BACKGROUND In order to provide evidence on health impacts of the tobacco industry on cultivators in Vietnam, this study aims to provide comparison between tobacco cultivation related revenue and expenditure in selected areas in rural Vietnam and examine the relationship between tobacco cultivation and self-reported illness in the study population. METHODS Two tobacco farming communes and two ...
BACKGROUND Parthenocarpy, or fruit development in the absence of fertilization, has been genetically engineered in eggplant and in other horticultural species by using the DefH9-iaaM gene. The iaaM gene codes for tryptophan monoxygenase and confers auxin synthesis, while the DefH9 controlling regions drive expression of the gene specifically in the ovules and placenta. A previous greenhouse tri...
BACKGROUND The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utilis and Kluyveromyces marxianus in an enzymatic hydrolysate of the cladode biomass. RESULTS Dilute acid pretreatment and enzyma...
BACKGROUND Yeast-like fungi inhabit soils throughout all climatic zones in a great abundance. While recent estimations predicted a plethora of prokaryotic taxa in one gram of soil, similar data are lacking for fungi, especially yeasts. METHODOLOGY/PRINCIPAL FINDINGS We assessed the diversity of soil yeasts in different forests of central Germany using cultivation-based techniques with subsequ...
Background and purpose: The 50 KDa protein (50 µg) in carboxylic domain of the neurotoxin heavy chain (BoNT/A-Hc) recognizes surface receptors on target neurons and this fragment contains the principle protective antigenic determinants. Recently, this fragment has been used as a recombinant vaccine candidate for botulism. The study aimed to compare the evaluation of BoNT/A-Hc production in fed-...
In the background of rapid expansion of plastic greenhouse vegetable production in China, many environmental risks have emerged in recent years. In this study, the soils with a chronosequence in greenhouse vegetable fields were collected and the soil humic acids (HAs) and fluvic acids (FAs) were extracted and purified. The soil HAs and FAs were found to show inhibition activities against phytop...
در دنیا مناطقی وجود دارند که ساکنین آنها در معرض پرتوهای طبیعی زمینه بالا هستند. این مناطق به high background radiation areas hbras ، معروف می باشند. از جمله این مناطق می توان به گوارا پاری در برزیل ، کرالا در هند ، نواحی از آمریکا و یانگ جیانگ در چین اشاره کرد. در ایران نیز مناطق با پرتودهی زمینه بالا مشاهده شده است . رامسر یکی از این مناطق است .
Standard cultivation fails to grow most microorganisms, whereas in situ cultivation allows for the isolation of comparatively diverse and novel microorganisms. Information on similarities and differences in the physiological properties of isolates obtained from in situ cultivation and standard cultivation is limited. Therefore, we used the arctic sediment samples and compared two culture collec...
