This study describes the effects of feeding growing rats with a diet containing inadequate and incomplete proteins on both the morphological and the biomechanical properties of the mandible. Female rats aged 30 d were fed freely with one of two diets, control (CD, 301 Cal/100g) and experimental (ED, 359 Cal/100g). CD was a standard laboratory diet, while ED was a synthetic diet containing cornf...

Objectives- To assess the ectopic bone formation in canine masseter muscle following the implantation of the natural bovine bone minerals (NBM) loaded with canine mesenchymal stem cells (MSCs).Design- Experimental study.Animals- four mongrel dogs.Procedures- Tripotent MSCs isolated from the canine bone marrow were loaded onto the NBM sponges and allowed to adhere. The cell-loaded scaffolds were...

Metabolic bone disorder is usually caused by abnormalities of minerals and hormones metabolism. Recently, it has been proved by several studies that the renin-angiotensin system (RAS) in local bone tissue is directly involved in bone metabolism. Activation of skeletal RAS plays an important role in bone metabolic disorders. Based on in vitro, in vivo, and clinical studies, this review explains ...

CONTEXT Pycnogenol(®) extracted from French maritime pine bark (Pinus pinaster Ait. subsp. atlantica) is functional for its antioxidant activity. OBJECTIVE To investigate the effects of Pycnogenol(®) on bone mineral density (BMD), trabecular microarchitecture and bone metabolism in ovariectomized (OVX) rats. MATERIALS AND METHODS Thirty Sprague-Dawley rats were randomized into 3 groups: SHA...

BACKGROUND Cadmium (Cd) is used in many industries. High-level exposure is associated with severe kidney and bone damage. AIM This study investigates the possible effect of occupational cadmium exposure on parathyroid gland and some minerals in workers. METHODS Environmental air monitoring of cadmium was done. Serum and urine cadmium levels, kidney function, some minerals, and plasma parath...

Chicken bone is not adequately utilized despite its high nutritional value and protein content. Although not a common raw material, chicken bone can be used in many different ways besides manufacturing of collagen products. In this study, a multi-step procedure was optimized to isolate chicken bone collagen for higher yield and quality for manufacture of collagen products. The chemical composit...

It is now well known that the skeleton serves as a store of calcium and phosphorus, and that a part of the mineral requirements of lactation is met by bone resorption. In an earlier communication (Warnock & Duckworth, 1944) the literature was surveyed and the role of the spongiosa as a source of minerals for lactation in the rat was studied under conditions of adequate calcium intake. Certain i...

Periodontal disease is an inflammatory disease with high prevalence in adults that leads to destruction of the teeth-supporting tissues. Periodontal therapy has been traditionally directed at reduction of the bacterial load to a level that encourages health-promoting bacteria and maintenance of oral-hygiene. The role of nutrition in different chronic inflammatory diseases has been the subject o...
