HISTOPATHOLOGY OF TYPE 1 DIABETES: EMERGING PARADIGMS
The immunopathology of type 1 diabetes in the pancreas is still poorly understood. Our observations provide the first direct proof for islet autoreactivity within human islets and underscore the heterogeneous and chronic disease course.

INFLUENCE OF SALIVARY CONTAMINATION ON DENTIN BOND STRENGTH OF ONE BOTTLE ADHESIVE SYSTEMS- INVITRO STUDY
For effective bonding the primer should infiltrate demineralized collagen web. The present study showed that salivary contamination has no significant effect on the Shear Bond Strength of one bottle system when it was blot dried, washed or retched with H3PO4. When the contaminated surface was dried completely there was a significant decrease in bond strength. The bond strengths to tooth structure of recent dentin bonding agents are less sensitive to common forms of contamination than assumed. Re etching without additional mechanical preparation is sufficient to provide or achieve the expected bond strength. Thus adhesive restorations should have sufficient bond strengths to prevent micro leakage around restoration margins and reinforce the tooth structure against forces that cause fracture. Reliable bonding systems have revolutionized the practice of adhesive dentistry though improvements in bonding techniques and systems have yet to be continued.

RISK FACTORS FOR CARDIAC AND RENAL DISEASE IN HYPERTENSIVE PATIENTS WITH OVERWEIGHT OR OBESITY
Along with BP and BMI, albuminuria measured in a morning urine sample asACRis a valuable low-cost index of cardiac organ damage and increased cardiovascular risk in hypertensive patients independently by MetS. On the other hand, MetS is not an independent risk factor for cardiac damage because it does not seem to add anything more than the sum of each of its components (especially SBP and adiposity indexed by BMI) to the relationship between cardiac and renal subclinical organ damage.

  CARACTERIZAÇÃO DA (CARACTERIZACIÓN DE LA) PROTEÍNA DSBC DE XYLELLA FASTIDIOSA
DsbC é expressa durante a formação do biofilme bacteriano e seu estado oligomérico responde ao ambiente redox, podendo tal modulação estar envolvida com especificidade de substrato. Este é o primeiro trabalho que descreve o papel da proteína dissulfeto isomerase na formação de biofilme microbiano.

GENES PARA PROTERODOPSINAS EN AGUAS TERMALES DE LOS ANDES COLOMBIANOS
La identificación de genes para proteorodopsinas en aguas termales amplía el rango de ecosistemas en los cuales se encuentran estos genes, que codifican para bombas de protones y pueden estar implicadas en la productividad de estas comunidades microbianas acuáticas.
