Abstract The aim of the investigations was to determine the best method of eggplant (Solanum melongena L.) pruning in greenhouse production. The investigations were carried out in 1999 - 2001 in the experimental greenhouse of the University of Agriculture in Krakow, Poland. The ‘Tania F1’ hybrid was used in the early spring-summer production in a heated greenhouse. Plants were pruned to one or two shoots. In the case of two-shoot plants, the second shoot was led out from the first, third, sixth and ninth node. The intense pruning positively affected the PAR conditions in the plant profile. The most effective fruit setting was observed in the intensely pruned plants. The greatest number of fruits was set at the lowest nodes. Pruning affected the total but not marketable yield of fruits. Two-shoot plants with the second shoot led out from the sixth node produced the greatest fruits, both in early and total yield. A high level of reducing sugar was found in the fruits of moderately pruned plants. Fruits of two-shoot plants with the second shoot led out from the sixth node and pruned to one shoot contained the greatest level of L-ascorbic acid. The greatest levels of reducing sugar and starch were found in the leaves of moderately pruned plants, having the best PAR conditions. The method of pruning slightly affected the level of pigments in the eggplant leaves.

Twenty two brinjal (Solanum melongena L.) genotypes were collected and grown in summer season and variability estimates were studied for twenty two different quality, yield, its attributing traits. High genotypic and phenotypic coefficient of variation was obtained for characters like length of style, fruit girth, average fruit weight, number of fruits per plant, yield per plant, total yield per hectare, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. Heritability and genetic gain as percent of mean was observed to be high for characters such as plant height, number of primary branches, length of style, fruit length, fruit girth, average fruit weight, number of fruit per plant, yield per plant, total yield per hectare, TSS, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. High heritability coupled with high predicted genetic gain suggests for selection based on these traits for enhancement of yield and quality.

Due to the increase of the organic cultivation of beetroot and its growing importance as a functional food, the potential advantages of open-pollinated genotypes as an alternative for F1 hybrid genotypes has been investigated. In this regard, six field experiments were carried out in 2017 and 2018 in three different locations to investigate the agronomic potential of new and existing open-pollinated genotypes of beetroot and their performance under the specific conditions of organic agriculture. Fifteen beetroot genotypes, including one F1 hybrid as a commercial control and one breeding line, were compared regarding their total and marketable yield, individual beet weight, diameter of beet, and leaves-growth-base width. Furthermore, five randomly selected beetroots meeting common marketable criteria were evaluated optically with regard to skin smoothness, corky surface, root tail, scab incidence, and uniformity. Results of this study indicated a significant impact of genotype on eight of the assessed traits. The cylindrical-shaped genotype, Carillon RZ, demonstrated significantly higher total and marketable yields, with 53.28 ± 3.34 t ha−1 and 44.96 ± 3.50 t ha−1, respectively, compared to the yellow-colored genotype, Burpees Golden, which obtained the lowest total yield, 36.06 ± 3.38 t ha−1, and marketable yield, 27.92 ± 3.55 t ha−1. Moreover, the comparison of the open-pollinated genotypes with the F1 hybrid, Monty RZ F1, revealed that except for the traits yield, scab, and uniformity, the open-pollinated genotypes indicated desirable competitive outcomes and thus offer suitable alternatives for organic cropping systems. Overall, the observed genetic variability can be beneficial for breeding and food product development.

Abstract The University of Malaya Medical Centre, Kuala Lumpur had acquired a intraoperative MRI (iMRI) brain suite via a public private initiative in September 2015. The MRI brain suite has a SIEMENS 1.5T system with NORAS coil system and NORAS head clamps in a two room solution. We would like to retrospectively review the cranial paediatric neuro-oncology cases that had surgery in this facility from September 2015 till December 2019. We would like to discuss our experience with regard to the clear benefits and the challenges in using such technology to aid in the surgery. The challenges include the physical setting up the paediatric case preoperatively, the preparation and performing the intraoperative scan, the interpretation of intraoperative images and making a decision and the utilisation of the new MRI data set to assist in the navigation to locate the residue safely. Also discuss the utility of the intraoperative images in the decision of subsequent adjuvant management. The use of iMRI also has other technical challenges such as ensuring the perimeter around the patient is free of ferromagnetic material, the process of transfer of the patient to the scanner and as a consequence increased duration of the surgery. CONCLUSION: Many elements in the use of iMRI has a learning curve and it improves with exposure and experience. In some areas only a high level of vigilance and SOP (Standard operating procedure) is required to minimize mishaps. Currently, the iMRI gives the best means of determining extent of resection before concluding the surgery.

Vaccination Knowledge

Abstract Background Immunisation programs are still facing substantial challenges in achieving target coverage rates. This has been attributed to the growing negative individual vaccination attitudes and behaviours. Most of the current studies assessing vaccination knowledge, attitude and beliefs targets adults. However, young people represent future parents and health care professionals. The objective of this study was to investigate vaccination knowledge attitudes and behaviours among university medical and non-medical students in Europe. Methods We performed a cross-sectional online survey between April and July 2018. The study participants were students attending different faculties at the University of Antwerp, Belgium and the University of Pisa, Italy. We described sample characteristics. The effect of risk factors was tested with univariate and multivariate logistic regressions. Results A total of 2079 participants completed the survey including 873 medical students and 1206 from other faculties. The average of vaccination knowledge, attitudes, and confidence was respectively 5.51 (SD: 1.41), 4.66 (SD: 0.14) and 5.28 (SD: 0.57) on the 6-points scale. Our respondents demonstrated a high level of awareness with respect to their vaccination history. In total, 67.7% (n = 1407) reported to have received at least one vaccine in the previous five years; only 6.0% (n = 35) did not receive any vaccine in the previous 10 years. According to logistic regression analysis Italian students had significantly higher knowledge, attitude and confidence scores than Belgium respondents. Students of medicine scored significantly higher compared to non-medical students. Conclusions In order to reduce the gaps in vaccinations knowledge between non-medical and medical students we should plan educational interventions. In this way the number of future sceptical parents could be decreased. Further studies are required to explain the differences between countries. Key messages Young adults are the parents and the health care professionals of the future, for this reason their vaccination knowledge attitudes and behaviours should be carefully monitored. European non-medical students have lower vaccinations knowledge, attitudes and confidence compared with medical student. In order to fill these gaps, we should plan educational interventions.

The smoky mouse, Pseudomys fumeus, is an endangered rodent for which ecological information is lacking across much of its range. This paper provides the first detailed study of the local diet and habitat preference of P. fumeus since 1980, conducted on the recently discovered Nullica population in New South Wales. Diet and trap-revealed movements were examined in conjunction with 18 characteristics of habitat to determine the factors influencing habitat choice. Multiple logistic regression of habitat variables and capture locations revealed a floristically determined preference for heath habitat characterised by Epacris impressa, Monotoca scoparia, Leptospermum trinervium, Xanthorrhoea spp. and a variety of legumes. Hypogeal fungi and seeds were the most common food items in the diet of P. fumeus. Fungi were most abundant in winter diet, while seeds and fruit became dominant in late spring and summer. The spring and summer preference for ridge-top heath habitats observed in this study is probably the result of this dietary preference. Resident females constituted 71% of the population in early spring. However, there was a severe decline in numbers of female mice during early spring, and resident males also disappeared from the population. Causes of the decline were unclear. Five of eleven males captured during this study were transient, while no transient females were caught. The sudden decline in the study population, combined with the patchy distribution of suitable habitat and high level of male transience, suggests that P. fumeus form a metapopulation in the Nullica region.

The response of Festuca hallii (Vassey) Piper to time of burning was examined on the Festuca–Stipa grasslands of the Aspen Parklands at the University of Alberta Ranch located 150 km southeast of Edmonton, Alberta. Two defoliation treatments (burning and mowing) were examined on five dates in 1978 (8 April, 27 April, 1 June, 31 July, and 18 October), corresponding to different phenological stages of F. hallii. Burning and mowing reduced the standing crop of F. hallii produced in the first growing season after treatment, but tiller densities increased. Defoliation in early spring (8 April) had little effect on the standing crop; apparently the increase in tiller density compensated for the reduction in tiller length. Inflorescence density also increased following burning or mowing from 8 April to 1 June. Soil temperature (3 cm deep) on previously burned or mown sites was greater than on the control the year after treatment. Festuca hallii tolerates single burns at any time of the year, but early spring fires have the greatest benefits by increased tillering and standing crop. Key words: standing crop, tiller number, leaf length, litter, defoliation, mowing.

Field experiments were conducted in 1987 and 1988 to study the effect of lamb’s-quarters (Chenopodium album L.) interference on broccoli (Brassica oleracea L. var. botrytis ’Emperor’) growth and yield. Broccoli growth was initially affected by weed interference at 28–36 d after seeding. Generally, the negative effect of weed interference on broccoli growth increased with increasing weed density and time after seeding. Interference by 15 lamb’s-quarters plants m−2 reduced the biomass of broccoli plants by 71–73% compared to the weed-free control at 57–58 d after seeding. Weed density-crop yield relationship curves showed that one lamb’s-quarters plant m−2 decreased total yield by 18–20% and marketable yield by 22–37%. Lamb’s-quarters reduced the total yield per plot by decreasing the average head weight of broccoli. The number of heads per plot was not affected. Weed interference also reduced the weight of heads classified as marketable (> 10 cm across). However, in 1987 more heads failed to reach a marketable size which resulted in a much smaller marketable yield than in 1988.Key words: Brassica oleracea var. botrytis, broccoli, Chenopodium album L., weed density, weed interference, cole crop

Improper practices, poor attitudes and lack of knowledge by food handlers are contributing factors for the spread of foodborne diseases. Food safety knowledge is an important factor in improving food safety practices and subsequently food safety attitude. This study is aimed at exploring the food safety knowledge, practice and attitude of FUNAAB students. A self completed questionnaire was answered by randomly selected 270 students from each of the nine (9) colleges in the university and analyzed using SPSS software. The study revealed that almost all of the students had a high level of food safety awareness but the knowledge was not to large extent translated into practice. Majority of the students also had good food safety attitudes as many of them are willing to change their food handling behav-iour when they know they are incorrect (94.8%). The study further revealed similar level of food safety knowledge between the male and female. Despite the level of students’ knowledge, their choice of eating place on campus was determined by the price of the food. This study therefore concluded that good knowledge of food safety does not determine students’ safe handling practices and choice of eating place.Keywords: Food safety
