Thymoquinone-rich black cumin oil attenuates ibotenic acid-induced excitotoxicity through glutamate receptors in Wistar rats

Inflammation-mediated alterations in glutamate neurotransmission constitute the most important pathway in the pathophysiology of various brain disorders. The excessive signalling of glutamate results in excitotoxicity, neuronal degeneration, and neuronal cell death. In the present study, we investigated the relative efficacy of black cumin (Nigella sativa) oil with high (5 % w/w) and low (2 % w/w) thymoquinone content (BCO-5 and BCO-2, respectively) in alleviating ibotenic acid-induced excitotoxicity and neuroinflammation in Wistar rats. It was found that BCO-5 reversed the abnormal behavioural patterns and the key inflammatory mediators (TNF-α and NF-κB) when treated at 5 mg/kg body weight. Immunohistochemical studies showed the potential of BCO-5 to attenuate the glutamate receptor subunits NMDA and GluR-2 along with increased glutamate decarboxylase levels in the brain tissues. Histopathological studies revealed the neuroprotection of BCO-5 against the inflammatory lesions, as evidenced by the normal cerebellum, astrocytes, and glial cells. BCO-2 on the other hand showed either a poor protective effect or no effect even at a 4-fold higher concentration of 20 mg/kg body weight indicating a very significant role of thymoquinone content on the neuroprotective effect of black cumin oil and its plausible clinical efficacy in counteracting the anxiety and stress-related neurological disorders under conditions such as depression and Alzheimer's disease.

Investigation the Effect of Different Oils as Separating Medium on Surface Roughness and Hardness of Tissue Surface of Flexible Denture Base

Background: Flexible dentures (thermoplastic material) are ideal alternatives to traditional methyl methacrylate dentures, since they not only give exceptional aesthetics and comfort, but also adapt to the continual movement of partially edentulous patients. During the manufacturing of acrylic denture base material, an effective separating medium must be used to separate the denture cleanly from the plaster to avoid direct contact between the denture base material and the mould surface.
 Objective: The goal of this study was to investigate the effect of several types of oil (glycerin oil, olive oil, and black castor oil) on the surface roughness and hardness of flexible denture base material compared with cold-mould seal separating medium.

A Simple Analytical Model for Oil Production from Partially Fractured Reservoirs to Estimate Size of Finite Fracture Networks

Summary Most oil reservoirs are partially fractured, characterized by finite fracture networks (FFNs) in a sea of isolated fractures. It is necessary to determine size and shape of each FFN explicitly for reservoir simulation. FFN size is correlated with fracture connectivity, which is a function of fracture density, length, and angular scatter. Oil production from FFNs exhibits a long-term dual-porosity behavior. The initial fast rate (Phase I) represents depletion of matrix within FFN, and the subsequent gradual decline phase represents radial flow from the matrix outside the FFN perimeter. Thus, FFN size can be calculated from the cumulative oil production from Phase I, taking into account the pore volume, oil compressibility, and pressure decline. It is not always possible to identify the dual-porosity behavior by visual inspection. A mathematical model is needed to estimate FFN size. For this purpose, a set of three fundamental equations are derived for production rate, cumulative production, and pressure as a function of time. The model is a modified and simplified version of material balance equations with easy analytical solution. It is designed for fractured reservoirs with layer-bound fractures. Production is single-phase black oil under depletion drive. The analytical model was tested on four vertical wells. The unknown parameters such as FFN size, size of well drainage area, and fracture aperture are adjusted until an optimum fit to actual production data is obtained. FFN elliptical shape is estimated from average fracture strike and strike standard deviation. The results are validated by FFN size, fracture length, and aperture measurements from borehole images. The results are approximate but sufficient for preliminary mapping of FFNs with location and size and other critical attributes including fracture drainage area, matrix block size, fracture aperture, and permeability in partially fractured reservoirs.

Влияние масла черного тмина на различные звенья гемостаза крыс в условиях экзогенной тромбинемии

Black cumin oil has a rich phytochemical composition and is widely used as a dietary supplement for preventive purposes. However, there is a lack of scientific data on its effect on haemostasis. Thus, the purpose of this paper was to study the nature of the effect of the dietary supplement Ethiopian Black Cumin Oil on the platelet and coagulation components of the coagulation system under experimental thrombinemia. Materials and methods. The research involved 60 white non-inbred male rats. The following haemostasis parameters under exogenous thrombinemia were studied: prothrombin time, thrombin time, activated partial thromboplastin time, content of fibrinogen and soluble fibrin monomer complexes, antithrombin III activity, total platelet count and the ratio of different forms of platelets. Results. The research showed that pre-administration, in the course of 21 days, of black cumin oil to rats (experimental group) increases their tolerance to thrombin, limiting excessive platelet activation, development of thrombocytopenia and consumption coagulopathy compared with the control group. The data obtained during the experiment revealed a protective effect of oral administration of black cumin oil under provoked hypercoagulation stress. Сonsumption coagulopathy in the test group was less pronounced after 0.5 hours of experimental thrombinemia; after 1 hour, haemostasis parameters returned to baseline values at a faster rate compared to the control. The supposed mechanism behind this effect is the ability of the antioxidants in this dietary supplement to limit the processes of free radical oxidation: black cumin is a combined natural antioxidant rich in flavonoids, phenolic acids, tannins and terpene compounds. The results of the research indicate good prospects for further studies into the effect of the dietary supplement Ethiopian Black Cumin Oil on various components of haemostasis as a non-specific agent.

Laboratory and Theoretical investigations of Petroleum Reservoir Fluid Properties

Understanding the Pressure-Volume-Temperature (PVT) properties is very important to many kinds of petroleum determinations like calculations of reservoir fluid properties; expect the future performance, selection of enhanced oil recovery methods, and for production facilities design. Models for expecting reservoir fluid properties has been increased attention during last decade by knowing reservoir pressure and temperature, oil API gravity, and gas gravity. In general, PVT properties are obtained from laboratory experiments but in some cases In this study, complete PVT lab experiments were done and evaluated the most frequently used empirical black oil PVT correlations for application in the Middle East. Empirical PVT Correlations for the Middle East crude oil was compared as a function of commonly available PVT data. Correlations compared for: Bubble point pressure, solution gas oil ratio, oil formation volume factor, oil density, and oil viscosity. After evaluating the Empirical correlations, the crude sample was characterized using different EOS to arrive at one EOS model that accurately describes the PVT behavior of crude oil produced. The multi-sample characterization method is used to arrive at one consistent model for crude oil for the whole reservoir. The fluid sample is first analyzed for consistency to ensure that they are representative of oil produced, then it is used to obtain parameters for EOS model. The tuning procedure for the EOS is done systematically by matching the volumetric and phase behavior results with laboratory results. Results showed that some correlations give good results in PVT properties compared to the laboratory and can be used with Libyan oil, while some give a high percentage of error.

A comparative evaluation of proximate composition, elemental profiling and oil physicochemical properties of black cumin (Nigella sativa L.) seeds and argan (Argania spinosa L. Skeels) kernels

In this data article, proximate composition, elemental profiling of fruits and oil cakes and the physicochemical properties of the mechanically extracted oil of Moroccan black cumin and argan were compared. Oxidative stability was determined under accelerated aging conditions at 60°C for four months. Elemental profiling showed comparable values for nigella seeds, argan kernels and their oil cakes. The highest values of oil content (52%) and energy value (595.14 kcal/100 g) were found in argan kernels, the argan cake also showed its superiority in terms of moisture content (6.46%) and protein content (45.93%). The highest carbohydrate content (51.31%) was found in black cumin cake. Black cumin (cake and oil) can be considered as valuable sources for new multipurpose products for industrial, food and cosmetic use. Oil oxidation outcomes revealed sensitity of black cumin oil as compared to argan oil. Therefore, special care should be considered for its prolonged storage.

A step-by-step approach to creating and tuning PVT-models of reservoir hydrocarbon systems based on the state equation

The article is considering a new effective step-by-step approach to creating and tuning PVT-models of reservoir oil and reservoir gas condensate mixtures. The method is based on the reproducing of the results of field measurements and basic laboratory studies of representative samples in thermodynamic modeling using cubic three parameters equation of state. Tuning PVT-model is used for reliable modeling of PVT properties of reservoir fluids (reservoir oil and reservoir gas) in the design and monitoring of field development, calculation of multiphase flow in wells and field pipelines, as well as in basin modeling. Proposed approach makes possible to tune the PVT model with high accuracy of both reservoir oil and reservoir gas condensate system to experimental data using a step-by-step procedure, where at each step, by changing one of the parameters of the equation of state, one of the PVT properties of the hydrocarbon system is tuned. Algorithmization and automated application of this approach in specialized software products is possible. Proposed approach allows tune reservoir oil PVT-models on the main PVT-properties such as saturation pressure, FVF, STO density, gas-oil ratio of reservoir oil and dependencies of dynamic viscosity and compressibility on pressure at reservoir temperature as well as STO density. The tuned gas-condensate PVT-model precisely reproduces the key properties such as dew point pressure, initial condensate content in the reservoir gas, z-factor of the reservoir gas, gas-oil ratio, stable condensate density, drop down curve by the result of CVD-test. PVT-models created on the base of the proposed method, provide reliable information on the properties of a reservoir fluid in development of flow simulation both using a reservoir simulation compositional models and using pseudo models “black oil”. The method is illustrated by the example of creation of the adequate PVT-models of various regions of Russia reservoir oil and reservoir gas condensate mixtures.

Preparation of Black pepper (Piper nigrum L.) essential oil nanoparticles and its antitumor activity on triple negative breast cancer in vitro.

The active compounds isolated from Black pepper have anticancer effects, but the bioactivity of Black pepper essential oil (BP-EO) is rarely studied. BP-EO has poor stability and a suitable dose form should be prepared for in vivo delivery. Triple negative breast cancer (TNBC) has attracted more and more attention due to its high mitotic index, high metastasis rate and poor prognosis. In this study, the composition of BP-EO was analyzed by gas chromatography-mass spectrometry (GC-MS), and nanoparticles (NPs) loaded with BP-EO were prepared by nanoprecipitation method using Eudragit L100 as a carrier. We investigated the preparation, characterization, stability and in vitro release of nanoparticles. MTT assay, cell wound healing, Transwell invasion assay and Western blot were used to study the anti-tumor effect and mechanism of MDA-MB-231 cells. The GC-MS analysis identified a total of 33 compounds among which alkenes account for 63.55%. The prepared BP-EO NPs exhibited nanoscale morphology, good stability and pH-responsive and sustained release character which is suitable for in vivo delivery. BP-EO NPs significantly inhibited the proliferation, migration and invasion of MDA-MB-231 cells. Furthermore, BP-EO NPs significantly inhibited the expressions of Wnt and β-catenin and significantly activated the expression of GSK-3β in MDA-MB-231 cells. Therefore, BP-EO NPs prepared in this study provide a new effective strategy for the treatment of TNBC. PRACTICAL APPLICATIONS: Black pepper is rich in essential oil and has excellent antioxidant and antibacterial activities. However, the anti-tumor activity of BP-EO has not been studied. In this study, we found that BP-EO has excellent anticancer activity. To achieve effective encapsulation of black pepper essential oil and an excellent anti-triple negative breast cancer activity, nanoparticles loaded with BP-EO were prepared using Eudragit L100 as the carrier by the nanoprecipitation method. The in vitro study revealed that BP-EO NPs inhibited proliferation, migration and invasion of MDA-MB-231 cells via inhibiting the Wnt/β-Catenin signaling pathway. This study provides new ideas and innovations for the treatment of invasive triple negative breast cancer in the future. At the same time, we will further reveal the application potential, pharmacokinetic characteristics and precise mechanism of BP-EO NPs in vivo in subsequent studies.

Parallel multi-stage preconditioners with adaptive setup for the black oil model

The black oil model is widely used to describe multiphase porous media flow in the petroleum industry. The fully implicit method features strong stability and weak constraints on timestep sizes; hence, it is commonly used in current mainstream commercial reservoir simulators. In this paper, a Constrained Pressure Residual (CPR) preconditioner with an adaptive “setup phase” is developed to improve the parallel efficiency of a petroleum reservoir simulation. Furthermore, we propose a multi-color Gauss–Seidel (GS) algorithm for the algebraic multigrid method based on the coefficient matrix of strong connections. Numerical experiments show that the proposed preconditioner can improve the parallel performance for both OpenMP and Compute Unified Device Architecture (CUDA) implements. Moreover, the proposed algorithm yields good parallel speedup as well as the same convergence behavior as the corresponding single-thread algorithm. In particular, for a three-phase benchmark problem (about 3.28 million degrees of freedom), the parallel speedup of the OpenMP version is over 6.5 with 16 threads, and the CUDA version reaches more than 9.5.

Studies in instant water disinfection using natural oils

The present research reveals an instant and simple process for drinking water treatment by employing specific natural oils having antimicrobial properties to ensure complete elimination of harmful bacteria. The disinfection was studied for two different model bacteria, Gram-negative E. coli and Gram-positive, S. aureus. Seven natural oils, ajwain, thyme, oregano, peppermint, harsingar, cinnamon leaf and black pepper oil were evaluated and were found to yield 100% water disinfection within 1 min except for harsingar and black pepper oil. The process was also effective for the instant and 100% disinfection of real well water. The methodology for altering zeta potential, to an extent of 130%, for instant disinfection in drinking water treatment helps in selecting natural oils. Molecular docking studies indicated natural oils action as potential inhibitors of bacterial DNA gyrase. The studies indicate one of the lowest operating costs comparable to conventional chlorination. The simple methodology not requiring complex equipment has the potential to provide many options for implementations- from portability, household application to large scale water treatment plants.

Combined Ramipril and Black Seed Oil Dosage Forms Using Bioactive Self-Nanoemulsifying Drug Delivery Systems (BIO-SNEDDSs).

Purpose: Ramipril (RMP)—an angiotensin-converting enzyme (ACE) inhibitor—and thymoquinone (THQ) suffer from poor oral bioavailability. Developing a combined liquid SNEDDS that comprises RMP and black seed oil (as a natural source of THQ) could lead to several formulations and therapeutic benefits. Methods: The present study involved comprehensive optimization of RMP/THQ liquid SNEDDS using self-emulsification assessment, equilibrium solubility studies, droplet size analysis, and experimentally designed phase diagrams. In addition, the optimized RMP/THQ SNEDDS was evaluated against pure RMP, pure THQ, and the combined pure RMP + RMP-free SNEDDS (capsule-in-capsule) dosage form via in vitro dissolution studies. Results: The phase diagram study revealed that black seed oil (BSO) showed enhanced self-emulsification efficiency with the cosolvent (Transcutol P) and hydrogenated castor oil. The phase diagram studies also revealed that the optimized formulation BSO/TCP/HCO-30 (32.25/27.75/40 % w/w) showed high apparent solubility of RMP (25.5 mg/g), good THQ content (2.7 mg/g), and nanometric (51 nm) droplet size. The in-vitro dissolution studies revealed that the optimized drug-loaded SNEDDS showed good release of RMP and THQ (up to 86% and 89%, respectively). Similarly, the isolation between RMP and SNEDDS (pure RMP + RMP-free SNEDDS) using capsule-in-capsule technology showed >84% RMP release and >82% THQ release. Conclusions: The combined pure RMP + RMP-free SNEDDS (containing black seed oil) could be a potential dosage form combining the solubilization benefits of SNEDDSs, enhancing the release of RMP/THQ along with enhancing RMP stability through its isolation from lipid-based excipients during storage.

FORMULATION AND STABILITY STUDY OF BLACK CUMIN (NIGELLA SATIVA L.) SEED OIL EMULSION USING SUCROSE PALMITATE AS EMULSIFIER

Objective: An emulsion of black cumin seed oil was developed using an orally safe surfactant, sucrose palmitate, to make it more comfortable to consume. Methods: The emulsion was made using a 3% concentration of sucrose palmitate to emulsify 5% (F1) and 7.5% (F2) black cumin seed oil to the developed stable emulsion. The hedonic test was applied to 30 panelists, showing the accepted formulation. Results: The pH value of each formulation degraded during 12 w of storage. The formula of 5% oil (F1) has better physical stability, and its bioactive component, Thymoquinone, showed a slight degradation on the first day. But it showed a rapid degradation after 60 d of storage due to its instability in a solution. The F1 formula (mean = 3.1667) is more preferred than the F2 formula (mean = 3) of the 1-5 hedonic scale, with the significance score (p) valued less than 0.05 and considered to be significantly different from its original form. Conclusion: The emulsion of black cumin oil can be developed and more comfortable to consume.

Microbiome analysis reveals the effects of black soldier fly oil on gut microbiota in pigeon.

The gut microbiota plays a vital roles in poultry physiology, immunity and metabolism. Black soldier fly oil is known to have a positive effect on the gut microbiota. However, the specific effect of black soldier fly oil on the composition and structure of the gut microbiota of the pigeon is unknown. In this experiment, 16S rDNA high-throughput sequencing was performed to study the effect of different doses of black soldier fly oil on the changes of pigeon intestinal microbes. Results indicated that the different doses of black soldier fly oil had no effect on the gut microbial diversity of the pigeon. Although the dominant phyla (Proteobacteria, Firmicutes, Bacteroidetes, and Actinobacteria) and genus (uncultured_bacterium_f_Lachnospiraceae and Desulfovibrio) in control group and experimental group with different doses were the same, the abundances of some beneficial bacteria (Megasphaera, Intestinimonas, Prevotella_9, Lachnospiraceae_UCG-001, Faecalibacterium, Coprococcus_2, Parabacteroides, Megasphaera, Leuconostoc, Prevotellaceae_UCG-001, Lactococcus, Ruminococcaceae_UCG-014, and Coprococcus_2) increased significantly as the concentration of black soldier fly oil increased. Taken together, this study indicated that black soldier fly oil supplementation could improve gut microbial composition and structure by increasing the proportions of beneficial bacteria. Notably, this is the first report on the effects of black soldier fly oil on the gut microbiota of pigeon, which contribute to understanding the positive effects of black soldier fly oil from the gut microbial perspective.

Implementation of the decision making along with analytic hierarchy process (AHP) approaches in the assessment of the petroleum products cost based on the statical model

In this study, the investigation of the decision-making strategy was used to select the alternative that was finally adopted in the crude oil refining process. This strategy was used to select the option that was ultimately implemented in the process. The Doura industrial refinery was the source of the information that was acquired for the analysis. The super decision software was applied in order to carry out an examination of the PDS components. After going through the process of refining, one can get the items on the following list: There are five main types of petroleum products, and they are: gasoline, gas oil, liquid gas, black oil, and white oil. Gasoline is the most common type of petroleum product. In order for the parameters to be optimally accommodated by the solution that is finally decided to be the most practical one, the analytic hierarchy process, also known as AHP, technique has been applied. This has been done in conjunction with the parameter determination system, or PDS. This has been done in order to reach the maximum potential level of productivity in the most efficient manner. As a result of the fact that this was the circumstance, a probe into the preliminary phase of the project was carried out, which in the end resulted in the expenditure of a grand total of 3969463 USD. This was determined by taking into account the costs of running the firm in addition to the prices of the raw materials that were utilized in the production process. In addition, the output of the refining process was not only dependent on the price and quantity of the product, but also on the amount of product that was actually sold. This meant that the cost and quantity of the product were not the only factors that determined the output. In order to determine what should be done during the process of making an estimate of what should be done in order to arrive at the response that was going to be the most advantageous taking everything into consideration, a mathematical model was applied as part of the process.

Synergistic Lubrication Effect between Oxidized Black Phosphorus and Oil Molecules Triggers Superlubricity.

Oxidized black phosphorus (BP) has been demonstrated as a promising oil-based nanoadditive because of its superior friction-reducing capability. However, the synergistic lubrication effect between oxidized BP and oil at the molecular level dominating the friction properties remains unclear. In this Letter, the synergistic lubrication effect between oxidized BP and two typical oil molecules (nonane and nonanoic acid) was explored with an atomic force microscope. The superlubricity of oxidized BP with an ultralow friction coefficient of 0.006 was achieved in the nonanoic acid environment, exhibiting a 96% reduction compared with that in the nonane environment. There was a confined nonanoic acid layer in the contact zone with a tilt angle of 35° because of the hydrogen bonding interaction, contributing to the superlubricity. This observation sheds light on the exploration of the lubrication mechanism of oxidized BP as a nanoadditive in oil, which reveals the considerable implications for the design of high-performance lubrication system.

Effects of black soldier fly larvae oil on growth performance, immunity and antioxidant capacity, and intestinal function and microbiota of broilers

Black soldier fly larvae (BSFL) are developing into a possible source of food since they can generate energy and have a good amino acid profile. This study looked at whether broiler diets may be supplemented with black soldier fly larvae oil (BSO). These groups of broilers were fed diets that replaced the soybean oil (SO) with varying amounts of BSO: 0%, 25% (BSO25), 50% (BSO50), 75% (BSO75), and 100% (BSO100). Levels of aminotransferase, total protein, albumin, glutathione peroxidase, total superoxide dismutase, and blood urea nitrogen were all shown to have altered considerably. In addition, the ileal villus height, doudenal crypt depth, and the proportion of doudenal villus height to crypt depth were altered. Finally, compared to the SO group, there was a substantial increase in the mRNA levels of IL-2, tumor necrosis factor α, mucin 2, junctional adhesion molecule 2, and zonula occludens-2. It is interesting to note that the community richness of the gut microbiota and the abundance of Cyanobacteria and Proteobacteria were significantly altered in comparison with the SO group. Our findings suggest that BSO can replace SO in the formulation of broiler diets, with 50% BSO being the best option out of the BSO concentrations examined.

Effects of the Chemical Composition on the Antioxidant and Sensory Characteristics and Oxidative Stability of Cold-Pressed Black Cumin Oils.

The antioxidant capacity (AC); amounts of tocopherols, sterols, and polycyclic aromatic hydrocarbons; oxidative parameters; fatty acid composition (FAC); and sensory quality of cold-pressed black cumin oils (CPBCOs) available on the Polish market were analyzed and compared. The AC levels of the CPBCO samples were determined using four assays, namely 2,2-diphenyl-1-picrylhydrazyl (DPPH = 226.8–790.1 μmol TE/100 g), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS = 385.9–1465.0 μmol TE/100 g), cupric-reducing antioxidant capacity (CUPRAC = 975.3–19,823.3 μmol TE/100 g), and Folin–Ciocalteu assays (FC = 168.1–643.7 μmol TE/100 g). The FAC scores were typical for black cumin oil, except for the sample CPBCO4, which had a higher content of α-linolenic acid (C18:3 = 23.33%), pointing to possible oil adulteration. Additionally, the concentrations of total sterols (TSC = 372 mg/100 g) and tocopherols (TTC = 42.3 mg/100 g) in this sample were higher than those for other investigated oils (TSC = 159–222 mg/100 g, TTC = 1.9–10.4 mg/100 g respectively). The oxidative stability levels (IP = 8.21–37.34 h), peroxide values (PV = 21.36–123.77 meq O2/kg), acid values (AV = 6.40–22.02 mg KOH/kg), and the sums of four specific polycyclic aromatic hydrocarbons (∑4PAHs = 4.48–46.68 μg/kg) in the studied samples differed significantly (p < 0.05). A sensory lexicon including 12 attributes was developed and applied for the sensory evaluation of oils using a quantitative descriptive analysis (QDA).
