The amino acid L-methionine is an essential amino acid and is commonly used as a feed supplement in terrestrial animals. It is less suitable for marine organisms because it is readily excreted. It is also highly water soluble and this results in loss of the feed and eutrophication of the water.

- Primary myelofibrosis is a condition involving abnormal blood cell production, characterized by issues such as dysfunctional megakaryocytes and changes in bone marrow and spleen structure.
- The study focuses on the role of CD9, a protein that impacts megakaryocyte formation and interactions with the bone marrow environment, finding that its deregulation is linked to the severity of the disease.
- Results indicate that CD9 influences both the abnormal behaviors of megakaryocytes in primary myelofibrosis and their interactions with stromal cells, supporting a theory that poor cell interaction contributes to the disease's progression.
Background: Histological findings of choroidal melanomas after proton beam irradiation have been reported for complicated cases after enucleation. We present specimens of a tumor after transretinal probe excision.
Patient And Methods: One year after irradiation, the biopsy was examined histologically.
Aims: To evaluate the changes of morphological and functional characteristics of the retinal pigment epithelium (RPE)-choroid perfusion culture during cultivation.
Methods: PorcineRPE-choroid tissue was cultivated in a perfusion tissue culture system. After the indicated times, histology, immunolocalization of collagen IV and von Willebrand factor, RPE cell viability with calcein-AM, TUNEL assay and occludin immunolocalization of RPE cells were examined.
Objective: The aim was to determine systemic risk factors for acute central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) and to evaluate the usefulness of systemic diagnostics in CRAO and CRVO.
Methods: The study consisted of a retrospective chart review including 80 patients (CRAO 38, CRVO 42). All patients underwent systemic diagnostics including blood pressure measurement, blood cholesterol level, carotid Doppler imaging, transthoracic echocardiography (TTE), intraocular pressure measurement, glaucoma history and presence of thrombophilic factors.
