Sulforaphane protects against LPS-induced liver injury in mice by antagonizing oxidative stress and apoptosis through AMPK activation.

Objectives: Given the adverse effect of liver injury on a multitude of body functions, it is vital to understand its underlying mechanism and how to overcome it. In this study, lipopolysaccharide (LPS) was used to induce liver injury, while sulforaphane (SFN), a natural phytochemical, was used as the antagonist to overcome the deleterious effect.

Methods: Twenty-four mice were divided into three groups: Control group (0.

A new cirrhotic animal protocol combining carbon tetrachloride with methotrexate to address limitations of the currently used chemical-induced models.

Chemically induced cirrhotic animal models are commonly used. However, they have limitations such as high mortalities and low yield of cirrhotic animals that limit their uses. To overcome limitations of the chemically induced cirrhotic animal model via combined administration of methotrexate (MTX) with CCl and decrease their commonly used doses depending on the proposed synergetic cirrhotic effect.

Pharmacological Studies on the Antidiabetic, Antioxidant, and Antimicrobial Efficacies of Resin in Streptozotocin-Induced Diabetes in Rats: A Preclinical Study.

Results: The aqueous extracts of MAE were phytochemically analyzed, and the results revealed the presence of high concentrations of tannins, sterols, and isoprenoids (terpenoids), while steroids and flavonoids were found in moderate concentrations. The plant extract showed promising inhibition of the growth of gram-positive and gram-negative pathogens. It also showed that MAE has potential antihyperglycemic and antioxidant activities.

Protective Effect of Vitamin D against Hepatic Molecular Apoptosis Caused by a High-Fat Diet in Rats.

The protective effects of vitamin D (VitD) in different diseases were studied. The liver is of great interest, especially with the presence of VitD receptors. A high-fat diet (HFD) is associated with many diseases, including liver injury.

A High Dose, Not Low Dose, of Vitamin D Ameliorates Insulin Resistance in Saudi Women.

Vitamin D has been traditionally seen to be mainly involved in the regulation of bone homeostasis. However, vitamin D has also been clinically linked to various diseases, including metabolic syndrome. The aim of this study was to examine the effect of low and high doses of a vitamin D supplement on the serum levels of 25(OH)D3 and insulin resistance.

A Single Vitamin D Bolus Supplementation Improves Vitamin D Status and Reduces Proinflammatory Cytokines in Healthy Females.

Vitamin D deficiency is a global health problem that not only leads to metabolic bone disease but also to many other illnesses, most of which are associated with chronic inflammation. Thus, our aim was to investigate the safety and effectiveness of a single high dose of vitamin D (80,000 IU) on vitamin D status and proinflammatory cytokines such as interleukin (IL)6, IL8 and tumor necrosis factor (TNF) in healthy Saudi females. Fifty healthy females were recruited and orally supplemented with a single vitamin D bolus (80,000 IU).

A Single Oral Vitamin D Bolus Reduces Inflammatory Markers in Healthy Saudi Males.

Vitamin D deficiency has increased in the general population and is a public health issue. Vitamin D plays an important role in regulating the immune system, e.g.

Studying the Anticancer Effects of Thymoquinone on Breast Cancer Cells through Natural Killer Cell Activity.

Cancer immunotherapy is quickly growing and can now be viewed as the "fifth column" of cancer treatment. In addition, cancer immunotherapy has shown promising results with different kinds of cancers and may be used as a complementary therapy with various types of treatments. Thus, "immuno-oncology" is showing astounding advantages.

Genetic Association between Different Metabolic Variants in and in Type 2 Diabetes Mellitus among the Western Saudi Population: Case-Control Study.

Type 2 diabetes mellitus (T2DM) is a multifactorial disease with a high global incidence. Hypertriglyceridemia is a major risk factor for both cardiovascular disease and T2DM. In this study, we determined the allele and genotype frequencies of apolipoprotein A5 () single nucleotide polymorphism (SNP) rs662799 and perilipin 1 () SNPs rs894160, rs6496589, and rs1052700 and evaluated their association with T2DM risk in western Saudis.

The role of human mast cells in allergy and asthma.

Mast cells are tissue-inhabiting cells that play an important role in inflammatory diseases of the airway tract. Mast cells arise in the bone marrow as progenitor cells and complete their differentiation in tissues exposed to the external environment, such as the skin and respiratory tract, and are among the first to respond to bacterial and parasitic infections. Mast cells express a variety of receptors that enable them to respond to a wide range of stimulants, including the high-affinity FcεRI receptor.

Heat Transfer in Biological Spherical Tissues during Hyperthermia of Magnetoma.

Hyperthermia therapy is now being used to treat cancer. However, understanding the pattern of temperature increase in biological tissues during hyperthermia treatment is essential. In recent years, many physicians and engineers have studied the use of computational and mathematical models of heat transfer in biological systems.

Modulated Electrohyperthermia: A New Hope for Cancer Patients.

According to the World Health Organization, the prevalence of cancer has increased worldwide. Oncological hyperthermia is a group of methods that overheat the malignant tissues locally or systematically. Nevertheless, hyperthermia is not widely accepted, primarily because of the lack of selectivity for cancer cells and because the temperature-triggered higher blood flow increases the nutrient supply to the tumor, raising the risk of metastases.

The BMP antagonist Noggin is produced by osteoblasts in response to the presence of prostate cancer cells.

Bone metastasis is a key event responsible for morbidity in prostate cancer patients. Interactions between prostate cancer cells and the bone microenvironment facilitate survival of tumor cells and alter bone turnover, a process that is thought to enhance the growth of metastases in this site. This study aimed to test the hypothesis that the presence of tumors cells increases transforming growth factor beta (TGF-β) signaling in bone and that this regulates the proliferation and differentiation of osteoblastic lineage cells in metastatic sites.
