Diabetes mellitus is a metabolic disorder that results in hyperglycemia due to decreased insulin production or inefficient insulin utilization. This disease has been reported in animals, particularly in aged dogs. However, the disorder is much more prevalent in humans. Millions of people across the globe currently have diabetes and incidence rates are predicted to increase dramatically as the p...

Maintenance of garlic (Allium sativum L.) genetic resources has had a long tradition in the Czech Republic. The collection was founded in 1951 and its current holder is the Crop Research Institute, Department of Vegetables and Special Crops in Olomouc. The collection consists of 613 genotypes. The oldest genotype was acquired in 1954. The collection has been evaluated according to the Descripto...

BACKGROUND Organosulfur compounds usually present a reduced stability especially in the presence of oxygen. This research aimed to study the stability and antioxidant potential of the Allium ursinum watery extract. RESULTS The decrease of the antioxidant capacity verifies an exponential relation which may be formally associated to a kinetically pseudomonomolecular process. The exponential reg...

Pogostemon auricularius is an aromatic herb belonging to the family Lamiaceae. Objectives: In the present study we have utilized the Allium cepa root tip meristem model to evaluate the cytotoxic and antimitotic potential of P. auricularius. Methods: The roots of Allium cepa were exposed to different concentrations of the aqueous leaf extracts (0.01%, 0.05%, 0.1% and 0.5%), for four different ti...

Bioactive dietary agents have been shown to regulate multiple cancer hallmark pathways. Epidemiologic studies have linked consumption of Allium vegetables, such as garlic and onions, to decreased incidence of cancer. Diallyl trisulfide (DATS), a bioactive compound derived from Allium vegetables, has been investigated as an anti-cancer and chemopreventive agent. Preclinical studies provide ample...

Cytogenetic effects of different herbicides viz. Atrazine, Avenoxan, Diuron and Quizalofop-P-ethyl (QPE), were evaluated in the root tip meristem cells of Allium cepa. In the Allium root growth test, the effective concentration (EC50) value was determined as approximately 0.5 ppm in the case of Atrazine and Avenoxan and 1.0 ppm in the case of Diuron and QPE herbicides with a control for each co...

Worldly data show the increasing incidence of Mycobacterium tuberculosis (MTB) and particularly of multi-drug resistant tuberculosis (MDR-TB). In developing countries, TB control programmes are overwhelmed by the complexity of treating MDR-TB infected people, as current tools and therapies are inadequate. MDR-TB could become the main form of TB. Risk factors that make South Africa into one of t...

Genetic analysis of onion has been hampered by a lack of portable codominant markers based on the polymerase chain reaction (PCR). The public release of a relatively large set of non-redundant onion expressed sequence tags (ESTs) in 2003 has provided the opportunity to develop such markers for use in Allium research and industry. We have mined this collection for simple sequence repeats (SSRs) ...

ROSS chromosome aberrations or rearrangements have recently G come to occupy an important position in the study of problems of evolution and speciation. Such aberrations are known to occur in many plants and animals. However, the spontaneous occurrence of these aberrations is rather difficult to study, since their frequency is usually very low. In an endeavor to obtain a further understanding o...
