ABSTRACT The original two-order separating sieve has a good potato-soil separating ability, but it causes significant damage to potatoes while ensuring a high potato detection rate, which in turn affects the working effectiveness of the potato digger. Thus, it is necessary to improve the design of the original swing separation sieve with a two-order sieve surface to one with a three-order sieve surface to solve the contradiction between the potato detection and potato damage. On this basis, the movement characteristics of potatoes and the separation performance of the new sieve were experimentally investigated. The experiment was conducted in a test field in Wuchuan County using a completely randomized design in a single-factor scheme with three factors and five levels, with five crank speeds (140, 150, 180, 210 and 225 rpm), five machine forward speeds (1.41, 1.51, 1.70, 1.89 and 2.21 km h-1) and five boom-connecting rod length combinations (250-350-1,030, 250-370-1,040, 270-370-1,050, 290-370-1,060 and 310-370-1,070 mm). Each experiment was repeated three times at each level, and the average value was taken as the final result. The experimental results demonstrate that the new three-order separation sieve can ensure a high potato detection rate while maintaining a low potato skin breakage rate. twoorder two order potatosoil soil ability digger Thus threeorder basis investigated singlefactor single factor levels 140, 140 (140 150 180 21 22 rpm, rpm , rpm) 1.41, 141 1 41 (1.41 151 51 1.51 170 70 1.70 189 89 1.8 221 2 2.2 h1 h h-1 boomconnecting boom connecting 2503501,030, 2503501030 250 350 1,030, 030 (250-350-1,030 2503701,040, 2503701040 370 1,040, 040 250-370-1,040 2703701,050, 2703701050 270 1,050, 050 270-370-1,050 2903701,060 2903701060 290 1,060 060 290-370-1,06 3103701,070 3103701070 310 1,070 070 310-370-1,07 mm. mm . mm) level result 14 (14 15 18 1.41 4 (1.4 5 1.5 17 7 1.7 8 1. 2. h- 2503501 2503501,030 250350103 25 35 1030 1,030 03 (250-350-1,03 2503701 2503701,040 250370104 37 1040 1,040 04 250-370-1,04 2703701 2703701,050 270370105 27 1050 1,050 05 270-370-1,05 2903701 2903701,06 290370106 29 1060 1,06 06 290-370-1,0 3103701 3103701,07 310370107 31 1070 1,07 07 310-370-1,0 (1 1.4 (1. 250350 2503501,03 25035010 3 103 1,03 0 (250-350-1,0 250370 2503701,04 25037010 104 1,04 250-370-1,0 270370 2703701,05 27037010 105 1,05 270-370-1,0 290370 2903701,0 29037010 106 1,0 290-370-1, 310370 3103701,0 31037010 107 310-370-1, ( 25035 2503501,0 10 (250-350-1, 25037 2503701,0 250-370-1, 27037 2703701,0 270-370-1, 29037 2903701, 1, 290-370-1 31037 3103701, 310-370-1 2503 2503501, (250-350-1 2503701, 250-370-1 2703 2703701, 270-370-1 2903 290-370- 3103 310-370- (250-350- 250-370- 270-370- 290-370 310-370 (250-350 250-370 270-370 290-37 310-37 (250-35 250-37 270-37 290-3 310-3 (250-3 250-3 270-3 290- 310- (250- 250- 270- (250 (25 (2

RESUMO A peneira de separação de duas ordens original tem uma boa capacidade de separação batata-solo, mas causa danos significativos às batatas ao mesmo tempo em que garante uma alta taxa de evidência de batatas, o que, por sua vez, afeta a eficácia do trabalho da escavadeira de batatas. Assim, o estudo teve como objetivo aprimorar a peneira de separação de balanço original com uma superfície de peneira de duas ordens para uma nova peneira de separação com uma superfície de peneira de três ordens para resolver a contradição entre a taxa obvia de batatas e os danos às batatas na operação da peneira original. Com base nisso, as características de movimentação das batatas e o desempenho de separação da nova peneira foram investigados experimentalmente no campo. O experimento foi conduzido em um campo de teste no Condado de Wuchuan, utilizando um delineamento completamente aleatório em um esquema de fator único com três fatores e cinco níveis, com cinco velocidades de manivela (140, 150, 180, 210 e 225 rpm), cinco velocidades de avanço da máquina (1,41, 1,51, 1,70, 1,89 e 2,21 km h-1) e cinco combinações de comprimento da haste de ligação do braço (250-350-1.030, 250-370-1.040, 270-370-1.050, 290-370-1.060 e 310-370-1.070 mm). Cada experimento foi repetido três vezes em cada nível, e o valor médio foi considerado como o resultado final. Os resultados experimentais demonstram que a nova peneira de separação de três ordens pode garantir uma alta taxa de detecção de batatas enquanto mantém uma baixa taxa de danos à casca das batatas. batatasolo, batatasolo batata solo, solo batata-solo vez Assim nisso Wuchuan níveis 140, 140 (140 150 180 21 22 rpm, rpm , rpm) 1,41, 141 1 41 (1,41 151 51 1,51 170 70 1,70 189 89 1,8 221 2 2,2 h1 h h-1 2503501.030, 2503501030 250 350 1.030, 030 (250-350-1.030 2503701.040, 2503701040 370 1.040, 040 250-370-1.040 2703701.050, 2703701050 270 1.050, 050 270-370-1.050 2903701.060 2903701060 290 1.060 060 290-370-1.06 3103701.070 3103701070 310 1.070 070 310-370-1.07 mm. mm . mm) nível final 14 (14 15 18 1,41 4 (1,4 5 1,5 17 7 1,7 8 1, 2, h- 2503501 2503501.030 250350103 25 35 1030 1.030 03 (250-350-1.03 2503701 2503701.040 250370104 37 1040 1.040 04 250-370-1.04 2703701 2703701.050 270370105 27 1050 1.050 05 270-370-1.05 2903701 2903701.06 290370106 29 1060 1.06 06 290-370-1.0 3103701 3103701.07 310370107 31 1070 1.07 07 310-370-1.0 (1 1,4 (1, 250350 2503501.03 25035010 3 103 1.03 0 (250-350-1.0 250370 2503701.04 25037010 104 1.04 250-370-1.0 270370 2703701.05 27037010 105 1.05 270-370-1.0 290370 2903701.0 29037010 106 1.0 290-370-1. 310370 3103701.0 31037010 107 310-370-1.

Abstract Soluble dietary fiber has attracted much attention due to its significant health benefits to consumers. Edible fungi are abundant sources of soluble dietary fiber (SDF). The content and composition of soluble dietary fiber in edible fungi variy greatly according to varieties, growth stages and different parts. This review focuses on the extraction methods of soluble dietary fiber from edible fungi, such as Lentinula edodes, Agrocybe cylindracea. The possible health benefits of mushroom soluble dietary fiber in relationship with hypoglycemic effect, regulatory mechanism of pancreatic lipase, gut microbiota and macrophages are also discussed. Finally, the application and development potential of mushroom soluble dietary fiber are pointed out.

Abstract Polysaccharides and anthocyanins are one of the main components of many foods, and their interaction affects the texture and nutrition of foods. The anthocyanin-polysaccharide complex was prepared from anthocyanin of plum (Prunus salicina Lindl. cv. Furong) and polysaccharide of Tremella fuciformis. The structure changes of anthocyanin and polysaccharide before and after interaction were investigated by UV-visible spectroscopy, infrared spectroscopy and scanning electron microscopy. The absorption peak at 510 nm of anthocyanin-polysaccharide complex weakened at pH 5.0, and the intensity of absorption spectrum increased with the concentration of polysaccharide. The absorption peaks of anthocyanin-polysaccharide complexes were shifted in the infrared spectral curve of anthocyanin, and the formation of complex was caused by electrostatic interaction and hydrogen bond interaction between anthocyanin and polysaccharide. From microstructural analysis, anthocyanin and polysaccharide were effectively bound together. This can provide theoretical guidance for the structural design of anthocyanin-polysaccharide food and the development and utilization of new food ingredients.

Herein, the synthesis, characterization and catalytic application of an organic-inorganic, palladium (Pd)-containing hybrid material, poly(amidoamine)-cyclodextrin (Pd@PAAs-CD), is reported as an efficient catalyst for Suzuki-Miyaura coupling reactions. The structure of Pd@PAAs-CD was confirmed by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), inductively-coupled plasma atomic emission spectroscopy (ICP-AES), and 1H nuclear magnetic resonance (NMR) spectroscopy. Furthermore, an efficient protocol has been developed using Pd@PAAs-CD as the catalyst in a Suzuki-Miyaura cross-coupling reaction in an aqueous medium in high yields. By using cyclodextrin (CD) as the mediator grafted onto PAAs, the Pd nanoparticles (NPs) were dispersed and enhanced the catalytic reaction by promoting host-guest interactions with the CD. In addition, the reusability of the Pd@PAAs-CD hybrid material is demonstrated for use in multiple sequential cross-coupling reactions.

RESUMO OBJETIVO: Descrever o caso de uma paciente diabética que desenvolveu osteomielite vertebral e abcesso bilateral do psoas com formação de gás causada por klebsiella pneumoniae. MÉTODOS: Uma mulher de 64 anos de idade, com 4 anos de histórico de diabetes mellitus tipo 2, foi admitida no Serviço de Emergência. A paciente apresentava um quadro de dias de febre alta acompanhada de calafrios e um histórico de 5 horas de consciência. Ela recebeu tratamento empírico com antitérmico, após o qual a febre diminuiu. RESULTADOS: A febre retornou após um intervalo de três horas. Uma tomografia computadorizada do abdome revelou osteomielite vertebral e abcesso bilateral do músculo psoas com formação de gás. A cultura do sangue e o fluido purulento revelaram o crescimento de Klebsiella pneumoniae. A paciente recebeu antibióticos e terapia de drenagem bilateral após o cateter de drenagem ser posicionado na cavidade do abscesso com auxílio de TC. Devido a sérios danos à coluna vertebral e a dor permanente, a paciente foi submetida à fixação vertebral interna minimamente invasiva e recuperou-se com sucesso. CONCLUSÃO: Um caso de osteomielite vertebral e abscesso do psoas bilateral com a formação de gás causada por Klebsiella pneumoniae em uma paciente diabética. Antibioticoterapia, drenagem e fixação vertebral interna minimamente invasiva foram realizadas, o que permitiu um bom resultado.

SUMMARY OBJECTIVE: We describe the case of a diabetic patient who developed vertebral osteomyelitis and bilateral psoas abscess with gas formation due to klebsiella pneumoniae. METHODS: A 64-year-old woman with a 4-year history of type-2 diabetes mellitus was admitted to the Emergency Department. The subject had a 2-day history of high-grade fever associated with chills and a 5-hour history of consciousness. She received empirical treatment with febrifuge, after which her fever decreased. RESULTS: Her fever recurred after an interval of three hours. A computed tomography scan of the abdomen revealed vertebral osteomyelitis and bilateral psoas muscle abscess with gas formation. Blood culture and purulent fluid described the growth of the Klebsiella pneumoniae. The patient received antibiotic therapy and bilateral drainage therapy after the drainage catheter was placed into the abscess cavity by CT-guidance. Due to the serious damage to the vertebral column and permanent pain, the patient underwent minimally invasive internal spinal fixation and recovered successfully. CONCLUSION: A case of vertebral osteomyelitis and bilateral psoas abscess with gas formation caused by Klebsiella pneumoniae in a diabetic patient. Antibiotic therapy, drainage, and minimally invasive internal spinal fixation were performed, which enabled a good outcome.

Abstract: We report a case of amelanotic acral melanoma in a 42-year-old Chinese woman. Ten months previously the patient found a 2-cm asymmetric erythematous macular plaque on her left sole. The lesion was diagnosed as verruca plantaris by every physician the patient consulted. One month ago, an enlarged lymph node was detected in the left groin, which biopsy reported as metastatic melanoma. Dermoscopy suggested verruca plantaris, and positron emission tomography (PET) revealed increased glucose metabolism in the macular plaque. Finally, biopsy of the plaque revealed amelanotic melanoma. Misdiagnosis and diagnostic delay are usually associated with poorer patient outcomes. Awareness of atypical presentations of acral melanoma is thus important for decreasing misdiagnosis rates and improving patient outcomes.

OBJECTIVES: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS: The electronic medical records of 20 patients with septic pulmonary embolism who required intensive care unit admission between January 2005 and December 2013 were reviewed. RESULTS: Multiple organ dysfunction syndrome developed in 85% of the patients, and acute respiratory failure was the most common organ failure (75%). The most common computed tomographic findings included a feeding vessel sign (90%), peripheral nodules without cavities (80%) or with cavities (65%), and peripheral wedge-shaped opacities (75%). The most common primary source of infection was liver abscess (40%), followed by pneumonia (25%). The two most frequent causative pathogens were Klebsiella pneumoniae (50%) and Staphylococcus aureus (35%). Compared with survivors, nonsurvivors had significantly higher serum creatinine, arterial partial pressure of carbon dioxide, and Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores, and they were significantly more likely to have acute kidney injury, disseminated intravascular coagulation and lung abscesses. The in-hospital mortality rate was 30%. Pneumonia was the most common cause of death, followed by liver abscess. CONCLUSIONS: Patients with septic pulmonary embolism who require critical care, especially those with pneumonia and liver abscess, are associated with high mortality. Early diagnosis, appropriate antibiotic therapy, surgical intervention and respiratory support are essential.

OBJECTIVES: Septic pulmonary embolism caused by a Klebsiella (K.) pneumoniae liver abscess is rare but can cause considerable morbidity and mortality. However, clinical information regarding this condition is limited. This study was conducted to elucidate the full disease spectrum to improve its diagnosis and treatment. METHOD: We reviewed the clinical characteristics, imaging findings, and clinical courses of 14 patients diagnosed with septic pulmonary embolism caused by a K. pneumoniae liver abscess over a period of 9 years. RESULTS: The two most prevalent symptoms were fever and shortness of breath. Computed tomography findings included a feeding vessel sign (79%), nodules with or without cavities (79%), pleural effusions (71%), peripheral wedge-shaped opacities (64%), patchy ground-glass opacities (50%), air bronchograms within a nodule (36%), consolidations (21%), halo signs (14%), and lung abscesses (14%). Nine (64%) of the patients developed severe complications and required intensive care. According to follow-up chest radiography, the infiltrates and consolidations were resolved within two weeks, and the nodular opacities were resolved within one month. Two (14%) patients died of septic shock; one patient had metastatic meningitis, and the other had metastatic pericarditis. CONCLUSION: The clinical presentations ranged from insidious illness with fever and respiratory symptoms to respiratory failure and septic shock. A broad spectrum of imaging findings, ranging from nodules to multiple consolidations, was detected. Septic pulmonary embolism caused by a K. pneumoniae liver abscess combined with the metastatic infection of other vital organs confers a poor prognosis.
