اختلال دوقطبی یک ناهنجاری روانی جدی است که جزء مهمترین عوامل ناتوانی در میان بیماری های روانی محسوب می شود و حدود یک درصد از جمعیت را تحت تاثیر قرار می دهد. استرس اکسیداتیو در فیزیولوژی آسیب بیماران مبتلا به اختلال دوقطبی نقش مهمی بازی می کند و مطالعات از افزایش آسیب های dna ناشی از این استرس در این بیماران خبر می دهند. xrcc4 و xrcc5 پروتئین های درگیر در مسیر ترمیمی non-homologous end joining (...
The reaction of the sterically saturated uranium(III) tetrasilylamido complex [K(18c6)][U(N(SiMe3)2)4] with CO2 leads to CO2 insertion into the U-N bond affording the stable U(IV) isocyanate complex [K(18c6)][U(N(SiMe3)2)3(NCO)2]n that was crystallographically characterized. DFT studies indicate that the reaction involves the [2+2] cyclo-addition of a double bond of O=CO to the U-N(SiMe3)2 bond...
Intravenous (IV) insertion is one of the most common invasive procedures that causes pain, fear, and even stress for children. Uncontrolled anxiety feeling can develop into excessive create a permanent traumatic impact on child's life. Children need to know about procedure they will face in interesting way. This study purpose identify effectiveness providing information through animated educati...

We describe the synthesis of [bis(N-(3-tert-butylsalicylidene)anilinato)] titanium (IV) dichloride (Ti-FI complex) and examine the effects of comonomer (feed concentration and type) on its catalytic performance and properties of the resulting polymers. Ethylene/1-hexene and ethylene/1-octene copolymers were prepared through copolymerization using Ti-FI catalyst, activated by MAO cocatalyst at 3...

nicotine is one the chemical substance with high level of toxically. it crosses the placenta and accumulates in the developing organs of fetus. our previous investigations indicated that collagen type iv plays a key role in basement membrane of various embryonic organs. in this study we evaluated the effect of maternal nicotine exposure pre and postnatal period on collagen iv expression during ...
iv therapy is an important option in incapable patients’ treatment. in this paper, we discuss about: a) for best control of them, we must know about what materials are in these drugs? b) for what reason they are use? c) what errors may be happen in use of them? amount of iv fluids must be accommodating with loss of fluids. firstly, we review amount of main body fluids. main part of our body wei...
