A Comparative Study of the Physicochemical Properties and Sensory Evaluation of Commercial Orange Juice sold in the Sulaimani Market with Local Preparation of Orange Juice

Orange juice is one of the most popular juices on the market. The bulk of accessible fruit drinks are synthetic and may include a number of toxic and poisonous substances those are harmful to customers' health. This study compares the physicochemical parameters, sugar content, organic acids, and sensory evaluation of commercial and fresh orange juice samples. The orange fruit was treated to produce fresh juice, which has 100% fruit content and no sugars or diluents. Packaged juice samples were obtained from a local store, and all testing was completed prior to the expiration of the juice's shelf life. Total solids, ash content, and pH were among the physicochemical properties investigated, with values ranging from 9.507–13.145%, 0.110–0.447%, and 4.360–5.970, respectively. Sugar content was observed to be in the ranges of 2.118–5.278, 2.641–4.317, and 2.563–4.184 g/100 ml for glucose, fructose, and sucrose individually. Organic acids (ascorbic, acetic, and citric acid) were found to have concentrations ranging from 25.170–43.981, 1.307–5.760 and 311–411.33 mg/100 ml separately. Sensory evaluation revealed a significant difference (p<0.05) between homemade and commercial orange samples. According to the acquired results and cluster analysis, there is a significant difference between handmade and commercial juice parameters. Commercial items include more sugar than fresh samples. The findings of this study contribute to our understanding of the nutrition and quality of commercial and homemade orange juice samples. Commercial samples are not recommended for regular intake due to the significant differences between artificial and fresh orange juice samples.

Biomass-derived carbon-coated WS2 core-shell nanostructures with excellent electromagnetic absorption in C-band

With the continuous advances in detection and early-warning technologies, stealth technologies have widely integrated in modern combat systems and armament research. The development of high-performance electromagnetic wave absorbing materials is important for electromagnetic stealth and shielding applications. Herein, biomass-derived carbon (BDC) from glucose is coated on the surface of folded and stacked WS2 nanosheets, forming WS2@BDC via a simple hydrothermal method and subsequent annealing carbonization. The amount of the BDC coating on the WS2 nanosheets is effectively controlled by the glucose solution concentration, and the electromagnetic wave (EMW) absorption performance in the low-frequency bands can be adjusted by the regulation of annealing temperature. The effective absorption band of WS2@BDC is shifted to a lower frequency region and the absorption performance is substantially enhanced, compared to those of pure WS2 nanosheets. The minimum reflection loss of WS2@BDC corresponding to 14 mL of glucose and a carbonization temperature of 800 °C can reach up to −51.40 dB at 5.52 GHz. The study provides a novel and facile method for improving the EMW absorption performance of WS2 in the low-frequency bands.

Beyond selective spinal anesthesia: A flow pattern analysis of a hyperbaric dye solution injected in a lower-density fluid.

Introduction:Spinal anesthesia is a technique performed since more than a century and the introduction of hyperbaric anesthetics allowed the anesthesiologists to be more selective when using this technique. The aim of this study is to show the in vitro flow patterns of a hyperbaric dye solution through 27 G Quincke and Sprotte spinal needles, injected at different speeds, in a lower-density fluid.Methods:A simulator was made using a gummy-like sponge and a disposable plastic urine glass, filled with saline solution, which has a similar density to cerebrospinal fluid (CSF). A hyperbaric dye solution was composed by mixing 3 ml of plain methylene blue with 1 ml of glucose 33%. We used both 27 G Quincke and Sprotte spinal needles to perform a bevel up and a bevel down injection with both slow (15 s) and fast (4 s) injection speed of 0.5 mL hyperbaric dye solution. All the injections were performed using a preset syringe pump and recorded by a camera.Results:The least selectivity was observed after a bevel up-fast injection through the 27 G Sprotte needle, followed by both bevel up and down fast injections through the 27 G Quincke needle. On the contrary, the best selectivity was observed after a bevel down-slow injection through the 27 G Sprotte needle, followed by both bevel up and down slow injections through the 27 G Quincke needle.Conclusion:When a 27 G Sprotte needle is used to inject a hyperbaric solution in a lower-density fluid-like CSF, the spread depends on both the bevel direction and the injection speed.

Antioxidative Potential, Antibiofilm Activity and Partial Chemical Characterization of Cultured Broth after Pleurotus ferulae Mycelium Cultivation

The purpose of the present study was to assess the antioxidant effect, antibiofilm activity, and partial characterization of the main groups of bioactive compounds of mushrooms, under the influence of the composition of the relevant culture environment and different fermentation parameters of the Pleurotus (P.) ferulae mushroom mycelium. One used five carbon sources (1.0 g, 2.5 g, and 5.0 g/100 mL), which included glucose, sorbitol, starch, lactose, and sucrose, and of the fermentation parameters, the variation was characteristic for temperature (21, 23, and 25�C), and the pH values varied between 5 and 8. Following a review of the data and the statistical correlation of results, an optimum level of culture environment was found: 2.5 g/100 mL of glucose, at a temperature of 21�C, and a pH value of 5. Under such circumstances, the antioxidant activity exhibited a certain correlation with the level of the primary bioactive compounds (phenolic acids, for instance), the antibiofilm effect against four bacterial strains, and the outcomes were confirmed by showing the essential statistical indices.

Myocardial Protection by Glucose-Insulin-Potassium in Moderate- to High-Risk Patients Undergoing Elective On-Pump Cardiac Surgery: A Randomized Controlled Trial.

Low cardiac output syndrome is a main cause of death after cardiac surgery. We sought to assess the impact of glucose-insulin-potassium (GIK) to enhance myocardial protection in moderate- to high-risk patients undergoing on-pump heart surgery. A randomized controlled trial was performed in adult patients (Bernstein-Parsonnet score >7) scheduled for elective aortic valve replacement and/or coronary artery bypass surgery. Patients were randomized to GIK (20 IU of insulin, 10 mEq of potassium chloride in 50 mL of glucose 40%) or saline infusion given over 60 minutes on anesthetic induction. The primary end point was postcardiotomy ventricular dysfunction (PCVD), defined as new/worsening left ventricular dysfunction requiring inotropic support (≥120 minutes). Secondary end points were the intraoperative changes in left ventricular function as assessed by transoesophageal echocardiography, postoperative troponin levels, cardiovascular and respiratory complications, and intensive care unit and hospital length of stay. From 224 randomized patients, 222 were analyzed (112 and 110 in the placebo and GIK groups, respectively). GIK pretreatment was associated with a reduced occurrence of PCVD (risk ratio [RR], 0.41; 95% confidence interval [CI], 0.25-0.66). In GIK-treated patients, the left systolic ventricular function was better preserved after weaning from bypass, plasma troponin levels were lower on the first postoperative day (2.9 ng·mL(-) [interquartile range {IQR}, 1.5-6.6] vs 4.3 ng·mL(-) [IQR, 2.4-8.2]), and cardiovascular (RR, 0.69; 95% CI, 0.50-0.89) and respiratory complications (RR, 0.5; 95% CI, 0.38-0.74) were reduced, along with a shorter length of stay in intensive care unit (3 days [IQR, 2-4] vs 3.5 days [IQR, 2-7]) and in hospital (14 days [IQR, 11-18.5] vs 16 days [IQR, 12.5-23.5]), compared with placebo-treated patients. GIK pretreatment was shown to attenuate PCVD and to improve clinical outcome in moderate- to high-risk patients undergoing on-pump cardiac surgery.

Comparative Study Between Conventional Fasting Versus Overnight Infusion of Lipid or Carbohydrate on Insulin and Free Fatty Acids in Obese Patients Undergoing Elective On-pump Coronary Artery Bypass Grafting. A Prospective Randomized Trial

Postoperative insulin resistance represents a major component of postoperative metabolic disorder. The authors compared the effects of preoperative infusion of lipid emulsion or carbohydrate to conventional preoperative fasting on postoperative insulin and free fatty acid (FFA) levels. A prospective randomized double-blinded study. Tertiary university hospital. Sixty-three patients undergoing coronary artery bypass grafting. Participants were randomized into 3 equal groups. Group G received 500 mL of glucose 10% (50 g glucose). Group L received 100 mL of 2% lipid emulsion (soybean 30%, medium chain triglycerides (TG) 30%, olive oil 25%, fish oil 15%, and 20 mg vitamin E). Group C fasted overnight except for clear fluids allowed until 4 hours preoperatively. Serum insulin at the start of infusion (T1), 1-hour preinduction (T2), on admission to the intensive care unit (T3), after 24 hours of admission (T4), and after 48 hours of admission (T5), and FFA at T1 and T2 were measured. Serum very-low-density lipoprotein (VLDL), serum TG, and blood sugar were all measured (T1-T4). Bypass time, ischemic time, need for inotropic support, and length of intensive care unit stay also were measured. At the end of infusion FFAs were significantly lower in the L group (1.1 ± 0.76 mg/dL) compared with G (1.64 ± 0.85 mg/dL) and C groups (1.48 ± 0.76 mg/dL). Insulin levels were significantly lower in the L group compared with levels in the G and C groups at T2, T3, and T4. Also, TG, VLDL, and random blood sugar levels decreased significantly at T2, T3, and T4 in the L group compared with the other 2 groups and compared with baseline value within the same group. Preoperative lipid infusion lowered postoperative FFA, insulin, TG, VLDL, and random blood sugar in obese patients undergoing coronary artery bypass grafting surgeries.

국내 담수퇴적물의 CODsed분석방법 평가: CODMn법과 CODCr법의 신뢰성 및 상관성 비교

In Korea, the chemical oxygen demand() in freshwater sediments has been measured by the potassium permanganate method used for marine sediment because of the absence of authorized analytical method. However, this method has not been fully verified for the freshwater sediment. Therefore, the use or modification of the potassium permanganate method or the development of the new analytical method may be necessary. In this study, two modified analytical methods such as the modified potassium permanganate method for and the modified closed reflux method using potassium dichromate for were compared. In the preliminary experiment to estimate the capability of the two oxidants for glucose oxidation, and were about 70% and 100% of theoretical oxygen demand(ThOD), respectively, indicating that was very close to the ThOD. The effective titration ranges in and were 3.2 to 7.5 mL and 1.0 to 5.0 mL for glucose, 4.3 to 7.5 mL and 1.4 to 4.3 mL for lake sediment, and 2.5 to 5.8 mL and 3.6 to 4.5 mL for river sediment, respectively, within 10% errors. For estimating recovery(%) in glucose-spiked sediment after aging for 1 day, the mass balances of the and among glucose, sediments and glucose-spiked sediments were compared. The recoveries of and were 78% and 78% in glucose-spiked river sediments, 91% and 86% in glucose-spiked lake sediments, 97% and 104% in glucose-spiked sand, and 134% and 107% in glucose-spiked clay, respectively. In conclusion, both methods have high confidence levels in terms of analytical methodology but show significant different concentrations due to difference in the oxidation powers of the oxidants.

Effects of commercial in ovo injection of carbohydrates on broiler embryogenesis ,

The effects of in ovo injection of different carbohydrate solutions on hatchability of fertilized eggs (HF), rate of hatch, BW, body moisture, yolk sac weight, and yolk sac moisture of Ross × 708 broiler chicks, hatched from eggs laid by a 34-wk-old breeder flock, were investigated. Eggs containing live embryos were injected, using an automated multiple-egg injector, in the amnion on d 18.5 of incubation with 0.1, 0.4, 0.7, or 1.0 mL of commercial diluent or a carbohydrate dissolved in diluent. The commercial diluent containing 0.25 g/mL of one of the following carbohydrates was injected into eggs: glucose, fructose, sucrose, maltose, or dextrin. The results showed that no carbohydrate type or solution volume affected rate of hatch. Absolute and proportional BW on day of hatch were positively related to injection volume (P < 0.001). However, HF was negatively related to injection volume (P < 0.001). To realize an HF of 90%, the injection volume could not exceed 0.4 mL for fructose or sucrose and could not exceed 0.7 mL for glucose, maltose, or dextrin. Yolk-free BW was negatively related to injection volume of fructose and sucrose (P < 0.004), but was not related to injection volume of diluent, glucose, maltose, and dextrin. Conversely, absolute and proportional yolk sac weights were positively related to injection volume of fructose, sucrose, and dextrin (P < 0.01), but were also not significantly related to injection volume of diluent, glucose, and maltose. Yolk sac moisture was positively related to injection volume for all injectables, including the diluent (P < 0.03). However, body moisture and yolk-free body moisture were not related to injection type or volume. In conclusion, the use of carbohydrates added to a commercial diluent for the in ovo injection of broiler hatching eggs requires the use of appropriate volumes to promote growth and nutrient utilization without adversely affecting HF.

INOCULAÇÃO DE GLICOSE EM OVOS EMBRIONADOS DE FRANGO DE CORTE: PARÂMETROS DE INCUBAÇÃO E DESEMPENHO INICIAL

Two experiments were conducted to evaluate the glucose supplementation in embryonic low weight eggs on hatching parameters and performance of broiler chicks in the initial period. In the first experiment the treatments were the following: Eggs without supplementation, inoculated with water, inoculated with 0.2 mL of glucose + 0.4 mL of water, inoculated with 0.6 mL of glucose. In the second experiment the treatments were the following: High weight eggs without supplementation, low weight eggs without supplementation, low weight eggs inoculated with 0.6 mL of saline solution, low weight eggs inoculated with 0.1 g. of glucose in 0.6 mL of NaCl (0.9%) solution, low weight eggs inoculated with 0.2 g. of glucose in 0.6 mL of NaCl (0.9%) solution. The supplementation took place on the 16th day of incubation. The experimental design was in randomized blocks with four replicates for the first experiment and six replicates for the second experiment and ten birds in each replicate. There were evaluated the moment of internal pipping, external pipping, hatching time, embryo mortality, hatching rate and chick performance until ten days of age. The data were analyzed by PROG GLM of SAS software and Tukey test (P 0.05) and the utilization of 0.6 mL of glucose decreased the hatching rate (P>0,05). The glucose supplementation in eggs did not improve the chick quality and the performance of chicks in the initial phase. KEY WORDS: Incubation, in ovo nutrition, low weight chicks, post-hatching, pre-hatching.

Entero-pancreatic neurons are responsible for the intestinal phase of pre absorptive insulin secretion

Abstract Insulin is a key hormone of the intermediary metabolism and its early secretion after a meal has a major role in the overall organism glucose sensitivity. Pre absorptive insulin secretion (PAIS) includes a cephalic phase (implicating oro-pharyngeal receptors) and an intestinal phase (implicating gastric and duodenal receptors). Entero-pancreatic (EP) neurons, which originate from the antral and the proximal duodenal intrinsic nervous systems, form varicosities in pancreatic ganglia and islets and may account for the intestinal phase of PAIS. To test this hypothesis, post prandial portal insulin and arterial glucose concentrations were compared in (i) intact pigs (IEP), (ii) pigs with gastric canula, (IEP + GC) and (iii) pigs with gastric canula and surgically interrupted EP neurons (XEP + GC) ( n = 8). EP neurons section was achieved by sectioning the connective attachments between the pancreas and the proximal duodenum and the antrum. The test meal (800 ml of glucose 5%) was ingested voluntarily (IEP), or directly introduced into the stomach (IEP + GC, XEP + GC), to discriminate between the cephalic and the intestinal phases of PAIS. PAIS was significantly decreased in IEP + GC compared to IEP (AUC = 59 ± 21.2 vs 18 ± 6.6 μUI/ml/5 min for IEP vs IEP + GC, p = 0.04). PAIS was further nullified in XEP + GC (AUC = − 2 ± 8.1 μUI/ml/5 min). Glycemia was not modified in IEP, IEP + GC or XEP + GC. We conclude that EP neurons are responsible for the intestinal phase of PAIS since it disappeared in XEP + GC.

Statistical Medium Formulation and Process Modeling by Mixture Design of Experiment for Peptide Overexpression in Recombinant Escherichia coli

The medium formulation and robust process modeling for anti-HIV peptide (T-20) production by recombinant Escherichia coli overexpression were studied by employing a crossed experimental design. The crossed design, a mixture design combined with process factor (induction duration), was used to find the optimal medium formulation and process time. The optimal settings for three major components (7.75 mL of NPK sources, 5.5 mL of glucose, and 11.75 mL of MgSO4) characterized by %T-20 (14.45%), the proportion of peptide to the total protein, were observed in a total of 100 mL of medium inducted at an optical density of 0.67 with 0.7 mM isopropyl-beta-D-thiogalactopyranoside) for a 3-h induction duration at shake-flask scale. These conditions were further investigated to find robust process conditions (8.2 mL of NPK sources, 5.6 mL of glucose, and 11.3 mL of MgSO4, and a 3.5-h induction duration time) for T-20 production (13.9%) by applying propagation of error.

Sequential and Simultaneous Statistical Optimization by Dynamic Design of Experiment for Peptide Overexpression in Recombinant Escherichia coli

The production of recombinant anti-HIV peptide, T-20, in Escherichia coli was optimized by statistical experimental designs (successive designs with multifactors) such as 2(4-1) fractional factorial, 2(3) full factorial, and 2(2) rotational central composite design in order. The effects of media compositions (glucose, NPK sources, MgSO4, and trace elements), induction level, induction timing (optical density at induction process), and induction duration (culture time after induction) on T-20 production were studied by using a statistical response surface method. A series of iterative experimental designs was employed to determine optimal fermentation conditions (media and process factors). Optimal ranges characterized by %T-20 (proportion of peptide to the total cell protein) were observed, narrowed down, and further investigated to determine the optimal combination of culture conditions, which was as follows: 9, 6, 10, and 1 mL of glucose, NPK sources, MgSO4, and trace elements, respectively, in a total of 100 mL of medium inducted at an OD of 0.55-0.75 with 0.7 mM isopropyl-beta-D-thiogalactopyranoside in an induction duration of 4 h. Under these conditions, up to 14% of T-20 was obtained. This statistical optimization allowed the production of T-20 to be increased more than twofold (from 6 to 14%) within a shorter induction duration (from 6 to 4 h) at the shake-flask scale.

Comparison of hyperbaric and plain ropivacaine 15 mg in spinal anaesthesia for lower limb surgery

Previously, plain ropivacaine 15 mg given intrathecally has been shown to be feasible for ambulatory surgery of lower-extremities. Hypothetically, hyperbaric solution could improve and shorten the block. This prospective, randomized, double-blind study included 56 patients undergoing surgery of lower extremities. They received intrathecally either 1.5 ml of ropivacaine 10 mg ml(-1) and 0.5 ml of glucose 300 mg ml(-1) (HYP) or 2 ml of ropivacaine 7.5 mg ml(-1) (PL). All patients in Group HYP achieved T(10) dermatome analgesia but only 64% (18/28) of Group PL. T(10) analgesia was reached in 5 min (median, range 5-20 min) in the HYP group vs 10 min (5-45 min) in the PL group (P=0.022), and full motor block in 10 min (5-45 min) vs 20 min (5-60 min) (P=0.003), respectively. Group HYP had a longer duration of analgesia at T(10); 83 min (5-145 min) vs 33 min (0-140 min) (P=0.004). Duration of sensory block from injection of the anesthetic to complete recovery was shorter in Group HYP than in Group PL, 210 min (120-270 min) vs 270 min (210-360 min) (P<0.001), as was duration of motor block, 120 min (5-150 min) vs 210 min (120-330 min) (P<0.001). Patients of Group HYP attained discharge criteria earlier than those of Group PL (P=0.009). In comparison with the plain solution, 15 mg of intrathecal hyperbaric ropivacaine produced a faster onset, greater success rate of analgesia at the level of T(10) dermatome, and faster recovery of the block.

EMLA ® cream and oral glucose for immunization pain in 3-month-old infants

The objective of this study is to determine whether use of lidocaine–prilocaine 5% cream (EMLA ®) and oral glucose decreases pain associated with diphteria–pertussis–tetanus (DPT) immunization in 3-month-old infants. Design: randomized, double-blind, controlled trial in outpatient paediatric practice in northern Sweden. EMLA or placebo was applied to the infant’s lateral region of the right thigh and covered with an occlusive dressing 1 h before the immunization. In addition, 1 ml of glucose (300 mg/ml) or placebo (water) was instilled on the baby’s tongue within 2 min before the DPT-injection. Forty-five infants received EMLA and glucose and 45 infants placebo cream and water. ECG was recorded and stored in a computer and the procedure was videotaped. The parents and the nurse assessed the infants' pain on a visual analogue scale (VAS) after the immunization. Heart rate and heart rate variability pre- and post-injection were calculated. From the videotapes, the modified behavioural pain scale (MBPS) was used to assess pain scores during baseline and after immunization. The latency of the first cry and total crying time were measured. The parents and the nurse scored the infants' pain on the VAS significantly lower in the treatment group than in the placebo group. The infants' responses to the immunization measured as the difference in MBPS scores pre- and post-injection were significantly lower in the EMLA–glucose group compared with the placebo group. More infants cried after the immunization in the placebo group compared with the EMLA–glucose group and the latency of the first cry after the injection was shorter in the placebo group. A biphasic transient heart rate response with a marked deceleration followed by a subsequent acceleration was seen more frequently in the placebo group compared to the EMLA–glucose group. EMLA and glucose alleviate immunization pain in 3-month-old infants.

Simple partial least squares–attenuated total reflectance Fourier transform infrared spectrometric method for the determination of sugars in fruit juices and soft drinks using aqueous standards

A simple analytical procedure was developed for the direct determination of sugars in fruit juices (apple, orange, grape) and soft drinks. The method is based on the partial least squares treatment of attenuated total reflectance Fourier transform infrared spectrometric data obtained in the wavenumber range 4000–700 cm–1 and does not require any sample pre-treatment. Absorbance and first-derivative spectra were employed for measurements, using a reduced set of eight aqueous standard mixtures of glucose, fructose and sucrose at two concentration levels for calibration. The limits of detection found for absorbance measurements were 0.2 g per 100 ml for total sugar and 0.1, 0.1 and 0.03 g per 100 ml for glucose, fructose and sucrose, respectively. Relative standard deviations varied from 1.7 to 2.0% for six independent measurements of individual and total sugar concentration. In the analysis of real and synthetic samples, precise and accurate results were obtained, providing accuracy errors lower than 2% in all cases. Average recoveries of 96 ± 4% for total sugar and between 93 ± 7 and 99 ± 7% for single sugars demonstrate the applicability of the methodology developed to the direct analysis of fruit juice and soft drink samples.

PLS-NIR determination of total sugar, glucose, fructose and sucrose in aqueous solutions of fruit juices

An analytical procedure has been developed for the direct determination of sugars in fruit juice samples. The method is based on the partial least-squares (PLS) treatment of first derivative near infrared (NIR) spectroscopic data obtained between 1200 and 2450 nm, using 1 mm pathlength cell and a multicomponent calibration set, including seven binary mixtures and 10 ternary mixtures of glucose, fructose and sucrose. The limit of detection values found are of the order of 0.2 g/100 ml for total sugar and 0.2, 0.4 and 0.5 g/100 ml for glucose, fructose and sucrose, respectively. Relative standard deviation values obtained vary from 0.4% to 2.3% for six independent measurements of individual sugar concentrations from 15.4 to 2.4 g/100 ml and 0.03% for total sugar of the order of 20 g/100 ml. Average recovery percentages of 99 ± 2 for total sugar and between 98 ± 4 and 100 ± 4 for single sugar determinations evidence the applicability of the methodology developed for the analysis of juice samples.

Postprandial Responses of Liver Blood Flow Prior to and Following Hepatectomy in Conscious Dogs

The responses of the portal and hepatic arterial blood flows to various diets and nutrients were measured simultaneously in conscious dogs prior to and following hepatic resection. Prior to hepatectomy, the increase in the portal blood flow was significantly larger in response to an elemental diet, fats, or amino acids than to glucose or water. The peak increase was 60.2 ± 14.4 ml for water, 144.7 ± 22.1 ml for a 150-cal elemental diet, 168.5 ± 16.1 ml for a 300-cal elemental diet, 86.7 ± 14.0 ml for a glucose solution, 159.3 ± 16.7 ml for an amino acid meal, and 188.5 ± 25.3 ml for a fat meal. Following partial hepatectomy, fats and amino acids induced an increase in the portal blood flow similar to that prior to hepatectomy. Glucose and the elemental diet, on the other hand, induced a significantly larger increase in portal blood flow following the surgery although water did not. The peak increase was 144.4 ± 27.8 ml for glucose (166% of the peak increase prior to hepatectomy) and 221.8 ± 32.5 ml for the 300-cal elemental diet (132%). The postprandial response of the hepatic artery to every diet was quite different among the dogs and there were no significant changes both prior to and following surgery. The different response of the portal flow to intraluminal glucose following partial hepatectomy may be due to alterations in glucose metabolism following hepatectomy. We have shown that the postprandial response of the portal blood flow varies with the type of nutrient, and it can be altered by hepatectomy.
