Glucose concentrations in ULF were greater in heifers with increased antral follicle numbers. Glucose ULF concentrations increased in pregnant heifers. Facilitated glucose transporter member 1 (SLC2A1) transcript abundance was increased in the endometrium of pregnant heifers but was not different due to antral follicle number or the interaction. Differences in uterine concentrations of glucose associated with antral follicle number could be due to another mechanism, since glucose transporters were not different between antral follicle numbers. Therefore, heifers with increased number of antral follicles have increased energy availability in the uterus to support trophoblast proliferation and function.

The aim of this study is to investigate the predictive value of relative surface area of hematoma on poor prognosis of spontaneous intracerebral hemorrhage (sICH).

We retrospectively analyzed 102 patients with sICH who met the inclusion criteria, attending to Yongchuan Hospital of Chongqing Medical University from January 2019 to September 2020. Cranial CT within 6h of onset was completed and repeated in 24h. The volume and surface area of the hematoma are measured by software, and the relative surface area is calculated from the above data. The primary outcome was 90-day modified Rankin Scale(mRS) score, which was classified as good prognosis (≤2 points) and poor prognosis (>2 points) according to the results. Univariate analysis and binary logistic regression analysis were used to calculate the effect of each variable on poor prognosis.

The study is comprised of 52 patients with favorable functional prognosis and 50 patients with unfavorable one. The findings showed that admission National Institutes of Health Stroke Scale(NIHSS), hematoma volume, relative surface area, hematoma expansion(HE) and serum calcium concentration were independent influencing factors for poor prognosis(P=0.004,0.007,0.023,0.001,0.035, respectively). ROC curve analysis revealed that the area under the curve of the relative surface area of the hematoma predicted poor prognosis was 0.894(95% CI 0.830-0.985, P<0.001), which was better than the rest of the variables.

The relative surface area of hematoma in sICH is an independent risk factor for poor prognosis with a high predictive value, and large relative surface area suggests poor prognosis.

So far, this rhythmic attentional sampling has predominantly been demonstrated with regards to external visual attention, directed toward one single feature dimension. Whether and how attention might sample from concurrent internal representations of different feature dimensions held in working memory (WM) is currently largely unknown. To elucidate this issue, we conducted a human behavioral dense-sampling experiment, in which participants had to hold representations of two distinct feature dimensions (color and orientation) in WM. By querying the contents of WM at 72 time-points after encoding, we estimated the activity time course of the individual feature representations. Our results demonstrate an oscillatory component at 9.4 Hz in the joint time courses of both representations, presumably reflecting a common early perceptual sampling process in the alpha-frequency range. Furthermore, we observed an oscillatory component at 3.5 Hz in the time course difference between the two representations. This likely corresponds to a later attentional sampling process and indicates that internal representations of distinct features are activated in alteration. In summary, we demonstrate the cyclic reactivation of internal WM representations of distinct feature dimensions, as well as the co-occurrence of behavioral fluctuations at distinct frequencies, presumably associated to internal perceptual- and attentional rhythms. In addition, our findings also challenge a model of strict parallel processing in visual search, thus, providing novel input to the ongoing debate on whether search for more than one target feature constitutes a parallel- or a sequential mechanism.The redox state disorder of biological system caused by oxidative stress can lead to a variety of clinical dysfunction and diseases. this website It is an important challenge to find artificial materials that can efficiently adjust the redox balance to maintain health. In this work, a nitrogen-doped carbon (NCDs) redox nanozyme loaded into metal organic framework (MOF, UiO-66) is designed to form NCDs/UiO-66 nanocomposites. The high specific surface area and porosity of UiO-66 serve as ideal carrier to support multifunctional NCDs. NCDs/UiO-66 nanocomposites are comprehensively investigated for their ability to scavenge or generate reactive oxygen species (ROS) and free radicals. Experimental results demonstrate that NCDs/UiO-66 can remove intrinsic free radicals (•OH, O2•- and ABTS•+), exhibiting superoxide dismutase-like activity and antioxidant capability. Moreover, NCDs/UiO-66 can efficiently produce ROS (•OH, O2•- and 1O2) under irradiation showing light induced oxidase-like activity and pro-oxidant capability. This suggests the anti-oxidant and pro-oxidant activities of NCDs/UiO-66 could be regulated easily by light irradiation. Using the fluorescent property and light-activated oxidase-like activity of NCDs/UiO-66, the methods for detection of ferric ion (Fe3+) and glutathione (GSH) are developed.The development of high-efficiency and cost-effective difunctional electrocatalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are highly attractive to fulfill the practical water electrolysis. Herein, a novel low-cost difunctional cobalt-nickel sulfide (Co3S4/Ni3S2) flower-like heterostructures are purposely loaded on the surface of polypyrrole (PPy) nanosheets on nickel foam (NF) via feasible and efficient electrodeposition and hydrothermal tactics. The unique hierarchical architecture of the PPy nanosheets and strong electron interaction in the Co3S4/Ni3S2 nanohybrid effectively offer sufficient specific surface area and regulate electronic configuration for expediting the electrocatalytic process. The theoretical simulations also provide convincing proof that the interface of the Co3S4/Ni3S2 heterostructures supplies a lower energy pathway for water adsorption and dissociation, and the electrons migration that occurs when heterostructures emerge is probably the root of the result above. Consequently, the as-fabricated Co3S4/Ni3S2@PPy/NF exhibits outstanding electrochemical activity of HER and OER requiring low overpotentials of 63 mV and 207 mV to reach a current density of 10 mA cm-2 in the alkaline electrolyte, respectively. When equipped in a two-electrode electrolyzer, the Co3S4/Ni3S2@PPy/NF electrode couple displays a low voltage of only 1.52 V at 10 mA cm-2, indicating its potential application in the field of the water electrolysis.Diurnal patterns of methane flux are examined at a landfill in the Southeastern US. Methane fluxes are measured by an eddy covariance (EC) tower during representative one-week periods in three seasons summer, fall, and winter. Measured methane fluxes are compared with atmospheric pressure, temporal variation of atmospheric pressure, wind shear velocity, and air temperature. Landfill methane flux varies significantly with shear velocity and temporal changes in atmospheric pressure when the atmosphere is neutral. Under unstable atmospheric conditions, air temperature correlates best with methane flux, which is corroborated with an independent dataset of tracer correlation method (TCM) measurements for similar measurement periods. These field data support a mathematical model previously proposed to describe atmospheric effects on methane flux from landfills. The field data also indicate significant diurnal methane flux variations, with daytime fluxes up to 23 times greater than nighttime fluxes. Because the majority of historical TCM measurements of whole landfill methane flux are between 12 pm and 6 pm at this landfill, when daily emissions are highest because of atmospheric effects, average diurnal fluxes might have been overestimated by as much as 73%. Methane emissions are most representative of diurnal average emissions when atmospheric stability is near-neutral, which occurs in the late morning (∼11 am) and in the early evening (∼5 pm) at this site.

This study was conducted as a randomized controlled study to evaluate the effect of self-acupressure on fatigue in patients with Multiple Sclerosis (MS).

The sample of the study consisted of 123 patients (41 in the experiment group, 40 in the sham group, and 42 controls) who were admitted to a neurology clinic in a university hospital. To collect data a patient information form, Fatigue Severity Scale (FSS), Expanded Disability Status Scale (EDSS), and Mini-Mental Status Examination were used. Depressive mood and sleep quality, which may affect fatigue, were evaluated using the Beck Depression Scale (BDI-II) and Pittsburg Sleep Quality Index (PSQI), respectively. The patients in the experimental group were applied acupressure by use of LI4 (He Gu), SP6 (San Yin Jiao) and ST36 (Zu San Li) points.

The majority of patients were female (67.5%) and the mean age was 41.18. In addition, the mean BDI-II score of the patients was found to be 15.54, and the mean score of PSQI was 6.78 and the mean scores of these scales were similar in all groups. When the baseline FSS score means were examined, there was no significant difference among the groups (Acupressure5.54±0.87, Control5.40±0.92, and Sham5.50±0.99; p=0.816). In the 4th week, there was a significant decrease in the mean score of fatigue of the experimental group compared to the other two groups (Acupressure4.15±1.09, Control5.47±1.11, Sham5.34±1.14, p<0,001).

Our results suggest that acupressure might be an effective method to reduce fatigue in patients with MS.

The causes of this plasticity, however, remain poorly understood, and comparative phylogenic analyses of such plasticity are rare. Here, we analyzed a field germination dataset including 474 species exposed to three different levels of light availability, using comparative phylogenetic methods. We calculated the plasticity of germination in response to light availability (PGGP) based on the maximum germination proportion (GPmax), PGT50 based on the time required to reach 50% of GPmax, PGRGV based on the relative germination velocity (RGV), and PGTotal based on all three of these germination traits. We found that closely related species shared similar light plasticity of germination behavior. Different aspects of germination plasticity in response to light availability were related to specific traits or local environment. PGGP was associated with adult longevity and local water habitat, while PGT50 was related to seed mass and local water habitat, and PGRGV was marginally significantly related to plant height.
