Background: Alzheimer’s is progressive dementia with loss of nerve cells. Physical activity and the use nano-pharmaceutical supplements may prevent progression Alzheimer’s. The aim this study was to investigate effects resistance training Folate nano-liposome on expression D1 D2 receptors in hippocampal tissue rats. Methods: Thirty-three male Wistar rats at age eight weeks were prepared from Pa...

RATIONALE AND OBJECTIVE Receptor-targeted delivery of imaging and therapeutic agents can lead to enhanced efficacy for both. Multimodality imaging offers unique advantages over traditional single modality imaging. Tumor marker folate receptor (FR)-targeted fluorescent paramagnetic bimodal liposomes were synthesized to co-deliver paramagnetic and fluorescence agents for magnetic resonance (MR) a...

The clearance rate of liposomal drugs from the circulation is determined by the rate and extent of both drug release and uptake of liposomes by cells of the mononuclear phagocyte system (MPS). Intravenously injected liposomes initially come into contact with serum proteins. The interaction of liposomes with serum proteins is thought to play a critical role in the liposome clearance. Therefore, ...

phatidylcholine liposomes (PC-liposomes). They were also stable in fresh rat plasma at 37•Ž. The biological behavior (blood clearance, urinary excretion and tissue distribution) of the vesicles based on palmitoyl serine (PSer-liposomes) or palmitoyl glutathione (PGSH-liposomes) was examined after intravenous injection in rats. The synthetic liposomes were cleared very rapidly from the blood com...

CONTEXT Fusogenic liposomes are unique delivery vehicles capable of introducing their contents directly and efficiently into the cytoplasm. OBJECTIVE The objective of this study was to evaluate the potential of fusogenic liposomes containing Sirolimus to improve its anti-proliferative effect on T-lymphocyte cells. MATERIALS AND METHODS Conventional liposomes containing Sirolimus were prepar...

Functional and ultrastructural studies of liposomes injected i.v. into inbred C57BL/6N mice were performed to determine whether free liposomes can traverse capillaries. In the liver and spleen, organs with discontinuous (sinusoidal) capillaries, ultrastructural and cell fractionation studies revealed that small (300- to 800-A diameter), sonicated, unilamellar liposomes were more efficient in pe...

Intravenously administered liposomes are versatile carriers for drugs, contrast agents, biologics, and DNA. Liposomes and other colloidal particles are currently under investigation as lymph node delivery vehicles. After s.c. injection, conventional liposomes move into the lymphatic vessels, but are poorly retained in each draining lymph node (<2% injected dose). In this report, we describe a n...

A better understanding of the interrelationships between the structure and function of the large arteries would lead to optimize cardiovascular disease prevention strategies. In this study, we investigated the relationships of aortic arterial stiffness assessed by carotid-femoral pulse-wave velocity (PWV), with carotid plaque echogenicity assessed by B-mode ultrasound. We analyzed 561 subjects ...

Maleimide is a stable and easy-to-handle moiety that rapidly and covalently conjugates thiol groups of cysteine residues in proteins or peptides. Herein, we use maleimide to modify the surface of liposomes in order to obtain an advanced drug delivery system. Employing a small amount (0.3 mol%) of maleimide-polyethylene glycol (PEG) to modify the surface of the liposomes M-GGLG-liposomes, compos...

objective:platycladus orientalis or thuja orientalis is a native plant of iran different parts of which are used in the treatment of various diseases such as: gout, rheumatoid arthritis, common cold, cough, bronchitis, asthma, high blood pressure and hormonal disorders like hirsutism and baldness. also, various organs of this species have been used as appetizer. the purpose of this study was to...
