Vitamin D effective ultraviolet wavelengths due to scattering in shade. Turnbull DJ, Parisi AV, Kimlin MG. J Steroid Biochem Mol Biol. 2005 Sep;96(5):431-6. Epub 2005 Jul 6. PMID: 16005208

ZaidLearn is back from another non-blogging vacation (Who cares!)! Excellent point! Anyway, before I get back to my wacky 5-part learning series (in 2 weeks time!), I need to settle something urgently, and that is to compile and organize all my University learning related OpenCourseWare (OCW) and Open Educational Resources (OER) links that are scattered here and there, into one smashing post. In short, this post is about smashing all free University learning related OCW and OER resources and collections discovered into an all-in-one (sounds like shampoo!) quick-to-access/find juicy compilation. Hopefully, it will satisfy my thirst for quick access to free University learning related content. Interestingly, this post will be a dynamic one, meaning that I will continue to update (and revamp!) it as I discover, or others share ideas and recommend new oceans of free knowledge.

Plums can be yellow, red, dark red, blue or purple. The inside flesh is succulent plums, but not some other kind of watery. The inside of the yellow or red plums. Some plums have a sweet taste, while others are tart. Many varieties of plums are scattered throughout the world, including in Japan, Europe, Santa Rosa. European Plum smaller size, while no water is Japanese plum.

Developmental toxicity evaluation of berberine in rats and mice. Jahnke GD, Price CJ, Marr MC, Myers CB, George JD. Birth Defects Res B Dev Reprod Toxicol. 2006 Jun;77(3):195-206. PMID: 16634078 DOI: 10.1002/bdrb.20075 BACKGROUND: Berberine, a plant alkaloid, is found in some herbal teas and health-related products. It is a component of goldenseal, an herbal supplement. Berberine chloride dihydrate (BCD) was evaluated for developmental toxicity in rats and mice. METHODS: Berberine chloride dihydrate was administered in the feed to timed-mated Sprague-Dawley (CD) rats (0, 3625, 7250, or 14,500 ppm; on gestational days [GD] 6-20), and Swiss Albino (CD-1) mice (0, 3500, 5250, or 7000 ppm; on GD 6-17). Ingested doses were 0, 282, 531, and 1313 mg/kg/day (rats) and 0, 569, 841, and 1155 mg/kg/day (mice). RESULTS:There were no maternal deaths. The rat maternal lowest observed adverse effect level (LOAEL), based on reduced maternal weight gain, was 7250 ppm. The rat developmental toxicity LOAEL, based on reduced fetal body weight per litter, was 14,500 ppm. In the mouse study, equivocal maternal and developmental toxicity LOAELs were 5250 ppm. Due to scattering of feed in the high dose groups, a gavage study at 1000 mg/kg/day was conducted in both species. CONCLUSIONS: In rats, maternal, but not fetal adverse effects were noted. The maternal toxicity LOAEL remained at 7250 ppm (531 mg/kg/day) based on the feed study and the developmental toxicity NOAEL was raised to 1000 mg/kg/day BCD based on the gavage study. In the mouse, 33% of the treated females died. Surviving animals had increased relative water intake, and average fetal body weight per litter decreased 5-6% with no change in live litter size. The maternal toxicity LOAEL remained at 5250 ppm (841 mg/kg/day) BCD, based on increased water consumption. The developmental toxicity LOAEL was raised to 1000 mg/kg/day BCD based on decreased fetal body weight.
