    Full Text Available Fragments of viral cDNA containing the coat protein gene of beet necrotic yellow vein virus were cloned in plant transformation vector pCAMBIA3301M with the bar gene as selectable marker. 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.

    Full Text Available During 2008 crop season, an outbreak of severe yellow mosaic disease on yard long bean (Vigna unguiculata subsp. Sesquipedalis occurred in several farmers’ fields in West Java. Yard long bean var. Parade inoculated manually with extracts from symptomatic leaves showed the symptoms indicating the presence of virus. Symptomatic leaf samples tested positive in enzyme linked immunosorbent assay (ELISA with antibodies to group specific Potyvirus and Cucumber mosaic virus (CMV. Total RNA derived from symptomatic leaves was subjected to reverse transcription-polymerase chain reaction (RT-PCR using primers specific to the cylindrical inclusion (CI protein of potyviruses and CMV coat protein (CP specific primers. Pair wise comparison of sequences obtained from cloned RT-PCR products with corresponding nucleotide sequences in the GenBank confirmed the presence of Bean common mosaic virus strain Blackeye (BCMV-BlC and CMV in the symptomatic beans. Sequences of BCMV and CMV isolates from the beans showed maximum nucleotide sequence identities (92-97% and (90%, respectively with BCMV-BIC and CMV isolates from Taiwan. Each virus isolate also clustered closely with corresponding isolates from Taiwan in a phylogenetic analyses. These results provide first evidence of the occurrence of multiple infection of BCMV-BIC and CMV in the yard long been from Bogor, West Java.

    1. The effect of three different levels of dietary trypsin inhibitor activity (achieved by varying the amount of non-toasted full fat soya bean in replacement for toasted full fat soya bean) on the incidence of spontaneously-occurring sub-clinical necrotic enteritis (NE) in broiler chickens was compared. A fourth dietary treatment compared the effect of a diet that used potato protein concentrate as the major protein source. The determined trypsin inhibitor activity increased with the increasing content of non-toasted soya bean: 1·90, 6·21, 8·46 and 3·72 mg/g for the three soya bean diets (0, 100 and 200 g of non-toasted soya bean/kg) and the potato protein diet respectively. 2. Although increasing amounts of the non-toasted full-fat soya bean increased the feed intakes of the birds, there was a marked reduction in protein digestibility, weight gain and feed conversion efficiency. 3. There was a linear increase in sub-clinical NE lesions in the duodenum, jejunum, mid small intestine and ileum with increasing non-toasted soya bean. Caecal Clostridium perfringens counts increased with the increasing dietary content of non-toasted soya bean. Serum α-toxin antibodies were higher in the birds fed the 200 g non-toasted soya bean/kg diet compared with the other diets. 4. The results demonstrated that variation in the amount of non-toasted dietary soya bean not only affects growth performance of broilers but also affects the incidence of sub-clinical necrotic enteritis in the flock. Ensuring the lowest possible trypsin-inhibitor activity in soya bean samples is a valuable tool to improve the health and welfare of birds and in reducing the financial losses from this disease.

    Nowadays, legume plants have been considered not only a source of valuable proteins necessary for the proper functioning and growth of the body but also a source of bioactive compounds such as bioactive peptides, that may be beneficial to human health and protect against negative change in food. The aim of this study was to investigate the effect of heat treatment on the release of antioxidant peptides obtained by hydrolysis of the yellow string beans protein. The antioxidant properties of the hydrolysates were evaluated through free radical scavenging activities (DPPH and ABTS) and inhibition of iron activities (chelation of Fe2+). The results show that the heat treatment had influence on both increased peptides content and antioxidant activity after pepsin hydrolysis of string bean protein. The peptides content after protein hydrolysis derived from raw and heat treated beans were noted 2.10 and 2.50 mg·ml-1, respectively. The hydrolysates obtained from raw (PHR) and heat treated (PHT) beans showed better antioxidant properties than protein isolates (PIR and PIT). Moreover, the hydrolysates obtained from heat treated beans showed the higher ability to scavenge DPPH• (46.12%) and ABTS+• (92.32%) than obtained from raw beans (38.02% and 88.24%, correspondingly). The IC50 value for Fe2+ chelating ability for pepsin hydrolysates obtained from raw and heat treatment beans were noted 0.81 and 0.19 mg·ml-1, respectively. In conclusion, the results of this study showed that the heat treatment string beans caused increase in the antioxidant activities of peptide-rich hydrolysates.

    Full Text Available We investigated the protective effects of a viral vector based on an Apple latent spherical virus (ALSV harboring a segment of the Bean yellow mosaic virus (BYMV genome against mosaic diseases in pea, broad bean, and eustoma plants caused by BYMV infection. In pea plants pre-inoculated with the ALSV vaccine and challenge inoculated with BYMV expressing green fluorescence protein, BYMV multiplication occurred in inoculated leaves, but was markedly inhibited in the upper leaves. No mosaic symptoms due to BYMV infection were observed in the challenged plants pre-inoculated with the ALSV vaccine. Simultaneous inoculation with the ALSV vaccine and BYMV also prevented mosaic symptoms in broad bean and eustoma plants, and BYMV accumulation was strongly inhibited in the upper leaves of plants treated with the ALSV vaccine. Pea and eustoma plants were pre-inoculated with BYMV followed by inoculation with the ALSV vaccine to investigate the curative effects of the ALSV vaccine. In both plant species, recovery from mosaic symptoms was observed in upper leaves and BYMV accumulation was inhibited in leaves developing post-ALSV vaccination. These results show that ALSV vaccination not only prevents mosaic diseases in pea, broad bean, and eustoma, but that it is also effective in curing these diseases.

    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 Abstract Background Plasmodiophorids and chytrids are zoosporic parasites of algae and land plant and are distributed worldwide. There are 35 species belonging to the order Plasmodiophorales and three species, Polymyxa betae, P. graminis, and Spongospora subterranea, are plant viral vectors. Plasmodiophorid transmitted viruses are positive strand RNA viruses belonging to five genera. Beet necrotic yellow vein virus (BNYVV and its vector, P. betae, are the causal agents for rhizomania. Results Evidence of BNYVV replication and movement proteins associating with P. betae resting spores was initially obtained using immunofluorescence labeling and well characterized antisera to each of the BNYVV proteins. Root cross sections were further examined using immunogold labeling and electron microscopy. BNYVV proteins translated from each of the four genomic and subgenomic RNAs accumulate inside P. betae resting spores and zoospores. Statistical analysis was used to determine if immunolabelling detected viral proteins in specific subcellular domains and at a level greater than in control samples. Conclusion Virus-like particles were detected in zoosporangia. Association of BNYVV replication and movement proteins with sporangial and sporogenic stages of P. betae suggest that BNYVV resides inside its vector during more than one life cycle stage. These data suggest that P. betae might be a host as well as a vector for BNYVV

    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.

    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.

    1. An experiment was conducted to compare and explain the incidence of spontaneously occurring subclinical necrotic enteritis in broiler chickens that were fed on two practical broiler diets that differed in the major protein concentrates (soya bean meal or potato protein concentrates) and examine the relationships between the severity of the disease and the growth performance and physiological responses of the chickens. 2. A total of 840, 20-d-old birds were randomly allocated to 12 pens. Two maize-based nutritionally complete diets that either contained some potato protein or soya bean meal as the major protein supplement were fed for 16 d. Twelve birds were randomly sampled from each pen at the end of the feeding period and their blood sampled and intestinal tracts and livers dissected. 3. The birds fed on the potato protein diet had a significantly 7·7% lower feed intake and a significantly 7·8% lower growth rate compared with the birds fed on the soya-based diet. There were no significant differences in feed conversion efficiency or mortality. There were no differences in the determined apparent metabolisable energy concentrations, however, the apparent dry matter digestibility of the potato protein diet was significantly higher than that of the soya based diet and the apparent crude protein digestibility of the potato protein diet was significantly lower. 4. A significantly higher alpha toxin antibody titre was found in the birds fed on the potato protein diet compared with those fed on the soya protein diet. There was a significantly increased incidence of hepatic lesions in the birds fed on the potato protein diet compared with the birds fed on the soya diet. The mean incidence of intestinal necroses tended to be greater in the birds fed on the potato protein diet (23·6%) compared with the birds fed on the soya-based diet (15·3%). 5. There was a significant linear relationship between ileal digesta sialic acid concentration and serum alpha toxin

    Expression of recombinant vaccine antigens and monoclonal antibodies using plant viral vectors has developed extensively during the past several years. The approach benefits from high yields of recombinant protein obtained within days after transient delivery of viral vectors to leaves of Nicotiana benthamiana, a tobacco relative. Modified viral genomes of both RNA and DNA viruses have been created. Geminiviruses such as bean yellow dwarf virus (BeYDV) have a small, single stranded DNA genome that replicates in the nucleus of an infected plant cell, using the cellular DNA synthesis apparatus and a virus-encoded replication initiator protein (Rep). BeYDV-derived expression vectors contain deletions of the viral genes encoding coat and movement proteins and insertion of an expression cassette for a protein of interest. Delivery of the geminiviral vector to leaf cells via Agrobacterium-mediated delivery produces very high levels of recombinant DNA that can act as a transcription template, yielding high levels of mRNA for the protein of interest. Several vaccine antigens, including Norwalk virus capsid protein and hepatitis B core antigen, were expressed using the BeYDV vector at levels up to 1 mg per g of leaf mass. BeYDV replicons can be stacked in the same vector molecule by linking them in tandem, which enables production of multi-subunit proteins like monoclonal antibody (mAb) heavy and light chains. The protective mAb 6D8 against Ebola virus was produced at 0.5 mg per g of leaf mass. Multi-replicon vectors could be conveniently used to produce protein complexes, e.g. virus-like particles that require two or more subunits.

  19. 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.

  20. Deep sequencing-based transcriptome profiling reveals comprehensive insights into the responses of Nicotiana benthamiana to beet necrotic yellow vein virus infections containing or lacking RNA4.

    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.

Essas inclusões não foram encontradas no pólen ou no óvulo de feijoeiros infetados. Como o vírus do mosaico comum do feijoeiro é transmitido pelo pólen, sugere-se que êle ocorre nestas células em concentração muito baixa, ou mesmo na forma de ácido nucléico.Two types of cytoplasmic inclusions were observed in leaf and root tissues of host plants infected with the common and yellow bean mosaic viruses: (1 filamentous inclusions considered as an aggregate of virus particles and (2 lamellar inclusions which appeared with varied configurations that represent sections at different angles of the same cylindrical structure. No type of inclusion or virus particle was seen in pollen and ovule from bean plants infected with each of the two viruses. Since, however, the common bean mosaic virus is transmitted through the pollen it is suggested that it occurs in very low concentration in this structure or else as viral nucleic acid.

    A multiplex reverse transcription polymerase chain reaction (RT-PCR) assay was developed to simultaneously detect bean common mosaic virus (BCMV), bean common mosaic necrotic virus (BCMNV), and bean golden yellow mosaic virus (BGYMV) from common bean leaves dried with silica gel using a single total nucleic acid extraction cetyl trimethyl ammonium bromide (CTAB) method. A mixture of five specific primers was used to amplify three distinct fragments corresponding to 272 bp from the AC1 gene of BGYMV as well as 469 bp and 746 bp from the CP gene of BCMV and BCMNV, respectively. The three viruses were detected in a single plant or in a bulk of five plants. The multiplex RT-PCR was successfully applied to detect these three viruses from 187 field samples collected from 23 municipalities from the states of Guanajuato, Nayarit and Jalisco, Mexico. Rates of single infections were 14/187 (7.5%), 41/187 (21.9%), and 35/187 (18.7%), for BGYMV, BCMV, and BCMNV, respectively; 29/187 (15.5%) samples were co-infected with two of these viruses and 10/187 (5.3%) with the three viruses. This multiplex RT-PCR assay is a simple, rapid, sensitive, and cost-effective method for detecting these viruses in the common bean and can be used for routine molecular diagnosis and epidemiological studies.

    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

    Full Text Available Phani Kiran Yajamanyam,1 Shree Vishna Rasiah,1 Andrew K Ewer1,2 1Neonatal Unit, Birmingham Women's Hospital NHS Foundation Trust, 2School of Clinical and Experimental Medicine, University of Birmingham, Birmingham, UK Abstract: Necrotizing enterocolitis is the most common gastrointestinal emergency in neonates, particularly in those born very preterm. 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.

    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.

    The effects of boiling and steaming processes on the antiproliferative and cellular antioxidant properties, as well as phytochemicals, of two types of common beans (pinto and black beans) and two types of soybeans (yellow and black) were investigated. All thermal-processing methods caused significant (pbean types (except for TPC values in pressure-steamed yellow soybeans) as compared to those of the raw beans. All types of uncooked raw beans exhibited cellular antioxidant activities (CAA) in dose-dependent manners. Black soybeans exhibited the greatest CAA, followed by black beans, pinto beans and yellow soybeans. The CAA of cooked beans were generally diminished or eliminated by thermal processing. The hydrophilic extracts from raw pinto beans, black beans and black soybeans exhibited antiproliferation capacities against human gastric (AGS) and colorectal (SW480) cancer cells in dose-dependent manners. The raw yellow soybeans exhibited dose-dependent antiproliferation activities against the SW480 cells. Most of the cooked beans lost their antiproliferation capacities as observed in the raw beans. These results indicate that different processing methods may have various effects on phytochemical profiles and bioactivities. Overall, thermal processing caused a significant reduction of the health-promotion effects of beans. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Mung beans (Vigna radiata [L] Wilczek) purchased from a Spanish company as "green soybeans", showed a different phenolic composition than yellow soybeans (Glycine max cv. Merit). Isoflavones were predominant in yellow soybeans, whereas they were completely absent in the green seeds on which flavanones were predominant. In order to enhance their health benefits, both types of bean were subjected to technological processes, such as soaking and fermentation. Soaking increased malonyl glucoside isoflavone extraction in yellow beans and produced an increase in apigenin derivatives in the green beans. Lactobacillus plantarum CECT 748 T fermentation produced an increase in the bioactivity of both beans since a conversion of glycosylated isoflavones into bioactive aglycones and an increase of the bioactive vitexin was observed in yellow and green beans, respectively. In spite of potential consumer confusion, since soybean and "green soybean" are different legumes, the health benefits of both beans were enhanced by lactic fermentation.

    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

    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)

    Full Text Available The aim of this study was to investigate germination of good bean seed of the variety Galeb and the bad bean seed of the same variety. We were also interested in germination of bean and snap bean seed damaged by grain weevil, and in germination of the seed treated by freezing which was aimed at controlling grain weevil by cold. We also recorded the differences between bean and snap bean seed, which was or was not treated by freezing in laboratory conditions. This investigation was carried out by applying the two factorial block system. The obtained results were evaluated by the variance analysis and x2 test These results suggest that the bean seed of a bad fraction had low levels of germination, but still it was present. Although the seed of good appearance was carefully selected, germination was slightly lower than it should have been. The seed with the large amount of grain weevils performed a high level germination in laboratory conditions. There were no differences in germination between the seed injured by grain weevil either in beans or in snap beans. As for the seed treated or untreated by freezing, there also were no differences between beans and snap beans. .

    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.

    Dry beans (Phaseolus vulgaris L.) are a nutrient-dense food rich in protein and micronutrients. Despite their nutritional benefits, long cooking times limit the consumption of dry beans worldwide, especially in nations where fuelwood for cooking is often expensive or scarce. This study evaluated the nutritive value of 12 dry edible bean lines that vary for cooking time (20-89 min) from four market classes (yellow, cranberry, light red kidney, and red mottled) of economic importance in bean-consuming regions of Africa and the Americas. When compared to their slower cooking counterparts within each market class, fast-cooking dry beans retain more protein and minerals while maintaining similar starch and fiber densities when fully cooked. For example, some of the highest protein and mineral retention values were measured in the fast-cooking yellow bean cultivar Cebo Cela, which offered 20% more protein, 10% more iron, and 10% more zinc with each serving when compared with Canario, a slow-cooking yellow bean that requires twice the cooking time to become palatable. A Caco-2 cell culture model also revealed the bioavailability of iron is significantly higher in faster cooking entries (r = -0.537, P = 0.009) as compared to slower cooking entries in the same market class. These findings suggest that fast-cooking bean varieties have improved nutritive value through greater nutrient retention and improved iron bioavailability.

    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.

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.)

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

    Common bean (Phaseolus vulgaris L.) is an important legume with high nutritional value. In Nicaragua, certified healthy seeds of local bean varieties are not available, and seedborne fungi have gained little attention. Here, were surveyed seedborne pathogenic fungi in an important local bean cultivar, 'INTA Rojo'. Beans grown in the four main production areas in Nicaragua (Boaco, Carazo, Estelí, Matagalpa) for future use as seed stock were sampled from four seed storehouses and six seed lots. A total of 133 fungal strains were isolated from surface-sterilized beans and inoculated to healthy lima beans (Phaseolus lunatus) under controlled conditions. Eighty-seven isolates caused symptoms of varying severity in the seedlings, including discoloration, necrotic lesions, cankers, rot, and lethal necrosis. Pathogenic isolates were divided into eight phenotypically distinguishable groups based on morphology and growth characteristics on artificial growth medium, and further identified by analysis of the internal transcribed spacer sequences (ITS1 and ITS2) of the ribosomal RNA genes. The pathogenic isolates belonged to eight genera. Fusarium spp. (F. chlamydosporum, F. equiseti, F. incarnatum), Lasiodiplodia theobromae, Macrophomina phaseolina, and Penicillium citrinum were the most damaging and common fungi found in the seed lots. Furthermore, Corynespora cassiicola, Colletotrichum capsisi, Colletotrichum gloeosporioides, Aspergillus flavus, and Diaporthe sp. (Phomopsis) were seedborne in cultivar 'INTA Rojo' and found to be pathogenic to bean seedlings. This study reveals, for the first time, many seedborne pathogenic fungi in beans in Nicaragua; furthermore, prior to this study, little information was available concerning F. equiseti, F. incarnatum, L. theobromae, C. cassiicola, and Diaporthe spp. as seedborne pathogens of common bean. Our results lay the basis for developing diagnostic tools for seed health inspection and for further study of the epidemiology

    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.

One of control effort way by utilizing antiviral substances of plant origin. The research was done to select and test the effectiveness of plant extracts in suppressing BCMV infection on yard long bean. Twenty two plant extracts were selected by (1 spraying the crude extract to Chenopodium amaranticolor leaves, then plant inoculated by BCMV 1 hour after spraying, and (2 mixturing the crude extract with sap containing BCMV, then inoculated mechanically to C. amaranticolor.  Local necrotic lesion  number and inhibition percentage are measured. All plant extract treatments were able to reduce Necrotic lokal lesion  formation significantly  compared to untreatment control. Further, fifteen plant extracts were selected to test their effectiveness in controlling BCMV on yard long bean in green house trial. The results showed that except geranium and red ginger treatment, other extract treatments were able to reduce significantly the disease incidence and severity, symptoms, and  BCMV titer, respectively. Among tested extracts, Bougainvillea spectabilis, Mirabilis jalapa, and Celosia cristata are the most effective crude extracts in suppressing BCMV infection.

    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.

  13. Characterization resistance mechanisms in faba bean (Vicia faba against broomrape species (Orobanche and Phelipanche spp.

    Directory of Open Access Journals (Sweden)

    Diego Rubiales

    2016-11-01

    Full Text Available Faba bean (Vicia faba production in Mediterranean and Near East agriculture is severely constrained by broomrape infection. The most widely distributed broomrape species affecting faba bean is Orobanche crenata, although O. foetida and Phelipanche aegyptiaca are of local importance. Only moderately resistant cultivars are available to farmers. Rizotrons studies allowed the dissection of resistance components in faba bean accessions against the very infective species O. crenata, O. foetida var. broteri and P. aegyptiaca, and to the inappropriate P. ramosa and O. foetida var. foetida. Results confirm that some levels of incomplete resistance are available, resulting in a reduced number of broomrape tubercles successfully formed per faba bean plant. Interestingly, the intermediate levels of resistance of cv. Baraca were operative against all broomrape populations and species studied, confirming previous reports on the stability of resistance of Baraca in field trials in different countries. Low induction of seed germination played a major role in the resistance against the inappropriate O. foetida var. foetida but not against the also inappropriate P. ramosa, neither to the infective species O. crenata, O. foetida var. broteri or P. aegyptiaca. Negative tropism of germinated seeds with radicles growing away from faba bean roots was marked for both inappropriate species but was not observed in any of the infective species. Also, a proportion of radicles that had successfully contacted faba bean roots became necrotic, failing in starting tubercle development, particularly frequent for the two inappropriate species. Such necrosis was significant also on radicles contacting resistant faba bean accessions, being particularly relevant for Spanish O. crenata population, and lower although still significant in some accessions against Syrian O. crenata and P. aegytiaca, suggesting that this might also be an operative mechanism to be selected and further

    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.

    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

    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.

    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.

  19. Evaluation of rotational effect of bean in large-scale rice-bean rotation using satellite remote sensing experiment

    Science.gov (United States)

    Sun, Ling; Zhu, Zesheng

    2017-06-01

    A large-scale rice-bean rotation experiment was examined to analyze the rotational effect of bean by using the normalized difference vegetation index (NDVI) of bean on satellite remote sensing image. The experiment was undertaken at Rudong County of China from 2009 to 2010. The difference between the bean NDVIs of bean-bean monoculture and rice-bean rotation was used to evaluate the rotational effect of bean. The results show that the NDVI of rice-bean rotation is obviously larger than one of bean-bean monoculture in such large-scale experiment. Thus, we have also found the compelling evidence that the bean yield of rice-bean rotation is greater than the bean yield of bean-bean monoculture.

    Full Text Available During past few years a symptoms of plum and cherry bud necrosis were observed in some regions with significant cherry production in Serbia. Gram negative, fluorescent, oxidative bacterial strains were isolated from the margin of necrotic tissue. All investigated strains are levan and HR positive, while negative results are recorded in oxidase, pectinase and arginin dihydrolase tests (LOPAT+---+. Symptoms similar to those observed in natural infection were obtained after artificial inoculation of cherry leaf scares and dormant one year old cherry shoots. Investigated strains as well as reference strain of P. syringae pv. morsprunorum cause the superficial necrosis on artificially inoculated immature cherry fruits, but negative results were recorded in immature pear and lemon fruit tests as well as syringae leaves and bean pods. Gelatin and aesculin tests were negative and tyrosinase and tartrate were positive. Investigated strains isolated from necrotic cherry buds had identical REP-PCR pattern with reference strain of P. syringae pv. morsprunorum. On the basis of obtained results, it was concluded that this bacterium is causal agent of cherry trees bud necrosis in Serbia. [Projekat Ministarstva nauke Republike Srbije, br. 31018 i br. 173026

    1998-02-01

    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.

    The author has acquired a yellow laser with the specific wavelength of 589 nm. Because this is the first time such a laser has been discussed in this journal, I feel it is appropriate to provide a discussion of its function and capabilities. Normal laser safety should be employed, such as not pointing it into eyes or at people, and using eye protection for the young and inexperienced. It is important to note that 589 nm is the same wavelength as the Sodium-D line (doublet). This allows for the laser to serve as a replacement for sodium lamps, and, considering its rather high price, this added value should be balanced against its cost. What follows is a list of activities that showcase the yellow laser's unique promise as an engaging piece of technology that can be used in the teaching of physics.

    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.

    2014-11-01

    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.

  7. Necrotizing Fasciitis in Paroxysmal Nocturnal Hemoglobinuria

    2015-01-01

    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.

    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)

    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.

  8. Unusual tomographic findings of complicated necrotizing pancreatitis

    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.

    Full Text Available Effects of boiling and steaming cooking methods were studied on total polyphenols, antioxidant capacity, and biogenic amines of three green bean varieties, purple, yellow, and green. The vegetables gave good values both for antioxidant capacity and for phenolics content, with the purple variety being the richest in healthful components. Both the heat treatments affected the antioxidant properties of these vegetables, with boiling that reduced the initial antioxidant capacity till 30% in the yellow variety, having the same trend for total polyphenols, with the major decrement of 43% in the green variety. On the contrary, biogenic amines significantly increased only after boiling in green and yellow variety, while purple variety did not show any changes in biogenic amines after cooking. The steaming method showed being better cooking approach in order to preserve the antioxidant properties of green beans varieties and to maintain the biogenic amines content at the lowest level.

    Wheat disease in Egypt is reviewed and results of mutation breeding by γ irradiation for disease resistance in wheat and field beans are described. Wheat mutants of the variety Giza 155 resistant to leaf rust, Giza 156 resistant to both leaf and yellow rusts, and Tosson with a reasonable level of combined resistance to the three rusts in addition to mutants of the tetraploid variety Dakar 52 with a good level of stem and yellow rust resistance are required. Their seeds were subjected to 10, 15 and 20 krad. Of 3000-3700 M 2 plants from each variety and dosage, 22 plants from both Giza 155 and Giza 156, although susceptible, showed a lower level of disease development. In 1975, M 3 families of these selected plants and 6000 plants from bulked material were grown from each variety and dosage at two locations. Simultaneously, an additional population consisting of 3000 mutagen-treated seeds was grown to have a reasonable chance of detecting mutants; 2 heads from each plant were harvested. These will be grown next season (1976) to make a population of 25,000-30,000 M 2 plants and screened to composite cultures of specific rusts. Vicia faba seeds of field bean varieties Giza 1, Giza 2 and Rebaya 40, equally susceptible to rust and chocolate spot, were subjected to 3, 5 and 7 krad of 60 Co gamma radiation and 800 M 1 plants were grown in 1972 per variety and dose. Up to this later growing season (M 3 ) no resistance was detected in M 3 plank

    Seed coat colour of bean seeds is decisive for acceptance of a cultivar. The objectives of this research were to determine whether there is maternal effect for "L", a* and b* colour parameters in Middle American and Andean bean seeds; to obtain estimates of heritability and gain with selection for "L", a* and b* values; and select recombinants with the seed coat colour required by the market demand. Thus, controlled crossings were carried out between the Middle American lines CNFP 10104 and CHC 01-175, and between the Andean lines Cal 96 and Hooter, for obtaining F1, F1 reciprocal, F2 and F2 reciprocal generations for each hybrid combination. Parents and generations were evaluated in two field experiments (2012 normal rainy and 2013 dry seasons) in the state of Rio Grande do Sul, Brazil. Seed coat colour was quantified with a portable colorimeter. Genetic variability for "L" (luminosity), chromaticity a* (green to red shade), and chromaticity b* (blue to yellow shade) values was observed in seeds with F2 seed coat of Middle American and Andean beans. "L", a* and b* values in bean seeds presented maternal effects. High broad-sense heritability are observed for luminosity (h(2)b: 76.66-95.07%), chromaticity a* (h(2)b: 73.08-89.31%), and chromaticity b* (h(2)b: 88.63-92.50%) values in bean seeds. From the crossings, it was possible to select bean seeds in early generation for the black group, and for carioca and cranberry types (dark or clear background) which present the colour required by the market demand.

    Beans are a major source of dietary protein in Brazil. However, high losses due to insect infestation occur after each harvest. To combat these losses, radiation processing of beans offers promise as an alternative to chemical treatment, provided the nutritional quality of beans is not impaired by the radiation treatment. Conflicting results have been published about the effect of radiation on the biological value of legume proteins. Therefore, two varieties of Brazilian beans were studied: 1) Phaseolus vulgaris L., var. carioca and 2) Vigna unguiculata (L.) Walp, var. macaçar. The beans were irradiated with doses of 0, 0.5, 1.0, 2.5, 5.0 and 10 kGy. Since irradiated beans will be consumed after appropriate storage, the beans under study were stored for 6 months at ambient temperature. Protein quality was measured by a biological assay employing the nitrogen balance approach in weanling rats. The animals were fed with optimally cooked beans, which were the only source of protein (˜10%). Nitrogen contents of legumes, diets, animal urine and faeces were determined by Kjeldahl analysis. The indices for apparent protein quality: net protein utilisation, digestibility and biological value were not influenced by irradiation. Thus, radiation treatment of Brazilian beans offers considerable promise as an effective insect disinfection process, without impairing the biological quality of the valuable bean protein.

    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

    ABSTRACT A polymerase chain reaction approach using degenerate primers that targeted the conserved domains of cloned plant disease resistance genes (R genes) was used to isolate a set of 15 resistance gene analogs (RGAs) from common bean (Phaseolus vulgaris). Eight different classes of RGAs were obtained from nucleotide binding site (NBS)-based primers and seven from not previously described Toll/Interleukin-1 receptor-like (TIR)-based primers. Putative amino acid sequences of RGAs were significantly similar to R genes and contained additional conserved motifs. The NBS-type RGAs were classified in two subgroups according to the expected final residue in the kinase-2 motif. Eleven RGAs were mapped at 19 loci on eight linkage groups of the common bean genetic map constructed at Centro Internacional de Agricultura Tropical. Genetic linkage was shown for eight RGAs with partial resistance to anthracnose, angular leaf spot (ALS) and Bean golden yellow mosaic virus (BGYMV). RGA1 and RGA2 were associated with resistance loci to anthracnose and BGYMV and were part of two clusters of R genes previously described. A new major cluster was detected by RGA7 and explained up to 63.9% of resistance to ALS and has a putative contribution to anthracnose resistance. These results show the usefulness of RGAs as candidate genes to detect and eventually isolate numerous R genes in common bean.

    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.

    Necrotizing sialometaplasia (NS) which mimics malignancy both clinically and histopathologically is an uncommon benign, self-limiting inflammatory disease of the mucus-secreting minor salivary glands. The lesion is believed to be the result of vascular ischemia that may be initiated by trauma. Till date, the diagnosis of NS remains a challenge. This report demonstrates a case of NS in a 73-year-old male patient who presented with an ulcerative lesion in his palate. He had a history of local trauma and was long-term user of salbutamol inhaler. An incisional biopsy was carried out and the diagnosis was established through history, clinical examination, histopathology using Hematoxylin and Eosin stain. The patient was given symptomatic treatment and the lesion healed in about 7 weeks.

    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.

    Although Indonesia is one of the biggest cocoa beans producers in the world, Indonesian cocoa beans are oftenly of low quality and thereby frequently priced low in the world market. In order to improve the quality, adequate post-harvest cocoa processing techniques are required. Fermentation is the vital stage in series of cocoa beans post harvest processing which could improve the quality of cocoa beans, in particular taste, aroma, and colours. During the fermentation process, combination of microbes grow producing metabolites that serve as the precursors for cocoa beans flavour. Microbial composition and thereby their activities will affect the fermentation performance and influence the properties of cocoa beans. The correlation could be reviewed using a kinetic model that includes unstructured microbial growth, substrate utilization and metabolic product formation. The developed kinetic model could be further used to design cocoa bean fermentation process to meet the expected quality. Further the development of kinetic model of cocoa bean fermentation also serve as a good case study of mixed culture solid state fermentation, that has rarely been studied. This paper presents the development of a kinetic model for solid-state cocoa beans fermentation using an empirical approach. Series of lab scale cocoa bean fermentations, either natural fermentations without starter addition or fermentations with mixed yeast and lactic acid bacteria starter addition, were used for model parameters estimation. The results showed that cocoa beans fermentation can be modelled mathematically and the best model included substrate utilization, microbial growth, metabolites production and its transport. Although the developed model still can not explain the dynamics in microbial population, this model can sufficiently explained the observed changes in sugar concentration as well as metabolic products in the cocoa bean pulp.

    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.

    Necrotizing colitis associated with carcinoma of the colon, known also as obstructive colitis, is a disorder characterized by anulceration and inflammation of the colon proximal to an obstructive lesion, especially carcinoma of the rectosigmoid colon, and in rare instance, leads to acute gangrene of the colon. The authors analyzed radiologic findings in four cases of necrotizing colitis associated with carcinoma of the colon. Barium enema disclosed mucosal edema, nodular filling defects, irregularity of the colonic contour and typical thumbprinting appearance of involved colon proximal to an obstructing carcinoma of the colon. The mechanism of necrotizing colitis was briefly reviewed

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

    Full Text Available The aim of this study was to determine the lethal salinity (LC50 for the yellow clam Mesodesma mactroides (Bivalvia: Mesodesmatidae and identify histopathological alterations that could be used to diagnose structural changes in clam tissue. Clams in two size classes (adults and juveniles were placed in 10 L chambers and exposed to salinities of 35, 30, 25, 20, 15, 10, and 5 g/L. There were triplicate chambers with seven clams each for each salinity. The LC50 values for a 48 h exposure were 6.5 g/L and 5.7 g/L for adults and juveniles, respectively. For a 96 h exposure, the LC50 values were 10.5 g/L for adults and 8.8 g/L for juveniles. The histological examination of yellow clams exposed to 10 g/L for 96 h showed intercellular oedema and necrotic foci in the epithelium of the digestive gland and occlusion of the lumen of the digestive gland. In conclusion, M. mactroides can be characterised as a moderately euryhaline species, tolerating salinities from 35 to 15 g/L.

    The capacities of the begomoviruses Bean dwarf mosaic virus (BDMV) and Bean golden yellow mosaic virus (BGYMV) to differeBean dwarf mosaic viru certain common bean (Phaseolus vulgaris) cultivars were used to identify viral determinants of the hypersensitive response (HR) and avirulence (avr) in BDMV. A series of hybrid DNA-B components, containing BDMV and BGYMV sequences, was constructed and coinoculated with BDMV DNA-A (BDMV-A) or BDMVA-green florescent protein into seedlings of cv. Topcrop (susceptible to BDMV and BGYMV) and the BDMV-resistant cvs. Othello and Black Turtle Soup T-39 (BTS). The BDMV avr determinant, in bean hypocotyl tissue, was mapped to the BDMV BV1 open reading frame and, most likely, to the BV1 protein. The BV1 also was identified as the determinant of the HR in Othello. However, the HR was not required for resistance in Othello nor was it associated with BDMV resistance in BTS. BDMV BV1, a nuclear shuttle protein that mediates viral DNA export from the nucleus, represents a new class of viral avr determinant. These results are discussed in terms of the relationship between the HR and resistance.

    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. The mean number of days patients were intubated was 5.2 ± 5.1 days and the mean ICU stay was 6.4 ± 5.2 days. Sixty percent of cases had multiorgan dysfunction (MODS and one patient died, resulting in a mortality rate of 20%. Conclusion : According to our study, CNF represents around 5% of NF patients. CNF was higher among male patients and in

    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.

    Dried beans (often referred to as grain legumes) may contribute to some of the health benefits associated with plant-based diets. Beans are rich in a number of important micronutrients, including potassium, magnesium, folate, iron, and zinc, and are important sources of protein in vegetarian diets. In particular, they are among the only plant foods that provide significant amounts of the indispensable amino acid lysine. Commonly consumed dried beans are also rich in total and soluble fiber as well as in resistant starch, all of which contribute to the low glycemic index of these foods. They also provide ample amounts of polyphenols, many of which are potent antioxidants. Intervention and prospective research suggests that diets that include beans reduce low-density lipoprotein cholesterol, favorably affect risk factors for metabolic syndrome, and reduce risk of ischemic heart disease and diabetes. The relatively low bean intakes of North Americans and northern Europeans can be attributed to a negative culinary image as well as to intestinal discomfort attributable to the oligosaccharide content of beans. Cooking practices such as sprouting beans, soaking and discarding soaking water before cooking, and cooking in water with a more alkaline pH can reduce oligosaccharide content. Promotional efforts are needed to increase bean intake. © 2014 American Society for Nutrition.

    2014-04-01

    Full Text Available Castor bean crops are agriculturally relevant due to the quality and versatility of their oil, both for the chemical industry and for biodiesel production. Proper weed management is important for both the cultivation and the yield of castor bean crops; therefore, the intention of the present work is to review pertinent information regarding weed management, including the studies regarding weed interference periods, chemical controls for use in different crop production systems and herbicide selectivity, for castor bean crops. Weed science research for castor bean crops is scarce. One of the main weed management challenges for castor bean crops is the absence of herbicides registered with the Ministry of Agriculture, Livestock and Food Supply (MALFS. Research for viable herbicides for weed control in castor bean crops should be directed by research and/or rural extension institutions, associations and farmers cooperatives, as well as by manufactures, for the registration of these selective herbicides, which would be primarily used to control eudicotyledons in castor bean crops. New studies involving the integration of weed control methods in castor bean also may increase the efficiency of weed management, for both small farmers using traditional crop methods in the Brazilian Northeast region, as well as for areas with the potential for large scale production, using conservation tillage systems, such as the no-tillage crop production system.

    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.

    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.

    Marker-assisted selection (MAS) in common beans (Phaseolus vulgaris L.) and cassava (Manihot esculenta) is reviewed in relation to the breeding system of each crop and the breeding goals of International Agricultural Research Centres (IARCs) and National Agricultural Research Systems (NARS). The importance of each crop is highlighted and examples of successful use of molecular markers within selection cycles and breeding programmes are given for each. For common beans, examples are given of gene tagging for several traits that are important for bean breeding for tropical environments and aspects considered that contribute to successful application of MAS. Simple traits that are tagged with easy-to-use markers are discussed first as they were the first traits prioritized for breeding at the International Center for Tropical Agriculture (CIAT) and with NARS partners in Central America, Colombia and eastern Africa. The specific genes for MAS selection were the bgm-1 gene for bean golden yellow mosaic virus (BGYMV) resistance and the bc-3 gene for bean common mosaic virus (BCMV) resistance. MAS was efficient for reducing breeding costs under both circumstances as land and labour savings resulted from eliminating susceptible individuals. The use of markers for other simply inherited traits in marker-assisted backcrossing and introgression across Andean and Mesoamerican gene pools is suggested. The possibility of using MAS for quantitative traits such as low soil phosphorus adaptation is also discussed as are the advantages and disadvantages of MAS in a breeding programme. For cassava, the use of multiple flanking markers for selection of a dominant gene, CMD2 for cassava mosaic virus (CMV) resistance at CIAT and the International Institute of Tropical Agriculture (IITA) as well as with NARS partners in the United Republic of Tanzania using a participatory plant breeding scheme are reviewed. MAS for the same gene is important during introgression of cassava green mite

    Barley yellow dwarf virus (BYDV) is a phloem limited virus that is persistently transmitted by aphids. Due to huge yield losses in agriculture, the virus is of high economic relevance. Since the control of the virus itself is not possible, tolerant barley genotypes are considered as the most effective approach to avoid yield losses. Although several genes and quantitative trait loci are known and used in barley breeding for virus tolerance, little is known about molecular and physiological backgrounds of this trait. Therefore, we compared the anatomy and early defense responses of a virus susceptible to those of a virus-tolerant cultivar. One of the very early defense responses is the transmission of electrophysiological reactions. Electrophysiological reactions to BYDV infection might differ between susceptible and tolerant cultivars, since BYDV causes disintegration of sieve elements in susceptible cultivars. The structure of vascular bundles, xylem vessels and sieve elements was examined using microscopy. All three were significantly decreased in size in infected susceptible plants where the virus causes disintegration of sieve elements. This could be associated with an uncontrolled ion exchange between the sieve-element lumen and apoplast. Further, a reduced electrophysiological isolation would negatively affect the propagation of electrophysiological reactions. To test the influence of BYDV infection on electrophysiological reactions, electropotential waves (EPWs) induced by leaf-tip burning were recorded using aphids as bioelectrodes. EPWs in infected susceptible plants disappeared already after 10 cm in contrast to those in healthy susceptible or infected tolerant or healthy tolerant plants. Another early plant defense reaction is an increase in reactive oxygen species (ROS). Using a fluorescent dye, we found a significant increase in ROS content in infected susceptible plants but not in infected tolerant plants. Similar results were found for the

  19. Smog Yellows Taj Mahal

    Science.gov (United States)

    2007-01-01

    Built as a monument to the favorite wife of the Mughal Emperor Shah Jahan, the Taj Mahal has watched over the city of Agra, India, since the mid-seventeenth century with its pillars of gleaming white marble. By the spring of 2007, however, one of the world's most visited landmarks was turning yellow, and a panel of India's parliament had little trouble identifying the culprit: pollution. The panel blamed particles of soot and dirt suspended high in the atmosphere for the Taj Mahal's dinginess. The Taj Mahal's home, Agra, sits not far from the base of the Himalaya, and smog regularly collects along the southern side of the mountain range. On May 16, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image of the area around Agra, India. The closeup image shows the immediate vicinity of the Taj Majal. The larger image shows the surrounding area. In both pictures, dingy, gray-beige haze obscures the satellite's view of the land surface. India had tried to minimize the adverse impact of air pollution on the famous landmark. According to the BBC, in the late 1990s, India's Supreme Court ordered the closure of thousands of iron foundries and kilns that had belched smoke near the monument. Many of the 3 million tourists who visited the Taj Majal each year approached the monument on horse-drawn carriages or battery-operated buses as fossil-fuel-powered vehicles could not drive within 2 kilometers (1.5 miles). Since those efforts have failed to save the Taj Majal's complexion, Indian officials have considered applying a cleansing mud pack to the monument's surface to draw out the dirt. As India industrializes, smog results, and the Taj Mahal's gleaming whiteness is only one casualty. Pollution has been blamed for a decrease in Indian rice harvests, which had soared during the 'Green Revolution' of the 1960s and 1970s. Haze and dust also appear to bring on the region's monsoon rains earlier than normal.

    Objective: To verify if the Bio-Manguinhos 17DD yellow fever vaccine (17DD-YFV) used in lower doses is as immunogenic and safe as the current formulation. Results: Doses from 27,476 IU to 587 IU induced similar seroconversion rates and neutralizing antibodies geometric mean titers (GMTs). Immunity of those who seroconverted to YF was maintained for 10 mo. Reactogenicity was low for all groups. Methods: Young and healthy adult males (n = 900) were recruited and randomized into 6 groups, to receive de-escalating doses of 17DD-YFV, from 27,476 IU to 31 IU. Blood samples were collected before vaccination (for neutralization tests to yellow fever, serology for dengue and clinical chemistry), 3 to 7 d after vaccination (for viremia and clinical chemistry) and 30 d after vaccination (for new yellow fever serology and clinical chemistry). Adverse events diaries were filled out by volunteers during 10 d after vaccination. Volunteers were retested for yellow fever and dengue antibodies 10 mo later. Seropositivity for dengue was found in 87.6% of volunteers before vaccination, but this had no significant influence on conclusions. Conclusion: In young healthy adults Bio-Manguinhos/Fiocruz yellow fever vaccine can be used in much lower doses than usual. International Register ISRCTN 38082350. PMID:23364472

    Takahashi, Makoto; Inai, Yoko; Miyazawa, Norio; Kurobayashi, Yoshiko; Fujita, Akira

    2013-01-01

    The odor-active volatiles in Madagascar vanilla beans (Vanilla planiforia) of two grades, red whole beans as standard quality and cuts beans as substandard quality, were characterized by instrumental and sensory analyses. The higher contents of vanillin and β-damascenone in red whole beans than in cuts beans respectively contributed to significant differences in the sweet and dried fruit-like notes, while the higher contents of guaiacol and 3-phenylpropanoic acid in cuts beans than in red whole beans respectively contributed to significant differences in the phenolic and metallic notes. A sensory evaluation to compare red whole beans and their reconstituted aroma characterized both samples as being similar, while in respect of the phenolic note, the reconstituted aroma significantly differed from the reconstituted aroma with guaiacol added at the concentration ratio of vanillin and guaiacol in cuts beans. It is suggested from these results that the concentration ratio of vanillin and guaiacol could be used as an index for the quality of Madagascar vanilla beans.

    2007-05-15

    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.

  7. [Etiopathogenesis of necrotizing arteritis (leukocytoclastic vasculitis)].

    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

    Yellow or white mustard (Sinapis alba L.) is unique in the mustard family by containing large amounts of mucilaginous material in the seed coat. This material was shown to exhibit similar rheological properties to xanthan gum such as shear thinning flow behavior and weak gel structure. This review will discuss the synergistic interactions between yellow mustard mucilage (YMM) and galactomannans, particularly locust bean gum (LBG), and its potential food applications. In addition, synergistic interactions between YMM, with or without LBG, on starch paste viscosity and syneresis will also be reviewed. The thickening, texturizing and stabilizing properties of YMM, and its ability to form gels at very low concentration in the presence of LBG, could lead to many food and industrial applications.

    A series of experiments has been performed by Ghanaian scientists from 1977 to 1987 to evaluate the seriousness of infestation and to establish effective doses for radiation disinfestation against insects and fungi which cause deterioration in grains and cocoa beans. Supporting investigations have been done on the effect of radiation disinfestation on some quality parameters and wholesomeness of grains (with maize as the test grain) and cocoa beans. A minimum dose of 0.8 kGy was established for effective control of insects present in stored grains and cocoa beans. For the decontamination against fungi and yeasts, a combination of moist heat (85% RH) applied to 60 deg. C for 30 min followed by a dose of 4 kGy was effective for maize and moist heat (85% RH) applied 80 deg. C and a dose of 4 kGy was recommended for cocoa beans. No significant difference was found between the organoleptic qualities of the products from maize and cocoa that had been treated with moist heat and radiation and the untreated samples. The cooling (solidifying) curves of cocoa butter prepared from untreated and treated cocoa beans were very similar. Irradiated cocoa beans were found to be wholesome. The prospects of radiation disinfestation of grains and cocoa beans have also been discussed. (author). 27 refs, 4 tabs

    The objective of this study was to compare the emission rate and expansion of the leaves, duration of the leaf area (DLA) and the extinction coefficient (k) for the crops soybean and of the bean, and for the weeds Euphorbia heterophylla sensitive and Euphorbia heterophylla resistant to the herbicides inhibiting of the ALS enzyme, Bidens pilosa and Desmodium tortuosum. The experiment was developed in the field, in soil classified as Red-Yellow Claysoil, in the period of october of 2000 to march of 2001. Each plant species consisted of a treatment. The treatments were arranged in a randomized complete block design with four replications. The mensurations of the photosynthetically active radiation (PAR) were accomplished in two points of the plants: above and bellow the canopy, by means of a light ceptometer. The emission rate and the expansion of leaves was calculated at the end of the cycle of the crops. The DLA and k were calculated before and after the plant flowering. It was not observed differences in the development of the biotypes of E. heterophylla with relation to the rate of appearance of leaves, expansion rate, DLA or k. Among the cultures, the bean presented smaller leaf emission rate (0.591 / day) compared to the soybean (0.933 / day). Among the weeds, the largest leaf emission rate was with D. tortuosum (0.699 / day). The leaf expansion rate observed by the soybean was superior to all the other species (6.77 cm 2 .day-1). All plant species presented larger value for DLA after the flowering compared before flowering. The soybean presented larger value of k (before and after the flowering 0.52 and 0.93, respectively) compared to the other species, demonstrating high potential of interception of solar radiation.

    Cocoa beans (Theobroma cacao) are the major raw material for chocolate production and fermentation of the beans is essential for the development of chocolate flavor precursors. In this study, a novel approach was used to determine the role of yeasts in cocoa fermentation and their contribution to chocolate quality. Cocoa bean fermentations were conducted with the addition of 200ppm Natamycin to inhibit the growth of yeasts, and the resultant microbial ecology and metabolism, bean chemistry and chocolate quality were compared with those of normal (control) fermentations. The yeasts Hanseniaspora guilliermondii, Pichia kudriavzevii and Kluyveromyces marxianus, the lactic acid bacteria Lactobacillus plantarum and Lactobacillus fermentum and the acetic acid bacteria Acetobacter pasteurianus and Gluconobacter frateurii were the major species found in the control fermentation. In fermentations with the presence of Natamycin, the same bacterial species grew but yeast growth was inhibited. Physical and chemical analyses showed that beans fermented without yeasts had increased shell content, lower production of ethanol, higher alcohols and esters throughout fermentation and lesser presence of pyrazines in the roasted product. Quality tests revealed that beans fermented without yeasts were purplish-violet in color and not fully brown, and chocolate prepared from these beans tasted more acid and lacked characteristic chocolate flavor. Beans fermented with yeast growth were fully brown in color and gave chocolate with typical characters which were clearly preferred by sensory panels. Our findings demonstrate that yeast growth and activity were essential for cocoa bean fermentation and the development of chocolate characteristics. Crown Copyright © 2014. Published by Elsevier B.V.

    Mexican bean beetle, Epilachna varivestis Mulsant, is a serious pest of snap beans, Phaseolus vulgaris L., in the eastern United States. These beetles are intolerant to direct sunlight, explaining why individuals are typically found on the undersides of leaves and in the lower portion of the plant canopy. We hypothesized that snap beans grown on reflective, agricultural polyethylene (plastic mulch) would have fewer Mexican bean beetles and less injury than those grown on black plastic or bare soil. In 2014 and 2015, beans were seeded into beds of metallized, white, and black plastic, and bare soil, in field plots near Blacksburg, VA. Mexican bean beetle density, feeding injury, predatory arthropods, and snap bean yield were sampled. Reflected light intensity, temperature, and humidity were monitored using data loggers. Pyranometer readings showed that reflected light intensity was highest over metallized plastic and second highest over white plastic; black plastic and bare soil were similarly low. Temperature and humidity were unaffected by treatments. Significant reductions in Mexican bean beetle densities and feeding injury were observed in both metallized and white plastic plots compared to black plastic and bare soil, with metallized plastic having the fewest Mexican bean beetle life stages and injury. Predatory arthropod densities were not reduced by reflective plastic. Metallized plots produced the highest yields, followed by white. The results of this study suggest that growing snap beans on reflective plastic mulch can suppress the incidence and damage of Mexican bean beetle, and increase yield in snap beans. © The Authors 2016.

    1. Saimiri sciureus has been infected with yellow fever virus, both by the inoculation of infectious blood and by the bites of infective mosquitoes. Some of the monkeys have died, showing lesions, including hepatic necrosis, suggesting yellow fever as seen in human beings and in rhesus monkeys. Virus has been transferred back to M. rhesus from infected Saimiri both by blood inoculation and by mosquito bites. The virus undoubtedly has been maintained through four direct passages in Saimiri. Reinoculations of infectious material into recovered monkeys have not given rise to invasion of the blood stream by virus. Sera from recovered animals have protected M. rhesus against the inoculation of virus. 2. It has been possible to pass the virus to and from Ateleus ater by the injection of blood or liver and by the bites of mosquitoes. The livers from two infected animals have shown no necrosis. The serum from one recovered monkey proved to be protective for M. rhesus. 3. Only three out of twelve Lagothrix lagotricha have reacted to yellow fever virus by a rise in temperature. Probably none have died as a result of the infection. In only one instance has the virus been transferred back to M. rhesus. The sera of recovered animals have had a protective action against yellow fever virus. PMID:19869721

    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).

    Patients may use Internet Yellow Pages to help select a physician. We sought to describe dermatology Internet Yellow Page advertising. Dermatology advertisements in Colorado, California, New York, and Texas at 3 Yellow Page World Wide Web sites were systematically examined. Most advertisements (76%; 223/292) listed only one provider, 56 listed more than one provider, and 13 listed no practitioner names. Five advertisements listed provider names without any credentialing letters, 265 listed at least one doctor of medicine or osteopathy, and 9 listed only providers with other credentials (6 doctors of podiatric medicine and 3 registered nurses). Most advertisements (61%; 179/292) listed a doctor of medicine or osteopathy claiming board certification, 78% (139/179) in dermatology and 22% (40/179) in other medical specialties. Four (1%; 4/292) claims of board certification could not be verified (one each in dermatology, family practice, dermatologic/cosmetologic surgery, and laser surgery). Board certification could be verified for most doctors of medicine and osteopathy not advertising claims of board certification (68%; 41/60; 32 dermatology, 9 other specialties). A total of 50 advertisements (17%) contained unverifiable or no board certification information, and 47 (16%) listed a physician with verifiable board certification in a field other than dermatology. All Internet Yellow Page World Wide Web sites and all US states were not examined. Nonphysicians, physicians board certified in medical specialties other than dermatology, and individuals without verifiable board certification in any medical specialty are advertising in dermatology Internet Yellow Pages. Many board-certified dermatologists are not advertising this certification.

    Vegetables are important sources of dietary fiber, vitamins and minerals in the diets of children. The United States Department of Agriculture (USDA) National School Lunch Program has new requirements for weekly servings of vegetable subgroups as well as beans and peas. This study estimated the cost impact of meeting the USDA requirements using 2008 national prices for 98 vegetables, fresh, frozen, and canned. Food costs were calculated per 100 grams, per 100 calories, and per edible cup. Rank 6 score, a nutrient density measure was based on six nutrients: dietary fiber; potassium; magnesium; and vitamins A, C, and K. Individual nutrient costs were measured as the monetary cost of 10% daily value of each nutrient per cup equivalent. ANOVAs with post hoc tests showed that beans and starchy vegetables, including white potatoes, were cheaper per 100 calories than were dark-green and deep-yellow vegetables. Fresh, frozen, and canned vegetables had similar nutrient profiles and provided comparable nutritional value. However, less than half (n = 46) of the 98 vegetables listed by the USDA were were consumed >5 times by children and adolescents in the 2003-4 National Health and Nutrition Examination Survey database. For the more frequently consumed vegetables, potatoes and beans were the lowest-cost sources of potassium and fiber. These new metrics of affordable nutrition can help food service and health professionals identify those vegetable subgroups in the school lunch that provide the best nutritional value per penny.

    2013-01-01

    Common beans (Phaseolus vulgaris L.) originated in the New World and are the grain legume of greatest production for direct human consumption. Common bean production is subject to frequent droughts in highland Mexico, in the Pacific coast of Central America, in northeast Brazil, and in eastern and southern Africa from Ethiopia to South Africa. This article reviews efforts to improve common bean for drought tolerance, referring to genetic diversity for drought response, the physiology of drought tolerance mechanisms, and breeding strategies. Different races of common bean respond differently to drought, with race Durango of highland Mexico being a major source of genes. Sister species of P. vulgaris likewise have unique traits, especially P. acutifolius which is well adapted to dryland conditions. Diverse sources of tolerance may have different mechanisms of plant response, implying the need for different methods of phenotyping to recognize the relevant traits. Practical considerations of field management are discussed including: trial planning; water management; and field preparation. PMID:23507928

  8. Antibiotics in acute necrotizing pancreatitis --- perspective of a developing country

    International Nuclear Information System (INIS)

    Khan, A.; Khan, S.

    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.

    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.

    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.

    The aim of the present study was to evaluate the effect of canning on color, protein and phenolic profile of grains of kidney bean, field pea and chickpea varieties/accession. Color of grains of different pulses was enhanced after canning. Grains L* (lightness) decreased while a* (redness to yellowness) and b* (greenness to blueness) increased after canning in all the pulses. Protein profiling of grains of different pulses after canning revealed that kidney bean and chickpea, respectively, had the least and the most thermally susceptible polypeptides. Kidney bean and chickpea showed higher Percentage washed drained weight (PWDW) than field pea. Pulse with more grain hardness and PWDW showed higher degree of grain splitting during canning. Grain splitting was also higher in dark colored accessions/varieties as compared to the light colored. Ferulic acid was the most predominant compound present in raw grains of different pulses. Raw kidney bean grains showed higher accumulation of catechin, chlorogenic, protocatechuic acid, p-coumaric acid and ferulic acid than those of chickpea and field pea. Canning caused reduction in all the phenolic compounds except gallic acid and most prominent effect of canning on protocatechuic acid, chlorogenic and ferulic acid was observed. Copyright © 2016.

    1999-01-01

    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.

  15. Necrotizing Soft Tissue Infection Occurring after Exposure to Mycobacterium marinum

    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.

    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.

    2011-12-01

    Full Text Available Four 3-4 month-old chinchillas (Chinchilla lanigera from a commercial flock of 395 chinchillas, were found dead with evidence of previous diarrhea and prolapsed rectum. A fifth 8 month-old chinchilla died 8 hours after being found recumbent, apathetic, diarrheic and with a prolapsed rectum. Two chinchillas were necropsied and observed gross lesions consisted of extensive hemorrhagic enteritis, mild pulmonary edema and enlarged and yellow liver; this latter finding was particularly prominent in the chinchilla presenting longer clinical course. Histologically there was necrotizing enteritis associated with abundant bacterial rods aggregates in the intestinal surface epithelium and within the lamina propria. In the lungs there were small amounts of pink proteinaceous material (edema in the interstitium and marked vacuolar hepatocellullar degeneration (lipidosis in the liver. Anaerobic cultures from the intestinal contents of one of the affected chinchillas yielded Clostridium perfringens. Genotyping of this C. perfringens isolate was achieved by multiplex polymerase chain reaction (mPCR as C. perfringenstype B due to detection of alpha, beta and epsilon-toxin genes. These findings suggest C. perfringens type B as an important cause of sudden or acute death in chinchillas.

    2012-01-16

    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.

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

    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.

    An Embellisia sp. has been established as the cause of a new disease of the herbaceous perennial forage legume, 'standing milkvetch' (Astragalus adsurgens Pall.) in Northern China, which severely reduces plant density and degrades A. adsurgens stands. The disease was common at an experimental location in Gansu Province where it was recognized by the occurrence of stunted plants with reddish-brown stems and yellow and necrotic leaf blades. An Embellisia sp. was isolated from symptomatic stem, leaf blade, petiole, and root tissues at varying frequencies of up to 90%. Single-spore isolates grew very slowly on PCA, PDA, V-8 and, wheat hay decoction agar. Pathogenicity was confirmed by inoculation of seeds, dipping 2-day-old pre-germinated seedlings in inoculum and spraying inoculum on 6-month-old plants. Symptoms on test plants included yellow leaf lesions, brown lesions on stems and petioles, stunted side-shoots with yellow, small, distorted and necrotic leaves, shoot blight, bud death, crown rot, root rot, and plant death. The disease is named as 'yellow stunt and root rot' of A. adsurgens to distinguish it from diseases caused by other known pathogens. Embellisia sp. is also pathogenic to A. sinicus but not to 11 other tested plant species.

    Yam bean is a common food in southern Taiwan. However, its seeds are rarely consumed. We describe five patients of yam bean seed poisoning in Taiwan, one of them life-threatening. The five patients presented with perioral numbness, nausea and vomiting after eating a same soup made from yam bean seeds. One of them, a 54-year-old woman, had difficulty breathing and lost consciousness. Physical examination showed dilated pupils and coma with no focal neurological signs. The initial blood pressure was normal. Laboratory data showed a severe anion gap metabolic acidosis, with a serum lactate level of 185 mg/dL. An initial diagnosis of cyanide intoxication was considered and she was given sodium nitrite and sodium thiosulfate i.v. Hypotension ensued shortly afterwards and pulmonary artery catheterization showed a decreased cardiac index. Aggressive fluid and inotropic therapy were given and the patient eventually recovered. The other four patients suffered only minor gastrointestinal and neurological symptoms and received supportive treatment. Cyanide levels were negative in all five patients. Yam bean seed poisoning can cause acute metabolic acidosis and altered mental status, which could be confused with acute cyanide intoxication from a cyanogenic glycoside-containing plant. To our knowledge, this is the first outbreak of yam bean seed poisoning reported in the English published work.

    Full Text Available A study of water use by bean winter crop (Phaseolus vulgaris, L., cv. Carioca was carried out in a Red Yellow Latosol, clay texture. A furrow irrigation system maintained soil water potentials higher than -40 KPa. Two broadcast nitrogen treatments (0 and 30 kg N/ha were applied 25 days after planting. The major objectives were to study the nitrogen and evapotranspiration interaction and measure the crop coefficients (Kc. The maximum average evapotranspiration (ETm was 1.71 mm/day, or 157.16 mm over 92 days of observations; the ETm values for the vegetative (1, flowering (2 and pod formation (3 phases were 1.48, 2.35, and 1.50 mm/day, respectively, for the 30 kg/ha nitrogen treatment, and 1.48, 1.88 and 1.45 mm/day for the no nitrogen treatment. The crop coefficients (Kc = ETm / ETo were 0.62 and 0.78 for the phase 1, 0.80 and 1.10 for the phase 2, 0.45 and 0.55 for the phase 3 and 0.61 and 0.80 for the entire cycle, based on the FAO-Penman and Class A Pan reference methods (ETo, respectively. The latter one was the best approach to estimate maximum water use by winter bean crop. Nitrogen treatments did not affect evapotranspiration significantly. However, the measured evapotranspiration obtained from the water balance method was 59.78 and 27.12% higher in the flowering than in the vegetative phase, respectively, under 30 and 0 kg N/ha.Um estudo sobre o uso de água do feijoeiro de inverno (Phaseolus vulgaris L. cv.

    Full Text Available Yellow nail syndrome is a rare disease of unclear etiology. We describe a patient who develops yellow nail syndrome, with primary nail and sinus manifestations, shortly after amalgam dental implants. A study of the patient's nail shedding showed elevated nail titanium levels. The patient had her dental implants removed and had complete resolution of her sinus symptoms with no change in her nail findings. Since the patient's nail findings did not resolve we do not believe titanium exposure is a cause of her yellow nail syndrome but perhaps a possible relationship exists between titanium exposure and yellow nail syndrome that requires further studies.

  7. Methyl bromide residues in fumigated cocoa beans

    International Nuclear Information System (INIS)

    Adomako, D.

    1975-01-01

    The 14 C activity in unroasted [ 14 C]-methyl bromide fumigated cocoa beans was used to study the fate and persistence of CH 3 Br in the stored beans. About 70% of the residues occurred in the shells. Unchanged CH 3 Br could not be detected, all the sorbed CH 3 Br having reacted with bean constituents apparently to form 14 C-methylated derivatives and inorganic bromide. No 14 C activity was found in the lipid fraction. Roasting decreased the bound (non-volatile) residues, with corresponding changes in the activities and amounts of free sugars, free and protein amino acids. Roasted nibs and shells showed a two-fold increase in the volatile fraction of the 14 C residue. This fraction may be related to the volatile aroma compounds formed by Maillard-type reactions.

    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

    2009-04-01

    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 Nitrogen (15N released from sunnhemp (Crotalaria juncea, velvet bean (Mucuna aterrima and from Phaseolus bean residues was evaluated after incubation of the plant material in an Eutrudox and a Paleudalf, in a greenhouse experiment with pots containing 6 kg of air dried soil. Dry matter equivalent to 13 Mg ha-1 of Phaseolus bean residues and the same amount of above ground parts of the leguminous species, associated to 2.7 and 2.2 Mg ha-1 of roots of sunnhemp and velvet bean respectively, were incorporated into the soil. A completely randomized experimental design was adopted, with treatments arranged in a 2 3 + 1 factorial, replicated three times. The treatments were the following: two soils (Eutrudox and Paleudalf and three plant materials: two green-manures (sunnhemp or velvet bean, and Phaseolus bean residues, besides one control without plant incorporation into the soil. For the green-manure treatments there were two sub-treatments for each legume species, with 15N labeling of either shoots or roots. Soil moisture was maintained relatively constant during the experiment al period and the treatments were sampled weekly during 49 days. Total mineral nitrogen in the soil, as well as that derived from the legume plants were determined by isotope dilution. Nitrogen from the velvet bean accounted for a greater proportion of the soil inorganic N; shoots were responsible for most of N accumulated. Dry bean residues caused immobilization of inorganic N. The leguminous species added were intensively and promptly mineralized preserving the soil native nitrogen. Mineralization of the legume plant N was greater in the Paleudalf soil than in the Eutrudox.

For the green-manure treatments there were two sub-treatments for each legume species, with {sup 15}N labeling of either shoots or roots. Soil moisture was maintained relatively constant during the experimental period and the treatments were sampled weekly during 49 days. Total mineral nitrogen in the soil, as well as that derived from the legume plants were determined by isotope dilution. Nitrogen from the velvet bean accounted for a greater proportion of the soil inorganic N; shoots were responsible for most of N accumulated. Dry bean residues caused immobilization of inorganic N. The leguminous species added were intensively and promptly mineralized preserving the soil native nitrogen. Mineralization of the legume plant N was greater in the Paleudalf soil than in the Eutrudox. (author)

    Fermentation is a crucial step in the post-harvest processing of cocoa beans. This process comprises mixed culture microbial activities on the cocoa bean pulp, producing metabolites that act as important precursors for cocoa flavour development. Variations in the microbial population dynamics during the fermentation process may induce changes in the overall process. Thus, the introduction of a specific microbial starter culture may improve the quality of the fer...

    Seeds of bean, peas and broad bean, purchased from local seed production plants in the provinces of Mazowieckie and Kujawsko-Pomorskie in the years 1999-2002, were determined for the contents of fifteen polycyclic aromatic hydrocarbons. The hydrocarbons were extracted from the seeds with a hexane-acetone mixture by means of sonification. The obtained extracts were then purified in a silica gel column. Polycyclic aromatic hydrocarbons (PAH) were identified and determined quantitatively with liquid chromatography using a fluorescent detector. The presence (in different concentrations) of PAH was reported in the majority of seeds of the bean, peas and broad bean varieties examined, which indicates that they may be ingested with food and bioaccumulated in the human organism. A considerably higher content of SPAH was observed in the seeds of broad bean, compared to those of bean and peas. The highest SPAH determined reached 2 x 10(2) microg/kg of product. The obtained results were comparable with those reported by other authors for vegetables originating from non-industrial areas. It is worth emphasising that all the seeds examined revealed the presence of PAH with carcinogenic properties.

    Globally, 800 million people are malnourished. Heavily subsidised farmers in rich countries produce sufficient surplus food to feed the hungry, but not at a price the poor can afford. Even donating the rich world's surplus to the poor would not solve the problem. Most poor people earn their living from agriculture, so a deluge of free food would destroy their livelihoods. Thus, the only answer to world hunger is to safeguard and improve the productivity of farmers in poor countries. Diets of subsistence level farmers in Africa and Latin America often contain sufficient carbohydrates (through cassava, corn/maize, rice, wheat, etc.), but are poor in proteins. Dietary proteins can take the form of scarce animal products (eggs, milk, meat, etc.), but are usually derived from legumes (plants of the bean and pea family). Legumes are vital in agriculture as they form associations with bacteria that 'fix-nitrogen' from the air. Effectively this amounts to internal fertilisation and is the main reason that legumes are richer in proteins than all other plants. Thousands of legume species exist but more common beans (Phaseolus vulgaris L.) are eaten than any other. In some countries such as Mexico and Brazil, beans are the primary source of protein in human diets. As half the grain legumes consumed worldwide are common beans, they represent the species of choice for the study of grain legume nutrition. Unfortunately, the yields of common beans are low even by the standards of legumes, and the quality of their seed proteins is sub-optimal. Most probably this results from millennia of selection for stable rather than high yield, and as such, is a problem that can be redressed by modem genetic techniques. We have formed an international consortium called 'Phaseomics' to establish the necessary framework of knowledge and materials that will result in disease-resistant, stress-tolerant, high-quality protein and high-yielding beans. Phaseomics will be instrumental in improving

    Zinc is a trace element and it is absolutely essential for the normal healthy growth of plants. This element plays a part of several enzyme systems and other metabolic functions in the plants. Castor beans (Ricinus communis L.) crop is raising attention as an alternative crop for oil and biodiesel production. Despite the mineral fertilization is an important factor for increasing castor beans yield, few researches has been made on this issue, mainly on the use of zinc. In order to evaluate the effects of zinc on growth of this plant an experiment was carried out in a greenhouse, in Campina Grande, Paraiba State, Brazil, from July to December 2007. The substrate for the pot plants was a 6 mm-sieved surface soil (Neossolo Quartzarenico). The experimental design was a completely randomized with three replications. The treatments were composed of five levels of Zn (0; 2; 4; 6 and 8 mg dm{sup -3}), which were applied at the time of planting. One plant of castor bean, cultivar BRS 188 - Paraguacu, was grown per pot after thinning and was irrigated whenever necessary. Data on plant height, number and length of leaves and stem diameter were measured at 21, 34, 77 and 103 days after planting. Under conditions that the experiment was carried out the results showed that the Zn levels used, did not affect the castor bean plants growth. (author)

    The western bean cutworm, Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), is a recent pest of corn, dry,and snap beans, in the Great Lakes region, and best practices for its management in beans need to be established.Insecticide efficacy and application timing field studies, conducted in 2011–2013, determined that lambda-cyhalothrin and chlorantraniliprole were capable of reducing western bean cutworm feeding damage in dry beans from 2.3 to 0.4% in preharvest samples, and in snap beans from 4.8 to 0.1% of marketable pods, respectively. The best application timing in dry beans was determined to be 4–18 d after 50% egg hatch. No economic benefit was found when products were applied to dry beans, and despite high artificial inoculation rates, damage to marketable yield was relatively low. Thiamethoxam, methoxyfenozide, and spinetoram were also found to be effective at reducing western bean cutworm damage in dry bean to as low as 0.3% compared to an untreated control with 2.5% damaged pods. In snap beans, increased return on investment between CAD$400 and CAD$600 was seen with multiple applications of lambda-cyhalothrin, and with chlorantraniliprole applied 4 d after egg mass infestation.

    A number of viruses in the family Flaviviridae are the focus of efforts to develop effective antiviral therapies. Success has been achieved with inhibitors for the treatment of hepatitis C, and there is interest in clinical trials of drugs against dengue fever. Antiviral therapies have also been evaluated in patients with Japanese encephalitis and West Nile encephalitis. However, no treatment has been developed against the prototype flavivirus, yellow fever virus (YFV). Despite the availability of the live, attenuated 17D vaccine, thousands of cases of YF continue to occur each year in Africa and South America, with a significant mortality rate. In addition, a small number of vaccinees develop severe systemic infections with the 17D virus. This paper reviews current efforts to develop antiviral therapies, either directly targeting the virus or blocking detrimental host responses to infection. PMID:23237991

    Full Text Available A diagnostic method based on nested-PCR, followed by ELISA and conventional bacteriology tests, for the rapid and reliable detection of halo blight pathogen Pseudomonas savastanoi pv. phaseolicola (Psp collected from infected bean leaves and seeds is described. Psp formed white, small and flat colonies on nutrient agar medium, creamy white, flat and circular on Milk-Tween agar medium and light yellow, convex and shiny on modified sucrose peptone agar medium. Eighteen Gram-negative, catalase-positive and oxidase-negative strains were subjected to nested PCR with primers P 5.1/P 3.1 and P 5.2/P 3.2, which directed the amplification of the 450 bp target DNA fragment in all tested strains. According to the results of DAS- and PTA-ELISA with respect to reactivity to specific antibodies, all analyzed strains belonged to Psp bacterium. Pathogenicity was tested on bean pods and cotyledon leaves, on which greasy spots were formed. Psp did not cause hypersensitive reaction on the leaves of tobacco and geranium. Strains produced levan, fluorescent pigment, oxidative metabolism of glucose, did not reduce nitrate, did not produce indole and H2S, did not hydrolyze starch, gelatin and esculin; they produced acid from glucose, mannose, sucrose and glycerol, and did not produce acid from maltose, starch, esculin, dulcite, sorbitol, inositol and erythritol.

    Consumption of dry beans has been relatively flat over the last decade. Creating new bean products may increase the consumption of beans and allow more consumers to obtain the health benefits of beans. In this study, pinto, navy and black beans were milled and the resulting flours extruded into puffs. Unflavored extruded puffs were evaluated by untrained panelists using a hedonic scale for appearance, flavor, texture and overall acceptability. The compositions of raw flours and extrudates were characterized. Sensory results indicated that all beans met or exceeded the minimum requirement for acceptability. Overall acceptability of navy and pinto beans was not significantly different, while acceptability of black bean puffs was significantly lower. Total protein (198-217 g kg(-1)) in extrudates was significantly different among the three beans. Total starch ranged from 398 to 406 g kg(-1) and was not significantly different. Resistant starch, total extractable lipid and raffinose contents were significantly reduced by extrusion. Extrusion did not affect crude fiber and phytic acid contents. The minimal effects on protein and fiber contents, the significant reduction in raffinose content and the acceptability of the unflavored extruded puffs support using various bean flours as ingredients in extruded puffed products. © 2014 Society of Chemical Industry.

    Full Text Available Besides its importance in the coffee tree nutrition, there is almost no information relating zinc nutrition and bean quality. This work evaluated the effect of zinc on the coffee yield and bean quality. The experiment was conducted with Coffea arabica L. in "Zona da Mata" region, Minas Gerais, Brazil. Twelve plots were established at random with 4 competitive plants each. Treatments included plants supplemented with zinc (eight plots and control without zinc supplementation (four plots. Plants were subjected to two treatments: zinc supplementation and control. Yield, number of defective beans, beans attacked by berry borers, bean size, cup quality, beans zinc concentration, potassium leaching, electrical conductivity, color index, total tritable acidity, pH, chlorogenic acids contents and ferric-reducing antioxidant activity of beans were evaluated. Zinc positively affected quality of coffee beans, which presented lower percentage of medium and small beans, lower berry borer incidence, lower potassium leaching and electrical conductivity, higher contents of zinc and chlorogenic acids and higher antioxidant activity in comparison with control beans.

    Full Text Available The theobromine and catechin content can affect the quality of cocoa liquor and is influenced by cacao variety, production area (PA, and fermentation, as well as the method of drying beans (FDB and cocoa liquor production (CLP. This study examined variationsin methylxanthine and catechin levels in fresh and fermented cocoa beans, dried cocoa grains, and in cocoa liquor from Trinitario, Criollo, and Forastero cacao varieties. A total of 123 cocoa bean samples from three Peruvian PAs at different altitudes, Tingo María (TM, San Alejandro (SA, and Curimana (CU, were evaluated. The theobromine (Tb and caffeine (Cf contents in fresh cocoa beans were affected by both cocoa type and PA. The caffeine content was higher in Trinitario cacao than in Criollo and Forastero varieties (p ≤ 0.05. The Tb and CF contents decreased in dry cocoa grain and was affected by FDB (p ≤ 0.05 (1.449 ± 0.004 to 1.140 ± 0.010 and 0.410 ± 0.03 to 0.165 ± 0.02 g Tb and C, respectively, per 100 g dry weight. Cocoa beans from Tingo María, which has thehighest altitude, had higher Tb and CF contents than those from other PAs. The catechin (C and epicatechin (EC contents were affected by the FDB and CLP, and were highestin fresh cocoa beans from the Tingo María area (range: 0.065 ± 0.01 to 0.020 ± 0.00 g C/100 g. The C and EC contents decreased during FDB and CLP (0.001 g C/100 g of cocoa liquor. Taken together, these results show that higher concentrations of Tb, Cf, C,and EC are present in fresh cocoa beans. Moreover, the cocoa variety influenced cocoa liquor quality. Overall, cocoa from the Tingo María PA had the most desirable chemical composition.

    Although Hippocrates (460-c.375 BC) has been traditionally recognized as the Father of Medicine, the fact that he was seminal in the development of cardiology is much less well known. Evidence is presented to support the notion that Hippocrates could also be considered the Father of Cardiology. Hippocrates also had many of the teachings and practices in common with Confucius (c.551-c.479 BC) and the Yellow Emperor of China (2695-2589 BC). Whereas Confucius was not a physician, the Yellow Emperor was an ancient Chinese physician whose Huang Di Neijing, the Yellow Emperor's Canon of Internal Medicine, is the oldest known treatise of medicine in existence.

    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.

    SUMMARY Common bean (Phaseolus vulgaris L.) cultivar (cv.) Othello develops a hypersensitive response-associated vascular resistance to infection by Bean dwarf mosaic virus (BDMV), a single-stranded DNA virus (genus Begomovirus, family Geminiviridae). A PCR-based cDNA subtraction approach was used to identify genes involved in this resistance response. Eighteen clones, potentially involved with BDMV resistance, were identified based upon being up-regulated in BDMV-infected tissues and/or having sequence similarity with known resistance-associated genes. Analysis of these clones revealed potential genes involved in pathogen defence, including pathogenesis-related protein genes and resistance gene analogues (RGAs). Further characterization of one RGA, F1-10, revealed that it encodes a predicted protein with a double Toll/interleukin-1 receptor (TIR) motif. Full-length (F1-10) and spliced (F1-10sp) forms of the RGA were strongly up-regulated in BDMV-infected cv. Othello hypocotyl tissues by 4 days post-inoculation, but not in equivalent mock-inoculated tissues. In agroinfiltration experiments, F1-10, but not F1-10sp, mediated resistance to BDMV in the susceptible common bean cv. Topcrop. By contrast, transgenic Nicotiana benthamiana lines expressing F1-10 or F1-10sp were not resistant to BDMV. Interestingly, when these transgenic lines were inoculated with the potyvirus Bean yellow mosaic virus, some F1-10 lines showed a more severe symptom phenotype compared with non-transgenic control plants. Based on these findings, F1-10 was named: Phaseolus vulgaris VIRUS response TIR-TIR GENE 1 (PvVTT1).

    Bean common mosaic virus (BCMV) is widespread, with Phaseolus species as the primary host plants. Numerous BCMV strains have been identified on the basis of a panel of bean varieties that distinguish the pathogenicity types with respect to the viral strains. The molecular responses in Phaseolus to BCMV infection have not yet been well characterized. We report the transcriptional responses of a widely susceptible variety of common bean (Phaseolus vulgaris L., cultivar 'Stringless green refugee') to two BCMV strains, in a time-course experiment. We also report the genome sequence of a previously unreported BCMV strain. The interaction with the known strain NL1-Iowa causes moderate symptoms and large transcriptional responses, and the newly identified strain (Strain 2 or S2) causes severe symptoms and moderate transcriptional responses. The transcriptional profiles of host plants infected with the two isolates are distinct, and involve numerous differences in splice forms in particular genes, and pathway specific expression patterns. We identified differential host transcriptome response after infection of two different strains of Bean common mosaic virus (BCMV) in common bean (Phaseolus vulgaris L.). Virus infection initiated a suite of changes in gene expression level and patterns in the host plants. Pathways related to defense, gene regulation, metabolic processes, photosynthesis were specifically altered after virus infection. Results presented in this study can increase the understanding of host-pathogen interactions and provide resources for further investigations of the biological mechanisms in BCMV infection and defense.

    To evaluate the safety of biogenic amines, high performance liquid chromatography (HPLC) was used to evaluate the levels of biogenic amines in fermented soya beans and fermented bean curd. In fermented soya beans, the total biogenic amines content was in a relatively safe range in many samples, although the concentration of histamine, tyramine, and β-phenethylamine was high enough in some samples to cause a possible safety threat, and 8 of the 30 samples were deemed unsafe. In fermented bean curd, the total biogenic amines content was more than 900 mg/kg in 19 white sufu amples, a level that has been determined to pose a safety hazard; putrescine was the only one detected in all samples and also had the highest concentration, which made samples a safety hazard; the content of tryptamine, β-phenethylamine, tyramine, and histamine had reached the level of threat to human health in some white and green sufu samples, and that may imply another potential safety risk; and 25 of the 33 samples were unsafe. In conclusion, the content of biogenic amines in all fermented soya bean products should be studied and appropriate limits determined to ensure the safety of eating these foods.

    Full Text Available Fermentation is a crucial step in the post-harvest processing of cocoa beans. This process comprises mixed culture microbial activities on the cocoa bean pulp, producing metabolites that act as important precursors for cocoa flavour development. Variations in the microbial population dynamics during the fermentation process may induce changes in the overall process. Thus, the introduction of a specific microbial starter culture may improve the quality of the fermentation. This article discusses the effects ofthe addition of Saccharomyces cerevisae var. Chevalieri starter culture on cocoa bean fermentation. The dynamics in the yeast concentration, sugary pulp compounds and metabolic products were measured during fermentation. The alterations in the dynamic metabolite profile were significant, although only a slight difference was observed in the yeast population. A higher fermentation index was measured for the cocoa bean fermentation with yeast starter culture, 1.13 compared to 0.84. In conclusion, this method can potentially be applied to shorten the cocoa bean fermentation time.

    Puffing of coffee beans, which induces heat- and pressure-derived physicochemical changes, was applied as an alternative to roasting. Roasted or puffed coffee beans with equivalent lightness values were compared. The moisture content was higher while the crude fat and protein compositions were lower in puffed beans than in roasted beans. The pH was lower and the acid content was higher in puffed beans than in roasted beans. The roasted beans exhibited greater specific volumes, while the puffed beans displayed greater extraction yields. The trigonelline and total phenolic contents were greater in puffed beans than in roasted beans resulting in an enhanced antioxidant capacity. Sensory evaluation of roasted and puffed coffee bean brews revealed that puffing did not affect the flavor or overall acceptance. The current study provides evidence that puffing is an alternative to roasting coffee beans with various benefits. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The way that coffee is prepared (using roasted ground coffee or roasted coffee beans) may influence the quality of beverage. Therefore, the aim of this work is to use ion beam techniques to perform a full elemental analysis of packed roasted ground coffee and packed roasted coffee beans, as well as green coffee beans. The samples were analyzed by PIXE (particle-induced X-ray emission). Light elements were measured through RBS (Rutherford backscattering spectrometry) experiments. Micro-PIXE experiments were carried out in order to check the elemental distribution in the roasted and green coffee beans. In general, the elements found in ground coffee were Mg, P, S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Rb and Sr. A comparison between ground coffee and grinded roasted beans shows significant differences for several elements. Elemental maps reveal that P and K are correlated and practically homogeneously distributed over the beans.

    Full Text Available Abstract The objective of this work was to study the effect of enzymatic hydrolysis of black bean protein concentrate using different enzymes. Bean proteins were extracted and hydrolyzed over a period of 120 min using the enzymes pepsin or alcalase. The protein hydrolysates’ molecular weight was assayed by electrophoresis and the antioxidant activity was evaluated by the capturing methods of free radicals ABTS●+ and DPPH. Electrophoretic results showed that the bands above 50 kDa disappeared, when the beans protein was subjected to hydrolysis with pepsin. The bean protein hydrolysate obtained by hydrolysis with alcalase enzyme, showed higher antioxidant activity for inhibition of the radical ABTS●+. However, the hydrolysates obtained by hydrolysis with pepsin had higher antioxidant activity for inhibition of the radical DPPH. The use of pepsin and alcalase enzymes, under the same reaction time, produced black bean protein hydrolysates with different molecular weight profiles and superior antioxidant activity than the native bean protein.

    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.

    2013-12-13

    In the 19th century, yellow fever thrived in the tropical, urban trade centers along the American Gulf Coast. Industrializing and populated, New Orleans and Memphis made excellent habitats for the yellow fever-carrying Aedes aegypti mosquitoes and the virulence they imparted on their victims. Known for its jaundice and black, blood-filled vomit, the malady terrorized the region for decades, sometimes claiming tens of thousands of lives during the near annual summertime outbreaks. In response to the failing medical community, a small, pronounced population of sick and healthy laypeople openly criticized the efforts to rid the Gulf region of yellow jack. Utilizing newspapers and cartoons to vocalize their opinions, these critics doubted and mocked the medical community, contributing to the regional and seasonal dilemma yellow fever posed for the American South. These sentient expressions prove to be an early example of patient distrust toward caregivers, a current problem in clinical heath care.

    Full Text Available ABSTRACT This study aimed to evaluate the effect of mechanical damage on the hysteresis of beans with induced mechanical damage under different conditions of temperature and relative humidity. Beans (Phaseolus vulgaris L. harvested manually with 35% water content (w.b. were used. Part of this product was subjected to induced mechanical damage by Stein Breakage Tester and controlled drying (damaged and control sample, for sorption processes. The sorption isotherms of water were analyzed for different temperature conditions: 20, 30, 40 and 50 oC; and relative humidity: 0.3; 0.4; 0.5; 0.7 and 0.9 (decimal. Equilibrium moisture content data were correlated with six mathematical models, and the Modified Oswin model was the one that best fitted to the experimental data. According to the above mentioned isotherms, it was possible to observe the phenomenon of hysteresis of damaged and control samples, and this phenomenon was more pronounced in control ones.

    Three forms of lectin (components I, II, and III) from lima beans (Phaseolus lunatus) have been purified on an affinity support containing the synthetic type A blood group trisaccharide alpha-D-GalNAc-(1 leads to 3)-[alpha-L-Fuc-(1 leads to 2)]-beta-D-Gal-(1 leads to). Conversion of components I and II to component III has been achieved by reduction in 10(-2) M dithiothreitol. Isoelectric focusing of lima bean lectin in the presence of 8 M urea and beta-mercaptoethanol revealed charge heterogeneity of the lectin subunits. Three major subunit classes of apparent pI 7.05, 6.65, and 6.45, designated alpha, beta, and alpha', respectively, were identified; they occur in a relative abundance of 2:5:3. Green lima beans harvested before maturity lacked the alpha' subunit (pI 6.45) which appears to accumulate during seed maturation. The three subunits are glycoproteins of identical size and immunochemical reactivity. Identical NH2-terminal sequences were found for the three subunits. Amino acid analysis and tryptic peptide mapping indicated that the observed charge heterogeneity is probably due to differences in the primary structure of the subunits. Studies of subunit composition of charge isolectins provided evidence of nonrandom subunit assembly. A model is proposed involving pairing of a pI 6.65 subunit with either a pI 7.06 or 6.45 subunit to form dimeric units. Possible roles for subunit heterogeneity and ordered subunit assembly in determining the metal and sugar binding properties of lima bean lectin are discussed.

    The complete genome sequence of a bipartite begomovirus (genus Begomovirus, family Geminiviridae) infecting yellow passion fruit (Passiflora edulis) in the state of Valle del Cauca (Colombia) has been determined. The complete DNA-A and DNA-B components were determined to be 2600 and 2572 nt in length, respectively. The DNA-A showed the highest nucleotide sequence identity (87.2 %) to bean dwarf mosaic virus (M88179), a begomovirus found in common bean crops in Colombia, and only 77.4 % identity to passion fruit severe leaf distortion virus (FJ972767), a begomovirus identified infecting passion fruit in Brazil. Based on its sequence identity to all other begomoviruses known to date and in accordance with the ICTV species demarcation criterion for the genus Begomovirus (≥91 % sequence identity for the complete DNA-A), the name passion fruit leaf distortion virus is proposed for this new begomovirus. To our knowledge, this is the first report of a bipartite begomovirus affecting passion fruit in Colombia and the second report of a geminivirus affecting this crop worldwide.

    Beans are important for many developing countries as a source of protein and mineral nutrients. Here, ten commercial types of Brazilian beans, from the species Phaseolus vulgaris (common beans) and Vigna unguiculata (cowpeas), were analyzed by neutron activation analysis for the determination of Br, Ca, Co, Cs, Fe, K, Mo, Na, Rb, Sc and Zn. There were statistical differences (p/0.05) amongst the commercial types, except for Br, Rb and Sc. In general, non-essential elements showed high variability, indicating that the origin of beans had a strong influence on the mass fraction of such elements. (author)

  4. The Effective Design of Bean Bag as a Vibroimpact Damper

    A.Q. Liu

    2000-01-01

    Full Text Available The technique of a bean bag damper has been effectively applied in many engineering fields to control the vibroimpact of a structural system. In this study, the basic parameters responsible for the design of an effective bean bag: the size of beans, the mass ratio of the bean bag to the structure to which it is attached, the clearance distance and the position of the bag, are studied by both theoretical and experimental analyses. These will provide a better understanding of the performance of the bean bag for optimisation of damper design. It was found that reducing the size of beans would increase the exchange of momentum in the system due to the increase in the effective contact areas. Within the range of mass ratios studied, the damping performance of the damper was found to improve with higher mass ratios. There was an optimum clearance for any specific damper whereby the maximum attenuation could be achieved. The position of the bag with respect to nodes and antipodes of the primary structure determined the magnitude of attenuation attainable. Furthermore, the limitations of bean bags have been identified and a general criteria for the design of a bean bag damper has been formulated based on the study undertaken. It was shown that an appropriately configured bean bag damper was capable of reducing the amplitude of vibration by 80% to 90%.

    2018-02-01

    Full Text Available To date, no extensive literature review exists regarding potential uses of mung bean proteins and peptides. As mung bean has long been widely used as a food source, early studies evaluated mung bean nutritional value against the Food and Agriculture Organization of the United Nations (FAO/the World Health Organization (WHO amino acids dietary recommendations. The comparison demonstrated mung bean to be a good protein source, except for deficiencies in sulphur-containing amino acids, methionine and cysteine. Methionine and cysteine residues have been introduced into the 8S globulin through protein engineering technology. Subsequently, purified mung bean proteins and peptides have facilitated the study of their structural and functional properties. Two main types of extraction methods have been reported for isolation of proteins and peptides from mung bean flours, permitting sequencing of major proteins present in mung bean, including albumins and globulins (notably 8S globulin. However, the sequence for albumin deposited in the UniProt database differs from other sequences reported in the literature. Meanwhile, a limited number of reports have revealed other useful bioactivities for proteins and hydrolysed peptides, including angiotensin-converting enzyme inhibitory activity, anti-fungal activity and trypsin inhibitory activity. Consequently, several mung bean hydrolysed peptides have served as effective food additives to prevent proteolysis during storage. Ultimately, further research will reveal other nutritional, functional and bioactive properties of mung bean for uses in diverse applications.

    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.

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.

    Full Text Available Bean characteristics in Robusta coffee (Coffea canephora should be taken into considerations in coffee breeding. Beside genetic factor, environment has been known as an important factor in the formation and change of composition of bean characteristics. This research aimed to find out the effect of long dry season on changes of bean characteristics. The population observed consisted of 277 genotypes originated from reciprocal crossings of three parental namely BP 409, BP 961 and Q 121. Observation was conducted in Kaliwining Experimental Garden of ICCRI in Jember, East Java during two years with different drought intensity i.e. 2005—2006 and 2006—2007 production years. The result showed that long dry season decreased the range value of population of normal beans, pea beans and triage beans, and followed by decreasing in the mean value except for normal beans. Long dry season also influence the change of value range of empty bean to higher proportion, and followed by increasing in the mean value. Distribution pattern of normal beans tend in to remain at high proportion, in contrast to those of pea and triage beans. In other side, long dry season tended to change distribution pattern of empty beans to at high proportion. Correlation analysis among beans characteristics showed that normal beans had negative correlations with pea beans and empty beans. Pea beans had a positive correlation with empty beans. Long dry season decreased proportion of pea bean and triage bean, in contrast to those of empty beans. Increasing proportion of empty bean was caused by failure of growth to normal bean under stress condition. Key words : Coffee canephora, bean characteristics, long dry season, variation, correlation, composition.

    Coffee is a stimulant, psychoactive, popular daily beverage, and its caffeine affects human physiological health and behavior. These important issues prompted us to study caffeine extraction from both the raw and roasted coffee beans of 3 types at different temperatures. A hemispheric model is developed to simulate the extraction process of the caffeine from the coffee beans of hemisphere is proposed. The experimental data are in good agreement with the predicted model. The effective diffusivities of caffeine in both the raw and roasted beans increase with temperature in all 3 types. An incubation period, decreasing with increasing temperature, is observed in all samples studied. Caffeine extraction in roasted beans is more rapid than that for the raw beans and the time difference is significant at low temperatures. In both the raw and roasted samples, caffeine diffusion in the raw beans and the incubation behavior are thermally activated processes. Single activation energies are obtained for diffusion within the extraction temperature range for all beans tested with the exception of one type of the coffee beans, Mandheling, which exhibits 2 activation energies in raw samples. The surface energies of the epidermis of the raw beans and roasted beans obtained from the contact angle measurements are used to interpret the difference of incubation periods. This study has a potential application to the decaffeinated coffee industry.Caffeine affects human physiological health and behavior so that caffeine extraction from coffee beans of different types at different temperatures is important for product refining and customers. © 2018 Institute of Food Technologists®.

  6. The effect of lactic acid bacteria on cocoa bean fermentation.

    Ho, Van Thi Thuy; Zhao, Jian; Fleet, Graham

    2015-07-16

    Cocoa beans (Theobroma cacao L.) are the raw material for chocolate production. Fermentation of cocoa pulp by microorganisms is crucial for developing chocolate flavor precursors. Yeasts conduct an alcoholic fermentation within the bean pulp that is essential for the production of good quality beans, giving typical chocolate characters. However, the roles of bacteria such as lactic acid bacteria and acetic acid bacteria in contributing to the quality of cocoa bean and chocolate are not fully understood. Using controlled laboratory fermentations, this study investigated the contribution of lactic acid bacteria to cocoa bean fermentation. Cocoa beans were fermented under conditions where the growth of lactic acid bacteria was restricted by the use of nisin and lysozyme. The resultant microbial ecology, chemistry and chocolate quality of beans from these fermentations were compared with those of indigenous (control) fermentations. The yeasts Hanseniaspora guilliermondii, Pichia kudriavzevii, Kluyveromyces marxianus and Saccharomyces cerevisiae, the lactic acid bacteria Lactobacillus plantarum, Lactobacillus pentosus and Lactobacillus fermentum and the acetic acid bacteria Acetobacter pasteurianus and Gluconobacter frateurii were the major species found in control fermentations. In fermentations with the presence of nisin and lysozyme, the same species of yeasts and acetic acid bacteria grew but the growth of lactic acid bacteria was prevented or restricted. These beans underwent characteristic alcoholic fermentation where the utilization of sugars and the production of ethanol, organic acids and volatile compounds in the bean pulp and nibs were similar for beans fermented in the presence of lactic acid bacteria. Lactic acid was produced during both fermentations but more so when lactic acid bacteria grew. Beans fermented in the presence or absence of lactic acid bacteria were fully fermented, had similar shell weights and gave acceptable chocolates with no differences

    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.

    2016-04-01

    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.

Results There were more female patients than male patients (male∶female = 1.00∶1.59, with the peak onset age during 40 to 59 years old (43.86% , 25/57 in this study. Clinical types included idiopathic NAM, NAM with connective tissue disease, statin-associated NAM and NAM with cancer. Muscle weakness mainly affected proximal muscle, while it may simultaneously affect distal muscle (28.07% , 16/57. Serum creatine kinase (CK elevated apparently (420-15 320 U/L. Serum anti-signal recognition particle (SRP antibodies were detected in 24 out of 44 patients (54.55%. A total of 41 in 45 patients (91.11% were detected myogenic damage on EMG, and 15 patients (33.33%, 15/45 also had spontaneous potentials. Thigh muscle MRI showed edema in 25 out of 27 patients (92.59% and fatty infiltration in 16 out of 27 patients (59.26% . Other than necrotic fibers, major histocompatibility complex-1 (MHC-1 on sarcolemma were positive in 98.25% (56/57 cases, and membrane attack complex (MAC deposition on capillary walls was detected in 92.98% (53/57 cases. Conclusions NAM can happen in all ages, mainly during 40 to 59 years old. Idiopathic NAM is the main type. Its main manifestation involves weakness of proximal muscle, sometimes with distal muscle. Extra-muscle symptoms are rare. Serum anti-SRP antibodies are common in NAM and edema is prominent change in thigh MRI. DOI: 10.3969/j.issn.1672-6731.2016.10.009

    Full Text Available Quality standard for coffee as an agriculture commodity in Indonesia uses defect system which is regulated in Standar Nasional Indonesia (SNI for coffee bean, No: 01-2907-1999. In the Defect System standard, coffee bean is classified into six grades, from grade I to grade VI depending on the number of defect found in the coffee bean. Accuracy of this method heavily depends on the experience and the expertise of the human operators. The objective of the research is to develop a system to determine the coffee bean grading based on SNI No: 01-2907-1999. A visual sensor, a webcam connected to a computer, was used for image acquisition of coffee bean image samples, which were placed under uniform illumination of 414.5+2.9 lux. The computer performs feature extraction from parameters of coffee bean image samples in the term of texture (energy, entropy, contrast, homogeneity and color (R mean, G mean, and B mean and determines the grade of coffee bean based on the image parameters by implementing neural network algorithm. The accuracy of system testing for the coffee beans of grade I, II, III, IVA, IVB, V, and VI have the value of 100, 80, 60, 40, 100, 40, and 100%, respectively.

    2016-01-01

    The common bean is an important component in the diet of the average Brazilian person. Each harvest of beans, losses occur due to attacks of insects and rodents. One of the ways to preserve the beans, and at the same time keep its nutritional characteristics, is the use of gamma radiation. This study aimed to evaluate the effects of different doses of gamma radiation on the physical and chemical properties of the carioca variety of common beans subject to cooking of soaked and unsoaked beans. Portions of raw beans were used as control and the other was subject to ionizing radiation at doses of 1, 5 and 10 kGy. Following irradiation, a portion of the samples (control and irradiated) were soaked and the other was not, then all beans were cooked. The cooked samples were lyophilized, milled and then accommodated in pots and stored at -23 deg C temperatures. The analysis of chemical composition, determination of protein digestibility, condensed tannin and phytic acid content were performed using the milled samples. Using whole grains, were performed analysis of expansion capability and hydration, cooking time and instrumental color. Irradiation did not alter the chemical composition of soaked and unsoaked samples. The condensed tannin levels did not reduce according to increased doses. The phytic acid concentrations were reduced at the doses of 5 and 10 kGy for soaked samples, whereas for the not soaked beans, gamma irradiation did not influence the phytate content. The protein digestibility decreased on soaked samples, at doses of 1 kGy and in the other doses, the reduction was not significant. As for not soaked beans, increases in digestibility were observed at dose of 10 kGy. As the doses increased, reduction in cooking time on soaked and unsoaked beans was noted. At a dose of 10 kGy, the bean expansion capability increased. The samples' color did not change significantly, as the doses increased. Therefore, it is concluded that ionizing radiation has no effect

    Descending necrotizing mediastinitis (DNM) is a rare form of mediastinal infection. Most cases are associated with esophageal rupture. DNM after a trigger point injection in the upper trapezius has not been described previously. We present a case of DNM after a trigger point injection in the upper trapezius. A 70-year-old man visited the emergency department with chest discomfort and fever after a trigger point injection in the left upper trapezius. Chest computed tomography showed evidence of DNM, and antibiotic therapy was immediately administered intravenously. Because of the risk of sudden death, poor prognosis due to underlying disease, and his age, he declined surgical treatment and died of septic shock. Although trigger point injections are generally considered safe, caution should be used in patients with an underlying disease or in the elderly. Early diagnosis, broad-spectrum antibiotics, and aggressive surgical management are essential to improve the prognosis.

    2008-01-01

    Full Text Available Necrotizing fasciitis (NF of the face and neck is a very rare complication of dental infection. Otolaryngologists and dentists should be familiar with this condition because of its similarity to odontogenic deep neck space infection in the initial stages, its rapid spread, and its life-threatening potential. Trauma has been reported to be an important predisposing factor for NF of the face. In this paper, we describe the presentation and treatment of a 62-year-old man who developed NF of the face and neck following bilateral odontogenic deep neck space abscesses. The disease progressed rapidly, with necrosis of the skin, after the patient inflicted minor trauma in the form of application of heated medicinal leaves. The organism isolated in culture from pus was Acinetobacter sp . The comorbid conditions in our patient were anemia and chronic alcoholism. The patient was managed by immediate and repeated extensive debridements and split-skin grafting.

    2016-09-01

    Full Text Available Deep neck infection is a potentially life-threatening disease, especially complicated with descending necrotizing mediastinitis (DNM. The mean age of DNM is 49–57.8 years old. The commonly seen causes are tonsillar, pharyngeal infection and odontogenic origins. When the deep neck infection extended to the mediastinal spaces, the pleural effusion or pericardial effusion may appear. Here is a rare young lady who had fever and sore throat for 2 weeks, and chest X-ray showed bilateral pleural effusion. After surgical drainage, the Escherichia coli grew over the culture of pericardial effusion. This case is rarely seen in the presence of Escherichia coli pyopericardium originating from DNM in the past. Overall mortality rate of DNM is around 11.2%–17% nowadays. We should keep in mind that for DNM, early diagnosis and aggressively surgical intervention with suitable drainage, and intensive postoperative care should be conducted to lower the morbidity and mortality.

    Full Text Available Necrotizing enterocolitis (NEC is among the most common and devastating diseases in neonates and, despite the significant advances in neonatal care and clinical and basic science investigations, its etiology remains incompletely understood, specific treatment strategies are lacking, and morbidity and mortality from this disease remain high. Recent improvements in the pathophysiology of NEC may have therapeutic consequences. Toll-like receptors and intestinal microflora play an increasing role in the pathogenesis of NEC. Pharmacologic inhibition of TLR signaling, the use of novel nutritional strategies, and microflora modulation may represent novel promising approaches to the prevention and treatment of NEC. This review focuses on current and future therapeutic perspectives, starting from the recent acquisitions in the pathogenic mechanisms of NEC. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Systemic lupus erythematosus (SLE) is a multisystemic disease with varied clinical manifestations. Focal cortical brain infarcts and CNS infections are the most common neuropathological features reported in most studies. This report describes a 32-year-old woman who had repeated episodes of strokes over 5 years. In view of polyarthritis, oral ulcers, presence of high titres of serum antinuclear antibodies, high titres of double-stranded DNA and strokes, she was treated as SLE. Despite prolonged immunosuppressive therapy with azathioprine and pulse cyclophosphamide, she succumbed to a brainstem stroke. Complete body autopsy showed multiple cerebral cortical and brainstem infarcts with fibrinoid necrosis of the vessel wall. Renal infarction with healed vasculitis and systemic vasculitis involving small vessels was seen. Extensive thrombosis was remarkable by its absence. Active necrotizing vasculitis of cerebral and renal vessels is a rare complication of SLE, which contributed to a fatal outcome in this patient.

    2008-04-01

    Based on the demonstration of coagulation necrosis, it is clear that intestinal ischemia plays a role in the pathogenesis of necrotizing enterocolitis (NEC). Intestinal vascular resistance is determined by a dynamic balance between vasoconstrictive and vasodilatory inputs. In the newborn, this balance heavily favors vasodilation secondary to the copious production of endothelium-derived nitric oxide (NO), a circumstance which serves to ensure adequate blood flow and thus oxygen delivery to the rapidly growing intestine. Endothelial cell injury could shift this balance in favor of endothelin (ET)-1-mediated vasoconstriction, leading to intestinal ischemia and tissue injury. Evidence obtained from animal models and from human tissue collected from infants with NEC implicates NO and ET-1 dysregulation in the pathogenesis of NEC. Strategies focused on maintaining the delicate balance favoring vasodilation in the newborn intestinal circulation may prove to be useful in the prevention and treatment of NEC.

    2014-10-01

    Full Text Available Background: We report a case of necrotizing keratitis caused by acyclovir (ACV-resistant herpes simplex virus (HSV with a clinical appearance similar to a previous fungal keratitis infection. Methods: Observational case report. Results: Penetrating keratoplasty was performed in the left eye with a history of herpetic keratitis that resolved with periodic treatment with ACV ointment and a topical steroid. The left eye was painful and red with an abscess and corneal erosion in the peripheral donor cornea. Examination of the scraped corneal epithelium by light microscopy and culturing identified Candida albicans; polymerase chain reaction (PCR was negative for human herpes viruses. After antifungal treatment, the ocular pain gradually decreased and the lesions slowly improved but recurred with a similar clinical appearance. A second light microscopy examination and cultures were negative for pathogens including C. albicans. PCR was positive for HSV-1 DNA; treatment with 3% topical ACV ointment was unsuccessful. A third examination showed only HSV-1 DNA. Despite antiviral ACV ointment, no clinical improvement occurred based on the HSV DNA copy numbers, which were the same before and after treatment, indicating a possible ACV-resistant strain. When topical trifluorothymidine was substituted for ACV, clinical improvement occurred and the HSV DNA copy numbers decreased. Conclusion: Necrotizing keratitis induced by ACV-resistant HSV occurred independently after fungal keratitis, with a similar clinical appearance in this case, making diagnosis and treatment difficult. Monitoring the HSV DNA load by real-time PCR could be useful for refractory cases even with atypical clinical appearances.

    Water security is an important basis for making water security protection strategy, which concerns regional economic and social sustainable development. In this paper, watershed water security evaluation index system including 3 levels of 5 criterion layers (water resources security, water ecological security and water environment security, water disasters prevention and control security and social economic security) and 24 indicators were constructed. The entropy weight method was used to determine the weights of the indexes in the system. The water security index of 2000, 2005, 2010 and 2015 in Yellow River basin were calculated by linear weighting method based on the relative data. Results show that the water security conditions continue to improve in Yellow River basin but still in a basic security state. There is still a long way to enhance the water security in Yellow River basin, especially the water prevention and control security, the water ecological security and water environment security need to be promoted vigorously.

    Full Text Available The methodology of sensory profiling constitutes the basis of a descriptive quantitative analysis, defining a product with the minimum number of words and with maximum efficiency, using a precise tasting sheet, which can be reproduced and is understood by all. In this work, the texture profiling for different bean varieties that are characteristic of the Spanish market was carried out. Optimum conditions for samples and a tasting card were established, and a panel was trained. The texture profile results show significant differences amongst varieties and even amongst different origins for the same variety.

    The frequency and spectrum of M2 chlorophyll and other leaf mutations after gamma ray, ethyl methane sulfonate (EMS) and nitrous oxide (N2O) seed treatment in two varieties of faba bean were studied. In general, cv JV1 was more sensitive and EMS treatment was most effective. The frequency of chlorina-type mutations was higher than that of xantha and chlorotica type chlorophyll mutations. The highest frequency of variations was observed in leaflet texture, followed by arrangement, shape and size in both varieties. The use of these leaf mutations in formulating an ideotype of Vicia faba L. are discussed

    Fava beans are eaten all over the world and recently, marketing for their sprouts began in Japan. Fava bean sprouts contain more polyphenols and l-3,4-dihydroxyphenylalanine (l-DOPA) than the bean itself. Our antioxidant screening program has shown that fava bean sprouts also possess a higher antioxidant activity than other commercially available sprouts and mature beans. However, the individual constituents of fava bean sprouts are not entirely known. In the present study, we investigated the phenolic compounds of fava bean sprouts and their antioxidant activity. Air-dried fava bean sprouts were treated with 80% methanol and the extract was partitioned in water with chloroform and ethyl acetate. HPLC analysis had shown that the ethyl acetate-soluble parts contained phenolic compounds, separated by preparative HPLC to yield 5 compounds (1-5). Structural analysis using NMR and MS revealed that the compounds isolated were kaempferol glycosides. All isolated compounds had an α-rhamnose at the C-7 position with different sugars attached at the C-3 position. Compounds 1-5 had β-galactose, β-glucose, α-rhamnose, 6-acetyl-β-galactose and 6-acetyl-β-glucose, respectively, at the C-3 position. The amount of l-DOPA in fava bean sprouts was determined by the quantitative (1) H NMR technique. The l-DOPA content was 550.45 mg ± 11.34 /100 g of the raw sprouts. The antioxidant activities of compounds 2-5 and l-DOPA were evaluated using the 2,2-diphenyl-1-picrylhydrazyl scavenging assay. l-DOPA showed high antioxidant activity, but the isolated kaempferol glycosides showed weak activity. Therefore, it can be suggested that l-DOPA contributed to the antioxidant activity of fava bean sprouts. © 2016 Institute of Food Technologists®

    Vegetable proteins are an integral part of infant weaning diets in Latin America. Protein quality in plant-based products, however, is constrained by amino acid composition and intrinsically present antinutritional factors. The goal of this study was to improve bean protein quality by utilizing fermentation and germination processing. The objectives were to determine if protein quality, as measured by Food and Agricultural Organization (FAO) approved True Protein Digestibility (TPD) and Protein Digestibility-Corrected Amino Acid Scores (PDCAAS), of formulated bean-based weaning products could be improved upon fermentation and germination and if protein quality could be further improved when processed beans were combined with cooked rice. Results showed that the highest TPD and PDCAAS values were obtained for cooked germinated beans combined with rice. The TPD values for products ranged from 80 to 91%, and the PDCAAS values were 0.38-0.51. There was no significant increase (P PDCAAS values upon fermentation. Germination increased TPD of cooked bean products; this increase was not, however, accompanied by an increase in PDCAAS. When combined with rice, the PDCAAS values for all bean products improved significantly, thus supporting the concept of cereal-legume complementation. In conclusion, this study showed the range of PDCAAS in processed black bean and bean-rice infant weaning food products. The potential for incorporation of these products into the diets of weaning age Latin American children would, however, be confirmed only after validation with growth or metabolic balance studies in human infants.

    Dengue virus three, Chikunguya and Zika have entered the national territory through the south of the country. Cases and outbreaks of yellow fever have now been identified in the Americas where it threatens to expand. Although Mexico has a robust epidemiological surveillance system for vector-borne diseases, our country must be alert in case of its possible introduction into the national territory. This paper presents theoretical assumptions based on factual data on the behavior of yellow fever in the Americas, as well as reflections on the epidemiological surveillance of vector-borne diseases.

    (Phaseolus vulgaris). The hardening of Phaseolus vulgaris beans stored at high temperature and high relative humidity is one of the main constraints for consumption. The objective of this research was to evaluate by scanning electron microscopy, structural changes in cotyledons and testa of the hardened beans. The freshly harvested grains were stored for twelve months under two conditions: 5 ° C-34% RH and 37 ° C-75% RH, in order to promote hardening. The stored raw and cooked grains were lyophilized and fractured. The sections of testa and cotyledons were observed in an electron microscope JSM-6390. After twelve months, grains stored at 37 ° C-75% RH increased their hardness by 503%, whereas there were no significant changes in grains stored at 5 ° C-34% RH. At the microstructural level, the cotyledons of the raw grains show clear differences in appearance of the cell wall, into the intercellular space size and texture matrix protein. There were also differences in compaction of palisade and sub-epidermal layer in the testa of raw grains. After cooking, cotyledon cells of the soft grains were well separated while these ofhard grains were seldom separated. In conclusion, the found differences in hard and soft grains showed a significant participation of both structures, cotyledons and testa, in the grains hardening.

    We report the case of a 74-year-old female who developed a necrotizing sclerokeratitis affecting her left eye after uncomplicated cataract surgery. She had no previous history of systemic autoimmune disease. Histopathology of the lesion revealed necrotic granulomatosis with an increased number of plasma cells. Surgically induced necrotizing sclerokeratitis (SINS) is a serious entity which requires prompt and aggressive therapy to prevent its potential devastating ocular consequences. Conjunctival resection and amniotic membrane grafting may be necessary to temporarily interrupt local immunologic events in severe cases. However, associated systemic immunomodulatory therapy seems to be mandatory (Arch Soc Esp Oftalmol 2009; 84: 577-580).

    Full Text Available Inflammatory myopathies such as dermatomyositis and polymyositis are well-recognized paraneoplastic syndromes. Little is known, however, about necrotizing myopathies in association with cancer. We here describe a case of paraneoplastic necrotizing myopathy with a mild inflammatory infiltrate in a patient with adenocarcinoma. After the rapid development of a severe, disabling muscle weakness, the patient experienced near complete recovery within 4 months under oral prednisone treatment. In the context of the presented case, we will review current knowledge about paraneoplastic necrotizing myopathies.

    Full Text Available Necrotizing fasciitis is a rare and life-threatening soft tissue infection that spreads rapidly and involves the skin, subcutaneous tissue, fascia, and muscle layer. The treatment is possible by initiating appropriate antibiotherapy for the clinically suspected cause and by performing surgical intervention quickly and aggressively. However, it should be known that necrotizing fasciitis is a disease that is difficult to manage despite all interventions, effective treatment protocols, and patient care. This article presents the case of a 60-year-old patient with diabetes mellitus who died of toxic shock syndrome with fulminant necrotizing fasciitis caused by Streptococcus agalactiae.

    Coffee organoleptic properties are based in part on the quality and chemical composition of coffee beans. The presence of defective beans during processing and roasting contribute to off flavors and reduce overall cup quality. A multipronged approach was undertaken to identify specific biochemical markers for defective beans. To this end, beans were split into defective and non-defective fractions and biochemically profiled in both green and roasted states. A set of 17 compounds in green beans, including organic acids, amino acids and reducing sugars; and 35 compounds in roasted beans, dominated by volatile compounds, organic acids, sugars and sugar alcohols, were sufficient to separate the defective and non-defective fractions. Unsorted coffee was examined for the presence of the biochemical markers to test their utility in detecting defective beans. Although the green coffee marker compounds were found in all fractions, three of the roasted coffee marker compounds (1-methylpyrrole, 5-methyl- 2-furfurylfuran, and 2-methylfuran) were uniquely present in defective fractions.

    Full text: The gravimetric analysis of uranium in yellow cake is composed of several stages. The analysis takes a long time, which is the disadvantage of this method. However, this gravimetric method provides accurate result for determining the major content of sample. Uranium is the main composition of yellow cake, while Thorium, rare earths and other elements are minor and trace elements. In this work, anion exchange resin was used to separate uranium from other elements to yield highly pure uranium suitable for precipitation. This pure uranium was burnt to U3O8, a form that is stable enough to be weighed. From the optimal condition, the recovery of U3O8 after separating uranium from rare earths and iron is 99.85 ± 0.21%. The application of anion exchange separation was used to analyze uranium in yellow cake obtained from monazite digestion process. It was found that U3O8 in yellow cake is 78.85 ± 2.03%

    An outbreak of a devastating virus disease occurred in common ben (phaseolus vulgaris) in Berber area, the River Nile State, during the 2004/2005 cropping season, with symptoms of stunting and yellowing. The disease incidence reached a level of more than 85% in all visited fields. One hundred fifty symptomatic samples, collected from different fields at Hudeiba, Berber and Shendi were blotted on nitrocellulose membranes and tested for the presence of different viruses, using the tissue blot immunoassay (TBIA) technique. The results of the serological tests revealed that 95% of the samples were positive for cowpea mild mottle virus (CPMMV). Among the common bean genotypes screened for resistance to CPMMV, only RO/2/1 and Giza 3 were resistant to the disease.(Author)

    Wild accessions of crops and landraces are valuable genetic resources for plant breeding and for conserving alleles and gene combinations in planta. The primary genepool of cultivated common beans includes wild accessions of Phaseolus vulgaris. These are of the same species as the domesticates and therefore are easily crossable with cultivated accessions. Molecular marker assessment of wild beans and landraces is important for the proper utilization and conservation of these important genetic resources. The goal of this research was to evaluate a collection of wild beans with fluorescent microsatellite or simple sequence repeat markers and to determine the population structure in combination with cultivated beans of all known races. Marker diversity in terms of average number of alleles per marker was high (13) for the combination of 36 markers and 104 wild genotypes that was similar to the average of 14 alleles per marker found for the 606 cultivated genotypes. Diversity in wild beans appears to be somewhat higher than in cultivated beans on a per genotype basis. Five populations or genepools were identified in structure analysis of the wild beans corresponding to segments of the geographical range, including Mesoamerican (Mexican), Guatemalan, Colombian, Ecuadorian-northern Peruvian and Andean (Argentina, Bolivia and Southern Peru). The combined analysis of wild and cultivated accessions showed that the first and last of these genepools were related to the cultivated genepools of the same names and the penultimate was found to be distinct but not ancestral to the others. The Guatemalan genepool was very novel and perhaps related to cultivars of race Guatemala, while the Colombian population was also distinct. Results suggest geographic isolation, founder effects or natural selection could have created the different semi-discrete populations of wild beans and that multiple domestications and introgression were involved in creating the diversity of cultivated beans

    Full Text Available Paleobiolinguistics is used to determine when and where the common bean (Phaseolus vulgaris L. developed significance for prehistoric groups of Native America. Dates and locations of proto-languages for which common bean terms reconstruct generally accord with crop-origin and dispersal information from plant genetics and archaeobotany. Paleobiolinguistic and other lines of evidence indicate that human interest in the common bean became significant primarily with the widespread development of a village‐farming way of life in the New World rather than earlier when squash and maize and a few other crops became important.

    Full Text Available Aim: To know whether laboratory or clinical parameters can predict disease progression, need for laparotomy in patients managed with peritoneal drain and mortality in surgical neonatal necrotizing enterocolitis patients. Materials and Methods: The study was retrospectively carried out on 27 neonates over a period of one and a half year. All neonates who had surgical neonatal necrotizing enterocolitis in the form of bowel perforation, positive paracentesis, abdominal wall erythema and abdominal lump were included. Patients with Bell′s stage I and those developing enterocolitis after surgery were excluded. The patients were evaluated with parameters, namely, clinical, laboratory and radiological. These included age and stage at presentation, primary symptom/sign at presentation with laboratory parameters of blood counts, pH, base deficit, platelet counts, electrolytes and random blood sugar levels. A comparison was done between survivors and nonsurvivors, patients with primary peritoneal drainage versus those requiring laparotomy after drain, Bell′ stage II versus III patients and operated versus nonoperated patients. Statistical significance was observed in the above mentioned comparisons. Results: There were 22 male and 5 females patients with mean birth weight of 1.85 kg. Age at presentation ranged from 2 to 19 days, mean 9.25 days. Mortality was 37% (10/27. Majority of the stage II patients presented with feed intolerance and abdominal distension. The neonates with severe disease had abdominal distension with wall erythema. Sixty percent of the patients had shock at the time of admission. In the comparison of peritoneal drain only and patients with peritoneal drain followed by laparotomy patients, it was observed that neonates who were acidotic and had higher base deficit had more chances of requirement of laparotomy. They also had progressive fall in platelets counts. There was no difference in the birth weight, gestational age, total

    Full Text Available Changes in anatomy and cytology of conducting tissues of Limonium sinuatum Mill. plants affected by aster yellows phytoplasma were investigated. In the phloem tissues of affected plants stem necrosis takes place. In necrotic regions no sieve tubes were observed only necrotic cells and parenchyma cells. The sieve tubes present on the border of necrosis showed collapsed walls and were rich in vesicles. Phytoplasma cells were observed in sieve tubes present in nonnecrotic regions of the phloem. Various structural changes in sieve elements were investigated. The endoplasmic reticulum cistemae were often localised in the lumen of the sieve element without contact with the walls. Such localisation of endoplasmic reticulum was never observed in healthy plants. Vesicles of different size, fuzzy material and clumping of p-proteins were characteristic for sieve elements from nonnecrotic part of phloem. No correlation with the sieve tube structure and the appearance of phytoplasma in a single sieve element was found. In control plants of L. sinuatum phloem observed were phloem parenchyma cells with spiny vesicles (SV. In infected plants there were a remarkable increase in cells with SV. Also the SV itself had not only a vesicular but also a tubular or extended cistern shape.

    Vicia faba L, is a globally important grain legume whose main centers of diversity are the Fertile Crescent and Mediterranean basin.

    1988-01-01

    Dock workers (n = 218) occupationally exposed to green coffee beans (GCB) were studied, using a specific questionnaire for allergic symptoms and skin tests for common and occupational allergens. Thirty-one workers (14.3%) complained of allergic symptoms of the eye, nose and bronchial system at the workplace. The prick tests, using both commercial allergens and specific extracts prepared from the most common types of coffee and their corresponding sacks, confirmed a sensitization in 21 workers (9.6%). A positive skin reaction to castor beans (CB) was found in nearly all these cases; in ten workers there was also a positive reaction to GCB allergens and in 14 cases prick tests were positive to extracts of sacks. There was a good concordance between prick tests and specific IgE for CB (95.0%) and also, but to a lesser extent, for GCB. The authors concluded that there is a significant risk of sensitization to CB and GCB allergens in dock workers occupied in handling green coffee bean, despite the fact that the exposure is not continuous. CB emerged as a common contaminant of GCB from various countries. For effective prevention, a modification of the methods of transport is required to avoid CB contamination to other products. Eliminating environmental dust during shipping operations is the most important preventive measure and it can be achieved by the use of containers, as some exporting countries are already doing.

    Objective: To investigate the value of diffusion weighted imaging (DWI)on brain abscess and necrotic or cystic brain tumors. Methods: 27 cases with brain abscesses and 33 cases with necrotic or cystic brain tumors (gliomas or metastases) were performed conventional MRI and DWI. Apparent diffusion coefficient (ADC) of region of interest (ROI) was measured and statistically tested. Sensitivity and specificity were calculated and compared with conventional MR and DWI. Results: Hyperintensity signal was seen on most brain abscesses. All necrotic or cystic brain tumors showed hypointensity signal on DWI. There was statistical significance on ADC of them. The sensitivity and specificity of conventional MRI was lower than that of DWI. Conclusion: DWI and ADC were useful in distinguishing brain abscessed from necrotic or cystic brain tumors, which was important in addition to conventional MRI. (authors)

    Full Text Available Abstract Introduction Necrotizing fasciitis is a rare and life-threatening rapidly progressive soft tissue infection. A fulminant case could involve muscle and bone. Necrotizing fasciitis after corticosteroid therapy and intramuscular injection of non-steroidal anti-inflammatory drugs has been reported. We present a case of fulminant necrotizing fasciitis occurring in a patient who used a herbal concoction to treat a chronic leg ulcer. Case presentation A 20-year-old Ibo woman from Nigeria presented with a three-year history of recurrent chronic ulcer of the right leg. She started applying a herbal concoction to dress the wound two weeks prior to presentation. This resulted in rapidly progressive soft tissue necrosis that spread from the soft tissue to the bone, despite aggressive emergency debridement. As a result she underwent above-knee amputation. Conclusion The herbal concoction used is toxic, and can initiate and exacerbate necrotizing fasciitis. Its use for wound dressing should be discouraged.

    Full Text Available Necrotizing fasciitis is a life-threatening, soft tissue infection and an early diagnosis is needed to permit a prompt surgical and medical intervention. Due to the high fatal potential of the disease complications, the radiologist should distinguish necrotizing fasciitis from the most common soft tissue infections, in order to permit a prompt surgical and medical treatment. We present a case of a wide necrotizing fasciitis who presented at our emergency department and we also provide the basic tools, through a review of the literature, for the general radiologist to distinguish, with computed tomography and magnetic resonance imaging, necrotizing fasciitis from the most common infections that could present during our routine practice.

    2013-10-01

    Full Text Available Human cases of brucellosis are rare in the United States and difficult to diagnose. We report a case of a young female who underwent a diagnostic investigation of fever of unknown origin, which included a lymph node biopsy. The biopsy was consistent with Kikuchi’s Disease, or histiocytic necrotizing lymphadenitis, an entity where the major differential diagnosis is systemic lupus erythematosus. Interestingly, serologic studies supported the diagnosis of brucellosis. Brucellosis has rarely been associated with histiocytic necrotizing lymphadenitis. This association has never been reported in the United States, thus suggesting that brucellosis should be considered in the differential for histiocytic necrotizing lymphadenitis, along with lupus-like autoimmune disease. As the prognosis and treatment of histiocytic necrotizing lymphadenitis, brucellosis, and systemic lupus erythematosus are distinct, it is important to differentiate these entities.

    Full Text Available Pectinase enzyme of coffee pericarp, containing pectinesterase and polymetilesterase, is potential to determine harvesting time or to classify coffee beans. The activity of the enzyme on the green fruit is higher than on the yellow one. When the fruit become light red, the activity increaed for the second time and then decrease when the fruit is overripe (dark coloredThe optimum fermentation condition of the fruit is depending on the maturation degree. Study on the fermentation process at 25oC, suggest sorting of harvesting fruits in three groups. (1 fruits are harvested 9-24 days after the fruits reach its yellowish green color, Ao, (2 25 - 32 days after Ao, and (3 33 - 38 days after Ao.Fermenting at 35o C grouping into four types of maturation degree. (1 9 - 11 days after Ao, (2 12 - 22 days after Ao, (3 23 - 30 days after Ao, and (4 24-36 days after Ao. The optimum harvesting time is when the beans reach light red until the color starts getting dark. The optimum activity of the enzyme pectinase is at 35oC.

    The common bean is a staple crop in many African and Latin American countries and is the focus of biofortification initiatives. Bean iron concentration has been doubled by selective plant breeding, but the additional iron is reported to be of low bioavailability, most likely due to high phytic acid (PA) concentrations. The present study evaluated the impact of PA on iron bioavailability from iron-biofortified beans. Iron absorption, based on erythrocyte incorporation of stable iron isotopes, was measured in 22 Rwandese women who consumed multiple, composite bean meals with potatoes or rice in a crossover design. Iron absorption from meals containing biofortified beans (8.8 mg Fe, 1320 mg PA/100 g) and control beans (5.4 mg Fe, 980 mg PA/100 g) was measured with beans containing either their native PA concentration or with beans that were ∼50% dephytinized or >95% dephytinized. The iron concentration of the cooked composite meals with biofortified beans was 54% higher than in the same meals with control beans. With native PA concentrations, fractional iron absorption from the control bean meals was 9.2%, 30% higher than that from the biofortified bean meals (P bean meals (406 μg) was 19% higher (P bean meals. With ∼50% and >95% dephytinization, the quantity of iron absorbed from the biofortified bean meals increased to 599 and 746 μg, respectively, which was 37% (P bean meals. PA strongly decreases iron bioavailability from iron-biofortified beans, and a high PA concentration is an important impediment to the optimal effectiveness of bean iron biofortification. Plant breeders should focus on lowering the PA concentration of high-iron beans. This trial was registered at clinicaltrials.gov as NCT01521273. © 2014 American Society for Nutrition.

    We report the case of a 45-year-old Colombian female with a 3-month history of headache, anorexia, fatigue, and diplopia in addition to left facial nerve palsy 2 weeks prior to presentation. On examination, visual fields and fundi were normal, but left abducens and facial nerve palsies were noted. An MRI scan disclosed a sellar mass with suprasellar but neither parasellar nor retrosellar extension. The mass was interpreted as a pituitary tumor and resected via the transsphenoidal approach. Histologic examination revealed necrotizing granulomas in a background of normal pituitary gland tissue. The differential diagnosis includes tuberculosis, sarcoidosis, fungal infection, syphilis, granulomatous autoimmune hypophysitis, Langerhans cell histiocytosis, and Erdheim-Chester disease. Staining for tubercle bacilli (acid fast and fite) as well as for fungi (GMS) was negative and PCR for mycobacteria showed the same result. Postoperative empiric treatment with antituberculous medication resulted in resolution of the cranial nerve palsies within a 1 month. The diagnosis of inflammatory/infectious granulomatous hypophysitis can be difficult to diagnose preoperatively and occasionally even postoperatively. A high index of suspicion should be maintained especially in those patients with a history of a systemic granulomatous disease or in regions endemic in granulomatous infectious diseases.

    Through a 10-year retrospective study, we report our experience in the management of descending necrotizing mediastinitis (DNM), a rare and often lethal complication of odontogenic and oropharyngeal infections. We reassessed 23 patients between the ages of 16 and 69 years (mean, 49 years) seen between 1996 and 2005, with DNM secondary to odontogenic abscess or phlegmon in 9 cases or secondary to peritonsillar abscess in 14 cases. In this study, 48% of the patients had immune system disorders, mainly diabetes mellitus (6 patients). The diagnosis of DNM was confirmed by cervicothoracic computed tomography. Eight patients underwent a bilateral collar cervicotomy, and 15 underwent a combined cervicothoracic approach. Five, 2, 1, and 1 patients underwent surgery 2, 3, 4, and 5 times, respectively. Seven patients died as a result of septic shock and multiorgan failure, for a mortality rate of 30.4%. Four of those who died had a compromised immune system. The relatively high mortality rate seen in this study shows that, in addition to early diagnosis and aggressive treatment, it is important to give greater attention to and be more medically and surgically aggressive in the management of patients whose immune system is compromised in any way.

  10. Human milk is the feeding strategy to prevent necrotizing enterocolitis!

    Maffei, Diana; Schanler, Richard J

    2017-02-01

    Human milk is the preferred diet for preterm infants as it protects against a multitude of NICU challenges, specifically necrotizing enterocolitis. Infants who receive greater than 50% of mother's own milk (MOM) in the 2 weeks after birth have a significantly decreased risk of NEC. An additional factor in the recent declining rates of NEC is the increased utilization of donor human milk (DHM). This creates a bridge until MOM is readily available, thus decreasing the exposure to cow milk protein. Preterm infants are susceptible to NEC due to the immaturity of their gastrointestinal and immune systems. An exclusive human milk diet compensates for these immature systems in many ways such as lowering gastric pH, enhancing intestinal motility, decreasing epithelial permeability, and altering the composition of bacterial flora. Ideally, preterm infants should be fed human milk and avoid bovine protein. A diet consisting of human milk-based human milk fortifier is one way to provide the additional nutritional supplements necessary for adequate growth while receiving the protective benefits of a human milk diet.

    1998-04-01

    Chronic necrotizing pulmonary aspergillosis (CNPA) is a chronic pulmonary infection caused by the genus Aspergillus, which usually involves moderately immunosuppressed patients. We describe 3 patients with a toxic syndrome that had lasted several weeks or months, with lung infiltrates in the chest X-ray and the CT scan. Mycobacterium tuberculosis could not be isolated from different respiratory smears (sputum, bronchoaspiration, Barlett catheter and pulmonary punction in the third case). Moreover, there was no response to anaerobic treatment. All 3 patients were moderately immunosuppressed (2 men were COPD and the woman was an asthmatic patient). One of the men was being treated for a nocardiosis. In all three cases, A. fumigatus was isolated from de different respiratory smears. To diagnose a CPNA, a high degree of clinical suspicion is needed. The differential diagnose should be done with pulmonary tuberculosis and anaerobic infections. The presence of a member of the genus Aspergillus in the tracheobronchial secretions of a patient should not be systematically considered a saprofit, specially when other microorganisms can not be isolated.

    Full Text Available Background: Necrotizing soft tissue infections (NSTI are potentially severe infections that have a high morbidity and mortality even with modern medical care. This study examines factors associated with outcomes in patients with NSTI in an academic tertiary care hospital. Design: This is a retrospective cohort study of patients admitted with NSTI between 2003 and 2008. Baseline demographics and comorbid conditions, laboratory and clinical parameters, timing of surgery, and outcomes, including length of stay and mortality, were compared with univariate analysis; significant factors were then analyzed for their effects on mortality using binary logistic regression analysis. Results: Sixty-nine patients with NSTI were analyzed; 61% were men. Diabetes (39% was the most common comorbid condition. Most infections (55% were polymicrobial. The most common organism in monomicrobial infections was Staphylococcus aureus, and 50 % of these isolates were methicillin resistant. Nine patients (13% required amputation. Mortality was 20%, and the most significant predictor of mortality was a higher respiratory rate on admission (p=0.02. Conclusion: Patients in this series frequently had diabetes, usually had polymicrobial infections, and had a 20% mortality rate.

    Full Text Available Cervical necrotizing fasciitis (NF is a soft tissue infection with a low incidence, characterized by rapid progression and high morbidity and mortality. The purpose of this report is to communicate the case of a patient diagnosed with cervical NF and its successful management. A 54-year-old male consulted after suffering from the condition for seven days. It was characterized by bilateral submandibular swelling, accompanied by fever, dysphagia, odynophagia, which were severely affecting the patient’s general health. Physical examination revealed a painful, erythematous cervical swelling. A cervical computed tomography scan was performed, revealing a gaseous collection in the left mucosal pharyngeal space, extending to the glottis, associated with significant deep plane soft tissue emphysema onon the left side of the neck and with possible involvement of the danger space; pertinent lab findings include 19,190/uL leukocytes and 219mg/L CRP. Broad-spectrum antibiotic therapy was initiated with ceftriaxone and clindamycin. Exploratory surgery, lavage and drainage of the collected material were performed. Streptococcus anginosus was isolated by culture. The patient recovered appropriately showing improvement in clinical as well as in inflammatory parameters, being discharged on the ninth day. He is currently receiving periodical checkups in the surgery polyclinic.

    2013-01-01

    Full Text Available Adenoviruses (AdV are emerging pathogens with a prevalence of 11% viruria and 6.5% viremia in kidney transplant recipients. Although AdV infection is common, interstitial nephritis (ADVIN is rare with only 13 biopsy proven cases reported in the literature. We report a case of severe ADVIN with characteristic histological features that includes severe necrotizing granulomatous lesion with widespread tubular basement membrane rupture and hyperchromatic smudgy intranuclear inclusions in the tubular epithelial cells. The patient was asymptomatic at presentation, and the high AdV viral load (quantitative PCR>2,000,000 copies/mL in the urine and 646,642 copies/mL in the serum confirmed the diagnosis. The patient showed excellent response to a combination of immunosuppression reduction, intravenous cidofovir, and immunoglobulin therapy resulting in complete resolution of infection and recovery of allograft function. Awareness of characteristic biopsy findings may help to clinch the diagnosis early which is essential since the disseminated infection is associated with high mortality of 18% in kidney transplant recipients. Cidofovir is considered the agent of choice for AdV infection in immunocompromised despite lack of randomized trials, and the addition of intravenous immunoglobulin may aid in resolution of infection while help prevention of rejection.

    Necrotizing fasciitis (NF) of the face is a rare but extremely dangerous complication of dental infection associated with a nearly 30% mortality rate. This infection spreads rapidly along the superficial fascial planes of the head and neck and can lead to severe disfigurement. Reports in the literature of cases of NF of the face caused by dental infection are few. We report such a case in a 36-year-old woman and review the current standards of diagnosis and management. The patient initially presented with pain and severe swelling in the left side of her face subsequent to a dental infection. The symptoms had progressed quickly and had not improved with administration of oral antibiotics in the outpatient setting. The patient had no palpable crepitus despite its classic association with NF. The infection also took a rare, ascending route of spread with involvement of the temporalis muscle. Cultures taken during debridement grew Streptococcus anginosus and Bacteroides. Biopsies of involved muscle showed histologic evidence of necrosis. Through early surgical intervention including aggressive debridement, and the adjunctive use of appropriate antibiotics, the patient recovered with minimal loss of facial mass and no skin loss. Although NF of the face is rare, the surgeon must maintain a high index of suspicion with any patient presenting after a dental infection with rapid progression of swelling and a disproportionate amount of pain that is unresponsive to antibiotics.

    A preliminary experiment was conducted to evaluate the radiosensitivity of common bean (Phaseolous vulgaris L.), cultivar to gamma rays from a 60 Co source. Sets of seeds (60 seed/sample) irradiated with 50, 100, 150, 200, and 250 Gy, were compared to a control without irradiation (0 Gy), under greenhouse conditions. The radiosensitivity was evaluated through seedling height reduction, determined at 15 days after emergence (DAE), and also through seedling survival, root length, and dry matter production of leaves, shoots and roots. Seedling height was significantly reduced for the treatments with 150 and 250 Gy, in relation to the control. The dose causing reduction of 50% seedling height was between 150 and 200 Gy. Survival rates corresponding to these doses, were, respectively, 85% and 60%. Root length and dry matter of leaves, shoots and roots, were inversely related to the doses.

    Full Text Available Necrotizing fasciitis is an uncommon soft-tissue infection, associated with high morbidity and mortality. Early recognition and treatment are crucial for survival. Acinetobacter baumannii is rarely associated with necrotizing fasciitis. Wound infections due to A. baumannii have been described in association with severe trauma in soldiers. There are only sporadic reports of monomicrobial A. baumannii necrotizing fasciitis. We report a unique case of monomicrobial necrotizing fasciitis caused by multidrug resistant (MDR A. baumannii, in absence of any preceding trauma, surgery, or any obvious breech in the continuity of skin or mucosa. A 48-year-old woman with history of HIV, asthma, hypertension, and tobacco and excocaine use presented with acute respiratory failure requiring mechanical ventilation. She was treated for pneumonia for 7 days and was successfully extubated. All septic work-up was negative. Two days later, she developed rapidly spreading nonblanching edema with bleb formation at the lateral aspect of right thigh. Emergent extensive debridement and fasciotomy were performed. Operative findings and histopathology were consistent with necrotizing fasciitis. Despite extensive debridement, she succumbed to septic shock in the next few hours. Blood, wound, and tissue cultures grew A. baumannii, sensitive only to amikacin and polymyxin. Histopathology was consistent with necrotizing fasciitis.

    2013-01-01

    Full Text Available Background. Canine granulomatous scleritis is an uncommon disease that can be classified as necrotizing or non-necrotizing. Clinical signs associated with scleritis are typically severe, resulting in pain and loss of vision, and response to treatment is often poor. Necrotizing scleritis has been previously associated with scleral rupture. Case Presentation. A 10-year-old male castrated Chihuahua was presented for periocular pain, tissue swelling adjacent to the limbus superiorly, chemosis, mild corneal edema and neovascularization adjacent to the superotemporal limbus in the right eye. The left eye was within clinically normal limits. Surgical exploration of the right eye revealed a scleral rupture at the inferonasal aspect of the globe. Histopathology revealed a non-necrotizing granulomatous scleritis with no infectious organisms visualized. Infectious disease testing and special histopathologic staining did not reveal an underlying infectious etiology. Conclusion. Granulomatous scleritis is a painful and vision-threatening disease that needs to be treated early and aggressively in order to avoid loss of vision or loss of the eye. Globe rupture secondary to severe non-necrotizing scleritis is an uncommon, but detrimental, clinical manifestation of this disease. This is the first case report of scleral rupture secondary to severe non-necrotizing scleritis and therefore represents a unique and interesting disease manifestation.

    Full Text Available The coffee germplasm bank of the Instituto Agronômico de Campinas has many Coffea arabica accessions from Ethiopia, which is considered the primary center of genetic diversity in coffee plants. An evaluation of the caffeine content of beans from 99 progenies revealed intra- and inter-progeny variability. In 68 progenies from the Kaffa region we found caffeine values in the range 0.46-2.82% (mean 1.18%, and in 22 progenies from Illubabor region these values ranged from 0.42 to 2.90% (mean 1.10%. This variability could be exploited in a breeding program aimed at producing beans with low-caffeine content.O banco de germoplasma de café do Instituto Agronômico de Campinas contém grande número de introduções de Coffea arabica provenientes da Etiópia, considerada centro de diversidade genética desta espécie.

    The effect of toasting field beans and of grass-clover: maize silage ratio on milk production, milk composition and the sensory quality of the milk was investigated in a 2   2 factorial experiment. Toasting of field beans resulted in lower milk contents of both fat (44.2 versus 46.1 g/kg, P = 0......-β-carotene (P = 0.04) and β-carotene (P = 0.05). Toasting of field beans compared with untreated field beans did not affect the milk content of carotenoids and had only small effects on fatty acid composition. Regarding the sensory quality, the four treatments resulted in milk being characterized...... by a distinctly fatty mouthfeel and creamy flavour and a pronounced sugar-sweet taste and creamy odour. The higher proportions of maize in the feed resulted, in general, in milk characterized by a significantly more intense maize odour (P

    Four major insect pests persistently affect the cocoa industry in Ghana, the world's leading exporter of cocoa, despite the conventional methods of chemical control in practice. The Ghana Atomic Energy Commission currently is investigating the possible use of radiation for the control of both insect attack and microbial spoilage of cocoa beans in storage. Radiation response studies of the four major insect pests that significantly affect the quality of dried cocoa beans in storage have been evaluated. Results herein reported were based on simulated bulk infestation radiation disinfestation of dried cocoa under field and laboratory conditions at ambient temperature (25 to 32 0 C). The comparative efficiency of locally available packaging materials best suited for bagging of the dried cocoa beans at and after irradiation have been assessed concurrently. The author concludes by identifying and discussing possible factors that could affect the technology of radiation disinfestation of cocoa beans under the Ghanaian context. (author)

    Even though the faba bean (Vicia faba L.) is among the most ubiquitously cultivated crops, very little is known about its origins. Here, we report discoveries of charred faba beans from three adjacent Neolithic sites in the lower Galilee region, in the southern Levant, that offer new insights into the early history of this species. Biometric measurements, radiocarbon dating and stable carbon isotope analyses of the archaeological remains, supported by experiments on modern material, date the earliest farming of this crop to ~10,200 cal BP. The large quantity of faba beans found in these adjacent sites indicates intensive production of faba beans in the region that can only have been achieved by planting non-dormant seeds. Selection of mutant-non-dormant stock suggests that the domestication of the crop occurred as early as the 11th millennium cal BP.

    Beans (Phaseolus vulgaris) and peas (Pisum sativum) are important leguminous vegetable crops in Egypt. The area planted with beans is about 40,000 acres and peas 22,000 acres. These crops suffer from several diseases, particularly rusts, (Uromyces phaseoli/Uromyces pisi), which are mainly spread in northern Egypt. In our mutation induction programme we used 60 Co gamma rays and ethyl methane sulphonate (EMS). Bean and pea seeds were soaked in water for two hours before exposure to 8, 10 and 12 krad. For chemical treatments, bean and pea seeds were soaked in water for eight hours and then treated with 0.5 and 1.5% EMS for four hours. The M 1 was cultivated in 1978

    Lab-scale systems modelling the spontaneous cocoa bean fermentation process are useful tools to research the influence of process parameters on the fermentation and the final bean quality. In this study in Honduras, a 1-kg lab-scale fermentation (LS-F) was compared to a 300-kg on-farm fermentation (OF-F) in a multiphasic approach, analysing microbial counts, microbial species diversity, physico-chemical parameters, and final dried bean quality. Yeast and total aerobic counts of up to 8 log CFU/g during the LS-F were comparable to the OF-F, while counts for lactic acid bacteria and acetic acid bacteria were up to 3 log CFU/g lower during the LS-F than during the OF-F. While species of the genera Hansenia, Saccharomyces, and Acetobacter dominated most of the fermentation processes, the genera dominating the drying phases were Pichia, Trichosporon, Pediococcus, and Acetobacter. Dried beans resulting from the LS-F, compared to the OF-F, were similar in contents of acetic acid, 6 times lower in lactic acid, up to 4 times higher in residual sugars, and 3-12 times higher in polyphenols. Dried beans processed at LS showed a similar flavour profile in terms of astringency, bitterness, acidity, and brown, fine, and cocoa flavours, but 2 units higher off-flavours than OF processed beans. With 81%, the share of well-fermented beans from the LS-F complied with industrial standards, whereas 7% over-fermented beans were above the threshold. Conclusively, the 5-day model fermentation and subsequent drying successfully mimicked the on-farm process, providing a high-throughput method to screen microbial strains to be used as starter cultures.

    The expansion and intensification of soya bean agriculture in southeastern Amazonia can alter watershed hydrology and biogeochemistry by changing the land cover, water balance and nutrient inputs. Several new insights on the responses of watershed hydrology and biogeochemistry to deforestation in Mato Grosso have emerged from recent intensive field campaigns in this region. Because of reduced evapotranspiration, total water export increases threefold to fourfold in soya bean watersheds compared with forest. However, the deep and highly permeable soils on the broad plateaus on which much of the soya bean cultivation has expanded buffer small soya bean watersheds against increased stormflows. Concentrations of nitrate and phosphate do not differ between forest or soya bean watersheds because fixation of phosphorus fertilizer by iron and aluminium oxides and anion exchange of nitrate in deep soils restrict nutrient movement. Despite resistance to biogeochemical change, streams in soya bean watersheds have higher temperatures caused by impoundments and reduction of bordering riparian forest. In larger rivers, increased water flow, current velocities and sediment flux following deforestation can reshape stream morphology, suggesting that cumulative impacts of deforestation in small watersheds will occur at larger scales.

    Full Text Available Faba beans (Vicia faba L. are an excellent protein source and should be more present in human diet, but due to their long cooking time, they are rarely used. So, in order to increase the accessibility of faba beans (Vicia faba L., experiments were carried out to obtain new food products. Extrusion-cooking was chosen as the potential thermal cooking process and two different products were obtained. One was made exclusively from faba bean (Vicia faba L. flour, while the second one was produced with a 50% addition of wheat flour to bean flour. Protein content, size, volume mass, pH and starch content for obtained products were analysed in order to characterise the products, as well as to see the differences from non-extruded faba beans (Vicia faba L. and obtained samples. The experiments were carried out using faba beans (Vicia faba L. obtained at Ltd. “Pure Horticultural Research Centre”. They were milled at Ltd. “Grauda spēks” and extruded with a twin screw extruder at Ltd. “Milzu”. The experiments showed that the extrusion process had decreased the protein content by 9%, but the starch content had risen by 13% with the addition of wheat flour. But, for sample, without added wheat flour differences were not significant. No significant size differences were observed in the obtained samples and pH values had no significant differences between extruded samples.

    In May 2003, the World Health Organization received reports about a possible outbreak of a hemorrhagic disease of unknown cause in the Imatong Mountains of southern Sudan. Laboratory investigations were conducted on 28 serum samples collected from patients in the Imatong region. Serum samples from 13 patients were positive for immunoglobulin M antibody to flavivirus, and serum samples from 5 patients were positive by reverse transcription–polymerase chain reaction with both the genus Flavivirus–reactive primers and yellow fever virus–specific primers. Nucleotide sequencing of the amplicons obtained with the genus Flavivirus oligonucleotide primers confirmed yellow fever virus as the etiologic agent. Isolation attempts in newborn mice and Vero cells from the samples yielded virus isolates from five patients. Rapid and accurate laboratory diagnosis enabled an interagency emergency task force to initiate a targeted vaccination campaign to control the outbreak. PMID:15207058

  17. Assessing the freshwater distribution of yellow eel

    Full Text Available In the global context of the decline in wild species, modeling the distribution of populations is a crucial aspect of ecological management. This can be a major challenge, especially for species, such as the European eel, that have complex life cycles, exhibit cryptic behavior, or migrate over long distances. A review of the literature suggests that eel size data could be used to assess and analyze freshwater distribution of eel. We argue that analyses based on small yellow eels (≤ 300 mm along the longitudinal course of rivers could provide a valuable tool for population monitoring. We propose a standardized catchment recruitment index and a colonization index based on the probability of occurrence (presence/absence data using logistic models for different size classes. The model developed here provides a convenient guide for assessing yellow eel stages in freshwater areas, and should have concrete applications for management of the species.

  18. Biological nitrogen fixation in common bean and faba bean using N-15 methodology and two reference crops

    1989-01-01

    A field was conducted on a Typic ustropepts soil located at 'La Tola', the experimental campus of the Agricultural Sciences Faculty at Tumbaco, Ecuador. The objectives were to quantify faba bean (Vicia faba) and common bean (Phaseolus vulgaris) biological nitrogen fixation, using quinoa (chenopodium quinoa) and maize (Zea mays) as reference crops. The average values were 80 and 70 per cent for faba bean and 42 and 14 per cent for common bean, respectively. It was assumed that nitrogen use eficiency was the same for fixing crops but observed that a crop with high nitrogen use efficiency overestimates legume biological nitrogen fixation. Results suggests that greater caution is needed when selecting reference crops for legumes with nitrogen fixation
