Effects of body weight and fiber sources on fiber digestibility and short chain fatty acid concentration in growing pigs

Objective The study was conducted to determine the effects of body weight (BW) and fiber sources on nutrient digestibility, fiber fermentation and short chain fatty acids (SCFA) concentration in different intestinal segments of growing pigs fed high-fiber diets. Methods Nine barrows with initial BW of 25.17±0.73 kg and 9 barrows with initial BW of 63.47±2.18 kg were allotted to a duplicate 9×2 Youden Square design with 3 dietary treatments and 2 periods. The dietary treatments were formulated with 3 different high-fiber ingredients: corn bran, sugar beet pulp, and soybean hulls, respectively. Each diet was fed to 3 barrows with different stage of BW in each period. Results There were no differences in the apparent ileal digestibility (AID) of most nutrients between pigs at different BW stages. Pigs at 60 kg had greater (p<0.05) apparent total tract digestibility (ATTD) of total dietary fiber (TDF), soluble dietary fiber (SDF) and insoluble dietary fiber (IDF), and had greater (p<0.05) hindgut disappearance of IDF and cellulose than pigs at 25 kg. The acetate, propionate and total SCFA concentrations in ileal digesta and feces of pigs at 60 kg were greater (p<0.05) than those of pigs at 25 kg. In addition, fiber sources affected (p<0.05) the AID of gross energy (GE), organic matter (OM), ether extract (EE), crude protein, SDF and hemicellulose, the hindgut disappearance and ATTD of dietary fiber components, the lactate and propionate concentrations in ileal digesta and the butyrate, valerate and total SCFA concentrations in feces. There were interactions (p<0.05) between BW and fiber sources on the AID of GE, OM, EE, SDF, hemicellulose, the ATTD of EE, TDF, and IDF, and the hindgut disappearance of SDF and hemicellulose. Conclusion Increasing BW mainly improved the digestibility of dietary fiber fractions, and the dietary fiber sources influenced the digestibility of almost all the dietary nutrients in growing pigs.

The role of genotype/phenotype at apurinic/apyrimidinic endonuclease Rs1130409 in renal cell carcinoma

The DNA repair capacity plays a critical role in maintaining the genomic stability and gatekeeping for individual cancer risk. In this study, we aim at evaluation the role of the Asp148Glu (rs1130409) variant at apurinic/apyrimidinic endonuclease (APE) gene in renal cell carcinoma (RCC) risk and the contribution of different genotypes to its transcriptional mRNA levels. In the case–control study, 92 RCC patients and 580 cancer-free patients matched by age and gender were recruited. The apurinic/APE genotyping work was conducted with typical restriction fragment length polymorphism methodology after polymerase chain reaction. At the meanwhile, thirty renal tissue samples with variant genotypes were examined for their apurinic/APE mRNA and protein expressions by real-time quantitative reverse transcription method and Western blotting. The results showed that compared with the wild-type TT genotype, the people with TG and GG genotypes of apurinic/APE Asp148Glu had 0.88- and 1.09-fold risk of RCC, respectively. We have also examined the in vivo transcriptional (RNA) and translational (protein) levels with renal tissues of various apurinic/APE Asp148Glu genotypes, revealing that the apurinic/APE mRNA and protein were of similar levels among people of TT, TG, or GG genotypes. There was no joint gene-environment effect of apurinic/APE Asp148Glu genotype and smoking habit on RCC risk. The evidence indicated that apurinic/APE Asp148Glu genotypic variants did not alter its mRNA and protein expression among RCC patients. The genotype of apurinic/APE Asp148Glu may not serve as a proper predictive marker for RCC risk in Taiwan.
Two-Step Patterning of Scalable All-Inorganic Halide Perovskite Arrays.

Halide perovskites have many important optoelectronic properties, including high emission efficiency, high absorption coefficients, color purity and tunable emission wavelength, which makes this material promising for optoelectronic applications. However, the inability to precisely control large-scale patterned growth of halide perovskites limits their potential toward various device applications. Here, we report a patterning method for the growth of cesium lead halide perovskite single crystal array. Our approach is consisted of two steps: (1) cesium halide salt arrays patterning and (2) chemical vapor transport (CVT) process to convert salt arrays into single crystal perovskite arrays. Characterizations including energy-dispersive x-ray spectroscopy and photoluminescence have been employed to confirm the chemical compositions and the optical properties of the as-synthesized perovskite arrays. This patterning method enables the patterning of single crystal cesium lead halide perovskite arrays with tunable spacing (from 2 µm to 20 µm) and crystal size (from 200 nm to 1.2 µm) in high production yield (almost every pixel in the array is successfully grown with a converted perovskite crystals). Our large-scale patterning method renders a platform for study of fundamental properties and opportunities for novel perovskite-based optoelectronic applications.
Association between neurological deterioration and outcomes in patients with stroke.

Background Neurological deterioration (ND) shortly after stroke is common in Chinese patients. We aimed to determine the effects of ND during hospitalization on stroke prognosis. Methods We retrospectively reviewed files from the stroke registry of the Department of Neurology of Tianjin Huanhu Hospital between October 1, 2008, and December 31, 2015. The inclusion criteria were: age ≥18 years, diagnosis of acute ischemic stroke, and first-ever ischemic stroke occurring within 7 days prior to admission. ND was defined as an increase in the National Institutes of Health Stroke Scale (NIHSS) score by ≥4 points during hospitalization. Early neurological deterioration (END) was defined as an increase in the NIHSS score by ≥4 points between the baseline and 48-hour evaluations. Late neurological deterioration (LND) was defined as an increase in the NIHSS score by ≥4 points between the 48-hour and discharge evaluations. Multivariate regression was used to evaluate the relationship between early and late ND and short- and long-term outcomes. Primary and secondary outcomes based on the modified Rankin scale (mRS) were evaluated at 3 months and 1 year. Favorable and poor outcomes were defined as mRS scores of 0-2 and ≥3, respectively. Results A total of 9,650 patients were included. ND occurred in 293 patients (3.0%) during hospitalization. Among them, 192 (65.5%) were in the END group, and 101 (34.5%) were in the LND group. After adjusting for age, gender, and NIHSS scores, END was a significant independent predictor of poor outcome at both 3 months (primary outcome OR 8.069, secondary outcome OR 8.194) and 1 year (primary outcome OR 7.895, secondary outcome OR 5.679). The same pattern was seen in the LND group (3 months primary outcome OR 7.608, secondary outcome OR 6.349, 1-year primary outcome OR 10.793, secondary outcome OR 5.245). Conclusions ND during hospitalization, regardless of whether it occurs in the early or late period after stroke, is an independent predictor of poor prognosis.
Lower Extremity Motor Deficits Are Underappreciated in Patient-Reported Outcome Measures: Added Value of Objective Outcome Measures

Objective The patient-reported outcome measure (PROM)-based evaluation in lumbar degenerative disc disease (DDD) is today’s gold standard but has limitations. We studied the impact of lower extremity motor deficits (LEMDs) on PROMs and a new objective outcome measure. Methods We evaluated patients with lumbar DDD from a prospective 2-center database. LEMDs were graded according to the British Medical Research Council (BMRC; 5 [normal] –0 [no movement]). The PROM-based evaluation included pain (visual analogue scale), disability (Oswestry Disability Index [ODI] & Roland-Morris Disability Index [RMDI]), and health-related quality of life (HRQoL; Short-Form 12 physical component summary/mental component summary & EuroQol-5D index). Objective functional impairment (OFI) was determined as age- and sex-adjusted Timed-Up and Go (TUG) test value. Results One hundred five of 375 patients (28.0%) had a LEMD. Patients with LEMD had slightly higher disability (ODI: 52.8 vs. 48.2, p = 0.025; RMDI: 12.6 vs. 11.3, p = 0.034) but similar pain and HRQoL scores. OFI T-scores were significantly higher in patients with LEMD (144.2 vs. 124.3, p = 0.006). When comparing patients with high- (BMRC 0–2) vs. low-grade LEMD (BMRC 3–4), no difference was evident for the PROM-based evaluation (all p > 0.05) but patients with high-grade LEMD had markedly higher OFI T-scores (280.9 vs. 136.0, p = 0.001). Patients with LEMD had longer TUG test times and OFI T-scores than matched controls without LEMDs. Conclusion Our data suggest that PROMs fail to sufficiently account for LEMD-associated disability, which is common and oftentimes bothersome to patients. The objective functional evaluation with the TUG test appears to be more sensitive to LEMD-associated disability. An objective functional evaluation of patients with LEMD appears reasonable.
Complex Mitochondrial Dysfunction Induced by TPP+-Gentisic Acid and Mitochondrial Translation Inhibition by Doxycycline Evokes Synergistic Lethality in Breast Cancer Cells

The mitochondrion has emerged as a promising therapeutic target for novel cancer treatments because of its essential role in tumorigenesis and resistance to chemotherapy. Previously, we described a natural compound, 10-((2,5-dihydroxybenzoyl)oxy)decyl) triphenylphosphonium bromide (GA-TPP+C10), with a hydroquinone scaffold that selectively targets the mitochondria of breast cancer (BC) cells by binding to the triphenylphosphonium group as a chemical chaperone; however, the mechanism of action remains unclear. In this work, we showed that GA-TPP+C10 causes time-dependent complex inhibition of the mitochondrial bioenergetics of BC cells, characterized by (1) an initial phase of mitochondrial uptake with an uncoupling effect of oxidative phosphorylation, as previously reported, (2) inhibition of Complex I-dependent respiration, and (3) a late phase of mitochondrial accumulation with inhibition of α-ketoglutarate dehydrogenase complex (αKGDHC) activity. These events led to cell cycle arrest in the G1 phase and cell death at 24 and 48 h of exposure, and the cells were rescued by the addition of the cell-penetrating metabolic intermediates l-aspartic acid β-methyl ester (mAsp) and dimethyl α-ketoglutarate (dm-KG). In addition, this unexpected blocking of mitochondrial function triggered metabolic remodeling toward glycolysis, AMPK activation, increased expression of proliferator-activated receptor gamma coactivator 1-alpha (pgc1α) and electron transport chain (ETC) component-related genes encoded by mitochondrial DNA and downregulation of the uncoupling proteins ucp3 and ucp4, suggesting an AMPK-dependent prosurvival adaptive response in cancer cells. Consistent with this finding, we showed that inhibition of mitochondrial translation with doxycycline, a broad-spectrum antibiotic that inhibits the 28 S subunit of the mitochondrial ribosome, in the presence of GA-TPP+C10 significantly reduces the mt-CO1 and VDAC protein levels and the FCCP-stimulated maximal electron flux and promotes selective and synergistic cytotoxic effects on BC cells at 24 h of treatment. Based on our results, we propose that this combined strategy based on blockage of the adaptive response induced by mitochondrial bioenergetic inhibition may have therapeutic relevance in BC.
Timing eclipses amount: The critical importance of intermittency in alcohol exposure effects.

Frequency and duration of ethanol (EtOH) exposures influence the consequences of those experiences, with evidence building from basic science studies in rats and mice that intermittent alcohol access (IAA) typically produces a greater escalation of EtOH intake than more continuous alcohol access (CAA). IAA also better simulates human use patterns where alcohol levels typically clear from the body between periods of use. A variety of mechanisms have been proposed to contribute to the enhanced intake of EtOH induced by IAA, including a possible attenuation in the aversive effects of EtOH, although further studies are needed to address this and other possibilities. Neural differences include indications of an IAA-associated increase in NR2B receptors that is not evident with CAA; although little studied, alterations in other neural and neurotransmitter systems are evident as well. Many gaps in understanding of IAA/CAA effects remain. Further work is needed to characterize neural mechanisms underlying these effects, consequences of IAA/CAA on EtOH effects beyond intake, and the impact of stress and environmental variables on these differences. IAA/CAA studies to date have also largely been limited to males and to adult animals and hence more studies examining IAA/CAA across sex and age are needed. Such additional work is essential to determine unique contributors to IAA-induced elevations in EtOH intake that may provide important insights for development of new prevention/intervention strategies for heavy alcohol use and abuse.
Numerical Investigation on Multiple Resonant Modes of Double-Layer Plasmonic Grooves for Sensing Application

A high-performance multi-resonance plasmonic sensor with double-layer metallic grooves is theoretically constructed by introducing a polymethyl methacrylate groove with a numerical simulation method. Multiple resonance wavelengths can be generated at the oblique incidence, and the number and feature of resonant mode for sensing detection is different for various incident angles. Specifically, at the incident angle of 30°, the reflection spectrum exhibits two resonant dips, in which the dip at the wavelength of 1066 nm has an extremely narrow line width of ~4.5 nm and high figure of merit of ~111.11. As the incident angle increases, the electric dipole mode gradually weakens, but the surface plasmon resonance and cavity resonance mode are enhanced. Therefore, for an incident angle of 65°, three resonance dips for sensing can be generated in the reflection spectrum to realize three-channel sensing measurement. These double-layer plasmonic grooves have potential in the development of advanced biochemical surface plasmon polariton measurements.
Failure of multiplex meningitis/encephalitis (ME) NAT during cryptococcal meningitis in solid organ recipients

Cryptococcal meningitis is a severe cause of central nervous system infections among immunocompromised solid organ transplant (SOT) patients. While new diagnostic methods as multiplex meningitis/encephalitis (ME) NAT (nucleic acid test) are increasingly used as a first‐line tool in hospital practice, data in HIV‐negative patients including SOT remain scarce. We report here false‐negative results of multiplex NAT among SOT patients with proven cryptococcal meningitis.
Disease recovery in bats affected by white-nose syndrome

ABSTRACT Processes associated with recovery of survivors are understudied components of wildlife infectious diseases. White-nose syndrome (WNS) in bats provides an opportunity to study recovery of disease survivors, understand implications of recovery for individual energetics, and assess the role of survivors in pathogen transmission. We documented temporal patterns of recovery from WNS in little brown bats (Myotis lucifugus) following hibernation to test the hypotheses that: (1) recovery of wing structure from WNS matches a rapid time scale (i.e. approximately 30 days) suggested by data from free-ranging bats; (2) torpor expression plays a role in recovery; (3) wing physiological function returns to normal alongside structural recovery; and (4) pathogen loads decline quickly during recovery. We collected naturally infected bats at the end of hibernation, brought them into captivity, and quantified recovery over 40 days by monitoring body mass, wing damage, thermoregulation, histopathology of wing biopsies, skin surface lipids and fungal load. Most metrics returned to normal within 30 days, although wing damage was still detectable at the end of the study. Torpor expression declined overall throughout the study, but bats expressed relatively shallow torpor bouts – with a plateau in minimum skin temperature – during intensive healing between approximately days 8 and 15. Pathogen loads were nearly undetectable after the first week of the study, but some bats were still detectably infected at day 40. Our results suggest that healing bats face a severe energetic imbalance during early recovery from direct costs of healing and reduced foraging efficiency. Management of WNS should not rely solely on actions during winter, but should also aim to support energy balance of recovering bats during spring and summer. Highlighted Article: During the recovery process of survivors of white-nose syndrome, bats exhibited rapid mass gain and tissue healing. Healing appears to cause a trade-off between energy conservation and recovery.
Zeolite-Enhanced Sustainable Pd Catalyzed C-C Cross-Coupling Reaction: Controlled Release and Capture of Palladium.

Supported palladium catalysts have attracted significant attention for use in cross-coupling reactions due to their recyclability. However, the inevitable progressive loss of Pd that occurs in the catalytic process deactivates the catalysts, which hinders their sustainable application. Herein, we report a zeolite-enhanced sustainable Pd catalyst for C-C cross-coupling reactions. Zeolite does a nice job of acting as a sink for Pd2+ ions. This catalyst exhibits an excellent homogeneous catalytic performance by releasing Pd species from zeolite. In addition, the Pd2+ ions were successfully recaptured in a controlled catalytic system by combining the uniform microporous structure and good adsorption features of zeolite. The release/capture mechanism of the Pd species guaranteed the high loading and high dispersion of Pd on the recycled catalyst. The 0.84%Pd@USY catalysts were reused at least 10 times in water without an appreciable reduction in activity. This study presents a new perspective toward the design of a highly efficient and sustainable supported metal catalyst.

Hippocampal changes in mice lacking an active prohormone convertase 2

Prohormone convertase 2 (PC2) is essential for the biosynthesis of many neuropeptides, including several of them in hippocampus. In mouse brain, lacking an enzymatically active PC2 (PC2‐null) causes accumulation of many neuropeptides in their precursor or intermediate forms. Little is known about how a PC2‐null state may affect the function of the hippocampus. In this study, adult PC2‐null mice and their wildtype (WT) littermates were subjected to three analyses to determine possible changes associated with PC2‐null at physiological, behavioral, and molecular levels, respectively, under normal and stressed conditions. Electrophysiological recordings of hippocampal slices were performed to measure evoked field‐excitatory postsynaptic potentials (EPSP), long‐term potentiation (LTP), and paired‐pulse facilitation (PPF). Morris water maze (MWM) testing was conducted to examine behavioral changes that are indicative of hippocampal integrity. Quantitative mass spectrometry analysis was used to determine changes in the hippocampal proteome in response to a focal cerebral ischemic insult. We found that there were no significant differences in the threshold of evoked EPSPs between PC2‐null and WT animals. However, an increase in LTP in both triggering rate and amplitude was observed in PC2‐null mice, suggesting that PC2 may be involved in regulating synaptic strength. The PPF, on the other hand, showed a decrease in PC2‐null mice, suggesting a presynaptic mechanism. Consistent with changes in LTP, PC2‐null mice displayed decreased latencies in finding the escape platform in the MWM test. Further, after distal focal cerebral ischemia, the hippocampal proteomes incurred changes in both WT and PC2‐null mice, with a prominent change in proteins associated with neurotransmission, exocytosis, and transport processes seen in the PC2‐null but not WT mice. Taken together, our results suggest that PC2 is involved in regulating hippocampal synaptic plasticity, learning, and memory behaviors, as well as the hippocampal response to stresses originating in other regions of the brain.
