Film Change

Cinema provides ‘privileged access’ ( Zubrycki 2011 ) into trans lives, recording and revealing private life experiences and moments that might never be seen, nor heard and after the time had passed, only present in memory and body for the individuals involved. Film, a temporal medium, creates theoretical issues, both in the presentation and representation of the trans body and for audiences in viewing the images. Specific narrative, stylistic and editing techniques including temporal disjunctions, may also give audiences a distorted view of trans bodily narratives that encompass a lifetime. Twenty first century cinema is simultaneously creating and erasing the somatechnical potentialities of trans. This article will explore temporal techniques in relation to recent trans cinema, comparing how three different filmmakers handle trans narratives. Drawing upon recent films including the Trans New Wave ( Ford 2014 , 2016a , 2016b ), such as the experimental animated autoethnographic short film Change Over Time (Ewan Duarte, United States, 2013), in tandem with the feature film 52 Tuesdays (Sophia Hyde, Australia, 2013), I will analyse the films as texts which show how filmmakers utilise temporality as a narrative and stylistic technique in cinematic trans narratives. These are texts where cinematic technologies converge with trans embodiment in ways that are constitutive of participants and audiences' understanding of trans lives. This analysis will be contrasted with the use of temporal displacement as a cinematic trope of negative affect, disembodiment and societal disjunction in the feature film Predestination (The Spierig Brothers, Australia, 2014), providing a further basis for scholarly critique of cinematic somatechnics in relation to the trans body.

Introduction. The profession of “machine operator in metalworking”, one of the most common professions in various industries, characterized by a large volume of abrasive operations, accompanied by dust formation, which creates a potential for the occurrence of diseases of the visual organ.The aim of the study is to provide a hygienic assessment of working conditions and occupational risk of visual organ pathology in metalworking machine operators.Materials and methods. Observation groups — machine operators for metalworking of two training groups (experience up to 5 years, experience of 6–20 years). Two comparison groups (administrative and technical personnel of the enterprise) are formed according to the same age-experience principle.Results. The working conditions of machine operators were classified as class 3.2. taking into account the severity and intensity of the work process and the noise level (80 dBA) in the workplace. Nitrogen oxide, carbon monoxide, and manganese were registered in the air of the working area in concentrations below the permissible concentration (PC), and the aerosol dihydroxide was registered above the PC in 25.8% of cases. In the main working groups, diseases of the anterior segment of the eye were more often registered, among which dry eye syndrome (DYS) prevailed (94.1%), chronic blepharoconjunctivitis (79.9%), persistent corneal opacification (21.7%). There was an increase in the prevalence of detected diseases with an increase in work experience (p≤0.05). In machine operators, the frequency of inhibition of lacrimal formation and decreased stability of the tear film was recorded significantly more often, with increasing work experience, the degree of violation of lacrimal formation and stability of the tear film increased. The chances of detecting pathology of the anterior segment of the eye in machine operators are 5.9 and 3.5 times higher than in the comparison group. There are different forces of connection, increasing with the increase of work experience in the profession, between the working conditions of machine operators and the occurrence of SHG (relatively strong), with chronic blepharoconjunctivitis and persistent corneal opacity (medium strength), which suggests the professional conditionality of this pathology.Conclusions. The results obtained suggest that the pathology of the anterior segment of the eye is professionally conditioned in metalworking machine operators and necessitate the introduction of preventive measures aimed at protecting the visual organ.

Dry eye syndrome is a common condition that results from reduced tear production or excessive tear evaporation or an abnormality in the production of mucus or lipids normally found in the tear layer or combination of these. If blinking is decreased or if the eyelids cannot be closed, they may dry out leading to dry eye. It is accompanied by increased osmolarity of the tear film and inflammation on the surface of the eye may occur of left untreated leading to pain, ulcers or scars on the cornea and loss of vision. Prevalence of dry eye range from 5% to 35% worldwide while in India it is 29.25%. Tear substitute are the only treatment modality with modern medicine, only providing symptomatic relief. Ayurveda describes similar condition called Sushkakshi Paka and this patient was treated with Tarpana and Nasya with Jeevantyadi Ghrita.

AbstractHerpes simplex keratitis (HSK), caused by herpes simplex virus type 1 (HSV-1) infection, is the commonest cause of infectious blindness in the developed world. Following infection the virus is initially suspended in the tear film, where it encounters a multi-pronged immune response comprising enzymes, complement, immunoglobulins and crucially, a range of anti-viral and pro-inflammatory cytokines. However, given that HSV-1 can overcome innate immune responses to establish lifelong latency throughout a susceptible individual’s lifetime, there is significant interest in understanding the mechanisms employed by HSV-1 to downregulate the anti-viral type I interferon (IFN) mediated immune responses. This study aimed to investigate the interactions between infected cell protein (ICP)0 and key elements of the IFN pathway to identify possible novel targets that contribute to viral immune evasion. Reporter gene assays demonstrated the ability of ICP0 to inhibit type I IFN activity downstream of pathogen recognition receptors (PRRs) which are known to be involved in host antiviral defences. Further experiments identified interferon regulatory factor (IRF)7, a driver of type I IFN, as a potential target for ICP0. These findings increase our understanding of the pathogenesis of HSK and suggest IRF7 as a potential therapeutic target.

Most studies about dry eye disease (DED) chose unilateral eye for investigation and drew conclusions based on monocular results, whereas most studies involving tear proteomics were based on the results of pooling tears from a group of DED patients. Patients with DED were consecutively enrolled for binocular clinical tests, tear biochemical markers of DED, and tear proteome. We found that bilateral eyes of DED patients may have similar but different ocular surface performance and tear proteome. Most ocular surface homeostatic markers and tear biomarkers were not significantly different in the bilateral eyes of DED subjects, and most clinical parameters and tear biomarkers were correlated significantly between bilateral eyes. However, discrepant binocular presentation in the markers of ocular surface homeostasis and the associations with tear proteins suggested that one eye’s performance cannot represent that of the other eye or both eyes. Therefore, in studies for elucidating tear film homeostasis of DED, we may lose some important messages hidden in the fellow eye if we collected clinical and proteomic data only from a unilateral eye. For mechanistic studies, it is recommended that researchers collect tear samples from the eye with more severe DED under sensitive criteria for identifying the more severe eye and evaluating the tear biochemical and proteomic markers with binocular concordance drawn in prior binocular studies.
