The jacktree genome and population genomics provides insights for the mechanisms of the germination obstacle and the conservation of endangered ornamental plants.

Hu represents the first woody genus described by Chinese botanists, with all species classified as endangered ornamental plants endemic to China. Their characteristic spindle-shaped fruits confer high ornamental value to the plants, making them favored in gardens and parks. Nevertheless, the fruits likely pose a germination obstacle, contributing to the endangered status of this lineage.

Identification of potential molecular mechanisms and therapeutic targets for recurrent pelvic organ prolapse.

Background: The pathogenesis of recurrent pelvic organ prolapse (POP) is currently unclear. Therefore, developing targeted preventive measures is difficult. This study identified potential key pathways, crucial genes, comorbidities, and therapeutic targets associated with the occurrence and development of recurrent POP.

Comparative analysis of the complete plastid genomes in Prunus subgenus Cerasus (Rosaceae): Molecular structures and phylogenetic relationships.

Prunus subgenus Cerasus (cherry) is an economically important group that distributed in temperate regions of the northern hemisphere. However, shared interspecific morphological traits and variability across taxa of Cerasus are among the impediments to taxonomic efforts to correctly delimit taxa. This is further complicated by a lack of genetic information on these taxa, with no focused genomic or phylogenetic studies being done on Cerasus.

is an ornamental flowering cherry species, spread in Japan, Korea, Russia, and Northeast China. Little information is available regarding its genomic, with limited phylogenetic relationship study performed on until now. In this research, we reported the complete plastid genome of The complete chloroplast of this species is 158,138 bp in length, including a pair of invert repeat regions (IR) (26,463bp) that is divided by a large single-copy region (LSC) (85,959bp) and a small single-copy region (SSC) (19,253bp).

A 14-year multi-institutional collaborative study of Chinese pelvic floor surgical procedures related to pelvic organ prolapse.

Background: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.

Methods: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers.

The complete plastid genome of cherry plants (Rosaceae) and its phylogenetic implication.

is an endemic cherry species with ornamental value, spread in eastern China (Anhui, Jiangxi, Zhejiang provinces). Little information is available regarding its genomic, with limited phylogenetic relationship study performed on until now. The plastid genome was 158,024 bp in length consisting of four regions: large single-copy region (85,953 bp), small single-copy region (19,113 bp), and a pair of inverted repeat regions (26,469 bp each).

Charge Reversible and Mitochondria/Nucleus Dual Target Lipid Hybrid Nanoparticles To Enhance Antitumor Activity of Doxorubicin.

The experiment aims to increase antitumor activity while decreasing the systemic toxicity of doxorubicin (DOX). Charge reversible and mitochondria/nucleus dual target lipid hybrid nanoparticles (LNPs) was prepared. The in vitro experimental results indicated that LNPs released more amount of DOX in acidic environment and delivered more amount of DOX to the mitochondria and nucleus of tumor cells than did free DOX, which resulted in the reduction of mitochondrial membrane potential and the enhancement of cytotoxicity of LNPs on tumor cells.

Autophagy plays beneficial effect on diabetic encephalopathy in type 2 diabetes: studies in vivo and in vitro.

Objectives: The hypothalamus regulates metabolism and feeding behavior by perceiving the levels of peripheral insulin. However, little is known about the hypothalamic changes after aberrant metabolism. In this study, we investigated the changes of insulin and autophagy relevant signals of hypothalamus under diabetes mellitus.

Adenovirus-mediated downregulation of the ubiquitin ligase RNF8 sensitizes bladder cancer to radiotherapy.

The ubiquitin ligase RNF8 promotes the DNA damage response (DDR). We observed that the expression of RNF8 was increased in bladder cancer cells and that this change in RNF8 expression could be reversed by adenovirus-mediated shRNA treatment. Moreover, we found that RNF8 knockdown sensitized bladder cancer cells to radiotherapy, as demonstrated by reduced cell survival.

Dual subcellular compartment delivery of doxorubicin to overcome drug resistant and enhance antitumor activity.

In order to overcome drug resistant and enhance antitumor activity of DOX, a new pH-sensitive micelle (DOX/DQA-DOX@DSPE-hyd-PEG-AA) was prepared to simultaneously deliver DOX to nucleus and mitochondria. Drug released from DOX/DQA-DOX@DSPE-hyd-PEG-AA showed a pH-dependent manner. DOX/DQA-DOX@DSPE-hyd-PEG-AA induced the depolarization of mitochondria and apoptosis in MDA-MB-231/ADR cells and A549 cells, which resulted in the high cytotoxicity of DOX/DQA-DOX@DSPE-hyd-PEG-AA against MDA-MB-231/ADR cells and A549 cells.

Retardation of fetal dendritic development induced by gestational hyperglycemia is associated with brain insulin/IGF-I signals.

Hyperglycemia is an essential risk factor for mothers and fetuses in gestational diabetes. Clinical observation has indicated that the offspring of mothers with diabetes shows impaired somatosensory function and IQ. However, only a few studies have explored the effects of hyperglycemia on fetal brain development.

Cellular uptake and antitumor activity of DOX-hyd-PEG-FA nanoparticles.

A PEG-based, folate mediated, active tumor targeting drug delivery system using DOX-hyd-PEG-FA nanoparticles (NPs) were prepared. DOX-hyd-PEG-FA NPs showed a significantly faster DOX release in pH 5.0 medium than in pH 7.

PEG-detachable lipid-polymer hybrid nanoparticle for delivery of chemotherapy drugs to cancer cells.

The experiment aimed to increase the drug-delivery efficiency of poly-lactic-co-glycolic acid (PLGA) nanoparticles. Lipid-polymer hybrid nanoparticles (LPNs-1) were prepared using PLGA as a hydrophobic core and FA-PEG-hyd-DSPE as an amphiphilic shell. Uniform and spherical nanoparticles with an average size of 185 nm were obtained using the emulsification solvent evaporation method.

Protective effects of carbenoxolone are associated with attenuation of oxidative stress in ischemic brain injury.

Accumulating evidence has suggested that the gap junction plays an important role in the determination of cerebral ischemia, but the underlying mechanisms remain to be elucidated. In this study, we assessed the effect of a gap-junction blocker, carbenoxolone (CBX), on ischemia/reperfusion-induced brain injury and the possible mechanisms. By using the transient cerebral ischemia model induced by occlusion of the middle cerebral artery for 30 min followed by reperfusion for 24 h, we found that pre-administration of CBX (25 mg/kg, intracerebroventricular injection, 30 min before cerebral ischemic surgery) diminished the infarction size in rats.

Methylprednisolone improves the survival of new neurons following transient cerebral ischemia in rats.

Cerebral ischemia induced the proliferation and differentiation of neural stem cells in discrete regions of brain. However, only a small fraction of the neural stem/progenitor cells survives. In this report, the effects of methylprednisolone (MP) on proliferation, differentiation and survival of neural progenitor cells were explored through early MP administration after occlusion of the middle cerebral artery (MCAo).
