SYNERGISM BETWEEN PROBIOTICS AND HERBS TO MANAGE TYPE 2 DIABETES IN RATS

Objective: This study aims to explore the adjuvant effect of multi-strain probiotics with either saffron, cardamom, ginger, or cinnamon herbs to achieve synergistic management for controlling type 2 diabetes (T2D). Methods: Eighty-eight adult male, Wistar rats were used. Eight rats were kept as healthy control. Eighty rats were used to induce type 2 diabetic rats (T2DR) and were randomly assigned to ten groups. One group was an offer to 0.2 ml multi-strain probiotics orally. The rest of T2DR were gavage with 100 mg/kg aqueous extract of saffron, cardamom, ginger, or cinnamon without or with 0.2 ml multi-strain probiotics orally. Bodyweight gain (BWG), and feed efficiency ratio (FER) were recorded. Determination of oral glucose tolerance test (OGTT), serum insulin, C-peptide, HDL, LDL, HDL/total cholesterol ratio were performed. Serum antioxidant activity, Th1and Th2 cytokines and histopathology of the pancreas were done. Results: Comparable with T2DR, solely multi-strain probiotics or with herbs caused a significant reduction in BWG (P<0.05). Groups fed saffron, cardamom, and ginger and enriched with multi-strain probiotic showed significant improvement in OGTT, serum insulin, C-peptide and lipid abnormalities (P<0.05) compared to T2DR. Besides, they had antioxidant and anti-inflammatory effects. The group received ginger alone exerted anti-hyperglycemia and anti-inflammatory effects. However, cinnamon had a moderate anti-diabetic effect and solely probiotics did not show a significant benefit for all parameters except BWG. Conclusion: Cardamom, saffron, and ginger enriched with multi-strain probiotics achieve a synergistic relationship for managing T2D. This finding exhibits a possible new hypothesis to manage diabetes that needs further study

Development of novel adsorbent for industrial wastewater treatment

The main objective of this research project is to perform some experimental procedures to inform the ability of the novel adsorbent used in this project. The chemical modification of the adsorbent is the chemical oxidation of pure powder chitosan using some specific redox pairs which are potassium dichromate and sodium bisulphite. After preparing the modified chitosan, there are some parameters that must be discussed during the adsorption process. The first parameter is the time parameter, showing experimentally the optimum time for adsorption under certain conditions by collecting values of absorbance and concentration of thymol blue adsorbed after the process from the spectrophotometer showing that the optimum time is 120 minutes. While for the optimum pH experiment, it is shown that optimum pH is 4, 0.5% v/v is optimum concentration, and 0.05 grams is the optimum dose for the adsorbent. Then after computing these conditions and values of absorbance, some calculations and classifications are done to show the reaction kinetics and isotherm classification of the process. By performing some equations using mathematical rules it is provided that the reaction is not a first order reaction, showing by calculations and graphs that the reaction is a second order reaction. Also, to know the classification of the process other mathematical relations are done calculating slope and R2 to show whether the process reaction is a Langumir or Frendulish, showing that the reaction process is a Frendulish process having a greater value of R2

Novel Adsorbent For Industrial Wastewater Treatment Applications

In this study, the hydroxyapatite powder is investigated for both of methylene blue and thymol blue in aqueous solution. The physical and chemical properties of the adsorbent were evaluated systematically using the different techniques including Microsoft Excel programming, linear regression model and also the coefficient of determination. Batch adsorption experiments were conducted to determine the effect of contact time, solution pH, initial dye concentrations, and also the adsorbent dosage on adsorption. The adsorption kinetic parameters confirmed the better fitting of pseudo-second order kinetic model for both of methylene blue and thymol blue. The isotherm data of methylene blue and thymol blue could be well described by the Freundlich isotherm model which means the adsorption is multilayer adsorption with non-uniform distribution of adsorption heat and affinities over the heterogeneous surface. The maximum adsorption capacity (KF) of methylene blue and thymol blue is found to be 0.2736 (L/mg) and 11.18407 (L/mg) respectively. The high specific surface area and the porous structure with some acidic functional groups on the surface were obviously responsible for high dyes adsorption onto hydroxyapatite (HA). Adsorption kinetics data were modeled with the application of Pseudo first order, Pseudo second order and Intraparticle diffusion models. The results revealed that the Pseudo second order model was the best fitting model. Which means that, the adsorption mechanism followed two stages in which the first one was fast and the other was slower step. Which means the adsorption of dye molecules was limited by intra particle diffusion and film diffusion, as well as the adsorption rate in both of adsorption system are depends only on the slower step. The Boyd plot exposed that the intra-particle diffusion was the rate controlling step of the adsorption process of both of methylene blue and thymol blue molecules by HA powder. However, the adsorption of methylene blue molecules (basic solution) using of HA as adsorbent particles is found to be extremely preferable than thymol blue molecules

Effect of different polishing techniques on surface roughness and bacterial adhesion of three glass ionomer-based restorative materials : in vitro study

Although many reports concluded that polishing of glass ionomers is crucial for smoother surface and limiting the adhesion of cariogenic bacteria, there is no specific surface treatment protocol recommended. A novel material in the same category was released recently claimed to have surface smoothness comparable to resin composite and bacterial adhesion less than other types of glass ionomers. In this study, different polishing systems were tested with three glass ionomers one of them is the novel material to find the most appropriate polishing protocol. Objectives: To evaluate and compare the surface roughness and bacterial adhesion to resin modified glass ionomer, bioactive ionic resin and conventional glass ionomer restorative materials after different polishing protocols in vitro. The materials tested includes resin modified glass ionomer, bioactive ionic resin, and conventional glass ionomer. The polishing protocols were divided into four groups: group 1 = (Mylar matrix strips, Control), group 2 = (one-step, PoGo), group 3 = (two-step, Prisma Gloss) and group 4 = (three-step, Sof-Lex). From each material, eleven cylindrical specimens were prepared for each group according to the manufacturers? instructions. The surface roughness for all specimens was measured using atomic force microscope in tapping mode. the same specimens were subjected to bacterial adhesion testing after being coated with artificial saliva. Data were analyzed with two-way analysis of variance followed by Post hoc multiple comparisons. The highest Ra and S. mutans adhesion values were recorded for all materials in two-step group. The lowest Ra and S. mutans adhesion values were seen in one-step and three step groups. One-step polishing system was more effective and may be preferable for polishing of the three studied glass ionomer-based materials compared to two-step and three-step systems

Texture evaluation of whey protein concentrate incorporated ice cream by Back Extrusion technique

Back extrusion technique was employed to evaluated texture properties of partial substituted whey protein concentrate (WPC) with milk solids not fat (1, 2, 3 and 4%) in ice cream formula. There was no remarkable effect of adding WPC on total solids or fat %. Total protein increased, while ash, and lactose content were significantly decreased. Back-extrusion results represented a decrease in hardness values of resultant ice cream, while, during storage, there was a slight increase. Energy input values decreased by increasing substitution levels of WP. Although, energy output inversely correlated with substitution levels of WP it correlated with storage period indicating a strong structure for stored ice cream. Load at target deformation (50%) applied to the samples when fresh and after 14 days storage showing decreased values proportional to increasing substitution levels of WP. The resilience showed decreased ratio indicating more visco-elastic properties in fresh ice cream. The recovered height and deformation increased with increasing substitution levels of WP and storage period. Therefore, more sticking properties were obtained in resultant ice cream. Adhesive force decreased significantly with increasing substitution levels of WP and storage period. Adhesiveness values were significantly higher in all treatments than control. The texture of the ice cream became smoother by replacing milk solid not fat with WPC up to 3%. From the data obtained, it could be recommended that ice cream can be produced with high quality by substituting milk solid not fat with WPC up to 3%

Efficient, Recyclable, and Heterogeneous Base Nanocatalyst for Thiazoles with a Chitosan-Capped Calcium Oxide Nanocomposite

Calcium oxide (CaO) nanoparticles have recently gained much interest in recent research due to their remarkable catalytic activity in various chemical transformations. In this article, a chitosan calcium oxide nanocomposite was created by the solution casting method under microwave irradiation. The microwave power and heating time were adjusted to 400 watts for 3 min. As it suppresses particle aggregation, the chitosan (CS) biopolymer acted as a metal oxide stabilizer. In this study, we aimed to synthesize, characterize, and investigate the catalytic potency of chitosan–calcium oxide hybrid nanocomposites in several organic transformations. The produced CS–CaO nanocomposite was analyzed by applying different analytical techniques, including Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and field-emission scanning electron microscopy (FESEM). In addition, the calcium content of the nanocomposite film was measured using energy-dispersive X-ray spectroscopy (EDS). Fortunately, the CS–CaO nanocomposite (15 wt%) was demonstrated to be a good heterogeneous base promoter for high-yield thiazole production. Various reaction factors were studied to maximize the conditions of the catalytic technique. High reaction yields, fast reaction times, and mild reaction conditions are all advantages of the used protocol, as is the reusability of the catalyst; it was reused multiple times without a significant loss of potency

A novel approach toward skin cancer classification through fused deep features and neutrosophic environment

Variations in the size and texture of melanoma make the classification procedure more complex in a computer-aided diagnostic (CAD) system. The research proposes an innovative hybrid deep learning-based layer-fusion and neutrosophic-set technique for identifying skin lesions. The off-the-shelf networks are examined to categorize eight types of skin lesions using transfer learning on International Skin Imaging Collaboration (ISIC) 2019 skin lesion datasets. The top two networks, which are GoogleNet and DarkNet, achieved an accuracy of 77.41 and 82.42%, respectively. The proposed method works in two successive stages: first, boosting the classification accuracy of the trained networks individually. A suggested feature fusion methodology is applied to enrich the extracted features’ descriptive power, which promotes the accuracy to 79.2 and 84.5%, respectively. The second stage explores how to combine these networks for further improvement. The error-correcting output codes (ECOC) paradigm is utilized for constructing a set of well-trained true and false support vector machine (SVM) classifiers via fused DarkNet and GoogleNet feature maps, respectively. The ECOC’s coding matrices are designed to train each true classifier and its opponent in a one-versus-other fashion. Consequently, contradictions between true and false classifiers in terms of their classification scores create an ambiguity zone quantified by the indeterminacy set. Recent neutrosophic techniques resolve this ambiguity to tilt the balance toward the correct skin cancer class. As a result, the classification score is increased to 85.74%, outperforming the recent proposals by an obvious step. The trained models alongside the implementation of the proposed single-valued neutrosophic sets (SVNSs) will be publicly available for aiding relevant research fields

EFFECT OF DIFFERENT GROUP SIZE ON THE PRODUCTIVE PERFORMANCE OF GROWING RABBITS

This study was carried out to investigate the effect of different group’s size on productive performance of growing rabbits. A total number of 108 APRI weaning rabbits, their average initial body weight were 560±10g. Animals were assigned to two groups: The 1st group housed by 4 rabbits in cage 60 cm2, while the 2nd group housed by 8 rabbits in cage 120 cm2. During the experimental period live body weight(g), daily feed intake(g) and mortality rate (%)  were recorded and daily body weight gain(g) and feed conversion ratio(FCR) were calculated at 5, 8, 10 and 12 weeks of age. After the end of the experiment (12 wk) 36 rabbits were randomly taken and slaughtered to calculate the measure carcass traits. These include total giblet (g), cervix part (%), front quarters (%), intermediate part (%), hind quarter (%) and the dressing weight. Also the economical efficiency (EE%) was calculated. Results indicated that: the average live body weight (LBW), daily weight gain (DWG) and daily feed intake (DFI) were not significantly influenced by different group size. The best DWG values were recorded for the group 2 (8 rabbits/ cage), by around 2.5% during the whole fatting period (5-12 wks). Daily feed intake was lower in group 2 than group 1 by around 6.20%, 2.00%, 0.31% and 2.83% at 5, 8, 10 and 12 weeks of age, respectively. Data revealed significant improvements in FCR for rabbits in group2 (P<0.05) than group1 for the period 5-8 and during the whole growing period 512 weeks. The mortality rate was lower in group 2  than in group 1. The best dressing weight value was recorded for the group 2 by around 9.2%.The economical efficiency (EE %) was improved in group 2. It is concluded that, increasing number of rabbits to 8 rabbits in cage could decrease the mortality %, increase the dressing weight that also lead to increase the economical efficiency

Longitudinal Studies of Wearables in Patients with Diabetes: Key Issues and Solutions

Glucose monitoring is key to the management of diabetes mellitus to maintain optimal glucose control whilst avoiding hypoglycemia. Non-invasive continuous glucose monitoring techniques have evolved considerably to replace finger prick testing, but still require sensor insertion. Physiological variables, such as heart rate and pulse pressure, change with blood glucose, especially during hypoglycemia, and could be used to predict hypoglycemia. To validate this approach, clinical studies that contemporaneously acquire physiological and continuous glucose variables are required. In this work, we provide insights from a clinical study undertaken to study the relationship between physiological variables obtained from a number of wearables and glucose levels. The clinical study included three screening tests to assess neuropathy and acquired data using wearable devices from 60 participants for four days. We highlight the challenges and provide recommendations to mitigate issues that may impact the validity of data capture to enable a valid interpretation of the outcomes

Zaštitno djelovanje selenija protiv prekomjerne ekspresije apoptotskih gena povezanih s karcinomom u štakora izloženih o-krezolu

Cresols are monomethyl derivatives of phenol frequently used as solvents and intermediates in the production of disinfectants, fragrances, pesticides, dyes, and explosives, which is probably why they are widely distributed in the environment. General population may be exposed to cresols mainly through inhalation of contaminated air. In this study we evaluated the toxicological effects of o-cresol on differential gene expression profile of rat liver and prostate. Experiments were conducted on 80 male rats, 60 of which were exposed to o-cresol (1.5 g kg-1, 5 g kg-1, or 15 g kg-1) through feed for 8 weeks. Three groups of rats were supplemented with 0.1 mg kg-1 selenium (Se, in the form of, sodium selenite) in addition to o-cresol to evaluate its effectiveness against o-cresol toxicity. Control group received neither o-cresol nor Se, while one group received Se alone. Survival was similar between the exposed and control animals. Rats exposed to 15 g kg-1 of o-cresol showed a 16 % loss in body weight by the end of the study, which may have been related to o-cresol making feed unpalatable at this concentration. Liver and prostate tissue samples were collected at the end of the treatment. mRNA analysis revealed that apoptotic genes (CYP3A, COX-2, PPARγ, BAX, BCL2, AKT-1, and PKCα) related to cancer were up-regulated in liver and prostate tissues isolated from groups exposed to 5 g kg-1 and 15 g kg-1 o-cresol in comparison to control. Changes in gene expression profile were prevented when rats were supplemented with Se. The exact mechanisms underlying its protective effect remain to be clarified by future studies.Krezoli su monometilni derivati fenola koji se često rabe kao otapala te kao posrednici u proizvodnji dezinfekcijskih sredstava, mirisa, pesticida, boja i eksploziva. Otuda i njihova rasprostranjenost u okolišu. Opća je populacija izložena krezolima uglavnom putem zraka. U ovome se toksikološkom istraživanju ocijenilo djelovanje o-krezola, jednoga od tri krezolova izomera, na ekspresiju gena u tkivima jetre i prostate mužjaka štakora. Istraživanje je provedeno na 80 mužjaka, od kojih je 60 tijekom osam tjedana bilo izloženo o-krezolu (1,5 g kg-1, 5 g kg-1, odnosno 15 g kg-1) preko krmiva. Tri skupine štakora primale su uz o-krezol nadomjestak selenija u dozi od 0.1 mg kg-1 (Se, u obliku natrijeva selenita) radi ocjene njegove djelotvornosti protiv toksičnosti o-krezola. Kontrolna skupina nije primala ni o-krezol ni Se, dok je jedna skupina primala samo Se. Preživljenje je bilo podjednako u svih skupina životinja. Štakori izloženi najvišoj dozi o-krezola (15 g kg-1) imali su 16 % manju tjelesnu masu od kontrolne skupine na kraju ispitivanja, što može biti povezano s lošim okusom krmiva zbog primjese visoke doze o-krezola. S istekom osmotjednoga izlaganja o-krezolu životinje su eutanazirane te su prikupljeni uzorci tkiva jetre i prostate. Analiza m-RNA pokazala je značajno povišenu ekspresiju apoptotskih gena CYP3A, COX-2, PPARγ, BAX, BCL2, AKT-1 i PKCα, koji su povezani s nastankom karcinoma u skupinama štakora izloženim o-krezolu (5 g kg-1 i 15 g kg-1 u odnosu na kontrolu. Ova je prekomjerna ekspresija poništena u štakora koji su primali selenij. Još nisu jasni mehanizmi iza ovoga zaštitnog djelovanja, na što će odgovoriti buduća istraživanja
