INTRODUCTION: The following article is an indepth comparison of the formaldehyde and glutaraldehyde chemical reactivities and nuances of reaction with predominately proteins and some other related chemicals and body tissues that are of importance to embalming. The comparisons are enlightening for the similarities and the vast differences between these two reactive aldehydes in protein fixation modalities. Also covered as an important topic of discussion and use is the relative disinfection and… 
EMBALMING FLUID - MODIFIED COMPOSITION FOR HOT AND HUMID PLACES
TLDR
It was concluded that the composition of the embalming fluid should be modified according to the climate of the place and antifungal agents must be added in the solution in the hot and humid places.
Human body preservation – old and new techniques
TLDR
This review contains a brief historical review of the history of embalming, starting with ancient cultures such as the Egyptians and the lesser known Chinchorro culture, then going down the centuries and describing the anatomical techniques developed over the last two centuries.
Effects of different cadaver preservation methods on muscles and tendons: a morphometric, biomechanical and histological study
TLDR
Thiel and SSS fixed cadavers are more suitable for purposes as surgical trainings and development of new surgical procedures, but the change in the micro-anatomical structure of the muscles, especially with the Masson’s trichrome staining, caused by these two solutions should not be overlooked.
Comparison of DNA yield and STR success rates from different tissues in embalmed bodies
TLDR
Results indicate that soft tissues affected by lividity may experience greater exposure to formalin, resulting in more DNA damage and reduced downstream STR success than tissues under compression, and recommend harvesting from selected muscles or fingernails for human identification purposes.

Vaccine Technologies and Platforms for Infectious Diseases: Current Progress, Challenges, and Opportunities
TLDR
Recent advances in vaccine technologies and platforms are summarized focusing on their mechanisms of action, advantages, and possible drawbacks.
Comparison of qualitative and quantitative alterations caused by use of various fixatives in the myocardium
TLDR
It was determined that a newly developed enriched saline solution and low concentration formaldehyde solution can be used safely for the preparation, preserve and long term use of educational materials.

The reaction of formaldehyde with unsaturated fatty acids during histological fixation
TLDR
The occurrence of these adducts in tissues explains why it is that less lipid can be demonstrated histologically in material that has been stored in form-aldehyde for a considerable length of time.
On the chemistry of formaldehyde fixation and its effects on immunohistochemical reactions
TLDR
The superiority of methacarn, alcohol or acetone over formaldehyde fixation for immunohistochemical demonstration of prekeratin, myosin, type I and type IV collagen, laminin and fibronectin can be ascribed to the irreversible alterations of tissue proteins by formaldehyde.

TLDR
Using this fixative and the peroxidase-labeled antibody technique, basement membrane antigen was localized within the cisternae of endoplasmic reticulum of parietal yolk sac cells and in extracellular basement membranes with adequate tissue preservation, a task which has not been successfully accomplished by conventional fixatives.
The effects of mercaptoethanol-formaldehyde on tissue fixation and protein retention
TLDR
It is demonstrated that mercaptoethanol-formaldehyde fixed and cross-linked tissues better than formaldehyde at 3 h and 4 h, but not at 1 h and 2 h, and the most effective concentration of mercapteethanol for tissue fixation in 4% formaldehyde is 0.0025%.
The efficiency of aldehyde fixation for electron microscopy: Stabilization of rat brain tissue to withstand osmotic stress
TLDR
Rat brains were fixed either with glutaraldehyde (GA) or formaldehyde (FA) and Ultrastructural preservation was good after only 20 min GA-fixation, provided that the subsequent treatment was with isotonic solutions.
Tissue fixation with phenol—formaldehyde for routine histopathology
TLDR
Histopathological material fixed in buffered phenol—formaldehyde and rapidly advanced to paraffin in an enclosed tissue-processor showed improved nuclear and cytoplasmic detail, reduced shrinkage and distortion, and an absence of formalin pigment.
Effect of formalin tissue fixation and processing on immunohistochemistry.
TLDR
If consistently applied, these procedures could eliminate some of the sources of variation in immunohistochemical stains and help to achieve standardization of fixation and processing.

TLDR
It is concluded that the cross-linking of proteins that occurs in the process of formaldehyde fixation "locks in" the secondary structure of these protein molecules.
Disinfection, Sterilization and Preservation
TLDR
When reading has become a habit, you will not make it as disturbing activities or as boring activity, and you can gain many benefits and importances of reading.
