Submacular surgery is a current alternative technique for the treatment of subfoveal choroidal neovascular membranes (CNVM). One of the difficulties often encountered with this technique is the actual removal of the neovascular membrane complex from the eye. It is often too large and fibrotic to be removed directly through a sclerotomy site without risking significant sclerotomy site complications. The vitreous cutter can be used, but despite high aspiration settings, the large, fibrotic neovascular membrane complex may still not be able to be completely removed safely and expeditiously. We describe an alternative technique using the phacofragmentation handpiece to remove large fibrotic neovascular membranes from the vitreous cavity thereby reducing sclerotomy site complications and surgical time.

c-Jun N-terminal kinases (JNKs), a subfamily of mitogen-activated protein kinases (MAPKs), are key mediators of cellular responses to environmental stress, inflammation, and apoptotic signals. The three isoforms-JNK1, JNK2, and JNK3 exhibit both overlapping and isoform-specific functions. While JNK1 and JNK2 are broadly expressed across tissues and regulate immune signaling, cell proliferation, and apoptosis, JNK3 expression is largely restricted to the brain, heart, and testis, where it plays a crucial role in neuronal function and survival.

Background: Hermansky-Pudlak syndrome (HPS) is a rare disease characterized by excessive bleeding, oculocutaneous albinism, and pulmonary fibrosis (PF). However, few studies have systematically summarized the clinical characteristics of HPS.
Objectives: To summarize the clinical characteristics, risk factors of PF, radiological and pathological presentations, and prognostic factors in patients with HPS.

Metabolic dysfunction-associated steatohepatitis (MASH) affects a large proportion of the global population and is widely regarded as the fastest growing cause of hepatocellular carcinoma. Currently, approved therapeutic strategies for MASH are limited. Therefore, this study used the Connectivity Map (CMap) database to identify a candidate compound for MASH, evaluate its efficacy in experimental models, and explore its mechanism of action.

Within most tissues, the extracellular microenvironment provides mechanical cues that guide cell fate and function. Changes in the extracellular matrix such as aberrant deposition, densification and increased crosslinking are hallmarks of late-stage fibrotic diseases that often lead to organ dysfunction. Biomaterials have been widely used to mimic the mechanical properties of the fibrotic matrix and study pathophysiologic cell function.

Introduction: Morphological and functional abnormalities of mitochondrial-associated endoplasmic reticulum (ER) membrane (MAM) have emerged as a key mediator of organelle dysfunction during liver fibrosis. Tetramethylpyrazine (TMP) was investigated as a potential therapy for liver fibrosis with an unclear mechanism.
Objectives: Considering the changes of MAM quantity and gap distance during liver fibrosis, we aimed to investigate the underlying mechanisms and their potential as therapeutic targets for TMP in inhibiting liver fibrosis.
