Kawasaki disease (kDa) has remained a medical mystery for the last five decades with a wide array of hypothesis about potential aetiological factors, that have never been confirmed. In this brief note, I revised the state-of-the-art for the so-called 'wind hypothesis', claiming that the nature and types of aerosols, particularly fine ones, can account for a central part of this research avenue and the relation to kDa. Characterizing their chemical nature, in particular of the composition in trace elements, as well as their biological components (bacteria, fungi and viruses) stands up today as the most promising avenue towards constraining the range of environmental factors modulating or being responsible for this long-debated disease. Understanding kDa thanks to its unprecedented epidemiological record in Japan, going back to before the 1970s, may also improve our understanding of other similar vasculitis and rheumatic diseases.

Purpose: It is widely acknowledged that parental input plays an important role in typical language development. Less is known about the input provided to children with (suspected) developmental language disorder (DLD) or those at risk for DLD. These children may not benefit from parental input in the same way as their typically developing peers, and different aspects of parental input may be more important for them.

Purpose: Central hypovolemia is considered to lead to a compensatory increase in cardiac contractility. From a physiological perspective, left ventricular (LV) twisting motion, which plays an important role in maintaining cardiac output, should be enhanced during central hypovolemia, but previous studies have shown inconsistent findings. Using 3D echocardiography, we tested the hypothesis that the LV twisting and untwisting motion would be enhanced during severe central hypovolemia.

Detoxifying reactive oxygen species (ROS) that accumulate under saline conditions is crucial for plant salt tolerance. The Salt Overly Sensitive (SOS) pathway functions upstream, while flavonoids act downstream, in ROS scavenging under salt stress. However, the potential crosstalk between the SOS pathway and flavonoids in regulating salt stress responses and the associated mechanisms remain largely unexplored.

Background: Breast cancer is the second most common cancer in women worldwide. Treatments for this disease often result in side effects such as pain, fatigue, loss of muscle mass, and reduced quality of life. Physical exercise has been shown to effectively mitigate these side effects and improve the quality of life in patients with breast cancer.

Endometriosis is a chronic disorder in which endometrial-like tissue presents outside the uterus. Patients with endometriosis have been shown to exhibit aberrant immune responses within the lesion microenvironment and in circulation which contribute to the development of endometriosis. Thymic stromal lymphopoietin (TSLP) is an alarmin involved in cell proliferation and the induction of T helper 2 (Th2) inflammation in various diseases, such as asthma, atopic dermatitis, and pancreatic and breast cancer.
