Modulation of the Immune System Mechanisms using Probiotic Bacteria in Allergic Diseases: Focus on Allergic Retinitis and Food Allergies.

Allergic illnesses occur when an organism's immune system is excessively responsive to certain antigens, such as those that are presented in the environment. Some people suffer from a wide range of immune system-related illnesses including allergic rhinitis, asthma, food allergies, hay fever, and even anaphylaxis. Immunotherapy and medications are frequently used to treat allergic disorders.

Revisiting Inhibition Effects of miR-28 as a Metastasis Suppressor in Gastrointestinal Cancers.

MicroRNAs are critical epigenetic regulators that can be used as diagnostic, prognostic, and therapeutic biomarkers for the treatment of various diseases, including gastrointestinal cancers, among a variety of cellular and molecular biomarkers. MiRNAs have also shown oncogenic or tumor suppressor roles in tumor tissue and other cell types. Studies showed that the dysregulation of miR-28 is involved in cell growth and metastasis of gastrointestinal cancers.

Anti-proliferative activity of Artemisia marschalliana on cancerous cell lines.

Background: The genus Artemisia of the Asteraceae family has different species that are used in the treatment of a wide range of diseases, including cancers due to the presence of valuable compounds and important medicinal properties. Various studies on the anti-tumor effect of different species of Artemisia have proven the cytotoxic properties of these plants in cancer treatment, and several anti-cancer compounds of this genus have been purified.

Objective: The objective of this study was to investigate the cytotoxicity and related mortality mechanisms of Artemisia marschalliana essential oil and extracts.

Pharmacological effects and therapeutic potential of natural compounds in neuropsychiatric disorders: An update.

Neuropsychiatric diseases are a group of disorders that cause significant morbidity and disability. The symptoms of psychiatric disorders include anxiety, depression, eating disorders, autism spectrum disorders (ASD), attention-deficit/hyperactivity disorder, and conduct disorder. Various medicinal plants are frequently used as therapeutics in traditional medicine in different parts of the world.

Curcumin-Loaded Silica Nanoparticles: Applications in Infectious Disease and Food Industry.

Curcumin has multiple properties that are used to cure different diseases such as cancer, infections, inflammatory, arthritic disease, etc. Despite having many effects, the inherent physicochemical properties-such as poor water solubility, chemical instability, low bioavailability, photodegradation, fast metabolism, and short half-life-of curcumin's derivatives have limited its medical importance. Recently, unprecedented advances in biomedical nanotechnology have led to the development of nanomaterial-based drug delivery systems in the treatment of diseases and diagnostic goals that simultaneously enhance therapeutic outcomes and avoid side effects.

Potential mechanisms of quercetin in cancer prevention: focus on cellular and molecular targets.

Over the past few years, the cancer-related disease has had a high mortality rate and incidence worldwide, despite clinical advances in cancer treatment. The drugs used for cancer therapy, have high side effects in addition to the high cost. Subsequently, to reduce these side effects, many studies have suggested the use of natural bioactive compounds.

Evaluation of anti-proliferative activity of Eryngium caucasicum on melanoma cancer cells.

Background: The genus Eryngium is a member of the Apiaceae family that has shown different pharmacological effects mainly including anti-inflammatory, analgesic, anti-cancer, hepatoprotective, and anti-oxidant. Previous research on the anti-cancer activity of Eryngium in some cancer cell lines has led us to explore the anti-proliferative activity of E. caucasicum in the B16F10 cell line.

Prognostic Value and Biological Role of miR-126 in Breast Cancer.

In eukaryotic organisms such as humans, some noncoding single-stranded RNAs (ncRNAs) contribute to regulating the expression of some genes before and after the transcription process, which in turn controls a number of vital physiological processes, including cell proliferation, differentiation, invasion, angiogenesis, and embryonic development. miR-126 is one of these miRNAs expressed exclusively in endothelial cells such as capillaries and vessels involved in controlling angiogenesis. In recent years, the link between miRs such as miR-126 and the pathology of breast cancer has attracted the attention of many researchers.

Curcumin nanoformulations: Beneficial nanomedicine against cancer.

Curcumin is a phytochemical achieved from the plant turmeric. It is extensively utilized for the treatment of several types of diseases such as cancers. Nevertheless, its efficiency has been limited because of rapid metabolism, low bioavailability, poor water solubility, and systemic elimination.

Application of Collagen and Mesenchymal Stem Cells in Regenerative Dentistry.

Collagen is an important macromolecule of Extracellular Matrix (ECM) in bones, teeth, and temporomandibular joints. Mesenchymal Stem Cells (MSCs) interact with the components of the ECM such as collagen, proteoglycans, Glycosaminoglycans (GAGs), and several proteins on behalf of variable matrix elasticity and bioactive cues. Synthetic collagen-based biomaterials could be effective scaffolds for regenerative dentistry applications due to mimicking of host tissues' ECM.

Quercetin as a Novel Therapeutic Approach for Lymphoma.

Lymphoma is a name for malignant diseases of the lymphatic system including Hodgkin's lymphoma and non-Hodgkin's lymphoma. Although several approaches are used for the treatment of these diseases, some of them are not successful and have serious adverse effects. Therefore, other effective treatment methods might be interesting.

sp. nov., a moderately halophilic bacterium isolated from Urmia Lake in Iran.

In the course of screening halophilic bacteria in Urmia Lake in Iran, which is being threatened by dryness, a novel Gram-negative, moderately halophilic, heterotrophic and short rod-shaped bacteria was isolated and characterized. The bacterium was isolated from a water specimen and designated as TBZ3. Colonies were found to be creamy yellow, with catalase- and oxidase-positive activities.

Halomonas tabrizica sp. nov., a novel moderately halophilic bacterium isolated from Urmia Lake in Iran.

A novel moderately halophilic, Gram-stain negative and aerobic bacterium, designated strain TBZ21, was isolated from a water sample of Urmia Lake, Iran. Cells were observed to be non-motile rods with no flagellum, showing positive catalase and oxidase reactions. Strain TBZ21 was found to grow at 10-40 °C (optimum, 30 °C), at pH 7-10 (optimum, pH 8) and in the presence of 1-22% (optimum, 10%).

Isolation and characterization of halophilic bacteria from Urmia Lake in Iran.

Urmia Lake is one of the most permanent hypersaline lakes in the world which is threatened by hypersalinity and serious dryness. In spite of its importance no paper has been published regarding bacterial community of this lake. Accordingly, the present study aimed to investigate the halophilic bacteria in the aforementioned lake.
