Integrating Advanced Visual Information with Ball Projection Technology Constrains Dynamic Interceptive Actions

2014

The role of advanced visual information in ball catching was investigated by integrating video images of action and ball projection technology in four different conditions: Integrated video and ball projection (VBP), Video-Only (VO), Ball Projection-Only (BPO) and Misleading Ball projection (MBP). Hand kinematics and gaze behaviour data were collected from participants who attempted to catch balls one handed in all conditions. During VBP, catching performance was more successful, tracking of the ball occurred earlier and lasted longer, with maximum grip aperture emerging earlier with a slower maximum velocity than in BPO. During VO, movement emerged later than VBP, with larger maximum and m…

Curcumin entrapped into lipid nanosystems inhibits neuroblastoma cancer cell growth and activates Hsp70 protein

2010

Curcumin is a natural anti-cancer compound utilized on a wide variety of human cancer cell lines and animal carcinogenesis models. However, its clinical application has been limited for its minimal systemic bioavailability. Nanoparticle-based drug delivery approaches have the potential for rendering hydrophobic molecules such as curcumin dispersible in aqueous media, thus overtaking the limits of its poor solubility. In this paper, we reported the preparation and chemical-physical characterization of Nanostructured Lipid Carriers (NLC) containing curcumin, based on Imwitor, Compritol or Precirol as lipid matrix. By in vitro experiments, we have demonstrated that these nano-systems are able …

Effect of Acetaldehyde on CRF release form incubated hypothalamic explants

2008

In the past, Acetaldehyde (ACD), the main metabolite of ethanol (ETOH), was mainly studied for its toxic and adverse effects (1). However, recently, ACD was reported to determine behavioural and neurochemical effects, following ETOH assumption in rodents (2, 3). Indeed, ACD enhances dopamine levels in nucleus accumbens, stimulates beta-endorphin release from hypothalamic cells, mediating alcohol reinforcing effects (4). Since little is known about the effects of ACD on other central neuropeptides, in this research we aimed to investigate ACD influence on hypothalamic corticotropin-releasing factor (CRF) release. In order to ascertain this hypothesis, different doses of ACD (1, 10, 3x10 micr…

Eiropas Parlamenta preses relīžu par mazās uzņēmējdarbības stāvokli Eiropas Savienībā stilistiskā analīze

2022

Eiropas Parlaments (EP) ir viena no svarīgākajām lēmējinstitūcijām Eiropas Savienībā. EP plenārsēdēs pieņemtie lēmumi tiek īsi apkopoti preses relīzēs. Šī pētījuma mērķis ir veikt stilistisko analīzi EP preses relīzēm par mazo uzņēmējdarbību, tā kā tai ir īpaši svarīga loma ekonomikā. Galvenās pētniecības metodes ir žanra analīze un stilistiskā analīze. Šis pētījums atklāj EP preses relīžu tipiskās leksiskās, gramatiskās un figurālās iezīmes un definē preses relīzes kā žanru. Tiek secināts, ka EP preses relīžu teikumi ir gari un pakārtoti, un tajos ir ievērojams skaits īpašvārdu, klasificējošo īpašības vārdu, viena vārda leksisko darbības vārdu, abreviatūru un metonīmiju.

Prenatal diazepam exposure functionally alters the GABA(A) receptor that modulates [3H]noradrenaline release from rat hippocampal synaptosomes.

2002

In rats, exposure to diazepam (DZ) during the last week of gestation is associated with behavioral alterations (in some cases sexually dimorphic) that appear when the animals reach adulthood. This study was conducted to evaluate the effects of prenatal DZ exposure on the function of the gamma-aminobutyric (GABA)(A) receptor complex. The method used - perfusion of rat hippocampal nerve terminals labeled with [3H]noradrenaline (NA) - allowed us to evaluate the effects of DZ on a specific native GABA(A) receptor subtype which is located on hippocampal noradrenergic nerve endings and mediates the release of NA. Muscimol stimulated synaptosomal release of [3H]NA in a concentration-dependent mann…

Catch-and-release of Atlantic cod (Gadus morhua): post-release behaviour of acoustically pretagged fish in a natural marine environment

2014

Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, separation of tagging effects from actual C&R effects is required, which is a challenge in the wild, particularly in marine environments. To investigate the effects of C&R on Atlantic cod (Gadus morhua) in their natural environment, 80 cod were caught in fyke nets, fitted with acoustic transmitters, and released. After recovery from tagging and handling for at least 14 days, nine individuals were recaptured and released at least once during experimental angling, fo…

Fluoride release and uptake abilities of different fissure sealants

2016

Background: The long-term capability of resin sealants and glass ionomer cements to release fluoride is associated to a reduction in pit and fissure caries. The regular use of fluoride varnishes/toothpastes can result in the absorption of fluoride into the sealant. The objective of the present study was to assess the fluoride release/uptake capacities of different fissure sealants. Material and Methods: Three different fissure sealants (Fuji Triage/GC, Fissurit FX/Voco and Grandio Seal/Voco) were examined. Ten discs of each material were prepared. Each disc was incubated with distilled water and then the solution analyzed for diluted for fluoride concentration, using a combination of fluori…

Effects of naturally occurring dihydroflavonols from Inula viscosa on inflammation and enzymes involved in the arachidonic acid metabolism

2007

Abstract The anti-inflammatory properties of three flavanones isolated from Inula viscosa , sakuranetin, 7- O -methylaromadendrin, and 3-acetyl-7- O -methylaromadendrin, have been tested both in vitro and in vivo. Acute inflammation in vivo was induced by means of topical application of 12- O -tetradecanoylphorbol 13-acetate (TPA) to mouse ears or by subcutaneous injection of phospholipase A 2 (PLA 2 ) into mouse paws. The test compounds were evaluated in vitro for their effect on both the metabolism of arachidonic acid and on the release and/or activity of enzymes involved in the inflammatory response such as elastase, myeloperoxidase (MPO), and protein kinase C (PKC). The most active comp…
