Al toxicity in plants is related to the activity of Ae+ and AI­ hydroxy monomers in the soil solution, whereas Al complexed with ligands such as fluoride (F), s~lphate (SQ42-), and oxalate is not toxic. Estimation of toxic Al relies on measurement of "labile" Al after short contact times with colorimetric reagents or cation-exchange resins. However, shifts in equilibrium may result in non-toxic...

A new green method for trace level quantification of four herbicides, glyphosate (GLYP), glufosinate (GLUF), and their main metabolites, aminomethylphosphonic acid (AMPA) 3-(methyl-phosphinico)-propionic (MPPA), was developed. The purification step without any derivatization conducted by solid-phase extraction using Chelex-100 resin in the Fe (III) form, followed elution with 5% NH4OH. analytes...

Abstract Background The artificial mussel (AM) is a passive sampling device that was originally developed for monitoring metal concentrations in the marine environment, but also increasingly used freshwater environments. AM consists of non-permeable Perspex tube, which closed on both sides with semi-permeable membrane. space between contains Chelex-100 beads, bind metals. allows determination d...

Abstract Sardinella lemuru resources are abundant, nutritious, high omega-3 and have economic value in artisanal fisheries. Its production volume landed for over a decade, but the most significant increase was peak southeast monsoon 2019 at Canggu fishing ground. However, prior-conventional kinship assessments genetically need to be confirmed. These research objectives encompass both molecular ...


 Identifikasi individu merupakan suatu hal yang sangat penting dalam forensik. DNA dapat diperoleh dari seluruh bagian tubuh dengan profil sama pada setiap orang. Epitel mukosa mulut salah satu sumber sering digunakan untuk identifikasi karena pengambilannya menggunakan metode swab tidak menyakiti probandus. Merokok perilaku banyak dilakukan oleh anak-anak muda/remaja. Asap rokok mempenga...

A method for detection and genotyping of genital Chlamydia trachomatis infections based on omp1 gene amplification and sequencing was developed. DNA was extracted from urogenital or urine samples using a Chelex-based method, and an approximately 1,100-bp-long fragment from the omp1 gene was directly amplified and sequenced. Genotyping was performed by BLAST similarity search, and phylogenetic t...

AIM To report on the successful analysis of amplicons obtained with PowerPlex® Fusion 6C System, a highly robust 27-plex genotyping kit developed for human identification laboratories, on the Applied Biosystems® 3500 Genetic Analyzer. METHOD We performed characterization and evaluation studies following the Scientific Working Group on DNA Analysis Methods (SWGDAM) validation guidelines, exami...
