Abstract
Persons with MS have the highest unemployment rates compared to other chronic diseases. We want to develop a MS Toolkit with several aids for persons with MS to help them gain a sustainable employment with sufficient and permanent attention and guidance for the daily obstacles in the workplace. Therefore, the opportunities and bottlenecks were mapped through a survey with persons with MS and employers, a diary and expert interviews. There were 3 major problems identified: Persons with MS find it difficult to ask for help in time; they have little or no concrete knowledge about who they can turn to for support and healthcare professionals do not always possess the expertise to guide their patients through problems experienced on the work floor. These problems were used as fundaments in a cocreation session to create the content of the MS Toolkit: a screening tool and dashboard. The screening tool ensures an annual reflection of the work situation. The dashboard links each problem to the most appropriate service.

Abstract
PRIMARY OBJECTIVE The objective of this study was to design an instrument to screen for burden in the daily life of both the client with acquired brain injury (ABI) and their nonprofessional caregiver. RESEARCH DESIGN Exploratory research Methods and Procedures: Based on a survey amongst stakeholder organizations, the FINAH-instrument is designed as a digital self-assessment questionnaire, based on ICF-framework. A test survey of the FINAH instrument is conducted on both clients, nonprofessional caregivers and healthcare professionals. MAIN OUTCOMES AND RESULTS The relative burden per item for clients and nonprofessional caregivers is most prominent in the domains of fatigue, cognitive and emotional consequences, self-care and mobility. The estimation of burden for clients and nonprofessional caregiver by healthcare professionals showed an overall 65% correct estimation by the healthcare professional. 19% of the items showed underestimation of burden, while 16% showed overestimation. CONCLUSIONS These results show that FINAH can ameliorate the estimation of the health care professional on the self-assessed burden of clients and nonprofessional caregivers, thus substantiating a more client-centred approach.

Abstract
The positioning of a soft silicone collar around the rabbit carotid artery induces intimal thickening. We investigated to which extent occlusion of the vasa vasorum, damage of the perivascular nerve network, and/or changes in blood flow velocity contribute to intimal thickening. To this end, collars with different bores (diameter of inlet and outlet) were positioned around the carotid artery of male rabbits for 14 days. In another experiment, 75% of the wall of fitting collars was removed (open collar). In the midcollar region, the cross-sectional area of the intima reached a maximum (72 +/- 14 mm2/1000) when the endings of the collar fitted the artery closely. Removal of the side wall of these fitting collars reduced intimal thickening by 90%. Examination of unoperated carotid arteries never showed penetration of the adventitia or the media by vasa vasorum. The perivascular neuronal network in the region surrounded by a closed or an open collar was almost completely lost as compared with the zones outside the collar. Both the closed and open collar slightly bent the artery and increased the peak systolic velocity, measured with pulsed color Doppler after 6 hours, to a similar extent as compared with the proximal zone outside the collar. After 2 weeks, the peak systolic velocity within both the closed and open collar was partly normalized and was statistically not different from the proximal zone outside the collar. In conclusion, the geometry of the collar influenced the extent of intimal thickening, whereby more intimal thickening was obtained with a collar whose endings fit the carotid artery, rather than with a loose collar. Moreover, a closed structure was essential. The results obtained with the open collar exclude occlusion of vasa vasorum, damage of the perivascular neuronal network, kinking of the artery, and changes in blood flow velocity as major factors in the collar-induced intimal thickening. Our findings are consistent with the possibility that intimal thickening is the consequence of the combination of both vascular injury and hindrance of transmural flow by the collar. The obstruction of transmural fluid transport may then lead to retention of toxic metabolites, and/or cytokines within the segment enclosed by the collar.

Abstract
Numerous characterizations were performed on 120-nm thick evaporated SiO(2) layers in order to understand how their features change as a function of deposition conditions and time. Density decreases with increasing deposition pressure. It governs all the layer properties (refractive index, hardness, and stress). In situ stress measurements show that stress can be divided into intrinsic and water-induced components, respectively linked to local density (outside the pores) and porosity. Intrinsic stress increase with decreasing pressure is explained by a diminution of the Si-O-Si bond angle (IR measurements). Long-term evolution is characterized by stress relaxation related to Si-O-Si strained bond hydrolysis.

Abstract
After growth of six strains of mycobacteria on Sauton medium in the absence of added Zn2+, cell yields were lowered, to between 22% and 67% of the yields obtained when Zn2+ (5 microM) was added. Two immunodominant proteins, named P64 and P32 (antigens of 62-65 kDa and 29-33 kDa, respectively) were abundant in culture filtrates after growth of mycobacteria. P64 was present at elevated concentrations (showing a 9- to 16-fold increase as a percentage of the total protein released) after Zn2+-deficient growth of five of the six strains studied; in Mycobacterium tuberculosis it represented 25% of all released proteins. However, little P64 was detected in culture filtrates of M. fortuitum and of M. phlei grown under Zn2+ deficiency, and in the latter there was no increase of P64 during Zn2+ deficiency.

Abstract
Twenty-one patients treated for active tuberculosis were examined for immune reactivity to purified protein derivative (PPD) and to a purified 32-kDa protein antigen (P32) from Mycobacterium bovis, strain BCG. Lymphoproliferation of peripheral blood leucocytes to PPD and P32 was positive in 95% and 71% of the patients respectively. A positive IFN-gamma response was detected in 62% against PPD and in 48% against P32. Low blastogenesis and IFN-gamma production were observed, especially in patients with poor general health and advanced tuberculous lesions. Twelve out of twelve (100%) of the tuberculin-positive healthy volunteers responded to PPD and P32 with mean lymphoproliferation and IFN-gamma values that were higher than in the patient group. Twelve tuberculin-negative control subjects were completely unreactive to PPD and P32 antigen. On the other hand, IgG antibodies in the serum were detected in 95% of the patients against PPD, in 77% of the patients against P32 but in none of the tuberculin-positive or negative healthy volunteers. The highest IgG levels against PPD were found in those patients with the lowest in vitro lymphoproliferation and IFN-gamma production (r = -0.54; P less than 0.05). Nonspecific interferon production following induction with Newcastle disease virus, Corynebacterium parvum, or phytohaemagglutinin was comparable in the control and patient groups. Finally, low IFN-alpha titres were detected in the serum of about 50% of the patients.

Abstract
An immunogenic protein called P32 has been purified from Sauton zinc deficient culture filtrate of Mycobacterium bovis BCG using successively hydrophobic chromatography on Phenyl-Sepharose, ion exchange on DEAE-Sephacel and molecular sieving on Sephadex G-100. The final preparation was found to be homogeneous as based on several analyses. This P32 protein was a constituent of BCG cells grown in normal conditions. It represented about 3% of the soluble fraction of a cellular extract, and appeared as the major protein released in normal Sauton culture filtrate. This protein was found to have a molecular weight of 32,000 by SDS-polyacrylamide gel electrophoresis and in molecular sieving. Its amino acid composition showed an abundance of acidic amino acids (or their amides). The NH2-terminal amino acid sequence (6 amino acids) was determined. Purified P32 was tested by various crossed immunoelectrophoresis techniques, and was shown to belong to the antigen 85 complex in the reference system for BCG antigens. It was more precisely identified as antigen 85A. The protein antigen elicited a weak delayed hypersensitivity reaction in guinea pigs sensitized with heat-killed or living BCG. No delayed hypersensitivity reaction was observed in living BCG sensitized mice, however, it induced significant amounts of gamma interferon in cultured spleen cells from BCG-sensitized mice. Moreover, P32 either pure or as part of BCG soluble extract promoted substantial antibody levels when injected in rabbits.

Abstract
An immunogenic and skin-reactive protein called P64 was purified from Sauton zinc-deficient culture filtrate of Mycobacterium bovis BCG by using successively hydrophobic chromatography on phenyl-Sepharose, ion exchange on DEAE-Sephacel, and molecular sieving on Sephadex G-200. The final P64 preparation was found to be homogeneous based on several analyses. Protein P64 was a constituent of BCG cells since it was present in soluble cellular extract from normally grown BCG cells. It represented 8 to 9% of the soluble proteins of the extract and appeared as the major soluble protein antigen of BCG. This protein was found to have a molecular weight of 64,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, but in molecular sieving it eluted at a volume corresponding to a molecular weight of 246,000. An abnormal UV spectrum was observed for this protein. Its amino acid composition showed an abundance of acidic amino acids (or their amides). Aromatic amino acids represented only 3% of the total amino acid residues. The NH2-terminal amino acid sequence of this protein (10 amino acids) was determined. Its sugar content measured with the phenol-sulfuric acid test was lower than 0.3% (wt/wt.) Isolated P64 was tested by various crossed-immunoelectrophoresis techniques and was shown to correspond to antigen 82 in the reference system for BCG antigens. The protein antigen P64 elicited a delayed cutaneous reaction in guinea pigs sensitized with either living or heat-killed BCG. Its potency in skin reaction was, respectively, two- and threefold that of the BCG purified protein derivative. The two types of sensitization used for skin test reactions promoted significant immunoglobulin G antibody production against the protein antigen P64 in guinea pigs 7 weeks after sensitization.
