Information on airborne microplastics (AMPs) in Thailand is still not available. This study monitored and identified AMPs Bangkok Metropolitan Region (BMR), Thailand. A high-volume air sampler was used to collect at five different locations BMR. These are university, roadside, urban park, dumpsite, industrial estate. The results showed that concentration averaged 333.42 ± 142.99 per cubic meter...

biologic crystals and particles (BCP) in this report were shown in the first paper of this series (13) as large (up to 300 z in length) RNA-staining objects (pyronin response; controlled by RNase) which appeared in cul tures of chick embryo tissues viewed by phase-contrast microscopy. Their pleomorphic shapes were described as either semirigid tubules, right-handed helices (12), ribbons, rhombo...

new biodegradable network polymers containing siloxane-linked polymeric prodrugs of 5-ammino-2-hydroxybenzoic acid (5-asa) in the main chain were prepared by ter polymerization of methacrylic acid (ma), 2-hydroxyethylmethacrylate (hema), and bis (trimethylsilyloxy) methylsilane (vbm) in the presence of some new cross-linking agents.the monomers and polymers were characterized by ft-ir and 1h-nm...

1. Heparin has been shown to increase platelet aggregation by ADP and adrenaline and to enhance the platelet release reaction when tested in citrated platelet-rich plasma (P.R.P.). This activity is present when heparin is added to P.R.P. or when P.R.P. is prepared after intravenous injection of heparin, and when heparin is added to non-anticoagulated native P.R.P. 2. Retention of platelets by c...
