Event-related theta synchronization over sensorimotor areas differs between younger and older adults and is related to bimanual motor control.

When engaged in dynamic or continuous movements, action initiation involves modifying an ongoing motor program rather than initiating it from rest. Event-related theta synchronization over sensorimotor areas is a neurophysiological marker for modifying motor programs. We used electroencephalography (EEG) to examine how task complexity and age affect event-related synchronization (ERS) in the theta band during a dynamic bimanual, visuomotor pinch force task.

Ethnopharmacological Relevance: Ulcerative colitis (UC) is a chronic form of inflammatory bowel disease, which current treatments often show limited effectiveness. Ferroptosis, a newly recognized form of programmed cell death has been implicated in UC pathogenesis, suggesting that it may be viable therapeutic target. Tetrastigma hemsleyanum (TH) has shown potential anti-UC effects, though it is unclear whether its therapeutic benefits are mediated by ferroptosis.

Introduction: Leishmaniasis is a tropical parasitic disease caused by the protozoan Leishmania which remains a significant global health concern with diverse clinical manifestations. Transmitted through the bite of an infected sandfly, its progression depends on the interplay between the host immune response and the parasite. The disease outcome is linked to macrophage polarisation into M1 and M2 phenotypes.

Tertiary lymphoid structures (TLSs) are ectopic immune cell clusters formed in nonlymphoid tissues affected by persistent inflammation, such as in cancer and prolonged infections. They have features of the structure and function of secondary lymphoid organs, featuring central CD20+ B cells, surrounded by CD3+ T cells, CD21+ follicular dendritic cells, and CD68+ macrophages, with a complex vascular system. TLS formation is governed by lymphotoxin-α1β2, TNF, and chemokines like CCL19, CCL21, and CXCL13, differing from secondary lymphoid organ development in developing later in life at sites of chronic inflammation.

Titanium dioxide (TiO) nanoparticles (NPs) are incorporated into numerous consumer products yet data as to potential adverse health effects remains inconclusive. In this paper we physically characterize 16 nanoforms of TiO from different manufacturers of different size, crystalline structure and with surface chemistry. Physical measurements of the particles were performed and compared with those provided by manufacturers revealing several discrepancies.
