Carfilzomib, lenalidomide, and dexamethasone plus transplant in newly diagnosed multiple myeloma.

In this phase 2 multicenter study, we evaluated the incorporation of autologous stem cell transplantation (ASCT) into a carfilzomib-lenalidomide-dexamethasone (KRd) regimen for patients with newly diagnosed multiple myeloma (NDMM). Transplant-eligible patients with NDMM received 4 cycles of KRd induction, ASCT, 4 cycles of KRd consolidation, and 10 cycles of KRd maintenance. The primary end point was rate of stringent complete response (sCR) after 8 cycles of KRd with a predefined threshold of ≥50% to support further study.

Impact of an Oncology Clinical Pharmacist Specialist in an Outpatient Multiple Myeloma Clinic.

Introduction: Improvements in cancer treatment and supportive care, as well as the approval of oral chemotherapy medications over the past decade, have resulted in an increasing number of cancer patients being treated in outpatient settings. Transitioning cancer treatments to the outpatient setting places greater emphasis on proper medication counseling and optimal management of adverse effects. We therefore evaluated the clinical and financial impact of an oncology clinical pharmacist specialist in an interdisciplinary multiple myeloma clinic by using a validated scoring tool.

Mitigation of Acetylcholine Esterase Activity in the 1,7-Diazacarbazole Series of Inhibitors of Checkpoint Kinase 1.

Checkpoint kinase 1 (ChK1) plays a key role in the DNA damage response, facilitating cell-cycle arrest to provide sufficient time for lesion repair. This leads to the hypothesis that inhibition of ChK1 might enhance the effectiveness of DNA-damaging therapies in the treatment of cancer. Lead compound 1 (GNE-783), the prototype of the 1,7-diazacarbazole class of ChK1 inhibitors, was found to be a highly potent inhibitor of acetylcholine esterase (AChE) and unsuitable for development.

Peripheral arterial desaturation is further exacerbated by exercise in adolescents with acute mountain sickness.

Objective: Rapid ascent to altitude can result in the development of high altitude illnesses such as acute mountain sickness (AMS). This study aimed to investigate AMS symptoms in adolescents and study basic cardiopulmonary measurements at altitude.

Methods: Thirty-eight adolescents aged 16 to 19 years flew to 3500 m from 215 m and continued over a 23-day period to ascend to a maximum altitude of 5200 m.

Route Designer: a retrosynthetic analysis tool utilizing automated retrosynthetic rule generation.

Route Designer, version 1.0, is a new retrosynthetic analysis package that generates complete synthetic routes for target molecules starting from readily available starting materials. Rules describing retrosynthetic transformations are automatically generated from reaction databases, which ensure that the rules can be easily updated to reflect the latest reaction literature.

Biomimetic synthesis of resorcylate natural products utilizing late stage aromatization: concise total syntheses of the marine antifungal agents 15G256iota and 15G256beta.

Diketo-1,3-dioxin-2-ones underwent retro-Diels-Alder reaction on heating in toluene at 110 degrees C to generate alpha,gamma,-triketo-ketenes. These were trapped with alcohols to provide 2,4,6-triketocarboxylates, which were smoothly aromatized by sequential reaction with potassium carbonate and methanolic hydrogen chloride to give resorcylate esters. The reaction was applied in the total synthesis of the marine antifungal agents 15G256beta (1), 15G256iota (2), and 15G256pi (3) and the mycotoxin S-(-)-zearalenone (4).

The closely related estrogen-regulated trefoil proteins TFF1 and TFF3 have markedly different hydrodynamic properties, overall charge, and distribution of surface charge.

The human trefoil proteins TFF1 and TFF3 are expressed predominantly in the gastrointestinal tract. They are also expressed and regulated by estrogens in malignant breast epithelial cells. TFF1 and TFF3 are small cysteine-rich acidic secreted proteins of 60 and 59 amino acids with similar isoelectric points of 4.

Molecular interactions between desmosomal cadherins.

Desmocollins (Dscs) and desmogleins (Dsgs) are cell-adhesion molecules involved in the formation of desmosome cell-cell junctions and share structural similarities to classical cadherins such as E-cadherin. In order to identify and provide quantitative information on the types of protein-protein interactions displayed by the type 2 isoforms and investigate the role of Ca(2+) in this process, we have developed an Escherichia coli expression system to generate recombinant proteins containing the first two extracellular domains, namely Dsg2(1-2) and Dsc2(1-2). Analytical ultracentrifugation, chemical cross-linking, CD, fluorescence and BIAcore have been used to provide the first direct evidence of Ca(2+) binding to desmosomal cadherins.
