Results The ALDHi 673A cellular accumulation of toxic aldehydes which induce DNA double strand breaks. This is exacerbated by addition of exogenous aldehydes such as vitamin-A (retinaldehyde) and ameliorated by aldehyde scavengers such as metformin and hydralazine. Importantly, ALDH1A3 knockout cells demonstrated increased sensitivity to ATM/ATR inhibitors. And, ALDHi synergized with inhibitors of ATM and ATR, master regulators of the DSB DNA damage response, both in vitro and in vivo. This synergy was evident in homologous recombination (HR) proficient cell lines. Conclusions ALDHi can be used to induce DNA DSB in cancer cells and synergize with inhibitors the ATM/ATR pathway. Our data suggest a novel therapeutic approach to target HR proficient ovarian cancer cells.Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the ECONASE ® XT, an enzyme based on endo-1,4-β-xylanase produced by a genetically modified strain of Trichoderma reesei CBS 114044. The additive is currently authorised for use in chickens for fattening, chickens reared for laying, laying hens, turkeys for fattening, turkeys reared for breeding, minor poultry species, piglets (weaned) and pigs for fattening. ECONASE ® XT is currently authorised in two forms, a solid and a liquid form with activities of 4,000,000 and 400,000 BXU/g, respectively. In a previous opinion, the FEEDAP Panel could not exclude the potential presence of recombinant DNA derived from the production organism in recent batches of the additive. The applicant has submitted data to support the absence of recombinant DNA derived from the production organism in recent product batches. The FEEDAP Panel confirms that the data provided support the absence of recombinant DNA of Trichoderma reesei CBS 114044 in the additive and thus, no safety concern was identified.In accordance with Article 6 of Regulation (EC) No 396/2005, the applicants BASF Agro B.V. (represented by OAT Agrio Co. Ltd.) and Certis Europe B.V. submitted separate requests to the competent national authority in the Netherlands to modify the existing maximum residue levels (MRLs) for the active substance cyflumetofen in various crops. The data submitted in support of the requests were found to be sufficient to derive MRL proposals for citrus fruits, apricots, peaches, tomatoes, aubergines, cucumbers and hops. Adequate analytical methods for enforcement are available to control the residues of cyflumetofen on the fruit commodities under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg and on hops at the LOQ of 0.1 mg/kg. Based on the risk assessment results, EFSA concluded that the long-term intake of residues resulting from the use of cyflumetofen according to the reported agricultural practices is unlikely to present a risk to consumer health.This is a general factsheet about COVID-19. It has some specific information for people with lung conditions, but most of the information will apply to everybody.Breathe is voluntarily reviewed. We are most grateful to the hard work and dedication of those listed below, who reviewed articles for Breathe in 2020.A new "traffic light" system is recommended to identify adult NMD patients who would benefit from advance care planning and possible referral to palliative care services https//bit.ly/3mVDY0P.#ERSCongress 2020 best-abstract awardees summarise their virtual European Respiratory Society International Congress experience and views on the evolving field of research for their respective assembly https//bit.ly/3kJ9JrJ.Health inequalities regarding gender are extremely prevalent, and specifically in conditions such as COPD. No woman should ever be dismissed in regard to their health and underlying medical history. https//bit.ly/2X7Klmd.Humidified high-flow therapy (HFT) is a noninvasive respiratory therapy, typically delivered through a nasal cannula interface, which delivers a stable fraction of inspired oxygen (FIO2 ) at flow rates of up to 60 L·min-1. It is well-tolerated, simple to set up and ideally applied at 37°C to permit optimal humidification of inspired gas. Flow rate and FIO2 should be selected based on patients' inspiratory effort and severity of hypoxaemia. HFT yields beneficial physiological effects, including improved mucociliary clearance, enhanced dead space washout and optimisation of pulmonary mechanics. Robust evidence supports its application in the critical care setting (treatment of acute hypoxaemic respiratory failure and prevention of post-extubation respiratory failure) and emerging data supports HFT use during bronchoscopy, intubation and breaks from noninvasive ventilation or continuous positive airway pressure. There are limited data on HFT use in patients with hypercapnic respiratory failure, as an adjunct to cuss application of HFT in COVID-19 and aerosolisation of respiratory droplets.ILA/ILD extension and subpleural ILA localisation are risk factors for disease progression in RA subjects. A semiquantitative method to assess ILA/ILD extent and to measure the fibrotic burden is feasible to accurately determine ILA progression. https//bit.ly/3mmMJk2.Black pleural effusion is a rare entity and may be a diagnostic dilemma. This interactive case discusses the various steps involved to reach the diagnosis. https//bit.ly/3dFJPTS.Extrapulmonary tuberculosis (EPT) can affect all organs. Its diagnosis is often challenging, especially when the lung is not involved. Some EPT locations, such as when the central nervous system is involved, are a medical emergency, and some have implications for treatment options and length. This review describes clinical features of EPT, diagnostic tests and treatment regimens.Platypnoea-orthodeoxia syndrome refers to shortness of breath and oxygen desaturation in an upright position. Ventilation/perfusion mismatch is a rare cause of the same. Herein, we report a case of bilateral lower lobe tuberculosis, causing platypnoea and orthodeoxia. https//bit.ly/3jhJEQ1.Pneumonitis due to primary toxoplasmosis in an immunocompetent subject is rare. Here, the mononucleosis-like syndrome, associated with serological evidence of T. gondii infection and positive PCR for T. gondii in BAL, allowed us to establish the diagnosis.
