Del(22q11) is a common microdeletion syndrome with an extremely variable phenotype. Besides classical manifestations, such as velocardiofacial (Shprintzen) or DiGeorge syndromes, del(22q11) syndrome may be associated with unusual but probably causally related anomalies that expand its phenotype and complicate its recognition. We report here three children with the deletion and a chronic, erosive polyarthritis resembling idiopathic cases of juvenile rheumatoid arthritis (JRA). Patient 1, born in 1983, initially presented with developmental delay, facial dysmorphism, velopharyngeal insufficiency, and severe gastro-oesophageal reflux requiring G tube feeding. From the age of 3 years, he developed JRA, which resulted in severe restrictive joint disease, osteopenia, and platyspondyly. Patient 2, born in 1976, had tetralogy of Fallot and peripheral pulmonary artery stenosis. She developed slowly, had mild dysmorphic facial features, an abnormal voice, and borderline intelligence. JRA was diagnosed at the age of 5 years. The disorder followed a subacute course, with relatively mild inflammatory phenomena, but an extremely severe skeletal involvement with major osteopenia, restrictive joint disease (bilateral hip replacement), and almost complete osteolysis of the carpal and tarsal bones with phalangeal synostoses, leading to major motor impairment and confinement to a wheelchair. Patient 3, born in 1990, has VSD, right embryo-toxon, bifid uvula, and facial dysmorphism. She developed JRA at the age of 1 year. She is not mentally retarded but has major speech delay secondary to congenital deafness inherited from her mother. In the three patients, a del(22q11) was shown by FISH analysis. These observations, and five other recently published cases, indicate that a JRA-like syndrome is a component of the del(22q11) spectrum. The deletion may be overlooked in those children with severe, chronic inflammatory disorder. [less ▲]

A significant proportion of sexual delinquency being committed by juveniles, various fields of research have studied this topic. Still, little is known about the relation between the linguistic ability and the cognitive functioning of this specific youth. Rooted in scientific works which have explored indirectly the point, this poster attempt to question the quality of language as a mean to find out how their mentalization occurs, but also to question how their cognitive processes (e.g. empathy) influence their language. These hypothesis are to be tested soon with a clinical sample of 47 participants and with different measures (e.a. MACI, verbal IQ, IRI). Hence, the opportunity to evaluate, among others, empathy deficits and cognitive distortions through language can be considered a promising approach allowing new perspectives for prevention, assessment and treatment of juvenile sexual offenders.

OBJECT: A consecutive series of 28 "operated" juxtafacet cysts is reported. We emphasize the clinical and radiological aspects leading to diagnosis. We also discuss the results of the surgical treatment. MATERIAL AND METHODS: Medical information and radiological studies involving 28 patients were analyzed. Each patient has been operated on by decompressive laminectomy and resection of the cyst. The diagnosis was always confirmed by a pathological examination. The cyst most frequently occurred at the L4-L5 level (n = 18), and seldom at the L5-S1 (n - 6) or L3-L4 (n - 4) levels. RESULTS: The differential diagnosis from other pathological causes responsible for a radicular compression could not be done by physical examination. Spine X-rays or myelogram were nonspecific. Computed Tomography or CT-myelography could help in the diagnosis but MR imaging was the most sensitive. In our series, the respective sensitivities of these techniques are 56, 42 and 77%. The preoperative diagnosis was correct in 18 patients (64%). The cyst was sometimes adherent to the underlying dura, then significantly increasing the risk of dural tear and spinal fluid leak, especially when located at L3-L4 level. Surgical ablation lead to a complete recovery or an important improvement in 26 patients. CONCLUSIONS: The diagnosis of the juxtafacet cyst of the lumbar spine is better achieved by MRI. Surgery is the gold standard treatment, safe and long-term effective. When a total cyst removal with an internal facetectomy are performed, recurrence is exceptional. [less ▲]

We investigated the properties of several peptides with sequences related to LWYIK, a segment found in the gp41 protein of HIV and believed to play a role in sequestering this protein to a cholesterol-rich domain in the membrane. This segment fulfills the requirements to be classified as a CRAC motif that has been suggested to predict those proteins that will partition into cholesterol-rich regions of the membrane. All of the peptides were studied with the terminal amino and carboxyl groups blocked, i.e., as N-acetyl-peptide-amides. Effects of cholesterol on the intensity of W emission generally parallel DSC evidence of sequestration of cholesterol. Modeling studies indicate that all of these peptides tend to partition with their mass center at the membrane interface at the level of the hydroxyl of cholesterol. Interaction with cholesterol is dual: van der Waals interactions between mainly hydrophobic surfaces and electrostatic stabilization of the cholesterol OH group. Thus, both experiments and modeling studies indicate that the preference of CRAC motifs for cholesterol-rich domains might be related to a membrane interfacial preference of the motif, to a capacity to wrap and block the cholesterol polar OH group by H-bond interactions, and to a capacity for peptide aromatic side chains to stack with cholesterol. These results were supported by studies of single mutations in the gp41 protein of HIV-1, in which L(679) is replaced with I. Despite the similarity of the properties of these amino acid residues, this single substitution resulted in a marked attenuation of the ability of JC53-BL HeLa-based HIV-1 indicator cells to form syncytia.

We present how it is achieved to mount a double prism in the filter wheel of MIRIM - the imager of JWST’s Mid Infrared Instrument. In order to cope with the extreme conditions of the prisms’ surroundings, the low resolution double prism assembly (LRSDPA) design makes high demands on manufacturing accuracy. The design and the manufacturing of the mechanical parts are presented here, while ’Manufacturing and verification of ZnS and Ge prisms for the JWST MIRI imager’ are described in a second paper [1]. We also give insights on the astronomical possibilities of a sensitive MIR spectrometer. Low resolution prism spectroscopy in the wavelength range from 5-10 microns will allow to spectroscopically determine redshifts of objects close to/at the re-ionization phase of the universe.

beta-Lactamase K1 was purified from Klebsiella pneumoniae SC10436. It is very similar to the enzyme produced by Klebsiella aerogenes 1082E and described by Emanuel, Gagnon & Waley [Biochem. J. (1986) 234, 343-347]. An active-site peptide was isolated after labelling of the enzyme with tritiated beta-iodopenicillanate. A cysteine residue was found just before the active-site serine residue. This result could explain the properties of the enzyme after modification by thiol-blocking reagents. The sequence of the active-site peptide clearly established the enzyme as a class A beta-lactamase. [less ▲]
