Cysteine （CSH） readily stabilizes cadmium sulfide quantum dots （CdS QDs） that grow in aqueous buffered solutions. The oxidation of CSH by hydrogen peroxide （H202） at room temperature yields cystine （CSSC）, which is less efficient in stabilizing CdS QDs compared to CSH. Herein, we demonstrate that such oxidation causes a decrease in the formation rate of CSH-capped CdS QDs from Cd^2＋ and S^2- ions. For the first time, we combined the oxidation of CSH with the glucose oxidase （GOx）-assisted biocatalytic oxidation of D-glucose, which leads to a buildup of H2O2 in the reaction mixture. The enzymatically modulated in situ growth of CdS QDs was monitored using two techniques： fluorescence spectroscopy and photoelectrochemical （PEC） analysis. This system enables quantification of GOx and glucose in human serum.

Framed structures are usually infilled with masonry walls. They may cause a significant increase in both stiffness and strength, reducing the deformation demand and increasing the energy dissipation capacity of the system. On the other hand, irregular arrangements of the masonry panels may lead to the concentration of damage in some regions, with negative effects; for example soft story mechanisms and shear failures in short columns. Therefore, the presence ofinfill walls should not be neglected, especially in regions of moderate and high seismicity. To this aim, simple models are available for solid infills walls, such as the diagonal no-tension strut model, while infilled frames with openings have not been adequately investigated. In this study, the effect of openings on the strength and stiffness of infilled frames is investigated by means of about 150 experimental and numerical tests. The main parameters involved are identified and a simple model to take into account the openings in the infills is developed and compared with other models proposed by different researchers. The model, which is based on the use of strength and stiffness reduction factors, takes into account the opening dimensions and presence of reinforcing elements around the opening. An example of an application of the proposed reduction factors is also presented.

Nonalcoholic fatty liver disease(NAFLD) is the most common cause of chronic liver disease in the industrialized world. The prevalence of NAFLD is increasing, becoming a substantial public health burden. NAFLD includes a broad spectrum of disorders, from simple conditions such as steatosis to severe manifestations such as fibrosis and cirrhosis. The relationship ofNAFLD with metabolic alterations such as type 2 diabetes is well described and related to insulin resistance, with NAFLD being recognized as the hepatic manifestation of metabolic syndrome. However, NAFLD may also coincide with endocrine diseases such as polycystic ovary syndrome, hypothyroidism, growth hormone deficiency or hypercortisolism. It is therefore essential to remember, when discovering altered liver enzymes or hepatic steatosis on radiological exams, that endocrine diseases can cause NAFLD. Indeed, the overall prognosis of NAFLD may be modified by treatment of the underlying endocrine pathology. In this review, we will discuss endocrine diseases that can cause NALFD. Underlying pathophysiological mechanisms will be presented and specific treatments will be reviewed.

Alice Notley’s Culture of On e(2011)is a“poet’s novel”about a woman who lives in the dump of a *** desert *** female character who“inhabits”the dump-and this poet’s novel-is both metonym for and guide into the lost representation of“the abject,”a concept developed by Julia Kristeva as a psychic state of horror and response to that which lies outside culturally“normalized”subjects and objects,and our“desire for meaning.”Utilizing her dump refuse for its materials,the main character,Marie,creates her own“culture of one,”standing as figure for the artist/writer plunging not“meaning”but meaninglessness and its abject association with death,which is prefigured as the unclean,the improper,rejected body parts,deviant“non-existent”personae-and,ultimately,Marie’s figural status as marginal inhabitant/“culture remaker”/older woman/multi-media“poet”*** traditional conventions of novelistic character development,plot,and visual description,Notley’s“poet’s novel”formally engages in what Viktor Shkolvsky,in his well-known essay“Art as Technique,”terms“defamiliarization”or“strangeness”(“ostranenie,”in Russian),including those principles he cites of“deceleration”and“deviation of the norm.”Notley’s work twists the binary logic implied in Shkolvsky’s“deviation”versus“norm”further by revealing abjection’s“strangeness”in the poet’s novel itself as form,”a text that is always becoming its own site of the linguistic abject,never codifying identity,or the interpreted known.
