Reproductive capacity of spermatozoa from men with testicular failure.
Controversial reports have been published about the influence of sperm source and of the underlying testicular pathology on success rates of intracytoplasmic sperm injection (ICSI). In this controlled study, ICSI treatment cycles with testicular spermatozoa from men with obstructive and non-obstructive azoospermia were compared with ICSI ejaculated sperm cycles with semen parameters < or = 5 x ...

OBJECTIVE To determine whether platelet-activating factor (PAF) content in human spermatozoa from an isolated population is related to fertilization and pregnancy outcome. DESIGN Prospective analysis of PAF content in human spermatozoa after a Percoll gradient wash and its relation to fertilization and pregnancy outcome.

متن کاملMulti-factor failure mode critically analysis using TOPSIS
The paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (FMEA). The approach is based on the ‘technique for order preference by similarity to ideal solution’ (TOPSIS). The priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...
متن کاملWeak factor automata: the failure of failure factor oracles?
In indexing of, and pattern matching on, DNA and text sequences, it is often important to represent all factors of a sequence. One efficient, compact representation is the factor oracle (FO). At the same time, any classical deterministic finite automaton (DFA) can be transformed to a so-called failure one (FDFA), which may use failure transitions to replace multiple symbol transitions, potentia...
متن کاملThe Infantile Factor in Failure
The observations to be detailed were made at the Salomon's Welfare Centre over a period of approximately two years. All cases of failure to breast-feed were kept under observation as much as possible during this time with a view to finding out why they failed. Excluding the cases where some force outside our control deprived the child of his milk, or where the mother took matters into her own h...
