This paper discusses the influence of peripheral blood smear morphology methods on the electrical impedance spectroscopic characteristics of blood samples from ischemic stroke patients. In this study, there were 26 blood samples, consisting of a control group with 5 blood samples and a group of ischemic stroke patients with 21 samples with varying degrees of severity. The methods used are electrical impedance spectroscopy (EIS) and whole blood cell morphology methods. The EIS method was carried out using the BISDAQ tool and application, and results were obtained in the form of Bode Plot, Bode Phase Plot, Nyquist Plot, and measurement data values in the form of Ms. Excel. Meanwhile, the Morphological method is carried out by making a peripheral blood smear, then viewing and obtaining an image using a digital microscope, and then counting the number of cells using the Image Raster application. Based on the results of the method carried out, the correlation can be seen to conclude that whole blood cell morphology greatly influences the characteristics of EIS and determines the severity of ischemic stroke patients.

In this study, the effect of a magnetic field on a Flint Glass for optical isolator applications has been reported. A flint glass and a laser light source with a wavelength of 650nm were used as a medium and a light source, respectively. The magnetic field was produced by applying a current through a coil. The linearly polarized light was passed through the medium in the presence of a magnetic field, and the angle of rotation was measured. The angle of rotation was plotted versus magnetic field strength and fitted linearly. The experimental results showed that the flint glass becomes optically active in the presence of a magnetic field because it rotates the plane of linearly polarized light, and this rotation increases with respect to the magnetic field linearly. The Verdet constant was calculated for 650nm, which is a large coefficient for the rotation of the plane of polarized light.

In this paper, the bandgap of Germanium (Ge) and Zinc-Oxid (ZnO) materials were studied using two different techniques called the four-probe method and UV-Visible spectroscopy. A chip of Ge and a ZnO synthesized Nanorods on the FTO substrate were utilized as the samples. Scanning electron microscopy and X-ray diffraction spectroscopy were applied to understand the morphology and the crystal structure of the ZnO particles on the substrate. To get bandgap for Ge, the variation of voltage concerning temperature in current was recorded, and for ZnO- Nanorods (NRs), the absorption spectra in the range of (200-800) nm were taken. Based on obtained data and calculations, the band gap of Ge and ZnO-NRs were determined to be around and respectively. It revealed that the bandgap of compound semiconductors (ZnO- NRs) could be sufficiently large as compared to the elemental semiconductors (Ge), and through that, the modification of various devices is possible in the industry.

Methanol and ethanol can be produced from many kinds of feedstock. One of the most preferred methods to synthesize methanol is from natural gas, which is reformed to form synthesis gas (syngas) and converted by a catalyst to form methanol. Conversely, ethanol production mostly comes from biomass, which competes with human food fulfilment. Several pieces of literature conduct syngas transformation to ethanol to solve this problem. However, the experiment is conducted on a lab scale or pilot scale. Before the technology can be mass-produced on a plant scale, we must determine the most suitable operating condition for the reactor to escalate the reactor's productivity. This study is aimed to determine the optimal operating condition for the integrated methanol and ethanol plant, which is the reactors. The software used for the study is Aspen Plus V12.1. The independent variables for all the reactors in this study are the pressure (P) and the temperature (T). We add the feed molar flow ratio as the independent variable for the Steam Methane Reforming (SMR) and the ethanol synthesis reactor. The dependent variable that will be used for the determination of the optimal operating condition of the reactors is the reactant conversion and the product yield. The data validation between the experimental data conducted by other authors and the process modeling result is in good agreement with less than 6% of error for all three reactors. After performing the process simulation and sensitivity analysis to determine the optimal operating condition for the reactors, it is found that the optimal operating condition for the reactors is as follows: (1) SMR reactor: 25 bar pressure, 1,223 K temperature, feed molar flow ratio (H2O/CH4 ratio) of 3, (2) methanol synthesis reactor: 100 bar pressure and 503 K temperature, and (3) ethanol synthesis reactor:110 bar pressure, 583 K temperature, and feed molar flow ratio (H2/CO ratio) of 0.75.
甲醇和乙醇可以由多种原料生产。合成甲醇最优选的方法之一是天然气，天然气经重整形成合成气(syngas)，再经催化剂转化生成甲醇。相反，乙醇生产主要来自生物质，这与人类的食物供应竞争。有几篇文献通过合成气转化为乙醇来解决这一问题。然而，该实验是在实验室规模或试点规模上进行的。在该技术可以在工厂规模上大规模生产之前，我们必须确定最适合反应堆的操作条件，以提高反应堆的生产率。本研究旨在确定甲醇乙醇一体化装置的最佳操作条件，即反应器。该研究使用的软件是Aspen Plus V12.1。本研究中所有反应器的自变量均为压力(P)和温度(T)，并将进料摩尔流量比作为蒸汽甲烷重整(SMR)和乙醇合成反应器的自变量。用于确定反应器最佳操作条件的因变量是反应物转化率和生成物收率。其他作者的实验数据与过程建模结果的数据验证吻合良好，三个反应器的误差均小于6%。通过过程模拟和灵敏度分析确定反应器的最佳运行条件，发现反应器的最佳运行条件为:(1)SMR反应器:压力25 bar，温度1223 K，进料摩尔流量比(H2O/CH4比)为3;(2)甲醇合成反应器:压力100 bar，温度503 K;(3)乙醇合成反应器:压力110 bar，温度583 K，进料摩尔流量比(H2/CO比)为0.75。

Ziziphus mauritiana is a plant species belonging to the Rhamnaceae family. It is commonly found in tropical and subtropical regions of Asia, and in Indonesia, this plant grows wild and thrives on the islands of Bali, Lombok and Sumbawa. The fruits of Z. mauritiana are edible, however, in Indonesia, it is underutilized and has very low economic value. To evaluate its possibility to be developed as a functional food, this study was conducted to determine the total phenolics and flavonoids, dietary fiber, and nutrients contained in the fruit juice of Ziziphus mauritiana. Total phenols and flavonoids contents were determined using Folin Ciocalteu and AlCl3 methods, respectively. The in vitro antioxidant activity of the juice was evaluated using the DPPH method. The content of soluble and insoluble dietary fiber was determined using the standard AOAC analysis method, and proximates analysis was conducted in accordance with SNI 01-2891-1992. The results of this study revealed that freeze-dried juice of Z. mauritiana fruit has total phenols content of 1690 mg GAE/100g, total flavonoids of 15.10 mg QE/100g, soluble dietary fiber of 0.61%, and insoluble dietary fiber 2.03%. However, the antioxidant activity of Ziziphus mauritiana fruit juice was weak with IC50 328.54 ppm. The proximate analysis revealed the crude fiber in the freeze-dried fruit juice was 0.56%, carbohydrates 82.43%, protein 3.34%, fats 0.31%, ash 3.62%, and water 10.30%. In conclusion, Ziziphus mauritiana fruit juice has a high content of total phenolic substances, high dietary fiber, and high nutritional value, therefore it has a good potential to be developed as a functional food.

This study aims to develop a new set of added variables to calculate the chemical shift N-15 based on quantum mechanics methods for a number of periodic compounds using theoretical chemistry (Gaussian V.12, 2010). The relationship between the experimental N-15 was conducted with two mechanical variables, such as SPSS V 2019. The relationship between the theoretical chemical shift values of the N-15 atom nucleus and practical values in literature was examined. Two quantitative mechanical methods are used to extract information to calculate the N-15 chemical shift, the traditional method, the other AB Initio method, and the DFT job theory. The success of the method is determined in terms of the values of the correlation coefficient (R) and the standard error (SE), as well as the material meaning of the specified variables. A good consensus is seen between practical and theoretical values. A comparison was made between the two methods to find out the best in the chemical transformation account. The DFT method gave better results.

The DFT method gave better results.","PeriodicalId":127127,"journal":{"name":"International Journal of Biological, Physical and Chemical Studies","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126306127","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}
Ferroptosis is a recently identified form of non-apoptotic regulated cell death (RCD). It is primarily characterized by the accumulation of lipid peroxide, which is iron-dependent. Ferroptosis is essential for the treatment of tumors, renal failure, and ischemia reperfusion exposure (IRI). Ferroptosis and nanomedicine are now the subjects of intense study and clinical attention. There is, however, a limited amount of data on the precise molecular pathways behind ferroptosis and the contribution of nanoparticles. This work provides a thorough overview of ferroptosis, its regulations, and the various mechanisms by which iron- and non-iron-based nanoparticles potentially trigger ferroptosis in the context of cancer therapy. We investigated the most recent developments in ferroptosis research and nanoparticles as ferrotosis-inducing agents by performing extensive literature studies based on the notion of ferroptosis and cancer therapy and a thorough examination of various publications regarding nanoparticles. Our results suggest that tumor suppression and treatment efficacy can both be enhanced by ferroptosis triggered via nanoparticles. New ideas and viewpoints have also been put out for the treatment of ferroptosis-induced cancer, which will make a significant contribution to cancer therapy.

Fruits are rich in fiber and antioxidant compounds that can prevent and treat health disorders related to oxidative stress caused by high-fat high-cholesterol diet (HFHCD). Bouea macrophylla is a tropical fruit plant with edible juicy fruits. In this study, we conducted experiments to prove the effectiveness of B. macrophylla fruit juice (BMFJ) as an antioxidant agent in rats fed with HFHCD. Male Sprague Dawley rats were fed with HFHCD for 100 days and simultaneously orally supplemented with BMFJ. Atorvastatin was used as a positive control. At the end of the experiment, the blood and hepar were collected and assayed for malondialdehyde (MDA). The in vitro antioxidant activity of BMFJ was also evaluated using the DPPH method. Total phenols and flavonoids contents were determined using Folin Ciocalteu and AlCl3 methods, respectively. Results of the experiments showed that total phenols and flavonoids in BMFJ were 570 mg GAE/g and 31.89 mg QE/g, respectively, and the IC50 of radical scavenging activity was 564.271 ppm. The in vivo antioxidant evaluation showed that supplementation of BMFJ significantly prevents the increase of MDA levels, both in serum and liver of rats fed with HFHCD. These findings clearly indicate that supplementation of B. macrophylla fruit juice significantly prevents oxidative stress in rats fed with high-fat high-cholesterol diets through attenuation of lipid peroxidation.

Ziziphus mauritiana is an edible fruiting plant commonly found in Asia. In Indonesia, this plant grows wild and thrives on the islands of Bali, Lombok, and Sumbawa. Although it is edible and has good potential as food and medicinal ingredient, in Indonesia, the fruits of Z. mauritiana are underutilized and have almost no economic value. Information about the bioactivity and chemical content of the fruit is limited. To evaluate its possibility of being developed as functional food, a GC-MS and LC-MS/MS analysis was carried out to identify the phytochemical content of the fruit juice. From the GC-MS chromatogram, four compounds were identified with a quality match of 85% and above. The compounds were 5-( hydroxymethyl)-2–furancarboxaldehyde (43.45%), 5, 5'-(oxybis(methylene)) bis-2- furancarbox-aldehyde (25.99%), 2,3–dihydro-3,5–dihydroxy–6–methyl-4H–pyran–4-one (6.05%), and hexadecanoic acid (2.16%). The result of the LC-MS/MS analysis showed 42 peaks of different chemical compounds and included several groups of compounds such as flavonoids, alkaloids, phenols, terpenoids, and organic acids. From these results, it can be concluded that Ziziphus mauritiana fruit juice contains various chemical compounds that are likely to have medicinal activity and therefore has good potential to be used and developed as a functional food.
