As the nature of the causative agent of yellow fever was unknown, it was necessary at the beginning of these experiments to formulate a spedal method of cultivation. The methods employed have been similar to those recommended 1 for the cultivation of Leptospira icterohcemorrhagice (Inada and Ido). Instead of the serum and citrate plasma of the rabbit or other animal, serum and plasma from nonim...

Megakaryocytes and their precursor cells were sustained in mouse bone marrow suspension cultures for over 4-6 wk. Megakaryocyte precursor cells were detected by their capacity to form colonies of megakaryocytes in semisolid agar cultures. Colony formation was dependent on the presence of medium conditioned by a myelomonocytic leukemic cell line (WEHI-3CM). Megakaryocytes from the liquid and sem...

Resveratrol (RSV) is well known for its anti-oxidant and anti-aging properties. However, resveratrol is insoluble in water and has stability issues. Recently, efforts were placed to prepare a resveratrol-based advanced anti-aging topical product but it contains harsh organic solvents and oils that could be harmful to the human body and the environment. Hence, we propose the use of a multifuncti...

The effect of NaHCO2 on the growth of Neisseria gonorrhoeae cultures was studied in a liquid and a semisolid growth medium. With a broth culture, NaHCO3 (0.009 M) greatly reduced the lag phase and also increased the total growth. The same concentration of bicarbonate supported rapid growth when added to the semisolid medium if the plates were individually incubated in sealed plastic bags. In a ...

New Mg-3Zn-2Ca magnesium alloy was prepared using different processing techniques: gravity casting as well as squeeze casting in liquid and semisolid states. Materials were further thermally treated; thermal treatment of the gravity cast alloy was additionally combined with the equal channel angular pressing (ECAP). Alloy processed by the squeeze casting in liquid as well as in semisolid state ...
