Abstract
A rapid and efficient DNA extraction method was developed for detecting mastitis pathogens in milk. The first critical step involved cell wall disruption by bead-beating, as physical disruption using beads was more effective for DNA extraction from Gram-positive bacteria, such as Staphylococcus aureus, than enzymatic disruption using proteinase K. The second critical step involves the use of acetic acid and ammonium sulfate in the purification process, as these reagents effectively and efficiently remove the lipids and proteins in milk. Using these methods, DNA suitable for loop-mediated isothermal amplification was obtained within 30 min. Also, the rapid and sensitive detection of S. aureus in milk was possible at levels as low as 200 cfu/ml.

Abstract
BACKGROUND The perioperative immune status of colorectal robotic surgery (RS), laparoscopic surgery (LS), and open surgery (OS) patients has not been compared. Our aim was to evaluate perioperative stress and immune response after RS, LS and OS. METHODS This prospective study included 46 colorectal surgery patients from the Department of Surgical Oncology of the University of Tokyo Hospital. Peripheral venous blood samples were obtained preoperatively and on postoperative days 1, 3, and 6. We evaluated expression of HLA-DR (marker of immune competence), C-reactive protein (CRP) levels, and lymphocyte subset counts (natural killers, cytotoxic T cells and helper T cells). RESULTS Fifteen, 23, and 8 patients underwent RS, LS and OS, respectively. HLA-DR expression was the lowest on day 1 and gradually increased on days 3 and 6 in all the groups. There was no significant difference in postoperative HLA-DR expression between the RS and LS group. However, on day 3, HLA-DR expression in the RS group was significantly higher than in the OS group (p = 0.04). On day 1, CRP levels in the LS group were significantly lower than in the RS group (p = 0.038). There were no significant perioperative changes in the lymphocyte subset cell count between the three groups. CONCLUSIONS Perioperative surgical stress, as evaluated by immunological parameters, was comparable between robotic and laparoscopic surgery and higher with open surgery. Robotic surgery may be an alternative to laparoscopic surgery, as a minimally invasive surgery option for colorectal cancer.

Abstract
Evidence shows that forced expression of the PDX1 gene converts hepatoma cells, mouse liver epithelial cells (MLECs) and HepaRG cells, into insulin—producing cells, β—cells, or islets of Langerhans. However, no reports have investigated the characteristics of mouse or human hepatocytes introduced with the PDX1 gene over prolonged observation periods. In this study, we immunohistologically and molecularly investigated the alternative processes induced by PDX1 gene introduction in mouse and human hepatocytes over prolonged observation periods using immunocytochemistry, immunofluorescence, polymerase chain reaction (PCR), Western blotting, and flow cytometry (FCM) analysis. Immunocytochemical and immunofluorescent observations showed that MLECs and HepaRG cells on 2 and 21 days after introduction of the PDX1 gene comprised cells double—positive for insulin and albumin. Additionally, they showed MAFA expression and glucose—responsive insulin secretion with glucokinase expression. However mouse embryonic fibroblasts introduced with PDX1—GFP could not acquire glucose—responsive insulin secretion and glucokinase expression. Subsequently, we hypothesized that the number of albumin—positive MLECs and HepaRG cells would decrease after introduction of PDX1 due to the conversion of MLECs and HepaRG cells into insulin—producing cells. However, FCM analysis indicated that the number of albumin—positive MLECs and HepaRG cells was not altered by the introduction of PDX1. We thought that MLECs and HepaRG cells introduced with the PDX1 gene could acquire a functional insulin secretory capacity without conversion to β—cells, or islets of Langerhans, and the acquisition could need glucokinase expression.

Abstract
BACKGROUND Cluster of differentiation 147 (CD147)/basigin on the malignant tumor cell surface is critical for tumor proliferation, invasiveness, metastasis, and angiogenesis. CD147 expressed on malignant melanoma cells can induce tumor cell invasion by stimulating the production of matrix metalloproteinases (MMPs) by surrounding fibroblasts. Membrane vesicles, microvesicles and exosomes have attracted attention, as vehicles of functional molecules and their association with CD147 has been reported. Cleaved CD147 fragments released from tumor cells were reported to interact with fibroblasts. We investigated the intercellular mechanisms by which CD147 stimulates fibroblasts to induce MMP2 activity. MATERIALS AND METHODS CD147 was knocked-down using short hairpin RNA (shRNA). The stimulatory effect of CD147 in cell culture supernatants, microvesicles, and exosomes on the enzymatic activity of MMP2 was examined by gelatin zymography. RESULTS Supernatants from A375 control cells induced increased enzymatic activity of fibroblasts; such activity was significantly lower in CD147 knock-down cells. CONCLUSION Cleaved CD147 plays a pivotal role in stimulating fibroblasts to induce MMP2 activity.

Abstract
The aim of the present study was to examine changes in innate immune factors in the milk of mastitic dairy cows treated with antibiotics. Cows in the antibiotics group (n = 13) were infused into the mammary gland with cefazolin on the sixth day after mastitis was diagnosed (the day of the mastitis diagnosis = day -6). The control group (n = 12) was not treated. Milk samples were collected once every 2 days from days -6 to 12 and somatic cell count (SCC), lingual antimicrobial peptide (LAP), and lactoferrin (LF) concentrations and lactoperoxidase (LPO) activity were measured. SCC and LF concentrations in the antibiotics group markedly decreased after the antibiotic treatment. When cows in the antibiotics group were divided according to SCC on day 0, LAP concentrations and LPO activity in cows with a lower SCC on day 0 (<5 × 10(6) cell/mL) were significantly higher and lower than those in cows with a higher SCC, respectively. These results suggest that LF concentration decreased with decrease in SCC after treatment and that LAP concentration and LPO activity differed depending on the severity of mastitis. This is the first report to reveal the dynamics of innate immune factor in milk of cows treated for clinical mastitis.

Abstract
We describe an adult patient with Henoch-Schönlein purpura who had arthralgia, severe abdominal pain, and low plasma factor XIII activity. Corticosteroids were not used because of his history of multidrug-resistant pulmonary tuberculosis. Dapsone had no immediate effect on his abdominal pain, but appeared to have some effect on the purpura and arthralgia. Marked improvement of the abdominal pain was observed immediately after the administration of factor XIII concentrate. Factor XIII concentrate may be useful for alleviating abdominal pain in Henoch-Schönlein purpura patients when corticosteroids are contraindicated

Abstract
Adult-onset Still disease (AOSD) is a systemic inflammatory disorder characterized clinically by high spiking fever, polyarthralgia/arthritis, a salmon-pink evanescent rash, predominantly neutrophilic leucocytosis, lymphadenopathy, liver dysfunction, and splenomegaly. Recently, a nonclassic, nonevanescent skin rash has been reported. We report a 27-year-old woman with AOSD showing persistent pruritic papular lesions. Histologically, dyskeratotic keratinocytes were seen in the upper epidermis. We describe this case in detail and review the previous literature. Nonclassic pruritic eruptions with characteristic dyskeratotic keratinocytes might provide an important clue for the diagnosis of AOSD.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) has rapidly emerged as a cause of severe and intractable skin infection. At present, there are no effective topical treatments, and infection or colonization by MRSA of the skin raises serious medical problems. We developed an ultrasonic levitation washer that generates silver ions (Ag(+)) and ozone (O3) to clean and sterilize medical devices. We report the effect of ultrasonic levitation (levitation) with Ag(+) and O3 on MRSA in vitro and in vivo. Antimicrobial effect against six MRSA strains of all agr types was examined under three in vitro conditions; cells floating in a water tank, cells infiltrating-, and cells forming a biofilm on an atelocollagen membrane. In the in vivo studies, we assayed the number of MRSA organisms that survived treatment on murine skin ulcers and evaluated the ulcer size. Levitation with Ag(+) dramatically decreased the survival of MRSA floating in a water tank. Levitation with Ag(+) and O3 significantly decreased the viability of MRSA that had infiltrated or formed a biofilm on atelocollagen membranes regardless of the level of biofilm production. In vivo studies showed that the number of MRSA on murine skin ulcers was significantly decreased when 15-min treatment was performed for 7 consecutive days and that the ulcer size was significantly decreased after the seventh treatment course. Levitation with Ag(+) and O3 may be a valuable tool for treating MRSA infestation of the skin and for accelerating wound healing.

Abstract
Mycoplasma spp. are highly contagious pathogens and intramammary Mycoplasma infection is a serious issue for the dairy industry. As there is no effective vaccine for Mycoplasma infection, control depends on good husbandry and chemo-antibiotic therapy. In this study, antimicrobial susceptibility of Mycoplasma strains recently isolated from cases of bovine mastitis in Japan was evaluated by minimum inhibitory concentration (MIC). All Mycoplasma bovis strains were sensitive to pirlimycin, danofloxacin and enrofloxacin, but not kanamycin, oxytetracycline, tilmicosin or tylosin. M. californicum and M. bovigenitalium strains were sensitive to pirlimycin, danofloxacin, enrofloxacin, oxytetracycline, tilmicosin and tylosin, but not to kanamycin. This is the first report to describe the MIC of major antimicrobial agents for Mycoplasma species isolated from bovine mastitis in Japan.
