The gene matted (symbol ma) reported by Searle & Spearman (1957) causes the body-hair of affected mice to be brittle and inflexible; this results in longitudinal splitting and breaking due to friction against the cage and other objects. In the present paper the keratin abnormality of the hair is studied. The defect in matted hairs is compared with that of Naked (N/ +) mice (Grüneberg, 1952), and the hair-cycle in matted mice is described. Keratins probably vary widely in composition, but attempts to study their chemistry have been only partially successful (Bach, 1952; Neurath & Bailey, 1954; Rothman, 1954). All keratins are rich in cystine, and it has been shown that oxidation of thiol SH groups to cystine S—S occurs during keratinization (Giroud & Bulliard, 1930; Hardy, 1952). The strength of keratin depends largely upon cystine linkages (Goddard & Michaelis, 1934), hydrogen bonds (Alexander, 1951), and polar (salt) linkages (Speakman & Townsend, 1938); these unite the long polypeptide fibre molecules.

AbstractArthroscopic surgery is a technically challenging but common minimally invasive procedure with a long learning curve and a high incidence of iatrogenic damage. These damages can occur due to the lack of feedback and supplementary information regarding tissue-instrumentcontact during surgery. Deliberately performed interactions can be used however to obtain clinically relevant information, e.g. when a surgeon uses the tactile feedback to assess the condition of articular cartilage. Yet, the perception of such events is highly subjective. We propose a novel proximally attached sensing concept applied to arthroscopic surgery to allow an objective characterization and utilization of interactions. It is based on acoustic emissions which originate from tissue-instrument-contact, that propagate naturally via the instrument shaft and that can be obtained by a transducer setup outside of the body. The setup was tested on its ability to differentiate various conditions of articular cartilage. A femoral head with varying grades of osteoarthritic cartilage was tapped multiple times ex-vivo with a conventional Veress needle with a sound transducer attached at the outpatient end. A wavelet-based processing of the obtained signals and subsequent analysis of distribution of spectral energy showed the potential of tool-tissue-interactions to characterize different cartilage conditions. The proposed concept needs further evaluation with a dedicated design of the palpation tool and should be tested in realistic arthroscopic scenarios.

AbstractEarly diagnosis can be crucial to limit both the mortality and economic burden of cardiovascular diseases. Recent developments have focused on the continuous monitoring of cardiac activity for a prompt diagnosis. Nowadays, wearable devices are gaining broad interest for a continuous monitoring of the heart rate (HR). One of the most promising methods to estimate HR is the seismocardiography (SCG) which allows to record the thoracic vibrations with high non-invasiveness in out-of-laboratory settings. Despite significant progress on SCG, the current state-of-the-art lacks both information on standardized sensor positioning and optimization of wearables design. Here, we introduce a soft wearable system (SWS), whose novel design, based on a soft polymer matrix embedding an array of fiber Bragg gratings, provides a good adhesion to the body and enables the simultaneous recording of SCG signals from multiple measuring sites. The feasibility assessment on healthy volunteers revealed that the SWS is a suitable wearable solution for HR monitoring and its performance in HR estimation is strongly influenced by sensor positioning and improved by a multi-sensor configuration. These promising characteristics open the possibility of using the SWS in monitoring patients with cardiac pathologies in clinical (e.g., during cardiac magnetic resonance procedures) and everyday life settings.

LANGUAGE NOTE | Document text in Chinese; abstract also in English.通過引證《孝經》的傳統的重新注釋，本文指出中國生命倫理學界對“身體髮膚，受之父母，不敢毀傷”的理解有不足之處，既未注意到“毀傷”可作“刑傷”解，也未注意到“毀傷”即使作“損傷”解，以上說話也不排除親屬之間器官捐獻的可能性。此外，身體之完整在儒家倫理體系中並非最高道德原則，因為身與義的關係是需要考察具體的情境來做道德評判。在從新註釋儒家文本的前提下，筆者試圖證明，今天在中國大陸要推進器官捐獻事業，並不需要否定《孝經》中這一要求保持身體完整性的原則，因為儒家倫理體系與贊同器官捐獻並非不可化解的矛盾，問題的關鍵不是否定“不敢毀傷”，而是肯定器官捐獻的選擇合乎仁義，符合“立身行道”。論證捐獻器官挽救他人生命是一種值得讚美的高貴選擇可以將捐獻者及其家屬從所謂“不孝”的輿論壓力之下解脫出來。There is an organ shortage worldwide and particularly in China. Many researchers in the field of bioethics agree that Confucianism impedes the modern notion of organ donation due to its position on “filial piety” (xiao) in terms of “not damaging one’s body.” The Confucian concept of xiao demands that children obey their parents, serve them diligently, bury them respectfully and worship them afterward. It also proclaims that a person’s body, hair and skin are gifts from their parents that cannot be damaged.This essay intends to show that such an interpretation of the Confucian concept of xiao is misleading because it is based on a misreading of an important statement from the Xiaojing (Classic of Filial Piety). According to some exegeses, the idea of “damage” in the original text should be understood as “damage via criminal punishment” instead of a general kind of “damage.” The author contends that it is equally problematic for people to consider keeping one’s body intact as a supreme principle in Confucian moral teachings. Although filial piety is a key principle in Confucianism, it is not the primary factor holding back organ donation. Although traditional Confucian principles emphasize the “wholeness of the body,” they do not prevent many Confucian scholars from taking different views, as Confucius claims that “the man of humaneness (ren) is one who, desiring to sustain himself, sustains others.” This essay concludes that a new interpretation of the Confucian text and its meaning would help to encourage more people to volunteer as organ donors.DOWNLOAD HISTORY | This article has been downloaded 2088 times in Digital Commons before migrating into this platform.

AbstractFrom the late nineteenth century onwards, a new range of European and American technologies, powered by electricity and gas, and intended for use on the body and in the home—especially appliances for the domestic kitchen—began to appear in Manila. Electro-mechanical vibratory devices and steam-powered massagers for the body; hair waving and curling machines; and a multitude of technologies for the domestic kitchen, from stoves and water heaters to a gamut of electric and gas gadgetry that included percolators, boilers, electric waffle-irons, grills, and refrigerators (or ice-boxes, their precursor) were targeted largely at the affluent female consumer with promises to improve her physical appearance and health or make her daily life more comfortable. Their introduction and impact in the Philippines can tell a number of compelling stories—the desirability of European or American bourgeois culture, how the trappings of Western lifestyles were imagined, the extent to which the use and purchase of certain technologies aimed at replicating or emulating those lifestyles, or, as this paper explores, the gendered technological infrastructure of the ‘good life’. In this story, modern technologies designed for domestic settings and for use on women's bodies made manifest a myriad of desires and aspirations—prestige, status, cosmopolitanism, modernity, and urbanity. They also articulated a particular sensuousness and pleasure. Electro-vibratory devices, hair styling machines, and kitchen appliances could be experienced by all the senses and thus exerted a visceral appeal; their use proclaimed an enthusiasm for modern technology which, for the first time, emphasized the relevance of modern technology to women's everyday lives by the transformative effects they promised.

Artificial Hand

Currently, the number of amputees in the United States is estimated at 1.7 million people [1], and of those 1.7 million people, only approximately 300,000 are upper limb amputees [2]. However, the number of amputees is growing at a rate of more than 18,000 people per year [3]. Although the body powered and myoelectric prosthetics have been invented to provide a cosmetic solution and functionally allow the user to employ leverage or grasp an object, there are no marketed products which provide tactile feedback. Often amputees will not use their current prosthetics due to their unnatural feel. In terms of functional use of the prosthetics, reports show as low as 29% of amputees with prosthetics make use of the grasp feature [4]. Due to the general lack of user satisfaction, it is necessary to improve the prosthetic market by incorporating sensory feedback into upper limb prosthetics so that the user feels like they are using their own arm. With the incorporation of sensory-motor coordination, amputees’ reliance on visual information to be aware of the artificial hand and arm will be decreased, thereby, decreasing their cognitive load [5]. Additionally, due to the increased feedback from the arm regarding the environment, the amputee will be able to use their artificial limb more effectively and with more of native feel.

Tactile Localization

AbstractMany natural behaviors involve closed feedback loops in which ongoing sensory input refines motor behavior. Previous research on tactile localization, however, has implemented localization as open-loop behavior. For instance, participants indicate a touched position on a silhouette shape of the body or on an occluding board mounted above the hand. Such studies have suggested that humans often make large errors when localizing touch on the skin, or that “perceptual body representations” are distorted. However, by artificially preventing tactile feedback from the target body area, the natural action-perception loop is interrupted. Therefore, these localization approaches may underestimate individuals’ localization ability and draw erroneous conclusions about the role and precision of body representations. Here, we tested tactile localization in a natural setting, in which participants first received brief touches on their left forearm and then searched for the target location by moving the right index finger across the skin. Tactile search reduced localization error when the searching finger was far from, but not when it was near the target, resulting in a remaining error of 1-2 cm. Error reduction was absent when participants searched on an acrylic barrier mounted above the arm, suggesting that availability of tactile feedback on the target arm but not proprioceptive and motor signals of the searching arm determined precision, thus confirming the pivotal role of closed-loop sensory feedback for tactile localization. We suggest that actively produced online tactile feedback routinely refines coarse spatial body representations, similar to the refinement of sparse spatial representations in visual memory through consecutive saccades.

Hair cornucopia in Balzac’s Contes drôlatiques In order to re‐evaluate the constraints imposed by literary censorship to writers and painters after the Renaissance until the Restauration and Orleanist monarchy, we offer this comparative analysis of the treatment of hair, hair style, body hair in Balzac’s La Comédie humaine where Balzac has to restrain himself to reach success and in his Contes drôlatiques, which takes place in the medieval period and the Renaissance, and emulates the language and crudity of the time. Balzac’s point of view is particularly interesting first because he is quite knowledgeable of literary and artistic expressions during the medieval age and the Renaissance with Aretino and Rabelais, and second because he lived during the time when the daguerreotype appeared and made possible the representation of the body as it is, attempt that the anatomists of the Renaissance had also played with. However, with their droll stories, neither was Rabelais an anatomist nor was Balzac a common man.
