Carbonic Anhydrase IX Enzyme in Triple Negative Breast Carcinoma: Relationship With Prognostic Factors and Response to Neoadjuvant Chemotherapy.
Eur J Breast Health

Department of General Surgery, Elazığ Fethi Sekin City Hospital, University of Health Sciences Turkey, Elazığ, Turkey.
Objective: Triple negative breast carcinoma (TNBC) is characterized by the absence of estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 receptor expression. Carbonic anhydrase IX (CA IX) is a tumor-associated cell surface glycoprotein that is involved in adaptation to hypoxia-induced acidosis and plays a role in cancer progression. The aim of this study was to investigate CA IX expression in TNBC and its relationship with treatment effect.

Article Synopsis
- Immobilized carbonic anhydrase (CA) enhances CO absorption in potassium carbonate (PC) solutions, presenting a viable alternative to traditional amine-based carbon capture methods.
- The study developed cross-scale models to assess how different enzyme immobilization materials—ranging from nanoparticle to macro-scale carriers—affect CO absorption rates, finding that nanoscale carriers are most effective.
- While increasing enzyme activity can boost absorption rates, diffusion limits, particularly in the liquid phase, impose an upper limit to this enhancement, and smaller particle sizes below 0.35 μm significantly improve performance over benchmark solutions.

Duplicated carbonic anhydrase was a member of carbonic anhydrase family. The ubiquitous carbonic anhydrase (CA) plays important roles in plants. However, the role of CA in Dunaliella parva remains to be further explored.

Purpose: To compare the efficacy of intravitreal antivascular endothelial growth factor (anti-VEGF) agents with oral carbonic anhydrase inhibitors (CAIs) in treating cystoid macular edema (CME) secondary to retinitis pigmentosa (RP).
Methods: This retrospective study analyzed 98 patients (98 eyes) with RP-CME: 47 (48.0%) received intravitreal anti-VEGF agents (Ranibizumab or Bevacizumab) and 51 (52.
