Quantitative real time PCR (RT-PCR) is widely used as the gold standard for clinical detection of SARS-CoV-2. However, due to the low viral load specimens and the limitations of RT-PCR, significant numbers of false negative reports are inevitable, which results in failure to timely diagnose, cut off transmission, and assess discharge criteria. To improve this situation, an optimized droplet digital PCR (ddPCR) was used for detection of SARS-CoV-2, which showed that the limit of detection...

Managing recovered COVID-19 patients with recurrent-positive SARS-CoV-2 RNA test results is challenging. We performed a population-based observational study to characterize the viral RNA level and serum antibody responses in recurrent-positive patients and evaluate their viral transmission risk. Of 479 recovered COVID-19 patients, 93 (19%) recurrent-positive patients were identified, characterized by younger age, with a median discharge-to-recurrent-positive length of 8 days. After readmission, recurrent-positive patients exhibited mild (28%) or absent (72%) symptoms, with no disease progression....

Following acute infection, individuals COVID-19 may still shed SARS-CoV-2 RNA. However, limited information is available regarding the active shedding period or whether infectious virus is also shed. Here, we monitored the clinical characteristics and virological features of 38 patients with COVID-19 (long-term carriers) who recovered from the acute disease, but still shed viral RNA for over 3 months. The median carrying history of the long-term carriers was 92 days after the first admission, and the...

The modulatory effect of tranilast on neuropathic pain in type-2 diabetes (T2DM) remains unclear. We monitored interleukin (IL)-1β, nuclear factor-κB (NF-κB) and tumour necrosis factor-α (TNF-α) levels during the progression of T2DM induced neuropathic pain in rats, and assessed the impact of tranilast treatment of increasing concentrations (0, 200 and 400 mg/kg/day via oral gavage in 1% NaHCO3 delivered as 100 mg/kg twice a day) on the levels of cytokine production, as well as on...

Palbociclib, a selective CDK4/6 kinase inhibitor, is approved in combination with endocrine therapies for the treatment of advanced estrogen receptor positive (ER+) breast cancer. In pre-clinical cancer models, CDK4/6 inhibitors act primarily as cytostatic agents. In two commonly studied ER+ breast cancer cell lines (MCF7 and T47D), CDK4/6 inhibition drives G1-phase arrest and the acquisition of a senescent-like phenotype, both of which are reversible upon palbociclib withdrawal (incomplete senescence). Here we identify an ER+ breast...

The intracellular pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium) exploits host macrophage as a crucial survival and replicative niche. To minimize host immune response stimulated by flagellin, the expression of flagellar genes is downregulated during S. Typhimurium growth within host macrophages. However, the underlying mechanisms are largely unknown. In this study, we show that STM14_1285 (named AsiR), a putative RpiR-family transcriptional regulator, which is downregulated within macrophages as previously reported and also confirmed here, positively...

Curcumin (Cur) is a flavonoid derived from Curcuma longa L. that has been shown to have a variety of biological activities, but some previous studies have described its non-negligible negative effects on female reproduction and embryo development. To further explore the toxic stress effect, this study investigated apoptosis and autophagy of healthy buffalo (Bubalus bubalis) derived granulosa cells (GCs) exposed to Cur and/or autophagy inhibitors. Results showed that Cur declined viability of GCs in a...

Adhesives with properties of low-temperature and water-resistance are important in manufacturing. In this work, dopamine hydrochloride (DA), containing catechol groups, was introduced into the polymer by covalent grafting to obtain water-resistant films. Films with low-temperature and water-resistance properties were obtained through layer-by-layer assembly of branched polyethyleneimine (bPEI) and chemically cross-linked hyaluronate (HA)-DA (denoted HA-D). The film surfaces were wetted with moisture generated from low-temperature pretreatment, and the resulting films, named as bPEI/HA-D multilayer films, could...

Hepatitis B virus (HBV) middle surface antigen (MHBs) mutation or deletion occurs in patients with chronic HBV infection. However, the functional role of MHBs in HBV infection is still an enigma. Here, we reported that 7.33% (11/150) isolates of CHB patients had MHBs start codon mutations compared with 0.00% (0/146) in acute hepatitis B (AHB) patients. Interestingly, MHBs loss accounted for 11.88% (126/1061) isolates from NCBI GenBank, compared with 0.09% (1/1061) and 0.00% (0/1061) for...

Users rely heavily on mobile phones as multi-purpose devices to support all kinds of tasks. This study conceptualises mobile phone deep structure use and aims at unveiling such behaviour. Towards this end, this study goes beyond the traditional technology usage theories based on rationality and instrumentality. It is replaced by a relationship-based theory, the attachment theory, to investigate how users’ attachment to mobile phones is formed and how such attachment influences mobile phone deep structure...

To investigate the functions of hexokinase 1 (HK1) in the formation of goose fatty liver, a total of 40 healthy 63-day-old male Landes geese were selected and randomly assigned to a control group and an overfeeding treatment. In addition, the overexpression or RNA interference assay of HK1, and transcriptome analysis after HK1 overexpression were performed in the goose primary hepatocytes. Data showed that the mRNA expression of hepatic HK1 was upregulated in overfed treatment compared...

Transition metal oxide was considered as an effective cathode additive to depress ‘shuttle effect’ in lithium-sulfur (Li-S) batteries via forming a strong polar chemical bond with polysulfides. Here, we firstly synthesized unique S@Ni/NiO/ZnSnO3 microcubes as composite cathodes for Li-S batteries, in which Ni/NiO films were deposited onto surface of as-prepared ZnSnO3 microcubes via a hydrothermal reaction and later calcinations process. The S@Ni/NiO/ZnSnO3 composite showed attractive electrochemical performances with a high initial discharge-specific capacity of 1070...

In the present study, we aimed to investigate the role of long non-coding RNA terminal differentiation-induced non-coding RNA (TINCR) in cisplatin (DDP) resistance of choroidal melanoma (CM) and the potential molecular mechanisms. CM and non-CM tissues were collected from 60 CM patients. DDP-resistant CM cells were obtained by selection with linearly increased DDP treatment. The expression levels of TINCR, microR-19b-3p (miR-19b-3p), and extracellular signal-regulated kinase 2 (ERK-2) were detected by quantitative real-time PCR. Cholecystokinin octapeptide...

Diabetic kidney disease (DKD) is a serious diabetes complication. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are novel anti-diabetes drugs that confer clinical renal protection. However, the molecular mechanisms involved remain unclear. Here, human proximal tubular epithelial cells (PTECs) were treated with normal glucose, high glucose, and anti-diabetes agents, including SGLT2i (dapagliflozin), metformin, and dipeptidyl peptidase-4 inhibitor (DPP-4i, vildagliptin) and microarray analysis was performed. Firstly, a total of 2,710 differentially expressed circular RNAs (circRNAs) were identified. Secondly,...

Organic contaminants of emerging concern (OCECs) originating from assorted sources have attracted increasing attention latterly as most of them are not under routine surveillance or effective regulation but possess persistent, bioaccumulative, and toxic potential. Massive terrestrial inputs and proximity to intense human activities have elevated OCEC contamination in many estuaries. The present review outlines the current knowledge on the environmental occurrence and fate, as well as bioavailability of nine classes of OCECs, i.e., per- and...
