We suggest that adjusted neutropenia is useful for predicting early serious infection in SLE patients during the first follow-up year.

Benzo [a]pyrene, a polycyclic aromatic hydrocarbon (PAH) whose metabolites are mutagenic and highly carcinogenic, is listed as a Group 1 carcinogen by the IARC. In this study, Arabica and Robusta green coffee beans were roasted under controlled conditions and the formation of benzo[a]pyrene during the roasting process was monitored. The concentration of benzo[a]pyrene in ground coffee and brewed coffee were determined by a HPLCfluorescence detector. The limit of detection (LOD) and limit of quantitation (LOQ) of benzo(a)pyrene were 0.03 and 0.09 μg/kg, respectively. Benzo[a]pyrene was only detected in the dark roast of ground coffee, with a concentration ranging from 0.147～0.757 μg/kg. The content of benzo[a]pyrene in Ethiopia Mocha Harrar G4 is the highest (0.757 μg/kg).

초록: 2-Ethylhexyl acrylate와 2-hydroxyethyl acrylate의 기본 구조에 다양한 곁사슬 화학구조를 가지는 단량체의 종류를 변화시키면서 광중합된 고투명 3원 공중합체 시럽을 합성하 였다. 시럽에 가교제로 1,6-hexanediol diacrylate와 광개시제 를 혼합한 후 UV-광원을 조사시켜 점착제(PSAs)를 제조하여 점착특성과 광학특성을 고찰하였다. PSAs의 점착물성은 단량 체 종류에 따른 조성비에 크게 의존하고 있으나, 광학적 특성 이 유사함을 확인하였다. 상대적으로 부피가 큰 분자이면서 헤 테로 원소를 포함하고 있는 IBOA, THFA, ACMO 단량체가 n-BA, VAc, CHA 단량체보다 좋은 점착물성을 보여주었다.Abstract: To prepare transparent acrylic pressure sensitive adhesives (PSAs), terpolymer syrups were photopolymerized from 2-ethylhexyl acrylate and 2-hydroxyethyl acrylate with third monomer having different chemical structure. After polymerization, 1,6-hexanediol diacrylate as a crosslinker and a photoinitiator were added and then UV-irradiated to prepare the PSAs. The adhesion performances and optical characteristics of the PSAs were investigated. Their adhesion performance was dependent on the composition of monomers in the polymer chain but optical properties were maintained at a suitable level. The PSAs prepared by bulky and heteroatom-containing monomers such as IBOA, THFA, and ACMO showed better adhesion performance than others.Keywords: pressure sensitive adhesive, photopolymerization, peel strength, tack, transmittance, acrylate monomer.
