American Journal of Agricultural Economics, EarlyView.Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

POISONING WITH GAMMA-HYDROXYBUTYRATE, GAMMA-BUTYROLACTONE AND 1.4-BUTANDIOL
Zdravniški Vestnik, 2002 Background. Gamma-hydroxybutyrate (GHB) is a popular recreational drug. GHB overdose typically presents with decreased level of consciousness, miosis, bradycardia, respiratory depression and death.

American Journal of Agricultural Economics, EarlyView.Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Latin American Journal of Aquatic Research, 2012 Cultivation of cyanobacterium Arthrospira sp. has been developed in many countries for the production of proteins, pigments and other compounds. Outdoor mass cultures are often affected by biological contamination, drastically reducing productivity as far as bringing death. This study evaluates the control of Branchionus sp. and Amoeba sp.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods
Advanced NanoBiomed Research, EarlyView.Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

INSTRUMENTAL MEASUREMENT OF KNEE LAXITY IN ANTERO-POSTERIOR DIRECTION
Zdravniški Vestnik, 2004 Background. A magnitude of clinical tests (like Lachman test) are used to diagnose antero-posterior knee instability. They are easy to preform but they are very subjective. An experienced practitioner is often required.

Angewandte Chemie, EarlyView.Eine Genomanalyse zeigte das Vorkommen zahlreicher Terpensynthasen des bakteriellen Typs in Springschwänzen. Vier Enzyme aus Sinella curviseta wurden funktionell charakterisiert, was zur Isolierung mehrerer Verbindungen führte, darunter Sinellenether, der erste identifizierte Diterpenether einer Terpensynthase mit einem neuartigen Grundgerüst.

Angewandte Chemie International Edition, EarlyView.A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.
