Based on th. information of th. interdisciplinary task force on allergy diagnostics in th. metal branch.in 2001,th. German Contact Dermatitis Research.Group (DKG) compiled two metalworking fluid (MWF) test series with.currently and previously used components,respectively. After 2 years of patch.testing,we present results obtained with.th.se series,based on data of th. Information Network of Departments of Dermatology (IVDK). 251 metalworkers wh. were patch.tested because of suspected MWF dermatitis in 2002 and 2003 were included in th.s retrospective data analysis. Of th.se,206 were tested with.th. current MWF series and 155 with.th. h.storical MWF series. Among th. current MWF allergens,monoeth.nolamine ranked 1st with.11.6%positive reactions. Dieth.nolamine (3.0%)-,trieth.nolamine (1.1%),and diglycolamine (1.9%) elicited positive reactions far less frequently. Allergic reactions to paminoazobenzene were frequently observed (6.0%),but th. relevance of th.se reactions is still obscure. Positive reactions to biocides ranged from 4.5%for Bioban. CS 1135 to 0.5%for iodopropynyl butylcarbamate and 2-ph.noxyeth.nol. Concomitant reactions to formaldeh.de,wh.ch.caused positive reactions in 3.3%,and formaldeh.de releasers occurred to varying extents with.ut conclusive pattern. No positive reactions were seen to dibutyl ph.h.late,di-2-eth.lh.xyl ph.h.late,tricresyl ph.sph.te,isopropyl myristate or benzotriazole. With.th. h.storical MWF test series,positive reactions to meth.ldibromo glutaronitrile (MDBGN) were observedmost frequently. h.wever,sensitization via allergen sources oth.r th.n MWF seems likely,as MDBGN,during th. study period,h.s been one of th. most frequent preservative allergens in cosmetics and body care products. Oth.r h.storical MWF allergens comprisedmorph.linyl mercaptobenzoth.azole (3.3%),benzisoth.azolinone (BIT; 2.0%) and Bioban. P 1487(1.3%). BIT is currently used in MWF again,so it was sh.fted to th. current MWF test series. As decreasing reaction fre

Epoxy resin systems (ERSs) are a frequent cause of occupational allergic conta ct dermatitis. Sensitization occurs not only to th. resins, but also to h.rdener s and reactive diluents. h.wever, only a fraction of th. ERS components currentl y in use are available for patch.testing. With.th. multicentre study EPOX 2002, we attempted to improve diagnostics in th.s field by patch.testing with.componen ts currently used in ERSs. During th. first study period (October 2002 to July 2 003), in addition to commercially available ERS patch.test substances, 16 study substances (1 resin, 9 h.rdeners and 6 reactive diluents) were patch.tested in 7 0 patients with.suspected contact allergy due to ERSs and 22 patients with.a pri or positive patch.test reaction to epoxy resin (ER) in th. standard series. Most frequently, allergic reactions to ER based on diglycidyl eth.r of bisph.nol A a nd F were observed (55.2%and 43.7%, respectively). Agreement between positive reactions to both.resins, wh.ch.can be explained by immunological cross-sensiti zation and/or coexposure, was substantial [Coh.n’s kappa 0.65 (95%CI:0.49-0 . 80)]. Among th. reactive diluents, 1,6-h.xanediol diglycidyl eth.r (1,6-h.DGE ) and 1,4-butanediol diglycidyl eth.r (1,4-BDDGE) were th. most frequent allerg ens, with.19.5%and 18.4%positive reactions, respectively. Alth.ugh.agreement b etween positive reactions to 1,6-h.DGE and 1,4BDDGE was even better th.n with.t h. 2 resins, th. sample size is considered too small to decide reliably wh.th.r 1,6-h.DGE alone could serve as a marker allergen for both. Allergic reactions t o p-tert-butylph.nyl glycidyl eth.r and to ph.nyl glycidyl eth.r (PGE) occurre d in 11.5%of th. patients tested, with.only moderate agreement. All patients po sitive to cresyl glycidyl eth.r (6.8%) also reacted to PGE. Of th. h.rdeners te sted, m-xylylene diamine was th. most frequent allergen (13.8%), followed by i soph.rone diamine (5.7%). No reactions were observed to several substances, th. tes

Sporadic cases of contact allergy to wh.te petrolatum, wh.ch.is used as a veh.cle in patch.test preparations, h.ve been reported. Th. quantitative relevance of th. ph.nomenon remains yet to be elucidated. Meth.ds: Retrospective analysis of patch.test data of th. Information Network of Departments of Dermatology (IVDK, h.tp://***) between 1992 and 2004. Results: Analysis of 79 365 patients patch.tested with.pure petrolatum yielded 27 ‘ + ’ (0.03% ) and 2 ‘ + + + ’ (0.003% ) reactions. Th. majority of non-negative reactions (0.3% ) was interpreted as doubtful (235) or mild irritant (32). Th. negative reaction index (RI) (- 0.8), and th. h.gh.positivity ratio (PR) (93% ) especially a lack of concordance with.patch.test preparations containing ≥ 99% petrolatum indicate th.t many of th. ‘ positive’ (+ ) reactions h.ve to be considered as irritant. Th.re were 2 ‘ + + + ’ reactions. In 1 case, an ‘ angry back reaction’ was confirmed. Th. oth.r case is probably a reading or documentation error, as th. majority of patch.test reactions to preparations containing petrolatum remained negative in th.s case also. Conclusions: True allergic patch.test reactions to wh.te petrolatum are extremely rare and probably due to an individually increased susceptibility to allergens and/or irritants. Th.s is in agreement with.considering petrolatum as a non-sensitizer.

CLEAN ENERGY 2024年第2期8卷 27-34页

作者： Vasilikos, N. Georgantopoulou, C. Alajaimi, h. Almajed, S. h. Ah.ed, M. Math.oulakis, D. Bah.ain Polytech Sch Mech Engn POB 33349 Isa Town Bahrain Natl Tech.Univ Ath.ns Sch Mech Engn Heroon Polytech 7 St Athens 15773 Greece

In th. present work, tilted global solar irradiance data are presented and analysed, measured for a period of 1 year on th. campus of Bah.ain Polytech.ic, Kingdom of Bah.ain, from both.a fixed ph.tovoltaic panel and a moving one via a two-axis solar tracker. Th. fixed panel faces south.with.an angle of 26 degrees with.respect to th. h.rizontal, coinciding with.th. local geograph.cal latitude. Th. second panel is moved by two motors, controlled by a global positioning system and suitable software so th.t th. Sun's rays are perpendicular to th. panel surface. A pyranometer is installed on each.panel, recording th. tilted global solar irradiance, stored by using a data logger. Th. analysis of th. data obtained sh.ws a 33% solar energy gain on an annual basis for th. moving panel (2780 versus 2088 kWh.m2 on th. fixed panel). More importantly, in June, wh.n th. energy demand in Bah.ain is elevated due to th. increased residential cooling loads, th. solar energy received by th. moving panel is 54.7% h.gh.r compared with.th.t of th. fixed panel. On a percentage basis, th. increase in solar energy from th. moving panel is profound in th. early morning and late evening h.urs. Moreover, th. reduction in th. solar energy received by th. fixed panel from May to June does not appear in th. moving panel because of th. adjustable orientation of th. latter. Th.ough.ut th. year, th. mean daily solar power varies between 0.37 and 0.56 kW/m2 for th. fixed panel, and 0.45 and 0.70 kW/m2 for th. moving panel. In winter, solar energy fluctuations are elevated due to erratic weath.r conditions th.t present a peak standard deviation of 28% of th. corresponding mean. Th. data presented are useful for potential solar investments in Gulf countries. Tilted global solar irradiance data are measured and analysed for a period of 1 year on th. campus of Bah.ain Polytech.ic, Kingdom of Bah.ain, from both.a fixed ph.tovoltaic panel and a moving one via a two-axis solar tracker.

In view of th. wide variety of components currently used in metalworking fluids (MWF), relevant contact sensitizations may be overlooked, because commercially available MWF test series cannot cover th. full spectrum. h.nce, patch.testing with.MWF from th. patient’s workplace is an important additional diagnostic tool. h.wever, recommendations on h.w to perform such.patch.tests vary. We retrospectively analyzed patch.test data of th. Department of Dermatology in Dortmund, 1992-2003. In 141 metalworkers tested because of suspected occupational contact dermatitis due to MWF, 829 patch.tests with.306 samples of MWF were performed. Water-based MWF (wb MWF) were mainly tested in 2 dilution series, i.e. pure (workplace concentration), 10%aq. and 1%aq., and pure, 50%aq. and 10%aq. Positive reactions to wb MWF occurred in 27 patients. Patch.testing with.wb MWF at workplace concentration resulted in 16.1 %(39/242) positive reactions, with.a positivity ratio of 69%and a reaction index of 0. From th. analysis of reaction patterns and concomitant reactions,we conclude th.t most of th.se positive reactions indicated true contact allergy. With.lower concentrations, relevant allergic reactions may be missed. Neat oils were tested as is or diluted from 1 to 50%in olive oil, but no reactions at all were observed. For optimum benefit of patch.testing with.MWF from th. patient’s workplace, breakdown testing is recommended. To overcome th. time-consuming difficulties associated with.th.s procedure, we propose a centre for information and documentation of contact allergies due to occupational exposure. Furth.rmore, full declaration of MWF ingredients is desirable.

Th. potential of glutamine supplementation in reduced-crude protein diets for ch.cken-meat production

引用

ANIMAL NUTRITION 2024年第3期18卷 49-56页

作者： Selle, Peter h. Macelline, Sh.mil P. Togh.ani, Meh.i Liu, Sonia Yun Univ Sydney Poultry Res Fdn Camden NSW 2570 Australia Univ Sydney Sydney Sch Vet Sci Camden NSW 2570 Australia Univ Sydney Fac Sci Sch Life & Environm Sci Camden NSW 2570 Australia

Th.s review explores th. potential of including glutamine, a so-called non-essential amino acid, in th. formulation of reduced-crude protein (CP) diets for broiler ch.ckens. Th.re is a precedent for benefits wh.n including glycine and serine in reduced-CP diets. Fundamentally th.s is due to decreases in nonessential amino acid concentrations in reduced-CP diets d an unavoidable consequence of reducing CP with.ut amino acid supplementation. Th. situation for glutamine is complicated because analysed dietary concentrations are very rarely provided as standard assays do not differentiate between glutamine and glutamate and are reported on a combined basis as glutamic acid. Th. dietary requirement for glutamic acid is approximately 36.3 g/kg but it is increasingly unlikely th.t th.s requirement will be met as dietary CP levels are progressively reduced. Glutamine is an abundant and versatile amino acid and constitutes 50.5 mg/g of wh.le-body ch.cken protein and is th. dominant free amino acid in systemic plasma wh.re it h.s been sh.wn to provide 22.6% (139.9 of 620.3 mg/mL) of th. total in birds offered 215 g/kg CP, wh.at-based diets. In addition to dietary intakes, glutamine biosynth.sis is derived mainly from th. condensation of glutamate and ammonia (Nh.) catalysed by glutamine synth.tase, a reaction th.t is pivotal to Nh. detoxification. Glutamate and Nh. are converted to glutamine by ph.sph.tedependent glutaminase in th. reciprocal reaction; th.s, glutamine and glutamate are interch.ngeable amino acids. h.wever, th. rate of glutamine biosynth.sis may not be adequate in rapidly growing broiler ch.ckens and exogenous and endogenous glutamine levels are probably insufficient in birds offered reduced-CP diets. Th. many functional roles of glutamine, including Nh. detoxification and maintenance of acid-base h.meostasis, th.n become relevant. Twenty feeding studies were identified wh.re dietary glutamine supplementation, usually 10 g/kg, was evaluated in birds kept under

Objective: Botulinum toxin type A is frequently used to treat crow's feet lines. h.wever, th. optimal dose and injection sites are still controversial. Th. objective of th.s study was to compare th. efficacy of different botulinum toxin type A injection patterns for th. treatment of crow's feet. Meth.ds: Th.s single-center, retrospective, clinical study was conducted at th. National h.spital of Dermatology and Venereology from July 2020 to December 2020. Data on 60 patients with.crow's feet were collected and divided into 2 groups (3- or 4-point intramuscular injection) according to th. intramuscular injection tech.ique th. patients received. Th. treatment efficacy was assessed based on th. ch.nges in th. Crow's Feet Grading Scale score at 1, 4, and 16 weeks after treatment. Repeated measures analysis of variance was used for th. assessment of ch.nges in scores over time between th. two groups. Results: After treatment, th. average Crow's Feet Grading Scale score was significantly decreased compared with.th. pretreatment score at all timepoints (1, 4, and 16 weeks) in both.states (dynamic: For 3-point intramuscular injection tech.ique, 1 week: 1.90 ± 0.71 vs. 2.97 ± 0.56; 4 weeks: 1.87 ± 0.68 vs. 2.97 ± 0.56; 16 weeks: 2.60 ± 0.67 vs. 2.97 ± 0.56. For 4-point intramuscular injection tech.ique, 1 week: 1.73 ± 0.83 vs. 3.03 ± 0.49; 4 weeks: 1.73 ± 0.74 vs. 3.03 ± 0.49; 16 weeks: 2.57 ± 0.68 vs. 3.03 ± 0.49, all P h.ique, 1 week: 1.20 ± 0.89 vs. 2.20 ± 0.85; 4 weeks: 1.20 ± 0.89 vs. 2.20 ± 0.85; 16 weeks: 1.87 ± 0.97 vs. 2.20 ± 0.85; For 4-point intramuscular injection tech.ique, 1 week: 1.50 ± 0.86 vs. 2.30 ± 0.84; 4 weeks: 1.33 ± 0.84 vs. 2.30 ± 0.84; 16 weeks: 1.87 ± 0.97 vs. 2.30 ± 0.84.

Detecting anomalies in blockch.in transactions using mach.ne learning classifiers and explainability analysis

引用

BLOCKCh.IN-RESEARCh.AND APPLICATIONS 2024年第3期5卷 106-122页

作者： h.san, Moh.mmad Rah.an, Moh.mmad Sh.h.iar Janicke, h.lge Sarker, Iqbal h. Premier Univ Dept Comp Sci & Engn Chitagong 4000 Bangladesh United Int Univ Dept Comp Sci & Engn Dhaka 1212 Bangladesh Cyber Secur Cooperat Res Ctr Perth 6027 Australia Edith.Cowan Univ Ctr Securing Digital Futures Perth 6027 Australia

As th. use of blockch.in for digital payments continues to rise, it becomes susceptible to various malicious attacks. Successfully detecting anomalies with.n blockch.in transactions is essential for bolstering trust in digital payments. h.wever, th. task of anomaly detection in blockch.in transaction data is ch.llenging due to th. infrequent occurrence of illicit transactions. Alth.ugh.several studies h.ve been conducted in th. field, a limitation persists: th. lack of explanations for th. model's predictions. Th.s study seeks to overcome th.s limitation by integrating explainable artificial intelligence (XAI) tech.iques and anomaly rules into tree-based ensemble classifiers for detecting anomalous Bitcoin transactions. Th. sh.pley additive explanation (Sh.P) meth.d is employed to measure th. contribution of each.feature, and it is compatible with.ensemble models. Moreover, we present rules for interpreting wh.th.r a Bitcoin transaction is anomalous or not. Additionally, we introduce an under-sampling algorith. named XGBCLUS, designed to balance anomalous and non-anomalous transaction data. Th.s algorith. is compared against oth.r commonly used under-sampling and over-sampling tech.iques. Finally, th. outcomes of various tree-based single classifiers are compared with.th.se of stacking and voting ensemble classifiers. Our experimental results demonstrate th.t: (i) XGBCLUS enh.nces true positive rate (TPR) and receiver operating ch.racteristic-area under curve (ROC-AUC) scores compared to state-of-th.-art under-sampling and over-sampling tech.iques, and (ii) our proposed ensemble classifiers outperform traditional single tree-based mach.ne learning classifiers in terms of accuracy, TPR, and false positive rate (FPR) scores.
