Venyttelyn akuutit vaikutukset juoksun taloudellisuuteen

2005

Tämän tutkimuksen tarkoituksena oli selvittää ennen suoritusta tehdyn venyttelyn akuutteja vaikutuksia juoksun taloudellisuuteen. Samalla tutkittiin venyttelyn vaikutuksia liikkuvuuteen ja askelmuuttujiin, joten voitiin nähdä ovatko taloudellisuuden mahdolliset muutokset yhteydessä liikkuvuuden tai askelmuuttujien mahdollisiin muutoksiin. Tutkimuksen koehenkilöinä oli 8 miespuolista kestävyysjuoksijaa (ikä 23.9 ± 5.1 vuotta). Jokainen koehenkilö harjoitteli aktiivisesti tulevan kesän kilpailuja varten. Juoksijoiden ennätykset olivat 800m:llä välillä 1min50s – 2min3s ja/tai 1500m:llä välillä 3min53 – 4min5s. Koehenkilöt tekivät samanlaiset juoksun taloudellisuutta mittaavat testit kahtena er…

Estudio de la respuesta antiinflamatoria y antifibrótica de Rilpivirina en células hepáticas no parenquimales

2022

Hoy en día, la infección por el VIH-1 ha pasado de considerarse una enfermedad mortal a convertirse en una condición crónica manejable. Sin embargo, con un tratamiento de por vida y una esperanza de vida cercana a la de la población general, los pacientes con VIH-1 se enfrentan a un mayor riesgo de desarrollar otras patologías crónicas como la enfermedad de hígado graso no alcohólico (NAFLD). Entre los fármacos antirretrovirales empleados para la infección por VIH-1, la Rilpivirina (RPV) está considerada como segura para el hígado y, además, podría ejercer un efecto hepatoprotector. En la presente tesis doctoral se estudió la respuesta antiinflamatoria y antifibrótica inducida por RPV en la…

Detailed modeling of the kraft pulping chemistry : carbohydrate reactions

2020

The article introduces a detailed model for carbohydrate chemistry in kraft pulping. This article is continuation to the modeling work carried out for hot water extraction and chemical pulp bleaching. The model includes galactoglucomannan, xylan, and cellulose acid–base equilibria, in addition to peeling, stopping, and alkaline hydrolysis reactions of the same carbohydrates, as well as hexenuronic acid formation and degradation reactions. The Arrhenius parameters were applied from the literature or regressed against experimental data in the present study. The model is very successful in predicting the experimental data of carbohydrate reactions during kraft pulping. Many features of the pul…

Data from: Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude lakes

2015

Prey preference of top predators and energy flow across habitat boundaries are of fundamental importance for structure and function of aquatic and terrestrial ecosystems, as they may have strong effects on production, species diversity, and food-web stability. In lakes, littoral and pelagic food-web compartments are typically coupled and controlled by generalist fish top predators. However, the extent and determinants of such coupling remains a topical area of ecological research and is largely unknown in oligotrophic high-latitude lakes. We analyzed food-web structure and resource use by a generalist top predator, the Arctic charr Salvelinus alpinus (L.), in 17 oligotrophic subarctic lakes…

Zur Achillessehnenbelastung im alpinen Skisport

1987

In an attempt to gain more systematic knowledge of the biomechanical mechanism involved in the genesis of injuries caused by a fall during skiing, we undertook a comprehensive analysis of more than 100 experimental ski falls simulated under controlled conditions. The well-known relation between speed, release time of the ski binding and injury risk of the lower extremity was confirmed by our experimental results. The EMG investigations revealed the central importance of the musculus triceps surae, and hence of the Achilles tendon, during a fall. The results of our biomechanical model indicate that the present method of setting the ski binding according to the tibial strength, is rather ques…

Serum Levels of Sulpiride Enantiomers after Oral Treatment with Racemic Sulpiride in Psychiatric Patients: a Pilot Study1

2001

Sulpiride (SULP), a substituted benzamide with high selectivity for D 2 -like dopamine receptors, has a chiral structure and is used in most countries as the racemate. In an open pilot study, we investigated 26 inpatients (13 female, 13 male) with schizophrenic or depressive disorder treated with SULP (mean daily dosage 64-1062 mg) administered orally, either as a monotherapy or as an add-on treatment to a stable and unchanged medication for 3-60 days. Serum levels of total SULP and of its enantiomers were measured by high-performance liquid chromatography (HPLC) procedures. Clinically relevant indicators of hepatic and renal function as well as retrospectively assessed clinical outcome par…

Tissue Differences in the Effect of Atropine on the Evoked Release of Acetylcholine

1979

The effect of atropine on the release of acetylcholine (ACh) from different peripheral parasympathetically innervated tissues was investigated. My enteric plexus The longitudinal muscle-myenteric plexus preparation of the guinea-pig was incubated in eserinecontaining Tyrode solution. The ACh release evoked by high K+ (45 or 108 μ) or by the nicotinic drug dimethylphenylpiperazinium (DMPP) (10 pM) was increased by atropine (0.1–10 μ) in a concentration-dependent fashion. Muscarinic agonists (oxotremorine; propargylester of arecaidine) prevented the facilitatory effect of atropine on ACh release. These results suggest that the ACh release from the myenteric plexus is regulated via presynaptic…

Analysis of Rabbit Vascular Responses to DBI, an Ingol Derivative Isolated from Euphorbia canariensis

1997

Abstract We have analysed the effects of 7,12-O-diacetyl-8-O-benzoil-2,3-diepiingol (DBI), an ingol derivative isolated from E. canariensis, on isometric tension developed by isolated rabbit basilar and carotid arteries. Concentration-response curves to DBI (10−8 - 3 × 10−5 m) were obtained cumulatively in both arteries at resting tension and active tone (KC1, 50 mm). At resting tension, DBI induced a concentration-dependent contraction, which was not inhibited in Ca2+-free medium. H7 (1-(5-isoquinoline sulphonyl)-2-methylpiperazine dichloride) (10−4 m) inhibited the DBI-induced contraction both in basilar and in carotid arteries. Calmidazolium (10−4 m) inhibited the maximum contraction of …
