Gene Ex Vivo Transduction Effects on Flap Survival and MicroRNAs Expression Analysis in Rat Allotransplantation Model.

Background: The lack of noninvasive biomarkers for graft rejection remains a challenge for the accurate monitoring of vascularized composite allotransplants. Viral vector-mediated gene transfer is a promising method for preventing graft rejection. In this study, we aimed to establish the expression profile of microRNAs (miRNAs) in skin flap allotransplantation, with or without gene transfer, and determine the potential role of several miRNAs as biomarkers of acute rejection and immune tolerance.

Histochemical Identification of Motor Fascicles Using Cholinesterase Staining in Rats Using a Mixed Nerve Model.

Background: Inappropriate matching of motor and sensory fibers after nerve repair or grafting can lead to nerve recovery failure. Identifying the motor and sensory fascicles enables surgeons to match them accurately and correctly align nerve stumps, which is crucial for neural regeneration. Very few methods have been reported to differentiate between the sensory and motor nerve fascicles, and the replicability of these techniques remains unestablished.

Development of AI-Based Diagnostic Algorithm for Nasal Bone Fracture Using Deep Learning.

Facial bone fractures are relatively common, with the nasal bone the most frequently fractured facial bone. Computed tomography is the gold standard for diagnosing such fractures. Most nasal bone fractures can be treated using a closed reduction.

Histomorphometric Analysis of Femoral and Sciatic Nerve Regeneration in a Rat Hindlimb Allotransplantation Model.

Background: Peripheral nerve regeneration is essential for functional recovery after traumatic limb injury or limb transplantation. With the use of immunosuppression, it has the capacity to provide regeneration and function equal to that of an autograft. The purpose of this study was to determine whether there is any difference in regeneration and rejection response between peripheral femoral and sciatic nerve in rat hindlimb allotransplantation model.

Ossifying pilomatricoma and a novel hypothesis for its pathogenesis: A case report and comprehensive literature review.

Rationale: Pilomatricoma is a benign skin appendageal tumor derived from hair follicle matrix cells that commonly affects the head, neck, and upper extremities of the pediatric population. Since the original tumor description, diverse variants have been reported in the literature. Pilomatricoma with florid osseous metaplasia is described as an ossifying pilomatricoma and is recognized as a distinct variant of this benign tumor.

Adeno-Associated Viral Vector-Mediated Interleukin 10 Gene Transfer in Sprague-Dawley Rat Skin Allograft.

Background: Viral vector-mediated interleukin 10 gene transfer is one of the most promising methods for the prevention of graft rejection. Adeno-associated virus (AAV) is a nonpathogenic helper-dependent parvovirus. This is one of the most promising vehicles for gene delivery.

Intravascular papillary endothelial hyperplasia of the finger: a case of Masson's tumor.

Intravascular papillary endothelial hyperplasia is an uncommon benign vascular lesion characterized by a reactive proliferation of endothelial cells. The lesion of the finger often presents diagnostic challenges to surgeons because of its rarity. We report a case of intravascular papillary endothelial hyperplasia to facilitate the recognition of this uncommon lesion.

Cytosolic calcium regulates cytoplasmic accumulation of TDP-43 through Calpain-A and Importin α3.

Cytoplasmic accumulation of TDP-43 in motor neurons is the most prominent pathological feature in amyotrophic lateral sclerosis (ALS). A feedback cycle between nucleocytoplasmic transport (NCT) defect and TDP-43 aggregation was shown to contribute to accumulation of TDP-43 in the cytoplasm. However, little is known about cellular factors that can control the activity of NCT, thereby affecting TDP-43 accumulation in the cytoplasm.

Pseudocystic pilomatricoma: A new variant and review of the literature.

A classic pilomatricoma, which usually presents with an asymptomatic, solitary, firm, subcutaneous nodule in the head, neck, or extremities of the paediatric population, is easily diagnosed based on its characteristic clinical and histopathological features. However, its variants often pose particular diagnostic challenges to clinicians due to their rarity and diverse clinicopathological features. We present a new pseudocystic variant, manifesting as solid lesions floating in a fluid-filled sac.

Giant Mixed Tumor of the Skin Affecting the Hemiface.

Mixed tumor of the skin (MTS) is a rare skin adnexal neoplasm occurring in sweat glands. It is usually benign, measures 0.5 to 3 cm, and presents as a slowly growing, painless, firm nodule commonly in the head and neck regions.

Viral Vector Mediated Interleukin-10 Gene Transfer in Skin Allograft.

Background: Expression of genes with immunoregulatory capacity can potentially decrease rejection of allograft. According to recent studies, viral interleukin (IL)-10 can reduce immune response during allotransplantation and is one of the most promising methods for the prevention of rejection. Our study aimed to analyze the immunosuppressive potential of recombinant adenovirus-mediated rat IL-10 in rat skin allograft.

Validation of Animal Models for Facial Transplantation Research.

Background: The development of consistent animal experimental models is important for continued research on specific biological and immunologic aspects of vascularized composite allografts. It is also important for the translation of immune regulation and tolerance induction strategies and treatment ideas from bench to bedside. The purpose of our study is to provide an outline of the use of animal models in simulated facial transplant surgery and to investigate the feasibility of animal model use.

Effect of nonpharmacological interventions for the prevention of delirium in the intensive care unit: A systematic review and meta-analysis.

Purpose: We aimed to classify nonpharmacological interventions used for preventing delirium in the intensive care unit (ICU), and estimate their effect size.

Materials And Methods: In this systematic review and meta-analysis, the literature was searched and studies were selected based on the PRISMA flow chart. Data sources included MEDLINE, Cochrane, CINHAHL, PsyInfo, and EMBASE.

EGCG induces apoptosis in human laryngeal epidermoid carcinoma Hep2 cells via mitochondria with the release of apoptosis-inducing factor and endonuclease G.

(-)-Epigallocatechin-3-gallate (EGCG), a major green tea polyphenol, was tested for in vitro cytotoxicity against human laryngeal epidermoid carcinoma of the larynx Hep2 cells. EGCG-induced apoptotic cell death accompanied by a change in the cell cycle. However, EGCG did not result in caspase activation, nor did a caspase inhibitor block cell death.

Inhibition of apoptotic signals in overgrowth of human gingival fibroblasts by cyclosporin A treatment.

Cyclosporin A (CsA), an immunosuppressive drug, has overgrowth effects on human gingival fibroblasts (HGF) in vitro. However, the molecular mechanism responsible for the CsA-induced gingival overgrowth remains still unclear. The present study is aimed to investigate the correlation with the apoptotic signal pathway in CsA-induced overgrowth of HGF.

Involvement of both mitochondrial- and death receptor-dependent apoptotic pathways regulated by Bcl-2 family in sodium fluoride-induced apoptosis of the human gingival fibroblasts.

Sodium fluoride (NaF) has been shown to be cytotoxic and produces inflammatory responses in humans. However, the cellular mechanisms underlying the NaF-induced cytotoxicity in periodontal tissues are unclear. This study examined whether or not NaF induces apoptosis in human gingival fibroblasts (HGF), and its underlying mechanisms by monitoring various apoptosis-associated processes.

Inhibition by epigallocatechin gallate of CoCl2-induced apoptosis in rat PC12 cells.

Epigallocatechin-3-gallate (EGCG) is a major constituent of green tea polyphenols. This study was aimed to investigate the possible mechanisms of EGCG-mediated inhibition against apoptosis in rat pheochromocytoma PC12 cells by exposure to CoCl(2). Exposure to CoCl(2) caused the generation of ROS and induced cell death with appearance of apoptotic morphology and DNA fragmentation.

Effects of acupuncture on c-Fos expression in brain after noxious tooth stimulation of the rat.

Clinically, acupuncture therapy is useful for the control of acute or chronic pain. This study was designed to elucidate the antinociceptive mechanism of acupuncture and the mechanisms underlying cardiovascular reflex elicited by toothache. Expression of c-Fos, a neuronal activation marker, and the phenylethanalamine-N-methyltransferase (PNMT) were examined 1.
