Lactic acidosis in medical ICU - the role of diabetes mellitus and metformin.
To evaluate the significance of diabetes mellitus and metformin in patients admitted to medical ICU with lactic acidosis. ⋯ The presence of diabetes mellitus and metformin application is not associated with the presence of lactic acidosis in medical ICU and its mortality. The prognosis of acute renal failure of patients on metformin is good if the subjects with sepsis are excluded.

Comparative Study Clinical TrialThe influence of clonidine on oral ketamine-midazolam premedication in intellectually disabled patients indicated for dental procedures: double-blind comparison of two sedation regimes.
Dental procedures on intellectually disabled patients represent a clinical challenge. The oral administration of sedating drugs can remediate the problems with cooperation and enable the medical procedures to take place. Standard guidelines are lacking for oral sedation of the intellectually disabled. ⋯ Our study is the first to document that oral administration of ketamine and midazolam in low doses represents a safe and effective method of premedication in intellectually disabled patients indicated for dental procedures. Clonidine co-administration did not exert any substantial benefit and should be left out in this clinical setting.

The relationship between S100B protein serum levels, injury severity and Glasgow Outcome Scale values in children with CNS injuries.
The S100B protein subgroup is a thermolabile acidic calcium-binding protein, which was first described in association with the central nervous system. Destruction of nerve tissue results in S100B protein release from astrocytes and elevation of its levels in cerebrospinal fluid. If the blood-brain barrier is also damaged, S100B can pass into the systemic circulation and elevated blood levels of S100B can be detected. High S100B serum levels in patients with head injuries are predictive of possible development of secondary brain injury and may be related to the extent of permanent injury to the CNS . ⋯ Due to high variability in S100B protein serum levels in children (dependent on age and gender) no correlation between initial S100B levels and GOS was observed for our group of patients. Our results indicate that the rate of decrease of S100B protein levels back to normal values is more meaningful than its absolute value.

Effect of fluoxetine and adenosine receptor NECA agonist on G alpha q/11 protein of C6 glioma cells.
Trimeric G-proteins play a crucial role in the transmembrane signalling to intracellular pathways via effector phospholipase C (1,4,5 IP3) or adenylylcyclase (cAMP). G-protein modulation is considered to participate in the antidepressant mode of action by neurotransmitter G-protein coupled receptors (GPCR). Adenosine is naturally occured nucleoside and adenosine receptor belongs to GPCR family. Properties and functions of ubiquitous adenosine receptor were described with number of agonists and antagonists. ⋯ Main G alpha profiles are dependent on SSRI type antidepressant. Abolishing both fluoxetine evoked G alpha q/11 and and 1,4,5 IP3 signalling can indicate parallel interference between G-protein coupled receptors (GPCR) and the cell response. Presented data are first findings about adenosine receptor interaction with fluoxetine signalling. Thus in vitro studies contribute to the clarification of the molecular basis of antidepressant action.
