Utilization of opium poppy seed oil for biodiesel production: A parametric characterization and statistical optimization

Consuming traditional petroleum-derived diesel fuel has long been associated with issues such as the depletion of natural energy resources. To solve these challenges, an alternate source like as biodiesel is an appealing option. Seed oils have long been recognized as an abundant and diverse source of biodiesel. In this study, poppy seed oil from the poppy (Papaver somniferum) was investigated for biodiesel production. Poppy seed biodiesel was generated and refined using acid-pretreated esterification with sulphuric acid prior to transesterification, as well as single-step alkaline catalyzed transesterification with methanol and potassium hydroxide. Finally, the percentage yield was compared. Using Statistica, the Box-Behnken design was applied to optimize process variables like time, temperature, catalyst concentration, and methanol-oil ratio to produce maximum yield. The relationship of process variables was also shown with the help of the Response Surface Methodology. A maximum yield of 94.87 % was obtained at optimized conditions, i.e., 90min reaction time, 60 °C of temperature, 0.25 mg of catalyst concentration, and 3v/v% alcohol-oil ratio. The fuel properties of biodiesel produced, such as acid value, moisture content, saponification value, iodine value, specific gravity, percentage of free fatty acids, refractive index, viscosity, boiling point, and peroxide value, were measured and compared with the American Society for Testing and Materials (ASTM) D6751 and European Standards (EN) 14214. Further results were studied and discussed using Fourier Transfer Infrared (FTIR) analysis, which showed maximum similarity of raw material to formed biodiesel. Gas Chromatography-Mass Spectrometry (GC-MS) analysis was performed to identify and quantify various fatty acid methyl esters. The results obtained were in accordance with various international standards for biodiesel fuel. Thus, poppy seeds can be used to obtain biodiesel.

Effect of PKD1L1 Mutation on its Interaction with PKD2 to Cause Situs Inversus Totalis

Situs inversus totalis (SIT) is a rare homozygous recessive disease caused by the mutation in PKD1L1, which is required for normal interaction with PKD2 and leads to different complications such as respiratory disorders, brain disorders and even obesity. The present study was designed to find out the mutational effect on the binding of PKD2 with mutated PKD1L1, which leads to SIT. The three-dimensional (3D) structure of wild type and mutated PKD1L1 was predicted with > 90% confidence using different online tools. The different online tools that were employed were SWISS-MODEL, Phyre2 (normal & intensive) and i-TASSER. To compute the physiochemical properties of PKD1L1 (wild & mutated) and PKD2 in silico approaches were employed using the ExPASy ProtParam tool. Physicochemical properties such as molecular weight, isoelectric point, the total number of negatively and positively charged residues, extinction coefficient, half-life, instability and aliphatic index, grand average of hydropathicity, and amino acid percentage were calculated. A lot of variability was observed in these parameters among PKD1L1 and PKD2, which accounted for diversification in their functional properties. The theoretical pI points showed that PKD1L1 (whole) is more basic with 6.64 pI compared to its first chain TOPO_DOM (amino acids from 1–1748) has a pI of 5.62 which means it is basic while PKD2 have the lowest pI point of 5.34. Docking was performed using the PatchDock and ClusPro online tools.

Fecal short-chain fatty acids level and pediatric relapsing nephrotic syndrome

Background The gut microbiota has a potential role in the development of nephrotic syndrome. Fecal short-chain fatty acid (SCFA) levels are representative of gut microbiota activity. Objective To assess for potential associations of fecal short-chain fatty acid levels in pediatric relapsing nephrotic syndrome. Methods This cross-sectional study was done on patients at the Pediatric Nephrology Subdivision of Prof. Dr. R.D. Kandou General Hospital, a referral hospital in Manado, Indonesia. Subjects were 25 patients aged less than 18 years with nephrotic syndrome (NS). We compared the levels of fecal acetic acid, propionic acid, butyric acid percentage, absolute butyric acid, and total short-chain fatty acid between children with relapsing and non-relapsing NS. A receiver operating characteristic (ROC) curve analysis was conducted to determine the significant SCFA cut-off level to diagnose NS. Results Comparison of fecal SCFAs between relapsing and non-relapsing NS groups showed significantly lower butyric acid percentages, absolute butyric acid level, and total SCFAs levels in the relapsing NS group, but not in acetic acid or propionic acid levels. Further multivariate analysis did not show a significant difference in total SCFA levels between relapsing and non-relapsing NS. Absolute butyric acid level had the strongest association with relapsing NS, with the highest predictive score. The absolute butyric acid cut-off value of 0.85 mg/mL had a high sensitivity (90%) and high specificity (93.3%) for predicting relapsing nephrotic syndrome. Conclusion Fecal acetic acid, propionic acid, and total short-chain fatty acid in stool are not associated with relapsing NS in children. However, fecal butyric acid measurements are inversely associated with relapsing NS.

Unveiling the oxidative stability, phytochemical richness, and nutritional integrity of cold-pressed Linum usitatissimum oil under UV exposure

This study examines the effect of UV irradiation on the oxidation stability of Linum usitatissimum oil, presenting possible changes in the phytochemical profile due to photo-oxidation. GC–MS analysis of the oils identified 11 fatty acid compounds with a high percentage of unsaturated fatty acids, the most important of which is α-linolenic acid (ALA), known as omega-3 (48.88 %), also significant profiles of phytosterol and tcocopherol isomers rich in β-Sitosterol and γ-tocopherols respectively. As well as physicochemical properties such as free fatty acids (FFA %), peroxide value (PV) and iodine value (IV), and nutritional indexes that determine the significant changes observed during the oxidation process, the most important of which is the progressive increase in acidity, peroxide, conjugated dienes and trienes and degrees of unsaturation over 8 h of UV exposure. High levels of carotenoids and phenolic compounds (TPC) protect and enhance oil quality in the face of irradiation, so a significantly small difference is observed between irradiated and non-irradiated oil during photo-oxidation.

CAPZB mRNA is a novel biomarker for cervical high-grade squamous lesions

This study aimed to evaluate the potential of capping protein (actin filament) muscle Z-line subunit β (CAPZB) messenger ribonucleic acid (mRNA) levels as a biomarker for distinguishing low-grade squamous intraepithelial lesions of the cervix (LSIL) from high-grade squamous intraepithelial lesions of the cervix (HSIL). We collected a total of 166 cervical exfoliated cells and divided them into five groups based on histopathological results. Each sample was divided into two portions, one for fluorescence in situ hybridization (FISH) detection and the other for bisulfite sequencing polymerase chain reaction (BSP) detection. We found that FISH detection of CAPZB mRNA mean fluorescence intensity (MFI) and BSP detection of CAPZB deoxyribonucleic acid (DNA) percentage of methylation rate (PMR) performed as biomarkers for distinguishing HSIL from LSIL, with an area under the receiver operating characteristic curve (AUC), sensitivity, specificity and cut-off value of 0.893, 81.25%, 80.39% and 0.616, 0.794, 64.06%, 81.37% and 0.454, respectively. Furthermore, FISH detection of CAPZB mRNA exhibited a greater AUC (0.893) for the detection of HSIL than the CAPZB DNA methylation method (0.794), indicating the CAPZB mRNA levels can be used as a biomarker for assessing cervical lesions.

Influence of kaempferol against garri meal tainted with vacuum gas oil induced nephro- and neurotoxicity

The present study investigated the defensive effect of kaempferol in the tissues of Wistar rats fed with vacuum gas oil polluted garri diet. The rats (30) were grouped into six (n = 5): Group 1: Control: Fried garri normal diet (FGND). Group 2 and 3 were given FGND and treated with 50 and 100 mg/kg b. wt of kaempferol. Group 4: Fried garri diet with vacuum gas oil (FGD-VGO) only. Group 5 and 6 were given FGD-VGO then treated with 50 and 100 mg/kg b. wt. of kaempferol. The rats were euthanized using carbon dioxide after experimental period of 28 days. The tissues (kidney and brain) were excised for biochemical assays. The results indicated a significant decrease in antioxidant markers (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-s-transferase, GST), Na+/K+-ATPase, percentage of fragmented deoxyribonucleic acid (DNA) and increase malondialdehyde (MDA) in the tissues of rats in group 4 compared to the other groups. However, treatment with kaempferol significantly decreased MDA level and increased antioxidant markers in the tissues of rats fed FGD-VGO. In conclusion, the data obtained may point out to kaempferol playing a crucial role as an antioxidant against garri meal tainted with vacuum gas oil in Wistar rats.

Effects of Intermittent and Chronic Hypoxia on Fish Size and Nutrient Metabolism in Tiger Puffer (Takifugu rubripes).

Intermittent and chronic hypoxia are common stresses to marine fish, but the different responses of fish to intermittent and chronic hypoxia have not been well-known. In this study, tiger puffers were farmed in normoxia conditions (NO, 6.5 ± 0.5 mg/L), intermittent hypoxia (IH, 6.5 ± 0.5 mg/L in the day and 3.5 ± 0.5 mg/L in the night), or choric hypoxia (CH, 3.5 ± 0.5 mg/L) conditions for 4 weeks, after which the growth, nutrient metabolism and three hifα isoforms expression were measured. Both intermittent and chronic hypoxia decreased the fish growth and visceral weight but increased the feed conversion ratio and blood hemoglobin content. Chronic hypoxia but not intermittent hypoxia promoted protein synthesis and whole-fish protein content by activating mtor gene expression and promoted the glycolysis pathway by activating gene expression of hif1α and hif2α. Intermittent hypoxia but not chronic hypoxia decreased the hepatic lipid synthesis by inhibiting fasn and srebf1 gene expression. Meanwhile, intermittent hypoxia reduced the monounsaturated fatty acid content but increased the n-3 polyunsaturated fatty acids percentage. The results of this study clarified the adaptive mechanism of tiger puffer to intermittent and chronic hypoxia, which provides important information about mechanisms of hypoxia adaption in fish.

Production of Single Cell Protein (SCP) from the Peel Waste of Pea, Potato, and Banana by Aspergillus Flavus NRRL 21882 as an Efficient Organic Poultry Supplement.

Food protein deficit has become a major issue worldwide, particularly in underdeveloped countries. Scientists are searching for a variety of less expensive solutions to this issue. One of these less expensive methods is to create single cell protein as a substrate from leftover fruit and vegetable waste, which is typically thrown away. In this regard, the fungal strain Aspergillus flavus (NRRL 21882) was used for the synthesis of SCP (single cell protein) from the waste of banana, potato, and pea. In this manner, 30 samples were collected from the whole substrate with a share of 10 samples each from banana, potato, and pea peels, which were in turn dried and powdered finely. The fermentation process was done by the process of solid state fermentation. Aspergillus flavus (NRRL 21882) generated the highest percentage, i.e. 60.67%, of crude protein from the pea peels. The composition of amino acids in crude proteins was also investigated. The findings demonstrated that the highest percentage of aspartic acid (13.34 ± 0.80%) and glutamic acid (14.92 ± 0.69%) was found in A. flavus single cell protein produced from pea peels. Soybean was supplemented with single cell protein in the boilers' diet. Compared to all treated groups, there was a substantial (p ≤ 0.05) increase in the level of antibody titer against the Newcastle disease vaccine. The supplementation of single cell protein with soybean meal had no effect on the levels of liver enzymes. The liver enzymes found in all four groups (A, B, C, and D) were within normal limits. None of the examined groups experienced any change in the feed conversion ratio, with all groups exhibiting an average FCR of 1.6. The current study concludes that broiler health and immunity is increased by supplementing poultry feed with single cell protein.

Enhanced wound healing activity of naturally derived Lagenaria siceraria seed oil binary nanoethosomal gel: formulation, characterization, in vitro/in vivo efficiency

BackgroundThe present study aims to enhance the wound healing potential of the seed oil (SO) of Lagenaria siceraria (Egyptian cultivar) via the preparation of SO-loaded binary nanoethosomal (SO-BNE) gels. SO-BNEs were prepared using 23 factorial design, characterized for vesicle size, zeta potential, polydispersity index, linoleic and oleic acid EE% for ensuring improved skin permeability. The L. siceraria SO, optimized SO-BNE gels (0.5% and 5%) and Mebo® were topically applied in full-thickness wounded rat model twice daily for 10 days.ResultsIn the SO-BNE gel groups, the normal appearance of the skin architecture and structure of the dermis was revealed. In addition, the levels of NRF2, TGF-β1 and FOXO1, collagen type I, SMA-α and MIP2 were significantly elevated. The wound healing potential of SO-BNE gels was proposed to be via suppression of oxidative stress and stimulation of skin regeneration biomarkers. Furthermore, the SO screening through GC/MS unveiled high percentages of unsaturated fatty acids. SO was also found to be nontoxic to human skin fibroblast cells; enhanced viability and migration rates at concentration of 50 g/mL by 99.76% and 75.9%, respectively.ConclusionThese findings demonstrate that the Lagenaria siceraria SO-loaded BNE gels represent a promising delivery for wound healing with enhanced release and bioavailability.

Quantitative genetic analysis indicate non-heritability of major fatty acid in the muscle of Chinese mitten crab (Eriocheir sinensis)

The Chinese mitten crab (Eriocheir sinensis) is a commercially important aquaculture species, and crab meat generally has the high percentage of long-chain polyunsaturated fatty acids (LC-PUFAs) in the total fatty acids, which contributes the unique flavor and high nutrition value for adult crab. Muscle is the largest edible tissue in crustaceans, containing a variety of fatty acids, and understanding the genetic parameters of fatty acids in the meat of E. sinensis would be useful for the aquaculture of this species. This study investigated the heritability, genetic and phenotypic correlations of major fatty acids in the muscle of E. sinensis. Progeny from 25 full-sib families were reared under a common environment until they reached market size, and 429 mature crabs were selected for analysis. The results showed that the heritabilities of most fatty acids were low ranged from 0.01 (n-3PUFA) to 0.21 (MUFA), but the high heritabilities were recorded for C20:3n3 and C20:3n6 with values of 0.99 and 0.32, respectively. Furthermore, the strongest positive genetic correlations were found between C20:5n3 and C22:6n3(0.99), n-3PUFA(0.99), and PUFA and LC- PUFAs (0.99), n-3PUFA(0.99), whereas the strongest phenotype correlation was found between C20:5n3 and n-3 PUFA (0.96); C20:3n6 showed a significant negative genetic correlation with C20:3n3(−0.86) and C18:0 (−0.98), whereas C20:3n6 showed significant negative phenotypic correlation with C20:3n3(−0.14), C20:5n3(−0.15) and C22:6n3(−0.18). In conclusion, the percentages of major fatty acids, particularly C20:5n3, C22: 5n3 and C20:4n6, in E. sinensis muscle have very low heritabilities, suggesting that these fatty acids contents/composition in the muscle are ineffective targets for the selective breeding programs of E. sinensis.

Basic nutrients and UPLC- ZenoTOF-MS/MS based lipomics analysis of Chenopodium quinoa Willd. varieties

This study conducted a comparison of the nutritional content and lipid composition of five different varieties of quinoa (QL-1, SJ-1, SJ-2, KL-1, and KL-2) from Qinghai Province, China. Each of the five varieties exhibited varying levels of essential nutrients, including crude protein, dietary fiber, and crude fat. The QL-1 variety has the highest concentration of phytic acid, measuring 1.66 g/100 g. A non-targeted lipomics analysis discovered a total of 16 lipid categories and 383 individual lipids in quinoa. Out of the several substances, glyceride had the highest concentration, exceeding 70%, with phospholipids coming next. The percentage of fatty acids and fatty acid esters was between 5 and 11%. The glycerides in all five kinds exhibited a similar composition, with unsaturated glycerides constituting over 99% of the total glycerides. Phospholipids constituted over 11% of the overall lipid content, with lecithin comprising more than 80% and cephalin ranging from 16.70 to 18.61%. The results establish a solid basis for the utilization of quinoa in processing, particularly in lipid processing.Graphical

Ultrasound-assisted extraction of bioactive compounds from Moringa oleifera leaves for beef patties preservation: Antioxidant and inhibitory activities, half-life, and sensory attributes.

This study aims to examine employing ultrasound-assisted extraction of bioactive components from Moringa oleifera leaves and apply them in beef patties preservation, as well as antioxidant and inhibitory activities and sensory qualities. The study included studying the chemical content and minerals of the M. oleifera leaves, preparation of aqueous and alcoholic extracts using an ultrasound device, then exploring the extraction yield. The results proved that the extraction yield by ultrasound using ethanol at 80% was the highest, reaching 19.22%. The total phenols in the ultrasonic extract with moringa leaves aqueous extract (AMEUS) amounted to 120,755 mg/mL. Since the AMEUS exhibited the highest value of 68.308 mg/mL calic acid - eight phenolic compounds discovered by HPLC - the total content of flavonoids was also calculated. The inhibitory and antioxidant effects of moringa leaf extracts are well documented. We monitored the changes in chemical indicators, such as the value of peroxide and thiobarbituric acid, as well as the percentage of free fatty acids and physical characteristics, such as water-carrying capacity, pH, and pigments, for storage periods 0, 4, 8, and 12 days after adding AMEUS to beef patties at a concentration of 0.5%. The patties were kept under refrigeration at 4 ± 1°C during this time. The values of peroxide number, thiobarbituric acid, free fatty acid, and metmyoglobin pigment were decreased in the beef patties treated with the AMEUS. However, they increased continuously during the cryopreservation period, and there was a significant increase in water-holding capacity (WHC) when the beef patties were treated with AMEUS. The results also showed that adding AMEUS to beef patties improved their qualitative characteristics.

Assessment of 5-Hydroxymethylfurfural in Food Matrix by an Innovative Spectrophotometric Assay.

Foods contaminants pose a challenge for food producers and consumers. Due to its spontaneous formation during heating and storage, hydroxymethylfurfural (HMF) is a prevalent contaminant in foods rich in carbohydrates and proteins. Colorimetric assays, such as the Seliwanoff test, offer a rapid and cost-effective method for HMF quantification but require careful optimization to ensure accuracy. We addressed potential interference in the Seliwanoff assay by systematically evaluating parameters like incubation time, temperature, and resorcinol or hydrochloric acid concentration, as well as the presence of interfering carbohydrates. Samples were analyzed using a UV-Vis spectrophotometer in scan mode, and data obtained were validated using HPLC, which also enabled quantification of unreacted HMF for assessing the protocol's accuracy. Incubation time and hydrochloric acid percentage positively influenced the colorimetric assay, while the opposite effect was observed with the increase in resorcinol concentration. Interference from carbohydrates was eliminated by reducing the acid content in the working reagent. HPLC analyses corroborated the spectrophotometer data and confirmed the efficacy of the proposed method. The average HMF content in balsamic vinegar samples was 1.97 ± 0.94 mg/mL. Spectrophotometric approaches demonstrated to efficiently determine HMF in complex food matrices. The HMF levels detected in balsamic vinegars significantly exceeded the maximum limits established for honey. This finding underscores the urgent need for regulations that restrict contaminant levels in various food products.

A Review of Cholesterol's Dual Impact: Human Health and Environmental Consequences

Abstract Indiscriminate consumption of fatty foods especially those with higher percentage of saturated fatty acids in and around the world is likely to be in excesses in few years to come. This is particularly so owing to man detrimental eating habits. And this portends a potential risk for coronary heart diseases among unsuspecting consumers. Although man has the enzymatic capacity to convert excess fatty acids to harmless substrates within the body system, but there occur serious pressure on such functions when they are in excesses of the normal daily body requirement. The impact of heavily rich fat meals to the large supply of total fats and its saturated fatty acids derivatives in the human system has been largely traced to dietary intake of lipid rich diets. Their consequential effect over time can damage arteries, contribute to heart disease, and even stroke among unsuspecting consumers. Incidentally this has been traced to cholesterol (lipoprotein), a waxy substance that the body requires to perform certain critical functions including digestion, circulation, and growth and even the nervous system regulation. There are two distinct forms are known these lipoproteins; high density and Low density lipoproteins. Even though both are essential, the excessive intake of the low-density lipoprotein (LDL) is dangerous could trigger certain cardiovascular diseases and even death due to its excessive accumulation in the body. In spite of these foregoing however, they plays very critical roles in the life of virtually all living organisms including man. Therefore it harps on the study for a comprehensive review about the concept and dispels the misinformation about the significance and implication of effects of both saturated and unsaturated fatty acids as probable precursor for certain cardiovascular ailments. Little wonder that some conscious individuals are cautious in choosing their meals owing to this trepidation. It therefore becomes imperative to undertake a study on related works with a view to giving suitable medical information to arm individuals with reliable data towards the trend.

Novel insights from agricultural waste to acetic acid through regulated high-solids anaerobic digestion: Focus on the key microbial communities

Acetic acid (HAc) is an essential intermediate for improving the efficiency of biogas production in anaerobic digestion (AD) or for the production of liquid chemicals. The relationships between the mechanisms and microbial contributions of targeted regulation of HAc production in high-solids AD remains unclear. This study represents a breakthrough in revealing the mechanism of pH directed regulation of HAc production and microbial interactions. The regulation of the initial spray pH effectively improved the substrate hydrolysis rate and increased the concentration of HAc, with an average HAc percentage of total organic acids was 66.20 %. Microecological analysis revealed that rare species played a vital role in acidification, with all key acetogenic microbes identified as rare species. Additionally, the construction of a bacterial–environmental factor co-occurrence network revealed that lowering the initial spray pH enhanced the synergistic interactions among bacterial communities, and proportion of positive interactions among bacteria was 82.23 %. The gene abundance of key enzymes in the acetate-type metabolic pathway dominated in the acidogenesis phase. Furthermore, a regression model was established between the HAc indicator microbe (Acinetobacter) and HAc yields. Overall, the results of this study indicate that pH regulation plays an important role in strengthening the production of HAc and rare species significantly contributed to HAc production.

Morpho-physiological and biochemical characterization of Kinnow (Citrus reticulata) in response to canker pathogens (Xanthomonas axonopodis pv. citri)

Fruits play an important role in human life on our planet, since they supply a variety of essential services. One of the paramount crops in Pakistan is Citrus reticulata (Kinnow), which plays a vital role in the country's economy. The citrus crops are confronted with various challenges such as fungi, bacteria, nematodes, and viruses, all of which have adverse effects on the quality and yield of the fruits. Citrus canker, in particular, stands as the most fatal disease, affecting numerous citrus species worldwide, inflicting devastating consequences. The objective of this study was to evaluate the impact of citrus canker on the morphology, physiology of leaves, and the quality of citrus fruits. The research was conducted in four major citrus-producing tehsils of the Sargodha district. The study found significant differences in morphological and physiological traits between healthy fruits and those infected with citrus canker. Healthy fruits exhibited higher values in fruit weight (FW) of 149.02 g, peel thickness (PT) of 3.76 g, rag weight (RW) of 35.95 g, leaf area (LA) of 22.49 cm2, and juice weight compared to the citrus canker-infected fruits. The significant variations in fruit weight, juice weight, chlorophyll content, vitamin C content were present between healthy and diseased fruits and leaves. A biochemical study revealed that healthy fruits had greater levels of total soluble solids (TSS), TSS-acid ratio, vitamin C, and reducing power (RP), but citrus canker-infected fruits had a higher acidity percentage. The significant decreases in important morphological and physicochemical characteristics, emphasizing the necessity for immediate disease control techniques to safeguard the citrus sector and maintain food security.

Purpose This study aims to realize the multipurpose use of inorganic materials in adsorption treatment of pigment wastewater and preparation of core-modified Color Index Pigment Red 57:1 (C.I. Pigment Red 57:1, PR 57:1). Design/methodology/approach In this paper, the inorganic materials (sepiolite and SiO2·nH2O) were used in both PR 57:1 production wastewater treatment and its core-modification. The inorganic material firstly adsorbed 3-hydroxy-2-naphthoic acid (bon acid) in the pigment wastewater to reduce chemical oxygen demand. Then, the inorganic material adsorbed with bon acid was reused to prepare core-modified PR 57:1. Findings In the pigment wastewater adsorption experiment, it was found that under pH = 3, the adsorption percentage of bon acid by inorganic material can reached up to 46.00%. The pigment characterization results showed that the core-modified PR 57:1 had a core-shell structure. Under UV light irradiation for 1 h, the core-modified PR 57:1 prepared with sepiolite and SiO2·nH2O showed total color difference ΔE value of 1.43 and 2.05, respectively, which was lower than that of unmodified PR 57:1 (ΔE = 2.89). In addition, the transmittance of pigment water suspension test results showed that the core-modified PR 57:1 showed better water dispersibility. Originality/value This paper attempts to develop a synergistic strategy based on the multipurpose use of inorganic materials in adsorption treatment of pigment wastewater and preparation of core-modified PR 57:1.
