Abstract:

This study aimed to reveal the topographic location, its measurements, and microscopic and macroscopic structures of Golden Jackal’s Lyssa by using macro anatomical and histological methods. For this study, the tongues of three dead Golden jackals were first dissected to expose the lyssa. Then, lyssa were photographed macro anatomically, and measurements were made with the FIJI® program on the photographs. Additionally, for histological examination, the samples obtained from the lyssa were stained with Masson's Trichrome stain after undergoing histological procedures. In the topograp

Abstract:

In conducting a forensic medical examination of a corpse, in cases of acute blood loss, the decisive issue for investigators is to establish the amount of lost blood. However, this often remains a difficult task, since in the absence of a suitable quantitative system for measuring the volume of blood loss, forensic medical experts have to be guided by well-known morphological signs, which can be quite subjective. In conducting a forensic medical examination of a corpse, in cases of acute blood loss, the decisive issue for investigators is to establish the amount of lost blood. Therefore, it is

Adipose tissue is an organ that performs a lot of significant physiological functions, which is why its excess in the body results in pathological states in many of its organs and systems. Adipose tissue is not only a tissue which stores fat and plays a protective role. It is an important endocrine organ where signals sent from different tissues are generated and integrated. Adipose tissue is both morphologically and physiologically differentiated. However, due to their plasticity, adipocytes can undergo a transformation and change their structure and metabolism depending on the physiological

Paratonsillar abscess (PTA) is the most common abscessing lesion. In turn, parapharyngeal abscess (PFA) is often found in patients with PTA as its complication.Aim. To study the clinical, microbiological and pathomorphological features of parapharyngeal complications in patients with PTA.Materials and methods.

В статье представлены результаты оценки влияния генотипа бычков специализированных пород на выход съедобных и несъедобных тканей туши. Целью исследования являлось изучение морфологического состава туши бычков разных генотипов в Приморском крае. Установлено, что по абсолютной массе мышечной и жировой ткани туши лидирующее положение занимали бычки герефордской породы, а по относительной массе преимущество было на стороне абердин-ангусов. Молодняк калмыцкой породы занимал промежуточное положение. Так, бычки герефордской породы превосходили сверстников калмыцкой и абердин-ангусской пород по абсолю

Inducing tissue regeneration in many skin defects, such as large traumatic wounds, burns, other physicochemical wounds, bedsores, and chronic diabetic ulcers, has become an important clinical issue in recent years. Cultured cell sheets and scaffolds containing growth factors are already in use but have yet to restore normal skin tissue structure and function. Many tissue engineering materials that focus on the regeneration process of living tissues have been developed for the more versatile and rapid initiation of treatment.

The results suggested that the bottom parenchymatous tissues experienced a perforative tear along the loading direction, while fibers continued to stretch until several fibrous tensile failure cracks were
