A Rapid Strategy for the Isolation of New Faustoviruses from Environmental Samples Using Vermamoeba vermiformis

A Rapid Strategy for the Isolation of New Faustoviruses from Environmental Samples Using Vermamoeba vermiformis

We describe here the latest advances in viral isolation for the characterization of new genotypes of Faustovirus, a new asfarvirus-related lineage of giant viruses. This protocol can be applied to the high throughput isolation of viruses, especially giant viruses infecting amoeba.

Direct Microbial Identification using An Automated Microbial Identification System to Facilitate the EUCAST RAST Method Without Mass Spectrometry

Direct Microbial Identification using An Automated Microbial Identification System to Facilitate the EUCAST RAST Method Without Mass Spectrometry

EUCAST has developed a direct antimicrobial susceptibility testing (AST) protocol for automated blood cultures. However, its dependence on mass spectrometry-based microbial identification can be obviated by using a direct inoculum preparation protocol in an automated microbial identification system. This approach can provide AST reports within 24 h of sample...

Protocol for Developing a Femur Osteotomy Model in Wistar Albino Rats

Protocol for Developing a Femur Osteotomy Model in Wistar Albino Rats

Here, we present a protocol to iatrogenically fracture the shaft of the femur of Wistar albino rats and follow up on the development of the callus. This femur osteotomy model can help researchers evaluate the process of fracture healing and to study how a drug could influence fracture healing.

Symptom Assessment of Patients with Allergic Rhinitis Using an Allergen Exposure Chamber

Symptom Assessment of Patients with Allergic Rhinitis Using an Allergen Exposure Chamber

A protocol for conducting a challenge in an allergen exposure chamber (AEC) facility is presented. AECs have proven to be safe and effective tools for the induction of allergic symptoms or as an endpoint in the efficacy testing of allergen immunotherapy due to their ability to maintain stable particle concentrations and environmental...

Obtaining Human Microglia from Adult Human Brain Tissue

Obtaining Human Microglia from Adult Human Brain Tissue

This protocol is an efficient, cost effective and robust method of isolating primary microglia from live, adult, human brain tissue. Isolated primary human microglia can serve as a tool for studying cellular processes in homeostasis and disease.

Area of Science:

Physical Chemistry
Solution Chemistry
Chemical Thermodynamics

Background:

Raoult's law (1887) approximates solute and solvent behavior in mixtures, exact for ideal solutions.
Deviations from Raoult's law are observed in non-ideal solutions.
Callendar's extension (1908) proposed hydrated water to explain some deviations.

Purpose of the Study:

To demonstrate that incorporating water hydration equilibria validates Raoult's law and Callendar's extension across all concentrations.
To elucidate the interactions between water and solutes in solution.
To provide a more accurate model for highly concentrated solutions.

Main Methods:

Modeling solution behavior by assuming equilibria between free water and its hydrated forms.
Applying this model to analyze deviations from conventional Raoult's law.
Investigating solute-water interactions within the solution framework.

Main Results:

The proposed model, incorporating water hydration equilibria, validates Raoult's law and Callendar's extension over the entire concentration range.
The model successfully explains departures from Raoult's law observed in real solutions.
It provides a clear picture of water and solute interactions in solution.

Conclusions:

A revised understanding of Raoult's law, accounting for water hydration, is crucial for accurately describing solution behavior.
This model has significant implications for understanding atmospheric aerosols, climate change, air quality, and industrial processes involving concentrated solutions.
