In mammalian cells, cohesin acetyltransferases Esco1 and Esco2 acetylate cohesin subunit Smc3 to establish chromosome cohesion, ensuring the accurate chromosome segregation. However, we have previously documented that both Esco1 and Esco2 have unique substrates and roles in mouse oocyte meiosis I to orchestrate the meiotic progression, but whether these functions are conserved among species is still not determined. Here, we used porcine oocytes as a model to illustrate that Esco1 and Esco2 exerted conserved functions...

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...

It is now clear that the intercellular transport on microtubules by dynein and kinesin-1 motors has an important role in the replication and spread of many viruses. Porcine epidemic diarrhea virus (PEDV) is an enveloped, single-stranded RNA virus of the Coronavirus family, which can infect swine of all ages and cause severe economic losses in the swine industry. Elucidating the molecular mechanisms of the intercellular transport of PEDV through microtubule, dynein and kinesin-1 will be...

Immune checkpoint inhibitors (ICIs) -induced adverse events (AEs) have been reported affecting almost all human organs. However, studies about ocular AEs are few. A meta-analysis was performed to evaluate the risks of ICI-related ophthalmic AEs compare to chemotherapy. Methods: Eligible studies were selected from phase II/III randomized controlled trials investigating ICIs. The data were analyzed by R software and Stata. Odds ratio of treatment-related AE (trAEs) and nonspecific ophthalmic trAEs (NS-trAEs) were lower for PD-1/PD-L1...

Two new cassane-type derivatives (1–2), together with three known compounds (3–5), were isolated from the seed kernels of Caesalpinia sinensis. Their structures were elucidated on the basis of interpretation of comprehensive spectroscopic data, including HRESIMS and 1D/2D NMR spectroscopy, and the absolute configuration were established by means of ECD calculation. Compound 2, possessing a 16-degradative cassane skeleton, was rarely encountered in cassane diterpenoids isolated from the genus Caesalpinia. All compounds were evaluated for their anti-inflammatory...

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...

Previous studies have explored associations between Tumour Necrosis factor-Alpha (TNF-a) polymorphisms and Schizophrenia. Their results were controversial. We conducted a meta-analysis to clarify the association between TNF-a − 308 G/A(rs1800629), −1031T/C(rs1799964), −863C/A(rs1800630) and −857 C/T (rs1799724) polymorphisms and Schizophrenia. All the studies that investigated the association between TNF-a polymorphisms and Schizophrenia published before 15 October 2020 were included in. The literature were comprehensively searched and identified in 2 English databases and 2 Chinese databases. The...

Resembling acute promyelocytic leukemia (APL) is a unique subtype of APL who sharing clinical, morphological, and immunophenotypic features with typical APL, but lacking evidence of PML-RARA fusion gene and usually insensitive to arsenic trioxide (ATO) and all-trans retinoic acid (ATRA). For years, RARA, RARB and RARG rearrangement were found in resembling APL continually. The confirmed partner genes of RARG rearrangement included CPSF6, NUP98, NPM1, PML, and HNRNPC. These patients were a group of resembling APL...
