Background: CEA and CA 15.3 serum tumor markers are currently used in clinical practice for monitoring therapy. The aim of this study was to evaluate serum level of these markers among healthy females and invasive breast carcinoma (IBC) patients and to determine any relationships with clinicopathological factors. Materials and Methods: 60 Iranian females were enrolled in this study, 30 healthy and 30 diagnosed with breast cancer who had not received any preoperative chemotherapy or hormone therapy. Enzyme linked immunosorbent assays were used for the quantitative determination of the cancer associated antigens, CEA and MUC1 (CA15-3). Results: The serological levels of CEA and CA15-3 ($5.0033{\pm}0.49{\mu}g/L$ and $178.1667{\pm}15.11$ U/ml) in the breast cancer patients were significantly higher (p=0.00) than the serum levels of normal controls ($1.1237{\pm}0.11{\mu}g/L$ and $21.13{\pm}3.058$ U/ml). Regarding the CEA marker, a significant correlation with grade of tumor was shown. Furthermore, there was a low correlation between CA15-3 and CEA marker with correlation coefficient r=0.08. Conclusions: Collectively, markedly high levels of CEA and CA15-3 were found in our patients, pointing to their use as additional tools after clinical diagnosis.

Objectives : We proposed the hypothesis that administering Trigonella foenum-graecum seed extract (TSE) could alleviate menopausal symptoms and osteoporosis resulting from estrogen deficiency. Methods : Ovariectomized (OVX) rats were administered TSE at doses of 300 or 600 mg/kg body weight for 8 weeks, followed by measurement of serum lipid profile and serum bone markers using ELISA kits. Additionally, analysis of related genes in the femur and uterus was performed using Western blot and real-time PCR. Additionally, micro-CT analysis was performed to investigate the protective effect of TSE against bone loss due to oophorectomy. Results : The administration of TSE led to significant reductions in triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, and glucose levels in the serum of OVX rats. Furthermore, TSE increased estradiol levels in the serum and notably improved the levels of biochemical markers associated with bone metabolism. Additionally, TSE exerted significant regulatory effects on the mRNA levels of alkaline phosphatase (ALP) and receptor activator of nuclear factor kappa-B ligand (RANKL)-genes closely associated with bone metabolism in the femur. TSE also demonstrated pronounced effects on uterine tissue, with improvements observed in gene expression related to estrogen receptors. Conclusion : Our findings confirm the efficacy of TSE in ameliorating menopause symptoms by modulating elements associated with both bone and lipid metabolism in the serum, uterine tissue, and femur of OVX rats. The present findings suggest that TSE may offer potential therapeutic effects for symptoms related to menopause and osteoporosis in females.

Our aim was to investigate the value of combined detection of serum carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9, CA 242 and CA 50 in diagnosis and assessment of prognosis in consecutive gastric cancer patients. Clinical data including preoperative serum CEA, CA 19-9, CA 242, and CA 50 values and information on clinical pathological factors were collected and analyzed retrospectively. Univariate and multivariate survival analyses were used to explore the relationship between tumor markers and survival. Positive rates of tumor markers CEA, CA 19-9, CA 242 and CA 50 in the diagnosis of gastric cancer were 17.7, 17.1, 20.4 and 13.8%, respectively, and the positive rate for all four markers combined was 36.6%. Patients with elevated preoperative serum concentrations of CEA, CA 19-9, CA 242 and CA 50, had late clinical tumor stage and significantly poorer overall survival. Five-year survival rates in patients with elevated CEA, CA 19-9, CA 242 and CA 50 were 28.1, 25.8, 27.0 and 24.1%, respectively, compared with 55.0, 55.4, 56.4 and 54.5% in patients with these markers at normal levels (p<0.01). In multivariate Cox proportional hazards analyses, an elevated CA 242 level was determined to be an independent prognostic marker in gastric cancer patients. Combined detection of four tumor markers increased the positive rate for gastric cancer diagnosis. CA 242 showed higher diagnostic value and CA 50 showed lower diagnostic value. In resectable gastric carcinoma, preoperative CA 242 level was associated with disease stage, and was found to be a significant independent prognostic marker in gastric cancer patients.

Currently bone biochemical markers are considered to be the best indicators of present and the future state of bone turnover. A recent study has reported that chlorella increases the bone mineral density (BMD) on postmenopausal women, but presently there are no studies on bone biochemical markers treated with chlorella dietary supplementation. The purpose of the present study was to assess the bone biochemical markers for the short term and long term treatment groups, and non-treatment group as a control. Twenty two postmenopausal woman were treated for four months and eighteen for one year with 4 gm of chlorella dietary supplementation per day, and then assessed bone biochemical markers from serum and urine samples. Bone turnover rates calculated with Osteocalcin (OC), bone specific alkaline phosphatase (BAP) as a bone formation markers and deoxypyridinoline (DP), cross-linked N-telopeptides of type I collagen (NTx) as a bone resorption markers, showed 1131$\pm$87% for control group, 61$\pm$11% for short term treated group and 190$\pm$101% for long term treated group. We conclude that chlorella dietary supplementation enhances the bone formation, and NTx as a single markers, OC/Dp as a single markers of bone turnover rate were very useful tools for determine the effectiveness of chlorella dietary supplementation (or the postmenopausal women.

Purpose: To compare Ki-67 index and microvessel density MVD) in multiple myeloma and non-myeloma patients and their correlation with each other and other prognostic markers. Materials and Methods: Forty patients were enrolled in this study between 2011-2013, 30 with multiple myelomas and 10 with non-malignant disease as controls. Proliferative activity was analyzed by Ki-67 and microvessel density (MVC) was assessed by CD34 and compared between two groups. In myeloma patients, correlation between Ki-67, MVD and other prognostic factors was assessed by Pearson correlation coefficient. Results: According to Durie Salmon staging criteria, 13 patients were of stage 1, 5 of stage II and 12 of stage III. Ki-67 expression showed a positive correlation with MVD (r=0.729, p<0.001) and was significantly higher (p<0.0001) in myeloma patients (range 35-80%, mean 60.1 %) as compared to controls (range 8-25%, mean 18.1%). $MVD/mm^2$ was also significantly (p<0.0001) higher in myeloma patients (range $62-237/mm^2$, mean $178.0/mm^2$) than controls (range $5.2-50/mm^2$, mean $18.3/mm^2$). Ki-67 and MVD, both increased progressively with increasing stage of myeloma. Ki-67 showed significant positive correlation with blood urea and lactate dehydrogenase and a significant negative correlation with serum albumin. MVD showed a significant positive correlation with blood urea, lactate dehydrogenase, serum creatinine, ${\beta}2$ microglobulin and skeletal lesions. Conclusions: Ki-67 and MVD are indicators of aggressiveness and poor prognosis having significant correlation with each other and other prognostic markers of multiple myeloma. Routine assessment of these markers may help to identify high risk patients, who may benefit from with more aggressive therapy.

Objective: Neuropsychiatric manifestations like depression and cognitive dysfunction commonly occur in inflammatory bowel disease (IBD). In the context of the brain-gut axis model, colitis can lead to alteration of brain function in a bottom-up manner. Here, the changes in the response of the hypothalamic-pituitary-adrenal axis and inflammation-related markers in the brain in colitis were studied. Methods: Dextran sodium sulfate (DSS) was used to generate a mouse model of colitis. Mice were treated with DSS for 3 or 7 days and sacrificed. We analyzed the gene expression of brain-derived neurotrophic factor (BDNF), cyclooxygenase 2 (COX-2), and glial fibrillary acidic protein (GFAP), and the expression of GFAP, in the hippocampus, hypothalamus, and amygdala. Additionally, the levels of C-reactive protein (CRP) and serum cortisol/corticosterone were measured. Results: Alteration of inflammatory-related markers varied depending on the brain region and exposure time. In the hippocampus, COX-2 mRNA, GFAP mRNA, and GFAP expression were upregulated during exposure to DSS. However, in the hypothalamus, COX-2 mRNA was upregulated only 3 days after treatment. In the amygdala, BDNF and COX-2 mRNAs were downregulated. CRP and corticosterone expression increased with DSS treatment at day 7. Conclusion: IBD could lead to neuroinflammation in a bottom-up manner, and this effect varied according to brain region. Stress-related hormones and serum inflammatory markers, such as CRP, were upregulated from the third day of DSS treatment. Therefore, early and active intervention is required to prevent psychological and behavioral changes caused by IBD, and region-specific studies can help understand the precise mechanisms by which IBD affects the brain.

This study was conducted to observe the effect of vitamin K on bone metabolism in postmenopausal women. Twenty-four healthy postmenopausal women recruited for this one-month, double-blind controlled study. Before and after daily administration of 1.0mg of phylloquinone the levels of serum vitamin K, osteocalcin, under-carboxylated osteocalcin, and urinary deoxy-phyidinoline were measured. The serum vitamin K concentration of Koran women as well as the average dietary intake of vitamin K was shown to be higher than the average levels of foreign women. However, no correlation between serum vitamin K concentration and vitamin K intake was found. Also, serum vitamin K concentration showed no special correlation with either bone mineral density or bone turnover markers in the study group. However, women with low serum vitamin K concentration(vitamin K-low group)had lower bone mineral density levels. After supplementation with 1.0mg/day of vitamin K, there were no changes in the levels of serum vitamin K, osteocalcin, ucOC, or u-DPD. Vitamin K supplementation did not seem to have any positive effects on bone metabolism through carboxylation. It can, however, be expected that vitamin K supplementation has a positive effect on bone metabolism in postmenopausal women with especially low serum vitamin K concentrations.

Objectives: This study was designed to investigate the significance of serum SCC antigen, CA 19-9, CA 125 level and DNA microsatellite alterations (MSA) as prognostic factors and indicators for recurrences in the pre-treatment and post-treatment state, respectively in head and neck cancer patients. Materials and Methods: 120 patients who received curative treatment for head and neck cancer from 1995 to 2000 were followed up successfully, and were analyzed retrospectively. Thirty healthy subjects served as normal controls. Serum SCC Ag levels were measured by microparticle enzyme immunoassay technique via IMX SCC assay, CA 19-9 levels were measured by CA 19-9 RIA test kit, and CA 125 levels were measured by CA 125 IRMA kit. MSA were identified after PCR amplification. Heterozygosity was considered lost if the ratio of one allele was significantly decreased (>50%) in serum DNA compared with normal DNA from lymphocytes. Results: Preoperative tumor markers were higher in cancer patients than control, but not significant. Postoperative SCC Ag levels were lower than preoperative levels. The SCC Ag levels were remained low in no evidence of disease (NED) group, but increased in locoregional recurrence and distant metastasis group. CA 19-9 and CA 125 levels showed no correlation between levels and recurrences and were not decreased significantly after primary tumor removal. MSA were detected in five out of 21 cases, and highly detected in distant metastasis group. Conclusion: SCC Ag seems to be a helpful serum tumor marker for early detection of recurrence and distant metastasis of head and neck cancer after curative treatment. But, CA 19-9 and CA 125 were not reliable markers for head and neck tumors. MSA were not statistically significant because of the small number of study group. However they may be helpful for screening serum molecular markers for early detection of distant metastasis of head and neck cancers.
