The Effect of Mulberry Silage Supplementation on the Carcass Fatness and Long-Chain Fatty Acid Composition of Growing Lambs Compared with Traditional Corn Silage.

Lamb meat has become very popular with consumers in recent years due to its nutritional benefits. As a lean red meat, lamb is an important natural source of polyunsaturated and saturated fatty acids, which can be modified by adjustments in livestock feed. This study used proteomic and metabolic analyses to compare a basal ration supplemented with either mulberry silage or corn silage.

Regulatory role of N6-Methyladenosine on skeletal muscle development in Hu sheep.

N6-Methyladenosine (m6A) RNA modification plays an essential role in many biological processes. To investigate the regulatory role of m6A on the skeletal muscle development in Hu sheep, this study took newborn Hu sheep (b_B Group) and six-month-old Hu sheep (s_B Group) as the objects. MeRIP-seq and RNA-Seq analysis techniques were used to detect differentially methylated genes (DMGs) and differentially expressed genes (DEGs) in the longissimus dorsi muscle of Hu sheep at different months of age.

Primary Plasmablastic Lymphoma of The Paranasal Sinuses: A Rare Case Report.

Plasmablastic lymphoma (PBL) is a rare and highly invasive type of non-Hodgkin's lymphoma. It is usually associated with immunosuppression and human immunodeficiency virus infection. PBL most commonly occurs in the oral cavity, lymph nodes, and in other extranodal sites.

Dried tea residue can alter the blood metabolism and the composition and functionality of the intestinal microbiota in Hu sheep.

Ruminant animals face multiple challenges during the rearing process, including immune disorders and oxidative stress. Green tea by-products have gained widespread attention for their significant immunomodulatory and antioxidant effects, leading to their application in livestock production. In this study, we investigated the effects of Dried Tea Residue (DTR) as a feed additive on the growth performance, blood biochemical indicators, and hindgut microbial structure and function of Hu sheep.

Proteome changes of dairy calves rumen epithelium from birth to postweaning.

Rumen epithelium plays a central role in absorbing, transporting, and metabolizing of short-chain fatty acids. For dairy calves, the growth of rumen papillae greatly enhances the rumen surface area to absorb nutrients. However, the molecular mechanism underlying dairy calves rumen postnatal development remains rarely understood.

Transcript variants of long-chain acyl-CoA synthase 1 have distinct roles in sheep lipid metabolism.

Mutton has recently been identified to be a consumer favorite, and intermuscular fat is the key factor in determining meat tenderness. Long-chain acyl-CoA synthetase 1 (ACSL1) is a vital subtype of the ACSL family that is involved in the synthesis of lipids from acyl-CoA and the oxidation of fatty acids. The amplification of the ACSL1 gene using rapid amplification of cDNA ends revealed that the alternative polyadenylation (APA) results in two transcripts of the ACSL1 gene.

Proteome changes of sheep rumen epithelium during postnatal development.

The development of the rumen epithelium is a critical physiological challenge for sheep. However, the molecular mechanism underlying postnatal rumen development in sheep remains rarely understood. Here, we used a shotgun approach and bioinformatics analyses to investigate and compare proteomic profiles of sheep rumen epithelium tissue on day 0, 15, 30, 45, and 60 of age.

Proteomic and parallel reaction monitoring approaches to evaluate biomarkers of mutton tenderness.

Intensive fattening usually results in the changes of meat quality. Tenderness is a central attribute for mutton sensory qualities and consumers' choice. Here, we reported that intensive fattening mutton was more tender than that of traditionally raised sheep.

The involvement of translationally controlled tumor protein during lamb rumen epithelium development.

Early weaning is usually applied to improve the reproductive efficiency of sheep in mutton production, while the development of rumen is of vital importance for sheep weaning age. Translationally controlled tumor protein (TCTP) is a highly conserved protein which participates in multiple tissue and organ development. Thus, we hypothesized that TCTP was involved in sheep rumen development.

The RyR-Cl -VDCC axis contributes to spontaneous tone in urethral smooth muscle.

Current therapies including pharmaceutical intervention and surgery have limited efficacy on stress urinary incontinence (SUI). One type of SUI is due to low intraurethral pressure caused by the disabled contraction of urethral smooth muscle (USM). However, the molecular mechanisms underlying the motility of USM remain unknown.

A novel method to detect meat adulteration by recombinase polymerase amplification and SYBR green I.

Meat adulteration is one of the most common economic fraudulences in food industry. Current methodologies of meat source identification are complex, time-consuming and require sophisticated equipment. Hence, a simpler species specific method to determinate species is urgently needed.

Mitigation of stress from gastric mucosal injuries by mulberry extract may occur via nitric oxide synthase signaling in mice.

Acute gastric mucosal injuries are serious clinical problems worldwide and are principally found with different types of stresses in animals. A constant challenge is to find original plant products that can combat stress. In the present study, we examined the effects of big-leaf mulberry extracts on stomach injury, and the activity of nitric oxide synthases (NOS) and total antioxidant activity (TAO) in the gastric mucosae of mice during water immersion and restraint stress (WIRS).

Contemporaneous effects of diabetes mellitus and hypothyroidism on spermatogenesis and immunolocalization of Claudin-11 inside the seminiferous tubules of mice.

Background: Diabetes and hypothyroidism produce adverse effects on body weight and sexual maturity by inhibiting body growth and metabolism. The occurrence of diabetes is always accompanied with thyroid dysfunction. Thus, it is important to take hypo- or hyper-thyroidism into consideration when exploring the adverse effects caused by diabetes.

Protective roles of Rutin against restraint stress on spermatogenesis in testes of adult mice.

In order to investigate the effects of Rutin against restraint stress, 50 adult male mice were divided into five groups: control, restraint stress (RS), and RS with 2 doses of Rutin treatments. Mice were restrained in a conical tube for 4 h daily and Rutin was injected intraperitoneally for 15 consecutive days. Restraint stress significantly decreases body weights, testis and epididymis weights, thymus weights, visceral fats, serum concentrations of testosterone, sperm counts, sperm motility and sperm viability, while it increases serum epinephrine levels, adrenal gland weights and abnormal sperms.

Thyroid hormones alter estrous cyclicity and antioxidative status in the ovaries of rats.

To expand our understanding of the roles of thyroid hormones on female reproduction, we induced hypo- and hyper-T rat models to investigate the roles of thyroid hormones on estrous cyclicity, as well as the antioxidative status in the ovaries of rats. In the current study, our data show that hypothyroidism (hypo-T) and hyperthyroidism (hyper-T) led to significantly reduced body weights and ovarain weights and delayed vaginal opening day. For hyper-T, thyroxine (T4), tri-iodothyronine (T3), progesterone (P4) and follicle-stimulating hormone (FSH) were significantly increased, while estradiol (E2) and luteinizing hormone (LH) were significantly decreased.

Nitric oxide and thyroid hormone receptor alpha 1 contribute to ovarian follicular development in immature hyper- and hypo-thyroid rats.

Thyroid dysfunction can cause ovarian cycle and ovulatory disturbances, however, the molecular link(s) between these two disorders remains largely unknown. In the current study, we examined the roles of nitric oxide synthase (NOS) and thyroid hormone receptor alpha 1 (TRα1) in these disorders using immature hyper-thyroid (hyper-T) and hypo-thyroid (hypo-T) rats. In comparison to controls, hyper-T rats had higher serum concentrations of triiodothyronine (T3) and thyroxine (T4), whereas hypo-T rats had lower serum T3 and T4.

Protective effects of Big-leaf mulberry and physiological roles of nitric oxide synthases in the testis of mice following water immersion and restraint stress.

Big-leaf mulberry is a new hybrid plant from the application of cell engineering technology, but its effect in stress-induced testicular dysfunction is unknown. Nitric oxide (NO) is a tiny, highly reactive lipophilic molecule produced by nitric oxide synthases (NOS). Three isoforms of NOS (neuronal NOS, inducible NOS and endothelial NOS) have been identified.

Roles of thyroid hormones in follicular development in the ovary of neonatal and immature rats.

Thyroid hormones (TH) play a critical role in ovarian follicular development, maturation and the maintenance of various endocrine functions. However, whether TH can affect ovarian follicular development in neonatal and immature rats remains unclear. Therefore, the aim of the present study was to elucidate the effect of TH on ovarian follicular development in neonatal and immature rats.
