(1) Background: Tocochromanols are a group of fat-soluble compounds including vitamin E (tocopherols and tocotrienols) and plastochromanol-8, and just one avocado can contain up to 20% of the required vitamin E daily intake. (2) Methods: HPLC and LC-MS/MS analyses were performed in avocados of various varieties and origin for the identification and quantification of tocopherols, tocotrienols and plastochromanol-8. After selection of the variety with the highest vitamin E content, we evaluated to what extent short- (4 h) and long-term (10 d) cold storage influences the accumulation of tocochromanols. (3) Results: Analyses revealed that “Bacon” avocados (Persea americana Mill. cv. Bacon) were the richest in vitamin E compared to other avocado varieties (including the highly commercialized Hass variety), and they not only accumulated tocopherols (with 110 µg of α-tocopherol per g dry matter), but also tocotrienols (mostly in the form of γ-tocotrienol, with 3 µg per g dry matter) and plastochromanol-8 (4.5 µg per g dry matter). While short-term cold shock did not negatively influence α-tocopherol contents, it increased those of γ-tocopherol, γ-tocotrienol, and plastochromanol-8 and decreased those of δ-tocotrienol. Furthermore, storage of Bacon avocados for 10 d led to a 20% decrease in the contents of α-tocopherol, whereas the contents of other tocopherols, tocotrienols and plastochromanol-8 were not affected. (4) Conclusions: It is concluded that Bacon avocados (i) are very rich in α-tocopherol, (ii) not only contain tocopherols, but also tocotrienols and plastochromanol-8, and (iii) their nutritional vitamin E value is negatively influenced by long-term cold storage.

Nutritional Analysis

Aim. Due to more frequent incidence of diet related diseases, alternative methods of nutrition become more popular. The aim of this paper is to determine the degree of balance of a short-term lactoovovegetarian diet followed by those who do not have any previous experience with such a diet. Moreover, the study aims at comparing its findings with results of a nutritional analysis carried out in the case of volunteers following a long-term lactoovovegetarian diet.Material and methods. The method chosen in this study is a nutritional analysis based on 7-day long nutritional surveys. Diet 5.0 software was used analyze this data. The tests were conducted among 9 lactoovovegetarians females (LVD – long-term vegetarian diet) and 9 females who decided to follow a lactoovovegetarian diet for the duration of 5 weeks (SVD – short-term vegetarian diet). In the latter case, nutritional surveys were performed in the week preceding the experiment (SVD1/control group) and the last week of the diet (SVD2).Results. In LVD group, when compared with SVD1, significant differences in average daily intake of vitamin E, fat and plant fiber have transpired. After analyzing data from nutritional surveys of SVD2 group, significant differences in the amount of basic nutritional elements (e.g. smaller amount of fat and fiber), microelements (e.g. lower supply of calcium, iron, magnesium) and vitamins (vitamin E, thiamine, niacin) have been noted, as compared to LVD group. When comparing data within SVD group, i.e. a traditional diet and a 5 week long lactoovovegetarian diet significantly lower supplies of vitamins B1, B3, B12 and D were observed than before starting the experiment. Conclusions. A short-term change of eating habits from a traditional diet into a lactoovovegetarian one may result in insufficient supply of numerous nutrients.

Abstract Synthetic seed were produced from protocorm-like bodies (PLBs) of hybrid Cymbidium Twilight Moon ‘Day Light’ after culture on a new medium, Teixeira Cymbidium (TC) medium. This new medium contained, in addition to a unique selection of macro- and micronutrients, 0.1 mg/l α-naphthaleneacetic acid and 0.1 mg/l kinetin, 2 g/l tryptone and 20 g/l sucrose, and was solidified with 8 g/l Bacto agar. Several explant types and sizes (intact PLBs, half-PLBs, PLB longitudinal thin cell layers) were tested. In addition, pretreatment of PLB-synseeds with 200 mM KNO3 solution, the addition of activated charcoal or coconut water to synseeds, light vs dark culture, short-term (1 month) and long-term (6 and 12 months) low-temperature (4°C) storage, as well as cryostorage were also tested. All treatments resulted in less PLBs than the control treatment. Among all these treatments, only the use of TC medium or incorporation of coconut water into synseeds resulted in “germination” while lowtemperature storage (1-6 months) was only possible under liquid TC. These results would allow for the short-term preservation of Cymbidium germplasm but not for effective cryopreservation.

The authors present the results of the collection’s formation of some ornamental shrubs, long-term phenological observations of them and the selection of the best forms and breeding hybrids in the Left-Bank Lisosteppe of Ukraine. In particular, the characteristic of the vegetation of 20 varieties of common lilac collection is given. The estimation of the terms and duration of the crop flowering enable to divide its varieties into groups of early, average and late flowering. The high decorative value of most of the strains has been described as well as their resistance to low temperatures and pests. The additional analysis of the latest literature data has shown the significant yield of aromatic substances in the common lilac plant, with the predominance of alkanes and lilac alcohol. The results have been presented of 70 rose cultivars of adaptation to the growing zone conditions. There are 20 promise varieties of the crop, which are characterized by high decorative value, resistance to pathogens and low temperatures and duration of flowering. The characteristics of the new variety of roses of the floribunda group – Olexandra has been given created by the authors. Along side with the high decorative value, different types of the rose plant provide the significant yield of aromatic substances with the domination of alkanes, monoterpenes and 2-phenylethanol. The analysis of the literature data also has shown the presence of aromatic substances in the jasmine and mock-orange plants. The first is characterized with esters based on benzene, cis-jasmon and isophytol, the second – with some sesquiterpenes and epi-13-manol. The further research included the phenological evaluation of the of white cedar and juniper collection. The best selected forms were characterized with decorativeness, resistance to frost, pests and pathogens. The literature data have shown, that the aromatic complex of the crops cultures includes mainly monoterpenes and their derivatives – alcohols and ketones. As a result, it was concluded that it is necessary to expand research with ornamental bushy crops in the direction of evaluating of their aromatic properties.

SUMMARY1. Four groups of eight castrated male lambs, weighing initially about 37 kg, were fed ad libitum for 18 weeks on: C, chopped dried grass throughout; P, pelleted grass throughout; C/P (or P/C), the two forms alternated every 3 weeks; or C + P, both forms on offer.2. Daily dry-matter intake (g/kg W0·75) was 58·2 for treatment C and 814 for treatment P; thus the long-term difference in intake was 40%. However, in the alternated sheep, dry-matter intake was 53·6 g/kg W0·75 for chopped grass and 86·5 g for pelleted; this short-term difference (61%) was significantly greater than the long-term difference. Dry-matter intake for treatment C+P was 84·9 g/kg W0·75; after the first week, chopped grass comprised only 10% of this. Dry-matter digestibility coefficients (%) were: C, 740; P, 61·4 and C+P, 62·0.3. The sheep were killed in week 19 and the dimensions of digestive organs and their contents were adjusted to an animal of 50 kg empty body weight. The weight of the reticulo-rumen was greater for C (1·30 kg) than for P (0·94) or C+ P (1·05), C/P and P/C being inter-mediate (1·15). The water-filled volume of the rumen was proportional to weight, except that C/P (alternated sheep finishing on pelleted grass) had low volumes. Reticulo-rumen fill was greater for C (7·28 kg) than for P (3·97) or C+ P (4·53), P/C (5·90) and C/P (4·34) being intermediate. There were no other significant differences in organs or contents.4. Gains in empty-body weight (g/day) were: C, 112; P, 181; C/P and P/C, 126; C + P, 195.

This study investigates the use of an ultrasonic sonar device—the Sonicguide™—by blind infants. Both short-term studies, lasting up to three days, and long-term studies, lasting up to two years, are reported. The importance of the selection of strict criteria for evaluating “use” of the device is emphasized. Using such criteria, age differences in ability to make effective use of the information provided by the device were found. These findings have important implications for any future intervention programs with blind infants.

1. The effectiveness of tetrathiomolybdate (TTM) in the removal of 67Cu from the long-term storage compartment in liver was studied. Lambs receiving 5 mg Cu/kg dry matter (DM) or 35 mg Cu/kg DM were primed intravenously (iv) with 67Cu and challenged 10 d later with 99Mo-labelled TTM given either iv or intraduodenally (id). The profiles of 67Cu and 99Mo and of Cu and Mo with time were measured in blood, bile, urine and faeces.2. The level of dietary Cu affected the amplitude of profiles of 67Cu and Cu in blood, bile and urine after administration of 99Mo-labelled TTM. TTM administration increased liver Cu removal and this was most marked in sheep given TTM iv. The liver Cu removal from the long-term storage Cu compartment was low and was not affected by the route of administration of TTM. Endogenous Cu excretion was higher in lambs given TTM id.3. Excretion of 67Cu in bile through the transhepatocellular pathway after TTM administration appeared absent, while the transbiliary and hepatolysosomal pathways were operative. The potential reasons for this change are discussed.4. TTM predominantly enhances the removal of Cu from the short-term storage compartment, but effects on the long-term storage compartment may still be of significance.
