Drug-drug interaction (DDI) often causes serious adverse reactions and thus results in inestimable economic and social loss. Currently, comprehensive DDI evaluation has become a major challenge in pharmaceutical research due to the time-consuming and costly process of the experimental assessment and it is of high necessity to develop effective in silico methods to predict and evaluate DDIs accurately and efficiently. In this study, based on a large number of substrates and inhibitors related to five important CYP450 isozymes (CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A4), a series of high-performance predictive models for metabolic DDIs were constructed by two machine learning methods (random forest and XGBoost) and 4 different types of descriptors (MOE_2D, CATS, ECFP4 and MACCS).

Article Synopsis
  • PARP1 is an important target for cancer therapies, particularly for ovarian and breast cancer, but existing inhibitors often suffer from low solubility and poor permeability.
  • The study employed various virtual screening methods, including 2D similarity screening and pharmacophore screening, to assess their effectiveness on the PARP1 target.
  • Results indicated that ligand-based virtual screening methods perform best in identifying new PARP1 inhibitors with diverse structures, and incorporating them early in the screening process can enhance overall efficiency.

Background And Objectives: To provide the surgical indication for patients with myopic traction maculopathy (MTM) by investigating the postoperative outcomes after vitrectomy among different types of morphological characteristic groups.

Patients And Methods: This was a retrospective cohort study that included patients (37 eyes) diagnosed with MTM at a single institution. All 37 eyes from 37 patients with MTMs were classified into three groups: foveal retinoschisis (FS), lamellar macular hole (LMH), and foveal retinal detachment (FRD).

The arginine/glycine-rich region termed the RGG domain is usually found in G-quadruplex (G4)-binding proteins and is important in G4-protein interactions. Studies on the binding mechanism of RGG domains found that small segments (RGG motif) inside the domain contribute greatly to the G4 binding affinity. However, unlike the entire RGG domains that have been broadly explored, the role of the RGG motif remains obscure, with very limited study.

Endometriosis (EM) is one of the common and frequently encountered gynecological diseases that seriously influences women's health. Its morbidity reaches 10%-15% in women at reproductive ages, and shows an evident rising tendency. In recent years, the Chinese medicine treatment of EM has won favorable therapeutic effects with few adverse reactions.

Background: Neovascularization can cause vision loss in proliferative diabetic retinopathy (PDR) and may be affected by many factors. Stromal cell-derived factor-1 (SDF-1) is a potent stimulator of angiogenesis. The study was aimed to investigate the expression of SDF-1 and its correlation with vascular endothelial growth factor (VEGF) in the eyes with diabetic retinopathy.

Background: Neural apoptosis is generally believed to be mediated by two distinct pathways, caspase-dependant and caspase-independent pathways. This study investigated the apoptotic pathways involved in retinal ganglion cells in acute diabetes in rats.

Methods: Diabetes was induced in male Wistar rats by a peritoneal injection of streptozotocin (STZ).

Purpose: To examine the efficacy of oral doxycycline treatment (as compared to oral and topical dexamethasone) for inhibiting corneal neovascularization (CNV).

Methods: Following corneal alkali burn, rats were treated daily with oral doxycycline, oral dexamethasone, or topical dexamethasone for 14 days. Control rats were injured but were not treated.

Expression of Eag1 was detected in resected esophageal squamous cell carcinomas tissues and matched tissues by immunohistochemistry and RT-PCR. Positive expression of Eag1 protein was 75% (51/68), and mRNA was 73% (8/11) in primary cancer tissues. Eag1 protein positively stained in all 10 metastatic lymph nodes.
