Lower Serum Cholesterol Levels Research Articles

The Relationship Between Serum Cholesterol, Triglycerides, and Self-Reported Appetitive and Reactive Aggression, as Well as Violent Crimes in Male Forensic Patients with Substance Use Disorder

Numerous studies have linked lower levels of serum cholesterol with heightened aggression, violent crimes, and violent deaths across diverse populations, including forensic psychiatric patients, criminals, and the broad public. Interestingly, this association appears to be more pronounced in men than in women. Conversely, findings regarding serum triglycerides present a more nuanced picture, with some studies indicating heightened aggression with elevated levels and others suggesting the opposite. However, most studies have neglected to examine this phenomenon in conjunction with psychological traits. Additionally, no prior research has explored the association between serum lipid levels and different types of aggression, e.g., reactive, instrumental, or appetitive. Considering these gaps, our study aimed to assess serum cholesterol and triglyceride levels upon clinic admission and correlate them with scores from the Appetitive and Facilitative Aggression Scale (AFAS), a self-rating questionnaire assessing reactive and appetitive aggression. We conducted our investigation on a cohort of 135 forensic psychiatric patients undergoing drug addiction treatment under Section 64 of the German Criminal Code. This provision offers a nearly unique opportunity worldwide for individuals who have committed crimes under the influence of drugs or in the context of their addiction to receive specialized treatment. Using non-linear Spearman correlation analyses, we observed an inverse relationship between serum concentrations of both cholesterol and triglycerides and AFAS appetitive violence scores but not for reactive aggression. Additionally, triglyceride levels exhibited an inverse association with the prevalence of violent crimes as an index crime. In conclusion, blood lipids may affect numerous areas of health and disease beyond what is currently known, offering a potential shift in how we understand their role in aggression.

Leukemia Inhibitory Factor Receptor inhibition by EC359 reduces atherosclerotic stenosis grade in Ldlr-/- mice

Cytokines are involved in all stages of atherosclerosis, generally contributing to disease progression. Previously, members of the IL-6 cytokine family, such as Interleukin-6, oncostatin M, and cardiotrophin-1, have been extensively studied in atherosclerosis. However, the role of leukemia inhibitory factor (LIF), member of the IL-6 family, and its receptor (LIFR), remains to be further elucidated. Therefore, the aim of this study is to provide insight in LIF receptor signalling in atherosclerosis development.Single-cell RNA sequencing analysis of human carotid artery plaques revealed that mast cells highly express LIF, whereas LIFR was specifically expressed on activated endothelial cells. A similar expression pattern of Lifr was observed in mouse atherosclerotic plaques. Next, female Western-type diet fed Ldlr-/- mice were treated with LIF receptor inhibitor EC359 (5 mg/kg s.c., n=15) or control solvent (n=15) three times per week for eight weeks. Stenosis grade was reduced in the aortic root of EC359 treated mice compared to control mice, but treatment did not affect plaque composition. Serum cholesterol levels were significantly reduced in EC359 treated mice, likely attributed to a reduction in VLDL cholesterol levels. Furthermore, LIF receptor inhibition reduced Pecam1 and Vcam1 expression in the aorta. Consequently, immune cell infiltration was reduced in aortic plaques of EC359 treated mice compared to control mice.Conclusively, we demonstrated that LIF receptor is a potential therapeutic target in atherosclerosis by reducing plaque size, attributed to lower serum cholesterol levels, reduced endothelial activation and less immune cell infiltration in the plaque.

Highland Barley Alleviates High-Fat Diet-Induced Obesity and Liver Injury Through the IRS2/PI3K/AKT Signaling Pathway in Rats.

Objectives: Highland barley (HB) consumption offers numerous health benefits; however, its impact on glycolipid metabolism abnormalities induced by a high-fat diet remains unclear. Consequently, this study aimed to investigate the therapeutic effects and underlying molecular mechanisms of HB in the context of obesity; Methods: Rats were fed either a high-fat diet (HFD) to induce obesity or a standard diet (SD) for six weeks. The rats in the HFD group were randomly assigned into five groups: HFD+HFD, HFD+SD, and low (30%), medium (45%), and high (60%) doses of the HB diet for an additional ten weeks. Analyses of serum lipid profiles, liver histology, transcriptomes, and untargeted metabolomes were conducted; Results: HB intake resulted in decreased weight gain, reduced feed intake, lower serum triglyceride and cholesterol levels, and diminished hepatic lipid accumulation. It also improved insulin and fasting blood glucose levels, and antioxidant capacity in the HFD-fed rats. Transcriptome analysis revealed that HB supplementation significantly suppressed the HFD-induced increase in the expression of Angptl8, Apof, CYP7A1, GDF15, Marveld1, and Nr0b2. Furthermore, HB supplementation reversed the HFD-induced decrease in Pex11a expression. Untargeted metabolome analysis indicated that HB primarily influenced the pentose phosphate pathway, the Warburg effect, and tryptophan metabolism. Additionally, integrated transcriptome and metabolome analyses demonstrated that the treatments affected the expression of genes associated with glycolipid metabolism, specifically ABCG8, CYP2C12, CYP2C24, CYP7A1, and IRS2. Western blotting confirmed that HB supplementation impacted the IRS2/PI3K/AKT signaling pathway; Conclusions: HB alleviates HFD-induced obesity and liver injury in an obese rat model possibly through the IRS2/PI3K/Akt signaling pathway.

Cardiovascular Health and Diet Quality among Vegetarians, Vegans and Omnivores: Insights from a Large Urban Population in Poland.

Background/Objectives: Dietary habits are among the most significant determinants of health. The aim of this study was to assess the nutritional quality and cardiovascular profiles of individuals following plant-based diet. Methods: The study population comprised 199 individuals (136 women, 63 men; mean age 33.9 ± 8.9 years) including vegans (VG; n = 50), vegetarians (VN; n = 101) and omnivores (OV; n = 48). In this analysis the following procedures were assessed: a questionnaire interview, anthropometric and blood pressure measurements, and a blood sample collection. Dietary patterns were evaluated using the Food Frequency Questionnaire and a 24-h dietary recall. Results: Vegans exhibited the lowest protein intake relative to the other groups (p < 0.05) and a significantly higher intake of polyunsaturated fatty acids and lower intake of cholesterol compared to VN and OV (p < 0.05). Vegans had significantly lower levels of serum cholesterol, LDL cholesterol, and triglycerides, fasting glucose and high-sensitivity C-reactive protein (p < 0.05). No cases of overweight or obesity were observed among VN and VG participants. No instances of impaired fasting glucose or elevated blood pressure were noted among vegans. Hypercholesterolemia was identified in 56.2% of OV, 26.7% in VN and 16.0% in VG (p < 0.05), elevated blood pressure was recorded in one vegetarian and in 6.2% of OV participants. Conclusions: Our research indicates that plant-based diets are associated with a better cardiovascular profile compared to traditional diets. Moreover, suboptimal intake of essential nutrients, underscores the need for more effective public health interventions and improved nutrition education regardless of dietary patterns.

Serum cholesterol in children with ASD

Objectives. Because the brain contains one-quarter of all cholesterol in the body, cholesterol has a significant effect on the brain. Cholesterol may also have an impact on autism, which is associated with poor brain development. Damage to neurons can lead to the emergence of autism spectrum disorders (ASD). This is a case-control study conducted to explore the potential association between serum cholesterol level and ASD in children’s patients. Material and methods. It involved collecting data from medical records, performing interviews, and taking blood samples from patients and a control group of children. The samples consisted of 60 child patients with ASD and an equal number of controls, for a total of 120 participants. Outcomes. There was a significant inverse relationship between cholesterol levels and ASD. The children diagnosed with ASD displayed significantly lower cholesterol levels when compared to healthy children (p-value = 0.004). The age distribution of the participants showed a non-significant difference between the ASD patient group and the control group (p-value = 0.085). This supports the existing knowledge that ASD is more common in children under the age of 18. Conclusions. Children with ASD had a lower total serum cholesterol level than healthy children. This may suggest that there is an inverse relationship between serum cholesterol levels and disease state in children diagnosed with ASD who have lower cholesterol levels. Also, significant differences of gender and BMI were found among study groups, suggesting their association with the disease’s development and consequences. The results of the study also highlight some significant differences in the main basic characteristics of ASD in patients, evaluating their possible roles with the disease’s roots and with serum cholesterol, on the other hand. These findings contribute to a deeper understanding of the sophisticated relationship between cholesterol level and ASD development, potentially opening up new ways for the update of intervention, treatment, and follow-up strategies.

Lower total cholesterol and triglyceride levels in ankylosing spondylitis than non-inflammatory rheumatic disease controls in a 1978-98 study: a potential effect of increased physical energetics in manual occupations in the pre-2000 chronologic era.

No article on serum lipids in ankylosing spondylitis (AS) and control subjects has been reported from USA. The primary aim of this study was to determine if any difference occurred in serum lipid levels in AS and control rheumatic disorders in two time periods, 1978-98 and 2000-10. The secondary aim was to investigate variables associated with lipid levels and if a difference was found between AS and control disorders. The AS patients were compared to non-inflammatory rheumatic disorders (NIRDs) in 1978-98 and 2000-10 surveys and to rheumatoid arthritis (RA) in the 2000-10 survey. Patients were matched within 5 years of age, sex, and clinic or hospital source. In the 1978-98 survey, entry mean (SEM) serum cholesterol level [mg/dL] was highly (p<0.001) significantly lower in 69 AS [179.0 (4.8)] than 69 matched NIRD controls [208.0 (5.6)]. In 29 pairs of AS and NIRD subjects having manual labour occupations, mean (SEM) cholesterol level was additionally lower in AS [156.7 (5.9)] and higher in 29 NIRD controls [213.3 (8.6)] (p<0.001). In manual labour workers, mean (SEM) serum triglyceride was significantly lower (p=0.004) in 15 AS [110.3 (14.1)] than 14 NIRD controls [185.2 (19.3)]. In the 2000-10 survey, no lipid difference was found between AS vs. NIRD control patients. In the 1978-98 survey, AS had significantly lower mean serum cholesterol and triglyceride levels than NIRD control patients. Associated manual labour occupations may have significantly contributed to results, possibly related to increased energy expenditures from physical activity in the pre-2000 era.

Effect of Local Simvastatin on the Healing of Surgically Created Critical-Sized Bone Defects: An experimental Study on sheep.

Background and objective: the role of simvastatin in lowering serum cholesterol levels is well described. However, recent findings suggest they have a role in bone formation as well. The study aims to determine the effect of local simvastatin application on bone defect healing and compare the amount of new bone produced by a simvastatin-treated defect with that produced by a bone graft (biphasic calcium phosphate) and non-treated defects (left empty) histologically. Methods: Forty-five critical-size defects were created (8mm in diameter and depth) in the iliac bone of 6 sheep. For the first three sheep (5 defects/ilium), the five defects on the right ilium were left empty as a Control group, while the five defects on the left ilium were filled with biphasic calcium phosphate as Test 1 group. For the other three sheep, 5 defects were created on the right ilium, the defects were filled with 10mg crushed simvastatin tablet with gelfoam (as a carrier) as Test 2 group. The animals were sacrificed over periods of 1, 2, and 3 months. Histopathological studies were done for all the samples. SPSS version 28 was used to analyze the results. The numerical variables were checked for normality using Smirnov – Kolmogorov test, then analyzed using ANOVA and unpaired t-test (p–values ≤ 0.05 were considered statistically significant). Results: All 6 adult male sheep passed the scheduled periods uneventfully. During the wound healing period, there was no complication such as infection, excessive hematoma, or wound dehiscence. All 45 standardized iliac bone defects were included in the final analysis (n= 45). The histologic results showed that Test 2 group (defect filled with simvastatin) in the 1st, 2nd, and 3rd months had significantly higher bone formation at the surface and depth of the defects than Test 1 and Control group with P values (&lt;0.0001) at all period intervals. Conclusion: Simvastatin enhances bone formation and accelerates the healing process of the bony defect. Keywords: Bone formation, Bone graft, Bone healing, Simvastatin, Statin.

Effects of Dietary Inclusion of Angelica gigas Nakai root extract on the Growth Performance, Hematological and Serum Biochemical Parameters in Broilers

The study aimed to evaluate the impact of dietary supplementation with Angelica gigas Nakai (AGN) root extract on growth performance, hematological indices, and serum biochemical parameters in broiler chickens. A total of 320 straight-run Cobb broiler chicks from a commercial hatchery were distributed among four treatment groups: Basal diet (BD) as the Control; Treatment 1 (T1): BD + 2 g/kg AGN; Treatment 2 (T2): BD + 4 g/kg AGN; and Treatment 3 (T3): BD + 8 g/kg AGN), each comprising eight replicates with 10 birds per replicate. The supplementation of AGN resulted in dose-dependent improvements (P &lt; 0.05) in body weight, gain, and feed efficiency. On both day 21 and day 35, increasing AGN dosage in the diet led to a significantly higher (P &lt; 0.05) values of red blood cells (RBCs), white blood cells (WBCs), hemoglobin (Hb), and packed cell volume (PCV). By day 21, AGN supplementation dose-dependently decreased (P &lt; 0.05) serum alkaline phosphatase (ALP), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), urea, and creatinine levels. Meanwhile, AGN dose escalation correlated with a notable increase (P &lt; 0.05) in serum total protein (TP), albumin, and globulin levels. On day 35, increasing AGN levels led to a significant reduction (P &lt; 0.05) in serum AST and ALT activity, along with lowered serum glucose, cholesterol, triglycerides, urea, and creatinine levels. In conclusion, AGN supplementation enhanced growth performance and positively influenced hematological indices and serum biochemistry profiles in broiler chickens. The study confirms the safe and effective utilization of AGN at an 8 g/kg (0.8 %) feed additive dosage to optimize broiler performance. These findings provide valuable insights into the potential benefits of AGN in poultry nutrition.

Low serum total cholesterol levels predict inferior prognosis of patients with POEMS syndrome

Low serum cholesterol levels are associated with increased tumor morbidity and mortality. However, the relationship between serum lipid profile and POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes) is still unclear. The aim of our study was to clarify the importance of the serum lipid profile in predicting the severity and prognosis of patients with POEMS syndrome. Forty-three patients with newly diagnosed POEMS syndrome admitted to the Department of Hematology of Jiangsu Provincial People's Hospital between August 2013 and February 2023 were selected. They had explicit serum lipid profiles. There were 27 males and 16 females with a median age of 54 years (range, 28–77 years). Survival curves were plotted using the Kaplan–Meier method, and comparisons between the two groups were performed using the log-rank test. The Cox proportional-hazards model examined risk factors associated with the prognosis of POEMS syndrome. Receiver-operator characteristic (ROC) curves assessed the predictive accuracy. 23 (53.5%) patients had low total cholesterol (TC) levels. Low levels of TC were concerned with unfavorable progression-free survival (PFS) (p = 0.007) and overall survival (OS) (p = 0.004), and at the same time, the low circulating TC concentration was an independent risk factor for PFS (p = 0.020) and OS (p = 0.011). Low TC values could improve the risk stratification, especially in high-risk patients. In conclusion, low serum TC levels may predict inferior prognosis in patients with POEMS syndrome; in future clinical application, low TC may be a reliable indicator of prognosis.

Medicinal herbs consumption in relation to cardiometabolic indices and coronary artery stenosis in participants undergoing coronary angiography: A cross-sectional study.

Few studies have investigated the association between herbal medicine consumption and coronary artery disease severity. This cross-sectional study aimed to investigate the association between the frequency of medicinal herbs consumption and coronary artery stenosis (CAS), lipid profile, fasting blood sugar (FBS), and blood pressure level in participants undergoing coronary angiography. This study was conducted on 662 participants aged 35-75 years. Serum cardiometabolic markers were measured using standard kits. The extent and severity of CAS were evaluated using the Gensini score (GS) and syntax score (SS). Higher consumption of Thymus vulgaris and Sumac was associated with decreased odds of artery-clogging according to the GS. A higher intake of Thymus vulgaris and Mentha was associated with lower levels of serum cholesterol and triglyceride. Monthly intake of Thymus vulgaris, and weekly/daily intake of Mentha, Nigella Sativa, and Cuminum Cyminum were associated with lower low-density lipoprotein. Weekly/daily intake of Turmeric and Thymus vulgaris were associated with lower high-density lipoprotein levels and monthly intake of Mentha was related to lower serum FBS levels. Higher consumption of Mentha, Mentha pulegium L, Lavandula angustifolia, and Nigella Sativa was associated with lower levels of systolic blood pressure. According to the results of the present study, herbs consumption might be related to a reduction in CAS risk factors.

A detection system for serum cholesterol based on the fluorescence color detection of beta-cyclodextrin-capped gold nanoclusters

Cholesterol is one of the major markers for cardiovascular diseases. Herein, a portable cholesterol measurement system based on fluorescence color detection was constructed by combining the high sensitivity of fluorescence analysis with the ease of color sensing to determine low levels of serum cholesterol. Cyclodextrin capping gold nanoclusters with blue-green emission were used as fluorescent probes because cholesterol exposure induced fluorescence enhancement of the probe due to the host–guest inclusion interaction between cholesterol and the cavity of cyclodextrin. The integrated sensing system consisted of modules including a microprocessor, a power supply, an LED light with a constant current source, an RGB color sensor, a display, and a darkroom. All the modules except the display screen were placed in a 3D printing darkroom to avoid interference from ambient light. An RGB color sensor TCS230 was applied to capture the RGB signals of the fluorescent color of the probe solution before and after cholesterol addition. Then the obtained RGB signals were converted into the signals in Hue, Saturation, and Value (HSV) color space with a central control chip STM32F407. The Hue value of the fluorescent color of the solution can discriminate the concentration change of cholesterol. Experimental results demonstrate that the system responds linearly to cholesterol in the concentration range of 20.00 ∼ 150.00 μmol·L-1 with a detection limit of 16.07 μmol·L-1 (3σ, n = 3). The detection of the system has good consistency and accuracy compared with the standard instrument, showing potential for the detection of low levels of serum cholesterol.

Influence of ultrasound on Pleurotus pulmonarius (Fr.) Quél. (Grey Oyster Mushroom) – Protective Effects Against Metabolic Syndrome in Rats Fed with a High-fat Diet

The Pleurotus pulmonarius (Fr.) Quel. (Grey Oyster mushroom) is one of the most widely consumed mushroom species worldwide, and it possesses various medicinal properties. The application of ultrasound resulted in P. pulmonarius extracts with improved bioactivities both in cellular and animal models. However, no studies have investigated the preventive effects of ultrasound extract of P. pulmonarius in animal models. In this study, Wistar-Kyoto rats were pre-treated with the ultrasound extract of P. pulmonarius at high (500 mg/kg bw) and low (200 mg/kg bw) doses for 15 days. The rats were subsequently fed with a high-fat diet (HFD) for another 15 days. Rats pre-treated with P. pulmonarius extract from a high-dose ultrasound showed lower levels of serum cholesterol (1.50 mmol/L), triglyceride (0.60 mmol/L), and LDL (0.29 mmol/L). These rats also had lower oxidative stress, with MDA levels of only 10.81 µg/mg protein. The ultrasound extract of P. pulmonarius also exhibited anti-hyperglycaemic effects, whereby rats had lower blood glucose levels. Rats pre-treated with the ultrasound extract of P. pulmonarius also had inhibited inflammatory biomarkers CREB1 (2.85 pmol/mL), NF-κB2 (0.81 ng/mL), and STAT3 (0.48 ng/mL), proving the anti-inflammatory activity of the ultrasound extract. This study is the first to show the ability of P. pulmonarius extract prepared using ultrasound to prevent developing metabolic syndrome such as hyperlipidaemia, hyperglycaemia, oxidative stress, and inflammation in rats fed with HFD.

Lower serum cholesterol levels as a risk factor for critical illness polyneuropathy: a matched case–control study

Critical illness polyneuropathy (CIP) is a frequent and underdiagnosed phenomenon among intensive care unit patients. The lipophilic nature of neuronal synapses may result in the association of low serum cholesterol levels with a higher rate of CIP development. We aimed to investigate this issue in critically ill patients. All cases diagnosed with CIP in our tertiary care hospital between 2013 and 2017 were 1:1 matched with controls without the condition by age, sex, and ICD diagnoses. The main risk factors examined were the differences in change between initial and minimum serum total cholesterol levels, and minimum serum total cholesterol levels between matched pairs. Other predictors were serum markers of acute inflammation. We included 67 cases and 67 controls (134 critically ill patients, 49% female, 46% medical). Serum total cholesterol levels decreased more profoundly in cases than controls (median: −74 (IQR −115 to −24) vs. −39 (IQR −82 to −4), median difference: −28, 95% CI [−51, −5]), mg/dl). Minimum serum total cholesterol levels were lower in the cases (median difference: −24, 95% CI [−39, −9], mg/dl). We found significant median differences across matched pairs in maximum serum C-reactive protein (8.9, 95% CI [4.6, 13.2], mg/dl), minimum albumin (−4.2, 95% CI [−6.7, −1.7], g/l), decrease in albumin (−3.9, 95% CI [−7.6, −0.2], g/l), and lowest cholinesterase levels (−0.72, 95% CI [−1.05, −0.39], U/l). Subsequently, more pronounced decreases in serum total cholesterol levels and lower minimum total cholesterol levels during critical care unit hospitalizations may be a risk factor for CIP.

Effects of Season, Productive State, Age and Agro-ecology on Blood Biochemical Characteristics of Dromedary Camels (Camelus dromedarius) in Natural Browsing Environment

Background: Blood biochemistry and reference intervals assist in distinguishing between healthy and productive camels as well as providing information for nutritional conditions, evaluation and monitoring when they are allowed to browse naturally; nevertheless, these intervals are frequently collected from animals of varying ages. The nutritional condition and biochemical markers of dromedary camels in pastoral systems in southern Ethiopia were investigated in this study, which took season, animal status, age and environmental variables into consideration. Methods: A total of 36 camels were divided into three groups based on their age ( greater than 8 years, 5-8 years, or less than 5 years) and productive state (milking, pregnant and young) in two environments (two herds in arid and semi-arid areas). Blood samples were collected from animals’ neck jugular veins, centrifuged and frozen for analysis. The samples were centrifuged (3000 rpm for 10 min) immediately after their arrival at the laboratory. Serum concentrations of glucose, protein, urea, creatinine, triglycerides and cholesterol were measured using spectrophotometry. Result: This study shows that glucose (91.33+7.30 mg/dl), total protein (7.17+0.15 mg/dl) and triglyceride (75.28+5.38 mg/dl) concentrations were significantly higher (P less than 0.05) during the rainy season, whereas urea (32.06+1.18 mg/l) and creatinine levels were significantly higher during the dry season. The study reveals increased glucose, total protein and triglyceride concentrations in camels during the rainy season, while urea and creatinine levels were higher during the dry season. Arid camels had lower serum concentrations of total protein and urea. Milking and pregnant camels had lower total serum protein, triglyceride and cholesterol levels.

Phytochemistry, Ethnobotanical uses and Pharmacology of Borago officinalis Linn: A Review

The plant Borage (Borago officinalis L.) family-Boraginaceae, also known as "starflower" is an annual herb originating in Syria, but naturalized throughout the Mediterranean region, as well as Asia Minor, Europe, North Africa, and South America. Aims of the Review The purpose of this study is to provide comprehensive scientific information on the phytochemistry, traditional uses and pharmacological activities of Borago officinalis L. The plant is reputed as hepatoprotective, gastrointestinal, respiratory anxiolytic, antispasmodic, antihypertensive, antipyretic, aphrodisiac, demulcent, diuretic and is also considered useful to treat asthma, bronchitis, cramps, palpitations and kidney ailments. Borage oil has been reported to lower serum cholesterol, phospholipids and triglyceride levels and increases the levels of 6 polyunsaturated fatty acids in the plasma, liver, aorta and renal artery tissues and ω -3 polyunsaturated fatty acids (PUFAs) obtained from Borago officinalis L. Dietary use of borage oil exhibited immuno -modulatory, cytotoxic and free radical scavenging activities. Borage has gained importance, due to the occurrence of high levels of g-linolenic acid in its seed oil. Flavonoids and phenolic compounds were the important essential oils in this plant and no have tannin. Borago officinalis extracts demonstrated excellent antioxidant properties and these effects were attributed to their phenolic constituents. Few studies examining Iron, Copper, Zinc and Manganese fertility in Borage have been conducted, but they are not specific to the medicinal use of this plant.

Drug repurposing by in silico prediction of cyclizine derivatives as antihyperlipemic agents.

Cardiovascular diseases are the primary factor for increased mortality rates around the world. Atherosclerosis brought on by high serum cholesterol can result in coronary heart disease (CHD). The risk of CHD is markedly reduced by lowering serum cholesterol levels. Scientists across the world are inventing new treatment regimens for lowering blood lipid levels. In this work, we repurposed the already established drugs, i.e., cyclizine derivatives as antihyperlipidemic agents. The repurposing was done based on the similarity of the selected cyclizine derivatives with the already established antihyperlipidemic drug, fenofibrate. Computational studies were performed and the 16 cyclizine derivatives docked against PPAR. alpha scored higher than fenofibrate. Lifarizine and medibazine outperform fenofibrate inmmgbsa. Fenofibrate, etodroxizine, meclizine, and cinnarizine had similar mmgbsa scores. The ADME properties of these compounds were performed and from that etodroxizine and levocetirizine were found to have better properties. The computational studies were performed using the Schrodinger software, maestro 12.8. The "Protein Preparation Wizard" module in the Maestro panel was used to create the protein structure and OPLS4 force field was used for energy minimization. The maestro builder panel's "Ligprep", "Receptor Grid Generation" and "Ligand Docking" modules were then used to prepare ligands, receptor grids and to perform docking respectively. MMGBSA was performed on the "prime MMGBSA" segment. Using the "Qikprop" setting in the maestro panel, a number of ADMET properties were predicted, and the program was run in default mode using vsgb as the solvation model.

A synbiotic made of an autochthonous Enterococcus durans strain and microbial polysaccharides improves broiler chicken health

PurposeThe gastrointestinal tract (GI) of organically fed desi chickens fosters a microbiota that can exclude pathogens and be potentially probiotic for improving the gut health of commercial chickens. MethodsA panel of strains were selectively cultured from desi chicken intestine and screened for their antagonism towards specific pathogens. Treating the culture free supernatant (CFS) of such strains with NaOH and proteases gives a picture of the antibacterial compound's biochemistry and determining its minimum inhibitory concentration (MIC) provides a measure of potency. The most strongly antagonistic strains were tested in vitro for surviving the chicken GIT. Safety was examined using mucin degradation, gelatin liquefaction, hemolysis, antibiotic susceptibility and biogenic amine production. An in vivo trial was done on young male Ross chickens to evaluate the performance of a bespoke synbiotic formulation comprising of an Enterococcus durans strain (1x108 CFUg−1) with prebiotics Dextran or Levan (0.1% w/v) and with both and assessing its impact on broiler gut microbiota, body and carcass weight, histopathology of organ tissues, and biochemical markers. ResultsA panel of Enterococcus spp. (NPL1315-NPL1334) was obtained and the selected strains (NLP-1319, 20, 24, 27, 34) showed good bile, acid and phenol survival, and cell surface hydrophobicity but not autoaggregation and none of them were deemed unsafe. The synbiotic-fed chickens were significantly heavier, with lowered serum cholesterol, triglycerides and glucose levels and a lesser load of pathogens than the controls. ConclusionDesi chicken intestine can be a viable source of probiotics with good antagonistic potential capable of replacing antibiotics in poultry feed.

Design, optimization, and in vivo evaluation of invasome-mediated candesartan for the control of diabetes-associated atherosclerosis

Atherosclerosis is an inflammatory disease characterized by the accumulation of arterial plaque. Diabetes mellitus stands out as a major risk factor for atherosclerosis. Candesartan is a potent angiotensin II receptor antagonist that enhances arterial blood flow and reduces insulin resistance. However, oral candesartan has limited activity because of its low bioavailability, water solubility, hepatic first-pass degradation, and efficacy. The current study aims to develop nasal candesartan-loaded invasome (CLI) drops to improve candesartan’s permeation, release, and bioavailability as a potential treatment for diabetes-associated atherosclerosis. Design expert software was used to prepare various CLI formulations to determine the impact of the concentrations of ethanol, cineole, and phospholipid. The desirability index was used to estimate the optimized formulation composition to maximize entrapment efficiency and minimize vesicle size. The optimized formulation had a 1% ethanol concentration, a 1.5% cineole concentration, and a 2.32% phospholipid concentration. The selected optimized formulation was then tested in a rat model of diabetes and atherosclerosis to evaluate its activity. The results showed that nasal CLI drops significantly raised serum HDL levels by a ratio of 1.42 and lowered serum glucose, cholesterol, triglycerides, LDL, and VLDL levels by 69.70%, 72.22%, 36.52%, 58.0%, and 65.31%, respectively, compared with diabetic atherosclerotic rats, throwing an insight on the potential for promising anti-diabetic and anti-atherosclerotic activities. Additionally, atherosclerotic lesions were improved in rats treated with CLI, as shown in histopathology. In conclusion, the results of this investigation showed that treatment with nasal CSN-loaded invasome formulation drops prevented the initiation and progression of diabetes-associated atherosclerosis.Graphical

Pathophysiology and Treatment of Lipid Abnormalities in Cerebrotendinous Xanthomatosis: An Integrative Review.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder caused by pathogenic variants in CYP27A1, leading to a deficiency in sterol 27-hydroxylase. This defect results in the accumulation of cholestanol and bile alcohols in various tissues, including the brain, tendons and peripheral nerves. We conducted this review to evaluate lipid profile abnormalities in patients with CTX. A search was conducted in PubMed, Embase and the Virtual Health Library in January 2023 to evaluate studies reporting the lipid profiles of CTX patients, including the levels of cholestanol, cholesterol and other lipids. Elevated levels of cholestanol were consistently observed. Most patients presented normal or low serum cholesterol levels. A decrease in chenodeoxycholic acid (CDCA) leads to increased synthesis of cholesterol metabolites, such as bile alcohols 23S-pentol and 25-tetrol 3-glucuronide, which may serve as surrogate follow-up markers in patients with CTX. Lipid abnormalities in CTX have clinical implications. Cholestanol deposition in tissues contributes to clinical manifestations, including neurological symptoms and tendon xanthomas. Dyslipidemia and abnormal cholesterol metabolism may also contribute to the increased risk of atherosclerosis and cardiovascular complications observed in some CTX patients.

Factors Associated with In-Hospital Mortality in Elderly Internal Medicine Patients with Nasogastric Tube Feeding.

To evaluate demographic, clinical, and laboratory variables, and their associations with in-hospital mortality, among elderly internal medicine patients with nasogastric tube (NGT) feeding. Demographic, clinical, and laboratory data were collected retrospectively for 129 patients aged ≥80 years who initiated NGT feeding during their hospitalization in internal medicine wards. The data were compared between survivors and non-survivors. Multivariate logistic regressions were performed to identify the variables most significantly associated with in-hospital mortality. The in-hospital mortality rate was 60.5%. Compared to survivors, non-survivors more often presented with pressure sores (P=0.005) and lymphopenia (P<0.001), were more often treated with invasive mechanical ventilation (P<0.001), and less often underwent geriatric assessment (P<0.001). Non-survivors demonstrated higher mean levels of C-reactive protein, and lower mean values of serum cholesterol, triglycerides, total protein, and albumin (P<0.001 for all comparisons). On multivariate analysis, the following variables were most significantly associated with in-hospital mortality in the entire cohort: the presence of pressure sores (odds ratio [OR], 4.34; 95% confidence interval [CI], 1.68-11.48; P=0.003) and lymphopenia (OR, 4.09; 95% CI, 1.51-11.08; P=0.006), and serum cholesterol (OR, 0.98; 95% CI, 0.96-0.99; P=0.003). Among elderly acutely ill patients who initiated NGT feeding during hospitalization, in-hospital mortality was extremely high. The factors most strongly associated with in-hospital mortality were the presence of pressure sores and lymphopenia, and lower serum cholesterol levels. These findings may provide useful prognostic information for decision-making regarding initiation of NGT feeding in elderly hospitalized patients.
