This study aimed to investigate the effects of dietary whole-plant mulberry (WM) on testicular development and antioxidant performance in sheep.Fifty-four Hu sheep aged three months were divided into three groups and fed diets containing different proportions of WM (WM0, without WM; WM4, 4% WM; WM8, 8% WM). After a 70-day feeding trial, 15 individuals from each group were humanly slaughtered.

Neuromuscular Blocking Agents and Tracheal Intubation: Systematic Review and Meta-Analysis of Effects on Laryngeal Complications and Intubating Conditions.

Background And Aims: The use of neuromuscular blocking agents (NMBAs) in tracheal intubation is widely accepted in anesthetic induction, but adverse effects are possible. We performed a systematic review and meta-analysis to compare influence of use and nonuse of NMBAs on incidence of laryngeal complications and intubating conditions in surgical patients.

Methods: We searched PubMed, Web of Science, Embase, and Cochrane Library for randomized controlled trials comparing use of NMBAs with either placebo or no treatment for oral tracheal intubation in adult patients under general anesthesia.

Identification of key genes related to unilateral cryptorchidism in sheep by comprehensive transcriptomics and proteomics analyses.

Background: Cryptorchidism is one of the most common reproductive abnormalities in rams, which seriously harms the reproductive capacity of rams and causes significant economic losses to the sheep industry. However, there are few studies elucidating its hereditary predisposition in sheep.

Results: In the present study, the transcriptome and proteome of the cryptic (CT) and contralateral (CLT) testis from four unilaterally cryptorchid rams, and the normal testis (NT) from four healthy rams were analyzed using RNA-seq and TMT-based proteomics, respectively.

Alcoholic liver disease (ALD) is a disease with high incidence, limited therapies, and poor prognosis. The present study aims to investigate the effect of riboflavin on ALD and explore its potential therapeutic mechanisms. C57BL/6 mice were divided into the control, alcohol, and alcohol+ riboflavin groups.

Overexpression of ZlMYB1 and ZlMYB2 increases flavonoid contents and antioxidant capacity and enhances the inhibition of α-glucosidase and tyrosinase activity in rice seeds.

Anthocyanins are natural flavonoids with a high antioxidant power and many associated health benefits, but most rice produce little amounts of these compounds. In this study, 141 MYB transcription factors in 15 chromosomes, including the nucleus-localised ZlMYB1 (Zla03G003370) and ZlMYB2 (Zla15G015220), were discovered in Zizania latifolia. Overexpression of ZlMYB1 or ZlMYB2 in rice seeds induced black pericarps, and flavonoid content, antioxidant capacity, and α-glucosidase and tyrosinase inhibition effects significantly increased compared to those in the control seeds.

Oxylipin profiling analyses reveal that ω-3 PUFA is more susceptible to lipid oxidation in sheep testis under oxidative stress.

Reactive oxygen species causes oxidative stress, which oxidizes polyunsaturated fatty acids (PUFAs) to form oxidative metabolites. Sertoli cell is an important cellular metabolism of PUFA in testicular cells, and it regulates the testis development and spermatogenesis. However, the oxylipins generated in testes with different developmental statuses are lacking.

The m7G Methyltransferase Mettl1 Drives Cardiac Hypertrophy by Regulating SRSF9-Mediated Splicing of NFATc4.

Cardiac hypertrophy is a key factor driving heart failure (HF), yet its pathogenesis remains incompletely elucidated. Mettl1-catalyzed RNA N7-methylguanosine (m7G) modification has been implicated in ischemic cardiac injury and fibrosis. This study aims to elucidate the role of Mettl1 and the mechanism underlying non-ischemic cardiac hypertrophy and HF.

The positive feedback loop of the NAT10/Mybbp1a/p53 axis promotes cardiomyocyte ferroptosis to exacerbate cardiac I/R injury.

Ferroptosis is a nonapoptotic form of regulated cell death that has been reported to play a central role in cardiac ischemia‒reperfusion (I/R) injury. N-acetyltransferase 10 (NAT10) contributes to cardiomyocyte apoptosis by functioning as an RNA ac4c acetyltransferase, but its role in cardiomyocyte ferroptosis during I/R injury has not been determined. This study aimed to elucidate the role of NAT10 in cardiac ferroptosis as well as the underlying mechanism.

Extreme precipitation accelerates nitrate leaching in the intensive agricultural region with thick unsaturated zones.

Nitrate accumulation in the soil profile in the intensive agricultural region has been widely concerned in the world. However, the changes in nitrate accumulation characteristics caused by climate change, such as extremely high precipitation, are not well quantified, particularly for the regions with thick unsaturated zones. Here, we resampled the soil profiles taken in normal year (2020) after extreme precipitation year (2021) (>800 cm) in three regions in the southern Loess Plateau (LP) with three different water managements including rainfed orchards (n = 10), well-irrigated orchards (n = 4) and canal-irrigated orchards (n = 8).

Objective: This study aimed to investigate the effect of Codonopsis pilosula polysaccharide (CPP) on the motility, mitochondrial integrity, acrosome integrity rate, and antioxidant ability of sheep sperm after preservation at 4°C.

Methods: Semen from healthy adult rams were collected and divided into four groups with separate addition of 0, 200, 400, and 1,000 mg/L CPP. Sperm motility was analyzed using the Computer-Assisted Semen Analysis software after preservation at 4°C for 24, 72, 120, and 168 h.

Transcriptomic analysis of the HPG axis-related tissues reveals potential candidate genes and regulatory pathways associated with testicular size in Hu sheep.

Testicular size is an excellent proxy for selecting high-fertility rams. The hypothalamus-pituitary-gonadal (HPG) axis plays an important role in regulating reproductive capacity in vertebrates, while key genes and regulatory pathways within the HPG axis associated with testicular size remain largely unknown in sheep. This study comprehensively compared the transcriptomic profiles in the hypothalamus, pituitary and testis of rams after sexual maturity between the large-testis group (LTG, testicular weight = 454.

Molecular characterization of SPATA6 and association of its SNPs with testicular size in sheep.

The testis is an important organ for maintaining fertility in males, and testis size is positively correlated with ejaculate volume, sperm motility, thus fertility. Spermatogenesis-associated 6 (SPATA6) is an evolutionarily conserved testis-specific gene reported in many species. However, the effect of SPATA6 expression levels on testicular development and the effect of single nucleotide polymorphisms (SNPs) on testis and epididymis phenotype in sheep have not been studied.

Localization and expression of phospholipase A and polyunsaturated fatty acid profile in the testis tissues of Hu sheep.

The fatty acid content and the localization and expression of phospholipase A (PLA) in the testis of Hu sheep were investigated. A total of 18 six-month-old Hu sheep were divided into small group (S, with left testis weight < 50 g), medium group (M, with left testis weight among 90-110 g), and large group (L, with left testis weight >160 g), which had six individuals each. The expression of PLA in testicular tissues of different sizes was analyzed by immunohistochemistry, RT-qPCR, and Western blot.

The retinal pigment epithelium: Functions and roles in ocular diseases.

The retinal pigment epithelium (RPE) between retinal photoreceptors and choroidal capillaries is a single layer of cells that are of critical importance to the eye. RPE cells are derived from the anterior neural plate of neuroectodermal origin. Instructed by specific molecules and signaling pathways, the RPE undergoes formation and maturation to form a functional unit together with photoreceptors.

Heritability and recursive influence of host genetics on the rumen microbiota drive body weight variance in male Hu sheep lambs.

Background: Heritable rumen microbiota is an important modulator of ruminant growth performance. However, no information exists to date on host genetics-rumen microbiota interactions and their association with phenotype in sheep. To solve this, we curated and analyzed whole-genome resequencing genotypes, 16S rumen-microbiota data, and longitudinal body weight (BW) phenotypes from 1150 sheep.

iTRAQ-based proteomic analysis provides novel insight into the postnatal testicular development of Hu sheep.

Testicular development is an intricate and coordinated process in which thousands of proteins are involved in the regulation of somatic cells development and spermatogenesis. However, knowledge about the proteomic changes during postnatal testicular development in Hu sheep is still elusive. The study was conducted to characterize the protein profiles at four key stages during postnatal testicular development, including infant (0-month-old, M0), puberty (3-month-old, M3), sexual maturity (6-month-old, M6) and body maturity (12-month-old, M12), and between the large- and small-testis groups at 6 months in Hu sheep.

Region-Controlled Framework Interface Mediated Anion Exchange Chemical Transformation to Designed Metal Phosphosulfide Heteronanostructures.

Postsynthetic chemical transformation provides a powerful platform for creating heteronanostructures (HNs) with well-defined materials and interfaces that generate synergy or enhancement. However, it remains a synthetic bottleneck for the precise construction of HNs with increased degrees of complexity and more elaborate functions in a predictable manner. Herein, we define a general transformative protocol for metal phosphosulfide HNs based on tunable hexagonal CuS frameworks with corner-, edge- and face-controlled growth of CoP domains.

PDGF-D-induced immunoproteasome activation and cell-cell interactions.

Platelet-derived growth factor-D (PDGF-D) is abundantly expressed in ocular diseases. Yet, it remains unknown whether and how PDGF-D affects ocular cells or cell-cell interactions in the eye. In this study, using single-cell RNA sequencing (scRNA-seq) and a mouse model of PDGF-D overexpression in retinal pigment epithelial (RPE) cells, we found that PDGF-D overexpression markedly upregulated the key immunoproteasome genes, leading to increased antigen processing/presentation capacity of RPE cells.
