The Covid-19 pandemic has forced many people to reconsider what medicine is all about. But debate over doctoring — and it not nothing new, 2021 marks significant anniversaries of the births two physicians who took a broad view medicine.

The effect of the level or source of dietary protein or protein-derived peptides on Ca absorption is not well understood. We determined, therefore, the influence of habitual dietary casein level, meal casein and meal casein phosphopeptide (CPP) on Ca absorption in the rat. True fractional Ca absorption was investigated in male 7-week-old rats, Wistar strain, in three separate studies using a fa...

The effects of 3 supplemental Cu concentrations on feedlot performance, mineral absorption, carcass characteristics, and ruminal S metabolism of cattle fed diets containing 60% dried distillers grains with solubles (DDGS) were evaluated in 2 experiments. Experiment 1 was conducted with 84 Angus-cross yearling steers and heifers (initial BW = 238 ± 36 kg), which were blocked by gender and alloca...

The element lithium has been discovered 200 years ago. Due to its unique properties it has emerged to play a vital role in industry, esp. for energy storage, and lithium-based products and processes support sustainable technological developments. In addition to the many uses of lithium in its inorganic forms, lithium has a rich organometallic chemistry. The development of organometallic chemist...

The dietary iron requirement for normal growth and optimum hematological values and bioavailability was determined for channel catfish Ictalurus punctatus fingerlings using eggwhite based diets supplemented with 0,5,10,20,60, and 180-mg ironkg from iron methionine or 20, 60, and 180-mg ironkg from iron sulfate. The basal diet which contained 9.2-mg ironkg, 34% crude protein and 3.1 kcal of dige...

We used water and human skin tissue to compare the surgical potential of 100-fs and 200-ps laser pulses. For investigation of threshold behavior of 100-fs and 200-ps pulses, we use water as a model for tissue. In addition to having a lower threshold, we find that energy deposition is much more consistent with 100-fs pulses. We also compared 100-fs and 200-ps laser pulse effects on the surface a...

Twenty four periparturient cows were used to determine the effects of DCAD on acid-base balance, plasma and urine mineral concentrations, health status, and subsequent lactation performance. Each group of 12 cows received either a diet containing -100 DCAD or +100 DCAD for 21 d prepartum. Both anionic and cationic groups were divided into two groups, one received a +200 DCAD and the other +400 ...

Abstract Astaxanthin (AX) is one of the commonly used feed supplements to enhance growth performance and provide antioxidant immune functions several aquatic animals. In current study, juveniles white-leg shrimp ( Litopenaeus vannamei ) with mean initial weight 0.340 ± 0.041 g were fed diets supplemented 0 (control), 25, 50, 100, 200 mg/kg for 8 weeks. At end feeding trial, shrimps exposed Vibr...
