#1
Brett Richard Gardner, Emily P Mitchell
Twenty-nine wild Cape sugarbirds ( Promerops cafer) died acutely after ingestion of a homemade xylitol nectar solution from a bird feeder. The most aggressive feeders were first affected. Most birds showed clinical signs within 15 minutes of nectar ingestion, including incoordination, weakness, falling from perches, collapse, and death. A few birds showing clinical signs seemed to spontaneously recover and fly away. Full necropsy examinations done on 27 birds were hampered by freezing artifact and autolysis, but results indicated death was caused by the consequences of acute hypoglycemia...

Recent years have seen an increase in the use of lignocellulosic materials in the development of bioproducts. Because sisal fiber is a low cost raw material and is readily available, this work aimed to evaluate its hemicellulose fraction for the simultaneous production of xylitol and ethanol. The sisal fiber presented a higher hemicellulose content than other frequently-employed biomasses, such as sugarcane bagasse. A pretreatment with dilute acid and low temperatures was conducted in order to obtain the hemicellulose fraction...

Arabitol is a polyalcohol which has about 70% of the sweetness of sucrose and an energy density of 0.2 kcal/g. Similarly to xylitol, it can be used in the food and pharmaceutical industries as a natural sweetener, a texturing agent, a dental caries reducer, and a humectant. Biotechnological production of arabitol from sugars represents an interesting alternative to chemical production. The yeast Scheffersomyces shehatae strain 20BM-3 isolated from rotten wood was screened for its ability to produce arabitol from L-arabinose, glucose, and xylose...

Background: Consumer expenditures on their family pets are rapidly increasing, part of which can be attributed to prescription and OTC medications. In turn, community pharmacies are seeking and receiving an increased number of prescriptions for animals. Community pharmacists' ability to safely care for animal patients is relatively unexplored. Human medications, their normal dosing and even medication excipients could be lethal in some animal patients. Objective: The overarching objective of this study was to assess pharmacists' baseline knowledge of potential pet poisons...

Echogenic liposomes (ELIPs) are an excellent candidate for ultrasound activated therapeutics and imaging. Although multiple experiments have established their echogenicity, the underlying mechanism has remained unknown. However, freeze-drying in the presence of mannitol during ELIP preparation has proved critical to ensuring echogenicity. Here, the role of this key component in the preparation protocol was investigated by measuring scattering from freshly prepared freeze-dried aqueous solution of mannitol-and a number of other excipients commonly used in lyophilization-directly dispersed in water without any lipids in the experiment...

Bacterial biofilm which adheres onto wound surface is shown to be impervious to antibiotics and this in turn delays wound healing. Previous studies showed that antibiofilm agents such as xylitol and ethylenediaminetetraacetic acid (EDTA) prevent bacterial adherence onto surfaces. Formulation of a wound dressing containing antibiofilm agents may be a plausible strategy in breaking the biofilm on wound surfaces and at the same time increase the efficacy of the antibiotic. The purpose of this study was to develop hydrogel formulations containing antibiofilm agents along with antibiotic (gentamicin) for bacterial biofilm-associated wound infection...

The present study demonstrates utilization of secondary agricultural wastes for xylitol production. The highest xylan-to-xylose (70%) conversion was achieved using dilute nitric acid as catalyst followed by resin treatment. Results show that resin treatment efficiently removed nitrate salt (70%), phenolic content and 5-HMF (70%). Highest xylitol yield (85%) was achieved during fermentation using Candida tropicalis MTCC 6192 from the neutralized hemicellulosic hydrolysate medium. Good recovery (>15%) was achieved from corncob with 85% xylose to xylitol conversion during fermentation...

Heritiera fomes Buch.-Ham., a mangrove plant from the Sundarbans, has adapted to a unique habitat, muddy saline water, anaerobic soil, brackish tidal activities, and high microbial competition. Endophytic fungal association protects this plant from adverse environmental conditions. This plant is used in Bangladeshi folk medicine, but it has not been extensively studied phytochemically, and there is hardly any report on investigation on endophytic fungi growing on this plant. In this study, endophytic fungi were isolated from the surface sterilized cladodes and leaves of H...

The present study was aimed to investigate the health of vegetative and reproductive parts of sesame plants during Bacillus methylotrophicus KE2 interaction by their pigments, sugars, organic acid, amino acids, hormones and antioxidant production analysis. In a green-house study, B. methylotrophicus KE2 was sprayed to sesame plants at late flowering stage. The bacterial treatment enhanced photosynthetic pigments of plants including pods than their controls. The shoots of plants had higher amount of sucrose, glucose, galactose, xylitol and malic acid, and while the pods of plants showed the more accumulation of sucrose, glucose, inulin and xylitol in bacterium treated plants...

Pentoses including xylose and arabinose are the second-most prevalent sugars of lignocellulosic biomass that can be harnessed for biological conversion. Although Yarrowia lipolytica has emerged as a promising industrial microorganism for production of high-value chemicals and biofuels, its native pentose metabolism is poorly understood. Our previous study demonstrated that Y. lipolytica (ATCC MYA-2613) has endogenous enzymes for D-xylose assimilation, but inefficient xylitol dehydrogenase causes Y. lipolytica to assimilate xylose poorly...

Arshag D Mooradian, Meridith Smith, Masaaki Tokuda
The rapid increase in the prevalence of obesity worldwide has been partially attributed to the overconsumption of added sugars. Recent guidelines call for limiting the consumption of simple sugars to less than 10% of daily caloric consumption. High intensity sweeteners are regulated as food additives and include aspartame, acesulfame-k, neotame, saccharin, sucralose, cyclamate and alitame. Steviol glycosides and Luo Han Guo fruit extracts are high intensity sweeteners that are designated as generally recognized as safe (GRAS)...

Sorbitol dehydrogenase (SDH) catalyzes the reversible oxidation of sorbitol, xylitol and ribitol to their corresponding ketoses. In this study, we investigated the expression and role of Arabidopsis SDH in salt and osmotic stress tolerance, and abscisic acid (ABA) response. The expression patterns of SDH were investigated using transgenic Arabidopsis plants expressing beta-glucuronidase (GUS) under the control of promoter with the first intron of SDH. qRT-PCR and histochemical assay of GUS activity were used to study SDH expression regulation by ABA, salt and osmotic stress...

Dental caries is an important global health concern and Streptococcus mutans has been established as a major cariogenic bacterial species. Reports indicate that a rare sugar, D‑tagatose, is not easily catabolized by pathogenic bacteria. In the present study, the inhibitory effects of D‑tagatose on the growth and biofilm formation of S. mutans GS‑5 were examined. Monitoring S. mutans growth over a 24 h period revealed that D‑tagatose prolonged the lag phase without interfering with the final cell yield...

The antifungal activity of Lactobacillus pentosus ŁOCK 0979 depends both on the culture medium and on the fungal species. In the control medium, the strain exhibited limited antagonistic activity against indicator food-borne molds and yeasts. However, the supplementation of the bacterial culture medium with polyols (erythritol, lactitol, maltitol, mannitol, sorbitol, xylitol) or their galactosyl derivatives (gal-erythritol, gal-sorbitol, gal-xylitol) enhanced the antifungal properties of Lactobacillus pentosus ŁOCK 0979...

Yeasts are good candidates to utilize the hydrolysates of lignocellulose, the most abundant bioresource, for bioproducts. This study aimed to evaluate the efficiencies of single-cell protein (SCP) and xylitol production by a novel yeast strain, Candida intermedia FL023, from lignocellulosic hydrolysates and xylose. This strain efficiently assimilated hexose, pentose, and cellubiose for cell mass production with the crude protein content of 484.2 g kg(-1) dry cell mass. SCP was produced by strain FL023 using corncob hydrolysate and urea as the carbon and nitrogen sources with the dry cell mass productivity 0...

Herein we report a simple non-enzymatic assay for xylitol and total polyols in water and oral fluid based on the time resolved formation of gold NPs in solution, and their colorimetric detection at fixed wavelength (520 nm). The key novelty of the proposed approach relies on the exploitation of information given by the early nucleation step of NPs formation instead of those related to final products at the end point of AuNPs growth, as generally reported in literature. We demonstrate that the nucleation stage is linearly correlated to the concentration of the reducing agent in solution...

The aim of the study was to assess gender related salivation features. One hundred and seventy-five patients were enrolled in the study (115 females and 60 males aged from 18 to 75 years). The study results showed xerostomia to be more common in females and it's subjective symptoms are more prominent partly because of gender-related psychological reasons. Xylitol-based paste and spray were successfully used for symptoms relief.
