Design, Synthesis, Molecular Docking Study and Biological Evaluation of Novel γ-Carboline Derivatives of Latrepirdine (Dimebon) as Potent Anticancer Agents.

A series of novel γ-Carboline derivatives were designed and synthesized using the Suzuki coupling reaction to identify the leads for the activity against cancer. Interestingly, these compounds were tested for their anticancer activity against the cell lines, particularly human cancer cell lines MCF7 (breast), A549 (lung), SiHa (cervix), and Colo-205 (colon). Most of the γ-Carboline derivatives showed potent inhibitory activity in four cancer cell lines, according to in vitro anticancer activity screening.

Novice Meditators of an Easily Learnable Audible Mantram Sound Self-Induce an Increase in Vagal Tone During Short-term Practice: A Preliminary Study.

Introduction: The autonomic nervous system (ANS) plays a vital role in regulation of the physiological processes during normal and pathological conditions. Heart rate variability (HRV) is regarded as a major indicator of the self-regulatory strength and balance of parasympathetic nervous system (PNS) and sympathetic nerve system (SNS) impulses, as interpreted by the intrinsic nervous system of the heart. The present study focuses on the evaluation of the effects of audible and mindful practice of chanting meditation on HRV and on the cognitive disposition.

Reagent-based DOS: developing a diastereoselective methodology to access spirocyclic- and fused heterocyclic ring systems.

Herein, we report a diversity-oriented-synthesis (DOS) approach for the synthesis of biologically relevant molecular scaffolds. Our methodology enables the facile synthesis of fused N-heterocycles, spirooxoindolones, tetrahydroquinolines, and fused N-heterocycles. The two-step sequence starts with a chiral-bicyclic-lactam-directed enolate-addition/substitution step.

Aggressive Burkitt-like lymphoma of colon in a patient with prior celiac disease.

Background: Celiac disease (CD) and immunosuppression are the two risk factors for gastrointestinal, as well as non-gastrointestinal, non-Hodgkin's lymphomas (NHL). Recent large retrospective studies confirm that celiac disease significantly increases risk of developing small bowel lymphomas by 30 to 40 percent and other gut malignancies by 83-fold.

Case Report: A 75-year-old man with a history of CD of two-year duration presented with pallor, fatigue, and 20-pound weight loss of three weeks duration.
