The aim of this study was to determine the physicochemical parameters, i.e. water, protein, fat, ash, sodium and carbohydrate content and energy value, as well as fatty acid composition and pH of snail meat from two species, Cornu aspersum maximum and Cornu aspersum Müller. The snail meat was found to have relatively high protein content (13.12 g/100 g vs. 16.53 g/100 g), low fat content (0.89 g/100 g vs. 1.21 g/100 g), and low energy value (343.8 kJ vs. 379.2 kJ). The pH of snail meat was very high (8.59 vs. 8.19). On average, snail meat has a favourable fatty acid composition as it contains 27.08 wt. % saturated (SFA), 19.00 wt. % monounsaturated, and 53.92 wt. % polyunsaturated fatty acids (PUFA). It has a favourable PUFA/SFA ratio (1.99), but an unfavourable n-6/n-3 ratio (20.33) and a relatively high proportion of trans fatty acids (3.93 wt. %). The fatty acid profile of snail meat is dominated by linoleic acid (20.89 wt. %), arachidonic acid (13.27 wt. %), oleic acid (12.67 wt. %), nonadecanoic acid (10.23 wt. %), and stearic acid (10.08 wt.%). The aim of our study was also to verify the culinary value of snail meat. For this purpose, two snail meat pâtés of acceptable sensory quality were prepared. The panel evaluated the sensory quality of the pâté made from the meat (foot and liver) of the snail Cornu aspersum Müller significantly worse than the pâté made from the meat of the snail Cornu aspersum maximum, mainly due to the unpleasant aroma, in which the soapy, sweet and spicy components predominated, as well as the absence of the snail meat aroma.

Texto completo da fonteResumo:
Background Physical activity is beneficial for cardiovascular rehabilitation. Digitalization suggests using technology in the promotion of physical activity and lifestyle changes. The effectiveness of distance technology interventions has previously been found to be similar to that of conventional treatment, but the added value of the technology has not been frequently studied. Objective The aim of this pilot study was to investigate whether additional distance technology intervention is more effective in promoting physical activity than non-technology–based treatment in 12 months of cardiac rehabilitation. Methods The cardiovascular disease rehabilitation intervention consisted of three 5-day inpatient periods in a rehabilitation center and two 6-month self-exercise periods at home in between. Participants were recruited from among cardiac patients who attended the rehabilitation program and were cluster-randomized into unblinded groups: conventional rehabilitation control clusters (n=3) and similar rehabilitation with additional distance technology experimental group clusters (n=3). Experimental groups used Fitbit Charge HR for self-monitoring, and they set goals and reported their activity using Movendos mCoach, through which they received monthly automated and in-person feedback. Physical activity outcomes for all participants were measured using the Fitbit Zip accelerometer and the International Physical Activity Questionnaire. Results During the first 6 months, the experimental group (n=29) engaged in light physical activity more often than the control group (n=30; mean difference [MD] 324.2 minutes per week, 95% CI 77.4 to 571.0; P=.01). There were no group differences in the duration of moderate to vigorous physical activity (MD 12.6 minutes per week, 95% CI –90.5 to 115.7; P=.82) or steps per day (MD 1084.0, 95% CI –585.0 to 2752.9; P=.20). During the following 6 months, no differences between the groups were observed in light physical activity (MD –87.9 minutes per week, 95% CI –379.2 to 203.3; P=.54), moderate to vigorous physical activity (MD 70.9 minutes per week, 95% CI –75.7 to 217.6; P=.33), or steps per day (MD 867.1, 95% CI –2099.6 to 3833.9; P=.55). Conclusions The use of additional distance technology increased the duration of light physical activity at the beginning of cardiac rehabilitation (for the first 6 months), but statistically significant differences were not observed between the two groups for moderate or vigorous physical activity or steps per day for both 6-month self-exercise periods.

The X-ray single-crystal structure of (2S,5R,6R)-6-amino-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid, commonly known as (+)-6-aminopenicillanic acid (C8H12N2O3S) and a precursor of a variety of semi-synthetic penicillins, has been determined from synchrotron data at 150 K. The structure represents an ordered zwitterion and the crystals are nonmerohedrally twinned. The crystal structure is composed of a three-dimensional network built by three charge-assisted hydrogen bonds between the ammonium and carboxylate groups. The complementary analysis of the crystal packing by thePIXELmethod brings to light the nature and ranking of the energetically most stabilizing intermolecular interaction energies. In accordance with the zwitterionic nature of the structure,PIXELlattice energy calculations confirm the predominance of the Coulombic term (−379.1 kJ mol−1) ahead of the polarization (−141.4 kJ mol−1), dispersion (−133.7 kJ mol−1) and repulsion (266.3 kJ mol−1) contributions.

Texto completo da fonteResumo:
(1) Background: The King-Devick (KD) rapid number naming test is sensitive for concussion diagnosis, with increased test time from baseline as the outcome measure. Eye tracking during KD performance in concussed individuals shows an association between inter-saccadic interval (ISI) (the time between saccades) prolongation and prolonged testing time. This pilot study retrospectively assesses the relation between ISI prolongation during KD testing and cognitive performance in persistently-symptomatic individuals post-concussion. (2) Results: Fourteen participants (median age 34 years; 6 women) with prior neuropsychological assessment and KD testing with eye tracking were included. KD test times (72.6 ± 20.7 s) and median ISI (379.1 ± 199.1 msec) were prolonged compared to published normative values. Greater ISI prolongation was associated with lower scores for processing speed (WAIS-IV Coding, r = 0.72, p = 0.0017), attention/working memory (Trails Making A, r = −0.65, p = 0.006) (Digit Span Forward, r = 0.57, p = −0.017) (Digit Span Backward, r= −0.55, p = 0.021) (Digit Span Total, r = −0.74, p = 0.001), and executive function (Stroop Color Word Interference, r = −0.8, p = 0.0003). (3) Conclusions: This pilot study provides preliminary evidence suggesting that cognitive dysfunction may be associated with prolonged ISI and KD test times in concussion.

Abstract OBJECTIVE To describe clinical findings, treatments, and outcomes for cattle with complete traumatic exungulation. ANIMALS 10 bovines. PROCEDURES Record databases of 2 teaching hospitals were searched to identify cattle treated for traumatic exungulation between January 1993 and December 2018. Information about signalment, clinical signs and findings, treatment, and outcome was extracted from the records or obtained by telephone communication with the owner. RESULTS Records for 5 bulls, 4 heifers, and 1 cow with a median age of 2 years (range, 1 day to 10 years) and weight of 379.1 kg (range, 30 to 909.1 kg) were reviewed. Duration of clinical signs ranged from ≤ 24 hours to 3.5 days. Five of 7 animals had a lameness score > 3/5. Complete exungulation occurred in 6 medial digits (3 hind limbs and 3 forelimbs) and 5 lateral digits (1 hind limb and 4 forelimbs); 1 calf had complete exungulation of both digits of a forelimb. Treatments included bandaging (n = 9), antimicrobials (9), anti-inflammatories (8), hoof block application to the adjacent digit (7), regional anesthesia (6), cast application (4), curettage of the third phalanx (3), regional antimicrobial perfusion (1), and local application of antimicrobial-impregnated beads (1). All 7 cattle with long-term (≥ 9 months) information available returned to their intended function; 6 had no residual lameness, and 3 required regular corrective trimming of the affected digit. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested the prognosis for long-term survival and return to intended function is fair to good for cattle with complete exungulation.

Hot water was used to obtain Chlorella sorokiniana hot water extract (HWE). Subsequently, this byproduct was freeze-dried, hydrolysed at 50 °C using Protease N to obtain C. sorokiniana protein hydrolysates (PN-1), and then digested with a gastrointestinal enzyme (PN-1G). The inhibitory effects of the HWE and hydrolysates against angiotensin I-converting enzyme (ACE) were investigated. The soluble protein and peptide contents were 379.9 and 179.7 mg/g, respectively, for HWE and 574.8 and 332.8 mg/g, respectively, for PN-1. The IC50 values of the HWE, PN-1, and PN-1G on ACE were 1.070, 0.035, and 0.044 mg/mL, respectively. PN-1G was separated into seven fractions through size exclusion chromatography. The sixth fraction of the hydrolysate had a molecular weight between 270 and 340 Da, and the lowest IC50 value on ACE was 0.015 mg/mL. The amino acid sequences of the ACE-inhibitory peptides were Trp-Val, Val-Trp, Ile-Trp, and Leu-Trp, of which the IC50 values were 307.61, 0.58, 0.50, and 1.11 µΜ, respectively. Systolic blood pressure and diastolic blood pressure were reduced 20 and 21 mm Hg, respectively, in spontaneously hypertensive rats after 6 h of oral administration with a dose of 171.4 mg PN-1 powder/kg body weight.

In this research, we want to experiment to find out the compressive strength of medium quality concrete K-350 with ingredients added MASTER RHEOBUILD 6, whose function is to accelerate hardening, improve the quality of concrete, reduce water use and increase the value of slump. However, it should be noted that errors in dosages and how to use added ingredients can be detrimental to the quality of concrete. The results of the study show that the addition of 0.25, 0.5 and 0.75 liters per 50 kg of cement can increase the concrete compressive strength. The compressive strength of concrete with the addition of 0.25 liters/50 kg of cement has increased 362.67 kg/cm� from the normal concrete compressive strength of 350.58 kg/cm2. The addition of 0.5 liters/50 kg of cement has increased again to 373.24 kg/cm�, and the addition of 0.75 liters/50 kg of cement has increased the concrete compressive strength to 379.29 kg/cm� of normal concrete. Comparison of compressive strength before and after addition of admixture with an increase of 3.45% in addition of 0.25 liters/50 kg of cement, 6.47% in addition of 0.5 liters/50 kg of cement and 8.19% in addition of 0.75 liters/50 kg of cement.

This paper focused on evaluating the effect of aggregate gradation and polymer modification on indirect tensile strength (ITS) and the static stiffness for hot asphalt mixtures. In particular, data from ITS tests have been processed to obtain stiffness measurements through the application of Hondros theory. The results showed that fine mixtures had a better tensile strength by 26.3% than the coarse mixtures. The effect of compaction also was examined, the results showed that samples compacted with the Superpave gyratory compactor (SGC) had an enhancement in ITS by 36.58 and 23.1% in comparison with Marshall and roller compactor respectively. Polymer modifiers were used to estimate their effect on tensile strength, adding 4, 6, and 8% of Styrene-Butadiene-Styrene (SBS), which can rise the ITS by 3.2,6.14 and 13.3% of the non-modified asphalt mixture. Furthermore, using 4, 6, and 8 percent of SBS could increase static stiffness by 53.9, 209.6, and 302.4% respectively for roller compacted fine mixes and 58, 220, and 379.3% for SGC compacted mixes. Furthermore, SBS raised the stiffness modulus by 52.3, 188, and 295% for Marshall compacted mixes. Using hybrid modifier can improve the stiffness of the asphalt mixture. However, The results indicate that using 1, 2 and 3% polyvinyl chloride (PVC) can magnify the stiffness of mixtures by 41.2, 199.8% and 262.6 for roller compacted mixtures and 133.4, 212.1 and 354% for SGC compacted mixtures, whereas there is a stringent increasing by 133.4, 189.2 and 354% for Marshall compacted mixes. Otherwise, polymer-modification can decrease the fracturing index for coarse and fine mixtures.

Cytomegalovirus (CMV) infection is the most severe viral infection in renal transplant recipients, which can occur in the post-transplant period in both adult and pediatric recipients. Developing and applying an effective prevention and treatment strategy for pediatric renal graft recipients is a priority. Objective: to compare the effectiveness of the protocols used for the prevention of CMV infection in pediatric kidney transplant recipients.Materials and methods. The study enrolled 118 patients who underwent primary kidney transplantation at Shumakov National Medical Research Center of Transplantology and Artificial Organs. Based on retrospective analysis, all recipients were divided into two groups, depending on the prophylactic strategy after kidney transplantation. The followup period for pediatric kidney recipients ranged from 108 to 1803 (623.5 ± 379.5) days. CMV infection activity was monitored by polymerase chain reaction.Results. The frequency of CMV infection activation episodes at 3 and 6 months was independent of the prophylaxis strategy used. The recurrence rate of CMV infection one year after surgery was significantly lower (p = 0.037) with Strategy 2. No cases of CMV syndrome or CMV disease, graft dysfunction, or chronic rejection associated with CMV infection were reported. Increasing the dose of antiviral drugs in Strategy 1 did not increase the risk of cytotoxicity and nephrotoxicity, which are reversible (creatinine levels were not significantly different in the study groups at 3, 6, 12 months, p = 0.542, p = 0.287, p = 0.535, respectively). The incidence of kidney graft rejection did not increase in patients with lower doses of immunosuppressants in Strategy 2.Conclusion. Both prophylactic strategies are effective in pediatric kidney recipients. However, the choice of a strategy depends on the individual characteristics of the patient and requires a personalized approach.

Herein, we present a qualitative and quantitative analysis of the compositions of plasmalogens and phospholipids (PLs) in dried big head shrimp (Solenocera melantho), opossum shrimp (Neomysis awatschensis), mussel (Mytilus galloprovincialis), and sea cucumber (Apostichopus japonicus). We also analyze the fatty acid composition of the extracted lipids, phosphatidyl choline (PtdCho), and plasmalogen choline (PlsCho) from each sample. In big head shrimp, opossum shrimp, and mussel, phosphatidyl choline (PtdCho) was the most abundant PL at 1677.9, 1603, and 1661.6 mg/100 g of dried sample, respectively, whereas the most abundant PL in sea cucumber was PlsCho (206.9 mg/100 g of dried sample). In all four samples, plasmalogen ethanolamine (PlsEtn) was higher than phosphatidyl ethanolamine (PtdEtn). The content (mg/100 g of dried sample) of PlsCho was highest in mussel (379.0), and it was higher in big head shrimp (262.3) and opossum shrimp (245.6) than sea cucumber (206.9). The contents (mg/100 g of dried sample) of PlsEtn were in the order of mussel (675.4) > big head shrimp (629.5) > opossum shrimp (217.9) > sea cucumber (51.5). For analyzing the fatty acids at the sn-2 position of PlsCho, the consecutive treatment with phospholipase A1, solid phase extraction, thin-layer chromatography (TLC), and GC-FID were applied. The most abundant fatty acid was eicosapentaenoic acid (EPA, C20:5, n-3) in big head shrimp and sea cucumber, palmitoleic acid (C16:1, n-7) in opossum shrimp, and docosadienoic acid (C22:2, n-6) in mussel.
