Effects of body condition score (BCS) at far-off dry period on blood biochemistry, liver triacylglycerol, and muscular monocarboxylate transporter-1 mRNA expression in tropical Holstein dairy cows during peripartum period were studied. Eight dry cows were divided into two groups of four cows based on their BCS at 8 weeks prepartum high BCS (HBS) and low BCS (LBS). Blood samples were collected weekly from 8 weeks before expected calving date until 8 weeks postpartum for determination of serum glucose, non-esterified fatty acid (NEFA), and β-hydroxybutyrate (BHBA). Muscle and liver samples were biopsied at 2 weeks before expected calving date and at 2 weeks postpartum for determination of muscular monocarboxylate transporter-1 (MCT-1) mRNA expression and liver triacylglycerol concentrations. click here Decreased BCS and elevated serum NEFA and BHBA indicated that LBS cows entered to the NEB period earlier than did HBS cows. LBS cows showed lower liver TAG and higher muscular MCT-1 mRNA expression than did HBS cows. The MCT-1 mRNA expression at 2 weeks prepartum was negatively correlated with BCSs at 2-3 weeks prepartum and at 1-2 weeks postpartum. In conclusion, LBS cows most likely adapted to NEB by upregulation of muscular MCT-1 expression and had lower NEB consequences during postpartum period.Non-precious-metal (NPM) catalysts often face the formidable challenge of a trade-off between long-term stability and high activity, which has not yet been widely addressed. Herein we propose a distinct molecule-selective fence as a promising concept to solve this activity-stability trade-off. The fence encloses the catalyst and prevents species poisonous to the catalyst from reaching it, but allows catalytic reaction-related species to diffuse freely. We constructed a CoS2 fence layer on the external surface of highly active cobalt-doped MoS2 , achieving a remarkable catalytic stability towards the alkaline hydrogen evolution reaction and improved activity. In situ spectroscopy uncovered the underlying molecular mechanism of the CoS2 fence for breaking the activity-stability trade-off of the MoS2 catalyst. This work offers valuable guidance for rationally designing efficient and stable NPM catalysts.The fine structure in the spectral lines of the visible fluorescence of Tb3+ complexes are replaced by a single peak in the case of a singular molecular complex Tb(H3 PTC)3 , where H4 PTC represents perylene-3,4,9,10-tetracarboxylic acid, and its emission wavelength depends on the film thickness. This single peak challenges the old creed that the f-orbital electrons of Tb3+ are always protected from the influence of the surrounding atoms. We perform density functional theory calculations to show that the wavefunction of the ground state is localized and in addition, spin-polarized, and this facilitates fluorescent transitions under UV to the first excited state instead of the fundamental state. We discuss the possibility of making a spintronic device with the molecule, Tb(H3 PTC)3 .Utilization of CO2 is a requirement for a sustainable production of carbon-based chemicals. The reverse water-gas-shift (RWGS) can valorize CO2 by reaction with hydrogen to produce a synthesis gas compatible with existing industrial infrastructure. Fully electrified reverse water-gas-shift (eRWGS™) was achieved using integrated ohmic heating and a nickel-type catalyst at industrially relevant conditions. Using a feed of H2   CO2 in a ratio of 2.25 at 10 barg, utilizing high temperature operation at 1050 °C allowed for production of a synthesis gas with a H2 /CO ratio of 2.0 and no detectable methane, ideal for production of sustainable fuel by e.g. the Fischer-Tropsch synthesis. Facilitating RWGS through CH4 as intermediate was found superior to the selective RWGS route, due to higher activity and suppression of carbon formation. The eRWGS™ catalyst is found to provide a preferential emissions-free route for production of synthesis gas for any relevant H2 /CO ratio, enabling production of sustainable carbon-based chemicals from CO2 and renewable electricity with high hydrogen and carbon efficiency.

Chemotherapy regimens containing glucocorticoids and pegaspargase are associated with hyperglycemia; however, the pattern and underlying risk factors are not well characterized. We determined the pattern of hyperglycemia and associated factors in children with acute lymphoblastic leukemia (ALL) receiving glucocorticoids and pegaspargase during induction.

Retrospective analysis of patients treated between 2010 and 2020 at a single institution. Pretreatment data, glucose values, and insulin regimens were abstracted from the record. Hyperglycemia was defined as two or more random glucose measurements ≥200mg/dl. Analyses of demographic and clinical factors were conducted with logistic regression.

Two hundred thirteen patients, median age 6years (range 1.0-18.9years), 47% female, were included. The prevalence of hyperglycemia was 23% (n=48). Mean glucose levels peaked 3days following administration of pegaspargase. In multivariable analysis, age ≥10years (odds ratio [OR] 6.2, 95% confidence interval [CI] 2.9are associated with insulin treatment. Frequent glucose monitoring is indicated during induction therapy for ALL.Cold and drought stress are the most critical stresses encountered by crops and occur simultaneously under field conditions. However, it is unclear whether volatiles contribute to both cold and drought tolerance, and if so, by what mechanisms they act. Here, we show that airborne eugenol can be taken up by the tea (Camellia sinensis) plant and metabolized into glycosides, thus enhancing cold and drought tolerance of tea plants. A uridine diphosphate (UDP)-glucosyltransferase, UGT71A59, was discovered, whose expression is strongly induced by multiple abiotic stresses. UGT71A59 specifically catalyzes glucosylation of eugenol glucoside in vitro and in vivo. Suppression of UGT71A59 expression in tea reduced the accumulation of eugenol glucoside, lowered reactive oxygen species (ROS) scavenging capacity, and ultimately impaired cold and drought stress tolerance. Exposure to airborne eugenol triggered a marked increase in UGT71A59 expression, eugenol glucoside accumulation, and cold tolerance by modulating ROS accumulation and CBF1 expression. It also promoted drought tolerance by altering abscisic acid homeostasis and stomatal closure. CBF1 and CBF3 play positive roles in eugenol-induced cold tolerance and CBF2 may be a negative regulator of eugenol-induced cold tolerance in tea plants. These results provide evidence that eugenol functions as a signal in cold and drought tolerance regulation and shed new light on the biological functions of volatiles in the response to multiple abiotic stresses in plants.In our previous studies, the offspring of morphine-exposed parents (MEO) showed pharmacological tolerance to the morphine's reinforcing effect. According to the role of exercise in treatment of morphine addiction, the current study was designed to utilize exercise to improve the effect of parental morphine exposure on the morphine's reinforcing effect. Male and female rats received morphine for 10 days and were drug-free for another 10 days. Each morphine-exposed animal was allowed to mate either with a drug-naïve or a morphine-exposed rat. The offspring were divided into two groups (1) offspring that were subjected to treadmill exercise and (2) offspring that were not subjected to exercise. The reinforcing effect of morphine was evaluated using conditioned place preference (CPP) and two-bottle choice (TBC) tests. Levels of dopamine receptors (D1DR and D2DR), μ-opioid receptor (MOR), and ΔFosB were evaluated in the nucleus accumbens. The MEO obtained lower preference scores in CPP and consumed morphine more than the control group in TBC. After 3 weeks of exercise, the reinforcing effect of morphine in the MEO was similar to the control. D1DR, D2DR, and MOR were increased in MEO compared with the controls before exercise. Levels of D1DR and MOR were decreased after exercise in the MEO; however, D1DR was increased in control. D2DR level did not change after exercise in MEO, but it increased in control group. Moreover, the level of ΔFosB was decreased among MEO while it was increased after exercise. In conclusion, exercise might modulate the reinforcing effect of morphine via alteration in levels of D1DR, MOR, and ΔFosB.The novel COVID pandemic has had a substantial impact on global mental health, including those populations that are inherently vulnerable such as pregnant and postpartum (perinatal) women. Anxiety disorders (ADs) are the most common mental health disorders during the perinatal period, affecting up to one in five women. However, since the onset of the pandemic, up to 60% of perinatal women are experiencing moderate to severe levels of anxiety. Given the substantial increase in perinatal anxiety during COVID, we sought to better understand its phenomenology by characterizing the collective worry content and impact of COVID using a content analysis. Eighty-four treatment-seeking pregnant (n = 35) and postpartum (n = 49) women with a principal AD, participated in this study between April and October 2020. In addition to completing questionnaire measures and a semistructured diagnostic interview, participants were asked to (1) describe their top excessive and uncontrollable worries, (2) describe additional COVID and non-COVID worries, and (3) describe how the pandemic had affected their lives. All responses were given verbally and transcribed verbatim by assessors. A content analysis led to the emergence of various COVID and non-COVID worry and impact themes. One third of participant's principal worries were specific to COVID, and 40% of COVID worries were specific to the perinatal context. Understanding the worry content and impact of COVID may improve symptom detection and inform the development of targeted treatment strategies to support the mental health needs of perinatal women with ADs throughout the pandemic and thereafter. Understanding pandemic-specific worries is important for perinatal symptom screening and may allow for the development of targeted treatment strategies to address COVID-specific worries and impact.Pyridoxine (vitamin B6) toxicity is known to cause a length-dependent, sensory predominant axonal polyneuropathy. There is debate regarding the threshold at which intake levels can cause neurological symptoms through pyridoxine toxicity. We asked if elevated plasma vitamin B6 levels were related to outcome measures in a well-characterized cohort of patients with chronic idiopathic axonal polyneuropathy (CIAP). We included 261 patients enrolled in the Peripheral Neuropathy Research Registry who had a complete dataset including a plasma vitamin B6 value. Patients with vitamin B6 deficiency (0-4.9 μg/L) were excluded. We performed a chi-square test for independence and analyzed the logistic relation of elevated plasma B6 level to nerve conduction studies (NCS), neurological examination findings, and patient-reported symptoms controlling for age and time elapsed since neuropathy symptom onset. Plasma B6 level was not related to neuropathy severity. There was no logistic relation of elevated plasma B6 level to NCS results, examination features including toe strength, vibration sense, and deep tendon reflexes, or patient-reported numbness or pain intensity.
