Cadmium is a persistent ubiquitous environmental toxicant that elicits several biological defects on delicate body organs. Growing evidence suggests that cadmium (Cd) may perturb signaling pathways to induce oxidative pancreatitis. Thus, we explored whether hesperidin, a flavonone, could mitigate Cd-induced oxidative stress-mediated inflammation and pancreatitis in Wistar rats.

Forty (40) rats randomly assigned to 5 groups (n=8) were administered normal saline or hesperidin (Hsp) followed by Cd intoxication for 28days.

Cadmium accumulated in the pancreas of rats, and markedly decreased insulin, pancreatic superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities and glutathione (GSH) level. Cadmium considerably increased malondialdehyde (MDA), serum lipase and amylase activities. Cadmium induced pancreatic pro-inflammation via over-expression of inducible nitric oxide synthase (iNOS), nuclear factor-ĸB (NF-κB), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), along with histopathological alterations. Hesperidin prominently decreased serum amylase and lipase activities, and markedly increased insulin level, pancreatic antioxidant defense mechanism, whereas iNOS, NF-κB, IL-6 and TNF-α levels significantly decreased. Changes in histology confirmed our biochemical findings.

Our findings suggest that Cd induced pancreatitis via pro-inflammation and oxidative stress; Hsp, thus, protects against Cd-induced pancreatitis via attenuation of oxidative stress and proinflammatory responses in pancreas.

To describe the phenomenon of predatory publishing, its impact on the field of ophthalmology, and specific characteristics associated with predatory journals for authors to review prior to selecting a journal for submission of scientific work.

Descriptive editorial article.

Literature review of currently published literature regarding the topic.

Predatory publishing has had a significant impact on the quality of literature in the scientific world, on funding opportunities across countries and institutions, and on individual physician and scientist careers. AZD2281 There are a significant number of predatory journals in ophthalmology, but fewer than in other specialties.

We must raise awareness about the existence of predatory publishing within ophthalmology, and must individually act to limit contributing to its growth by critically appraising each publisher and journal prior to submitting our scientific work.

To evaluate the repeatability of curvature zone averages centered on the point of maximum curvature (Kmax) compared to that of the single-point Kmax.

Comparative reliability analysis.

Setting American University of Beirut Medical Center, Beirut, Lebanon.

Sixty-five eyes of 65 adult keratoconus patients. Patients with other ocular disease, history of ocular surgery or trauma, and contact lens wear within 2weeks of image acquisition were excluded.

Eyes were evaluated with 3 consecutive scans using the Galilei dual Scheimpflug-Placido system.

Repeatability of axial and instantaneous Kmax single points, and zone averages with radii of 0.1-2.0mm, centered on them. Repeatability was assessed by within-subject standard deviations, repeatability limits (r), and intraclass correlation coefficients.

Axial curvature zone averaging yielded clinically acceptable repeatability only in eyes with Kmax ≤50 diopters (D), for radii of 1.5mm and 2.0mm (r= 0.87 D and r= 0.76, respectively, vs r= 0.91 for the single-point axial Kmax). Compared to instantaneous Kmax, clinically acceptable repeatability was achieved with instantaneous zone averages of at least 1.5mm radius in eyes with Kmax ≤50 D (r= 0.99 D and r= 0.70 D, respectively) and 2.0mm radius in eyes with Kmax >50 D (r= 2.28 D and r= 0.87 D, respectively). For all eyes, the repeatability limit of the location of Kmax was 0.82mm and 0.80mm for axial and instantaneous curvature, respectively.

Instantaneous curvature zone averages centered on Kmax yielded a greater improvement in repeatability than axial zone averages and reached clinical adequacy with radii of at least 1.5mm, for eyes with Kmax ≤50 D, and with a 2.0mm radius for eyes with Kmax >50 D.

To highlight the increasing importance of gene fusions in the diagnosis, prognosis, and therapy of ocular adnexal tumors.

Perspective.

A focused review of gene fusions, their pathogenic mechanism, and gene fusion detection methods in lacrimal gland and primary orbital and ocular adnexal soft tissue tumors; reappraisal of diagnostic, prognostic, and therapeutic approach to ocular adnexal tumors in light of emerging molecular genetic data.

The widespread implementation of fluorescence insitu hybridization and next-generation sequencing methods in pathology practice has led to identification of recurrent gene rearrangements and fusions in a variety of tumors. As a result, molecular genetic methods have become the gold standard for diagnosis of tumors with overlapping histology and immunophenotype, such as small round blue cell tumors. Identification of canonic gene fusions has led to development of sensitive and specific immunohistochemical markers, such as STAT6 in solitary fibrous tumor. In addition to diagnostic accuracy, gene fusions have prognostic implications, such as unfavorable prognosis of PAX3-FOXO1 fusion in alveolar rhabdomyosarcoma. Finally, recognition of gene fusions as a driving mechanism in neoplasia has led to development of U.S. Food and Drug Administration-approved targeted therapies, such as TRK inhibitors for NTRK fusion-positive cancers.

The discovery of recurrent gene fusions in various tumors, including those involving ocular adnexa, has led to a deeper insight into the molecular mechanisms of these neoplasms, revolutionizing our approach to their diagnosis, prognostication, and therapy.
