Nonfatal Strangulation: More Than Meets the Eye.

Nonfatal strangulation is a relatively newly recognized mechanism of injury that may not be taken seriously because of lack of physical injuries that many times accompany it. This comparison case series supports the importance of considering not only visually detected injuries but also symptoms the patient may be experiencing when determining diagnostics necessary to guide a treatment plan. A visually detectable injury is dependent on multiple factors.

Characterization of a Vibrio fischeri aminopeptidase and evidence for its influence on an early stage of squid colonization.

Vibrio fischeri cells are the sole colonists of a specialized light organ in the mantle cavity of the sepiolid squid Euprymna scolopes. The process begins when the bacteria aggregate in mucus secretions outside the light organ. The cells eventually leave the aggregate, enter the light organ, and encounter a rich supply of peptides.

Umbilical cord stem cell transplantation.

Objectives: To discuss the history, current state, and future directions of umbilical cord blood (UCB) transplantation as it relates to the emerging field of cellular therapies.

Data Sources: Research studies, articles, and personal experiences.

Conclusion: Transplantation using hematopoietic stem cells from UCB is a life-saving option for patients with select oncologic and immunologic diseases, bone marrow failure, hemoglobinopathies, and inborn errors of metabolism.

Determination of total chromium in environmental water samples.

It is often desirable to quantify both dissolved Cr(VI) and total Cr in samples accurately. Various protocols are now being utilized to quantify the amount of total chromium in natural waters and each of these has possible interferences. This study describes the shortcomings of each method when particulate iron is present in a water sample, and a more rigorous digestion protocol is tested.

Comparison of method 1623 and cell culture-PCR for detection of Cryptosporidium spp. in source waters.

Analysis of Cryptosporidium occurrence in six watersheds by method 1623 and the integrated cell culture-PCR (CC-PCR) technique provided an opportunity to evaluate these two methods. The average recovery efficiencies were 58.5% for the CC-PCR technique and 72% for method 1623, but the values were not significantly different (P = 0.
