BACKGROUND The objective was to evaluate the use of fruit juice with an interactive inversion recovery (IR) MR pulse sequence to visualise the gastrointestinal tract. METHODS We investigated the relaxation properties of 12 different natural fruit juices in vitro, to identify which could be used as oral contrast. We then describe our initial experience using an interactive MR pulse sequence to...

Abstract Pineapple is the most important economic plant in family Bromeliaceae and third-most economically tropical fruit world. It has become an Guangdong, Hainan, Guangxi, which are suitable areas for its cultivation. However, modern well-organized breeding systems have not yet been established pineapple. In this review, we describe current status of geographical distribution, industrial deve...

Pineapples grown in acid soils containing high levels of manganese (Mn) can exhibit iron deficiency because Mn interferes with iron bio-functioning. This situation is commonly corrected with regular iron sprays. Soil Mn concentration can be reduced by liming, but pineapple growers keep the soil pH below 5.0 because it helps reduce the incidence of rots caused by Phytophthora sp. This study was ...

Abstract Pineapple is the most exported tropical fruit in world terms of volume. This study aimed to comprehensively analyze scientific publications on pineapple, with an emphasis agricultural sciences. 7,885 documents published between 1893 and 2022 (February 22nd), 2,350 which belonged sciences, were retrieved from Scopus-indexed database be analyzed using word pineapple.

Each ommatidium of the Drosophila eye is constructed by precisely 19 specified precursor cells, generated in part during a second mitotic wave of cell divisions that overlaps early stages of ommatidial cell specification. Homozygotes for the pineapple eye mutation lack sufficient precursor cells due to apoptosis during the period of fate specification. In addition development is delayed by apop...

Tropical fruits like pineapple, papaya, mango, and beverages such as green or black teas, represent an underestimated source of antioxidants that could exert health-promoting properties. Most food processing technologies applied to fruit beverages or teas result in an impairment of inherent nutritional properties. Conversely, we hypothesise that lactic acid fermentation may constitute a promisi...

The amino acid sequences of ananain (EC3.4.22.31) and stem bromelain (3.4.22.32), two cysteine proteases from pineapple stem, are similar yet ananain and stem bromelain possess distinct specificities towards synthetic peptide substrates and different reactivities towards the cysteine protease inhibitors E-64 and chicken egg white cystatin. We present here the complete amino acid sequence of ana...

The relationships between Rotylenchulus reniformis population densities and pineapple growth and yield were studied in a small-plot field experiment. Increasing rates of handgun-injected 1,3-dichloropropene (1,3-D) preplant fumigant from 0 to 337 liters/ha resulted in greater nematode control, faster plant growth, and larger pineapple fruits. Rotylenchulus reniformis population densities at 2, ...

Abstract The authors conducted a survey of Pineapple Mealybug Wilt-associated Virus (PMWaV) on pineapple plants in four pineapple-producing sub-districts North Tapanuli, namely Sipahutar, Pangaribuan, Siborongborong, and Tarutung. This aims to detect the presence distribution PMWaV Tapanuli. found all locations with varying symptoms such as wilting yellow-red colour curling leaf tips, drying le...

One major problem with frozen fruits is a loss of texture. Therefore this study investigated the effects of the freezing process on the freezing profiles, texture, and drip loss of apple, mango, cantaloupe, and pineapple fruit samples. All frozenthawed fruits varied in these three properties because of diversity in the fresh fruits. Mango had the highest total soluble solids content and the low...
