2.1. Obtention of the Oregano Essential Oil and Fractions. The diagram of the process of obtaining oregano essential oil (Ooil) through the steam entrainment method and the oil fractions through a fractional distillation system is shown in Figure 1.The first fraction started to distill at a temperature of 82 C and the last fraction distilling at 140 C, finally undistilled oil was obtained.

Pathogen Associated Molecular Pattern - an overview

Jungo Kato, Camilla I. Svensson, in Progress in Molecular Biology and Translational Science, 2015. 1 Introduction. Pathogen-associated molecular pattern molecules (PAMPs), for example, lipopolysaccharide (LPS), are a diverse set of microbial molecules that share a nuer of different general “patterns,” or structures, that alert immune cells to destroy intruding pathogens. 1,2 It …

Distillation Column - an overview | ScienceDirect Topics

Distillation columns are key unit operations in traditional chemical engineering, especially in the oil and gas industry. They are usually tall structures filled with heated flammable fluids, and are consequently inherently hazardous. Many serious accidents have centered on columns and their ancillary operations.

Fractional Distillation - Detailed Explanation Along With …

2022-4-12 · Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

Damage-Associated Molecular Patterns in Inflammatory

Damage-associated molecular patterns (DAMPs) are endogenous danger molecules that are released from damaged or dying cells and activate the innate immune system by interacting with pattern recognition receptors (PRRs). Although DAMPs contribute to the host''s defense, they promote pathological inflammatory responses.
