AI Article Synopsis
- A bioactive concept using biphasic calcium phosphate (BCP) ceramics was developed 15 years ago, focusing on a balance of stable hydroxyapatite (HA) and soluble tricalcium phosphate (TCP).
- The BCP material dissolves in the body, releasing calcium and phosphate ions that promote new bone formation, making it applicable for various biomaterial forms like bulk and injectable types.
- Extensive research and evaluation techniques demonstrate the effectiveness of BCP in bone filling, reconstruction, and ingrowth, highlighting its dynamic interactions with bone at the material interface.
Article Abstract
We have developed 15 years ago, with the collaboration of Lynch, Nery, and LeGeros in the USA, a bioactive concept based on biphasic calcium phosphate (BCP) ceramics. The concept is determined by an optimum balance of the more stable phase of HA and more soluble TCP. The material is soluble and gradually dissolves in the body, seeding new bone formation as it releases calcium and phosphate ions into the biological medium. The bioactive concept based on the dissolution/transformation processes of HA and TCP has been applied to both Bulk, Coating and Injectable Biomaterials. The events at the calcium phosphate (CaP) biomaterial/bone interface represent a dynamic process, including physico-chemical processes, crystal/proteins interactions, cells and tissue colonization, bone remodeling, finally contributing to the unique strength of such interfaces. An important literature and numerous techniques have been used for the evaluation of the fundamental physico chemical and biological performance of BCP concept. This type of artificial bone used from a long time in preclinical and in clinical trial, revealed the efficiency for bone filling, performance for bone reconstruction and efficacy for bone ingrowth at the expense of the micro macroporous BCP bioceramics.

: High-volume online hemodiafiltration (OL-HDF) has proven to be the most efficient dialysis modality and to offer better clinical outcomes in patients on hemodialysis. Longer and more frequent dialysis sessions have demonstrated clinical and survival benefits. : A single-center observational study of the first one hundred patients on nocturnal every-other-day OL-HDF was conducted with the aim of reporting the experience with this treatment schedule and evaluating analytical and clinical outcomes as well as the patient and technique survival.

The nutritional value of any food product has historically been measured by the calorific value of individual components, harking back to the days of the development of the bomb calorimeter. A fuller understanding of nutrition later took into account the need for specific components, such as proteins, carbohydrates, vitamins and minerals, that ere known to be required for good human health and growth. In milk and milk products, these include casein and whey proteins, lactose, milk fat triacylglycerides, minor lipid components (both charged and neutral), calcium, and micronutrients.

Purpose Of The Study: The preclinical study aimed to compare the healing of segmental bone defects treated with biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel with the established autologous spongioplasty. Another aim was to evaluate the hydrogel as a scaffold for osteoinductive growth factor of bone morphogenetic protein-2 (BMP-2) and stem cells.
Material And Methods: The study was conducted in an in vivo animal model.
Risk Factors Associated With the Development of Calciphylaxis in Patients With Chronic Kidney Disease: A Systematic Review.

Calciphylaxis is a rare but potentially life-threatening disease that is not yet completely understood. It occurs mainly in patients with chronic kidney disease termed calcific uremic arteriolopathy (CUA) but also affects patients with normal renal function. Although this disease's pathogenesis is unclear, it is associated with the dysregulation of calcium and phosphate and subsequent calcification of peripheral arterioles.

The radiological manifestations of calcium pyrophosphate deposition (CPPD) revolve around two main axes: the asymptomatic form and CPPD disease. The latter is a consequence of an immune response to calcium phosphate crystals. Chondrocalcinosis is broadly considered the radiographic manifestation of CPPD regardless of whether it is asymptomatic or associated with inflammatory arthritis.
