Wildlife resources are strategic resources of a country, and the investigation of which is a key task for effective management in protection and utilization. Since the 1990s, two national surveys of terrestrial wildlife resources have been carried out in China, and the situation of wildlife resources has been known to a certain extent. Due to the complexity and difficulty of national wildlife survey, we are still not able to grasp the background and dynamics of wildlife resources as a whole promptly and effectively.

Chronic low-grade inflammation(CLGI), a relatively new concept without a clear definition, refers to a nonspecific, chronic, continuous, and low-grade inflammation state, and it is closely associated with various chronic diseases, including obesity, inflammatory bowel disease, neurodegenerative diseases, and tumors. Improvement of CLGI can slow down disease progression. Anti-inflammatory treatment is an important strategy for prevention and treatment of CLGI.

Background: Patients with colorectal cancer (CRC) are prone to stress ulcer after laparoscopic surgery. The analysis of risk factors for stress ulcer (SU) in patients with CRC is important to reduce mortality and improve patient prognosis.
Aim: To identify risk factors for SU after laparoscopic surgery for CRC, and develop a nomogram model to predict the risk of SU in these patients.

Developing advanced materials with a high-entropy concept is one of the hot trends in materials science. The configurational entropy of high-entropy materials can be tuned by introducing different atomic species, which can also impart a result in excellent physical and chemical properties. In this work, we synthesized a solid-solution oxide (Cu, Mn, Fe, Cr)O by a simple and scalable solid-phase synthesis method.

Solar-selective absorbers (SSAs), as key components, play a vital role in photothermal conversion efficiency and service life. The most pressing problem with SSAs is their inconsistent optical performance, an instability constraint induced by thermal stress.

For hundreds of years, nitrogen has been well known to modulate flowering time, but the molecular genetic basis on how plants adapt to ever-changing nitrogen availability remains not fully explored. Here we explore how Arabidopsis natural variation in flowering time responds to nitrate fluctuation.

WD40 proteins play crucial roles in a broad spectrum of developmental and physiological processes. Here, we conducted a systematic characterization of this family of genes in Rosa chinensis 'Old Blush' (OB), a founder genotype for modern rose domestication.

Methods: Data derived from the China Nutrition and Health Surveillance during 2002 and 2010-2012. We calculated the mean WC and the prevalence of abdominal obesity by gender, place of residence, SES indicators (education, income, and marital status), and body mass index (BMI) categoriesand used pooled t-tests to assess the differences between the two time periods.
Context: Combination of chemotherapy and nucleic acid therapy generally take advantage of drugs anti-tumor activity together with DNA capacity to transfect cancer cells, showing great promise in cancer treatment. However, effective co-delivery of drugs and DNA in a single carrier for cancer treatment remains a challenge.
Objective: This study aimed to design a tumor targeted, pH sensitive nanocarriers for the co-delivery of gene and drug.
Objective: To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013).
Methods: The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards.
The aim of the present study was to explore the roles and possible molecular mechanism of the alleviating effect of sevoflurane pre‑treatment on the extracorporeal circulation and to investigate the possible involvement of the Toll‑like receptor (TLR3) signaling pathway. A total of 64 male Sprague Dawley rats were randomly divided into three groups: The sham operation group (H group; n=8), cardiopulmonary bypass (CPB) group (C group; n=24) and sevoflurane pre‑conditioning group (S group; n=32). The C group was subjected to tracheal intubation and mechanical ventilation, vessel puncture and catheter placement in the right femoral artery and right internal jugular vein, while no CPB was performed in the H group.

Elucidating protein translational regulation is crucial for understanding cellular function and drug development. A key molecule in protein translation is ribosome, which is a super-molecular complex extensively studied for more than a half century. The structure and dynamics of ribosome complexes were resolved recently thanks to the development of X-ray crystallography, Cryo-EM, and single molecule biophysics.
