Biological Evaluation of Bioactive Compounds of Selaginella plana in Treating Diabetic Neuropathy

Introduction: The study is aimed to assess the plant bioactive compounds of Selaginella plana in treating diabetic neuropathy. The plant components were assessed using ethanol as the solvent. Method: A phytochemical screening was conducted to ascertain the existence of secondary metabolites in the plant extracts. The efficacy of plant extract against neuropathic pain was determined using plantar test and Von Frey filament stimulation. Biochemical tests were performed to determine the level of SGOT, SGPT, ALP, HDL, CHO, LDL, Creatinine and Urea. The percentage yield of ethanol and aqueous extract was 19.22 g and 15.76 g, respectively. Result: The ethanolic extract showed presence of most of the phytoconstituents like alkaloids, flavonoids, carbohydrates, tannins, phytosterols, glycosides, proteins, and gum. Thus, ethanolic extract was used for further studies. In contrast to disease induced rats, rats given the extract chronically had a considerably shorter hind paw withdrawal latency. In STZ-induced diabetic rats, the mechanical withdrawal threshold dramatically reduced mechanical allodynia after 7 days by a dose of 400 mg/kg. Conclusion: The major findings of the study demonstrated that STZ-induced diabetic rats administered leaf extract had reduced neuropathic pain. It can be concluded that S. plana may be used as an alternative drug in the treatment of diabetic neuropathy.

Mechanistic exploration of COVlD-19 antiviral drug ritonavir on anaerobic digestion through experimental validation coupled with metagenomics analysis

Aggregation of antiviral drugs (ATVs) in waste activated sludge (WAS) poses considerable environmental risk, so it is crucial to understand the behavior of these agents during WAS treatment. This study investigated the effects of ritonavir (RIT), an ATV used to treat human immunodeficiency virus infection and coronavirus disease 2019, on anaerobic digestion (AD) of WAS to reveal the mechanisms by which it interferes with anaerobic flora. The dosage influence results showed that methane production in AD of WAS decreased by 46.56 % when RIT concentration was increased to 1000 μg/kg total suspended solids (TSS). The AD staging test revealed that RIT mainly stimulated microbial synthesis of the extracellular polymeric substance (EPS), limiting organic matter solubilization. At 500 μg/kg TSS, RIT decreased CHO and CHON levels in dissolved organic matter by 23.12 % and 56.68 %, respectively, significantly reducing substrate availability to microorganisms. Metagenomic analysis of microbial functional gene sets revealed that RIT had greater inhibitory effects on protein and amino acid metabolism than on carbohydrate metabolism. Under RIT stress, methanogens switched from hydrogenotrophic and acetotrophic methanogenesis to methylotrophic and acetotrophic methanogenesis.

The Application of Spinal Manipulation Results in Alterations in Thalamic Neural Metabolite among Patients Experiencing Nonspecific Chronic Low Back Pain

Abstract Background: In patients diagnosed with nonspecific chronic low back pain (NCLBP), discernable discrepancies in pain perception have been observed. This study endeavors to assess alterations in left thalamic metabolites in patients with NCLBP following spinal manipulation, utilizing proton magnetic resonance spectroscopy (1H-MRS). Materials and Methods: A total of 16 individuals diagnosed with NCLBP and 16 healthy individuals volunteers of normal constitution (aged between 20 and 50 years) were recruited. All participants exhibited right-hand dominance. Before commencement of therapeutic intervention and at a 5-week interval thereafter, functional and radiological assessments were undertaken (Oswestry Disability Index, numerical rating scale, and 1H-MRS). The values were compared using independent and paired t tests. Results: Following spinal manipulation, the patients experienced notable reductions in pain and disability (P < 0.05). The treatment group demonstrated significant increases in N-acetyl aspartate (NAA), choline (Cho), myo-inositol (Mio), and glutamate and glutamine (Glx) in the left thalamus region post-treatment compared with the baseline measures (P < 0.05). Before treatment, NAA, Cho, Glx, and Mio levels were significantly lower in the left thalamus of the patients compared with healthy subjects (P < 0.05). However, no significant differences in terms of metabolites were observed between the healthy control group and the patients after the treatment. Conclusion: In patients presenting with NCLBP, spinal manipulation has been observed to exert an effect on the brain, thereby inducing changes in thalamic metabolites.

LIMA1 links the E3 ubiquitin ligase RNF40 to lipid metabolism

LIMA1 is a LIM domain and Actin binding 1 protein that acts as a skeleton protein to promote cholesterol absorption, which makes it an ideal target for interfering with lipid metabolism. However, the detailed regulation of LIMA1 remains unclear. Here, we identified that ring finger protein 40 (RNF40), an E3 ubiquitin ligase previously known as an epigenetic modifier to increase H2B ubiquitination, mediated the ubiquitination of LIMA1 and thereby promoted its degradation in a proteasome-dependent manner. Fraction studies revealed that the 1–166aa fragment of LIMA1 was indispensable for the interaction with RNF40, and at least two domains of RNF40 might mediate the association of RNF40 with LIMA1. Notably, treatment with simvastatin dramatically decreased the levels of CHO and TG in control cells rather than cells with overexpressed LIMA1. Moreover, RNF40 significantly decreased lipid content, which could be reversed by LIMA1 overexpression. These findings suggest that E3 ubiquitin ligase RNF40 could directly target LIMA1 and promote its protein degradation in cytoplasm, leading to the suppression of lipid accumulation mediated by LIMA1. Collectively, this study unveils that RNF40 is a novel E3 ubiquitin ligase of LIMA1, which underpins its high therapeutic value to combat dysregulation of lipid metabolism.

Association of Age and Response to Methylphenidate HCL Treatment in Adult ADHD: A Proton Magnetic Resonance Spectroscopy Study.

This study investigated the age-dependent effects of methylphenidate (MPH) on brain metabolites including choline (Cho), N-acetyl aspartate (NAA) and creatine (Cr) levels in the dorsolateral prefrontal cortex (DLPFC), striatum, cerebellum, and anterior cingulate cortex (ACC) regions of the brain in adult patients with attention deficit hyperactivity disorder (ADHD). The study was included 60 patients with ADHD between the ages of 18 and 60 years. The patients were grouped with respect to their ages as follows: 18-24 years, 25-30 years, and 31 and over years. Levels of NAA, Cr and Cho in DLPFC, ACC, cerebellum and striatum were measured with magnetic resonance spectroscopy (MRS). Subjects were then given 10 mg of oral MPH and the same metabolite levels were measured 30 minutes apart. Twelve (20%) of the cases were female and 48 (80%) were male. The age distribution of the cases is as follows: 15 subjects between the ages of 18-24, 26 subjects between the ages of 25-30 and 19 subjects over the age of 30. NAA levels were higher after MPH in the DLPFC of the 18-24 age group (p = 0.016) and in the cerebellum of the 25-30 age group (p = 0.041). No increase in Cho and Cr levels was observed after treatment compared to before (p > 0.05). It is thought that treatment of MPH can be effective on metabolites in different brain regions and this effect can vary upon age adult ADHD patients. After MPH treatment, both the 18-24 age group (in the DLPFC) and the 25-30 age group (in the cerebellum) was detected significantly higher NAA levels compared to pre-treatment levels. This increase in NAA levels suggested that pharmacotherapy, especially at early ages, may be effective on neuronal damage.

Development and quality evaluation of novel biscuits by utilizing fruits and vegetables seed

Food supplementation is a topic of attention now since consumers are becoming more conscious of their nutritional needs. The purpose of this study was to create innovative biscuits utilizing fruit and vegetable seeds and to assess their quality. The right-shaped biscuits were prepared and baked at 170°C for 20 to 25 mins. There were six distinct varieties of biscuits made: control, date, jackfruit, bean, pumpkin, and mixed seed powder contained biscuits. When compared to other biscuits, the bean seed powder-incorporated biscuit gets a high overall acceptance score (7.88). The mixed seed powder incorporated biscuit had a sizable amount of moisture (4.70%) and ash (1.42%). Jackfruit (24.54%), pumpkin (18.46%), beans (9.03%), and date (74.19%) seed powder incorporated biscuits have quite significant levels of protein, fat, crude fiber, and total CHO. Biscuits containing jackfruit seed powder had relatively high WAC and bulk density (2.51% and 0.67%). The thickness, volume, density and spread ratio were relatively high in jackfruit (1.43 cm), mixed (18.58 cm3 ), date (0.55 g/cm3 ) and bean (4.74) seed incorporated biscuits respectively. The highest iron content was found in pumpkin seed-incorporated biscuits (0.41 mg/100 g). The mixed seed powder-incorporated biscuits had a high (95.06%) percentage of inhibition in antioxidant tests. According to the current study, replacing wheat powder in biscuits with fruit and vegetable seed powder up to 15% would boost the biscuit's nutritional content.

Sex-dependent effect of sublethal copper concentrations on de novo cholesterol synthesis in astrocytes and their possible links to variations in cholesterol and amyloid precursor protein levels in neuronal membranes

BackgroundCholesterol (Cho) is an essential lipophilic molecule in cells; however, both its decrease and its increase may favor the development of neurological diseases such as Alzheimer’s disease (AD). Although copper (Cu) is an essential trace metal for cells, the increased plasma concentration of its free form has been linked with AD development and severity. AD affects aged people, but its prevalence and severity are higher in women than in men. We have previously shown that Cu promotes Cho de novo synthesis in immature neurons as well as increased Cho in membrane rafts and Aβ levels in culture medium, but there are no results yet regarding sex differences in the effects of sublethal Cu exposure on Cho de novo synthesis.MethodsWe examined the potential sex-specific impact of sublethal Cu concentrations on de novo Cho synthesis in primary cultures of male and female astrocytes. We also explored whether this had any correlation with variations in Cho and APP levels within neuronal membrane rafts.ResultsFlow cytometry analysis demonstrated that Cu treatment leads to a greater increase in ROS levels in female astrocytes than in males. Furthermore, through RT-PCR analysis, we observed an upregulation of SREBP-2 and HMGCR. Consistently, we observed an increase in de novo Cho synthesis. Finally, western blot analysis indicated that the levels of ABCA1 increase after Cu treatment, accompanied by a higher release of radiolabeled Cho and an elevation in Cho and APP levels in neuronal membrane rafts. Importantly, all these results were significantly more pronounced in female astrocytes than in males.ConclusionsOur findings confirm that Cu stimulates Cho synthesis in astrocytes, both in a ROS-dependent and -independent manner. Moreover, female astrocytes displayed elevated levels of HMGCR, and de novo Cho synthesis compared to males following TBH and Cu treatments. This corresponds with higher levels of Cho released into the culture medium and a more significant Cho and APP rise within neuronal rafts. We consider that the increased risk of AD in females partly arises from sex-specific responses to metals and/or exogenous substances, impacting key enzyme regulation in various biochemical pathways, including HMGCR.

The diagnostic challenge of lack of choline level elevation on 1H-MR spectroscopy in grade II-III gliomas.

The accurate diagnosis of brain tumour is very important in modern neuro-oncology medicine. Magnetic resonance spectroscopy (MRS) is supposed to be a promising tool for detecting cancerous lesions. However, the interpretation of MRS data is complicated by the fact that not all cancerous lesions exhibit elevated choline (Cho) levels. The main goal of our study was to investigate the lack of Cho lesion /Cho ref elevation in the population of grade II-III gliomas. 89 cases of gliomas grade II and III were used for the retrospective analysis - glioma (astrocytoma or oligodendroglioma) grade II (74 out of 89 cases [83%]) and III (15 out of 89 cases [17%]) underwent conventional MRI extended by MRS before treatment. Histopathological diagnosis was obtained either by biopsy or surgical resection. Gliomas were classified to the group of no-choline elevation when the ratio of choline measured within the tumour (Cho lesion ) to choline from NABT (Cho ref ) were equal to or lower than 1. Significant differences were observed between ratios of Cho lesion /Cr lesion calculated for no-choline elevation and glial tumour groups as well as in the NAA lesion /Cr lesion ratio between the no-choline elevation group and glial tumour group. With consistent data concerning choline level elevation and slightly lower NAA value, the Cho lesion /NAA lesion ratio is significantly higher in the WHO II glial tumour group compared to the no-choline elevation cases ( p < 0.000). In the current study the results demonstrated possibility of lack of choline elevation in patients with grade II-III gliomas, so it is important to remember that the lack of elevated choline levels does not exclude neoplastic lesion.

A novel microtubule inhibitor promotes tumor ferroptosis by attenuating SLC7A11/GPX4 signaling

MP-HJ-1b is a novel microtubule inhibitor that we designed and reported previously. Ferroptosis is a newly identified type of nonapoptotic cell death induced by ferrous catalysis and lipid peroxidation. Here, transcriptomics, proteomics, and molecular docking analyses were combined to explore the novel effects of MP-HJ-1b on tumors. Both omics analyses suggested that MP-HJ-1b affects ribosomes, and we confirmed that it inhibits the ribosomal component proteins RPL35 and MRPL28. Colchicine was used as an analog, and the results showed that MP-HJ-1b and colchicine increased reactive oxygen species and malondialdehyde levels and decreased reduced glutathione levels, suggesting that they promoted ferroptosis in HeLa cells. Specifically, MP-HJ-1b downregulated SLC7A11 and GPX4 to enhance the classical pathway of ferroptosis, while colchicine upregulated LC3A/B-II and enhanced autophagy. Clinically, the serum concentrations of ferrous ions, reduced glutathione, and Hcy were higher in cervical cancer patients than in healthy individuals. ALT, AST, Cho, HDL-C, and LDL-C levels were decreased in the serum of patients. Our study expands understanding of the way MP-HJ-1b promotes cell death and enriches research on microtubule inhibitors in the ferroptosis field.

Elucidating the pharmacodynamic mechanisms of Yuquan pill in T2DM rats through comprehensive multi-omics analyses.

Background: Yuquan Pill (YQW) is a modern concentrated pill preparation of six herbs, namely, Ge Gen (Pueraria lobata Ohwi), Di huang (Rehmannia glutinosa Libosch.), Tian Huafen (Trichosanthes kirilowii Maxim.), Mai Dong (Ophiopogon japonicus (L. f.) Ker Gawl.), Wu Weizi (Schisandra chinensis (Turcz.) Baill.) and Gan Cao (Glycyrrhiza uralensis Fisch.). It is extensively used to treat type 2 diabetes-related glucose and lipid metabolism disorders. But what's the pharmacodynamic substance and how it works in the treatment of Type 2 diabetes mellitus (T2DM) are still unclear. Purpose: The purpose of this study is to determine the likely pharmacological components and molecular mechanism of YQW's intervention on T2DM by combining serum pharmacochemistry, network analysis and transcriptomics. Methods: The efficacy and prototypical components of blood entry were determined after oral administration of YQW aqueous solution to T2DM rats induced by high-fat feed and low-dose streptozotocin (STZ), and the key targets and pathways for these compounds to intervene in T2DM rats were predicted and integrated using network analysis and transcriptomics techniques. Results: In diabetic rats, YQW can lower TG, CHO, NO, and MDA levels (p < 0.05) while increasing HDL-C levels (p < 0.01), and protecting the liver and kidney. 22 prototype components (including puerarin, daidzein, 3'-methoxypuerarin, and liquiritigenin, among others) were found in the serum of rats after oral administration of YQW for 90min, which might be used as a possible important ingredient for YQW to intervene in T2DM rats. 538 YQW pharmacodynamic components-related targets and 1,667 disease-related targets were projected through the PharmMapper database, with 217 common targets between the two, all of which were engaged in regulating PI3K-Akt, MAPK, Ras and FoxO signal pathway. Finally, the mRNA expression profiles of liver tissues from rats in the control, model, and YQW groups were investigated using high-throughput mRNA sequencing technology. YQW can regulate the abnormal expression of 89 differential genes in a disease state, including 28 genes with abnormally high expression and 61 genes with abnormally low expression. Five common genes (Kit, Ppard, Ppara, Fabp4, and Tymp) and two extensively used regulatory pathways (PI3K-Akt and MAPK signaling pathways) were revealed by the integrated transcriptomics and network analysis study. Conclusion: The mechanism of YQW's intervention in T2DM rats could be linked to 22 important components like puerarin, daidzein, and glycyrrhetinic acid further activating PI3K-Akt and MAPK signaling pathways by regulating key targets Kit, Ppard, Ppara, Fabp4, and Tymp, and thus improving lipid metabolism disorder, oxidative stress, and inflammation levels in T2DM rats. On the topic, more research into the pharmacological ingredient foundation and mechanism of YQW intervention in T2DM rats can be done.

Evaluation of dietary rosemary leaf powder on growth, carcass composition and hemato-biochemical profiles of common carp (Cyprinus carpio) reared in cage system.

This study was conducted to evaluate the effect of rosemary (Rosmarinus officinalis) leaf powder (RLP) at 0.0% (control), 0.5%, 1% and 2% as a dietary supplement for eight weeks, on the growth performance, carcass composition and haemato-biochemical parameters. One hundred twenty common carp (Cyprinus carpio) (21.11±0.17g) were randomly distributed to 12 cages (0.2 m3) with three replicates for 56 days. The results showed that RLP-supplemented diets achieved significant enhancement of growth performance (FBW, SGR and WG) and feed utilization (FCR, FCE and PI) compared with a control group. In addition, TFI and PI were significantly improved in 0.5 and 2% RLP-supplemented groups. RLP had no significant effects on body composition except moisture content which was significantly increased in fish fed with a 1% supplemented diet and crude protein which was significantly decreased in fish fed with a 1% supplemented diet compared to the control diet. The results showed a significant increase in RLP-supplemented diets in RBC counts, LYM, MCV, hematocrit, total protein, albumin and globulin compared with the control group. WBC counts significantly increased in fish fed the 0.5 and 2% RLP diets, and hemoglobin significantly elevated in fish fed the 1% RLP diet. Glucose, GRA, MCH, MCHC and MPV were significantly decreased in the group fed the RLP diets compared with the control group. The AST, ALT, LDL, VLDL, CHO and TG levels showed a significant decrease in RLP compared to the control diet (P < 0.05), while ALP level fluctuated (P > 0.05). The urea and creatinine levels were higher in the RLP groups compared with the control (P < 0.05). Dietary RLP 1% increased lipase when compared to the control group. However, amylase levels in fish fed 0.5 and 1% RLP has significantly improved, while fish fed 2% RLP has significantly decreased when compared to the control diet. Overall, the results demonstrated that dietary RLP supplementation enhanced the growth and health status of common carp.

Association between nutritional status, body composition, and fitness level of adolescents in physical education in Casablanca, Morocco.

This study aims to analyze and compare dietary intake, as well as to examine the associations between energy intake in terms of macronutrients, body composition, and physical fitness (PF) specifically cardiorespiratory endurance (CE) among a sample of young adolescents aged 15 to 18 years, who participate in physical education and sports sessions in public schools in Casablanca, Morocco. A total of 311 participants, including 156 girls and 154 boys, were included in the study. Each participant maintained a food diary for 3 days during the same study week. Additionally, body composition measurements were taken using bioelectrical impedance analysis (BIA). The PF was assessed using the validated mini-Cooper test (6 min). The results show that the participants had an average total energy intake of 2386.7 ± 492.7 kcal. A significant difference was observed between boys and girls, with average energy intakes of 2468.8 ± 531.1 kcal and 2304.0 ± 437.0 kcal, respectively. These dietary intakes were significantly lower than their needs and nutritional recommendations. The associations of nutritional status, sex, body mass index (BMI) and physical fitness (PF) were tested and a positive correlation was observed following an adequate intake of carbohydrates (CHO) and proteins on Vo2max, while a negative association was observed with regard to Body fat for both sexes. Boys exhibit significantly better PF than girls (p < 0.01). Obese participants had the lowest PF and an unbalanced nutritional status, the adolescents with a normal weight p < 0.01 displayed a high level of PF compared to individuals in other weight categories. The PF is significantly associated with macronutrient intake status and body composition, especially BMI and BF. The Underweight, overweight, and obese students demonstrated poorer performance in physical fitness indices compared to normal-weight. Adolescents adhering to recommended CHO and protein intake levels tend to exhibit enhanced physical fitness. Implementing strategies to encourage students to maintain a balanced diet and engage in regular physical exercise is essential.

Comparing Hematological and Biochemical Profiles of Pregnant and Non-pregnant Barb Mares Raised in Tiaret, Algeria

Background: The pure-bred Barb horse is a beloved breed from the Great Maghreb. Despite the breed’s prominence in Algeria, no gestational hematological or biochemical research has been done on this breed. Objectives: This study aimed to compare the hematological and biochemical parameters of pregnant and non-pregnant Barb mares in the first, second, and third trimesters of pregnancy. Methods: From 12 pregnant and 6 non-pregnant mares, 102 venous blood samples were taken, and their glucose (Glu), cholesterol (Cho), triglycerides (TG), total protein (TP), urea (Urea), Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), iron (Fer), calcium (Ca), phosphorus (P), and ferric reducing ability of plasma (FRAP) were assessed as biochemical variables. Also, red blood cells, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration, white blood cells, and platelets were all measured as hematological variables. Results: The levels of ALP, ALT, GGT, and P decreased significantly throughout gestation, while Ca, TG, Fe, and Glu levels increased. AST concentrations decreased in the second and third trimesters, whereas Cho levels increased in the first and second trimesters. Urea levels increased significantly in the third trimester, and FRAP showed significant differences at different stages of pregnancy. Mean corpuscular hemoglobin concentration was significantly lower in the first and second trimesters, and hemoglobin values were significantly lower in the second trimester. The mean value of white blood cell count was slightly higher in late pregnancy, while platelet values significantly increased throughout all trimesters. Conclusion: The study provides valuable information on the changes in hematological and biochemical parameters during pregnancy in Barb mares. These findings can be used as a reference for future studies on the reproductive physiology of this breed.

Thalamic neurometabolite alterations in chronic low back pain: a common phenomenon across musculoskeletal pain conditions?

Recently, we showed that patients with knee osteoarthritis (KOA) demonstrate alterations in the thalamic concentrations of several metabolites compared with healthy controls: higher myo-inositol (mIns), lower N-acetylaspartate (NAA), and lower choline (Cho). Here, we evaluated whether these metabolite alterations are specific to KOA or could also be observed in patients with a different musculoskeletal condition, such as chronic low back pain (cLBP). Thirty-six patients with cLBP and 20 healthy controls were scanned using 1 H-magnetic resonance spectroscopy (MRS) and a PRESS (Point RESolved Spectroscopy) sequence with voxel placement in the left thalamus. Compared with healthy controls, patients with cLBP demonstrated lower absolute concentrations of NAA ( P = 0.0005) and Cho ( P < 0.05) and higher absolute concentrations of mIns ( P = 0.01) when controlling for age, as predicted by our previous work in KOA. In contrast to our KOA study, mIns levels in this population did not significantly correlate with pain measures (eg, pain severity or duration). However, exploratory analyses revealed that NAA levels in patients were negatively correlated with the severity of sleep disturbance ( P < 0.01), which was higher in patients compared with healthy controls ( P < 0.001). Additionally, also in patients, both Cho and mIns levels were positively correlated with age ( P < 0.01 and P < 0.05, respectively). Altogether, these results suggest that thalamic metabolite changes may be common across etiologically different musculoskeletal chronic pain conditions, including cLBP and KOA, and may relate to symptoms often comorbid with chronic pain, such as sleep disturbance. The functional and clinical significance of these brain changes remains to be fully understood.

Clustering patients with vascular cognitive impairment using quantitative magnetic resonance imaging data and a finite mixture model

AbstractBackgroundBlood‐brain barrier (BBB) leakage is a marker of vascular cognitive impairment and dementia (VCID). The advance of in vivo imaging enabled us to quantify the degree of BBB transfer rates in VCID patients. However, a consensus has not been reached on the role of BBB in the differential diagnosis of VCI subtypes. The objective of this work was to use neuroinflammatory and in vivo imaging data on BBB health to identify clusters of VCID patients with distinct underlying pathologies.MethodPatients included were on average 61 (SD = 15.94, M/F = 27/34) years old. The MRI data were collected by using a 1.5 Tesla Siemens Sonata scanner. Pixel‐by‐pixel BBB transfer rate (Ki) was calculated using Patlak compartmental analysis on dynamic contrast‐enhanced T1 maps. The mean BBB transfer rate was calculated for the brain section above the ventricular zone (sampled by six consecutive slices). MR Spectroscopy was used to investigate N‐Acetylaspartate (NAA), Creatine (Cr), and Choline (Cho) levels. Moreover, Active MMP3 data were used in patients clustering. Thirty‐eight patients enrolled in the study have all data for three entities; NAA, mean Ki, and active MMP3 used for clustering. A multi‐parametric model‐based classification method was used to blindly classify VCID data based on Ki, NAA, and active MMPs.ResultBBB leakage increased by age, which is more pronounced in patients diagnosed with cognitive impairment when compared with 17 controls, r2 = 0.060, P = 0.021. Statistical classifiers identified three clusters in VCID patients. Identified VCID clusters are similar to the distinction that was made on this VCID cohort based on the clinical scores and psychological entities that we have published earlier.ConclusionThe results suggest that a statistical combination of imaging and inflammatory attributes renders a tool to blindly separate VCID patients into distinct groups that may have different underlying pathology.

Body Fat-Reducing Effects of Whey Protein Diet in Male Mice.

This study investigated the mechanism of reducing body fat via whey protein diet. Pregnant mice were fed whey or casein, and their offspring were fed by birth mothers. After weaning at 4 weeks, male pups received the diets administered to their birth mothers (n = 6 per group). At 12 weeks of age, body weight, fat mass, fasting blood glucose (FBG), insulin (IRI), homeostatic model assessment of insulin resistance (HOMA-IR), cholesterol (Cho), triglyceride (TG), the expression levels of lipid metabolism-related genes in liver tissues and metabolomic data of fat tissues were measured and compared between the groups. The birth weights of pups born were similar in the two groups. Compared to the pups in the casein group, at 12 weeks of age, pups in the whey group weighed less, had significantly lower fat mass, HOMA-IR and TG levels (p < 0.01, p = 0.02, p = 0.01, respectively), and significantly higher levels of the antioxidant glutathione and the anti-inflammatory 1-methylnicotinamide in fat tissues (p < 0.01, p = 0.04, respectively). No differences were observed in FBG, IRI, Cho levels (p = 0.75, p = 0.07, p = 0.63, respectively) and expression levels of lipid metabolism-related genes. Whey protein has more antioxidant and anti-inflammatory properties than casein protein, which may be its mechanism for reducing body fat.

Neurometabolite levels in the brains of patients with autism spectrum disorders: A meta-analysis of proton magnetic resonance spectroscopy studies (N = 1501).

Evidence suggests that neurometabolite alterations may be involved in the pathophysiology of autism spectrum disorders (ASDs). We performed a meta-analysis of proton magnetic resonance spectroscopy (1H-MRS) studies to examine the neurometabolite levels in the brains of patients with ASD. A systematic search of PubMed and Web of Science identified 54 studies for the meta-analysis. A random-effects meta-analysis demonstrated that compared with the healthy controls, patients with ASD had lower N-acetyl-aspartate-containing compound (NAA) and choline-containing compound (Cho) levels and NAA/(creatine-containing compound) Cr ratios in the gray matter and lower NAA and glutamate + glutamine (Glx) levels in the white matter. Furthermore, NAA and gamma-aminobutyric acid (GABA) levels, NAA/Cr ratios, and GABA/Cr ratios were significantly decreased in the frontal cortex of patients with ASD, whereas glutamate (Glu) levels were increased in the prefrontal cortex. Additionally, low NAA levels and GABA/Cr ratios in the temporal cortex, low NAA levels and NAA/Cr ratios in the parietal and dorsolateral prefrontal cortices, and low NAA levels in the cerebellum and occipital cortex were observed in patients with ASD. Meta-regression analysis revealed that age was positively associated with effect size in studies analyzing the levels of gray matter NAA and white matter Glx. Taken together, these results provide strong clinical evidence that neurometabolite alterations in specific brain regions are associated with ASD and age is a confounding factor for certain neurometabolite levels in patients with ASD.

The anti-dyslipidemia property of saffron petal hydroalcoholicextract in cardiovascular patients: A double-blinded randomized clinical trial

Dyslipidemia is one of the most important risk factors of cardiovascular diseases (CVDs). Despite developments in pharmacological treatments for dyslipidemia there are several challenges. Recently some herbs highly considered to control dyslipidemia due to their low toxicity and high potency. In this study we investigated the effects of saffron petals on the lipid profile of dyslipidemia patients as well as several other biochemical blood factors. In this double blind, placebo controlled, clinical trial, we used systematic random sampling to divide 40 patients with at least two abnormalities in the following factors: (high-density lipoproteins (HDL) ≤40, low-density lipoproteins (LDL) ≥130, triglycerides (TG) ≥200, total cholesterol (Cho) ≥200), into 2 groups of 21 ones. At the end of the intervention period, serum lipid factors, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), urea, creatinin (CR) and fasting blood sugar (FBS) were measured and statistically compared with their values just before the intervention. We found that the saffron petal pills markedly (P<0.001) decreased the serum lipid levels of patients (TG, Cho and LDL) in the intervention group (113.81±12.93, 56.52±4.68 and 48.28±3.70) as compared to the placebo group (18.42±15.79, 4.57±4.40 and 7.38±3.54). Also, comparing the mean value of differences in two groups before and after the intervention showed significant reduction in TG (113.81±26), Cho (56.53±0.30) and LDL (48.28±4.30) levels (P<0.001). The saffron petal pills considerably reduced blood serum lipid profile and as well as urea and CR of dyslipidemia patients. So, this plant may be used as a potent phytomedicine for treatment and prevention of dyslipidemia and cardiovascular disorders. However, the results indicated that no statistical change was observed in the level of other biochemical blood factors such as ALT, AST, ALP and FBS.

Small Intestinal Digestive Functions and Feed Efficiency Differ in Different Pig Breeds

Small intestinal growth and health affect its digestion and absorption ability, while little information exists about the small intestinal morphology and function differences among the different pig breeds. Therefore, 90 healthy 35 days of age Taoyuan black (TB), Xiangcun black (XB), and Duroc (DR) pigs (30 pigs per breed) with similar body weight (BW) of the same breed were reared to 185 days of age to evaluate the potential relationship between feed efficiency and small intestinal morphology and function at 80, 125, and 185 days of age. The results show that the TB and XB pigs had lower initial and final BW, ADG, and ADFI and plasma CHO and LDL-C levels, whereas they had higher plasma LIP levels and jejunal trypsin, invertase, lactase, and maltase activities and higher DM, ADF, Tyr, Arg, and His digestibility at 80 days of age compared with the DR pigs. At 125 days of age, TB and XB pigs had lower apparent total tract digestibility and plasma CHO, HDL-C, LDL-C, and NH3 levels; XB pigs had lower DM and NDF digestibility, and TB pigs had higher jejunal lactase and maltase activities. At 185 days of age, TB and XB pigs had lower DM, EE, ADF, and GE digestibility, while having higher plasma ALT and UN levels; TB pigs had higher plasma AST level and jejunal chymase activity. Furthermore, the plasma free amino acid contents, small intestinal VH, and nutrient transporter expression levels differed at different ages. Therefore, the different pig breeds exhibited significantly different growth performance and small intestinal growth, mainly resulting from the differences in digestive enzymes and nutrient transporters in the small intestine.
