Regulation of Cydia pomonella in the Northern German climate

Population control of the codling moth (Cydia pomonella) is of great importance in ecological fruit-growing. In the work described here we attempted (1) to determine the efficacy of plant protection preparations certified for organic fruit production, and (2) to develop a suitable application strategy. We found that a Granulovirus (Madex3), Bacillus thuringiensis (Xentari) and Neem Azal were able to provide effective control of C. pomonella. The reduced efficacy of Madex 3 as reported e.g. from some Southern German orchards could not be observed in our trials

Rapid return for school refusal: A school-based approach applied with Japanese adolescents

Cognitive behavioral therapy (CBT) is often effective in the treatment of school refusal (SR). Its usefulness is limited, however, if youth displaying SR also refuse to attend treatment sessions. In these cases parents and school staff may consider using school-based interventions that do not rely on face-to-face assessment and treatment with the young person. The current study examined the effectiveness of a school-based intervention applied in Japan to achieve rapid return to school among adolescents displaying SR. Between 2009 and 2015, the parents of 62 adolescents displaying SR were invited to implement a school-based rapid return approach. Thirty-nine parents agreed to implement the approach and 23 decided to wait until their child spontaneously attended school. Of the 39 cases in which the approach was implemented, 28 adolescents (72%) resumed attendance at their original school, 2 (5%) transferred to another school, and 9 (23%) did not resume attendance. In contrast, all 23 non-intervention cases continued to refuse to attend school for 3 months or longer, and none of these adolescents returned to regular school attendance within 9 months. This study tentatively suggests that the rapid return approach may be an effective form of intervention for adolescents displaying SR and simultaneously refusing to attend individual therapy. Because this approach is ethically complex, involving forced school attendance in adolescence, it should only be employed under specific circumstances. These circumstances are discussed.Pathways through Adolescenc

Paternal Diet Defines Offspring Chromatin State and Intergenerational Obesity

The global rise in obesity has revitalized a search for genetic and epigenetic factors underlying the disease. We present a Drosophila model of paternal-diet-induced intergenerational metabolic reprogramming (IGMR) and identify genes required for its encoding in offspring. Intriguingly, we find that as little as 2 days of dietary intervention in fathers elicits obesity in offspring. Paternal sugar acts as a physiological suppressor of variegation, desilencing chromatin-state-defined domains in both mature sperm and in offspring embryos. We identify requirements for H3K9/K27me3-dependent reprogramming of metabolic genes in two distinct germline and zygotic windows. Critically, we find evidence that a similar system may regulate obesity susceptibility and phenotype variation in mice and humans. The findings provide insight into the mechanisms underlying intergenerational metabolic reprogramming and carry profound implications for our understanding of phenotypic variation and evolution

AEGIS at CERN: Measuring Antihydrogen Fall

The main goal of the AEGIS experiment at the CERN Antiproton Decelerator is the test of fundamental laws such as the Weak Equivalence Principle (WEP) and CPT symmetry. In the first phase of AEGIS, a beam of antihydrogen will be formed whose fall in the gravitational field is measured in a Moire' deflectometer; this will constitute the first test of the WEP with antimatter.Comment: Presented at the Fifth Meeting on CPT and Lorentz Symmetry, Bloomington, Indiana, June 28-July 2, 201

SGLT2 Inhibitors Correct Fluid Overload in Adult Kidney Transplant Recipients—A Prospective Observational Study

In this longitudinal observational study, we measured urinary glucose concentration, body composition and volume status (bioimpedance spectroscopy) and plasma renin and aldosterone concentrations in n = 22 kidney transplant recipients (KTRs) initiating on SGLT2I at baseline (BL), and after 1 week and 1, 3, and 6 months. Estimated glomerular filtration rate (eGFR) decreased by −2 mL/min/1.73 m2 (IQR −10–0) after 1 week and remained stable thereafter. Urinary glucose concentration was 10 (3–24) g/g creatinine after 1 week and correlated with eGFR (r2 = 0.273; p = 0.057). SGLT2I did not affect HbA1c, fasting blood glucose, body weight, fat or lean mass. SGLT2I decreased fluid overload dependent on baseline overhydration (OH, r2 = 0.54, p = 0.0003) without occurrence of dehydration. Plasma aldosterone increased at day 7, while plasma renin did not change significantly. In conclusion, SGLT2I corrected fluid overload in patients with elevated overhydration at baseline, while in euvolemic KTRs fluid status remained stable without reduction of body water below the reference range, thus promoting the safety of SGLT2I therapy in patients following kidney transplantation. Glucosuria, together with effects of SGLT2I on blood glucose control and body weight, is attenuated in KTRs dependent on eGFR

Ravulizumab in Atypical Hemolytic Uremic Syndrome: An Analysis of Two-Year Efficacy and Safety Outcomes in Two Phase 3 Trials

Rationale & Objective: Atypical hemolytic uremic syndrome (aHUS) is a rare form of thrombotic microangiopathy (TMA) caused by complement dysregulation. Ravulizumab is a complement C5 inhibitor (C5i) approved for the treatment of aHUS. This analysis assessed long-term outcomes of ravulizumab in adults and pediatric patients with aHUS. Study Design: This analysis reports 2-year data from two phase 3, single-arm studies. Setting & Participants: One study included C5i-naive adults (NCT02949128) and the other included two cohorts of pediatric patients (C5i-naive and those who switched to ravulizumab from eculizumab [pediatric switch patients]; NCT03131219). Exposure(s): Patients received intravenous ravulizumab every 4–8 weeks, with the dose depending on body weight. Outcomes: The primary endpoint in the studies of C5i-naive patients was complete TMA response, which consisted of platelet count normalization, lactate dehydrogenase normalization, and ≥25% improvement in serum creatinine from baseline, at two consecutive assessments at least 4 weeks apart. Analytical Approach: All analyses used descriptive statistics. No formal statistical comparisons were performed. Results: In total, 86 and 92 patients were included in efficacy and safety analyses, respectively. Complete TMA response rates over 2 years were 61% and 90% in C5i-naive adults and pediatric patients, respectively. The median increase in eGFR from baseline was maintained over 2 years in C5i-naive adults (35 mL/min/1.73m2 ) and pediatric patients (82.5 mL/min/1.73m2 ). Most adverse events and serious adverse events occurred during the first 26 weeks. No meningococcal infections were reported. Improvement in the Functional Assessment of Chronic Illness Therapy – Fatigue score achieved by 26 weeks was maintained over 2 years. Journal Pre-proof 3 Limitations: Limitations were the small sample of pediatric switch patients and limited availability of genetic data. Conclusions: Long-term treatment with ravulizumab is well tolerated and associated with improved hematological and renal parameters and quality of life in adults and pediatric patients with aHUS
