In the last decade, Indonesia intensifies efforts to reduce pharmaceutical imports. One of initiatives is establishing a paracetamol production facility start operating in 2024. Kinetics study needed as basis design reactor. This investigated optimal temperature, reactant mole ratio, and agitation speed reactor for production. this study, aqueous solution para-aminophenol was reacted with aceti...

Burkholderia sp. strain AK-5 utilized 4-aminophenol as the sole carbon, nitrogen, and energy source. A pathway for the metabolism of 4-aminophenol in strain AK-5 was proposed based on the identification of three key metabolites by gas chromatography-mass spectrometry analysis. Strain AK-5 converted 4-aminophenol to 1,2,4-trihydroxybenzene via 1,4-benzenediol. 1,2,4-Trihydroxybenzene 1,2-dioxyge...

Based on the dramatic accelerating effect of 2-aminophenol, three ligands derived from 2-aminophenol were developed. Copper-catalyzed coupling reaction of nitrogen-containing nucleophiles with aryl bromides was efficiently carried out under mild conditions using 1,2,3,4-tetrahydro-8-hydroxyquinoline as a novel, simple, and versatile ligand.

This study evaluated the influence of methacrylic acid (MA) incorporation on hardness, roughness, and flexural strength of a denture base acrylic resin. Thirty-two circular and 40 rectangular specimens were divided into four groups, according to the concentration of MA substituted into the monomer component of a heat-polymerized acrylic resin, as follows: 0% (Control), 10%, 20% and 50% (v/v). T...

Cystic Fibrosis is a chronic disease with an extensive impact on family life. The experience of disease is the manner how individuals respond to the disease, assigning meaning meanings and searching for ways to deal with it in their daily lives. The objective of this study was to understand the experience of Cystic Fibrosis in the family context. This is an ethnographic study, performed with fa...

This study assessed folate intakes, folate concentrations in plasma and erythrocytes, plasma total homocysteine (tHcy) concentration, and urinary excretion of folate metabolites in Korean women with childbearing potential. A total of 23 women voluntarily participated in this study. Precise dietary intakes for 3 consecutive days were determined by weighing all foods consumed and folate intake wa...

Parallel Independent Component Analysis (para-ICA) is a multivariate method that can identify complex relationships between different data modalities by simultaneously performing Independent Component Analysis on each data set while finding mutual information between the two data sets. We use para-ICA to test the hypothesis that spatial sub-components of common resting state networks (RSNs) cov...

This communication reports a nanocatalyst-based electrochemical assay for proteins. Ultrasensitive detection has been achieved by signal amplification combined with noise reduction: the signal is amplified both by the catalytic reduction of p-nitrophenol to p-aminophenol by gold-nanocatalyst labels and by the chemical reduction of p-quinone imine to p-aminophenol by NaBH4; the noise is reduced ...

Pseudomonas sp. strain AP-3 grows on benzoate, phydroxybenzoate, protocatechuate, and 2-aminophenol as sole carbon and energy source. This strain converted benzoate and p-hydroxybenzoate to catechol and protocatechuate respectively, which were metabolized via the ortho-cleavage pathway. The enzymes responsible for these reactions were shown to be inducible. In contrast, strain AP-3 constitutive...
