Systemic exposure following intravitreal administration of therapeutic agents: an integrated pharmacokinetic approach. 2. THR-687.

J Pharmacokinet Pharmacodyn 2021 Jul 23. Epub 2021 Jul 23.

Oxurion N.V, Gaston Geenslaan 1, 3001, leuven, Belgium.

Intravitreal (IVT) injection remains the preferred administration route of pharmacological agents intended for the treatment of back of the eye diseases such as diabetic macular edema (DME) and neovascular age-related macular degeneration (nvAMD). The procedure enables drugs to be delivered locally at high concentrations whilst limiting whole body exposure and associated risk of systemic adverse events. Nevertheless, intravitreally-delivered drugs do enter the general circulation and achieving an accurate understanding of systemic exposure is pivotal for the evaluation and development of drugs administered in the eye.

The DME demethylase regulates sporophyte gene expression, cell proliferation, differentiation, and meristem resurrection.

Proc Natl Acad Sci U S A 2021 Jul;118(29)

Department of Biological Sciences, Seoul National University, Seoul 08826, Korea;

The flowering plant life cycle consists of alternating haploid (gametophyte) and diploid (sporophyte) generations, where the sporophytic generation begins with fertilization of haploid gametes. In , genome-wide DNA demethylation is required for normal development, catalyzed by the DEMETER (DME) DNA demethylase in the gamete companion cells of male and female gametophytes. In the sporophyte, postembryonic growth and development are largely dependent on the activity of numerous stem cell niches, or meristems. Read More

Zhonghua Yan Ke Za Zhi 2021 Jul;57(7):546-551

Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Key Laboratory of Ophthalmology & Visual Sciences, Beijing 100730, China.

Cataract surgery can increase the risk of diabetic macular edema (DME) and Irvine-Gass syndrome postoperatively in nonproliferative diabetic retinopathy (NPDR) patients. An accurate distinction between DME and Irvine-Gass syndrome in NPDR patients after cataract surgery is significantly important for the selection of subsequent treatment plans and guarantee of long-term vision quality. This article elaborates the differential diagnosis and prevention of DME, in order to provide a theoretical basis for the timely prevention, accurate diagnosis and standardized treatment of DME in NPDR patients after cataract surgery.

Michael Ulbig

Dtsch Med Wochenschr 2021 Jul 13;146(13-14):874-881. Epub 2021 Jul 13.

Diabetic retinopathy has seen tremendous progress in diagnostic tools and treatment in recent 15 years. Sight threatening stages like proliferative diabetic retinopathy (PDR) and diabetic macular edema (DME) can be treated much more effectively now. The recognition of vascular endothelial growth factor (VEGF) as a driver of proliferation and macular edema has led to the development of VEGF inhibiting drugs such as antibodies (Bevacizumab), fragments of an antibody (Ranibizumab), or a so called VEGF trap (Aflibercept).

Synthesis and Characterization of Divalent Samarium and Thulium ,-Dimethylaminodiboranates.

Inorg Chem 2021 Jul 13. Epub 2021 Jul 13.

School of Chemical Sciences, University of Illinois at Urbana-Champaign, 600 S. Mathews Ave., Urbana, Illinois 61801, United States.

The syntheses and molecular structures of new Sm and Tm ,-dimethylaminodiboranate (DMADB) complexes are described. Treating SmI(THF) with Na(HBNMeBH) in THF results in the formation of Sm(HBNMeBH)(THF) (), which can be readily converted to Sm(HBNMeBH)(DME) (DME = 1,2-dimethoxyethane) or Sm(HBNMeBH)(diglyme) by exchange with the corresponding ether. We also show that Sm(HBNMeBH)(THF) can be prepared by reduction of the Sm compound Sm(HBNMeBH)(THF) with KC and that addition of 18-crown-6 to this reaction mixture results in the formation of the Sm compound Sm(HBNMeBH)(18-crown-6).

Establishing a Stable Anode-Electrolyte Interface in Mg Batteries by Electrolyte Additive.

ACS Appl Mater Interfaces 2021 Jul 6;13(28):33123-33132. Epub 2021 Jul 6.

Helmholtz Institute Ulm (HIU) Electrochemical Energy Storage, Helmholtzstraße 11, D-89081 Ulm, Germany.

Simple magnesium salts with high electrochemical and chemical stability and adequate ionic conductivity represent a new-generation electrolyte for magnesium (Mg) batteries. Similar to other Mg electrolytes, the simple-salt electrolyte also suffers from high charge-transfer resistance on the Mg surface due to the adsorbed species in the solution. In the current study, we built a model Mg cell system with the Mg[B(hfip)]/DME electrolyte and Chevrel phase MoS cathode, to demonstrate the effect of such anode-electrolyte interfacial properties on the full-cell performance.

Effects of Applied Interfacial Pressure on Li-Metal Cycling Performance and Morphology in 4 M LiFSI in DME.

ACS Appl Mater Interfaces 2021 Jul 28;13(27):31668-31679. Epub 2021 Jun 28.

Lithium-metal anodes can theoretically enable 10× higher gravimetric capacity than conventional graphite anodes. However, Li-metal anode cycling has proven difficult due to porous and dendritic morphologies, extensive parasitic solid electrolyte interphase reactions, and formation of dead Li. We systematically investigate the effects of applied interfacial pressure on Li-metal anode cycling performance and morphology in the recently developed and highly efficient 4 M lithium bis(fluorosulfonyl)imide in 1,2-dimethoxyethane electrolyte.
