Abstract: Foxtail millet ( Setaria italica (L) P Beauv) falls on the category of underutilized crops in Nepal and mainly cultivated in Karnali region of the country. It is hardy crop and considered as one of the potential crops for future food security with respect to climate change. Five accessions of Nepalese foxtail millet were purposefully selected for evaluation of the agro-morphological characteristics. Foxtail landraces from Dolpa, Mugu, Bajura, Bajhang and Lamjung districts of Nepal were evaluated at Khumaltar, Lalitpur, Nepal during 2010. The plot size was 1m 2 and there were five samples. Days to heading and days to maturity varied from 33-56 and 59 to 87 days after germination respectively. Similarly, flag leaf length/breadth ratio, flag leaf sheath length, ligule length, peduncle length, peduncle exertion and plant height varied from 3.84-10.90, 5.47-9.84 cm, 0.1-0.2 mm, 10-22.57 cm, 2.7-13.58 cm and 41.67-120 cm, respectively. Fruit and apiculus color varied from straw to black. All accessions were actively growing with very slight lodging. Similarly, the thousand grain weight varies from 1.064 g to 2.172 g. This variation is useful in foxtail millet breeding program. Similarly, the significant correlation between thousand kernel weight and total basal tiller (r=-0.975) showed that foxtail millet lines with low tillering ability is better for yield enhancement.

Agronomy Journal of Nepal , 2013, DOI: 10.3126/ajn.v3i0.8982
Abstract: The experiment was conducted with four levels of nitrogen (40, 80,120 and 160 kg/ha) and 3 different cultivars (Prithivi hybrid), Masuli (HYV) and Sunaulo Sugandha (Aromatic).RMSE value (747.35 kg/ha, 1.106 days, 2.58 days and 0.004 kg/ha) and D-stat value (0.793, 0.99, 0.99 and 0.633) for grain yield, anthesis days, maturity days, and individual grain weight respectively. The objective of this study was to identify whether CSM-CERES-Rice model can be used in Nepalese condition and to evaluate the sensitivity of model with impact of climate change on rice production. Eight different climate scenarios were built by perturbing maximum and minimum temperature (± 4°C), CO2 (± 20ppm), solar radiation (±1MJ/m2/day) using interactive sensitivity analysis mode in DSSAT. Among the scenario evaluated, temperature (± 40°C), CO2 concentration (+20 ppm) with change in solar radiation (±1MJ m-2 day-1) resulted maximum increase in yield (by 62, 41 and 42%) under decreasing climatic scenarios and sharp decline in yield (by 80, 46 and 40%) was observed under increasing climate change scenarios, in Prithivi, Masuli and Sunaulo Sugandha cultivars respectively.Not surprisingly, increasing yield by (48, 25 and 27 %) and decrease in yield by(77, 41 and 34) by perturbing only maximum and minimum temperature by (± 4) shows that the temperature is most sensitive for yield potentiality of cultivars than other. CERES-Riceversion 4.0 was well calibrated in Chitwan Nepal condition. The model applications show that model could be a tool for precision decision-making. There was variation in yield in response to the change in climatic scenario in the study. RMSE value (747.4 kg/ha, 1.11days, and 2.58 days), and d-stat (0.79, 0.99 and 0.99) for grain yield, anthesis, and maturity days confirm the possibility of CERESRiceuse in Nepalese agriculture. The finding showed that there was sharp decrease in rice yield due to change in temperature, CO2 and solar radiation. Climatic scenario developed by CERES-Rice model in sensitivity analysis resulted yield reduction up to 80%. Among the cultivar, hybrid rice shows more vulnerability with climate change. Decrease in yield were mainly associated with lowering growth duration along with increasing temperature, where as there is very less counter effect of increasing carbon dioxide concentration and solar radiation.
On-demand sedation with propofol for colonoscopy—A prospective pilot study of the influence on short-term memory, psychomotor function and postural stability*  [PDF]

Abstract: Background: After sedated colonoscopy, patients are discharged on the basis of their subjective judgment that they have recovered, corroborated by the nursing staff. The aim of this study was to assess objectively whether patients were in fact fully recovered at the time of discharge, and to demonstrate whether the methods of testing applied could detect any influence of sedation on short-term memory, psychomotor function and postural stability. Methods: Twenty-two patients were investigated. At the beginning of the procedure, a defined bolus of propofol/alfentanil was given intravenously. During the procedure, an additional bolus was injected one or more times as requested by the patient. After colonoscopy, the patients stayed in the recovery room until the patients judged that they had recovered completely, which was also the judgement of the nursing staff at that time. Before colonoscopy and again before discharge, tests were performed of short-term memory, psychomotor function and postural stability (balance). Results: A positive correlation was found between the duration of colonoscopy and the amount of sedative given (p < 0.03). No differences in short-term memory or postural control were found when measurements obtained before and after colonoscopy were compared. Reaction time was prolonged significantly after colonoscopy (p < 0.01), which was mainly due to prolongation of perception time (p < 0.003). No correlation was found between the observed reduction in psychomotor function and the amount of sedative given. Conclusions: The introduction of ultrashort-acting sedative and hypnotic agents has facilitated out-patient colonoscopy. However, although they feel that they have recovered fully, some patients are still affected by the sedative at the time of discharge, as demonstrated by tests of short-term memory, reaction time and postural stability.

Regulation of human breast stem cells

Abstract: We employed several complementary approaches to identify putative stem cell markers, to characterise an isolated stem cell population and to relate these to cells expressing ERα. ERα-positive cells were found to coexpress the putative stem cell markers p21CIP1 and Msi-1. Human breast epithelial cells with Hoechst dye-effluxing 'side population' (SP) properties characteristic of mammary stem cells in mice were demonstrated to be undifferentiated cells by lack of expression of myoepithelial and luminal epithelial membrane markers. These SP cells were sixfold enriched for ERα-positive cells and expressed several-fold higher levels of the ERα, p21CIP1 and Msi1 genes than non-SP cells. In contrast to non-SP cells, SP cells formed branching structures in matrigel which included cells of both luminal and myoepithelial lineages. The data suggest a model where scattered ERα-positive cells are stem cells that self-renew through asymmetric cell division and generate patches of transit amplifying and differentiated cells.In recent studies we have been investigating breast cancers for the presence of a stem cell population. Using a nonadherent culture method analogous to neurosphere culture that enriches for neural stem cells, we have demonstrated that breast cancer cell lines and primary tumours contain a self-renewing population that is highly regulated by the Notch receptor signaling pathway. Inhibitors of this pathway could represent a new therapeutic modality in breast cancer, perhaps through combination with current treatments.In order to discover novel pathways that regulate stem cell self-renewal, we have applied functional genomics using an RNAi library targeting ~8,000 genes involved in cancer. This has revealed the importance of several pathways not previously associated with stem cell self-renewal. These pathways may represent novel targets for breast cancer therapy aimed at the breast cancer stem cells that survive conventional therapies.
The role of foraging (harvester) ants, Messor cephalotes, in land degradation in Meserani area Monduli District, Tanzania

Abstract: Meserani is a semi arid area in Monduli District in north east Tanzania that is prone to land degradation in terms of vegetation and soil degradation due to natural and anthropological factors. For a number of years the local community including extension officers had suspected that in certain locations of Meserani area bare lands, apart from grazing and farming activities were also created by grazing insects. The main objective of this paper was firstly, to identify the type of grazing insects that were creating bare lands, hence land degradation. Land degradation in this context is taken to mean the removal of herbaceous vegetation caver. Secondly, to determine the extent in which grazing insects are contributing to land degradation in the area. The harvester ants of species Messor cephalotes, Emmery were identified as the main insects that were foraging herbaceous vegetation cover thus creating bare lands in some of the locations in the study area. Areas with high intensity of human activities in terms of framing and grazing had more bare lands created by ants than the fallow or stony areas. Therefore in the Meserani harvester ants just like grazing or farming activities were contributing to land degradation through the creation of bare lands.

Abstract: suring safe access to medication for palliative care while preventing prescription drug abuse: innovations for American inner cities, rural areas, and communities overwhelmed by addiction Commentary (3791) Total Article Views Authors: Francoeur RB Published Date September 2011 Volume 2011:4 Pages 97 - 105 DOI: http://dx.doi.org/10.2147/RMHP.S24068 Richard B Francoeur School of Social Work, Adelphi University, Garden City, NY, USA; Center for the Psychosocial Study of Health and Illness, Columbia University, New York, NY, USA Abstract: This article proposes and develops novel components of community-oriented programs for creating and affording access to safe medication dispensing centers in existing retail pharmacies and in permanent or travelling pharmacy clinics that are guarded by assigned or off-duty police officers. Pharmacists at these centers would work with police, medical providers, social workers, hospital administrators, and other professionals in: planning and overseeing the safe storage of controlled substance medications in off-site community safe-deposit boxes; strengthening communication and cooperation with the prescribing medical provider; assisting the prescribing medical provider in patient monitoring (checking the state prescription registry, providing pill counts and urine samples); expanding access to lower-cost, and in some cases, abuse-resistant formulations of controlled substance medications; improving transportation access for underserved patients and caregivers to obtain prescriptions; and integrating community agencies and social networks as resources for patient support and monitoring. Novel components of two related community-oriented programs, which may be hosted outside of safe medication dispensing centers, are also suggested and described: (1) developing medication purchasing cooperatives (ie, to help patients, families, and health institutions afford the costs of medications, including tamper- or abuse-resistant/deterrent drug formulations); and (2) expanding the role of inner-city methadone maintenance treatment programs in palliative care (ie, to provide additional patient monitoring from a second treatment team focusing on narcotics addiction, and potentially, to serve as an untapped source of opioid medication for pain that is less subject to abuse, misuse, or diversion).
