Objective: Robotic surgical systems offer better workplace in order to relieve surgeons from prolonged physical efforts and improve their surgical outcomes. However, robotic surgery could produce musculoskeletal disorders due to the prolonged sitting position of the operator, the fixed position of the console viewer and the movements of the limbs. Until today, no one study has been reported concerning the association between robotics and musculoskeletal pain. The aim of this work was verify the prevalence of musculoskeletal disorders among Italian robotic surgeons. Material and methods: Between July 2011 and April 2012 a modified Standardized Nordic Questionnaire was delivered to thirty-nine Italian robotic centres. Twentytwo surgeons (56%) returned the questionnaires but only seventeen questionnaires (43.5%) were evaluable. Results: Seven surgeons (41.2%) reported musculoskeletal disorders, by since their first use of the robot which significantly persisted during the daily surgical activity (P < 0.001). Regarding the body parts affected, musculoskeletal disorders were mainly reported in the cervical spine (29.4%) and in the upper limbs (23.5%). Six surgeons (35.3%) defined the robotic console as less comfortable or neither comfortable/uncomfortable with a negative influence on their surgical procedures. Conclusions: In spite of some important limitations, our data showed musculoskeletal disorders due to posture discomfort with negative impact on daily surgical activity among robotic surgeons. These aspects could be due to the lack of ergonomic seat and to the fixed position of the console viewer which could have produced an inadequate spinal posture. The evaluation of these postural factors, in particular the development of an integrated and more ergonomic chair, could further improve the comfort feeling of the surgeon at the console and probably his surgical outcomes.

On the basis of a systematic analysis of the scientific literature, it was found that the increased sensitivity of a modern human being to the negative effects of the cold natural environment is due to its passage from the shrouds of East Africa with characteristic high ambient temperatures, primarily atmospheric air. At the same time, in comparative terms, the extinct Neanderthal, with his Eurasian apprehension in the conditions of glacial periods, was on the contrary sufficiently well adapted to the cold environment. The subsequent adaptation of a modern human type at the genetic level with the formation of the main races (Caucasoid, Negroid, Mongoloid) could not sufficiently compensate for its insufficient resistance to the cold environment. According to the results of the research, the main ways of solving the problem of the negative influence of the cold natural environment on the ecological health of athletes were determined: the rationing of the order of sporting activities of athletes depending on the degree of low-temperature environment, diagnosing the athletes' hypersensitivity of the respiratory tract to cold atmospheric air, degree of tension of the processes of thermoregulation of the body. The conclusions are drawn according to which the prevention of the negative impact of extreme conditions of the cold environment (primarily cold atmospheric air) on the ecological health of athletes should be systemic, integrated. The system of preventive measures should include an early diagnosis of the development of airway hyperresponsiveness of athletes to the effects of cold atmospheric air, as well as an assessment of the degree of tension of the body's thermoregulatory system to the effect of cold. In the system of preventing the negative impact of the cold environment on the body of athletes engaged in winter sports in the open space, it is necessary to include regulation (normalization) of the temperature regime of cold atmospheric air when determining the possibility of holding sporting events. If necessary (the presence of hypersensitivity of the airways to the action of cold atmospheric air), it is advisable to use special means of protecting the respiratory tract of athletes from the negative influence of cold atmospheric air.

AbstractUniversity students spend most of their time in a sitting position. Prolonged sitting on ill-fitted furniture and the resulting lousy posture is making students having different musculoskeletal disorders and is strictly related to students learning outcomes. This study aims to improve postural comfort of chairs placed inside the Science & Technology Library at the University of Salerno. A previous study about these library chairs showed that the lumbar area was the most suffering part while perceived (dis)comfort was dependent on time. Based on this, an ergonomic redesign and, consequently, manufacturing of the chair has been done. A perceived-comfort comparison between the library chair and the redesigned one has been performed. A statistical sample of 28 healthy students performed a 20-min experiment two times, alternatively on the library chair and the redesigned one. The 20-min experiment was divided into two 10-min tasks (“Reading & Writing” and “Laptop use”) to simulate a study day. The participants’ postures were acquired non-invasively using cameras and processed by Kinovea; questionnaires were used to rate the perceived subjective (dis)comfort. A procedure for improving an existing product through a comfort-driven redesign is proposed. Results showed the redesigned library chair lead on increasing postural comfort (particularly in the lumbar area) thanks to the new design and modifications.

Work Related Musculoskeletal Disorders

Introduction: Musculoskeletal disorder can result from extreme physical demands at work. It has risen, mainly due to high muscle demands and static postures and generates a significant economic burden to the companies. This short review aims to point out the statistics of the most affected body parts by work-related musculoskeletal disorders, assess absenteeism and presenteeism costs, and evaluate the effectiveness of the interventions. Methodology: According to the PRISMA Statement, the search was performed in 5 electronic databases (Scopus, Web of Science, Science Direct, Pubmed). Articles selection was made by the title and abstract analysis, especially those aiming to explain and validate the subject. If the abstract fulfils the objective, the articles were read, and studies were considered that met the defined eligibility criteria. Were chosen articles that realised measurements or considered interventions in healthy human beings, especially in the working population, dated from 2015 to 2020. Results and Discussion: The scrutinised articles were conclusive that the most affected part of the body are the upper limbs, the neck and the upper back. The statistics ofthe affected workers varied according to the country and analysed tasks, but they converge concerning the most affected body parts. It could be noted that women are more affected by musculoskeletal disorders than men, especially older women; the reason, however, is not clearly explained. Muscle injury can lead high economic burden, mostly due to absenteeism and presenteeism. It was noted that the expenditure due to presenteeism is higher comparing to absenteeism in both developed and emergent countries. Conclusions: Due to high costs, companies are deploying strategies to improve work conditions and aware the workers about health and safety. Interventions have shown to be effective in reducing the risk of injuries. Work-related musculoskeletal disorders canbe extremely damaging to the workers’ health and are costly to the companies. Support supervisor interventions effectively improve work conditions and reduce the risk of damaging outcomes, increasing workers’ health, work ability, and, consequently, productivity.

The connection between circadian rhythms and cancer is bilateral at the body and cellular level. Negative impact of tumor development on circadian rhythms represents one of its aspects. Materials and methods. 16 FVB/N and 16 FVB/N transgenic HER2/neu female mice were used in the experiment. 4 mice of each line were euthanized at ZT0 (light switch-on time), ZT6, ZT12 and ZT18. Bmal1, Clock and Cry1 gene expression was evaluated in the suprachiasmatic nucleus, liver, mammary tissue and tumors by real-time PCR. Content of BMAL1 and CLOCK proteins in mammary tissue and tumors was evaluated by immunohistochemistry. Results. Absence of clock genes expression and clock proteins content daily oscillations was observed in spontaneous mammary adenocarcinomas of HER2/neu transgenic mice. We also revealed decrease in peak values of clock genes expression in the suprachiasmatic nucleus, liver and mammary gland in tumor- bearing animals. Conclusions. The obtained data confirm the hypothesis about disruption of circadian rhythms in breast tumors and negative influence of tumors on the rhythms of the whole organism.

Melanoma is the most dangerous type of skin cancer in which mostly damaged unpaired DNA starts mutating abnormally and staged an unprecedented proliferation of epithelial skin to form a malignant tumor. In epidemics of skin, pigment-forming melanocytes of basal cells start depleting and form uneven black or brown moles. Melanoma can further spread all over the body parts and could become hard to detect. In USA Melanoma kills an estimated 10,130 people annually. This challenge can be succumbed by using the certain anti-cancer drug. In this study design, cyclophosphamide were used as a model drug. But it has own limitation like mild to moderate use may cause severe cytopenia, hemorrhagic cystitis, neutropenia, alopecia and GI disturbance. This is a promising challenge, which is caused due to the increasing in plasma drug concentration above therapeutic level and due to no rate limiting steps involved in formulation design. In this study, we tried to modify drug release up to threefold and extended the release of drug by preparing and designing niosome based topical gel. In the presence of Dichloromethane, Span60 and cholesterol, the initial niosomes were prepared using vacuum evaporator. The optimum percentage drug entrapment efficacy, zeta potential, particle size was found to be 72.16%, 6.19mV, 1.67µm.Prepared niosomes were further characterized using TEM analyzer. The optimum batch of niosomes was selected and incorporated into topical gel preparation. Cold inversion method and Poloxamer -188 and HPMC as core polymers, were used to prepare cyclophosphamide niosome based topical gel. The formula was designed using Design expert 7.0.0 software and Box-Behnken Design model was selected. Almost all the evaluation parameters were studied and reported. The MTT shows good % cell growth inhibition by prepared niosome based gel against of A375 cell line. The drug release was extended up to 20th hours. Further as per ICH Q1A (R2), guideline 6 month stability studies were performed. The results were satisfactory and indicating a good formulation approach design was achieved for Melanoma treatment.

This paper provides an analysis of how cultural notions of the body and kinship conveyed through Western medical technologies and practices in Assisted Reproductive Technologies (ART) bring together India's colonial history and its economic development through outsourcing, globalisation and instrumentalised notions of the reproductive body in transnational commercial surrogacy. Essential to this industry is the concept of the disembodied uterus that has arisen in scientific and medical practice, which allows for the logic of the ‘gestational carrier’ as a functional role in ART practices, and therefore in transnational medical fertility travel to India. Highlighting the instrumentalisation of the uterus as an alienable component of a body and subject – and therefore of women's bodies in surrogacy – helps elucidate some of the material and political stakes that accompany the growth of the fertility travel industry in India, where histories of privilege and difference converge. I conclude that the metaphors we use to structure our understanding of bodies and body parts impact how we imagine appropriate roles for people and their bodies in ways that are still deeply entangled with imperial histories of science, and these histories shape the contemporary disparities found in access to medical and legal protections among participants in transnational surrogacy arrangements.

To improve the workout efficiency and to provide the body movement suggestions to users in a “smart gym” environment, we propose to use a depth camera for capturing a user’s body parts and mount multiple inertial sensors on the body parts of a user to generate deadlift behavior models generated by a recurrent neural network structure. The contribution of this paper is trifold: 1) The multimodal sensing signals obtained from multiple devices are fused for generating the deadlift behavior classifiers, 2) the recurrent neural network structure can analyze the information from the synchronized skeletal and inertial sensing data, and 3) a Vaplab dataset is generated for evaluating the deadlift behaviors recognizing capability in the proposed method.

The Right

No one wants to be treated like an object, regarded as an item of property, or put up for sale. Yet many people frame personal autonomy in terms of self-ownership, representing themselves as property owners with the right to do as they wish with their bodies. Others do not use the language of property, but are similarly insistent on the rights of free individuals to decide for themselves whether to engage in commercial transactions for sex, reproduction, or organ sales. Drawing on analyses of rape, surrogacy, and markets in human organs, this book challenges notions of freedom based on ownership of our bodies and argues against the normalization of markets in bodily services and parts. The book explores the risks associated with metaphors of property and the reasons why the commodification of the body remains problematic. The book asks what is wrong with thinking of oneself as the owner of one's body? What is wrong with making our bodies available for rent or sale? What, if anything, is the difference between markets in sex, reproduction, or human body parts, and the other markets we commonly applaud? The book contends that body markets occupy the outer edges of a continuum that is, in some way, a feature of all labor markets. But it also emphasizes that we all have bodies, and considers the implications of this otherwise banal fact for equality. Bodies remind us of shared vulnerability, alerting us to the common experience of living as embodied beings in the same world. Examining the complex issue of body exceptionalism, the book demonstrates that treating the body as property makes human equality harder to comprehend.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.
