Compression of the ulnar nerve by the arcade of Struthers: Look and you shall find
No full textBACKGROUND: The arcade of Struthers was first proposed by Kane et al in 1973. Clinical investigations of this structure have been limited to small case series, focusing on the arcade as an isolated cause of compressive ulnar neuropathy. The purpose of our study was to investigate the incidence of this structure in patients undergoing ulnar nerve transposition.
METHODS: A retrospective chart review of prospectively maintained data in a single surgeon\u27s practice was performed. Records of patients undergoing surgery for compressive ulnar neuropathy at the cubital tunnel were evaluated for documentation of a compressive arcade of Struthers. In addition, a scoping review of the literature was undertaken to better characterize current understanding of this structure and its recognition in clinical practice.
RESULTS: A total of 197 patients underwent ulnar nerve transposition. The overall incidence of a compressive arcade of Struthers was noted to be 67 out of 197 (34%). All patients with a compressive arcade were noted to have an internal brachial ligament running below the nerve. Patients undergoing revision surgery were found to have a compressive arcade 51% of the time (20/39), whereas 30% of patients undergoing primary surgery were found to have a compressive arcade (47/158). Only 12 clinical studies examining the arcade of Struthers have been published in the last 20 years, the majority being single case reports.
CONCLUSIONS: Compression of the ulnar nerve by the arcade of Struthers is a common finding and can contribute to compressive ulnar neuropathy at the elbow both in primary and revision cases

It is conceivable that specimens reported by Parin and Kotlyar (1989: 412, fig. 3; as <i>H. japonica</i>) from the central Coral Sea (ZIL 47258, 2: 232–248 mm SL, 23° 04' N, 159° 37' E, 320 m; ZIL 47260, 213 mm SL, 25° 35' N, 159° 23' E, 330 m) are this species, but they are more likely to be <i>H. pyrhistion</i>, as are those reported by Gomon <i>et al</i>.

It is closest to <i>H. surrubea</i> in head and eye size (orbital diameter 30.1–33.3, mean 31.8 and 10.1–11.8, mean 10.9% SL respectively in the latter) and to a lesser extent <i>H. caudizoma</i> for the same features (30.5–32.6, mean 31.7 and 9.7–11.4, mean 10.8% SL in the latter). Females seem to have slightly larger heads and eyes than males of these and most other species of the genus. Proportionally, <i>H. capitonis, H. surrubea</i> and females of <i>H. caudizoma</i> have the largest eyes relative to the size of the head for the genus (33.5–38.7, mean 36.4, 31.2–38.1, mean 34.3, and 30.6–36.2, mean 33.9, respectively, versus 22.5–36.0, mean 29.9% HL in other congeners). <i>Hime capitonis</i> has rather large pelvic fins, similar to those of males of <i>H. japonica</i> (length in males 24.3–29.6, mean 27.2, and 25.9–30.3, mean 27.7% SL, respectively), but unlike that species, pelvic fins of both sexes in the former are of similar sizes. <i>Hime caudizoma</i>, <i>H. diactithrix</i> and <i>H. curtirostris</i> also have large pelvic fins in one or both sexes, fins of large males of the last species approaching the origin of the anal fin.</p> <p> This species has appeared in the literature, misidentified as <i>H. japonica,</i> only as components of faunal or catch composition lists as presented in the above synonymy.</p> <p> <i>Hime caudizoma</i> sp. nov.</p> <p>English vernacular name: Indonesian Flagfin Indonesian vernacular name: Kuniran Merah Figs 1, 3, 5; Tbls 1–3</p> <p> <i>Hime</i> sp.

Modelling the water balance of a free-draining lysimeter using the downward approach
No full textA 2600 m(3) free-draining lysimeter constructed in a Pinus sylvestris plantation forest in Colbitz, Germany, has been monitored daily since 1974, with the intent of improving the understanding the effect of afforestation upon groundwater recharge (drainage). The objective of this research was to employ a downward approach in the development of a conceptual water balance model applicable to the site. Observed annual and inter-annual trends were successfully replicated by a simple capacitance model using a simplified representation of vegetation growth. An important limitation of the capacitance approach in simulating the timing of drainage at sub-annual time scales was identified, which could not be overcome by adding complexity to the model basis. Given the a priori use of capacitance approaches for simulating drainage in many hydrological models, the findings of this study suggest that (a) these approaches are sufficient where the prediction of annual and inter-annual drainage behaviour is the primary objective, and that (b) an alternative basis accounting for the time delay between precipitation inputs and drainage generation is required for modelling if the prediction of drainage at sub-annual time scales is a priority.

No full textThe role of urate and xanthine oxidase in vascular oxidative stress:Future directions
No full textVascular oxidative stress has been shown to be a potent factor in the pathophysiology of endothelial dysfunction. Despite current optimal evidence-based therapy, mortality from various cardiovascular disorders remains high. The search for newer, novel ways of attenuating endothelial dysfunction has yielded several new and exciting possibilities, one of which is the manipulation of urate levels using xanthine oxidase inhibitors. Agents such as allopurinol have shown marked improvements in vascular endothelial function in various cohorts at risk of cardiovascular events. Most of the evidence so far comes from smaller mechanistic studies. The few large randomized controlled trials have failed to show any significant mortality benefit using these agents. This article highlights the potential avenues of further research such as dose-response, and the potential for these agents to regress left ventricular hypertrophy. The role of newer agents such as febuxostat and oxypurinol are discussed as well as potential reasons why some of the current newer agents have failed to live up to the promising early-phase data. It is crucial that these remaining questions surrounding urate, xanthine oxidase and the role of various agents that affect this important oxidative stress-generating system are answered, and therefore these promising agents should not be discarded prematurely
