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 ▲]

We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hr: K2-22b. The highly variable transit depths, ranging from ∼0% to 1.3%, are suggestive of a planet that is disintegrating via the emission of dusty effluents. We characterize the host star as an M-dwarf with Teff ≃ 3800 K. We have obtained ground-based transit measurements with several 1-m class telescopes and with the GTC. These observations (1) improve the transit ephemeris; (2) confirm the variable nature of the transit depths; (3) indicate variations in the transit shapes; and (4) demonstrate clearly that at least on one occasion the transit depths were significantly wavelength dependent. The latter three effects tend to indicate extinction of starlight by dust rather than by any combination of solid bodies. The K2 observations yield a folded light curve with lower time resolution but with substantially better statistical precision compared with the ground-based observations. We detect a significant “bump” just after the transit egress, and a less significant bump just prior to transit ingress. We interpret these bumps in the context of a planet that is not only likely streaming a dust tail behind it, but also has a more prominent leading dust trail that precedes it. This effect is modeled in terms of dust grains that can escape to beyond the planet's Hill sphere and effectively undergo “Roche lobe overflow,” even though the planet's surface is likely underfilling its Roche lobe by a factor of 2.
