Eleven patients reported significant symptoms of withdrawal upon cessation of tramadol, and five patients reported loss or reduction of libido as a side effect. Most (57/72, 79.2%) patients who reported a dose consumed experienced relief from depression at low therapeutic doses (25-150 mg/day). Fourteen patients reported taking this antidepressant for 5-10 years, and four patients reported taking tramadol for 10 or more years. Results demonstrated that most patients' comments and beliefs are consistent with the biomedical literature. Conclusions Patients' reviews coupled with a survey of the biomedical literature indicate that at low therapeutic doses in the absence of interactions with other drugs, adult patients found tramadol to be a generally safe, effective, and fast-acting medication for relief from depression.To avoid replicative senescence or telomere-induced apoptosis, cancers employ telomere maintenance mechanisms (TMMs) involving either the upregulation of telomerase or the acquisition of recombination-based alternative telomere lengthening (ALT). The choice of TMM may differentially influence cancer evolution and be exploitable in targeted therapies. Here, we examine TMMs in a panel of 17 osteosarcoma-derived cell lines, defining three separate groups according to TMM and the length of telomeres maintained. Eight were ALT-positive, including the previously uncharacterized lines, KPD and LM7. While ALT-positive lines all showed excessive telomere length, ALT-negative cell lines fell into two groups according to their telomere length HOS-MNNG, OHSN, SJSA-1, HAL, 143b, and HOS displayed subnormally short telomere length, while MG-63, MHM, and HuO-3N1 displayed long telomeres. Hence, we further subcategorized ALT-negative TMM into long-telomere (LT) and short-telomere (ST) maintenance groups. Importantly, subnormally short telomeres were significantly associated with hypers
