As now constituted, the human tumor cloning assay performedin Petri dishes has several limitations including: (a) not all patients' tumors form colonies in the assay; (b) the plating efficiencies (number of colonies formed/numberof cells plated) are low; and (c) a large number of tumor cells are required to perform drug sensitivity testing. In this study the use of capillary tubes, as vessels i...

The study aimed at controlling the mycelial growth and germination of Mycosphaerella fijiensis in Petri dish by using three plant defense stimulators. Approximately, 2 mL each stimulator (Vacciplant®, Callel® calliete®) were added to different M. culture media. results obtained show that Vacciplant® promote vitro contrary calliete® which inhibits it. Indeed, it causes total mortality (100%) con...

Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...

Skin window preparations are made on the anterior aspect of the forearm, using a method already described in detail (Ghosh et al, 1973). After careful cleaning of the skin with soap and spirit, the epidermis is scraped away over a small area with a sterile scalpel blade until exudation is noted. Loose squames are wiped away and a sterile coverslip is applied. For this purpose a circular coversl...

Nematode species, strains, or isolates of the entomopathogenic family Steinernematidae differ in their ability to infect insects at low temperatures. Some steinernematid isolates from British Columbia, probably a new species, killedGalleria mellonella larvae at 7°C. In laboratory experiments, these nematode isolates (isolates 69, 76, 99, 102, or D) were applied to petri dishes at concentrations...

Introduction: Mechanical stimulation of human mesenchymal stem cells has demonstrated changes in many cell behaviours such as adhesion, migration, growth and differentiation through mechanotransductive pathways. These include experiments on effect of nanotopography 1, shear stress, stiffness of extracellular matrix 2, strain, stress and acoustic wave energy 3 on cells. In this research we wer...
