摘要:
A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence.

Enzymatic digests of whey protein isolates were prepared using animal, bacterial and fungal proteases, and evaluated for antihypertensive activities. The antihypertension activity was obtained with a hydrolysate of whey protein isolate prepared with a porcine trypsin. The recovered hydrolysate is used to treat hypertension in mammals such as humans and domestic pets such as dogs and cats.
摘要:
Enzymatic digests of whey protein concentrates were prepared using animal, bacterial and fungal proteases, and evaluated for antihypertensive activities. The highest ACE-inhibitory activity was obtained with the purified peptide β-1g (f142–148) obtained by chemical synthesis, for which an IC50 value of 0.04 mg powder.ml−1 was found. The hydrolysates derived from BiPRO™ whey protein isolate and β-1g both gave higher antihypertensive activities (IC50 values of 0.29 to 0.90 mg powder.ml−1) than the other hydrolysates tested (IC50 values of 0.96 and 1.30 mg powder.ml−1). The recovered hydrolysate can be used to treat hypertension in mammals such as humans and domestic pets such as dogs and cats.

A regimen for calcium supplementation takes advantage of the discovery that a calcium supplement containing modified whey characterized by a calcium content of at least 3%, protein content of from 10 to 20%, and a phospholipid content of at least 2%, is of high biological value. It can be accomplished with calcium-supplemented foods that administer foods containing sufficient amounts of the modified whey to provide at least 5% of the amount of calcium required for complete nutrition on a daily basis. The regimen can benefit humans and domestic pets, in particular. More preferred levels of administration will provide at least 10% and in some cases at least 25% of the RDA for calcium for the subject.
摘要:
A holder for an annuloplasty ring having a template defining a proximal face opposite the distal face, and a peripheral edge about which the annuloplasty ring conforms. The annuloplasty ring anchors to the template using one or more flexible filaments. The template includes a single cutting well on its proximal face over which the flexible filament is suspended. Desirably, the single cutting well is located adjacent the peripheral edge so as to be away from any handle connections for ease of access. The flexible filament emerges above the proximal face of the template at only one location at the cutting well, thus presenting a one cut quick-release structure that is highly visible to the surgeon.
