to September 2010, peaking in late November 2010, and strongly decreasing in the subsequent years...

Deep ocean water (DOW) has been shown to enhance the functional components of fungi, resulting in increased health benefits. Therefore, using DOW for culturing fungi can enhance the cordycepin and adenosine of Cordyceps militaris (CM) and its protective effects on the liver. In this study, the antiliver fibrosis effects and mechanisms of ultrapure water-cultured CM (UCM), DOW-cultured CM (DCM), synthetic water-cultured CM, DOW, cordycepin, and adenosine were compared in the liver fibrosis mice induced by intraperitoneal injections of thioacetamide (TAA)...

The immuno-inflammatory activation triggered by various stresses play an important role in pathophysiology of depression. The immune responses display differential pathological characters in different stresses. However, comparative data and analysis on behavioural, inflammatory and neurochemical changes in different stress-induced depression is limited. To imitate different stressful situations, in this study, mice were subjected to a single injection of LPS (0.5mg/kg, i.p.) and UCMS (4 week period), respectively...

Choosing the culture system and culture medium used to produce cells are key steps towards a safe, scalable and cost-effective expansion bioprocess for cell therapy purposes. The use of AB human serum (AB HS) as an alternative xeno-free supplement for mesenchymal stromal cells (MSC) cultivation has increasingly gained relevance due to safety and efficiency aspects. Here we have evaluated different scalable culture systems to produce a meaningful number of umbilical cord matrix-derived MSC (UCM MSC) using AB HS for culture medium supplementation during expansion and cryopreservation to enable a xeno-free bioprocess...

We explored posture-stabilizing multi-muscle synergies with two methods of analysis of multi-element, abundant systems: (1) Analysis of inter-cycle variance; and (2) Analysis of motor equivalence, both quantified within the framework of the uncontrolled manifold (UCM) hypothesis. Data collected in two earlier studies of patients with Parkinson's disease (PD) were re-analyzed. One study compared synergies in the space of muscle modes (muscle groups with parallel scaling of activation) during tasks performed by early-stage PD patients and controls...

Neuronal activity is altered in several neurological and psychiatric diseases. Upon depolarization not only neurotransmitters are released but also cytokines and other activators of signaling cascades. Unraveling their complex implication in transcriptional control in receiving cells will contribute to understand specific central nervous system (CNS) pathologies and will be of therapeutically interest. In this study we depolarized mature hippocampal neurons in vitro using KCl and revealed increased release not only of brain-derived neurotrophic factor (BDNF) but also of transforming growth factor beta (TGFB)...

OBJECTIVE: The present study evaluated the nociceptive response induced by dentin hypersensitivity after dental erosion in rats that were exhibited to unpredictable chronic mild stress (UCMS)-induced depressive-like behavior. DESIGN: Adult male rats were subjected to UCMS (depression [D] group) or not (no depression [ND] group) for 30days and received either acidic solution to induce dental erosion (E) or water (W), thus forming the WND, END, WD, and ED groups. After the end of treatment, depressive-like parameters (i...

Collective behaviors in team sports result in players forming interpersonal synergies that contribute to performance goals. Because of the huge amount of variables that continuously constrain players' behavior during a game, the way that these synergies are formed remain unclear. Our aim was to quantify interpersonal synergies in the team sport of Rugby Union. For that purpose we used the Uncontrolled Manifold Hypothesis (UCM) to identify interpersonal synergies that are formed between ball carrier and support player in two-versus-one situations in Rugby Union...

Older adults are more variable than young adults on tasks that demand the simultaneous control of more than one effector, and the difference between age groups may be related to their different capacity of coordinating the force output of the involved effectors. The goal of this study was to determine whether age-associated differences in motor output variability during tasks involving the simultaneous dorsiflexion of two feet can be partially explained by differences in coordination and possibly attenuated by physical training...

The prefrontal cortex (PFC) is highly sensitive to the effects of stress, a known risk factor of mood disorders including anxiety and depression. Abnormalities in PFC functioning have been well described in humans displaying stress-induced depressive symptoms, and hypoactivity of the PFC is now recognized to be a key feature of the depressed brain. However, little is known about the causes and mechanisms leading to this altered prefrontal functional activity in the context of stress-related mood disorders. We previously showed that unpredictable chronic mild stress (UCMS) in mice increases prefrontal expression of parvalbumin (PV), an activity-dependent calcium-binding albumin protein expressed in a specific subtype of GABAergic neurons, highlighting a potential mechanism through which chronic stress leads to hypofunction of the PFC...

BACKGROUND: Single Nucleotide Polymorphisms (SNPs) are among the most important types of genetic variations influencing common diseases and phenotypes. Recently, some corpora and methods have been developed with the purpose of extracting mutations and diseases from texts. However, there is no available corpus, for extracting associations from texts, that is annotated with linguistic-based negation, modality markers, neutral candidates, and confidence level of associations. METHOD: In this research, different steps were presented so as to produce the SNPPhenA corpus...

BACKGROUND: There are many substances that can interfere with olive oil quality. Some of them are well characterized, but many others have an unknown origin. Saturated hydrocarbons make an extraordinary complex family of numerous molecules, some of them present naturally in vegetable oils. When major natural saturated hydrocarbons are analyzed by standard chromatographic methods, this complex mixture of saturated hydrocarbons appears as a hump in the chromatogram and is commonly named as unresolved complex mixture (UCM) whose origin remains unknown...

A green process and environmentally benign process is highly desirable in the development of enzymatic catalysis. In this work, the shuttle plasmid pHA01 was constructed and the sucrose isomerase (SIase) was expressed in Bacillus subtilis WB800. The optimal nitrogen and carbon sources for SIase expression were yeast extract (15g/L) and un-pretreated cane molasses (UCM, 20g/L), respectively. After the UCM fed, the whole cell activity reached 5.2U/mL in a 7.5L fermentor. Optimum catalytic temperature and pH of whole cell were 35°C and 5...
