Résumé :
Understanding the factors controlling stability against mineralisation of soil organic matter is important for predicting changes in carbon stocks under changed environment or management. Soil carbon dynamics in oil palm plantations are little studied and have some characteristics that are unusual compared with other agricultural soils, such as high management-induced spatial variability and warm moist conditions. The aim of this work was to determine the factors controlling the mineralisability of the intermediate-stability carbon fraction of volcanic ash surface soils (0–5 and 15–20 cm depth) from oil palm plantations in Papua New Guinea. Soils with carbon contents of 2.2–35.2%, from areas with low and high organic matter inputs, were incubated for up to 812 days and soil respiration was measured periodically. Mean carbon turnover rates were 0.18–1.58, 0.07–0.23 and 0.03–0.07 a–1 on Days 54, 379 and 812 respectively. Turnover rate was initially (Day 54) correlated with pre-incubation total carbon content (r = 0.88), the ratio of permanganate-oxidisable carbon to total carbon (r = 0.62) and the ratio of oxalate-extractable Al and Fe to total carbon (r = –0.51 and –0.54 respectively), but the correlations decreased with time, being insignificant on Day 812. In the soils that had changed from C4 grassland 25 years previously, turnover rate was negatively correlated with δ13C, which increased with depth, but δ13C did not change significantly over the course of the incubation. Temperature sensitivity of mineralisation varied little, despite large differences in soil properties and changes in mineralisation rate. This suggested that turnover rates were affected to similar extents by biochemical recalcitrance and physical protection, as these two factors influence temperature sensitivity in opposing directions. Physico-chemical protection of organic matter appeared largely related to interaction with poorly crystalline Al and Fe oxides.

Résumé :
The composition of urinary stones was predicted on the basis of the differences in their Hounsfield unit (HU) densities as detected by in vivo non-contrast helical computed tomography (NCHCT). A total of 87 stones, which had been obtained from patients admitted to the emergency department with acute flank pain, were analysed biochemically. These stones had been visualized by NCHCT before spontaneous passage, ureteroscopic extraction or surgical removal, and their HU densities had been recorded. The HU densities of the stones were compared with the results of biochemical analysis. The mean HU densities of the stones composed of calcium oxalate ( n = 54), struvite ( n = 19) and uric acid ( n = 14) were 812 ± 135, 614 ± 121 and 413 ± 143, respectively. The differences between the mean HU densities of these three stone types were statistically significant. This initial clinical study demonstrated that in vivo NCHCT analysis may be used to predict the composition of urinary stones.

Résumé :
An analytical cross-sectional study was conducted with 812 subjects aged 35-74 years in Prek Russey commune, Cambodia to detect some factors associated with severe periodontitis. Four calibrated examiners employed Community Periodontal Index (CPI) to ascertain periodontal pocket depth (PD) and loss of epithelial attachment (LA). A questionnaire was used to obtain tobacco and alcohol consumption habits. One hundred (12.3%) subjects had one or more sextants with ≥ 4mm PD and ≥ 6mm LA (severe periodontitis). Smoking, tobacco chewing and age were significantly associated with severe periodontitis in bivariate analysis while only age and quantified smoking remained significant in a logistic regression analysis. The impact of quantified smoking on severe periodontitis was almost negligible [OR: 1.0006 (95% CI: 1.0001, 1.001)] compared to that of age [OR ranged from 8.3 at 45-54 years to 22 at 65-74 years (95% CI: 3.1, 62.3)]. Nevertheless, both age and quantified smoking can be considered as factors associated with severe periodontitis in rural Cambodians. Asia Pac J Public Health 2004; 16(1): 50-53.

Résumé :
Deladenus prorsus n. sp., isolated from dunnage wood originating from Malaysia and intercepted in Ningbo port, P.R. China, is described and illustrated. The dunnage wood material appeared to have holes resembling the typical exit holes of wood-boring insects and have associated blue stain. The new species is characterised by the presence of both the mycophagous and infective forms (Deladenus consists of mycetophagous-only forms and those with known female dimorphism), the body length of 814 (670-1147) and 898 (812-979) μm for mycetophagous males and females, respectively, and 1129 (1114-1352) μm for the infective female, and by the very anterior position of the excretory pore which is situated at 30.7 (24.4-33.0), 30.6 (25.4-35.6) and 37.9 (27.3-39.7) μm for the mycetophagous males and females and infective females, respectively, and the distance that the excretory pore is located anterior to the hemizonid which is 82 (77-90), 74 (54-92) and 86 (64-106) μm for the mycetophagous males and females and infective females, respectively. The diagnostic value of the excretory pore and the hemizonid of the species of the genus are discussed. The ribosomal DNA ITS region was sequenced and analysed.

Résumé :
Moxibustion plays an important role in the prevention and treatment of diseases and the promotion of human health. In this study, the components in moxa smoke from Jiangxi Poai Biotechnology Co., Ltd., namely, Qing moxa sticks, were absorbed by five solvents (cyclohexane, ethyl acetate, n-butanol, anhydrous ethanol, and water) and identified by gas chromatography-mass spectrometry. The identification results of the smoke from the Qing moxa sticks that was absorbed in liquid are as follows: a total of 294 compounds were identified, including 139 in cyclohexane, 145 in ethyl acetate, 60 in n-butanol, 89 in anhydrous ethanol, and 77 in water, and of those, 112 toxic compounds were identified. Furthermore, Ingenuity Pathway Analysis software and the PubChem database were successfully applied to analyze the toxic compounds. There were 812 target proteins related to the toxic components, 25 molecular networks, and 54 biological pathways. The results showed that the toxic compounds of moxa smoke may have some side effects on the heart, liver, and kidney of humans. This study revealed that the components of moxa smoke are complex and diverse. Due to the findings of toxic compounds in moxa smoke, we recommend that moxibustion rooms should be equipped with ventilation equipment or enough artificial ventilation to ensure the health of patients and practitioners.

Résumé :
812 Background: Several studies have reported that patients with right-sided colon cancers (RCC) have more unfavorable responses to anti-epidermal growth factor receptor (EGFR) antibody therapy than those with left-sided colon cancers (LCC). One of the causes is that RCC have more frequently genetic mutations such as RAS, BRAF, and PIK3CA than LCC. We investigated clinical outcomes of RCC patients treated with anti-EGFR antibody in the later line without these mutations. Methods: We reviewed 653 cases of colorectal cancer treated with anti-EGFR antibody from October 2009 to July 2017. There were 150 cases of RCC patients. Among them, 32 patients without KRAS status and 54 patients without enough genetic samples for gene re-analysis were excluded. We extracted 64 patients with status on RAS, BRAF, and PIK3CA , and finally enrolled 25 patients treated with anti-EGFR antibody plus irinotecan or anti-EGFR antibody alone in the later line. We analyzed the relationship of molecular status with clinical outcomes; overall response rate (RR), overall survival (OS) and progression-free survival (PFS) in this retrospective study. Results: Overall, there were 48% of cases with any mutations; among them 8.0% for KRAS, 4.0% for NRAS, 24.0% for BRAF and 4.0% for PIK3CA. Twenty percent of patients were treated as 2nd line therapy, while 72%, 16% treated as 3rd, 4th line therapy. RR of all cases, those whom without KRAS, RAS, RAS or BRAF, any mutations were 16.0%, 19.1%, 20.0%, 28.6%, 30.8%. The median OS and PFS in all wild-type patients were tended to be better than in those of all cases (OS; 14.9 vs. 11.6 months, hazard ratio = 0.70, p = 0.30, PFS; 8.17 vs. 5.37 months, hazard ratio = 0.67, p = 0.24). Conclusions: Even if primary tumors are in right-sided colon, in the enriched and selected patients anti-EGFR antibody therapy showed enough antitumor activity. Anti-EGFR antibody for RCC cases without using it at the front line is an effective option in the later line.
