SUMMARY At present research, the antibacterial potency of 4 antiseptic agents formulated in mouthwash products against four gram-positive cocci and 2 gram-negative bacilli isolated from dental plaque and abscess evaluated by five specific in-vitro methods. The bacteriostatic effect of four antiseptic agents is as following relation:CHG > > CPO> CPC > PVP-I. But, The quality and quantity of ba...

Passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. The aim of this study was to investigate the chemical composition of the most active leaf extract of Passiflora caerulea L. grown in Egypt. The ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...

The cosmic microwave background radiation provides unique constraints on cosmological models. In this Letter we present a summary of the spatial properties of the cosmic microwave background radiation based on the full 4 years of COBE DMR observations, as detailed in a set of companion Letters. The anisotropy is consistent with a scale-invariant power law model and Gaussian statistics. With ful...

The cosmic microwave background (CMB) is the oldest discernible light in the Universe. It provides us with a photograph of an infant Universe—the Universe 13.7 billion years ago. But this ancient snapshot has been slightly distorted by intervening matter. As CMB light rays propagated through the Universe to us, they encountered countless lumps of matter that slightly deflected their direction b...
