Incorporation of methotrexate into coconut oil nanoemulsion potentiates its antiproliferation activity and attenuates its oxidative stress.

Methotrexate (MTX), a chemotherapeutic agent, has limited clinical applications due to its pulmonary and neurotoxicity. The antineoplastic activity of MTX-NE COCO, which is MTX formulated in coconut oil nanoemulsion (NE), was evaluated in A549 non-small cell lung cancer cells while its adverse side effects on the oxidative stress of the lung and brain were assessed in mice. The -average diameter for the dispersed nanodroplet of MTX-NE COCO (79.

Osteoporosis knowledge and awareness among university students in Saudi Arabia.

Unlabelled: Awareness and knowledge about any disease is the first step to prevent and treat it, so this study evaluates osteoporosis awareness and knowledge in university students. Our results showed a high awareness and good knowledge of osteoporosis. Females were better informed than males.

Evaluation of the Anticancer Activity of the Gemcitabine and Doxorubicin Combined in a Nanoemulsion.

Context: Doxorubicin (DOX) and gemcitabine (GEM) are anticancer drugs that were combined in a nanoemulsion (NE) to reduce their adverse side effects.

Aim: To detect the antitumor activity of the combination formulas of GEM and DOX, loaded either in water (GEM+DOX-Sol) or in NEs (GEM-DOX combination/loaded NE [GEM+DOX/LNE]), in female Swiss albino mice inoculated with Ehrlich ascites carcinoma (EAC).

Settings And Design: The anticancer assessment of the NE formulas was implemented in 200 mice, which were divided into 10 groups.

Protective effect of melatonin against zonisamide-induced reproductive disorders in male rats.

Introduction: Zonisamide (ZNS) is a modern antiepileptic drug (AED) that is distinguished from other AEDs by its unique structure and broad mechanistic profile. The pineal hormone melatonin is involved in the regulation of reproductive function, including the timing of the luteinizing hormone (LH) surge. The aim of the present work was to study the protective effect of melatonin against the potential suppression impact of ZNS on reproductive activity.

Effect of melittin on mice stomach.

Melittin, the main bee venom component, has many positive biological effects and a relatively low toxicity in various cell types. However, there is no evidence of the effect of melittin on gastrointestinal cells. In the present study, we investigated the histological and immuonohistochemical effects of melittin on mice stomach.

Neuronal activation and plasticity in Schistosoma mansoni infected mice.

Schistosomiasis leads to structural and functional changes which may result from unbalanced release of some inflammatory mediators. The aim of the study was to investigate the effect of intestinal parasitic infection on nitric oxide release and to evaluate the neural plasticity that leads to motility disturbance. Experiments were performed in Swiss mice 8- and 12-weeks following infection with Schistosoma mansoni compared to untreated controls.

Somatostatin sst(2) receptors inhibit peristalsis in the rat and mouse jejunum.

Somatostatin [somatotropin release-inhibitory factor (SRIF)] has widespread actions throughout the gastrointestinal tract, but the receptor mechanisms involved are not fully characterized. We have examined the effect of selective SRIF-receptor ligands on intestinal peristalsis by studying migrating motor complexes (MMCs) in isolated segments of jejunum from rats, mice, and sst(2)-receptor knockout mice. MMCs were recorded in 4- to 5-cm segments of jejunum mounted horizontally in vitro.
