The authors carried out the archaeometric analyses of 9 basalt preforms found at the Kádárta site in Veszprém county. Most of the analyses used non-destructive methods (macroscopic petrography, PGAA, MS and electron-microprobe (EDXEPMA) method developed within the frames of these investigations) and the traditional destructive petrographic and mineral chemical analyses were carried out on a small flake. All the analyses demonstrated that the nine basalt artefacts were prepared from the same raw material. According to the material collected so far from the basalt volcanoes of the Pannonian Basin, this raw material came from the volcanic territory of the Little Hungarian Plain and the Balaton Highlands. Within these territories the most probable provenance of the raw material is the lava rocks in the region of Boncsos-tető, although Hegyestű, Somló and Haláp cannot definitely be excluded.

Abstract

Pace-mapping is an important tool during the ablation of premature ventricular complexes (PVCs) or ventricular tachycardia. The automated pace mapping system software (PaSo module, CARTO XP v9, Biosense/Webster) allows direct comparisons between paced ECGs and the acquired PVC ECG during ablation in a reasonable time. We report our experience with the automated pace mapping system during the ablation of PVCs in the left ventricular outflow tract (LVOT). A 67-year-old male patient was referred to our Department because of recurrent resting atypical chest pain. A 12 lead ECG showed frequent PVCs with LVOT morphology and a 24-hour Holter ECG revealed, that 31% of the total beats were monomorphic PVCs. We decided to perform a radiofrequency catheter ablation. After recording an electroanatomic and an activation map during PVCs, pace-mapping was performed with the PaSo module of the CARTO system. The best percent match area (89.0%) was found in the LVOT, where we performed multiple ablations and PVCs disappeared. According to our initial experience, automated pace-mapping systems might be useful during ablation of PVCs or ventricular tachycardias. Appropriate use of the software allows more objective and faster comparisons compared with conventional manual techniques.

Aims

Right- and left-side-dominant individuals reveal target-matching asymmetries between joints of the dominant and non-dominant upper limbs. However, it is unclear if such asymmetries are also present in lower limb’s joints. We hypothesized that right-side-dominant participants perform knee joint target-matching tasks more accurately with their non-dominant leg compared to left-side-dominant participants.

Methods

Participants performed position sense tasks using each leg by moving each limb separately and passively on an isokinetic dynamometer.

Results

Side-dominance affected (p < 0.05) knee joint absolute position errors only in the non-dominant leg but not in the dominant leg: right-side-dominant participants produced less absolute position errors (2.82° ± 0.72°) with the non-dominant leg compared to left-side-dominant young participants (3.54° ± 0.33°).

Conclusions

In conclusion, right-side-dominant participants tend to perform a target-matching task more accurately with the non-dominant leg compared to left-side-dominant participants. Our results extend the literature by showing that right-hemisphere specialization under proprioceptive target-matching tasks may be not evident at the lower limb joints.

The Ecse-halom is a burial mound (kurgan) in the Hortobágy region of Hungary. Built in the Late Copper Age/Early Bronze Age by nomadic people from the east, it now stands on the border between two modern settlements. A road of medieval origin runs along this border and cuts deeply into the body of the mound. The southern half of the mound was plowed and used as a rice field, and later a military observation tower was built on top of it. Despite this disturbance, the surface of the mound is in decent condition and provides a home for regionally significant, species-rich loess steppe vegetation. The mound comprises two construction layers as indicated by magnetic susceptibility and thin-section micro-morphological analysis. Examination of organic compounds and carbonate content at various levels showed different values, which suggest a variety of natural and anthropogenic stratigraphic layers. Mid-sized siltstone fraction is dominant in the section. The layers originate from the immediate vicinity of the mound, but have different characteristics than present-day soils. These mounds contain a valuable record of cultural and environmental conditions occurring at the time of their construction, and also serve as a refuge for ancient loess vegetation; therefore their conservation is highly recommended.

Aims

The aim of this study was to examine the effects of gender on the relationship between Functional Movement Screen (FMS) and treadmill-based gait parameters.

Methods

Twenty elite junior athletes (10 women and 10 men) performed the FMS tests and gait analysis at a fixed speed. Between-gender differences were calculated for the relationship between FMS test scores and gait parameters, such as foot rotation, step length, and length of gait line.

Results

Gender did not affect the relationship between FMS and treadmill-based gait parameters. The nature of correlations between FMS test scores and gait parameters was different in women and men. Furthermore, different FMS test scores predicted different gait parameters in female and male athletes. FMS asymmetry and movement asymmetries measured by treadmill-based gait parameters did not correlate in either gender.

Conclusion

There were no interactions between FMS, gait parameters, and gender; however, correlation analyses support the idea that strength and conditioning coaches need to pay attention not only to how to score but also how to correctly use FMS.

Foregoing researches made on the N/OFQ system brought up a possible role for this system in cardiovascular regulation. In this study we examined how N/OFQ levels of the blood plasma changed in acute cardiovascular diseases. Three cardiac patient groups were created: enzyme positive acute coronary syndrome (EPACS, n = 10), enzyme negative ACS (ENACS, n = 7) and ischemic heart disease (IHD, n = 11). We compared the patients to healthy control subjects (n = 31). We found significantly lower N/OFQ levels in the EPACS [6.86 (6.21–7.38) pg/ml], ENACS [6.97 (6.87–7.01) pg/ml and IHD groups [7.58 (7.23–8.20) pg/ml] compared to the control group [8.86 (7.27–9.83) pg/ml]. A significant correlation was detected between N/OFQ and white blood cell count (WBC), platelet count (PLT), creatine kinase (CK), glutamate oxaloacetate transaminase (GOT) and cholesterol levels in the EPACS group.Decreased plasma N/OFQ is closely associated with the presence of acute cardiovascular disease, and the severity of symptoms has a significant negative correlation with the N/OFQ levels. We believe that the rate of N/OFQ depression is in association with the level of ischemic stress and the following inflammatory response. Further investigations are needed to clarify the relevance and elucidate the exact effects of the ischemic stress on the N/OFQ system.
