Emodin exhibits antioxidative functions in the central nervous system (CNS); however, its neuroprotective mechanism against fluoride remains to be elucidated. Selleck PMA activator Our aim was to explore the neuroprotective efficacy and the possible mechanisms of emodin. In our study, synaptic proteins and oxidative stress damage were examined after human neuroblastoma SH-SY5Y cells were treated with high doses of NaF for 24 hours. Moreover, pretreatment with emodin was used to shed light on the neuroprotective effects in NaF-induced toxicity in SH-SY5Y cells. We found that NaF significantly lowered the protein expressions of SNAP 25, synaptophysin and PSD 95 in SH-SY5Y cells. In addition, NaF exposure increased the protein expression of p-ERK1/2 and decreased the protein expressions of Nrf2 and HO-1, as well as facilitated increasing ROS, 4-hydroxynonenal (4-HNE), and 8-Hydroxy-2'-deoxyguanosine (8-OHdG). Pretreatment with emodin significantly recovered these alterations caused by NaF. These data implied that the neuroprotective effects of emodin and pointed to the promising utilization for protecting against neurotoxicity induced by fluoride. © 2020 Wiley Periodicals, Inc.Photocatalytic hydrogen evolution is viewed as a promising green strategy to utilize the inexhaustible solar energy and provide clean hydrogen fuels with zero-emission characteristic. The nature of semiconductor-based photocatalysts is the key point to achieve efficient photocatalytic hydrogen evolution. Conjugated materials have been recently emerging as a novel class of photocatalysts for hydrogen evolution and photocatalytic reactions due to their electronic properties can be well controlled via tailor-made chemical structures. Hydrophilic conjugated materials, a subgroup of conjugated materials, possess multiple advantages for photocatalytic applications, thus spurring remarkable progress on both material realm and photocatalytic applications. This mini-review aims to provide a brief review of the recent developments of hydrophilic conjugated polymers/small molecules for photocatalytic applications, and special concern on the rational molecular design and their impact on photocatalytic performance will be reviewed. Perspectives on the hydrophilic conjugated materials and challenges to their applications in photocatalytic field are also presented. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Classic Menkes disease is a rare X-linked recessive disorder of copper metabolism caused by pathogenic variants in the copper transporter gene, ATP7A. Untreated affected individuals suffer failure to thrive and neurodevelopmental delays that begin at 6-8 weeks of age and progress inexorably to death, often within 3 years. Subcutaneous injections of Copper Histidinate (US Food and Drug Administration IND #34,166, Orphan product designation #12-3663) are associated with improved survival and neurological outcomes, especially when commenced within a month of birth. We previously identified internal jugular vein phlebectasia (IJP) in four Menkes disease subjects. This feature and other connective tissue abnormalities appear to be consequences of deficient activity of lysyl oxidase, a copper-dependent enzyme. Here, we report results from a prospective study of IJP based on 178 neck ultrasounds in 66 Menkes subjects obtained between November 2007 and March 2018. Nine patients met the criterion for IJP (one or more cross-sectional area measurements exceeding 2.2 cm2 ) and five subjects had clinically apparent neck masses that enlarged over time. Our prospective results suggest that IJP occurs in approximately 14% (9/66) of Menkes disease patients and appears to be clinically benign with no specific medical or surgical actionability. We surveyed the medical literature for prior reports of IJP in pediatric subjects and identified 85 individuals and reviewed the distribution of this abnormality by gender, sidedness, and underlying etiology. Taken together, Menkes disease accounts for 16% (15/94) of all reported IJP individuals. Neck masses from IJP represent underappreciated abnormalities in Menkes disease. © 2020 Wiley Periodicals, Inc.Germ cell development is essential for maintaining reproduction in animals. In postpubertal females, oogenesis is a highly complicated event for producing fertilizable oocytes. It starts when dormant primordial oocytes undergo activation to become growing oocytes. In postpubertal males, spermatogenesis is a differentiation process for producing sperm from spermatogonial stem cells. To obtain full understanding of the molecular mechanisms underlying germ cell development, the Cre/loxP system has been widely applied for conditional knock-out mouse studies. In this study, we established a novel knock-in mouse line, B6-Ddx4 em1(CreERT2)Utr , which expresses CreERT2 recombinase under the control of the endogenous DEAD-box helicase 4 (Ddx4) gene promoter. Ddx4 was specifically expressed in both female and male germ cell lineages. We mated the CreERT2 mice with R26GRR mice, expressing enhanced green fluorescent protein (EGFP) and tDsRed before and after Cre recombination. We found tDsRed signals in the testes and ovaries of tamoxifen-treated B6-Ddx4 em1(CreERT2)Utr R26GRR mice, but not in untreated mice. Immunostaining of their ovaries clearly showed that Cre recombination occurred in all oocytes at every follicle stage. We also found 100% Cre recombination efficiency in male germ cells via the progeny test. In summary, our results indicate that B6-Ddx4 em1(CreERT2)Utr is beneficial for studying female and male germ cell development. © 2020 Wiley Periodicals, Inc.INTRODUCTION Turoctocog alfa pegol is a glycoPEGylated recombinant factor VIII (FVIII) with an extended half-life developed for prophylaxis, treatment of bleeds and perioperative management in patients with haemophilia A. AIM Evaluate the efficacy and safety of turoctocog alfa pegol treatment for major and minor surgeries in the pathfinder 3 and 5 phase III trials. METHODS Adults/adolescents aged ≥12 years with severe haemophilia A (FVIII 80% during major surgery (pathfinder 3). The primary end point was haemostatic efficacy during surgery; secondary end points were blood loss, haemostatic effect postsurgery, consumption, transfusions, safety and health economics. Children (0-11 years) undergoing minor surgeries received 20-75 IU/kg turoctocog alfa pegol at Investigator's discretion (pathfinder 5). RESULTS pathfinder 3 included 35 patients undergoing 49 major surgeries. Haemostasis was successful in 47/49 (95.9%) surgeries; two had moderate haemostatic responses. Median (mean) blood loss during major surgery was 75 (322.
