Effects of different dietary lipid levels on physiological metabolism and odor quality of hepatopancreas in adult female Chinese mitten crab (Eriocheir sinensis)

Abstract Objectives This study aimed to investigate the impact of different dietary lipid levels on the physiological metabolism and odor quality of adult female Eriocheir sinensis during the fattening phase. Materials and Methods Five dietary schemes, each containing different total lipid levels (4%, 7%, 10%, 13%, and 16%), were administered over a 60-d fattening period for adult female crab (approximately 50 g, n=60). Chromatography and spectroscopy techniques were used for the detection of aroma and key aroma precursors. Results Dietary lipids had no significant effect on growth performance and hepatopancreas index (P<0.05). The carotenoid content showed an increasing and then decreasing trend, with a significant increase to 1312.51 mg/kg (P<0.05) at 7% lipid content of the diet. In contrast, a diet with a 13% lipid level led to a significant increase in total unsaturated fatty acids (115.3 mg/g, P<0.05), which maximized the contents of major fatty acids (oleic, linoleic, and linolenic, among others), and presented a fluctuating trend. A diet with higher lipid levels (16%) inhibited fatty acid accumulation. Moreover, a 13% dietary lipid level enhanced characteristic aroma compounds (for example, nonanal, octanal, hexanal, 3-methylbutanal, and 2-heptanone) in E. sinensis cooked hepatopancreas. Through an orthogonal partial least squares discriminant analysis model, it becomes evident that lipids and carotenoids together promote aroma formation in hepatopancreas. Conclusions Based on the current findings, the optimal dietary lipid level for enhancing the odor quality of hepatopancreas in adult female E. sinensis during the fattening phase was 13%. This study provides more precise options for the high-quality cultivation of E. sinensis.

Effects of Sodium Acetate Supplementation on Growth, Hematologic and Plasma Biochemical Parameter, Lipid Deposition, and Intestinal Health of Juvenile Golden Pompano Trachinotus ovatus Fed High-Lipid Diets.

Experimental diets were formulated including the suitable lipid level (10%, PC), the high-lipid level (16%, HL), and HL containing sodium acetate diets (HS). Three diets were fed golden pompano (Trachinotus ovatus) (initial body weight: 12.88 ± 0.03 g) for 8 weeks. The results showed HL diets significantly increased hepatosomatic index (HSI) and abdominal fat percentage (ASF), aggravated liver lipid deposition, and caused blood metabolic disorder and liver damage (P < 0.05). Moreover, the fish fed HL diets significantly decreased intestinal villus number (VN) and muscular layer thickness (MLT) (P < 0.05), accompanied with an increased trend in the relative abundance of intestinal pathogenic bacteria such as Mycoplasma and Photobacterium. However, the fish fed HS diets significantly decreased the HSI and AFP, relieved hepatic lipid deposition, improved blood and liver metabolism, and intestinal morphology in comparison to the fish fed HL diets (P < 0.05). More importantly, sodium acetate addition improved intestinal microbiota by inhibiting the proportion of pathogens (Mycoplasma and Vibrio) and increasing the abundance of probiotics (Bacteroidales_S24-7_group_norank, Cetobacterium, Bacteroides, and Lachnospiraceae_NK4A136_group). Furthermore, there was a strong correlation between these bacteria (Mycoplasma, Vibrio, Lachnospiraceae_NK4A136_group, Bacteroidales_S24-7_group_norank, Bacteroides, and Cetobacterium) and main physiological indices. In conclusion, sodium acetate improved blood performance, alleviated hepatic lipid deposition induced by HL diets, and boosted the growth and intestinal health for golden pompano.

ХАРАКТЕРИСТИКА ЛИПИДНОГО СПЕКТРА У БОЛЬНЫХ СТАБИЛЬНОЙ ИБС С ПОГРАНИЧНЫМ СТЕНОЗОМ КОРОНАРНЫХ АРТЕРИЙ

Introduction. Тherosclerosis is the main cause of cardiovascular diseases, including coronary heart disease (CHD). The presence of borderline coronary artery stenosis (CA) is determined in about 35-45% of cases. Aim. To evaluate the lipid spectrum parameters in patients with stable ischemic heart disease (CHD) with borderline stenosis of the coronary arteries (CA) with different clinical phenotypes. Material and methods. The study involved 201 patients with stable ischemic heart disease, functional class 1-3 angina with borderline (50-70%) coronary artery stenosis. Three groups of patients were identified based on clinical phenotypes: a group with the phenotype of stable ischemic heart disease with borderline coronary artery stenosis without diabetes mellitus (DM) and metabolic adverse obesity phenotype (MAOP), a group with the phenotype of stable ischemic heart disease with borderline coronary artery stenosis with DM, and a group with the phenotype of stable ischemic heart disease with borderline coronary artery stenosis and MAOP. Lipid spectrum parameters (TC, LDL, HDL, TG), APO B, APO A1, and the APO B/APO A1 ratio were assessed in all patients. Coronary angiography was performed. Results. The group of patients with the phenotype of stable ischemic heart disease with borderline stenosis of coronary arteries without DM and MAOP included 71 people, with the phenotype of stable ischemic heart disease with borderline stenosis of coronary arteries with DM – 51 patients, and with the phenotype of stable coronary artery disease with borderline stenosis of coronary arteries and MAOP – 79 patients. The groups of patients with different phenotypes did not differ in age, frequency of hypertension and age of its development, age of onset and duration of ischemic heart disease, as well as the frequency of previous MI. When assessing the lipid spectrum in patients with the phenotype of stable ischemic heart disease and diabetes mellitus, LDL and APO B levels were noted to be significantly lower with more frequent use of statins, and the TG level was significantly higher. In patients with stable ischemic heart disease phenotypes with borderline stenosis of coronary arteries without diabetes and MAOP, the level of protective APO A1 was significantly higher, and the frequency of an increase in the APO B/APO A1 ratio was significantly lower than in patients with other phenotypes. Conclusion. The most favorable lipid indices were determined in the group of patients with the stable IHD phenotype without diabetes mellitus and MAOP, although the patients had a similar duration of IHD and the frequency of MI in the anamnesis to those of patients with diabetes mellitus and MAOP. Patients with the stable IHD and diabetes mellitus phenotype compensated for high levels of proatherogenic lipids by taking statins, but they retained high TG levels, and patients with the stable IHD and MAOP phenotype were characterized by a more frequent decrease in APO A1. The frequency of an increase in the APO B/APO A1 ratio, as a proatherogenic index, was the highest in the IHD with diabetes mellitus and MAOP phenotypes.

Reduced toxic effects of nano‑copper sulfate in comparison of bulk CuSO4 on biochemical parameters in the Rohu (Labeo rohita)

Considering the wide application of nanoparticles in various fields of life and growing concern regarding their toxic effects, the present study was designed with the aim to evaluate the potential risks of using copper sulfate nanoparticles (CuSO4-NPs) in comparison to bulk form. Nanoparticles of CuSO4, having mean size of 73 nm were prepared by ball milling method, and fingerlings of Labeo rohita were exposed to two levels, 20 and 100 μg L−1 of CuSO4 in both bulk and nano forms for 28 days and their comparative effects on the metallothioneins (MTs), heat shock proteins 70 (HSP 70), lipid profile, cholesterol (CHOL) and triglyceraldehyde (TG) levels, activities of some metabolic enzymes Alanine transaminase (ALT), Aspartate transaminase (AST) Akaline phosphatase (ALP), and genes expressions of HSP-70, TNF-α and IL1-ß were investigated. CuSO4 showed the concentration and particle type dependent effects. The over expression of HSPs and MTs, significant decreases in CHOL, TG, low density lipid (LDL) levels and ALP activity, while significant increases in high density lipid (HDL)level as well as ALT and AST activities and HSP-70, TNF-α and IL1-β expressions were observed in response to higher concentration of both bulk and nano form of copper sulfate. At lower concentration (20 μg L−1), however, only bulk form showed toxicity. Thus, low concentrations of CuSO4-NPs pose negligible threat to freshwater fish.

Effect of systemic atorvastatin on bone regeneration in critical-sized defects in hyperlipidemia: an experimental study

PurposeHypocholesterolemic medications similar to atorvastatin are efficient in lowering blood lipid levels; however, compared to other medications in the statin family, their impact on bone metabolism is claimed to be insufficient. The impact of atorvastatin on bone regeneration in dental implantology in individuals with hyperlipidemia who received atorvastatin in the clinic is doubtful.MethodsIn the study, 16 male New Zealand rabbits of 6 months were used. All rabbits were fed a high-cholesterol diet for 8 weeks, and hyperlipidemia was created. It was confirmed that the total cholesterol level in rabbits was above 105 mg/dl. A critical-sized defect was created in the mandible. The defect was closed with xenograft and membrane. Oral 10 mg/kg atorvastatin was started in the experimental group, and no drug was administered in the control group. At 16th week, animals were sacrificed. For histomorphological examination, the new bone area, osteoclast, and osteoblast activities were evaluated.ResultsWhile new bone area (45,924 µm2, p < 0.001) and AP intensities (105.645 ± 16.727, p = 0.006) were higher in the atorvastatin group than in the control group, TRAP intensities in the control group (82.192 ± 5.346, p = 0.021) were higher than that in the atorvastatin group.ConclusionsIt has been found that high blood lipid levels will adversely affect bone graft healing and the use of systemic atorvastatin contributes to bone healing. Clinicians should pay attention to the selection of surgical materials, considering the importance of questioning drug use in their patients and the risks in cases of non-use.

Aims: To assess the biochemical, phytochemical and amino acid content from Cucumeropsis mannii dried seeds flours grown in Côte d'Ivoire (West Africa). &#x0D; Study Design: Experimental.&#x0D; Place and duration of study: Sample: Laboratory of Nutrition and Food Security, Nangui Abrogoua University&#x0D; Methodology: Cucumeropsis mannii seeds were obtained for this study from an experimental field in Gagnoa (Côte d’Ivoire). In March 2022, seeds were planted and after 7 months, the mature fruits that lead to the complete drying of the plant were harvested.&#x0D; Results: The biochemical composition of the seeds revealed that they contain varying proportions of carbohydrates, fibers, ash, total sugars with contents of 9.28 ± 0.79 %; 2.72 ± 0.30 %; 3.12 ± 0.38; 2.34 ± 0.05, respectively. High levels of lipids, proteins, dry matter and energy were observed in seed flour with values of 47.46 ± 1.55 %; 31.80 ± 1.16 %; 94.38 ± 0.6 %; 591.46 ± 1.17 kcal /100 g DM. The resulting flour reached a pH of 6.5. The study of phytochemicals showed varying levels of oxalate (0.32 g/100g DM), tannins (3.02 g TAE/ 100g DM), total polyphenols (8.12 mg GAE / g DM), total flavonoids (27.5 mg QE/g DM) and carotenoids (2.9 µg/100g DM). Furthermore, they were potential sources of essential amino acids, including histidine (905.6 mg/100g), isoleucine (844.5 mg/100g), threonine (730.1mg/100g), phenylalanine (550.0 mg/100g), valine (469.9 mg/100g), leucine (456.6 mg/100g), and methionine (358.5 mg/100g).&#x0D; Conclusion: The overall result implies that Cucumeropsis mannii seeds could be added to the food preparations of malnourished children.

Maternal metabolic profiling across body mass index groups: An exploratory longitudinal study.

Increased BMI has been identified as a risk factor for most pregnancy complications, but the underlying metabolic factors mediating the detrimental effects of BMI are largely unknown. We aimed to compare metabolic profiles in overweight/obese women (body mass index [BMI] ≥ 25 kg/m2 ) and normal weight/underweight women (BMI < 25 kg/m2 ) across gestation. We also explored how gestational weight gain (GWG) affected maternal metabolic profiles. Exploratory nested case-control study based on a prospective longitudinal cohort of women who were healthy prior to pregnancy and gave birth at Oslo University Hospital from 2002 to 2008. The sample consisted of 48 women who were overweight/obese and 59 normal-weight/underweight women. Plasma samples from four time points in pregnancy (weeks 14-16, 22-24, 30-32 and 36-38) were analyzed by nuclear magnetic resonance spectroscopy and 91 metabolites were measured. Linear regression models were fitted for each of the metabolites at each time point. Overweight or obese women had higher levels of lipids in very-low-density lipoprotein (VLDL), total triglycerides, triglycerides in VLDL, total fatty acids, monounsaturated fatty acids, saturated fatty acids, leucine, valine, and total branched-chain amino acids in pregnancy weeks 14-16 compared to underweight and normal-weight women. Docosahexaenoic acid and degree of unsaturation were significantly lower in overweight/obese women in pregnancy weeks 36-38. In addition, overweight or obese women had higher particle concentration of XXL-VLDL and glycoprotein acetyls (GlycA) at weeks 14-16 and 30-32. GWG did not seem to affect the metabolic profile, regardless of BMI group when BMI was treated as a dichotomous variable, ≥25 kg/m2 (yes/no). Overweight or obese women had smaller pregnancy-related metabolic alterations than normal-weight/underweight women. There was a trend toward higher triglyceride and VLDL particle concentration in overweight/obese women. As this was a hypothesis-generating study, the similarities with late-onset pre-eclampsia warrant further investigation. The unfavorable development of fatty acid composition in overweight/obese women, with possible implication for the offspring, should also be studied further in the future.

Huatanmaitong tablet alleviate cerebral ischemic reperfusion injury with hyperlipidaemia in rats by regulating OATPs/VEGF axis.

Stroke is the top priority pathogenesis of disability and death globally, affecting people worldwide. The presence of high levels of lipids in the blood has been confirmed as a vital factor of ischemic stroke. We aim to examine the effectiveness of Huatanmaitong tablet in hyperlipidemia rats that have experienced an ischemic stroke. We created a rat model of middle cerebral artery occlusion (MCAO) with hyperlipidemia as a basis. Following 8 weeks of high-fat diet, the model rats underwent MCAO surgery. Subsequently, the rats were administered huatanmaitong tablets and lipitor tablets as treatments. Therefore there are five groups, CONTROL, MCAO, hyperlipidemia (HLP), Huatanmaitong tablet (HTMTT) and Lipitor (LIPITOR) groups respective ly. To assess the efficacy of the medication, the serum lipid levels of rats were measured both prior to and following administration. Hematoxylin eosin staining was used to observe the alterations in the brain and liver structures within each group. VEGF and OATPs related factors were detected in brain, liver by using immunohistochemistry, Western blotting, and Quantitative PCR. After the model was established successfully, the infarct volume and behavioral scores of the model group, hyperlipidemia group, Huatan Maitong tablet group and Lipitor group had statistical differences (P<0.05). Blood lipid levels of rats were measured before and after treatment, and it was found that Huatanmaitong tablets effectively reduced these levels. Hematoxylin and eosin staining of the brain and liver showed that huatanmaitong tablets maintained the microstructure stability. Western blotting and real-time PCR revealed that Huatanmaitong tablets improved the expression level of organic anion transport (OATP1B1, OATP2B1) in rat tissues with ischemic stroke, enhancing the transmembrane transport of exogenous substances and maintaining homeostatic balance. Additionally, it down-regulated the expression of VEGF in various organs such as the brain, and liver, demonstrating the ability of Huatanmaitong tablets to remove phlegm, blood stasis, and promote circulation by regulating serum lipid levels, organic anion transport peptide, and VEGF in rats. The behavioral score of ischemic stroke rats can be improved and the neurological impairment symptoms of rats can be alleviated by Huatanmaitong tablet through the regulation of OATPS/VEGF axis.

Response surface methodology optimisation enhancing lactic acid production from Prosopis africana pods by Rhizopus oryzae

Microbial fermentation of lignocellulosic biomass into lactic acid (LA) has received considerable attention because it ensures the valorisation of wastes and reduces dependence on fossil sources. First, the proximate and phytochemical compositions of Prosopis africana pods (PAP) were determined. Previous biologically-pretreated pods of Prosopis africana were then saccharified using dilute acid hydrolysis following a full factorial design. The factors optimized were acid type (HCl and H2SO4), acid concentration (1 %, 3 % and 5 %), solid loading ratio (5 %, 10 % and 20 %) and reaction time (15, 30 and 60 minutes). Several Rhizopus oryzae isolates were screened for LA production and the most prolific was molecularly identified. The factors affecting LA yield from PAP hydrolysate were screened using a half-factorial design. The significant factors were then optimised using Box-Behnken Design of Response Surface Methodology (RSM). The proximate analysis showed high levels of protein, lipid, ash and carbohydrates. The phytochemical analysis of PAP revealed the presence of flavonoids, alkaloids, saponins, phenols, tannins, glycosides and terpenoids. The hydrolysis conditions of 3 % HCl, 20 % solid loading and 15 minutes hydrolysis time yielded the highest reducing sugars of 42.5 g/L. The most promising isolate, identified as R. oryzae strain AK-22, produced 19.7 g/L after RSM optimization, a 38.1 % increase over yields from non-optimised conditions. These findings are on the biotechnological production of LA from the pods of Prosopis africana, an abundant yet under-utilised tree crop.

Oleic acid as modulator of oxidative stress in European sea bass (Dicentrarchus labrax) juveniles fed high dietary lipid levels

Although the benefits of oleic acid (OA) have been established in mammals, its effects on fish remain understudied. The aim of this study was to evaluate the antioxidant potential of OA in the liver, intestine, and muscle of European sea bass juveniles fed diets containing different lipid levels. For that purpose, six diets with 16 or 22% lipids and 0, 1, and 2% OA were formulated and triplicate groups of European sea bass juveniles (21.4 g) were fed with these experimental diets for 9 weeks. Increasing dietary lipid levels or OA supplementation did not affect antioxidant enzyme activity in the liver and muscle. Superoxide dismutase (SOD) activity in the intestine increased with both the dietary lipid and OA levels, while glucose 6 phosphate dehydrogenase (G6PDH) activity increased only with dietary OA supplementation. Reduced glutathione (GSH) and total glutathione (tGSH) content were higher in the liver and intestine of fish fed the low-lipid diets, while in the high-lipid diets it was lower in the muscle than in the liver and intestine. Present findings suggest that OA plays a role in the antioxidant defense mechanisms of European sea bass, particularly at the intestine level, but additional research is required to further assess the potential benefits of incorporating OA into the diets.

Determination in the efficiency of the use of essential oils of oregano and hop as antioxidants in deep frying processes

AbstractThe aim is to evaluate the antioxidant efficiency of oregano essential oils (OEOs) and hops essential oils (HEOs) in a deep frying process of high‐oleic peanuts in high‐oleic peanut oil. There is no information available regarding the antioxidant behavior in deep frying. A combined vegetable oil/food system with high levels of lipids is susceptible to oxidation. High‐oleic peanut oil and high‐oleic peanuts are susceptible to oxidation involved in frying. The antioxidant effect of HEO and OEO was proved in frying peanut process (170°C) in peanut oil enriched at 0.02% p/p and compared with butylated hydroxytoluene (BHT) (0.02%) and control (without additives) during 8 h. Chemical oxidation indicators and volatile compounds were measured. 2,5‐Dimethylpyrazine (2,5‐DMP) and descriptive sensory analysis were measured in fried peanuts. High‐oleic peanut and oil are very stable in a frying process. OEOs and HEOs protected against the deterioration of the high‐oleic peanut oil: Peroxide value was 3.7, 2.8, 3.1, and 1.3 meq O2 kg−1 for control, BHT, HOP, and OEO, respectively. The addition of essential oils (EO) maintained the 2,5‐DMP in the fried peanuts. The use of EO of oregano and hop improves the stability of high‐oleic frying oil.Practical Applications: Deep frying processes generate the deterioration of the vegetable oils used for cooking food. This deterioration reduces the shelf life of the frying oil and the quality of the food, even generating compounds that are toxic to the health of consumers. Antioxidants are used as measures that can help to reduce spoilage, but synthetics are being questioned. Natural products offer an alternative and essential oils, due to their high hydrophobic interaction with the oils, generate a strong interaction, remaining in the frying oil for its protection even at high‐temperature thermal processes. This alternative is a possibility because of the protection it generates in the deep frying process.

Nrf2 inhibition regulates intracellular lipid accumulation in mouse insulinoma cells and improves insulin secretory function

High amount of fat in the pancreas is linked to poor functioning of β-cells and raises the risk of type 2 diabetes. Here we report the putative role of a circulatory glycoprotein Fetuin-A, a known obesity marker, in promoting lipid accumulation in β-cells and its association with Fatty acid translocase/CD36 for lipid storage culminate in β-cell dysfunction. Additionally, this work reveals regulation of CD36 via Nrf2, a key regulator of oxidative stress, and reduction of lipid accumulation by suppression of Nrf2 that restores β-cell function. Palmitate (0.50 mM) and Fetuin-A (100 μg/mL) exposure showed high levels of intracellular lipid in MIN6 (mouse insulinoma cells) with a concomitant decrease in insulin secretion. This also increased the expression of important lipogenic factors, like CD36, PGC1α, PPARγ, and SREBP1. Flow cytometry analysis of CD36 membrane localization has been corroborated with an increased accumulation of lipids as indicated by Oil-Red-O staining. Immunoblotting and immunofluorescence of Nrf2 indicated its high expression in palmitate-fetuin-A incubation and translocation in the nucleus. Suppression of Nrf2 by siRNA showed a reduced expression of lipogenic genes, ablation of lipid droplets, decrease in the number of apoptotic cells, and restoration of insulin secretion with a corresponding increase of Pdx1, BETA2, and Ins1 gene expression. Our study thus suggested an important aspect of lipid accumulation in the pancreatic β-cells contributing to β-cell dysfunction and demonstrated the role of Fetuin-A in CD36 expression, with a possible way of restoring β-cell function by targeting Nrf2.

Higher matrix stiffness promotes VSMC senescence by affecting mitochondria-ER contact sites and mitochondria/ER dysfunction.

Abdominal aortic aneurysm (AAA) is a prevalent condition characterized by the weakening and bulging of the abdominal aorta. This study aimed to investigate the impact of a stiff matrix on vascular smooth muscle cells (VSMCs) in AAA development. Bioinformatics analysis revealed that differentially expressed genes (DEGs) in VSMCs of an AAA mouse model were enriched in cellular senescence and related pathways. To simulate aging-related changes, VSMCs were cultured on stiff matrices, and compared to those on soft matrices, the VSMCs cultured on stiff matrices exhibited cellular senescence. Furthermore, the mutual distance between mitochondria and endoplasmic reticulum (ER) in VSMCs was increased, indicating altered mitochondria-endoplasmic reticulum contacts (MERCs). The observed upregulation of reactive oxygen species (ROS) levels, antioxidant gene expression, and decreased mitochondrial membrane potential suggested the presence of mitochondrial dysfunction in VSMCs cultured on a stiff matrix. Additionally, the induction of ER stress-related genes indicated ER dysfunction. These findings collectively indicated impaired functionality of both mitochondria and ER in VSMCs cultured on a stiff matrix. Moreover, our data revealed that high lipid levels exacerbated the effects of high matrix stiffness on VSMCs senescence, MERC sites, and mitochondria/ER dysfunction. Importantly, treatment with the antilipemic agent CI-981 effectively reversed these detrimental effects. These findings provide insights into the role of matrix stiffness, mitochondrial dysfunction, ER stress, and lipid metabolism in AAA development, suggesting potential therapeutic targets for intervention.

Dyslipidemias: Prevalence and Associated Factors among Lactating Women in a Lower- and Middle-Income Country, Ghana.

Dyslipidemia, an abnormally high level of lipids in the blood, has a negative impact on the health status of the individual and has lately emerged as a major public health concern, especially for low- and middle-income countries (LMIC) globally, including Ghana. However, it is still unclear what the burden and drivers of these lipid abnormalities are, especially among lactating women in the Upper West of Ghana. Thus, this study is aimed at determining the prevalence of dyslipidemia and its associated factors among lactating mothers in the Wa Municipality of Ghana. Methodology. A cross-sectional study was conducted from May to June 2020 in 8 health facilities within the Wa Municipality. Multistage and simple random sampling methods were used to select the facilities and the 200 study subjects. Sociodemographic data were collected using questionnaires, while blood samples were taken to determine the lipid profile of participants. Dietary patterns were also assessed using the Food Frequency Questionnaire (FFQ). Data were processed and analyzed using SPSS 17 software (SPSS, Inc., Chicago, IL). The chi-square test and multiple regression analysis were performed to determine the predictors associated with the various types of dyslipidemia, with statistical significance set at a p value < 0.05. The prevalence of hypercholesterolemia (LDL-C), hypo-HDL-cholesterolemia, and hypertriglyceridemia (TG) was 57%, 59%, and 22%, respectively. Chi-square and multinomial regression analysis revealed that duration of lactation (X2 = 3.95, p = 0.047), religion (AOR = 0.375, 95% CI 0.144-0.978, p = 0.045), low income (AOR = 0.116, 95% CI 0.026-0.514, p = 0.005), middle income (AOR = 0.163, 95% CI 0.044-0.600, p = 0.006), and alcohol intake (AOR = 6.312, 95% CI 1.108-35.949, p = 0.038) were associated with LDL-C, while age (AOR = 0.963, 95% CI 0.910-1.019, p < 0.001) and educational status (AOR = 0.365, 95% CI 0.140-0.954, p = 0.040) predicted HDL status. Dyslipidemia is common among lactating mothers of Wa Municipality, and it is predicted by lifestyle factors. Furthermore, future research to look at a larger sample size on dyslipidemia during lactation is recommended.

Comparitive Nutritional Analysis Of Sweet Yam Bean (Jicama) Milk With Soya Milk -- A Review

The current research focuses on conducting a comprehensive nutritional comparison between sweet yam bean milk and soy milk. Sweet yam bean, also known as Jicama, is an ancient Mexican root vegetable akin to potatoes or turnips. It is safe for consumption, possesses a slightly sweet taste, and has low sugar content, making it a suitable carbohydrate source for individuals with diabetes or those pursuing a low-sugar diet. On the other hand, soy has been a staple ingredient for thousands of years. The study involved an examination of the proximate composition, mineral content, protein fractions, antinutritional elements, and rotenoids in the seeds of Pachyrhizus erosus, the sweet yam bean. In comparison to other legumes, soy seeds exhibited high levels of proteins, lipids, iron (Fe), and calcium (Ca). The predominant protein fraction was mainly composed of globulins, followed by glutelins. Minimal amounts of antinutritional compounds, such as tannins, hemagglutinating activity, and trypsin inhibitory activity, were detected in the sweet yam bean seeds. By conducting this comprehensive comparative analysis, we aim to provide valuable insights into the nutritional benefits and potential applications of sweet yam bean (Jicama) milk, especially in relation to soy milk, which has been a longstanding nutritional staple.

Ontogeny of the digestive enzyme activity of the pikeperch (Sander lucioperca) under culture condition

The pikeperch (Sander lucioperca) is a species with a high potential for aquaculture and a valuable food with high market acceptance. The aim of the study was to evaluate the functional ontogeny of digestive enzyme of pikeperch from hatching to 45 days-post fertilization, 777 degree-day (DPF, dd) under culture condition. The average total length (TL) of larvae measured at hatching was 3.6 ± 0.4 mm (5 DPF; 67 dd) and at the end of experiment (45 DPF, 777 dd) was 27.1 ± 1.1 mm. The survival rate was 80–90% during the experiment period. Inhibition zimography reveals the presence of nine bands with proteolytic activity in the digestive tract of juvenile pikeperch. Zimography results during the ontogeny revealed that in larvae at 8 DPF (108 dd) and 13 DPF (189 dd), three bands were presented. The variations observed in the enzymatic activity reflected a high amount of total protease activity at 10 DPF (133.5 dd). Regarding pepsin, its activity was observed for the first time at 26 DPF (378.9 dd). Lipase activity remained constant from hatching to 26 DPF (378.9 dd). The highest amount of α-amylase activity was detected at 15 DPF (211.5 dd) and 45 DPF (777 dd). The low lipase enzyme activity suggested that live feeds with low lipid were more suitable than diets containing high lipid levels; larvae had also early capability to digest nutrient-dense diet that was high in protein. According to results the pikeperch larvae possess after the exogenous feeding, a functional digestive system with high activities that indicated the gradual development of the digestive system.

Decaffeinated coffee and green tea extract inhibit foam cell atherosclerosis by lowering inflammation and improving cholesterol influx/efflux balance through upregulation of PPARγ and miR-155

Background Foam cells are markers of atherosclerosis and characterise advanced atherosclerotic plaque, stimulated by inflammation caused by high lipid levels in macrophages. The combination of decaffeinated coffee and green tea extract (DCGTE) has been suggested to have a role in foam cell inhibition. Objective We investigated the inhibiting role of DCGTE against foam cell formation, through modulation of the inflammation process and cholesterol metabolism in macrophage colony stimulating factor- (M-CSF) and oxidized low-density lipoprotein (oxLDL)-exposed macrophages. Methods Coffee and green tea were extracted by filtration and infusion respectively, and underwent decaffeination using active carbon and blanching methods, respectively. Cells were administered 160/160 and 320/320μg/ml of DCGTE. Foam cell formation was observed using a light microscope after staining with Oil Red O (ORO), and the accumulation of lipids in macrophages with ELISA. Observations of lipid influx and efflux were determined through semiquantitative cluster differentiation 36 (CD36) and ATP binding cassette transporter A1 (ABCA1) expression through immunofluorescence. The inflammation process was quantified using inflammatory/anti-inflammatory markers, e.g., tumor necrosis factor α (TNFα) and interleukin 10 (IL10) with ELISA. Peroxisome proliferator activated response γ (PPARγ) expression and activity were assessed with PCR and ELISA, respectively. The expression of microRNA 155 (miR-155) was examined using qPCR. Results DCGTE at the above concentrations tended to reduce foam cell numbers, significantly inhibited lipid accumulation (p=0.000), reduced CD36 expression (p=0.000) and TNFα secretion (p=0.000) in Raw264.7 exposed to M-CSF 50ng/ml and oxLDL 50μg/ml. PPARγ expression (p=0.00) and activity (p=0.001), miR-155 relative expression (p=0.000), and IL10 production (p=0.000) also increased. Conclusion DCGTE lowered foam cell numbers, possibly through attenuation of the inflammatory process and improvement of lipid/efflux mechanisms in M-CSF and oxLDL-stimulated Raw264.7 cells, via upregulation of PPARγ and miR-155. Our results suggest DCGTE may help prevent atherosclerosis-based diseases.

The Cycle study: a prospective study on cholesterol levels during the menstrual cycle

Abstract Background Previous studies showed fluctuating lipid levels during the menstrual cycle in healthy women with normal cholesterol (nChol). Cycle-related variations in lipid levels in women with familial hypercholesterolemia (FH) have not been studied, while these might have important consequences for lipid management. Purpose To investigate menstrual cycle-related fluctuations in lipid levels in women with FH compared to those with nChol. Methods In the Netherlands and Norway, 20 women with clinical/genetic FH and 63 healthy women with nChol were included - details are presented in the figures. Participants had to have a regular cycle between 21-35 days, while pregnant women, and those using hormone-based contraceptives without hormone free interval (HFI) were excluded. Lipid levels were measured in the follicular (visit 1), ovulation (visit 2), and luteal (visit 3) phases. In women using oral contraceptives (OC) measurements were taken during day 12-14 of the pill period (visit 1) and during day 5-7 of the HFI (visit 2). Results Mean (sd) age of the included subjects was 33 (9) years, BMI 23.9 (4) kg/m2, and cycle duration 28 (2) days. These characteristics were similar in FH and nChol. Women with nChol showed slight, although statistically significant, cycle-related variations in cholesterol levels (mean maximum variation total Chol 0.53, LDL-Chol 0.39 and HDL-Chol 0.22 mmol/L; figure 1). FH women who did not receive statin therapy for various reasons showed largest mean variations (total Chol 0.80, LDL-Chol 0.59 and HDL-Chol 0.23 mmol/L), with the highest lipid levels during the ovulation phase. The women with OC had an increase in total- and LDL-cholesterol (groups combined: mean difference 0.55 and 0.51 mmol/L, respectively) between the two visits (n=9) (figure 2). Conclusions In women with untreated FH and normal cholesterol with a regular menstrual cycle, total- and HDL-cholesterol were highest at ovulation. These menstrual fluctuations were absent in women with FH who used statins. Women with OC showed an increase in total- and LDL-cholesterol from the contraceptive pill period to the HFI. Even though in most women the absolute variation in lipid levels during the menstrual cycle and OC are modest, the moment of measurement can be of clinical value in particular in women with untreated high lipid levels. In these women, it is recommended to measure lipid levels at a fixed time of the menstrual cycle.Figure 1Figure 2

Melon seed: A nutritionally valuable by-product and its effects on cake quality.

Incorporating by-products and waste materials with nutritional and industrial potential into food formulations is an important consideration. Melon seeds, known for their nutritious compounds, are often treated as waste. This study aimed to improve the nutritional properties of cakes by adding melon seed flour (MSF), which contains high levels of ash, lipid, protein, and fiber, as a substitute for whole wheat flour and fat at concentrations of 40% and 60%. The primary fatty acid identified was linoleic acid, while the dominant amino acid in the samples was glutamic acid, followed by proline and leucine. It is noteworthy that potassium and magnesium content in MSF was about five times higher than control. The substitution of MSF did not cause a significant change in the structural properties of the cakes but led to a decrease in the firmness, springiness, and chewiness. Consumer acceptance, based on sensory evaluation, indicated that cakes with 40% MSF substitution were well-received. In conclusion, our findings demonstrate that melon seeds, previously considered waste, can serve as a good alternative source of fiber, fat, and protein in bakery products.
