Further observations on artificial parthenogenesis in frogs

Further Observations on Blocking Zeros in Linear Muitivariabie systems (RESEARCH NOTE).

While attempting to clarify the confusion concerning the conceptualization of "blocking zeros" in state space in the recent literature, some new observations are made on the relationship between pole-zero cancellation and transmission blocking. An important distinction between uncontrollable and unobservable eigenvalue s is pointed out; and it is argued that the description of a Blocking Zero, ...

"Further Experiments on Artificial Parthenogenesis and the Nature of the Process of Fertilization" (1900), by Jacques Loeb

Jacques Loeb [5] broadened and corrected his earlier claims concerning artificial parthenogenesis [6] in sea urchins in a series of experiments in 1900. He published these findings, ?Further Experiments on Artificial Parthenogenesis [4] and the Nature of The Process of Fertilization,? in a 1900 issue of The American Journal of Physiology. His new results amended those from earlier experiments h...

Further observations on metronidazole (Flagyl).

Unexpected cases of icterus gravidarum in infancy have in many instances been traced to drug absorption from the maternal circulation. After consulting with paediatricians, it was considered advisable to investigate under hospital supervision the effect, if any, of metronidazole ("Flagyl") on the foetus and later on the breast-fed infant. In Edinburgh a "mother and baby" survey on 96 patients c...

Further observations on subarachnoid haemorrhage.

This paper is a direct sequel to that of two of the authors (McKissock and Walsh, 1956) in which evidence was produced to suggest that surgical treatment for ruptured intracranial aneurysm led to a lower mortality rate than the 50% which had been widely accepted as the death rate under conservative treatment. In that paper was collected a series of 108 cases of ruptured aneurysm treated medical...
