Introduction:?Actinomycosis is a rare granulomatous and supprative infection caused by Actinomyces, characterized by formation of sulfur granules. Actinomycosis of the pelvis commonly occurs in association with intrauterine device (IUD) especially in women. We present a rare case of patient with pelvic actinomycosis caused by foreign body, which was spread to intraabdomen. Case:?A 79-year-old woman, presenting with abdominal pain and chilling, was referred to our hospital. A computed tomography (CT) of the abdomen-pelvis showed ill-defined enhancing mass like lesion with extension into left upper abdominal wall and quadrangle shaped material in the upper vagina. (Figure A,B) It was verified that the foreign body removed by hysteroscopy guidance (Figure C) was the lid of cosmetics. We took a punch biopsy of cervix. Also we perfomed ultrasonogram guided percutaneous biopy for intraabdominal lesion. Histopathologic findings were actinomycosis in both sites. (Figure D,E) Intravenous amoxicillin was administered. After 4 weeks, antibiotics was switched to oral amoxicillin daily. 6 month later, follow up CT scan revealed complete clearing (Figure F) and antibiotic treatment was terminated.?Conclusions:?To the best of our knowledge, this is the first case report of actinomycosis of intraabdominal and pelvic actinomycosis caused by non medical foreign body in Korea. In a patient with actinomycosis, the possibility of infection related unintended foreign body should be considered and careful physical examination is needed to find out cause.
The continuous cooling transformation diagram of a high strength low alloyed steel was determined by adilatometer and microscopic analysis (OM, SEM) as well as thermodynamic analysis. As expected, Widmanstättenferrite, bainite and martensite coexisted for most cooling rates, which made it difficult to determinethe transformation kinetics of individual phases. However, peaks were clearly observed in the dilatometriccurves. By overlapping the curves, which were determined using various cooling rates, peakswere separated and the peak rate temperatures, as well as the temperature at the start of transformation (5%) andthe end of transformation (95%) of an individual phase, were determined. A SEM analysis was also conducted toidentify which phase existed and to quantify the volume fraction of each phase. It was confirmed that theadditional curve analysis described the transformation behavior more precisely than the conventionalcontinuous cooling transformation diagram, as determined by the volume measured from the microstructureanalysis.
Currently, frame memory compression (FMC) is widely adopted in video codecs. To store high-resolution video frames in external memory, the bus access time and the memory space are significant overheads for real-time video processing. There are many previous works which focus on data compression rates. However, in an actual system, several modules, including the video codec and the external memory, are connected via a system bus. In this environment, the gain in compression and the gain in transfer are very different. For a practical FMC design, not only the compression rate but also the transfer efficiency should be carefully considered. In this paper, a bus-aware interface design for one dimensional (1D) lossless FMC is proposed to reduce the amount of bus transfers. The proposed bitstream merging and tailed burst length schemes increase the transfer gain such that it is close to the gain in compression. The proposed 1D lossless FMC schemes are implemented in Verilog language and verified in an environment containing a high efficiency video coding (HEVC) encoder and a system bus.
Spontaneous coronary artery dissection is a rare cause of acute coronary syn-drome and sudden cardiac death. The incidence, causes, pathogenesis, and treat-ment have not been defined clearly, but spontaneous coronary artery dissection should be considered in young patients without major cardiovascular risk factors or in patients in the peripartum period who present with acute coronary syn-drome. The treatment is often challenging. Medical treatment is usually consid-ered, and percutaneous coronary intervention or coronary artery bypass surgery may be possible in some patients. We herein report two cases of middle-aged males with myocardial infarction who were treated with percutaneous coronary angioplasty.

We previously reported the potential of Senna tora L. seeds fermented by Lactobacillus casei (FSL) as a laxative agent in a loperamide-induced constipation rat model. Here, we examine the mechanism of action of FSL and its bioactive compound, revealed herein, on loperamide-induced constipation Sprague Dawley rat model. We identified the compound aurantio-obtusin (AO) using HPLC quantitative analysis. Rats were randomly assigned to six experimental groups (eight rats each)-normal and constipated groups (loperamide, FSL [100, 300, 500 mg/kg], and AO [1 mg/kg]). The FSL and AO-treated group showed an increase in the frequency, amount, and water content of feces in the constipated rat. Moreover, FSL and AO increased the intestinal transit speed in the constipated rat. Histological analysis revealed that FSL and AO recovered the intestinal mucus, the number of goblet cells, as well as thickness of the mucosa layer and muscle. Furthermore, the protein levels of the muscarinic acetylcholine receptor M3, which is involved in intestine contraction, were recovered in the FSL and AO-treated group. Its downstream signaling pathway (p-protein kinase C) was recovered by FSL and AO treatment. In conclusion, fermentation of S. tora L. seeds increases AO, which improves intestinal function, indicating that FSL is effective for treating constipation.
