Abstract: A process for producing a collagen/hydroxyapatite (HA) composite scaffold comprises the steps of forming a homogenous suspension of collagen and HA in an acidic solution, lyophilizing the suspension until a desired final freezing temperature is reached to produce the composite scaffold, and optionally cross-linking the composite scaffold, wherein the ratio of HA to collagen is at least 1:10 (w/w). Also provided is a collagen/hydroxyapatite (HA) composite scaffold comprising a homogenous distribution of hydroxyapatite within a porous, crosslinked, collagen matrix, wherein the ratio of HA to collagen is at least 1:10 (w/w). Suitably, the composite scaffold has a porosity of at least 99% (v/v), and a compressive stiffness of at least 0.3 KPa. Composite scaffolds of the invention may be used to provide osteoconductive bone implants and tissue engineering implants.

Abstract: A fluid supplement is provided that is specifically tailored to meet the health and nutritional needs of a pregnant woman and her developing fetus. The fluid supplement also combats the symptoms of nausea and vomiting that are commonly associated with pregnancy. The fluid supplement contains vitamins, minerals, dietary supplements, and flavor-enhancing ingredients in amounts that safely provide health and nutritional benefits to both the woman and her developing fetus. By using the fluid supplement, a pregnant woman is able to obtain the health and nutritional benefits in a single dose of a palatable fluid supplement instead of having to swallow multiple pills per day.
