Eucalyptus adult material requires more successive subcultures in the in vitro multiplication phase for increased vigor and cellular activity. This study evaluated the endophytic manifestation and shoot multiplication of one 13-year-old Eucalyptus benthamii clone under different culture conditions and used canopy branches(CB) and trunk base material as explant sources. The culture media were wood plant medium(WPM), Murashige and Skoog medium(MS) and JADS(Correia and co-authors medium).Based on the results of the initial multiplication experiment, further tests examined sucrose concentrations and p H. Morphophysiology, dry mass production, endophyticmanifestation and histochemical were determined. Explant sources responded differently to MS and JADS media, but the WPM medium promoted homogeneous *** responses were similar for both explant sources when sucrose concentrations varied. Shoots died in the absence of sucrose, showed high oxidation at 60 g L-1 and optimal development at 30 g L-1. Endophytes were more evident for shoots from the CB origin. Explant sources responded distinctively to treatment due to physiological and intrinsic genetic factors. Therefore, explant sources, different culture media, sucrose concentration and p H may determine micropropagation success and influence the presence and/or intensity of endophytic manifestation.

Physiological conditioning of seeds has been shown to increase the uniformity of seedlings;thus, it has been useful for propagating native tree species from the Brazilian Cerrado which, otherwise, are difficult to propagate successfully. The objective of this work was to evaluate the effect of physiological conditioning of Alibertia edulis seeds by soaking for 5 or 10 days in solutions of varying osmotic potential. After conditioning, seeds were dried down to original water content, sown on sheets of germitest paper inside gerbox plastic boxes, and incubated at 25°C. We evaluated the effect of conditioning by studying seed germination and vigor. Seed conditioning by osmotic pretreatment showed positive effects;however, germination and growth of seedlings from seeds conditioned at osmotic potentials of -0.3 to -0.7 MPa were reduced. Osmoconditioning for 10 days at -0.7 MPa resulted in increased percent germination, indicating that the longest imbibition period in the osmotic solution of the lowest osmotic potential (-1.3 MPa) favored the seed germination process. A. edulis seeds did not require conditioning to attain high germination rates;nonetheless, osmotic conditioning reduced average seed-germination time.

First described in Hiroshima City Hospital in 1990, Takotsubo Cardiomyopathy emerged as an important differential diagnosis for acute coronary syndrome, since this disease mimics some commemoratives presentations of acute coronary syndrome such as chest symptoms, electrocardiographic changes and cardiac injury biomarker alteration. Also, it"s important to emphasize that, although it commonly occurs among woman, TCC can happen in males, as demonstrated in other studies which 10% of the cases occurred in male sex. In this way, this study shows the importance of Takotsubo Cardiomyopathy as a differential diagnosis for acute coronary syndrome.
