Background: Recurrence of gingival pigmentation following depigmentation procedures is common, raising the question of the influence of an underlying cause, if any. Melanin, a non-hemoglobin-derived brown pigment, is the most common endogenous pigment contributing to gingival pigmentation. Hemoglobin derivatives are among the other prime pigments that contribute to gingival color. This exploratory cross-sectional study evaluated the influence of hemoglobin levels on the distribution and severity of gingival melanin pigmentation in periodontitis, gingivitis, and healthy periodontium.
Methods: Twenty subjects with periodontitis (group 1), gingivitis (group 2), and healthy periodontium (group 3) were recruited in this observational study, totaling 60 subjects. The hemoglobin levels in g/dL and Hedin Melanin Index (HMI-1977) scores were recorded for all subjects, and relevant statistical tests were applied (<0.05).
Results: A negative correlation was observed between the hemoglobin levels and the HMI scores for the whole sample and each group. This correlation was statistically significant for the whole sample and for the gingivitis group in which the correlation was moderate.
Conclusion: The inverse and significant relation between the hemoglobin levels and distribution and severity of melanin pigmentation observed for the whole sample and the gingivitis group requires further research and validation to identify and manage the confounding factors in the treatment of gingival pigmentation.

Anaemia is a common phenomenon in patients with malignant gynecological tumors. The occurrence of anaemia in the perioperative period leads to an increased probability of blood transfusion, increased surgical complications,poor wound healing, prolonged hospitalization, increased medical costs, and increased mortality. Intravenous iron, which is known for its rapid onset and lack of gastrointestinal side effects, has become increasingly prevalent in clinical practice.

However, the relationship between NO bioavailability, dynamic regulation of protein -nitrosylation by trans- and de-nitrosylases, and HFpEF pathophysiology has not been elucidated. Here, we provide novel insights into the delicate interplay between NO bioavailability and protein -nitrosylation in HFpEF.

Introduction: Diabetes is a metabolic disorder of glucose homeostasis that is a significant risk factor for neurodegenerative diseases, such as Alzheimer's disease, as well as mood disorders, which often precede neurodegenerative conditions. We examined the medial habenulainterpeduncular nucleus (MHb-IPN), as this circuit plays crucial roles in mood regulation, has been linked to the development of diabetes after smoking, and is rich in cholinergic neurons, which are affected in other brain areas in Alzheimer's disease.
Methods: This study aimed to investigate the impact of streptozotocin (STZ)-induced hyperglycemia, a type 1 diabetes model, on mitochondrial and lipid homeostasis in 4% paraformaldehyde-fixed sections from the MHb and IPN of C57BL/6 J male mice, using a recently developed automated pipeline for mitochondrial analysis in confocal images.
PLK1 inhibition impairs erythroid differentiation.

Polo-like kinase 1 (PLK1), a key regulator of the G2/M phase in mitosis, is frequently overexpressed in numerous tumors. Although PLK1 inhibitors have emerged as promising therapeutic agents for cancer, their use has been linked to significant anemia in a subset of patients, yet the underlying mechanisms remain poorly understood. In this study, we utilized an human umbilical cord blood-derived CD34 cell-based erythroid differentiation system, alongside a murine model, to investigate the impact of PLK1 inhibitors on erythropoiesis.

This study aims to assess the impact of levocarnitine supplementation on hematological and serum iron profile parameters, comparing the efficacy of oral versus intravenous (IV) administration in these patients.
Materials And Methods: This was a multicenter, randomized controlled trial was conducted on patients undergoing MHD at the hemodialysis unit of our study center in Karachi, Pakistan.
