Südkorea: Ein Apfel für acht Franken

In Südkorea ist gesundes und schönes Obst viel wert. Das fördert den Bioanbau, erfordert aber auch guten Pflanzenschutz. Daher steht Südkorea mit FiBL-Forschenden im Austausch

Bovine tuberculosis and brucellosis prevalence in cattle from selected milk cooperatives in Arsi zone, Oromia region, Ethiopia

Bovine tuberculosis (BTB) and bovine brucellosis are two important milk-borne zoonoses that have been shown to be prevalent to various degrees in Ethiopian cattle. The study was carried out in four Woredas (districts) around Asella town, Arsi Zone between October 2011 and March 2012 and included 318 small-holders in 13 dairy cooperatives that marketed the delivered milk. The aims of the study were i) to assess the prevalence of the two diseases in cattle in a cross-sectional study, ii) to assess potential risk factors of BTB and brucellosis to humans as well as the knowledge-attitude-practice (KAP) among these farmers towards these diseases.; BTB testing using the comparative intradermal skin test (CIDT) was done on 584 milking cows, out of which 417 were serologically tested for brucellosis using the Rose Bengal Plate Test and reactors confirmed with an indirect ELISA test (PrioCHECK®). The individual animal prevalence was 0.3% (95% CI 0.1% to 1.3%) for BTB, 1.7% (95% CI 0.8% to 3.5%) for brucellosis and 8.9% (95% CI 6.8% to 11.5%) for MAC (Mycobacterium avium complex). Of the 13 milk cooperatives, two had at least one positive BTB reactor and five had animals positive for brucellosis. Cross-breeds accounted for 100% and 71.4% of the BTB and brucellosis reactors respectively. For both diseases, there were prevalence variations depending on Woreda. No animal was concomitant reactor for BTB and brucellosis. Raw milk was consumed by 55.4% of the respondents. 79.2% of the respondents reported touching the afterbirth with bare hands. The latter was fed to dogs in 83% of the households. One cow among the herds of the 130 interviewees had aborted in the last 12 months. Among the interviewees, 77% stated knowing tuberculosis in general but 42 out of the 130 respondents (32.3%) did not know that BTB was transmitted by livestock. Less than half (47.7%) of the respondents knew about brucellosis.; Low prevalence of both diseases reflected the potential for the area to compete with the growing milk demand. The authors discussed the possible control strategies for the area

Status Report on the Application of Integrated Approaches to Water Resources Management 2012

UN-Water produced a status report regarding the progress of water resources management in several countries as well as possible outcomes and impacts of integrated approaches. It is also based on a 2011 UN-Water survey sent to the governments of all UN member states and a series of complementary interviews in 30 representative countries

GABAA Increases Calcium in Subventricular Zone Astrocyte-Like Cells Through L- and T-Type Voltage-Gated Calcium Channels

In the adult neurogenic subventricular zone (SVZ), the behavior of astrocyte-like cells and some of their functions depend on changes in intracellular Ca2+ levels and tonic GABAA receptor activation. However, it is unknown whether, and if so how, GABAA receptor activity regulates intracellular Ca2+ dynamics in SVZ astrocytes. To monitor Ca2+ activity selectively in astrocyte-like cells, we used two lines of transgenic mice expressing either GFP fused to a Gq-coupled receptor or DsRed under the human glial fibrillary acidic protein (hGFAP) promoter. GABAA receptor activation induced Ca2+ increases in 40–50% of SVZ astrocytes. GABAA-induced Ca2+ increases were prevented with nifedipine and mibefradil, blockers of L- and T-type voltage-gated calcium channels (VGCC). The L-type Ca2+ channel activator BayK 8644 increased the percentage of GABAA-responding astrocyte-like cells to 75%, suggesting that the majority of SVZ astrocytes express functional VGCCs. SVZ astrocytes also displayed spontaneous Ca2+ activity, the frequency of which was regulated by tonic GABAA receptor activation. These data support a role for ambient GABA in tonically regulating intracellular Ca2+ dynamics through GABAA receptors and VGCC in a subpopulation of astrocyte-like cells in the postnatal SVZ

The Effectiveness of Coenzyme Q1 and Q10 in Mitigating Myocardial Reperfusion/Ischemia (MI/R) Injury

Mitochondria may be a principle source of oxidative stress causing MI/R injury. Coenzyme Q10 (CoQ10) is essential for electron transport in normal mitochondria, has antioxidant properties but its bioavailability is likely reduced due to oxidative stress during MI/R. Coenzyme Q1 (CoQ1) is a derivative of CoQ10, but is a more potent antioxidant than CoQ10 due to a shorter isoprene chain. We hypothesize that CoQ1 will exhibit better cardioprotective effects during MI/R. CoQ1 (MW=250 g/mol; 20 μM, n=5) and CoQ10 (MW=863 g/mol; 20 μM, n=5) were given at reperfusion in isolated rat hearts subjected to I (30 min)/R (45 min). We found that MI/R hearts (n=7) and MI/R+DMSO hearts (n=4) (0.2% DMSO was used to solubilize CoQ1 and CoQ10) exhibited significantly compromised cardiac contractile/diastolic pressures and coronary flow during reperfusion compared to those of sham hearts (n=5). By contrast, the final left ventricular developed pressure was significantly improved by CoQ1 treatment (56.0±5.3 mmHg), but not CoQ10 treatment (38.4±8.6 mmHg), when compared to that in MI/R hearts (33.6±6.2 mmHg) and MI/R+DMSO hearts (36.4±9.7 mmHg) (p\u3c0.05). Similarly, the final peak of the firstderivative of left ventricular pressure was significantly higher in CoQ1 treatment (1294.2±104.6mmHg/s), but not CoQ10 treatment (770.6±120.1 mmHg/s), when compared to that in MI/R hearts (700.6±134.7 mmHg/s) and MI/R+DMSO hearts (and 741.5±168.6 mmHg/s) (p\u3c0.05). CoQ1 and CoQ10 treated hearts showed no improvement on diastolic pressure and coronary flow compared to the controls. Moreover, infarct size was reduced by CoQ1 treatment (25±3%) and CoQ10 treatment (29±4%) compared to that in untreated MI/R (44±6%) and MI/R+DMSO (35±3%). In summary, our preliminary results indicate that CoQ1 was more effective than CoQ10 in restoring post-reperfused cardiac contractile function, but not infarct size during MI/R
