Copper-based antimicrobial compounds are widely used to control plant bacterial pathogens. Pathogens have adapted in response to this selective pressure. Xanthomonas citri pv. citri, a major citrus pathogen causing Asiatic citrus canker, was first reported to carry plasmid-encoded copper resistance in Argentina. This phenotype was conferred by the copLAB gene system. The emergence of resistant strains has since been reported in Réunion and Martinique. Using microsatellite-based genotyping and copLAB PCR, we demonstrated that the genetic structure of the copper-resistant strains from these three regions was made up of two distant clusters and varied for the detection of copLAB amplicons...

Never in mitosis gene A (NIMA)-related kinase 2 (NEK2) is a microtubule-associated protein that regulates spindle assembly in human cells and is overexpressed in various malignancies. However, the role of NEK2 in hepatocellular carcinoma (HCC) remains undetermined. We performed RNA-seq of the HCC cell line SMMC-7721 and the normal liver cell line HL-7702 using the Ion Proton System. NEK2 expression was detected using quantitative reverse transcription polymerase chain reaction in two cell lines and 5 matched HCC and adjacent non-tumorous liver tissues...

RESULTS OF THE SCREENING OF THYROIDS: Because of the March 2011 nuclear accident in Fukushima, Japan, the Fukushima Prefecture initiated a thyroid ultrasound examination program. The first cycle of examinations on all children (more than 300,000) of the Fukushima Prefecture identified 116 patients as having malignant or suspected malignant thyroid nodules, and in the second cycle 59 new cases were identified. According to the available data, the thyroid cancers found by the screening are unlikely to be due to radiation, but the possibility cannot be excluded...

Malignant proliferating trichilemmal tumour (MPTT) is a rare cutaneous tumour predominantly affecting the scalp, eyelids, neck and face of elderly women. It is a large, solitary, multilobulated lesion that may arise within a pilar cyst. These tumours are largely benign, often cystic and are characterized by trichilemmal keratinisation. However at times, the tumour has an aggressive clinical course and a propensity for distant metastasis. We report a case of a 29-year-old male who presented with a scalp swelling...

The taxonomic description of a nitrogen fixing actinobacterium, strain BMG5.1T, as a new species within the genus Frankia was based on a polyphasic approach. The strain was isolated from the root nodules of Coriaria japonica, and it fulfilled Koch's postulates by inducing effective nodules on Coriaria spp. and Datisca spp. Based on phenotypic and chemotaxonomic features, strain BMG5.1T is distinguishable from all other Frankia species. It is characterised by the presence of PI, DPG, PG and GPL in its polar lipids and galactose, glucose, mannose and a trace of ribose as cellular sugars...

Rhizobia-legume symbiosis is the most well researched biological nitrogen fixation system. Coating legume seeds with rhizobia is now a recognized practical measure for improving the production of legume corp. However, the efficacy of some commercial rhizobia inoculants cannot be guaranteed in China due to the low rate of live rhizobia in these products. A greenhouse experiment was conducted to assess the effects of different rhizobial inoculant formulations on alfalfa productivity and nitrogen fixation. Two rhizobia strains, (ACCC17631 and ACCC17676), that are effective partners with alfalfa variety Zhongmu No...

Accurate characterization of cirrhotic nodules and early diagnosis of hepatocellular carcinoma (HCC) are of vital importance. Currently, computed tomography (CT) and magnetic resonance (MR) imaging are standard modalities for the investigation of new nodules found at surveillance ultrasonography (US). This article describes the successful integration of contrast material-enhanced US into a multimodality approach for diagnosis of HCC and its benefits in this population. The application of contrast-enhanced US immediately following surveillance US allows for prompt dynamic contrast-enhanced evaluation, removing the need for further imaging of benign lesions...

Inflammatory and subcutaneous nodules can arise in treated and untreated cases of Whipple disease (WD). The inflammatory immune reconstitution syndrome describes paradoxical clinical inflammatory worsening of a preexisting condition because of a return of immune function. Clinicopathologic examination of 4 patients with WD who presented with erythema nodosum leprosum (ENL)-like lesions and the findings of a systematic review of this phenomenon revealed that ENL-like lesions occurred in predominantly middle-aged male patients who suffered from WD, mostly on the legs...

Juvenile xanthogranuloma is a bening pathology and it represents the most common form of non-Langerhans cell histiocytosis. It is characterized by the presence of papules or firm nodules of a pinkish or yellow-brownish nature, which mainly compromise the skin and, exceptionally, other organs. It is a self-limited entity having a spontaneous regression during the first five years of life. We report the case of a one-month-old patient who presented a congenital tumor in the abdomen, whose histopathology showed the presence of multinucleated giant Touton cells, which are typical of this pathology...
