56-1.06), which coincided with less traveling, more resting, and higher canopy use-though interannual variation was observed.

Herein, we describe behavioral and dietary patterns that are concordant with a time minimizing behavioral strategy. Black-and-white ruffed lemur diets comprised lower taxonomic diversity, fewer fruits, and more leaves during fruit-lean months. Further, shifts toward less travel, more resting, and greater use of higher canopy levels during this time were most likely for thermoregulatory benefits.

The ATP receptor P2Y

, which couples to G

and G

proteins, senses cell stress and promotes cytoprotective responses. P2Y

receptors are upregulated during differentiation of M2 macrophages. However, it is unclear whether and how P2Y

receptors contribute to the anti-inflammatory properties of M2 macrophages.

Transcriptome and secretome profiling of ectopic P2Y

receptors was used to analyse their signalling and function. Findings were validated in human monocyte-derived M2 macrophages. The suramin analogue NF340 and P2Y

receptor-knockout cells confirmed that agonist-mediated responses were specific to P2Y

receptor stimulation.

Temporal transcriptome profiling of P2Y

receptor stimulation showed a strong and tightly controlled response of IL-1 receptors, including activation of the IL-1 receptor target genes, IL6 and IL8. Secretome profiling confirmed the presence of IL-6 and IL-8 proteins and additionally identified soluble tumour necrosis factor receptor 1 and 2 (sTNFR1 and sTNFR2) as targets of P2Y

receptor activation. Raised levels of intracellular cAMP in M2 macrophages, after inhibition of phosphodiesterases (PDE), especially PDE4, strongly increased P2Y

receptor-induced release of sTNFR2 through ectodomain shedding mediated by TNF-α converting enzyme (TACE/ADAM17). Both IL-1α and IL-1ß synergistically enhanced P2Y

receptor- induced IL-6 and IL-8 secretion and release of sTNFR2. During lipopolysaccharide-induced activation of TLR4, which shares the downstream signalling pathway with IL-1 receptors, P2Y

receptors specifically prevented secretion of TNF-α.

Targeting P2Y

receptors activates IL-1 receptor signalling to promote sTNFR2 release and suppress TLR4 signalling to prevent TNF-α secretion, thus facilitating resolution of inflammation.

Targeting P2Y11 receptors activates IL-1 receptor signalling to promote sTNFR2 release and suppress TLR4 signalling to prevent TNF-α secretion, thus facilitating resolution of inflammation.Several descriptive studies have reported that higher neutrophil count (NC) may be correlated with poor prognosis in patients with confirmed COVID-19 infection. However, the findings from these studies are limited by methodology and data analysis. This study is a cohort study. We nonselectively and consecutively collected a total of 663 participants in a Chinese hospital from January 7 to February 28. Standardized and two-piecewise Cox regression model were employed to evaluate the association between baseline neutrophil count (bNC), neutrophil count change rate (NCR), and death. bNC had a U-shaped association with death. In the range of 0.1 to ≤1.49 × 109 /L (hazard ratio [HR] = 0.19, 95% confidence interval [CI] = 0.05-0.66) and >3.55 × 109 /L of bNC (HR = 2.82, 95% CI = 1.19-6.67), the trends on bNC with mortality were opposite. By recursive algorithm, the bNC at which the risk of the death was lower in the range of >1.49 to ≤3.55 × 109 /L (HR = 13.64, 95% CI = 0.25-74.71). In addition, we find that NCRs (NCR1 and NCR2) are not associated with COVID-19-related deaths. Compared with NCR, bNC has the potential to be used for early risk stratification in patients with COVID-19 infection. The relationship between bNC and mortality was U-shaped. The safe range of bNC was 1.64-4.0 × 109 /L. Identifying the correlation may be helpful for early risk stratification and medical decision-making.RNA exosome is a highly conserved ribonuclease complex essential for RNA processing and degradation. Bi-allelic variants in exosome subunits EXOSC3, EXOSC8 and EXOSC9 have been reported to cause pontocerebellar hypoplasia type 1B, type 1C and type 1D, respectively, while those in EXOSC2 cause short stature, hearing loss, retinitis pigmentosa and distinctive facies. We ascertained an 8-months-old male with developmental delay, microcephaly, subtle dysmorphism and hypotonia. Pontocerebellar hypoplasia and delayed myelination were noted on neuroimaging. A similarly affected elder sibling succumbed at the age of 4-years 6-months. Chromosomal microarray returned normal results. Exome sequencing revealed a homozygous missense variant, c.104C > T p.(Ser35Leu) in EXOSC1 (NM_016046.5) as the possible candidate. In silico mutagenesis revealed loss of a polar contact with neighboring Leu37 residue. Quantitative real-time PCR indicated no appreciable differences in EXOSC1 transcript levels. Immunoblotting and blue native PAGE revealed reduction in the EXOSC1 protein levels and EXO9 complex in the proband, respectively. We herein report an individual with the bi-allelic variant c.104C>T p.(Ser35Leu) in EXOSC1 and clinical features of pontocerebellar hypoplasia type 1. Immunoblotting and blue native PAGE provide evidence for the pathogenicity of the variant. Thus, we propose EXOSC1 as a novel candidate gene for pontocerebellar hypoplasia.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has proven to be extremely contagious and has spread rapidly all over the world. A key aspect in limiting the virus diffusion is to ensure early and accurate diagnosis. Serological assays could be an alternative in increasing testing capabilities, particularly when used as part of an algorithmic approach combined with molecular analysis. The aim of this study was to evaluate the diagnostic accuracy of a second generation chemiluminescent automated immunoassay able to detect anti-SARS-CoV-2 immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies. Data are carried out on healthy subjects and other infectious diseases pre-pandemic sera, as controls, and on two different coronavirus disease 2019 hospitalized patient groups (early and late infection time). Data obtained have been analyzed in terms of precision, linearity, sensitivity and specificity. Specificities are 100% for anti-SARS-CoV-2 IgG and 98% for anti-SARS-CoV-2 IgM, in all patient groups.
