In the field of veterinary anatomy, most of the specimens used in practical sessions are perfused with fixatives. Thus, they can be used for a longer time, reducing the number of animals for educational purposes. Formalin is the most commonly used fixative, consisting of a 37% formaldehyde solution. However, formaldehyde is a powerful irritant of the eyes and airways and is considered carcinogenic, causing nasopharyngeal cancer in exposed workers and professionals. In the present study, we explored an alternative method to avoid the use of formaldehyde in specimens used for gross anatomy practical sessions...

PURPOSE: Birt-Hogg-Dubé Syndrome (BHDS) is a rare autosomal dominant condition that can predispose patients to numerous cutaneous fibrofolliculomas and other cutaneous lesions, pulmonary cysts with spontaneous pneumothorax, and multifocal renal tumors and cancer. The genetic mutations responsible for BHDS are related to tumor suppression and the mammalian target of rapamycin (mTOR) pathway. Previous reports of the ocular findings in BHDS include eyelid fibrofolliculomas, "flecked chorioretinopathy," and one report of choroidal melanoma...

Orbital exenteration is a disfiguring procedure performed for unresponsive orbital infections and control of recurrent benign tumours and malignancies arising from the eyelids (basal cell carcinoma, squamous cell carcinoma, conjunctival malignant melanoma), lachrymal glands (adenoid cystic carcinoma) or surrounding sinuses. In extremely rare cases the use of a prosthetic eye after enucleation can lead to anophthalmic socket tumours. We report the case of a 54-year-old man who had left eye enucleation due to recurring events of retinal detachment and who developed an invasive fast growing epidermoid carcinoma 30 years later...

Of skin cancers, 9% arise at the periocular level, constituting a significant threat due to the proximity to intracranial structures, such as the eyes, nerve endings and proximal tissues. Tumour recurrence can be frequent and represents a primary clinical challenge for the surgeon. To present a retrospective study on the treatment of eyelid tumours at a tertiary care centre in Italy over an eight-year period and, in particular, to underline the risk factors associated with tumour relapse. Among a cohort of 205 patients, a retrospective study was conducted on 142 basal cell carcinoma (BCC) patients with eyelid tumours treated with surgical excision...

The climate changes, which occurred during the last decades, put all living species in front of new challenges. Human biology is no exception to it, all tissues have to face new effects, with unpredictable consequences. Many cancers, mainly affecting the skin, but also many of the eye various structures diseases, have ultraviolet radiation as recognized causative agent. The aim of our work is to highlight the changes that can occur after exposure to ultraviolet radiations of soft tissues, including eye structures, by reviewing data from the scientific literature regarding the matter...

BACKGROUND: Mandibular hypoplasia, deafness, progeroid features, and lipodystrophy syndrome (MDPL) is an autosomal dominant systemic disorder characterized by prominent loss of subcutaneous fat, a characteristic facial appearance and metabolic abnormalities. This syndrome is caused by heterozygous de novo mutations in the POLD1 gene. To date, 19 patients with MDPL have been reported in the literature and among them 14 patients have been characterized at the molecular level. Twelve unrelated patients carried a recurrent in-frame deletion of a single codon (p...

The diagnosis and management of eyelid cancers are quite challenging. Eyelid tumours are relatively rare diverse group of diseases varied in their presentation and extent. Many benign tumours and inflammatory conditions quite frequently masquerade eyelid cancers. Eyelid cancers are not single entity but comprise a wide range of tumours with extremes of tumour biology from indolent to very aggressive histopathologic types. Compromise on aesthetics and eyelids' indispensable function of protecting the eyes during management, may lead to untoward cosmetic disfigurement and loss of vision...

Alpha B-crystallin (CRYAB, HSPB5) is a protein that was first discovered in the lens of the eye. It is a member of the small heat-shock protein family (sHsps). CRYAB functions primarily as a molecular chaperone to prevent the aggregation and degradation of damaged unfolded proteins due to cellular damage resulting from heat shock, radiation, oxidative stress, and other insults, thereby promoting cell survival and preventing apoptosis. In recent years, the role of CRYAB in tumorigenesis, tumor invasion, and metastasis has received increasing attention...

Background Malignant melanoma is the most common cancer of the eye in adults that originates either in the intra-ocular uveal tract or extra-ocular conjunctiva. Although the primary tumor can be treated successfully, no effective therapy for both metastatic conjunctival and uveal melanoma currently exits. Tumor-associated lymphangiogenesis and immune cell infiltration play a pivotal role in the development and therapeutic targeting of metastases. Project description Here, we provide an overview of current translational research on lymphangiogenesis and its therapeutic inhibition as well as modulation of immune cell infiltration by passive and active immunotherapy in melanoma of the eye...

S-1 is an anticancer agent that consists of tegafur, gimeracil, and oteracil potassium at a molar ratio of 1:0.4:1. S-1 is used to treat metastatic and resectable gastric cancer. However, the extensive use of S-1 in clinical practice results in watery eyes, a serious clinical problem, which worsens patients' quality of life. Although repeated instillation of artificial tears is recommended, therapy or prophylaxis against S-1-induced ocular toxicity has not been established. In the present study, we evaluated the alleviating effects of repeated artificial tear instillation on S-1-induced ocular toxicity in dogs...

Background. The pressure-induced axonal injury of the vulnerable ONH has led many researchers to view glaucoma from the perspective of the genetic basis of the angle of the ONH. However, genetic studies on POAG from this perspective are limited. Methods. Microarray dataset GSE45570 of the ONH of healthy individuals and POAG patients were downloaded from the Gene Expression Omnibus. After screening for the DEGs using the limma package, enrichment analysis was performed using DAVID. The DEG interaction network was constructed using cancer spider at BioProfiling...

Retinoblastoma (RB) is a rare type of tumor which occurs in the intraocular spaces of eye. Carboplatin (CRB) has been used for the treatment of RB along with focal therapy. In this study, we have demonstrated the preparation of EpCAM-conjugated mesoporous silica nanoparticles for the successful delivery of carboplatin (CRB) to the retinoblastoma cells. The particles size and morphology was nanosized and spherical and exhibited a controlled release kinetics. Cellular uptake studies reveal that enhanced internalization was observed for EpCMSN compared to that of CMSN...

With countless preclinical studies on block copolymer micelles (BCMs) successfully demonstrating the superiority of these advanced drug delivery formulations over conventional formulations, it remains somehow discouraging that only a few have reached clinical evaluation and practice. With a critical eye, this review aims to compare and summarize the preclinical and clinical data available on several BCM formulations and to identify their primary role in drug delivery as "carrier" or "solubilizer". This review focuses on polymeric micelles that have reached clinical evaluation and/or are being pursued commercially...

Lian Liu, Jia-Zhi Liao, Xing-Xing He, Pei-Yuan Li
Autophagy is an evolutionarily conserved lysosome-dependent catabolic process which degrades cell's components in order to recycle substrates to exert optimally and adapt to tough circumstances. It is a critical cellular homeostatic mechanism with stress resistance, immunity, antiaging, and pro-tumor or anti-tumor effects. Among these, the role of autophagy in cancer is the most eye-catching that is not immutable but dynamic and highly complex. Basal autophagy acts as a tumor suppressor by maintaining genomic stability in normal cells...

REVIEW
Manish P Shrestha, Joannie Ruel, Sasha Taleban
The increasing number of older patients (age ≥60 years) with inflammatory bowel disease (IBD) highlights the importance of healthcare maintenance in this vulnerable population. Older IBD patients are more susceptible and have higher rates of many disease- and treatment-related adverse effects. Compared to younger IBD patients, older patients are at increased risk for infection, malignancy, bone disease, eye disease, malnutrition and thrombotic complications. Preventive strategies in the elderly differ from those in younger adults and are imperative...

A system for stabilising and monitoring eye movements for linac-based stereotactic radiotherapy associated with the mobile eye, the Eye Tracker, was developed. Whilst the Eye Tracker design is based on a previously reported system, the purpose of this study was to confirm that the modified version can be used with clinically acceptable treatment margins. We report the estimates of the margin required to account for inter- and intra-fraction eye motion based on data from 12 consecutive patients treated with the Eye Tracker system in place...
