Transcription and numerous other genomic functions are epigeneti

Transcription and numerous other genomic functions are epigenetically controlled via heritable, but potentially reversible, changes in modification of DNA and histones (acetylation, methylation, phosphorylation, etc),1 and epigenomics is the application of these processes across the genome. The normal functioning of genomes is tightly connected to their epigenetic regulation, and epimutations can be harmful in the presence of impeccable DNA sequences. The epigenetic theory Inhibitors,research,lifescience,medical of complex non-Mendelian

disease is based on three key postulates. Firstly, an organism’s epigenetic status is far more dynamic than its DNA sequence, and may be altered by a number of factors, such as environment, developmental programs,2 or even as a result of stochasticity.3 Secondly, certain epigenetic signals may be inherited transgenerationally with DNA sequence4 and may account for heritability of some traits and diseases.5 Inhibitors,research,lifescience,medical Thirdly, epigenetic regulation is required in the maintenance of proper genomic function, for example, regulation of

gene activity, inactivation of parasitic DNA elements, and chromosomal segregation.6 Epigenetic factors greatly affect phenotype – even genes that are free of mutations may become harmful if they are not expressed Inhibitors,research,lifescience,medical at the appropriate time and at the required level. Combined, these points provide a solid, mechanistic basis for a cohesive interpretation of various epidemiological, clinical, and molecular features of complex diseases. The molecular epigenetic mechanisms are complex

and highly intertwined. At the most basic level, methyl groups may be bound to cytosines at the C5 carbon, usually within cytosine/guanine dinucleotides (CpG), which Inhibitors,research,lifescience,medical are established and maintained by the DNA methyltransferase (DNMT) family of enzymes. This is believed to be the most stable epigenetic mark, due to the covalent nature of the modification.7 Additionally, another DNA modification, Inhibitors,research,lifescience,medical hydroxymethylcytosine, has very recently been discovered in Purkinje neurons and other cells of the brain, and it may also play a role in epigenetic regulation of neural function.8 almost DNA is wrapped around octamers of basic histone proteins, each consisting of a core and N-terminus, to form nucleosomes. Numerous modifications of these proteins influence the condensation of chromatin, which can be open (transcriptionally active) or closed (learn more inactive). Histone acetyltransferases (HATs) acetylate lysine residues on the N-terminal tail of histone proteins, neutralizing the positive charge of the protein and decreasing its affinity for DNA. As a result, the chromatin relaxes and the transcription machinery gains access to previously restricted sites.9 Acetyl groups can be removed by histone deacetylases (HDACs), resulting in chromatin condensation and transcriptional inactivation.

15 The average working hours per week for male workers of the car

15 The average working hours per week for male workers of the car battery industry was more than 50 which possibly leads to the fatigue-related impact of long working hours and occupational dissatisfaction. However, a recent study on 96915 workers in the United States indicates that although males show greater risks of injury compared to females, working hours is significantly associated with toxic risk only for women. This is probably due to the decreased recovery time and inadequate sleep, and elevated fatigue-related impact of long working hours for female workers.17 Nevertheless, additional objective measures are warranted in order to come to a more reliable conclusion.

Chronic lead exposure Inhibitors,research,lifescience,medical is implicated in the development of hypertension.18 Although 23.2% of workers had higher than normal systolic or diastolic blood pressures, the diagnosis of hypertension could not be made in the first-time visit. Our findings showed no association between systolic/diastolic blood pressure and BLC, which was consistent with Inhibitors,research,lifescience,medical other reports.19,20 It seems that lead Inhibitors,research,lifescience,medical exposure was not sufficiently durable to cause hypertension in this young

population. In this study, the level of Compound Library education was inversely correlated with BLC which was consistent with the reports from other developing countries.21-23 Thus, improvement of education and socioeconomic status plays key role in the prevention of lead poisoning in these countries. According to guidelines,14 workers with severe lead poisoning should be hospitalized and treated with parenteral infusion. Since no severe case of lead poisoning was found among the studied population, Inhibitors,research,lifescience,medical workers were asked to avoid lead exposure and/or treated as outpatients. Toxicokinetics With normal renal function, lead is

excreted in the urine. Random urine sample shows short-term exposure to heavy metals.24,25 Urine and blood lead correlations are not reliable enough to substitute urine lead concentration for BLC, especially when the exposure is mild and BLC is less than 100 µg/L.24,26 Gulson et al, believed that the inaccuracy in predicting BLC by measuring ULC mostly applies Inhibitors,research,lifescience,medical to children and female adults because of the potential Rutecarpine contamination during sampling.24 On the other hand, Moreira et al. claimed that spot urine test could be used to replace blood sampling for the evaluation of occupational lead exposure in both children and adults.27 Hematologic Manifestations Lead poisoning is a known cause of microcytic anemia.1 Although we failed to detect depressed Hb/Hct concentrations in workers, Mean Corpuscular Hemoglobin (MCH) and Mean Corposcular Hemoglobin Concentration (MCHC) values were negatively correlated with blood lead concentration. Other RBC indices were not significantly affected. Katavolos et al. demonstrated that MCHC and hemoglobin concentration in two avian species decreased significantly with rising blood lead concentration.

The procedure is performed in the cardiac catheterization laborat

The procedure is performed in the cardiac catheterization laboratory with echocardiographic and fluoroscopic guidance while the patient is under general anesthesia. To JNK inhibitor access the left heart, standard transseptal catheterization is performed, and the guide catheter is then percutaneously inserted into the femoral vein. The delivery catheter is inserted into the guide, and the clip is positioned above the mitral valve. Manipulation of the steering mechanism on the handles of the guide and delivery catheter positions the clip on the mitral valve. The clip is actuated (i.e. opened and closed, locked, deployed) through manipulation of levers on the Inhibitors,research,lifescience,medical handle of the delivery catheter. More

than one clip can be delivered, and each one remains repositionable until detachment. Figure 1 MitraClip® System. The first MitraClip procedure was performed about 10 years ago.16 Inhibitors,research,lifescience,medical Subsequently, one randomized trial has proved MitraClip safety17 and short- to mid-term efficacy in selected patients.18 In the so-called “real world” the MitraClip therapy is usually reserved

to high-risk and extreme patients (mainly due to age, co-morbidities, and Inhibitors,research,lifescience,medical left ventricle dysfunction). Despite this, it has confirmed an excellent safety profile (30-day mortality 2%–5%) and acceptable mid-term outcomes (1-year survival 75%–85%, 1-year freedom from MR >2+ 80%) especially in terms of improvements in symptoms and quality of life.19–22 Major advantages of the MitraClip are its excellent safety even in end-stage patients and the possibility to operate on the beating heart, monitoring the efficacy of Inhibitors,research,lifescience,medical the implant during the procedure. On the other hand, MR recurrence (higher than in the surgical experience) is the most debated issue. Longer follow-up is needed to verify MitraClip outcomes in terms of MR recurrence and clinical benefit (survival and quality of life). European guidelines assigned an indication class IIb, level of evidence C, signifying that MitraClip may be considered Inhibitors,research,lifescience,medical in patients with symptomatic severe MR despite optimal medical therapy, who are judged inoperable or at isothipendyl high

surgical risk by a heart-team, and with life expectancy greater than 1 year.23 The randomized RESHAPE and COAPT trials, respectively in Europe and the US, are currently evaluating the benefit of MitraClip compared to optimal medical therapy to support a higher recommendation class in the forthcoming guidelines. A different approach to obtain transcatheter leaflet repair is off-pump adjustable chordal implantation, for which several devices are currently under development. The Babic device (from the name of the inventor, Uros Babic, MD)24 creates two continuous guiding tracks from the left ventricular puncture site through the target leaflet. The device is then exteriorized via the transseptal catheter and femoral vein.

40, 95% CI: 0.19–0.82; Bull et al. 2002). Therefore, increasing frequency of the follow-ups with focus to manage expectation on side effects and de-stigmatization over depression should be explored as a way to improve the noncontinuous use. These highlighted the importance of the need for FG4592 systematic psychoeducation on the depressive illness and reinforcement

of patients’ drug adherence as suggested in another local study conducted in patients with mood disorders Inhibitors,research,lifescience,medical (Lee et al. 1992). Limitations While this study evaluated both the prescription record and also the electronic and written medical records of patients, limitations related to retrospective data retrieval still apply when interpreting our findings. The use of retrospective data retrieved from the prescription database and

medical records may have underestimated the rate of noncontinuous use. As the data relied on patient reporting and prescription Inhibitors,research,lifescience,medical filling, it does not reflect the actual drug use of the patients. The sample size was relatively modest compared to previous studies using only claims database as source of data. However, the difference in relapse rate between the continuous and Inhibitors,research,lifescience,medical noncontinuous users was highly significant. Therefore, it is unlikely that our modest sample size critically affected our results and conclusions, although it is possible that not all relevant predictors for noncontinuous use were identified. Meanwhile, Inhibitors,research,lifescience,medical the exclusion of comorbid diagnosis or a past history of suicide may have potentially excluded a group of most severe depressive patients. Some studies have previously suggested an impact of concurrent use of benzodiazepine on the continuity of antidepressants, but this Inhibitors,research,lifescience,medical is beyond the scope of this study (Morgan et al. 2011). Finally, the unavailability of standardized, quantitative measurement for defining disease severity, relapses or remission was also one of the limitations in this study. Noncontinuous antidepressant

use is an important predictor of relapse and recurrence with significant implication for long-term prognosis. The results found in this Chinese population highlighted the high early recurrence only rate. Collaborative multidisciplinary approach utilizing various health care professionals to provide systematic psychoeducation on depressive illness and drug aspects should be explored.

Dopamine (DA) dysfunction is implicated in the modulation of pain perception and analgesia (Chudler and Dong 1995; Wasner and Deuschl 2012) and DA depletion plays a central role in this modulation. Indeed, hyposensitivity to pain is common in patients with schizophrenia, which is linked to excessive DA neurotransmission.

is that agents suc

A second explanation for these results

is that agents such as azacytidine, which cause global hypomethylation, likely reactivate expression of multiple silenced genes including oncogenes and tumour suppressors in different cell types and in different cancers. Demethylation could therefore cause both therapeutic and deleterious effects. For example, Inhibitors,research,lifescience,medical the oncogene NT5E is overexpressed in aggressive metastatic melanomas, yet transcriptionally silenced by methylation in breast cancer with more favorable prognosis [61]. A third and key possible explanation why DNMTi have advanced less rapidly in the clinic in solid tumours than in haematological malignancies is that of toxicity. Both decitabine and azacytidine are active in haematological malignancy at lower (less toxic) doses than are required for demethylation in epithelial malignancies. It is clearly of interest, therefore, that transient exposure of cells to low (relatively non-toxic) Inhibitors,research,lifescience,medical doses of these agents could induce a “memory” response with sustained reduction in CpG island methylation and reactivation of expression of previously silenced genes [62]. These observations imply that low-dose decitabine and azacytidine may have

wider uses in Inhibitors,research,lifescience,medical management of neoplastic disease than previously believed. In a recently reported phase II trial Matei et al. [60] showed that pretreatment with low-dose azacytidine restored sensitivity to Inhibitors,research,lifescience,medical carboplatin in patients with drug resistant epithelial ovarian cancer and resulted in a high response rate and significantly improved clinical outcomes. This study clearly attests to the utility of low-dose azacytidine in solid tumours and sets the scene for further Inhibitors,research,lifescience,medical studies. Newer azanucleosides are zebularine, S-110, and SGI-1027 that

have shown antiproliferative activity in cell lines [63, 64], but have not entered the clinical trial setting yet. 5.2.2. Histone Deacetylase Inhibitors (HDACi) The HDACs catalyse removal of acetyl groups from lysine residues in the histones and functionally are transcriptional repressors. HDACs are divided into five classes: class I comprises HDAC1, HDAC2, HDAC3, and HDAC8; class IIa comprises HDAC4, HDAC5, HDAC7, and HDAC9; class Resveratrol IIb contains HDAC6 and HDAC10; class III comprises the sirtuins SIRT1-SIRT7 while class IV contains only HDAC11 [65]. The discovery of HDACi actually preceded the discovery of HDACs. Sodium butyrate was the first HDACi described to induce acetylation [66], and later on trichostatin (TSA), a fungal antibiotic, currently used in in vitro experiments, and valproic acid, a widely used antiepileptic, were GSI-IX nmr identified. Valproic acid, in particular, has been used in combination with DNMTi and/or chemotherapy in patients with haematological malignancies [67, 68].

Most evidence that illegal drugs are risk factors for stroke is anecdotal (Brust 2002). Using the data from a number of case studies and a limited number of population studies, this article will outline various illicit drugs and their association to AIS, ICH, and subarachnoid hemorrhage (SAH). The main illicit drugs associated with stroke are cocaine, amphetamines, Inhibitors,research,lifescience,medical Ecstasy, heroin/opiates, phencyclidine (PCP), lysergic acid diethylamide (LSD), and cannabis/marijuana. Tobacco and ethanol are also associated with stroke, but will not be discussed here. This article will outline current epidemiology, pharmacology, evidence related to strokes, and mechanisms

of action related to stroke risk for each drug listed above. The table summarizes proposed stroke mechanisms for each reviewed drug and stroke subtype. Search strategy and selection criteria References for this review were identified by searches of PubMed from 1950 until February 2011 with the terms “ischemic stroke,”“intracerebral Inhibitors,research,lifescience,medical hemorrhage,”“subarachnoid hemorrhage,”“illicit drugs,”“substance abuse,”“cocaine,”“amphetamines,”“heroin,”“marijuana,”“phencyclidine,”“lysergic acid diethylamide,” Inhibitors,research,lifescience,medical and “Ecstasy.” Articles were also identified through searches of the authors’ own manuscripts and relevant publications. Only papers published in English were reviewed. Associated Drugs Cocaine In the 1970s, recreational

use of cocaine became widespread due to the production of crack cocaine, a purer and cheaper form of cocaine. The late 1980s saw an epidemic of cocaine: Inhibitors,research,lifescience,medical 30 million people of all socioeconomic backgrounds were cocaine users and 6 million were cocaine addicts (Agarwal and Sen 2010). In 2009, cocaine was the second-most commonly used illicit drug in the United States after marijuana. Of one million illicit drug-related ED visits yearly in the United States, nearly half are related to cocaine,

making cocaine the most frequent cause of illicit drug-related ED visits (The DAWN report 2010). Pharmacology Cocaine comes in two chemical forms: the hydrochloride Inhibitors,research,lifescience,medical salt, which is the powdered form of cocaine that is water soluble, and cocaine PI3K inhibitor alkaloid, a free base that is lipid soluble. The effects of cocaine include local anesthesia, vasoconstriction, and central nervous system stimulation. Cocaine prevents neurotransmitter (dopamine, norepinephrine, Fossariinae serotonin, and acetylcholine) reuptake at presynaptic nerve terminals, thereby increasing the amounts of neurotransmitters available for stimulation of sympathetic nerves. The euphoria related to cocaine use is a result of accumulation of dopamine and serotonin in the mesolimbic and mesocortical areas of the brain (Treadwell and Robinson 2007). These reward circuits are related to drug-seeking behavior, addiction, and dependence, making cocaine one of the most potent and highly addictive chemicals (Goforth et al. 2010).

Nearly $0.5 trillion dollars per annum is spent on treating cardiovascular diseases. Coronary artery disease (CAD), stemming from atherosclerosis, is the leading cause of death from myocardial infarction in the western world. In the United States, CAD results in about one-third of total deaths.1 Many of these patients succumb to thrombi that form rapidly and occlude vessels completely after rupture of atherosclerotic plaques.

In many cases, plaques that rupture are nonstenotic (most cause less than 50% luminal narrowing) and evade detection by traditional imaging methods (i.e., X-ray angiography, Inhibitors,research,lifescience,medical intravascular ultrasound).2–6 Consequently, DAPT treatment of CAD does Inhibitors,research,lifescience,medical not occur until the blood flow has been severely compromised, and it usually involves surgical intervention. Such an invasive procedure is by nature undesirable, does not address the underlying cause of the myocardial infarction, and thus fails to prevent reoccurrence. Statin treatment has been effective at reducing acute coronary complications due to atherosclerosis; nonetheless, acute complications continue to occur in

more than half of the patients, and aggressive statin treatment has been associated with serious side effects.7 8 Development Inhibitors,research,lifescience,medical of effective noninvasive imaging methods for early detection and consequent therapy that can treat the underlying causes of CAD and other cardiovascular diseases remain a major focus of cardiovascular research. Nanovectors offer potential for improving current treatment options through more complete imaging information and delivery of drugs specifically targeted

to tissues affected by disease. There are numerous biochemical processes Inhibitors,research,lifescience,medical associated with the pathogenesis and destabilization of plaques that Inhibitors,research,lifescience,medical precede anatomical and physiological changes. By targeting the presence or activity of proteins associated with these biological processes, clinicians can identify nonstenotic vulnerable plaques before rupture and treat the underlying cause of plaque destabilization. The ability to detect these proteins with diagnostic imaging techniques has stimulated the development of targeted nanovectors containing contrast-enhancing agents. This form of imaging, known as molecular imaging, has been used to detect angiogenesis in early stage atherosclerosis and the activity of matrix metalloproteinases, Sitaxentan a protease involved in plaque remodeling and destabilization.9–11 Upon diagnosing the stage and determining the extent of disease, nanovectors can transport therapeutics specifically to the diseased tissue, thus localizing treatment and reducing adverse side effects associated with systemic administration.12 To be successful, targeted drug delivery and/or imaging systems must reach their intended destination in functional form.

Also, the influence of air within the lung might also impair the ability of US waves to penetrate and deliver genes in the lung. Typically, sonoporation agents (also useful as US contrast agents) can be composed of micro- or nanoparticles filled with either air or gases, which give echogenic properties, surrounded by a shell of lipids or polymeric formulations. Gas-filled

lipid particles are called microbubbles (MBs), while echogenic polymeric particles can be defined as either nanoparticles (NPs) or microparticles Inhibitors,research,lifescience,medical (MPs) depending on their size. Different types of MB have been synthesized by combining different shell compositions such as albumin, galactose, lipids, or polymers, with different gaseous cores such as air, or high-molecular-weight gases (perfluorocarbon,

sulphur hexafluoride, or nitrogen) and several types are available commercially (reviewed in [5]). This paper will focus on echogenic NP use in combination with US-mediated sonoporation Inhibitors,research,lifescience,medical to induce gene delivery. The mechanism of sonoporation involves the motion of MB or NP and disruption induced by low-intensity US sonication (Figure 1). US increases the permeability of cell membranes and the endothelium, thus enhancing therapeutic uptake, and can locally increase drug/nucleic acid transport. Formation of short-lived nanopores (~100nm) in the plasma membrane lasts a few Inhibitors,research,lifescience,medical seconds and is implicated as the dominant mechanism associated Inhibitors,research,lifescience,medical with acoustic cavitation [6]. Sonoporation mediates delivery of drugs and/or nucleic acids that have been incorporated into or on the surface of nano/microparticles via covalent or electrostatic interactions, which allow these complexes to circulate in the blood and retain their cargo until

activation by US. US application results in localized and spatially controlled particle disruption that enhances gene/drug delivery. Sonoporation-mediated gene delivery has been applied to date in heart, blood vessels, lung, kidney, muscle, brain, and tumors with high efficiency [7]. However, in order Inhibitors,research,lifescience,medical to provide high transfection efficiency, ultrasonic parameters Adenosine (such as acoustic pressure, pulse length, duty cycle, repetition rate, and exposure duration) and nano- or microparticle properties (such as size and echogenic characteristics of air- or gas-filled preparations) should be optimized [7]. The efficiency of drug/gene delivery typically correlates to the cell location VE-821 cost relative to the US (transducer and its proximity to acoustically active nano- or microparticles). At ~1MHz US, echogenic nano/microparticles or microbubbles oscillate steadily. It has been shown that lipid-shelled MB can expand from 2μm to ~20–55μm [8]. When MBs expand and collapse near a cell wall, a fluid jet/shock wave is formed followed by an increase in vascular permeability [9].

Six patients had a partial response, defined as ≥50% but ≤90% reduction in wet nights. Overall, 4 of the 25 patients (16%) presented with a relapse after 6 months of follow-up. No drug-emergent adverse events were observed. Figure 1 Mean number of wet nights after JSH-23 order treatment with sertraline. Only 3 of the 25 patients had adverse reactions of moderate intensity, requiring no early treatment cessation. The affected patients reported headache and nausea. By using a generalized estimating equation approach, the risk of wet episodes per night was compared showing a significant decrease of 74% in the risk of a wet episode in the study group. Discussion Inhibitors,research,lifescience,medical MacLean12 noticed that imipramine, a tricyclic antidepressant,

improved patients’ enuresis. Mesaros13 discovered the therapeutic effect of SSRIs on nocturnal enuresis, when treating dysthymia. Kano proposed Fluvoxamine as a possible drug for the treatment of enuresis with respect to his experience Inhibitors,research,lifescience,medical in patients with obsessive-compulsive disorder.9 Toren and collegues14 were the first to evaluate the efficacy of Fluvoxamine in the treatment of enuresis in children and adolescents. In their case series, no improvement in the mean voiding frequency

of patients was observed. Conversely, 4 of 9 patients showed Inhibitors,research,lifescience,medical a trend toward an increase in the frequency of enuresis during treatment. The author concluded that fluvoxamine had no anti-diuretic properties. However, the small number of subjects and mixed target population of the patients should be considered. In the current study, the effect of sertraline was investigated in adolescent PME patients who had Inhibitors,research,lifescience,medical failed to respond to previous desmopressin therapy. The frequency of enuresis decreased in 18 (72%) patients. Water intoxication is a rare but serious side effect associated with desmopressin.15 Imipramine has important adverse effects, and overdose can be lethal. The known side effects of sertraline

Inhibitors,research,lifescience,medical include sleep disturbance, headache, tremors, agitation, and gastrointestinal upset. In the current investigation, drug adverse effects were observed only in 3 patients, which did not warrant withdrawal from the study. This study demonstrates that sertraline could be of value in some PME in whom previous conventional therapy with desmopressin has failed. To our knowledge, this treatment modality has not been tried before in such cases. However, at 6-month follow-up off-sertraline, we detected some deterioration MYO10 in the response rate compared to early results and 4 (16%) patients experienced relapse. This deterioration during follow-up suggests that sertraline may have temporary efficacy and its effect may decrease gradually with time. It has been noted in the medical literature that serotonin level alteration has specific effects on urination. Serotonin inhibits ureteral peristalsis as well as micturition by interfering with spinal reflexes, primarily through 5-HT3 receptor agonism.

Specifically we examined the influence of age, gender, ethnicity on survival. We also explored the interactions between patient characteristics and tumor histology, grade, size, and location (cardia vs non-cardia). Patients and methods Data source Adult patients with metastatic gastric cancer were identified from the SEER registry 1988-2004 database, which collects SB-715992 Information on all new cases of cancer from 17 population-based

registries covering approximately 26% of the US population. Study population The disease was defined by the following International Classification of Diseases for Oncology (ICD-O-2) codes: C16.0-C16.9. We identified patients (n=15,360) who had metastatic Inhibitors,research,lifescience,medical disease defined by SEER Extent of Disease code: 85. We restricted eligibility to adults (aged 18 years or older) who were diagnosed with metastatic gastric cancer (MGC) in 1988 and later (n=15,348);

Inhibitors,research,lifescience,medical because the record of extent of disease was not available for accurate staging prior to 1988. We excluded cases (less than 10% of adult patients with metastatic gastric cancer) who were diagnosed at death certificate or autopsy, no follow-up records (survival Inhibitors,research,lifescience,medical time code of 0 months), as well as lacking documentation on race/ethnicity. A total of 13,840 MGC patients of 18 years and older were included in the final sample for the current analysis. Variable definitions Information on age at diagnosis, sex, race, and ethnicity, marital Inhibitors,research,lifescience,medical status, treatment type, primary site, tumor grade and differentiation, histology, tumor size, and lymph node involvement, and overall survival were coded and available in SEER database. The primary endpoint in this study was overall survival that was defined as the months lapsing from diagnosis to death. For the patients who were still alive at last Inhibitors,research,lifescience,medical follow-up, overall survival was censored at the date of last follow-up or December 31, 2004, whichever came first. Age. We chose the cut points for age groups based on the previous studies (18-44, 45-54, 55-64, 65-74, and 75 and older). Ethnicity. Patients were divided into

five ethnic groups, why “Caucasian” (Race/Ethnicity code, 1), “African American” (Race/Ethnicity code, 2), “Asian” (Race/Ethnicity code, 4-97), “Hispanic” (Spanish/Hispanic Origin code, 1-8), and Native American (Race/Ethnicity code, 3). Primary site. According to the latest guidelines for gastric cancer classificationa, the stomach is anatomically delineated into the upper, middle, and lower thirds by dividing the lesser and greater curvatures at two equidistant points and joining these points. The sites were defined by the following codes from ICD-O-2: Cardia, (C16.0), Body (C16.1-2, C16.5-6), Lower (C16.3-4), and Overlapping lesion of stomach (C16.8). For the ones that are not specified, they were categorized together as Stomach, NOS (C16.9). Marital status.
