The Role of Imaging in the Diagnosis of Recurrence of Primary Seminal Vesicle Adenocarcinoma

Primary seminal vesicle (SV) adenocarcinoma is a rare tumor. A small amount of data about the role of imaging to detect tumor recurrence is available. We report the case of a 58-year-old patient with primary SV clear-cell well-differentiated adenocarcinoma. Clinical and instrumental examinations were negative for the 32 months after treatments when computed tomography scan, [18F]fluoro-D-glucose positron emission tomography/computed tomography and pelvic magnetic resonance imaging showed the appearance of a lesion in the left perineal muscle suspected for recurrence. Patient was symptomless. Cytology of the suspected lesion confirmed SV adenocarcinoma recurrence. The combined approach, using radiological and nuclear medicine techniques, seems to be effective in the follow-up of SV adenocarcinoma. Technological advances, together with awareness of this rare tumor, have the potential of improving patients outcomes not only by providing earlier detection and accurate staging, but also by detecting recurrence and thereby avoiding delays and therapeutic dilemmas.
Ethylene from renewable ethanol: Process optimization and economic feasibility assessment
Martina Frosi,Antonio Tripodi,Francesco Conte,Gianguido Ramis,Nader Mahinpey,Ilenia Rossetti 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.104 No.-
At present, ethylene is the most widely produced organic compound in the chemical industry. The maincommercial way to obtain ethylene is by steam cracking of a wide range of hydrocarbon feedstocks, butbiomass-derived ethanol can be catalytically dehydrated as a sustainable alternative route in order toexploit new renewable sources. The aim of this work is to design an optimal bioethanol-tobioethyleneplant, with a capacity of 445,652 ton/year, and to assess its economic feasibility. This designfeatures an improved production capacity and intensified energy management. The main novelty of this study is the use of diluted bioethanol solutions, bypassing the energy intensiveand expensive dehydration step. Moreover, while the first industrial bioethanol-to-bioethylene processuses NaOH to purify the outcoming flow from CO2, this plant uses diluted Methyldiethanolamine(MDEA), regenerated in situ. With this plant, the double of the capacity of the Braskem’s plant, nowthe largest one, can be reached in an environmentally more sustainable manner. A pinch analysis was performed, in order to minimize the energy consumption of the process by optimizingthe heat recovery systems. The economic analysis of the process consists of the evaluation of thetotal cost of the plant (TOC) including the sum of the CAPital EXpenditures (CAPEX) and the OPeratingones (OPEX), together with some sensitive profitability indexes (net yearly profit, net present value,net rate of return and cash flow analysis). The designed process presents an economically competitivesolution compared to the current bioethylene production units. Assuming a premium price of between 0.293 $/kg for diluted bioethanol, the proposed plant is competitivewith the lowest production cost for bioethylene (Brazil and India), while a sensitivity analysis ondiluted bioethanol price evidenced that this option remains competitive still in Europe with a bioethanolcost 0.65 $/kg.

Purpose: This study aimed to quantify the influence of tooth position within the field-of-view (FOV) on cone-beam computed tomography (CBCT) imaging artifacts’ intensity when assessing teeth restored with various intracanal materials. Materials and Methods: Seventy single-rooted teeth were divided into 7 groups (10 teeth per group): NiCr post (NC), AgPd post (AP), metal core fiberglass post (MCFG), fiberglass post (FG), anatomical fiberglass post (AFG), fiberglass post cemented with core build-up cement (FGCo), and anatomical fiberglass post cemented with core build-up cement (AFGCo). All posts were cemented using a regular dual-curing resin cement (Allcem), except FGCo and AFGCo which were cemented with a core build-up dual-curing resin cement (AllcemCore). Each tooth was scanned on a CS9000 in 5 positions within the FOV: a central position, anterior horizontal peripheral, peripheral superior, peripheral inferior, and posterior horizontal peripheral position. Hyperdense, hypodense, remaining teeth areas and ROI areas were quantitatively analyzed using ImageJ software. Results: Posterior horizontal peripheral position increased the intensity of artifacts on FGCo and AFGCo post groups (P<0.05), and specifically the hypodense artifact intensity on FG and AFG post groups (P<0.05). NC and AP groups presented greater intensity of artifacts than any other post groups (P<0.05). Conclusion: Artifact intensity increases in the presence of high atomic number materials and when the object is not centered within the FOV. The impact of positioning within the FOV on artifact was greater for fiberglass posts cemented with core build-up dual-curing cement than for metal posts and fiberglass posts cemented with regular dual-curing cement.
The Link between Fusobacteria and Colon Cancer: a Fulminant Example and Review of the Evidence

Systemic infections due to Fusobacterium may originate in the tonsillar/internal jugular veins or from the abdomen. We encountered a patient who presented with bacteremia, fulminant septic shock, and extensive soft tissue pyogenic infection due to Fusobacterium necrophorum. In addition, there was widespread metastatic colon cancer with the unique finding of pre-mortem co-localization of F. necrophorum and cancer cells at a site distant from the colon. We reviewed the literature of the association of F. necrophorum and colon cancer, and discuss the evidence of how each of these 2 distinct entities may mutually augment the development or progression of the other.

This paper narrates the origin of the “Transmission of the Way” (dotong) in Korea and the emergence of scholarly lineages. It connects this with the particular socio-political constellation of Joseon society according to which social standing determined participation in the political world. For this reason, Korean dohak was always more political than in China. Following the death of Toegye Yi Hwang and Yulgok Yi I, the Way bifurcated, and its application to the intellectual discourse and political reality depended much on those in power. This was equally true for the selection of scholarly candidates for the honor of enshrinement in the Shrine of Confucius (Munmyo). What emerged as “orthodoxy” aroused dissent that was suppressed by the state. Toward the end of the dynasty, the scholarly atmosphere became more fluid, and personal interpretations of the Classics began to emerge.
