List of results

• WBR0655  + (This profile is commonly seen in patients with perimenopause. What differentiates it from menopause is the slight increase in estrogen levels, even compared to premenopausal women.)

• WBR0591  + (Ulcerative colitis is characterized by the presence of submucosal inflammation with friable pseudopolyps on biopsy.)
• WBR0748  + (Urinary IgG and IgM may be found in patients with membranous nephropathy. They may be utilized as biological biomarkers for follow-up and progression. Nonetheless, their role still needs to be validated.)
• WBR1142  + (Usually a referral is not a right answer in the USMLE. Referrals to an orthopedic surgeon may be indicated if the vertebral fracture causes spinal nerve entrapment .)
• WBR0778  + (Usually seen in biopsies of acanthosis nigricans.)

Vincristine binds specifically to beta-tubulin, thereby blocking the polymerization of beta-tubulin with alpha-tubulin into microtubules. Vincristine does not stabilize the microtubule but rather inhibits its assembly.rotubule but rather inhibits its assembly.)
• WBR0159  + (Vincristine is an alkaloid that binds to β … Vincristine is an alkaloid that binds to β-tubulin dimers, thereby inhibiting the assembly of microtubules and blocking microtubule formation in the mitotic spindle (M-phase arrest). Because cancer cells divide more rapidly, there is a therapeutic window which allows vincristine to be used as a chemotherapeutic agent. Mitosis occurs after cells have duplicated their genomes in S phase. Thus, cells which are stalled in mitosis will appear to have doubled DNA content, which is pictured in the flow cytometry plot above.pictured in the flow cytometry plot above.)
