Effect of sodium chloride on efficiency of cisplatinum dissolved in dimethyl sulfoxide: an in vitro study.

Cisplatinum (Cispt) is an anti-cancer drug with a low level of solubility. One of Cispt's solvents is dimethyl sulfoxide (DMSO) which can be substituted with chlorine of drug as Cispt's solvent. Applying such a solvent in biological studies is impossible due to intense reduction in activity.

Archaeosome: as new drug carrier for delivery of Paclitaxel to breast cancer.

In the present study, paclitaxel was archaeosomed to reduce side effects and improve its therapeutic index. Carriers have made a big evolution in treatment of many diseases in recent years. Lipid carriers are of special importance among carriers.

Effect of bracket bonding with Er: YAG laser on nanomechanical properties of enamel.

Background: The aim of this study was to compare the effects of conventional acid etching and laser etching on the nano-mechanical properties of the dental enamel using nano-indentation test.

Protease in sturgeon sperm and the effects of protease inhibitors on sperm motility and velocity.

In mammals, proteases are present in sperm acrosome and play key role in fertilization. Sturgeon sperm has an acrosome, but its physiology, biochemistry, and potential role in fertilization are unknown. In the present study, we have observed high protease activity in acidic extract of intact sperm compared to that of seminal plasma in sterlet (Acipenser ruthenus).

Paraneoplastic neurologic syndromes in children: a review article.

Paraneoplastic neurological syndromes (PNS) were initially defined as neurological syndromes with unknown etiology that often associate with cancer. This broad definition may lead to misconception that any neurological syndrome, which coincides with a cancer might be considered as PNS. In the last two decades it has been suggested that PNSs are mainly immune-mediated.

Overview Of Literature: There was controversy about surgical techniques including anterior, posterior, or a combined anterior-posterior approaches are applied to treat non-congenital scoliosis with surgical indications.

Biochemical and hemato-immunological parameters in juvenile beluga (Huso huso) following the diet supplemented with nettle (Urtica dioica).

The present study investigated the effects of different dietary nettle (Urtica dioica) levels on biochemical, hematological and immunological parameters in beluga (Huso huso). Fish were divided into 4 groups before being fed for 8 weeks with 0%, 3%, 6% and 12% of nettle. The blood samples were collected on week 4 and 8.

Nasal tuberculosis in a 56 year old woman.

Background: Nasal tuberculosis (NTB) is rare, but it can be caused by either a pulmonary disease or a retrograde involvement of the nose by lupus vulgaris of the facial skin. In this study, we present a case of NTB with an ulcerative lesion in her left nasal cavity.

Case Presentation: A 56 years old woman presented with an ulcerative lesion in her left nasal cavity.

In vitro evaluation of the efficacy of liposomal and pegylated liposomal hydroxyurea.

Breast cancer is one of the most frequent cancer types within women population. Hydroxyurea (HU) is a chemotherapy compound for treatment of patients with cancer diagnosis, including breast cancer associated with several adverse effects. In this study, we applied nanotechnology to decreased drug side effects along with improvement of therapeutic index.

The effects of transcatheter valve crimping on pericardial leaflets.

Background: Transcatheter aortic valve replacement has emerged as a promising therapy for treatment of severe aortic stenosis. Although it has been shown that these valves can be safely delivered and implanted, studies of valve longevity are lacking because of the infancy of the technology. Particularly, the effects of stent crimping on the valve's leaflets have not yet been sufficiently investigated.

Efficacy of Cisplatin-loaded polybutyl cyanoacrylate nanoparticles on the glioblastoma.

Glioblastoma is known as one of the most aggressive human cancers. To gain access of the brain, therapeutic agents must overcome blood-brain barrier (BBB). In this study, Cisplatin (Cispt)-loaded polybutylcyanoacrylate (PBCA) nanoparticles (NPs) were prepared through miniemulsion polymerization technique.

Study of toxicity effect of pegylated nanoliposomal artemisinin on breast cancer cell line.

Nano carriers have greatly revolutionized the treatment of most diseases recently. One of these nano carriers, liposomes, has got particular significance. On the other hand, Artemisinin which is used as an effective anticancer drug has some side effects.

Cytotoxicity of liposomal Paclitaxel in breast cancer cell line mcf-7.

Regarding that the breast cancer is the most prevalent disease among women, paclitaxel, an anti-cancer drug, could be used in treatment of this disease. As paclitaxel has adverse effects, it was used of nanoliposome drug delivery technology in order to reduce adverse effects and improve drug efficacy. Certain ratios of phosphatidylcholine, cholesterol and paclitaxel were synthesized to prepare nanoliposomal paclitaxel.

Drug delivery of hydroxyurea to breast cancer using liposomes.

It is clear that cancer is one of the most mortal diseases in the world and the most prevalent among women is breast cancer. As hydroxyurea (HU)-a drug which is used in chemotherapy-has many adverse effects in long-term despite of its therapeutic properties, we made use of nano drug delivery technology in order to reduce adverse effects and increase therapeutic index. Thus, liposomation is a novel way in drug delivery systems.

Hemophagocytic lymphohistiocytosis complicating erythroleukemia in a child with monosomy 7: a case report and review of the literature.

Herein, the first case of childhood erythrophagocytosis following chemotherapy for erythroleukemia in a child with monosomy 7 is reported. A 5-year-old boy presented with anemia, thrombocytopenia, and hepatosplenomegaly in whom erythroleukemia was diagnosed. Prolonged pancytopenia accompanied by persistent fever and huge splenomegaly and hepatomegaly became evident after 2 courses of chemotherapy.

Roles of extracellular ions and pH in 5-HT-induced sperm motility in marine bivalve.

Factors that inhibit and stimulate the initiation of sperm motility were determined for Manila clam (Ruditapes philippinarum), Pacific oyster (Crassostrea gigas), and Japanese scallop (Patinopecten yessoensis). Compared with artificial seawater (ASW), serotonin (5-hydroxytryptamine creatinine sulfate, 5-HT) could fully trigger sperm motility and increase sperm velocity and motility duration. Sperm motility was decreased in ASW at pH 6.

Diagnostic value of electrocardiography compared with echocardiography in measuring left ventricular mass index in major thalassemia patients over 10 years of age.

The Effects of Cooking Process and Meat Inclusion on Pet Food Flavor and Texture Characteristics.

The pet food industry is an important portion of the food and feed industries in the US. The objectives of this study were (1) to determine cooking method (baking or extrusion), meat inclusion (0 or 20%), and extrusion thermal to mechanical energy ratios (low, medium, and high) effects on sensory and volatile properties of pet foods, and (2) to determine associations among sensory and volatile characteristics of baked and extruded pet foods. Descriptive sensory analysis and gas chromatography-mass spectrometry were used to analyze the pet food samples.
