The biological functions of melatonin range beyond the regulation of circadian rhythms. With regard to cancer, melatonin's potential to suppress cancer initiation, progression, angiogenesis and metastasis as well as sensitizing malignant cells to conventional chemo- and radiotherapy are among its most interesting effects. The targets at which melat...

Mesenchymal stem cells (MSCs) are mesenchymal precursors of various origins, with well-known immunomodulatory effects. Natural killer (NK) cells, the major cells of the innate immune system, are critical for the antitumor and antiviral defenses; however, in certain cases, they may be the main culprits in the pathogenesis of some NK-related conditio...

Several flexible and rigid analogs of 4H-1,2,4-triazoles (compounds 8a-g and 9a-g) bearing trimethoxyphenyl pharmacophoric unit, were designed and synthesized as potential anticancer agents. The in vitro cytotoxic assay indicated that both flexible and rigid analogs (8 and 9, respectively) can potentially inhibit the growth of cancerous cells (A549...

Tramadol (TR) is an analgesic drug used to treat moderate-to-severe pain but it induces seizure even at therapeutic doses. The exact mechanism of TR-inducing seizure is not clear but inhibition of the serotonin, GABA, and nitrous oxide (NOS) pathways are the commonly proposed mechanisms. Adenosinergic system has a crucial function in the modulation...

Melatonin is a ubiquitous indole amine that plays a fundamental role in the regulation of the biological rhythm. Disrupted circadian rhythm alters the expression of clock genes and deregulates oncogenes, which finally promote tumor development and progression. An evidence supporting this notion is the higher risk of developing malignancies among ni...

Aims: Senescence is a state ensuing aging to eliminate age-associated damage with an irreversible cell-cycle arrest mechanism, which is historically believed to be one of the tumor responses to therapy. Doxorubicin as an anti-cancer drug has been used in cancer treatment for a long time. Liposomal doxorubicin (Ldox) is a liposomal formulation of d...

A number of 1H-1,2,4-triazole alcohols containing N-(halobenzyl)piperazine carbodithioate moiety have been designed and synthesized as potent antifungal agents. In vitro bioassays against different Candida species including C. albicans, C. glabrata, C. parapsilosis, C. krusei, and C. tropicalis revealed that the N-(4-chlorobenzyl) derivative (6b) w...

Exposure to environmental toxicants (ET) results in specific organ damage and auto-immune diseases, mostly mediated by inflammatory responses. The NLRP3 inflammasome has been found to be the major initiator of the associated pathologic inflammation. It has been found that ETs can trigger all the signals required for an NLRP3-mediated response. The...

Background and purpose: Mifepristone is an oral synthetic steroid with antiglucocorticoid and antiprogesterone activities. Therefore, it could be dangerous during pregnancy since it causes cytogenetic damage and, consequently, abortion. Flavonoid compounds such as naringin have antioxidant properties and eliminate various free radicals. Naringin is...

Autophagy is a major regulatory cellular mechanism which gives the cell an ability to cope with some of the destructive events that normally occur within a metabolically living cell. This is done by maintaining the cellular homeostasis, clearance of damaged organelles and proteins and recycling necessary molecules like amino acids and fatty acids....

The aim of this study was to evaluate the role of inflammation and oxidative damage in hepatotoxicity of ethanol. Also we assessed protective effects of atorvastatin against ethanol-induced hepatotoxicity. In this study, the animals were divided into five groups: control, ethanol (10 mg/kg intraperitoneal (i.p., ethanol with atorvastatin (10, 20 mg...

Gastric cancer (GC) is a predominant malignancy with a high mortality rate affecting a large population worldwide. The etiology of GC is multifactorial spanning from various genetic determinants to different environmental causes. Current tretaments of GC are not efficient enough and require improvements to minimize the adverse effects. Melatonin, a...

Objective(s) Hyperglycemia promotes oxidative stress that plays a crucial role in the pathogenesis of Diabetic nephropathy (DN). In this study, we investigated the synergism effects of hydroalcoholic extract of Urtica dioica and pioglitazone (PIO) on the prevention of DN in streptozotocin induced-diabetic mice. Materials and Methods Forty-two mice...

Acrylamide (AA) is an important industrial chemical agent that is mainly used in the production of polymers and copolymers. Recently it has been attention because of its production in the diet at high-temperature (>120 ºC) processes such as cooking, frying, toasting, roasting or baking of high carbohydrate foods. According to high exposure to acryl...

Alhagi species are well known in Iran (locally known as Khar Shotor) and other parts of Asia as a popular folk medicine. Recent research has shown extensive pharmacological effects of these species. This paper is a comprehensive review of the phytopharmacological effects and traditional uses of Alhagi species and their active constituents with spec...

Objective The liver flukes, Fasciola spp. and Dicrocoelium dendriticum, infect ruminants and other mammalian extensively and cause major diseases of livestock that produce considerable economic losses. Methods A survey of 2391 sheep and goats slaughtered at an abattoir in Amol region, northern Iran was used to determine the prevalence of the liver...

Hydatidosis is one of the zoonotic diseases with special importance for public health and causing financial problems in developed and developing countries. This infection is the most prevalent disease in the Middle East especially in Iran. In this survey, internal organs of 1,200 sheep and 1,200 goats, including liver, lung, heart, and kidney, were...
