The results revealed distance effects for comparisons to empty sets only when responding to target location, regardless of the response mode, indicating that spatial features should be primed in order to perceive an empty set as a numerical entity. These findings show that perceiving an empty set as nothing or as zero depends on the context in which it is presented.
  The Idiopathic Inflammatory Myositis (IIM) are heterogenous with distinct clinical phenotypes associated with specific myositis specific antibodies (MSA) and myositis associated antibodies (MAA).
 
  To evaluate the frequency, pattern and associations of MSA/MAA in a large Indian cohort of IIM.
 
  Adult and juvenile IIM (2017 ACR/EULAR criteria), were recruited in the MyoCite cohort between 2017and 2020 at a tertiary center in Northern India. Standardized clinical and laboratory variables were extracted from the database archive. Serum samples were evaluated for the presence of MSAs/MAAs by Line immunoassay and anti-nuclear antibodies (ANA) by Immunofluorescence assay (IFA). The prevalence and clinical associations of different MSA/MAAs were assessed.
 
  MSA and MAAs were tested in 250 IIM patients (214 adults, 36 children) of age [40 (30
  49), 13 (7.5-16) years] and disease duration [ 7 (3-17), 6 (2-17) months] comprising predominantly of Dermatomyositis (DM) followed by Overlap myositis (OM). MSAs/MAAs were fMyositis autoantibodies are seen in two-thirds IIMs and are associated with distinct clinical subsets. Jo-1 and non-Jo-1 ASS exhibit similar characteristics. The association of anti-TIF1 γ with malignancy was confirmed in adults. MSA/MAA were present in two-thirds of those with negative ANA and MSA were nearly always mutually exclusive.

  Colchicine has been used historically as an anti-inflammatory agent for a wide range of diseases. Little is known regarding the relationship between colchicine use and infectious disease outcomes. The objective of this study was to systematically examine infectious adverse events associated with colchicine usage and the clinical use of colchicine for infectious diseases.
 
  A systematic review was conducted in accordance with PRISMA methodology. PubMed, EMBASE, Scopus and Cochrane Library databases were searched (up to 12
  October, 2020) for interventional and observational studies that included colchicine usage associated with infectious adverse events or infectious disease outcomes.
 
  A total of 9,237 studies were initially identified and after exclusions, 36 articles comprising 21 interventional studies and 15 observational studies were included in this systematic review. There were 19 studies that reported infectious adverse events and 17 studies that examined the efficacy of colchicine in treating infet of COVID-19 but results from more clinical trials are needed. There is inconclusive evidence that suggests colchicine is associated with increased risk of infections, particularly pneumonia.
 There is a current lack of clinical evidence that colchicine has a role in treating or managing infectious diseases. Preliminary studies have demonstrated a possible role in the management of COVID-19 but results from more clinical trials are needed. There is inconclusive evidence that suggests colchicine is associated with increased risk of infections, particularly pneumonia.A series of iminopyridine complexes of platinum(II), bearing a flexible diethereal, aryl terminated residue, where the size of aryl group is varied from phenyl to 9-anthracenyl, was synthesized. The new complexes are soluble and stable in DMSO/H2O mixtures. Besides the metal center, aryl groups are available for further interactions with DNA, due to the good side chain flexibility. The new aryl functionalized iminopyridine dichlorido platinum(II) complexes show a significant antiproliferative activity on ovarian carcinoma cells and notably, complex 13 is able to overcome cisplatin resistance. The study of the interaction mode of 13 with DNA highlighted the ability to form a molecular complex characterized by a dual (intercalative and groove binding) geometry. The complex is also able to covalently add to DNA even though interstrand cross-links appear significantly hampered with respect to cisplatin. The interactions with the macromolecule are discussed in view of the observed cell effect.Swine influenza viruses not only constitute a potential economic problem for livestock, but also pose a substantial threat to human health. Mutation in the proteolytic cleavage site of hemagglutinin (HA) is recognized as an essential factor of tissue tropism and viral pathogenicity. However, the molecular properties of the cleavage site of Eurasian avian-like swine (EA) H1N2 virus remain largely unknown. In this study, we found a serine-leucine (Ser-Leu) substitution at the P2 position of the HA cleavage site (S328 L) in naturally occurring EA H1N2 virus. To study the effect of this substitution, we used reverse genetics to generate recombinant wild-type and mutant viruses containing a single amino acid mutation at the P2 position in A/swine/Guangdong/YJ28/2014 (YJ28) or A/swine/Guangdong/DG2/2015 (DG2) background. In vitro experiments showed that the Ser-Leu substitution at the P2 position attenuated the viral replication and HA cleavage efficiency. In vivo analyses revealed that, while all mice inoculated with r/DG2-S328 L or r/YJ28 viruses survived, the survival rates of r/DG2- and r/YJ28-L328S-inoculated animals were 20 % and 40 %, respectively. Furthermore, the Ser-Leu substitution at the P2 position attenuated the replication in nasal turbinate and lungs. In summary, this amino acid change may be useful to understand the molecular properties of the cleavage site and be valuable for vaccine development.A robust and comprehensive infection control plan in a senior living community is a must. Delirium manifestations of Covid-19 and or Urinary Tract Infections, may be confused or misdiagnosed with dementia symptoms in memory care residents. A robust incontinence care program is a key pillar of infection control to reduce symptoms causing hospitalization. Misdiagnosis, transfer infections, acute treatment dementia challenges, worsening incontinence are all risks of residents being hospitalized. A comprehensive incontinence assessment, plan, and education program are all paramount to seeing a reduction in hospitalizations and misdiagnosis of Covid-19 and other symptoms.
