0% (ceramic restoration, N = 23)-differed significantly in the regression analysis. CONCLUSIONS Conventional restorations were associated with moderate-to-high survival rates in MIH teeth. In contrast, non-invasive composite restorations, which were predominately used in younger or less cooperative children, were linked to lower survival rates. © 2020 BSPD, IAPD and John Wiley & Sons A/S.

Alcohol is associated with a range of effects on the central nervous system at different doses and acts on a number of receptors. Acute disorders include Wernicke's encephalopathy (WE), traumatic brain injury, blackouts, seizures, stroke and hepatic encephalopathy. The most common manifestations of chronic alcohol consumption are Korsakoff's syndrome (KS) and alcohol-related dementia (ARD). There is limited evidence for benefit from memantine in the treatment of ARD, but stronger evidence for the use of high-dose parenteral thiamine in the progression of neuropsychiatric symptoms for WE. Accumulating evidence exists for pharmacological treatment in the prevention of hepatic encephalopathy. Rehabilitation of people with ARD may take several years, and requires an approach that addresses physical and psychosocial factors. © 2020 Society for the Study of Addiction.OBJECTIVE To investigate cerebral anomalies other than Chiari type 2 malformation in fetuses with myelomeningocele (MMC). DESIGN A retrospective cohort study in a single tertiary centre. SETTING A review of associated cerebral anomalies in cases with prenatal diagnosis of myelomeningocele. POPULATION Seventy cases of fetal myelomeningocele. METHODS Ultrasound and MRI images were blindly reviewed. this website Postnatal imaging and results of the postmortem results were also reviewed. The association between cerebral anomalies and the following ultrasound findings was measured level of the defect, ventriculomegaly, microcephaly and fetal talipes. MAIN OUTCOME MEASURES A microcephaly was observed in 32/70 cases (46%) and a ventriculomegaly was observed in 39/70 cases (56%). Other cerebral anomalies were diagnosed in 47/70 (67%). RESULTS Other cerebral anomalies were represented by 42/70 cases with abnormal CC (60%), 8/70 cases with perinodular heterotopia (PNH; 11%), 2/70 cases with abnormal gyration (3%). MRI performed only in fetal surgery cases confirmed the ulltrasound findings in all cases and provided additional findings in two cases (PNH). Risk ratios of fetal cerebral anomalies associated with MMC did not reach significance for microcephaly, ventriculomegaly, talipes or the level of the defect There was an overall good correlation between pre- and postnatal findings with a Kappa value of 0.79 [95% CI 0.57-1] and 82% agreement. CONCLUSION Fetal brain anomalies other than Chiari type 2 malformation are frequently observed in fetuses with myelomeningocele, predominantly represented by CC anomalies. Whether these associated cerebral anomalies have an impact on selecting cases eligible for fetal surgery needs further evaluation. TWEETABLE ABSTRACT Fetal cerebral anomalies other than Chiari type 2 malformation, microcephaly, and ventriculomegaly may be associated with MMC in up to 67% of the cases. © 2020 Royal College of Obstetricians and Gynaecologists.BACKGROUND RNA interference (RNAi) is a potential tool for plant protection against insect pests. The great challenge for effective pest control using RNAi in the field is the development of efficient and reliable methods for the production and delivery of double-stranded RNA (dsRNA). RESULTS In the present study, we investigated the potential of feeding in vitro synthesized or bacterially expressed dsRNA to populations of the 28-spotted ladybeetle Henosepilachna vigintioctopunctata as a method of biological pest control. Ingestion of in vitro synthesized dsHvRPS18 or dsHvRPL13 led to significant down-regulation of the ribosomal protein-encoding genes HvRPS18 and HvRPL13, respectively, and significantly decreased the survival of H. vigintioctopunctata. Such silencing of HvRPS18 or HvRPL13 expression appeared to be partially dose-dependent and also inhibited the growth of H. vigintioctopunctata and significantly suppressed the expression of digestive enzyme-related genes. Finally, ingestion of bacterially expressed dsHvRPS18 or dsHvRPL13 induced significant mortality in the first and third instars, and in adults. CONCLUSION The effectiveness of RNAi-based gene silencing in H. vigintioctopunctata provides a powerful reverse genetic tool for the functional annotation of its genes. This study demonstrates that HvRPS18 and HvRPL13 represent candidate genes for RNAi-based biological control of H. vigintioctopunctata. © 2020 Society of Chemical Industry. © 2020 Society of Chemical Industry.Alternariol and altenuisol were isolated as the major phytotoxins produced by an Alternaria sp. pathogenic fungus of the invasive weed Xanthium italicum. Altenuisol exhibited stronger phytotoxic effect compared with alternariol. At 10 μg/mL, alternariol and altenuisol promoted root growth of the monocot plant Pennisetum alopecuroides by 11.1 % and 75.2 %, respectively, however, inhibitory activity was triggered by the increase of concentration, with root elongation being suppressed by 35.5 % and 52.0 % with alternariol and altenuisol at 1000 μg/mL, respectively. Alternariol slightly inhibited root length of the dicot plant Medicago sativa at 10-1000 μg/mL, whereas altenuisol stimulated root growth by 51.0 % at 10 μg/mL and inhibited root length by 43.4 % at 200 μg/mL. Alternariol and altenuisol did not exert strong regulatory activity on another dicot plant, Amaranthus retroflexus, when tested concentration was low, however, when the concentration reached 1000 μg/mL, they reduced root length by 68.1 % and 51.0 %, respectively. Alternariol and altenuisol exerted similar effect on shoot growth of three tested plants but to a lesser extent. It is noteworthy to mention that this is the first report on the phytotoxicity of altenuisol. © 2020 Wiley-VHCA AG, Zurich, Switzerland.
