Regulation of cell growth and proliferation is crucial for development and function of organs in all animals. Genetic defects in growth control can lead to developmental disorders and cancers. Translationally controlled tumor protein (TCTP) is a family of evolutionarily conserved proteins implicated in cancer. Recent studies have revealed multiple roles of TCTP in diverse cellular events, but TCTP functions in vivo are poorly understood in vertebrate systems. We have used Drosophila melanogaster, the fruit fly, as a model organism for genetic dissection of Tctp function...

Lutein, a yellow xanthophyll carotenoid found in egg yolks and many colorful fruits and vegetables, has gained public health interest for its putative role in visual performance and reducing the risk of age-related macular degeneration. The National Academies of Sciences, Engineering and Medicine's recommended Dietary Reference Intakes (DRIs) focus on preventing deficiency and toxicity, but there is a budding interest in establishing DRI-like guidelines for non-essential bioactives, like lutein, that promote optimal health and/or prevent chronic diseases...

Tomato is a high value crop and the primary model for fleshy fruit development and ripening. Breeding priorities include increased fruit quality, shelf life and tolerance to stresses. To contribute towards this goal, we re-sequenced the genomes of Corbarino (COR) and Lucariello (LUC) landraces, which both possess the traits of plant adaptation to water deficit, prolonged fruit shelf-life and good fruit quality. Through the newly developed pipeline Reconstructor, we generated the genome sequences of COR and LUC using datasets of 65...

Evidence on the association between sleep, diet, and eating behaviors in pregnant women is lacking. We examine this in a cohort of apparently healthy pregnant women. At 26-28 weeks gestation, 497 participants completed the Pittsburgh Sleep Quality Index to assess sleep and a 24-h recall to assess dietary intake. Diet quality was assessed by the Healthy Eating Index for pregnant women in Singapore (HEI-SGP) score and previously derived dietary patterns (vegetables-fruit-rice, seafood-noodles, and pasta-cheese-meat pattern)...

Dietary factors play a major role in the development of colorectal cancer. This study evaluated the reproducibility and validity of a 109-food item Food Frequency Questionnaire (FFQ) to measure the consumption of foods and nutrients related to the development of colorectal cancer in a population aged ≥50 years in Flanders, Belgium. A semi-quantitative FFQ was administered two times in a period of two weeks to evaluate reproducibility (FFQ1 and FFQ2). The validity of the FFQ was assessed by comparing FFQ1 against the 3-day diary method (3 DD)...

Wild fruits are commonly consumed in the rural communities of South Africa. The information on their nutritionally important fatty acids is, however, limited. Three wild fruit species, Diospyros blancoi, Landolphia kirkii and Sclerocarya birrea from Limpopo Province were selected for evaluation of fatty acid content. Fatty acids composition of dried fruits of Diospyros blancoi (Db), Landolphia kirkii (Lk) and ripe and/or overripe Sclerocarya birrea (Sb) were evaluated by a gas chromatography-time of flight-mass spectrometer (GC-TOF-MS)...

BACKGROUND: Previous studies in adults and older children find that sugar-sweetened beverage (SSB) consumption increases risk for obesity and cellular aging, as measured by leukocyte telomere length (LTL). METHODS: In a previously described, San Francisco-based Latino birth cohort, where telomere length was measured at birth, we evaluate the relationship between beverage consumption (including SSB and 100% fruit juice), obesity, and LTL at 2-3 years old, as well as change in LTL from birth...

Ethylene response factor (ERF) has been widely studied in regulating fruit ripening in tomato, apple, banana and kiwifruit, but little is known in pear. In this study 1-methylcyclopropene (1-MCP) treatment, an inhibitor of ethylene perception, was conducted at approximately 30 days before harvest to delay fruit ripening in a climacteric white pear cultivar Yali. Transcriptome libraries were constructed and sequenced in pre-ripening, ripening, and 1-MCP treated fruits. Data analysis showed that 73 candidate genes related to fruit ripening were induced by 1-MCP, among which two were positively related, namely 1-aminocyclopropane-1-carboxyla oxidase and an ERF gene (designated as ACO54 and ERF24)...

We assessed community residents' perceptions of corner stores to better understand what facilitates and deters patronage at these food outlets. Data came from 978 household interviews in 2 Latino communities undergoing corner store interventions. Chi-square tests, an independent sample t test, and a multivariate logistic regression were conducted to assess the relationship between residents' perceptions about corner stores and their reported patronage at these food outlets. Residents reported that corner stores do not sell a variety of fruits and vegetables and are not places where one can get information about healthy eating...

The Serra Gaúcha region is the most important temperate fruit-producing area in southern Brazil. Despite mealybugs (Hemiptera: Pseudococcidae) infesting several host plants in the region, there is a lack of information about the composition of species damaging different crops. A survey of mealybug species associated with commercial fruit crops (apple, persimmon, strawberry and grapes) was performed in Serra Gaúcha between 2013 and 2015, using both morphology and DNA analyses for species identification. The most abundant species were Pseudococcus viburni (Signoret), found on all four host plant species, and Dysmicoccus brevipes (Cockerell), infesting persimmon, vines and weeds...

Flying insects routinely forage in complex and cluttered sensory environments. Their search for a food or a pheromone source typically begins with a whiff of odor, which triggers a flight response, eventually bringing the insect near the odor source. However, pinpointing the precise location of an odor source requires use of both visual and olfactory modalities, aided by odor plumes. Here, we investigated odor-tracking behavior in fruit flies (Drosophila melanogaster) presented with low- or high-contrast visual landmarks, either paired with or separate from an attractive odor cue...

Euterpe oleracea (Açaí) fruit are widely consumed at the Brazil Amazon region, and biological potentials such as immunomodulatory and antioxidant have been described for its extracts. However, its antimicrobial effect remains poorly investigated. In this study, the antimicrobial and antibiofilm activities of the methanolic extract of an artisanally-manufactured açaí pulp (MEAP) were evaluated against clinical isolates of Staphylococcus aureus. Besides, MEAP interference on the activity of antimicrobial drugs of clinical relevance was explored, and its cytotoxicity against hepatocellular carcinoma cells (HepG2) was investigated...

In protected vegetable fields, plant growth regulators are often used to improve cucumber fruit growth. However, the effects of plant growth regulators on the appearance and nutritional quality of cucumber (Cucumis sativus L.) remain largely unknown. In the present study, 100 mg/L N-(2-chloro-4-pyridyl)-N'-phenylurea (CPPU), naphthaleneacetic acid (NAA) or gibberellin A4+A7 (GA4+7) was applied to the female cucumber flowers 1 day before anthesis and at anthesis. The CPPU, NAA and GA4+7 treatments resulted in parthenocarpic fruits with similar weights, sizes and shapes as the pollinated fruits...

Oleocellosis is a serious physiological disorder in citrus fruit that mainly results in appearance and quality deterioration. It has been well established that the occurrence of oleocellosis is highly correlated with the release of peel oil from citrus fruit, while there is little information on the dynamic changes in the content of the volatile constituents and the expression of genes involved in terpenoid metabolism during oleocellosis development. In the present research, large changes in the volatile profiles and gene expression in terpenoid metabolism were observed in oleocellosis peels compared to healthy ones...

In this study, the degradation of polysaccharides from blackcurrant (BCP) was investigated. Two low-molecular-weight polysaccharides (DBCP-1, DBCP-2) were obtained using Fe(2+) with different concentrations of H2O2 solution. IR spectra showed DBCPs had obvious characteristic peaks of polysaccharides. GC analysis confirmed DBCPs were composed of the same monosaccharide units as BCP but with different molar ratios. NMR analysis indicated DBCPs and BCP had similar glycosidic linkage patterns. The surface area of fragmented structure in DBCPs was reduced compared to BCP, and they had no triple helix structure...

Fresh-cut (FC) red pitaya fruit were treated with 5ga.i.l(-1) apple polyphenols (APP) and then stored at 20°C for up to 4days to evaluate the effects on attributes. Results showed that FC pitaya fruit with APP treatment showed greater colour retention, delayed softening, reduced loss of soluble solids content, titratable acidity, betacyanin and total phenolics compared with untreated FC fruit. APP treatment also maintained antioxidant activity, as indicated by higher DPPH radical-scavenging activity and reducing power compared with untreated FC pitaya fruit...

N(ε)-carboxymethyl-lysine (CML) is measured in food, but there is a controversy concerning the most convenient yet reliable method(s) for this task. This work compares three different ELISA assays and HPLC-ESI-ITMS/MS for the analysis of CML in several food items. The four methods showed the same decreasing order of CML concentration: beef, bacon>chicken > fish>dairy products>grain products>fruits/vegetables. HPLC-ESI-ITMS/MS results highly correlated with those obtained by ELISA performed with monoclonal CML-antibody (β=0...

For the first time, the influence of different vine management was evaluated in relation to volatile profile and sensory perception through GC×GC/TOFMS, QDA, GC-FID, GC/MS, and GC-O. GC×GC/TOFMS analyses and QDA have shown that a larger spacing between vine rows (2 rather than 1m), attachment of shoots upwards, and irrigation did not result in wine improvement. Conversely, wines elaborated with grapes from a vine with a lower bud load (20 per plant; sample M1) stood out among the other procedures, rendering the most promising wine aroma...

Pseudomonas syringae pv. syringae van Hall CFCC 1336 (Pss 1336) is the causal agent of bacterial disease of stone fruit trees, and also able to elicit hypersensitive response (HR) in non-host tobacco. It is known that this pathogen uses PCS-pathway to synthesize phosphatidylcholine (PC), and mutation of the pcs gene abolishes bacterial PC synthesis. Previous study also found that the 1336 pcs(-) mutant lacking PC in its membrane phospholipids was unable to secrete HrpZ harpin and elicit HR in non-host plants...
