Parameters of Experimental Activity in the Study of the Cognitive Abilities of Rhesus Monkeys ( Macaca mulatta ) and Baboons ( Papio hamadryas )
We compared experimental activity, behavioral activity in the experiment, of rhesus monkeys (Macaca mulatta) and baboons (Papio hamadryas). Baboons showed higher levels of experimental activity. The contrast in the activity between the species is probably associated with species-specific characteristics of the behavior and different ability to adapt under new conditions. In particular, they may be the result of lower plasticity of rhesus monkeys with respect to experimental conditions.

Response of the Hemostatic System to Acute Vital Stress in Rats
We studied the effect of acute vital stress on the parameters of the hemostasis system in young and old Wistar rats. The psychotraumatic effect was simulated as a situation of emotional stress at the sight of a predator (Indian python) catching and eating a conspecific. In young rats, acute vital stress was followed by inhibition of platelet aggregation, hypercoagulation by the external pathway and final stages of plasma hemostasis, and a decrease in fibrinogen and antithrombin III levels against...

High somatostatin receptor expression and efficacy of somatostatin analogues in patients with metastatic Merkel cell carcinoma
Abstract Background Merkel cell carcinoma (MCC) is an aggressive, high‐grade, cutaneous neuroendocrine tumour (NET). PD‐1/PD‐L1 blocking agents have efficacy in metastatic MCC (mMCC), but half of patients do not derive durable benefit. Somatostatin analogues (SSA) are commonly used to treat low‐ and moderate‐grade NETs that express somatostatin receptors (SSTR). Objectives To assess SSTR expression and efficacy of SSA in mMCC, a high‐grade NET. Methods In this retrospective...

Epitope competition and neutralizing antidrug antibodies: immune monitoring of antiprogrammed death‐1 therapies and lessons learned from natalizumab
Abstract We read with interest the BJD online publication by Gambichler and colleagues1 about a decline of programmed death (PD)‐1+ circulating T regulatory cells (Tregs) predicting clinical outcome in anti‐PD‐1 therapy. The study highlights the potential and importance of immune monitoring in anti‐PD‐1 checkpoint therapy in malignant melanoma. However, their conclusion about anti‐PD‐1 antibody treatment effecting a decline of PD‐1+ Tregs is misleading.
