Failure to phagocytose shed outer segments, such as in the Royal College of Surgeons rat (50, 51), leads to rapid photoreceptor cell death, demonstrating the importance of clearance of spent POS by the RPE, and the essential nature of lifelong maintenance of photoreceptors for maintenance of vision.
We conclude that, when maintaining object-oriented software products, the nature of the maintenance task itself determines whether or not the presence of an inheritance hierarchy promotes maintainability.
Four contract options are to be investigated by the manufacturer depending on the coverage period and the nature of the maintenance activities to be performed.
The demanding nature of its maintenance, the vulnerability of the material, the ephemerality of the piece does relate to themes of human frailty.
Further work is required to define the precise nature of muscle maintenance by integrin-adhesomes, which is characterized by a large number of protein-protein interactions, many of which are dynamic (15).
It is therefore thought that DNA methylation may uniquely 'lock-in' the silenced state and execute a greater influence on the robust nature of Xi maintenance than other repressive regulatory mechanisms [ 9].
System performance is uncertain due to a lack of information on factors (such as siting, design, age, nature and level of maintenance, proximity to a watercourse) that affect nutrient retention rates.
The complexity and multi-step nature of tumor initiation, maintenance and metastasis has hindered the elucidation of key molecular processes defining breast cancer progression.
Instead of an open and vendor-driven platform, the closed nature forced maintenance of the product to be done by government alone — without any fully baked government technology ecosystem to support it.
These rules for rehabilitation eligibility were perceived by participants to highlight the 'reactive' nature of health care rather than a focus on "prevention" and 'maintenance of well-being'.
