The effects of pre-plant dips and post-plant treatments on the infection by Colletotrichum acutatum, survival, and yields of strawberry plants were evaluated over two seasons in Florida using naturally infected transplants imported from northern nurseries. Handling practices such as washing, refrigerating, and dipping plants in water had no effect on infection, survival, or yield. Pre-plant dips with the fungicide Switch 62.5 WDG (cyprodinil + fludioxonil) and, in some cases, with Abound 2.08F (azoxystrobin), reduced infection and plant mortality, and increased yield. Pre-plant dips with Oxidate (hydrogen peroxide) were ineffective and, in some cases, increased plant mortality and reduced yield. Fertilizer treatments, such as dipping and spraying plants with Brotomax (8-0-0 plus micronutrients) or application of slow-release Osmocote (15-9-12 plus micronutrients) after planting, had no effect or reduced plant survival and yield. Post-plant application of Surround WP, a kaolin clay intended to reduce heat stress and control mites and insects, had little or no effect on infection, survival, or yield. In summary, strawberry transplants infected with C. acutatum can be dipped in Switch or Abound at planting to reduce infection and increase survival and yield, but other treatments and practices examined are unlikely to have beneficial effects.

Main Effects

This study puts particular emphasis on the role of copper ions in the performance of hydrogen peroxide bleaching (P-stage). Owing to their variable levels across the bleaching line due to washing filtrates, bleaching reagents, and equipment corrosion, these ions can play a major role in hydrogen peroxide decomposition and be detrimental to polysaccharide integrity. In this study, a Cu-contaminated D0(EOP)D1 prebleached pulp was subjected to an acidic washing (A-stage) or chelation (Q-stage) before the alkaline P-stage. The objective was to understand the isolated and combined role of copper ions in peroxide bleaching performance. By applying an experimental design, it was possible to identify the main effects of the pretreatment variables on the extent of metals removal and performance of the P-stage. The acid treatment was unsuccessful in terms of complete copper removal, magnesium preservation, and control of hydrogen peroxide consumption in the following P-stage. Increasing reaction temperature and time of the acidic A-stage improved the brightness stability of the D0(EOP)D1AP bleached pulp. The optimum conditions for chelation pretreatment to maximize the brightness gains obtained in the subsequent P-stage with the lowest peroxide consumption were 0.4% diethylenetriaminepentaacetic acid (DTPA), 80ºC, and 4.5 pH.

The possibilities of pathogens transmitting zoonotic diseases to fish or aquatic environments are dependent on seasons, patients’ contact with fish or fish related environment, nutritional habits and the immune system level of the exposed individual. Consumption of aquatic food is on the increase, and thus explains the answers to the increase in zoonotic contraction cases found in man. Zoonotic infections can be classified into infections caused by: a) direct interaction with infected animals b) consumption of raw or undercooked aquatic products. Pathogens may be natives of the said aquatic environment or may occur as a result of environmental pollution such as the use of fertilizer, human waste or any of the anthropogenic substances. Zoonotic infections can be passed to man through fish via any of the following hosts: Helminths, Bacteria, Protozoa and Arthropods.Nevertheless, once the chemistry and control of zoonoses is understood, putting up measure to adequately address them when necessary will not be challenging. More so, educating the public on the need for prevention, proper cooking of aquatic products, and also a constant reminder of potential dangers are necessary to reinforce proper sea food handling practices.

The effect of intratendineous injections of polysulphated glycosaminoglycan (PSGAG) as treatment of collagenase-induced tendonitis was studied. Two groups (GI and GII) of five Arabian horses each, males and females, two to six year-old, were submitted to experimental tendinitis of the superficial digital flexor tendon of the left thoracic limb by intratendineous injection of 1.0ml of collagenase (2.5mg/ml). Seven days after the induced-lesions were created, the horses of GI received five intralesional injections of 1.0ml (125mg) of PSGAG, every four days. Horses of GII received injections of saline in the same dose and rate. Clinical and ultrasonographic evaluations were performed periodically, during 150 days. All animals showed lameness, increased local pain, heat and swelling 24 hours after the injury was created. All signs, except to swelling, which remained visible by the end of the study, showed regression in all animals. Lesions of variable size, shape and position were evidenced by the ultrasonographic evaluation, reaching maximum severity between the seventh and the 23rd days. By the end of the study, the echogenicity grade ranged from 1 to 2, and the grade of fiber alignment from 0 to 2. The histopathologic analysis demonstrated repair areas with intense fibroplasia and neovascularization, collagen fibers poorly organized, and thickened hypercellular endotenon. The data of this study did not show significant differences between the treated and control groups, therefore leading to the conclusion that the intralesional injection of PSGAG did not have beneficial effects in the treatment of collagenase-induced tendinitis.

The mainstay of phenylketonuria treatment is a low protein diet, supplemented with phenylalanine (Phe)-free protein substitutes and micronutrients. Adhering to this diet is challenging, and even patients with good metabolic control who follow the dietary prescriptions in everyday life ignore the recommendations occasionally. The present study explores the ability of slow-release large neutral amino acids (srLNAAs) to prevent Phe increase following a Phe dietary load. Fourteen phenylketonuric patients aged ≥13 years were enrolled in a 6-week protocol. Oral acute Phe loads of 250 and 500 mg were added to the evening meal together with srLNAAs (0.5 gr/kg). Phe and tyrosine were dosed before dinner, 2h-after dinner, and after the overnight fast. After oral Phe loads, mean plasma Phe remained stable and below 600 µmol/L. No Phe peaks were registered. Tyrosine levels significantly increased, and Phe/Tyrosine ratio decreased. No adverse events were registered. In conclusion, a single oral administration of srLNAAs at the dose of 0.5 gr/kg is effective in maintaining stable plasma Phe during acute oral loads with Phe-containing food and may be added to the dietetic scheme in situations in which patients with generally good adherence to diet foresee a higher than prescribed Phe intake due to their commitments.

Introduction: Immunomodulator glutamine and probiotic Lactobacillus at certain doses have beneficial effects by modulation of the immune system and may assist in the integrity of therespiratory system. However, studies about the effects of glutamine or Lactobacillus pool on the prevention and control of asthma in children are still scarce. The aim of study was to evaluate the effect of the use of glutamine and Lactobacillus pool on the attenuation of clinical asthma symptoms in children. Methods: Longitudinal study, 45 children with medical diagnosis of asthma distributed in three groups: control group (C), glutamine group (G), Lactobacillus group (L). Group G was supplemented with L-glutamine powder (0.3 g/kg/day). Group L used a pool of Lactoba- cillus (Lactobacillus casei, paracasei, rhamnosus, acidophilus and Bifidobacterium lactis) (2 g/day). Group C received no glutamine or Lactobacillus pool. Clinical characteristics and symptoms of respiratory diseases were assessed by study-specific anamnesis and ISSAC Questionnaire (to obtain diagnostic scores and asthma symptoms) for 4 months. To test for differences between groups, the ANOVA test with Tukey post-hoc test was used. It was considered significant p <0.05. Results: Initial ISSAC score was (C=8.67±1.77, L=7.80±1.52 and G=8.00 ± 1.46, p=0.31). At the first follow-up, the ISSAC score indicated that group G had improvement in the clinical characteristics of asthma (C=6.47±2.29, L = 5.07±2.28, G = 4.00±1.73, p <0.05), as also occurred in the following months until the last follow-up (C=5.93±2.28, L=5.13±2.13, G=4.00±1.96, p<0.05). After supplementation, group G presented lower mean duration of asthma attack (p=0.01), lower number of asthma attack (p<0.05), lower prevalence of typical asthma symptoms, as cough and wheezing (p<0.05). Conclusion: Glutamine supplementation attenuated the typical asthma symptoms, while the use of Lactobacillus pool did not attenuate the symptoms. Glutamine may be a new strategy for prevention and control of asthma in children.

The purpose of this study was to investigate the effect of acute high intensity aerobic training on ANP and Endothelin-1 in inactive obese women. In order to nineteen obese women mean age± SD: 27.94± 3.30, mean weight ±SD: 88.13 ±7.28, mean height ±SD: 163.00± 4.91, mean BMI ±SD: 32.96± 3.13 selected and were randomly allocated to experimental and control groups. Experimental group performed a session acute aerobic exercise on ergometer at intensity 25w that increased every two minute 25w to workload and performed to exhaustion every subject. Samples blood were taken after 12 hours fasting, before and after of program training. For analyzed of biochemical variables used ELISA method and for analyses data used ANOVA. Results of this study showed that acute aerobic training causes significant increase in level of plasma ANP in obese women (p=0.006). But no significant differences observe in plasma level of Endothelin-1. Also, any significant difference didn’t observe between pre and post-training values, were separately compared data in each group. Finally, according to results of this study, acute aerobic training causes of the direct relationship between obesity and hypertension and cardiovascular disease probably beneficial effects of physical activity in obese people is due to change in these indicators.

Stem cell-based therapies rely on stem cell ability to repair in an oxidative stress environment. Preconditioning of mesenchymal stem cells (MSCs) to a stress environment has beneficial effects on their ability to repair injured tissues. We previously reported that MSCs from thedecidua basalis(DBMSCs) of human placenta have many important cellular functions that make them potentially useful for cell-based therapies. Here, we studied the effect of DBMSC preconditioning to a stress environment. DBMSCs were exposed to various concentrations of hydrogen peroxide (H2O2), and their functions were then assessed. DBMSC expression of immune molecules after preconditioning was also determined. DBMSC preconditioning with H2O2enhanced their proliferation, colonogenicity, adhesion, and migration. In addition, DBMSCs regardless of H2O2treatment displayed antiangiogenic activity. H2O2preconditioning also increased DBMSC expression of genes that promote cellular functions and decreased the expression of genes, which have opposite effect on their functions. Preconditioning also reduced DBMSC expression of IL-1β, but had no effects on the expression of other immune molecules that promote proliferation, adhesion, and migration. These data show that DBMSCs resist a toxic environment, which adds to their potential as a candidate stem cell type for treating various diseases in hostile environments.

The present study was initiated to investigate the effect of oral potassium (600 mg, slow release, 24 h preslaughter), intramuscular (IM) magnesium (500 mg MgSO4, 2 h preslaughter) or slow release magnesium (Magnesium-aspartate-hydrochloride (Mg Asp) 20 or 40 (g d−1 for 5 d) on animal physiology and pork quality. Experiments were undertaken on 318 barrows and gilts (100 kg ± 5 kg) represented by three genotypes segregating at the halothane locus (nn, Nn and NN genotypes). Experiment 1 indicated that the oral potassium effectively (P ≤ 0.05) reduced pCO2 values in the nn genotype. Intramuscular injectable magnesium treatments were also found to raise plasma magnesium (P < 0.05) but did not alter muscle, liver or heart tissue levels. Both oral potassium and i.m. magnesium exacerbated subjective pork structure and texture scores but were found to increase muscle brightness and hue (higher b* value). In exp. 2, oral magnesium-aspartate (Mg Asp) was found to raise plasma, but not tissue, levels of magnesium. When fed to a group of halothane carrier pigs (Nn genotype), Mg Asp reduced muscle temperature 45 min post-stunning, increased muscle redness (CIE a* value) and reduced muscle drip loss (P < 0.06). It was concluded that oral potassium and i.m. magnesium as administered in the present study had no beneficial effects on pork quality but that the beneficial effects of Mg Asp on meat colour and drip loss may warrant further investigation.

The positive impact of probiotic strains on human health has become more evident than ever before. Often delivered through food, dietary products, supplements, and drugs, different legislations for safety and efficacy issues have been prepared. Furthermore, regulatory agencies have addressed various approaches toward these products, whether they authorize claims mentioning a disease’s diagnosis, prevention, or treatment. Due to the diversity of bacteria and yeast strains, strict approaches have been designed to assess for side effects and post-market surveillance. One of the most essential delivery systems of probiotics is within food, due to the great beneficial health effects of this system compared to pharmaceutical products and also due to the increasing importance of food and nutrition. Modern lifestyle or various diseases lead to an imbalance of the intestinal flora. Nonetheless, as the amount of probiotic use needs accurate calculations, different factors should also be taken into consideration. One of the novelties of this review is the presentation of the beneficial effects of the administration of probiotics as a potential adjuvant therapy in COVID-19. Thus, this paper provides an integrative overview of different aspects of probiotics, from human health care applications to safety, quality, and control.
