Universal Bound on Effective Central Charge and Its Saturation.

The effective central charge (denoted by c_{eff}) is a measure of entanglement through a conformal interface, while the transmission coefficient (encoded in the coefficient c_{LR} of the two-point function of the energy-momentum tensor across the interface) is a measure of energy transmission through the interface. It has been pointed out that these two are generally different. In this Letter, we propose the inequalities, 0≤c_{LR}≤c_{eff}≤min(c_{L},c_{R}).

Enhancing biohydrogen production from xylose at low temperature (20 °C) using natural FeS Ore: Thermodynamic analysis and mechanistic insights.

This study investigates the efficacy of pyrite in enhancing biohydrogen production from xylose at low temperature (20 °C). Higher hydrogen yield rates (R) and reduced lag time (λ) were achieved across initial xylose concentrations ranging from 2-10 g/L. At an optimal xylose concentration of 5 g/L, pyrite reduced λ by 2.

Enhancing biohydrogen production from xylose through natural FeS ore: Mechanistic insights.

In this study, we investigated the advantages of utilizing natural FeS ore in the context of dark fermentative hydrogen production within a fermentation system employing heat-treated anaerobic granular sludge with xylose as the carbon source. The results demonstrated a significant improvement in both hydrogen production and the maximum rate, with increases of 2.58 and 4.

A zebrafish NLRX1 isoform downregulates fish IFN responses by targeting the adaptor STING.

In mammals, NLRX1 is a unique member of the nucleotide-binding domain and leucine-rich repeat (NLR) family showing an ability to negatively regulate IFN antiviral immunity. Intron-containing genes, including NLRX1, have more than one transcript due to alternative splicing; however, little is known about the function of its splicing variants. Here, we identified a transcript variant of NLRX1 in zebrafish (Danio rerio), termed NLRX1-tv4, as a negative regulator of fish IFN response.

Zebrafish HERC7c Acts as an Inhibitor of Fish IFN Response.

In humans, four small HERCs (HERC3-6) exhibit differential degrees of antiviral activity toward HIV-1. Recently we revealed a novel member HERC7 of small HERCs exclusively in non-mammalian vertebrates and varied copies of genes in distinct fish species, raising a question of what is the exact role for a certain fish gene. Here, a total of four genes (named HERC7a-d sequentially) are identified in the zebrafish genome.

Yellow catfish RIO kinases (RIOKs) negatively regulate fish interferon-mediated antiviral response.

In mammals, right open reading frame kinases (RIOKs) are initially reported to participate in cancer cell proliferation, apoptosis, migration and invasion, and recently they have been related to host immune response. Little is known about the homologs of RIOKs in fish. In the current study, we cloned three homologous genes of RIOK family in yellow catfish (Pelteobagrus fulvidraco), termed Pfriok1, Pfriok2 and Pfriok3.

A finTRIM Family Protein Acquires RNA-Binding Activity and E3 Ligase Activity to Shape the IFN Response in Fish.

Tripartite motif (TRIM) family proteins have come forth as important modulators of innate signaling dependent on of E3 ligase activity. Recently, several human TRIM proteins have been identified as unorthodox RNA-binding proteins by RNA interactome analyses; however, their targets and functions remain largely unknown. FTRCA1 is a crucian carp ()-specific finTRIM (fish novel TRIM) member and negatively regulates the IFN antiviral response by targeting two retinoic acid-inducible gene-I (RIG-I)-like receptor (RLR) pathway molecules, that is, TANK-binding kinase 1 (TBK1) and IFN regulatory factor 7 (IRF7).

Function conservation and disparities of zebrafish and human LGP2 genes in fish and mammalian cells responsive to poly(I:C).

Retinoic acid inducible gene-I (RIG-I)-like receptors (RLRs) are viral RNA sensors that regulate host interferon (IFN)-mediated antiviral signaling. LGP2 (laboratory genetics and physiology 2) lacks the N-terminal caspase activation and recruitment domains (CARDs) responsible for signaling transduction in the other two RLR proteins, RIG-I and melanoma differentiation associated gene-5 (MDA5). How LGP2 regulates IFN signaling is controversial, and inconsistent results have often been obtained in overexpression assays when performed in fish cells and mammalian cells.

Zebrafish MARCH8 downregulates fish IFN response by targeting MITA and TBK1 for protein degradation.

Recent studies have related the membrane-associated RING-CH-type finger (MARCH) family proteins to host innate immune response. Zebrafish (Danio rerio) MARCH8 is reported to target SVCV glycoprotein for degradation; however, little is known about whether fish MARCH8 is involved in innate interferon (IFN) response. In this study, zebrafish march8 was significantly induced by SVCV infection.

Promoter Binding and Nuclear Retention Features of Zebrafish IRF Family Members in IFN Response.

Interferon regulatory factors (IRFs) constitute a family of transcription factors that synchronize interferon (IFN) antiviral response through translocating to nucleus and binding to the promoters of IFN and IFN-stimulated genes (ISGs). Fish contain 11 IRF members; however, whether or how fish IRF family genes function in IFN response remains limited. Herein, we determine the regulatory roles of 11 zebrafish IRF family members in IFN response relevant to their subcellular localization and promoter binding.

Deep diamond single-photon sources prepared by a femtosecond laser.

Nitrogen-vacancy color centers (NVs) in diamond have several potential applications ranging from quantum computing to data storage. However, artificial NVs are often close to the surface, which limits their spatial density and applicability. Here we demonstrate an effective and precise method for preparing deep single NVs in diamond.

The ameliorating effects of Bushen Tiaoxue Granules and Kunling Wan on impaired angiogenesis and endometrial receptivity in rats following controlled ovarian hyperstimulation.

Objective: To investigate the effects of Bushen Tiaoxue Granules and Kunling Wan, the two Chinese medicines, on vascular dysfunction and the impairment of endometrial receptivity caused by controlled ovarian hyperstimulation and its underlying mechanism.

Methods: Female Sprague Dawley rats with regular estrous cycle were enrolled and given Bushen Tiaoxue Granules or Kunling Wan by gavage for 12 days, and then, controlled ovarian hyperstimulation model was induced. We assessed endometrial microvessels, endometrial blood flow, levels of estradiol and progesterone in serum, vascular endothelial growth factor A upstream molecules estrogen and progesterone receptors in the endometrium, and pregnancy outcome.

Xiao-Yao-San, a Chinese Medicine Formula, Ameliorates Chronic Unpredictable Mild Stress Induced Polycystic Ovary in Rat.

Chronic stress induces endocrine disturbance, which contributes to the development of polycystic ovary syndrome (PCOS), a condition that remains a challenge for clinicians to cope with. The present study investigated the effect of Xiao-Yao-San (XYS), a traditional Chinese medicine formula used for treatment of gynecological disease, on the chronic stress-induced polycystic ovary and its underlying mechanism. Female Sprague-Dwaley rats underwent a 3 weeks chronic unpredictable mild stress (CUMS) procedure to establish the PCOS model, followed by 4 weeks treatment with XYS (0.

Silibinin Capsules improves high fat diet-induced nonalcoholic fatty liver disease in hamsters through modifying hepatic de novo lipogenesis and fatty acid oxidation.

Ethnopharmacological Relevance: Silibinin Capsules (SC) is a silybin-phospholipid complex with silybin as the bioactive component. Silybin accounts for 50-70% of the seed extract of Silybum marianum (L.) Gaertn.

Catalpol restores LPS-elicited rat microcirculation disorder by regulation of a network of signaling involving inhibition of TLR-4 and SRC.

LPS-induced microvascular hyperpermeability and hemorrhage play a key role in the development of sepsis, the attenuation of which might be an important strategy to prevent sepsis. However, the current clinical therapies have proven to be inefficient in improving the prognosis for patients with sepsis. Catalpol, an iridoid glycoside extracted from the roots of Rehmannia, has been reported to protect against LPS-induced acute lung injury through a Toll-like receptor-4 (TLR-4)-mediated NF-κB signaling pathway.

STAT1 contributes to dsRNA inhibition of liver regeneration after partial hepatectomy in mice.

Increasing evidence suggests that liver regeneration is suppressed in patients with chronic HCV infection; however, the underlying mechanisms remain unclear. Previously, we demonstrated that injection of the synthetic double-stranded RNA (dsRNA) poly I:C to mimic viral infection suppresses liver regeneration in the partial hepatectomy (PHx) model, whereby IFN-gamma contributes to the inhibition. In this study, we examined the role of the IFN-gamma-activated downstream signal (STAT1) and genes (IRF-1, p21(cip1), and SOCS1) in liver regeneration and hepatocyte proliferation.
