Detection of salmonellae was performed on egg shells and egg contents of duck eggs. Five hundred and sixty-four tested samples were came from 1,128 eggs, 2 eggs in each sample. Eggs were collected from retail markets in Bangkok, Chon Buri, Chachoengsao, Lop Buri, Ang Thong and Nakhon Ratchasima provinces during January through June 1992. The percentage of salmonellae contamination on the egg sh...

introduction: proteins are vital substances for health since they provide nitrogen, amino acids and the energy required for normal body performance. however, the applications of proteins are limited due to their certain properties, such as their low solubility. the enzymatic hydrolysis of proteins is an extensively used approach to produce bioactive peptides and promote the chemical, functional...

Pumpkin (Cucurbita maxima) belongs to the Cucurbitaceae family. Its seeds contain large quantities of proteins (35%) and unsaturated fatty acids (50%, mainly linoleic acid and oleic acid), tocopherols, and phytosterols. The seeds are usually consumed toasted as an appetiser, in salads, or as an additive to bread. The flour obtained by grinding the seeds is mixed with water and used as bait by f...

Phyllosphere microbiota play a crucial role in plant-environment interactions and their microbial community and function are influenced by biotic and abiotic factors. However, there is little research on how pathogens affect the microbial community of phyllosphere fungi. In this study, we collected 16 pumpkin (Cucurbita moschata) leaf samples which exhibited powdery mildew disease, with a sever...

The relative number of copies of pumpkin DNA sequences which are complementary to high molecular weight ribosomal RNA (HMW rRNA), 5S and 4S RNA was found, by DNA-RNA hybridization experiments, to be approximately 1:1.2:2.5. At saturation, the levels of hybridization obtained with these RNAs were 2.4%, 0.029% and 0.044%, respectively. Based upon a haploid genomic DNA content of 4.9 x 10^' dalton...

Abiotic stresses cause extensive losses to agricultural production worldwide. In this study, the effects of various abiotic stresses on the upregulation of methylglyoxal levels and glyoxalase I activities in pumpkin seedlings (Cucurbita maxima Duch.) were investigated. Most of the stresses caused significant increases in methylglyoxal level and glyoxalase I activity, white light causing the hig...

Introduction: In traditional medicine, pumpkin seeds are prescribed and used commonly as energetic and sexual enhancer substances. This study was planned and carried out in order to fill the gap caused by the lack of sufficient scientific evidence on the effect of this substance on oogenesis and hormone-pituitary-ovarian axis. Revealing the effect of hydro-alcoholic extract of pumpkin seeds on ...

The black-rot fungus, Myeosphaerella melonis (Pass.) Chiu and J. C. Walker, was first reported in France in 1891 on leaves of a Chinese variety of cucumber {CueUQyiis sativus L.) (¡^i) .^ It was recorded the next year from Delaware on vines of watermelon {Gitrullus vulgaris Sehr ad.), squash {Cucúrbita spp.), pumpkin {Cucúrbita pepo L.), muskmelon {Cucumis meló L.), and cucumber {3). Grossenbac...

The involvement of the ascorbate (AsA) system in the response of pumpkin (Cucurbita pepo L.) roots to aluminium stress was studied. The treatment of 5-day-old pumpkin seedlings with 50 microM aluminium sulphate resulted in approximately 60% inhibition of root growth within 48-60 h of treatment, while aluminium accumulated in the roots reaching a maximum within 48h. During the same period, the h...
