Purpose: The aim of the study was to evaluate wound morphology in vivo in eyes undergoing sutureless vitrectomy.
Design: This was a prospective consecutive case series.
Methods: Twenty eyes undergoing sutureless vitrectomy were evaluated using anterior segment optical coherence tomography on days 1, 15, and 30. Ten eyes each belonged to 23-gauge (group A) and 25-gauge (group B). Scans were taken on the incision sites. Group A cases were further divided into group A1 and A2 on the basis of the surgical time of less than 15 minutes' and more than 15 minutes' duration, respectively.
Results: On day 1, the mean outer and inner incision diameters in group A were 236.6 and 146 µm, and those for group B were 118.6 and 90 µm. A significant decrease (P < 0.0001) in both the port sizes was observed in both groups' follow-up. Group B showed significant decrease (P < 0.0001) in the port sizes on l follow-up as compared with group A. Group A1 had smaller incision size as compared with group A2 on the first postoperative day, although not statistically significant(P > 0.05).
Conclusions: In both groups, the sclerotomy incisions showed good healing at 1-month duration. The 25-gauge sclerotomies showed better healing characteristics of wound morphology as compared with the 23-gauge sclerotomies.

Cultured human embryonic stem cells (hESCs) can develop genetic anomalies that increase their susceptibility to transformation. In this study, we characterized a variant hESC (vhESC) line and investigated the molecular mechanisms leading to the drift towards a transformed state. Our findings revealed that vhESCs up-regulate EMT-specific markers, accelerate wound healing, exhibit compromised lineage differentiation, and retain pluripotency gene expression in teratomas.

Introduction: Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide. Treatments for TBI patients are limited and none has been shown to provide prolonged and long-term neuroprotective or neurorestorative effects. A growing body of evidence suggests a link between TBI-induced neuro-inflammation and neurodegenerative post-traumatic disorders.

Background/aim: Organometallic complexes can decrease adhesion, migration, invasion of cancer cells, mainly through regulation of the extracellular matrix and therefore act against metastases. The aim was to investigate the anti-invasive properties of a rhenium-based metal compound, rhenium(I)-diselenoether (Re-diSe) and its effects on matrix metalloproteinase MMP-2, a key player in metastatic processes, in cultured MDA-MB231 triple-negative breast cancer cells.
Materials And Methods: Matrigel was utilized to assess cancer cell adhesion to the extracellular matrix.

Background: Gastric cancer (GC) is a highly malignant gastrointestinal tumor characterized by difficult early diagnosis and poor prognosis. Therefore, it is imperative to explore potential therapeutic targets for gastric cancer. PARP9 is abnormally expressed in a variety of tumors and is associated with tumor cell apoptosis and DNA damage.

The motility of macrophages in response to microenvironment stimuli is a hallmark of innate immunity, where macrophages play pro-inflammatory or pro-reparatory roles depending on their activation status during wound healing. Cell size and shape have been informative in defining macrophage subtypes. Studies show pro and anti-inflammatory macrophages exhibit distinct migratory behaviors, in vitro, in 3D and in vivo but this link has not been rigorously studied.
