How to Fortify Beverages with Calcium by Dr
Ingredients How to Fortify Beverages With Calcium by Dr. Gerhard Gerstner Along with current developments of the overall functional foods market, the use of minerals and especially calcium salts is expected to exhibit strong growth rates. In contrary to other functional ingredients, calcium is widely known as being beneficial for human health and there is no need to explain its nutritional ad- vantages to the customer. According to Leatherhead International, future trends include growing consumer concern regarding osteoporosis and bone health, leading to increased sales of calcium salts.

Factors Affecting Precipitation of Calcium Lactate from Fermentation Broths and from Aqueous Solution

Lactic acid can be produced either by fermentation or by chemical synthesis but the biotechnological fermentation process has several advantages compared to the other one. However fermentation broth contains a number of impurities which must be removed from the broth in order to achieve more pure lactic acid. Efficiency of recovery is crucial to the economy of the whole process as well since the costs of separation and recovery are responsible for more than half of the entire cost of production. In the traditional procedure, the heated and filtered fermentation broth is concentrated to allow crystallization or precipitation of calcium lactate, followed by addition of sulphuric acid to remove the calcium in form of calcium sulphate. The disadvantage of this procedure is the relatively high solubility of calcium lactate which causes product loss in the crystallization step. Therefore we investigated the effects of four operating parameters of the crystallization/precipitation process from two different fermentation broths and from an aqueous solution. -

Protective Effects of Zinc-L-Carnosine /Vitamin E on Aspirin- Induced Gastroduodenal Injury in Dogs
PROTECTIVE EFFECTS OF ZINC-L-CARNOSINE /VITAMIN E ON ASPIRIN- INDUCED GASTRODUODENAL INJURY IN DOGS MASTER’S THESIS Presented in Partial Fulfillment of the Requirements for the Master of Science Degree in the Graduate School of the Ohio State University By Mieke Baan, DVM, MVR ***** The Ohio State University 2009 Master’s Examination Committee: Professor Robert G. Sherding, Adviser Professor Stephen P. DiBartola Associate Professore Susan E. Johnson Approved by Adviser Veterinary Clinical Sciences Graduate Program ! Copyright by Mieke Baan 2009 ABSTRACT Zinc plays a role in many biochemical functions, including DNA, RNA, and protein synthesis. The dipeptide carnosine forms a stable complex with zinc, which has a protective effect against gastric epithelial injury in-vitro and in-vivo. This randomized double-blinded placebo-controlled study investigated the protective effects of zinc-L-carnosine in combination with alpha-tocopheryl acetate (vitamin E) on the development of aspirin-induced gastrointestinal (GI) lesions in dogs. Eighteen mixed-breed dogs (mean 20.6 kg) were negative for parasites, and had normal blood work evaluations, and gastroduodenoscopic exams. On days 0 – 35, dogs were treated with 1 tablet (n=6) or 2 tablets (n=6) of 30 mg zinc-L-carnosine/ 30 IU vitamin E q12h PO, or a placebo (n=6). On days 7 – 35, all dogs were given 25 mg/kg buffered aspirin q8h PO. Endoscopy was performed on Days -1, 14, 21, and 35, and GI lesions (hemorrhages, erosions, or ulcers) were scored using a 12-point grading scale. Repeated measures ANOVA was used for statistical evaluation. The significance level was set at p ! 0.05. -
Preferred Drug List 4-Tier
Preferred Drug List 4-Tier 21NVHPN13628 Four-Tier Base Drug Benefit Guide Introduction As a member of a health plan that includes outpatient prescription drug coverage, you have access to a wide range of effective and affordable medications. The health plan utilizes a Preferred Drug List (PDL) (also known as a drug formulary) as a tool to guide providers to prescribe clinically sound yet cost-effective drugs. This list was established to give you access to the prescription drugs you need at a reasonable cost. Your out- of-pocket prescription cost is lower when you use preferred medications. Please refer to your Prescription Drug Benefit Rider or Evidence of Coverage for specific pharmacy benefit information. The PDL is a list of FDA-approved generic and brand name medications recommended for use by your health plan. The list is developed and maintained by a Pharmacy and Therapeutics (P&T) Committee comprised of actively practicing primary care and specialty physicians, pharmacists and other healthcare professionals. Patient needs, scientific data, drug effectiveness, availability of drug alternatives currently on the PDL and cost are all considerations in selecting "preferred" medications. Due to the number of drugs on the market and the continuous introduction of new drugs, the PDL is a dynamic and routinely updated document screened regularly to ensure that it remains a clinically sound tool for our providers. Reading the Drug Benefit Guide Benefits for Covered Drugs obtained at a Designated Plan Pharmacy are payable according to the applicable benefit tiers described below, subject to your obtaining any required Prior Authorization or meeting any applicable Step Therapy requirement. -
