AIM To evaluate the effect of thymoquinone on the healing of experimental left colon anastomosis in rats. METHODS Forty Wistar albino rats weighing 250-300 g were randomly divided into four groups (10 rats/group). Group 1 (control group) rats were not administered Thymoquinone (TQ) for 3 days after the operation. Group 2 was administered daily TQ for 3 days starting from the first day after t...

Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psammomatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors i...

Introduction: Electromagnetic radiofrequency (RF) sources are widely used to heat up cutaneous and subcutaneous tissues for different applications, such as, generation of new dermal collagen and denaturation of adipocytes or fat cells. The subcutaneous morphology of tissue consists of a fine, collagenous and fibrous septa network enveloping clusters of adipocyte cells [1]; however, it is common...

Atherosclerotic plaque rupture occurs when mechanical loading exceeds its material strength. Mechanical analysis has been shown to be complementary to the morphology and composition for assessing vulnerability. However, strength and stretch thresholds for mechanics-based assessment are currently lacking. This study aims to quantify the ultimate material strength and extreme extensibility of ath...

During the initial period following immersion of parenchymatous cells of liver, kidney, or pancreas in various fluids immediately after their removal from the body water exchange is like that which occurs when water passes by osmosis through a semipermeable membrane; intake of water is proportional to the square root of the elapsed time and when liver tissue is immersed in solutions of sodium c...

Malignant phyllodes tumor is usually diagnosed by the presence of benign duct-like epithelium and malignant mesenchymal tissue. In addition to the usual fibrosarcomatous features, the mesenchymal component may show areas resembling osteogenic sarcoma, chondrosarcoma, liposarcoma, leiomyosarcoma, rhabdomyosarcoma, malignant mesenchymoma, and, very rarely, malignant fibrous histiocytoma. We prese...

Hamartoma of the esophagus is a rare lesion and the number of cases reported in the literature to date is limited. The majority of hamartomas are intraluminal tumors located in the upper third of the esophagus. Histopathologically, the majority of these tumors comprise a mixture of adipose tissue, skeletal/smooth muscle tissue, vascular components and fibrous connective tissue. We herein presen...

normal bone marrow is replaced with fibro-osseous tissue. Patients are often asymptomatic, and fibrous dysplasia is often detected incidentally in patients with malignancy in whom F-fluoro-2deoxy-glucose positron emission tomography (F -FDG PET/ CT) is performed for metastatic disease. PET/CT findings of fibrous dysplasia have been reported on several papers. The level of FDG uptake in fibrous ...

This study systematically investigates the role of graphene oxide (GO) and reduced GO (rGO)/silk-based composite micro/nano-fibrous scaffolds in regulating neuronal cell behavior vitro, given limited comparative studies on effects family materials nerve regeneration. Fibrous can mimic architecture native extracellular matrix are potential candidates for tissue engineering peripheral nerves. Sil...

Electrospinning allows the production of fibrous networks for tissue engineering, drug delivery, and wound healing in health care. It enables the production of constructs with large surface area and a fibrous morphology that closely resembles the extracellular matrix of many tissues. A fibrous structure not only promotes cell attachment and tissue formation but could also lead to very interesti...
