Fifty four crossbred gilts of 26.38${\pm}$0.85 kg body weight and 25 weeks of age were randomly divided into three groups, having six replicates of three animals each and were assigned to one of the three dietary treatments containing corn, wheat bran and rice bran (RB) at 35, 47 and 0% in $R_1$; 17.5, 23.5 and 41% in $R_2$ and 0, 0 and 82% in $R_3$. Soybean meal and fishmeal were used as source of protein at 10 and 6%, respectively, in all the rations. Average daily CP, DCP, DE and ME intake per kg $W^{0.75}$ and body weight gains were lowest (p<0.01) in gilts fed 82% RB ($R_3$), followed by $R_2$ and R1. Utilization of protein with respect to nitrogen balance and DCP conversion efficiency did not differ (p>0.05) between the treatment groups. All the gilts were in positive nitrogen balance. However, the excretion of dietary nitrogen and energy through faeces was higher (p<0.01) in gilts fed RB. However, the DE and ME conversion efficiency were higher (p<0.01) in gilts fed RB. Therefore, it can be concluded that the digestibility of energy and protein in diets containing rice bran goes on decreasing with the increasing level of fat and fibre, but the metabolizability of the energy and protein was better in pigs fed RB in the diet.

We investigated the effects of the mitogen supplements of 3 types, pokeweed mitogen (PWM), phytohemagglutinin (PHA) and concanavalin A (ConA), to a whole blood culture system on the number of metaphase spreads obtained in perinatal bovine chromosome analysis. In addition, the supplementation of ${\beta}$-mercaptoethanol (${\beta}$-ME) and FBS was examined in such system. Significant differences (p<0.05) were seen in the number of metaphase spreads with PHA stimulation compared to both PWM and ConA stimulation. When examined the effects of ${\beta}$-ME supplementation, the number of metaphase spreads was significantly (p<0.05) increased at $30{\mu}M$${\beta}$-ME compared to control. When evaluated FBS supplementation during PWM stimulation, no significant effect of the supplementation was found. Finally, the effects of the cortisol concentration (10-20, 20-30 and >30 ng/ml) of the blood samples were examined. There was no significant effect of cortisol concentration (p>0.05) among these 3 cortisol concentration groups. The mean percentages of normal metaphase plates (2n=60) from each calf 1) with ${\beta}$-ME, 2) without ${\beta}$-ME and 3) with FBS stimulated with PWM were not significantly different (p>0.05). In conclusion, these findings may be useful in cytogenetic screening programs for not only perinatal calves but also for mature cattle.
Nutritive values and fermentation rates of rice straw treated with 3% anhydrous and 3% aqueous ammonia were evaluated both in vitro and sheep metabolism trials. Daily gain, feed efficiency and feed cost per gain were also determined with growing Holstein bulls fed anhydrous and aqueous ammonia treated rice straw. Crude protein was increased 2.4 fold and NDF was decreased 6.5%, but ADF and cellulose were not different between untreated and ammonia treated rice straw. An average of 35.5% of total added ammonia-N retained in the rice straw and other 64.5% was not retained in the rice straw. Ammonia treatment increased in vitro DM, NDF, ADF and cellulose digestibilities by 44.8%, 43.3%, 49.4% and 42.4%, respectively, and fermentation rates by 63.3%, 132.4%, 49.4% and 42.4%, respectively. In sheep metabolism trials, DM digestibilities of rice straw treated with anhydrous and aqueous ammonia were increased 22% and 36%, respectively, and digestible DM intakes by 48% and 70%, respectively in sheep fed anhydrous and aqueous ammonia treated rice straw over untreated rice straw. Rumen ammonia and blood urea were considerably higher in sheep fed ammonia treated rice straw than sheep fed untreated rice straw. Daily gain of Holstein bulls was increased 20.8% and 29.9% and rice straw intakes were increased 28.4% and 44.3% in anhydrous and aqueous ammonia treated rice straw over untreated rice straw. Feed conversion was improved 9.5% and 10.3% and feed cost/gain was reduced 7.1% and 9.2% respectively in anhydrous and aqueous ammonia treated rice straw group as compared with untreated rice straw group.
This study compared the effects of two levels of crude protein (CP) supplementation during a close-up dry period on the productive performance, nitrogen balance, and blood profiles of Holstein cows. Eighteen cows (8 primigravid and 10 multiparous), 21 days prior to calving, were divided into four groups and fed a diet containing a low (11.5 to 12.7% CP) or high (14.1 to 15.3% CP) level of protein. Following parturition, all cows were offered the same diet. Nitrogen balance was measured 12 d to 10 d prior to the expected calving date. Whole feces and urine were collected. The higher close-up CP did not improve milk production during the early lactation period (14 w) in multiparous cows but tended to increase production by 2 kg of milk per day in primigravid cows. There were no differences in the weight of calves, the weight of the placenta, or the incidence of calving difficulty. Nitrogen intake, urine nitrogen and nitrogen retention were increased by the higher CP diet in primigravid and multiparous cows. All groups of cows showed a positive nitrogen balance. In particular, higher nitrogen retention was observed in primigravid cows fed the higher CP diet. With the exception of plasma urea nitrogen (PUN), non of the blood profiles were influenced by the CP level. The higher close-up CP increased the PUN during the period studied in primigravid and multiparous cows. These results indicate that a CP level of 14% during a close-up dry period is optimal for primigravid cows, and 12% CP level is sufficient for multiparous cows.
Twelve cross bred cows ($300{\pm}20kg$) were fed a basal ration consisting of 1 kg concentrate and untreated or urea treated rice with or without urea-molasses-wheat bran lick block supplementation. The lick blocks were prepared locally using cement as a binding agent. The experiment lasted for 48 days consisting of a preliminary period of 14 days and a measurement period of 34 days. Daily dry ma tter intake (DMI) of straw and lick block, and daily milk yield were recorded during the measurement period. Intake of lick block when fed with untreated straw (US) was significantly higher (p < 0.01) than with urea treated (TS) straw (397 vs 307g $100kg^{-1}$), but lick block supplementation did not significantly affect the in take of US (1.80 vs 1.83kg $100kg^{-1}day^{-1}$) or TS (2.27 vs 2.17kg $100kg^{-1}day^{-1}$). Both urea treatment and lick block supplementation significantly increased (p < 0.01) the milk yield of cows, and the increase due to urea treatment was higher than that due to lick block supplementation. Benefit/cost ratio obtained for feeding US or TS with 1 kg dairy concentrate was similar (5.4), but the marginal return favours TS (5.4:1.0). The benefit/cost ratio for US and TS supplemented with lick block was 3.4 and 3.7. respectively, but the marginal return with US was higher than with TS (1.6:1.0 and 0.9:1.0, respectively).
Purpose: This study was conducted to explore the degree of depression, perceived health status, chronic disease and quality of life(QOL) among rural elderly and to determine the factors related to their QOL. Method: The design of this study was a correlational study. The subjects were 423 elderly consisted of 157(37.1%) men and 266(62.9%) women dwelling in a rural area of N City. Data were collected from May to December, 2003 using a structured questionnaire. A stepwise multiple regression analysis was performed to identify the factors related to the QOL. Result: It was found that the mean score of QOL was in total with 2.15 out of 5.00 and women elderly's score was significantly lower than men(t=2.20, p=.028). Perceived health status showed statistically significant positive relationship with QOL(r=.608, p<.05), while depression(r=-.751, p<.01) and chronic illness(r=-.336, p<.01) showed statistically significant negative relationship. Depression was found to have the highest correlation with QOL among the subjects. Depression score explained QOL at the most, accounting for 36.8% of the variability, followed by perceived health(8.2%) and the number of chronic illness(.7%). Other factors related to the QOL were economic status and absence of spouse. Conclusion: In order to increase the QOL of rural elderly, it is necessary to decrease the depression, to increase their perceived health status and to decrease the number of chronic illness. We suggest the implementation of a program not only to promote physical health status and self-care ability but to take care of mental health for the rural elderly.
Background: Breast cancer is the commonest female cancer worldwide and its propensity to metastasize negatively impacts on therapeutic outcome. Several clinicopathological parameters with prognostic/predictive significance have been associated with metastatic suppressor expression levels. The role of metastatic suppressor gene (MSG) KiSS1 in breast cancer remains unclear. Our goal was to investigate the possible clinical significance of KiSS1 breast cancer. Materials and Methods: The study was conducted on 87 histologically proven cases of breast cancer and background normal tiisue. Quantitative reverse transcriptase polymerase chain reaction (qRT PCR) and immunohistochemistry (IHC) were used to investigate KiSS1 at gene and protein levels, respectively, for correlation with several patient characteristics including age, family history, hormonal receptor status, stage, tumor size, nodal involvement and metastatic manifestation and finally with median overall survival (OS). Results: Our study revealed (i) KiSS1 levels were generally elevated in breast cancer vs normal tissue (P < 0.05). (ii) however, a statistically significant lower expression of KiSS1 was observed in metastatic vs non metastatic cases (P = 0.04). (iii) KiSS1 levels strongly correlated with T,N,M category, histological grade and advanced stage (p<0.001) but not other studied parameters. (iv) Lastly, a significant correlation between expression of KiSS1 and median OS was found (P = 0.04). Conclusions: Conclusively, less elevated KiSS1 expression is a negative prognostic factor for OS, advancing tumor stage, axillary lymph node status, metastatic propensity and advancing grade of the breast cancer patient. Patients with negative KiSS1 expression may require a more intensive therapeutic strategy.
Side population (SP) cells have stem cell-like properties with a capacity for self-renewal and are resistant to chemotherapy and radiotherapy. Therefore the presence of SP cells in human breast cancer probably has prognostic value. Objective: To investigate the characteristics of SP cells and identify the relationship between the SP cells levels and clinico-pathological parameters of the breast tumor and disease-free survival (DFS) in breast cancer patients. Materials and Methods: A total of 122 eligible breast cancer patients were consecutively recruited from January 1, 2006 to December 31, 2007 at Yunnan Tumor Hospital. All eligible subjects received conventional treatment and were followed up for seven years. Predictors of recurrence and/or metastasis and DFS were analyzed using Cox regression analysis. Human breast cancer cells were also obtained from fresh human breast cancer tissue and cultured by the nucleic acid dye Hoechst33342 with Verapami. Flow cytometry (FCM) was employed to isolate the cells of SP and non-SP types. Results: In this study, SP cells were identified using flow cytometric analysis with Hoechst 33342 dye efflux. Adjusted for age, tumor size, lymph nodal status, histological grade, the Cox model showed a higher risk of recurrence and/or metastasis positively associated with the SP cell level (1.75, 1.02-2.98), as well as with axillary lymph node metastasis (2.99, 1.76-5.09), pathology invasiveness type (1.7, 1.14-2.55), and tumor volume doubling time (TVDT) (1.54, 1.01-2.36). Conclusions: The SP cell level is independently associated with tumor progression and clinical outcome after controlling for other pathological factors. The axillary lymph node status, TVDT and the status of non-invasive or invasive tumor independently predict the prognosis of breast cancer.

Aim: To report epidemiologic and anatomoclinical transitions of inflammatory breast cancer (IBC) in Tunisia. Materials and Methods: Data including clinico-pathological data for 208 cases of T4d or PEV 3 non-metastatic breast cancer diagnosed between 2005 and 2010 were collected from patient records. Chi2 and Z tests were used to compare variables with two Tunisian historical series and a series about Arab-American patients. Results: Thirty three percent of our patients had their first child before 23 years of age and 56% had their menarche before 12 years, 75% never receiving oral contraception. Obesity was observed in 42% of women and IBC occurred during pregnancy in 13% of cases. Tumor grade was II-III in 90% of cases, HR was negative in 52%, HER2 was over expressed in 31% and invasion of more than 3 axillary nodes occurred in 18% of patients. We observed a pCR rate of 19% after neoadjuvant treatment (anthracyline-taxane used in 79%, trastuzumab in 27% ). Compared to historical Tunisian series (since 1996), IBC epidemiology remained stable in terms of median age, menopausal status and obesity. However we observed a significant decrease in median clinical tumor size and number of positive axillary lymph nodes. Comparison to IBC in Arab-Americans showed a significant difference in terms of median age, menopausal status, positivity of hormonal receptors and educational level. Conclusions: Our assessment of epidemiologic transition showed a reduction of clinco-pathological stage of IBC, keeping the same characteristics as compared to Tunisian historical series over a period of 14 years. Features seem to be different in Arab-American patients, probably related to migration, "occidentalization" of life style and improvement in socio-economic level.
Background: Turmeric ($Curcuma$$longa$) has been shown to possess anti-inflammatory, antioxidant and antitumor properties. However, despite the progress in research with $C.$$longa$, there is still a big lacuna in the information on the active principles and their molecular targets. More particularly very little is known about the role of cell cycle genes $p57^{kip2}$ and Rad9 during chemoprevention by turmeric and its derivatives especially in prostate cancer cell lines. Methods: Accordingly, in this study, we have examined the antitumor effect of several extracts of $C.$$longa$ rhizomes by successive fractionation in clonogenic assays using highly metastatic PC-3M prostate cancer cell line. Results: A mixture of isopropyl alcohol: acetone: water: chloroform: and methanol extract of $C.$$longa$ showed significant bioactivity. Further partition of this extract showed that bioactivity resides in the dichloromethane soluble fraction. Column chromatography of this fraction showed presence of biological activity only in ethyl acetate eluted fraction. HPLC, UV-Vis and Mass spectra studies showed presence three curcuminoids in this fraction besides few unidentified components. Conclusions: From these observations it was concluded that the ethyl acetate fraction showed not only inhibition of colony forming ability of PC-3M cells but also up-regulated cell cycle genes $p57^{kip2}$ and Rad9 and further reduced the migration and invasive ability of prostate cancer cells.
