  • Incineration-Generated Polyethylene Micro-Nanoplastics Increase Triglyceride Lipolysis and Absorption in an In Vitro Small Intestinal Epithelium Model Tue, 16 Aug 2022 06:00:00 -0400
    Despite mounting evidence of micro-nanoplastics (MNPs) in food and drinking water, little is known of the potential health risks of ingested MNPs, and nothing is known of their potential impact on nutrient digestion and absorption. We assessed the effects of environmentally relevant secondary MNPs generated by incineration of polyethylene (PE-I), on digestion and absorption of fat in a high fat food model using a 3-phase in vitro simulated digestion coupled with a tri-culture small intestinal...
  • Impaired activation of transposable elements in SARS-CoV-2 infection Tue, 16 Aug 2022 06:00:00 -0400
    Emerging evidence shows that transposable elements (TEs) are induced in response to viral infections. This TE induction is suggested to trigger a robust and durable interferon response, providing a host defense mechanism. Here, we analyze TE expression changes in response to SARS-CoV-2 infection in different human cellular models. Unlike other viruses, SARS-CoV-2 infection does not lead to global upregulation of TEs in primary cells. We report a correlation between TEs activation and induction...
  • COVID-19 and inflammatory bowel disease crosstalk: from emerging association to clinical proposal Tue, 16 Aug 2022 06:00:00 -0400
    Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection can cause Corona Virus Disease 2019 (COVID-19), an acute respiratory inflammation that has emerged worldwide since December 2019, and it quickly became a global epidemic. Inflammatory bowel disease (IBD) is a group of chronic nonspecific intestinal inflammatory diseases whose etiology has not been elucidated. The two have many overlapping symptoms in clinical presentation, such as abdominal pain, diarrhea, pneumonia, etc....
  • New-onset Parkinsonism as a Covid-19 infection sequela: A systematic review and meta-analysis Tue, 16 Aug 2022 06:00:00 -0400
    CONCLUSION: Despite presumed "recovery" from COVID-19, patients still face a wide range of neurological complications. One of these complications presenting as Parkinsonism requires health care professionals to be on the lookout for the long-term effects of COVID-19. Hence, our study provides information on the possible likely hood of a link between COVID-19 and the development of Parkinsonism as post-COVID neurological sequelae.
  • Musculoskeletal symptoms in patients with Long COVID: A cross-sectional study on Iranian patients Tue, 16 Aug 2022 06:00:00 -0400
    CONCLUSION: This study indicated a high prevalence of persistent musculoskeletal symptoms among patients who recovered from COVID-19. Modifiable factors, such as BMI, can be targeted to reduce the prevalence of musculoskeletal symptoms in COVID-19 survivors and reduce its burden.
  • Comparative Evaluation of Solubility of Gutta-Percha in Three Different Solvents: A Cone-Beam Computed Tomography (CBCT) Study Tue, 16 Aug 2022 06:00:00 -0400
    Background Gutta-percha is the most frequently used filling material for root canal obturation. This thermoplastic material fulfills the primary requisites for root canal filling, one of which is easily removable material in cases of endodontic retreatment. The most commonly used solvents were chloroform, xylene, and orange oil due to their effectiveness in dissolving and removing maximum gutta-percha in a minimum time. Aims The aim is to evaluate and compare the solubility of gutta-percha in...
  • Effectiveness of Commonly Used Contact Lens Disinfectants Against SARS-CoV-2 Tue, 16 Aug 2022 06:00:00 -0400
    CONCLUSIONS: Disinfectant solutions effectively disinfect CLs from SARS-CoV-2 if manufacturer's instructions are followed. The rub-and-rinse regimen is mainly responsible for disinfection. The viability PCR may be useful to indicate potential infectiousness.
  • Realization of a Model-Free Pathway for Quantum Dot-Protein Interaction Beyond Classical Protein Corona or Protein Complex Mon, 15 Aug 2022 06:00:00 -0400
    Although in recent times nanoparticles (NPs) are being used in various biological applications, their mechanism of binding interactions still remains hazy. Usually, the binding mechanism is perceived to be mediated through either the protein corona (PC) or protein complex (PCx). Herein, we report that the nanoparticle (NP)-protein interaction can also proceed via a different pathway without forming the commonly observed PC or PCx. In the present study, the NP-protein interaction between...
  • FeSO4·7H2O optimisation of earthed atomising corona discharge (Fe-EACD) a process for the pharmaceutical wastewater treatment Mon, 15 Aug 2022 06:00:00 -0400
    Pharmaceutical residues can cause serious water pollution problems, harm human health and destroy the ecological balance. FeSO(4)·7H(2)O optimisation of the earthed atomising corona discharge (Fe-EACD) process was used to dispose of pharmaceutical wastewater in this research. Experiments were analyzed by VI characteristic curves to optimise the electrode distance (20-50 mm) and wire electrode diameter (0.3-0.5 mm). The effects of discharging voltage (7-12 kV), time (0-54 min) and FeSO(4) dosage...
  • Selective detection of tartaric acid using amino acid interlinked silver nanoparticles as a colorimetric probe Mon, 15 Aug 2022 06:00:00 -0400
    A variety of biomolecules with different functional groups play critical roles in almost all the processes occurring in living cells. Interaction of metallic nanoparticles (NPs) with various biomolecules generates a layer of molecules on their surface, and this biomolecular rich layer formed on the NP surface is described as a "biomolecular corona". The physicochemical properties of the NPs, including size, adsorption affinity, and charge on the particles' surfaces are the major factors...
