Q: Abstract: Placement of an unheated miniaturized oxygen electrode against the palpebral conjunctiva permits noninvasive measurement of tissue oxygen tension. In this study, the relationship between conjunctival oxygen tension (PcjO2) and standard cardiorespiratory variables was examined during a sequential resuscitation protocol after acute hemorrhage. Anesthetized dogs were rapidly bled to a mean arterial pressure of 40 mm Hg and then retransfused with the shed blood in a stepwise fashion. PcjO2 fell to 2% of control values after hemorrhage and did not return to prehemorrhage values until more than 90% of the shed blood had been reinfused. PcjO2 was among the last set of cardiorespiratory variables to return to control values during resuscitation and was the last noninvasive variable to normalize. The ratio of PcjO2 to arterial oxygen tension decreased from a prehemorrhage value of 0.76 +/- 0.05 (SEM) to 0.02 +/- 0.003 after hemorrhage, and did not increase to values greater than 0.50 until resuscitation was more than 90% complete. Conjunctival oxygen monitoring may play an important role in assessing the adequacy of resuscitation after acute hemorrhage.

Q: Abstract: Calcium performs a unique role in biology, achieving biological effects through highly specific interactions with and modulation of target proteins. It has been proposed that calcium-modulated proteins possess a characteristic, evolutionarily related, binding fold, known as the EF-hand. The high-resolution X-ray structure of alpha-lactalbumin reveals a Ca2+ binding fold that resembles an EF-hand only superficially and presumably has no evolutionary relationship with it. However, there is clear homology with the corresponding loop in c-type lysozyme (the 'parent' molecule of alpha-lactalbumin). This study, at 1.7 A resolution, represents one of the most accurate analyses of a calcium binding protein yet reported.

A: Alpha-lactalbumin possesses a novel calcium binding loop.

Q: Abstract: Pulmonary venous flow was evaluated by pulsed Doppler echocardiography in 38 patients with total anomalous pulmonary venous connection. Twenty-nine of these 38 had no associated intracardiac anomaly (Group I), and 9 had complex intracardiac anatomy associated with low pulmonary blood flow (Group II). In Group I the drainage was infracardiac in nine, supracardiac in seven, intracardiac in eight and mixed in five. In both groups, in those with venous obstruction the flow in the individual pulmonary veins and ascending or descending vein was nonphasic, varying only with respiration. Flow in the absence of obstruction was phasic, varying with the cardiac cycle. Distal to a site of obstruction the flow was nonlaminar and of high velocity irrespective of the amount of pulmonary blood flow. The pulsed Doppler technique provides important physiologic information in the patient with total anomalous pulmonary venous connection before surgical intervention.
