Age, Sex, and Religious Beliefs Impact the Attitude towards Cord Blood Banking.

In this study, a self-administered questionnaire was used to assess opinions about stem cell research and cord blood banking. Three attitudes were examined: willingness to accept cord blood banking, willingness to accept embryonic stem cell research, and religious belief system. A total of 90 Wayne State University students enrolled in the study in response to an invitation posted on a web page for the university. Sex distribution among study participants was 79 females and eight males; three declined to state their sex. Support for cord blood banking was high (> 70%) among students. Students over the age of 25 years of age were more (85%) positive than students 18 to 24 years old (57%). They prefered a public cord blood bank over a private cord blood bank. Atheist/agnostic or spiritual/not religious students (> 90%), Catholic students (78%) and Christian students (58%) support cord blood banking. Age, sex and religion seems influence the student's attitude towards stem cell research and cord blood banking.

Malaria detection in the field of paleopathology: a meta-analysis of the state of the art.

An integrative literature review was conducted to identify the current state of the art regarding malaria research in human remains and to identify novel methods to test for malaria infections in archaeological samples. This review was comprised of two surveys. The first survey established methods used currently to detect malaria in human remains from archaeological contexts. The second survey identified diagnostic approaches in the field of medicine. Techniques in medicine that could have applications with samples from archaeological contexts, such as preserved soft tissue and skeletal remains, are presented.

Technical note: a histological technique for detecting the cryptic preservation of erythrocytes and soft tissue in ancient human skeletonized remains.

Bone samples from a Middle Bronze Age (ca., 1600-1300 BC) site were prepared for histological analysis. Preliminary results suggested that components of bone marrow remained preserved. To verify these findings and optimize the sample preparation procedure, we conducted experiments varying the type of acid used to decalcify the bones for histology preparation, as well as the exposure time to the demineralizing agents and thickness of sections taken from the samples for slide preparation. Subsequent examination of the slides revealed the presence of well-preserved erythrocytes and other cellular structures consistent with bone marrow. Our results demonstrate that the traditional methods used to prepare bone samples for histology may be adjusted to improve the quality of the soft tissue architecture and cellular morphology for histological observation.
