Most recently, Maria earned her Masters of Science in Organizational and Professional Communications also from Regis College. As a Brockton resident for over 15 years, Maria is delighted to be part of the RAR team and to bring books home to more children in the City of Champions- Brockton.
Books have been an essential element in her life. Some of the most influential authors from her childhood include Rafael Pombo, Jules Verne, Fyodor Dostoyevsky, Jose Saramago, and Garcia Marquez. Her passion for reading led her to earn a BA in Education & Literature in Colombia (and to use it to teach in Elementary Schools for 8 years!), and a Dual Language Certificate at UMass Boston.
In the two years that followed, Ukrainians, Russians, Gypsies and people of all nationalities were murdered in Babi Yar. The belief that Babi Yar is an exclusively Jewish grave is wrong... It is an international grave. Nobody will ever determine how many and what nationalities are buried there, because 90% of the corpses were burned, their ashes were scattered in ravines and fields.[47]
Before the Nazis retreated from Kyiv ahead of the Soviet offensive of 1944, they were ordered by Wilhelm Koppe to conceal their atrocities in the East. Paul Blobel, who had been in control of the mass murders in Babi Yar two years earlier, supervised the Sonderaktion 1005 in eliminating its traces. The Aktion was carried out earlier in all extermination camps. The bodies were exhumed, burned and the ashes scattered over farmland in the vicinity.[52][53] Several hundred prisoners of war from the Syrets concentration camp were forced to build funeral pyres out of Jewish gravestones and exhume the bodies for cremation.[54]
Two additional perpetrators were given prison sentences at the Nuremberg Trials.[22] In 1967, 11 men were charged for participating in the massacre in a German court in Darmstadt. After a 14 month trial, seven were convicted and sentenced to prison terms ranging between four and fifteen years.[58] In 1971, three more former German police officials were put on trial in Regensburg.[59] The vast majority of the perpetrators were never tried for their roles in the massacre.[60]
In the spring of 1961, Babi Yar was the site of a massive mudslide. An earthen dam in the ravine was used to hold loam pulp which had been pumped from the local brick factories without sufficient drainage over the course of ten years. The dam collapsed after it was hit by a heavy rainstorm, resulting in a mudslide that swept away the low-lying Kurenivka neighborhood and several other areas. The death toll was estimated to be between 1,500 and 2,000 people.[65]
CIMP as a Marker of Gene Methylation. As stated previously, a genetic basis for cancer has been established with the assumption that the age (and mutagen exposure) related accumulation of somatic mutations accounts for the increased incidence of cancer with age (Ames et al., 1993). The actual rate of mutation accumulation in aged tissues is more uncertain, with some investigators finding lower than expected mutation rates (Warner and Price, 1989; Bohr and Anson, 1995), possibly reflecting the presence of additional mechanisms for activation and/or inactivation of genes important in the carcinogenesis process. In the past few years, there has been renewed interest in epigenetic mechanisms in carcinogenesis (Jones, 1996; Baylin et al., 1998). Epigenetics refers to the study of changes in gene expression that can be mitotically inherited, without associated changes in the coding sequence of the affected genes. Aging and transformed cells show profound changes in gene expression, many of which cannot be accounted for genetically (Sager, 1997). Methylation of DNA within promoter-associated CpG islands can be a powerful molecular mechanism for gene silencing (Razin and Riggs, 1980; Adams and Burdon, 1982).
Folate, MTHFR, and Gene Methylation. An increasing epidemiologic body of evidence from case-control (Ferraroni et al., 1994) and cohort studies (Giovannucci et al., 1995, 1998; Glynn et al., 1996) supports the important role of folate in reducing the risk of colorectal cancer. Another study (Ma et al., 1997), which did not have comprehensive dietary data, showed an inverse association between plasma folate and risk of colon cancer. Folate intake and blood levels have also been consistently associated with lower risk of colon adenomas (Giovannucci et al., 1993; Tseng et al., 1996). Recent results indicate that increased consumption of folic acid from supplements, after a period of 15 or more years, may decrease the risk of colon cancer by about 75% (Giovannucci et al., 1998). Giovannucci et al. (1993) have proposed that the increased risk associated with low folate levels is related to intracellular methylation defects. Additionally, these investigators proposed that alcohol consumption increases the risk of colorectal neoplasia by acting as a folate antagonist; this hypothesis is based on data demonstrating the modifying effect of folate and methionine on the alcohol and colorectal neoplasia relationship (Giovannucci et al., 1993, 1995; Ma et al., 1997).
In the future, approaching disease clusters will require collection of disease rates in registries because if we don't know the baseline level of any disease, it is impossible to know if the reported cluster is a statistical aberration or not. We also need better tracking of exposures, because the more accurately you document people's precise level of exposures, the more accurately you can calibrate risks. The Centers for Disease Control and Prevention (CDC) has just started to release a report on a series of chemicals in the American people. We will continue adding 25 chemicals each year until we have a total of 100 in four years. We are moving beyond the traditional two-by-two table investigations where we look at exposed, unexposed, disease, no disease. The era of looking at exposures and not looking at the genetic makeup of the individual in our epidemic studies is over. Trying to tease out nature versus nurture is a recipe for disaster. We need to be able to look at both of these at the same time.
In nonmalignant bronchial epithelium 218 foci (195 of histologically normal or slightly abnormal epithelium and 23 of dysplastic epithelium) were studied from 19 surgically resected lobectomy specimens (Park et al., 1999). Thirteen (68%) of the nineteen specimens had at least one focus of bronchial epithelium with molecular changes. At least one molecular abnormality was detected in 32% of the 195 histologically normal or slightly abnormal foci and in 52% of the 23 dysplastic foci. Extrapolating from a two-dimensional analysis, we estimate that most clonal patches contain approximately 90,000 cells. Although, in a given individual, tumors appeared homogeneous with respect to molecular changes, the clonally altered patches of mildly abnormal epithelium were heterogeneous. Our findings indicate that multiple small clonal or subclonal patches containing molecular abnormalities are present in normal or slightly abnormal bronchial epithelium of patients with lung cancer. In detailed studies of bronchial epithelium and bronchial biopsies from current or former smokers without lung cancer, we also find thousands of clonal patches showing allele loss in histologically normal-appearing respiratory epithelium. In fact, these patches can be detected more than 30 years after cessation of cigarette smoking. This would suggest the potential for damaged stem cells to repopulate.
In the United States, cancer is the leading cause of death due to disease among individuals between the ages of 1 and 20. The annual incidence rate is 15/ 100,000, which translates into a cumulative risk of cancer equivalent to 1 in 300 by the age of 20 years. The types of malignancies in children and adolescents differ from adults and include (annual rate per million and proportion): leukemia (37, 24.8%); lymphoma (24, 16.1%); brain and central nervous system (CNS) (25, 16.8%); neuroblastomoa (7, 4.7%); retinoblastoma (3, 2.0%); kidney, predominantly Wilms' tumor (6, 4.0%); liver, predominaently hepatoblastoma (2, 1.3%); bone, primarily osteoscarcoma; and Ewing's sarcoma (9, 6.0%); soft tissue, predominaently rhabdomyosarcoma (11, 7.4%); germ cell (10, 6.7%); and others (15, 10.0%).
The survival rate for childhood and adolescent cancer has increased dramatically during the past three decades. Currently, more than 70% of individuals diagnosed with cancer before age 15 will survive five or more years from diagnosis, with the majority being cured of their original malignancy. With these improvements in treatment and survival, it is estimated that approximately 1 in every 900 individuals in the United States between the age of 15 and 45 is now a survivor of childhood cancer. These survivors are, however, at increased risk for long-term complications of their initial cancer and subsequent therapy. Late sequelae of childhood cancer can include an increased risk of second and subsequent malignancies, as well as serious organ dysfunction and psychosocial effects. As more patients survive and the length of follow-up grows, patterns of second and subsequent malignancies are being identified in survivors, including increased rates of breast cancer, thyroid malignancies, CNS tumors, and leukemia. 59ce067264
