Increase of Poison-Bitterweed (Hymenoxys odorata) on Texas Range Lands

This paper, as read before the Texas Academy of Science, was titled Increase of Native Weedy Forbs on Texas Range Lands. The reason for the change of title here is that, from a range standpoint, not all forbs are weeds and not all weeds are forbs. Forbs are herbaceous plants that are not grasses or grass-like plants. Some of the forbs are toxic to livestock or so unpalatable to them they feed upon them only when excessively hungry or starving. In reality some of these range forbs are forage plants and some are not

Dehydration, Muscle Damage, and Exercise in the Heat: Impacts on Renal Stress, Thermoregulation, and Muscular Damage Recovery

Purpose: The purpose was to identify the combined influence of dehydration, muscle damage, and exertional hyperthermia on biological markers of acute kidney injury and renal function. We also investigated the effects of performing muscle damaging exercise during mild hypohydration on muscle damage biomarkers and muscular strength recovery. Methods: Eighteen recreationally-active males (age 24 ± 5 y, body fat 17.3 ± 6.2%) completed a familiarization visit and two experimental trials separated by ≥28 days. The two experimental conditions consisted of either euhydration (EU; maintaining hydration, -1.2 ± 0.8%) or hypohydration (HY; restricting fluid consumption for 24 hours prior to and during the trial, -4.4 ± 1.9%). Participants completed a unilateral eccentric knee flexion muscle damaging protocol, 60-minute treadmill exercise in the heat, 30-minute passive recovery, and a rehydrated 24-h follow-up visit, respectively. Results: Strength was reduced across time independent of trial for isometric strength at 70° (P\u3c0.001), isometric strength at 90° (P=0.001), and isokinetic strength at 60°·sec-1 (P=0.001). Serum creatine kinase increased regardless of trial (P\u3c0.001), with the 24-h follow-up greater (grand mean; 58.7 ± 25.1 U/L) than at baseline (grand mean; 35.7 ± 23.1 U/L, P\u3c0.001) and post-exercise (grand mean; 51.6 ± 23.2 U/L, P=0.009). Percent change in plasma neutrophil gelatinous associated lipocalin was greater in the HY trial post-exercise (EU 28.0 ± 15.2%, HY 41.8 ± 17.5%, P\u3c0.001), but not at 24-h follow-up (P=0.39). Serum creatinine was increased in the HY trial regardless of time (EU 0.97 ± 0.14, HY 1.04 ± 0.15, mg/dL, P=0.025). Urine NGAL and urine creatinine were also elevated in the HY trial pre-exercise and post-exercise (all, P\u3c0.05) but were returned to EU levels by 24-h follow-up (all, P\u3e0.05). Conclusions: We demonstrated no significant impact of hydration status when performing muscle damaging exercise, followed by exercise in the heat, on indices of muscle damage recovery. Exercise in the heat with muscle damage increased physiological and renal strain when HY, but the rehydration protocol ameliorated differences between trials by the 24-h follow-up. These findings highlight the importance of proper fluid intake following exercise to mitigate renal stress
