Abstract:
High sugar intake may increase cancer risk by promoting insulin–glucose dysregulation, oxidative stress, inflammation, and body adiposity, but epidemiologic evidence is unclear. Associations between dietary sugars and lifestyle-related cancer risk from longitudinal studies were evaluated. We systematically searched PubMed, Embase, and CINAHL and identified 37 prospective cohort studies (1990–2017) reporting multivariable adjusted risk estimates for dietary sugars in relation to cancer. Of 15 and 14 studies on total sugar and sucrose respectively, 11 reported a null association in relation to cancer. Of 14 studies on fructose, 8 reported null associations, and 2 reported protective and 4 reported detrimental associations. In two of five studies on added sugars, a 60–95% increased cancer risk was observed with higher intakes. In 8 of 15 studies on sugary foods and beverages, a 23–200% higher cancer risk was observed with higher sugary beverage consumption. In conclusion, most studies were indicative of a null association, but suggestive detrimental associations were reported for added sugars and sugary beverages.

Abstract:
Abstract Objectives Inconsistencies in prospective studies investigating sugars and sweeteners with health may be partly due to inaccurate self-reported intake estimates. We compared the relative validity of two self-reported dietary methods and urinary biomarkers to estimate the intake of sugars and sweeteners using data of free-living Dutch adults. Methods We included 848 participants with one food frequency questionnaire (FFQ) and ≥3 24-h recalls from the NQplus study. Intakes of sugars (mono and disaccharides, sucrose, fructose, free sugars, and added sugars), sugary foods, and sweetened beverages (sugar-sweetened beverages (SSB), Low/Non-calorie beverages (LNCB), and fruit juice) were estimated by using the Dutch food composition table. A sub-sample of 288 participants provided 3 repeated urine samples to measure the urinary sugar and sweetener concentrations. Measurement error models were used to calculate, ICCs, proportional scaling bias (βx), validity coefficients (VC), and attenuation factors (AF). Results According to 24 h-recall data, most sugars and sweet foods/beverages had a high day-to-day variation (ICC ≤ 0.56). Under-reporting (βx < 1) between the FFQ and the multiple recalls was highest for sugary foods and beverages (0.57 to 0.66), and lowest for sugars (0.68 to 0.81). VCs ranged from 0.49 (sugary foods) to 0.74 (SSB), suggesting a moderate to good agreement between the methods for most sugars and for sweet beverages. AFs ranged from 0.42 (sugary foods) to 0.96 (SSB), indicating that the FFQ tends to underestimate the associations between sugars or sweet foods and disease compared to the recalls. The high AFs for LNCB (0.93) and SSB (0.96) suggested that the under-estimation of the diet-disease association was minimal for these beverages when using the FFQ instead of recalls. Compared to men, women showed more day-to-day variation, more under-reporting, and lower VC and AF, except with LNCB. In general, only slight differences between BMI categories were observed. Results of the biomarkers are expected in April. Conclusions Overall, the FFQ showed moderate to good ranking performance compared to multiple 24 h-recalls for sugars and sweet foods.

Abstract:
A high consumption of sugar leads to an increase in caloric intake, which in turn will lead to a higher risk of developing health issues. Foods contain both naturally occurring sugars and added sugars. The World Health Organization recommends that the daily intake of free sugars be below 10% of the total daily energy intake. Food performs a key role in maintaining an adequate glycaemic control in people with diabetes. However, there is a low compliance to dietary recommendations, namely in the amount of sugar intake. This review article aims to assess and compare the intake of various types of sugars in the general population and among individuals with and without a diabetes diagnosis, identify the food sources that contribute to the intake of free and added sugars, and understand their impact on health. Studies performed on the general population found that the consumption of sugar was high, and that children and teens are more likely to exceed the recommended amounts. It was found that diabetics consume less total and added sugar than non-diabetics, as well as a less sugary drinks. Guidelines and public health policy measures aimed at limiting the intake of free and added sugars are needed in order to minimize the consumption of foods high in empty calories.

Abstract:
This thesis describes the synthesis of 2-C-branched carbohydrate derivatives from ketohexoses and some useful synthetic applications thereof. Chapter 1 encompasses a general introduction to branched-chain sugars, with the emphasis upon 2C- hydroxymethyl and -methyl branched sugars. Strategies for their synthesis are discussed, both from nucleophilic and electrophilic carbohydrate derivatives. Some synthetic applications of carbohydrates and consequently branched carbohydrates are highlighted, with a view to the derivatisation of a proposed chiron from the Kiliani ascension of L-sorbose, 2-C-hydroxymethyl2,3: 5,6-di-O-isopropylidene-L-gulono,1,4-lactone. In chapter 2, the Kiliani ascension of L-sorbose and two subsequent complementary di-O-isopropylidene protections of the branched-chain lactones generated (thermodynamic and kinetic) are discussed. Further studies into the same transformations of three other ketohexoses, D-fructose, D-tagatose and D-psicose are then discussed. Further useful synthetic derivatives of the three major isomeric L-sorbose-derived branched di-protected lactones: selective deprotections and cleavage of C5-C6 bonds. One major area wh!ch utilizes carbohydrate building blocks is iminosugar synthesis. Iminosugars are the major compound class of interest in the realm of glycosidase inhibition, and also have other therapeutic properties, thus making them desirable synthetic targets. The application of 2-C- . branched sugar derivatives in the synthesis of novel iminosugars is proposed. Chapter 4 describes the syntheses of eight novel 2-C- hydroxymethyl and -methyl branched iminosugars from the major thermodynamic product (2-C-hydroxymethyl-2,3 :5,6-di-O-isopropylidene-L-gulono-l ,4-lactone) obtained from the Kiliani ascension of L-sorbose, as described in chapter 2. The syntheses of two additional novel iminosugars from isomeric 2,3:5,6-di-O-isopropylidene branched derivatives is described. Some results of inhibitory activity follow the synthetic results. The last two chapters provide a general introduction to macrocycles, and some synthetic investigations into macrocycles based on open-chain sugar amino acids (SAAs). SAA-derived macrocycles are structural hybrids of macrocyclic peptides and cyclodextrins. Strategies for the synthesis of large rings and previous work on D-galactose-derived-SAA macrocycles within the group is described with a view to the extension of this work towards novel asymmetric macrocycles with functionalisable rings. Chapter 6 reports synthetic investigations into three related families of macrocycles, each based on an open-chain galacto SAA. The pure galacto SAA macrocycles are revisited and two novel families of macrocycles are born, one containing proteinogenic amino acids and the other incorporating branched-chain SAAs. The branched-chain SAA itself is derived from 2-C-hydroxymethyl-2,3 :5,6-di-O-isopropylidene-D-mannono-l ,4-lactone, the major protected Kiliani lactone derived from D-fructose. Two major improvements to the original methodology for macrocycle formation are reported. Some structural analysis of macrocylic compounds through NMR and CD spectroscopy.

Abstract:
This thesis describes the synthesis of three novel seven carbon bicyclic mimics of α-L-fucose, and of two new pyrrolidine amino sugars. 2,7-Anhydro- l-deoxy-β-L-gulo-heptulopyranose and l,2,7-trideoxy-2,7-imino-β- L-gulo-heptulopyranose were both synthesised from L-gulono-l,4-lactone. The addition of one equivalent of methyllithium to the diacetonide of L-gulono-1,4- lactone gave a keto-sugar, l-deoxy-3,4;6,7-di-0-isopropylidene-β-L-gulo- heptulofuranose. The anomeric configuration of this compound was determined by equilibrium nOe measurements. Hydrolysis in aqueous trifluoroacetic acid caused simultaneous deprotection, isomerisation and dehydration to yield 2,7-anhydro-l-deoxy-β-L-guloheptulopyranose, a highly stable, rigid bicyclic system. The structure of the bicyclic system was confirmed by X-ray crystallographic studies on a crystalline derivative. The introduction of nitrogen at C-6 of L-gulono-l,4-lactone was achieved via the azide displacement of the known bromide, 6-bromo-6-deoxy-2,3-0- isopropylidene-L-gulono-l,4-lactone. Protection of the C-5 hydroxyl group as its silyl ether was followed by the addition of one equivalent of methyllithium to the carbonyl group to give a keto-sugar, 7-azido-6-(0-tert-butyldimethylsilyl-l,7- dideoxy-3,4-0-isopropylidene-β-L-gulo-heptulofuranose. Removal of the protecting groups followed by reduction of the azide functionality gave the bicyclic hemiaminal, l,2,7-trideoxy-2,7-imino-β-L-gulo-heptulopyranose, a stable but hygroscopic solid. A third bicyclic system, 2,7-anhydro-l,2,6-trideoxy-2,6-imino-β-L-gulo- heptulopyranose, was synthesised from diacetone-D-mannose via the known ketosugar, 6-azido-7-0-tert-butyldimethylsilyl-l,6-dideoxy-3,4-0-isopropylidene-β- L-gulo-heptulofuranose. Removal of the protecting groups from this keto-sugar, followed by reduction of the azide functionality, gave the target system. Analysis of the NMR spectra showed that this existed as an equilibrium mixture of the closed, bicyclic hemiaminal form and the monocyclic imine form, with the bicyclic form predominating in all solvents investigated. The sodium borohydride reduction of l-deoxy-3,4;6,7-di-0-isopropylidene-β-L-gulo-heptulofuranose gave a single product, the heptitol 7-deoxy-l,2;4,5-di-0-isopropylidene- L-glycero-D-gluco-heptitol. This was converted into two novel pyrrolidine amino sugars, l,2,5-trideoxy-2,5-imino-L-glycero-L-allo-heplitol and l,2,5-trideoxy-2,5-imino-L-allitol. The two free hydroxyl groups in the heptitol were converted into leaving groups and one was then displaced selectively with sodium azide. Reduction of the azide functionality gave an amine which cyclised onto the remaining leaving group to form the pyrrolidine framework. Complete deprotection of this product gave l,2,5-trideoxy-2,5-imino-L-glycero-L-allo- heptitol, the structure of which was confirmed by X-ray crystallographic studies on a crystalline derivative. Removal of the primary acetonide from the cyclisation product and subsequent periodate cleavage gave an aldehyde which was then reduced to an alcohol. Deprotection then gave the second pyrrolidine amino sugar l,2,5-trideoxy-2,5-imino-L-allitol. The effect of all five target compounds on eleven human liver glycosidase enzymes was investigated, and these results are also reported.

Full text
Abstract:
Poplar wood can be used as feedstocks for manufacturing of cellulosic biofuels (e.g., ethanol) as liquid transportation fuels. Producing ethanol from poplar wood involves reducing poplar wood into small particles, hydrolyzing cellulose inside poplar particles to fermentable sugars, and converting these sugars to ethanol. Size reduction is usually done by wood chipping and biomass milling. In the literature on poplar biofuels, there are no reports on particle formation mechanisms or effects of size reduction on sugar yield. One important reason for the lack of such knowledge is that particle formation in current size reduction methods is not well controlled. This paper presents the first attempt to use a lathe to generate poplar particles (or chips) with well controlled mechanisms of chip formation. The objective is to experimentally determine relations among chip thickness, uncut chip cross-section area, shear angle (representing the deformation severity of the chips), crystallinity index, and sugar yield.

Abstract:
The use of biodegradable polymers from renewable resources in polymer manufacturing, food packaging and for medical application is becoming a favorable option over petroleum-based plastics. Among all biopolymers, biopolyesters poly(lactic acid) (PLA) and polyhidroxyalkanoates (PHAs) are considered as the most commercially promising bioplastics. PLA is a biopolyester produced by polymerization of D-, L- lactic acids originating through fermentation of simple sugars from agricultural sources (corn, potato, sugar cane, sugar beet, etc.). PHA is a generic designation for biopolyesters produced by controlled microbial fermentation in the presence of an abundant source of sugars or lipids. The focus of this study was to prepare fully biodegradable flexible nanomaterials using PLA and poly(hydroxybutyrate) (PHB) polymer blend solution by means of electrospinning technique. Since PHB possesses low resistance to thermal degradation with melting temperatures close to degradation and narrowing the processing window, the electrospinning technique reduces energy consumption and avoids thermal degradation during processing. A complete morphological, structural and thermal characterization of the developed materials was conducted at the same time.

Abstract:
Water is the major limiting factor in agriculture and stomata, composed of two guard cells and the pore they circumscribe, are the chief gates controlling plants’ water loss. The prevailing century old paradigm was that sugars act as an osmoticum in guard cells, contributing to the opening of the stomata. In contrast, we discovered that sugars close stomata and the closure is mediated by the sugar-sensing enzyme hexokinase (HXK) that triggers the abscisic acid (ABA)-signaling pathway within the guard cells. This new discovery suggests a sugar-sensing mechanism within guard cells that controls stomatal closure, and supports the existence of a stomatal feedback mechanism that coordinates photosynthesis with transpiration.

Abstract:
The involvement of glycans in microbial adherence, recognition and signaling is often a critical determinant of pathogenesis. Although the major glycan components of fungal cell walls have been identified there is limited information available on its ‘minor sugar components’ and how these change during different stages of fungal development. Our aim was to define the role of Rhacontaining-glycans in the gray mold disease caused by the necrotrophic fungus B. cinerea. The research was built on the discovery of two genes, Bcdhand bcer, that are involved in formation of UDP-KDG and UDP-Rha, two UDP- sugars that may serve as donors for the synthesis of cell surface glycans. Objectives of the proposed research included: 1) To determine the function of B. cinereaBcDh and BcEr in glycan biosynthesis and in pathogenesis, 2) To determine the expression pattern of BcDH and BcERand cellular localization of their encoded proteins, 3) Characterize the structure and distribution of Rha- containing glycans, 4) Characterization of the UDP-sugar enzymes and potential of GTs involved in glycanrhamnosylation. To address these objectives we generated a series of B. cinereamutants with modifications in the bchdhand bcergenes and the phenotype and sugar metabolism in the resulting strains were characterized. Analysis of sugar metabolites showed that changes in the genes caused changes in primary and secondary sugars, including abolishment of rhamnose, however abolishment of rhamnose synthesis did not cause changes in the fungal phenotype. In contrast, we found that deletion of the second gene, bcer, leads to accumulation of the intermediate sugar – UDP- KDG, and that such mutants suffer from a range of defects including reduced virulence. Further analyses confirmed that UDP-KDG is toxic to the fungus. Studies on mode of action suggested that UDP-KDG might affect integrity of the fungal cell wall, possibly by inhibiting UDP-sugars metabolic enzymes. Our results confirm that bcdhand bcerrepresent a single pathway of rhamnose synthesis in B. cinerea, that rhamnose does not affect in vitro development or virulence of the fungus. We also concluded that UDP-KDG is toxic to B. cinereaand hence UDP-KDG or compounds that inhibit Er enzymes and lead to accumulation of UDP-KDG might have antifungal activity. This toxicity is likely the case with other fungi, this became apparent in a collaborative work with Prof. Bart Thomma of Wageningen University, NETHERLANDS . We have shown the deletion of ER mutant in Verticillium dahlia gave plants resistance to the fungal infection.
