Tumor Infiltrating Lymphocytes as an Independent Prognostic Factor in Undifferentiated Nasopharyngeal Carcinoma.

Background: Nasopharyngeal carcinoma (NPC) is a common type of cancer in Southeast Asia. This cancer usually spreads locally and to nearby lymph nodes. One unique feature of NPC is its many immune cells called tumor-infiltrating lymphocytes (TILs).

Neuropathy caused by pesticide exposure on farmers in Ngablak District, Magelang, Central Java, Indonesia: An electroneuromyography study.

Uncontrolled and unsafe use of pesticides can lead to acute and chronic toxicity in farmers, with neuropathy being one of the most common symptoms of chronic toxicity. However, the effects of this toxicity on farmers' electroneuromyography (ENMG) are still unclear. To address this, we conducted a cross-sectional study from July to October 2017 in Ngablak District, Magelang, Central Java, Indonesia.

Complete genome analyses of G12P[8] rotavirus strains from hospitalized children in Surabaya, Indonesia, 2017-2018.

Rotavirus A (RVA) is a major viral cause of acute gastroenteritis (AGE) worldwide. G12 RVA strains have emerged globally since 2007. There has been no report of the whole genome sequences of G12 RVAs in Indonesia.

NS5A-ISGylation via Lysine 26 Has a Critical Role for Efficient Propagation of Hepatitis C Virus Genotype 2a.

We previously reported that hepatitis C virus (HCV) NS5A (1b, Con1) protein accepts covalent ISG15 conjugation at specific lysine (Lys) residues (K44, K68, K166, K215 and K308), exhibiting proviral effects on HCV RNA replication. Here we investigated a role of NS5A-ISGylation via Lys residues in HCV propagation using HCV infectious clone. The alignment of amino acid sequences revealed that 5 Lys residues (K20, K26, K44, K139, and K166) of the 13 Lys residues within NS5A (genotype 2a, JFH1 strain) were conserved compared to those of HCV (genotype 1b, Con1 strain).

HERC5 E3 ligase mediates ISGylation of hepatitis B virus X protein to promote viral replication.

Ubiquitin and ubiquitin-like protein modification play important roles in modulating the functions of viral proteins in many viruses. Here we demonstrate that hepatitis B virus (HBV) X protein (HBx) is modified by ISG15, which is a type I IFN-inducible, ubiquitin-like protein; this modification is called ISGylation. Immunoblot analyses revealed that HBx proteins derived from four different HBV genotypes accepted ISGylation in cultured cells.

ISGylation of Hepatitis C Virus NS5A Protein Promotes Viral RNA Replication via Recruitment of Cyclophilin A.

Interferon-stimulated gene 15 (ISG15) is a ubiquitin-like protein that is covalently conjugated to many substrate proteins in order to modulate their functions; this conjugation is called ISGylation. Several groups reported that the ISGylation of hepatitis C virus (HCV) NS5A protein affects HCV replication. However, the ISG15 conjugation sites on NS5A are not well determined, and it is unclear whether the role of NS5A ISGylation in HCV replication is proviral or antiviral.

The D allele of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism is associated with worse functional outcome of ischaemic stroke.

Purpose: Insertion/deletion polymorphism in ACE gene (ACE I/D) is known to be associated with the occurrence of ischaemic stroke through its effect on pathogenesis of atherosclerosis and hypertension. This study was aimed to examine the association between this polymorphism with functional outcome of ischaemic stroke.

Method: This was a cross-sectional study.
