Pulmonary fibrosis (PF) is characterised by several grades of chronic inflammation and collagen deposition in the interalveolar space and is a hallmark of interstitial lung diseases (ILDs). Recently, infectious agents have emerged as driving causes for PF development; however, the role of viral/bacterial infections in the initiation and propagation of PF is still debated. In this context, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the current coronavirus disease 2019 (COVID-19) pandemic, has been associated with acute respiratory distress syndrome (ARDS) and PF development. Although the infection by SARS-CoV-2 can be eradicated in most cases, the development of fibrotic lesions cannot be precluded; furthermore, whether these lesions are stable or progressive fibrotic events is still unknown. Herein, an overview of the main molecular mechanisms driving the fibrotic process together with the currently approved and newly proposed therapeutic solutions was given. Then, the most recent data that emerged from post-COVID-19 patients was discussed, in order to compare PF and COVID-19-dependent PF, highlighting shared and specific mechanisms. BTK animal study A better understanding of PF aetiology is certainly needed, also to develop effective therapeutic strategies and COVID-19 pathology is offering one more chance to do it. Overall, the work reported here could help to define new approaches for therapeutic intervention in the diversity of the ILD spectrum.AB38b is a novel biphenyl diester derivative synthesized in our laboratory, and it has been shown to improve the pathology of nephropathy and encephalopathy in diabetic mice. Glioblastoma (GBM) is the most lethal brain tumor, without effective drugs to date. The present study aims at investigating the role of AB38b in GBM growth and revealing the underlying molecular mechanisms. We found that AB38b administration showed a dose- and time-dependent inhibition on cell proliferation in multiple immortalized and primary GBM cell lines, but it had no significant effects on human astrocyte cell line. More importantly, AB38b blocked cell cycle progression, induced early apoptosis, decreased the activity of AKT/mTOR pathway, and increased the generation of reactive oxygen species (ROS) in GBM cells. Interestingly, antioxidant treatments could reverse the AB38b-mediated abovementioned effects; overexpression of constitutively active AKT could partially rescue the suppressive effects of Ab38b on GBM cell proliferation. In addition, AB38b administration inhibited the tumor growth, decreased the activity of AKT/mTOR pathway, and prolonged the survival time in GBM animal models, without any adverse influences on the important organs. These findings suggest that AB38b exerts anti-glioma activity via elevating the ROS generation followed by inhibiting the activity of AKT/mTOR pathway.

The medicine quality is defined by its aptitude to meet certain requirements declared by the regulatory authorities. Among these, impurities control which constitutes the major fear of pharmaceutical manufacturers in efficiency and safety terms. Nowadays, in many developing countries, the presence of poor quality drugs is common, for this reason, an increased control should be instituted including impurities which represent a serious public health problem threatening the efficacy and the safety medicines, because of their nocuous repercussions on health. The objective of this study is to verify that impurities in certain APIs Ciprofloxacin, Metronidazole and Fluconazole actually collected on Algerian soil meet the impurity requirements.

An observational experimental study was carried out from 1

December 2013 to 31

December 2017, on impurities control in the APIs of Ciprofloxacin, Metronidazole and Fluconazole medicines registered in the Algerian Medicines Nomenclature and marketed in Algeria. All samppliance rate is high because of certain impurities detection exceeding the safety standards. So, we interpellate the health authorities to ensure the APIs impurities control before being put into the manufacturing process in order to prevent the potentially serious health problems that are difficult to control.

This study concluded that samples non-compliance rate is high because of certain impurities detection exceeding the safety standards. So, we interpellate the health authorities to ensure the APIs impurities control before being put into the manufacturing process in order to prevent the potentially serious health problems that are difficult to control.We examine the relationship between the rationing of health care resources and disparities in health care delivery and the specific implications for radiologic resource allocation frameworks such as the ACR Appropriateness Criteria. We explore what rationing is in this context and how it is manifested in radiology. We review how rationing has taken many forms and how rationing has influenced the development of disparities in access and outcomes within health care and specifically within the context of radiology. We describe how the relationship between rationing and health care delivery disparities manifested during the coronavirus disease 2019 pandemic and the corrective measures that were proposed to established rationing frameworks to facilitate more equitable pandemic-related resource distribution. We offer suggestions regarding how such solutions might be brought into radiologic resource allocation schemes to help mitigate disparities in radiologic care in the future.Academic success and how to achieve it takes diverse forms, depending on who's asked. We suggest that happiness, impact, and longevity can be achieved with professional effort and support that balances the toil and joys of one's chosen path.Retinotopic maps of many visual areas are thought to follow the fundamental principles described for the primary visual cortex (V1), where nearby points on the retina map to nearby points on the surface of V1, and orthogonal axes of the retinal surface are represented along orthogonal axes of the cortical surface. Here we demonstrate a striking departure from this mapping in the secondary visual area (V2) of the tree shrew best described as a sinusoidal transformation of the visual field. This sinusoidal topography is ideal for achieving uniform coverage in an elongated area like V2, as predicted by mathematical models designed for wiring minimization, and provides a novel explanation for periodic banded patterns of intra-cortical connections and functional response properties in V2 of tree shrews as well as several other species. Our findings suggest that cortical circuits flexibly implement solutions to sensory surface representation, with dramatic consequences for large-scale cortical organization.Thermoregulatory behavior is a basic motivated behavior for body temperature homeostasis. Despite its fundamental importance, a forebrain region or defined neural population required for this process has yet to be established. Here, we show that Vgat-expressing neurons in the lateral hypothalamus (LHVgat neurons) are required for diverse thermoregulatory behaviors. The population activity of LHVgat neurons is increased during thermoregulatory behavior and bidirectionally encodes thermal punishment and reward (P&R). Although this population also regulates feeding and caloric reward, inhibition of parabrachial inputs selectively impaired thermoregulatory behaviors and encoding of thermal stimulus by LHVgat neurons. Furthermore, two-photon calcium imaging revealed a subpopulation of LHVgat neurons bidirectionally encoding thermal P&R, which is engaged during thermoregulatory behavior, but is largely distinct from caloric reward-encoding LHVgat neurons. Our data establish LHVgat neurons as a required neural substrate for behavioral thermoregulation and point to the key role of the thermal P&R-encoding LHVgat subpopulation in thermoregulatory behavior.The brain exhibits distinct patterns of recurrent activity closely related to behavioral state. The neural mechanisms that underlie state-dependent activity in the awake animal are incompletely understood. Here, we demonstrate that two types of state-dependent activity, rapid arousal/movement-related signals and a 3-5 Hz alpha-like rhythm, in the primary visual cortex (V1) of mice strongly correlate with activity in the visual thalamus. Inactivation of V1 does not interrupt arousal/movement signals in most visual thalamic neurons, but it abolishes the 3-5 Hz oscillation. Silencing of the visual thalamus similarly eradicates the alpha-like rhythm and perturbs arousal/movement-related activation in V1. Intracellular recordings in thalamic neurons reveal the 3-5 Hz oscillation to be associated with rhythmic low-threshold Ca2+ spikes. Our results indicate that thalamocortical interactions through ionotropic signaling, together with cell-intrinsic properties of thalamocortical cells, play a crucial role in shaping state-dependent activity in V1 of the awake animal.

Although coronary artery bypass grafting using bilateral internal thoracic arteries (BITA) maximizes long-term survival, knowledge of the effect of different right ITA (RITA) inflow configurations on graft patency is limited. We have compared RITA occlusion among these configurations and identified its risk factors while adjusting for outflow coronary target location.

From 1/1972-1/2016, of 7,092 patients undergoing BITA grafting at a single center, 1,331 received 1 ITA to the left anterior descending coronary artery (LAD) and had ≥1 evaluable postoperative coronary angiograms 835 (63%) in-situ, 496 free-RITA grafts (311 [63%] originating from aorta, 98 [20%] left internal thoracic artery (LITA), 76 [15%] saphenous vein graft [SVG], 11 [2%] radial graft). RITA occlusion reported on 1,983 angiograms performed a median of 5.8 years later was estimated using nonlinear mixed-effects longitudinal modeling.

RITA patency was 90% at 1 year, 87% at 5 years, and 86% at 10 and 15 years. At 15 years, in-situ RITA patency was 91% and free RITA patency from aorta 91%, LITA 89%, and SVG 77%. After adjusting for coronary target location and degree of stenosis, occlusion was similar in free RITAs from aorta (P=.15), LITA (P=.4), SVG (P=.13), and in-situ RITAs. However, RITAs grafted to the LAD had fewer occlusions (P<.001), with patency similar to LITAs.

Among patients with BITA grafting requiring interval coronary angiography, long-term RITA patency was high and independent of its inflow configuration. Therefore, priority should be a RITA configuration optimizing its reach to important coronary targets, including the LAD.

Digoxin has been associated with reduced interstage mortality for patients with functional single ventricles with aortic hypoplasia/ductal-dependent systemic circulation. The NEONATE score can stratify patients by risk of death or transplant (DTx) based on clinical factors. We suspected a variable transplant-free survival benefit of digoxin in high- versus low-risk patients.

National Pediatric Cardiology Quality Improvement Collaborative patients discharged following stage 1 palliation with complete data were categorized as high- or low-risk based on a modified NEONATE score. The primary outcome of DTx was evaluated. A mixed-effect regression evaluated associations between digoxin prescription and risk factors.

1,199 patients were included; 399 (33%) were high-risk. Baseline demographics were similar between cohorts. Blalock-Taussig shunt (BTS)or Hybrid operation, post-operative extracorporeal membrane oxygenation, opiate prescription, and significant tricuspid regurgitation or arch obstruction were more common in high-risk patients.
