Organoboron complexes have garnered significant attention due to their remarkable optical properties and diverse applications. However, synthesizing stable fused five-, six- and seven-membered organoboron complexes possess significant challenges. In this study, we successfully developed novel mono-nuclear (6-8 & 10) and di-nuclear (9) organoboron complexes supported by triaminoguanidine-salicylidene based -symmetric Schiff base ligands one-step condensation reaction with excess phenylboronic acid.

Purpose This study evaluated the efficacy of oral melatonin therapy for visual acuity and retinal and choroidal structures in patients with chronic central serous chorioretinopathy (CSCR). Methods Fourteen patients with CSCR were included; eight received oral melatonin (3 mg nightly), and six formed the control group. Best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), and choroidal vascularity index (CVI) were assessed at baseline and after one month.

Calcium (Ca) is a universal signaling cation with a prominent role as second messenger in many different plant processes, including sexual reproduction. However, there is much less knowledge about the involvement of Ca during embryogenesis processes. In this work we performed a study of Ca levels during the different stages of microspore embryogenesis in , with special attention to how Ca can influence the occurrence of different embryogenic structures with different embryogenic potential.

The purpose of this study is to evaluate the optimum frequency of oscillatory fluid flow (OFF) for increasing osteogenesis in human dental pulp cells (DPCs) in an incubating rocking shaker. DPCs from 3 donors were cultured in an osteogenic induction medium (OIM) and mechanical stimulation was applied using an incubating rocking shaker at frequencies of 0 (control), 10, 20, 30, and 40 round per minute (RPM) for 1 h/day, 5 days/week. Cell proliferation was measured using total protein quantification, and osteogenic activity was measured by alkaline phosphatase (ALP) activity, calcium deposition, and collagen production on days 7, 14, and 21 of culture.
