Background: A novel method using diffusion-weighted imaging (DWI) allows for assessing microstructural injury in the gray matter by measuring cortical mean diffusivity (cMD). Previous studies have shown that altered cMD is related to amyloid (Aβ) cross-sectionally and can predict longitudinal cognitive decline and clinical progression, suggesting utility in clinical trials. However, the longitudinal associations between these measures are unknown.

Sweet's syndrome (or acute febrile dermatosis) is a neutrophilic dermatosis with a characteristic presentation encompassing specific clinical (fever and erythemato-violaceous oedematous papules, plaques and nodules), laboratory (neutrophilia and increased inflammatory markers), and histological (dermal neutrophilic infiltrate without vasculitis) features. Its pathophysiology is poorly understood but there seems to be an auto-inflammatory component related to mutations in inflammasome genes. It has been subdivided into its classic form, malignancy-associated, and drug-induced, according to its aetiology.

Background: Venetoclax + azacitidine is a frontline treatment for older adult acute myeloid leukemia (AML) patients and a salvage therapy for relapsed/refractory patients who have been treated with intensive chemotherapy. While this is an important treatment option, many patients fail to achieve complete remission and of those that do, majority relapse. Leukemia stem cells (LSCs) are believed to be responsible for AML relapse and can be targeted through oxidative phosphorylation reduction.

Acute liver failure (ALF) is a life-threatening condition that occurs when the liver sustains severe damage and rapidly loses its function. The primary cause of ALF is the overdose of acetaminophen (APAP), and its treatment is relatively limited. The involvement of the complement system in the development of ALF has been implicated.

Cisplatin (CIS) is a chemotherapeutic agent frequently used in cancer treatment. However, depending on the dosage and duration of use, CIS can lead to hepatotoxicity and nephrotoxicity. Iristectorin A (IRIS), a natural flavonoid, has been found to exhibit antioxidant and protective effects.
