Mpox, formerly known as monkeypox, is a zoonotic disease caused by the Mpox virus (MPXV), which has recently attracted global attention due to its potential for widespread outbreaks. Initially identified in 1958, MPXV primarily spreads to humans through contact with infected wild animals, particularly rodents. Historically confined to Africa, the virus has expanded beyond endemic regions, with notable outbreaks in Europe and North America in 2022, especially among men who have sex with men (MSM).

Objective: Endometrial polyp (EP) is a type of pathology that is quite common in clinical practice. Although its exact etiology is not fully known, there is evidence to support that it is sensitive to hormonal stimuli. We aimed to investigate the relationship between kisspeptin (KP) and EP by comparing the genetic (tissue-blood) and immunohistochemical (IHC) expression of KP in EP lesions in patients with normal endometrial findings.

Purpose: This study aimed to evaluate the relationships among blood parameters, clinical factors, and retinopathy of prematurity (ROP) in extremely premature (EP) infants.

Methods: This retrospective study included 153 EP infants who were categorized into two groups based on the presence of inflammatory diseases such as necrotizing enterocolitis, neonatal sepsis, bronchopulmonary dysplasia, severe intraventricular hemorrhage, preeclampsia, and premature rupture of membranes. Complete blood count parameters, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio, platelet-lymphocyte ratio (PLR), systemic inflammatory index, and platelet mass index were recorded during the first week and first month after birth.

Cultivated meat, an alternative to conventional meat, holds great promise in alleviating environmental and ethical concerns. Skeletal muscle stem cell isolation is a critical phase in cultivated meat production, and efficiency is a major determinant in the final differentiated muscle cell yield. The conventional enzymatic dissociation method for cell isolation presents drawbacks, including added costs and the destruction of vital extracellular matrix components.

Induced pluripotent stem cells (iPSCs) are generated through the reprogramming of somatic cells to an embryonic-like state by activating specific genes. They closely resemble embryonic stem cells (ESCs), in various aspects, including the expression of key stem cell genes, potency, and differentiation capabilities. iPSCs can be derived from various cell types such as fibroblasts, keratinocytes, and peripheral blood mononuclear cells (PBMCs).

Organoids, three-dimensional, stem cell-based structures that mimic the cellular and functional architecture of tissues, have emerged as an innovative in vitro tool. They offer highly efficient models for studying both embryonic development and disease progression processes. Colon organoids can also be generated from biopsies obtained during a colonoscopy.

Article Synopsis
  • PCR and antigen tests (AgT) are important for diagnosing SARS-CoV-2, but traditional PCR can't determine if the virus is infectious; subgenomic RNA (sgRNA) may be a better indicator.
  • A study analyzed 109 PCR positive samples, finding that 76.14% also tested positive for AgT and various sgRNAs, with significant correlations between sgRNA and AgT positivity.
  • The results showed that higher cycle threshold (Ct) values were associated with lower AgT positivity, indicating that AgT may help assess infectiousness alongside sgRNA detection.

Autologous platelet concentrates (APCs) applied alone or combined with other biomaterials are popular bioactive factors employed in regenerative medicine. The main biological rationale of using such products is to concentrate blood-derived growth factors and cells into the wound microenvironment to enhance the body's natural healing capacity. First-generation APC is represented by platelet-rich plasma (PRP).
