background: toxoplasma gondii is the most common parasite causing latent cerebral infections in human. it has been shown that some anti-psychotic drugs are able to inhibit the proliferation of the parasite in in vitro study. there is very limited data regarding the inhibitory effect of anti-psychotics on toxoplasma in in vivo . in this study, we evaluated anti- toxoplasma activity of fluphenazi...
به منظور بررسی قابلیت مهار آفلاتوکسین b1 توسط پروبیوتیک باسیلوس، آزمایش های in vitro و in vivo انجام شد. از محتویات دستگاه گوارش 40 قطعه طیور مختلف 350 ایزوله باسیلوس جداسازی گردید. پس از انجام تست های پروبیوتیکی رایج و آزمون آفلاتوکسین زدایی بر روی جدایه ها ، یک جدایه که واجد بالاترین صفات مورد بررسی بود انتخاب و به عنوان laterosporus (bl) berevibacillus شناسایی گردید و در آزمایش مزرعه ای مورد...
semen quality and its relationship to fertility are major concern in animal production. the aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through artificial insemination(ai). semen samples were collected from four buffalo bulls. semen volume and sperm concentration appeared to be significantly different (p0...
سابقه و هدف: نانو مواد شامل موادی در اندازۀ 1 تا 100 نانومتر و یا حتی کوچک تر هستند که می توانند به راحتی از پوست، آلوئولهای ریه و حتی از جفت عبور کنند. به همین منظور، به مطالعۀ تاثیرات نانو اکسید روی بر تکوین جوانه اندام حرکتی جنین موشها پرداخته شد. روش بررسی: پژوهش تجربی به طریقه in vivo صورت گرفت. موش های باردارگروه های تجربی در روز11 بارداری، مورد تزریق یک بار نانواکسیدروی، در دوزهای g/kg 5...
objective(s): medicinal benefits of quantum dots have been proved in recent years but there is little known about their toxicity especially in vivo toxicity. in order to use quantum dots in medical applications, studies ontheir in vivo toxicity is important. materials and methods:cdse:zns quantum dots were injected in 10, 20, and 40 mg/kg doses to male mice10 days later, mice were sacrificed ...
The chemical shift sensitivity and significant signal enhancement afforded by laser-polarized 129Xe have motivated the application of 129Xe NMR to biological imaging and spectroscopy. Recent research done by our group has used laser-polarized 129Xe in biomolecular assays that detect ligand-binding events and distinguish protein conformations. The successful application of unfunctionalized and f...
RNA interference (RNAi), an effective technique for regulating or silencing specific genes, can be applied to treat various diseases. Multiple clinical trials using RNAi are ongoing, and molecular imaging can serve as a powerful tool in RNAi-based therapies. This brief review will highlight the current progress on in vivo imaging of RNAi delivery and silencing effects. Incorporation of suitable...
The molecular charge of fluorescent bioprobes has recently received much attention due to its influence on cellular uptake. Herein, we demonstrate the effect of the molecular charge of glucose bioprobes on their GLUT-specific cellular uptake. We also applied GB2-Cy3 to in vivo imaging in the zebrafish model.
Indocyanine green (ICG) is widely used in medical imaging and testing. Its complex spectral behavior and low quantum yield limits some applications. We show that proximity of ICG to a metallic silver particle increases its intensity approximately 20-fold and decreases the decay time. Since the rate of photobleaching is not increased, our results suggest that ICG-silver particle complexes can yi...
The combination of two-photon in vivo imaging and genetic labeling of specific cell types in the mouse brain is a powerful method to refine our understanding of brain circuitry and to dissect the contribution of specific neural classes to cortical function. The synthetic calcium indicators are the best fluorescent reporters for cellular activity that are presently available but their spectral p...
