Detecting intestinal ischemia using near infrared spectroscopy
No full textBlood supply to the intestine can suddenly be interrupted. Acute mesenteric intestinal ischemia often requires invasive surgery to restore blood supply to the intestine. Early correction of vascular insufficiency is the most important factor in improving patient survival when confronted with acute mesenteric intestinal ischemia. A prolonged loss of blood flow results in irreversible damage to the intestine that can lead to death. It is also imperative that dead segments of the intestines be removed. Several subjective criteria are relied upon to differentiate viable from non-viable tissue, unfortunately, these criteria can lead to an inaccurate assessment. A porcine model of intestinal ischemia was used to determine the efficacy of using near infrared (NIR) spectroscopy to find ischemic segments of the intestine and detect the onset of reperfusion following resolution of vascular occlusion. Nine segments of intestine were identified and six were assigned to three treatment groups; (1) segments undergoing no vascular manipulations, (2) segments undergoing arterial/venous occlusion and (3) segments undergoing arterial/venous occlusion followed by reperfusion. The remaining segments were used as spacers and interposed between each of the ischemia segments. A classification model, using partial least square discriminant analysis, was built on the spectra collected from the segments with no vascular manipulations and the segments that were solely subjected to arterial/venous occlusion. The spectra collected from the intestinal segments that experienced both occlusion and reperfusion were used to test the classification model. The model was able to detect and distinguish ischemic intestinal tissue with a specificity and sensitivity exceeding 80% with an overall classification accuracy of 89%. The method appears to be well suited as an intra-operative assessment method when intestinal ischemia is a concern.Michael G. Sowa, Elicia Kohlenberg, Jeri R. Payette, Lorenzo Leonardi, Michelle A.

The cephalic region lacks a distinct labial disc, and has six labial sectors of equal width, amalgamated, separated by pairs of well­developed ribs.</p> <p> <i>Relationships</i></p> <p> The genus <i>Laimaphelenchus</i> contains two groups of species, one with a vulval flap and one without (Baujard 1981; Hunt 1993). <i>Lamaphelenchus australis</i> <b>sp. nov.</b> belongs to the second group, bringing its members to five. The other species in this group are <i>L. pannocaudus</i> Massey, <i>L. phloesini</i> Massey, <i>L. pini</i> Baujard, and <i>L. patulus</i> Swart. <i>Laimaphelenchus australis</i> <b>sp. nov.</b> is separated from <i>L. penardi</i> Steiner, <i>L. deconincki</i> Elmiligy and Geraert, <i>L. pensobrinus</i> Massey, <i>L. cocuccii</i> Doucet, <i>L. unituberculus</i> Bajaj and Walia, <i>L. helicosoma</i> Peneva and Chipev, and <i>L. preissii</i> Zhao, Davies, Riley and Nobbs by the absence of a vulval flap in the former.</p> <p> Females of <i>L. australis</i> <b>sp. nov.</b> (371.5–459.2 µm) are close to <i>L. pini</i> (350–470 µm) (Baujard 1981), <i>L. patulus</i> (460–530 µm) (Swart 1997) and <i>L. phloeosini</i> (430–510 µm) (Massey 1974) in body length. They are shorter than all other described species; <i>L. penardi</i> (573–800 µm) (Filipipjev and Schuurmans Stekhoven 1941), <i>L. deconincki</i> (690–770 µm) (Elmiligy and Geraert 1972), <i>L. pensobrinus</i> (610 µm) (Massey 1966); <i>L. pannocaudus</i> (960 µm) (Massey 1966); <i>L. cocuccii</i> (570–740 µm) (Doucet 1992); <i>L. unituberculus</i> (690–800 µm) (Bajaj and Walia 2000), <i>L. helicosoma</i> (619 µm) (Peneva and Chipev 1999), and <i>L. preissii</i> (1007–1385 µm) (Zhao <i>et al.</i> 2006).</p> <p> The length of the post­uterine sac of <i>L. australis</i> <b>sp. nov.</b> (20–52 µm) (Swart 1997) overlaps that of <i>L. phloeosini</i> (28–50 µm) (Elmiligy and Geraert 1972), <i>L. pini</i> (18–30 µm) (Baujard 1981), <i>L. patulus</i> (25–40 µm) (Swart 1997), <i>L. deconincki</i> (32–46 µm) (Elmiligy and Geraert 1972), <i>L. cocuccii</i> (40–63 µm) (Doucet 1992), <i>L. unituberculus</i> (45–60 µm) (Bajaj and Walia 2000), <i>L. pensobrinus</i> (37–44 µm) (Massey 1966) and <i>L. helicosoma</i> (21 µm) (Peneva and Chipev 1999); but is shorter than that of <i>L. pannocaudus</i> (82–103 µm) (Massey 1966), <i>L. penardi</i> (72–173 µm) (Filipipjev and Schuurmans Stekhoven 1941) and <i>L. preissii</i> (86–157 µm) (Zhao <i>et al.</i> 2006).</p> <p> The vagina is surrounded by a relatively thin cuticularised tube, which is similar to most species in the genus, but it differs from <i>L. deconincki</i> which has a thick cuticularised tube (Elmiligy and Geraert 1972).</p> <p> With respect to the lateral field, <i>L. australis</i> <b>sp. nov.</b> has 4 incisures as do <i>L. pannocaudus, L. unituberculus L. pini, L. preissiii</i> and <i>L. phloeosini</i>. It differs from <i>L. penardi</i> and <i>P. pensobrinus</i> that have 2 incisures and <i>L. patulus, L. helicosoma, L. cocuccii, L. deconincki</i> with 3.</p> <p> In general, the morphology of the tail tip of <i>L. australis</i> <b>sp. nov.</b> is similar to all described species of the genus, except <i>L. helicosoma</i> which has poorly developed tubercles (Peneva and Chipev 1999), <i>L. unituberculus</i> which has a single stalked suckerlike tubercle (Bajaj and Walia 2000), and <i>L. preissii</i> which has a broad tubercle with many tiny projections (Zhao <i>et al.</i> 2006).</p> <p> In <i>L. australis</i> <b>sp. nov.</b>, the labial disc is reduced and amalgamated with the head capsule, the anterior lip is smooth, and the oral aperture is flattened. Its cephalic region has six labial sectors of equal width, which are amalgamated but separated by pairs of welldeveloped ribs. In this, it differs from all species in the genus except that of <i>L. cocuccii</i> (Doucet 1992). However, <i>L. australis</i> <b>sp. nov.</b> can be differentiated from <i>L. cocuccii</i> by the absence of the vulval flap.</p> <p> In addition to the differences in the anterior lip between <i>L. australis</i> <b>sp. nov.</b> and <i>L. pini</i>, they also can be differentiated by the position of the oesophago­intestinal junction. In <i>L. pini,</i> the oesophago­intestinal junction is immediately posterior to the base of the bulb (Baujard 1981) but in <i>L. australis</i> <b>sp. nov.</b>, it is 1–1.5 body widths behind the bulb.</p> <p> Males of <i>L. australis</i> <b>sp. nov.</b> (300.8–411.5 µm) are shorter than the female in body length. The spicule shape is similar to that of <i>L. patulus</i>, but it differs in that no gubernaculum­like structure is present at the distal end of spicules (Swart 1997). Three pairs of subventral caudal papillae are present; one pair preanal, a second pair subventral at about 40–45% of the distance from the cloaca to the tail tip, and a third pair at about 75–80% of the distance from the cloaca to the tail terminal. This is similar to all species in the genus in terms of the number of the papillae except <i>L. pensobrinus</i> and <i>L. preissii</i> that have 2 pairs of caudal papillae (Massey 1966; Zhao <i>et al.</i> 2006) and <i>L. cocuccii</i> where males are unknown (Doucet 1992). The male of <i>L. preissii</i> also has a bursa, lacking in <i>L. australis</i> <b>sp. nov.</b> The labial plate and the tail shape are the same as in the female.</p> <p> <i>Etymology</i></p> <p>Named for Australia, the country where it was first isolated.</p>Published as part of <i>Zhao, Zeng Q., Davies, Kerrie A., Riley, Ian T. & Nobbs, Jackie M., 2006, Laimaphelenchus australis sp. nov.

Differential Acquisition of m-Sequences using Recursive Soft Sequential Estimation
No full textIn this contribution a novel sequential estimation method is proposed for the acquisition of -sequences. This sequential estimation method exploits the principle of iterative soft-in-soft-out (SISO) decoding for enhancing the acquisition performance, and that of differential pre-processing for the sake of achieving an enhanced acquisition performance, when communicating over various communication environments. Hence the advocated acquisition arrangement is referred to as the Differential Recursive Soft Sequential Estimation (DRSSE) acquisition scheme. The DRSSE acquisition scheme exhibits a low complexity, which is similar to that of an -sequence generator, while achieving an acquisition time that is linearly dependent on the number of stages in the -sequence generator. A low acquisition time is achieved with the advent of the property that the proposed DRSSE scheme is capable of determining the real-time reliabilities associated with the decision concerning a set of, say , consecutive chips. This set of consecutive chips constitutes the sufficient initial condition for enabling the local -sequence generator to produce a synchronized local despreading -sequence replica. Owing to these attractive characteristics, the DRSSE acquisition scheme constitutes a promising initial synchronization scheme for acquisition of long -sequences, when communicating over various propagation environments
