Multiple Retroperitoneal Schwannomas Mimicking Adrenal Tumors

Schwannomas are benign tumors mostly arising from the head and neck. Retroperitoneal schwannomas are rare. Here we report the case of a 68-year-old woman with multiple retroperitoneal schwannomas. An abdominal computed tomography (CT) scan showed 1 non-enhancing mass with a low-density area, 4.6 cm in diameter, in the left adrenal region and another non-enhancing mass with a low-density area, 2.9 cm in diameter, in the para-aortic region. The patient had regularly undergone CT scans for malignant tumor screening in maintenance dialysis patients. Retrospectively, the 2 tumors had existed in the same regions in previous CT scans and had gradually increased in size. The tumors were completely resected. Pathological diagnosis of both tumors was schwannoma. When a CT scan shows a slowly growing retroperitoneal tumor with a low-density area, schwannoma should be considered. If the tumor increases in size, complete resection should be performed for pathological diagnosis

El proceso de venta y la decisión de compra del segmento masculino de 20 a 30 años, NSE C, de la empresa Topitop, Huaral – 2016

Es importante mencionar que, en la actualidad, toda empresa necesita tener bien estructurado su proceso de venta, ya que este es un pilar fundamental en toda la organización. Todos los procesos, dentro de la organización, son importantes, pero se debe de entender que sin ventas no hay ingresos, ni utilidades y por ende, la empresa no facturaría y esto puede conllevar a que la empresa fracase en un mercado tan competitivo. El objetivo de la presente investigación es determinar la relación entre el Proceso de Venta y la Decisión de compra, del segmento masculino de la empresa Topitop, Huaral - 2016. Como ya se mencionó, la presente investigación permite demostrar la importancia del Proceso de Venta y su relación con la Decisión de Compra, para ello se trabajó sobre una población de 3472 personas (solo hombres) de 20 a 30 años del NSE C, del distrito de Huaral, de la cual se obtuvo una muestra de 99 personas. La investigación posee un enfoque cuantitativo, de tipo aplicada, con un método hipotético deductivo y con un diseño descriptivo correlacional. Los resultados obtenidos a partir del cuestionario, demuestran que la variable Proceso de Venta, se relaciona con la variable Decisión de Compra

Post-traumatic diaphragmatic herniation of the liver, examined by positron emission tomography: case report

We present a case of post-traumatic diaphragmatic herniation of the liver, which mimicked an intrathoracic tumor. After an automobile accident, the patient underwent thoracotomies for hemothorax and lung cancer in the right chest. Seven months later, computed tomography (CT) demonstrated a round tumor in the thorax adjacent to the right diaphragm with a higher density than the liver parenchyma. An intrathoracic tumor including a primary or metastatic lung cancer was suspected. However, positron emission tomography (PET) showed that the uptake of fluorine-18-fluorodeoxyglucose (FDG) was identical to that in the liver, and the tumor appeared to be contiguous with the liver. Thus, we suspected liver herniation. Core needle biopsy revealed liver cells without neoplastic tissue. Upon surgical exploration, herniation of the liver was found and repaired. PET was helpful in providing morphological and functional information leading to accurate diagnosis of liver herniation in this unusual case

The impact of soil microbiome diversity on rhizosphere microbial communities'assembly and plant health.

The rhizosphere microbiome plays a significant role in the host plant?s health, such as defense against soil-borne diseases. However, the understanding of how the rhizosphere soil microbiome diversity impacts plant protection in production systems is still limited. This study aims to evaluate the impact of rhizosphere microbiome diversity in wheat plants inoculated with the soil-borne pathogen Bipolaris sorokiniana, with/without the antagonist Pseudomonas sp. CMAA1741, under a gradient of soil microbiome diversity. We hypothesized that the diversity and functionality of the rhizosphere determine the success of the antagonist bacterium establishment in the rhizosphere. Thus, a bioassay was conducted using natural soil, autoclaved soil, and three different dilutions of natural soil on autoclaved soil. The results showed that antagonist inoculated treatments resulted in higher plant height and root dry mass, while, in soils with low diversity, the severity disease index and the biocontrol effect of the antagonist were higher across all treatments that received the fungal pathogen with/without inoculant, respectively. Sterilized soils inoculated with both agents had the most effectiveness in pathogen biocontrol, with enrichment of Chtoniobacter and Chitinophaga bacterial genera in this treatment. Also, an increase of Chitinophaga bacterial genus and Alternaria, Chaetomium, and Waitea fungal genera were observed when just pathogen was inoculated in soils

Radiotherapy for mucosa-associated lymphoid tissue lymphoma of the ocular adnexa

Objectives: We investigated the results of radiotherapy for mucosa-associated lymphoid tissue (MALT) lymphoma of the ocular adnexa. Methods: Twenty-one patients with MALT lymphoma of the ocular adnexa were treated with radiotherapy alone at a dose ranging from 30 to 54Gy. The disease arose from the conjunctiva in 15 patients (9 with bilateral involvement), and from the retrobulbar space in 6 patients (1 with bilateral involvement). Results: All patients with MALT lymphoma achieved a CR or unconfirmed CR (CRu). The 5-and 10-year overall survival rates of all patients with MALT lymphoma were 100% and 90%, respectively. The 5-and 10-year cause-specific survival rates were 100% and 100%, respectively. In all patients with delayed toxicity, the radiation dose was more than 40Gy. Conclusions: Excellent local control and survival can be achieved for patients with MALT lymphoma of the ocular adnexa using radiotherapy alone

社会人バスケットボールチームにおけるチームサティスファクションの構成要因

The purpose of this study was to investigate composition factor of "Team Satisfaction" on basketball club team members and to suggest the way of improving "Team Satisfaction". The subjects were 144 participant belonging to various basketball club teams. The results were summarized as fellows: 1) Basketball club team members were satisfied with various things of their activities. 2) Five factors were extracted as the determinant factors of "Team Satisfaction". These were "Communication and Mood", "Practicing and Leader", "Motivation of upskilling", "Self-efficacy" and "Winning desire". 3) One factor was contribute to "Team Satisfaction". This was "Communication and Mood". These results suggest that the most important thing to improve "Team Satisfaction" is making a good relationship among team-mates

Features of Phyllodes Tumours and Fibroadenomas Differ on MR Images

This retrospective study aimed to determine how the magnetic resonance imaging (MRI) and histopathological findings of phyllodes tumours (PT) and fibroadenomas (FA) correlate and verify whether they are useful for preoperative diagnosis. We retrospectively reviewed 12 PT and 43 FA that were surgically resected after MRI assessment between 2009 and 2015. The shape and signal intensity (SI) of the tumours on T2-weighted images (T2WI), the apparent diffusion coefficient, and SI were dynamically assessed. High SI areas suggestive of haemorrhage were significantly more frequent on pre-contrast T1WI of PT than that of FA (66.7% vs. 16.2%, p = 0.00034). The results of the SI analysis showed a higher intratumoural SI for PT than FA on T2WI (7.07 vs. 4.37, p = 0.0022). Overall enhancement was more intense among PT than FA, while SI was significantly higher at 100 seconds (2.03 vs. 1.60, p = 0.043) when enhanced effects on pre-enhanced tumours were quantified based on SI ratios. Not only can MRI morphologically differentiate PT from FA, it can also provide information about tissue composition and vascularization, the quantitation of which seems useful for differentiation

高等学校のクラブ活動における指導者の暴力行為

This study seeks to illuminate the state of leadership violence in high school sports clubs and the athlete perceptions of such violence. A total of 226 female college students who engaged in sports club activities in high school responded to our survey. The study found the following： （1） 28.8% of the respondents experienced leadership violence. Many of those who experienced violence belonged to ball game clubs. （2） The competence of athletes who experienced violence was higher than those who did not experience violence. （3） The frequency of violence was higher for athletes who had more opportunities to compete in games. （4） Much of the violence took the form of slapping. One of the most commonly cited reasons was not reaching expectations. （5） Athletes had a tendency to think that although leadership violence was frustrating，it could not be helped because such violence was a result of their own failures. Accordingly，participants tended to be grateful toward leaders for inflicting violence because they felt that such actions helped them grow both mentally and technically. （6） While many athletes who experienced violence believed it to be necessary at times，those who did not experience violence believed it to be is unnecessary. （7） It is highly likely that many of the survey respondents，regardless of their experience with leader violence，will inflict violence on their future student athletes if the students do not comply with rules

Multi-Analytical Interactions in Support of Sugarcane Agroecosystems Sustainability in Tropical Soils

The risks of sugarcane management on soil microbes and their relationships with soil physicochemical factors and biogeochemical processes have not been described from an integrated perspective for different agronomic practices. Here, we provide a platform for multi-analytical interactions between ecologists analyzing the soil microbes at multiple ecological levels and geoscientists measuring the release of greenhouse gases and the physicochemical soil factors including labile fractions from soil organic matter in tropical sugarcane management systems. We compile the benefits and risks of nutrient management and soil amendments as well as of crop residue and harvest management in sugarcane soils on belowground microbial life and biogeochemical processes mediated by soil microbial communities, and we demonstrate that the massive planting of the crop brings environmental risks that include a potential impact on tropical soil ecosystem sustainability. We emphasize that soil management and harvest management are critical for supporting the sustainable development of biofuel production in tropical areas
