Adherence to Asacol once daily versus divided regimen for maintenance therapy in ulcerative colitis: a prospective, multicenter, randomized study

Background/Aims A once-daily (OD) regimen of 5-aminosalicylic acid (5-ASA) was easier to comply with than a divided daily (DD) regimen, and that treatment efficacy for ulcerative colitis (UC) was not affected by the dosing regimen. This study evaluated treatment adherence of OD and DD dosing in the Korean UC patients. Methods This study was a prospective, multicenter, randomized trial. UC patients were enrolled who have been in remission for more than 3 months. Patients were randomly assigned to the OD or DD group in a 1:1 ratio. The primary endpoint was adherence rate measured by tablet counts and self-reported adherence rate at 3, 6, 9, and 12 months. The relapse rate was measured at 1 year. Results Data from the 180 patients who were randomized were analyzed. Both self-reported adherence rate and adherence rate measured by tablet counts were not different at every points, including 1 year. The patients’ satisfaction of the OD group was higher than that of the DD group (P<0.001). At 1 year, 91.2% and 95.5% of patients in the OD group and DD group had maintained clinical remission, respectively (P=0.37). Conclusions The adherence rates were not different between the OD group and DD group. The patients’ satisfaction was higher in the OD group than in the DD group. 5-ASA OD dosing might have the same effect as DD for the maintenance of UC remission.
The balance simplex in non-competitive 2-species scaled Lotka–Volterra systems

ABSTRACT Explicit expressions in terms of Gaussian Hypergeometric functions are found for a ‘balance’ manifold that connects the non-zero steady states of a 2-species, non-competitive, scaled Lotka–Volterra system by the unique heteroclinic orbits. In this model, the parameters are the interspecific interaction coefficients which affects the form of the solution used. Similar to the carrying simplex of the competitive model, this balance simplex is the common boundary of the basin of repulsion of the origin and infinity, and is smooth except possibly at steady states.
Skin nerve pathology: Biomarkers of premanifest and manifest amyloid neuropathy

Small‐fiber sensory and autonomic symptoms are early presentations of familial amyloid polyneuropathy (FAP) with transthyretin (TTR) mutations. This study aimed to explore the potential of skin nerve pathologies as early and disease‐progression biomarkers and their relationship with skin amyloid deposits.
Er:Yag Laser Treatment of Simple Snorers in an Outpatient Setting

Objective: Snoring occurs as a result of soft tissue vibration caused by a partial upper airway collapse during sleep. This study evaluated the effectiveness and potential adverse side effects associated with the use of a nonsurgical, erbium-doped yttrium aluminum garnet (Er:YAG) laser treatment for patients with snoring conditions. Materials and Methods: In total, 33 patients with different degrees of snoring were analyzed retrospectively. All patients received three NightLase™ Er:YAG laser treatments. Results were measured using a follow-up questionnaire and then statistically analyzed. Any effects that occurred during the first year after treatment (i.e., short-term effects) were followed up with interviews. Results: Laser treatment effectively reduced patients' snoring and achieved a 65% satisfaction rate after three treatments. The greatest improvement and satisfaction were experienced by patients aged ≥50 years. Patients reported additional benefits from this treatment including easier breathing, higher alertness, and increased focus. Conclusion: Nonsurgical Er:YAG laser treatment is an effective and minimally invasive procedure to reduce patient snoring and other sleep-disordered breathing symptoms. Patients reported minimal disadvantages including minor discomfort and a low risk of side effects.
The effect of anodal/cathodal biphasic electrical stimulation on insulin release

We studied the effects of electrical stimulation on insulin release from rat insulinoma (INS‐1) cells. The anodal/cathodal biphasic stimulation (ACBPS) electrical waveform resulted in a voltage‐ and stimulation duration‐dependent increase in insulin release. ACBPS elicited insulin release both in the presence and absence of glucose. Basal and ACBPS‐induced insulin secretion could be inhibited by mitochondrial poisons and calcium channel blockers, indicating that insulin release was dependent on adenosine triphosphate (ATP) and the influx of calcium. ACBPS parameters that released insulin caused no detectable plasma membrane damage or cytotoxicity, although temporary morphological changes could be observed immediately after ACBPS. ACBPS did not alter the plasma membrane transmembrane potential but did cause pronounced uptake of MitoTracker Red into the mitochondrial membrane, indicating an increased mitochondrial membrane potential. While the ATP:ADP ratio after ACBPS did not change, the guanosine triphosphate (GTP) levels increased and increased GTP levels have previously been associated with insulin release in INS‐1 cells. These results provide evidence that ACBPS can have significant biological effects on cells. In the case of INS‐1 cells, ACBPS promotes insulin release without causing cytotoxicity.
Fresh perspectives on the roles of arbuscular mycorrhizal fungi in plant nutrition and growth

Recent research on arbuscular mycorrhizas has demonstrated that AM fungi play a significant role in plant phosphorus (P) uptake, regardless of whether the plant responds positively to colonization in terms of growth or P content. Here we focus particularly on implications of this finding for consideration of the balance between organic carbon (C) use by the fungi and P delivery (i.e. the C–P trade between the symbionts). Positive growth responses to arbuscular mycorrhizal (AM) colonization are attributed frequently to increased P uptake via the fungus, which results in relief of P deficiency and increased growth. Zero AM responses, compared with non-mycorrhizal (NM) plants, have conventionally been attributed to failure of the fungi to deliver P to the plants. Negative responses, combined with excessive C use, have been attributed to this failure. The fungi were viewed as parasites. Demonstration that the AM pathway of P uptake operates in such plants indicates that direct P uptake by the roots is reduced and that the fungi are not parasites but mutualists because they deliver P as well as using C. We suggest that poor plant growth is the result of P deficiency because AM fungi lower the amount of P taken up directly by roots but the AM uptake of P does compensate for the reduction. The implications of interplay between direct root uptake and AM fungal uptake of P also include increased tolerance of AM plants to toxins such as arsenate and increased success when competing with NM plants. Finally we discuss the new information on C–P trade in the context of control of the symbiosis by the fungus or the plant, including new information (from NM plants) on sugar transport and on the role of sucrose in the signaling network involved in responses of plants to P deprivation.
Weight or metabolism: which deserve more attention in obesity?

Obesity has become an important public health issue worldwide. A previous study has indicated that age-standardized average body mass index (BMI) increased from 21.7 kg/m 2 in 1975 to 24.2 kg/m 2 in 2014 in men, and from 22.1 to 24.4 kg/m 2 in women worldwide (1). With regard to children, it has been demonstrated that the global age-standardized prevalence of obesity increased from 0.7% in 1975 to 5.6% in 2016 in girls (5–19 years old), and from 0.9% to 7.8% in boys (5–19 years old) (2).
Effects of n-3 PUFA supplementation on plasma soluble adhesion molecules: a meta-analysis of randomized controlled trials.

BACKGROUND Previous studies indicate that oral supplementation with n-3 PUFA protects against atherosclerotic disease by inhibiting inflammatory processes, which underlie atherosclerosis and are reflected by the plasma concentrations of soluble adhesion molecules. However, consistent results were not obtained among studies. OBJECTIVE The objective was to assess the effects of n-3 PUFA supplementation on plasma concentrations of soluble adhesion molecules. DESIGN We conducted a meta-analysis of randomized controlled trials identified from PubMed, Embase, the Cochrane Library, and reference lists of relevant articles and reviews. RESULTS Eighteen studies were included. n-3 PUFA supplementation reduced plasma concentrations of soluble intercellular adhesion molecule-1 [sICAM-1; weighted mean difference (WMD): -5.17; 95% CI: -10.07, -0.27; P = 0.04] but had no significant effects on soluble vascular cell adhesion molecule-1 (WMD: -5.90; 95% CI: -17.63, 5.84; P = 0.32), soluble P-selectin (WMD: -1.53; 95% CI: -4.33, 1.28; P = 0.29), or soluble E-selectin (WMD: 0.46; 95% CI: -1.54, 2.46; P = 0.65). Subgroup analysis stratified by the subjects' health status showed that n-3 PUFA supplementation reduced sICAM-1 concentrations in healthy subjects (WMD: -8.87; 95% CI: -15.20, -2.53; P = 0.006; heterogeneity test: I² = 0%, P = 0.76) and in subjects with dyslipidemia (WMD: -15.31; 95% CI: -26.82, -3.81; P = 0.009; heterogeneity test: I² = 26%, P = 0.26). CONCLUSIONS n-3 PUFA supplementation can reduce plasma concentrations of sICAM-1. The effect is identified in both healthy subjects and subjects with dyslipidemia, which supports the hypothesis that n-3 PUFA can be supplemented as a primary or secondary means for preventing the development as well as the progression of atherosclerosis.
Tibiofemoral Joint Forces in Female Recreational Runners Vary with Step Frequency.

PURPOSE Elevated tibiofemoral joint (TFJ) contact forces have been linked to the development and progression of knee osteoarthritis. The primary objective of this study was to determine the association between peak TFJ shear and compression forces during running at different self-selected step frequencies (SF) in female recreational runners. METHODS Fifty-five healthy female recreational runners ran at 2.98 m·s on an instrumented treadmill. Peak TFJ anterior shear force, peak axial TFJ compression force, and peak medial compartment TFJ compression force were estimated using a musculoskeletal model with inputs from 3D joint kinematics and inverse dynamics calculations. Three SF groups were generated using tertiles, and differences between the groups were compared using one-way ANOVA (α = 0.05). RESULTS Runners with an SF of ≥178 steps per minute demonstrated the lowest peak TFJ anterior shear force (P = 0.04), peak axial TFJ compression force (P = 0.01), and peak TFJ medial compartment compression forces (P = 0.01) compared with runners using lower SF. CONCLUSION Female recreational runners with low SF of ≤166 steps per minute experience greater TFJ contact forces. This study provides evidence of an association between SF and both shear and axial peak TFJ contact forces during running.
cGMP-Elevating Compounds and Ischemic Conditioning Provide Cardioprotection Against Ischemia and Reperfusion Injury via Cardiomyocyte-Specific BK Channels

Background: The nitric oxide–sensitive guanylyl cyclase/cGMP-dependent protein kinase type I signaling pathway can afford protection against the ischemia/reperfusion injury that occurs during myocardial infarction. Reportedly, voltage and Ca2+-activated K+ channels of the BK type are stimulated by cGMP/cGMP-dependent protein kinase type I, and recent ex vivo studies implicated that increased BK activity favors the survival of the myocardium at ischemia/reperfusion. It remains unclear, however, whether the molecular events downstream of cGMP involve BK channels present in cardiomyocytes or in other cardiac cell types. Methods: Gene-targeted mice with a cardiomyocyte- or smooth muscle cell–specific deletion of the BK (CMBK or SMBK knockouts) were subjected to the open-chest model of myocardial infarction. Infarct sizes of the conditional mutants were compared with litter-matched controls, global BK knockout, and wild-type mice. Cardiac damage was assessed after mechanical conditioning or pharmacological stimulation of the cGMP pathway and by using direct modulators of BK. Long-term outcome was studied with respect to heart functions and cardiac fibrosis in a chronic myocardial infarction model. Results: Global BK knockouts and CMBK knockouts, in contrast with SMBK knockouts, exhibited significantly larger infarct sizes compared with their respective controls. Ablation of CMBK resulted in higher serum levels of cardiac troponin I and elevated amounts of reactive oxygen species, lower phosphorylated extracellular receptor kinase and phosphorylated AKT levels and an increase in myocardial apoptosis. Moreover, CMBK was required to allow beneficial effects of both nitric oxide–sensitive guanylyl cyclase activation and inhibition of the cGMP-degrading phosphodiesterase-5, ischemic preconditioning, and postconditioning regimens. To this end, after 4 weeks of reperfusion, fibrotic tissue increased and myocardial strain echocardiography was significantly compromised in CMBK-deficient mice. Conclusions: Lack of CMBK channels renders the heart more susceptible to ischemia/reperfusion injury, whereas the pathological events elicited by ischemia/reperfusion do not involve BK in vascular smooth muscle cells. BK seems to permit the protective effects triggered by cinaciguat, riociguat, and different phosphodiesterase-5 inhibitors and beneficial actions of ischemic preconditioning and ischemic postconditioning by a mechanism stemming primarily from cardiomyocytes. This study establishes mitochondrial CMBK channels as a promising target for limiting acute cardiac damage and adverse long-term events that occur after myocardial infarction.
Metabolic plasticity meets gene regulation

Tumor metabolism has been investigated as an exploitable avenue for treatment in the last several years. The link between tumor and metabolism traces its origin to a seminal observation by Otto Warburg, almost a century ago, that cancer cells, regardless of oxygen availability, convert most intracellular glucose to lactate—that is, aerobic glycolysis (1). This elevated glycolytic state of cancer cells has been elegantly exploited to detect tumors and their response to drugs by positron emission tomography through the use of fluorodeoxyglucose (2). Originally, tumor cells were thought to have dysfunctional mitochondria, but accumulating evidence suggests that they utilize glycolysis, oxidative phosphorylation, or both, depending on context unrelated to the integrity of mitochondria (3). Additionally, cancer cells can switch their metabolic phenotypes during tumor progression and metastasis and/or in response to external perturbations (4). This metabolic plasticity provides both the energy and the necessary intermediates for biosynthetic processes required for tumor growth. Recently, this “deregulation of cellular energetics” has been recognized as an emerging hallmark of cancer (5). Although our understanding of metabolic plasticity has increased over the years, the relationship between metabolism and gene regulatory networks (GRNs) remains understudied. In PNAS, using a systems-level approach, Jia et al. (6) explore the links between metabolism and gene regulation. Their key observation is that differential activity of the master regulators AMP-activated protein kinase (AMPK) and HIF-1 give rise to distinct metabolic phenotypes in cancer. Furthermore, based on experimentally validated model predictions, they demonstrate that cancer cells may exhibit additional metabolic states not usually present in normal cells, termed high-high or low-low. This intriguing conclusion challenges the conventional dichotomous classification of tumor metabolism as either glycolysis or oxidative phosphorylation (OXPHOS) and suggests novel avenues of experimentation. Metabolic pathways are interconnected and flexible, providing tumor cells with the property to reprogram their metabolism … [↵][1]1To whom correspondence should be addressed.

Reincarnation beliefs among Israeli Druze and the construction of a hard primordial identity

Abstract Most of the literature on reincarnation among the Druze attempts to shed light on its history and on those who believe in it. In this paper, we will argue that the Druze’s belief in reincarnation serves as one of the central components in defining their ethno-religious identity. Our study is based on an analysis of 30 semi-structured interviews with Israeli Druze university students. Findings suggest that the belief in reincarnation plays an important role in the lives of the Druze and it appears to serve as the most outstanding component in the young Druze’ definition of their primordial identity.
The Combined Impact of Sleep and Diet on Adiposity in Infants, Toddlers, and Young Children: A Systematic Review

Objective: Short sleep duration and poor dietary habits may contribute to increased adiposity; however, the impact of the interaction between these variables on adiposity is less understood. To evaluate research investigating the combined effects of sleep and diet on adiposity in infants, toddlers, and young children. Methods: Systematic searches of electronic databases (PubMed, CINAHL, and Web of Science) from inception through April 2017 were conducted. All studies published in English that had at least 1 sleep (e.g., sleep duration and night awakenings), diet (e.g., 24-hour diet recall and breastfeeding duration), and adiposity (e.g., body mass index z-score and weight-for-length) measure were eligible for inclusion. Abstract and full-text article reviews were conducted by 2 independent reviewers. Data were extracted into a standardized spreadsheet. Results: Of the 17 full-text articles reviewed, 14 studies were included. Mediation (n = 2) and moderation (n = 2) were seldom used. Investigation of the combined effects of sleep and diet on adiposity demonstrated a substantial lack of evidence. Synthesis of articles suggests that the relationship between sleep and diet may be interactive and their effects additive in their impact when targeted simultaneously within interventions. Conclusion: Without consideration of interaction effects among variables of interest, a substantial gap in the literature persists. Both diet and sleep need to be assessed simultaneously and repetitively in future longitudinal research.
Comparison of the Whole-Genome Sequence of an Oka Varicella Vaccine from China with Other Oka Vaccine Strains Reveals Sites Putatively Critical for Vaccine Efficacy

Varicella, also known as chickenpox, is a highly contagious disease, caused by varicella-zoster virus (VZV). Varicella is a common childhood disease that can be prevented by a live attenuated vaccine. The first available vaccine was derived from the parental Oka strain in Japan in 1974. Several live attenuated vaccines based on the Oka strain are currently available worldwide. Among the four vaccines produced in China, the vaccine manufactured by Changchun BCHT Biotechnology, also known as Baike, has been reported to be very efficacious. Comparative genomic analysis of the Baike vaccine with other Oka vaccine strains identified sites that might be involved in vaccine efficacy, as well as important for the biology of the virus. ABSTRACT Varicella-zoster virus (VZV) infection results in varicella mostly in children. Reactivation of the virus causes herpes zoster (HZ), mostly in adults. A live attenuated vaccine (vOka-Biken) was originally derived from the parental strain pOka. Several live attenuated vaccines based on the Oka strain are currently available worldwide. In China, varicella vaccines have been licensed by four manufacturers. In this study, we analyze the whole-genome sequence (WGS) of vOka-BK produced by Changchun BCHT Biotechnology also known as Baike. vOka-BK WGS was compared against the genomic sequences of four other Oka strains: pOka, vOka-Biken, vOka-Varilrix from GlaxoSmithKline, and vOka-Varivax from Merck & Co. A previous study identified 137 single nucleotide polymorphisms (SNPs) shared by all vOkas. The current analysis used these data as a reference to compare with vOka-BK WGS and focused on 54 SNPs located in the unique regions of the genome. Twenty-eight nonsynonymous substitutions were identified, ORF62 and ORF55 featuring the most amino acid changes with 9 and 3, respectively. Among the 54 SNPs, 10 had a different mutation profile in vOka-BK compared to the other three vaccines. A comparison with the clade 3 strain Ellen, known to be attenuated, identified three shared amino acid changes: *130R in ORF0 and R958G and S628G in ORF62. This analysis provides the first comparison of a Chinese varicella vaccine to the other vaccines available worldwide and identifies sites potentially critical for VZV vaccine efficacy.

Condensins and cohesins – one of these things is not like the other!

ABSTRACT Condensins and cohesins are highly conserved complexes that tether together DNA loci within a single DNA molecule to produce DNA loops. Condensin and cohesin structures, however, are different, and the DNA loops produced by each underlie distinct cell processes. Condensin rods compact chromosomes during mitosis, with condensin I and II complexes producing spatially defined and nested looping in metazoan cells. Structurally adaptive cohesin rings produce loops, which organize the genome during interphase. Cohesin-mediated loops, termed topologically associating domains or TADs, antagonize the formation of epigenetically defined but untethered DNA volumes, termed compartments. While condensin complexes formed through cis-interactions must maintain chromatin compaction throughout mitosis, cohesins remain highly dynamic during interphase to allow for transcription-mediated responses to external cues and the execution of developmental programs. Here, I review differences in condensin and cohesin structures, and highlight recent advances regarding the intramolecular or cis-based tetherings through which condensins compact DNA during mitosis and cohesins organize the genome during interphase. Summary: Condensins and cohesins generate intramolecular DNA loops. Condensin rods extrude DNA to compact chromatin during mitosis, whereas structurally adaptive cohesin rings organize the genome during interphase to regulate gene transcription.
