8 fold in the GSTT1 null variant and 4.3 fold in the GSTP1 Ile/Val+Val/Val variant. The genetic combination (LOX GA+AA/GSTT1 active, LOX GG/GSTT1 null, LOX GA+AA/GSTT1 null, LOX GA+AA/GSTP1 Ile/Ile, LOX GG/GSTP1 Ile/Val+Val/Val and LOX GA+AA/GSTP1 Ile/Val+Val/Val) led to a higher lung cancer risk, compared to the reference group. The LOX GA/AA, GSTM1 null, GSTT1 null and GSTP1 Ile/Val, Val/Val genotypes contributed to increased lung cancer susceptibility. To the best of our knowledge, this is the first study of LOX genotyping in the Egyptian population. The combination of genotypes increased the risk of cancer, indicating the importance of gene-gene interaction and giving a targeted preventive approach.Neuronal senescence, triggered by telomere shortening, oncogene activation, DNA damage, or oxidative stress, has been associated with neurodegenerative diseases' pathogenesis. Therefore, preventing neuronal senescence could be a novel treatment strategy for neurodegenerative diseases. Lithium (Li), the first-line treatment against bipolar disorder, has been shown to have neuroprotective effects in clinical, pre-clinical, and in vitro studies. Li can protect cells from senescence, and its effect on neuronal senescence was investigated in our study. Furthermore, we also investigated the effects of Li on the senescence-associated miR-34a/Sirt1/p53 pathway. In this study, hydrogen peroxide was used as an inducer for the "stress-induced premature senescence" model. In the senescence model, we have assessed Li's effects on senescence by analyzing β-galactosidase activity, Sudan Black B, and senescence-associated heterochromatin foci (SAHF) stainings, and on cell cycle arrest by BrdU staining.

Finally, the effects of Li on senescence-associated miR-34a levels were measured by quantitative PCR. We show via Sudan Black B staining, β-Gal activity assay, and by detecting SAHF, Li protects against senescence in neuronal cells. Then, Li's effect on signaling has also been determined on pathways involved in senescence and cell cycle arrest. Moreover, we have observed that Li has a modulatory effect on miR-34a expression. Therefore, we posit that Li suppresses senescence in neuronal cells and that this effect is mediated through miR-34a/Sirt1/p53 axis.<br /><br /> Currently, no classification system using magnification endoscopy for the diagnosis of superficial Barrett's esophagus (BE)-related neoplasia has been widely accepted. This nationwide multicenter study aimed to validate the diagnostic accuracy and reproducibility of the magnification endoscopy classification system, including the diagnostic flowchart developed by the Japan Esophageal Society-Barrett's esophagus working group (JES-BE) for superficial Barrett's esophagus-related neoplasms.<br /><br /> The JES-BE acquired high-definition magnification narrow-band imaging (HM-NBI) images of non-dysplastic and dysplastic BE from 10 domestic institutions. A total of 186 high-quality HM-NBI images were selected. Thirty images were used for the training phase and 156 for the validation (test) phase. We invited five non-experts and five expert reviewers. In the training phase, the reviewers discussed how to correctly predict the histology based on the JES-BE criteria. In the validation phase, they evaluated whether the criteria accurately predicted the histology results according to the diagnostic flowchart. The validation phase was performed immediately after the training phase and at 6weeks thereafter.<br /><br /> The sensitivity and specificity for all reviewers were 87% and 97%, respectively. Overall accuracy, positive predictive value, and negative predictive value were 91%, 98%, and 83%, respectively. The overall strength of inter-observer and intra-observer agreements for dysplastic histology prediction was κ = 0.77 and κ = 0.83, respectively. No significant difference in diagnostic accuracy and reproducibility between experts and non-experts was found.<br /><br /> The JES-BE classification system, including the diagnostic flowchart for predicting dysplastic BE, is acceptable and reliable, regardless of the clinician's experience level.<br /><br />The JES-BE classification system, including the diagnostic flowchart for predicting dysplastic BE, is acceptable and reliable, regardless of the clinician's experience level.<br /><br /> In this retrospective case series multicentric study, we assessed the efficiency and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) among several types of advanced uncontrolled glaucoma cases. This study was intended to be a real-life study.<br /><br /> We treated 55 eyes with the Iridex Cyclo G6 device with the MP3 handpiece (IRIDEX Laser Systems) using a standardized protocol. Patients were followed up for a period of one year with an intention-to-treat protocol. Observation points are day 1, week 1, month 1, month 3, month 6, month 9 and year 1 after treatment. The primary outcome is a significant decrease in intra-ocular pressure (IOP) with a threshold of 20% reduction. The secondary outcomes are a reduction in the number of topical molecules needed to control glaucoma progression and the discontinuation of oral acetazolamide.<br /><br /> We observed a significant IOP reduction at every observation point with a mean preoperative IOP of 24.19mmHg (SEM 0.96) and mean IOP at final follow-up was 19.50mmHg (SEM 1.20). At least 50% of patients reached the significant threshold of 20% IOP reduction at every observation point except for month 6 follow-up. No significant reduction was achieved in the number of topical medications necessary to control glaucoma progression. Mean number of topical medications used at final follow-up is 3.00 (SEM 0.134). Mean number of topical molecules preoperatively was 3.08 (SEM 0.138). The discontinuation of oral acetazolamide was obtained with a statistically significant difference (p = 0.003).<br /><br /> Thanks to the design of this study, we add some proofs about the efficiency and the safety of MP-TSCPC for the treatment of uncontrolled advanced glaucoma cases in a real-life practice.<br /><br />Thanks to the design of this study, we add some proofs about the efficiency and the safety of MP-TSCPC for the treatment of uncontrolled advanced glaucoma cases in a real-life practice.
