Studies have shown that nitric oxide (NO) promotes re-epithelialization and stimulates angiogenesis and neovascularization. This study aimed to investigate the effect of exogenous NO on diabetic wound healing.

Transplantation of human umbilical cord mesenchymal stem cells optimized with IFN-γ is a potential procedure for modification of motor impairment in multiple sclerosis cases: a preclinical systematic review and meta-analysis study.

Stem cells transplantation (SCT) is known as a newfound strategy for multiple sclerosis (MS) treatment. Human umbilical cord mesenchymal stem cells (hUCMSCs) contain various regenerative features. Experimental autoimmune encephalomyelitis (EAE) is a laboratory model of MS.

Terminalia chebula attenuates restraint stress-induced memory impairment and synaptic loss in the dentate gyrus of the hippocampus and the basolateral and central nuclei of the amygdala by inhibiting oxidative damage.

Chronic restraint stress induces cognitive abnormalities through changes in synapses and oxidant levels in the amygdala and hippocampus. Given the neuroprotective effects of fruit of Terminalia chebula (Halileh) in different experimental models, the present investigation aimed to address whether Terminalia chebula is able to reduce chronic restraint stress-induced behavioral, synaptic and oxidant markers in the rat model. Thirty-two male Wistar rats were randomly divided into four groups as follows: control (did not receive any treatment and were not exposed to stress), stress (restraint stress for 2 h a day for 14 consecutive days), Terminalia chebula (received 200 mg/kg hydroalcoholic extract of Terminalia chebula), and stress + Terminalia chebula groups (received 200 mg/kg extract of Terminalia chebula twenty minutes before stress) (n = 8 in each group).

The Effects of Mesenchymal Stem Cells Loaded with Oncolytic on Mouse Models of Colorectal Cancer.

Background: Cancer is a major cause of death worldwide. Colorectal cancer is the second most common type. Additional treatments like chemotherapy and radiation therapy may be recommended.

Anti-metastatic effect of taraxasterol on prostate cancer cell lines.

Background And Purpose: Prostate cancer is the second cause of death among men. Nowadays, treating various cancers with medicinal plants is more common than other therapeutic agents due to their minor side effects. This study aimed to evaluate the effect of taraxasterol on the prostate cancer cell line.

Antiproliferative effects of mesenchymal stem cells carrying Newcastle disease virus and Lactobacillus Casei extract on CT26 Cell line: synergistic effects in cancer therapy.

Background And Aims: Colorectal Cancer (CRC) is a frequent malignancy with a high mortality rate. Specific inherited and environmental influences can affect CRC. Oncolytic viruses and bacteria in treating CRC are one of the innovative therapeutic options.

Effect of Calcitriol Treated Mesenchymal Stem Cells as an Immunomodulation Micro-environment on Allergic Asthma in a Mouse Model.

Background: Allergic asthma is a chronic inflammatory illness of the respiratory system characterized by an increase in the number of inflammatory cells in the airways and trouble breathing. Mesenchymal stem cells (MSCs) have the potential to be used in inflammatory diseases as a cellular immunosuppressive treatment. They express calcitriol receptors and communicate with other immunocytes, which increases their anti-inflammatory activity.

Cell therapy procedure using anti-inflammatory macrophage M2 can potentially reduce Clinical Score in animals with Experimental Autoimmune Encephalomyelitis: A preclinical systematic review and meta-analysis study.

Macrophage M2 (MP2)-based cell therapy is a novel medicinal treatment for animals with Experimental Autoimmune Encephalomyelitis (EAE) as an experimental model of multiple sclerosis (MS). This systematic review and meta-analysis study was designed to assess the overall therapeutic effects of MP2 cell therapy on Clinical Score and motor impairment in EAE-induced animals. All experiments on MP2 cell therapy in animals with EAE were gathered (by October 2, 2022) from English (PubMed, Scopus, WoS, Science Direct, and ISC) and Persian (MagIran and SID) databases.

Comprehensive Assessment of Multiple Sclerosis: From Immunotherapy and Immunopathogenesis to Predictive Biomarkers.

Background & Objective: Multiple sclerosis (MS) is an inflammatory neurological disorder that affects the central nervous system (CNS) and causes individuals to experience a variety of cognitive and physical problems. As proven by two decades of clinical experience with immunomodulatory therapies for MS, the disease progresses and relapses through several immunological pathways. New medicines aimed at remyelination and neurodegeneration are being developed; however, they need stronger evidence before being introduced into routine clinical care.

Oncolytic Viruses and Cancer, Do You Know the Main Mechanism?

The global rate of cancer has increased in recent years, and cancer is still a threat to human health. Recent developments in cancer treatment have yielded the understanding that viruses have a high potential in cancer treatment. Using oncolytic viruses (OVs) is a promising approach in the treatment of malignant tumors.

Stem cell therapy as a recent advanced approach in male infertility.

Infertility is one of the most common problems in the world that has negative effects on society and infertile people. Among the various causes of infertility, male infertility accounts for almost half of all infertility cases. Despite advances in medicine, current male infertility treatments such as assisted reproductive technology (ART) have not been successful in treating all types of male infertility.

Anti-proliferative and apoptotic effects of hull-less pumpkin extract on human papillary thyroid carcinoma cell line.

Papillary thyroid carcinoma (PTC) is one of the most common cancers of the endocrine system. Previous studies have shown that the extract of hull-less pumpkin seed (HLPS) has a significant anti-cancer effect. The aim of this study was to evaluate the effect of this plant extract on the proliferation of PTC cells.

Therapeutic Potential of Nanoparticle-loaded Hydroxyurea on Proliferation of Human Breast Adenocarcinoma Cell Line.

Although Hydroxyurea is one of the most widely used drugs in treating breast cancer, the use of it leads to some side effects. Hence, in order to reduce complications of treatment and increase its efficiency, drug delivery has been attracted more attention. Present study included three stages.

Evaluation of the protective and therapeutic effects of gum aqueous extract on cellular and pathological aspects of experimental asthma in Balb/c mice.

Objective: The purpose of this study was to investigate the protective and therapeutic effects of aqueous extract of gum on an experimental asthma in BALB/c mice.

Materials And Methods: Aqueous extract of dried and milled gum was assemble and evaluate by GC-MS. In order to investigate the effect of gum extract on cellular and pathological aspects of asthma, 60 BALB/c mice were divided into six groups as: negative control, asthmatic group, asthmatic group receiving dexamethasone (1mg/kg; intraperitoneal (IP)) and three asthmatic groups receiving different concentrations of the extract (100, 200 and 400 mg/kg, orally) from the beginning of the study and continued for 84 days.

A Rare Case of Takayasu's Arteritis with Aortic Arch Branching Pattern Variation in a Young Female.
