BACKGROUND Hyaluronan (HA) is the dominant glycosaminoglycan in the renomedullary interstitium. Renomedullary HA has been implicated in tubular fluid handling due to its water-attracting properties and the changes occurring in parallel to acute variations in the body hydration status. METHODS HA production was inhibited by 4-methylumbelliferone (4-MU in drinking water for 5 days, 1.45 ± 0.07 ...

Angular distributions of the 14–17 MeV g rays from the Li~p ,g) reaction at Ep5450, 402, and 80 keV were measured at 0°<u lab<135°, using a BGO detector and a 28-mg/cm 2 LiF target. The angular distributions at Ep5450 and 402 keV agree with the previous results by Mainsbridge; at Ep580 keV the ground-state transition is anisotropic on the order of 20%, confirming recent results by Chasteler et al.

Background: DNA repair mechanisms are crucial for sustaining DNA integrity and preventing carcinogenesis. The xeroderma pigmentosum group G (XPG), X-ray repair cross complementing group 2 (XRCC2) and RAD51 are candidate genes for DNA repair pathways. Methods: We performed a meta-analysis of 26 studies that assessed the impact of XPG Asp1104His, XRCC2 rs3218536 A/G and RAD51 135G/C polymorphisms...

We prove that the set of long cycles has the edge-Erdős-Pósa property: for every fixed integer ` ≥ 3 and every k ∈ N, every graph G either contains k edge-disjoint cycles of length at least ` (long cycles) or an edge set X of size O(k log k + `k) such that G−X does not contain any long cycle. This answers a question of Birmelé, Bondy, and Reed (Combinatorica 27 (2007), 135–145).

The body weight and testicular and epididymal parameters of Afar, Long-eared Somali (LES), and Woyto-Guji (WG) breeds of goat were investigated. A total of 405 randomly selected bucks of Afar (n = 135), Long-eared Somali (n = 135), and Woyto-Guji (n = 135) were included in this study. The overall mean scrotal circumference (SC), testicular volume (TV), testicular length (TL), testicular weight ...
