Application of X-ray absorption fine structure method for the quantitative analysis of hexavalent chromium in chromate conversion coating and plastic.

The X-ray absorption fine structure method was applied for the quantitative analysis of hexavalent Cr in electronic products. The pre-edge peak intensity of the Cr K-edge increased according to the hexavalent Cr amount, and the hexavalent Cr ratio was calculated quantitatively by using the intensity. By combining with inductively coupled plasma atomic emission spectroscopy measurement results that gave the total Cr amount, the absolute amount of hexavalent Cr in chromate conversion coating and plastic samples could be evaluated.

In vitro cultivation and antibiotic susceptibility of a Cytophaga-like intracellular symbiote isolated from the tick Ixodes scapularis.

A Cytophaga-like organism (CLO), isolated from the tick Ixodes scapularis (IsCLO), was adapted to growth in insect cell lines and its antibiotic sensitivity was tested. IsCLO were introduced to four insect cell lines, and their growth was measured by quantitative polymerase chain reaction. IsCLO propagated well in a mosquito cell line, AeAl-2, and caused cytopathic effects in host cells.

Successful reimplantation of total femoral prosthesis after deep infection.

A 16-year-old boy developed a deep infection with methicillin-resistant Staphylococcus aureus 6 months after total femoral replacement including knee and hip joints. The deep infection was eradicated by the use of débridement with continuous irrigation and removal of all prosthetic components followed by insertion of an antibiotic-impregnated cement spacer. Six weeks later, the total femoral prosthesis could be successfully reimplanted with both acetabular and tibial components.
