Chromoblastomycosis (CBM) is a chronic neglected fungal disease that causes serious damage to the physical and mental health of patients. 5-Aminolevulinic acid photodynamic therapy (ALA-PDT) has garnered significant attention in the recent era for the treatment of CBM and has exhibited promising effects in several clinical case reports. We established a mice footpad infection model with and analyzed the impact of PDT treatment on the immune response of macrophages using single-cell sequencing.

Circulating histones have been identified as essential mediators that lead to hyperinflammation, platelet aggregation, coagulation cascade activation, endothelial cell injury, multiple organ dysfunction, and death in severe patients with sepsis, multiple trauma, COVID-19, acute liver failure, and pancreatitis. Clinical evidence suggests that plasma levels of circulating histones are positively associated with disease severity and survival in patients with such critical diseases. However, safe and efficient therapeutic strategies targeting circulating histones are lacking in current clinical practice.

Basic helix-loop-helix domains in yeast regulatory proteins Ino2 and Ino4 mediate formation of a heterodimer which binds to and activates expression of phospholipid biosynthetic genes. The human proto-oncoprotein c-Myc (Myc) and its binding partner Max activate genes important for cellular proliferation and contain functional domains structure and position of which strongly resembles Ino2 and Ino4. Since Ino2-Myc and Ino4-Max may be considered as orthologs we performed functional comparisons in yeast.

Diclofenac etalhyaluronate, an active pharmaceutical ingredient in JOYCLU (JCL), serves as a joint function improvement agent in knee and hip osteoarthritis patients. However, frequent cases of anaphylaxis induced by JCL administration have been reported. Recent clinical research suggests the potential utility of the basophil activation test (BAT) in predicting JCL-induced anaphylaxis.

Stroke Research Group, Department of Clinical Neurosciences, University of Cambridge, United Kingdom. (Z.S., E.L.H., H.S.M.).
Background: Endothelial dysfunction and inflammation have been implicated in the pathophysiology of cerebral small vessel disease (SVD). However, whether they are causal, and if so which components of the pathways represent potential treatment targets, remains uncertain.
Methods: Two-sample Mendelian randomization (MR) was used to test the association between the circulating abundance of 996 proteins involved in endothelial dysfunction and inflammation and SVD.
