- Abstract:
- ... At present there are no herbicides registered for broadleaf weed control in buckwheat. Clopyralid, mixed with desmedipham, was anticipated to provide early-season broadleaf weed suppression with minimal crop injury. However, field trials resulted in limited success which brought to question the fate and availability of clopyralid for weed control. A 4-year field study was conducted in Lithuania to ...

- Abstract:
- ... The acaricidal effects of an active constituent derived from Petroselinum sativum seeds and its derivatives were determined using impregnated fabric disk bioassay against Dermatophagoides farinae, Dermatophagoides pteronyssinus, and Tyrophagus putrescentiae and compared with that of synthetic acaricide. The acaricidal constituent of P. sativum was isolated by various chromatographic techniques and ...

- Abstract:
- ... The purpose of this study was to investigate the distinct roles of advanced glycation end products (AGEs) on insulin-mediated glucose disposal in 3T3-L1 adipocytes and C2C12 skeletal muscle cells. AGE-modified proteins, namely, GO-AGEs, were prepared by incubating bovine serum albumin (BSA) with glyoxal (GO) for 7 days. Glucose utilization rates and the expression of insulin signaling-associated p ...

In this study, Lactobacillus paracasei subsp. paracasei NTU 101 (NTU 101F) and Lactobacillus plantarum NTU 102 (NTU 102F) were used as starters to ferment soy skim milk. This was then used as a nutritional supplement for 8 weeks to ovariectomized (OVX) mice. This study reveals that soy skim milk ferm ...

A standard dairy fat (SDF) with a 70% SFA content and a naturally enriched dairy fat (EDF) in vaccenic, rumenic and α-linolenic acids and low in SFA (54%) have been examined in a 4-week repeated dose oral toxicity study as a daily dose of 2000 mg/kg bw by gavage in rats. Comparisons were established with a third group of rats ...

The opposite approach, "bottom-up" evaluation of measurement uncertainty, leads to great difficulties in evaluating all of the pesticides in a consi ...
