Insights into the timing of repeated testing after treatment for Chlamydia trachomatis: data and modelling study

The objective of this study was to determine the optimal time interval for a repeated Chlamydia trachomatis (chlamydia) test.

Influence of cristalline structure of two minerals clays of type 1/1 on their pozzolanic power

Two clayey materials, one provided by a patner in mineral sector and the other coming from Balengou (West Region Cameroon) were subject of a comparative study in order to evaluate the influence of their crystalline structure on their pozzolanic property. These two natural materials were preliminary enriched in clay minerals by wet sieving and the fractions obtained are denoted K and H respectively. K and H were calcinated at 700 °C, with a heating rate of 5 °C/min and 10 hours dwell at the peak temperature, the products obtained were named MK and MH. Samples K, H, MK and MH were physicochemically characterized by the chemical (ICP), thermal(TGA/DTA) and mineralogical (DRX and Spectrometry IR) analyses together with the measurement of specific surface (BET), crystallinity and the pouzzolanicity test. The results confirmed K as a kaolinitic and H halloysic clay. The kaolinite and the halloysite respectively presented in these clayey materials exhibited a poor crystallinity, but the degree of disorder is higher in K than in H. These results were largely affected by the significant fraction of gibbsite in kaolinitic clay K. At the crude state, the pozzolanic activity of the material H is weak compared with that of K, but the heat treatment makes largely improve this property for both samples.

Preexisting BCG-specific T cells improve intravesical immunotherapy for bladder cancer

Therapeutic intravesical instillation of bacillus Calmette-Guérin (BCG) is effective at triggering inflammation and eliciting successful tumor immunity in patients with non-muscle invasive bladder cancer, with 50 to 70% clinical response. Therapeutic success relies on repeated instillations of live BCG administered as adjuvant therapy shortly after tumor resection; however, the precise mechanisms remain unclear. Using an experimental model, we demonstrate that after a single instillation, BCG could disseminate to bladder draining lymph nodes and prime interferon-γ-producing T cells. Nonetheless, repeated instillations with live BCG were necessary for a robust T cell infiltration into the bladder. Parenteral exposure to BCG before instillation overcame this requirement; after the first intravesical instillation, BCG triggered a more robust acute inflammatory process and accelerated T cell entry into the bladder, as compared to the standard protocol. Moreover, parenteral exposure to BCG before intravesical treatment of an orthotopic tumor markedly improved response to therapy. Indeed, patients with sustained preexisting immunity to BCG showed a significant improvement in recurrence-free survival. Together, these data suggest that monitoring patients' response to purified protein derivative, and, in their absence, boosting BCG responses by parenteral exposure before intravesical treatment initiation, may be a safe and effective means of improving intravesical BCG-induced clinical responses.

Psychological Real Estate: Fractured Female Identity in the Victorian Novel

"Psychological Real Estate: Fractured Female Identity in the Victorian Novel" examines the use of domestic space in three Victorian novels, Charlotte Bronte's Jane Eyre (1847), Mary Elizabeth Braddon's Lady Audley's Secret (1862), and George Eliot's Middlemarch (1871-2). Because Victorian gender identity was conceived of in spatial terms, this thesis explores how the three female authors use complicated domestic environments to engage the problem of conventional Victorian femininity. In the Victorian mindset, a woman's place is confined to the home, or private sphere; however, even the private sphere is intruded upon by public spaces. Expected to conform to the Victorian formulation of femininity in public spaces within the home, women had only their private spaces to cultivate the unique, individualistic aspects of their selves. This thesis explores the ways in which the female protagonists negotiate these gender encoded spaces to argue that because Victorian women had to maintain separate and often disparate identities within domestic space, their identities became problematically fractured. Additionally, in each of these texts, the authors use the failure or loss of the estate, the structure which rigidly upholds the gendered binaries, to expose the harm such fracturing identity formulation caused for Victorian society as a whole. This thesis concludes by examining the final residences of the female characters and arguing that the authors use these final private spaces to assert more feminist re-envisionings of their society's construction of femininity.

"She Was Not Even Normal": Unreliable Narratives of Female Insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea

In my thesis, I interrogate narrative reliability related to depictions of female insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea. By subjecting the trustworthiness of her storytelling to criticism, especially as regards the concealed madwoman, Bertha Mason, Jane's narration is revealed as unstable, offering problematic insight into a character long considered unflinchingly honest. In du Maurier's later literary adaptation of Jane Eyre, Bertha's parallel character, the eponymous Rebecca, comes to the fore, while the novel's unnamed narrator remains in the shadows, and bases much of her storytelling upon hearsay, rather than the "autobiography" of Jane Eyre. The most transparent narrative voice, however, is Antoinette, the main character of Wide Sargasso Sea, the 1966 prequel to Jane Eyre. Despite her madness, Antoinette's narration makes no attempt at dissemblance, speaking forthrightly about her marriage and experience, proving a truthful narrator and openly rejecting the marginal status the earlier narrators try desperately to hide.

Sexing the Male: Manifestations of Masculinity in Jane Eyre, Wuthering Heights, and Villette

Abstract: This project considers Emily and Charlotte Brontë's constructions of masculinity in Jane Eyre, Wuthering Heights, and Villette. There is a vast proliferation of scholarship focusing on gender in the Victorian Era, but as much of this criticism focuses on women, the analysis of heterosexual masculinity in these novels provides a unique perspective on the complexities involved in gender constructions during this period. Masculine identity was in a transitory state in the early nineteenth century, as Romantic values were replaced by Victorian conceptions of masculinity, largely influencing the expectations of men. This paper argues that based on an understanding of femininity and masculinity as defined in relation to each other, the Brontë heroes look to the female characters as a source of stability to define themselves against, constructing a stagnant feminine role to frame an understanding of how masculinity was changing. The female characters resist this categorization, however, never allowing the men to fully classify them into stable feminine roles, which leads both shifting gender roles to intertwine and collapse in the novels, undermining any conceptualization of a stable or universal understanding of gender. The paper considers the role of masculinity based in class, relationships with women, and the understanding of sexual passion, to argue that the Brontës' portrayal of men emulates the anxieties surrounding the shift from Romantic to Victorian values of manliness, ultimately rejecting any stable definition of the nineteenth-century man.

Farming environments and childhood atopy, wheeze, lung function, and exhaled nitric oxide

Previous studies have demonstrated that children raised on farms are protected from asthma and allergies. It is unknown whether the farming effect is solely mediated by atopy or also affects nonatopic wheeze phenotypes.

Patients with mild traumatic brain injury: immediate and long-term outcome compared to intra-cranial injuries on CT scan

BACKGROUND: Mild traumatic brain injury (MTBI) defined as Glasgow Coma Scale (GCS) 14 or 15 has shown contradictory short- and long-term outcomes. The objective of this study was to correlate intra-cranial injuries (ICI) on CT scan to neurocognitive tests at admission and to complaints after 1 year. METHODS: Two hundred and five patients with MTBI underwent a CT scan and were examined with neurocognitive tests. After 1 year complaints were assessed by phone interviews. RESULTS: The neurocognitive tests in 51% of the patients showed significant deficits; there was no difference for patients with GCS 14-15, nor was there a difference between patients with ICI to patients without. After 1 year patients with ICI had significantly more complaints than patients without ICI, the most frequent complaint was headache and memory deficits. CONCLUSIONS: No correlation was found between GCS or ICI and the neurocognitive tests upon admission. After 1 year, patients with ICI have significantly more complaints than patients without ICI. No cost savings resulted by doing immediate CT scan on all.

Interactional behaviour as a marker for screening patients with environment-related complaints

BACKGROUND: Adequate assessment of symptoms of patients suffering from environmental illnesses requires appropriate procedures such as psychological and psychiatric diagnostics, medical screening and a thorough analysis of noxious environmental factors. The Basel pilot research project established a multi-methodological assessment procedure that meets these criteria. However, an exhaustive three-fold analysis is very costly in terms of both equipment and personnel, and hence the need for a heuristic approach and pre-screening persists. METHOD: The three-fold diagnostic approach was preceded by a structured psychodynamic interview; the findings were used to construct a new profile of the patient's interactional behaviour (IB) in conjunction with the interviewer's countertransference. The extent to which this new profile could predict the results of the multi-method assessment was then assessed. RESULTS: A low level of IB on the part of the patient significantly predicted the degree of stress and the extent of the psychiatric diagnosis, including personality disorders. A negative IB was associated with negative personality traits. Furthermore, a high level of IB implied more medical, but not more environmental, findings which could plausibly be related to the patient's complaints. CONCLUSIONS: Assessment of patients' IB in conjunction with one's own countertransference is very helpful as a preliminary heuristic approach and may lead to consequences for treatment and therapy. Therefore, the training provided for experts who deal with patients suffering from environment-related complaints should place more specific emphasis on assessing patients' behaviour and on incorporating information gathered from countertransference. Nevertheless, an interdisciplinary assessment including medical, psychological/psychiatric, and environmental expertise remains mandatory for adequate and satisfactory diagnosis of patients with environment-related complaints.
