Summary: This study evaluated a novel nano-lipoidal eye drop formulation of triamcinolone acetonide (TA) for the topical treatment of uveitis. The developed triamcinolone acetonide-loaded nanostructured lipid carriers (cTA-NLC) showed sustained release and enhanced efficacy in vitro. In vivo efficacy was tested on Wistar rats and a pharmacokinetic study was conducted in rabbits. The results demonstrated that the cTA-NLC formulation effectively managed uveitis with minimal signs of inflammation.

Summary: Triamcinolone acetonide nanocrystals (TA-NC) were obtained to improve ocular corticosteroid therapy. Self-dispersible TA-NC with a average particle size of 257 +/- 30 nm and a zeta potential of -25 +/- 3 mV were prepared by bead milling technique and spray-drying. In vivo evaluation in an ocular model showed that self-dispersible TA-NC alleviated the inflammatory response in rabbit eyes. Self-dispersible TA-NC are a promising approach for ocular disorders.

Summary: There is a clinical need for efficient eye drop formulations to treat posterior ocular segment diseases non-invasively. Cell penetrating peptides (CPPs), TAT, and penetratin are inferred as the most efficient penetration enhancers for drug delivery to the fundus oculi via topical eye drop instillation, but further high-quality experimental studies are needed for quantitative efficacy confirmation.

Summary: Patients with systemic lupus erythematosus (SLE) have an increased risk of developing posterior ocular ischaemic events (OIE), including retinal vein occlusion (RVO), retinal artery occlusion (RAO), and ischaemic optic neuropathy (ION). Comorbidities such as end-stage renal disease (ESRD), hypertension, and congestive heart failure are associated with RVO development, while hypertension and ischemic stroke increase the risk of RAO. ESRD is associated with ION, and intravenous steroid use is associated with the development of RVO.

Summary: Numerous novel nano-based ocular drug delivery systems have been developed to overcome the limitations of conventional drug delivery systems and have shown promising results in ocular disease models and clinical practice. Topical instillation of eye drops is the most common route for administering therapeutics to the eye, but efficiently treating posterior ocular diseases through this route remains a major challenge. Efforts have been dedicated to developing novel nano-based drug delivery systems that facilitate drug delivery to the retina by increasing retention time, promoting drug penetration, and targeting specific cells or tissues.

Summary: The SARS-CoV-2 pandemic has had a significant impact on eye care worldwide. While vaccination has been effective in reducing the spread and severity of COVID-19, there have been reports of complications to the posterior segment of the eye after vaccination, including retinal vascular occlusion, uveitis, and central serous chorioretinopathy. These complications are rare but require prompt diagnosis and management to prevent serious visual morbidity.

Summary: An alternative system of nanosuspensions (NS) and dissolving microneedles (MNs) was developed for the minimally invasive transscleral delivery of hydrophobic drugs. The optimized NS-loaded MNs demonstrated higher drug deposition and better penetration compared to plain drug-loaded MNs. The developed hybrid system showed excellent biocompatibility with ocular tissues and could potentially be used as an effective and minimally invasive technology for the treatment of retinal diseases.

Summary: This study discusses the use of monoclonal antibodies for targeted drug delivery in the treatment of COVID-19. It proposes the use of solid lipid nanoparticles (SLN) loaded with tocilizumab (TCZ) and cannabidiol (CBD) for oral administration. TCZ attenuates cytokine storm in SARS-CoV-2 infected patients, while CBD has anti-inflammatory properties and can modulate gene expression. The use of SLN for oral administration of TCZ-tailored CBD-loaded SLN shows potential in managing SARS-CoV-2 and related infections. Rating: 7/10

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
