Simon Baeckens, Roberto García-Roa, José Martín, Raoul Van Damme
Lizards communicate with others via chemical signals, the composition of which may vary among species. Although the selective pressures and constraints affecting chemical signal diversity at the species level remain poorly understood, the possible role of diet has been largely neglected. The chemical signals of many lizards originate from the femoral glands that exude a mixture of semiochemicals, and may be used in a variety of contexts. We analyzed the lipophilic fraction of the glandular secretions of 45 species of lacertid lizard species by gas chromatography/mass spectrometry...

BACKGROUND: Ectophytic fungi occupy the waxy plant surface, an extreme environment characterized by prolonged desiccation, nutrient limitation, and exposure to solar radiation. The nature of mechanisms that facilitate adaptation to this environment remains unclear. In this study, we sequenced the complete genome of an ectophytic fungus, Ramichloridium luteum, which colonizes the surface of apple fruit, and carried out comparative genomic and transcriptome analysis. RESULTS: The R...

<p>Seborrheic keratosis (SK) is a benign epidermal keratinocytic tumor that is extremely common, particularly in individuals over the age of 50. Most individuals with SK will have more than one lesion and the presence of over 10 lesions in the same person is not uncommon. Although the clinical morphology of most SK with their stuck-on, symmetric, keratotic, and waxy appearance makes them easy to identify, many manifest a morphology resembling melanoma or squamous cell carcinoma. One can argue that such cases will ultimately not prove to be problematic since a simple biopsy will easily reveal their benign nature and eliminate any concerns...

Litao Yang, Sheng Quan, Dabing Zhang
Endogenous reference genes (ERG) and their derivate analytical methods are standard requirements for analysis of genetically modified organisms (GMOs). Development and validation of suitable ERGs is the primary step for establishing assays that monitoring the genetically modified (GM) contents in food/feed samples. Herein, we give a review of the ERGs currently used for GM wheat analysis, such as ACC1, PKABA1, ALMT1, and Waxy-D1, as well as their performances in GM wheat analysis. Also, we discussed one model for developing and validating one ideal RG for one plant species based on our previous research work...

Background Tablets and capsules are the most accepted and widely used solid dosage forms in the medical therapy. Flow property of the powders is playing a key role in the various pharmaceutical fields especially in the fomulation of tablets and capsules. The high hygroscopic crystalline structure of anhydrous Divalproex sodium (DVX) makes it to be appear as waxy white flakes with almost no powder flowability which cause serious problems during the tabletting and capsule filling procedures. Purpose The main objective of this study was to improve the flowability of DVX powder...

Dextrinization of starch using extrusion processing is crucial to the quality of direct expanded products. To determine the extent of dextrinization, flour samples were extracted from a twin-screw extruder that had been brought to a sudden stop and molecular weights were determined by intrinsic viscosity. The screw profile and moisture feed content had the most significant impact on molecular weight reduction, reducing intrinsic viscosity from 1.75 to 0.70dL/g at the most. The breakdown, as shown by a reduction in intrinsic viscosity, had a strong negative correlation (r=-0...

The blueberry fruit has a light-blue appearance because its blue-black skin is covered with a waxy bloom. This layer is easily damaged or removed during fruit harvesting and postharvest handling. We investigated the effects of wax removal on the postharvest quality of blueberry fruit and their possible mechanisms. The removal of natural wax on the fruit was found to accelerate the postharvest water loss and decay, reduce the sensory and nutritional qualities, and shorten the shelf-life. Wax removal decreased the activities of antioxidant enzymes and contents of antioxidants, and accelerated accumulation of ROS and lipid peroxidation, especially at the later period of storage...

BACKGROUND: Chemical signals are widely used in the animal kingdom, enabling communication in various social contexts, including mate selection and the establishment of dominance. Femoral glands, which produce and release waxy secretions into the environment, are organs of central importance in lizard chemical communication. The Galápagos marine iguana (Amblyrhynchus cristatus) is a squamate reptile with a lek-mating system. Although the lekking behaviour of marine iguanas has been well-studied, their potential for sexual communication via chemical cues has not yet been investigated...

The effects of acid hydrolysis intensity on the physicochemical properties of starch/xanthan gum (XG) system were studied. Waxy corn starch (WCS) was subjected to different concentrations of hydrochloric acid, and crystallization and relative molecular weight analysis were performed. The results revealed that the starch granules became smaller during acid hydrolysis. X-ray diffraction pattern analysis showed that the crystal structure did not change with acid hydrolysis. Evaluation of the properties and digestibility of different acid-thinned starch/XG systems indicated that the viscosity of acid-thinned starch/XG decreased with increased acid hydrolysis intensity...

This study was aimed at determining the effect of the amylose content of starch and oxidation level of potato starch on the structure of starch granules, and susceptibility to chemical modification (acetylation) and subsequent generation of radicals. Potato starch and waxy potato starch were oxidised with sodium hypochlorite applied in doses corresponding to 10, 20, and 30gCl/kg starch, and then acetylated with acetic acid anhydride. The carboxyl, carbonyl, acetyl groups were determined in modified starches...

Starch is the most abundant storage carbohydrate in maize kernel. The content of amylose and amylopectin confers unique properties in food processing and industrial application. Thus, the resurgent interest has been switched to the study of individual amylose or amylopectin rather than total starch, whereas the enzymatic machinery for amylose synthesis remains elusive. We took advantage of the phenotype of amylose content and the genotype of 9,007,194 single nucleotide polymorphisms (SNPs) from 454 inbred maize lines...

Self-assembled monolayers (SAMs) have emerged as a simple platform technology and hence have been broadly studied. With advances in state-of-the-art fabrication and characterization methods, new insights into SAM structure and related properties have been delineated, albeit with some discrepancies and/or incoherencies. Some discrepancies, especially between experimental and theoretical work, are in part due to the misunderstanding of subtle structural features such as phase evolution and SAM quality. Recent work has, however, shown that simple techniques, such as the measurement of static contact angles, can be used to delineate otherwise complex properties of the SAM, especially when complemented by other more advanced techniques...

The neuroprotectant and memory enhancer supplement for menopause is required due to the side effects of hormone replacement therapy. Since purple waxy corn cob and pandan leaves exert antioxidant and acetylcholinesterase inhibition (AChEI) effects, we hypothesized that the combined extract of both plants (PCP) might provide synergistic effect leading to the improved brain damage and memory impairment in experimental menopause. To test this hypothesis, female Wistar rats were ovariectomized bilaterally and orally given various doses of the functional drink at doses of 20, 40, and 80 mg/kg for 28 days...

The effects of the molecular structures of amylopectins on the enzymatic hydrolysis of waxy-rice amylopectin (WRA) and normal-rice amylopectin (NRA) were investigated. The results indicated that compared to NRA, WRA possessed larger chain length, number of chains, internal chain length, degree of polymerisation, interblock chain length, and lower degree of branching and short:long B-chains, which caused WRA was much less susceptible to enzymatic hydrolysis than NRA. The digestibility curves for WRA and NRA were well fitted by the first-order kinetic equation...

This study aimed to investigate the effects of different dietary starch types on early postmortem muscle energy metabolism in finishing pigs. Ninety barrows (68.0±2.0kg) were randomly allotted to three experimental diets with five replicates of six pigs, containing pure waxy maize starch (WMS), nonwaxy maize starch (NMS), and pea starch (PS) (amylose/amylopectin were 0.07, 0.19 and 0.28 respectively). Compared with the WMS diet, pigs fed the PS diet exhibited greater creatine kinase activity, higher adenosine triphosphate and adenosine diphosphate contents, lower phosphocreatine (PCr), adenosine monophosphate and glycogen contents, and lower glycolytic potential (P<0...

BACKGROUND: Waxy maize (Zea mays L. sinensis Kulesh) suffers short-term exposure to high temperature during grain filling in Southern China. The effects of such exposure are poorly understood. RESULTS: Starch granule size was increased by 5 d short-term heat stress (35 °C) and the increase was higher when the stress was introduced early. Heat stress increased the iodine-binding capacity of starches and no difference was observed among the three stages. Starch relative crystallinity was increased and swelling power was decreased only when heat stress was introduced early...

Hollow fibers materials have been potentially used and gaining increasing attention in recent years. In this study, Egyptian hollow fibers have been blended with cotton and polyester wastes at different weft counts using open-end spinning. The blended fabrics were subjected for cationisation followed by printing with reactive and acid dyes. The performance of impact properties of cationised hollow fiber reinforced polyester/cotton hybrid composites was studied. The results demonstrated that the physical and color properties of blended fabrics are greatly influenced by alkali pretreatment and cationisation of hybrid composites as well as the weft counts...
