Impalement Injury of the Urinary Bladder: A Case Report
Jun Morita,Michio Naoe,Takehiko Nakasato,Yoshio Ogawa 대한비뇨의학회 2012 Investigative and Clinical Urology Vol.53 No.6
Impalement injury of the urinary bladder, especially secondary to rectal impalement, is extremely rare. In this case, a 31-year-old man sustained a steel pipe impalement injury through his perirectal region. He presented with gross hematuria, abdominal defense, and a penetrating wound. On the basis of the computed tomography findings and abdominal defense, we suspected a through-and-through bladder perforation from the rectal space to the intraperitoneum. Laparotomy revealed a through-and-through bladder perforation as well as damage to the right ureter, 3 distinct ileal injuries, and rectal anterior, anal, and right seminal vesicle injuries. Surgical repair of each damaged site was undertaken. The prompt diagnosis and surgical repair ensured good postoperative recovery.

In this study, we characterized the physical form of allergenic Cry j 1 in the urban atmosphere. Through an immunofluorescence antibody method, we showed that allergenic Cry j 1 exists as fine particles (‹1.1μm). To determine Cry j 1 concentrations and its particle size distribution, we used the ELISA method to confirm that most Cry j 1 exists as fine particles in the urban atmosphere and is found at high concentrations on fine day next to rainy day. Furthermore,we evaluated Cry j 1 denaturation by using the Biacore J system based on the surface plasmon resonence (SPR) principle and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). We showed that the dissociation constant (KD) of Cry j 1 that has been exposed to urban polluted air is lower (1.76×10-14 M) than that of Cry j 1 (1.32×10-9-3.37×10-9 M) of original pollen grains that has not been exposed to air pollutants. Cry j 1 turns into low molecular weight proteins by reacting with various acidic solutions. In sum, we showed that allergenic Cry j 1exists as fine particles that can deposit in the lower respiratory tract. This finding clarifies the relationship between Japanese cedar pollinosis and air pollutants.

This paper aimed to summarize the current situation of prognostication for patients with an expected survival of weeks or months, and to clarify future research priorities. Prognostic information is essential for patients, their families, and medical professionals to make endof- life decisions. The clinician’s prediction of survival is often used, but this may be inaccurate and optimistic. Many prognostic tools, such as the Palliative Performance Scale, Palliative Prognostic Index, Palliative Prognostic Score, and Prognosis in Palliative Care Study, have been developed and validated to reduce the inaccuracy of the clinician’s prediction of survival. To date, there is no consensus on the most appropriate method of comparing tools that use different formats to predict survival. Therefore, the feasibility of using prognostic scales in clinical practice and the information wanted by the end users can determine the appropriate prognostic tool to use. We propose four major themes for further prognostication research: (1) functional prognosis, (2) outcomes of prognostic communication, (3) artificial intelligence, and (4) education for clinicians.

<P><B>Highlights</B></P><P>► Japanese flounder type I IFN gene was cloned and clustered with Acanthopterygii. ► The poly I:C-responsible region (−634 to −179bp) was found in IFN promoter. ► Transcriptional activity of IFN promoter was enhanced by the flounder IRF3. ► The activity of IFN promoter was induced by RLRs after poly I:C-stimulation.</P> <P><B>Abstract</B></P><P>Type I interferon (IFN) induces the antiviral response in innate immunity. The type I IFN gene cloned from Japanese flounder (<I>Paralichthys olivaceus</I>) has a length of 1189bp and consisting of 5 exons and 4 introns. In a phylogenetic tree of type I IFNs, Japanese flounder grouped with other Acanthopterygii. To gain insight into the transcriptional regulation of IFN gene, the 1.36kb 5′-upstream region including numerous canonical motifs to bind transcription factors [for example, IFN regulatory factor (IRF)] was analyzed. In HINAE cells using a luciferase reporter assay, poly I:C-responsive transcriptional activity was found in the region from −634 to −179bp. This region includes several IRF motifs. In the presence of poly I:C, overexpression of IRF3 and RLR strongly enhanced transcriptional activity. These results suggest that the transcriptional regulation of Japanese flounder type I IFN is regulated by IRF3 after triggering with dsRNA sensors.</P>

<P>Pulse electrochemical nanopatterning, a non-contact scanning probe lithography process using ultrashort voltage pulses, is based primarily on an electrochemical machining process using localized electrochemical oxidation between a sharp tool tip and the sample surface. In this study, nanoscale oxide patterns were formed on silicon Si (100) wafer surfaces via electrochemical surface nanopatterning, by supplying external pulsed currents through non-contact atomic force microscopy. Nanoscale oxide width and height were controlled by modulating the applied pulse duration. Additionally, protruding nanoscale oxides were removed completely by simple chemical etching, showing a depressed pattern on the sample substrate surface. Nanoscale two-dimensional oxides, prepared by a localized electrochemical reaction, can be defined easily by controlling physical and electrical variables, before proceeding further to a layer-by-layer nanofabrication process.</P>

대두 및 고구마로부터 얻은 ${\beta}-Amylase$의 단백질 구조를 CD Spectra, 항체반응, 화학적 절단을 통하여 비교하였다. 고구마 ${\beta}-Amylase$는 4개의 동일한 subunit로 구성되어 있으며 대두 ${\beta}-Amylase$는 Subunit구조를 하고 있지 않았다. 또한 두 효소는 변성시킨 상태에서 SDS-gel전기영동, gel filtration한 결과 분자량은 동일하였다. 그리고 대두 및 고구마 ${\beta}-Amylase$는 CD spectra상 유사한 2차구조를 나타내고 있으나 방향족 측쇄가 상이함을 나타냈다. 한편 cyteine 잔기 및 methionine 잔기의 화학적 절단한 결과 두 효소는 동일한 아미노산 배일을 나타냈다. 또한 면역학적인 방법에 의해서도 두 효소는 유사성이 인정되었다. 한편 대두 ${\beta}-Amylase$에 대한 항체는 고구마 ${\beta}-Amylase$의 활성을 억제하였으나 밀, 보리, 무우 ${\beta}-Amylase$에 대해서는 활성 억제가 나타나진 않았다. The enzymatic properties of ${\beta}-amylase$ from soybean and sweet potato were compared. The sweet potato enzyme consists of four identical subsunits whereas soybean enzyme has no subunit $structure^{12,\;15)}$. In the denatured state, both enzymes exhibited the same molecular weight on SDS-gel electrophoresis and on gel-filtration analysis. The spectra of circular dichroism revealed that both enzyme have almost same secondary structure but the environment of aromatic side chains are different. The chemical cleavage of soybean and sweet potato ${\beta}-amylases$ at cysteine residues and methionine residues demonstrated the homology of amino acid sequence between the enzymes. The similarity between soybean and sweet potato ${\beta}-amylase$ was also revealed by immunological method. The antibody for soybean enzyme inhibited the activity of sweet potato enzyme but it did not inhibit the activity of wheat, barley and Japanese-raddish ${\beta}-amylases$.

Objective: To investigate the effect on early mobilization in patients undergoing extra-corporeal membrane oxygenation (ECMO) and acute blood purification therapy in the intensive care unit (ICU).Methods: We conducted this multicenter retrospective cohort study by collecting data from six ICUs in Japan. Consecutive patients who were admitted to the ICU, aged ≥18 years, and received mechanical ventilation for >48 hours were eligible. The analyzed were divided into two groups: ECMO/blood purification or control group. Clinical outcomes; time to first mobilization, number of total ICU rehabilitations, mean and highest ICU mobility scale (IMS); and daily barrier changes were also investigated.Results: A total of 204 patients were included in the analysis, 43 in the ECMO/blood purification group and 161 in the control group. In comparison of clinical outcome, the ECMO/blood purification group had a significantly longer time to first mobilization: ECMO/blood purification group 6 vs. control group 4 (p=0.003), higher number of total ICU rehabilitations: 6 vs. 5 (p=0.042), lower mean: 0 vs. 1 (p=0.043) and highest IMS: 2 vs. 3 (p=0.039) during ICU stay. Circulatory factor were most frequently described as barriers to early mobilization on days 1 (51%), 2 (47%), and 3 (26%). On days 4 to 7, the most frequently described barrier was consciousness factors (21%, 16%, 19%, and 21%, respectively)Conclusion: The results of this study comparing the ECMO/blood purification group and the untreated group in the ICU showed that the ECMO/blood purification group had significantly longer days to mobilization and significantly lower mean and highest IMS.

The chemical cleavage of soybean and sweet potato β-amylases at cysteine residues and methionine residues demonstrated the homology of amino acid sequence between the enzymes. The similarity between soybean and sweet potato β-amylase was also revealed by immunological method. The antibody for soybean enzyme inhibited the activity of sweet potato enzyme but it did not inhibit the activity of wheat, barley and Japanese-rad-dish β-amylases.
