Abstract

To evaluate the efficacy of intravitreal bevacizumab (IVB) combined with intravitreal methotrexate (IVM) in the treatment of diabetic macular edema (DME). In this prospective, interventional contralateral eye study, patients with bilateral DME were randomly allocated to receive three monthly injections of IVB (1.25 mg/0.05 mL) plus IVM (400 μg; 0.16 cc) or IVB alone. The outcome measure was changes in the best corrected visual acuity (BCVA), central macular thickness (CMT), and central macular volume (CMV). Thirty-six treatment-naive eyes of 18 patients with a mean age of 62.38 ± 6.2 years were included in the study. BCVA logMAR changed from 0.95 ± 0.53 at baseline to 0.75 ± 0.53 in the combination group and from 0.72 ± 0.57 to 0.49 ± 0.50 in the IVB alone group at 1 month after the 3rd injection. BCVA improvement in both groups was not statistically significant compared with the baseline value (P > 0.99). Compared with the baseline values, mean CMT and CMV were reduced in both groups; however, these changes did not reach a significant level. The differences of CMT changes between the groups were not statistically significant at month 1 (P = 0.82), month 2 (P = 0.21), and month 3 (P = 0.10). Furthermore, the differences of CMV ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
