The preservation of archaeological brain remains in a human skeleton,

The preservation of archaeological brain remains in a human skeleton,
The identification of biomass within the cranial cavity of a waterlogged human skeleton inside a fish-tailed wooden coffin from a nineteenth century burial has been confirmed as brain tissue. A comparison is made between the Raman spectra obtained in the current study with those from an Iron Age brain found in an isolated cranium dating from about 500 years BCE, ... إقراء المزيد

The Heslington brain: a challenge for analytical Raman spectroscopy
The survival of brain tissue in archaeological depositional environments is a very unusual occurrence that has generated much discussion and conjecture forensically. Here, we report the Raman spectroscopic analysis of biomaterial found in the cranial cavity of a decapitated skull dating from the Iron Age, some 2500 years ago, from which the presence of degraded protein consistent with it being ... إقراء المزيد

Occurrence of toxic cyanobacteria and microcystin toxin in domestic water storage reservoirs, Egypt

Occurrence of toxic cyanobacteria and microcystin toxin in domestic water storage reservoirs, Egypt
Residents in many developing countries store treated drinking water in tanks or reservoirs because of intermittent and infrequent water supplies. Many studies have focused on bacterial contamination of domestic reservoir waters, the cyanobacterial and algal contamination is largely unexplored. Therefore, the present study investigates toxic cyanobacteria and their microcystin (MC) toxins in some domestic water storage reservoirs in Egypt as ... إقراء المزيد

Breakthrough of Oscillatoria limnetica and microcystin toxins into drinking water treatment plants – examples from the Nile River, Egyp

Breakthrough of Oscillatoria limnetica and microcystin toxins into drinking water treatment plants – examples from the Nile River, Egyp
The presence of cyanobacteria and their toxins (cyanotoxins) in processed drinking water may pose a health risk to humans and animals. The efficiency of conventional drinking water treatment processes (coagulation, flocculation, rapid sand filtration and disinfection) in removing cyanobacteria and cyanotoxins varies across different countries and depends on the composition of cyanobacteria and cyanotoxins prevailing in the water source.
