The plant defensin NaD1, from Nicotiana alata, has potent antifungal activity against a range of filamentous fungi including the two important cotton pathogens, Fusarium oxysporum f. sp. vasinfectum (Fov) and Verticillium dahliae. Transgenic cotton plants expressing NaD1 were produced and plants from three events were selected for further characterization. Homozygous plants were assessed in gre...

0 → Ker f1 → Ker f2 → Ker f3 → Coker f1 → Coker f2 → Coker f3 → 0, where f = (f1, f2, f3) is a suitable homomorphism between short exact sequences in A? This question is an instance of a more general problem. Let D(A) be the derived bounded category of A. We ignore the possible set-theoretic difficulties mentioned in [5, §2.2], because in what we intend to do with D(A) here they do not play any...

Biotechnology has almost unlimited potential to change our lives in very exciting ways. Many of the chemical reactions that produce these products can be fully optimized by performing them at extremes of temperature, pressure, salinity, and pH for efficient and cost-effective outcomes. Fortunately, there are many organisms (extremophiles) that thrive in extreme environments found in nature and ...

Phosphatidylserine (PS) externalization is a marker for the nucleated cell apoptosis, and refers cellular activation rather than apoptosis in platelets. On the other hand, several similarities exist between platelet activation and apoptosis in nucleated cells. Herewith we investigated the relationship between platelet activation and platelet apoptosis. Platelets isolated from fresh blood of 22 ...

The methodology described in this article was developed to transcend the limitations of both approaches. Its goal is to use existing data to identify small areas with high levels of adolescent childbearing. The method is an active approach to identify what can be defined as “hot spots” for adolescent births, even when they are located in counties or communities where adolescent births are not c...

Tooth root formation is initiated by the elongation of Hertwig’s epithelial root sheath (HERS). HERS cells are widely accepted to control root formation, but the mechanisms regulating HERS growth have not been elucidated. To solve this problem, we have established a new culture method for postnatal mouse mandibular molars and, using it, examined the role of insulin-like growth factor-I (IGF-I) ...

RAPID EYE MOVEMENT (REM) SLEEP BEHAVIOR DISORDER (RBD) IS A PARASOMNIA CHARACTERIZED BY DREAM-ENACTING BEHAVIORS RELATED TO LOSS OF the normal generalized skeletal muscle atonia during REM sleep1,2. RBD may be idiopathic or associated with neurodegenerative diseases such as Parkinson’s disease3, multiple system atrophy4, dementia with Lewy bodies5, Machado-Joseph disease6 and parkinsonism with ...
