32-year-old male with diagnosis of central serous chorioretinopathy (CSCR) in both eyes and negative history of administration of any medicine was treated with bilateral focal laser at leakage point, with visual recovery. Recurrence occurred after 2 years in right eye and was treated successfully with acetazolamide. Second recurrence occurred after 1 year. Acetazolamide was restarted, but no improvement was noted. Thorough re-evaluation of the patient revealed a family history of tuberculosis. Ancillary investigations rendered the presumptive diagnosis of tuberculosis, and antituberculosis treatment led to visual recovery with no recurrences...

Glaucoma is a collection of optic neuropathies consisting of retinal ganglion cell death and corresponding visual field loss. Glaucoma is the leading cause of irreversible vision loss worldwide and is forecasted to precipitously increase in prevalence in the coming decades. Current treatment options aim to lower intraocular pressure (IOP) via topical or oral therapy, laser treatment to the trabecular meshwork or ciliary body, and incisional surgery. Despite increasing use of trabecular laser therapy, topical therapy remains first-line in the treatment of most forms of glaucoma...

BACKGROUND: In low level laser therapy (LLLT) low wattage lasers are used to irradiate the affected skin areas, joints, nerves, muscles and tendons without any sensation or thermal damage. Although the exact mechanism of its effect is still unknown, it seems beyond dispute that LLLT induces a variety of stimulating processes at the cellular level affecting cell repair mechanisms, the vascular system and lymphatic system. LLLT has been popular among orthopaedic practitioners for many years, whereas university medicine has remained rather sceptical about it...

Age-related macular degeneration (AMD) is the foremost cause of irreversible blindness in people over the age of 65 especially in developing countries. Therefore, an exploration of effective and alternative therapeutic interventions is an unmet medical need. It has been established that oxidative stress plays a key role in the pathogenesis of AMD, and hence, neutralizing oxidative stress is an effective therapeutic strategy for treatment of this serious disorder. Owing to autoregenerative properties, nanoceria has been widely used as a nonenzymatic antioxidant in the treatment of oxidative stress related disorders...

BACKGROUND: The treatment of erosive oral lichen planus represents a therapeutic challenge. Despite numerous existing remedies, some of these treatments display disappointed results. Since it is a chronic disease with no current cure, the best treatment should target mainly the reduction of the duration and severity of symptomatic outbreaks with minimal side effects. To date, corticosteroids remain the first choice of treatment for oral lichen planus (OLP) patients. Although, topical corticosteroids have been found to be the safest and the most successful agents in the treatment of OLP, their prolonged use may cause mucosal problems and may lead to systemic complications...

Analysis of specific DNA alterations in precision medicine of tumors is crucially important for molecular targeted treatments. Lung cancer is a prototypic example and one of the leading causes of cancer-related deaths worldwide. One major technical problem of detecting DNA alterations in tissue samples is cellular heterogeneity, that is, mixture of tumor and normal cells. Microdissection is an important tool to enrich tumor cells from heterogeneous tissue samples. However, conventional laser capture microdissection has several disadvantages like user-dependent selection of regions of interest (ROI), high costs for dissection systems and long processing times...

Nucleic-acid-based drugs are a promising class of novel therapeutics; however, their use in medicine is widely limited because of insufficient delivery into cells. This article proposes a new delivery strategy of nucleic acid fragments into cells as components of TiO2-based nanocomposites. For the first time, unmodified Dz molecules were non-covalently immobilized on TiO2 nanoparticles precovered with polylysine (TiO2•PL) with the formation of (TiO2•PL)•Dz nanocomposites. DNAzymes in the proposed nanocomposites were shown to retain their ability to cleave the RNA target in a cell-free system with the same selectivity as unbound Dz molecules...

Since traditional Chinese medicine (TCM) is a complex mixture of multiple components, the application of methodologies for evaluating single-components Western medicine in TCM studies may have certain limitations. Appropriate strategies that recognize the integrality of TCM and connect to TCM theories remain to be developed. Here we use multiple unique approaches to study the scientific connotation of a TCM formula Dan-hong injection (DHI) without undermining its prescription integrity. The blood circulation improving and healing promoting effects of DHI were assessed by a qi stagnation blood stasis rat model and a mouse model of laser irradiation induced cerebral microvascular thrombosis...
