Human-wildlife conflicts, such as crop-raiding, increase as people expand their agricultural activities into wildlife habitats. Crop-raiding can reduce tolerance toward species that are already threatened, whereas potential dangers posed by conflicts with large-bodied species may also negatively influence local attitudes. Across Asia, wild pigs and primates, such as macaques, tend to be the most commonly reported crop raiders. To date, reports of crop-raiding incidents involving great apes have been less common, but incidents involving orangutans are increasingly emerging in Indonesia. To investigate the interplay of factors that might explain attitudes toward crop-raiding by orangutans (Pongo abelii), focal group discussions and semi-structured interviews were conducted among 822 farmers from 2 contrasting study areas in North Sumatra. The first study area of Batang Serangan is an agroforest system containing isolated orangutans that crop-raid. In contrast, the second area of Sidikalang comprises farmlands bordering extensive primary forest where orangutans are present but not reported to crop-raid. Farmers living in Batang Serangan thought that orangutans were dangerous, irrespective of earlier experience of crop-raiding. Farmers placed orangutans as the third most frequent and fourth most destructive crop pest, after Thomas' leaf monkey (Presbytis thomasi), wild boar (Sus scrofa), and long-tailed macaque (Macaca fascicularis). Although most (57%) farmers across both study areas were not scared of wildlife species, more than a quarter (28%) of the farmers' feared orangutans. Farmers in Batang Serangan were generally more tolerant toward crop-raiding orangutans, if they did not perceive them to present a physical threat. Most (67%) Batang Serangan farmers said that the local Forestry Department staff should handle crop-raiding orangutans, and most (81%) said that these officials did not care about such problems. Our results suggest that efforts to mitigate human-orangutan conflict may not, per se, change negative perceptions of those who live with the species, because these perceptions are often driven by fear. © 2010 Wiley-Liss, Inc.

Development's Millennium Development Goal (MDG) on reducing infectious diseases including HIV / AIDS. The program still faces many obstacles, because the problem of HIV / AIDS isrelated to lack of knowledge and understanding of the community. The resistance of the socio-cultural aspects in counselling is happening, especially in Aceh province as religion-based province. In connection with the program to improve public knowledge in the prevention of HIV / AIDS, communication concept developed should always pay attention to the closeness between the aspects of culture, psychological, and social. This study aims to determine the appropriate method of communication in the prevention of HIV / AIDS in North Aceh District by religious leaders (religious teacher) and health counselors. This study is a quasi-experimental (quasi-experimental study pre-test and post-tests design). This study was conducted in North Aceh District covers three districts and each sub-district consists of two villages namely Lhoksukon Subdistrict (Desa Ara Abe and Village Nga), Dewantara subdistrict (Desa Paloh Lada and Village Bangka Jaya), Seunuddon districts (Village Ulee Rubeek West and the village of Ulee Rubeek Timu). This research has been conducted in April-May 2015. Thepopulations were used as much as 14.020 couples of reproductive age and the samples were obtained using a sample size of at least 132, according Lemeshow in every village so that the entire sample of 492 couples of childbearing age. Data were analysed using a pre-test and posttest gain index, while hip dissertation test using Mann-Whitney U. Based on the results showed that the empirically proven that the model of health education approach method with religious leaders (religious teacher) proved more effective than the model of health education undertaken by health counsellors. There are differences in the level of knowledge about the prevention of HIV / AIDS significantly in women of reproductive after the health education provided by religious teacher and health counsellors, (p = 0.001 <0.05). Increased knowledge score Aged Women of Reproductive about the prevention of HIV / AIDS are taught by religious teacher was significantly higher than the score of knowledge of women of reproductive who receive counselling by health counsellors women of reproductive are more enthusiastic to follow counselling that delivered by religious teachercompare to the counselling which delivered by health counsellors. Proximity psychological, emotional, social and culture among women of reproductive age with religious teacher. This is because the religious teacher can customize the material submitted by the communicant sociopsychologic. During this time the role of religious teacher is more on improving the quality of faith and morality, while the implementation in the prevention of various diseases that can be affected the public. It is suggested that the religious teacher should be empowered to educate the public about health through religious approach by using effective communication methods to improve public knowledge.

Acetolactate synthase (ALS)-inhibiting herbicide resistance is common in Raphanus raphanistrum (wild radish) populations across the Western Australian (WA) grain belt. This study investigates the molecular and biochemical basis of ALS herbicide resistance in five R. raphanistrum populations. Five known ALS herbicide resistance-endowing mutations (Pro-197-Ala, Pro-197-Thr, Pro-197-Ser, Asp-376-Glu and Trp-574-Leu) were identified, and their resistance spectrum to ALS-inhibiting herbicides was determined using purified populations individually homozygous for each mutation (except for Pro-197-Ala). Plants homozygous for ALS mutations at Pro-197 were found to be cross-resistant to ALS-inhibiting sulfonylurea (SU) and triazolopyrimidine (TP) herbicides, while plants homozygous for Trp-574-Leu were resistant to SU, TP and imidazolinone (IMI) ALS herbicide classes. The Asp-376-Glu mutation is reported here for the first time in R. raphanistrum populations and characterised at both the whole-plant and enzyme level. Plants homozygous for Asp-376-Glu were highly resistant to SU and TP herbicides, based on LD 50 R/S ratios (>130 and 128 respectively) and I 50 R/S ratios (170 and >110 respectively). In contrast, these plants were moderately resistant to the IMI imazamox (LD 50 R/S ratio of 8, I 50 R/S ratio of 3) and imazethapyr (I 50 R/S ratio of 8) and susceptible to imazapyr (I 50 R/S ratio of 0.76). A novel observation in this study is that resistance of homozygous Glu-376 plants is associated with a remarkable growth reduction in the presence of the ALS herbicides tested, making early resistance diagnosis and management difficult. © 2012 The Authors.

In Indonesia, the Central Bureau of Statistics of North Sumatra Province (2011), estimates that in 2010 the infant mortality rate of 24.5 per 1,000 live births. This figure decreased when compared to the previous year at 26.90 per 1,000 live births. There are several factors influencing the reduction in infant mortality, among others, the availability of various facilities or accessibility factors and health services from skilled medical personnel and the willingness of people to change the traditional life to the norm of modern life in the field of health. this study aims to explore how families with Mandailing culture care for pregnant mother in in term of nutritional support. Informants in this study are Mandailing Natal community. This study found that If there are health workers or health care in they place, pregnant mother will come to check their condition and their nutritional status at health workers during childbirth although later they are more happy assisted by traditional birth attendants or village shaman, it can reduce the complications or problems that the pregnant women who will ultimately reduce maternal mortality and infant mortality rate. Mandailing Natal society is a society that is not closed to new information, the community here is relatively easy in receiving information or a new thing, it's just that sometimes less precise methods of delivery that makes people not obey the things delivered. To improve community health status Mandailing Natal especially pregnant mother and childbirth it is advisable: That the government is aggressively disseminating health programs so that the public is more familiar with the health programs in a way reproduce health workers, especially midwives who will assist communities in improving the health of pregnant mothers especially in term of their nutrition and health services in Mandailing Natal to be more proactive in providing community especially related information to the health of pregnant mothers.

to investigate the safety and effectiveness of dose TU+DMPA hormones in developing potential male contraceptives. suppression of rat sperm concentration through increased apoptotic germ cells by in vivo administration of a long-acting androgen composed of a combination of testosterone undecanoate (TU) and depot medroxyprogesterone acetate (DMPA) was performed. Adult Sprague-Dawley rats received 2.5 mg TU every 6 week and 1.25 mg DMPA every 12 week for 60 week, a regimen known to rapidly reduce testosterone production by the testes and produce azoospermia within 12 week. Sperm concentration data were log transformed before analysis. Results are expressed as the mean±SEM. ANOVA, followed by post hoc test was used to determine differences across time and phase. T test was employed to determine differences between two groups. apoptosis revealed significant increase in apoptotic germ cells (80% when rats were administered with TU+DMPA. Apoptotic germ cells can be found in several spermatogonia (20%), spermatocytes (30%), and spermatids (50%). dose TU+DMPA hormones may be a safe and effective way to develop potential male contraceptives.
