Abstract

INTRODUCTION: Scarce reports have commented on hepatocellular carcinoma (HCC) behavior after direct-acting antivirals (DAAs).

AIM: To analyze differences in tumor behavior between patients with hepatitis C virus (HCV)-induced HCC and were either treated or not using DAAs.

PATIENTS AND METHODS: This case-control study includes patients with HCV-related HCC who received generic DAAs (group I) and all non-DAA treated patients with HCC who presented to our clinic during the same period (group II). Patient and tumor characteristics, treatment types and outcome were compared between the two groups.

RESULTS: Group I included 89 patients and group II included 207 patients. No significant difference was detected between groups regarding HCC number or size. Group I showed a more infiltrative HCC pattern, whereas group II had more circumscribed and delineated lesions. The incidence of portal vein thrombosis and significant lymphadenopathy was significantly higher in group I (P=0.03 and 0.03, respectively). Serum levels of α-fetoprotein were significantly higher in group I (P=0.02). These factors significantly affected the response to HCC management (P=0.03). Incidence of complete responses were 47.2 and 49.8% for groups I and II, respectively, whereas incomplete responses were 12.4 and 25.1%, respectively. Supportive treatment was applied to 40.4% in group I and 25.1% in group II.

CONCLUSION: HCC behavior was more aggressive in DAA-treated patients regarding portal vein thrombosis, malignant lymphadenopathy, and HCC imaging characteristics, which affected the chance of ablation and the treatment response.

Genetic polymorphism within the regulatory regions of tumor necrosis factor-alpha (TNF-α) and Lymphotoxin-alpha (LT-α) may be involved in the development of lymphoid malignancies. The aim of the current study was to investigate the effect of TNFα−308 and LTα+252 genetic polymorphism on susceptibility to non-Hodgkin lymphoma (NHL) in Egypt. Genotyping of the studied genes by restriction fragment length polymorphism polymerase chain reaction was conducted on 84 NHL and 100 healthy controls and revealed that TNFα−308 homotype (AA) was significantly higher in NHL patients and conferred sixfold increased risk of NHL (OR = 5.9, 95%CI = 2.3–16.1). Moreover, TNFα/LTα high-producer haplotypes were significantly higher in NHL patients and conferred increased risk of NHL (OR = 4.59, 95%CI = 2.19–9.42).

Abstract

Tau aggregation is believed to have a strong association with the level of cognitive deficits in Alzheimer's disease (AD). Thus, optical brain imaging of tau aggregates has recently gained substantial attention as a promising tool for the early diagnosis of AD. However, selective imaging of tau aggregates is a major challenge due to sharing similar β-sheet structures with homologous Aβ fibrils. Herein, four quinoline-based fluorescent probes (Q-tau) were judiciously designed using the donor-acceptor architecture for selective imaging of tau aggregates. In particular, probe Q-tau 4 exhibited a strong intramolecular charge transfer and favorable photophysical profile, such as a large Stokes' shift and fluorescence emission wavelength of 630 nm in the presence of tau aggregates. The probe also displayed a "turn-on" fluorescence behavior toward tau fibrils with a 3.5-fold selectivity Aβ fibrils. In addition, Q-tau 4 exhibited nanomolar binding affinity to tau aggregates ( = 16.6 nM), which was 1.4 times higher than that for Aβ fibrils. The mechanism of "turn-on" fluorescence was proposed to be an environment-sensitive molecular rotor-like response. Moreover, labeling of human AD brain sections demonstrated favorable colocalization of Q-tau 4 and the phosphorylated tau antibody, while comparable limited staining was observed with Aβ fibrils. Molecular docking was conducted to obtain insights into the tau-binding mode of the probe. Collectively, Q-tau 4 has successfully been used as a tau-specific fluorescent imaging agent with lower background interference.

Raga, et al., "Two closely linked tomato HKT coding genes are positional candidates for the major tomato QTL involved in Na+/K+ homeostasis", Plant, Cell and Environment, vol. 36, issue 6, pp. 1171 - 1191, 2013///. Abstract

The location of major quantitative trait loci (QTL) contributing to stem and leaf [Na+] and [K+] was previously reported in chromosome 7 using two connected populations of recombinant inbred lines (RILs) of tomato. HKT1;1 and HKT1;2, two tomato Na+-selective class I-HKT transporters, were found to be closely linked, where the maximum logarithm of odds (LOD) score for these QTLs located. When a chromosome 7 linkage map based on 278 single-nucleotide polymorphisms (SNPs) was used, the maximum LOD score position was only 35kb from HKT1;1 and HKT1;2. Their expression patterns and phenotypic effects were further investigated in two near-isogenic lines (NILs): 157-14 (double homozygote for the cheesmaniae alleles) and 157-17 (double homozygote for the lycopersicum alleles). The expression pattern for the HKT1;1 and HKT1;2 alleles was complex, possibly because of differences in their promoter sequences. High salinity had very little effect on root dry and fresh weight and consequently on the plant dry weight of NIL 157-14 in comparison with 157-17. A significant difference between NILs was also found for [K+] and the [Na+]/[K+] ratio in leaf and stem but not for [Na+] arising a disagreement with the corresponding RIL population. Their association with leaf [Na+] and salt tolerance in tomato is also discussed. © 2012 Blackwell Publishing Ltd.
