The colon to look for small amounts of blood in the stool and the rectum store the waste until it is evacuated from that cannot be seen with the naked eye. A sigmoidoscopy is an examination of the cular tube about 6 ft long also known as the large intes- rectum and the lower colon, using a lighted tine. The rectum is the specific name for the last 810 instrument called a sigmoidoscope. Being born in North America or Western Europe patient receives an enema with barium, which is a risk factor.

Evidence that a single replication fork proceeds from early to late replicating domains in the Igh locus in a non-B cell line. CpG sites are concentrated either in repetitive sequences or CpG islands in promoter regions. Dietary folate, vitamins B6 and B12, methionine and choline can critically affect the synthesis of AdoMet [3]. Moreover, methylation of CpG islands normally promotes a highly condensed heterochromatin structure, where active transcription does not occur. Methylation of CpG islands naturally takes place during X chromosome inactivation and imprinting, though the majority of CpG islands remain unmethylated during development and differentiation. Further investigation will be needed to elucidate the signicance of conversion to 5-hydroxymethylcytosine. Therefore, intensive screening of genes that are methylated in human cancers may be a strategy for identication of tumor-related genes that have potential as therapeutic targets. In some instances, genes can be silenced simultaneously due to a process of long-range epigenetic silencing, and the spreading of silencing seems to affect neighboring unmethylated genes through repressive chromatin [24]. Transcription of miR-10b is regulated by the transcription factor Twist, and the downstream targets of miR-10b include homeobox D10. Environmental factors inuence health, and epigenetic proles are known to be responses to environmental signals. Ductal adenocarcinomas of the pancreas frequently develop after chronic damage due to pancreatitis. At least a proportion of peripheral pancreatic ductal epithelia with an inam- 33 matory background may be at the precancerous stage. It has long been known that individual cancers each consist of heterogeneous cell populations. The recently proposed cancer stem cell hypothesis has emphasized that only certain subpopulations, known as cancer stem cells, cancer-initiating cells or tumor-propagating cells, have tumorigenic potential. These cancer-initiating cells are usually resistant to chemotherapy and radiotherapy, leading to treatment failure. Despite the existence of such subpopulations, the cancer stem cell hypothesis continues to generate controversy. Since the PcG complex targets similar sets of genes in embryonic stem cells and cancer cells, much effort should be focused on how epigenetic mechanisms participate in the generation of cancer-initiating cells [20,23]. Such subclassication may yield clues for clarication of distinct mechanisms of carcinogenesis in various organs, and identify possible target molecules for prevention and therapy in patients belonging to specic clusters. For example, progressive accumulation of genetic and epigenetic abnormalities has been best described in colon cancers. Together, the data show that colon cancers can be grouped into three molecularly distinct disease subclasses [95]. Multivariate analysis revealed that our clustering was a predictor of recurrence and was independent of histological grade, macroscopic conguration, vascular involvement or presence of renal vein tumor thrombi. Genetic and epigenetic events appear to accumulate in a complex manner during the developmental stage of individual tumors. Decoding of the results indicated that urine from prostate cancer patients contained shed cancer cells or debris. The promoter methylation pattern in urine generally matched that in the primary tumors. Gastrointestinal endoscopy followed by pathological diagnosis of biopsy specimens is useful for diagnosis of stomach cancers. Endoscopic biopsy is a topical procedure whereby only a small portion of the lesion is removed. Moreover, gastrointestinal endoscopy is neither comfortable nor risk-free for patients, and is associated with frequent morbidity. In general, pancreatic biopsy yields only a small amount of tissue, and in specimens of pancreatic juice the cellular morphology is not well preserved due to degeneration. Our diagnostic criteria may be advantageous for supporting the histological and cytological assessment of such specimens. In the validation cohort, these criteria allowed such discrimination with 96% sensitivity and specicity [107].

From extracts of Lophocereus sp two compounds have been isolated: pylocereine and lophocine a dimeric alkaloid with cytotoxic activity [46, 47]. Cecropia obtusifolia Bertolt Family: Cecropiaceae Common name: The names that are known are "guarumbo", "chancarro", "hormiguillo", "chifln" and "koochlle" among others. Its trunk is straight and presents a cavity where you can find some ants inside it, with branches that grow along this horizontally. Distribution in Mexico: located along the coasts of Tamaulipas and San Luis Potosi to Ta basco on the side of the Gulf of Mexico and Sinaloa to Chiapas Pacific side. Traditionally the dried leaves (15 g) are heated in water (500 mL) and the result is an infusion which is then filtered and taken as "daily water", cold infusion is often consumed in hot weather. It is reported that this plant contains -sitosterol, stigmasterol, 4-ethyl-5-(n-3 valeroil)-6-hexahydrocoumar ins. Conclusion The plant kingdom has been the best source of remedies for curing a variety of disease and pain. This is why medicinal plants have played a key role in the worldwide maintenance of health. Traditional herbal medicine is intimately related to the Mexican popular culture; its use has origins based on ancestral knowledge. Natural products of higher plants are an im portant source of therapeutic agents; therefore, many research groups are currently screen ing the different biological activities of plants. Mexico has an extensive variety of plants; it is the fourth richest country worldwide in this aspect. Some 25 000 species are registered, and it is thought that there are almost 30 000 not yet described. Natural antioxidants that are present in herbs and spices are responsible for inhibiting or preventing the deleterious con sequences of oxidative stress. Spices and herbs contain free radical scavengers like polyphe nols, flavonoids and phenolic compounds, having antioxidant activities, Indeed all these plant studied have several biological effects and they could also be used as a source of natu ral antioxidants. Further pharmacological studies are underway to identify the active con stituents of the plant extracts responsible for the showed activities. As a final comment, compounds in plants are of great importance for the treatment of several chronic and degen erative diseases like diabetes and cancer, among others.

Introduction The natural phenolic compounds have received increasing interest in the last years, since a great amount of them can be found in plants and consumption of vegetables and beverages with a high level of such compounds may reduce the risk of development of several diseases due to their antioxidant power, among other factors. The substan ces that are common to living things and essential to cells maintenance (lipids, proteins, car bohydrates, and nucleic acids) are originated from the primary metabolism. On the other hand, substances originated from several biosynthetic pathways and that are restricted to determined groups of organisms are results of the secondary metabolism [1]. Phenolic com pounds are constituted in one of the biggest and widely distributed groups of secondary metabolites in plants [2]. Most plants phenolic compounds are synthe sized through the phenylpropanoid pathway [4]. The combination of both pathways leads to the formation of flavonoids, the most plentiful group of phenolic compounds in nature [3]. Additionally, through the biosynthetic pathways to the flavonoids synthesis, among the not well elucidated condensation and polymerization phases, the condensed tannins or non-hy drolysable tannins are formed. Hydrolysable tannins are derivatives of gallic acid or hexa hydroxydiphenic acid [5]. Therefore, phenolic compounds have, as a common characteristic, the presence of at least one aromatic ring hydroxyl-substituted [6]. Another characteristic of these substances is that they are presented commonly bound to other molecules, frequently to sugars (glycosyl resi due) and proteins. As a result, phenolic compounds play a role of protection against insects and other animals to the plants. This way, phenolic compounds are essential to the physiology and cellular metabolism. Phenolic compounds can be classified in different ways because they are constituted in a large number of heterogeneous structures that range from simple molecules to highly poly merized compounds. According to their carbon chain, phenolic compounds can be divided into 16 major classes [9]. This classification is useful from the nutritional view point, to the extent that the metabolic fate in the gastrointestinal tract and the physiological effects of each group will depend largely on their solubility characteristics. Insoluble phe nolic compounds are not digested and may be partially or fully recovered quantitatively in the feces, while a part of the soluble can cross the intestinal barrier and be found in the blood, unchanged or as metabolites [3]. The antioxidant activity of food phenolic compounds is of nutritional interest, since it has been associated with the potentiation of the promoting effects of human health through the prevention of several diseases [11]. Additionally, in some cases, these compounds may also be used with therapeutic purposes due to their pharmacological properties [12].
