Vector pC3301MCPL carrying coat protein gene with leader sequence, and pC3301MCPS with coat protein gene, were used in Agrobacterium - mediated transformation of sugar beet. The transformation method used was based on the fact that sugar beet develops axillary shoots in in vitro conditions, when placed on media with citokinins. Since this ability is not genotype or ploidy dependant it is widely used for sugar beet vegetative multiplication. Sterile seedlings, with removed cotyledons and lower half of hypocotyl, were used as starting material. After transformation ex-plants were put on micropropagation medium with cephotaxime and phosphinotricyn (ppt, where axillary shoots started to develop. Since concentration of ppt was not selective enough, after two subcultivations it was increased twofold. Only one sample, transformed with pC3301MCPS preserved morphogenetic potential for micropropagatio, and it was tested for presence of COS fragment and bar gene bz PCR with soecific primers.

    Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) is one of the most devastating sugar beet diseases. Sugar beet plants engineered to express a 0.4 kb inverted repeat construct based on the BNYVV replicase gene accumulated the transgene mRNA to similar levels in leaves and roots, whereas accumulation of the transgene-homologous siRNA was more pronounced in roots. The roots expressed high levels of resistance to BNYVV transmitted by the vector, Polymyxa betae. Resistance to BNYVV was not decreased following co-infection of the plants with Beet soil borne virus and Beet virus Q that share the same vector with BNYVV. Similarly, co-infection with the aphid-transmitted Beet mild yellowing virus, Beet yellows virus (BYV), or with all of the aforementioned viruses did not affect the resistance to BNYVV, while they accumulated in roots. These viruses are common in most of the sugar beet growing areas in Europe and world wide. However, there was a competitive interaction between BYV and BMYV in sugar beet leaves, as infection with BYV decreased the titres of BMYV. Other interactions between the viruses studied were not observed. The results suggest that the engineered resistance to BNYVV expressed in the sugar beets of this study is efficient in roots and not readily compromised following infection of the plants with heterologous viruses.

    Full Text Available Rhizomania is one of the most devastating diseases of sugar beet. It is caused by Beet necrotic yellow vein virus (BNYVV transmitted by the obligate root-infecting parasite Polymyxa betae. Beta macrocarpa, a wild beet species widely used as a systemic host in the laboratory, can be rub-inoculated with BNYVV to avoid variation associated with the presence of the vector P. betae. To better understand disease and resistance between beets and BNYVV, we characterized the transcriptome of B. macrocarpa and analyzed global gene expression of B. macrocarpa in response to BNYVV infection using the Illumina sequencing platform.The overall de novo assembly of cDNA sequence data generated 75,917 unigenes, with an average length of 1054 bp. Based on a BLASTX search (E-value ≤ 10-5 against the non-redundant (NR, NCBI protein, Swiss-Prot, the Gene Ontology (GO, Clusters of Orthologous Groups of proteins (COG and Kyoto Encyclopedia of Genes and Genomes (KEGG databases, there were 39,372 unigenes annotated. In addition, 4,834 simple sequence repeats (SSRs were also predicted, which could serve as a foundation for various applications in beet breeding. Furthermore, comparative analysis of the two transcriptomes revealed that 261 genes were differentially expressed in infected compared to control plants, including 128 up- and 133 down-regulated genes. GO analysis showed that the changes in the differently expressed genes were mainly enrichment in response to biotic stimulus and primary metabolic process.Our results not only provide a rich genomic resource for beets, but also benefit research into the molecular mechanisms of beet- BNYV Vinteraction.

    Plant microRNAs (miRNAs) are a class of non-coding RNAs that play important roles in plant development, defense, and symptom development. Here, 547 known miRNAs representing 129 miRNA families, and 282 potential novel miRNAs were identified in Beta macrocarpa using small RNA deep sequencing. A phylogenetic analysis was performed, and 8 Beta lineage-specific miRNAs were identified. Through a differential expression analysis, miRNAs associated with Beet necrotic yellow vein virus (BNYVV) infection were identified and confirmed using a microarray analysis and stem-loop RT-qPCR. In total, 103 known miRNAs representing 38 miRNA families, and 45 potential novel miRNAs were differentially regulated, with at least a two-fold change, in BNYVV-infected plants compared with that of the mock-inoculated control. Targets of these differentially expressed miRNAs were also predicted by degradome sequencing. These differentially expressed miRNAs were involved in hormone biosynthesis and signal transduction pathways, and enhanced axillary bud development and plant defenses. This work is the first to describe miRNAs of the plant genus Beta and may offer a reference for miRNA research in other species in the genus. It provides valuable information on the pathogenicity mechanisms of BNYVV.

    Full Text Available BACKGROUND: Beet necrotic yellow vein virus (BNYVV, encodes either four or five plus-sense single stranded RNAs and is the causal agent of sugar beet rhizomania disease, which is widely distributed in most regions of the world. BNYVV can also infect Nicotiana benthamiana systemically, and causes severe curling and stunting symptoms in the presence of RNA4 or mild symptoms in the absence of RNA4. RESULTS: Confocal laser scanning microscopy (CLSM analyses showed that the RNA4-encoded p31 protein fused to the red fluorescent protein (RFP accumulated mainly in the nuclei of N. benthamiana epidermal cells. This suggested that severe RNA4-induced symptoms might result from p31-dependent modifications of the transcriptome. Therefore, we used next-generation sequencing technologies to analyze the transcriptome profile of N. benthamiana in response to infection with different isolates of BNYVV. Comparisons of the transcriptomes of mock, BN3 (RNAs 1+2+3, and BN34 (RNAs 1+2+3+4 infected plants identified 3,016 differentially expressed transcripts, which provided a list of candidate genes that potentially are elicited in response to virus infection. Our data indicate that modifications in the expression of genes involved in RNA silencing, ubiquitin-proteasome pathway, cellulose synthesis, and metabolism of the plant hormone gibberellin may contribute to the severe symptoms induced by RNA4 from BNYVV. CONCLUSIONS: These results expand our understanding of the genetic architecture of N. benthamiana as well as provide valuable clues to identify genes potentially involved in resistance to BNYVV infection. Our global survey of gene expression changes in infected plants reveals new insights into the complicated molecular mechanisms underlying symptom development, and aids research into new strategies to protect crops against viruses.

  14. Vascular movement of beet necrotic yellow vein virus in Beta macrocarpa is probably dependent on an RNA 3 sequence domain rather than a gene product.

    RNAs 1 and 2 of beet necrotic yellow vein virus (BNYVV) carry the functions enabling viral RNA replication, cell-to-cell movement, virus assembly and vascular movement of the virus in the systemic host Spinacea oleracea. In Beta macrocarpa, on the other hand, BNYVV RNA 3 is required for vascular movement. Replication-competent RNA 3 transcripts carrying various point mutations and deletions were coinnoculated with RNAs 1 and 2 to young leaves of B. macrocarpa and the ability of the virus to multiply on the inoculated leaves and to invade the plant systemically was examined. None of the RNA 3 mutants tested interfered with virus multiplication in the inoculated leaves. Point mutations designed to specifically block or truncate translation of the ORFs of the two known RNA 3 gene products, P25 and N, did not interfere with vascular movement. Vascular movement was not inhibited by deletions eliminating the short 5'-proximal ORF on RNA 3 (ORF A) or by point mutations blocking putative translation of the short 5'-proximal ORF (ORF S) on RNA 3sub, a subgenomic RNA derived from RNA 3. On the other hand, deletions in a 'core region' encompassing nucleotides 1033-1257 of RNA 3 completely blocked vascular movement of the virus while removal of sequences flanking the core region lowered its efficiency. The observations suggest that some feature of the RNA 3 sequence rather than an RNA-3 coded protein is important for vascular movement of BNYVV in B. macrocarpa.

    Full Text Available The reform of the European Union's sugar regime caused potential decreasing beet prices. Therefore, the Speeding Up Sugar Yield (SUSY project was initiated. At the start, a 3 × 15 target was formulated: in 2015 the national average sugar yield in the Netherlands equals 15 t/ha (60% of the sugar beet potential and the total variable costs 15 euro/t sugar beet, aspiring a saving on total variable costs and a strong increase in sugar yield. Based on their average sugar yield in 2000-2004, 26 pairs of “type top” (high yielding and “type average” (average yielding growers were selected from all sugar beet growing regions in the Netherlands. On the fields of those farmers, all measures of sugar beet cultivation were investigated, including cost calculation and recording phytopathological, agronomical and soil characteristics in 2006 and 2007. Although there was no significant difference in total variable costs, the “type top” growers yielded significantly 20% more sugar in each year compared to the “type average” growers. Therefore, the most profitable strategy for the growers is maximizing sugar yield and optimizing costs. The difference in sugar yield between growers could be explained by pests and diseases (50%, weed control (30%, soil structure (25% and sowing date (14%, all interacting with each other. The SUSY-project revealed the effect of the grower's management on sugar yield. As a follow up for the SUSY-project, a growers' guide “Suikerbietsignalen” was published, Best Practice study groups of growers were formed and trainings and workshops were given and field days organized. Further, the benchmarking and feedback on the crop management recordings and the extension on variety choice, sowing performance, foliar fungi control and harvest losses were intensified. On the research part, a resistance breaking strain of the Beet Necrotic Yellow Vein Virus (BNYVV and a new foliar fungus, Stemphylium beticola, were identified

    Full Text Available Sugar beet viruses transmitted by Polymyxa betae are very widespread in the Czech Republic. Beet soil-borne virus (BSBV is present in almost all fields used for sugar beet growing, beet virus Q (BVQ is present in about 50% of fields but beet necrotic yellow vein virus (BNYVV is present in some limited regions only. It means that mixed infections of sugar beet by at least two viruses are quite common in the field. P. betae also occurs in almost all fields where sugar beet is now grown. Only two populations of P. betae not transmitting any virus were found. Cystosori of P. betae can harbour viruses without loosing infectivity for a very long time. We were able to detect these viruses in plants grown in soil stored dry for 12 years. BNYVV can cause serious yield losses under mideuropean conditions reaching up to 50% of sugar yield, whereas harmfulness BSBV and BVQ is questionable, because they also occur in fields with no problems concerning sugar beet growing. The host range of these viruses was studied. Both infect all types of beet (sugar fodder, red beet, mangold and spinach and usually are detectable in root system only. Other chenopodiaceous plants are infected only by some virus strains. These strains are also able to spread into above-ground parts of plants.

    Full Text Available Pathogenic fungi and viruses transmitted by sugar beet seed represent a complex group of organisms. Detection of these pathogens is an important issue in sugar beet protection. Their identification is a difficult task because the most available methods rely on the growth characteristics morphological and biochemical criteria. Three domestic and eight foreign sugar beet varieties, from Germany, Italy and Greece were included in the investigation. Seed health testing was performed in laboratory and in field conditions. During the trials, the following methods were used: blotter method, agar plate method and ELISA test for viruses. Seeds were incubated in "Conviron" aparatus at 22°C which is suitable for sporulation of different kind of fungi (light and temperature were adjustable. The appereance of following fungi was noted during incubation: Pleospora bjoerlingii (Phoma betae, Fusarium spp., Pythium spp. Aphanomyces cochlioides and Cercospora beticola. Viruses tested by ELISA test were beet necrotic yellow vein virus (BNYVV and beet yellows virus (BYV. Viruses were tested in sugar beet seedlings grown in laboratory conditions and on leaves of individual plants from the field. The disease index was calculated on the basis of intensity of infection of plants for Cercospora beticola and Phoma betae according to Mc Kinney's formula. Results were presented by graphs, tables and original photos.

    Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentiation, callus proliferation, and regeneration. Because of the infrequent occurrence of such a genotype in sugar beet populations, our protocol includes an in vitro propagation method for germplasm preservation. The starting materials for transgenic experiments are aseptic shoots grown from surface-sterilized seed balls. Callus is induced from leaf explants and subsequently infected with Agrobacterium. Plantlets are regenerated from transgenic callus and vernalized for flowering, if necessary. The efficiency of transformation was quite high; in our laboratory, the culture of only ten leaf explants, on average, generated one transgenic plant.

    Full Text Available History of present illness: A 71-year-old woman with a history of metastatic ovarian cancer presented with sudden onset, rapidly progressing painful rash in the genital region and lower abdominal wall. She was febrile to 103°F, heart rate was 114 beats per minute, and respiratory rate was 24 per minute. Her exam was notable for a toxic-appearing female with extensive areas of erythema, tenderness, and induration to her lower abdomen, intertriginous areas, and perineum with intermittent segments of crepitus without hemorrhagic bullae or skin breakdown. Significant findings: Computed tomography (CT of the abdominal and pelvis with intravenous (IV contrast revealed inflammatory changes, including gas and fluid collections within the ventral abdominal wall extending to the vulva, consistent with a necrotizing soft tissue infection. Discussion: Necrotizing fasciitis is a serious infection of the skin and soft tissues that requires an early diagnosis to reduce morbidity and mortality. Classified into several subtypes based on the type of microbial infection, necrotizing fasciitis can rapidly progress to septic shock or death if left untreated.1 Diagnosing necrotizing fasciitis requires a high index of suspicion based on patient risk factors, presentation, and exam findings. Definitive treatment involves prompt surgical exploration and debridement coupled with IV antibiotics.2,3 Clinical characteristics such as swelling, disproportionate pain, erythema, crepitus, and necrotic tissue should be a guide to further diagnostic tests.4 Unfortunately, lab values such as white blood cell count and lactate imaging studies have high sensitivity but low specificity, making the diagnosis of necrotizing fasciitis still largely a clinical one.4,5 CT is a reliable method to exclude the diagnosis of necrotizing soft tissue infections (sensitivity of 100%, but is only moderately reliable in correctly identifying such infections (specificity of 81%.5 Given the emergent

It is a leading cause of morbidity and mortality, especially in extremely low birth weight infants. Despite extensive research, the pathophysiology of necrotizing enterocolitis remains unclear and therapeutic options are limited. Multiple risk factors have been reported, but most are associated with prematurity and its complications. This makes management very challenging in vulnerable preterm infants. In this review, we focus on the risk factors and some of the current research in this area, particularly studies aimed at early detection and potential preventive measures for this potentially lethal condition.

    1999-12-01

    In patients with no known systemic disease or immune dysfunction, necrotizing periodontitis (NUP) appears to share many of the clinical and etiologic characteristics of necrotizing ulcerative gingivitis (NUG) except that patients with NUP demonstrate loss of clinical attachment and alveolar bone at affected sites. In these patients, NUP may be a sequela of a single or multiple episodes of NUG or may be the result of the occurrence of necrotizing disease at a previously periodontitis-affected site. The existence of immune dysfunction may predispose patients to NUG and NUP, especially when associated with an infection of microorganisms frequently associated with periodontal disease such as Treponema and Selenomonas species, Fuscobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. The role of immune dysfunction is exemplified by the occasionally aggressive nature of necrotic forms of periodontal disease seen in patients with HIV infection or malnutrition, both of which may impact host defenses. Clinical studies of HIV-infected patients have shown that patients with NUP are 20.8 times more likely to have CD4+ cell counts below 200 cells/mm3. However, these same studies have demonstrated that most patients with CD4+ cell counts below 200 cells/mm do not have NUP, suggesting that other factors, in addition to immunocompromisation, are involved. Further studies are needed to define the complex interactions between the microbial, or viral, etiology of necrotic lesions and the immunocompromised host. It is, therefore, recommended that NUG and NUP be classified together under the grouping of necrotizing periodontal diseases based on their clinical characteristics.

    Necrotizing fasciitis is a rare and severe infection characterised by extremely rapid progressive involvement of the superficial fascias and deep dermal layers of the skin, with resultant vasculitis and necrosis. The authors present three clinical cases of necrotizing fasciitis; all three patients previously had varicella rash, rapid progressive spreading erythema with severe pain and toxic shock syndrome. Two patients had positive cultures of b-haemolytic streptococcus. Early stage differential diagnosis with celulitis, aggressive antibiotic treatment and pediatric intensive care support are essential. However, the main therapy is early extensive surgical approach involving all indurate areas, down to and including the muscle fascia.

    Descendent necrotizing mediastinitis (DNM) is a rare and serious disease with a high mortality. A deep infection in the neck appears generally as the primary focus, as a odontogenic abscess, tonsil infection, pharyngeal or epiglottitis among others. Six cases of descendent necrotizing mediastinitis occurs between January of 1999 to June of 2004 in the hospital santa clara of bogota, colombia, are discussed. Different etiologies were present like odontogenic abscess, submaxillar abscess, retropharyngeal abscess, a cervical esophageal perforation secondary to treatment of a stenosis in the anastomosis between the cenical esophagus and the colon. All of the patients required surgical handling by means of drainage and debridement by cerevicotomy and thoracotomy, and in one case by means of sternotomy, added to antibiotic and intensive care support. Mortality was of 67%, with an average of hospital stay of 17 days

    Sugar beet is a species of the Chenopodiaceae family. It is an important sugar crop that supplies approximately 35% of the sugar in the world. Sugar beet M14 line is a unique germplasm that contains genetic materials from Beta vulgaris L. and Beta corolliflora Zoss. And exhibits tolerance to salt stress. In this review, we have summarized OMICS technologies and applications in sugar beet including M14 for identification of novel genes, proteins related to biotic and abiotic stresses, apomixes and metabolites related to energy and food. An OMICS overview for the discovery of novel genes, proteins and metabolites in sugar beet has helped us understand the complex mechanisms underlying many processes such as apomixes, tolerance to biotic and abiotic stresses. The knowledge gained is valuable for improving the tolerance of sugar beet and other crops to biotic and abiotic stresses as well as for enhancing the yield of sugar beet for energy and food production.

    2014-01-01

    Chloroplast biotechnology has assumed great importance in the past 20 years and, thanks to the numerous advantages as compared to conventional transgenic technologies, has been applied in an increasing number of plant species but still very much limited. Hence, it is of utmost importance to extend the range of species in which plastid transformation can be applied. Sugar beet (Beta vulgaris L.) is an important industrial crop of the temperate zone in which chloroplast DNA is not transmitted trough pollen. Transformation of the sugar beet genome is performed in several research laboratories; conversely sugar beet plastome genetic transformation is far away from being considered a routine technique. We describe here a method to obtain transplastomic sugar beet plants trough biolistic transformation. The availability of sugar beet transplastomic plants should avoid the risk of gene flow between these cultivated genetic modified sugar beet plants and the wild-type plants or relative wild species.

    2013-10-01

    Apoplexy of the pituitary gland is a rare complication of pituitary adenomas, involving hemorrhage with or without necrosis within the tumor. This condition may be either asymptomatic or may present with severe headache, visual impairment, ophthalmoplegia, and pituitary failure. Transsphenoidal surgery is the treatment of choice, and early intervention is usually required to ensure reversal of visual impairment. Reports of pituitary apoplectic lesions exceeding 60.0mm in diameter are very rare. A 39-year-old man with long-standing history of nasal congestion, decreased libido and infertility presented with a sudden onset of severe headache and diplopia. MRI of the head demonstrated a massive skull base lesion of 70.0 × 60.0 × 25.0mm, compatible with a giant pituitary macroadenoma. The lesion failed to enhance after administration of a contrast agent, suggesting complete necrotic apoplexy. Urgent surgical decompression was performed, and the lesion was resected via a transnasal transsphenoidal approach. Pathological analysis revealed evidence of necrotic pituitary apoplexy. At the 2 month follow-up, the patient had near-complete to complete resolution of his visual impairment. To the authors' knowledge, this report is unique as the patient demonstrated complete necrotic apoplexy and it underlines the diagnostic dilemma in such a case. Copyright © 2012 Elsevier Ltd.

    Necrotizing pneumonia causes necrosis of pulmonary parenchyma and may lead to pulmonary gangrene. Prior to the antibiotic era, extensive pulmonary involvement was potentially fatal, but the incidence of necrotizing pneumoniais now less common. On contrast-enhanced CT scans, consolidation with contrast enhancement containing necrotic foci with low attenuation and cavities is characteristic. Radiologic findings do not differ according to the causative organism and in most of cases, specific diagnosis may be impossible. Clinical findings and certain characteristic radiologic findings may be helpful for narrowing the differential diagnosis. We illustrate the clinical and radiologic characteristics of necrotizing pneumonia according to causative bacterial organisms

    Necrotizing fasciitis belongs to a group of complicated soft tissue infections that can be even life threatening. Despite growing knowledge about its etiology, predictors, and the clinical progression, the mortality remains at a high level with 20%. A relevant reduction can be achieved only by an early diagnosis followed by consistent therapy. The clinical findings in about 75% of the cases are pain out of proportion, edema and tenderness, blisters, and erythema. It is elementary to differentiate a necrotizing or a non-necrotizing soft tissue infection early. In uncertain cases it can be necessary to perform a surgical exploration to confirm the diagnosis. The histopathologic characteristics are the fascial necrosis, vasculitis, thrombosis of perforating veins, the presence of the disease-causing bacteria as well as inflammatory cells like macrophages and polymorphonuclear granulocytes. Secondly, both the cutis and the muscle can be affected. In many cases there is a disproportion of the degree of local and systemic symptoms. Depending on the infectious agents there are two main types: type I is a polymicrobial infection and type II is a more invasive, serious, and fulminant monomicrobial infection mostly caused by group A Streptococcus pyogenes.Invasive, severe forms of streptococcal infections seem to occur more often in recent years. Multimodal and interdisciplinary therapy should be based on radical surgical débridement, systemic antibiotic therapy as well as enhanced intensive care therapy, which is sometimes combined with immunoglobulins (in streptococcal or staphylococcal infections) or hyperbaric oxygen therapy (HBOT, in clostridial infections). For wound care of extensive soft tissue defects vacuum-assisted closure has shown its benefit.

    The objective of this study was to determine the mortality rate in patients presenting with Necrotizing Fasciitis. This prospective study was conducted at ward 26, JPMC Karachi over a period of two years from March 2001 to Feb 2003. All patients above the age of 12 years diagnosed to be having Necrotizing Fasciitis and admitted through the Accident and emergency department were included in this study. After resuscitation, the patients underwent the emergency exploration and aggressive surgical debridement. Post-operatively, the patients were managed in isolated section of the ward. The patients requiring grafting were referred to plastic surgery unit. The patients were followed up in outpatients department for about two years. Over all, 25 male and 5 female patients fulfilled the inclusion criteria and were included in this study. The common clinical manifestations include redness, swelling, discharging abscess, pain, fever, skin necrosis and foul smelling discharge etc. The most common predisposing factor was Diabetes mellitus whereas the most commonly involved site was perineum. All patients underwent aggressive and extensive surgical debridements. The common additional procedures included Skin grafting, Secondary suturing, Cystostomy and Orchidectomy. Bacteroides and E. coli were the main micro-organisms isolated in this study. Bacteroides was the most common microorganism isolated among the eight patients who died. Necrotizing Fasciitis is a potentially life threatening emergency condition and carries the mortality rate of about 26.6%. The major contributing factors to increase the mortality missed initially diagnosed, old age, diabetes mellitus truncal involvement and late presentation. Anorectal involvement of disease carry worse prognosis. Hyperbaric oxygen therapy and proper use of unprocessed honey reduced the mortality rate. (author)

    Storage rots represent an economically important factor impairing the storability of sugar beet by increasing sucrose losses and invert sugar content. Understanding the development of disease management strategies, knowledge about major storage pathogens, and factors influencing their occurrence is crucial. In comprehensive storage trials conducted under controlled conditions, the effects of environment and genotype on rot development and associated quality changes were investigated. Prevalent species involved in rot development were identified by a newly developed microarray. The strongest effect on rot development was assigned to environment factors followed by genotypic effects. Despite large variation in rot severity (sample range 0 to 84%), the spectrum of microorganisms colonizing sugar beet remained fairly constant across all treatments with dominant species belonging to the fungal genera Botrytis, Fusarium, and Penicillium. The intensity of microbial tissue necrotization was strongly correlated with sucrose losses (R² = 0.79 to 0.91) and invert sugar accumulation (R² = 0.91 to 0.95). A storage rot resistance bioassay was developed that could successfully reproduce the genotype ranking observed in storage trials. Quantification of fungal biomass indicates that genetic resistance is based on a quantitative mechanism. Further work is required to understand the large environmental influence on rot development in sugar beet.

    2015-12-01

    Probiotics for the prevention of necrotizing enterocolitis have attracted a huge interest. Combined data from heterogeneous randomised controlled trials suggest that probiotics may decrease the incidence of NEC. However, the individual studies use a variety of probiotic products, and the group at greatest risk of NEC, i.e., those with a birth weight of less than 1000 g, is relatively under-represented in these trials so we do not have adequate evidence of either efficacy or safety to recommend universal prophylactic administration of probiotics to premature infants. These problems have polarized neonatologists, with some taking the view that it is unethical not to universally administer probiotics to premature infants, whereas others regard the meta-analyses as flawed and that there is insufficient evidence to recommend routine probiotic administration. Another problem is that the mechanism by which probiotics might act is not clear, although some experimental evidence is starting to accumulate. This may allow development of surrogate endpoints of effectiveness, refinement of probiotic regimes, or even development of pharmacological agents that may act through the same mechanism. Hence, although routine probiotic administration is controversial, studies of probiotic effects may ultimately lead us to effective means to prevent this devastating disease.

    Full Text Available Summary. Priority social problem in the Russian Federation is to provide diverse populations rational healthy diet, taking into account their traditions and economic status. Solving this problem requires the development of processing industries of agriculture on the basis of the improvement of existing and creation of new energy-saving environmentally friendly technologies that can provide deep, if possible without waste, recycling of raw materials. Therefore, the aim of research was the development of technology for production of sugar beet chips. Technology is as follows: sugar beet supplied into the washing machine to remove dirt from its surface. Washed roots inspect on conveyor belts. Next pure sugar beets sent to steam-heat treatment for cleaning the skin. After the beets is subjected to cutting by combining this process with a treatment with an aqueous solution of citric acid. Then he sent for the drying process is completed upon reaching a product of moisture content of 4-5 %. Drying chips feature is that under the high temperature reaction proceeds melanoidins between proteins and sugars present in sugar beet. As a result, the product obtained has the following characteristics: gold-yellow color; absence of a characteristic odor of sugar beet; pleasant sour taste; humidity of 4-5%. Thus, the new technology is relevant, because now the chips are one of the most popular products, ready to eat. A beet chips are rich in dietary fiber (pectin, hemicellulose and cellulose - 4-5 % minerals - macroelements (potassium, sodium, magnesium, calcium, phosphorus, trace elements (iron, zinc, copper, manganese - 0.5-0.6 %, and are the product of a functional food.

    Pollen-mediated gene flow has important implications for biodiversity conservation and for breeders and farmers' activities. In sugar beet production fields, a few sugar beet bolters can produce pollen as well as be fertilized by wild and weed beet. Since the crop, the wild beets, and the weed beets are the same species and intercross freely, the question of pollen flow is an important issue to determine the potential dispersal of transgenes from field to field and to wild habitats. We report here an experiment to describe pollen dispersal from a small herbicide-resistant sugar beet source towards male sterile target plants located along radiating lines up to 1,200 m away. Individual dispersal functions were inferred from statistical analyses and compared. Pollen limitation, as expected in root-production fields, was confirmed at all the distances from the pollen source. The number of resistant seeds produced by bait plants best fitted a fat-tailed probability distribution curve of pollen grains (power-law) dependent on the distance from the pollen source. A literature survey confirmed that power-law function could fit in most cases. The b coefficient was lower than 2. The number of fertilized flowers by background (herbicide-susceptible) pollen grains was uniform across the whole field. Airborne pollen had a fertilization impact equivalent to that of one adjacent bolter. The individual dispersal function from different pollen sources can be integrated to provide the pollen cloud composition for a given target plant, thus allowing modeling of gene flow in a field, inter-fields in a small region, and also in seed-production area. Long-distance pollen flow is not negligible and could play an important role in rapid transgene dispersal from crop to wild and weed beets in the landscape. The removing of any bolting, herbicide-resistant sugar beet should be compulsory to prevent the occurrence of herbicide-resistant weed beet, thus preventing gene flow to wild

    It is very important for the application of chloroplast engineering to extend the range of species in which this technology can be achieved. Here, we describe the development of a chloroplast transformation system for the sugar beet (Beta vulgaris L. ssp. vulgaris, Sugar Beet Group) by biolistic bombardment of leaf petioles. Homoplasmic plastid-transformed plants of breeding line Z025 were obtained. Transformation was achieved using a vector that targets genes to the rrn16/rps12 intergenic region of the sugar beet plastome, employing the aadA gene as a selectable marker against spectinomycin and the gfp gene for visual screening of plastid transformants. gfp gene transcription and protein expression were shown in transplastomic plants. Detection of GFP in Comassie blue-stained gels suggested high GFP levels. Microscopy revealed GFP fluorescence within the chloroplasts. Our results demonstrate the feasibility of engineering the sugar beet chloroplast genome; this technology provides new opportunities for the genetic improvement of this crop and for social acceptance of genetically modified sugar beet plants.

    Full Text Available Introduction. Necrotizing fasciitis is an uncommon condition in general practice but one that provokes serious morbidity. It is characterized by widespread fascial necrosis with relative sparing of skin and underlying muscle. Herein, we report a fatal case of necrotizing fasciitis in a young healthy woman after episiotomy. Case Report. A 17-year-old primigravida underwent a vaginal delivery with mediolateral episiotomy. Necrotizing fasciitis was diagnosed on the 5th postpartum day, when the patient was referred to our tertiary care medical center. Surgical debridement was initiated together with antibiotics and followed by hyperbaric oxygen therapy. The patient died due to septic shock after 16 hours from the referral. Conclusion. Delay of diagnosis and consequently the surgical debridement were most likely the reasons for maternal death. In puerperal period, a physician must consider necrotizing fasciitis as a possible diagnosis in any local sings of infection especially when accompanied by fever and/or tenderness. Early diagnosis is the key for low mortality and morbidity.

    Full Text Available Necrotizing fasciitis is a rapidly progressive infectious disease of the soft tissue with high mortality and morbidity rates. Necrotizing fasciitis is occasionally located in the head and neck region and develops after odontogenic infections. Factors affecting treatment success rates are early diagnosis, appropriate antibiotic treatment, and surgical debridement. We present a necrotizing fasciitis case located in the neck region that developed after sialoadenitis. It is important to emphasize that necrotizing fasciitis to be seen in the neck region is very rare. Nonodontogenic necrotizing fasciitis is even more rare.

  4. BOLTING OF RED BEET: PROBLEMS AND SOLUTIONS

    V. I. Burenin

    2016-01-01

    Full Text Available Results of study of the collection accessions of red beet with different level of bolting resistance are presented. Nature of inheritance of this trait in progeny, and also its connection with other biological and economically valuable characters and properties is shown. Bolting resistant accessions and possibility of its use in breeding are described. The promising initial material is selected and recommended. The most rational solution of the bolting problems in the beet is the development of resistant varieties and hybrids. For this purpose, the early-spring and under-winter planting are used, as well as the seed germination at low (30C temperatures. The availability of the various initial material studied by modern methods of researches plays a key role. When the collection accessions of beet were studied in the VIR Polar branch (The Murmansk Region, the following genotypes were identified: 1 – non bolting, 2 – weak bolting (less than 10% of bolting plants, 3 – moderately bolting (10-50%, and 4 – high bolting (more than 50% of bolting plants. As a result of screening of a gene pool, the genetic sources of bolting resistance of beet were identified. At its crossing with bolting accessions the dominance of the trait «bolting» and monogenic nature of its inheritance are confirmed. For the purpose of beet breeding for bolting resistance, the symphycarpous varieties characterized by complex biological and agronomic characters (increased yield, cold tolerance, quality of production and resistance to blackleg are the most usable. The cultivars Banko from Sweden (donor, Podzimnyaya A-0474 (VNIISSOK and Polyarnaya ploskaya-249 (Polar branch VIR are recommended as a genetic sources of bolting resistance.

    Full Text Available Victoria A Bendersky,1 Mohan K Mallipeddi,2 Alexander Perez,2 Theodore N Pappas,2 1School of Medicine, 2Department of Surgery, Duke University, Durham, NC, USA Abstract: Acute pancreatitis is a common disease that can progress to gland necrosis, which imposes significant risk of morbidity and mortality. In general, the treatment for pancreatitis is a supportive therapy. However, there are several reasons to escalate to surgery or another intervention. This review discusses the pathophysiology as well as medical and interventional management of necrotizing pancreatitis. Current evidence suggests that patients are best served by delaying interventions for at least 4 weeks, draining as a first resort, and debriding recalcitrant tissue using minimally invasive techniques to promote or enhance postoperative recovery while reducing wound-related complications.

    Necrotizing fasciitis (NF) is a rare, life-threatening soft-tissue infection and a medical and surgical emergency, with increasing incidence in the last few years. It is characterized by a rapidly spreading, progressive necrosis of the deep fascia and subcutaneous tissue. Necrotizing fasciitis is often underestimated because of the lack of specific clinical findings in the initial stages of the disease. Many adjuncts such as laboratory findings, bedside tests - e.g., the ''finger test'' or biopsy - and imaging tests have been described as being helpful in the early recognition of the disease. Imaging is very useful to confirm the diagnosis, but also to assess the extent of the disorder, the potential surgical planning, and the detection of underlying etiologies. The presence of gas within the necrotized fasciae is characteristic, but may be lacking. The main finding is thickening of the deep fasciae due to fluid accumulation and reactive hyperemia, best seen on magnetic resonance imaging. (orig.)

    Full Text Available History of Present Illness: A 34-year-old HIV positive female presented to the emergency department with a three-week history of swollen, painful gums. She had difficulty eating and chewing, along with aches and general malaise. The patient was an everyday smoker and was not taking any antiretroviral medication. Significant findings: Physical examination revealed inflamed gingiva, ulceration, and soft tissue necrosis (Image 1 along with mandibular lymphadenopathy (not shown. Given her symptoms, poor oral care, and her immunocompromised state, she was given a diagnosis of Acute Necrotizing Ulcerative Gingivitis (ANUG or Vincent’s Angina. Discussion: Acute Necrotizing Ulcerative Gingivitis (ANUG, Vincent’s Angina, or Trench Mouth is the only periodontal disease in which bacteria invade non-necrotic tissue. The etiology is usually secondary to fusobacteria and spirochete overgrowth of bacteria which is normally present in the oral cavity. HIV infection, previous necrotizing gingivitis, poor oral hygiene, malnutrition, smoking, and stress are predisposing factors. Antibiotics and improved nutrition have significantly decreased the incidence of ANUG. The prevalence of ANUG among HIV infected patients varies from 4.3% to 16.0%. ANUG is 20.8 times more likely to be seen in AIDS patients with CD4 counts less than 200 cells/mm3. In developing countries, like those in Sub-Saharan Africa, incidence of ANUG is increasing among children with a prevalence as high as 23% in children under 10 years of age.1 Treatment for ANUG is multifactorial. Patients need good debridement under anesthesia so dental referral is imperative. Pain control with Ibuprofen or low dose opioids is indicated. Oral hygiene instructions include Chlorhexidine 0.12% twice daily, proper nutrition, appropriate fluid intake, and smoking cessation. For signs of systemic involvement, the recommended antibiotics are Amoxicillin and Metronidazole.2 If left untreated, ANUG may lead to rapid

    The objective of this paper was to apply terahertz (THz) spectroscopy combined with chemometrics techniques for discrimination of genetically modified (GM) and non-GM sugar beets. In this paper, the THz spectra of 84 sugar beet samples (36 GM sugar beets and 48 non-GM ones) were obtained by using terahertz time-domain spectroscopy (THz-TDS) system in the frequency range from 0.2 to 1.2 THz. Three chemometrics methods, principal component analysis (PCA), discriminant analysis (DA) and discriminant partial least squares (DPLS), were employed to classify sugar beet samples into two groups: genetically modified organisms (GMOs) and non-GMOs. The DPLS method yielded the best classification result, and the percentages of successful classification for GM and non-GM sugar beets were both 100%. Results of the present study demonstrate the usefulness of THz spectroscopy together with chemometrics methods as a powerful tool to distinguish GM and non-GM sugar beets.

    Full Text Available During the seed crop growing there can be also problems with uncontrolled pollination if in the previous years there was seed shedding during the harvest, which can cause growth and flowering of diploid, triploid and tetraploid plants and that can present serious problem for the next sugar beet seed crop. Meiosis of triploid hybrids is irregular and can result in development of gametes with different chromosome number. Sugar beet triploids in metaphase I have 9 univalents and 9 bivalents and therefore can be source of aneuploid gametes. After cytological analysis that was performed on 2124 meiocytes, in 14.64% different types of irregularities were detected, such as dislocated chromosomes and chromosome bridges.

The seeding system is characterized by a deep loosening of soil with a tine combined with a share and by following tools generating fine-grained soil as seed bed. In cooperation with the Kverneland company group Soest/Germany a strip tiller combined with precision seeder was designed and tested in field experiments. Tilling and seeding was performed in one path on fields with straw and mustard mulch. Even the plant development was slower as compared to conventional sawn sugar beets the yield was on equivalent level. Further field experiments are planned to attest constant yield, cost and energy efficiency of the seeding system.

    Full Text Available Production values of 43 experimental and recognized sugar beet hybrids were conducted on the Zagreb location in the period 2003-2005. The trials included hybrids from six breeding institutions that sell sugar beet seed in the Republic of Croatia. Research results have revealed significant differences in yields and root quality among inve- stigated sugar beet hybrids. However, the results of a large number of hybrids were equal in value; namely, the dif- ference between them was within the statistically allowable deviation. The hybrids KW 0148 HR and Buda in 2003, Sofarizo and Takt were distinguished by high sugar yields in 2004, whereas Merak, Impact and Europa in 2005. The highest root yields were recorded for hybrids Dioneta, Buda and KW 0148 HR in 2003, Sofarizo, Takt, HI 0191 and Dorotea in 2004, Impact and SES 2371 in 2005. The highest root sugar contents were determined in hybrids Zita and Evelina in 2003, Cyntia, Diamant and Belinda in 2004, and Merak, Belinda and Cyntia in 2005.

    Full Text Available In this investigation, the production of ethanol from the raw sugar beet juice and raw sugar beet cossettes has been studied. For ethanol production from the raw sugar beet juice, batch and fed-batch cultivation techniques in the stirred tank bioreactor were used, while batch ethanol production from the raw sugar beet cossettes was carried out in horizontal rotating tubular bioreactor (HRTB. In both cases, Saccharomyces cerevisiae was used as a production microorganism. During batch ethanol production from the raw sugar beet juice, ethanol yield was 59.89 g/L and production efficiency 78.8 %, and in fed-batch process the yield was 92.78 g/L and efficiency 93.4 %. At the same time, ethanol production in HRTB from the raw sugar beet cossettes with inoculum of 16.7 % V/m (raw sugar beet cossettes resulted in the highest ethanol yield of 54.53 g/L and production efficiency of 79.5 %. The obtained results clearly show that both intermediates of sugar beet processing can be successfully used for ethanol production.

    Full Text Available Necrotizing fasciitis is a life-threatening soft tissue infection that results in rapid local tissue destruction. Type 1 necrotizing fasciitis is characterized by polymicrobial, synergistic infections that are caused by non-Group A streptococci, aerobic and anaerobic organisms. Type 2 necrotizing fasciitis involves Group A Streptococcus (GAS with or without a coexisting staphylococcal infection. Here we provide the first report of necrotizing fasciitis jointly associated with the microbes Group B Streptococcus and Staphylococcus lugdunensis. S. lugdunensis is a commensal human skin bacterium known to cause often painful and prolonged skin and soft tissue infections. To our knowledge, however, this is the first case of Staph. lugdunensis-associated necrotizing fasciitis to be reported in the literature.

    2017-10-01

    This paper is an investigation via two experimental methods, of the textural properties of sugar beet roots during the storage period. In the work, sugar beet roots mechanical properties were evaluated during the post-harvest period - 1, 8, 22, 43, and 71 days after crop. Both experimental methods, i.e. compression test and puncture test, suggest that the failure strength of the sugar beet root increases with the storage time. The parameters obtained using the puncture test, are more sensitive to the storage duration than those obtained by way of the compression test. We also found that such mechanical properties served as a reliable tool for monitoring the progress of sugar beet roots storage. The described methods could also be used to highlight important information on sugar beet evolution during storage.

    Cotton leaf curl disease (CLCuD) has been a problem for cotton production across Pakistan and north-eastern India since the early 1990s. The appearance of the disease has been attributed to the introduction, and near monoculture of highly susceptible cotton varieties. During the intervening period the genetic make-up of the virus(es) causing the disease has changed dramatically. The most prominent of these changes has been in response to the introduction of CLCuD-resistant cotton varieties in the late 1990s, which provided a brief respite from the losses due to the disease. During the 1990s the disease was shown to be caused by multiple begomoviruses and a single, disease-specific betasatellite. Post-resistance breaking the complex encompassed only a single begomovirus, Cotton leaf curl Burewala virus (CLCuBuV), and a recombinant version of the betasatellite. Surprisingly CLCuBuV lacks an intact transcriptional-activator protein (TrAP) gene. The TrAP gene is found in all begomoviruses and encodes a product of ∼134 amino acids that is important in virus-host interactions; being a suppressor of post-transcriptional gene silencing (host defence) and a transcription factor that modulates host gene expression, including microRNA genes. Recent studies have highlighted the differences between CLCuBuV and the earlier viruses that are part of on-going efforts to define the molecular basis for resistance breaking in cotton.

    2014-08-01

    Full Text Available The structure and function of the plant microbiome is driven by plant species and prevailing environmental conditions. Effectuated by breeding efforts, modern crops diverge genetically and phenotypically from their wild relatives but little is known about consequences for the associated microbiota. Therefore, we studied bacterial rhizosphere communities associated with the wild beet B. vulgaris ssp. maritima grown in their natural habitat soil from coastal drift lines (CS and modern sugar beets (Beta vulgaris ssp. vulgaris cultivated in CS and potting soil (PS under greenhouse conditions. Analysis of 16S rRNA gene fingerprints and pyrosequencing-based amplicon libraries revealed plant genotype- and soil-specific microbiomes. Wild beet plants harbor distinct operational taxonomic units (OTUs and a more diverse bacterial community than the domesticated sugar beet plants. Although the rhizospheres of both plant genotypes were dominated by Proteobacteria and Planctomycetes, 47.4% of dominant OTUs were additionally detected in the wild beet rhizosphere. Analysis of the cultivable fraction confirmed these plant genotype-specific differences at functional level. The proportion of isolates displayed in vitro activity against phytopathogens was lower for wild beet (≤45.8% than for sugar beet (≤57.5%. Conversely, active isolates from the wild beet exhibited stronger ability to cope with abiotic stresses. From all samples, active isolates of Stenotrophomonas rhizophila were frequently identified. In addition, soil type-specific impacts on the composition of bacterial communities were found: Acidobacteria, Chloroflexi, and Planctomycetes were only detected in plants cultivated in CS; whereas Bacteroidetes and Proteobacteria dominated in PS. Overall, in comparison to modern sugar beets, wild beets were associated with taxonomically and functionally distinct microbiomes.

    2015-05-01

    Full Text Available World sugar consumption has been recording a steady growth in the past 70 years and, according to all relevant estimates, it will continue to grow also in the next decade, which puts sugar in the category of the most significant foods and commodities in the world. Of the total world sugar production, around 77% is derived from sugar cane and 23% from sugar beet. Brazil has been the world leader in sugar production for a long period of time, producing white sugar from sugar cane only, whereas the leader in the production of sugar derived from sugar beet is the EU-28. When the Republic of Croatia joined the EU, the Croatian sugar industry became part of the single European sugar market, so the break-even point was used in the research to determine the competitiveness level of the Croatian sugar beet production. Based on the expected selling price of sugar beet amounting to EUR 34 per ton of standard quality sugar beet, and using the break-even method, it was determined that the quantity required to cover total costs in sugar beet production in the Republic of Croatia amounts to 55.26 tons per hectare of payable sugar beet, standard quality, i.e. 8.84 tons of polarized sugar per hectare. As the average sugar beet production in the Republic of Croatia, expressed in the equivalent of polarized sugar, amounts to 7.8 tons per hectare, it is obvious that an average Croatian producer of sugar beet, without income from subsidies, operates at a loss.

    Bach, Judith; Jeske, Holger

    2014-04-01

    Long-term surviving sugar beet plants were investigated after beet curly top virus infection to characterize defective (D) viral DNAs as potential symptom attenuators. Twenty or 14 months after inoculation, 20 D-DNAs were cloned and sequenced. In contrast to known D-DNAs, they exhibited a large range of sizes. Deletions were present in most open reading frames except ORF C4, which encodes a pathogenicity factor. Direct repeats and inverted sequences were observed. Interestingly, the bidirectional terminator of transcription was retained in all D-DNAs. A model is presented to explain the deletion sites and sizes with reference to the viral minichromosome structure, and symptom attenuation by D-DNAs is discussed in relation to RNA interference.

    Descending necrotizing mediastinitis (DNM) is a primary complication of cervical or odontogenical infections that can spread to the mediastinum through the anatomic cervical spaces. Between April 1994 and April 2000, 13 patients, mean age 39.23+/-18.47 (median 38, range 16-67) years, with DNM were submitted to surgical treatment. Primary odontogenic abscess occurred in six, peritonsillar abscess in five and post-traumatic cervical abscess in two patients. Diagnosis was confirmed by computed tomography (CT) of the neck and chest. All patients underwent surgical drainage of the cervico-mediastinal regions by a bilateral collar incision associated with right thoracotomy in ten cases. Six patients out of 13 required reoperation. Two patients previously submitted only to cervical drainage required thoracotomy; four patients, which have been submitted to cervico-thoracic drainage, underwent contralateral thoracotomy in two cases and ipsilateral reoperation in two cases. Ten patients evolved well and were discharged without major sequelae; three patients died of multiorgan failure related to septic shock. Mortality rate was 23%. Early diagnosis by CT of the neck and chest suggest a rapid indication of surgical approach to DNM. Ample cervicotomy associated with mediastinal drainage via large thoracotomic incision is essential in managing these critically ill patients and can significantly reduce the mortality rate for this condition, often affecting young people, to acceptable values.

    Full Text Available Levels of sugar and non-sugar (K, Na and amino N depend on environmental conditions and cultural practices applied. At the same time, these traits are an important characteristic of every cultivar. A number of parameters are used to determine the technological maturity of sugar beet, but the main ones are sugar content and sugar utilization percentage, which is affected by the non-sugars. In the present study, the monitoring of root yield and the yield of the above-ground plant parts and the analysis of root quality were done at 15-day intervals starting on July 1 and ending on September 16, 1999. Used in the study were four cultivars and two experimental hybrids of sugar beet. The cultivar Crvenka mz and the experimental hybrid NS Hy 20 proved ultra sugary (on the last lifting date, they had sugar contents 16.28% and 16.54%, respectively. Going from the first to the last lifting date, the K and Na contents of all the cultivars decreased, especially in the cultivar Crvenka mz and the experimental hybrid NS Hy 20. In all of the cultivars. the ammo N content increased until the fourth lifting date (August 16, when it started to decrease. One hundred and fifty days into the growing season, thanks to their high sugar content and low level of non-sugars (especially K and Na, the cultivar Crvenka mz and the hybrid NS Hy 20 had considerably better technological characteristics than the other cultivars. The aforementioned characteristics of Crvenka mz and NS Hy 20 make these two genotypes more suitable for early lifting dates than the other cultivars. .

    To identify potential selective and resistance-breaking mosquitocides against the African malaria vector Anopheles gambiae, we investigated the acetylcholinesterase (AChE) inhibitory and mosquitocidal properties of isoxazol-3-yl dimethylcarbamates (15), and the corresponding 3-oxoisoxazole-2(3H)-dimethylcarboxamide isomers (14). In both series, compounds were found with excellent contact toxicity to wild-type susceptible (G3) strain and multiply resistant (Akron) strain mosquitoes that carry the G119S resistance mutation of AChE. Compounds possessing good to excellent toxicity to Akron strain mosquitoes inhibit the G119S mutant of An. gambiae AChE (AgAChE) with ki values at least 10- to 600-fold higher than that of propoxur, a compound that does not kill Akron mosquitoes at the highest concentration tested. On average, inactivation of WT AgAChE by dimethylcarboxamides 14 was 10-20 fold faster than that of the corresponding isoxazol-3-yl dimethylcarbamates 15. X-ray crystallography of dimethylcarboxamide 14d provided insight into that reactivity, a finding that may explain the inhibitory power of structurally-related inhibitors of hormone-sensitive lipase. Finally, human/An. gambiae AChE inhibition selectivities of these compounds were low, suggesting the need for additional structural modification. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Hybridization between cultivated species and their wild relatives is now widely considered to be common. In the Beta vulgaris complex, the sugar beet seed multiplication areas have been the scene of inadvertent pollination of sugar beet seed bearers by wild ruderal pollen donors, generating a weedy form of beet which infests sugar beet fields in European countries. Up to now, investigations of evolutionary dynamics of genetic diversity within the B. vulgaris complex were addressed using few genetical markers and few accessions. In this study, we tackled this issue using a panel of complementary markers: five nuclear microsatellite loci, four mitochondrial minisatellite loci and one chloroplastic PCR-RFLP marker. We sampled 1,640 individuals that illustrate the actual distribution of inland ruderal beets of South Western France, weed beets and wild sea beets of northern France as well as the diversity of 35 contemporary European diploid cultivars. Nuclear genetic diversity in weed beets appeared to be as high as those of ruderal beets and sea beets, whereas the narrowness of cultivar accessions was confirmed. This genetic bottleneck in cultivars is even more important in the cytoplasmic genome as only one haplotype was found among all sugar beet cultivars. The large majority of weed beet populations also presented this unique cytoplasmic haplotype, as expected owing to their maternal cultivated origin. Nonetheless, various cytoplasmic haplotypes were found within three populations of weed beets, implying wild-to-weed seed flows. Finally, our findings gave new insights into the genetical relationships between the components of the B. vulgaris complex: (1) we found a very strong genetic divergence between wild sea beet and other relatives, which was unexpected given the recent evolutionary history and the full cross-compatibility of all taxa and (2) we definitely confirmed that the classification into cultivated, wild, ruderal and weed forms according to their

    Full Text Available Abstract Background Sugar beet molasses is a viscous by-product of the processing of sugar beets into sugar. The molasses is known to contain sucrose and raffinose, a typical trisaccharide, with a well-established structure. Although sugar beet molasses contains various other oligosaccharides as well, the structures of those oligosaccharides have not been examined in detail. The purpose of this study was isolation and structural confirmation of these other oligosaccharides found in sugar beet molasses. Results Four oligosaccharides were newly isolated from sugar beet molasses using high-performance liquid chromatography (HPLC and carbon-Celite column chromatography. Structural confirmation of the saccharides was provided by methylation analysis, matrix-assisted laser desorption/ionaization time of flight mass spectrometry (MALDI-TOF-MS, and nuclear magnetic resonance (NMR measurements. Conclusion The following oligosaccharides were identified in sugar beet molasses: β-D-galactopyranosyl-(1- > 6-β-D-fructofuranosyl-(2 1-α-D-glucopyranoside (named β-planteose, α-D-galactopyranosyl-(1- > 1-β-D-fructofuranosyl-(2 1-α-D-glucopyranoside (named1-planteose, α-D-glucopyranosyl-(1- > 6-α-D-glucopyranosyl-(1 2-β-D-fructofuranoside (theanderose, and β-D-glucopyranosyl-(1- > 3-α-D-glucopyranosyl-(1 2-β-D-fructofuranoside (laminaribiofructose. 1-planteose and laminaribiofructose were isolated from natural sources for the first time.

    The objective of this paper was to apply terahertz (THz) spectroscopy combined with chemometrics techniques for discrimination of genetically modified (GM) and non-GM sugar beets. In this paper, the THz spectra of 84 sugar beet samples (36 GM sugar beets and 48 non-GM ones) were obtained by using terahertz time-domain spectroscopy (THz-TDS) system in the frequency range from 0.2 to 1.2 THz. Three chemometrics methods, principal component analysis (PCA), discriminant analysis (DA) and discriminant partial least squares (DPLS), were employed to classify sugar beet samples into two groups: genetically modified organisms (GMOs) and non-GMOs. The DPLS method yielded the best classification result, and the percentages of successful classification for GM and non-GM sugar beets were both 100%. Results of the present study demonstrate the usefulness of THz spectroscopy together with chemometrics methods as a powerful tool to distinguish GM and non-GM sugar beets.

    2016-01-01

    Full Text Available Cervical necrotizing fasciitis is an unusual infection characterized by necrosis of the subcutaneous tissue and fascial layers. Risk factors for the development of necrotizing fasciitis include diabetes mellitus, chronic renal disease, peripheral vascular disease, malnutrition, advanced age, obesity, alcohol abuse, intravenous drug use, surgery, and ischemic ulcers. This report presents a case of necrotizing fasciitis in the cervical area caused by dental extraction in a 73-year-old woman. Cervical necrotizing fasciitis in geriatric patient is rare, and even when establishing the diagnosis and having it timely treated, the patient can suffer irreversible damage or even death. Clinical manifestations in the head and neck usually have an acute onset characterized by severe pain, swelling, redness, erythema, presence of necrotic tissue, and in severe cases obstruction of the upper airways. Therefore, the presentation of this clinical case can serve as guidance to dentists as a precaution to maintain an aseptic chain and be aware of the clinical condition of older patients and the systemic conditions that may increase the risk of infections.

    Necrotizing fasciitis is an infection of any layer of tissue compartment; it can be in the dermis, subcutaneous tissue, superficial fascia, deep fascia, or even muscle. Usually, necrotizing fasciitis is associated with necrotizing process caused by the single bacterial organism. The most common pathogen is group A Streptococcus. Delayed in the diagnosis and surgical treatment of necrotizing fasciitis will lead to increased tissue loss and high mortality risk. Here we report a case of necrotizing fasciitis which has a great outcome since the surgical exploration of tissue and debridement was done as soon as the patient is suspected of necrotizing fasciitis.

    Full Text Available Necrotizing fasciitis is a severe, rare, potentially lethal, soft tissue infection that tends to develop in scrotum, perineum, abdominal wall or the extremities. It is a medical emergency that threatens both patient’s limb and life. Necrotizing fasciitis has the potential to become quite severe - in such cases a radical debridement amounting to amputation of the limb may be required to save the patient’s life. Early diagnosis requires a high index of suspicion. We describe a case of a 49-year-old obese woman who developed necrotizing fasciitis in her left lower limb for which she underwent multiple radical surgical debridement, followed by skin grafting for reconstruction of the limb defects. Our main focus was to salvage the limb with the help of antibiotics and multiple debridements. This report emphasizes the need to have a relook at the use of Parenteral Crystalline Penicillin and diligent management of wounds resulting from repeated debridements.

    To evaluate the effect of high dose quinolones therapy in patients with necrotizing fasciitis. Subjects and Methods: Twenty consecutive patients, diagnosed with necrotizing fasciitis, were treated with intravenous quinolones, (400 mg 8 hourly). The response was evaluated in terms of subsidence of fever and C-reactive proteins levels. Results: Majority of the patients was male (60%). Lower limb involvement was most commonly involved (70%). The most common initiating cause was injection abscess (45%). Majority of the cultures showed polymicrobial infection (90%). The most common isolate was streptococcus pyogenes (65%). Majority of the patients showed excellent response with intravenous quinolones (Ciprofloxacin) in high doses in 24-48 hours. Only two patients (10%) failed to respond to therapy due to severe infection and delay in seeking treatment. Conclusion: intravenous quinolones (Ciprofloxacin) in high doses are effective in controlling necrotizing soft tissue infections. (author)

    Necrotizing fasciitis (NF) is a rare infection (0,2 to 0,4/100,000 adults) of the dermis and hypodermis extending along muscular fascia1. The absence of pathognomonic symptoms makes its diagnosis difficult. Rapidly progressive, it is a life-threatening emergency whose prognosis is letal in 30 % of cases. Treatment of necrotizing fasciitis is mixed and involves aggressive surgical debridement and medical treatment with antibiotics and supportive agents. This article is presenting the case of a young woman who developed abdominal necrotizing fasciitis following a caesarean section. In forty-eight hours, the patient developed septic shock with an extensive and rapid destruction of her abdominal wall. After hysterectomy and multiple surgical debridements, evolution was favorable. After one month, a reconstruction of the abdominal wall could be performed.

    Full Text Available Summary. Sugar beet is one of the strategic crops for food safety of Russia. The lack of specialized warehouse for harvest does not provide storage of roots for a long time. In the case of a thaw roots that have been defrosted unsuitable for processing. Beet and products of its processing is a good object for the development of microorganisms. Permanent microflora of sugar production are: Bacillus subtilis, Clostridium perfringes, Leuconostoc dextranicum, Torula alba, Pseudomonas fluorescens, Sarcina lutea and other kinds of microorganisms, leading to a problem processing of beet root and reduced quality of sugar. The most dangerous is the slimy bacteriosis is a bacterial disease beet caused by heterofermentative cocci of Leuconostoc (Leuconostoc mesenteroides, L. dextranicum. Product of the vital activity of microorganisms is dextran, which is synthesized from sucrose as a result of dextrany or mucous fermentation and leads to significant technological problems in processing of infected beet. Improving the efficiency of sugar production is connected with decrease in loss of quality of raw material preparation, storing and processing of sugar beet. At sugar plants use a variety of drugs that suppress the growth of pathogenic microflora, but there comes a rapid adaptation of microorganisms, therefore there is a need to implement new products to prevent damage to roots and improve the quality of produced sugar. To resolve this problem experimentally selected bactericidal drug, defined its rational concentration and conditions for the use in sugar beet production. The use of antibacterial drug in the process of extraction allows to increase the purity of diffusion juice 1.3 %, reduce the protein content in it (12.5 %; with the purity of the pure juice increases by 1.1 %, its color index is reduced by 44.7 %.

    Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030

    Smit, A.B.; Helming, J.F.M.

    2012-01-01

    Abolishment of EU sugar quotas will lead to lower sugar and sugar beet prices in the EU, leading to lower margins for farms. At the same time, expansion of sugar beet growing and processing in a quota-free situation can decrease fixed cost per ha of sugar beet and per kg of sugar, making both sugar beet growing and processing more efficient. Besides, lower sugar price levels will make Europe a more attractive continent for investments by sugar-based industries.

    To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gas shadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer in four cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focal low density lesion suggestive of focal abscess was not visualized. Plain radiography is useful for early diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

    2008-12-01

    Full Text Available Introduction: Necrotizing fasciitis is a bacterial infection characterized by extensive necrosis of tissues, and may include skin and muscles. It's more frequent in adults than in children and generally involves the trunk and extremities. Head and neck area is less commonly affected. The most frequently isolated pathogens are the Streptococcus pyogenes (group A and Staphylococcus aureus. The anatomopathological exam is the best diagnostic method, which early identifies the disease. The clinical support, surgical debridement, and the intravenous antibiotic therapy, are fundamental for the treatment. Objective: To report a case of an infant who suffered from Cervical Necrotizing Fasciitis. Case Report: Infant, male sex, white, 2 months old, previously healthy, with Necrotizing Fasciitis involving the frontal and right lateral cervical regions. After adequate treatment the patient obtained excellent recovery without presenting important aesthetic or functional alterations. Conclusion: The Cervical Necrotizing Fasciitis is uncommon in children. The early surgical debridement is necessary to control the infection, even if it may result in great and deep injuries. The wide spectrum antibiotic therapy and hemodynamic support are also basic for the therapeutic success.

  7. Effect of sugar beet root aphid, Pemphigus fuscicornis (Homoptera: Pemphigidae), on sugar beet yield and quality in Iran.

    Zarrabi, M

    2007-10-01

    Pemphigus fuscicornis (Koch) is a pest of sugar beet root in warm and dry regions of Iran. This belongs to the Middle East and south east of Asia fauna. Nymphs establish colonies in root sutures and feed heavily which cause wilting and yellowing in beet near harvest. This study was conducted to determine infestation indices, damage occurrence and the necessity for control measures of this pest. Nymph colonies were monitored in different experimental fields that were planted with commonly used monogerm variety Afshari and then five infested places were selected. Damaged root specimens were sampled from five foci and ranked for infestation, yield and sugar concentration. Results indicated that there were no significant differences in weight, sugar concentration and impurities between indices 1, 2, 3 and none infested beets. Only the sugar concentration of indices 4 showed significant differences with zero infested beets. In the other hand, no specimens were found with the highest population density index (indices 5). Therefore, the sugar beet root aphid populations did not reach to the level of economic damage in these experimental fields. Thus, the control measures such as chemical application and use of resistant varieties may be used when the colonies density increases to the indices four and five throughout the foci in such fields.

    Cervical necrotizing fasciitis is a rare but very severe infection that affects the soft-tissues of the cephalic extremity. Cervical necrotizing fasciitis most frequently occurs secondarily to inflammatory odontogenic disorders and represents the most severe infection of maxillofacial spaces, with a high lethal potential. In this study, we selected 55 patients with confirmed cervical necrotizing fasciitis of odontogenic origin, treated in the Clinic of Oral and Maxillofacial Surgery in Cluj-Napoca during January 1996-December 2012. In the majority of cases, the disease evolved without the presence of associated systemic disorders (60% [45.49-72.69]), the rest of the patients having 1-4 types of systemic disorders; type 2 diabetes mellitus was the most frequent type of underlying systemic disorder. From the appearance of the first symptoms until the presentation for treatment, a time interval of 2-30 days elapsed. During this time period, 78.18% (95% confidence interval [CI] [65.49-89.06]) of the patients received antibiotic treatment, but without results. Mandibular molars were the most frequent starting point of the disease, and the submandibular space was the first affected by the disease, 47.27% (95% CI [32.76-61.79]). Bacteriological exams showed that facultatively aerobic/anaerobic G + bacteria were the most frequently identified (72.22% [58.21-83.60]). The odontogenic lesions of the lower molars, complicated by submandibular space infections, are the most frequent starting point of odontogenic cervicofacial necrotizing fasciitis. Delayed surgical treatment and strict antibiotic therapy play an important role in favoring the development of odontogenic necrotizing fasciitis.

    Full Text Available This paper presents a synthesis of the results obtained during a long- -term investigations conducted on the distribution of aphidophagous coccinellid species and their quantitative and qualitative structure in sugar beet fields in Vojvodina. Composition of coccinellid communities and the annual changes in abundance of species are influenced by many variable environmental factors, but also by the prey availability during the season. Chemical treatments against flea beetles in May or/and against noctuid larvae in late July and the type of the adjacent crops may also affect the quantitative composition of adults coccinellid on sugar beet fields. During the season adults coccinellid are more abundant than larvae. The qualitative structure of coccinellid communities in sugar beet fields is not different than those from other field crops. These communities consist mainly of Coccinella septempunctata L.; Semiadalia undecimnotata Schn.; Propylaea quatuordecimpunctata L.; Hippodamia (Adonia variegata Goeze and Hippodamia tredecimpunctata L. Other species are present in a small fractions.

    Research concerning the sensory properties of beet and cane sugars is lacking in the scientific literature. Therefore, the objectives of this research were to determine whether a sensory difference was perceivable between beet and cane sugar sources in regard to their (1) aroma-only, (2) aroma and taste without nose clips, and (3) taste-only with nose clips, and to characterize the difference between the sugar sources using descriptive analysis. One hundred panelists evaluated sugar samples using a tetrad test. A significant difference (P cane sugar sources when evaluated by aroma-only and taste and aroma without nose clips. However, there was no difference when tasted with nose clips. To characterize the observed differences, ten trained panelists identified and quantified key sensory attributes of beet and cane sugars using descriptive analysis. Analysis of variance indicated significant differences (P sugar samples for 8 of the 10 attributes including: off-dairy, oxidized, earthy, and barnyard aroma, fruity and burnt sugar aroma-by-mouth, sweet aftertaste, and burnt sugar aftertaste. The sensory profile of beet sugar was characterized by off-dairy, oxidized, earthy, and barnyard aromas and by a burnt sugar aroma-by-mouth and aftertaste, whereas cane sugar was characterized by a fruity aroma-by-mouth and sweet aftertaste. This study shows that beet and cane sugar sources can be differentiated by their aroma and provides a sensory profile characterizing the differences. As sugar is used extensively as a food ingredient, sensory differences between beet and cane sugar sources once incorporated into different product matrices should be studied as a next step. © 2014 Institute of Food Technologists®

  11. TO SUBSTANTIATION OF COMBINE WHEELED CHASSIS FOR BEET HARVESTING EQUIPMENT

    2016-01-01

    Full Text Available The paper considers a current scientific and technical problem pertaining to creation of multi-bridge wheeled chassis for highly efficient modular sugar beet harvesters of large cargo capacity and, in particular, to selection of main parameters of chassis and wheeled drive. Such machines are designed for operation under complicated soil and climatic conditions during sugar beet harvesting. Methodological rules and regulations have been developed for solution of problems pertaining to scientifically sunstantiated selection of a manufactured or developed wheeled chassis model, building-block parameters of a working device and a chassis, rational control algorithm of the unit running system while using a specified (domestic or foreign semi-mounted equipment for beet harvesting. While solving the problem theoretical provisions for wheeled vehicles regarding specific features of a wheeled chassis for modular sugar beet harvesters with extensive mechanical or hydrostatic wheel drive of a multi-bridge propulsion system have been developed in the paper. Calculated and theoretical expressions for determination of main parameters for a wheeled chassis have been obtained and they include physical quantities of operational conditions that explicitly determine its working process. Such approach has made it possible to realize the obtained expressions as a software application which is suitable for analysis of main parameters in respect of the investigated harvester chassis and rational parameters of a branch wheel drive and also for a complete set of tires in the case when a sugar beet harvester is designed on the basis of wheeled chassis according to the selected scheme. Investigations have theoretical significance and represent practical interest for development spesialists of new modular multi-bridge sugar beet harvesters.

    Two patients with rapidly progressive necrotizing fasciitis of a lower extremity due to Staphylococcus aureus as a single pathogen are described. In both patients the portal of entry was attributed to needle puncture (intra-articular injection and intravenous catheter, respectively), followed by bacteremia. Necrotizing fasciitis occurred in a site remote from the needle puncture, suggesting metastatic infection. One patient developed toxic shock syndrome and the other a sunburn-like rash and erythematous mucosae with strawberry tongue. One patient died, and the other required above-knee amputation due to secondary infectious complications. Staphylococcus aureus may mimic the presentation of invasive group A streptococcal infections. A history of needle puncture should alert the physician to the possibility of Staphylococcus aureus infection.

    Alcohol production rate decreases as the concentration of bacterial contaminants increases. In complex medium, such as beet molasses, an alternative mechanism can be used by homofermentative lactic bacteria (Lactobacillus casei). Lactic acid and associated products, especially acetic acid, are liberated into the medium. The inhibition induced by these metabolites was reinforced by the presence of viable lactobacilli.

    Three sugar beet herbicides, ethofumesate, phenmedipham and metamitron, are currently used on conventional sugar beet cultivation, while new varieties of herbicide resistant (HR) sugar beet, tolerant of glyphosate or glufosinate-ammonium, are under field testing in Finland. Little knowledge has so far been available on the adsorption of these herbicides to Finnish soils. The adsorption of these five herbicides was studied using the batch equilibrium method in 21 soil samples collected from different depths. Soil properties like organic carbon content, texture, pH and partly the phosphorus and oxide content of the soils were tested against the adsorption coefficients of the herbicides. In general, the herbicides studied could be arranged according to their adsorption coefficients as follows: glyphosate>phenmedipham>ethofumesate approximately glufosinate-ammonium>metamitron, metamitron meaning the highest risk of leaching. None of the measured soil parameters could alone explain the adsorption mechanism of these five herbicides. The results can be used in model assessments of risk for leaching to ground water resulting from weed control of sugar beet in Finland.

    2017-11-01

    Some strains of Staphylococcus aureus produce a toxin known as Panton-Valentine leukocidin. These strains notably cause a necrotizing pneumonia which is associated with a high mortality. A 70-year-old woman presented with sub-acute onset dyspnea, low-grade fever, and hemoptysis after a trip to Dubai and New Zealand. Computed tomography showed bilateral necrotizing pneumonia, suggesting the diagnosis of pneumonia caused by S. aureus producing Panton-Valentine toxin. It was confirmed by microbiological investigation. The rapid initiation of adequate antimicrobial therapy including an effective antitoxin was essential for successful treatment, without the need for ventilatory support. Necrotizing pneumonia caused by S. aureus producing Panton-Valentine leukocidin usually occurs in young subjects without comorbidities. Typical symptoms are a combination of hypoxemia, high fever, hemoptysis, leukopenia, and a rapidly worsening condition. Panton-Valentine leukocidin should not be discarded if not all the symptoms are typical. Antibiotic therapy including an antitoxin drug such as linezolid or clindamycin should be initiated promptly.

    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

    Full Text Available Paroxysmal nocturnal hemoglobinuria (PNH is a rare, progressive, and life-threatening hematopoietic stem cell disorder characterized by complement-mediated intravascular hemolysis and a prothrombotic state. Patients with PNH might have slightly increased risk of infections due to complement-associated defects subsequent to CD59 deficiency. Here, we report a rare case of a 65-year-old male patient with necrotic ulcers on both legs, where the recognition of pancytopenia and microthrombi led to the diagnosis of PNH based on FLAER (FLuorescent AERolysin flow cytometric analysis. He was subsequently started on eculizumab therapy, with starting and maintenance doses set as per drug labelling. Progression of the patient’s leg ulcers during follow-up, with fulminant tissue destruction, purulent discharge, and necrotic patches, led to a later diagnosis of necrotizing fasciitis due to Pseudomonas aeruginosa and Klebsiella pneumonia infection. Courses of broad-spectrum antibiotics, surgical debridement, and superficial skin grafting were applied with successful effect during ongoing eculizumab therapy. This case highlights the point that it is important to maintain treatment of underlying disorders such as PNH in the presence of life-threatening infections like NF.

E-mail: suellenramosvet@hotmail.com The sialometaplasia is a rare disease of unknown cause in dogs and cats, which usually affects the submandibular salivary gland, caused by trauma, physical-chemical or biological attack in blood vessels that can produce ischemic changes, causing necrosis, scaly inflammation and metaplasia of glandular epithelium and ducts. Animals affected by sialometaplasia necrotizing show pain, an increase in salivary glands and regional lymphadenopathy. Ultrasonography associated with biopsy of the affected tissue are effective in diagnosing the disease. The treatment is surgical and symptomatic. In this study, we tried to report the case of a half-breed dog, 6 years old, who presented the symptoms and histopathological diagnosis of necrotizing sialometaplasia.

    Brown recluse (Loxosceles spp.) spiders are arachnid species known to cause necrotic arachnidism. The envenomation, described as loxoscelism, is associated with localized pain, erythema, and edema followed by the development of necrosis. However, the specific pathophysiological mechanisms by which Loxosceles venom exerts these noxious symptoms are multifactorial and not fully understood. The causative factor for production of necrotic lesions is generally considered to be the enzyme sphingomyelinase D (SMD), which cleaves sphingomyelin to form choline and ceramide 1-phosphate. Four active forms of SMD with molecular weight of 32 000 are found in L recluse. Sphingomyelinases of comparable size are also described in the venoms of Loxosceles intermedia, gaucho and laeta. Here we describe the case of a young male adult who suffered a spider bite on his left forearm which evolved into a necrotic lesion, and after a few days the injury healed completely. One week later the patient developed two similar lesions on his left leg. The diagnosis was established by clinical data and by biopsy findings. The patient did not developed systemic complications.

  12. CO-PROCESSING BEET AND CANE RAW SUGAR

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Many sugar factories of the Russian Federation sugar and white sugar is produced not only from sugar beet, but also from raw sugar. To do this, the technological scheme of the plants provide mostly separate processing beet and raw sugar. This paper proposes a joint processing. With the aim of improving the quality of syrup, improving the filtration properties of the juice II saturation with joint processing beet and raw sugar was proposed clarification raw sugar to conduct the filtered juice I saturation with the addition of bleach in the amount of 0.05-0.10 % by weight of raw sugar and fine clay powder in the amount of 0.3-0.5 % by weight of raw sugar. Introduction chlorine is in the process of clarification raw sugar partly to carry out the depolymerization of highmolecular compounds, including polysaccharide dextran, and to adsorb the resulting fragments of high molecular compounds and pigments on fine particles of clay powder. Similar results were obtained when changing the costs of expanded clay powder. At a flow rate less than 0.3 %, there is a lack of adsorption of the surface to remove the degradation products of high -molecular compounds, which degrades the quality characteristics of the mixture of woodworking and furniture production of raw sugar and juice I carbon ation, and at a rate clay powder more than 0.5 % is irrational, since the cleaning effect is increased slightly. Suggested ways of coprocessing beet and raw sugar allow without significant cost effective processing of raw sugar factories. When beet low techn ological quality of these methods will increase the cleanliness of the production of sugar solutions and improve conditions for obtaining sugar of standard quality with the normative content of sucrose in molasses.

    In sugar beet (Beta vulgaris altissima), bolting tolerance is an essential agronomic trait reflecting the bolting response of genotypes after vernalization. Genes involved in induction of sugar beet bolting have now been identified, and evidence suggests that epigenetic factors are involved in their control. Indeed, the time course and amplitude of DNA methylation variations in the shoot apical meristem have been shown to be critical in inducing sugar beet bolting, and a few functional targets of DNA methylation during vernalization have been identified. However, molecular mechanisms controlling bolting tolerance levels among genotypes are still poorly understood. Here, gene expression and DNA methylation profiles were compared in shoot apical meristems of three bolting-resistant and three bolting-sensitive genotypes after vernalization. Using Cot fractionation followed by 454 sequencing of the isolated low-copy DNA, 6231 contigs were obtained that were used along with public sugar beet DNA sequences to design custom Agilent microarrays for expression (56k) and methylation (244k) analyses. A total of 169 differentially expressed genes and 111 differentially methylated regions were identified between resistant and sensitive vernalized genotypes. Fourteen sequences were both differentially expressed and differentially methylated, with a negative correlation between their methylation and expression levels. Genes involved in cold perception, phytohormone signalling, and flowering induction were over-represented and collectively represent an integrative gene network from environmental perception to bolting induction. Altogether, the data suggest that the genotype-dependent control of DNA methylation and expression of an integrative gene network participate in bolting tolerance in sugar beet, opening up perspectives for crop improvement. © The Author 2015.

    Fodder and sugar beet silage as mono-substrate has been studied for their fermentation behaviour in semi-continuous biogas tests according to VDI guideline 4630. Especially the methane formation potential and the maximum loading rate of different beet varieties are in the focus of investigations. It has been shown that sugar beet silage can be used with a lower loading rate in the biogas digester as fodder beet silage. Here, the methane yields of sugar beet silages tend to be higher than the methane yields of the investigated fodder beet silage. The methane yields of the individual beet silage are not depending on the dry matter content of the investigated beets. In the co-fermentation of corn silage and beet silage, the proportion of beet silage at the dry matter content of the feed is crucial for a stable fermentation process. Furthermore sugar beet silage has economic advantages compared to silage from fodder beets due to a higher methane production potential. The deployment costs of sugar beet silage are significantly depending on the variety and choice of silage method and lie at the level of corn silage. In case of a digestion of the beet variety Mosaik as silage the deployment might be underneath the deployment costs of corn silage. (orig.)

    The structure and function of the plant microbiome is driven by plant species and prevailing environmental conditions. Effectuated by breeding efforts, modern crops diverge genetically and phenotypically from their wild relatives but little is known about consequences for the associated microbiota. Therefore, we studied bacterial rhizosphere communities associated with the wild beet B. vulgaris ssp. maritima grown in their natural habitat soil from coastal drift lines (CS) and modern sugar beets (Beta vulgaris ssp. vulgaris) cultivated in CS and potting soil (PS) under greenhouse conditions. Analysis of 16S rRNA gene fingerprints and pyrosequencing-based amplicon libraries revealed plant genotype- and soil-specific microbiomes. Wild beet plants harbor distinct operational taxonomic units (OTUs) and a more diverse bacterial community than the domesticated sugar beet plants. Although the rhizospheres of both plant genotypes were dominated by Proteobacteria and Planctomycetes, 37.5% of dominant OTUs were additionally detected in the wild beet rhizosphere. Analysis of the cultivable fraction confirmed these plant genotype-specific differences at functional level. The proportion of isolates displayed in vitro activity against phytopathogens was lower for wild beet (≤45.8%) than for sugar beet (≤57.5%). Conversely, active isolates from the wild beet exhibited stronger ability to cope with abiotic stresses. From all samples, active isolates of Stenotrophomonas rhizophila were frequently identified. In addition, soil type-specific impacts on the composition of bacterial communities were found: Acidobacteria, Chloroflexi, and Planctomycetes were only detected in plants cultivated in CS; whereas Bacteroidetes and Proteobacteria dominated in PS. Overall, in comparison to modern sugar beets, wild beets were associated with taxonomically and functionally distinct microbiomes. PMID:25206350

    Necrotizing fasciitis (NF) is uncommon and difficult to diagnose, and it cause progressive morbidity until the infectious process is diagnosed and treated medically and surgically. The literature addressed NF contains confusing information, inaccurate bacteriologic data, and antiquated antibiotic therapy. A delay in diagnosis is associated with a grave prognosis and increased mortality. The main goal of the clinician must be to establish the diagnosis and initially treat the patient within the standard of care. This review is planned as a guide for the clinician in making an early diagnosis of NF and initiating effective medical and surgical therapy.

    Cervico-facial necrotizing fasciitis is a potential complication of odontogenic infection that can lead to mediastinitis and septic shock. A delay or inappropriate treatment of simple infections and immunocompromise increase the risk of developing the disease and in turn increase the morbidity and mortality of the disease. We present two cases one of which we believe developed due to delayed treatment and the other due to immunocompromise. Both cases were successfully treated with surgical debridement and broad spectrum antibiotics. There is need to rethink certain clinical judgments such as treatment during pregnancy and the usefulness of an informative medical history from patients. (author)

    Molasses is an important by-product of sugar beet or sugar cane refining industry and it was one of the first sweeteners used in human nutrition. Sugar cane molasses has unique characteristics that can make it suitable for application in food industry, especially in confectionery and bakery products. On the other hand, sugar beet molasses has not had greater application in the human diet, primarily because of its strong smell and taste of the beet, which makes it unattractive for consumption....

    Sugar beet is spring-sown for sugar production in most sugar beet-growing countries. It is grown as a vegetative crop and it accumulates yield (sugar) from very early in its growth cycle. As long as the sugar beet plants do not flower, the sugar accumulation period is indefinite and yield continues to increase. This paper reviews the success of the sugar beet crop in capturing and using solar radiation, water and mineral nitrogen resources. The prospects for improved resource capture and therefore increased sugar yield are also considered, particularly the potential to increase solar radiation interception in the future by sowing the crop in the autumn.

    2013-01-01

    Based on the observation that coagulation necrosis occurs in the majority of neonatal necrotizing enterocolitis (NEC) patients, it is clear that intestinal ischemia is a contributing factor to the pathogenesis of NEC. However, the published studies regarding the role of intestinal ischemia in NEC are controversial. The aim of this paper is to review the current studies regarding intestinal microcirculatory dysfunction and NEC, and try to elucidate the exact role of intestinal microcirculatory dysfunction in NEC. The studies cited in this review were mainly obtained from articles listed in Medline and PubMed. The search terms used were "intestinal microcirculatory dysfunction" and "neonatal necrotizing enterocolitis". Mainly original milestone articles and critical reviews written by major pioneer investigators in the field were selected. Immature regulatory control of mesentery circulation makes the neonatal intestinal microvasculature vulnerable. When neonates are subjected to stress, endothelial cell dysfunction occurs and results in vasoconstriction of arterioles, inflammatory cell infiltration and activation in venules, and endothelial barrier disruption in capillaries. The compromised vasculature increases circulation resistance and therefore decreases intestinal perfusion, and may eventually progress to intestinal necrosis. Intestinal ischemia plays an important role through the whole course of NEC. New therapeutic agents targeting intestinal ischemia, like HB-EGF, are promising therapeutic agents for the treatment of NEC.

    2013-12-01

    Full Text Available Acute pancreatitis (AP is a potential life-threatening disease, which originates from inflammatory involvement of the pancreas and surrounding tissues. Serious complications eventuate and treatment is difficult. AP is classified in both interstitial edematous pancreatitis, which occurs in 70-80% of patients, and necrotizing pancreatitis, which occurs in 20-30% of patients. Diagnosis is based on the presence of two of the following criteria: abdominal pain, increased serum determination of amylase and/or lipase more than three times the reference value, and characteristic tomographic findings. Among the latter, there is the pancreatic and surrounding tissue damage as well as that related to distant organ involvement. This case report shows the fatal case of a male patient with a history of heavy alcoholic abuse admitted with the diagnosis of necrotizing pancreatitis. The authors call attention to the unusual tomographic findings; namely, a huge duodenal hematoma and a large hemoperitoneum, ischemic involvement of the spleen and kidneys, as well as pancreatic and peripancreatic necrosis.

    Full Text Available Background and aims. Descending necrotizing mediastinitis (DNM is a rare and life-threatening infection. Management of this condition is very difficult and before 1990s, DNM had a mortality rate of 40% despite the use of antibiotics. One of the etiologies of this condition is rapid downward spread of oropharyngeal infection along the cervical fascia planes into the mediastinum. Materials and methods. Patients with DNM from odontogenic, peritonsillar and retropharyngeal origins, who underwent surgical treatment from 1990 to 2007, were reviewed. Data extracted from medical records of the patients included age, gender, origin of the infection, surgical approaches, and the cause of mortality. Descriptive data were expressed as a Mean ± SE. Results. Thirteen patients aged 15 to 56 (mean, 34.5 years old; 8 males and 5 females were studied. The origins of infection included odontogenic abscess in 10 cases and peritonsillar and retropharyngeal abscess in 3 patients. The mean duration from onset of symptoms to the surgery was 12.18 ± 0.98 days (range 3 to 24 days and the mean duration from initial surgery to discharges was 28.51 ± 3.25 days (range 5 to 92 days. Post-operative mortality was seen in three patients. Conclusion. Descending necrotizing mediastinitis can arise from odontogenic abscesses and must be detected as early as possible, as it is a life-threatening infection.

    2017-07-01

    Increase of saline lands in most regions of the world and Iran, limit of production increase based on land enhancement and also threat of saline water and soils for crop production make related researches and production of salt tolerant variety to be more serious. There have been many researches about salt stress in Sugar Beet Seed Institute of Iran (SBSI) during several years. Accordingly, the new screening methods for stress tolerance to be continued based on these researches. Previous researches in SBSI were reviewed and results concluded to this study which is presented in this article in three categories including: Agronomy, Breeding and Biotechnology. In agronomy researches, suitable planting medium, EC, growth stage and traits for salinity tolerance screening were determined and agronomic technique such as planting date, planting method and suitable nutrition for sugar beet under salt stress were introduced. Sand was salinizied by saline treatments two times more than Perlit so large sized Perlit is suitable medium for saline studies. Sugar beet genotypes screening for salt tolerance and should be conducted at EC=20 in laboratory and EC= 16 dS/M in greenhouse. Although sugar beet seed germination has been known as more susceptible stage to salinity, it seems establishment is more susceptible than germination in which salinity will cause 70-80% decrease in plant establishment. Measurements of leaves Na, K and total carbohydrate at establishment stage would be useful for faster screening of genotypes, based on high and significant correlation of these traits at establishment with yield at harvest time. In breeding section, SBSI genotypes with drought tolerance background would be useful for salinity stress studies and finally there is a need for more research in the field of biotechnology in Iran.

    The detailed analysis of hydrolysis of beet pulp by anaerobic mixed cultures showed that a wide range of extracellular enzymes can be found. Notably pectinases, pectin lyases, arabanases, galactanases and cellulases are secreted. Under appropriate conditions high levels of enzyme concentrations can be observed. Intermediate accumulation of oligosaccharides makes probable well known mechanisms of enzyme induction and repression. A two stage system with membrane filtration and ultrafiltration allowed for convenient production of concentrated stable enzyme solutions.

  17. The capacity of sugar beet farms’ machinery and equipment

    Directory of Open Access Journals (Sweden)

    Małgorzata BZOWSKA – BAKALARZ

    2012-12-01

    Full Text Available The survey investigates into equipment of sugar beet farms of the Lublin region, Poland, with machinery – with reference to plantation size and yields. To assess the production potential of the farms, the authors determined the age structure of the machinery owned by the farmers and established the scale of investment in new equipment. The machinery most important for sugar beet production are pre-sowing and post-harvest tillage units, sprayers, seed drills, combine harvesters and self-unloading trailers. In most cases, the surveyed farmers own most of these machines, but they are often obsolete: 37% of them is in operation for more than 15 years. As for the machines dedicated solely to sugar beet growing (harvesters and seeders, their age structure is most unfavourable – 70% of them have been used for over 15 years. A trend towards increasing plantation sizes provides incentives for introducing innovation to cultivation methods. However, the scale of investment in new machinery is small, especially in the case of small and medium-sized farms that dominate in the region. The authors surveyed also the scale of using professional services in the field of tillage processes to determine changes in farming practices.

  18. The addition of sugar beet to ethanol pathway in GHGenius

    International Nuclear Information System (INIS)

    2007-01-01

    Developed by Natural Resources Canada, the GHGenius model is used to estimate the life cycle emissions of primary greenhouse gases (GHGs) as well as the criteria pollutants from combustion sources. The model can be used to analyze the emissions from conventional and alternatively fuelled combustion engines and fuel cell powered trucks and vehicles, as well as light duty powered electric vehicles. Over 140 vehicle and fuel combinations can be used. This paper examined the effects of adding energy used to produce materials consumed in the production of alternative fuels in GHGenius energy balance calculations, as well as vehicle emission calculations on a carbon dioxide (CO 2 ) eq/GJ of fuel consumed basis. This paper also examined the addition of sugar beet ethanol pathways to GHGenius. Energy balances were obtained and a number of process improvements to sugar beet ethanol processing were examined as sensitivity cases. GHGenius was used to calculate the energy consumption of each stage in the production cycle. Estimates included the energy required to produce the chemicals used in the ethanol processing procedure. Results were then compared with results obtained from gasoline, corn and wheat ethanols. Results of the study showed that energy balances were lower than corn or wheat ethanol. Feedstock transmission and processing requirements were also higher due to the higher moisture content of the feedstock. The results of several European studies considering the use of sugar beet ethanol were also included. 17 tabs., 9 figs

    Salt tolerance of higher plants is determined by a complex set of traits, the timing and rate of evolution of which are largely unknown. We compared the salt tolerance of cultivars of sugar beet and their ancestor, sea beet, in hydroponic studies and evaluated whether traditional domestication and more recent breeding have changed salt tolerance of the cultivars relative to their ancestor. Our comparison of salt tolerance of crop cultivars is based on values of the relative growth rate (RGR) of the entire plant at various salinity levels. We found considerable salt tolerance of the sea beet and slightly, but significantly, reduced salt tolerance of the sugar beet cultivars. This indicates that traditional domestication by selection for morphological traits such as leaf size, beet shape and size, enhanced productivity, sugar content and palatability slightly affected salt tolerance of sugar beet cultivars. Salt tolerance among four sugar beet cultivars, three of which have been claimed to be salt tolerant, did not differ. We analysed the components of RGR to understand the mechanism of salt tolerance at the whole-plant level. The growth rate reduction at higher salinity was linked with reduced leaf area at the whole-plant level (leaf area ratio) and at the individual leaf level (specific leaf area). The leaf weight fraction was not affected by increased salinity. On the other hand, succulence and leaf thickness and the net assimilation per unit of leaf area (unit leaf rate) increased in response to salt treatment, thus partially counteracting reduced capture of light by lower leaf area. This compensatory mechanism may form part of the salt tolerance mechanism of sea beet and the four studied sugar beet cultivars. Together, our results indicate that domestication of the halophytic ancestor sea beet slightly reduced salt tolerance and that breeding for improved salt tolerance of sugar beet cultivars has not been effective.

    2003-04-01

    ABSTRACT A polymerase chain reaction (PCR)-based method for the detection of the curtovirus Beet mild curly top virus (BMCTV, previously named the Worland strain of Beet curly top virus) was developed and used to investigate the BMCTV-beet leafhopper interaction. Using PCR and a BMCTV-specific primer pair, an approximately 1.1-kb BMCTV DNA fragment was amplified from adult leafhoppers and from the organs involved in circulative transmission: the digestive tract, hemolymph, and salivary glands. The temporal distribution of BMCTV in the leafhopper was determined using insects given acquisition access periods (AAPs) ranging from 1 to 48 h on BMCTV-infected shepherd's purse plants. BMCTV was detected in the digestive tract after all AAPs, in the hemolymph after AAPs of 3 h or greater, and in the salivary glands after AAPs of 4 h or greater. The amount of virus detected in the hemolymph and salivary glands increased with AAP length. The virus persisted for up to 30 days in leafhoppers (given a 3-day AAP on BMCTV-infected plants) maintained on corn plants, a nonhost for BMCTV, but transovarial transmission was not detected. These results are consistent with a persistent but nonpropagative mode of circulative transmission.

    To analyze CT and follow-up chest radiographic findings in patients with necrotizing pneumonia and to evaluate clinical significance of the extent of necrosis. We reviewed medical records and retrospectively analysed CT scans and follow-up chest radiographs of 22 patients with necrotizing pneumonia, confirmed by biopsy (n = 7) and culture (n = 15). Inclusion criteria for necrotizing pneumonia was necrotic low attenuation, with or without cavitation on postcontrast enhanced CT scan. The study group included 15 men and seven women, aged 11-66 years (average: 47 years). The pathogens of necrotizing pneumonia were Klebsiella spp (n = 7), Enterobacter spp (n = 5), Actinomyces spp (n = 4), Pseudomonas spp (n = 4), Nocardia spp (n = 4), and others (n = 5). Average duration of pneumonia was 4.1 months. On CT scan, pneumonic consolidations were well-marginated in 14 patients and there were cavities on initial CT scan in 16 cases. Margins of the necrotic portion on CT scan were well-demarcated in majority of the patients (16/22). Low attenuation areas on initial CT scan resulted in cavitation, fibrosis and volume loss as shown on follow-up chest radiographs. The larger the necrotic areas on CT, the more the volume loss was. CT findings of necrotizing pneumonia were well-marginated air-space consolidation with low attenuation area, with or without cavity. The extent of necrotic area was closely related with the degree of fibrotic change later on. CT is important tool for diagnosis and prediction of parenchymal damage in necrotizing pneumonia

    Cutaneous necrotizing vasculitis (CNV) is a complex multisystem disease generally involving the skin and mucous membranes, often accompanied by renal, gastrointestinal, pericardial, neurological, and articular signs and symptoms. CNV may be idiopatical or occur in association with a drug, infection, or underlying disease. CNV has been shown in patients with chronic infections (viral, bacterial, protozoa, helminthic), serum sickness, a variety of collagen vascular diseases (systemic lupus erythematous, Sjögren's syndrome, rheumatoid arthritis, Behçet's disease) hyperglobulinemic states, cryoglobulinemia, bowel bypass syndrome, ulcerative colitis, cystic fibrosis, primary biliary cirrhosis and HIV infection. Association with malignancies is not frequent. Lymphoproliferative disorders (Hodgkin's disease, mycosis fungoides, lymphosarcoma, adult T-cell leukemia, multiple mieloma) and solid tumors (lung cancer, colon carcinoma, renal, prostate, head and neck cancer and breast cancer) may be associated with CNV. Whenever possible, treatment is directed at the elimination of the cause. In other cases after adequate laboratory screening local and systemic therapy are recommended.

    Full Text Available Necrotizing sialometaplasia (NSM is a rare benign, inflammatory disease of both major and minor salivary glands, although more commonly reported in the minor glands of the palate. The characteristic clinical presentation can perplex the clinician and may be mistaken for a malignant neoplasm, such as mucoepidermoid carcinoma, as well as invasive squamous cell carcinoma. The clinical and histological similarity between this entity and a malignant lesion may result in unnecessary or mis-treatment. Though clinically mimics malignancy, NSM is considered to be a self-limiting disease, and takes about 3-12 weeks to resolve. Majority of the case resolves itself or by supportive and symptomatic treatment. Surgical intervention is rarely required in NSM except the diagnostic biopsy. Herein we report the clinical, histopathological feature and surgical management of a case of NSM of hard palate in a young adult male.

    An acute to chronic idiopathic necrotizing meningoencephalitis was diagnosed in 5 Chihuahua dogs aged between 1.5 and 10 years. Presenting neurologic signs included seizures, blindness, mentation changes, and postural deficits occurring from 5 days to 5.5 months prior to presentation. Cerebrospinal fluid analyses from 2 of 3 dogs sampled were consistent with an inflammatory disease. Magnetic resonance imaging of the brain of 2 dogs demonstrated multifocal loss or collapse of cortical gray/white matter demarcation hypointense on T1-weighted images, with T2-weighted hyperintensity and slight postcontrast enhancement. Multifocal asymmetrical areas of necrosis or collapse in both gray and white matter of the cerebral hemispheres was seen grossly in 4 brains. Microscopically in all dogs, there was a severe, asymmetrical, intensely cellular, nonsuppurative meningoencephalitis usually with cystic necrosis in subcortical white matter. There were no lesions in the mesencephalon or metencephalon except in 1 dog. Immunophenotyping defined populations of CD3, CD11d, CD18, CD20, CD45, CD45 RA, and CD79a immunoreactive inflammatory cells varying in density and location but common to acute and chronic lesions. In fresh frozen lesions, both CD1b,c and CD11c immunoreactive dendritic antigen-presenting cells were also identified. Immunoreactivity for canine distemper viral (CDV) antigen was negative in all dogs. The clinical signs, distribution pattern, and histologic type of lesions bear close similarities to necrotizing meningoencephalitis as described in series of both Pug and Maltese breed dogs and less commonly in other breeds.

    During production of sugar beet (Beta vulgaris) seeds in greenhouses, workers frequently develop allergic symptoms. The aim of this study was to identify and characterize possible allergens in sugar beet pollen. Sera from individuals at a local sugar beet seed producing company, having positive SPT and specific IgE to sugar beet pollen extract, were used for immunoblotting. Proteins in sugar beet pollen extracts were separated by 1- and 2-dimensional electrophoresis, and IgE-reactive proteins analyzed by liquid chromatography tandem mass spectrometry. A 14 kDa protein was identified as an allergen, since IgE-binding was inhibited by the well-characterized allergen Che a 2, profilin, from the related species Chenopodium album. The presence of 17 kDa and 14 kDa protein homologues to both the allergens Che a 1 and Che a 2 were detected in an extract from sugar beet pollen, and partial amino acid sequences were determined, using inclusion lists for tandem mass spectrometry based on homologous sequences. Two occupational allergens were identified in sugar beet pollen showing sequence similarity with Chenopodium allergens. Sequence data were obtained by mass spectrometry (70 and 25%, respectively for Beta v 1 and Beta v 2), and can be used for cloning and recombinant expression of the allergens. As for treatment of Chenopodium pollinosis, immunotherapy with sugar beet pollen extracts may be feasible.

    2014-09-01

    Full Text Available Crop yield estimation is one of the most important parameters for information and resources management in precision agriculture. This information is employed for optimizing the field inputs for successive cultivations. In the present study, the feasibility of sugar beet yield estimation by means of machine vision was studied. For the field experiments stripped images were taken during the growth season with one month intervals. The image of horizontal view of plants canopy was prepared at the end of each month. At the end of growth season, beet roots were harvested and the correlation between the sugar beet canopy in each month of growth period and corresponding weight of the roots were investigated. Results showed that there was a strong correlation between the beet yield and green surface area of autumn cultivated sugar beets. The highest coefficient of determination was 0.85 at three months before harvest. In order to assess the accuracy of the final model, the second year of study was performed with the same methodology. The results depicted a strong relationship between the actual and estimated beet weights with R2=0.94. The model estimated beet yield with about 9 percent relative error. It is concluded that this method has appropriate potential for estimation of sugar beet yield based on band imaging prior to harvest

    Necrotizing fasciitis is a serious infection that originates in the subcutaneous tissues. Although many reports have been published about necrotizing infections of other anatomical sites, retroperitoneal necrotizing soft tissue infection is a rare entity that has been described in only a few case reports. The etiology and clinical course of retroperitoneal necrotizing fasciitis can be variable and it is often difficult to identify the etiology of the infective process. We report a 58-year-old man with rapidly progressive, gas-producing, necrotizing inflammation in the retroperitoneum, complicated with genital involvement resembling Fournier gangrene. The patient was managed successfully by aggressive drainage, debridement, and sequential laparotomies to track and control the extensive necrosis of the retroperitoneum and perineum, in addition to systemic care to control sepsis. After his general condition stabilized, early rectosigmoid adenocarcinoma was identified and resected curatively. He remained well at follow up, six months after discharge. In retrospect, the trigger of the disease process was unclear. Although it was believed possibly to be due to the colon lesion, adenocarcinoma of the rectosigmoid colon was identified and the patient was managed successfully. Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

    2008-11-01

    A sugar beet (Beta vulgaris) fosmid library from the doubled haploid accession KWS2320 encompassing 115 200 independent clones was constructed and characterized. The average insert size of the fosmid library was determined by pulsed field gel electrophoresis to be 39 kbp on average, thus representing 5.9-fold coverage of the sugar beet genome (758 Mbp). PCR screening of plate pools with primer pairs against nine sugar beet genes supported the insert size estimation. BLAST searches with 2951 fosmid end-sequences originating from 1510 clones (1536 clones attempted) revealed little contamination with organellar DNA (2.1% chloroplast DNA, 0.3% mitochondrial DNA). The sugar beet fosmid library will be integrated in the presently ongoing efforts to determine the sequence of the sugar beet genome. Fosmids will be publicly available in the format of plate pools and individual clones.

    The use of beet for beef production after ensiling together with maize was studied in two experiments involving 112 and 114 White-blue bulls. In the first experiment maize silage (I) was compared with mixed silage of maize and fodder beet (II) or sugar beet (III) (ratio: 2/1, DM-basis). In the second experiment maize silage (I) was compared with mixed silage of 0.67 maize and 0.33 sugar beet (II) or maize silage and fresh sugar beet (ratio: 2/1, DM basis) (III) or fresh sugar beet and potatoes afterwards at 4% of the live weight and maize silage (IV). From day 113 onwards, mixed silage was also fed to group III and sugar beet were replaced by raw potatoes in group IV. The basic diet was always supplemented with concentrate at 0.75% of the live weight. In experiment 1 live weight gain was slightly but not significantly higher for the mixed silages, although daily net energy intake per kg metabolic weight was higher. Feed efficiency was not significantly different among groups. Mixed silages yielded more fat in the carcass. In the second experiment initial growth rates were not significantly affected by the use of sugar beet or mixed silages. Afterwards, they were increased in comparison with maize silage. Also in this experiment, daily net energy intake was increased by sugar beet, or by potatoes. Energy efficiency did not differ among groups. This experiment did not show significant differences for the carcass composition. However, EUROP fatness score was higher for diets containing one third sugar beet. Most meat quality parameters were not affected by the diets. Only the lightness was different between III and IV.

    Full Text Available Background : Necrotizing fasciitis (NF is a surgical emergency. It is a rapidly progressing infection of the fascia and subcutaneous tissue and could be fatal if not diagnosed early and treated properly. NF is common in the groin, abdomen, and extremities but rare in the neck and the head. Cervical necrotizing fasciitis (CNF is an aggressive infection of the neck and the head, with devastating complications such as airway obstruction, pneumonia, pulmonary abscess, jugular venous thrombophlebitis, mediastinitis, and septic shock associated with high mortality. Aim : To assess the presentation, comorbidities, type of infection, severity of disease, and intensive care outcome of CNF. Methods : Medical records of the patients treated for NF in the surgical intensive care unit (SICU from January 1995 to February 2005 were reviewed retrospectively. Results : Out of 94 patients with NF, 5 (5.3% had CNF. Four patients were male. The mean age of our patients was 41.2 ± 14.8 years. Sixty percent of patients had an operative procedure as the predisposing factor and 80% of patients received nonsteroidal anti-inflammatory drugs (NSAIDs. The only comorbidity associated was diabetes mellitus (DM in 3 patients (60%. Sixty percent of the cases had type1 NF. Mean sequential organ failure assessment (SOFA score on admission to the ICU was 8.8 ± 3.6. All patients had undergone debridement at least two times. During the initial 24 h our patients received 5.8 ± 3.0 l of fluid, 2.0 ± 1.4 units of packed red blood cells (PRBC, 4.8 ± 3.6 units of fresh frozen plasma (FFP, and 3.0 ± 4.5 units of platelet concentrate.

    Being a multi-talented crop, sugar beets are increasingly convincing biogas plant owners with their positive properties. In a mixture of substrates, they are a perfect partner for biogas production as they can push gas yield. In breeding, the experts mainly focus on increasing dry matter yield. There is a close correlation with sugar yield. The market already offers a multitude of highly performing sugar beet varieties for most diverse cropping conditions. The beets are harvested and transported from the field to the biogas plant with harvesting and transport technology which has proved its efficiency for many years. Other than harvested for other purposes, sugar beet for biogas production are stripped of their leaves instead of being topped. Stocking sugar beet at the biogas plant is a quite demanding issue. Sugar beets may be stocked as ensiled, whole beet, as pulp, or as crushed beet in mixed silage. There is a whole range of most diverse storage and crushing concepts. When used as a substrate for biogas production, sugar beet mostly need to be cleaned and stones need to be discarded before feeding the beets into the digester. In the meanwhile, the market offers a large choice of cleaning technique to pave the ways for sugar beets as a substrate. (orig.)

    Full Text Available Necrotizing fasciitis, caused by Streptococcus pneumoniae, is an extremely rare and life-threatening bacterial soft tissue infection. We report a case of early necrotizing fasciitis associated with Streptococcus pneumoniae infection in a 26-year-old man who was immunocompromised with mixed connective tissue disease. The patient presented with acute, painful, erythematous, and edematous skin lesions of his right lower back, which rapidly progressed to the right knee. The patient underwent surgical exploration, and a diagnosis of necrotizing fasciitis was confirmed by pathological evidence of necrosis of the fascia and neutrophil infiltration in tissue biopsies. Cultures of fascial tissue biopsies and blood samples were positive for Streptococcus pneumoniae. To our knowledge, this is the first report of necrotizing fasciitis resulting from Streptococcus pneumoniae diagnosed at early phase; the patient recovered well without surgical debridement.

    Full Text Available Spontaneous pneumothorax is a serious complication of pulmonary tuberculosis that requires immediate treatment. Necrotizing fasciitis is a serious, rapidly progressive infection of the subcutaneous tissue and fascia, most related to trauma or surgery. Here, we report a case of pulmonary tuberculosis with spontaneous pneumothorax. A standard procedure of tube thoracostomy was performed for lung re-expansion. Two days after the tube was removed, necrotizing fasciitis developed from the puncture site. Computed tomography of the chest showed focal thickness with gas formation and loss of the fat plane over the chest wall, which is compatible with the diagnosis of necrotizing fasciitis. Aggressive treatment was given, including emergency fasciectomy and adequate systemic antibiotic and antituberculous treatment. The necrotizing fasciitis was successfully treated. The patient was discharged and sent home with maintenance antituberculous therapy.

    Necrotizing enterocolitis (NEC) is a clinical syndrome of ischemic necrosis of the bowel of multiple etiological factors that include the presence of intestinal ischemia, abnormal bacterial flora, and intestinal mucosal immaturity. Numerous reports have implied that the fecal microflora may contribute to the pathogenesis of NEC. A broad range of organisms generally found in the distal gastrointestinal tract have been recovered from the peritoneal cavity and blood of infants with NEC. The predominant organisms include Enterobacteriaceae (i.e., Escherichia coli, Klebsiella pneumoniae) , Clostridium spp., enteric pathogens (salmonellae, Coxsackie B2 virus, coronavirus, rotavirus), and potential pathogens (Bacteroides fragilis). The goals of the initial management is preventing ongoing damage, restoring hemostasis, and minimizing complications. Medical management includes withholding oral feeding, placement of nasogastric tube, abdominal decompression, paracentesis, vigorous intravenous hydration containing electrolytes and calories, support of the circulation, administration of antibiotics, and surveillance for deterioration or complications that require surgical intervention. Indications for surgery include clinical deterioration, perforation, peritonitis, obstruction, and abdominal mass. Prevention remains crucial to decrease the incidence of NEC. Preventive methods include cautious feeding regimens, the use of maternal breast milk, and the use of probiotics.

The shaft of the penis and the scrotum were swollen and tender. No skin necrosis was observed and no crepitus was palpable. Serum white count (WBC) was 29.5 × 10(3)/μL. A CT scan showed gas in the corpus spongiosum. Antibiotics were started with IV metronidazole, vancomycin, and piperacillin/tazobactam. Metronidazole was then replaced by clindamycin. Exploration was performed but no necrotic tissue was identified. Cystourethroscopy revealed dusky looking urethra. A suprapubic tube and a urethral catheter were placed in the bladder. WBC trended down to 13.9 × 10(3)/μL on the fourth postoperative day. Urine culture grew Aerococcus urinae and blood cultures grew Alpha Hemolytic Streptococcus. On the sixth day, the patient was feeling worse and WBC increased. MRI revealed absent blood flow to the corpus spongiosum. Urethroscopy revealed necrosis of the urethra. Urethrectomy was performed via perineal approach. The patient immediately improved. The patient was discharged on the sixth postoperative day to continue ampicillin/sulbactam IV every 6 hours for a total of 4 weeks from the day of urethrectomy.

    Necrotizing enterocolitis (NEC) has largely been present in neonatal intensive care units for the past 60 years. NEC prevalence has corresponded with the continued development and sophistication of neonatal intensive care. Despite major efforts towards its eradication, NEC has persisted and appears to be increasing in some centers. The pathophysiology of this disease remains poorly understood. Several issues have hampered our quest to develop a better understanding of this disease. These include the fact that what we have historically termed 'NEC' appears to be several different diseases. Animal models that are commonly used to study NEC pathophysiology and treatment do not directly reflect the most common form of the disease seen in human infants. The pathophysiology appears to be multifactorial, reflecting several different pathways to intestinal necrosis with different inciting factors. Spontaneous intestinal perforations, ischemic bowel disease secondary to cardiac anomalies as well as other entities that are clearly different from the most common form of NEC seen in preterm infants have been put into the same database. Here I describe some of the different forms of what has been called NEC and make some comments on its pathophysiology, where available studies suggest involvement of genetic factors, intestinal immaturity, hemodynamic instability, inflammation and a dysbiotic microbial ecology. Currently utilized approaches for the diagnosis of NEC are presented and innovative technologies for the development of diagnostic and predictive biomarkers are described. Predictions for future strategies are also discussed.

    Full Text Available During 2003-2004, field surveys were realized to observe the distribution of sugar beet aphid, Pemphigus fuscicornis (K o c h (Sternorrhyncha Pemphigidae in southwestern Slovakia. The research was carried out at 60 different localities with altitudes 112-220 m a. s. l. Sugar beet root aphid was recorded at 30 localities. The aphid was recorded in Slovakia for the first time, but its occurrence was predicted and symptoms and harmfulness overlooked by now. The presence of P. fuscicornis was investigated on roots of various plants from Chenopodiaceae. The most important host plants were various species of lambsquarters (above all Chenopodium album. Furthermore sugar beet (Beta vulgaris provar. altissima, red beet (B. vulgaris provar. conditiva and oraches (Atriplex spp act as host plants. Infestation of sugar beet by P. fuscicornis never exceeded 5% at single locality in Slovakia. Dry and warm weather create presumptions for strong harmfulness. In Slovakia, Chenopodium album is a very important indicator of sugar beet aphid presence allowing evaluation of control requirements. During the study, the larvae of Thaumatomyia glabra (Diptera: Chloropidae were detected as important natural enemies of sugar beet aphid. The species occurred at each location evaluated.

    Beet sugar contains an off-aroma, which was hypothesized to generate expectations on the acceptability of a product made with beet sugar. Thus, the objective of this study was to assess the impact of information about the sugar source (beet vs. cane) on the overall liking of an orange-flavored beverage. One hundred panelists evaluated an orange-flavored powdered beverage mix and beverage made with beet and cane sugars using a 5-phase testing protocol involving a tetrad test and hedonic ratings performed under blind and informed conditions. Tetrad test results indicated that there was a significant difference (P beet sugar and cane sugar; however, no difference was found between the beverage made with beet sugar and cane sugar. Hedonic ratings revealed the significance of information conditions on the panelists evaluation of sugar (F = 24.67, P sugar source information in a beverage product. Based on concerns with the use of beet sugar expressed in the popular press, there may be a subgroup of the population that has a preconceived bias about sugar sources due to their prior experiences and knowledge and, thus, would be influenced by labels indicating the sugar source used in a product. © 2014 Institute of Food Technologists®

  1. Theory of Vibrations of Sugar Beet Leaf Harvester Front-Mounted on Universal Tractor

    Full Text Available The harvest and transport of sugar beet leaves during harvesting can be considered a current task in the area of sugar beet growing system development. A rotary sugar beet leaf cutting mechanism is used for achieving the significant increase in the harvester forward speed during harvest. This leads to intensive vibrations of the topping mechanism in the longitudinal vertical plane causing the decrease of harvest quality. Therefore, it is necessary to analytically determine the effect of kinematic and design parameters of the sugar beet topping mechanism front-mounted on the tractor and to discover the value of the amplitude of oscillations in the longitudinal vertical plane of its sugar beet topping mechanism. We have constructed a mathematical model of the estimated motion of this machine by means of dynamics equations in Lagrange II-kind form. A system consisting of two non-linear differential equations was obtained by developing the equivalent scheme of selected generalized coordinates and by performing the necessary mathematical transformations. This system describes the vibrations of the sugar beet topping mechanism in the longitudinal vertical plane. The optimal design and kinematic parameters of the sugar beet topper mechanism front-mounted on the tractor were determined by means of our own software and numerical solution of the differential equation system, which allows the reduction of mentioned vibrations.

    Full Text Available The article presents the results of the research on the current state of the beet sugar subcomplex of Ryazan region in the context of the need of improving its efficiency. The study let the author determine that currently the beet sugar subcomplex of Ryazan region does not ensure domestic demand in sand sugar. However, there are reserves of providing more efficient use of soil and climate capacity as well as the productivity potential of the region. When applying the technology of field beet piling, the period of sugar production at sugar factories may be extended up to 200 days. At this, up to 51 thousand tons of sand sugar can be produced. This amount will completely cover the annual demand for sugar in Ryazan region. In order to further study the feasibility of this approach, zoning was carried out and let allocate the zones of beet seeding. As a result, it was determined that a number of areas are far removed from the place of treatment, and in terms of transportation costs minimization the sugar beet cultivation in these areas is not rational. As an alternative, the author proposes to consider the possibility of building a new sugar factory in Ryazhsky district with the processing capacity of 1,000 tons of sugar beet per day. Taking this into account, the recommended acreage of sugar beet by districts and zones of raw material supply were obtained through corresponding calculations.

    Hydrogen production needs to be based on renewable resources in order to be sustainable. Sugar beet is an ideal raw material for fermentative production of hydrogen in the EU and possibly in the USA due to its environmental profile and its potential availability in these areas. In this work, the fermentative production of hydrogen from sucrose of analytical grade and sugar beet extract by pure cultures of Caldicellulosiruptor saccharolyticus was investigated, under uncontrolled and controlled conditions. In the first case, growth of pure cultures of C. saccharolyticus on sucrose derived from sugar beet was compared to growth of the microorganism on sucrose of analytical grade. The production of hydrogen and organic acids (acetate and lactate) from sugar beet was largely equal to or slightly higher than the production of the control. In the second case, fermentation of sugar beet extract at sucrose concentration 10 g/l was comparable to the fermentation on pure sucrose except that the hydrogen yield was slightly higher on sugar beet extract. In particular, hydrogen yields of 2.9 and 3.0 mol/mol hexose were determined in fermentations of sucrose and sugar beet extract, respectively, corresponding to 73% and 75% of the theoretical value of 4 mol hydrogen/mol hexose. Acetic acid was the main product and very low production of lactic acid was observed. (orig.)

    2003-03-01

    SUMMARY Taxonomic relationship: Type member of the genus Closterovirus, family Closteroviridae. A member of the alphavirus-like supergroup of positive-strand RNA viruses. Physical properties: Virions are flexuous filaments of approximately 1300 nm in length and approximately 12 nm in diameter that are made up of a approximately 15.5 kb RNA and five proteins. The major capsid protein forms virion body of helical symmetry that constitutes approximately 95% of the virion length. The short virion tail is assembled by the minor capsid protein, Hsp70-homologue, approximately 64-kDa protein, and approximately 20-kDa protein. Viral proteins: The 5'-most ORFs 1a and 1b encode leader proteinase and RNA replicase. The remaining ORFs 2-8 are expressed by subgenomic mRNAs that encode 6-kDa membrane protein, Hsp70 homologue, approximately 64-kDa protein, minor and major capsid proteins, approximately 20-kDa protein, and approximately 21-kDa protein, respectively. Hosts: The principal crop plants affected by Beet yellows virus (BYV) are sugar beet (Beta vulgaris) and spinach (Spinacea oleracea). In addition, BYV was reported to infect approximately 120 species in 15 families. Most suitable propagation species are Nicotiana benthamiana, Tetragonia expansa, and Claytonia perfoliata.

    Sugar beet (Beta vulgaris ssp. vulgaris) is an important crop of temperate climates which provides nearly 30% of the world's annual sugar production and is a source for bioethanol and animal feed. The species belongs to the order of Caryophylalles, is diploid with 2n = 18 chromosomes, has an estimated genome size of 714-758 megabases and shares an ancient genome triplication with other eudicot plants. Leafy beets have been cultivated since Roman times, but sugar beet is one of the most recently domesticated crops. It arose in the late eighteenth century when lines accumulating sugar in the storage root were selected from crosses made with chard and fodder beet. Here we present a reference genome sequence for sugar beet as the first non-rosid, non-asterid eudicot genome, advancing comparative genomics and phylogenetic reconstructions. The genome sequence comprises 567 megabases, of which 85% could be assigned to chromosomes. The assembly covers a large proportion of the repetitive sequence content that was estimated to be 63%. We predicted 27,421 protein-coding genes supported by transcript data and annotated them on the basis of sequence homology. Phylogenetic analyses provided evidence for the separation of Caryophyllales before the split of asterids and rosids, and revealed lineage-specific gene family expansions and losses. We sequenced spinach (Spinacia oleracea), another Caryophyllales species, and validated features that separate this clade from rosids and asterids. Intraspecific genomic variation was analysed based on the genome sequences of sea beet (Beta vulgaris ssp. maritima; progenitor of all beet crops) and four additional sugar beet accessions. We identified seven million variant positions in the reference genome, and also large regions of low variability, indicating artificial selection. The sugar beet genome sequence enables the identification of genes affecting agronomically relevant traits, supports molecular breeding and maximizes the plant

    Full Text Available Food products from vegetable raw materials play a special role in the food industry. Sugar is one of the strategically important products. The significance of its is great due to its wide use in confectionery, bakery, liquor, canning, biochemical, pharmaceutical and other branches of human activity. Effective development of the domestic sugar industry depends on the terms of competition with European partners. Production of granulated sugar includes a significant amount of energy-intensive and technologically complex operations, one of which is the extraction of sucrose from beet chips by means of hot countercurrent extraction. The most important criterion for the extraction process efficiency evaluation is the coefficient of molecular diffusion. The efficiency of using of beet chips thermo chemical processing before extraction depending on the quality of processed beet was investigated. It was found out that when using a low quality beet the diffusion coefficient decreases compared to healthy beet. The use of solutio ns of some salts for beet chips heat treatment has an overall positive effect on the diffusion coefficient. A method for recovering sucrose from beet with the use of compounds of Al2(SO4, Ca(SO4, and (NH42SO4 as the extractants was proposed. It was found out that beet samples treatment with solutions of proposed salts provides a sucrose smooth transition from the pores of sugar beet tissue into the extractant due to intense convective washout. It is caused by the high degree of tissue cells plasmolysis achieved in its processing with solutions of proposed reagents. The results obtained indicate a significant increase of the sucrose diffusion coefficient in the ammonium sulfate solution used as the extractant.

    Main purpose of the project is the process improvement to acquire the full potential of sugar beet based biomethane production. This covers the optimization of breeding and cultivation, as well as improvements of the overall logistic and production process. The project results show that breeding of regional adapted sugar beets can lead to higher yields in cultivation as well as technical enhancements within the biogas production chain can lower the production costs. Both approaches are part of an overall optimization of sugar beets for biomethane production. Project findings indicate a competitive position in comparison to biomethane based on different agricultural feedstock. (orig.)

    Purpose: The purpose was to determine whether the diffusion weighted imaging (DWI) was able to differentiate necrotic tumor or metastatic lesions from infected necrotic lesions such as abscesses and necrotic lymphadenitis in the neck. Materials and methods: DWI was performed on 37 consecutive patients with 85 head and neck necrotic and cystic lesions. The lesions were classified into four categories: metastatic lymph node involvement including lymphoma, necrotic tumor, abscesses and necrotic lymphadenitis. Each lesion was histopathologically studied and proved. Results: In 12 patients, there were 35 necrotic lymphadenitis (necrotic tuberculosis lymphadenitis, n = 18; necrotic nonspecific suppurative lymphadenitis, n = 17). Of the 15 necrotic metastatic nodes, 11 lesions were lymphomatous involvement and 4 lesions were other tumor involvement. Other 11 patients have abscesses. Thirteen primary tumoral necrotic lesions arose in the neck of nine patients. All of the abscesses and necrotic lympadenitis showed hyperintensity on DWI, in contrast to necrotic tumor and necrotic nodal metastasis that showed hypointensity on DWI. DWI successfully differentiated metastatic nodes and necrotic tumors from necrotic lymphadenitis and abscesses. Conclusion: DWI may be supportive for differentiating necrotic tumor lesions such as necrotic tumor and metastatic necrotic nodes from the infective necrotic lesions such as necrotic lymphadenitis and abscesses in the head and neck.

    The small vessel's necrotizing angiitis (necrotizing microangiitis (NMA), leucocytoclastic angiitis) form a continuous spectrum from the exclusively cutaneous forms of Gougreot, to those which seriously affect the viscera, as the very acute and fatal cases of Zeek, passing through a series of intermediate phases, in which Schönlein-Henoch's purpura is found. In all of these clinical forms, the existence of an allergic mechanism has been suggested from their origin itself and in 1964 Alarcón-Segovia and Brown grouped them under the common denominator of allergic angiitis. Later investigations are far from completely confirming this hypothesis. In isolated cases, the clinical sequence corroborates the hypothesis of a bacterian aetiology (local septic focus), but in the Schónlein-Henoch purpura it has not been proven that there is a greater streptococcus beta-haemolytic frequency is the throat nor a greater number of antibodies in the serum than in normal children or those affected by illnesses not related to rheumatic fever. The aetiologic role of drugs and food is very difficult to prove. The anatomopathologic similarity between the Arthus reaction, the serum sickness and the spontaneous human NMA have led to the hypothesis that the NMA are immunocomplex (IC) diseases. In order to try to prove this, basically three techniques have been used: Direct immunofluorescence to show the IC tissue deposits, and mixed cryoglobulinemia and the serum's anti-complementary activity for the circulating IC. Direct immunofluorescence shows, in approximately 50% of the cases, the presence of IgG and C3 in the damaged vessels (also IgM with frequency). But, are these found combined as complexes? Parish, in some cases of presumably post-bacterial angiitis, has shown the simultaneous presence of the bacterian antigen and the Ig. The direct immunofluorescence negativity can be due to: (1) The IC being rapidly eliminated by the neutrophils; (2) the fact that these are nonimmunologic

    Full Text Available Introduction. Necrotizing soft tissue infection (NSTI is a life-threatening condition, characterized by widely spread necrosis of skin, subcutaneous fat, fascia and muscles. Treatment involves surgical debridement and broad-spectrum antimicrobial therapy. Mortality is still high due to diagnostic delays. NSTI is rare in general population, there are even less literature data of this condition in pregnancy. Timely diagnosis and therapy is crucial for outcome of these patients. Clinicians should have in mind NSTI in patients with perianal infections, especially in cases where immunosuppressive role of pregnancy is present. Case outline. We present a case of a 21-year-old pregnant woman with NSTI spreading from perianal region. The patient was admitted to hospital in the 31st week of otherwise healthy twin pregnancy one day after incision of perianal abscess. At admission she was examined by a gynecologist; vital signs were stable, laboratory results showed the presence of infection. She was referred for another surgical procedure and broad-spectrum antibiotics were prescribed. The next morning the patient complained of intense abdominal pain. Clinical exam revealed only discrete redness of the skin tender on palpation, crepitating. She was immediately referred to surgery. Intraoperative findings revealed massive soft tissue infection spreading up to the chest wall. Wide skin incisions and debridement were performed. The patient developed septic shock and after initial resuscitation gynecologist confirmed intrauterine death of twins and indicated labor induction. Over the next few days the patient’s general condition improved. On several occasions the wounds were aggressively debrided under general anesthesia, which left the patient with large abdominal wall defect. Twenty-three days after the initial operation, the defect was reconstructed with partial-thickness skin grafts, providing satisfactory results. Conclusion. Diagnosis and outcome of

    Full Text Available Purified glucosylceramide from beet extract (beet GlcCer and beet extract containing an equal amount of GlcCer were administered orally to ultra violet B (UVB-irradiated mice, and differences in the protective effects against skin barrier dysfunction caused by UVB irradiation were compared. In the beet GlcCer group, epidermal thickening and the decrease in stratum corneum (SC ceramide content caused by UVB irradiation were reduced. In the group that was orally administered beet extract containing glucosylceramide, effects similar to those in the beet GlcCer group were observed. Oral administration of beet GlcCer had no obvious effects against an increase in TEWL or decrease in SC water content after UVB irradiation, but there was improvement in the beet extract group. Oral administration of beet GlcCer is effective in improving skin barrier function in UVB-irradiated mice. Beet extract contains constituents other than GlcCer that are also effective in improving skin barrier function.

    Association mapping promises to overcome the limitations of linkage mapping methods. The main objective of this study was to examine the applicability of multivariate association mapping with an empirical data set of sugar beet. A total of 111 diploid sugar beet inbreds was selected from the seed parent heterotic pool to represent a broad diversity with respect to sugar content (SC). The inbreds were genotyped with 26 simple sequence repeat markers chosen according to their map positions in proximity to previously identified quantitative trait loci for SC. For SC and beet yield (BY), the genotypic variances were highly significant (P sugar beet breeding context for detection of marker-phenotype associations. Furthermore, based on our results multivariate association mapping can be recommended as a promising tool to discriminate with a high mapping resolution between pleiotropy and linkage as reasons for co-localization of marker-phenotype associations for different traits.

    2016-01-01

    Full Text Available Molasses is an important by-product of sugar beet or sugar cane refining industry and it was one of the first sweeteners used in human nutrition. Sugar cane molasses has unique characteristics that can make it suitable for application in food industry, especially in confectionery and bakery products. On the other hand, sugar beet molasses has not had greater application in the human diet, primarily because of its strong smell and taste of the beet, which makes it unattractive for consumption. Since recent investigations showed that sugar beet molasses can be used as a hypertonic solution in osmotic dehydration of different materials of plant and animal origin, the objective of this work was to review recently studied sugar beet molasses in terms of its applications in osmotic dehydrations of fruits and vegetables. Previous studies showed that sugar beet molasses is an excellent medium for osmotic dehydration of fruits and vegetables (apple, carrot, plum, etc. primarily due to a high content of dry matter (80%, w/w and specific nutrient content. An important advantage of using sugar beet molasses as a hypertonic solution is an enrichment of the dehydrated material in minerals and vitamins, which penetrate from molasses into the plant tissue. Concentration of sugar beet molasses solution and immersion time had the biggest influence on the process of osmotic dehydration of fruit and vegetables, while the temperature of the solution was the least influential parameter. The effect of immersion time on the kinetics of osmotic dehydration in sugar beet molasses increases with an increase in concentration of hypertonic solution. Fruit and vegetables dehydrated in sugar beet molasses had a higher dry matter content compared to samples treated in sucrose solutions. Besides, application of sugar beet molasses in osmotic dehydration of fruits and vegetables had some other advantages such as lower cost of molasses compared to sugar and its liquid aggregate

    The aims of this paper were to review our experience with necrotizing fasciitis at Middlemore Hospital and to define the trends in incidence, inpatient mortality and microbiological profile. A computerized search of the electronic medical records was undertaken to identify adult patients with a diagnosis of necrotizing fasciitis between January 2000 and December 2010. A retrospective review of the clinical records was performed. Of the 138 patients with necrotizing fasciitis identified, 129 had their diagnosis confirmed at operation. The mortality at 30 days was 20.3% (95% confidence interval (CI) 13.9%-28.0%). There was a significant reduction in hospital mortality in each successive year of the study period with an odds ratio of 0.84 (95% CI 0.71-0.98, P = 0.03). A pattern of increasing incidence was noted until February 2004 (95% CI September 2002-July 2005). This was followed by a significant decrease in incidence. The empirical antibiotic regime of clindamycin, gentamicin and penicillin provides satisfactory cover against 95% of the causative pathogens. This represents the largest single-centre published case series in New Zealand. Despite concerns of increasing incidence and mortality associated with necrotizing fasciitis in New Zealand, the experience in South Auckland shows a decrease in incidence of necrotizing fasciitis since 2004 and a statistically significant decreasing trend in hospital mortality. © 2015 Royal Australasian College of Surgeons.

    To study the occurrence of bacterial translocation and to assess the impact of breastfeeding on bacterial translocation in the animal model of necrotizing enterocolitis. A total of 20 neonate Sprague-Dawley rats were enrolled in the study. Rats were randomly allocated into either control or study group just after birth. Ten newborn rats in the control group were left with their mother to be breast-fed. In contrary, necrotizing enterocolitis group consisted of neonates that were separated from their mothers, housed in an incubator and were gavaged with a special rodent formula three times daily. Survival rates, weight changes, and morphologic scoring obtained after microscopic evaluation were determined as microbiologic evaluation criteria. All the rats in the control group survived, while 1 (10 %) rat died in the necrotizing enterocolitis group. Mortality rates of the two groups were similar. All the formula-fed animals in the necrotizing enterocolitis group had significant weight loss compared to the breast milk-fed rats in the control group (pmicrorganisms in the bowel pass through the intestinal barrier and reach the liver and the spleen via the hematogenous route. This condition is closely related to the impairment of physiological and functional features of the intestinal barrier and is independent from the degree of intestinal injury. Bacterial translocation should be remembered in cases suspected of necrotizing enterocolitis, and a rapid and effective treatment algorithm should be applied in such circumstances (Tab. 3, Fig. 3, Ref. 21).

    Crystal containing cells widely distributed in plant tissues, though the origin of the crystals and their functions are still opened to question. Membrane vesicles in beet leaves are visible in electronic microscope. They originate in cytoplasm and penetrate into vacuole by pinocytosis with participation of tonoplast. In light microscope, vesicles are luminous likewise crystals in crystal cells. Such vesicles-"crystals" fulfill crystal cells also. The content of vesicles-"crystals" are electronic transparent at every path of leaf development. It was proposed that distinct vesicles-"crystals" in cytoplasm and vacuole and mass of them in crystal cells, vein bundles, and epidermal cells--all of them are lytic compartments. Later, obviously, true crystals are formed.

    Germination and sugar beet yield after seed stimulation were investigated. The seeds came from the energ'hill technology and were subject to laser irradiation. The experiments were conducted in the laboratory and field conditions. Lengthening of germinal roots and hypocotyls was observed. A positive effect of the stimulation on the morphological features was observed for the Eh seeds and laser irradiation applied in a three-fold dose. The energ'hill seeds exhibited a significantly higher content of carotenoids in seedlings and an increase in the content of chlorophylls. Laser light irradiation favourably modified the ratio of chlorophyll a to b. The leaves and roots of plants developed from the energ'hill and irradiated seeds were characterized by higher dry matter content thanin non-stimulated seeds. Seed stimulation had a positive influence on yielding and the saccharose content.

    Full Text Available The aim of research was obtaining sugar beet haploids via gyno-genesis and their micropropagation. Haploids were obtained by ovule culture from fourteen diploid, monogerm, fertile genotypes. On the tested nutrient media genotypes exhibited different gynogenic potential. Eight haploid plant were chosen for further investigation and after development of first leaves put on micropropagation medium. The presence of cyto-kinin in medium stimulated development of axillary buds, while in some genotypes adventitious buds developed as well. Multiplication rate was not consistent, although number of developed plants grew after each sub-cultivation. Differences in plant multiplication started to differ after four subcultures. By testing of differences between correlation coefficients, i.e. multiplication rate during six subcultivations, it was determined that they significantly differ between tested genotypes.

    Although beet and cane sugar sources have nearly identical chemical compositions, the sugars differ in their volatile profiles, thermal behaviors, and minor chemical components. Scientific evidence characterizing the impact of these differences on product quality is lacking. The objective of this research was to determine whether panelists could identify a sensory difference between product matrices made with beet and cane sugar sources. Sixty-two panelists used the R-index by ranking method to discern whether there was a difference between 2 brands of beet and 2 brands of cane sugars in regard to their aroma and flavor, along with a difference in pavlova, simple syrup, sugar cookies, pudding, whipped cream, and iced tea made with beet and cane sugars. R-index values and Friedman's rank sum tests showed differences (P beet and cane sugars in regard to their aroma and flavor. Significant differences between the sugar sources were also identified when incorporated into the pavlova and simple syrup. No difference was observed in the sugar cookies, pudding, whipped cream, and iced tea. Possible explanations for the lack of difference in these products include: (1) masking of beet and cane sensory differences by the flavor and complexity of the product matrix, (2) the relatively small quantity of sugar in these products, and (3) variation within these products being more influential than the sugar source. The findings from this research are relevant to sugar manufacturers and the food industry as a whole, because it identifies differences between beet and cane sugars and product matrices in which beet and cane sugars are not directly interchangeable. © 2014 Institute of Food Technologists®

  6. Feasibility of converting a sugar beet plant to fuel ethanol production

    1981-04-01

    This study was performed to assess the feasibility of producing fuel ethanol from sugar beets. Sugar beets are a major agricultural crop in the area and the beet sugar industry is a major employer. There have been some indications that increasing competition from imported sugar and fructose sugar produced from corn may lead to lower average sugar prices than have prevailed in the past. Fuel ethanol might provide an attractive alternative market for beets and ethanol production would continue to provide an industrial base for labor. Ethanol production from beets would utilize much of the same field and plant equipment as is now used for sugar. It is logical to examine the modification of an existing sugar plant from producing sugar to ethanol. The decision was made to use Great Western Sugar Company's plant at Mitchell as the example plant. This plant was selected primarily on the basis of its independence from other plants and the availability of relatively nearby beet acreage. The potential feedstocks assessed included sugar beets, corn, hybrid beets, and potatoes. Markets were assessed for ethanol and fermentation by-products saleability. Investment and operating costs were determined for each prospective plant. Plants were evaluated using a discounted cash flow technique to obtain data on full production costs. Environmental, health, safety, and socio-economic aspects of potential facilities were examined. Three consulting engineering firms and 3 engineering-construction firms are considered capable of providing the desired turn-key engineering design and construction services. It was concluded that the project is technically feasible. (DMC)

    2013-01-01

    The EU imports both bioethanol and the raw material needed to produce it. Thirty percent of bioethanol is produced from sugar beets in the EU. However, sugar beet cultivated area and yields have fallen due to the 2006 sugar regime reform. Given the potential uncertainty about the future for sugar beet farmers, biofuels may represent an alternative market. This paper analyses potential contribution to the efficiency, in terms of environmental output, of the sugar beet crop both when production is oriented toward bioethanol and regarding the use of input. An empirical application is performed in Spain by Data Envelopment Analysis (DEA). The results show that 4% of farms have full technical efficiency, while the rest have an average efficiency of 55.9%. The figures show that inputs can be reduced over 40%, and also show the low average level of input-use efficiency. In addition, it cannot be said that there is a relationship between efficiency and farm scale. The consideration of aspects such as the environmental advantages of using sugar beet production for bioethanol can open new lines of action to support this crop in the EU. In addition, boosting sugar beet production may reduce potential dependency on importation. - Highlights: ► Analysing environmental outputs from agricultural input use and production orientation to bioethanol. ► DEA is applied to model farms’ efficiency in GHG emission and nitrous oxides emissions. ► A very low level of efficiency is found in sugar beet farms. ► Efficiency increase should be supported to reduce fertilizers and pesticides. ► Environmental advantages of addressing sugar beet to bioethanol open new lines to support crops

    Full Text Available High yields with low costs require that sugar beets be kept free of weeds, during critical periods, using labor or chemical treatments. Since the critical periods for this crop in Castilla - La Mancha (Spain are unknown, the first goal of this study was to determine the effect of early and late competition on yield. The second goal was to determine the critical periods, while taking into consideration the semiarid climatic conditions of this region. Two irrigation farms located in the province of Albacete are dedicated to sugar beet cultivation. These two farms were chosen to carry out the tests March (140,000-150,000 seeds ∙ ha-1 and harvested in October. Two simultaneous and complementary experiments were carried out in each year and farm. Two scenarios were considered with eight different treatments each. In the first one (With Weeds Until - WWU, plots were infested by weeds up to a certain date. In the second one (Free of Weeds Until - FWU, plots were kept free of weeds up to a certain date. For each test, a randomised experimental blocked field was designed and there were four repetitions, each of them containing eight elemental plots (12 m2. Each plot was weeded by hand or weeds were left to grow till a definite date.The results indicated that a 1% loss of yield was reached in the early competition after 14 days, while a loss of 5% was reached after a period of 41 days after it was infested. The results also indicated that in late competition, if a crop is kept clean for 124 days and it is infested afterwards, a 1% loss is reached. However, the loss increases to 5% if the plot is kept clean for 111 days. For a 1% loss the critical period is 110 days and 70 days for a 5% loss.

    Full Text Available Common lambsquarters, cleavers, ladysthumb and wild buckwheat, chamomile, mercury, foolsparsleey and volunteer rapes are only some of the most important weeds in fooder and sugar beets. For the control of classical weed societies farmers can fall back on a limited number of active ingredients. Generally, Phenmedipham (PMP, Desmedipham (DMP and Ethofumesate are the basis of a spray sequence. They are complemented with other active ingredients depending on the specific weed situation. The newly formulated BELVEDERE® Extra combines the three mentioned active ingredients in an optimal ratio. Hence, the herbicide covers a very broad weed spectrum with an excellent efficacy on Common lambsquarters, cleavers, ladysthumb and wild buckwheat. BELVEDERE® EXTRA is a liquid, selective, and systemic herbicide. It is formulated as suspoemulsion so that a high efficacy is achieved while preserving a very good selectivity. The product allows for flexible control of leaf activity as an additive (e.g. OLEO FC is appended. Ethofumesate, which is mainly effective via the roots of the plant, belongs to a different HRAC group than Phenmedipham and Desmedipham. The high concentration of 200 g/L Ethofumesate leads to an effective resistance management especially regarding Fathen and other important weeds. Since 23rd of September 2013 BELVEDERE® extra is registered for post emergence splitting application (3 applications against annual dicotyledonous weeds. The maximum application rate per treatment is 1,3 L/ha. In combination with GOLTIX® TITAN® (Metamitron + Quinmerac or Goltix® Gold (Metamitron the weed spectrum is broadened. Basically, a timely application whose application rates are adapted to the location is essential for a good efficacy of beet herbicides.

    Sugar beet ( Beta vulgaris L. ssp. vulgaris ) is one of the most important European crops for both food and sugar production. Crop improvement has been developed to enhance productivity, sugar content or other breeder's desirable traits. The introgression of traits from Crop Wild Relatives (CWR) has been done essentially for lessening biotic stresses constraints, namely using Beta and Patellifolia species which exhibit disease resistance characteristics. Several studies have addressed crop-to-wild gene flow, yet, for breeding programs genetic variability associated with agronomically important traits remains unexplored regarding abiotic factors. To accomplish such association from phenotype-to-genotype, screening for wild relatives occurring in habitats where selective pressures are in play (i.e., populations in salt marshes for salinity tolerance; populations subjected to pathogen attacks and likely evolved resistance to pathogens) are the most appropriate streamline to identify causal genetic information. By selecting sugar beet CWR species based on genomic tools, rather than random variations, is a promising but still seldom explored route toward the development of improved crops. In this perspective, a viable streamline for sugar beet improvement is proposed through the use of different genomic tools by recurring to sugar beet CWRs and focusing on agronomic traits associated with abiotic stress tolerance. Overall, identification of genomic and epigenomic landscapes associated to adaptive ecotypes, along with the cytogenetic and habitat characterization of sugar beet CWR, will enable to identify potential hotspots for agrobiodiversity of sugar beet crop improvement toward abiotic stress tolerance.

    Full Text Available Sugar beet (Beta vulgaris L. requires fertile soils with high biological activity, rich in minerals and organic nutrients. Biological properties of soil, such as enzymatic and microbial activity, can be effectively improved through the application of humic substances. This enables an increase in growth dynamics and, consequently, in the yield. The aim of this study was to assess sugar beet germination, depending on the soil application of the humic preparation Humistar (12% of humic acids, 3% of fulvic acids as well as to assess the yield of sugar beet storage roots and the content of sugar in these storage roots, depending on soil applications of Humistar and/or foliar application of potassium fertilizer Drakar (31% K2O, 3% N. The field experiment was conducted in the soil classified as Mesic Typic Hapludalfs. Soil application of Humistar contributed to a reduction in sugar beet germination, measured as % of plants germinated within 14 days after sowing. However, the growth of plants in soil with Humistar was more intensive than in the control. A significant, positive influence of Humistar and Drakar on the yield of sugar beet roots has been found. Application of the two treatments did not produce better results than the use of each of them separately. Sugar content in roots was not affected by experimental factor. The study showed that both soil application of humic substances and the use of foliar potassium fertilizer can improve the yield of sugar beet and, consequently, increase the biological yield of sugar from storage roots.

    Full Text Available Remote sensing technology is widely used in environmental and agricultural research, and nowadays it has become a valuable and reliable source of information for the management of crop production and assessment of global supply and demands for these products. The objective of this study was to investigate the feasibility of using MODIS data and vegetation indices based on sugar beet growth monitoring. For this purpose, MODIS 8-day red and near infrared surface reflectance data at 250 m spatial resolution (MOD09Q1 collection 5 was used. Imagery data was acquired from mid-May to the end of December 2011 from the sugar beet fields located in Eqlid, Fars province, Iran. Results showed that although red and near infrared reflectance differences were relatively small at the beginning of sugar beet growing season, these differences were enhanced with canopy development and ground cover. The most red absorption and near infrared reflectance were in the maximum ground cover, and the most dramatic declines in the near infrared reflectance and relative increase in red reflectance were observed at harvest time. It was found that the RVI is able to show the status of red absorption and reflection during the growth of sugar beet canopy. The SR and NDVI change patterns demonstrated how to grow sugar beet over the growing season. Thus in the existing climate and crop management conditions in Fars province and Iran, MODIS data and vegetation indices can be used to monitor changes in canopy growth of such crops as sugar beet.

    Kuzevski Janja

    2011-01-01

    Full Text Available The aim of this study was to determine the effects of three different inoculation methods with selected Azotobacter chroococcum strains on productive and technological traits of sugar beet, as well as on the total number of microorganisms and azotobacter in rhizosphere. The results of this two-year study showed that effectiveness of the tested inoculation methods in increasing root yield and sugar content varies greatly, depending on year and azotobacter strains. Effectiveness of inoculation methods was not largely impacted by year on granulated sugar. Achieved granulated sugar yield was significantly higher by using pre-sowing azotobacter application, than by using seed inoculation. A significantly increased number of microorganisms in sugar beet rhizosphere was determined, not only by using pre-sowing azotobacter application but also by using sugar beet seed inoculation. Pre-sowing azotobacter application and inter-row cultivation both caused an equal increase in the number of these bacteria in sugar beet rhizosphere (42.2% and 46.9%. Use of sugar beet seed inoculation caused an increase of 33.7% in the number of azotobacter. In order to achieve higher effectiveness in applying azotobacter on productive and technological traits of sugar beet, and considering determined interaction between a certain year, an inoculation method and a strain, it is necessary for future research to focus on determining efficiency of these strains when they are in a mixture.

    The main aim of this study is to evaluate whether the potential transformation of the existing sugar plants of Northern Greece to modern bioethanol plants, using the existing cultivations of sugar beet, would be an environmentally sustainable decision. Using Life Cycle Inventory and Impact Assessment, all processes for bioethanol production from sugar beets were analyzed, quantitative data were collected and the environmental loads of the final product (bioethanol) and of each process were estimated. The final results of the environmental impact assessment are encouraging since bioethanol production gives better results than sugar production for the use of the same quantity of sugar beets. If the old sugar plants were transformed into modern bioethanol plants, the total reduction of the environmental load would be, at least, 32.6% and a reduction of more than 2 tons of CO{sub 2}e/sugar beet of ha cultivation could be reached. Moreover bioethanol production was compared to conventional fuel (gasoline), as well as to other types of biofuels (biodiesel from Greek cultivations). - Highlights: > Bioethanol production gives better results than sugar production from sugar beets. > In most cases, sugar beets, as an already industrialized plant has organizational virtues. > Bioethanol could be a sustainable independent way of energy production, alternative to biodiesel.

    2017-08-01

    Full Text Available Large amounts of waste biomass are generated in sugar factories from the processing of sugar beets. After diffusion with hot water to draw the sugar from the beet pieces, a wet material remains called pulp. In this study, waste sugar beet pulp biomass was enzymatically depolymerized, and the obtained hydrolyzates were subjected to fermentation processes. Bioethanol, biomethane, and biohydrogen were produced directly from the substrate or in combined mode. Stillage, a distillery by-product, was used as a feedstock for anaerobic digestion. During biosynthesis of ethanol, most of the carbohydrates released from the sugar beet pulp were utilized by a co-culture of Saccharomyces cerevisiae Ethanol Red, and Scheffersomyces stipitis LOCK0047 giving 12.6 g/L of ethanol. Stillage containing unfermented sugars (mainly arabinose, galactose and raffinose was found to be a good substrate for methane production (444 dm3 CH4/kg volatile solids (VS. Better results were achieved with this medium than with enzymatic saccharified biomass. Thermal pre-treatment and adjusting the pH of the inoculum resulted in higher hydrogen production. The largest (p < 0.05 hydrogen yield (252 dm3 H2/kg VS was achieved with sugar beet stillage (SBS. In contrast, without pre-treatment the same medium yielded 35 dm3 H2/kg VS. However, dark fermentation of biohydrogen was more efficient when sugar beet pulp hydrolyzate was used.

    2010-01-01

    Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases. Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed. Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration of 10 to 14 days if no systemic complications are present. In a developing country where the cost of managing complications of pancreatitis can be a limiting factor for patients, the use of prophylactic antibiotics early on in the disease in selected cases can be beneficial.

    2009-08-01

    A 67-year-old woman with insuline-dependent diabetes mellitus and chronic alcohol abuse was admitted with impaired consciousness and fever. Physical examination showed a livid induration of the perineal and vaginal soft tissues with crepitations. Laboratory tests showed greatly elevated infection parameters. Abdominal computed tomography revealed perineal and vaginal subcutaneous gas accumulation extending into the ventral abdominal wall. The combination of an obscure infection and subcutaneous genital gas accumulation suggested the diagnosis of Fournier gangrene, a necrotizing fasciitis. In spite of administration of broad-spectrum antibiotics and repeated surgical removal of necrotic tissue the patient died of multiple organ failure. Successful treatment of Fournier gangrene critically depends on immediate treatment. Administration of broad-spectrum antibiotics and aggressive surgical resection of the necrotic tissue may prevent continuing spreading of the infection. Computed tomography provides an early diagnosis and guides the presurgical evaluation of the subcutaneous spread. Georg Thieme Verlag KG Stuttgart * New York.

Therefore the harvest of the sugar beet tops (including leaves can be considered as current task for the sugar beet growing system. Modern technologies involve harvest of the tops of sugar beet in two stages: flat basic cut and collecting of the entire green mass at higher altitude and the subsequent cutting of the heads of root crops from the residues. Therefore, topical issues of the sensing of the heads of sugar beet roots arranged in rows, are related to the majority of the sugar beet toppers, cleaners of the sugar beet heads, leaves cutters and, digging up working bodies of some designs. The aim of this study is theoretical determination the optimum design and kinematic parameters of a new sensing mechanism of the sugar beet heads located in the soil on the basis of the theory of interaction of flat passive swath board sensing organ with the sugar beet heads during their topping when located in the soil. In the study there are used methods of creation of mathematical models of functioning of the agricultural machines and their working bodies with the using of main provisions of mathematics, theoretical mechanics, programming and numerical calculations on the PC. In this paper, there is presented a theoretical study of the interaction of passive sensing organ with the head of the sugar beet root when there are located residues of the leaves on a root head spherical surface in the form of short elastic rods. Thus, for such an interaction of the sensing organ and the head of sugar beet root head there is taken into account elastic-damping properties of the sugar beet leaves residues. In the study there was first of all developed a new design of the topper for sugar beet heads with the use of a flat swath board sensing organ, there was developed the equivalent scheme of the interaction of the

    Abstract Background With a cultivation area of 1.75 Mio ha and sugar yield of 16.7 Mio tons in 2006, sugar beet is a crop of great economic importance in Europe. The productivity of sugar beet is determined significantly by seed vigour and field emergence potential; however, little is known about the molecular mechanisms underlying these traits. Both traits exhibit large variations within sugar beet germplasm that have been difficult to ascribe to either environmental or genetic causes. Among...

    Some 15 per cent of all patients with acute pancreatitis develop necrotizing pancreatitis, with potentially significant consequences for both patients and healthcare services. This review summarizes the latest insights into the surgical and medical management of necrotizing pancreatitis. General management strategies for the treatment of complications are discussed in relation to the stage of the disease. Frequent clinical evaluation of the patient's condition remains paramount in the first 24-72 h of the disease. Liberal goal-directed fluid resuscitation and early enteral nutrition should be provided. Urgent endoscopic retrograde cholangiopancreatography is indicated when cholangitis is suspected, but it is unclear whether this is appropriate in patients with predicted severe biliary pancreatitis without cholangitis. Antibiotic prophylaxis does not prevent infection of necrosis and antibiotics are not indicated as part of initial management. Bacteriologically confirmed infections should receive targeted antibiotics. With the more conservative approach to necrotizing pancreatitis currently advocated, fine-needle aspiration culture of pancreatic or extrapancreatic necrosis will less often lead to a change in management and is therefore indicated less frequently. Optimal treatment of infected necrotizing pancreatitis consists of a staged multidisciplinary 'step-up' approach. The initial step is drainage, either percutaneous or transluminal, followed by surgical or endoscopic transluminal debridement only if needed. Debridement is delayed until the acute necrotic collection has become 'walled-off'. Outcome following necrotizing pancreatitis has improved substantially in recent years as a result of a shift from early surgical debridement to a staged, minimally invasive, multidisciplinary, step-up approach. © 2013 BJS Society Ltd.

    This article is based on the retrospective study of 4 cases of necrotic fasciitis of the upper extremity, in adult patients with a mean age of 57 years (range: 36 to 78 years) and with a male predominance (3 M/1 F). Presenting signs were variable: pain, febrile and inflammatory oedema, ecchymoses with inflammatory masses containing clear or haemorrhagic fluid. Treatment with antibiotics and anti-inflammatory drugs did not prevent progression to painless, necrotic ulcers. Rapid medical and surgical treatment constitutes an element essential of the prognosis and must include wide large debridement, antibiotics and intensive care.

    Full Text Available Cutaneous infections caused by Mycobacterium marinum have been attributed to aquarium or fish exposure after a break in the skin barrier. In most instances, the upper limbs and fingers account for a majority of the infection sites. While previous cases of necrotizing soft tissue infections related to M. marinum have been documented, the importance of our presenting case is to illustrate the aggressive nature of M. marinum resulting in a persistent necrotizing soft tissue infection of a finger that required multiple aggressive wound debridements, followed by an amputation of the affected extremity, in order to hasten recovery.

    Full Text Available Omphalitis is an infrequent neonatal infection of the umbilicus. Necrotizing infections are a rare complication of omphalitis that requires prompt antibiotic therapy, surgical debridement, and supportive care. Here, we present a rare case of Clostridium sordellii necrotizing omphalitis that progressed to severe toxemia characterized by refractory hypotension, massive capillary leak, leukemoid reaction, and absence of fever. These clinical features are common in C. sordellii infections and harbor a poor prognosis with only one reported survivor (out of 12 of C. sordellii omphalitis reported in the literature. Early antibiotic and surgical intervention remain the mainstay of care as no early detection assays or antitoxins are commercially available.

    Full Text Available Mucormycosis caused by Apophysomyces variabilis is rarely reported in humans. A case of A. variabilis infection in an immunocompetent men after friction burns in a car accident is described. The infection presented as a rapidly progressive necrotizing infection of the skin and soft tissue, which required extensive surgical debridement and total colonic defunctioning colostomy associated with prolonged antifungal therapy. A. variabilis infection should be considered as a differential diagnosis of rapidly progressive necrotizing skin and soft tissue infections in immunocompetent individuals.

    2016-01-01

    Full Text Available Necrotizing sialometaplasia is a rare benign and self-limiting disease, which commonly affects the minor salivary glands. Typically, it involves the seromucinous glands located at palate, buccal mucosa, tongue, tonsil, nasal cavity, trachea, larynx, maxillary sinus, and retromolar trigone. We report two such cases of necrotizing sialometaplasia to create awareness among the pathologists and surgeons because of its close morphological and clinical resemblance to squamous cell carcinoma. We have also documented that, the ischemic necrosis of salivary gland is the result of a vasculitic process.

    We analyzed a metagenome of the bacterial community associated with the taproot of sugar beet (Beta vulgaris L.) in order to investigate the genes involved in plant growth-promoting traits (PGPTs), namely 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase, indole acetic acid (IAA), N2 fixation, phosphate solubilization, pyrroloquinoline quinone, siderophores, and plant disease suppression as well as methanol, sucrose, and betaine utilization. The most frequently detected gene among the PGPT categories encoded β-1,3-glucanase (18 per 105 reads), which plays a role in the suppression of plant diseases. Genes involved in phosphate solubilization (e.g., for quinoprotein glucose dehydrogenase), methanol utilization (e.g., for methanol dehydrogenase), siderophore production (e.g. isochorismate pyruvate lyase), and ACC deaminase were also abundant. These results suggested that such PGPTs are crucially involved in supporting the growth of sugar beet. In contrast, genes for IAA production (iaaM and ipdC) were less abundant (~1 per 105 reads). N2 fixation genes (nifHDK) were not detected; bacterial N2 -fixing activity was not observed in the 15N2 -feeding experiment. An analysis of nitrogen metabolism suggested that the sugar beet microbiome mainly utilized ammonium and nitroalkane as nitrogen sources. Thus, N2 fixation and IAA production did not appear to contribute to sugar beet growth. Taxonomic assignment of this metagenome revealed the high abundance of Mesorhizobium, Bradyrhizobium, and Streptomyces, suggesting that these genera have ecologically important roles in the taproot of sugar beet. Bradyrhizobium-assigned reads in particular were found in almost all categories of dominant PGPTs with high abundance. The present study revealed the characteristic functional genes in the taproot-associated microbiome of sugar beet, and suggest the opportunity to select sugar beet growth-promoting bacteria.

    This study reveals for the first time a major QTL for post-winter bolting resistance in sugar beet ( Beta vulgaris L.). The knowledge of this QTL is a major contribution towards the development of a winter sugar beet with controlled bolting behavior. In cool temperate climates, sugar beets are currently grown as a spring crop. They are sown in spring and harvested in autumn. Growing sugar beet as a winter crop with an extended vegetation period fails due to bolting after winter. Bolting after winter might be controlled by accumulating genes for post-winter bolting resistance. Previously, we had observed in field experiments a low post-winter bolting rate of 0.5 for sugar beet accession BETA 1773. This accession was crossed with a biennial sugar beet with regular bolting behavior to develop a F3 mapping population. The population was grown in the greenhouse, exposed to artificial cold treatment for 16 weeks and transplanted to the field. Bolting was recorded twice a week from May until October. Post-winter bolting behavior was assessed by two different factors, bolting delay (determined as days to bolt after cold treatment) and post-winter bolting resistance (bolting rate after winter). For days to bolt, means of F3 families ranged from 25 to 164 days while for bolting rate F3 families ranged from 0 to 1. For each factor one QTL explaining about 65% of the phenotypic variation was mapped to the same region on linkage group 9 with a partially recessive allele increasing bolting delay and post-winter bolting resistance. The results are discussed in relation to the potential use of marker-assisted breeding of winter sugar beets with controlled bolting.

    The treatment of sugar beet processing wastewater in aerobic granular sequencing batch reactor (SBR) was examined in terms of chemical oxygen demand (COD) and nitrogen removal efficiency. The effect of sugar beet processing wastewater of high solid content, namely 2255 ± 250 mg/L total suspended solids (TSS), on granular sludge was also investigated. Aerobic granular SBR initially operated with the effluent of anaerobic digester treating sugar beet processing wastewater (Part I) achieved average removal efficiencies of 71 ± 30% total COD (tCOD), 90 ± 3% total ammonifiable nitrogen (TAN), 76 ± 24% soluble COD (sCOD) and 29 ± 4% of TSS. SBR was further operated with sugar beet processing wastewater (Part II), where the tCOD, TAN, sCOD and TSS removal efficiencies were 65 ± 5%, 61 ± 4%, 87 ± 1% and 58 ± 10%, respectively. This study indicated the applicability of aerobic granular SBRs for the treatment of both sugar beet processing wastewater and anaerobically digested processing wastewater. For higher solids removal, further treatment such as a sedimentation tank is required following the aerobic granular systems treating solid-rich wastewaters such as sugar beet processing wastewater. It was also revealed that the application of raw sugar beet processing wastewater slightly changed the aerobic granular sludge properties such as size, structure, colour, settleability and extracellular polymeric substance content, without any drastic and negative effect on treatment performance.

    Full Text Available Summary. Different methods of obtaining the product given were tested and rational modes for the proposed technology were chosen in the development of technology for production of sugar beet concentrated juice. The sugar beet concentrated juice is obtained as follows: sugar beets are washed in the continuous action washing machine, checked, rotten or spoiled beets are removed from the cycle, and insufficiently treated roots are directed to re-washing. Then with the help of thermal processing the sugar beet is peeled. The peeled roots are white. They are crushed to the 3-4 mm particles size, mixed with acidified to pH 3,5-4,0 water (hydromodule 1-1.2, then the resulting mass is heated to 80 0C temperature. The use of acidified water is necessary to prevent the darkening initiation. Then the received sugar beet mass is fed to pressing to obtain its juice. The pressed juice depending on the beet source contains 12 % of DS and 1.5-3 % reducing substances (RS of the total mass of dry substances. The juice concentration is under the suction of 0.008 MPa at the boiling temperature of up to 60 0C to the content of 70 % DS. Due to the delicate mode, the sugars breakdown is less intensive, the finished product is of good quality. At the simultaneous concentration with steam the volatile substances with a specific smell are removed, that improves the juice taste and smell. Under this mode, the sugar hydrolysis is intensive, there is a growth reducing substances up to 20 %, the color is increased to 40% density. The research results allow to recommend the product obtained as the sugar syrup substitute.

    Necrotizing fasciitis is an orthopedic emergency. The ability to quickly and accurately diagnose this rapidly spreading disease can save a patient's life and limb. However, the diagnosis is complex because necrotizing fasciitis usually manifests as a less severe cellulitis or abscess while the majority of the damages rage beneath the surface of the skin. Although the diagnosis is not new, the potential causes and vectors continually change. This article reports a new source of necrotizing fasciitis in an intramuscular injection of "bath salts," a rapidly emerging street drug that is legal in some states and evades authorities with its innocuous name. The patient presented 2 days after injection of bath salts with extensive cellulitis extending to the mid portion of her upper arm. The cellulitis initially responded to broad-spectrum intravenous antibiotics, but rapidly deteriorated 48 hours later, leading to a forequarter amputation with radical mastectomy and chest wall debridement to obtain healthy tissue margins and control the disease. The patient made a full recovery after further minor debridements, negative pressure dressings, directed antibiotic therapy, and skin grafting. The recent emerging popularity of this highly obtainable, injectable substance may lead to an increase in cases of necrotizing fasciitis. Orthopedic surgeons should be vigilant in diagnosing this process early and should perform an extensive debridement. Copyright 2012, SLACK Incorporated.

    New therapeutic approaches are urgently needed to improve survival outcomes for patients with necrotizing pneumonia caused by Staphylococcus aureus One such approach is adjunctive treatment with intravenous immunoglobulin (IVIG), but clinical practice guidelines offer conflicting recommendations. In a preclinical rabbit model, prophylaxis with IVIG conferred protection against necrotizing pneumonia caused by five different epidemic strains of community-associated methicillin-resistant S. aureus (MRSA) as well as a widespread strain of hospital-associated MRSA. Treatment with IVIG, either alone or in combination with vancomycin or linezolid, improved survival outcomes in this rabbit model. Two specific IVIG antibodies that neutralized the toxic effects of α-hemolysin (Hla) and Panton-Valentine leukocidin (PVL) conferred protection against necrotizing pneumonia in the rabbit model. This mechanism of action of IVIG was uncovered by analyzing loss-of-function mutant bacterial strains containing deletions in 17 genes encoding staphylococcal exotoxins, which revealed only Hla and PVL as having an impact on necrotizing pneumonia. These results demonstrate the potential clinical utility of IVIG in the treatment of severe pneumonia induced by S. aureus. Copyright © 2016, American Association for the Advancement of Science.

    Vitamin K antagonists are widely used in thromboembolic diseases. Hemorrhagic complications related to drug overdose represent their main side effect. We report a rare side effect, a severe and unexpected type of skin vasculitis - necrotic leg ulcer - induced by vitamin K antagonist. A 63-year-old female with a history of diabetes developed hyperalgesic necrotic ulcerations on the lower limbs one month after starting an acenocoumarol-based treatment for ischemic heart disease. Histological examination revealed lymphocytic vasculitis with fibrinoid necrosis. Etiological explorations searching for vasculitis were negative. In the absence of a precise etiology, drug-induced ulcer was suspected. Low molecular weight heparin was prescribed to replace acenocoumarol. The lesions slowly resolved with topical treatment. The chronological criteria and the negativity of etiological explorations allowed the diagnosis of vitamin K antagonist-induced necrotic skin ulcer. Clinicians should be aware of this rare complication induced by oral anticoagulants because of its practical therapeutic implications. This is the first case of necrotic leg ulcer induced by acenocoumarol corresponding histologically to necrotising lymphocytic vasculitis. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Both surgeons and dermatologists are increasingly challenged with the prompt diagnosis and management of severe soft tissue infections. Although early surgical intervention appears to be for life-saving in many patients, especially those diagnosed as necrotizing fasciitis, some patients recover well with only conservative treatment. Because most of these infections have similar initial clinical presentations, there remains a need to find reliable clinical and/or laboratory parameters that can predict the prognosis and to accordingly judge the necessity and timing of operation. We conducted a retrospective study of case records of patients with necrotizing soft tissue infections. The clinical presentation, laboratory findings, management, and therapeutic outcome of 34 cases with necrotizing soft tissue infections were reviewed. These infections were potentially life-threatening, with an overall mortality of 26.5%. Shock on admission was an extremely grave sign associated with a poor prognosis (P universal approach, regardless of classification, is essential for all suspected cases of necrotizing soft tissue infections. Prompt diagnostic studies are needed, and platelet counts, PT, and PTT are readily available parameters that provide substantial information on diagnosis and treatment, thus avoiding an unwarranted loss of life or unnecessary operative sequelae. Early diagnosis and, in most cases, prompt radical surgical, intervention remain the cornerstone of successful management in these infections.

    Full Text Available Abstract Introduction Necrotizing fasciitis in neonates is rare and is associated with almost 50% mortality. Although more than 80 cases of neonates (under one month of age with necrotizing fasciitis have been reported in the literature, only six of them are identified as originating in the scrotum. Case presentation We report the case of a four-week-old, full-term, otherwise-healthy Caucasian baby boy who presented with an ulcerating lesion of his scrotal wall. His scrotum was explored because of a provisional diagnosis of missed torsion of the testis. He was found to have necrotizing fasciitis of the scrotum. We were able to preserve the testis and excise the necrotic tissue, and with intravenous antibiotics there was a successful outcome. Conclusions Fournier gangrene is rarely considered as part of the differential diagnosis in the clinical management of the acute scrotum. However, all doctors who care for small babies must be aware of this serious condition and, if it is suspected, should not hesitate in referring the babies to a specialist pediatric surgical center immediately.

    The objective of this study was to investigate the effect of feed restriction on the intestinal ecosystem and on the pathogenesis of experimental necrotic enteritis in broiler chicks. To induce subclinical necrotic enteritis, an experimental challenge model using a specific diet formulation, Gumboro vaccination, oral inoculation of broilers with a 10-fold dose of attenuated anticoccidial vaccine and multiple oral inoculations with a specific strain of Clostridium perfringens was adopted. Two hundred and forty 1-day-old Cobb 500 broilers were randomly allocated to four groups: feed restricted, challenged, both feed restricted and challenged, and negative control. At 21, 22, 23 and 24 days of age, the intestines, gizzard and liver were collected from 15 birds in each group and scored for gross lesions. The intestinal digesta was collected for pH and viscosity determination. One caecum from each bird was taken for microbiological analysis. The application of feed restriction in birds challenged with C. perfringens reduced the necrotic enteritis lesion score significantly (P ≤ 0.05) and feed restriction significantly reduced (P ≤ 0.05) pH in the small intestine, the viscosity of the jejunum digesta as well as the C. perfringens counts in the caeca compared with the controls. In conclusion, feed restriction of broilers has a positive effect on the intestinal ecosystem and a significant protective effect against necrotic enteritis in the subclinical experimental model.

  12. Report a possible correlation between necrotizing ulcerative gingivitis and mononucleosis

    Rosa Francinne Miranda

    2011-12-01

    Full Text Available Necrotizing ulcerative gingivitis is a relatively uncommon periodontal disease, characterized by ulceration, necrosis, pain and gingival bleeding. Factors often related to its occurrence include stress and systemic viral infections, such as those caused by cytomegalovirus and Epstein-Barr virus type 1, the latter being also considered the causative agent of infectious mononucleosis. This article aims to describe a clinical case of a female patient who presented with necrotizing ulcerative gingivitis associated with a clinical picture of infectious mononucleosis, as well as to review the literature concerning a possible correlation between these pathologies. This patient presented to our health care facility with necrotizing ulcerative gingivitis accompanied by lymphadenopathy, fever and prostration, after laboratory tests, Epstein-Barr virus type 1 infection was confirmed, as well as the co-occurrence of pathologies: necrotizing ulcerative gingivitis and infectious mononucleosis. Symptom remission in both disorders also occurred concomitantly, after instruction in plaque control measures and palliative medication for control of systemic symptoms. Therefore, although there is no scientific validation of an association between these two pathologies, it is imperative that all diagnostic alternatives be considered and investigated, in order to establish the therapeutic approach most appropriate to the patient.

    Necrotizing fasciitis in neonates is rare and is associated with almost 50% mortality. Although more than 80 cases of neonates (under one month of age) with necrotizing fasciitis have been reported in the literature, only six of them are identified as originating in the scrotum. We report the case of a four-week-old, full-term, otherwise-healthy Caucasian baby boy who presented with an ulcerating lesion of his scrotal wall. His scrotum was explored because of a provisional diagnosis of missed torsion of the testis. He was found to have necrotizing fasciitis of the scrotum. We were able to preserve the testis and excise the necrotic tissue, and with intravenous antibiotics there was a successful outcome. Fournier gangrene is rarely considered as part of the differential diagnosis in the clinical management of the acute scrotum. However, all doctors who care for small babies must be aware of this serious condition and, if it is suspected, should not hesitate in referring the babies to a specialist pediatric surgical center immediately.

    2011-01-01

    This study examines the financial feasibility of producing ethanol biofuel from sugar beets in central North Dakota. Under the Energy Independence and Security Act (EISA) of 2007, biofuel from sugar beets uniquely qualifies as an 'advanced biofuel'. EISA mandates production of 21 billion gallons of advanced biofuels annually by 2022. A stochastic simulation financial model was calibrated with irrigated sugar beet data from central North Dakota to determine economic feasibility and risks of production for 0.038 hm 3 y -1 (or 10 MGY (Million Gallon per Year) and 0.076 hm 3 y -1 (or 20 MGY) ethanol plants. Study results indicate that feedstock costs, which include sugar beets and beet molasses, account for more than 70 percent of total production expenses. The estimated breakeven ethanol price for the 0.076 hm 3 y -1 plant is $400 m -3 ($1.52 per gallon) and $450 m -3 ($1.71 per gallon) for the 0.038 hm 3 y -1 plant. Breakeven prices for feedstocks are also estimated and show that the 0.076 hm 3 y -1 plant can tolerate greater ethanol and feedstock price risks than the 0.038 hm 3 y -1 plant. Our results also show that one of the most important factors that affect investment success is the price of ethanol. At an ethanol price of $484.21 m -3 ($1.84 per gallon), and assuming other factors remain unchanged, the estimated net present value (NPV) for the 0.076 hm 3 y -1 plant is $41.54 million. By comparison, the estimated NPV for the 0.038 hm 3 y -1 plant is only $8.30 million. Other factors such as changes in prices of co-products and utilities have a relatively minor effect on investment viability. -- Highlights: → Sugar beets and beet molasses costs account for more than 70 percent of total production expenses. → The estimated breakeven ethanol prices for the 0.076 hm 3 y -1 and 0.038 hm 3 y -1 ethanol plants are $400 m -3 and $450 m -3 respectively. → The price of ethanol will be one of the most important factors for determining the future feasibility of a

    Full Text Available Effects of biological carbon (bio-char on sugar beet growth were studied by pot experiments simulating long residual herbicide residues in soil environment. The results showed that the safety threshold of sugar beet growth with clomazone residual was 0.12 mg·kg-1, and beyond this value, sugar beet growth was in inhibition with clomazone residues increased gradually; Early seedling growth under severe phytotoxicity inhibition rate reached 100% when clomazone concentration was greater than 0.48 mg·kg-1; Seedlings subjected to injury sym-ptoms generally reduced to no phytotoxicity after put into a certain amount of bio-car in soil, the plant growth and root shoot ratio increased. Sugar beet root tuber yield and total sugar yield were influenced after applying carbon, sugar content increased 1.10%, which showed significant difference compared with CK. It explained that the bio-char could promote the growth of sugar beet. Applying biochar to soil could reduce the biological hazardous taken by clomazone residues within certain scope.

    This study was planned to utilize sugar beet powder as a rich source of dietary fibre in cookies. Purposely, five treatments namely T1, T2, T3, T4 and T5 with 4%, 8%, 12%, 16% and 20% sugar beet powder addition in wheat flour were chosen to estimate fibre, antioxidant profiling and engineering properties of cookies. Results showed an increased content of all above mentioned parameters. With the increment in sugar beet powder addition in treatments, dietary fibre analysis have shown that total dietary fibre (TDF), insoluble dietary fibre (IDF) and soluble dietary fibre (SDF) have depicted increasing trend with maximum for T5 for all dietary fibre types. Significant results were obtained for in vitro antioxidant studies including total phenolic content (TPC) and DPPH that showed increasing trend with T1 0.6 mg GAE/g and maximum values for T5 with 2.0 mg GAE/g for TPC and for DPPH with T5 being maximum value of 1.7% and minimum for T1 with 1.3%. T5 treatment with 20% sugar beet gave best physicochemical results but disturbed sensory properties while T3 with 12% sugar beet powder showed good physicochemical and sensory characteristics. Therefore, T3 with 12% level is considered as the best source of dietary fibre in bakery products and can be considered as the prospective choice to address metabolic syndromes. (author)

    Full Text Available Sugar beet pulp, a byproduct of sugar beet processing, can be used as a feedstock in second-generation ethanol production. The objective of this study was to investigate the effects of pretreatment, of the dosage of cellulase and hemicellulase enzyme preparations used, and of aeration on the release of fermentable sugars and ethanol yield during simultaneous saccharification and fermentation (SSF of sugar beet pulp-based worts. Pressure-thermal pretreatment was applied to sugar beet pulp suspended in 2% w/w sulphuric acid solution at a ratio providing 12% dry matter. Enzymatic hydrolysis was conducted using Viscozyme and Ultraflo Max (Novozymes enzyme preparations (0.015–0.02 mL/g dry matter. Two yeast strains were used for fermentation: Ethanol Red (S. cerevisiae (1 g/L and Pichia stipitis (0.5 g/L, applied sequentially. The results show that efficient simultaneous saccharification and fermentation of sugar beet pulp was achieved. A 6 h interval for enzymatic activation between the application of enzyme preparations and inoculation with Ethanol Red further improved the fermentation performance, with the highest ethanol concentration reaching 26.9±1.2 g/L and 86.5±2.1% fermentation efficiency relative to the theoretical yield.

    Very little is known about the physiological interactions between plants and endophytic bacteria. We investigated the impact of three endophytic bacteria, Bacillus pumilus 2-1, Chryseobacterium indologene 2-2, and Acinetobacter johnsonii 3-1, on the photosynthetic capacity and growth of sugar beet. Endophyte-free plants were obtained first and infected with the bacteria. Measurements of total chlorophyll content revealed very significant differences between endophyte-free beet plants and some infected by endophytic bacteria. The maximum photochemical yield (Fv/Fm) was used to determine any photosynthetic effect on plants caused by biotic or abiotic factors. After 30 days of growth, there was significantly higher Fv/Fm for endophyte-infected than endophyte-free plants. The light response curves of beet showed that photosynthetic capacity was significantly increased in endophyte-infected plants. Photosynthesis of endophyte-free plants was saturated at 1,300 micromol m(-2) s(-1), whereas endophyte-infected plants were not saturated at the irradiance used. The effect seemed to be due to promotion of electron transport in the thylakoid membranes. Promotion of photosynthetic capacity in sugar beet was due to increased chlorophyll content, leading to a consequent increased carbohydrate synthesis. It is possible that the increased maximum yield of photosynthesis in sugar beet was promoted by phytohormones and produced by the bacteria.

    Full Text Available Sugar beet (Beta vulgaris L. - one of the most important crop in the world. In Kazakhstan, it is a traditional and major source of domestic sugar. The industry of cultivation and production of sugar beet is one of the priority areas of agricultural development of the country. In this paper, we studied the regeneration ability of different genotypes of sugar beet explants on selective media with the culture filtrate of the pathogen fungus F. oxysporum var. orthoceras. From the roots and shoots of sugar beet the pathogen Fusarium root rot was isolated. Was obtained pure cultures of the isolated pathogen. As a result, of morphological and cultural descriptions, as well as microbiological analysis it was revealed that the isolated pathogen is Fusarium Oxysporum. The results showed the pathogenicity of the fungus. For regeneration in vitro of the sugar beet genotypes resistant to the pathogen the culture media was optimized to the culture filtrate of the fungus F. oxysporum var. orthoceras. The frequency of shoot regeneration, depending on the genotype, was 1,0-12,5 %. On these explants the multiple shoot formations were observed.

    Full Text Available The additive of acceptable sensory, physical and chemical and microbiological characteristics was made from cossettes. Great water binding capacity related to microcrystals of cellulose qualifies this additive as a desired one in bread making process. Bread was baked in the laboratory and patent flour was used. The additive with particles smaller than 95 (m was supplemented in the quantities of 2, 5 and 10%. The data related to the influence of the quantity of additive on white bread quality point that parallel to increasing the amount of the additive in the dough, yield of dough and bread were also increased. Negative effects are detected as volume depression and inferior bread crumb quality and altered crumb color. The decrease in bread quality is small if 2% of additive was applied, but significant with 5 and 10%. The bread freshness was highly graded 48 hours after baking due to the ability of the additive to retain water. On the whole, bread of superior quality supplemented by 5 and 10% of the additive from sugar beet fiber can be easily made by fortifying flour with gluten and by adding appropriate dough conditioner.

  8. Phloem unloading in developing leaves of sugar beet

    Physiological and transport data support a symplastic pathway for phloem unloading in developing leaves of sugar beet (Beta vulgaris L. Klein E, multigerm). The sulfhydryl inhibitor parachloromercuribenzene sulfonic acid (PCMBS) inhibited uptake of [ 14 C]-sucrose added to the free space of developing leaves, but did not affect import of [ 14 C]-sucrose during steady-state 14 CO 2 labeling of a source leaf. The passively-transported xenobiotic sugar, [ 14 C]-L-glucose did not readily enter mesophyll cells when supplied through the cut end of the petiole of a sink leaf as determined by whole leaf autoradiography. In contrast, [ 14 C]-L-glucose translocated through the phloem from a mature leaf, rapidly entered mesophyll cells, and was evenly distributed between mesophyll and veins. Autoradiographs of developing leaves following a pulse of 14 CO 2 to a source leaf revealed rapid passage of phloem translocated into progressively higher order veins as the leaf developed. Entry into V order veins occurred during the last stage of import through the phloem. Import into developing leaves was inhibited by glyphosate (N-phosphomethylglycine), a herbicide which inhibits the aromatic amino acid pathway and hence protein synthesis. Glyphosate also stopped net starch accumulation in sprayed mature leaves, but did not affect export of carbon from treated leaves during the time period that import into developed leaves was inhibited

    Chloroplasts contain 80-90% of iron taken up by plant cells. Though some iron transport-related envelope proteins were identified recently, the mechanism of iron uptake into chloroplasts remained unresolved. To shed more light on the process of chloroplast iron uptake, trials were performed with isolated intact chloroplasts of sugar beet (Beta vulgaris). Iron uptake was followed by measuring the iron content of chloroplasts in the form of ferrous-bathophenantroline-disulphonate complex after solubilising the chloroplasts in reducing environment. Ferric citrate was preferred to ferrous citrate as substrate for chloroplasts. Strong dependency of ferric citrate uptake on photosynthetic electron transport activity suggests that ferric chelate reductase uses NADPH, and is localised in the inner envelope membrane. The K(m) for iron uptake from ferric-citrate pool was 14.65 ± 3.13 μM Fe((III))-citrate. The relatively fast incorporation of (57)Fe isotope into Fe-S clusters/heme, detected by Mössbauer spectroscopy, showed the efficiency of the biosynthetic machinery of these cofactors in isolated chloroplasts. The negative correlation between the chloroplast iron concentration and the rate of iron uptake refers to a strong feedback regulation of the uptake. Copyright © 2011 Elsevier Masson SAS.

    Cane molasses, most of which is imported, is used as a raw material for production of baker's yeast (Saccharomyces cerevisiae) in Japan. On the other hand, beet molasses is scarcely used for this purpose, but it can be of great advantage to cane molasses because it is domestically produced in relatively high amounts as a by-product of beet sugar processing. However, the yield of baker's yeast is sometimes low with Japanese beet molasses compared to imported cane molasses. For the production of baker's yeast with Japanese beet molasses, we evaluated S. cerevisiae strains, including industrial and laboratory strains, to group them according to the growth profile on beet and cane molasses. To discuss the factors affecting growth, we further analyzed the major compounds in both types of molasses. Beet molasses seems to contain compounds that promote the growth of beet molasses-favoring strains rather than inhibit the growth of cane molasses-favoring strains. It was assumed that α-amino acid was one of the growth promotion factors for beet molasses-favoring strains. Copyright © 2013 The Society for Biotechnology, Japan. Published by Elsevier B.V.

    Full Text Available Sugar beet hybrids are considered as a factor of intensification of the beet-sugar branch. At the modern stage of development of agriculture under condition of reduction of sugar beet sown area, shortage of material - technical resources which influence the formation of productivity of sugar beet as a crop of intensive type, hybrids must have a high genetically conditioned biological potential of productive ability, resistance to pests and diseases, abiotic stress factors, must have broad adaptive abilities. Analysis of the modern sugar beet hybrids included bately in the state Register of plant varieties of Ukraine is presented. Transfer of the branch to the intensive way of development is possible only under conditions of a complex approach to solving this problem.

    Full Text Available This study was conducted to identify the optimal method of sugar beet (Beta vulgaris var. saccharifera seed sterilization to "in vitro" cultures initiation, and to found a cultivar that is suitable to growth in specific conditions of vitroculture. The study was necessary because the literature does not refer to the method of initiating vitrocultures from encapsulated beet seeds and to avoid any losses that may occur in a massive micropropagation. The most optimal method for beet encapsulated seeds asepsization, prior inoculation on the vitroculture medium consists in the their dipping in sodium hypochlorite solution for 15 minutes, and the best cultivar which was suited to micropropagation was Evelina, but Diamant too, with 90 - 95% germination rate and a very good ulterior growth.

    2009-04-01

    Beet powdery mildew incited by Erysiphe betae is a serious foliar fungal disease of worldwide distribution causing losses of up to 30%. In the present work, we searched for resistance in a germplasm collection of 184 genotypes of Beta vulgaris including fodder (51 genotypes), garden (60 genotypes), leaf (51 genotypes), and sugar (22 genotypes) beet types. Resistant genotypes were identified in the four beet types under study. In addition, mechanisms underlying resistance were dissected through histological studies. These revealed different resistance mechanisms acting at different fungal developmental stages, i.e., penetration resistance, early and late cell death, or posthaustorial resistance. Most genotypes were able to hamper fungal development at several stages. The later are interesting for breeding aiming to resistance durability. Furthermore, characterization of defense mechanisms will be useful for further cellular and molecular studies to unravel the bases of resistance in this species.

    Resistance gene analogs (RGAs) were searched bioinformatically in the sugar beet (Beta vulgaris L.) genome as potential candidates for improving resistance against different diseases. In the present study, Ion Torrent sequencing technology was used to identify mutations in 21 RGAs. The DNA samples of ninety-six individuals from six sea beets (Beta vulgaris L. subsp. maritima) and six sugar beet pollinators (eight individuals each) were used for the discovery of single-nucleotide polymorphisms (SNPs). Target amplicons of about 200 bp in length were designed with the Ion AmpliSeq Designer system in order to cover the DNA sequences of the RGAs. The number of SNPs ranged from 0 in four individuals to 278 in the pollinator R740 (which is resistant to rhizomania infection). Among different groups of beets, cytoplasmic male sterile lines had the highest number of SNPs (132) whereas the lowest number of SNPs belonged to O-types (95). The principal coordinates analysis (PCoA) showed that the polymorphisms inside the gene Bv8_184910_pkon (including the CCCTCC sequence) can effectively differentiate wild from cultivated beets, pointing at a possible mutation associated to rhizomania resistance that originated directly from cultivated beets. This is unlike other resistance sources that are introgressed from wild beets. This gene belongs to the receptor-like kinase (RLK) class of RGAs, and is associated to a hypothetical protein. In conclusion, this first report of using Ion Torrent sequencing technology in beet germplasm suggests that the identified sequence CCCTCC can be used in marker-assisted programs to differentiate wild from domestic beets and to identify other unknown disease resistance genes in beet.

    Full Text Available The sugar beet weevil, Lixus incanescens B., is one of the most important pests of sugar beet plant in Iran. The petioles and leaves of sugar beet are attacked by larvae and adults of the sugar beet weevil. Chemical application is currently used for controlling the pest. Digestion in the alimentary canal of the sugar beet weevil is facilitated by some carbohydrases. Results of the in vitro studies indicated the presence of alpha-amylase, beta-glucosidase and beta-galactosidase in the digestive tract of the pest. Highest activities of alpha-amylase, beta-glucosidase and beta-galactosidase were at pH 5, pH 5 and pH 4, respectively. No significant alpha-glucosidase and alpha-galactosidase activity was detected in the pest's digestive system. Optimum temperatures for alpha-amylase, beta-glucosidase and beta-galactosidase activity were determined at 45, 50 and 40 oC, respectively. alpha-amylase was more stable under acidic condition (pH 4 to pH 6 than under highly acidic and alkaline condition. Na+ and K+ increased alpha-amylase activity, but sodium dodecyl sulfate significantly decreased amylase activity. Also, the activity of alpha-amylase was inhibited by the other compounds such as MgCl2, CaCl2 and EDTA. Zymogram analysis using native-PAGE revealed one band of alpha-amylase activity in Lixus incanescens. High activity of carbohydrases in the digestive system of adults was determined and further researches are needed to be applied to design new strategies for controlling the sugar beet weevil based on natural carbohydrase inhibitors.

    External arbuscular mycorrhiza (AM) mycelium plays an important role in soil while interacting with a range of biotic and abiotic factors. One example is the soil organic amendment sugar beet waste. The fermented Aspergillus niger–sugar beet waste (ASB) increases growth and P uptake by the AM...... mycelium in soil whereas non-fermented waste (SB) had a strong inhibitory effect. The underlying mechanisms are not understood. We used gas chromatography–mass spectrometry to identify differences in composition of water extracts of ASB and SB. The chromatograms showed that ferulic acid was present in SB...

    Emissions of greenhouse gases such as CO 2 , CO, CH 4 and NO X from fossil fuel use are implicated in climate change. The use of bioethanol is one means to reduce fossil fuel use and emissions of greenhouse gases. This study investigated research to produce ethanol from sugar beet and use as fuel in Turkey. The calculated demand for bioethanol amounted to some 220,000 m 3 where a 5% ethanol mix in petrol was used. Turkey has the potential to produce 30 million ton of sugar beet, which is sufficient to meet the bioethanol demand. (author)

    Full Text Available Necrotizing scleritis is an uncommon but potential disastrous infection to the eye. It is commonly caused by vaso-occlusive autoimmune diseases such as rheumatoid arthritis or surgically-induced, and rarely due to infections. In this article, we presented a rare case of necrotizing scleritis caused by herpes infection in an immunocompromised patient. A 49 years old, retroviral positive gentleman presented to our clinic with a painful, red right eye associated with watering, photophobia and blurring of vision. His right eye rapidly deteriorated leading to an impending perforation of the sclera despite intensive antimicrobial therapy. The patient was started on acyclovir ointment and subsequently improved remarkably salvaging the eye from the need of an evisceration. Although the visual prognosis was poor, structural integrity of the eye was achieved.

    Lemierre syndrome is characterized by a septic thrombophlebitis of the internal jugular vein (IJV) following an oropharyngeal infection. We report a case of Lemierre syndrome that occurred in a context of angina and necrotizing cellulitis of the neck in a 45-year-old patient. The Doppler ultrasound exam of the neck vessels and a neck CT showed an IJV thrombophlebitis. No germ could be isolated in the samples (blood culture, pus). The treatment associated antibiotics, heparin and surgical debridement of the necrotic tissues with extraction of the thrombus after ligation and section of the IJV. The postoperative course was uneventful. Lemierre syndrome is a rare but serious disease. Its low incidence makes him a forgotten disease. It should be systematically suspected in any oropharyngeal infection with the presence of a large painful swelling of the neck. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Severe acute pancreatitis is a potentially life-threatening disease. Pancreatic necrosis is associated with an aggravated prognosis, while superimposed infection is almost always lethal without surgery. Bacterial translocation mainly from the gut is the most widely accepted mechanism in the pathogenesis of infected pancreatic necrosis. Infected pancreatic necrosis should be suspected in the presence of the usual markers of systemic inflammation (i.e., fever and leukocytosis), organ failure, or a protracted severe clinical course. The diagnostic method of choice to confirm the diagnosis of pancreatic necrosis is contrast-enhanced computed tomography, where necrotic areas are evidenced as regions without enhancement. The presence of pancreatic necrotic infection should be based on a combination of clinical manifestations, results of laboratory investigation (mainly increased levels of CRP and / or procalcitonin), and can be confirmed by image-guided fine-needle aspiration and gram stain /culture of the aspirates. Surgery remains the treatment of choice for the management of infected pancreatic necrosis and involves open necrosectomy (debridement) and wide drainage of the peripancreatic areas, often in association with continuous irrigation. Planned reoperations may be required to achieve complete removal of the necrotic / infected material. The timing of surgery is of paramount importance; ideally, surgery should be performed after 2 or 3 weeks from the onset of pancreatitis. Recently, various minimally invasive approaches have been described, but they have not been compared in prospective trials with the classical open surgery. Antibiotic therapy is routinely used in patients with infected necrotizing pancreatitis, in conjunction with surgical debridement; its role, however, in the management of patients with sterile necrosis is recently questioned. Nutritional support should be taken into consideration in these patients; enteral nutrition should be preferred over

    Full Text Available Powdery mildew, caused by Erysiphe betae is a major foliar disease of sugar beet in areas with dry and relatively warm weather conditions throughout the world. In the present study, four fungicides belonging to the relatively new class of strobilurin fungicides, azoxystrobin, kresoxim-methyl pyraclostrobin and trifloxystrobin were evaluated in three different application doses (100, 150 and 200 mg a.i. ha–1 during 2003-2004 for the control of the disease. Among the four strobilurin fungicides tested trifloxystrobin and kresoxim-methyl were the most effective with control efficiency values higher than 94% compared to the control treatment even when applied at lower application dose of 100 mg a.i. ha–1. Azoxystrobin and pyraclostrobin showed a poor to modest activity against the disease even when applied at the highest application dose of 200 μg a.i. ha–1. Disease severity, in terms of AUDPC values was significantly correlated to decreased root yield, while no significant correlation existed among disease severity and sugar content of the roots or sucrose yield. In addition, the efficiency of tank mixtures of four strobilurin fungicides applied at 100 μg a.i. ha–1 with two sterol demethylation - inhibiting fungicides (DMIs, difenoconazole and cyproconazole applied at 62.5 and 25 mg a.i. ha–1, respectively, was evaluated. The mixtures of azoxystrobin and pyraclostrobin with either difenoconazole or cyproconazole provided a better control efficiency compared to the single application of each mixture partner, while the tank mixtures of trifloxystrobin and kresoxim-methyl with either difenoconazole or cyproconazole provided a better control efficiency compared to single application of difenoconazole or cyproconazole and similar control efficiency compared to the efficiency obtained by single application of the strobilurin fungicides.

    Acute pancreatitis during pregnancy is a severe disease with a high materno-fetal mortality, which recently decreased because of earlier diagnosis and improvement in maternal and neonatal intensive care. We describe a 19-year-old woman who presented at 37 weeks gestation with acute abdominal pain and attacks of vomiting. Obstetrical and fetal examinations were normal. Biochemical investigations and magnetic resonance imaging showed a gallstone migration with necrotizing pancreatitis (Balthazar 5 points). Our multidisciplinary team decided on nonsurgical conservative treatment including morphine administration and enteral feeding, and vaginal delivery which was possible 30 h after induction of labor. Follow up was uneventful with a resolution of pain and signs of pancreatitis on imaging. Magnetic resonance imaging can be useful and safe to estimate the severity of acute and necrotizing pancreatitis in the third trimester of pregnancy. In case of sterile necrotizing pancreatitis, nonsurgical conservative treatment and a vaginal delivery should be performed when possible in these patients to reduce the risk of maternal infection.

    Full Text Available Necrotizing fasciitis is a rare, life-threatening surgical infection in pregnancy with high rates of morbidity and mortality. A 15-year-old primigravid woman, at 28 weeks of gestation with no significant previous medical history, was admitted to our hospital complaining of severe left lower extremity pain and high fever the last 72 hours. During clinical examination, she had a swollen, erythematous and tender to palpation inflamed skin over the medial aspect of the upper thigh without any evidence of injury. Incision drainage was performed immediately and she received broad spectrum antibiotics. During initial laboratory examinations, diabetes mellitus was diagnosed. There was no clinical improvement over the following days. Magnetic resonance imaging (MRI revealed subcutaneous tissue inflammation and edema of infected tissues confirming the disease entity. Multidisciplinary therapy with immediate aggressive surgical debridement of necrotic tissues, multiple antibiotics, and intensive care monitoring was performed successfully. The patient’s postoperative course was uncomplicated and skin defect was closed with split thickness skin grafting. Our case emphasized the potential immunosuppressive role of pregnancy state in conjunction with diabetes mellitus in the development of severe necrotizing soft tissue infections.

    The objective of this retrospective study was to evaluate the outcome of patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy. By searching the radiological, surgical and internal medicine databases, all patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy between 1992 and 2004 were identified. Demographic, laboratory, and clinical data, and details about invasive procedures were collected by reviewing patient charts, radiological and surgical reports. The computed tomography severity index (CTSI) scores were determined by reviewing CT images. Eighteen patients were identified. Median Ranson score on admission was 2. The Acute Physiology and Chronic Health Evaluation (APACHE) II score was median 22. Median CTSI score was 7. Initially all patients were treated with CT-guided drainage placement. Because passive drainage proved not to be effective, subsequent minimally invasive, percutaneous necrosectomy was performed. Eight out of 18 patients recovered fully without the need for surgery. Ten of 18 patients required additional surgical necrosectomy. For one of ten patients, percutaneous necrosectomy allowed postponing surgery by 39 days. Four of ten surgically treated patients died: three from septic multiorgan failure, one from pulmonary embolism. Percutaneous minimally invasive necrosectomy can be regarded as a safe and effective complementary treatment modality in patients with necrotizing pancreatitis. It is suitable for a subset of patients to avoid or delay surgery. (orig.)

    Full Text Available Growing demand for better quality and cheaper products put on the need to industry to balance between the two kinds of needs, which are the reduction of production costs and to ensure a high quality product. This is the case with dried sugar beet pulp as a byproduct of sugar refining process. One of the possibilities to reduce energy consumption is savings in the process of thermal dehydration in the process of the conventional drying of pulp. Pulp drying is one third of total energy consumption in the sugar factory. Acidification of water extraction result in pulp that could be pressed better and in other hand in the juice with less non-sucrose compounds. Keeping the extraction process under certain conditions, directly affects on the quality of the extracted pulp and on effects of their further processing. This paper examines the impact of the extraction parameters of sugar from sugar beet and agents of acidification for water extraction (sulphurous acid, hydrogen peroxide on the quality of dried sugar beet pulp. Extraction of sugar from sugar beet cossettes by hydrogen peroxide at pH 5.5 to 8.5 does not cause changes in mechanical properties of sugar beet cossettes and in water retention coefficient, but increases the brightness of dried sugar beet pulp for about 5-7 units, which solubility in water does not depend on the applied concentration of extracting agents, but increases in dependence on the duration of the extraction. Sugar beet pulp extracted at pH 11.0 has reduced strength, they are highly hydrated, and under the force they lose their shape, binding a larger amount of water thus reducing the effect of their pressing. The changes in microstructure were probably accompanied by segmenting the linear parts of macromolecules and are reflected in the increase of water retention capacity and increase the solubility of dried sugar beet pulp for two to three times. Under the same conditions of extraction, sulphurous acid produces similar

    Sporamin, a sweet potato tuberous storage protein, is a Kunitz-type trypsin inhibitor. Its capability of conferring insect-resistance on transgenic tobacco and cauliflower has been confirmed. To test its potential as an anti-feedant for the beet cyst nematode (Heterodera schachtii Schm.), the sporamin gene SpTI-1 was introduced into sugar beet (Beta vulgaris L.) by Agrobacterium rhizogenes-mediated transformation. Twelve different hairy root clones expressing sporamin were selected for studying nematode development. Of these, 8 hairy root clones were found to show significant efficiency in inhibiting the growth and development of the female nematodes whereas 4 root clones did not show any inhibitory effects even though the SpTI-1 gene was regularly expressed in all of the tested hairy roots as revealed by northern and western analyses. Inhibition of nematode development correlated with trypsin inhibitor activity but not with the amount of sporamin expressed in hairy roots. These data demonstrate that the trypsin inhibitor activity is the critical factor for inhibiting growth and development of cyst nematodes in sugar beet hairy roots expressing the sporamin gene. Hence, the sweet potato sporamin can be used as a new and effective anti-feedant for controlling cyst nematodes offering an alternative strategy for establishing nematode resistance in crops.

    Full Text Available In Europe, the framework for sugar beet (Beta vulgaris L. production was subject to considerable changes and for the future it is expected that sugar beet cultivation might concentrate around the sugar factories for economic reasons. Based on data from a national sugar beet farmers’ survey and multi-year crop rotation trials, the effects of cropping interval (number of years in between two subsequent sugar beet crops and of preceding crops on sugar yield were elucidated under current Central European management conditions. The dominating sugar beet cropping interval was ≥4 years in the farm survey with pronounced differences between regions. However, the cropping intervals 2, 3, and ≥4 years did not affect the sugar yield. Therefore, significant differences in sugar yield between regions were assumed to be caused by multiple interactions between year, site, and farmers’ skills. Throughout Germany, the dominating preceding crops in sugar beet cultivation were winter wheat (Triticum aestivum L. and winter barley (Hordeum vulgare L.. In the field trials, the sugar yield was 5% higher after pea (Pisum sativum L. compared to maize (Zea mays L. as preceding crop, while differences between the preceding crops pea and winter wheat, and wheat and maize were not significant. Repeated measurements of canopy development and leaf color during the growing season revealed a higher N-availability after pea as preceding crop. However, decreased growth after maize was not completely compensated for by high N-fertilizer doses. Overall, the causes for the differences in sugar yield between the preceding crops remained open. The results do not support concerns about substantial yield losses in sugar beet production due to a reduction in the cropping interval from 3 to 2 years.

  6. The Role of Auxin-Ethylene Crosstalk in Orchestrating Primary Root Elongation in Sugar Beet

    It is well-established in Arabidopsis and other species that ethylene inhibits root elongation through the action of auxin. In sugar beet (Beta vulgaris L.) ethylene promotes root elongation in a concentration dependent manner. However, the crosstalk between ethylene and auxin remains unknown during sugar beet seedling development. Our experiments have shown that exogenously applied auxin (indole-3-acetic acid; IAA) also stimulates root elongation. We also show that auxin promotes ethylene biosynthesis leading to longer roots. We have further demonstrated that the auxin treatment stimulates ethylene production by redirecting the pool of available 1-aminocyclopropane-1-carboxylic acid (ACC) toward ethylene instead of malonyl-ACC (MACC) resulting in a prolonged period of high rates of ethylene production and subsequently a longer root. On the other hand we have also shown that endogenous IAA levels were not affected by an ACC treatment during germination. All together our findings suggest that the general model for auxin-ethylene crosstalk during early root development, where ethylene controls auxin biosynthesis and transport, does not occur in sugar beet. On the contrary, we have shown that the opposite, where auxin stimulates ethylene biosynthesis, is true for sugar beet root development. PMID:28424722

    Response surface methodology was used to optimise experimental conditions for ultrasonic-assisted extraction (UAE) of functional components from sugar beet molasses. The central composite design (CCD) was used for the optimisation of extraction parameters in terms of total phenolic contents, antioxidant activities and anthocyanins. Result suggested the optimal conditions obtained by RSM for UAE from sugar beet molasses were as follows: HCl concentration 1.55-1.72 mol/L, ethanol concentration 57-63% (v/v), extraction temperature 41-48 °C, and extraction time 66-73 min. In the optimal conditions, the experimental total phenolic contents were 17.36 mg GAE/100mL, antioxidant activity was 16.66 mg TE/g, and total anthocyanins were 31.81 mg/100g of the sugar beet molasses extract, which were well matched the predicted values. Teen compounds, i.e. gallic acid, vanillin, hydroxybenzoic acid, syringic acid, cyanidin-3-O-rutinoside, cyanidin-3-O-glucoside, catechin, delphinidin-3-O-rutinoside, delphinidin-3-O-glucuronide and ferulic acid were determined by HPLC-DAD-MS/MS in sugar beet molasses.

    This study details the introduction of a gfp marker into an endophytic bacterial strain (Achromobacter marplatensis strain 17, isolated from sugar beet) to monitor its colonization of sugar beet (Beta. vulgaris L.). Stability of the plasmid encoding the gfp was confirmed in vitro for at least 72 h of bacterial growth and after the colonization of tissues, under nonselective conditions. The colonization was observed using fluorescence microscopy and enumeration of culturable endophytes in inoculated sugar beet plants that grew for 10 or 20 days. gfp-Expressing strains were re-isolated from the inner tissues of surface-sterilized roots and stems of inoculated plants, and the survival of the Achromobacter marplatensis 17:gfp strain in plants 20 days after inoculation, even in the absence of selective pressure, suggests that it is good colonizer. These results also suggest that this strain could be a useful tool for the delivery of enzymes or other proteins into plants. In addition, the study highlights that sugar beet plants can be used effectively for detailed in vitro studies on the interactions between A. marplatensis strain 17 and its host, particularly if a gfp-tagged strain of the pathogen is used.

    Association mapping in multiple segregating populations (AMMSP) combines high power to detect QTL in genome-wide approaches of linkage mapping with high mapping resolution of association mapping. The main objectives of this study were to (1) examine the applicability of AMMSP in a plant breeding context based on segregating populations of various size of sugar beet (Beta vulgaris L.), (2) compare different biometric approaches for AMMSP, and (3) detect markers with significant main effect across locations for nine traits in sugar beet. We used 768 F(n) (n = 2, 3, 4) sugar beet genotypes which were randomly derived from 19 crosses among diploid elite sugar beet clones. For all nine traits, the genotypic and genotype x location interaction variances were highly significant (P < 0.01). Using a one-step AMMSP approach, the total number of significant (P < 0.05) marker-phenotype associations was 44. The identification of genome regions associated with the traits under consideration indicated that not only segregating populations derived from crosses of parental genotypes in a systematic manner could be used for AMMSP but also populations routinely derived in plant breeding programs from multiple, related crosses. Furthermore, our results suggest that data sets, whose size does not permit analysis by the one-step AMMSP approach, might be analyzed using the two-step approach based on adjusted entry means for each location without losing too much power for detection of marker-phenotype associations.

    The interfacial and emulsion-forming properties of sugar beet extract (Beta vulgaris L.) were examined and compared to a Quillaja extract that is widely used within the food industry. We investigated the influence of extract concentration on surface activity at oil-water and air-water interfaces and on the formation of oil-in-water emulsions (10% w/w, pH 7). Sugar beet extract reduced the interfacial tension up to 38% at the oil-water interface, and the surface tension up to 33% at the air-water surface. The generated emulsions were negatively charged (ζ ≈ -46 mV) and had the smallest particle sizes (d 43 ) of ∼1.3 μm at a low emulsifier-to-oil ratio of 0.75:10. Applying lower or higher extract concentrations increased the mean particle sizes. The smallest emulsions were formed at an optimum homogenization pressure of 69 MPa. Higher homogenization pressures led to increased particle sizes. Overall, sugar beet extract showed high surface activity. Furthermore, the formation of small emulsion droplets was successful; however, the droplets were bigger compared to those from the Quillaja extract. These results indicate sugar beet as an effective natural emulsifier that may be utilized for a variety of food and beverage applications.

    The maize Activator/Dissociation (Ac/Ds) transposable element system was introduced into sugar beet. The autonomous Ac and non-autonomous Ds element excise from the T-DNA vector and integrate at novel positions in the sugar beet genome. Ac and Ds excisions generate footprints in the donor T-DNA that support the hairpin model for transposon excision. Two complete integration events into genomic sugar beet DNA were obtained by IPCR. Integration of Ac leads to an eight bp duplication, while integration of Ds in a homologue of a sugar beet flowering locus gene did not induce a duplication. The molecular structure of the target site indicates Ds integration into a double strand break. Analyses of transposase transcription using RT-PCR revealed low amounts of alternatively spliced mRNAs. The fourth intron of the transposase was found to be partially misspliced. Four different splice products were identified. In addition, the second and third exon were found to harbour two and three novel introns, respectively. These utilize each the same splice donor but several alternative splice acceptor sites. Using the SplicePredictor online tool, one of the two introns within exon two is predicted to be efficiently spliced in maize. Most interestingly, splicing of this intron together with the four major introns of Ac would generate a transposase that lacks the DNA binding domain and two of its three nuclear localization signals, but still harbours the dimerization domain.

    Full Text Available It is necessary not only to possess the technology to grow seeds but also to have knowledge of plant biology in particular crop, and sowing qualities of its seeds. The particular place where seeds are forming on the mother plant has much influence on qualities of sowing seed material. The influence of the development of red beet plant bush on seed productivity, monogermity and sowing qualities of seeds was estimated in Rostov oblast. The main stalk pruning and application of plant growth retardants had an effect on the structure of red beet bush. In variants given in seed plants, the third type of branching prevailed due to lack or oppression of main stalk. Consequently, the seed yield and proportion of single fruit formation rose. It was also shown that due to treatment of plants with growth retardant ‘Floron’ at the stage of waxen maturity significantly improved the seed germination as compared with control variant. As a result of the study it was shown that the mechanical pruning of main stalk and application of growth retardants had affected on the structure of seed red beet bush increasing the yield mono-seed compounds as well as had improved the yield and seed quality of monogerm red beet

    2017-05-01

    Full Text Available Introduction Sugar beet (Beta vulgaris L. as the second most important world’s sugar source after sugarcane is one of the major industrial crops. The presence of weeds in sugar beet fields, especially at early growth stages, results in a substantial decrease in the crop yield. It is very important to efficiently eliminate weeds at early growing stages. The first step of precision weed control is accurate detection of weeds location in the field. This operation can be performed by machine vision techniques. Hough transform is one of the shape feature extraction methods for object tracking in image processing which is basically used to identify lines or other geometrical shapes in an image. Generalized Hough transform (GHT is a modified version of the Hough transform used not only for geometrical forms, but also for detecting any arbitrary shape. This method is based on a pattern matching principle that uses a set of vectors of feature points (usually object edge points to a reference point to construct a pattern. By comparing this pattern with a set pattern, the desired shape is detected. The aim of this study was to identify the sugar beet plant from some common weeds in a field using the GHT. Materials and Methods Images required for this study were taken at the four-leaf stage of sugar beet as the beginning of the critical period of weed control. A shelter was used to avoid direct sunlight and prevent leaf shadows on each other. The obtained images were then introduced to the Image Processing Toolbox of MATLAB programming software for further processing. Green and Red color components were extracted from primary RGB images. In the first step, binary images were obtained by applying the optimal threshold on the G-R images. A comprehensive study of several sugar beet images revealed that there is a unique feature in sugar beet leaves which makes them differentiable from the weeds. The feature observed in all sugar beet plants at the four

    Full Text Available Allelopathic effects of barley straw and root on germination and growth of maize, sugar beet, and sunflower were investigated under glasshouse and laboratory experiments in Faculty of Agriculture, Ferdowsi University of Mashhad in 2006. The glasshouse experiment was designed based on randomized complete block design with three replications, treatments included: 0, 200, 400, 600 g/m² of grounded barley straw and also 0 and 50 g/m2 barley root. A laboratory experiment was carried out in order to study the effect of different concentrations of barley water extracts on germination and seedling characteristics of corn, sugar beet and sunflower. Treatments in laboratory trial included 0, 33, 50 and 100 percent of barley extracts. Results showed that leaf area of corn was significantly affected by barley straw treatments. Shoot dry matter and seed weight per plant in corn , leaf and tuber weight in sugar beet and leaf , stem weights , plant per plant in corn , leaf and tuber weight in sugar beet and leaf, stem weights, plant height, head diameter, head weight and seed weight in sunflower were significantly higher in treatment of 50g/m² barley roots. Crop seed germination decreased with increasing the amount of barley straw. The best germination response to barley extract was observed in corn. Maize radicle weight was significantly decreased with increasing concentration of barley water extract.

    Sugar beet pulp residues (SBPR) from hydrolysis and dewatering of beet pulp were co-digested with municipal sewage sludge (MSS). The highest biogas yields of nearly 512 dm(3)/kg VSfed (volatile solids fed) were achieved for SBPR, treated both as the monosubstrate and as a mixture with MSS (1 : 1 by weight). Simultaneously, the highest methane production of 348 dm(3) CH4/kg VSfed was determined when the sewage sludge was co-digested with 35% SBPR. The analysis of digestate showed that neither ammonia nor volatile fatty acids destabilized the biogas production. Processing of sugar beet pulp into bioethanol via enzymatic hydrolysis and microbial fermentation has become increasingly attractive. However, in this process, only the liquid fraction derived from hydrolysis is subjected into alcoholic fermentation, whereas the remaining solid fraction needs to be utilized. This study demonstrated that sugar beet pulp residues after bioethanol production can successfully be co-digested with sewage sludge to increase biogas productivity of anaerobic digesters located at wastewater treatment plants.

    2016-01-01

    Biological macromolecules such as starches of different amylaceous sources have been used in the formulation of edible films. However, there are few studies aimed at evaluating edible and intelligent films with response to pH changes from natural pigments, this despite the importance of these materials. In this context, films from native and modified plantain flour, plasticized with glycerol, with or without the addition of beet flour were developed. The chemical and structural composition of the flours, and its incidence on thickness, water solubility, contact angle, and mechanical and microstructural properties were evaluated, thus as its response to pH changes of the developed films. The observations showed that the incorporation of beet flour allowed to obtain intelligent films front to pH changes alkaline. Likewise, the betalains that were found in beet flour interacted more efficiently with the phosphated plantain flour, limiting well its immediate response to pH changes. In the same way, proteins and sugars of beet flour allowed to obtain more flexible films, due to the hydrogen bond interactions between these constituents and the plantain flours. This latter could justify the decrease of contact angle, and the increase on thickness and solubility of these films. Copyright © 2015 Elsevier B.V. All rights reserved.

    The experiment was conducted at a research station near Adlib. Two irrigation methods, sprinkler irrigation and drip fertigation, two phosphorus rates and four nitrogen rates 0, 70, 140 and 210 kg N/ha were tested. All N fertilizers were injected for drip irrigation or broadcasted for the sprinkler-irrigated treatments in six equally split applications. Neutron probe Results revealed that the introduction of drip fertigation was not proved to be a water saving relative to sprinkler irrigation. Dry matter production was slightly increased for the drip-fertigated treatments relative to sprinkler irrigated treatments. Nitrogen use efficiency was not improved under drip fertigation relative to that of sprinkler irrigation. Application of phosphorus fertilizer improved sugar beet yield as well as N uptake. No significant differences in sugar beet yield were observed due to the application of N fertilizer under drip fertigation. On the other hand, there was a trend toward increasing sugar beet yield grown under sprinkler irrigation. Drip fertigation had no negative effects on sugar content and other related properties, furthermore some of those properties were enhanced due to the employment of drip fertigation. Field water-use efficiency followed a similar trend and was increased under sprinkler irrigation relative to drip-fertigation for sugar beet yield parameter.

    2014-02-01

    Full Text Available The article considers main methodical approaches to formation of information support in management of production of sugar beet. It conducts analysis, systematisation and generalisation of theoretical developments of scientists with respect to definition of the “information support” notion, which allows formulation of the author’s vision. The article considers definitions of the expenditures notion as one of the central categories in management of production and types of cost value as objects of management. The article proves that business accounting is in close connection with the managerial system, which, consequently, determines a specific role of expenditures in enterprise management. It identifies topical directions of formation of information support in management of production of sugar beet. On the basis of the study of practice of sugar growing enterprises the article forms main data carriers within stages of the accounting process with the aim to carry out efficient management of sugar beet production. The prospect of further studies is improvement of information support in the beet growing industry through: development of accounting policy; system of primary documents by means of formation of product quality indicators; automation of formation of their indicators with the purpose of operative control; development of budgets for planning production indicators with the purpose of management and control.

    Full Text Available To investigate the effect of water stress and rewatering on sugar beet yield and its corresponding photosynthetic parameters, and to provide the basis of water management for the sugar beet fields, pool experiments in an artificial proof canopy were set up to observe changes of beet net photosynthetic rate(Pn, transpiration rate(Tr, water use efficiency(WUE and stomatal limitation (Ls, intercellular CO2 oncentration(Ci, and PSⅡ maximum quantum yield(Fv/Fm. The results indicated that the diurnal variation of Tr and Pn in CK treatment (whole growth period replenishment at different times near "unimodal" type; and water shortage treatments presented "twin peaks" change. Diurnal transpiration capacity(DTC under water stress at sugar accumulation stage reduced by 70.16%~74.81% and diurnal photosynthetic capacity(DPC was 63.48%~69.96% lower than that of CK, while diurnal water use efficiency(WUEd increased by 19.28%~22.39%. Rehydration helped Tr and Pn recovery, but did not reach unstressed levels. Ls changes under extremely dry environment had a midday trough "twin peaks" feature, and Ci was at "double-dip" in consistent with the timing of Ls; Water stress inhibited and inactivated photochemical reaction center of midday PSⅡ. Water stress led to irreversible decrease in the Pn and Tr, and prolonged the Pn inefficient period, which become the important factor of influencing the sugar beet yield.

  6. USE OF GREEN MANURE CROPS AND SUGAR BEET VARIETIES TO CONTROL HETERODERA BETAE.

    Raaijmakers, E

    2014-01-01

    Although it is less studied than the white beet cyst nematode (Heterodera schachtii), the yellow beet cyst nematode (H. betae) has been found in many countries in Europe. For example in The Netherlands, France and Spain. H. betae causes yield losses on sandy soils. A high infestation can result in loss of complete plants. In The Netherlands, this nematode is especially found in the south eastern and north eastern part, where it occurs on 18% and 5% of the fields, respectively. From a project of the Dutch Sugar beet Research Institute IRS (SUSY) on factors explaining differences in sugar yield, this nematode was one of the most important factors reducing sugar yields on sandy soils. Until 2008, the only way to control H. betae was by reducing the number of host crops in the crop rotation. Host crops are crops belonging to the families of Cruciferae, Chenopodiaceae, Polygonaceae, Caryophyllaceae and Leguminosea. In order to find more control measures, research was done to investigate the host status of different green manure crops and the resistance and tolerance of different sugar beet varieties to H. betae. White mustard (Sinapis alba) and oil seed radish (Raphanus sativus spp. oleiferus) varieties resistant to H. schachtii were investigated for their resistance against H. betae. A climate room trial and a field trial with white mustard and oil seed radish were conducted in 2007 and 2008, respectively. Results show that H. betae could multiply on susceptible white mustard and susceptible oil seed radish, but not on the H. schachtii resistant varieties. In climate room trials in 2009, 2010 and 2011 and field trials in 2010, 2011 and 2012, the effect of different sugar beet varieties on the multiplication of H. betae and the effect of H. betae on yield at different infestation levels was investigated. Sugar beet varieties with resistance genes to H. schachtii (from Beta procumbens or B. maritima) were selected. Varieties with resistance genes from these sources were

    Enzymatic degradation of plant biomass requires a complex mixture of many different enzymes. Like most fungi, thermophilic Myceliophthora species therefore have a large set of enzymes targeting different linkages in plant polysaccharides. The majority of these enzymes have not been functionally characterized, and their role in plant biomass degradation is unknown. The biotechnological challenge is to select the right set of enzymes to efficiently degrade a particular biomass. This study describes a strategy using sexual crossing and screening with the thermophilic fungus Myceliophthora heterothallica to identify specific enzymes associated with improved sugar beet pulp saccharification. Two genetically diverse M. heterothallica strains CBS 203.75 and CBS 663.74 were used to generate progenies with improved growth on sugar beet pulp. One progeny, named SBP.F1.2.11, had a different genetic pattern from the parental strains and had improved saccharification activity after the growth on 3 % sugar beet pulp. The improved SBP saccharification was not explained by altered activities of the major (hemi-)cellulases. Exo-proteome analysis of progeny and parental strains after 7-day growth on sugar beet pulp showed that only 17 of the 133 secreted CAZy enzymes were more abundant in progeny SBP.F1.2.11. Particularly one enzyme belonging to the carbohydrate esterase family 5 (CE5) was more abundant in SBP.F1.2.11. This CE5-CBM1 enzyme, named as Axe1, was phylogenetically related to acetyl xylan esterases. Biochemical characterization of Axe1 confirmed de-acetylation activity with optimal activities at 75-85 °C and pH 5.5-6.0. Supplementing Axe1 to CBS 203.75 enzyme set improved release of xylose and glucose from sugar beet pulp. This study identified beneficial enzymes for sugar beet pulp saccharification by selecting progeny with improved growth on this particular substrate. Saccharification of sugar beet pulp was improved by supplementing enzyme mixtures with a previously

    The establishment of stress resilient sugar beets (Beta vulgaris spp. vulgaris) is an important breeding goal since this cash crop is susceptible to drought and salinity. The genetic diversity in cultivated sugar beets is low and the beet wild relatives are useful genetic resources for tolerance traits. Three wild beet populations (Beta vulgaris spp. maritima) from contrasting environments, Vaiamonte (VMT, dry inland hill), Comporta (CMP, marsh) and Oeiras (OEI, coastland), and one commercial sugar beet (Isella variety, SB), are compared. At the genetic level, the use of six microsatellite allowed to detect a total of seventy six alleles. It was observed that CMP population has the highest value concerning the effective number of alleles and of expected heterozygosity. By contrast, sugar beet has the lowest values for all the parameters considered. Loci analysis with STRUCTURE allows defining three genetic clusters, the sea beet (OEI and CMP), the inland ruderal beet (VMT) and the sugar beet (SB). A screening test for progressive drought and salinity effects demonstrated that: all populations were able to recover from severe stress; drought impact was higher than that from salinity; the impact on biomass (total, shoot, root) was population specific. The distinct strategies were also visible at physiological level. We evaluated the physiological responses of the populations under drought and salt stress, namely at initial stress stages, late stress stages, and early stress recovery. Multivariate analysis showed that the physiological performance can be used to discriminate between genotypes, with a strong contribution of leaf temperature and leaf osmotic adjustment. However, the separation achieved and the groups formed are dependent on the stress type, stress intensity and duration.

    Abstract Fine-tuned and coordinated regulation of transport, metabolism and redox homeostasis allows plants to acclimate to osmotic and ionic stress caused by high salinity. Sugar beet is a highly salt tolerant crop plant and is therefore an interesting model to study sodium chloride (NaCl) acclimation in crops. Sugar beet plants were subjected to a final level of 300 mM NaCl for up to 14 d in hydroponics. Plants acclimated to NaCl stress by maintaining its growth rate and adjusting its cellular redox and reactive oxygen species (ROS) network. In order to understand the unusual suppression of ROS accumulation under severe salinity, the regulation of elements of the redox and ROS network was investigated at the transcript level. First, the gene families of superoxide dismutase (SOD), peroxiredoxins (Prx), alternative oxidase (AOX), plastid terminal oxidase (PTOX) and NADPH oxidase (RBOH) were identified in the sugar beet genome. Salinity induced the accumulation of Cu-Zn-SOD, Mn-SOD, Fe-SOD3, all AOX isoforms, 2-Cys-PrxB, PrxQ, and PrxIIF. In contrast, Fe-SOD1, 1-Cys-Prx, PrxIIB and PrxIIE levels decreased in response to salinity. Most importantly, RBOH transcripts of all isoforms decreased. This pattern offers a straightforward explanation for the low ROS levels under salinity. Promoters of stress responsive antioxidant genes were analyzed in silico for the enrichment of cis-elements, in order to gain insights into gene regulation. The results indicate that special cis-elements in the promoters of the antioxidant genes in sugar beet participate in adjusting the redox and ROS network and are fundamental to high salinity tolerance of sugar beet PMID:28338762

    Red beet (Beta vulgaris L.) is a traditional and popular vegetable distributed in many part of the world and has been used as a natural colorant in many dairy products, beverages, candies and cattle products. Red beet roots contain two groups of betalain pigments, redviolet betacyanins and yellow betaxanthins. Betalains possess several biological activities such as antioxidant, anti-inflammatory, hepatoprotective, and anticancer properities. Recent trend of using natural products in industries tends toward multifunctional, high quality, and highpriced value foods and cosmetics. To meet the needs of consumers, cosmetics, medicine, and foods should contain the proper amount of natural products. Although the color removal processes such as filtration and absorption by clay are still useful, these procedures are difficult, time-consuming and costly. To overcome this problem, the radiation technology has emerged as a new way. Radiation technology has been applied to the decomposition and decoloration of pigment and is an efficient technique for inactivating pathogens, removing undesirable color in biomaterial extracts and improving or maintaining biological activities. Gamma-irradiation and electron beamirradiation techniques in previous reports were applied in order to remove any undesirable color and to improve or maintain biological activities of various extracts such as green tea leaves, licorice root, and S. chinensis fruits. Latorre et al. reported that betacyanin concentration decreased with the irradiation dose and significantly, in 35%, after 2.0 kGy of gamma-ray, whereas betaxathin concentration increased (about 11%-ratio with respect to control) after 1 kGy but decreased (about 19%) after 2 kGy. However, they did not try to analysis for completed removal of red beet pigments. Therefore, it is necessary to find the optimum irradiation dose for entirely removing red pigments in red beet. The aim of this work was to address the effects of the color removal and

    This study tested the hypothesis that the easily degradable carbohydrates of the sugar beet silage (S) will improve the anaerobic digestion of grass silage (G) more profoundly compared to co-digestion of sugar beet silage with maize silage (M). M : S and G : S mixtures were tested in two continuous laboratory-scale AD experiments at volatile solid ratios of 1 : 0, 6 : 1, 3 : 1, and 1 : 3 at organic loading rates of 1.5 kgVS m−3 day−1. While the sugar beet effects in mixtures with maize silage were negligible, co-digestion with grass silage showed a beneficial performance. There, the specific methane production rate was 0.27 lN kg−1VS h−1at G : S ratio of 6 : 1 compared to G : S 1 : 0 with 0.14 lN kg−1VS h−1. In comparison to G : S 1 : 0, about 44% and 62% higher biogas yields were obtained at G : S 6 : 1 and 3 : 1, respectively. Also, the highest methane concentration was found in G : S at ratio of 1 : 3. Synergistic increase of methane yield was found in co-digestion in both experiments, but higher effect was realized in G : S, independently of the amount of sugar beet silage. The findings of this study emphasize the improvement of AD of grass silage by even low addition of sugar beet silage. PMID:27807538

    Obtaining dedifferentiated cells (callus) that can regenerate into whole plants is not always feasible for many plant species. Sugar beet is known to be recalcitrant for dedifferentiation and plant regeneration. These difficulties were major obstacles for obtaining transgenic sugar beets through an Agrobacterium -mediated transformation procedure. The sugar beet line 'NK-219mm-O' is an exceptional line that forms callus efficiently and is easy to regenerate, but the inheritance of these characters was unknown. Another concern was whether these characters could coexist with an annual habitat that makes it possible to breed short life-cycle sugar beet suitable for molecular genetic analysis. Five sugar beet lines including NK-219mm-O were crossed with each other and subjected to in vitro culture to form callus. F 1 s with a NK-219mm-O background generally formed callus efficiently compared to the others, indicating that efficient callus formation is heritable. The regeneration potential was examined based on the phenotypes of calli after placement on regeneration medium. Five phenotypes were observed, of which two phenotypes regenerated shoots or somatic embryo-like structures. Vascular differentiation was evident in regenerable calli, whereas non-regenerable calli lacked normally developed vascular tissues. In a half-diallel cross, the callus-formation efficiency and the regeneration potential of reciprocal F 1 s progeny having a NK-219mm-O background were high. Finally, we crossed NK-219mm-O with an annual line that had a poor in vitro performance. The callus-formation efficiency and the regeneration potential of reciprocal F 1 were high. The regenerated plants showed an annual habitat. Efficient callus formation and the high plant regeneration potential of NK-219mm-O were inherited and expressed in the F 1 . The annual habitat does not impair these high in vitro performances.

    Table beet (Beta vulgaris var. rubra) contains important bioactive agents (betaine and polyphenols), which have a wide range of physiologic effects. Because nutritive antioxidants may reduce the occurrence of complications and postoperative mortality, dietary intake of polyphenols and vitamins before surgery may greatly contribute to the survival of patients. Our aim was to determine the liver-protecting properties of bioactive substances of table beet in a model of ischemia-reperfusion injury of the rat. Wistar rats were divided into two groups: non-treated (n = 24) and fed with table beet (n = 8). For 10 days the second group was treated with lyophilized table beet (2 g/kg body weight daily) mixed into the rat chow. Hepatic ischemia was maintained for 45 min, followed by 15 min of reperfusion. Ischemia-reperfusion was carried out on animals from both groups. Chemiluminescent intensity, H-donating ability, reducing power, free SH group concentration, Randox-total antioxidant status, glutathione peroxidase, and superoxide dismutase activities were determined by luminometry and spectrophotometry. Fatty acid (Shimadzu GC) and metal ion (inductively coupled plasma optical emission spectrometry) concentrations were observed in the liver. As a result of feeding, global parameters (H-donating ability, reducing power, free SH group concentration) and enzymatic antioxidants (glutathione peroxidase and superoxide dismutase) of the liver were found to increase significantly, which indicated that the treatment had a positive effect on its redox state. The increase found in zinc and copper content may protect the hepatocytes against oxidative stress because these elements are required for the function of superoxide dismutase enzymes. In the table beet group the concentration of short-chain fatty acids decreased, whereas that of long-chain fatty acids increased. The changes in metal element and fatty acid concentrations confirmed that these elements have an essential function

    Full Text Available The aim of the investigation was to determine the influence of Clostridium perfringens type A on the development of pathomorphological substrate, its intensity and distribution in fifteen weeks old heavy breeds broilers. The investigation was carried out on corpses of 8 hens and 7 roosters of heavy breeds of provenance COBB 500. After the completion of the autopsy, samples of altered parts of jejunum and liver were taken for histopathological examination, and jejunum intestinal contents for bacteriological examination. In all the corpses, in open pleuroperitoneal cavity, even in situ, an altered part of jejunum can be noticed. It was extremely dilated the entire length, and its wall was bluish-gray with disseminated subserous punctiform blood extravasates. When opened, semi-liquid content with blood coagulums and patches of necrotic mucosa went out of it. By microscopic examination of small intestine tissue cuttings, colored by HE method, there was observed a diffuse necrosis of intestinal villi. They were desroyed and replaced by eosinophilic structureless mass. Furthermore, there could be noticed submucose oedema, capillary congestion and blood extravasates in mucosa, as well as infiltration of neutrophilic granulocytes in lamina propria. These microscopic alterations reflect hemorrhagic necrotic enteritis. By microscopic examining of small intestine cuttings colored according to Brown & Brenn method, colonies of bacteria in distal parts of the submucosa were found out. Using bacteriological tests in anaerobic conditions, there was isolated a culture identified as Clostridium perfringens. After applying of multiplex PCR, the obtained isolate was genotyped as Clostridium perfringens type A. On the basis of pathomorphological, bacteriological and molecular examinations, it can be concluded that the infection of heavy breeds with Clostridium perfringens type A is manifested by appearance of haemorrhagic-necrotic jejunitis, that the causer

    One extremely rare complication of chemotherapy for hematologic malignancies that is burdened with a high mortality rate (50%-80%) is necrotizing gastritis and gastric gangrene as result of poor clinical outcome of neutropenic gastritis (NG). We present a unique case of a neutropenic patient with necrotizing full thickness gastritis due to bacterial and fungal infection. Up to date only few such cases have been reported in world literature. A 28-year-old patient was subjected to dose-escalated BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone), (chemotherapy regimen) for Hodgkin lymphoma. In neutropenic patient abdominal pain, bleeding from the alimentary tract was observed. Hemorrhagic gastritis was recognized at endoscopy and CT demonstrated marked gastric wall thickness. Following NG diagnosis intensive treatment was initiated. On day 2 the patient's condition deteriorated (septic shock, multiple organ failure). Repeat endoscopy revealed gastric necrosis and laparotomy was performed. As consequence of cardiac arrest and cardiopulmonary resuscitation the surgical procedure was limited to total gastrectomy, feeding jejustomy and esophageal drainage through nasoesophageal catherization. Roux-loop esophagojejunostomy was performed on day 22 and supplemented 4 days later by endoscopic placement of covered self-expandable stent due to anastomosis leak. The procedure proved successful and oral feeding was well-tolerated. The patient was discharged in 32 days following recognition of gastric necrosis. Chemotherapy complications in neutropenic patients are life-threatening conditions. Immediate pharmacological treatment usually leads to improvement. Surgical management usually the resection of necrotic zones is restricted to cases of poor prognosis or deterioration of patient's condition and complications.

    Full Text Available Clostridium perfringens (C. perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen causing necrotic enteritis. C. perfringens only causes necrotic enteritis when it transforms from non-toxin producing type to toxin producing type. The alpha toxin, (phospholipase C is believed to be a key to the occurrence of Clostridial necrotic enteritis (CNE. The best known predisposing factor is mucosal damage, caused by coccidiosis that damages the intestinal lining, making the gut susceptible to infections including C. perfringens. The purpose of this study was to observe the chicken performance in experimental CNE and field cases of CNE. Diagnosis of CNE were made by latex agglutination test, isolation and identification of the agent. Pathological and histopathological changes were also observed. Experimentally, NE could be reproduced when Eimeria sp and C. perfringens spores are inoculated in chicken. Signs of an NE are wet litter and diarrhea, and an increase in mortality is not often obvious. The depression of growth rate and feed efficiency of chicken become noticeable by week 5 because of damage to the intestine and the subsequent reduction in digestion and absorption of food. Subclinical form of CNE was also frequently found in the field, leading to significant decreases in performance. Chicken gut samples examinations revealed that subclinical form of CNE causes damage to the intestinal mucosa caused by C. perfringens leads to decreased digestion and absorption, increased feed conversion ratio and reduced weight gain. Dual infection with C. perfringens and Eimeria sp. was frequently found in field. The results of these studies provide evidence for C. perfringens as a causative bacteria for growth depression.

    Full Text Available Malignant otitis externa (MOE is a severe infection of external auditory canal and skull base. A 17-year-old diabetic girl was admitted with diabetic ketoacidosis. Cellulitis of her right ear occurred on the second day of hospitalization and a black necrotic scar in the same region appeared on the next day. The lesion rapidly invaded to right side of neck and surrounding tissue of the patient. Therefore, antimycotic therapy was started. Unfortunately the patient died on seventh day of hospitalization because of probably extensive fungal invasion. Physicians should suspect MOE connected to mucormycosis especially in patients with cutaneous lesions of ear unresponsive to antibiotic therapy.

    Necrotizing fasciitis (NF) is an infrequently encountered skin infection that has high morbidity and mortality, even with prompt medical and surgical intervention. We describe the case of a 67-year-old male presenting with significant NF in his left lower extremity, despite aggressive surgical intervention, and included multiple surgical debridements, ACell Matrix, split-thickness, and negative wound VAC therapy. Ultimately, this patient required a below the knee amputation. This is the first documented case of Haemophilus influenza type a causing NF. PMID:29124073

    We profiled triterpene saponins from the roots of sugar beet Beta vulgaris L. cultivars Huzar and Boryna using reversed-phase liquid chromatography combined with negative-ion electrospray ionization quadrupole mass spectrometry. We tentatively identified 26 triterpene saponins, including 17 that had not been detected previously in this plant species and 7 saponins that were tentatively identified as new compounds. All observed compounds were glycosides of five different aglycones, of which gypsogenin and norhederagenin are reported for the first time in sugar beet. Thirteen of the saponins detected in sugar beet roots were substituted with dioxolane-type (4 saponins) or acetal-type (9 saponins) dicarboxylic acids. Among the 26 detected saponins, we identified 2 groups of isomers distinguished using high-resolution mass measurements that were detected only in the Huzar cultivar of sugar beet.

    By integrating molecular, biochemical, and physiological data, ethylene biosynthesis in sugar beet was shown to be differentially regulated, affecting root elongation in a concentration-dependent manner. There is a close relation between ethylene production and seedling growth of sugar beet (Beta vulgaris L.), yet the exact function of ethylene during this early developmental stage is still unclear. While ethylene is mostly considered to be a root growth inhibitor, we found that external 1-aminocyclopropane-1-carboxylic acid (ACC) regulates root growth in sugar beet in a concentration-dependent manner: low concentrations stimulate root growth while high concentrations inhibit root growth. These results reveal that ethylene action during root elongation is strongly concentration dependent. Furthermore our detailed study of ethylene biosynthesis kinetics revealed a very strict gene regulation pattern of ACC synthase (ACS) and ACC oxidase (ACO), in which ACS is the rate liming step during sugar beet seedling development.

    A quantitative PCR method (qPCR) was developed for the detection and quantification of Ramularia beticola causing Ramularia leaf spot in sugar beet. R. beticola specific primers were designed based on the internal transcribed spacer region 2 (ITS2). The assay was applied on DNA extracted from...... spores trapped on tape from Burkard spore traps placed in an artificially inoculated sugar beet field trial and in two sugar beet fields with natural infections. R. beticola DNA was detected at variable amounts in the air samples 14 to 16 days prior to first visible symptoms. R. beticola DNA was detected....... beticola in plant material and in air samples prior to the appearance of visible symptoms. An early detection has potential as a tool, which can be part of a warning system predicting the onset of the disease in the sugar beet crop and helping to optimise fungicide application....

  13. A sugar beet chlorophyll a/b binding protein promoter void of G-box like elements confers strong and leaf specific reporter gene expression in transgenic sugar beet

    2004-12-01

    Full Text Available Abstract Background Modification of leaf traits in sugar beet requires a strong leaf specific promoter. With such a promoter, expression in taproots can be avoided which may otherwise take away available energy resources for sugar accumulation. Results Suppression Subtractive Hybridization (SSH was utilized to generate an enriched and equalized cDNA library for leaf expressed genes from sugar beet. Fourteen cDNA fragments corresponding to thirteen different genes were isolated. Northern blot analysis indicates the desired tissue specificity of these genes. The promoters for two chlorophyll a/b binding protein genes (Bvcab11 and Bvcab12 were isolated, linked to reporter genes, and transformed into sugar beet using promoter reporter gene fusions. Transient and transgenic analysis indicate that both promoters direct leaf specific gene expression. A bioinformatic analysis revealed that the Bvcab11 promoter is void of G-box like regulatory elements with a palindromic ACGT core sequence. The data indicate that the presence of a G-box element is not a prerequisite for leaf specific and light induced gene expression in sugar beet. Conclusions This work shows that SSH can be successfully employed for the identification and subsequent isolation of tissue specific sugar beet promoters. These promoters are shown to drive strong leaf specific gene expression in transgenic sugar beet. The application of these promoters for expressing resistance improving genes against foliar diseases is discussed.

    This study examines the influence of ensiled sugar beets (Beta vulgaris ssp. vulgaris) on preference and short-time dry matter (DM) intake of goats. Whole sugar beets were ensiled either without any silage additive (sugar beet silage (SBS)) or with a chemical additive (6 l/t) containing 85% formic and propionic acids (treated sugar beet silage (TBS)) and were chopped after ensiling. The influence of different proportions of SBS (0%, 6.25%, 12.5%, 18.75% and 25% of dietary DM) and TBS (0%, 5%, 10%, 15% and 20% of DM) in partial mixed rations on short-time DM intake by goats (adult Saanen type wethers; n = 10) was studied in two separate, independent trials. Preference behaviour was investigated by offering the goats two different experimental diets per day and offer each possible combination of them (n = 10) once throughout the trial. On this basis, the mean DM intake (within 30 min and 3 h) of each experimental diet was determined. Both sugar beet silages showed good fermentation quality with low pH. By using the chemical silage additive, the production of ethanol was reduced and considerable amounts of sugar were preserved. In the short-term preference experiment, increasing concentrations of sugar beet silage in the ration increased DM intake (p < 0.05) in a linear way with a strong preference for those diets containing high amounts of sugar beet silage. Initial DM intake after 30 min was 4-5 fold increased for diets containing the highest beet concentration. It is assumed that the preference was positively influenced by sugar and sweet taste or the associated higher concentration of metabolisable energy.

    2014-01-01

    Full Text Available Introduction. If the teeth are impacted by a chronic irritant, the pulp space possibly will undergo calcific changes that may impede access opening during root canal treatment. In such cases that conventional endodontic treatment is impossible or impractical, intentional replantation may be considered as a last solution to preserve the tooth. Methods. After failing to perform conventional root canal therapy for a necrotic calcified right mandibular second premolar, the tooth was gently extracted. The root apex was resected and the root end cavity was prepared and filled with calcium enriched mixture (CEM cement. Then, the extracted tooth was replanted in its original position. Results. After a year the tooth was asymptomatic, and the size of periapical radiolucency was remarkably reduced and no clinical sign of ankylosis was observed. Conclusion. Intentional replantation of the necrotic calcified teeth could be considered as an alternative to teeth extraction, especially for the single-rooted teeth and when nonsurgical and surgical endodontic procedures seem impossible.

    Full Text Available Objectives. The aim of this study was to characterize the lesions of necrotizing gingivitis (NG and necrotizing periodontitis (NP with regard to extent and severity, and to correlate these parameters with the host HIV serostatus, CD4+ T-cell count, neutrophil count, age, and gender. Methods. Eighty-four consecutive patients, 39 black females and 45 black males aged 20–46 years, diagnosed with NG/NP were recruited to the study over a period of two years. Results. For both HIV-seropositive and -seronegative patients, the mandibular anterior gingiva was most frequently affected; 74% had NG/NP affecting ≥5 gingival tooth sites. Ninety percent of all patients had a mean severity of ≤4 mm. There was no statistically significant association between either extent or severity of NG/NP and HIV serostatus, CD4+ T-cell count, neutrophil count, age, or gender. The difference between the number of HIV-seropositive patients with NG/NP who had CD4+ T-cell counts ≤200 cells/mm3 and those who had CD4+ T cell counts of 201–499 cells/mm3 was not statistically significant. Conclusion. The clinical signs of NG/NP are similar in HIV-seropositive and -seronegative patients, and are not related to CD4+ T-cell count, to neutrophil count, to gender, or to age.

    To define the characteristics of necrotizing sarcoid granulomatosis (NGS) a very rare pulmonary disease hardly recognised by pulmonologists and pathologists. PubMed was searched for the term necrotising or necrotizing sarcoid granulomatosis. All cases reported in the English literature were included. NGS is presented at all ages (range 8-68 years) with a median age of 42 years old. It shows female (62%) and Caucasian (80%) predominance. The most frequent symptoms are cough, fever, dyspnoea and chest pain. Extra-pulmonary involvement is found in one third of the cases, with ocular being the most common (12.5%). At imaging, multiple nodules (64.75%) or a solitary mass (20.49%) are found accompanied by mediastinal lymphadenopathy at one third of the cases. It can be clinically mistaken for malignancy as it is tumour-like, increases rapidly in size and it is hyperfixating in PET-SCAN. Histologically, NGS is defined by large areas of necrosis, well-formed granulomas and vascularitis. NGS is a disease often confounded clinically with malignancy or with sarcoidosis even histologically when all criteria are not strictly applied. This review provides NGS' characteristics and discusses its differential diagnosis form sarcoidosis, Wegener granulomatosis and tuberculosis. © 2017 John Wiley & Sons Ltd.

    In this report the authors describe a rare case of a fulminant, pyogenic, necrotizing infection of the spinal cord and brain. Necrotizing lesions of the brain and spinal cord are usually infectious in origin and are associated with high rates of morbidity and death. Although the pathogens responsible have been identified in a few instances, the causal factors remain unknown in many cases. An 11-year-old girl developed acute, rapidly progressive paraplegia with bladder involvement and sensory loss below T-10. She had been treated recently for a Staphylococcus aureus infection of the knee joint precipitated by a penetrating injury with organic matter in the aftermath of a cyclone. Although appropriate antibiotic therapy was instituted, the spinal cord infection progressed to involve the entire spinal cord, brainstem, and brain. This fulminant course was marked by a rapid deterioration in the patient's clinical condition, ultimately leading to her death. Magnetic resonance imaging demonstrated a previously undescribed pattern of longitudinal enhancement along the spinal cord, as well as the white matter tracts in the brainstem and brain. The possible route of spread of infection along the neuraxis is postulated to be the potential space along the white matter tracts. Treatment is not standardized due to the rarity of the condition.

    Full Text Available Acinar necrosis is the basic microscopic sign of acute necrotizing pancreatitis (ANP. Microcirculation disorder is one of the major factors in the pathogenesis and morphogenesis of ANP besides free radicals and damage of enzymatic origin. This study is dedicated to the description of microscopic changes in the pancreatic stroma in ANP, which leads to destruction of the exocrine pancreas with a putative mechanism of endocrine function preservation. This study has been carried out on histological samples of pancreas from 224 patients with ANP. Histological staining was performed with hematoxylin-eosin (H&E, Masson, Gomori methods, and PAS. Microscopy was performed with magnifications of 40×, 100×, and 400×. Vascular endothelial desquamation, stasis, and sludge are typical changes in microcirculation observed in early stages of ANP. Initially, parietal circular intravascular microthrombosis accompanied by endothelial desquamation as early as stromal swelling occurs with no detectable necrosis. Residual stroma appears between areas of necrosis and intact pancreatic tissue. Mucoid swelling is first seen in the perivascular spaces extending to the parenchyma and changing into fibrinoid imbibition causing further necrosis. Reticulin argyrophilic backbone surrounding the pancreatic acini and small ducts decompose. Pancreatic structures, which may be preserved in necrotic tissue, include nerves, major ducts, and Langerhans islets.

    Subacute necrotizing myelopathy(SNM) is a rare non-tumorous disease of spinal cord characterized by subacute clinical course of progressive neurological deterioration. We report MR findings of a patient with pathologically proved SNM. 1 case of pathologically proved subacute necrotizing myelopathy. The patients was a 56-year-old man with progressive motor weakness and sensory loss of the lower extremities, and urinary and fecal incontinence for 11 months. Spine MRI revealed diffuse enlargement of the thoracic spinal cord from T2 to T7 level. Signal intensity of the expanded spinal cord was isointense relative to normal cord on T1-weighted image and hyperintense on proton-density and T2-weighted images. On contrast enhanced T1-weighted image, there was diffuse homogeneous enhancement in the expanded cord lesion. MR demonstration of stable persistence of spinal cord lesion or atrophy over months or years with clinical findings of gradual progressive neurologic deterioration may be helpful in the diagnosis of SNM

    Full Text Available This report describes a case of necrotizing fasciitis presenting with septic shock due to an Aeromonas infection. The patient cut his foot while mowing the lawn and then spent time in a pool with black mold. He began feeling ill and developed swelling and a quarter-sized black area on his right lower extremity. Despite being hemodynamically unstable with systolic blood pressure in the low 70s, the patient was transferred to our facility from outside hospital 100 miles away. Upon arriving to facility, the patient appeared to be septic and the infected area of skin had grown. Irrigation and debridement were performed and appropriate antibiotic therapy was given; however, the patient subsequently died on hospital day 8. On review of the literature, cases of necrotizing fasciitis due to Aeromonas infection have been treated successfully with the aforementioned therapy; however, there is high mortality associated with these infections, many times related to a delayed diagnosis. Our patient also had multiple poor prognostic factors including hepatic dysfunction and immunosuppression.

    Orbital injury secondary to petroleum-based products is rare. We report the first case, to our knowledge, of a combined compressed air and chemical orbital injury, which mimicked necrotizing fasciitis. A 58-year-old man was repairing his motorcycle engine when a piston inadvertently fired, discharging compressed air and petroleum-based carburetor cleaner into his left eye. He developed surgical emphysema, skin necrosis, and a chemical cellulitis, causing an orbital compartment syndrome. He was treated initially with antibiotics and subsequently with intravenous steroid and orbital decompression surgery. There was almost complete recovery by 4 weeks postsurgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Petroleum-based products can cause severe skin irritation and necrosis. Compressed air injury can cause surgical emphysema. When these two mechanisms of injury are combined, the resulting orbitopathy and skin necrosis can mimic necrotizing fasciitis and cause diagnostic confusion. A favorable outcome is achievable with aggressive timely management. Copyright © 2014 Elsevier Inc. All rights reserved.

  5. Applying Adaptive Agricultural Management & Industrial Ecology Principles to Produce Lower- Carbon Ethanol from California Energy Beets

    Science.gov (United States)

    Alexiades, Anthy Maria

    The life cycle assessment of a proposed beet-to-ethanol pathway demonstrates how agricultural management and industrial ecology principles can be applied to reduce greenhouse gas emissions, minimize agrochemical inputs and waste, provide ecosystem services and yield a lower-carbon fuel from a highly land-use efficient, first-generation feedstock cultivated in California. Beets grown in California have unique potential as a biofuel feedstock. A mature agricultural product with well-developed supply chains, beet-sugar production in California has contracted over recent decades, leaving idle production capacity and forcing growers to seek other crops for use in rotation or find a new market for beets. California's Low Carbon Fuel Standard (LCFS) faces risk of steeply-rising compliance costs, as greenhouse gas reduction targets in the transportation sector were established assuming commercial volumes of lower-carbon fuels from second-generation feedstocks -- such as residues, waste, algae and cellulosic crops -- would be available by 2020. The expected shortfall of cellulosic ethanol has created an immediate need to develop lower-carbon fuels from readily available feedstocks using conventional conversion technologies. The life cycle carbon intensity of this ethanol pathway is less than 28 gCO2e/MJEthanol: a 72% reduction compared to gasoline and 19% lower than the most efficient corn ethanol pathway (34 gCO2e/MJ not including indirect land use change) approved under LCFS. The system relies primarily on waste-to-energy resources; nearly 18 gCO2e/MJ are avoided by using renewable heat and power generated from anaerobic digestion of fermentation stillage and gasification of orchard residues to meet 88% of the facility's steam demand. Co-products displace 2 gCO2e/MJ. Beet cultivation is the largest source of emissions, contributing 15 gCO 2e/MJ. The goal of the study is to explore opportunities to minimize carbon intensity of beet-ethanol and investigate the potential

    Depending on environmental factors fungal diseases of crops are often distributed heterogeneously in fields. Precision agriculture in plant protection implies a targeted fungicide application adjusted these field heterogeneities. Therefore an understanding of the spatial and temporal occurrence of pathogens is elementary. As shown in previous studies, remote sensing techniques can be used to detect and observe spectral anomalies in the field. In 2008, a sugar beet field site was observed at different growth stages of the crop using different remote sensing techniques. The experimental field site consisted of two treatments. One plot was sprayed with a fungicide to avoid fungal infections. In order to obtain sugar beet plants infected with foliar diseases the other plot was not sprayed. Remote sensing data were acquired from the high-resolution airborne hyperspectral imaging ROSIS in July 2008 at sugar beet growth stage 39 and from the HyMap sensor systems in August 2008 at sugar beet growth stage 45, respectively. Additionally hyperspectral signatures of diseased and non-diseased sugar beet plants were measured with a non-imaging hand held spectroradiometer at growth stage 49 in September. Ground truth data, in particular disease severity were collected at 50 sampling points in the field. Changes of reflection rates were related to disease severity increasing with time. Erysiphe betae causing powdery mildew was the most frequent leaf pathogen. A classification of healthy and diseased sugar beets in the field was possible by using hyperspectral vegetation indices calculated from canopy reflectance.

    Full Text Available Background and Objectives: Red beet extract concentrate can be used as a natural colorant in food products; however, destructive effects of thermal methods to produce juice concentrate decrease nutritional value in the final product. Materials and Methods: In this study, red beet extract was concentrated using osmotic distillation method, and the best pretreatment was evaluated to increase the efficiency of the concentration process. Also changes in some physicochemical properties such as betacyanins and betaxanthins contents, total phenolic compounds and antioxidant activity of red beet juice were evaluated by both the membrane and thermal concentration methods. Results: The results showed that the best concentration efficiency was obtained after pretreatment of the fresh juice with centrifugation at 1699 G for 17 min. Evaluation of the effect of both the membrane and thermal concentration processes on the physicochemical properties of juice showed that the membrane method did not change betacyanin and betaxanthin contents, total phenolic compounds, and antioxidant activity of the red beet extract. However, these properties decreased with the thermal concentration method by 26, 15, 11 and 13%, respectively. Conclusions: According to the results, osmotic distillation can produce red beet concentrate with more nutritional value than the concentrate produced with thermal method.

    Starch is the predominant storage compound in underground plant tissues like roots and tubers. An exception is sugar beet tap-root (Beta vulgaris ssp altissima) which exclusively stores sucrose. The underlying mechanism behind this divergent storage accumulation in sugar beet is currently not fully known. From the general presence of starch in roots and tubers it could be speculated that the lack in sugar beet tap-roots would originate from deficiency in pathways leading to starch. Therefore with emphasis on starch accumulation, we studied tap-roots of sugar beet using parsnip (Pastinaca sativa) as a comparator. Metabolic and structural analyses of sugar beet tap-root confirmed sucrose as the exclusive storage component. No starch granules could be detected in tap-roots of sugar beet or the wild ancestor sea beet (Beta vulgaris ssp. maritima). Analyses of parsnip showed that the main storage component was starch but tap-root tissue was also found to contain significant levels of sugars. Surprisingly, activities of four main starch biosynthetic enzymes, phosphoglucomutase, ADP-glucose pyrophosphorylase, starch synthase and starch branching enzyme, were similar in sugar beet and parsnip tap-roots. Transcriptional analysis confirmed expression of corresponding genes. Additionally, expression of genes involved in starch accumulation such as for plastidial hexose transportation and starch tuning functions could be determined in tap-roots of both plant species. Considering underground storage organs, sugar beet tap-root upholds a unique property in exclusively storing sucrose. Lack of starch also in the ancestor sea beet indicates an evolved trait of biological importance.Our findings in this study show that gene expression and enzymatic activity of main starch biosynthetic functions are present in sugar beet tap-root during storage accumulation. In view of this, the complete lack of starch in sugar beet tap-roots is enigmatic.

    2013-03-01

    Full Text Available Necrotizing fasciitis is a severe soft tissue infection, often life-threatening, characterized by necrosis of the subcutaneous and fascial tissue, which can be extended along the fascial plans, affecting the adjacent vessels, nerves and muscle tissue. The predisposing factors of the disease include: advanced age, immuno-compromised bodies, diabetes, chronic alcoholism and chronic smoking. Necrotizing fasciitis in head and neck segments is rare, usually with an odontogenic source of infection. In the early stages of evolution, a necrotizing fasciitis is difficult to differentiate from the non-necrotizing infection of the soft tissue. Due to its extremely severe evolution, an early presumptive diagnosis is necessary (based on clinical and imaging aspects, as well as a prompt aggressive surgery backed by an intensive care support. The clinical case of an immunocompromised patient admitted for a mouth floor diffuse suppuration, previously complicated with cervicothoracic necrotizing fasciitis with aggressive evolution, is discussed in the following.

    Full Text Available Introduction: About 0.1% of the population suffers from necrotizing ulcerative gingivitis, a disease of rapid progression and acute manifestation, which may progress to necrotizing ulcerative periodontitis and eventually to bone sequestration and loss of gingival tissue. Case report: A 21-year-old female patient undergoing orthodontic treatment for six months, diagnosed with necrotizing ulcerative gingivitis due to acute pain in the gingival tissue, spontaneous bleeding, halitosis and abundant plaque. The treatment was conservative and effective, obtaining total remission of the lesion after seven days and three months of postoperative follow-up. Conclusion: Today there are no epidemiological or clinical reports that support the relationship of necrotizing ulcerative gingivitis and orthodontic treatment. Prevention is critical to the success of the treatment, which is why the dentist should recognize the clinical features of necrotizing ulcerative gingivitis to raise awareness of its risks in the orthodontic patient.

    This paper presents a novel approach for identification of terahertz (THz) spectral of genetically modified organisms (GMOs) based on Hyper Sausage Neuron (HSN), and THz transmittance spectra of some typical transgenic sugar-beet samples are investigated to demonstrate its feasibility. Principal component analysis (PCA) is applied to extract features of the spectrum data, and instead of the original spectrum data, the feature signals are fed into the HSN pattern recognition, a new multiple weights neural network (MWNN). The experimental result shows that the HSN model not only can correctly classify different types of transgenic sugar-beets, but also can reject identity non similar samples in the same type. The proposed approach provides a new effective method for detection and identification of GMOs by using THz spectroscopy.

    The aim of the experiment was to establish the influence of biostimulation on the sugar beet seeds. The seeds came from the specialized breeding program energ'hill or were irradiated by the laser in two doses. The impact of the biostimulation was analyzed by determining the nitrate reductase activity and the nitrate, chlorophyll and carotenoids contents in leaves, as well as, the dry matter and sugar concentration in mature roots. The field experiment was established for two sugar beet cultivars. Biostimulation by irradiation and a special seed breeding program energ'hill had a positive influence on some examined parameters (particularly on nitrate reductase activity in Ruveta and in numerous cases on photosynthetic pigments in both cultivars). Regarding the dry matter accumulation and sugar concentration this impact was more favourable for Tiziana than for Ruveta cultivar.

    Full Text Available In the period 2001-2004, experiments were conducted in the region of Bačka (northern Serbia to assess the efficiency of insecticide treatment of sugar beet seeds in controlling soil pests (larvae of Elateridae family and reducing the damage caused by beet weevil (Bothynoderes punctiventris G e r m and flea beetle (Chaetocnema tibialis I l l i g. Several insecticides mostly systemic ones (carbofuran, thiamethoxam, fipronil, imidacloprid and clothianidin, and their combinations with pyrethroids in different doses were tested in field conditions. Stand density, percentages of plants damaged by B. punctiventris and C. tibialis, injury level and weight of juvenile plants served as parameters for evaluation of insecticide efficiency. Most of the insecticides applied to seeds provided a significantly better stand density compared with the untreated control. Because of their systemic action, imidacloprid, thiamethoxam and their mixtures with pyrethroids provided very good protection of juvenile plants from C. tibialis and in some cases from B. punctiventris.

    A suitable alternative to replace fossil fuels is the production of bioethanol from agroindustrial waste. Grape pomace is the most abundant residue in San Juan and sugar beet pomace could be important in the region. Solid-State Fermentation (SSF) is a technology that allows transforming agroindustrial waste into many valuable bioproducts, like ethanol. This work reports a laboratory scale SSF to obtain alcohol from grape and sugar beet pomace by means of Saccharomyces cerevisiae yeasts. The initial conditions of the culture medium were: sugars 16.5% (p/p); pH 4.5; humidity 68% (p/p). Cultures were inoculated with 10{sup 8} cells/g of pomace, and incubated in anaerobic environment, at 28 C, during 96 h. SSF showed ethanol maximum concentrations at 48 h and ethanol yield on sugars consumed was more than 82%. Yield attained creates expectation about the use of SSF to obtain fuel alcohol. (author)

    Lactic acid is an important chemical with various industrial applications, and it can be efficiently produced by fermentation, in which Bacillus coagulans strains present excellent performance. Betaine can promote lactic acid fermentation as an effective osmoprotectant. Here, positive effect of betaine on fermentation by B. coagulans is revealed. Betaine could enhance lactic acid production by protecting l-LDH activity and cell growth from osmotic inhibition, especially under high glucose concentrations and with poor organic nitrogen nutrients. The fermentation with 0.05 g/L betaine could produce 17.9% more lactic acid compared to the fermentation without betaine. Beet molasses, which is rich in sucrose and betaine, was utilized in a co-feeding fermentation and raised the productivity by 22%. The efficient lactic acid fermentation by B. coagulans is thus developed by using betaine and beet molasses.

  14. INVESTIGATION OF BACTERIOSTATIC PROPERTIES OF CHLORINATED COMPOUNDS FOR BEET-SUGAR INDUSTRY

    Directory of Open Access Journals (Sweden)

    N. G. Kulneva

    2014-01-01

    Full Text Available Summary. One of the major causes of decline in the quality of granulated sugar is bacterial contamination of sugar beet. This is due to the fact that the beet-sugar industry is a good object for the development of different groups of microorganisms. The main sources of infection of products of sugar manufacture can be soil, water, air, packaging, packaging materials, vehicles, clothing, equipment. The higher the beet contamination with the microorganisms, the more they decompose sucrose and secrete metabolic byproducts. In this regard, there is a need to reduce the negative impact of various groups of microorganisms and to minimize the loss of sucrose from decomposition. In accordance with the problem given the studies to determine the bacteriostatic properties of chlorinated compounds for sugar production were carried out. We used the cultivated fluid colonized with a pure culture of Leuconostoc mesenteroides and reagent treated as an object of study. In the experiments, we determined the accumulation of biomass of L. mesenteroides with nephelometric method by measuring the optical density of bacterial suspension. It was found out that after 24 hours of bacterial culturing the level of optical density in the control and active acidity were considerably higher compared with the sample treated with germicide. The number of microorganisms in the nutrient medium was determined by Vinogradsky-Shulgina-Brid’s. According to the study in the control is 1,7*10^16, in experiment with the introduction of the chlorinated compound it is 5,8*10^14. The experimental results show that the investigated chlorinated compound has bacteriostatic action against grampositive cocci saprophytic of L. mesenteroides and can be recommended for use in a sugar beet production.

    Premature flowering or bolting is an undesirable characteristic that causes severe sugar yield losses and interferes with harvesting. Vernalization is a prerequisite for the floral induction, achieved by exposure to low temperatures for 10-14 weeks. This process is also controlled by other environmental factors, such as long daylight photoperiods and a combination of genetic factors. The objective of this study was the identification of new genetic polymorphisms linked to bolting tendency in sugar beet. Two pollinators characterized by low and high bolting tendency were subjected to RAD-sequencing in order to detect discriminating SNPs between lines. 6,324 putative SNPs were identified. Of these, 192 were genotyped in a set of 19 pollinators, each comprising bolted and non-bolted individuals, for a total of 987 samples. Among the 192 candidate SNPs, the strongest overall association was found for SNP183 on chromosome 6 (p-value = 1.246 10(-13)). The association between SNP183 and bolting tendency was then confirmed in an independent population of 730 plants from 11 breeding lines (p-value = 0.0061). SNP183 is located in the intron of Bv_22330_orky, a sugar beet homolog of a matrix metalloproteinase (MMP) gene that could be implied in flowering in Arabidopsis thaliana. Our data support a significant association between an intronic SNP in the MMP gene located on chromosome 6 and the regulation of bolting tendency in sugar beet. The newly identified locus supports the polygenic nature of flowering control. The associated marker can be used to design SNP panels for the discrimination of bolters and non-bolters, to be used in sugar beet breeding programs for the development of improved germplasm with low bolting tendency.

    Growing interest in the replacement of synthetic food antioxidants by natural ones has fostered research on vegetable sources and screening of raw materials to identify new antioxidants. The food-processing industry generates substantial quantities of phenolic-rich by-products that could be valuable natural sources of antioxidants. In this study the antioxidant properties and total phenolic, flavonoid and flavonol contents of three industrial by-products, sugar beet pulp, sesame cake and potato peel, extracted with various solvents were examined. Since different antioxidant compounds have different mechanisms of action, several methods were used to assess the antioxidant efficacy of extracts. Among the six solvents tested, methanol gave the highest extract yield of potato peel and sugar beet pulp, while diethyl ether gave the highest extract yield of sesame cake. Methanol exhibited the highest extraction ability for phenolic compounds, with total phenolics amounting to 2.91, 1.79 and 0.81 mg gallic acid equivalent g(-1) dry weight in potato peel, sugar beet pulp and sesame cake extracts respectively, and also showed the strongest antioxidant capacity in the three assays used. All three methods proved that potato peel extract had the highest antioxidant activity owing to its high content of phenolic compounds and flavonoids. On the basis of the results obtained, potato peel, sugar beet pulp and sesame cake extracts could serve as natural antioxidants owing to their significant antioxidant activity. Therefore they could be used as preservative ingredients in the food and/or pharmaceutical industries. (c) 2009 Society of Chemical Industry.

    Full Text Available Sugar beet is one of strategic products to supply sugar in water limited areas of Iran. Thus, proper managements to supply enouph water in production of sugar beet is very important. To evaluate the effects of some anti stress substances like salicylic acid, tyuful and glycine to irritigate the effect of early water deficit on suger beet, an experiment based on randomized complete block design with three replications was carried out at the Research Farm of Fariman Sugar Factory in 2013. Treatments consisted of control (without using anti stress substances, with three concentration of salicylic acid (0.1, 0.5, and 1 mM, tyuful with three concentration (0.5, 1 and 1.5 liter per thousand and glycine with three concentration (1, 2 and 3 liters per thousand. The results showed that the effects of anti-stress materials significantly affected the sugar content, root yield, white sugar yield and harmful nitrogen. Highest sugar content (15.65%, root yield (83.82 t.ha-1 and white sugar percentage (11.15% were obtained by using tyuful 1.5 lit/1000. While, the lowest levels of these characters were obtained from control (not using anti stress substances. Maximum harmful nitrogen was produced in control treatment (4.38 and highest level of alkalinity with mean of 3.49 was observed by using 3 lit/1000 of glycine. Our results showed that all of the anti stress substances had positive effects on sugar beet under drought stress condition.

    Insulin resistance and obesity are characterized by low nitric oxide (NO) bioavailability. Insulin sensitivity is improved with stimulation of NO generating pathways. Consumption of dietary nitrate (NO 3 - ) increases NO formation, via NO 3 - reduction to nitrite (NO 2 - ) by oral bacteria. We hypothesized that acute dietary nitrate (beet juice) ingestion improves insulin sensitivity in obese but not in nonobese adults. 12 nonobese (body mass index: 26.3 ± 0.8 kg/m 2 (mean ± SE)) and 10 obese adults (34.0 ± 0.8 kg/m 2 ) ingested beet juice, supplemented with 25 g of glucose (carbohydrate load: 75 g), with and without prior use of antibacterial mouthwash to inhibit NO 3 - reduction to NO 2 - . Blood glucose concentrations after beet juice and glucose ingestion were greater in obese compared with nonobese adults at 60 and 90 minutes ( P = 0.004). Insulin sensitivity, as represented by the Matsuda Index (where higher values reflect greater insulin sensitivity), was lower in obese compared with nonobese adults ( P = 0.009). Antibacterial mouthwash rinsing decreased insulin sensitivity in obese (5.7 ± 0.7 versus 4.9 ± 0.6) but not in nonobese (8.1 ± 1.0 versus 8.9 ± 0.9) adults ( P = 0.048). In conclusion, insulin sensitivity was improved in obese but not in nonobese adults following coingestion of beet juice and glucose when oral bacteria nitrate reduction was not inhibited. Obese adults may benefit from ingestion of healthy nitrate-rich foods during meals.

    As part of a long-term strategy toward renewable feedstock, a feasibility study into options for the production of bioethylene by integrating the sugar beet-to-ethanol-to-ethylene value chain. Seven business cases were studied and tested for actual economic feasibility of alternative sugar-to-ethanol-to-ethylene routes in comparison to fossil-fuel alternatives. An elaborate model was developed to assess the relevant operational and financial aspects of each business case. The calculations indicate that bioethylene from sugar beet is not commercially viable under current market conditions. In light of expected global energy and feedstock prices it is also reasonable to expect that this will not change in the near future. To consider biorenewable sources as starting material, they need to be low in cost (compared to sugar beets) and also require less capital and energy-intensive methods for the conversion to chemicals. In general, European sugar prices will be too high for many chemical applications. Future efforts for in sugar-to-chemicals routes should, therefore, focus on integrated process routes and process intensification and/or on products that contain a significant part of the original carbohydrate backbone.

    Sugar beet root maggot (SBRM, Tetanops myopaeformis von Röder) is a major but poorly understood insect pest of sugar beet (Beta vulgaris L.). The molecular mechanisms underlying plant defense responses are well documented, however, little information is available about complementary mechanisms for insect adaptive responses to overcome host resistance. To date, no studies have been published on SBRM gene expression profiling. Suppressive subtractive hybridization (SSH) generated more than 300 SBRM ESTs differentially expressed in the interaction of the pest with a moderately resistant (F1016) and a susceptible (F1010) sugar beet line. Blast2GO v. 3.2 search indicated that over 40% of the differentially expressed genes had known functions, primarily driven by fruit fly D. melanogaster genes. Expression patterns of 18 selected EST clones were confirmed by RT-PCR analysis. Gene Ontology (GO) analysis predicted a dominance of metabolic and catalytic genes involved in the interaction of SBRM with its host. SBRM genes functioning during development, regulation, cellular process, signaling and under stress conditions were annotated. SBRM genes that were common or unique in response to resistant or susceptible interactions with the host were identified and their possible roles in insect responses to the host are discussed. © Published 2016.

    The aim of this study was to develop a system dynamics model for computation of yields and to investigate the dependency of yields on some major climatic parameters, i.e. temperature and rainfall, for Beta vulgaris subsp. (sugar beet crops) under future climate change scenarios. A system dynamics model was developed which takes account of the effects of rainfall and temperature on sugar beet yields under limited irrigation conditions. A relationship was also developed between the seasonal evapotranspiration and seasonal growing degree days for sugar beet crops. The proposed model was set to run for the present time period of 1993-2012 and for the future period 2013-2040 for Lethbridge region (Alberta, Canada). The model provides sugar beet yields on a yearly basis which are comparable to the present field data. It was found that the future average yield will be increased at about 14% with respect to the present average yield. The proposed model can help to improve the understanding of soil water conditions and irrigation water requirements of an area under certain climatic conditions and can be used for future prediction of yields for any crops in any region (with the required information to be provided). The developed system dynamics model can be used as a supporting tool for decision making, for improvement of agricultural management practice of any region. © 2014 Society of Chemical Industry.

    Full Text Available In the present investigation, aimed at obtaining beet haploids from anthers, the effect of mineral media, potato and sugar beet extract and p-fluorophenylalanine (PFP in combination with growth substances was tested. Nutrient-starved plants as anther-donors, anther-starvation, cold treatment and photoperiod were also analysed. On all mineral media the anthers produced callus and roots; however, the percentage depended on the combination of growth substances used. The best medium for differentiation was that of Linsmaier and Skoog with 25 µM zeatin or 6-(3-methyl-2-butenylaminopurine with 5 µM naphthalene-l-acetic acid (25.5%. The addition of PFP caused an increase in the percentage of anther differentiation (41.6%. Besides callus and roots on one of the anthers (in ca. 140000 tested, vegetative buds were formed from which numerous plants were obtained (2n. Plant and anther nutrient starvation did not improve the anther response to differentiation, nor did it induce haploid development, similarly as cold treatment of inflorescences or isolated anthers. The anthers of wild species showed lower ability to differentiate than those of sugar or fodder beets. Cytological analyses showed formation of multicellular structures until ca. the 12-th day of anther culture; afterwards, they degenerated.

    Soil compaction is a critical issue in agriculture having a significant influence on crop growth. Sugar beet (Beta vulgaris L.) is accounted as a crop susceptible to compaction. Reduction of leaf area, final yield, and root quality parameters are reported in compacted soils. The most obvious visual indicator of topsoil compaction is root depth affected by agricultural tractor and machinery traffic up on the soil. Such indicators are mainly correlated to initial soil condition, tyre features, and number of passages. Monitoring and controlling frequency and position of machine traffic across the field, in such a way that passages are completed on specific, well-defined tracks, can assist with minimization of compaction effects on soil. The objective of the present work was to analyze the subsoil compaction during the growing period of sugar beet with different farming approaches including controlled traffic passages and random traffic. To this end, tests were carried out following each agro technical operation using penetrometer readings in order to monitor the state of cone-index after each step. In addition, at the harvesting time, root quality parameters were analyzed with particular attention to length and regularity of the taproot, total length, circumference, mass, and above-ground biomass. Such parameters were usefully implemented in order to evaluate the effects of controlled traffic passages compared to the random traffic in a cultivation of sugar beet. Results highlight how an increase in crop yield, derived from samples monitored, higher than 10% can be expected with implementation of a careful traffic management.

    Full Text Available Micronutrients have an important role in growth and yield of plants. This investigatin was carried out to evaluate effect of foliar applications of three micronutrients (Fe, Mn and Zn at different times (4-6 and 8-10 leaf stage with three replication on sugar beet. Based on results obtained all of the micronutrients used increased sugar beet sugar yield. Highest root yield was obtained by using 9 % of micronutrients at 4-6 leaf stage, but other concentrations did not have any effect on sugar beet yield. All of the three micronutrient concentrations increased root yield significantly. Application of 6% concentration increased root yield by 15.6 %. Mn application did not have any effect on sugar yield. 9 % concentration of Zn foliar application increased sugar yield by 16.4 %, and application of 6 and 9% of Fe increased sugar yield by 18.6 and 36 % respectively. Sugar percent did not changed by Mn application, but high concentrations of Fe and Zn at 8-10 leaf stage increased it. Highest increase in sugar percent obtained by using Fe 9 % foliar appliction. Because of economical importance of sugar and root yield, foliar application of 9 % of Fe and Zn at 8-10 leaf stage will be suitable.

  18. Noninvasive presymptomatic detection of Cercospora beticola infection and identification of early metabolic responses in sugar beet

    Directory of Open Access Journals (Sweden)

    Hans-Peter Mock

    2016-09-01

    Full Text Available Cercospora beticola is an economically significant fungal pathogen of sugar beet, and is the causative pathogen of Cercospora leaf spot. Selected host genotypes with contrasting degree of susceptibility to the disease have been exploited to characterize the patterns of metabolite responses to fungal infection, and to devise a pre-symptomatic, non-invasive method of detecting the presence of the pathogen. Sugar beet genotypes were analyzed for metabolite profiles and hyperspectral signatures. Correlation of data matrices from both approaches facilitated identification of candidates for metabolic markers. Hyperspectral imaging was highly predictive with a classification accuracy of 98.5-99.9 % in detecting C. beticola. Metabolite analysis revealed metabolites altered by the host as part of a successful defence response: these were L-DOPA, 12-hydroxyjasmonic acid 12-O-β-D-glucoside, pantothenic acid and 5-O-feruloylquinic acid. The accumulation of glucosylvitexin in the resistant cultivar suggests it acts as a constitutively-produced protectant. The study establishes a proof-of-concept for an unbiased, presymptomatic and non-invasive detection system for the presence of C. beticola. The test needs to be validated with a larger set of genotypes, to be scalable to the level of a crop improvement program, aiming to speed up the selection for resistant cultivars of sugar beet. Untargeted metabolic profiling is a valuable tool to identify metabolites which correlate with hyperspectral data.

By increasing input of N from FYM application into the soil causes an increases of α- amino nitrogen content in root, which in consequence causes a decreases the sugar content (negative correlation r= -0.8659+. The application of straw instead FYM of analogues treatments caused significant decrease (straw versus FYM and highly significant decrease (straw plus N fertilizers versus FYM plus N fertilizers of α-amino nitrogen content in sugar beet root living the productive parameters unchanged. The content of α-amino nitrogen in root of sugar beet indicate an environmentally friendly management practices with causal relation to water protection from nitrate.
