TiO 2 nanoparticles were prepared by using electrochemical anodization method. UV-Vis absorption spectrum of TiO 2 and TiO 2 : piperine nanoparticles have an absorption edge in the range of (340 -355) nm, suggesting that the TiO 2 colloidal obtained is anatase phase. The band gap energy (E g ) for TiO 2 nanoparticles (3.46 eV) is higher than the value of (3.20 eV) for bulk TiO 2 . X-Ray diffraction results for TiO 2 nanoparticles with a wavelength of 1.54 Å were investgation in this work. Planes (101), (200), (111), (220), (210), (211), (105), (220), (310), (221), and (220) crystal planes all had peaks with the lattice constants a = 3.755 Å and c = 9.5114 Å confirms the anatase phases of the TiO 2 nanoparticles according to the JCPDS file 21-127231. Scanning Electron Microscope images of TiO 2 samples in revealed the prevalence spherical nanosized crystallites, where clear nanostructures with a grain size of 15 nm. In TEM image, the shape of the nanoparticles was spherecial, with small size variance and found to be 15 nm. The EDX study of the nanoparticle reflects the atomic percentage of elements such as Ti and O with a ratio of 83:17 and no other peaks are observed this confirm the presence of TiO 2 nanoparticles.

Loading rHuEPO-alpha drug on the surface of magnesium oxide nanoparticles further improves the effect of the drug as a treatment for anemia. After preparation of magnesium oxide nanoparticles by precipitation method, it was diagnosed by X-ray diffraction and Transmission Electron Microscopy. the loaded was diagnosed by Docking program, UV-Visible and Transmission Electron Microscopy. The study of LD50 was for thirty male mice. Magnesium Oxide nanoparticles had an average crystallite size of 8.42 nm. oral LD50 test was 896 mg/kg. Docking results presented a high energy binding with force linkage due to the link of the oxygen atom of MgO NPs with three hydrogen bonds of amino acids in the rHuEPO-alpha structure. The UV-Visible result was certain that all rHuEPO-alpha drug was loaded on the surface of MgO NPs. TEM shows that the average particle size was 9.94 nm after loaded of the rHuEPO-alpha drug on MgO NPs while was 9 nm before the loaded. Magnesium oxide nanoparticles may exhibit an effect on increasing the efficacy of rHuEPO-alpha after the loaded, leading to elevated hemoglobin and reduced anemia disease.
在氧化镁纳米颗粒表面加载rhuepo - α药物,进一步提高了药物治疗贫血的效果。用沉淀法制备氧化镁纳米颗粒后,用x射线衍射和透射电镜对其进行诊断。通过对接程序、紫外可见和透射电镜对载荷进行了诊断。LD50的研究以30只雄性小鼠为对象。氧化镁纳米颗粒的平均晶粒尺寸为8.42 nm。口服LD50试验为896 mg/kg。对接结果显示,由于MgO NPs的氧原子与rhuepo - α结构中氨基酸的三个氢键相连,形成了一个高能的力键结合。紫外可见结果表明,所有rhuepo - α药物均被负载在MgO NPs表面。TEM结果表明,负载rhuepo - α药物后的平均粒径为9.94 nm,负载前的平均粒径为9 nm。氧化镁纳米颗粒可能在负载后增加rhuepo - α的功效,导致血红蛋白升高和贫血疾病减少。

As a result of increasingly rigorous environmental legislation and industry adoption of waste minimization recommendations, the development of recycling and reuse possibilities for metal-related trash has become increasingly important.Inthis research, calcium oxide and mixture of calcium, iron, and magnesium oxides was extracted from the wastes of cement factories using hydrofluoric acid. As a result, this research provides a comprehensive picture of waste recycling, and reuse throughout extraction and it examines the current state and potential developments in mineral and metal waste recycling and reusing them in different applications, among these applications, it is used CaO and CaO:MgO:Fe2O3 NPs in medical applications, including uterine cancer. Characterizations of the extracted nano-products were done using (XRD) which confirmed the crystalline nature of CaO and the mixture of CaO:MgO:Fe2O3 NPs. More, (FESEM) has been used to demonstrate the morphology of the nanostructures of CaO and the mixture CaO:MgO:Fe2O3 NPs. The data yielded the average grain size of CaO and the mixture CaO:MgO:Fe2O3 NPs calculated by SEM and XRD (64.08, 84.2) nm and (38.636, 31.597) nm respectively. (EDS) spectrum and XRD pattern suggested that prepared CaO and the mixed CaO:MgO:Fe2O3 NPs were highly pure. In addition, the ability of NPs as a promising anticancer agent was tested against MES-SA cells line, according to the MTT assay results of MESSA cells the IC50 (91.65 and 98.4) μg/mL for CaO and CaO:MgO:Fe2O3 NPs respectively. The results showed that the extracted nanoparticles CaO and the mixture CaO:MgO:Fe2O3 NPs served as an anticancer agent.

In this research, investigated characterization of pure and Cobalt doped Tin dioxide SnO2:Co with 3, 5 and 7 wt% fabricated using radio frequency magnetron sputtering method deposited on glass surfaces. The results showed that prepared SnO2:Co were nano films and poly crystalline in form with favored reflection permanently (110) plan, and the crystallite size decreases as the Co concentration increased 9-14 nm. The optical properties represented by the transmittance of perspicuous and cobalt transplantation SnO2 layers were studied and results showed that highest transmittance obtained was 91% in the pure films and decreased to 78% as the Co concentration increased; the wavelength range was 300-900 nm due to be the increasing of the Co amount during the deposition, leading to a linear increase in mobility and carrier concentration, until a threshold of Co content was overcome and from that point onward the mobility began to decrease. Optical energy gaps of perspicuous and Co transplantation SnO2 nano layers were determined and the energy gap was reduced from 3.50 eV of perspicuous nano layers to 3.29 eV for the highest transplantation concentration.
在本研究中,研究了使用射频磁控溅射法在玻璃表面沉积的纯和钴掺杂的二氧化锡SnO2:Co(重量百分比分别为3、5和7)的表征。结果表明,所制备的SnO2:Co是纳米薄膜和多晶结构,具有良好的永久反射(110)平面,并且随着Co浓度的增加,晶粒尺寸减小。研究了渗层和钴移植SnO2层的透光率所代表的光学性能,结果表明,在纯膜中获得的最高透光率为91%,并且随着Co浓度的增加而降低到78%;波长范围为300-900nm,这是由于沉积期间Co量的增加,导致迁移率和载流子浓度的线性增加,直到Co含量的阈值被克服,并且从那时起迁移率开始降低。测定了出汗和共移植SnO2纳米层的光学能隙,并且对于最高移植浓度,能隙从出汗纳米层的3.50eV减小到3.29eV。

The results showed that prepared SnO2:Co were nano films and poly crystalline in form with favored reflection permanently (110) plan, and the crystallite size decreases as the Co concentration increased 9-14 nm. The optical properties represented by the transmittance of perspicuous and cobalt transplantation SnO2 layers were studied and results showed that highest transmittance obtained was 91% in the pure films and decreased to 78% as the Co concentration increased; the wavelength range was 300-900 nm due to be the increasing of the Co amount during the deposition, leading to a linear increase in mobility and carrier concentration, until a threshold of Co content was overcome and from that point onward the mobility began to decrease. Optical energy gaps of perspicuous and Co transplantation SnO2 nano layers were determined and the energy gap was reduced from 3.50 eV of perspicuous nano layers to 3.29 eV for the highest transplantation concentration.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44415427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capsaicin is an alkaloid molecule with outstanding biological activity. Several reports have shown that capsaicin exerts significant antitumoral effects in several cancer cell lines, including gliomas. However, its application has been very limited due to its hydrophobicity, low affinity, and short life span. Gliomas are a heterogeneous group of brain malignant tumors with increasing prevalence worldwide. Standard therapy against these tumors generally includes resection by surgery, radiation, and chemotherapy or their combination. However, elicitation of tumor resistance to chemical or radiation treatments remains one of the main challenges to be resolved, particularly in the case of glioblastomas. Nanotechnology is an innovative approach to the treatment of Central Nervous System diseases and especially to gliomas treatment. Indeed, the use of nanotherapeutic formulations offers several advantages over the conventional methods of drug delivery therapy. In this review, we analyzed the current literature regarding the development of capsaicin-loaded nanoparticles as a promising approach for the treatment of malignant brain tumors.
辣椒素是一种具有突出生物活性的生物碱分子。一些报道表明,辣椒素对包括胶质瘤在内的几种癌症细胞系具有显著的抗肿瘤作用。然而,由于其疏水性、低亲和力和短寿命,其应用非常有限。胶质瘤是一组异质性脑恶性肿瘤,在世界范围内发病率不断上升。针对这些肿瘤的标准治疗通常包括通过手术、放疗和化疗或其组合进行切除。然而,激发肿瘤对化学或辐射治疗的耐药性仍然是需要解决的主要挑战之一,尤其是在胶质母细胞瘤的情况下。纳米技术是治疗中枢神经系统疾病,特别是神经胶质瘤的一种创新方法。事实上,与传统的药物递送治疗方法相比,纳米治疗制剂的使用提供了几个优势。在这篇综述中,我们分析了目前关于开发负载辣椒素的纳米颗粒作为治疗恶性脑肿瘤的一种有前途的方法的文献。
