Short tracts of DNA sequence that are used as landmarks in GENOME mapping. In most instances, 200 to 500 base pairs of sequence define a Sequence Tagged Site (STS) that is operationally unique in the human genome (i.e., can be specifically detected by the polymerase chain reaction in the presence of all other genomic sequences). The overwhelming advantage of STSs over mapping landmarks defined in other ways is that the means of testing for the presence of a particular STS can be completely described as information in a database.

Interacting populations affecting proliferation of leukemic cells in culture. (2/236)

Peripheral blood cells from three patients with acute leukemic have been studied using a suspension culture method previously described.1 Cytogenetic studies in two of the patients permitted the identification of the proliferating cells in the cultures as being derived from a leukemic population. Cell separation studies using velocity sedimentation supported the concept that growth of the leukemic cells in culture is dependent on an interaction between two populations of leukemic cells.  (+info)

De novo appearance of the ph-1 chromosome in a previously monosomic bone marrow (45,XX,-6): conversion of a myeloproliferative disorder to acute myelogenous leukemia. (3/236)

Bone marrow examination of a patient with a myeloproliferative disorder revealed monosomy for chromosome No. 6 (45,XX,-6). Two months later, during blastic crisis, reinvestigation of the bone marrow showed the presence of the Ph-1 chromosome in the previously aneuploid cell line (45,XX,-6,-22,+Ph-1). This case differs from those previously published in that the Ph-1 chromosome appeared de novo during the development of frank acute myelogenous leukemia.  (+info)

Removal of abnormal clone of leukaemic cells by splenectomy. (4/236)

A patient with chronic myelocytic leukaemia positive for the Philadelphia (Ph-1) chromosome underwent splenectomy in the "terminal phase" of his disease. Chromosomal analysis of a marrow aspirate obtained during the operation showed nothing abnormal. Material from the spleen, however, showed the absence of a C chromosome and the presence of a "marker" chromosome in all metaphases examined. The patient did well for almost three years after splenectomy, and serial cytogenetic studies of marrow specimens showed the Ph-1 chromosome to be the only significant abnormality. Six months before death from recurrent blastic transformation aneuploidy was found in a marrow specimen. Subsequently additional abnormalities, including cells with two Ph-1 chromosomes, were detected. The karyotypic abnormalities found in the splenic specimen, however, never recurred.  (+info)

Antibody responses to leukemia-associated antigens during immunotherapy of chronic myelocytic leukemia. (5/236)

We have studied immunologic reactivity to leukemia-associated antigens in patients with chronic myelocytic leukemia (CML) treated with chemotherapy and adjunctive immunotherapy. All patients were immunologically competent as measured by skin test reactivity to dinitrochlorobenzene. Immunotherapy consisted of allogeneic irradiated leukemic myeloblasts injected intradermally, with BCG vaccine (Research Foundation, Chicago, Ill.) given by multiple puncture at the same site. 10(9) cells plus BCG were given weekly for 4 wk, and 10(8) cells plus BCG were given at monthly intervals thereafter. Eight patients judged clinically to be in the stable phase of their disease developed circulating antibody against the immunizing blast cells demonstrable by cytotoxicity and immunofluorescence assays. The antibody also showed reactivity against a panel of myeloblasts (12 paients) but not against the corresponding remission lymphocytes (five patients) or normal lymphocytes (20 donors). In two cases the antibody showed reactivity against the patient's own leukemic blasts. Seven of these eight patients have maintained a steady clinical course ranging from 20 to 40 mo, while one entered the blastic phase and died. Six patients were judged to be in the aggressive phase of CML because of progressive leukocytosis and splenomegaly or increasing myeloblastosis; five died an average of 16 mo after diagnosis. Humoral antibodies were not detected in these patients after repeated courses of BCG and allogeneic leukemic cells. We conclude that specific active immunotherapy of patients with CML can abet the production of humoral antibody against blast cell antigens and that this response may be impaired during the aggressive phase of the disease.  (+info)

Chronic myelogenous leukemia presenting in the blastic phase and its association with a 45 XO Ph1 karyotype. (6/236)

A 58-yr-old male patient presented in the blastic phase of chronic myelogenous leukemia (CML). Cytogenetic studies revealed a 45 XO Ph1 chromosome pattern in bone marrow cells during a short remission and again in the blastic phase of the disease. The patient expired 8 mo following diagnosis. The blastic phase of CML can stimulate acute myelogenous leukemia (AML) clinically and hematologically; CML can be differentiated by the presence of the Ph1 chromosome and the stigmata of CML. Absence of the Y chromosome from the bone marrow in CML is a recently described finding. Previous reports indicating the prevention of the blastic phase in patients with this karyotype could not be confirmed by our or other recently reported cases.  (+info)

Discordant patterns of chromosome changes and myeloblast proliferation during the terminal phase of chronic myeloid leukemia. (7/236)

A patient with Ph1 positive chronic myeloid leukemia (CML) developed blastic transformation which by morphologic criteria appeared to be localized to the lymphatic system. Chromosome analysis at this time, however, revealed new chromosomal abnormalities in addition to the existing Ph1 in all tissues studied (lymph node, blood, and bone marrow) consisting primarily of extra chromosome numbers 19 and 9 and a second Ph1. Therapy resulted in clinical remission with significant decrease in the aneuploid cell lines. However, these reappeared with recurrence of the blast crisis. Colony formation in semisolid culture of blood and marrow cells at the time of initial blast crisis yielded growth patterns characteristic of CML. On recurrence of the blast crisis after therapy, growth patterns were characteristic of CML in blast crisis or acute myeloblastic leukemia even though blood and marrow still showed relatively low levels of myeloblasts and promyelocytes. Possible explanations are discussed for the disparity in distribution between morphologic and chromosomal abnormalities in this patient.  (+info)

Prognostic value of chromosomal findings in Ph1-positive chronic myelocytic leukemia. (8/236)

Chromosome examinations were performed on bone marrows from 88 patients with Ph1-positive chronic myelocytic leukemia (CML). As a group, Ph1-positive CML patients with some cytogenetically normal cells in the marrow survived much longer than those whithout such cells in their marrow. The survival for patients whose first bone marrow exhibited only metaphases with a Ph1 and other karyotypic abnormalities was significantly shorter than that for patients whose marrow exhibited only metaphases with a Ph1 and an otherwise normal karyotype or patients whose marrow contained both categories of cells. The shorter the interval between the diagnosis of CML and the first chromosome examination, the greater the frequency of karyotypically normal cells in the bone marrow. Karyotypic progression in CML was a common phenomenon, whereas a reversion was very rare. On the basis of the findings obtained, the early diagnosis and treatment of CML are indicated, both possibly being helped by the chromosomal findings in the marrow. Furthermore, a combination of the chromosomal data and the marrow cell differential may serve as an important prognostic index in CML.  (+info)

CML progresses gradually. It is often slow growing for many years. Eventually, it may transform itself into acute myelogenous leukemia (AML). This is a more aggressive type of leukemia. It progresses much more rapidly and is more serious.. Cancer occurs when cells in the body become abnormal. They divide without control or order. Leukemia is cancer of the white blood cells and their parent cells. Leukemia cells do not function normally. They cannot do what normal blood cells do. In this case they can not fight infections. This means that the person is more likely to become infected with viruses or bacteria. The cancerous cells also overgrow the bone marrow. This forces other normal components, like platelets out. Platelets are needed to help the blood clot. As a results people with leukemia may bleed more easily.. ...

Most patients will develop mild to moderate adverse events or side effects early in tyrosine kinase inhibitor therapy, and most will resolve spontaneously or can be well-controlled.. Adverse events and side effects can be divided into four grades based on severity. Grade 1 would require no change in tyrosine kinase inhibitor therapy, however, may require specific treatment. Grade 2 would involve withholding therapy until severity decreases, or continuing therapy with treatment if symptoms decrease in severity with monitoring. If a Grade 2 side effect is recurrent, therapy dose reduction should be considered. Grade 3 should involve withholding therapy until severity decreases and then restarting at a lower dose or withholding till symptoms reach a grade 1 level or less and resume prior dosage. If there is no resolution or Grade 3 side effects are recurrent, the tyrosine kinase inhibitor should be changed. Grade 4 events should involve switching tyrosine kinase inhibitor therapy when ...

I continue to find reasons to be hopeful that one day, though probably not within my lifetime, medical researchers will overcome the challenges that thwart efforts to cure or at least contain most cancers, especially the more common ones. |p| My guarded optimism stems from the progress made in devising treatments for several less well-known malignancies. For many patients with cancers like chronic lymphoma, chronic myelocytic leukemia and now multiple myeloma, longevity lies in the ability of science to remain one step ahead of the malignancy by unraveling its genetic and molecular underpinnings and producing treatments tailored to counter them. |p|

Basophils possess membrane bound IgE molecules, and immunological activation leads to a secretory process with cell degranulation and histamine release. Heterologous anti IgE, concanavaline A, and phytohaemagglutinin are potent non-cytotoxic releasing agents. They operate by a mechanism similar to that of immunological activation. Heavy water is not a histamine releasing inducer but it increases histamine release of the cells. We studied the histamine release reaction of leukaemic basophils in 10 patients and found a physiological response such as that previously reported with normal human basophils.. ...
Abstract: Findings from a longitudinal study of language acquisition in a group of autistic children are presented. Six autistic subjects and six children with Down syndrome, matched on age and MLU at the start of the study, were followed over a period of between 12 and 26 months. Language samples were collected in the childrens homes while they interacted with their mothers. Samples of 100 spontaneous child utterances from the transcripts were analyzed using the following measures: MLU, Index of Productive Syntax, lexical diversity, and form class distribution. The results indicate that the majority of these autistic children followed the same general developmental path as the Down syndrome children in this study, and normal children reported in the literature, in the acquisition of grammatical and lexical aspects of language, and confirm previous findings suggesting that autism does not involve a fundamental impairment in formal aspects of language.. A longitudinal study of language ...

A cobalamin-dependent N5-methyltetra-hydrofolate-homocysteine methyltransferase (methyl-transferase) was demonstrated in unfractioned extracts of human normal and leukemia leukocytes. Activity was substantially reduced in the absence of an added cobalamin derivative. Presumably, this residual activity reflects the endogeneous level of holoenzyme. Enzyme activity was notably higher in lymphoid cells than in myeloid cells. Thus, mean specific activities (+/-SD) were: chronic lymphocytic leukemia lymphocytes, 2.15+/-1.16; normal lymphocytes, 0.91+/-0.59; normal mature granulocytes, 0.15+/-0.10; chronic myelocytic leukemia granulocytes, barely detectable activity. Properties of leukocytes enzymes resembled those of methyltransferases previously studied in bacteria and other animal cells. Granulocytes and chronic myelocytic leukemia cells contain a factor or factors that inhibits Escherichia coli enzyme. The data suggest that the prominence of this cobalamin-dependent enzyme in lymphocytes and other ...
Developmental data from 612 patients with Downs syndrome have been collected over a period of 20 years from an outpatient clinic for mentally retarded children. Ss ages ranged from birth through 16 years, all being reared in their homes.. With higher percentages of children with Downs syndrome remaining in the home environment and eventually attending day care programs, questions naturally arise concerning the developmental expectations of such children. To answer some of these questions developmental information was abstracted from the clinical records and subjected to statistical analysis. These data include motor and language development and intellectual growth. Despite the limited sample developmental norms for children with Downs syndrome were established, which should prove useful in clinical evaluation.. ...

It was time for a routine 5 month ultra sound it was in January 2009 and we decided to take our 3 year old to meet his new sibling. It was an experience! He stole the show with his comments and enthusiasm he had everyone in the room laughing. We did not want to know the sex of the baby we loved the surprise. At the end the doctor lightly mentioned that she did not see a stomach bubble and would like to do another ultra sound in a month. Both my husband and I did not think much about this. I mentioned this to friends and they reassured me that if she is looking in a month it must be nothing to worry about. I did no research during this time which is unlike me but I just did not think it was a big deal. The ultra sound day came February 17, 2009 I told my husband not to come that it was nothing and that there was no worries besides I was feeling the baby move and it was very reassuring. In the waiting room I remember getting really excited that they had a 3-D ultra sound machine I really wanted ...

Chronic myelogenous leukemia (CML) is an uncommon type of cancer of the bone marrow - the spongy tissue inside bones where blood cells are made. CML causes an increased number of white blood cells in the blood.. The term chronic in chronic myelogenous leukemia indicates that this cancer tends to progress more slowly than acute forms of leukemia. The term myelogenous (my-uh-LOHJ-uh-nus) in chronic myelogenous leukemia refers to the type of cells affected by this cancer.. Chronic myelogenous leukemia can also be called chronic myeloid leukemia and chronic granulocytic leukemia. It typically affects older adults and rarely occurs in children, though it can occur at any age.. Advances in treatment have contributed to a greatly improved prognosis for people with chronic myelogenous leukemia. Most people will achieve remission and live for many years after diagnosis. ...

The discovery of the Philadelphia chromosome as a hallmark of chronic myelogenous leukemia in 1960 by Peter Nowell provided evidence for a genetic link to cancer. As with most seminal scientific observations, the description of the Philadelphia chromosome posed many more questions than were answered. This Review series includes contributions from individuals who performed critical experiments addressing some of the most important of these questions, reflecting the nearly 50 years of work inspired by Nowells initial finding. The legacy of the Philadelphia chromosome now serves as a paradigm for how basic science discoveries can lead to effective new approaches for the treatment of human disease.
Hi! My name is Qadoshyah and Im the oldest of 11 kids. I live on a ranch in the beautiful country of Northeastern Oklahoma with my family. We are a large household with so many kids that we have various projects going on: We raise goats, pigs, sheep, and rabbits (I raise the rabbits - cute little mini lops) on our 44 acre ranch. Our ranch is also home to bullmastiffs, chickens, guinea hens, ducks, llamas, a donkey, a bottle calf, and several ranch dogs and livestock guardian dogs. The youngest two kids are boy/girl twins born in Feb. 05. The boy happens to have Down syndrome. He is such a blessing to our family :)! Our whole family is also gluten-free, which adds another interesting aspect to our large, active family. We also cook dairy-free & corn-free due to allergies a few kids have. Some of the family is also on the GAPS diet to restore gut health ...

Tasigna is a cancer drug indicated to treat patients suffering from Philadelphia chromosome positive chronic myelogenous leukemia (CML).. At least a dozen studies published in prominent medical journals have suggested a link between Tasigna and arteriosclerosis. In April 2013, the Canadian prescribing information for Tasigna was updated to note a potential risk of arteriosclerosis. An alert issued by Health Canada noted a review of the Novartis global safety database had identified of 277 cases of atherosclerosis reported between January 1, 2005 and January 31, 2017.. While information about arteriosclerosis was added to the Tasignas U.S. label, a public notification was never issued to doctors and patients in this country. ...

The use of tyrosine kinase inhibitor (TKI) therapy has become more common in pediatric patients in the last few years. This trend is likely to continue as more TKIs are approved and the list of conditions for which TKIs have clinical utility expands. Imatinib (Gleevec™) is a tyrosine kinase inhibitor that is specifically indicated for Philadelphia positive chronic myelogenous leukemia (PHÆCML). Dasatinib (Sprycel™) and nilotinib (Tasigna™) are TKIs indicated for CML patients who are no longer benefitting from, or did not tolerate, other treatments including imatinib. OBJECTIVE:The objective of this study was to determine whether there is evidence of growth retardation as an adverse drug experience for TKIs. METHODS:The FDA Adverse Event Reporting System (FAERS) was reviewed for currently posted data from 4th quarter 2012 until 1st quarter 2014 for individuals ≤ 18 years of age. The most recent update of the FAERs data was in October of 2014. These are sponsor, patient and physician reported
The Constitutional Court will hear an application on Thursday for leave to appeal a Western Cape High Court ruling against a damages claim by the mother of a Down syndrome child.
Later that evening, Linda shared with me the difficulties of helping James transition into the school system. She said the teachers and counselors had plenty of experience with children with autism, but little experience with Down Syndrome children. The reason for this is simple and devastating- children with Down Syndrome are simply not being born. In our country, approximately 90% of all prenatal diagnoses of Down Syndrome end in abortion. Many who make this choice say they are being merciful. They believe they are sparing their child from a lifetime of difficulty and a poor quality of life. Quality of life? What does that even mean?. After I returned home, I started thinking about this more and more. What defines an acceptable quality of life? As I contemplated, I couldnt help but picture a happy, smiling boy playing in the sand with his dad, putting on plays in the living room, laughing with his mom, giving me big hugs and kisses, and, most importantly, praying wholeheartedly to his ...
Why, then, does Singer argue that infants born with this condition can justly be killed? Because they are abnormal and do not have good prospects (Rethinking p. 214). This notion of prospects runs like a mantra through Singers discussion of Down syndrome children: the future prospects of life may be so bleak (211), the prospects are clouded (213), and so forth. But what sort of prospects does he have in mind? On p. 213 of Rethinking he lists several activities which a person with Down syndrome will supposedly never be capable of: to play the guitar, to develop an appreciation of science fiction, to learn a foreign language, to chat with us about the latest Woody Allen movie, or to be a respectable athlete, basketballer or tennis player. This list reads like a parody of bourgeois myths of achievement, success, and respectability. To Singer, however, these are legitimate reasons for killing a newborn. After all, if you cant do your own financial planning, why should you be allowed to ...

At first I thought that maybe she didnt see me smile and I figured that once she sat down and glanced over shed start a conversation. As I was thinking this I also realised that I was facebook friends with this woman!!!! Seriously, when I first had Stella my home based development worker gave my name to all of the families who had a child with Down Syndrome, and this woman friended me. She even sent me a message! So I thought for sure once we were siting there, across from one another that she would say something to me. I had already attempted contact and honestly I just felt so deflated that I could not muster up the nerve to put myself out there again ...
