The increased use of pesticides in crop production, especially in Santa, has left consumers with great fear and uncertainty regarding the fate of residues after consumption in the human body. This study was aimed at performing a multi-residue analysis of crop samples to detect and quantify pesticide residues present, and thus determine their level of contamination. Twelve (12) crop samples (4 samples each of Solanum tuberosum (Irish potato), Solanum lycopersicum (tomato), Capsicum annum (sweet pepper) and Apium graveolens (celery)), were randomly collected from four villages in Santa. The samples were analyzed using the QuEChERS Buffered AOAC 2007.01 method. The results showed the presence of pesticide residues in 58.3% of the samples. Cypermethrin and chlorpyrifos insecticides were detected, though cypermethrin was found in traces. After quantification, the concentration of chlorpyrifos was determined to be far above the CODEX Maximum Residue Limits (MRLs) in 28.6% of the samples. Samples with this high concentration of chlorpyrifos were: tomato from Pinyin and Baligham (2.0 and 1.8 μg/g respectively), whereas the Codex MRLs for tomato is 1.0 μg/g. This study raised concerns on the contamination of some garden crops by pesticide residues and calls for the assessment of the health situation of consumers and the analysis of pesticide residues in drinking water resources in this area.

SOC Turnover and Lime-CO<sub>2</sub>Evolution during Liming of an Acid Andisol and Ultisol

引用

Open Journal of Soil Science 2011年第2期1卷 49-53页

作者： Wilfredo A. Dumale Jr. Tsuyoshi Miyazaki Kenta Hirai taku Nishimura Department of Plant Science Nueva Vizcaya State University Bayombong Nueva Vizcaya Philippines Department of Biological and Environmental Engineering University of Tokyo Tokyo Japan.

Agricultural liming contributes significantly to atmospheric CO2 emission from soils but data on magnitude of lime- contributed CO2 in a wide range of acid soils are still few. Data on lime-contributed CO2 and SOC turnover for global acid soils are needed to estimate the potential contribution of agricultural liming to atmospheric CO2. Using Ca13CO3 (13C 99%) as lime and tracer, here we separated lime-contributed and SOC-originated CO2 evolution in an acidic Kuroboku Andisol from Tanashi, Tokyo Prefecture (35°44′ N, 139°32′ E) and Kunigami Mahji Ultisol of Nakijin, Okinawa Prefecture, Japan (26°38′ N, 127°58′ E). On the average, lime-CO2 was 76.84% (Kuroboku Andisol) and 66.36% (Kunigami Mahji Ultisol) of overall CO2 emission after 36 days. There was increased SOC turnover in all limed soils, confirming priming effect (PE) of liming. The calculated PE of lime (Kuroboku Andisol, 51.97% - 114.95%;Kunigami Mahji Ultisol, 10.13% - 35.61%) was entirely 12C turnover of stable soil organic carbon (SOC) since SMBC, a labile SOC pool, was suppressed by liming in our experiment. Our results confirmed that mineralization of lime-carbonates is the major source of CO2 emission from acid soils during agricultural liming. Liming can influence the size of CO2 evolution from agricultural ecosystems considering global extent of acid soils and current volume of lime utilization. We propose the inclusion of liming in simulating carbon dynamics in agricultural ecosystems.

We report our experience with two cases of anterolateral thigh flaps based on the musculocutaneous perforators arising from a more distal part of the descending branch than in the conventional anterolateral thigh flap. Case 1: A 53-year-old man with a skin ulcer over the anterior surface of the left tibia secondary to plate fixation for an open fracture. The perforator marked with preoperative Doppler was located 8 cm proximal to the superior border of the patella. Without thinning, the flap was 10 × 4 cm in size and 5 mm thick. Case 2: A 46-year-old man with necrosis of the right index finger after replantation. The flap was 5 × 3 cm in size and 3 mm in thickness. This “distal” anterolateral thigh flap can be raised as a quite thin flap with a long pedicle and, therefore, is considered useful in the reconstruction of various soft tissue defects.

Cell Proliferation Inhibition by Sericin from the Wild Silkworm, Cricula trifenestrata

引用

Advances in Biological Chemistry 2016年第1期6卷 28-33页

作者： Wenqi Liu Mayumi Karimazawa taku Ozaki Ying An Masao Miyazaki Koichi Suzuki Ken-ichi Tsutsumi Tetsuro Yamashita United Graduate School of Agricultural Sciences Iwate University Morioka Japan Office of Research Exchange Iwate University Morioka Japan Research Center for Child Mental Development Hirosaki University Graduate School of Medicine Hirosaki Japan

Sericin is a major silk protein, and recent studies have shown that sericin has numerous physiological activities against cultured cells. For example, it accelerates mammalian cell proliferation and protects insect cells against cell death. In this study, we examined the activities of sericin prepared from the wild silkworm, Cricula trifenestrata. The results presented here indicated that C. trifenestrata sericin has anti-proliferative activity against feline kidney cells, while sericin from Bombyx mori promoted cell proliferation. The components of the sericin preparation that played a role in inhibition of proliferation were analyzed by fractionation through partition chromatography (Folch method) and reversed-phase chromatography. Our analysis showed that at least two components in the C. trifenestrata sericin preparation promoted the anti-proliferative activity in an additive or even synergistic manner. Therefore, differences in components between insect species may contribute to different activities against cultured cells.

Application of appropriate use criteria for percutaneous coronary intervention in Japan

引用

World Journal of Cardiology 2016年第8期8卷 456-463页

作者： taku Inohara Shun Kohsaka Ikuko Ueda Takashi Yagi Yohei Numasawa Masahiro Suzuki Yuichiro Maekawa Keiichi Fukuda Department of Cardiology Hiratsuka City Hos-pital Department of Cardiology Keio University School of Medicine Keio inter--hospital Cardiovascular Studies

The aim of this review was to summarize the concept of appropriate use criteria(AUC) regarding percutaneous coronary intervention(PCI) and document AUC use and impact on clinical practice in Japan, in comparison with its application in the United States. AUC were originally developed to subjectively evaluate the indications and performance of various diagnostic and therapeutic modalities, including revascularization techniques. Over the years, application of AUC has significantly impacted patient selection for PCI in the United States, particularly in non-acute settings. After the broad implementation of AUC in 2009, the rate of inappropriate PCI decreased by half by 2014. The effect was further accentuated by incorporation of financial incentives(e.g., restriction of reimbursement for inappropriate procedures). On the other hand, when the United States-derived AUC were applied to Japanese patients undergoing elective PCI from 2008 to 2013, about one-third were classified as inappropriate, largely due to the perception gap between American and Japanese experts. For example, PCI for low-risk non-left atrial ascending artery lesion was more likely to be classified as appropriate by Japanese standards, and anatomical imaging with coronary computed tomography angiography was used relatively frequently in Japan, but no scenario within the current AUC includes this modality. To extrapolate the current AUC to Japan or any other region outside of the United States, these local discrepancies must be taken into consideration, and scenarios should be revised to reflect contemporary practice. Understanding the concept of AUC as well as its perception gap between different counties will result in the broader implementation of AUC, and lead to the quality improvement of patients' care in the field of coronary intervention.
