The A. S. Mann (41HE7/41AN201) and M. S. Roberts (41HE8) Sites in the Upper Neches River Basin, Henderson County, Texas

The upper Neches River basin in East Texas has been the scene of archaeological research since the early 1900s, with a particular focus on the post-A.D. 1000 archaeological record of the Caddo peoples in the region. The A. S. Mann (41HE7) and M. S. Roberts (41HE8) sites are ancestral Caddo sites located in the modern-day Pineywoods that were investigated by University of Texas (UT) archaeologists in the 1930s. I want to thank Waldo Troell for bringing these sites to my attention

Joint management of marine mammals and a fish species : The case of cod and grey seals in the Nordic-Baltic Sea countries

In this paper, we present a simple theoretical, steady-state equilibrium, predator-prey model for the joint management of marine mammals and a fish species. As an empirical case, we choose cod and grey seals in the Nordic-Baltic Sea countries, and several benefits and costs related to the latter are considered. We show that the optimal grey seal population is much lower than the actual population, and this result is robust to variations in relevant parameter values. This result can be explained by the fact that the profit from harvesting cod is much higher than the net benefits from grey seals.Peer reviewe

Product costing and activity-based costing/management in Bacalhôa Vinhos de Portugal

The present Work Project introduces a case study addressing the adoption of an ABC/M system in a winemaking company. The system was implemented in only one area of the company, and its adoption allows the company to perform ABM analysis resorting to the ABC information. A mixed approach is used to cost the products: both traditional and ABC systems are used although in different areas of the company. ABC/M implementation was perceived as ‘successful’ despite not following recommendations prescribed in literature

Urinary Epidermal Growth Factor as a Marker of Disease Progression in Children With Nephrotic Syndrome

© 2019 International Society of Nephrology Introduction: Childhood-onset nephrotic syndrome has a variable clinical course. Improved predictive markers of long-term outcomes in children with nephrotic syndrome are needed. This study tests the association between baseline urinary epidermal growth factor (uEGF) excretion and longitudinal kidney function in children with nephrotic syndrome. Methods: The study evaluated 191 participants younger than 18 years enrolled in the Nephrotic Syndrome Study Network, including 118 with their first clinically indicated kidney biopsy (68 minimal change disease; 50 focal seNorthwell Healthntal glomerulosclerosis) and 73 with incident nephrotic syndrome without a biopsy. uEGF was measured at baseline for all participants and normalized by the urine creatinine (Cr) concentration. Renal epidermal growth factor (EGF) mRNA was measured in the tubular compartment microdissected from kidney biopsy cores from a subset of patients. Linear mixed models were used to test if baseline uEGF/Cr and EGF mRNA expression were associated with change in estimated glomerular filtration rate (eGFR) over time. Results: Higher uEGF/Cr at baseline was associated with slower eGFR decline during follow-up (median follow-up = 30 months). Halving of uEGF/Cr was associated with a decrease in eGFR slope of 2.0 ml/min per 1.73 m2 per year (P \u3c 0.001) adjusted for age, race, diagnosis, baseline eGFR and proteinuria, and APOL1 genotype. In the biopsied subgroup, uEGF/Cr was correlated with EGF mRNA expression (r = 0.74; P \u3c 0.001), but uEGF/Cr was retained over mRNA expression as the stronger predictor of eGFR slope after multivariable adjustment (decrease in eGFR slope of 1.7 ml/min per 1.73 m2 per year per log2 decrease in uEGF/Cr; P \u3c 0.001). Conclusion: uEGF/Cr may be a useful noninvasive biomarker that can assist in predicting the long-term course of kidney function in children with incident nephrotic syndrome

Agonist-induced alteration in the membrane form of muscarinic cholinergic receptors

Incubation of 1321N1 human astrocytoma cells with carbachol resulted in a rapid loss of binding of [3H]N-methylscopolamine ([3H]NMS) to muscarinic cholinergic receptors measured at 4 degrees C on intact cells; loss of muscarinic receptors in lysates from the same cells measured with [3H]quinuclidinyl benzilate [( 3H]QNB) at 37 degrees C occurred at a slower rate. Upon removal of agonist from the medium, the lost [3H]NMS binding sites measured on intact cells recovered with a t1/2 of approximately 20 min, but only to the level to which [3H]QNB binding sites had been lost; no recovery of "lost" [3H]QNB binding sites occurred over the same period. Based on these data and the arguments of Galper et al. (Galper, J. B., Dziekan, L. C., O'Hara, D. S., and Smith, T. W. (1982) J. Biol. Chem. 257, 10344-10356) regarding the relative hydrophilicity of [3H]NMS versus [3H]QNB, it is proposed that carbachol induces a rapid sequestration of muscarinic receptors that is followed by a loss of these receptors from the cell. These carbachol-induced changes are accompanied by a change in the membrane form of the muscarinic receptor. Although essentially all of the muscarinic receptors from control cells co-purified with the plasma membrane fraction on sucrose density gradients, 20-35% of the muscarinic receptors from cells treated for 30 min with 100 microM carbachol migrated to a much lower sucrose density. This conversion of muscarinic receptors to a "light vesicle" form occurred with a t1/2 approximately 10 min, and reversed with a t1/2 approximately 20 min. In contrast to previous results in this cell line regarding beta-adrenergic receptors (Harden, T. K., Cotton, C. U., Waldo, G. L., Lutton, J. K., and Perkins, J. P. (1980) Science 210, 441-443), agonist binding to muscarinic receptors in the light vesicle fraction obtained from carbachol-treated cells was still regulated by GTP. One interpretation of these data is that agonists induce an internalization of muscarinic receptors with the retention of their functional interaction with a guanine nucleotide regulatory protein
