Los isótopos pesados del agua recargada se mezclan progresivamente con los más livianos de aguas subterráneas más antiguas formadas en condiciones más frías y húmedas en el Pleistoceno tardío. Sin embargo, el fraccionamiento por evaporación en el trayecto final del flujo en el sudeste...

PLS is a motor neuron disease, the symptoms of which include slowly progres- sive spasticity of unknown cause without clinical signs of lower motor neuron loss. Pathological studies show degeneration of the corticospinal tracts. Subject E was female, age 58 years, with the disease for 11 years....
The combination of a unique male hormonal environment, in addition to the unique immunophenotype, points to a distinct, non-p53-dependant, pathway of tumor progres- sion in the male. Yet, despite these differences, it appears that the overall prognosis for male and female breast inva- sive ...
MUC1 is a membrane bound glycoprotein which has been demonstrated to be predictive of tumour progres- sion and worsening prognosis in both gastric [3-5] and colorectal cancer [6,7] including those related to HNPCC [8]. This increased expression has been seen more pre- dominantly at the ...
It has been reported that PTEN expression is lost in melanoma cell lines with high AKT expression, sug- gesting that the activation of AKT induced by PTEN inac- tivation or growth factor signaling activation could represent an important common pathway in the progres- sion of melanoma (probably...
Materi al and metho ds : Cyropreserved PBL of 21 HIV-1 infected subjects (median time of infection: 10 yrs, range: 6-22yrs) with different characteristics of disease progres- sion were analysed. Non-progressing patients with good viral control (LTNP, n=11) were compared to a control ...
Thus, it seems that immunization lowered amyloid load but not progres- sive neurodegeneration [168]. There have been a number of other attempts at Aβ vacci- nation [169-172]. However, it should be noted that none of these other Aβ vaccines have yet to be tested in humans, and none ...
Furthermore, Helicobacter pylori infection, the presence or absence of which was not reported in the present study, is considered to be the cause of a progres- sive accumulation of genotypic changes in gastric cancer, which may lead to sporadic gastric cancer carcinogenesis [39]. Finally, the ...
