Sixty three scale insect species are reported from the Mezőföld area (Hungary), a mosaic area of predominantly intensive agricultural land and scattered grassland and forested areas. In comparison, from the Kőrös-Maros National Park, dominated by natural grassland areas, only 31 species were reported. From the Mezőföld data 4 species were new for the Hungarian fauna and almost all species from Mezőföld were new for the given locality. The Mezőföld fauna could be characterised by more rare species and a lower Global Frequency Value (=higher level of species rarity), suggesting a higher overall conservation value. Scale insect species numbers show a strong negative correlation with the ratio of woody plantations. There was an overwhelming presence of a steppic scale insect species in grassland assemblages, and impoverished woody fauna of the studied wooded areas. However, there was no correlation with plant species number, with the area of natural vegetation, or with the area of loess steppe patches, which shows that the original loess step fauna is impoverished, heavily disturbed. In summary we can say, that the Mezőföld loess scale insect fauna is relatively poor, could be characterised by widely distributed, mezophilous, common species. However, it also has several important steppic elements, and therefore deserves protection.

Phosphatase enzymes are capable of releasing phosphate through cleavage of phosphoester bonds. The seasonal importance of this process was examined by using a model substrate paranitrophenylphosphate and the Michaelis-Menten equation to estimate the release rate of PO 4 -P from phosphomonoesters. The seasonal occurrence of phosphomonoesters and acid phosphatase activity was used to estimate the velocity of phosphate release from these compounds. Filter fractionation of phosphatase activity demonstrated that most activity (>60%) was in size fractions less than 0.45 μm. The release rates were highest in May and June (15 to 25 nmol L −1 min −1 ) during the Gonyostomum semen (Raphidophyta) bloom and decreased to less than 2 nmol L −1 min −1 in two weeks and remained low throughout the summer and the fall. Fractionation of 32 P-H 3 PO 4 labelled dissolved organic phosphorus showed this fraction to vary considerably through the year. Potential phosphate release declined through the summer and into the fall. Significance of the co-occurrence of phosphomonoesters and acid phosphatase activity maxima and Gonyostomum semen (Raphidophyta) bloom is discussed.

A Food and Agriculture Organization of the United Nations Technical Cooperation Programme (TCP)was undertaken on the western corn rootworm (WCR)in 1997 –1998 to establish a permanent moni- toring network,evaluate a containment and control program,test the feasibility and effectiveness of using a Slam ®-based areawide pest management program,develop training materials,and conduct a risk assessment of the potential for WCR spread and establishment in other areas of Europe.TCP countries were Bosnia-Her- zegovina,Croatia,Hungary,and Romania.Bulgaria and Yugoslavia cooperated as unofficial TCP members. The data from the permanent monitoring network showed that the WCR had spread over an area of about 105,600 km 2 in Central Europe and that economic populations had developed on 14,000 km 2 in Yugoslavia through 1998.The containment and control trapping program,although designed to determine the feasibility of restricting the establishment of WCR beetles in an area,did not prove to be successful due to the number of WCR beetles encountered and their rapid movement into previously uninfested areas.The areawide pest management activity showed that the semiochemical Slam was highly efficacious against WCR beetles with residual activity for up to 2 weeks,thus making it a cost-effective alternative to other controls.Also, investigations showed that WCR will continue to spread and establish in other parts of Europe.

ICP-OES (inductively coupled plasma optical emission spectrometry) was used to determine the element content of red wines. Development of the method involves various procedures of sample handling as well as repeatability and reproducibility measurements. Measurements were made for the following 16 elements: Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, P, Sr and Zn. The relative standard deviation of repeatability ranged from 0.41% (potassium) to 27% (cadmium) and that of reproducibility varied between 0.73% (boron) to 52% (cobalt). Recovery of the elements was determined by standard addition with results ranging from 90.6% (phosphorus) to 116.2% (boron). After that, 15 red wine samples were measured. Significant differences were found in the Al, B, Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, P, Sr and Zn (P<0.001) concentration of wine samples. Correlation studies revealed parallel changes in phosphorus-potassium, phosphorus-magnesium and zinc-manganese concentrations (r=0.857, 0.875, 0.838). According to principal component analysis, measurements of zinc-, sodium-, boron-, copper- and strontium content gave almost the same results as obtained with 16 different elements. According to a two dimensional non-linear map of absolute values of principal component analysis, wines from Szekszárd and Eger could be differentiated, whereas the analysis of wines from Villány, the Mátra Mountains and Lake Balaton showed overlapping results.

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.

Background

Early repolarization in the anterior ECG leads (ERV2–4) is considered to be a sign of right ventricular (RV) remodeling, but its etiology and importance are unclear.

Methods

A total of 243 top-level endurance-trained athletes (ETA; 183 men and 60 women, weekly training hours: 15–20) and 120 leisure-time athletes (LTA; 71 men and 49 women, weekly training hours: 5–6) were investigated. The ERV2–4 sign was evaluated concerning type of sport, gender, transthoracic echocardiographic parameters, and ECG changes, which can indicate elevated RV systolic pressure [left atrium enlargement (LAE), right atrium enlargement (RAE), RV conduction defect (RVcd)].

Results

Stroke volume and left ventricular mass were higher in ETAs vs. LTAs in both genders (p < 0.01). Prevalence of the ERV2–4 sign was significantly higher in men than in women [p = 0.000, odds ratio (OR) = 36.4] and in ETAs than in LTAs (p = 0.000). The highest ERV2–4 prevalence appeared in the most highly trained triathlonists and canoe and kayak paddlers (OR = 13.8 and 5.2, respectively). Within the ETA group, the post-exercise LAE, RAE, and RVcd changes developed more frequently in cases with than without ERV2–4 (LAE: men: p < 0.05, females: p < 0.005; RAE: men: p < 0.05, females: p < 0.005; RVcd: N.S.). These post-exercise appearing LAE, RAE, and RVcd are associated with the ERV2–4 sign (OR = 4.0, 3.7, and 3.8, respectively).

Conclusions

According to these results, ERV2–4 develops mainly in male ETAs due to long-lasting and repeated endurance training. The ERV2–4 sign indicates RV’s adaptation to maintain higher compensatory pulmonary pressure and flow during exercise but its danger regarding malignant arrhythmias is unclear.

Abstract

We report a case of an infant with spontaneous chylothorax due to the congenital malformation of a small lymph vessel of the chest wall. Conservative therapy with omitting long-chain fatty acids from the diet, fat-free nutrition, total parenteral nutrition and intravenous somatostatin did not result in the decrease of pleural effusion. Thoracic surgical intervention performing thoracic duct ligation and using fibrin sealants was applied after 10 days of unsuccessful conservative therapy, and resulted in the complete recovery of the patient. Our experience support the already existing observations, that in cases where the daily loss of chyle exceeds 100 ml per age years and/or lasts longer than 2 weeks, early surgical intervention is recommended.

Among the factors which determine yield reliability an important role is played by disease resistance. One of the breeding aims in the Martonvásár institute is to develop wheat varieties with resistance to major diseases. The winter wheat varieties bred in Martonvásár are examined in artificially inoculated nurseries and greenhouses for resistance to economically important pathogens. The effectiveness of designated genes for resistance to powdery mildew and leaf rust has been monitored over a period of several decades. None of the designated major resistance genes examined in greenhouse tests is able to provide complete resistance to powdery mildew; however, a number of leaf rust resistance genes provide full protection against pathogen attack (Lr9, Lr19, Lr24, Lr25, Lr28 and Lr35). In the course of marker-assisted selection, efficient resistance genes (Lr9, Lr24, Lr25 and Lr29) have been incorporated into Martonvásár wheat varieties. The presence of Lr1, Lr10, Lr26, Lr34 and Lr37 in the Martonvásár gene pool was identified using molecular markers. New sources carrying alien genetic material have been tested for powdery mildew and leaf rust resistance. Valuable Fusarium head blight resistance sources have been identified in populations of old Hungarian wheat varieties. Species causing leaf spots (Pyrenophora tritici-repentis, Septoria tritici and Stagonospora nodorum) have gradually become more frequent over the last two decades. Tests on the resistance of the host plant were begun in Martonvásár four years ago and regular greenhouse tests on seedlings have also been initiated.

Korábbi vizsgálatok eredményei alapján az érfali tágulékonyság paraméterei összefüggést mutatnak a cardiovascularis mortalitással hemodializált betegekben. A különböző paraméterek relatív prognosztikus értékét ugyanakkor egy közös kohorszban eddig nem vizsgálták. Módszer: Dialízis előtt és után 98 betegnél mértük a carotis-femoralis pulzushullám terjedési sebességét, a carotis augmentációs indexét, a carotis pulzusnyomását és a carotis-brachialis pulzusnyomás amplifikációját. A betegeket 29 hónapig (medián) (tartomány 1–35) követtük, majd a cardiovascularis mortalitás és a kiinduláskor mért tágulékonysági paraméterek közötti összefüggést vizsgáltuk log-rank tesztek, illetve a korhoz, diabeteshez és korábban meglévő cardiovascularis megbetegedéshez illesztett Cox-féle regressziós modellek alkalmazásával. Eredmények: A követés alatt 40 beteg halt meg (mortalitási ráta 20,7/100 betegév), köztük 25-en cardiovascularis ok következtében. A dialízis előtt és után mért pulzushullám-terjedési sebességet tercilisei, illetve a dialízis előtt mért pulzusnyomás-amplifikáció tercilise szignifikáns összefüggést mutattak a cardiovascularis mortalitással (log-rank p-értékek 0,012 és 0,011 a pre- és posztdialízis pulzushullám-terjedési sebesség, illetve <0,001 és 0,321 a pre- és posztdialízis pulzusnyomás-amplifikáció esetén). Az augmentációs indexek, illetve a carotispulzusnyomás-értékek nem álltak összefüggésben a cardiovascularis mortalitással. Cox-modellben az 1 m/s-mal gyorsabb pre- és posztdialízis pulzushullám-terjedési sebességéhez tartozó relatív rizikó 1,24 (1,07–1,44) és 1,17 (1,06–1,28) volt. 10%-kal kisebb predialízispulzusnyomás-amplifikációval járó rizikónövekedés 41% (3–92%) volt. Egy közös modellben vizsgálva mind a predialízispulzushullám-terjedési sebesség, mind a pulzusnyomás-amplifikáció szignifikáns összefüggést mutatott a cardiovascularis túléléssel [relatív rizikó: 1,23 (1,07–1,42) és 1,39 (1,02–1,89)]. Következtetés: Hemodializált betegekben az érfali tágulékonyságot leíró különböző paraméterek közül a pulzushullám-terjedési sebesség a mérés idejétől független, konzekvens összefüggést mutat a cardiovascularis mortalitással. Ugyanakkor a predialízispulzusnyomás-amplifikációs érték további prognosztikus információt hordoz.

Abstract

Breast cancer is characterized by oncobiosis, the abnormal composition of the microbiome in neoplastic diseases. The biosynthetic capacity of the oncobiotic flora in breast cancer is suppressed, as suggested by metagenomic studies. The microbiome synthesizes a set of cytostatic and antimetastatic metabolites that are downregulated in breast cancer, including cadaverine, a microbiome metabolite with cytostatic properties. We set out to assess how the protein expression of constitutive lysine decarboxylase (LdcC), a key enzyme for cadaverine production, changes in the feces of human breast cancer patients (n = 35). We found that the fecal expression of Escherichia coli LdcC is downregulated in lobular cases as compared to invasive carcinoma of no special type (NST) cases. Lobular breast carcinoma is characterized by low or absent expression of E-cadherin. Fecal E. coli LdcC protein expression is downregulated in E-cadherin negative breast cancer cases as compared to positive ones. Receiver operating characteristic (ROC) analysis of LdcC expression in lobular and NST cases revealed that fecal E. coli LdcC protein expression might have predictive values. These data suggest that the oncobiotic transformation of the microbiome indeed leads to the downregulation of the production of cytostatic and antimetastatic metabolites. In E-cadherin negative lobular carcinoma that has a higher potential for metastasis formation, the protein levels of enzymes producing antimetastatic metabolites are downregulated. This finding represents a new route that renders lobular cases permissive for metastasis formation. Furthermore, our findings underline the role of oncobiosis in regulating metastasis formation in breast cancer.
