  • Maintaining a high level of beef consumption requires paying attention not only to quantitative traits but also to the quality and dietary properties of meat. Growing consumer demands do not leave producers many options for how animals are selected for breeding and animal keeping. Meat and carcass fatness quality traits, which are influenced by multiple genes, are economically important in beef cattle breeding programs. The recent availability of genome sequencing methods and many previously identified molecular markers offer new opportunities for animal breeding, including the use of molecular information in selection programs. Many gene polymorphisms have thus far been analyzed and evaluated as potential candidates for molecular markers of meat quality traits. Knowledge of these markers can be further applied to breeding programs through marker-assisted selection. In this literature review, we discuss the most promising and well-described candidates and their associations with selected beef production traits.

  • Improved efficiency in the use of natural resources, pragmatic production systems and environmental sustainability, justified by the need for improved land use systems and increased productivity, are discussed in the context of Asian integrated systems, diversification, and issues of sustainability. The importance of these are reflected by serious inadequate animal protein production throughout Asia, where available supplies cannot match current and projected human requirements up to 2050. Among the ruminant production systems, integrated tree crops-ruminant production systems are grossly underestimated and merit emphasis and expansion. As an example, integrated oil palm- based system is an important pathway for integration with ruminants (buffaloes, cattle, goats and sheep), and provides the entry point for development. The importance and benefits of integrated systems are discussed, involving animals with annual and perennial tree crops, integration with aquaculture, the significance of crop-animal interactions, stratification of the systems, production options, improved use of forages and legumes, potential for enhanced productivity, implications for improved livelihoods of the rural poor and the stability of farm households. The advances in research and development in South East Asia highlight demonstrable increased productivity from animals and meat offtakes, value addition to the oil palm crop, sustainable development, and distinct economic impacts. The results from 12 out of a total of 24 case studies concerning oil palm over the past three decades showed increased yield of 0.49-3.52 mt of fresh fruit bunches (FFB)/ha/yr; increased income by about 30%; savings in weeding costs by 47- 60% equivalent to 21-62 RM/ha/yr; and an internal rate of return of 19% based on actual field data. The results provide important socio-economic benefits for resource-poor small farmers. Potential increased offtakes and additional income exist with the integration of goats. Additionally, the potential for carbon sequestration with tree crops is an advantage. The reasons for low adoption of the syatems are poor awareness of the potential of integrated systems, resistance by the crop- oriented plantation sector, and inadequate technology application. Promoting wider expansion and adoption of the systems in the future is linked directly with coherent policy, institutional commitment, increased investments, private sector involvement, and a stimulus package of incentives.

  • 이 연구는 DDC를 사용하는 한국도서관에서 종교류를 재전개하기 위한 시안을 제시하기 위한 것이다. 이를 위하여 우선 DDC 의 종교류에 마련된 임의규정의 발전 과정과 문제점을 살펴보고, DDC 종교류의 임의규정은 단일종교가 그 나라에서 대표성을 갖는 경우에 대비한 것으로, 한국과 같이 다수의 종교가 공존하는 나라의 경우에는 이를 적용하기가 어렵다는 점을 밝혔다. 이 연구에서 제시한 재전개안의 특징은 DDC 의 기본적인 체계와 배열순서를 유지하면서도, 한국의 실정에 맞도록 불교와 동양의 종교를 강조할 수 있도록 한 점이다. 이를 위해 DDC 원안의 220-280의 7개 강에 전개된 기독교를 220 하나의 d로 축소하였고, 230부터 270에는 불교를 비롯한 그 밖의 종교를 배정하여, 여러종교간의 균형을 유지하였고, 특히 동양3국의 주요종교를 상위에 배치시켰다. 아울러 이 안에서는 불교와 동양종교, 한국종교를 강조하고자 할 경우에 대비한 별법(別法)도 제시하였다.

  • The animal industry must be environmentally sound to ensure its long-term sustainable growth. Livestock wastes mostly manure, can be a valuable resource as well as a potential hazard to environment. The first option of manure management is developing an 'environmentally sound' feeding program and feeds so there are less excreted nutrients that need to be managed. Once the manure is produced it can be best utilized as a fertilizer of a soil conditioner. In many countries the amount of manure that can be spread on land depends on the nutrient requirements of the crop being grown. The laws specify maximum application rates and not animal stocking rates. Farmer who reduce the N and P component of manure can release pressure on the environment without having to reduce the number of animals. There are alternative system for housing and manure treatment which generate manure that are easier to handle and have less pollutants or more economic value. Treated animal waste may also be used as a feedstuff or fuel source. Most of the options of waste management result in increased costs to implement. It is necessary to assess the economics in order to find an acceptable compromise between the increased costs and the benefit to the environment. Animal welfare is also becoming more and more of an issue and it will lead to systems where animals are kept in less confined environment. The new system will have a great impact in the waste management system in the future.

  • Diagnostic and therapeutic strategies of prostate cancer may largely influenced by patients' age at presentation. This study is aimed to evaluate the characteristics, diagnostic and treatment strategies in prostate cancer patients in our centres. A cross-sectional analytic study of prostate cancer data in two main referral cancer centres, Cipto Mangunkusumo General Hospital and Dharmais National Cancer Centre from 1995-2010, was therefore performed. Patients were divided into 2 sub-populations; below 60 years (younger patients) and 75 years old and above (older patients). PSA levels, diagnostic modalities, Gleason score and therapeutic options were analysed for both and compared using bivariate analysis. 152 patients were <60 years and 210 were ${\geq}75$ years. There was no statistical difference in mean PSA level (797.9ng/mL vs 345.3 ng/mL, respectively; p>0.05) and diagnosis was made by biopsy in majority of patients in both groups (68.2% and 71.6% in younger and older groups respectively). Most presented with an advanced disease stage (65.1% and 66.0%, respectively) and there was no statistically significant difference in mean Gleason scores f (8.1 vs 7.7; p>0.05). Primary androgen deprivation therapy (PADT) was the main treatment for overall patients (48.0% and 50.7%, respectively). Radiotherapy and radical prostatectomy are the main therapeutic modalities for younger patients with local and locally advanced disease (39.6% and 35.4% respectively), while the majority of older patients with the same disease stage were treated with radiotherapy and PADT (45.8% and 39.0% respectively). Differences observed in treatment modalities were statistically significant (p<0.0003). We conclude that there is no difference in disease clinical aggressiveness of the two groups but significant differences were observed in therapeutic strategies utilised with younger and older patients.

  • Background: Breast cancer is the most frequent type of cancer among women in the world and the most common cause of deaths from cancer in females. In Turkey, breast cancer comes first in the list of the most frequent ten cancer types seen in women. As the incidence rate of breast cancer is high, many women having breast cancer in the family experience the breast cancer at secondhand. This study was carried out in an attempt to determine the information and support needs of women whose first-degree relatives have breast cancer and to what extent these needs are met. Methods: The research sample consisted of 156 women. Questionnaire Form and Information and Support Needs Questionnaires were used as the data collection tools. Results: Information need score averages ($x^-:3.72{\pm}0.19$) of women included in the research sampling were found to be higher than their score averages of support needs ($x^-:3.24{\pm}0.41$). Conclusion: Information needs which were indicated by women as very important were related to treatment, symptoms of breast cancer and breast self examination (BSE), while support needs which were indicated by women as very important were learning how to perform BSE, women's anxiety for themselves and their relatives regarding breast cancer and having their breasts examined by a health professional. It is recommended that nurses and other medical staff should give information to women whose first-degree relatives have breast cancer about the disease, its etiology, scanning, diagnosis, treatment options and protection as well as prevention.

  • Background: Male breast cancer (MBC) is a rare disease that accounts for less than 1% of all cancers in men and less than 1% of all diagnosed breast cancers. In this study, we retrospectively evaluated the clinicopathological features, treatment options and overall survival in Kurdish MBC cases. Materials and Methods: Seventeen MBC were referred to Department of Radiation Oncology in Imam Reza Hospital, Kermanshah, Iran, between 2010 and 2016. Immunohistochemical analysis was performed for ER, PR and Her2 biomarkers and FISH for those with Her2 2+. Median follow-up period was 30 months (2-65 months). We excluded from the study patients who did not have follow-up after initial diagnosis. Treatment methods were chemotherapy, radiotherapy, hormonal therapy, target therapy and palliative care. Survival was estimated by the Kaplan Meier method (Prism 5). Results: The mean age at diagnosis was $49.24{\pm}17$ years (range, 24-85 years). Grade II was the most grade in MBC (65%). Fourteen patients (82%) had invasive ductal carcinoma, one (6%) had ductal carcinoma in situ and 2 (12%) had invasive papillary. ER, PR and Her2 were significantly positive in 14/17, 8/17 and 2/17 cases, respectively. The treatment included modified radical mastectomy for most patients. Chemotherapy with TAC and CEF regimens was delivered to 15/17 cases. Tamoxifen therapy was delivered to 14/17 cases. Three stage IV patients received Avestin and two with Her2 3+ were given Trastuzumab (Herceptin). Patients received adjuvant radiotherapy following surgery and chemotherapy. The site of metastasis was the bone in 2 cases, lung in 1 case and liver in 1 case. Zoledronic acid (Zometa) was prescribed for patients with bone metastasis. Five-year overall survival rate was 64%. Conclusions: MBC is rare. Thus, we need larger studies are in collaboration with several research centers in the field of breast cancer. ER positive, grade II of invasive ductal carcinoma, stage II and right side happened more with MBC. Overall survival is similar to other studies.

  • Background: Esophageal cancer is one of the most serious malignancies. Due to the aggressive nature of this cancer, the prognosis is poor. A network meta-analysis with simultaneous comparison of multiple treatments can help determine better treatment options that have higher effects on overall survival of patients with lower adverse events. The aim of this review is to simultaneously compare efficacy and adverse events of treatment interventions for esophageal cancer. Materials and Methods: In this review, only randomized control trials (RCT) will be considered for network meta-analysis. All international electronic databases including Medline, Web of Sciences, Scopus, Cochran's library, EMBASE and Cancerlit will be searched to find randomized control trials which compared two or more treatment interventions for esophageal cancer. A network plot will be drawn for visual representation of all available treatment interventions. Bayesian approach will be used to combine the direct and indirect evidence. Treatment effects (e.g. hazard ratio for time to event outcomes, risk ratio for binary outcomes, and rate ratio for count outcomes with 95% credible interval) will be reported. Moreover, cumulative probability of the treatment ranks will be reported using the surface under the cumulative ranking (SUCRA) graphs. Consistency assumption will be assessed by the loop-specific and design-by-treatment interaction approaches. Conclusions: The results of this study may be helpful for the patients, clinicians and health policy makers in selecting treatments that have the best effect on survival and lowest adverse events.

  • Gastric cancer (GC) is a major health problem worldwide and is one of the ten most commonly diagnosed cancers in Jordan. GC is usually diagnosed at late aggressive stages in which treatment options are limited. Recently, heat shock proteins (HSPs) were found to be overexpressed in a wide range of malignancies have been considered as promising candidate biomarkers for GC. The aim of this study was to investigate pathogenic roles of a panel of cytosolic HSPs including HSP90, HSP70, HSP60 and HSP27 in GC. Immunohistochemistry was used to assess the level of expression of these proteins in archived tumor samples (N=87) representing various pathological characteristics of GC. HSP90, HSP60 and HSP27 were expressed abundantly in gastric tumors. On the other hand, HSP70 was reduced significantly and also found to be associated with Helicobacter pylori infection in tissues collected from GC patients. Furthermore, HSP27 was found to be associated with the level of differentiation. Our findings indicate a role of HSP70 as a potential prognostic biomarker, patients harboring positive HSP70 expression displaying worse disease free survival than those with negative HSP70 expression. Differential expression of HSPs may play crucial roles in the initiation and progression of GC, and could be exploited as future therapeutic targets.

  • Background: The aim of this study was to investigate whether electrochemotherapy is a clinically and cost-effective treatment option against skin tumors. Materials and Methods: We performed an analysis of the current literature based on database searches in PubMed/MEDLINE and we included articles till July 2012. Terms used for the search were 'electrochemotherapy', 'skin cancer', 'recurrence', and 'cutaneous and subcutaneous tumors'. Only papers published in English were included. In addition, we performed an analysis of the cost effectiveness of the method. Results: The combination of physics and chemistry is the foundation for electrochemotherapy and its efficacy, independent of the tumor histology. Clinical data showed that ECT is well tolerated and can be used in difficult cases without other available treatment options. The analysis also showed that the treatment is feasible and cost-effective. Conclusions: Electrochemotherapy is a clinically efficient safe and cost-effective treatment and clinicians should not hesitate to use it as alternative therapeutic modality or as palliative treatment.
