Background: T-cell densities are associated with colorectal cancer outcome, but the significance of specific Th cell subsets is incompletely understood. We aimed to investigate the role of Th1 and Th2 cells and associated cytokine profiles.
Methods: We used multiplex IHC to identify Th1 and Th2 cells on tumor samples of more than 2,000 patients with colorectal cancer (three independent cohorts).

Methemoglobinemia is an uncommon yet potentially life-threatening condition that results from the oxidation of iron from the ferrous (Fe²⁺) to the ferric (Fe³⁺) state, rendering hemoglobin unable to effectively transport oxygen. This translates into a state of functional hypoxia despite adequate arterial oxygen tension. Among the various causes of acquired methemoglobinemia, recreational inhalation of alkyl nitrites, widely known as "poppers," is a notable but underrecognized trigger.

Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system (CNS) characterized by inflammatory demyelination and progressive neurodegeneration. Although current disease-modifying therapies modulate peripheral autoimmune responses, they are insufficient to fully prevent tissue specific neuroinflammation and long-term neuronal and oligodendrocyte loss. Growing evidence implicates various regulated cell death (RCD) pathways, including apoptosis, necroptosis, pyroptosis, and ferroptosis, not only as downstream consequences of chronic inflammation, but also as active drivers of demyelination, axonal injury, and glial dysfunction in MS.

Objective: This study investigates the mechanisms behind exercise capacity in adults with type 2 diabetes mellitus (T2DM), focusing on central and peripheral components, as described by the Fick equation.
Methods: A cross-sectional study of 141 adults with T2DM was conducted, using cardiopulmonary exercise testing, near-infrared spectroscopy (NIRS) and exercise echocardiography. Participants with sufficient-quality NIRS data were stratified into tertiles based on percentage predicted VO₂peak.

In this article, a biophysically realistic model of a soft octopus arm with internal musculature is presented. The modeling is motivated by experimental observations of sensorimotor control where an arm localizes and reaches a target. Major contributions of this article are: (i) development of models to capture the mechanical properties of arm musculature, the electrical properties of the arm peripheral nervous system (PNS), and the coupling of PNS with muscular contractions; (ii) modeling the arm sensory system, including chemosensing and proprioception; and (iii) algorithms for sensorimotor control, which include a novel feedback neural motor control law for mimicking target-oriented arm reaching motions, and a novel consensus algorithm for solving sensing problems such as locating a food source from local chemical sensory information (exogenous) and arm deformation information (endogenous).
