The use of sequential staining for detection of heterogeneous intracellular response of individual Jurkat cells to lysophosphatidylcholine.

Living cells are known to exhibit great morphological, functional, spatial and temporal heterogeneity. Hence, the study of cells in a bulk, whether this bulk is homogenous or heterogeneous, does not provide sufficiently detailed or interpretable results. An advantageous approach would rather be a comprehensive study of cell biological activity in single isolated living cells.

A three-year programme in oral diagnosis and treatment planning. A model using an interdisciplinary teaching team.

Diagnosis and treatment planning are considered to be the basis for successful clinical dentistry, however, these skills are difficult to teach and evaluate. At the Department of Diagnosis and Treatment Planning, Tel Aviv University Dental School, a 3-year teaching programme has been developed. The goals of the programme are to teach a systematic pattern of data collection from history, clinical examination, imaging modalities and models, and to use this data to identify the patient's problems and to arrive at a final diagnosis, to develop a treatment plan, taking into account all relevant information, and to consult experts when needed, to train in case presentation, and to deal with peer response.

Metastatic tumors to the jawbones: analysis of 390 cases.

A review of the English language literature revealed 390 well-documented cases of metastatic lesions to the jawbones. Most metastatic lesions were diagnosed in patients in their fifth to seventh decade. The primary site differed between the genders: for women, it was the breast followed by the adrenal, colo-rectum, female genital organs and thyroid; for men, it was the lung, followed by the prostate, kidney, bone and adrenal.

Metastatic tumors to postextraction sites.

Review of the literature revealed 55 cases where tooth extraction preceded the discovery of metastases. The lung and breast were the most common sources of the metastasis, and the mandibular premolar area was the most common site. A soft tissue mass extruding from a recent extraction wound, and accompanied by pain, were the main symptoms in most patients.
