The resurgence of syphilis among pregnant women in southern Chile.

Background: National rates of HIV, gonorrhoeae and syphilis have increased in Chile in recent years, but it is not known if syphilis among pregnant women (PW) is also escalating.

Aim: To explore syphilis rates among PW in a southern Chilean region and to describe clinical features of mothers and offspring.

Patients And Methods: We selected PW with positive VDRL or T.

Retrospective analysis of patients with advanced or metastatic gastric cancer in Colombia.

To assess patient and disease characteristics, treatment patterns, and associated costs in patients with advanced or metastatic gastric cancer (A/MGC) in Colombia, in both the public and private hospitals. A total of 145 patients who had received first-line chemotherapy treatment (platinum analog and/or a fluoropyrimidine) and were followed for at least 3 months after the last administration of a first-line cytotoxic agent were eligible for inclusion. Case-report forms were elaborated based on the patients' medical records from three Colombian hospitals.

[Hansen disease, an emergent condition in Chile].

Hansen's disease (HD) is caused by Mycobacterium leprae. It has a chronic course and preferentially affects the skin and the peripheral nerves. It's an emergent infection in Chile due to migration waves.

IP3 production in the hypersensitive response of lemon seedlings against Alternaria alternata involves active protein tyrosine kinases but not a G-protein.

IP3 increase and de novo synthesis of scoparone are produced in the hypersensitive response (HR) of lemon seedlings against the fungus Alternaria alternata. To elucidate whether a G-protein and/or a protein tyrosine kinase (PTK) are involved in signal transduction leading to the production of such a defensive response, we studied the HR in this plant system after treatment with G-protein activators alone and PTK inhibitors in the presence of fungal conidia. No changes in the level of IP3 were detected in response to the treatment with the G-protein activators cholera toxin or mastoparan, although the HR was observed in response to these compounds as determined by the scoparone synthesis.
