Traditional Chinese Medicine formula Dai-Zong-Fang alleviating hepatic steatosis in mice via gut microbiota modulation.

Hepatic steatosis is a hepatic pathological change closely associated with metabolic disorders, commonly observed in various metabolic diseases such as metabolic syndrome (MetS), with a high global prevalence. Dai-Zong-Fang (DZF), a traditional Chinese herbal formula, is widely used in clinical treatment for MetS, exhibiting multifaceted effects in reducing obesity and regulating blood glucose and lipids. This study aims to explore the mechanism by which DZF modulates the gut microbiota and reduces hepatic steatosis based on the gut-liver axis.

The Chinese herbal medicine Dai-Zong-Fang promotes browning of white adipocytes and by activating PKA pathway to ameliorate obesity.

The global prevalence of obesity is rising rapidly. Conversion of white adipose tissue (WAT) into beige adipose tissue with heat-consuming characteristics, i.e.

Comparison of Three-Dimensional Navigation-Guided Percutaneous Iliosacral Screw and Minimally Invasive Percutaneous Plate for the Treatment of Zone II Unstable Sacral Fractures.

Objective: The percutaneous IS screws and the minimally invasive percutaneous plate are the most popular internal methods for Zone II unstable sacral fractures. However, the choice of fixation remains controversial for orthopaedic surgeons. The purpose of study was to evaluate and compare the clinical results of percutaneous iliosacral (IS) screw fixation under three-dimensional (3D) navigation and minimally invasive percutaneous plate fixation in the treatment of Zone II unstable sacral fractures.

[Effects of dezocine on cardiac myocytes injury induced by hypoxia and reoxygenation in rats and its mechanism].

To investigate the mechanisms of dezocine on regulating H9C2 oxidative stress and apoptosis of rat cardiac myocytes induced by hypoxia-reoxygenation(H/R) by regulating the expressions of microRNA-7a- 5p(miR-7a-5p)/ubiquitin E3 ligase tripartite motif 10(TRIM10).

Regulation of follicular development and differentiation by intra-ovarian factors and endocrine hormones.

Primordial germ cell migration and homing within the gonadal ridge during early embryo development requires oocyte-secreted polypeptide, growth factors, growth and differentiation factors (GDFs), bone morphogenetic proteins, stem cell factor (SCF), and basic fibroblast growth factor (bFGF). During embryogenesis, the germ cells migrate into developing gonads and undergo intra-ovarian development which involves the contact of primordial germ cells with other cells. Further follicular development and differentiation is tightly regulated by hormones and by intraovarian regulators.

Recent advances in the regulation of testicular germ cell tumors by microRNAs.

Testicular germ cell tumors (TGCTs) are generally rare but represent the most common solid tumors in young men. They are classified broadly into seminoma, which resemble primordial germ cells (PGCs), and non-seminoma, which are either undifferentiated (embryonic carcinoma) or differentiated (teratoma, yolk sac tumor, choriocarcinomas) patterning. A widespread role for microRNAs (miRNAs), in diverse molecular processes driving initiation and progression of various types of TGCTs has been recently studied.

Effects of sperm proteins on fertilization in the female reproductive tract.

Mammalian fertilization that culminates by fusion of the male and female gametes is intricately regulated within the female reproductive tract. To become competent to fertilize an egg, the mammalian spermatozoa that enter the female reproductive tract must undergo a series of physiological changes, including hyperactivation, and capacitation. For reaching full competency, the acrosome, a specialized membrane-bound organelle that covers the anterior part of the sperm head, must undergo an acrosome reaction.

Sperm DNA fragmentation index, as measured by sperm chromatin dispersion, might not predict assisted reproductive outcome.

Objective: Routine semen parameters have limited clinical diagnostic value for predicting male infertility. The aim of this study was to investigate the association between sperm DNA fragmentation index (DFI) and semen quality, and between DFI and clinical pregnancy rate of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).

Methods And Materials: A total of 390 couples undergoing sperm fragmentation prior to receiving conventional IVF (n = 238) or ICSI (n = 152) were evaluated.

Methods: Four and 8 weeks (n=18) after TDSCs, PRP, PRP with TDSC or PBS (control) injection into collagenase or saline (sham) injected rat Achilles tendon, tendon tissue was harvested and tendon quality was evaluated by histology and biomechanical testing.

miR-135a modulates tendon stem/progenitor cell senescence via suppressing ROCK1.

Tendon stem/progenitor cell (TSPC) senescence may lead to age-related tendon disorders and impair tendon regeneration and replacement capacity in humans. However, the mechanisms governing TSPC aging and degeneration remain obscure. Recently, it has been reported that Rho-associated coiled-coil protein kinase 1 (ROCK1) might be a key player in TSPC aging process.

Profiling the RNA editomes of wild-type C. elegans and ADAR mutants.

RNA editing increases transcriptome diversity through post-transcriptional modifications of RNA. Adenosine deaminases that act on RNA (ADARs) catalyze the adenosine-to-inosine (A-to-I) conversion, the most common type of RNA editing in higher eukaryotes. Caenorhabditis elegans has two ADARs, ADR-1 and ADR-2, but their functions remain unclear.

Clinical effectiveness analysis of dextran 40 plus dexamethasone on the prevention of fat embolism syndrome.

This study aims to investigate the clinical efficacy of Dextran 40 plus dexamethasone on the prevention of fat embolism syndrome (FES) in high-risk patients with long bone shaft fractures. According to the different preventive medication, a total of 1837 cases of long bone shaft fracture patients with injury severity score (ISS) > 16 were divided into four groups: dextran plus dexamethasone group, dextran group, dexamethasone group and control group. The morbidity and mortality of FES in each group were analyzed with pairwise comparison analysis.

Four new sesquiterpenes from the stems of Pogostemon cablin.

Four new sesquiterpenes (1-4), together with four known compounds (5-8), were isolated from the stems of Pogostemon cablin (Blanco.) Benth. Their chemical structures were elucidated by means of spectroscopic methods, including 1D and 2D NMR, HRESIMS, IR, and UV.

miR-16 inhibits cell proliferation by targeting IGF1R and the Raf1-MEK1/2-ERK1/2 pathway in osteosarcoma.

Several miRNAs have been implicated in the development and progression of osteosarcoma (OS). In this study, we found that miR-16 is downregulated in OS cell lines and tissues. Overexpression of miR-16 suppresses OS cell proliferation and tumor growth in nude mice.

Serine protease and ovarian paracrine factors in regulation of ovulation.

The controlled target extracellular matrix (ECM) degradation generated by serine protease and regulated by serine protease inhibitor and ovarian paracrine/autocrine factors is an event that affects a wide variety of physiological and pathological processes in the ovary. Evidence cumulated in the past decade clearly showed that the hormone-induced coordinated expression of the tissue-type PA (tPA) produced mainly by granulosa cells and oocyte, and its inhibitor PAI-1 secreted by theca cells in the preovulatory follicles may be responsible for a controlled and directed proteolysis leading to the rupture of selected follicles in the rat, monkey and other mammals. In recent years increasing evidence further demonstrated that oocyte maturation and ovulation may also be modulated by other serine protease and inhibitor, as well as endogenously- produced ovarian paracrine/autocrine factors.
