    Notes: Abstract The authors report 17 cases of a right non-recurrent inferior laryngeal n. (NRILN) observed during 15 years of practice of thyroid and parathyroid surgery. In their last two cases, the existence of an aberrant right subclavian a., constantly associated with NRILN, was confirmed by MRI angiography. On the basis of the literature and their own experience, the authors review the incidence of this double anomaly, its embryologic explanation and its anatomic and surgical importance. They stress the diagnostic factors and the therapeutic implications, very different in children and adults, of a particular vascular anomaly whose outcome is little understood.

    Description / Table of Contents: Résumé Les auteurs rapportent 17 cas de non recurrence du nerf laryngé inferieur droit, observés en 15 ans de pratique de la chirurgie thyroidienne et parathyroidienne. Dans les deux dernières observations, l'existence d'une artère subclavière droite aberrante — ou arteria lusoria, constamment associée à l'anomalie nerveuse, a pu être confirmée par une angioIRM. S'appuyant sur la revue de la littérature et sur leur expérience personnelle, les auteurs rappellent la fréquence de cette double anomalie, son explication embryologique et son interêt anatomique et chirurgical. Ils insistent sur les circonstances diagnostiques et les conséquences thérapeutiques, très différentes chez l'enfant et chez l'adulte, d'une anomalie notamment vasculaire dont on connait mal les complications évolutives.

    Description / Table of Contents: Résumé Les auteurs ont étudié les modifications morphologiques de l'a. poplitée lors de la flexion du genou. L'étude radio-anatomique comporte l'analyse d'artériographies de profil pour différents degrés de flexion articulaire, puis des dissections pour objectiver les structures anatomiques en cause dans l'adaptation morphologique de l'a. poplitée au mouvement articulaire. Chez 5 sujets volontaires, non athéromateux, 15 séquences angiographiques en I.R.M. ont été réalisées au niveau des genoux en position d'extension et de flexion. Les artériographies et l'angio-I.R.M. montrent qu'au fur et à mesure que le degré de flexion articulaire augmente, des flexuosités apparaissent au niveau de l'a. poplitée haute supra-articulaire alors que les parties moyenne et basse de l'a. poplitée gardent une courbure harmonieuse, s'écartant du plan postérieur de l'articulation. Les dissections semblent montrer que cette adaptation artérielle se fait entre deux points fixes, l'un proximal : le canal des adducteurs, l'autre distal : l'origine de l'a. tibiale antérieure. L'angio-I.R.M. paraît une voie d'avenir dans l'exploration des vaisseaux des membres. L'opposition comportementale des différents segments de l'a. poplitée permet de mieux comprendre la physiopathologie des traumatismes et des malpositions de l'axe artériel poplité.
    Notes: Summary We studied the morphological modifications of the popliteal artery during knee flexion. An anatomical, radiological study consisted of analysis of lateral arteriographs in different degrees in joint flexion followed by dissection to reveal the anatomical structures involved in the morphological adaptation of the popliteal artery to joint movement. In five non-atheromatous volunteers, 15 MRI angiographic sequences were done at the level of the knee in extension and flexion. The arteriographs and angio MRI showed that as joint flexion increased tortuosities appeared in the supra-articular upper popliteal artery while the middle and lower parts of the popliteal artery kept an even curve retracted from the posteriror surface of the joint. Dissection seemed to show that this arterial adaptation occurred between two fixed points, one proximal (the adductor canal) and the other distal (the origin of the anterior tibial artery). Angio MRI seems to be a future route for the assessment of the limb vessels. The contrasting behaviour of the different segments of the popliteal artery allows us to understand better the pathophysiology of trauma and malpositions of the popliteal arterial trunk.

    Notes: Abstract. High-quality single-walled carbon nanotubes (SWNTs) are synthesized by chemical vapor deposition (CVD) of methane on silicon-dioxide substrates at controlled locations using patterned catalytic islands. With the synthesized nanotube chips, microfabrication techniques are used to reliably contact individual SWNTs and obtain low contact resistance. The combined chemical synthesis and microfabrication approaches enable systematic characterization of electron transport properties of a large number of individual SWNTs. Results of electrical properties of representative semiconducting and metallic SWNTs are presented. The lowest two-terminal resistance for individual metallic SWNTs (≈5 μm long) is ≈16.5 kΩ measured at 4.2 K.

    Notes: Summary The excretion of noscapine in human breast milk was studied in 8 lactating women given a single oral dose of 100 or 150 mg after a light breakfast. Serum and milk samples were collected for 24 h after drug intake. Although noscapine is a weak base, only a small amount was excreted in the milk. The median milk/serum ratio was 0.29, range 0.15–0.88. The noscapine dose received by a child during a 24 hour period, when the maternal dose is 50 mg t.i.d., was calculated to be 0.8 (0.4–1.9) µg/kg (median and range).

    Notes: A biological procedure was devised to evaluate de Ruyter and Brunet's heat transfer computer simulation for sterilizing particulate foods in a swept surface heat exchanger (SSHE). Turkey cubes measuring 12.7 mm were inoculated with spores of Clostridium sporogenes PA3679, using a so-called “knotted string” method. Inoculated cubes were introduced into a viscous starch medium and thermally processed in a SSHE to a fractional survivor endpoint. Processed product was packaged aseptically, incubated and examined for survivors. Biological sterilization values calculated from the inoculated packs support the validity of the simulation. Also, a novel method was devised to measure particle residence times in hold tubes using electro-magnetic induction.
