Red meat consumption and risk for dyslipidaemia and inflammation: A systematic review and meta-analysis.

Aim: The study (PROSPERO: CRD42021240905) aims to reveal the relationships among red meat, serum lipids and inflammatory biomarkers.

Methods And Results: PubMed, EMBASE and the Cochrane databases were explored through December 2021 to identify 574 studies about red meat and serum lipids markers including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), C-reactive protein (CRP) or hypersensitive-CRP (hs-CRP). Finally, 20 randomized controlled trials (RCTs) involving 1001 people were included, red meat and serum lipid markers and their relevant information was extracted.

Discovery of 4'-azido-2'-deoxy-2'-C-methyl cytidine and prodrugs thereof: a potent inhibitor of Hepatitis C virus replication.

4'-Azido-2'-deoxy-2'-methylcytidine (14) is a potent nucleoside inhibitor of the HCV NS5B RNA-dependent RNA polymerase, displaying an EC(50) value of 1.2 μM and showing moderate in vivo bioavailability in rat (F=14%). Here we describe the synthesis and biological evaluation of 4'-azido-2'-deoxy-2'-methylcytidine and prodrug derivatives thereof.

β-Branched acyclic nucleoside analogues as inhibitors of Plasmodium falciparum dUTPase.

We report a series of β-branched acyclic tritylated deoxyuridine analogues as inhibitors of Plasmodium falciparum deoxyuridine-5'-triphosphate nucleotidohydrolase (PfdUTPase), an enzyme involved in nucleotide metabolism that acts as first line of defence against uracil incorporation into DNA. Compounds were assayed against both PfdUTPase and intact parasites showing a correlation between enzyme inhibition and cellular assays. β-Branched acyclic uridine analogues described here showed equal or slightly better potency and selectivity compared with previously reported analogues.

Modified 5'-trityl nucleosides as inhibitors of Plasmodium falciparum dUTPase.

2'-Deoxyuridine triphosphate nucleotidohydrolase (dUTPase) is a potential drug target for the treatment of malaria. We previously reported the discovery of 5'-tritylated analogues of deoxyuridine as selective inhibitors of this Plasmodium falciparum enzyme. Herein we report further structure-activity studies; in particular, variations of the 5'-trityl group, the introduction of various substituents at the 3'-position of deoxyuridine, and modifications of the base.

The design, synthesis, and antiviral activity of monofluoro and difluoro analogues of 4'-azidocytidine against hepatitis C virus replication: the discovery of 4'-azido-2'-deoxy-2'-fluorocytidine and 4'-azido-2'-dideoxy-2',2'-difluorocytidine.

The discovery of 4'-azidocytidine (3) (R1479) (J. Biol. Chem.

The design, synthesis, and antiviral activity of 4'-azidocytidine analogues against hepatitis C virus replication: the discovery of 4'-azidoarabinocytidine.

4'-Azidocytidine 3 (R1479) has been previously discovered as a potent and selective inhibitor of HCV replication targeting the RNA-dependent RNA polymerase of hepatitis C virus, NS5B. Here we describe the synthesis and biological evaluation of several derivatives of 4'-azidocytidine by varying the substituents at the ribose 2' and 3'-positions. The most potent compound in this series is 4'-azidoarabinocytidine with an IC(50) of 0.

Nucleoside analogs as anti-HBV agents.

Chronic hepatitis B virus (HBV) infection affects about 400 million people worldwide. The development of nucleoside analogs that inhibit HBV polymerase provides an important approach for treating HBV infection. The approval of lamivudine, adefovir and entecavir represents a cornerstone of hepatitis B therapy.

[Effect of primary percutaneous coronary intervention on plasma B-type natriuretic peptide in patients with acute myocardial infarction].

Objective: To observe the effect of primary percutaneous coronary intervention (PCI) on plasma B-type natriuretc peptide (BNP) in patients with acute myocardial infarction (AMI).

Methods: Thirty-eight patients with AMI were divided into two groups for PCI (n=26) and conventional treatment (n=12). The plasma BNP levels were measured by fluorescence immunoassay (FIA) in these patients immediately, 24 h, 7 d, and 30 days after admission, and the infarct-related coronary arteries (IRA) were treated only with emergency interventional therapy in PCI group.

Validation of microdialysis sampling for oral availability studies by means of a new ganciclovir prodrug.

Microdialysis sampling was validated for oral availability studies using ganciclovir (9-(1, 3-dihydroxy-2-propoxymethyl) guanine) and a ganciclovir prodrug (9-(1-L-valyloxy-3-octadecanoyloxy-prop-2-oxymethyl) guanine). Three different techniques were used in the study; microdialysis, blood and urinesampling. The oral uptake (11+/-2%) and the urinary recovery (106+/-5%) were determined.
