Lichen as mutualistic symbiosis is the dominant organism in various extreme terrestrial environment on Earth, however, the mechanisms of their adaptation to extreme habitats have not been fully elucidated. In this study, we chose the Antarctic dominant lichen species Usnea aurantiacoatra to generate a high-quality genome, carried out phylogenetic analysis using maximum likelihood and identify genes under positive selection. We performed functional enrichment analysis on the positively selected genes (PSGs) and found that most of the PSGs focused on transmembrane transporter activity and vacuole components.

Key bacterial microbiota in lichen thallus were discovered, which were gradually filtered and mainly derived from the crust soil, with clear host selection tendency. The study provided key information to better understand the homeostasis maintenance mechanism of the lichen symbiont and community assembly of desert lichen crust.

Methods: Clinical data of 268 POR patients (2 cases were eliminated) primarily treated with "thirteen needle acupuncture for (regulating menstruation and promoting pregnancy)" was collected from the international patient registry platform of acupuncture moxibustion (IPRPAM) from September 19, 2017 to April 30, 2023, involving 24 clinical centers including Acupuncture-Moxibustion Hospital of China Academy of Chinese Medical Sciences. LASSO and univariate Cox regression were used to screen factors influencing pregnancy outcomes, and a multivariate Cox regression model was established based on the screening results.
Aim: To assess the efficacy versus the adverse effects of various concentrations of atropine in the prevention of myopia in Asian children.
Methods: Databases (PubMed, EMBASE, the Cochrane Library and Web of science) were comprehensively searched from inception to April 2022. Types of studies included were randomized clinical trials (RCTs).
Background: Intracranial teratomas or other cystic lesions with atypical imaging manifestations can still be frequently seen clinically. The specific reasons for unusual imaging manifestations need to be further explored.
Observations: A case of adult teratoma in the posterior fossa with unusual imaging manifestations was reported.
Aim: To evaluate the difference and the correlation between the concentrations of cytokines in the aqueous humor of eyes with macular edema secondary to diabetic retinopathy (DR) or retinal vein occlusion (RVO).
Methods: This is a retrospective case control study. The aqueous humor samples were collected during intravitreal injection of anti-vascular endothelial growth factor (VEGF) for patients diagnosed with macular edema secondary to DR (DME) or RVO (RVO-ME) at Xijing Hospital from August 2021 to July 2022.

The gene mutation of isocitrate dehydrogenase-1 (IDH1) is commonly found in LGG and some GBM patients and usually carries tumor protein 53 (TP53) mutations. However, the underlying mechanisms on both mutations of glioma patients in IDH1 and TP53 are still unclear. To find the potential target markers in GBM and LGG patients with IDH1 and TP53 mutation.

Morphological and molecular phylogenetic approaches to investigate species diversity of () from Southern China were carried out in this study. Bayesian and maximum-likelihood (ML) analyses were generated based on the combined data set of internal transcribed spacer (ITS), partial regions of the nuclear ribosomal large subunit (LSU), and the largest subunit of RNA polymerase II gene sequences (RPB1).

Since atherosclerosis is a chronic inflammatory disease, we herein investigated the anti-atherosclerotic effects of CTD and the underlying mechanism. Atherosclerosis was induced in ApoE mice by feeding them with a high-fat diet (HFD) for 8 weeks, followed by administration of CTD (10, 20 mg ·kg·d, i.

This starter (Hong Qu, HQ) is made empirically by open spontaneous fermentation that is hard to control and standardize, resulting in inconsistent wine quality. This study investigates representative HQ samples from a large geographic region.

To enhance the targeted delivery of exogenous stem cells to the injury site, cell therapy combined with neural tissue engineering technology is expected to become a new strategy for treating traumatic brain injury. Collagen/heparan sulfate porous scaffolds, prepared using a freeze-drying method, have stable physical and chemical properties.

Objective: To study the protective effects of azithromycin on renal damage induced by doxorubicin and albumin in mice.
Methods: Forty male BALB/c mice were randomly divided into blank control group (Ctrl group), renal damage model group (ADR+BSA group), azithromycin treated group (Azm group) and prednisone acetate positive control group (Pdn group) in accordance with random number table method. Mice in ADR+BSA, AZM and Pdn group were injected intravenously with 9.
Betulinic acid (BA), a pentacyclic triterpenoid, has been reported to inhibit cardiovascular dysfunction under sepsis-induced oxidative stress. Nuclear factor erythroid-2 related factor-2 (Nrf2) is regarded as a key transcription factor regulating expression of endogenous antioxidative genes. To explore the preventive effects of BA against vascular hyporeactivity and the related antioxidative mechanism in sepsis, contraction and relaxation in aortas isolated from lipopolysaccharide (LPS)-challenged rats were performed.
