During routine sampling of northern pike, a male with circular blue-metallic granular spots mainly located on the head and back was identified. Histological investigations presented multifocally thickened epidermis rich in basophilic large structures with a granulated rim and a dense, non-granulated center. Other organs showed no signs of infection.

Studying the blood cell morphology of marine mammals provides an opportunity to elucidate the physiological mechanisms of adaptive changes associated with the aquatic habitat that occur at the cellular level, as well as adaptations to changing environmental conditions and under various physiological and pathological processes. The Baikal seal [ (family Phocidae)] is endemic to the freshwater Lake Baikal, but comprehensive hematology data are not available. We studied the morphological features of blood cells of twelve clinically normal, adult Baikal seals ( = 6 males, = 6 females) from two oceanariums under professional care for eight years.

Immediate allergic responses, orchestrated by basophils and mast cells, are pivotal in severe allergic reactions. The flow cytometry-based Basophil Activation Test (BAT) is a clinically important assay for testing allergic reactions using CD63 and CD203c as endpoints. The test measures the concentration dependent response to the allergens providing a functional readout of the patients' allergies.

Targeting alarmins in asthma- From the bench to the clinic.

J Allergy Clin Immunol

Over the past two decades, mechanistic studies of allergic and type 2 (T2)-mediated airway inflammation have led to multiple approved therapies for the treatment of moderate-to-severe asthma. The approval and availability of these monoclonal antibodies targeting immunoglobulin E, a type 2 cytokine (IL-5) and/or cytokine receptors (IL-5Rα, IL-4Rα) has been central to the progresses made in the management of moderate-to-severe asthma over this period. However, there are persistent gaps in clinician's ability to provide precise care given that many patients with type 2-high asthma do not respond to the IgE or T2 cytokine-targeting therapies and patients with type 2-low asthma have limited therapeutic options.

The purpose of the study was to investigate the effects of exercise training on the bone marrow immune microenvironment and on minimal residual disease of multiple myeloma patients who completed first-line induction treatment. Eight multiple myeloma patients underwent 5 months of exercise training along with standard medical treatment. Eight age- and sex-matched patients who received medical treatment only, served as controls.
