Summary: This study investigates a new series of heterobimetallic Pt(II)-Au(I) complexes and characterizes their photophysical properties. The complexes exhibit luminescent properties in both solid state and solution. The cytotoxic activities of the complexes are compared with starting materials against different human cancer cell lines, and the heterobimetallic Pt-II-Au-I species are found to be highly cytotoxic and capable of inducing apoptosis. The complex 3 is identified as the most cytotoxic compound with the highest selectivity index, and it effectively causes cell death through cytoplasmic staining.

Summary: Inflammatory bowel diseases (IBD), such as Crohn's disease and ulcerative colitis, are global health problems with increasing frequency and unclear pathogenesis. Current treatment involves drugs like corticosteroids and derivative compounds, but more specific and effective therapies are desired. In this study, novel gold complexes were tested and found to have anti-inflammatory potential both in vitro and in vivo, particularly TGS 703, which was able to alleviate inflammation in a mouse model of colitis and showed a link to antioxidant systems. These findings suggest that gold(III) complexes may have therapeutic applications in the treatment of IBD.

Summary: Acute pancreatitis (AP) and chronic pancreatitis (CP) are severe diseases that pose a great threat to human health in high-income countries. Oxidative stress plays a significant role in the development of AP and CP, and there is growing interest in the use of antioxidant therapy to manage these conditions. Vitamin A, a well-known antioxidant, has been understudied in relation to its impact on oxidative stress in AP and CP. This review aims to evaluate the molecular targets of vitamin A and its potential role in attenuating oxidative stress in AP and CP. The findings suggest that vitamin A may influence several molecular pathways involved in antioxidative defense and cytoprotection, indicating its potential to alter the disease course of AP and CP.

Summary: Inflammatory bowel diseases (IBD) is a chronic and relapsing inflammation in the gastrointestinal tract. The incidence and prevalence of IBD are high and increasing, and current therapeutic strategies are suboptimal. This study focused on gliflozins, a group of anti-diabetic drugs, and found that they have anti-inflammatory properties. In vitro experiments showed that two gliflozins, EMPA and DAPA, suppressed nitric oxide production in macrophages, and in vivo experiments demonstrated that EMPA alleviated colitis in mice. Our findings suggest that SGLT-2 inhibitors have anti-inflammatory effects independent of their hypoglycemic effects.

Summary: Inflammatory bowel disease (IBD) patients often experience sleep and mood disorders which may be related to the disruption of the brain-gut axis. This study found that IBD patients had lower expression of BDNF mRNA but higher concentrations of proBDNF and BDNF protein compared to healthy controls. BDNF protein levels were positively correlated with sleep efficiency in the IBD group and depression severity was associated with BDNF mRNA and protein levels in the remission group.

Summary: Homotypic entosis is the process where one cancer cell invades and entirely engulfs a neighboring cancer cell within a vacuole. This study analyzed the frequency and characteristics of entotic figures in a case of breast cancer in different locations, including the primary tumor, regional lymph node, and distant metastasis. The majority of entotic figures were found in the lymph node, followed by the primary tumor and far metastasis. Notably, entosis did not result in cell death in any location, and altered morphology was observed in the far metastases. Additionally, the study proposed additional criteria for identifying pro-survival entotic structures in diagnostic histopathology.

Summary: Crohn's disease (CD) is a chronic, relapsing inflammatory bowel disease characterized by transmural inflammation in the gastrointestinal tract. Chronic fatigue is a common and often underestimated symptom in CD patients, with a higher prevalence compared to the general population. Its underlying causes and mechanisms are complex and not fully understood. Routine screening and a comprehensive, multidisciplinary approach, including psychological support, may play a crucial role in managing CD patients with chronic fatigue. Further research is needed to predict, prevent, identify, and treat fatigue associated with CD. This review aims to summarize the current knowledge on the etiology, diagnosis, and treatment of chronic fatigue in CD patients.
