Introduction: Remote ischaemic conditioning (RIC) refers to the use of controlled transient ischemic and reperfusion cycles, commonly of the upper or lower limb, to mitigate cellular damage from ischaemic injury. Preclinical studies demonstrate that RIC may have a neuroprotective effect and therefore could represent a novel therapeutic option in the management of neurological disorders. The aim of this review is to comprehensively describe the current clinical evidence of RIC in neurological disorders.

Intraocular pressure (IOP) elevation is the primary risk factor and currently the main treatable factor for progression of glaucomatous optic neuropathy. In addition to direct clinical and living animal in vivo studies, ex vivo perfusion of anterior segments and whole eyes is a key technique for studying conventional outflow function as it is responsible for IOP regulation. We present well-tested experimental details, protocols, considerations, advantages, and limitations of several ex vivo model systems for studying IOP regulation.

Article Synopsis
  • Ocular hypertension, a key risk factor for glaucoma, is linked to increased activity and stiffness in the trabecular meshwork (TM) due to cellular interactions.
  • Previous research identified high levels of septin-9 in TM cells under hypertensive conditions, prompting studies on its overexpression, deficiency, and drug targeting effects.
  • Findings indicate that septin-9 impacts intraocular pressure (IOP) regulation, suggesting that modulating septin cytoskeletal organization could be a potential new treatment strategy for glaucoma.

Dorzolamide (DZD), a Carbonic anhydrase (CA) inhibitor clinically used to lower intraocular pressure, exhibits anti-inflammatory effects owing to the drug's ability to inhibit the TIR domain-containing adaptor protein (TIRAP)-mediated signalling in macrophages. Here, we investigated whether DZD intermediates also demonstrate any anti-inflammatory property like DZD but with a reduced inhibition of CA. We found that several intermediates of DZD show increased binding to TIRAP at the common interface of kinases, such as Protein kinase C-delta (PKCδ) and Bruton's tyrosine kinase (BTK).

Carbenes in general and isolable NHCs (N-heterocyclic carbenes) in particular have been useful ligands in recent years. The emergence of CAACs [cyclic(alkyl)(amino)carbenes], BICAACs [bicyclic(alkyl)(amino)carbenes], and many other carbenes has marked revolutionary milestones in this field. These carbenes possess an intriguing blend of highly electrophilic and nucleophilic characteristics, owing to their remarkably narrow HOMO-LUMO energy gap.

Article Synopsis
  • The study investigates the effectiveness of intracardiac echocardiography (ICE) in improving catheter ablation outcomes for ventricular tachycardia (VT) in adults with repaired tetralogy of Fallot (TOF).
  • Results showed that ICE significantly enhanced isthmus localization and ablation success rates, but did not improve long-term freedom from VT or affect overall procedural times and complications.
  • The conclusion emphasizes that while ICE is beneficial for tailored ablation based on individual anatomy, it does not lead to better long-term patient outcomes for VT in the context of repaired TOF.

Designing low cost, highly active and efficient non-noble metal bifunctional electrocatalysts with remarkable operational reliability for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is indispensable for large-scale water electrolysis and the development of clean energy conversion technologies. Herein, we decorated a two-dimensional (2D) selenium-blended zirconium dioxide (Se-ZrO) on the surface of a nitrogen-doped carbon heterostructure (Se-ZrO@NC), which was derived from Zr-metal-organic frameworks (Zr-MOFs), and loaded it on a stainless-steel mesh electrode. Accordingly, phenomenal electrocatalytic performance was observed for the Se-ZrO@NC-loaded electrode with a minimum overpotential of 48 mV for the HER and 251 mV for the OER at 10 mA cm current density in acidic and alkaline mediums, respectively.
