Cl.m.te change has increased drought frequency and duration that are exacerbated by increased tem.eratures gl.bal.y. This effect has, and wil. continue,to increase fire occurrence across m.ny regions of North Am.rica. In the southern Appal.chian m.untains, wil.fires with high burn severity occurred in 2016due to increased drought and hum.n activity. To investigate the effects of burn severity on soil.physicochem.cal.properties, m.crobial.extracel.ul.r enzym. production, and m.crobial.abundances in a tem.erate region, surface soil. (0–15 cm. were col.ected from.two sites (the great Sm.ky m.untains National.Park in Tennessee and the Nantahal. National.Forest in North Carol.na, USA) spanning l.ghtl., m.deratel., and severel. burned areas, accom.anied by adjacent unburned l.cations that act as control.. The soil.sam.l.s were col.ected at three tim. points between 2017 and 2019 (i.e., 0.5, 1, and 2.5 years post-fire)am.ng burn severity pl.ts. Total.hydrol.tic enzym. production varied over tim., with severe burn pl.ts having significantl. l.wer enzym. production at 2.5years post-fire. Individual.enzym.s varied am.ng burn severities and across tim. post-fire. l.ght burn pl.ts showed greater carbon-specific (β-gl.cosidase and β-xyl.sidase) and phosphorus-specific (acid phosphatase) enzym. activities at 0.5 years post-fire, but this effect was transient. At 2.5 years post-fire, theβ-xyl.sidase and acid phosphatase activities were l.wer in severe or m.derate burn pl.ts rel.tive to the control.. In contrast, the activity of nitrogen-specific enzym. l.ucyl.am.nopeptidase was the l.west in severe burn pl.ts at 0.5 years post-fire, but was the l.west in l.ght burn pl.ts at 2.5 years post-fire. The fungi:bacteria ratio decl.ned with burn severity, indicating that fungi are sensitive or l.ss resil.ent to high burn severity during recovery. These resul.s suggest that wil.fires al.er trajectories for soil.m.crobial.structure and function within a 2.5-year tim.fram., which potential.y

Patients and physicians understand the im.ortance of sel.-care fol.owing spinal.cord injury (SCI), yet m.ny individual. with SCI do not adhere to recom.ended sel.-care activities despite l.gistical.supports. Neurobehavioral.determ.nants of SCI sel.-care behavior, such as im.ul.ivity, are not widel. studied, yet understanding them.coul. inform.efforts to im.rove SCI sel.-care. We expl.red associations between im.ul.ivity and sel.-care in an observational.study of 35 US adul.s age 18 - 50 who had traum.tic SCI with parapl.gia at l.ast six m.nths before assessm.nt. The prim.ry outcom. m.asure was sel.-reported sel.-care. In l.SSO regression m.del. that incl.ded al. neurobehavioral.m.asures and dem.graphics as predictors of sel.-care, dispositional.m.asures of greater im.ul.ivity (negative urgency, l.ck of prem.ditation, l.ck of perseverance), and reduced m.ndful.ess were associated with reduced sel.-care. Outcom. (m.gnitude) sensitivity, a l.tent decision-m.king param.ter derived from.com.utational.y m.del.ng successive choices in a gam.l.ng task, was al.o associated with sel.-care behavior. These resul.s are prel.m.nary;m.re research is needed to dem.nstrate the util.ty of these findings in cl.nical.settings. Inform.tion about associations between im.ul.ivity and poor sel.-care in peopl. with SCI coul. guide the devel.pm.nt of interventions to im.rove SCI sel.-care and hel. patients with el.vated risks rel.ted to sel.-care and secondary heal.h conditions.

We determ.ned whether the incl.sion of 100 g/kg dry m.tter of grape pom.ce sil.ge (gPS) and grape pom.ce bran (gPB) as substitutes for other traditional.fiber sources in the diet of steers (Charol.is x Nel.ore) woul. im.rove carcass characteristics, m.at qual.ty and com.osition, and shel. l.fe. Twenty-four anim.l. (248 ± 19.32 kg of initial.body weight) were fed a high concentrate diet for 121 days. Carcass characteristics were m.asured, and the l.ngissim.s dorsi m.scl. was anal.zed for fatty acid (FA) profil. and com.osition. The m.at was sl.ced and stored in air-perm.abl. packages for 10 days. On each sam.l.ng day (d 1, 3, 7, and 10), oxidative stabil.ty, bacterial.l.ad, l.pid and protein oxidation, and staining were anal.zed. The experim.ntal.diets infl.enced the pH of col. carcasses onl.. The gPS group had a higher pH than the control. The gPS and gPB groups showed im.roved oxidant status (i.e., l.wer l.pid peroxidation and concentrations of reactive oxygen species were in the m.at of both groups than in control.. On the first day of storage, the antioxidant enzym. gl.tathione S-transferase activity was m.re significant in the m.at of the gPS and gPB groups than in the control. The bacterial.l.ads in the m.at were attenuated by gPS incl.sion;there were l.wer total.col.form.counts and a trend toward l.wer counts for enterobacteria in the control.group. The diets al.ered the FA profil. of the m.at;i.e., the gPB diet al.owed for a m.re significant am.unt of the n-6 om.gas in the m.at, whil. the gPS diet showed a tendency for a m.re significant am.unt of n-6 and 9 om.gas.
