A series of dialkyl and methyl alkyl carbonates has been synthesized and their reactivity investigated. The behavior of preferential leaving and entering groups for the newly synthesized carbonates has been accurately investigated. Both experimental and computational studies agreed that the scale of leaving groups follows the trend: PhCH2O –, MeO– ≥ EtO–, CH3(CH2)2O –, CH3(CH2)7O – > (CH3)2CHO ...

Pancreatic volume, bicarbonate and enzyme secretion were studied after sequential and after simultaneous secretin and cholecystokinin (CCK) stimulation and the results compared. No statistical difference between sequential or simultaneous stimulation was noted. A comparison of secretin alone with simultaneous secretin plus cholecystokinin stimulation showed that the combination yielded a signif...

The precision of sodium, potassium, chloride, and bicarbonate analyses carried out by the AutoAnalyzer has been studied under routine laboratory conditions. From the results it is concluded that a further increase in precision is desirable.

The study was conducted in the summer season (April-May 2007). The fluoride concentration along with physico-chemical parameters in ground water samples was determined in various villages of Kadi tehsil at Mehsana district of Gujarat state (India), since in most of the villages it is the only source of drinking water. The fluoride concentrations in these villages varied from 0.94 to 2.81 mg/L (...

Selective elimination from 1,3-dienic allylic carbonates occurs in the presence of a catalytic amount of [Ru(C(5)Me(5))(4,4'-di-Bu(t)-2,2'-bipyridine)(CH(3)CN)]PF(6) and provides efficient access to a variety of [3]dendralenes.

Buffering of "metabolic" acid in tissues other than blood correlates closely with a change in extracellular bicarbonate concentration rather than with a change in extracellular pH. Of particular importance is the evidence for an absence of relation to change in pH. Questions are raised with respect to buffering mechanism, but simplification is offered for diagnosis. A clearer focus can be given...

We introduce a pragmatic approach towards the corrected Base Excess (BE) by including the large variability of the apparent dissociation constant pK' in non-logarithmic form in Henderson-Hasselbach bicarbonate ion equilibria thereby resulting in a significant correction both in calculated bicarbonate ion concentration and BE at 37 degrees C.
