Unlabelled: The forest musk deer (FMD) farming industry is currently experiencing rapid growth, yet the dietary energy requirements for FMD remain unclear. Therefore, we explored the optimal dietary digestible energy (DE) for growing phase FMD by providing three diets with different DE levels and analyzing changes in gut microbiota. A total of 20 six-month-old FMD were used in a 62-day trial.

Quinoa, rich in pharmacologically active ingredients, possesses the potential benefit in preventing cognitive impairments induced by hypoxia. In this study, the efficacy of quinoa ethanol extracts (QEE) consumption (200 and 500 mg/kg/d, respectively) against hypobaric hypoxia (HH)-induced cognitive deficits in mice was investigated. QEE significantly ameliorated hypoxic stress induced by HH, as evidenced by improvements in baseline indices and reductions in hypoxia-inducible factor 1α levels.

Potato is the world's most important nongrain crop. Here, we report that 29 genomes from Petota and Etuberosum sections were de novo assembled, and that 248 accessions of wild potatoes, landraces and modern cultivars were re-sequenced at > 25× depth to assess genetic diversity within the Petota section. Subsequently, a graph-based pangenome was constructed by using DM8.

Background: Cutaneous hypertrophic scar is a fibro-proliferative hard-curing disease. Recent studies have proved that antagonists of angiotensin II type 1 receptor (ATR) and agonists of type 2 receptor (ATR) were able to relieve hypertrophic scar. Therefore, establishing new methods to pursue dual-target lead compounds from Chinese herbs is in much demand for treating scar.

Impact of blastocyst biopsy for preimplantation genetic testing on maternal and neonatal outcomes following single frozen embryo transfer cycles.

BMC Pregnancy Childbirth

January 2025

Assisted Reproduction Center, Northwest Women's and Children's Hospital, No. 73 Houzai Gate, Xincheng District, Xi'an, 710003, Shaanxi province, People's Republic of China.

Background: Up to now, a number of studies have explored the influence of blastocyst biopsy on maternal and neonatal outcomes, and the results have been somewhat inconsistent. Therefore, the aim of this study was to investigate whether blastocyst biopsy is associated with an elevated risk of hypertensive disorders of pregnancy (HDP) and other adverse perinatal outcomes during frozen embryo transfer (FET) cycles in singleton live births resulting from intracytoplasmic sperm injection (ICSI) in women aged ≤ 35 years.

Methods: A total of 1,008 women were involved in this study from January 2020 to June 2022, who underwent ICSI cycles and received single FET, leading to the birth of a live singleton newborn.

Florida Museum of Natural History, Dickinson Hall, 1659 Museum Road, Gainesville, FL, 32611, USA.

The Thorny Skate (Amblyraja radiata) is a vulnerable species displaying a discrete size-polymorphism in the northwest Atlantic Ocean (NWA). We conducted whole genome sequencing of samples collected across its range. Genetic diversity was similar at all sampled sites, but we discovered a ~ 31 megabase bi-allelic supergene associated with the size polymorphism, with the larger size allele having introgressed in the last ~160,000 years B.

The autonomic nervous system plays a crucial role in regulating physiological processes and maintaining homeostasis through its two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system. Dysregulation of the autonomic system, characterized by increased sympathetic activity and reduced parasympathetic tone, is a common feature in chronic kidney disease (CKD) and cardiovascular disease. This imbalance contributes to a pro-inflammatory state, exacerbating disease progression and increasing the risk for cardiovascular events.

Bone is a common site for the metastasis of malignant tumors, and Single Photon Emission Computed Tomography (SPECT) is widely used to detect these metastases. Accurate delineation of metastatic bone lesions in SPECT images is essential for developing treatment plans. However, current clinical practices rely on manual delineation by physicians, which is prone to variability and subjective interpretation.

School of Chemistry & Material Science, Northwest University, 1st Xuefu Avenue, Xi'an, Shaanxi 710127, China.

C(sp)-H bond nitration provides facile access to nitro compounds that are inaccessible through traditional nitration pathways. This work describes a C(sp)-H bond nitration of aryl alkenes using DNDMH, a nitration reagent developed previously in our lab. Notably, this novel nitration process presents excellent regioselectivity and chemoselectivity between C(sp)-H nitration and C(sp)-H nitration.

We derive a new expression for the strength of a hydrogen bond (VHB) in terms of the elongation of the covalent bond of the donor fragment participating in the hydrogen bond (ΔrHB) and the intermolecular coordinates R (separation between the heavy atoms) and θ (deviation of the hydrogen bond from linearity). The expression includes components describing the covalent D-H bond of the hydrogen bond donor via a Morse potential, the Pauli repulsion, and electrostatic interactions between the constituent fragments using a linear expansion of their dipole moment and a quadratic expansion of their polarizability tensor. We fitted the parameters of the model using ab initio electronic structure results for six hydrogen bonded dimers, namely, NH3-NH3, H2O-H2O, HF-HF, H2O-NH3, HF-H2O, and HF-NH3, and validated its performance for extended parts of their potential energy surfaces, resulting in a mean absolute error ranging from 0.
