High incidences of Small Cell Carcinoma & Adenocarcinoma of the lung, Astrocytoma & Glioblastoma Multiforme of the brain and Mesothelioma of the lung were found in those who had a high accumulation of Asbestos in the eyes and upper respiratory system (nose, larynx, trachea, etc.). When measured non-invasively using the Bi-Digital O-Ring Test (BDORT), brain tumors had the highest concentration of Asbestos (0.2 approximately 2.1 mg BDORT units). Relatively high levels of Asbestos (0.2 approximately 0.6 mg BDORT units) were found in: Squamous Cell Carcinoma of the lungs & esophagus, Adenocarcinoma of the larynx & breast, myelogenic leukemia, arteries of these cancers, left ventricle of failing heart, myocardial infarction, some of the narrowed arteries, varicose veins, cataracts, balding heads, hot flashes, Alzheimer's Disease and Autism. A small, round or ellipsoidal area, with diameter of 5 mm or less, was found near the center of every cancer tissue with a higher level of Asbestos (1 approximately 3 mg), As, Zn, Cr and Se, than in the rest of the tumor; this small area may be where the cancer initiated. Among areas of intractable pain with frequent recurrence and gradual worsening, about 0.2 approximately 0.5 mg BDORT units (or higher) of Asbestos were found. The author found that in the Astrocytoma and many other cancer patients, the optimal dose of DHEA produced very significant reductions of cancer cell telomere from over 1400 ng in the brain tumors (and over 900 ng in other cancers) to close to or less than 1 yg (=10(-24) g), with circulatory improvement by reduction of TXB2. Unlike the standard, widely used treatment with DHEA 25 approximately 50 mg daily, which is an overdose; we only gave one optimal dose (1.5 approximately 12.5 mg) and the beneficial effects usually lasted anywhere between 3-6 months, unless inhibiting factors were introduced. In addition, once one optimal dose of DHEA was given, the amount of Asbestos from these tumors decreased very significantly (30 approximately 99% reduction) with marked increase in urine Asbestos. One optimal dose of special Cilantro tablet reduced more Asbestos than DHEA or (+) Qi Gong Energy Stored Paper. In addition, the application of (+) Solar Energy Stored Paper often reduces 70 approximately 99% of the Asbestos, while (+) Qi Gong Energy Stored Paper reduces 50 approximately 99% of the Asbestos.

In the Netherlands, the practice of private freezing and banking of umbilical-cord blood is increasing. In a questionnaire, Dutch midwives and gynaecologists were asked about their attitude towards cord-blood collection if asked to perform this after delivery. The response rate was 35% (125/356) and 71% (71/100), respectively. Two-thirds of those asked responded that they would comply. The most common application of cord blood is in the treatment of (malignant) blood disorders. The use of autologous cord blood is, however, often not the best choice for treating leukaemia in young children and the number of stem cells is often too low in a single-cord blood sample to treat older children and adults. Although frequently suggested in the lay press, there is no proven effect in other indications, such as amyotrophic lateral sclerosis, multiple sclerosis and myocardial infarction. Information on therapeutic applications of cord blood from companies with commercial interests is leading to the exploitation ofpregnantwomen. The government should consider limiting this practice and prohibiting the activities of these companies in the Netherlands pending scientific evidence for their claims.

This contribution bridges the gap from early European contributions via laser micromanipulation to recent work on the use of laser microbeams and optical tweezers in studies of basic aspects of heart infarction. Laser transfection, particularly of plant cells and their chloroplasts, and laser microdissection of chromosomes with subsequent generation of chromosome segment-specific DNA libraries and laser-induced cell fusion are reported. With optical tweezers, microgravity can be simulated in roots of the alga Chara. Surprisingly, microgravity reduces growth. In some plant cells, CW lasers, in principle suited primarily for optical tweezers, can be used as microbeam. Also, it is shown that natural killer cells mount an attack on leukemia cells even in the absence of specificity, just induced by exerting force with optical tweezers. Finally, with the help of a laser microbeam, lesions can be induced to study wound healing after heart infarction. A modification of optical tweezers, the erythrocyte-mediated force application (EMFA) technique can be used to induce calcium waves not only in tissue reconstituted from excitable heart muscle cells but also from nonexcitable fibroblasts.

The development of chromosomal abnormalities (CAs) in the Philadelphia chromosome (Ph)-negative metaphases during imatinib (IM) therapy in patients with newly diagnosed chronic myecloid leukemia (CML) has been reported only anecdotally. We assessed the frequency and significance of this phenomenon among 258 patients with newly diagnosed CML in chronic phase receiving IM. After a median follow-up of 37 months, 21 (9%) patients developed 23 CAs in Ph-negative cells; excluding -Y, this incidence was 5%. Sixteen (70%) of all CAs were observed in 2 or more metaphases. The median time from start of IM to the appearance of CAs was 18 months. The most common CAs were -Y and + 8 in 9 and 3 patients, respectively. CAs were less frequent in young patients (P = .02) and those treated with high-dose IM (P = .03). In all but 3 patients, CAs were transient and disappeared after a median of 5 months. One patient developed acute myeloid leukemia (associated with - 7). At last follow-up, 3 patients died from transplantation-related complications, myocardial infarction, and progressive disease and 2 lost cytogenetic response. CAs occur in Ph-negative cells in a small percentage of patients with newly diagnosed CML treated with IM. In rare instances, these could reflect the emergence of a new malignant clone.

Surveys have shown that the prestige of medical specialities is ordered hierarchically. We investigate whether similar tacit agreement in the medical community also applies to diseases, since such rankings can affect priority settings in medical practice. A cross-sectional survey was performed in three samples of physicians and medical students in Norway in 2002. A questionnaire was sent to 305 senior doctors (response rate, 79%), 500 general practitioners (response rate, 65%) and 490 final-year medical students (response rate, 64%). Outcome measures were ratings on a 1-9 scale of the prestige these respondents believed most health personnel would accord to a sample set of 38 different diseases as well as 23 medical specialities. Both diseases and specialities were clearly and consistently ranked according to prestige. Myocardial infarction, leukaemia and brain tumour were among the highest ranked, and fibromyalgia and anxiety neurosis were among the lowest. Among specialities, neurosurgery and thoracic surgery were accorded the highest rank, and geriatrics and dermatovenerology the lowest. Our interpretation of the data is that diseases and specialities associated with technologically sophisticated, immediate and invasive procedures in vital organs located in the upper parts of the body are given high prestige scores, especially where the typical patient is young or middle-aged. At the other end, low prestige scores are given to diseases and specialities associated with chronic conditions located in the lower parts of the body or having no specific bodily location, with less visible treatment procedures, and with elderly patients.

A number of new compounds bearing two ortho-bromo- and ortho, ortho-dibromophenol moieties linked through a saturated/unsaturated, linear/(poly)cyclic spacer (compounds 1- 9) were prepared as simplified analogues of AMI-5 (eosin), a recently reported inhibitor of both protein arginine and histone lysine methyltransferases (PRMTs and HKMTs). Such compounds were tested against a panel of PRMTs (RmtA, PRMT1, and CARM1) and against human SET7 (a HKMT), using histone and nonhistone proteins as a substrate. They were also screened against HAT and SIRTs, because they are structurally related to some HAT and/or SIRT modulators. From the inhibitory data, some of tested compounds ( 1b, 1c, 4b, 4f, 4j, 4l, 7b, and 7f) were able to inhibit PRMTs, HKMT, HAT, and SIRTs with similar potency, thus behaving as multiple ligands for these epigenetic targets (epi-MLs). When tested on the human leukemia U937 cell line, the epi-MLs induced high apoptosis levels [i.e., 40.7% ( 4l) and 42.6% ( 7b)] and/or massive, dose-dependent cytodifferentiation [i.e., 95.2% ( 1c) and 96.1% ( 4j)], whereas the single-target inhibitors eosin, curcumin, and sirtinol were ineffective or showed a weak effect.

The association of acute myeloid leukemia (AML) and acute myocardial infarction (AMI) is rare. We encountered a 40-year-old female with inferior wall myocardial infarction that occurred simultaneously with the diagnosis of AML. She developed subsequent dural sinus thrombosis during chemotherapy for AML. The screen for thrombophilia revealed that she had hyperhomocysteinemia. In the English literature, only 4 cases have been reported previously. Remission induction was not affected by the occurrence of AMI, although anthracyclines were avoided in all cases. In the absence of conventional risk factors for coronary artery disease, AMI can be related to leukemia per se and the role of homocysteine is worth further investigation.

This study evaluated the efficacy and safety of imatinib in chronic eosinophilic leukaemia (CEL, n = 23) and hypereosinophilic syndrome (HES, n = 13). In CEL with FIP1L1-PDGFRA (n = 16) or various PDGFRB fusion genes (n = 5), complete haematological remission (CHR) was achieved in 95% (20/21) after 3 months. Complete molecular remission (CMR) was seen in 75% (12/16) of cases with FIP1L1-PDGFRA positive CEL by 6 months, and in 87% (13/15) after 12 months. CMR was achieved in three of five PDGFRB fusion positive patients after 3, 9 and 18 months respectively. All patients are currently on imatinib (100 mg; n = 13, 400 mg; n = 8) and no molecular relapse has yet been observed (median 26.7 months; range, 6.9-39.9). Imatinib was less effective in HES and CEL without known molecular aberration (n = 15); CHR was observed in 40% (6/15) of patients, two patients relapsed after 4.8 and 24.5 months. Three patients died due to imatinib-resistant progressive CEL (n = 2) or myocardial infarction (n = 1) unrelated to study treatment. Overall, imatinib was well tolerated with a low incidence of grade III/IV toxicities. These data confirmed the long-term efficacy of imatinib for PDGFR-rearranged CEL patients, and also showed that a minority of HES cases without known molecular aberrations may benefit from imatinib.

Coronary artery disease (CAD) is based on the atherosclerosis of coronary artery and may manifest with myocardial infarction or angina pectoris. Although it is widely accepted that genetic factors are linked to CAD and several disease-related genes have been reported, only a few could be replicated suggesting that there might be some other CAD-related genes. To identify novel susceptibility loci for CAD, we used microsatellite markers in the screening and found six different candidate CAD loci. Subsequent single nucleotide polymorphism (SNP) association studies revealed an association between CAD and megakaryoblastic leukemia factor-1 gene (MKL1). The association with a promoter SNP of MKL1, -184C > T, was found in a Japanese population and the association was replicated in another Japanese population and a Korean population. Functional analysis of the MKL1 promoter SNP suggested that the higher MKL1 expression was associated with CAD. These findings suggest that MKL1 is involved in the pathogenesis of CAD.

Heat shock protein 90 (Hsp90) is a molecular chaperone with many oncogenic client proteins. The small-molecule Hsp90 inhibitor alvespimycin, a geldanamycin derivative, is being developed for various malignancies. This phase 1 study examined the maximum-tolerated dose (MTD), safety and pharmacokinetic/pharmacodynamic profiles of alvespimycin in patients with advanced acute myeloid leukemia (AML). Patients with advanced AML received escalating doses of intravenous alvespimycin (8-32 mg/m(2)), twice weekly, for 2 of 3 weeks. Dose-limiting toxicities (DLTs) were assessed during cycle 1. A total of 24 enrolled patients were evaluable for toxicity. Alvespimycin was well tolerated; the MTD was 24 mg/m(2) twice weekly. Common toxicities included neutropenic fever, fatigue, nausea and diarrhea. Cardiac DLTs occurred at 32 mg/m(2) (elevated troponin and myocardial infarction). Pharmacokinetics revealed linear increases in C(max) and area under the curve (AUC) from 8 to 32 mg/m(2) and minor accumulation upon repeated doses. Pharmacodynamic analyses on day 15 revealed increased apoptosis and Hsp70 levels when compared with baseline within marrow blasts. Antileukemia activity occurred in 3 of 17 evaluable patients (complete remission with incomplete blood count recovery). The twice-weekly administered alvespimycin was well tolerated in patients with advanced AML, showing linear pharmacokinetics, target inhibition and signs of clinical activity. We determined a recommended phase 2 dose of 24 mg/m(2).
