Endodontics and diabetes: association versus causation.
Segura-Egea JJ, Cabanillas-Balsera D, Jiménez-Sánchez MC, Martín-González J. Segura-Egea JJ, et al. Int Endod J. 2019 Jun;52(6):790-802. doi: 10.1111/iej.13079. Epub 2019 Feb 14. Int Endod J. 2019. PMID: 30667519 Review.
However, the demonstration of association does not prove by itself the existence of a cause-effect relationship. Two variables can be related statistically to each other without either variable directly affecting the values of the other thus resulting in a non-causa …

Comparative hemorheology.
Baskurt OK, Meiselman HJ. Baskurt OK, et al. Clin Hemorheol Microcirc. 2013;53(1-2):61-70. doi: 10.3233/CH-2012-1576. Clin Hemorheol Microcirc. 2013. PMID: 22951622
Comparative data on blood composition and blood flow properties indicate different levels of interspecies variation for several parameters. Hematocrit and hemoglobin levels have relatively low variability among mammals, while mean cell volume and red blood cell (RBC) count …

Slow-transit Constipation.
Bharucha AE, Philips SF. Bharucha AE, et al. Curr Treat Options Gastroenterol. 2001 Aug;4(4):309-315. doi: 10.1007/s11938-001-0056-9. Curr Treat Options Gastroenterol. 2001. PMID: 11469989
The diagnosis is made after excluding colonic obstruction, metabolic disorders (hypothyroidism, hypercalcemia), drug-induced constipation, and pelvic floor dysfunction (as discussed by Wald ). ...A subtotal colectomy is effective and occasionally is indicated for patients …

Vitamins in cell culture media: Stability and stabilization strategies.
Schnellbaecher A, Binder D, Bellmaine S, Zimmer A. Schnellbaecher A, et al. Biotechnol Bioeng. 2019 Jun;116(6):1537-1555. doi: 10.1002/bit.26942. Epub 2019 Feb 21. Biotechnol Bioeng. 2019. PMID: 30793282 Free PMC article. Review.
Nowadays, chemically defined cell culture media (CCM) have replaced serum- and hydrolysate-based media that rely on complex ingredients, such as yeast extracts or peptones. Benefits include a significantly lower lot-to-lot variability, more efficient manufacturing by reduc …

Variable selection in Logistic regression model with genetic algorithm.
Zhang Z, Trevino V, Hoseini SS, Belciug S, Boopathi AM, Zhang P, Gorunescu F, Subha V, Dai S. Zhang Z, et al. Ann Transl Med. 2018 Feb;6(3):45. doi: 10.21037/atm.2018.01.15. Ann Transl Med. 2018. PMID: 29610737 Free PMC article.
In biomedical research, the purpose of variable selection is to select clinically important and statistically significant variables, while excluding unrelated or noise variables. A variety of methods exist for variable selection, but none of the …

Functional expressions of the aging brain.
Folstein M, Folstein S. Folstein M, et al. Nutr Rev. 2010 Dec;68 Suppl 2:S70-3. doi: 10.1111/j.1753-4887.2010.00351.x. Nutr Rev. 2010. PMID: 21091951 Review.
Cognitively, aging is associated with slowing of processing and memory loss. However, many studies of aging do not examine the cases to exclude demented people. The nutrition and memory in the homebound elderly study (NAME) excluded cases clinically diagnosed as hav …

Estimation of perinatal mortality in dairy calves: A review.
Cuttance E, Laven R. Cuttance E, et al. Vet J. 2019 Oct;252:105356. doi: 10.1016/j.tvjl.2019.105356. Epub 2019 Aug 16. Vet J. 2019. PMID: 31554595 Review.
In 26 studies identified by the literature search, 11 explicitly mentioned that they excluded abortion, by excluding calvings with too short a gestation length, or in a situation where calves were born in a tight cluster, excluded calvings that were more than …
