Resumen
The aim of the research: to optimize the prevention of dental complications by using electromagnetic low-intensity laser radiation (LILR) techniques on dental and periodontal tissues. Research methods. In 138 dental patients, a clinical and functional assessment of the dental apparatus was carried out, dental indices were studied, the results of vascular endothelial parameters (VEGF-A, sVEGF-R1, sVEGF-R2) and immune parameters (FNF, TNF, IFN-γ, neutrophils) of blood serum (solid-phase enzyme immunoassay with a standard set), as well as VAS pain syndrome parameters were analyzed before/after laser therapy of different wavelength, mode and range (red, infrared). Results. The study made it possible to assess the effectiveness of treatment with LILR with one wavelength and in combination of different lengths of laser radiation as independent factors of preventive exposure in dentistry patients. After applying the techniques of transcanal treatment, dental periapical tissues were treated with laser radiation, including root canals (difficult teeth roots), using the C11 attachment from the «Lazmik-01» device. The study used a modulated red spectrum of LILR in continuous and pulsed mode (l = 635 nm) and an infrared pulsed spectrum (l = 904 nm) in a continuous mode with a sequential exposure to red (l = 635 nm) pulsed and infrared continuous laser radiation (l = 904 nm). Emphasis was placed on pain syndrome, vascular endothelial and immune shifts in dental and periodontal tissues before/after using laser therapy in dental patients. Conclusion. The combination of the red spectrum of LILR in pulsed mode (l = 635 nm) with a sequential exposure to infrared laser radiation (l = 904 nm) in continuous mode provides high vascular endothelial responses in the dental and periodontal tissues of the dental apparatus, and the use of red-spectrum laser radiation in continuous mode (l = 635 nm) in dental patients provides antimicrobial and sanitizing effects, including at the level of the root canals, which is more significant than after the use of infrared laser radiation in pulsed mode, when analgesic results are higher.

Resumen
В статье приводятся данные по процессу корнеобразования клюквы болотной в культуре in vitro и ее адаптации к нестерильным условиям. Выявлено благоприятное влияние добавления в питательную среду препарата Экогель в концентрации 0,5 мг/л на процесс ризогенеза клюквы болотной in vitro. Установлена более высокая приживаемость растений при адаптации растений к нестерильным условиям in vivo на субстрате из верхового торфа. One of the most valuable forest crops is marsh cranberry (Oxycoccus palustris Pers.) The article presents data on the adaptation of marsh cranberries to non-sterile conditions, as well as the effect of BMI auxin and Ecogel at the stage of plant rooting in vitro. The research was conducted on the variety of marsh cranberry Dar Kostroma and hybrid 1-15-635. As a result of research, it was found that with an increase in the nutrient medium concentration of AUXIN BMI from 0.5 to 1.0 mg/l, the number of marsh cranberry roots increased on average in the Dar Kostroma variety from 2.4 to 2.7 PCs, and in the hybrid 1-15-635 from 2.1 to 2.4 PCs. When ecogel was added to the Nutrient medium at a concentration of 0.5 mg/l, the number of roots on average reached 3.1 PCs, and without Ecogel it was only 1.7 PCs. It was also noted that the average length of marsh cranberry roots with an increase in the concentration of BMI auxin and the presence of Ecogel in the nutrient medium increased in the Dar Kostroma variety from 1.5 to 2.0 cm, in the 1-15-635 hybrid from 1.3 to 1.5 cm, while without Ecogel it decreased from 1.0 to 0.9 cm and from 1.1 to 0.8 cm, respectively. Adding Ecogel to the nutrient medium at a concentration of 0.5 mg/l increased the average length of cranberry roots by an average of 1.8 times. The total length of marsh cranberry roots, with an increase in the concentration of BMI auxin and the presence of Ecogel in the nutrient medium at a concentration of 0.5 mg/l, increased in the Dar Kostroma variety from 5.1 to 6.0 cm, and in the hybrid 1-15-635 from 4.1 to 4.4 cm, without Ecogel – decreased from 2.6-3.1 to 2.5 cm.

Resumen
The article presents the results of the study of the content of carotenoids of L. sulphureus mycelium under the action of LED lasers: BRP–3010–5, with red spectrum radiation with a wavelength of 635 nm, BBP–3010–5 with blue spectrum radiation with a wavelength of 405 nm and BGP–3010–5 with green spectrum radiation with a wavelength of 532 nm (irradiation energy 51.1 mJ/cm2) when cultured on nutrient medium with different concentrations of glucose. The irradiated mycelium served as a control. It was found that is most effective for the synthesis of carotenoids the use of glucose-peptone medium with a glucose concentration of 10 g/dm³ in combination with irradiation of mycelium with green light at a wavelength of 532 nm (irradiation energy 51.1 mJ/cm2). Under the action of this irradiation regime for strain L.s.-18 the content of carotenoids in the mycelium increased by 66.1% according to the control. Laser irradiation of mycelium with blue light with a wavelength of 405 nm (irradiation energy 51.1 mJ/cm2) increased the content of carotenoids for strain L.s.-18 by 46.7%. Irradiation with red light with a wavelength of 635 nm (irradiation energy 51.1 mJ/cm2) contributed to an increase in the content of carotenoids for strain L.s.-16 of the fungus L. sulphureus by 28.9%. It was found that the use of glucose-peptone medium with a glucose concentration of 8 g/dm3 in combination with irradiation of the mycelium with green light with a wavelength of 532 nm (irradiation energy 51.1 mJ/cm2) was less effective. Under these conditions, the content of carotenoids in the mycelium increased for strain L.s.-17 by 62.3%. Laser irradiation of mycelium with blue light with a wavelength of 405 nm (irradiation energy 51.1 mJ/cm2) increased the content of carotenoids for strain L.s.-17 by 30.6%. Irradiation with red light with a wavelength of 635 nm (irradiation energy 51.1 mJ/cm2) contributed to an increase in the content of carotenoids for strain L.s.-18 of the fungus L. sulphureus by 16.8% respectively. For strain L.s.-16 the number of carotenoids in the mycelium no increase. The use glucose-peptone medium with glucose concentrations of 6 and 4 g/dm3 in combination with laser irradiation of mycelium with red (wavelength 635 nm), blue (wavelength 405 nm) and green (wavelength 532 nm) light with irradiation energy 51.1 mJ/cm2 was no increase in the content of carotenoids in the mycelium.

Resumen
The quality of groundwater should be improved by keeping safe water sources from contaminants in protective way by doing regular measuring and checkup before it supplied for usage. Private Wells do not receive the same services that wells supplying the public do. Well owners are responsible for protecting their drinking water. This work was carried out in Badra city, Iraq from December 2017 to May 2018, six wells water were investigated to determine the general characteristics of wells as well as studying the effect of environmental factors on the quality of water. The average of six wells were eleven parameters that is out of permissible limits were EC, Sal., Alk., TH, TDS, Na, Ca, Cl, SO4, Fe, Zn (4402-5183 /cm, 2.76-3.9 ppt, 302-366mg/L, 3164-4248 mg/L, 604-675 mg/L, 375-524 mg/L, 635-871 mg/L, 631-1107 mg/L, 2430-4570 g/L, 114-392 g/L). Respectively, microbiological investigations involved the total coliform, total plate count, as well as the detection for the presence of E. coli, Salmonella and Cholera. Results shows that there is a significant relation between the increasing of the TDS and Turbidity, TDS gives an indication for the significant increasing of chemical ions. Wells number 3, 4 and 5 showed gave positive results for E.coli growth which as a source of microbial pollution. Detection for the presence of chemical and microbial contaminate is an important alarm since this water has a direct effect on the human and animal's health. Advance method of rapid detection for the well water quality is highly recommended to avoid any health issue and prevent the outbreak of health risk and ecological contaminants.

Resumen
A field experiment was conducted to study the effects of different sowing schedules and planting geometry on yield and productivity of Indian mustard (Brassica juncea L.) var. Giriraj. Among the different sowing schedules, sowing mustard crop on 2nd decade of October was found to produce significantly higher seed and biological yield. The early sowing of mustard crop recorded higher values of utilization and accumulation of various agromet indices like growing degree days (GDD), helio-thermal units (HTU) and photo-thermal units (PTU) as well as higher values of photothermal index (PTI) at different phenological stages than other treatments in comparison. Among the planting geometry significant increase in the seed and biological yield was observed in the plots sown with planting geometry of 30 cm × 10 cm which however was found to be at par with 30 cm × 20 cm. The maximum and minimum temperature and thermal indices at vegetative and reproductive stages had a significant correlation on seed yield of mustard crop during the three years of experimentation. Similarly, heat use efficiency was also significantly related with seed and biological yield of mustard. Bangladesh J. Bot. 51(3): 631-635, 2022 (September)

Resumen
Abstract We describe a colorimetric method for assay of microsomal aminopeptidase (EC 3.4.11.2) activity in serum. We use a new substrate, L-leucyl-3-carboxy-4-hydroxyanilide, p-xylenol as coupler, and sodium metaperiodate as oxidizing reagent. The colored substance formed by the oxidative condensation between p-xylenol and 5-aminosalicylic acid absorbs maximally at 635 nm, and can be directly measured in serum. In a previous method for this enzyme, L-leucyl-beta-naphthylamide was used as substrate and beta-naphthylamine, a carcinogenic reagent used as a standard in making the assay, was unsuitable for routine use. We found a close correlation between results obtained with the new, safer method and with the previous method.

Resumen
ABSTRACT The Ets-1 transcription factor plays a critical role in cell growth and development, but the means by which it activates transcription are still unclear (J. C. Bories, D. M. Willerford, D. Grevin, L. Davidson, A. Camus, P. Martin, D. Stehelin, F. W. Alt, and J. C. Borles, Nature 377:635–638, 1995; N. Muthusamy, K. Barton, and J. M. Leiden, Nature 377:639–642, 1995). Here we show that Ets-1 binds the transcriptional coactivators CREB binding protein (CBP) and the related p300 protein (together referred to as CBP/p300) and that this interaction is required for specific Ets-1 transactivation functions. The Ets-1- and c-Myb-dependent aminopeptidase N (CD13/APN) promoter and an Ets-1-dependent artificial promoter were repressed by adenovirus E1A, a CBP/p300-specific inhibitor. Furthermore, Ets-1 activity was potentiated by CBP and p300 overexpression. The transactivation function of Ets-1 correlated with its ability to bind an N-terminal cysteine- and histidine-rich region spanning CBP residues 313 to 452. Ets-1 also bound a second cysteine- and histidine-rich region of CBP, between residues 1449 and 1892. Both Ets-1 and CBP/p300 formed a stable immunoprecipitable nuclear complex, independent of DNA binding. This Ets-1–CBP/p300 immunocomplex possessed histone acetyltransferase activity, consistent with previous findings that CBP/p300 is associated with such enzyme activity. Our results indicate that CBP/p300 may mediate antagonistic and synergistic interactions between Ets-1 and other transcription factors that use CBP/p300 as a coactivator, including c-Myb and AP-1.

Resumen
Приведены результаты исследований по влиянию освещения разного спектрального диапазона на органогенез растений клюквы болотной сорта Дар Костромы и перспективной гибридной формы 1-15-635 при клональном микроразмножении на этапах «собственно микроразмножение» и «укоренение in vitro». Растения-регенеранты культивировали на питательной среде WPM с добавлением на этапе «собственно микроразмножение» цитокинина 2ip 0,5 мг/л, на этапе «укоренение in vitro» – ауксина ИМК 0,5 мг/л. Для освещения использовали светодиодные лампы белого спектра и с комбинацией белого и красного спектров, а также люминесцентные лампы белого цвета. Выявлено значительное увеличение биометрических показателей растений клюквы болотной in vitro при освещении светодиодными лампами с комбинацией белого и красного спектров: количество микропобегов было почти в 1,9 раза больше, а их суммарная длина – в 4,0–4,2 раза больше, чем при освещении лампами белого спектра. Более мощное развитие надземной части растений клюквы болотной способствовало более интенсивному развитию корневой системы. При освещении надземной части растений лампами с комбинацией белого и красного спектров количество корней было в 1,8–2,5 раза больше, а их суммарная длина – в 2,4–3,5 раза больше, чем при освещении лампами белого спектра. Растения клюквы болотной гибридной формы 1-15-635 формировали более мощные надземную часть и корневую систему, чем у растений сорта Дар Костромы. The results of studies on the effect of illumination of different spectral ranges on the organogenesis of marsh cranberry plants of the Dar Kostroma cultivarand the promising hybrid form 1-15-635 during clonal micropropagation at the stages of “proper micropropagation” and in vitro rooting. Regenerated plants cultivated on a WPM nutrient medium with addition of 2ip 0.5 mg/l at the micropropagation stage, and IMC 0.5 mg/l at the in vitro rooting stage. LED lamps of a white spectrum and with a combination of white and red spectra, as well as white fluorescent lamps are used for lighting. A significant increase in biometric parameters of marsh cranberry plants in vitro is revealed when illuminated with LED lamps with a combination of white and red spectra. The number of microshoots of marsh cranberry under illumination of regenerant plants with LED lamps with a combination of white and red spectra is almost 1.9 times greater, and the total length is 4.0–4.2 times greater than under illumination with white spectrum lamps. More powerful development of the aboveground part of the marsh cranberry plants contributed to the more intensive development of the root system. The number of roots was 1.8–2.5 times greater, and the total length was 2.4–3.5 times greater when the aboveground part of the plants is illuminated with lamps with a combination of white and red spectra than with white lamps. A more powerful aboveground part and root system are formed in marsh cranberry plants of hybrid form 1-15-635 than the Dar Kostroma cultivar.

Resumen
De nombreux sédiments glaciaires déposés à basses latitudes durant le Néoprotérozoïque ont mené à l'hypothèse d'un englacement complet du globe terrestre. La sortie de cet état climatique extrême aurait été engendrée par un effet de serre intense. Ce travail repose sur le croisement d'études sédimentologique, géochimique, magnétique et isotopique sur des sédiments de la plateforme carbonatée d'Araras contemporaine de la transgression postglaciaire Marinoenne. Les résultats révèlent une régression du niveau marin qui atteint son maximum à la fin du dépôt des cap-dolomies, qui est suivit par une période transgressive. Une étude des conditions redox de dépôt basée sur des analyses de concentrations en éléments traces, de minéralogie magnétique et de spéciation du fer, indique des conditions de dépôt oxydantes au sein du sédiment, qui deviennent progressivement réductrices quand la profondeur de dépôt augmente. Les compositions isotopiques en carbone et multi-isotopique du soufre suggèrent que la transgression postglaciaire s'accompagne d'un épuisement de la colonne d'eau en sulfate, du à une augmentation conjointe de la productivité primaire et de la sulfato-réduction bactérienne. Pour l'atmosphère post-Marinoenne, des analyses de compositions isotopiques du carbone des carbonates et de la matière organique qui y est associée ont permis d'estimer une concentration en CO2 maximale de 3200 ppmv. Cette concentration est bien inférieure à celle prédite par les modèles pour permettre la fonte des glaces mais est plus cohérente avec la pO2 atmosphérique attendue pour le Néoprotérozoïque et les conditions de pH des océans favorables à la précipitation des carbonates
The occurrence of low latitude glacial deposits in the Neoproterozoic is the basis of the Snowball Earth hypothesis, which postulates the planet had been completely covered by ice. The recovery from such an extreme climatic state would occur through an extreme greenhouse event. In this thesis we have combined sedimentological studies, geochemistry, magnetic methods and isotopic studies to investigate the Neoproterozoic carbonate platform of Araras, which is correlated to the Marinoan post-glacial successions. Five sections were sampled across the platform. Our results show that the dolomitic succession in the inner shelf sections is deposited in a progressive context, being then covered by transgressive limestones. Redox conditions were deduced from an integrated study, combining trace elements, magnetic mineralogy and iron speciation, which indicate oxic conditions in the shallower facies and relatively more reduced conditions at deeper facies. Multi-isotopic analyses of sulfur and carbon suggest that the end of the glacial event and the post-glacial transgression is accompanied by depletion in the sulfur reservoir, due to the increase in both primary productivity and bacterial sulfate reduction. Carbon isotopic composition of carbonate and associated organic matter in the cap carbonates indicate a maximum CO2 atmospheric concentration of 3200 ppmv. This concentration is coherent with Oa concentrations for the Neoproterozoic and with the ocean pH necessary for the widespread deposition of carbonate successions by that time. Yet, it is significantly lower than that predicted by numerical models of deglaciation

Resumen
Limited water resources and legislation on water abstraction require the adoption of efficient irrigation techniques for sustainable crop production. Partial rootzone drying (PRD) is a technique that allows water use to be optimised through alternate cycles of irrigation to a split root system. A PRD regime and its optimum time of initiation in potatoes that reduces water use and improves water use efficiency with minimal loss in yield were investigated. Hydraulic redistribution mechanism and in-situ root growth responses to PRD were also studied. Potatoes (cv. Estima) were exposed to different irrigation treatments with a control at tuber initiation under polytunnel and glasshouse conditions to identify a suitable PRD regime for potatoes. The treatment which performed most similarly to the control was alternate PRD to field capacity (APRDlOo); one half of the root system was irrigated to field capacity, the other half was allowed to dry to 42 - 45 % of Fe, when irrigation was alternated between the sides. The alternate irrigation was continued until termination of the experiment. There were no significant differences between this treatment and the control for plant growth, gas exchange, leaf water potential and yield. This treatment utilised 29% less water and increased water use efficiency (WUE) by 20% relative to the control. The optimum start time of PRD in potatoes was identified by starting it at two, four, six, eight and ten weeks�·after emergence (WAE). Vegetative growth and yield increased with the delay start of the APRDlOo. When the APRDlOo was started at 6 WAE, greater water savings were seen with increased WUE compared to starting at 8 and 10 WAE but with no yield loss relative to the control. This suggested that the start ofPRD at 6 \VAE was an appropriate time for potatoes. Hydraulic redistribution from wet roots to drying roots within a 24 h period and over three days was investigated using the stable isotope of hydrogen. Hydraulic redistribution occurred the most at night when stomatal conductance was considerably lower and leaf water potential was higher (less negative). The magnitude of the redistributed water did not exceed 3.5%, indicating limited water redistribution under PRD. In-situ root growth responses to PRD showed that PRD plants maintained their root system by slowing down root growth during drying periods but resumed active growth upon re-watering. PRD appears to offer a suitable water saving technique for potato production in glasshouse conditions. Transferring this technique to field conditions, however, will need further research.

Resumen
Somatic embryogenesis is the mass production system of choice for date palm to increase the rates of vegetative propagation. However, the low rates of conversion to plants are common for somatic embryos. Up to 50% of plant productiqn in the Jimmah Tissue Culture Laboratory, Oman is lost during the stages of somatic embryo germination and conversion. Partial desiccation of date palm somatic embryos of the genotype Khalas Aldahra, either by dehydration for up to 4 hours or supplementation of the maturation Murashige and Skoog-based medium with sorbitol, sucrose and polyethylene glycol, increased significantly the percentage conversion to plants. In contrast, the addition of indol-3-butyric acid (IBA), a-naphthaleneacetic acid (NAA), 6-benzylaminopurine (BAP), abscisic acid (ABA), flurprimidol or activated charcoal to the germination medium did not improve the conversion of embryos to plants compared to the control. A protocol for cryopreservation of somatic embryos and embryogenic cultures of the genotype Buhabisha was developed in the current study using the vitrification method (incorporating PVS2 solution) and pretreatment with glycerol, sorbitol and dimethylsulfoxide as a cryoprotectant prior to freezing. Despite the fact that, there was a low percentage of survival of somatic embryos, the results from this study provided evidence that it is possible to cryopreserve somatic embryos and embryogenic callus of Omani date palms. A cell suspension protocol from the genotype Buhabisha was established in this study in order to utlilise more efficient micropropagation methods and to overcome the problems of the large size of somatic embryos that may lead to an efficient cryopreservation technique. NAA gave the best regeneration frequency of somatic embryos compared to 2,4-dichlorophenoxyacetic acid (2,4-D) or picloram. However, attempts to replace activated charcoal in the date palm cultures with either polyvinylpyrolidone or ascorbic acid were unsuccessful. The use of dialysis membrane to separate cell suspensions from activated charcoal was successful, but the generation of somatic embryos was low. Twenty one genotypes obtained from the Jimmah Research Station, Oman were screened and evaluated with microsatelIite markers to establish a DNA fingerprinting procedure. Simple Sequence Repeats (microsatellites) showed that date palm genotypes analysed had high genetic divergence. Importantly, somaclonal variation was not detected by DNA fingerprinting in tissue culture-derived plants of the genotype Khalas Aldahra.

Resumen
The shelf-life of the sweet potato storage root under tropical marketing conditions limits its potential for marketing. This research aimed to identify the physiological characteristics that affect the shelf-life of sweet potato cultivars when they are exposed to tropical marketing conditions. Weight loss was the key limiting factor in storability under the conditions studied. The range in weight loss was large amongst the 39 cultivars tested, and varied between 5 to 15% per week. Weight loss related to the marketable appearance. It consisted mainly of water loss and only 10% was due to respiratory metabolism. Sweet potatoes with high rates of water loss were more susceptible to rotting. The role of periderm characteristics (thickness and permeability), root-size, root surface area/mass ratio and shape were investigated. Although significant differences were observed among cultivars, these characteristics could not account for the variation in storability. The level of damage severely affected the rates of weight loss, with transpiration rate through damaged areas many times higher than through undamaged periderm. Breakage was found to be the most severe form of damage, having a great impact on weight loss for 14 days. Cultivars differed in susceptibility to damage after standardised damage treatments. Susceptibility to breaks was greater for long thin roots. Skinning injury was negatively related to the periderm thickness. Wound healing ability was a major factor for the shelf-life of sweet potato cultivars. It was demonstrated that lignification of wounds as measured by phloroglucinol staining, correlates with reduced susceptibility to weight loss, water loss and microbial attack. A lignin index was used to express the probability that lignification occurs. Cultivars differed significantly in their lignin indices under tropical marketing conditions. A high dry matter content generally coincided with a low lignin index. This relationship was consistent for 19 cultivars tested. Sensory evaluation of five sweet potato cultivars resulted in five distinct sensory profiles. During storage some of the cultivars lost some of their flavour but little changes were observed for textural properties. It was concluded that changes in sensory aspects are not a limiting factor for storage of sweet potato.

Resumen
Potatoes (Solanum tuberosum L.) are the most important food crop in the world after rice and wheat. Potato tubers contain many types of essential nutrients. They contain high concentrations of carbohydrates and also vitamins, minerals and protein. They also contain toxic compounds called glycoalkaloids. Potato is classed as a protective vegetable because of its high vitamin C content. The objectives of this study were to determine the effects of different fertiliser types (composted cattle manure, mineral NPK fertiliser), pre-crop (beans, barley) crop protection protocols (organic, conventional) and growing season on the nutritional quality of vitamin C, glycoalkaloids and minerals and yield of different varieties of potato (Sante, Sarpo Mira, Nicola, Fontane, Agria and Cara). Field experiments were carried out during the 2010 and 2011 growing seasons at Nafferton Farm (Newcastle University). The experiment was a split split split plot-design. The main plot was crop rotation, the sub-plot was crop protection, the sub-sub plot was fertility management and sub-sub-sub plot was variety. The vitamin C content was determined by two different methods of analyses; colorimetric titration and high- performance liquid chromatography (HPLC). Mineral content was assessed by the Dumas combustion method at Sabanci University, Turkey. Total glycoalkaloids were determined according to the AOAC method 997. 13. A significant effect of fertilisation was detected for potato yield for both of years. In plots treated with NPK fertilisers, higher yield, compared to compost was obtained for both seasons. In addition conventional crop protection increased yield in both years. Pre-crop significantly affected yield in both years, with higher yields being recorded after beans than barley in 2010 while, a pre-crop of barley resulted in the significantly higher yield than beans in 2011. However, no significant difference between varieties was detected. Also, no significant interactions were detected for tuber yield in 2010. However a significant 2-way interaction between crop protection and pre-crop was observed in 2011, with a pre-crop of beans resulting in the highest yields under conventional crop protection, while a pre-crop of barley resulted in the significantly higher yield under organic crop protection systems. Results of the second growing season (2011) were based on the NUE potato experiment and showed that there was significant difference (P < 0.05) in yield between varieties, fertilisation iii and crop protection. A significant interaction between fertilisation and variety was detected for the yield. There was a significant effect of variety on tuber vitamin C content (P < 0.001), in 2010 and 2011. The concentrations were higher in Sante than Sarpo Mira. There were no significant influences of other treatments (fertility, rotation, crop protection). However, a 2-way interaction between fertilisation and variety was detected in 2011. In 2011 there was a significant effect of varieties on vitamin C content, but no significant effect of fertility and crop protection treatments. However, a significant interactions between fertility, variety and crop protection treatments was detected but only for the titration analysis for vitamin C content. There were no significant effects (P > 0.05) of fertilisation, pre-crop and crop protection on glycoalkaloid concentrations. However, a significant 3-way interaction between fertilisation, variety and rotation was detected for alpha solanine in 2011. A significant 3-way interaction between crop protection, fertilisation and variety was detected for alpha chaconine in 2010. In 2010 the mineral content (N, P, K, Na and Ca) of potatoes was significantly affected by fertilisation treatments. N, P and Ca contents were significantly increased by NPK application while the K and Na contents were significantly increased by compost application. In 2011 Ca contents were affected by fertilisation treatments only. Effects of variety, rotation and crop protection and interactions between factors were also detected for macro mineral contents. However, in 2011 no effect of pre-crop on tuber macronutrient concentration was detected. There was a significant difference in micronutrient concentration between variety, fertilisation and crop protection. No significant effect of rotations was detected for micronutrient concentrations in both of seasons. In conclusion, in both years, 2010 and 2011, variety significantly affected vitamin C content of potato tubers, but there were no significant effects of fertility, pre-crop and crop protection treatments irrespective of the analytical method (titration and HPLC) analysis. Sante tubers contained about 20% more vitamin C than Sarpo Mira. Therefore, it appears that variety choice is a reliable means of manipulating vitamin C as a component of tuber quality compared with other agronomic treatments. In addition, mineral content was also affected by treatments (fertility, variety, rotation and crop protection) and was highly variable. iv For the two years, similar results were obtained in alpha solanine and alpha chaconine content. Significant interactions between rotation, fertilisation and variety were only detected on alpha solanine content during 2011. Also, significant interactions between variety, fertility and crop protection were observed on alpha chaconine content during 2010. The 2010 and 2011 growing seasons appeared to have a significant effect on alpha solanine, macro minerals and micro minerals but did not appear to affect yield, vitamin C and alpha chaconine contents.

Resumen
Potato (Solanum tuberosum L.) is one of the most economically important crops worldwide for both consumers and farmers; however, it is subjected to huge losses as a result of bacterial, viral and fungal attacks. Therefore, genetic engineering is being used to generate potato crops that are resistant to herbicides, insects and pathogens. It is becoming increasingly apparent that the proteins of the plant cell wall play an important role in the defence of plants against pathogen attacks. Recent studies showed that overexpression of an extensin gene in Arabidopsis conferred considerable resistance to bacterial pathogen attacks. The key objective of this work was to transform Solanum tuberosum L. cv. Desiree potato plants with the Arabidopsis extensin atExt1 gene under the transcriptional control of the strong constitutive CaMV 35S promoter. Stable transformation of the potato genotype Desiree with atExt1 genes was achieved by an Agrobacterium-mediated transformation. The current research also studied the defence response of the overexpressed atExt1 transgenic potato plants by infecting them with Pseudomonas syringae DC3000 and Pectobacterium carotovorum pathogens; and, symptom development was monitored. To investigate if the expression levels of the atExt1 gene in transgenic potato lines have different responses to pathogen infection, two lines of atExt1 transgenic potatoes were tested: the high-level overexpressed atExt1 transgenic line (the transgenic H line) and the low-level overexpressed atExt1 transgenic line (the transgenic L line). This analysis of extensin proteins in plant defence responses provided further evidence to their real function. Pathogenesis analysis within the transgenic H lines showed that the formation of disease symptoms was restricted by inhibiting the colonisation of the pathogens compared with both wild-type potato plants and in the transgenic L line. Furthermore, basal defences and signal transduction pathways involved in plant defence were not perturbed in the transgenic potato lines, as shown by an analysis of the expression of PR-1 and defensin genes. These results show that extensin overexpression in transgenic H potato plants limits pathogen attacks. This is the first study to generate the overexpression of the atExt1 extensin gene in transgenic potato plants and to examine the response of these transgenic lines to bacterial pathogen invasion.

Resumen
Abstract In 1971, Bohley and co-workers [1248] and, in 1972, Kirschke et al. [340] described a new enzyme from rat liver lysosomes which degraded proteins but not synthetic substrates. In 1974 the enzyme was named cathepsin L (in which 'L' stands for lysosomes) by the same authors [343, 1284]. ln 1976 and 1977 cathepsin L was characterized in detail by Kirschke and colleagues [169, 341]. At about the same time, Towatari and co-workers [285, 401] isolated a new cathepsin from rat liver lysosomes which also proved to be cathepsin L. The first indication that this enzyme might be involved in the process of malignant tumour growth came from work in 1978 on the precursor of cathepsin L called major excreted protein (l\1EP) by Gottesman [630]. The name cathepsin L (EC 3.4.22.15) was recommended by the nomenclature committee of IUB in 1978.

Resumen
American cutaneous leishmaniasis (ACL) is one of the most complex parasitic diseases from a clinical-immunopathological point of view due to the great heterogeneity of Leishmania species responsible for the disease. Currently, fifteen Leishmania species of the subgenera Leishmania, Viannia and Mundinia may give rise to ACL in Latin America. In Brazil, seven species are associated to the disease, but L. (V.) braziliensis and L. (L.) amazonensis stand out for producing the broadest clinical-immunopathological spectrum: localized cutaneous leishmaniasis [LCL: DTH+/++], borderline disseminated cutaneous leishmaniasis [BDCL: DTH+/−], mucocutaneous or mucosal leishmaniasis [MCL/ML: DTH++++], and anergic diffuse cutaneous leishmaniasis [ADCL: DTH−]. Although human genetic profile plays important factor in the immunopathogenesis of ACL, it deserves to be highlighted the crucial role of species-specific antigens of L. (V.) braziliensis and L. (L.) amazonensis [lipophosphoglycans, phosphatidylserine, proteophosphoglycans, glycoprotein-63 and CD200 – a macrophage activation inhibitor molecule] in the modulation of T-cell immune response (CD4+/CD8+) that will define the infection evolution.

Resumen
<p>Arched structures have been in use more than three thousand years. The span length of the arch in bridge construction has already exceeded 550 meters. Even longer arch bridges have been designed. The development of arch structures has not been as fast as in cable-stayed bridges during the resent 30 years, when cable-stayed bridges have reached spans more than 1100 m. However, arch structures are becoming more common, especially in bridges.</p><p>The purpose of this paper is to arouse interest in arch structures as well as to open up basic issues related to optimal arch design. The paper discusses the parabolic arch, the catenary arch, and the constant stress arch. The optimum heights, which produce the minimum amount of material, are solved. The importance of form- finding design is emphasized.</p><p>The optimum heights are solved mathematically. In addition, a non-linear iteration procedure, based on vector algebra solution, is used in finding the optimum shape of the moment-less arch. The applications of traditional graphic static and the usage of vector algebra are useful practical tools for designers, especially during the preliminary design stages.</p><p>The maximum theoretical arch spans are remarkably long. At a stress level of 500 MPa, the ultimate span of a steel arch is 19 635 m. The optimal heights of the arches are bigger than traditionally expected. For example, for a parabolic arch, the optimum span to height relation l/h is 2.309. It can also be mentioned that the optimum height ratio of 2.962, derived for the catenary arch, has so far been an unknown figure for designers.</p><p>The theoretical maximal dimensions resolved in the paper indicate that the dimensions of arches can be increased further.</p>

Resumen
On the experimental field of the Center for Small Grains in Kragujevac in the two growing seasons 2018/19 and 2019/20. it was analyzed plant height, lodging resistance and grain yield of 10 genotypes of winter wheat (L-25/6, L-56/98, L- 56/7, L-63/7, L-49 / 4, L-23/24, L-246/2, L-191 / 5-9, L-191 / 5-4 and L-36-2). The average annual temperature and precipitation in both growing seasons were above the multi-year average. The highest average yield during two years had the line L-191 / 5-9 (6,485 t ha-1), then L-246/2 (6,415 t ha-1), and the lowest line L- 63/7 (5,846 t ha -1). Wheat genotypes differed in plant height, so the L-23/24 line had the highest value for this trait in both growing seasons, and the L-25/6 the lowest. In the first vegetation season, a slightly higher plant height ranged from 76 cm to 96 cm, and in the second from 72 cm to 90 cm. All genotypes had good lodging resistance in optimum environments.

Resumen
The database on the content of technogenic radionuclides in the components of the Barents Sea ecosystem in 1992-2020 was analyzed and calculated the transfer coefficients of 137Cs, 90Sr, 239,240Pu from water and bottom sediments to reference organisms. The transition coefficients of 137Cs, 239,240Pu, 90Sr in fish were 93, 262, 12 l/kg, respectively; in shellfish: 51, 1180, 21 l/kg; in marine plants: 69, 732, 19 l/kg; in marine mammals (seals): 63, 222, 14 l/kg. The distribution coefficient of 137Cs between water and bottom sediments was 426 l/kg; by 239,240Pu 189600 l/kg; 90Sr 443 l/kg. The transfer coefficients of technogenic radionuclides from water to fish in the Barents Sea do not have a pronounced trend, which indicates the establishment of an equilibrium in the distribution of radioactivity between the components of the Arctic marine ecosystem.

Resumen
Abstract. This study analyzed the influence of electrolyte composition on the corrosion resistance of plasma electrolytic oxidation (PEO) coatings on EV31 magnesium alloy. An electrolyte solution was prepared by mixing 12 g/l Na3PO4 and various levels of KOH (1, 2, and 4 g/l). The PEO coating was produced with a direct current (DC) regime of 0.05 mA.cm-2 current density and a maximum voltage of 630 V. Electrochemical impedance spectroscopy was performed to assess the corrosion resistance after one hour exposure in 0.1 M NaCl. The results indicated that KOH content has a substantial effect on the morphology and corrosion resistance of the PEO coating and align with previous similar studies. The lowest porosity and highest polarization resistance were observed in the PEO coating prepared with 2 g/l of KOH in the electrolyte, resulting in the best corrosion resistance among the evaluated samples. The presence of only one capacitive loop in the Nyquist diagram and low polarization resistance Rp values of the samples with 4 g/l of KOH in the electrolyte indicated insufficient compactness due to high porosity of the coating.

Resumen
The work deals with the issues of nitrogen and phosphorus removal from wastewater. Natural and modified sorbents: zeolite, glauconite, and bentonite were tested under laboratory conditions. The studies used effluent from biological wastewater treatment that contained an average concentration of 2.2 mg/L of ammonium nitrogen; 7.6 mg/L of nitrate nitrogen and 8.7 mg/L of phosphate phosphorus concentration. Wastewater (0.5 L) was mixed with sorbents (5 g) at a speed of 200 revolutions per minute, then nitrogen and phosphorus concentrations in the solution were measured. Natural glauconite and bentonite removed 58–60% ammonium nitrogen, while modified sorbents show higher 63–70% ammonium nitrogen removal efficiency, respectively. Clinoptilolite removed ammonium nitrogen from wastewater with 76% efficiency. The tested sorbents removed nitrate nitrogen with 14–15% efficiency and phosphate phosphorus with 19–45% efficiency.

Resumen
The Mississippi National River and Recreation area (MISS), situated along a 116 km stretch of the Mississippi River through the Minneapolis and St. Paul urban corridor, encompasses ~21,800 ha of public and private land. In 2022, the Great Lakes Inventory and Monitoring Network (GLKN) resampled permanent forest monitoring sites in the park, marking the second assessment of these sites, which were established and initially sampled in 2011. The goal of this long-term monitoring project is to provides managers with routine updates on which to base management decisions; these data can also be used to tease apart impacts and elucidate causal agents when novel problems or situations arise. We initiated a comprehensive forest monitoring program at MISS in 2011, establishing 33 sites at that time. High water levels during our sampling window that year precluded sampling on many of our planned sites while on others, water levels had only recently subsided. Here, the full complement of herbs had not yet emerged. In 2022, we resampled existing sites and established additional locations, bringing the total to 50. Sampled and derived metrics included trees (density and basal area of live trees, seedlings, and snags (i.e., standing dead trees)), understory (herb and shrub frequency), browse (bite marks on woody species and presence and height of herbaceous species), and taxa richness. We classified sites into four broad forest types using the newer (2022) dataset, resulting in two upland types (upland rich, upland disturbed) and two floodplain types (box elder-dominated and silver maple-dominated). Because of sampling difficulties in 2011, we are only comparing tree, sapling, and snag data between years. At upland rich sites, overall tree (? 2.5 cm diameter at breast height [DBH]) density declined 22%, while that for just the small sapling component (? 2.5 cm, < 5 cm DBH) fell 41%. Species experiencing notable losses include basswood (Tilia americana L.), elm (Ulmus L.), bitternut hickory (Carya cordiformis (Wangenh.) K. Koch), and red oak (Quercus rubra L.). All three resampled sites are located in Spring Lake Park Reserve and subjected to high white-tailed deer (Odocoileus virginianus Zimm.) browse pressure. We sampled seven sites in upland disturbed forests, where overall tree density fell 17% from 778 ? 215 trees/ha to 648 ? 72 trees/ha, largely due to declines in elm, ash (Fraxinus sp. L.), and hackberry (Celtis occidentalis L.). While changes in black cherry (Prunus serotina Ehrh.) mirrored this pattern in diameter classes above 5 cm, density of saplings increased 12-fold, largely due to a swamping effect from one site, possibly in response to buckthorn (Rhamnus cathartica L.) removal. In the nine box elder-dominated sites, overall tree density declined from 635 ? 47 in 2011 to 500 ? 58 trees/ha in 2022, mainly reflecting changes in box elder (Acer negundo L.), elm, and silver maple (Acer saccharinum L.). In these sites, density of large (? 30 cm DBH) snags increased from 2.5 ? 1.6 to 11.1 ? 4.4 snags/ha. In silver maple-dominated floodplain forests, tree density in the 12 sites fell from 421 ? 63 to 291 ? 23 trees/ha, with declines observed in all five dominant species. Sapling density was low in these sites, falling from 62.6 ? 36 in 2011 to 23.6 ? 11 saplings/ha in 2022. Our observations likely reflect both deer browse and alteration of the flow regime by river impoundment. At upland sites, deer browse is impeding regeneration of all major upland species: red oak, bitternut hickory, basswood, and elm. While browse is also occurring in floodplain sites, prolonged inundation may play a larger role in regeneration failure here. Saplings of silver maple, box elder, cottonwood, elm, and hackberry all have some degree of susceptibility to inundation, ranging from moderate tolerance to completely intolerant. The Mississippi River experienced flooding in 2014, 2017, and again in 2019 when flood stage was exceeded for a record number of days in St. Paul. Sapling decline at floodplain sites is likely a direct result of this. Forest management within the park should focus both on invasive species control and floodplain reforestation. Several sites with heavy invasive weed species are in areas where leveraging local volunteers for removal projects may be possible. Floodplain reforestation requires a dual approach of research and active management. Research is needed to determine preferred propagule types and planting stock, as well as the most effective ways to control invasives, especially reed canarygrass (Phalaris arundinacea L.). Active floodplain reforestation can alleviate many of the issues we found here, although this is expensive, limited in scope, and carries with it a great deal of uncertainty. Nonetheless, projects undertaken at a small scale can provide lessons to managers, based on which aspects were successful and which were not. Many of the park forests at MISS are nearing an inflection point and are at risk of becoming irreversibly altered if countermeasures are not undertaken in the near future. At this point, steps taken to promote ecosystem integrity are likely to be less costly and more effective than those which may be needed after further ecosystem decline. The river system through the Twin Cities metro area provides numerous services, both ecological and otherwise. As the need to act is becoming a pressing issue, it is incumbent on land managers to recognize this, and address it.
