Twenty-seven accessions were collected the 5 ecological regions which experiments conducted. First experiment was an accession pur...

We read with great interest the article in CHEST (July 2002) by Masakazu et al,1 who observed a haplotype loss of class I human leukocyte antigens (HLAs) in several newly established lung cancer cell lines and identified it as a mechanism of tumor escape from the immunosurveillance system of the host. However, as for the HLA genes of lung cancer cell lines passing for many generations, such as ...

Pitanga (Eugenia uniflora L.) is an exotic fruit species of significant economic importance. However, due to genetic variability, its exploitation hampered by the lack homogeneous production. In this scenario, study aimed select pitanga genotypes according physical and physicochemical parameters fruits grown under semi-arid conditions. The was developed at Federal Rural University Semi-Arid Reg...
