Decoding the Molecular Enigma Behind Asbestos and Fibrous Nanomaterial-induced carcinogenesis.
J Occup Health
January 2025
Department of Pathology and Biological Responses, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8550, Japan.
Objectives: Natural fibrous mineral, asbestos, has been useful in industry for many centuries. In the 1960's, epidemiology had recognized the association between asbestos exposure and mesothelioma and the IARC designated all kinds of asbestos as Group 1 in 1987. However, various scientific enigmas remained regarding the molecular mechanisms of asbestos-induced mesothelial carcinogenesis.

Department of Gastroenterology, The Affiliated People's Hospital of Ningbo University, Ningbo, China.
Rationale: Gastric antral vascular ectasia (GAVE) is a rare acquired lesion characterized by vascular dilation in the gastric antrum, frequently results in occult or overt gastrointestinal bleeding. Endoscopic intervention remains the cornerstone of therapy. Argon plasma coagulation was previously considered a first treatment option.

Many proteins form paralogous multimers-molecular complexes in which evolutionarily related proteins are arranged into specific quaternary structures. Little is known about the mechanisms by which they acquired their stoichiometry (the number of total subunits in the complex) and heterospecificity (the preference of subunits for their paralogs rather than other copies of the same protein). Here, we use ancestral protein reconstruction and biochemical experiments to study historical increases in stoichiometry and specificity during the evolution of vertebrate hemoglobin (Hb), an αβ heterotetramer that evolved from a homodimeric ancestor after a gene duplication.

Hematol Rep
January 2025
Children's Haematology and Cancer Centre, Mount Elizabeth Hospital, Singapore 228510, Singapore.
Background: Peripheral erythrophagocytosis appears to be a unique sign of acquired immune-mediated hemolytic anemia. It is said to be rare but its prevalence among patients with autoimmune hemolytic anemia has not been studied.
Methods: In this retrospective study from July 2014 to June 2024, the clinical and laboratory features, treatment and outcomes of children diagnosed with autoimmune hemolytic anemia were described.
[Effects of a Steno Diabetes Dialogue Card-Based Intervention on Self-Perceived Health, Health Literacy, and Glycemic Control in Older Adults With Type 2 Diabetes Mellitus Living in the Community].
Hu Li Za Zhi
February 2025
School of Nursing, National Taipei University of Nursing and Health Sciences, Taiwan, ROC.
Background: The process of aging is associated with the deterioration of normal body functions as well as lower health awareness due to a reduced ability to acquire and understand health-related information. The subjects of this study were older adults with diabetes mellitus living in community settings. Visual-learning-based Steno diabetes dialogue cards were used to strengthen the learning and knowledge absorption capabilities of the subjects to improve diabetes health knowledge and increase compliance with blood sugar control protocols to achieve blood sugar control goals and delay / reduce the severity of complications.
