Novel sexual dimorphism in a new genus of Bathynellidae from Russia, with a revision of phylogenetic relationships

2019

Bathynellidae is the neglected family of Bathynellacea, a groundwater group of crus- taceans with 33 genera and 107 species described and almost half of them included in the `catch-all¿ genus Bathynella. Due to the morphological homogeneity of the spe- cies, the taxonomic uncertainties have accumulated over time. Therefore, to explore the phylogenetic relationships among taxa, a combined approach using morphologi- cal and molecular data is needed. In this paper, we performed a phylogenetic analysis based on partial sequences of COI and 18S including 30 species of Bathynellidae. This data set represents the most updated one, including a new genus and a new spe- cies (Altainella calcarata gen…

2020

Background To date, microRNAs (miRs) carried in extracellular vesicles (EVs) in response to exercise have been studied in blood but not in non-invasively collectable body fluids. In the present study, we examined whether six exercise-responsive miRs, miRs-21, -26, -126, -146, -221, and -222, respond to acute endurance exercise stimuli of different intensities in sweat. Methods We investigated the response of miRs isolated from sweat and serum EVs to three endurance exercise protocols: (1) maximal aerobic capacity (VO2max ), (2) anaerobic threshold (AnaT), and (3) aerobic threshold (AerT) tests. Sauna bathing was used as a control test to induce sweating through increased body temperature in…

Inserti metrici nel «De eodem et diverso» di Adelardo di Bath

2010

La prima parte del saggio è dedicata alla figura e all’opera di Adelardo di Bath, importante maestro, filosofo e letterato inglese del XII secolo. Alla luce dell’ampia bibliografia, viene ripercorsa la vita e l’attività dello scrittore, soffermandocisi, in particolare, su alcune delle sue opere più significative, quali le «Questiones naturales», il «De avibus tractatus» e gli scritti scientifici e astronomici. Nella seconda parte si indugia invece sul «De eodem et diverso», dialogo d’impostazione “boeziana”. Dell’opera vengono presentati trama e contenuti, viene brevemente analizzata la dedica a Guglielmo vescovo di Siracusa e, nell’ultima sezione del saggio, viene fornita un’ampia e attent…

Rapid Weight Loss Habits before a Competition in Sambo Athletes

2021

Background: Like other combat sports, sambo has competition rules that divide athletes into categories based on gender, age and weight. Athletes in combat sports often resort to rapid weight loss (RWL) methods to be more competitive in lower weight categories and gain an advantage against lighter, smaller and weaker competitors. The aim of this study was to examine the methodology implemented by two different sambo age categories, junior and senior athletes, in order to attain RWL. Methods: The sample consisted of 103 male sambo elite athletes (seniors/juniors: age 28.5 ± 4.3/18.9 ± 0.8

Acute Neuromuscular and Hormonal Responses to Different Exercise Loadings Followed by a Sauna.

2020

Rissanen, JA, Hakkinen, A, Laukkanen, J, Kraemer, WJ, and Hakkinen, K. Acute neuromuscular and hormonal responses to different exercise loadings followed by a sauna. J Strength Cond Res 34(2): 313-322, 2020-The purpose of this study was to investigate acute responses of endurance (E + SA), strength (S + SA), and combined endurance and strength exercise (C + SA) followed by a traditional sauna bath (70° C, 18% relative humidity) on neuromuscular performance and serum hormone concentrations. Twenty-seven recreationally physically active men who were experienced with taking a sauna participated in the study. All the subjects performed a sauna bath only (SA) first as a control measurement follo…

Effects of Rapid Weight Reduction on Force Production and Vertical Jumping Height

1987

The effects of three weight reduction methods on maximal strength, rate of force development, vertical jumping height, and mechanical power were studied in track and field athletes and volleyball players. The three methods were sauna, diet with diuretic, and diuretic alone. The reductions in weight achieved were 3.4%, 5.8%, and 3.8% of body weight after sauna, diet + diuretic, and diuretic, respectively (P less than 0.001). Maximal isometric leg strength and the rate of isometric force development were decreased after the sauna and diet + diuretic treatments. Dehydration caused by the diuretic method alone did not impair neuromuscular performances. As had been expected from theoretical calc…

Acute Hemodynamic Responses to Combined Exercise and Sauna.

2020

AbstractThis study investigated acute hemodynamic, plasma volume and immunological responses to four loading protocols: sauna only, and sauna after endurance, strength or combined endurance and strength exercise. Twenty-seven healthy, slightly prehypertensive men (age 32.7±6.9 years) were measured at PRE, MID (after exercise), POST, POST30min and POST24h. The measurements consisted systolic and diastolic blood pressure, heart rate, body temperature and concentrations of high-sensitive C-reactive protein, white blood cells and plasma volume measurements. Endurance+sauna showed significant decreases in systolic blood pressure at POST (–8.9 mmHg), POST30min (–11.0 mmHg) and POST24h (–4.6 mmHg)…

Sauna Bathing and Risk of Psychotic Disorders : A Prospective Cohort Study

2018

<b><i>Objective:</i></b> Sauna bathing has been suggested to promote mental well-being and relaxation, but the evidence is uncertain with respect to mental disorders. We aimed to assess the association of frequency of sauna bathing with risk of psychosis in the Kuopio Ischemic Heart Disease prospective population-based study. <b><i>Subjects and Methods:</i></b> Baseline sauna bathing habits were assessed in 2,138 men aged 42–61 years who had no history of psychotic disorders. Participants were classified into three groups based on the frequency of sauna bathing (once, 2–3, and 4–7 times per week). <b><i>Results:</i></b>…

ZnO nanorod arrays fabrication via chemical bath deposition: Ligand concentration effect study

2010

A new ligand, N, N, N', N'-tetramethylethylenediamine, has been used to grow ZnO nanorods on silicon substrates via a two steps approach. A preliminary seeding on silicon substrates has been combined with chemical bath deposition using a Zinc acetate - N, N, N', N'-tetramethylethylenediamine aqueous solution. The used diamino ligand has been selected as Zn(2+) complexing agent and the related hydrolysis generates the reacting ions (Zn(2-) and OH(-)) responsible for the ZnO growth. The seed layer has been annealed at low temperature (<200 degrees C) and the ZnO nanorods have been grown on this ZnO amorphous layer. There is experimental evidence that the ligand concentration (ranging from 5 t…

The sedimentary series of upper Bajocian-lower Bathonian age and their organization in the Burgundy threshold and its surroundings. Stratigraphy, sed…

1981

Three fundamental features concerning the organization of the bio-sedimentary series of the upper Bajocian-lower Bathonian of the Burgundy threshold environment are retained:- the formations are organized in a bio-sedimentary platform, composed of three sets: a deep SW platform with clay sedimentation, a superficial NE platform, a transition zone- the geochemical characteristics are consistent with the reconstitution of the NE-NW polarized platform- this device has changed over time: a migration and extension of the surface platform to the SW, development of the transition zone, a slight displacement of the deep platform correlated with a more and more opening towards the SW.
