Authors: Rusyn I. B. , Vakuliuk V. V. , Burian O. V. 
Published: September 2019

Soil plant-microbial biosystems are a promising sustainable technology, resulting in electricity as final product. Soil microbes convert organic products of plant photosynthesis and transfer electrons through an electron transport chain onto electrodes located in soil. This article presents a study of prospects for the generation of bioelectricity by a soil plant-microbial electro-biotechnological system with Caltha palustris L. (Ranunculaceae), a marshy winter-hardy plant that develops early in the spring and is widespread in the moderate climatic zone, in clay-peat medium and with introduction of Lumbricus terrestris L. (Lumbricidae). The experiment was carried out in the wetlands of the Ukrainian Polissya and the Carpathian mountains in situ, and on the balconies and terraces of buildings to assess the possibilities of using green energy sources located directly in buildings. The electrodes were placed stationary in the soil to measure the values of bioelectric potential and current strength. We monitored the bioelectricity indices in open circle and under load using external resistors, and calculated the current density and power density, normalized to the soil surface covered by plants and electrodes. The revealed high maximal values of the bioelectric potential, 1454.1 mV, and current, 11.2 mA, and high average bioelectricity values in optimal natural conditions in wetlands in situ make C. palustris a promising component of soil plant-microbial bio-electrotechnology. We analyzed the influence of temperature and precipitation on the functioning of the soil plant-microbial biosystem. The use of thickets of C. palustris in wetlands in situ, as a stable source of plant-microbial eco-electricity in the summer, is complicated by the fact that the plant sensitively reacts to long periods of high temperature and periods of drought, which is accompanied by decrease in the level of bioelectric parameters. The cultivation of the marsh plant C. palustris as a component of electro-biosystems is possible on terraces and balconies of buildings. The cultivation of C. palustris in clay-peat soil with electrode system for production of eco-electricity on shaded balconies and terraces of buildings requires optimal irrigation, lighting, and introduction of L. terrestris into the substrate, which increase the bioelectricity values of this biotechnology.

Published: September 2019

Adaptation of high-yielding winter wheat crops to changes in climatic conditions has great importance for food security of countries. The remobilization of stem assimilates for grain filling is one of the possible ways of increasing wheat yield in unfavourable environmental conditions. Field experiments in natural conditions with three old and three modern varieties of winter wheat were performed to compare depositing abilities of their stems. The objective of this study was a comparative analysis of the parameters of depositing capacity of stems of the main shoots for identification of the criteria for assessing grain productivity of winter wheat. The parameters of depositing capacity of the stem of the main shoots of three old winter wheat varieties (1997, 2003, and 2008) and three modern ones (2013, 2014 and 2016) were studied in field conditions with natural conditions of water supply (Kyiv Oblast, Ukraine). During the period of formation of reproductive organs (April and May), the amount of precipitation, respectively, was only 17% and 68% of long-term values and average monthly air temperature was 3–4 ºС higher than the climatic norm. We analyzed the variability of the parameters of depositing capacity of the stem of the main shoot and grain productivity of the ear of six wheat winter varieties which differed by time of selection. In unfavourable conditions during the period of formation of reproductive organs the modern winter wheat varieties had an 11% higher yield on average compared to the older ones. It was determined that the highest mass of grain from the ear of the main shoots (1.9–2.1 g) belonged to Odeska 267 variety, a drought-tolerant variety from earlier selection, and three modern varieties – Raihorodka, Prydniprovska and Darunok Podillia. It is demonstrated that these varieties also exceeded two old varieties (Podolianka and Yednist) by stem dry matter weight of main shoot at anthesis by 0.3–0.6 g. The highest content of non-structural carbohydrates at this phase was observed in Odeska 267, Raihorodka and Darunok Podillia varieties (273–307 mg/stem). Correlation analysis revealed the significant correlation between mass of grain from ear and dry matter of stem at anthesis and full ripeness, as well mass of grain from ear and the amount of non-structural carbohydrates at anthesis. Therefore, modern varieties of winter wheat and the drought-tolerant variety have higher yield, weight of dry matter of stem of the main shoot at anthesis and grain productivity of the ear, compared to old varieties. The results of this study indicate that the mass of dry matter of the stem of the main shoot at anthesis can be used as a marker of the grain productivity of winter wheat.

Published: September 2019

The main threat of cancer diseases is their spreading throughout the population of many countries of the world and the complexity of their diagnostics at the early stages. Because of that, search and development of the latest diagnostic methods for oncological diseases which would allow them to be diagnosed more precisely and rapidly is going on. The objective of the study was developing a method for qualitative and quantitative analysis of polyamines as potential tumour markers in blood serum of patients with breast cancer using a newly created immune biosensor based on the effect of surface plasmon resonance (SPR). In the process of the study we used basics of immune analysis, methods of biosensor analysis with preliminary modification of biosensor analytical surface with certain reagents, such as protein A and BSA, for better orientation of the sensitive layer made from antibodies. During the study 30 samples of blood serum were analyzed, 21 of which were obtained from the patients with breast cancer and 9 samples were normal, taken from healthy people and used as controls. Analysis of blood serum samples was made, using previously created calibration curve, based on polyamine solutions in concentrations from 5 ng/mL to 1 µg/mL. It allowed determination of the presence of polyamines in blood samples and approximate concentration of polyamines comparing resonance angle shift in calibration curve and blood samples. According to the obtained results, the concentration of polyamines exceeded their physiological levels and was in the range of 21.3–125.1 ng/mL. The proposed approach allows one to determine the presence and approximate concentrations of polyamines in range from 5 ng/mL to 1 µg/mL in samples of blood serum of patients with breast cancer which correlates with tumour size and the age of the patients.

Abstract: Introduction: Malignant tumours of the sinonasal region – including those with invasion of the skull base – necessitate surgical resection. The majority of the cases give an opportunity to perform the procedure via minimally invasive, endoscopic approach, without external, craniofacial surgery. Aim: To assess our clinical experience in treating anterior skull base malignancies, performing minimally invasive endoscopic transcribriform resection. Method: Between February 2015 and July 2017, four male and one female patient underwent minimally invasive, endoscopic skull base procedure. The mean age was 64.6 years (59–70, median: 66). Every surgery was performed via transnasal, endoscopic transcribriform approach. In two cases Kadish C esthesioneuroblastomas, while in one case a T3N0 sinonasal non-differentiated carcinoma, a T1N0 intestinal type adenocarcinoma and a T4N0 squamous cell carcinoma was the indication of surgery, respectively. Results: The mean follow-up time was 22.8 months, between 14 and 46 months. Intraoperative complications did not occur during the procedures. Regarding the postoperative period, liquorrhoea and pneumocephalus occurred in one case. Complications were solved with lumbar drainage. During follow-up, neither residual nor recurrent tumour was observed in our patients. Conclusion: Endoscopic transcribriform resection of the skull base malignancies is a safe and viable alternative to the traditional open approach. Orv Hetil. 2019; 160(40): 1584–1590.

Abstract: Introduction: Despite advancements in diagnostic capabilities and the availability of effective antimicrobial agents, community-acquired infections of the central nervous system (CNS) are still associated with high mortality rates. Aim: To assess the epidemiological and clinical characteristics of community-acquired CNS infections treated in the West Pannonian region between 2010 and 2016. Method: Clinical data of 176 patients were retrospectively analysed in two age cohorts: 15 to 65 and more than 65 years of age. Results: Neuroinfections were found to be bacterial in 81, viral in 91, parasitic in 1 and mixed in 3 cases during the observation period. The most frequent bacterial pathogens isolated were Streptococcus pneumoniae (20%) and Borrelia burgdorferi (16%). The most frequent viral pathogens isolated were tick-borne encephalitis virus (37%), herpes simplex virus (10%) and enterovirus (7%). Aetiology was unknown in 40 percent of all cases. The average incidence rate was 9.8/100 000 person/year with a mortality rate of 12%. In the cohort of patients aged >65 years, significantly higher frequencies of immunocompromising factors, lower Glasgow Coma Scale values at admission and confusion were observed (p-values: 0.008, 0.017, and 0.050, respectively). Prognosis was negatively influenced by low Glasgow Coma Scale values at admission (OR = 1.6 CI95%: 1.3–1.9; p<0.001), old age (OR = 6.5 CI95%: 2.5–17.1; p<0.001) and immunodeficiency (OR = 3.1 CI95%: 1.2–8.1; p = 0.019). Conclusions: S. pneumoniae remains the most frequently observed causative bacterial pathogen associated with community-acquired CNS infections. Incidence of tick-borne encephalitis in our county is higher than the national average (2.3 versus 0.35/100 000 person/year). Orv Hetil. 2019; 160(40): 1574–1583.
A karbonilstressz szerepe a diabetes szövődményeinek kialakulásában
Authors: Makk-Merczel Kinga , Szarka András 
Published: September 2019

Abstract: The relationship between the potentially developing complications of the 451 million people affected by diabetes and hyperglycaemia can be based on the enhanced generation of advanced glycation endproducts and the more intensive oxidative and carbonyl stress. Advanced glycation endproducts generated partly due to carbonyl stress play an important role in the pathogenesis of diabetic complications such as elevated arterial thickness, vascular permeability, enhanced angiogenesis or the more rigid vessels induced nephropathy, neuropathy, retinopathy. Furthermore, the elevated thrombocyte aggregation, the reduced fibrinolysis induced elevated coagulation, and the atherosclerosis or the mitochondrial dysfunction are important as well. The most potent target of both the non-oxidative and oxidative generation of advanced glycation endproducts can be the scavenging of α,β-unsaturated aldehydes. Although, aminoguanidine, the prototype of scavenger molecules, showed protection in different animal models, it failed in the human clinical studies. Finally, the clinical studies were terminated almost 20 years ago. The endogen dipeptide L-carnosine was also expected to mitigate the complications due to carbonyl stress. However, its clinical significance was limited by the serum carnosinases and by the consequent low serum stability and bioavailability. The carnosinase resistance of the molecule can be achieved by the change of the carboxyl group of the molecule to hydroxyl group. At the same time, the biosafety and the carbonyl stress scavenging activity of the molecule could be preserved. Although clinical studies could not be performed in the last six months, on the basis of the in vitro and in vivo results, carnosinole seems to be a promising compound to mitigate and prevent the diabetic complications. Thus it is worth to the attention of the clinicians. Orv Hetil. 2019; 160(40): 1567–1573.

Abstract: Introduction: Liver cirrhosis (20–25%), hepatocellular carcinoma (1.5–3%), insulin resistance (30–40%) and type 2 diabetes (25–30%) are common complications in patients with chronic hepatitis C virus (HCV) infection; however, data are missing from Hungary. Aim: To determine the prevalence of diabetes and insulin resistance in Hungarian HCV patients; to evaluate treatment-induced metabolic changes in relation to diabetes/insulin resistance and virological response and to perform a sustained follow-up for hepatocellular carcinoma detection. Method: We enrolled 150 Hungarian HCV genotype 1 patients (mean age: 48.55 ± 8.55 years, male/female ratio: 45/55%) from 2007–2012. We analysed their baseline, week 12, and end of therapeutic follow-up (24 weeks after interferon-based therapy completion) laboratory data. We performed a 5-year follow-up (2012–2017). Results: The prevalence of insulin sensitivity, insulin resistance and diabetes was 37.4%, 35.3% and 27.3%, respectively. Insulin resistant and diabetic patients showed a decrease in fasting glucose from baseline to end of follow-up (5.47 ± 0.66 vs. 5.08 ± 0.60, p<0.001; 7.90 ± 2.67 vs. 7.04 ± 2.75, p = 0.006), as did both the sustained responder and non-responder groups. Treatment efficacy rate was poor in diabetic vs. insulin sensitive and insulin resistant groups (17% vs. 46% and 40%); insulin sensitivity was not a predictor of virological response. Three participants with diabetes were diagnosed with hepatocellular carcinoma during follow-up by regular ultrasound examinations. Conclusion: Hungarian HCV patients showed high prevalence of diabetes and insulin resistance, though antiviral therapy caused favourable changes in their carbohydrate metabolism. Antiviral therapy was less effective in diabetic patients. Follow-up ultrasound examinations are required for hepatocellular carcinoma in HCV patients, especially those with diabetes.

Published: September 2019

The purpose of the research reported in this paper was to evaluate the possibility of growing vegetable plants in pots and containers by optimizing the choice of species and cultivars and the type of pot or container based on the information available in the literature and on the basis of our own experience. Taking into account the purpose and objectives of this paper, the study is structured to respond to each bjective considered. Information on crops in pot and containers shows that if the climatic conditions necessary for growth and development areoptimal, basically any vegetable species can be grown in this system (Purnell, 2007). Concerning the pots in which vegetable plants can be grown, they are diverse and may be chosen specifically for this type of culture or can be assigned to provide the space necessary for plant growth for different species.

Published: September 2019

Aim
of study:
Examine patterns in woody species composition, vegetation structure,
precipitation and temperature parameters over two fir forest elevation ranges
and to discuss some biome-climate characteristics.

Area
of Study:
Field sampling was conducted in 20 Abies
forest sites over two elevation ranges (Laguna Juanacatlan and Cerro La Bufa)
in western Jalisco, Mexico.

Material
and Methods: Using linear regressions, relationships between climate and
fir forest structure were inferred. We examined vegetation structure
complemented by cluster and indicator species analyses.

Main
results: A
total of 2378 stems belonging to 67 species were recorded, species richness and
Shannon index were not different between localities. Cluster analysis suggest
three forest types: upper montane cloud forest (UMCF), mixed fir-UMCF and fir
forest. Fir basal area and abundance showed differences between localities.
Reverse J-shaped size distribution pattern was found, except in the Cerro La
Bufa lower belt, where a J-shaped pattern indicates low recruitment and high
number of canopy individuals.

Highlights: The
lower temperatures and increase in winter rainfall along the elevational
gradient, enable an auspicious habitat for western Mexican fir forests.

Amaç: Bu çalışmanın amacı prognozlarını etkileyen faktörleri belirlemeye yönelik olarak servikal dislokasyon tespit edilen hastaların tedavi sonuçlarını incelemektir..Gereç ve Yöntem: Bu çalışmada servikal dislokasyon nedeniyle opere edilen hastaların yaş, cinsiyet, dislokasyon sebebi, “Japanese Orthopedic Association (JOAS)” ölçeği puanı, dislokasyon gelişen omurga seviyesi, faset kilitlenmesi, spondilolistesiz derecesi, cerrahi tedavi bilgileri, yoğun bakım ünitesine (YBU) ve hastane tedavi bilgileri ve hastaneden ayrılış nörolojik düzeylerine ait bilgiler (Modifiye Rankin Skalası, mRS) geriye dönük incelendi.Bulgular: Çalışmaya alınan 13 hastada dislokasyonun çoğunlukla faset kırığına ikincil C5-6 ve C6-7 segmentlerinde oluştuğu görüldü. Çoğu hastada (9 tane) anterior yaklaşımla omurga stabilizasyonu yapıldığı, hastaların %50 kadarında çok seviyeli stabilizasyon uygulandığı saptandı. Korelasyon analizi sonunda JOAS puanları düşük olduğunda spinal şok gelişme olasılığının, ventilatör desteği ihtiyacının, YBU kalma süresinin ve mRS puanlarının artabileceği öngörüldü. Spondilolistezis derecesi arttığında stabilizasyon uygulanan omurga sayısının, ventilatör desteği ihtiyacının, YBU ve hastanede kalma süresinin artabileceği düşünüldü. Spinal şok gelişen hastalarda ventilatör desteği ihtiyacının artabileceği, YBU ve hastanede kalma sürelerinin uzayabileceği ve mRS puanlarının artabileceği varsayıldı. Sonuç: Çalışma sonunda yapılan cerrahi girişimin türünün prognoza etkisinin olmadığı; buna karşılık düşük JOAS puanlarının, spinal şok gelişmesinin, ventilatör desteği verilmesinin, uzun süre yoğun bakım ünitesinde kalmanın hastaların prognozunu kötü etkileyebileceği öngörüldü.

Published: September 2019

Amaç: Karbonmonoksit (CO) zehirlenmesi dünya çapındaki ölümcül intihar veya kazara zehirlenmelerin en yaygın nedenlerinden birisidir. Tanısında spesifik bir biyobelirteç yoktur. Bu sebeple çalışmada CO zehirlenmesinde tam kan parametreleri’nin rolü araştırılmıştır.Gereç ve Yöntem: Çalışmada 1 Ocak 2014 – 1 Ocak 2016 tarihleri arasında acil serviste CO zehirlenmesi tanısı alan ve dışlama kriterlerini sağlayan toplam 442 hasta retrospektif olarak incelendi. Hasta grubunun demografik özellikleri ve tam kan sonuçlarına hastane kayıt sisteminden ulaşıldı. Kontrol grubu acil servise benzer şikâyetler ile başvuran 100 hastadan oluşturuldu. Her iki grubun lökosit (WBC), kırmızı hücre dağılım genişliği (RDW), platelet, lenfosit, nötrofil, nötrofil-lenfosit oranı (NLR) ve platelet-lenfosit oranı (PLR) değerleri istatistiksel olarak karşılaştırıldı. Bulgular: Hasta ve kontrol grubu yaş ve cinsiyet bakımından birbirleri ile benzerdi. Hasta grubunun WBC, RDW, Platelet, Lenfosit, Nötrofil, NLR ve PLR değerleri kontrol grubu ile kıyaslandığında anlamlı derece yüksek bulundu. Ancak hasta yatış süreleri ile Glaskow Koma Skalası (GKS), karboksihemoglobin (COHb), RDW, NLR ve PLR düzeyleri arasında anlamlı bir korelasyon bulunmamıştır.Sonuç: Çalışmamız RDW, NLR ve PLR düzeylerinin CO zehirlenmesi tanısını öngörmede kullanılabilir bir biyobelirteç olma potansiyeli olduğunu düşündürmüştür.
