Le caryotype de Crocidura bolivari (Mammalia, Soricidae) Morales Agacino, 1934 (Mammalia, Soricidae)

The karyotype of Crocidura bolivari from Morocco is characterized by 2n = 50, NF = 66 and NFa = 62, and therefore corresponds to that of Crocidura occidentalis (Pucheran, 1855). Preliminary results on the standard genetic distances revealed by enzyme electrophoresis confirm the close relationship with the African giant shrews.

A Legislator under Surveillance: The Creation and Implementation of Swiss Banking Legislation 1910-1934

This paper analyses how banking regulation was introduced in Switzerland - one of the world's most prominent financial centres - which remained in place until the beginning of the twenty-first century. It shows that the law adopted on 8 November 1934 is a perfect example of capture of the regulator by the regulated. Essentially a political response in the context of the economic crisis of the 1930s, it largely reflected the interests of banking circles by limiting the intervention of the State as much as possible. The introduction of the new legislation was facilitated by the temporary weakness of Swiss banking circles, as they depended on the State to delay or prevent the collapse of many major credit institutions. They did not manage to derail the law as they had two decades earlier when they scuppered the federal bill on banks drawn up between 1914 and 1916. But this time they were better organized and more united, and intervened all the more effectively in the legislative process itself. The 1934 law is thus distinctive in that it made no structural changes to the architecture of the financial centre but merely codified its practices through flexible legislation meant to reassure the public. The law was aimed less at controlling banking activity than at keeping - thanks to skilfully calibrated political concessions - the State from having to intervene more directly in the internal management of banks or in the fixing of interest rates and the export of capital.

Older persons' perceptions of general practitioner or specialist primary care physicians : same point of view?

BACKGROUND: Identification of a Primary Care Physician (PCP) by older patients is considered as essential for the coordination of care, but the extent to which identified PCPs are general practitioners or specialists is unknown. This study described older patients' experiences with their PCP and tested the hypothesis of differences between patients who identify a specialist as their PCP (SP PCP) and those who turn to a general practitioner (GP PCP). METHODS: In 2012, a cross-sectional postal survey on care was conducted in the 68+ year old population of the canton of Vaud. Data was provided by 2,276 participants in the ongoing Lausanne cohort 65+ (Lc65+), a study of those born between 1934 and 1943, and by 998 persons from an additional sample drawn to include the population outside of Lausanne or born before 1934. RESULTS: Participants expressed favourable perceptions, at rates exceeding 75% for most items. However, only 38% to 51% responded positively for out-of-hours availability, easy access and at home visits, likelihood of prescribing expensive medication if needed, and doctors' awareness of over-the-counter drugs. 12.0% had an SP PCP, in 95.9% specialised in a discipline implying training in internal medicine. Bivariate and multivariate analyses did not result in significant differences between GP and SP PCPs regarding perceptions of accessibility/availability, doctor-patient relationship, information and continuity of care, prevention, spontaneous use of the emergency department or ambulatory care utilisation. CONCLUSIONS: Experiences of old patients were mostly positive despite some lack in reported hearing, memory testing, and colorectal cancer screening. We found no differences between GP and SP PCP groups.

Cognitive and Emotional Deficits Associated with Minor and Serious Delinquency in High-Risk Adolescents

This study aims at evaluating how minor and serious delinquency relates to cognitive and emotional functioning in high-risk adolescents, taking problematic substance use into account. In 80 high-risk adolescent males (13-19 years), the frequency of minor and serious offences committed over the last year was predicted, in multiple regression analyses, from problematic substance use, intellectual efficiency, trait impulsivity, alexithymia (inability to express feelings in words), and cognitive coping strategies. Both minor and serious delinquency were more frequent in adolescents with more problematic substance use and higher intellectual efficacy. Minor delinquency was further related to a tendency to act out when experiencing negative emotions, and difficulties in focusing energy on instrumental action when under stress; while serious delinquency was predominantly and strongly related to rigid and dichotomous thinking. The results underline the heterogeneous nature of delinquency, minor offences being primarily associated with emotional regulation deficits, while major offences are related with a lack of cognitive flexibility.

Epithelium-Intrinsic NAIP/NLRC4 Inflammasome Drives Infected Enterocyte Expulsion to Restrict Salmonella Replication in the Intestinal Mucosa.

The gut mucosal epithelium separates the host from the microbiota, but enteropathogens such as Salmonella Typhimurium (S.Tm) can invade and breach this barrier. Defenses against such acute insults remain incompletely understood. Using a murine model of Salmonella enterocolitis, we analyzed mechanisms limiting pathogen loads in the epithelium during early infection. Although the epithelium-invading S.Tm replicate initially, this intraepithelial replicative niche is restricted by expulsion of infected enterocytes into the lumen. This mechanism is compromised if inflammasome components (NAIP1-6, NLRC4, caspase-1/-11) are deleted, or ablated specifically in the epithelium, resulting in ∼100-fold higher intraepithelial loads and accelerated lymph node colonization. Interestingly, the cytokines downstream of inflammasome activation, interleukin (IL)-1α/β and IL-18, appear dispensable for epithelial restriction of early infection. These data establish the role of an epithelium-intrinsic inflammasome, which drives expulsion of infected cells to restrict the pathogen's intraepithelial proliferation. This may represent a general defense mechanism against mucosal infections.

Defining the site of light perception and initiation of phototropism in Arabidopsis.

Phototropism is an adaptive response allowing plants to optimize photosynthetic light capture. This is achieved by asymmetric growth between the shaded and lit sides of the stimulated organ. In grass seedlings, the site of phototropin-mediated light perception is distinct from the site of bending; however, in dicotyledonous plants (e.g., Arabidopsis), spatial aspects of perception remain debatable. We use morphological studies and genetics to show that phototropism can occur in the absence of the root, lower hypocotyl, hypocotyl apex, and cotyledons. Tissue-specific expression of the phototropin1 (phot1) photoreceptor demonstrates that light sensing occurs in the upper hypocotyl and that expression of phot1 in the hypocotyl elongation zone is sufficient to enable a normal phototropic response. Moreover, we show that efficient phototropism occurs when phot1 is expressed from endodermal, cortical, or epidermal cells and that its local activation rapidly leads to a global response throughout the seedling. We propose that spatial aspects in the steps leading from light perception to growth reorientation during phototropism differ between grasses and dicots. These results are important to properly interpret genetic experiments and establish a model connecting light perception to the growth response, including cellular and morphological aspects.
