Leukemia inhibitory factor (LIF) is a multi-functional cytokine secreted from cells such as lymphocytes and hepatocytes. This study aimed to evaluate the effect of LIF on natural killer group 2 member D (NKG2D) receptors' expression and presentation on natural killer (NK) cells. For this purpose, peripheral blood mononuclear cells taken from 4 young male healthy blood donors were isolated and the effect of LIF (25 ng/mL) after 12, 24, and 48 hours of incubation, on NKG2D receptors expression and presentation was investigated using flow cytometry and real-time-polymerase chain reaction (PCR).

In addition, we attempted to clarify whether the immune system is involved in this activity. Initially, the LD of the venoms from these scorpions were determined and their 0.
View Article and Find Full Text PDFTumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a promising anticancer cytokine with minimal toxicity towards normal cells. Nevertheless, most primary cancers are often intrinsically TRAIL-resistant or can acquire resistance after TRAIL therapy. This study aimed to investigate the inhibitory effect of co-treatment of 3-bromopyruvate (3-BP) as a potent anticancer agent with TRAIL on colon cancer cells (HT-29).

Crocin or pantoprazole was administered to rats 30 min before indomethacin. Five hours later, the animals were killed and their stomachs were removed and examined macroscopically.

The aim of the present in vivo study was to identify the optimal effective dose, the most favorable time and the route of administration of the available polyvalent scorpion antivenom against the toxic effects induced by Hemiscorpius lepturus (H. lepturus) venom in rat. The end point for assessment included measurement of alanin-amino-peptidase (AAP) and N-acetyl-b-d-glucosaminidase (NAG), biochemical urine analysis and histopathological assessment.

Objectives: The objective of this randomized clinical trial was to evaluate the effectiveness of topical shallomin alcoholic solution in treatment of cold sore.
Patients And Methods: A total of 60 volunteers who met the inclusion criteria were randomly allocated to two equal groups to hourly apply topical of either 0.
Hemiscorpius lepturus (H. lepturus), one of the most venomous scorpions in tropical and sub-tropical areas, belongs to the Hemiscorpiidae family. Studies of antibodies in sera against the protein component of the venom from this organism can be of great use for the development of engineered variants of proteins for eventual use in the diagnosis/treatment of, and prevention of reactions to, stings.

Background: Hemolyis of red blood cells is a serious toxic effect commonly found among patients envenomed by Hemiscorpius lepturus scorpion.
Objectives: The aim of the present study was to evlaute the efficay of the avaible polyvalent antivneom in preventing this phenomena.
Materials And Methods: Using a red blood cell fragility test, the anti-hemolytic effectiveness of a new antivenom serum against Hemiscorpius lepturus venom was investigated.
Background: Previous studies have shown that shallomin, one of the active constituents of Persian shallot, has a broad range of antimicrobial properties.
Objectives: The safety of shallomin must be established before it can be used in clinical applications. Therefore, the aim of the present study was to evaluate the acute toxic effects of shallomin and to estimate its lethal dose low (LDLo) value.
Objectives: THE AIM OF THE PRESENT STUDY WAS TO COMPARE THE THERAPEUTIC INDICES OF SEVERAL AGENTS USED IN TREATMENT OF INFLAMMATORY CONDITIONS WHICH INCLUDED: Vitamin E, hydro-alcoholic extracts of Glycyrrhiza glabra, Matricaria aurea, dexamethasone, piroxicam and diclofenac using Wehi-164 fibrosarcoma cells.
Materials And Methods: Cytotoxicity evaluation was based on vital dye exclusion assay. Matrix-metalloproteinases inhibition (MMPI) was assessed by gelatinase zymography method.
