Abstract:

In the present investigation, the tautomeric and equilibrium of Cyanuric acid has been studied using Hartifock (HF) method in the gas phase and different solvents using the PCM model. The relative energies of these tautomers have been calculated at the HF level of theory using 6-311++ G (d,p) basis set. Energetics and relative stabilities of the tautomers were compared and analyzed in both the gaseous and different solvents. The results indicate that the keto tautomer (CA1) is the most stable form in the gas phase and other solvents. The order of stability of isomers was found to be CA1 > CA3> CA11> CA2> CA6> CA10> CA7> CA4> CA5> CA9>CA8. Having the largest dipole moment the CA8 tautomer is expected to have the strongest interaction with polar solvents. The HF method calculated tautomeric equilibrium constants with respect to the most stable tautomer CA1 of Cyanuric acid both in the gas and in different solvents. The of the equilibrium constants calculated starting from the general outline of interconversion.

Abstract:

Calcium-binding plays a decisive role in the folding and stabilization of many RTX proteins, especially for the RTX domain. Although many studies have been conducted to prove the contribution of Ca2+ ion toward the folding and stabilization of RTX proteins, its functional dynamics and conformational structural changes remain elusive. Here, molecular docking and molecular dynamics (MD) simulations were performed to analyze the contribution of Ca2+ ion toward the folding and stabilization of the RTX lipase (AMS8 lipase) structure. AMS8 lipase contains six Ca2+ ions (Ca1–Ca6). Three Ca2+ ions (Ca3, Ca4, and Ca5) were bound to the RTX parallel β-roll motif repeat structure (RTX domain). The metal ion (Ca2+) docking analysis gives a high binding energy, especially for Ca4 and Ca5 which are tightly bound to the RTX domain. The function of each Ca2+ ion is further analyzed using the MD simulation. The removal of Ca3, Ca4, and Ca5 caused the AMS8 lipase structure to become unstable and unfolded. The results suggested that Ca3, Ca4, and Ca5 stabilized the RTX domain. In conclusion, Ca3, Ca4, and Ca5 play a crucial role in the folding and stabilization of the RTX domain, which sustain the integrity of the overall AMS8 lipase structure.

Abstract:

In vivo Ca2+ imaging of neuronal populations in deep cortical layers has remained a major challenge, as the recording depth of two-photon microscopy is limited because of the scattering and absorption of photons in brain tissue. A possible strategy to increase the imaging depth is the use of red-shifted fluorescent dyes, as scattering of photons is reduced at long wavelengths. Here, we tested the red-shifted fluorescent Ca2+ indicator Cal-590 for deep tissue experiments in the mouse cortex in vivo. In experiments involving bulk loading of neurons with the acetoxymethyl (AM) ester version of Cal-590, combined two-photon imaging and cell-attached recordings revealed that, despite the relatively low affinity of Cal-590 for Ca2+ (Kd = 561 nM), single-action potential-evoked Ca2+ transients were discernable in most neurons with a good signal-to-noise ratio. Action potential-dependent Ca2+ transients were recorded in neurons of all six layers of the cortex at depths of up to −900 µm below the pial surface. We demonstrate that Cal-590 is also suited for multicolor functional imaging experiments in combination with other Ca2+ indicators. Ca2+ transients in the dendrites of an individual Oregon green 1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid-1 (OGB-1)-labeled neuron and the surrounding population of Cal-590-labeled cells were recorded simultaneously on two spectrally separated detection channels. We conclude that the red-shifted Ca2+ indicator Cal-590 is well suited for in vivo two-photon Ca2+ imaging experiments in all layers of mouse cortex. In combination with spectrally different Ca2+ indicators, such as OGB-1, Cal-590 can be readily used for simultaneous multicolor functional imaging experiments.

Abstract:

The present study was conducted to evaluate the effects of different dietary calcium levels on the growth and survival rate of black apple snails (Pila polita) in the grow-out period. There were 3 replicates for each treatment and the snails were fed with five calcium levels (% dry matter) in diet as follows: 1% (Ca1), 3% (Ca3), 5% (Ca5), 7% (Ca7), and 9% (Ca9). Two-month-old juveniles with an average initial body weight of 2.13g, shell height of 21.71mm, and shell width of 16.35mm were reared in tarpaulin tanks (1 × 1 × 1m; 40cm water depth) at the density of 100 individuals per tank. After 4 months of the rearing period, the average body weight, shell height, and shell width of the snails reached the highest values in the Ca5 treatment (28.43 g, 54.97 mm, and 40.09mm, respectively) and these values were significantly different compared to the remaining calcium contents (Ca1, Ca3, Ca7, and Ca9). The survival rate of the snails in Ca3 (75.7%) was higher than in Ca1 and Ca7 (74.7%), Ca5 (73.7%), and Ca9 (71.7%). However, the survival rate was not significantly different among the treatments. Snails in Ca5 obtained the highest productivity (2.88 kg m-2) and this value was significantly different from Ca1 (2.55 kg m-2) and Ca9 (2.35 kg m-2). The results of this study showed that the growth rate and productivity of black apple snails were highest when they consumed a diet containing 5% calcium. The optimum requirement of calcium for the black apple snails in the grow-out period was 4.51%.

Abstract:

Calmodulin (Cal) plays important roles for contractile activity in smooth muscles. Recently, two distinct Ca2+-binding protein superfamilies with sequence similarities to Cal have been identified in neuronal cells: neuronal Ca2+-binding proteins (NCBPs) and Cal-like Ca2+-binding proteins (CaBPs). Some NCBPs and CaBPs play significant roles for Ca2+-dependent cellular signaling in the nervous system. In gastrointestinal smooth muscles (GISMs), Cal functions as the regulator of contractile behavior and electrical rhythmicity. However, the molecular identification of NCBPs and CaBPs has not been elucidated in GISMs. Here, we have identified NCBPs and CaBPs expressed in GISMs and determined the expression levels of their transcripts by quantitative RT-PCR. Of 12 NCBPs, the transcripts for neuronal Ca2+sensor 1, neural visinin-like proteins 1, 2, and 3, and K+channel-interacting proteins 1 and 3 were detected in proximal colon, gastric fundus, gastric antrum, and jejunum. On the other hand, of seven CaBPs including alternatively spliced variants, only CaBP1L transcripts were detected in GISMs.

Abstract:

Background: Of the various techniques developed for the treatment of gum recession, the current innovation in the use of platelet rich plasma (PRF) has been applied to the treatment of root-end closure procedures. Purpose: This study analyzed the effect of the coronally advanced flap (CAF) in combination with platelet-rich fibrin (PRF) during treatment of gingival recession. Methods: This research constituted an experimental study incorporating a split-mouth design which was conducted on eight participants (with 16 recession defects) who were divided into two groups consisting of the CAF group with PRF and another CAF group without PRF. Clinical parameters consisting of gingival recession (GR), keratinized gingival width (KGW), recession width (RW) and clinical attachment level (CAL) were measured both before and 21 days after surgery). Results: The average differences between clinical parameters in the test group were as follows: GR (2.25 ± 0.27), KGW (1.81 ± 0.75), RW (3.44 ± 1.35), and CAL (2.56 ± 0.50); while in the control group they were as follows: GR (2.00 ± 0.71), KGW (1.94 ± 0.78), RW (3.50 ± 1.91) and CAL (2.00 ± 0.76). There were significant differences in the GR and CAL between the test and control groups (p ≤ 0.05). Conclusion: A combination of the CAF procedure and PRF was proven to be more effective in covering the GR and increasing the CAL.

Abstract:

BackgroundKawasaki disease (KD) is a nonspecific systemic vasculitic disease that frequently occurs among children, and coronary artery lesion (CAL) is the most serious complicationObjectivesWe aimed to study the risk factors for CAL in children with KDMethodsThere were examined 188 patients (boys:girls – 2:1, median age Me = 24 months [11;38]) with KD hospitalized in Morozovskaya Children’s City Clinical Hospital in 2014-2019. 19 (10,1%) of them were <6 months, 29 (15,4%) - 6-<12 months, 117 (62,3%) - 12 months-<5 years, 23 (12,2%) - ≥5 years. Univariate and multivariate logistic regression analyses were conducted to explore the relationships between CAL and gender, age, clinical diagnosis, laboratory biomarkers, initiation time of IVIG administration.ResultsThe enrolled 188 KD children were divided into a CAL group (n = 61) and an NCAL group (n =127) according to cardiac color Doppler ultrasonography. The incidence rate of CAL in the acute period was 26 %. The two groups had significantly different gender (p=0,0184), initiation time of IVIG administration (p=0,0209;)increase in platelets more than 700 000 at 2 weeks (p=0,0089), higher levels of NT-proBNP (p=0.002) and proANP (p=0,0005). Patients with CAL were found to have higher levels of NT-proBNP and proANP, suggesting a prognostic role. The NT-proBNP level was significantly higher in patients with CAL, and a cutoff value of 984 pg/mL yielded a sensitivity and specificity of 79 and 84.8 %, respectively. The area under the curve of the NT-proBNP for predicting CAA was 0.794 (95 % CI 0.620-0.967). The proANP level was significantly higher in patients with CAL, and a cutoff value of 1.015 nmol/L yielded a sensitivity and specificity of 87.5 and 75.8 %, respectively. The area under the curve of the proANP for predicting CAA was 0.805 (95 % CI 0.656-0.954).ConclusionMale gender, delayed use of IVIG, high platelets, NT-proBNP, proANP were independent risk factors for KD complicated with CAL. Current evidence suggests that NT-proBNP and proANP may be used as a diagnostic tool for KD complicated with CALDisclosure of InterestsNone declared

Abstract:

AbstractDiatoms and sediments were examined in a 530 cm core from Ishiba Ngandu, Zambia, a lake formed by gentle downwarping. Diatom zone D (>20 cal ka BP) was mostly sand with abundantAulacoseiraandEunotia, suggesting a shallow lake perhaps kept fresh by spring inputs and lake discharge, except during deposition of the lowermost 66 cm. Gyttja deposition between about 22 and 20 cal ka BP suggested a deeper lake and a wetter climate, perhaps because the Congo Air Boundary (CAB) was farther southeast relative to modern times. The next zone, zone C (about 20–19 cal ka BP), was sand with abundantAchnanthidiumandEunotiabut very few planktonic diatoms, apparently representing very shallow water and an arid period without the CAB. The gyttja and diatoms in zone B (19–4 ka) suggested an increase in moisture when the CAB returned. Zone A (4–0 cal ka BP) was dominated by the planktonicAulacoseira(>89%), suggesting an increase in wind-driven mixing. Uniquely, Ishiba Ngandu likely has been relatively moist since the last glacial maximum, matching pre-Holocene wetness in Botswana but not its Holocene aridity; evidently the climate here had switched to that of East Africa.

Abstract:

Streszczenie Na obszarze monokliny przedsudeckiej złoża gazu występują w utworach węglanowych cyklotemów PZ1 (w wapieniu podstawowym Cal) oraz PZ2 (w dolomicie głównym Ca2). Lokalizacja złóż jest ściśle związana ze strefami sedymentacji węglanów. Złoża występują przede wszystkim w obrębie stref barierowych oraz stref podnóża platform węglanowych. Wyrzut do chodnika rozdrobnionego materiału skalnego w KGHM ZG Rudna, który miał miejsce w 2009 r. pokazał, że gaz może występować również w strefie basenowej Cal, z którą związane jest złoże miedzi. Podstawową metodą badawczą wykorzystywaną do lokalizacji złóż węglowodorów są powierzchniowe badania sejsmiczne 2D i 3D. Ich sukcesy poszukiwawcze wynikają przede wszystkim z faktu zmniejszania się prędkości rozchodzenia się fal P oraz gęstości objętościowej pod wpływem nasycenia przestrzeni porowej gazem. Na skutek tego w rejestrowanym zapisie sejsmicznym widoczne są strefy zapisu anomalnego. Ich powiązanie ze złożami gazu, czyli złożowa interpretacja danych sejsmicznych, oparta jest na analizie DHI (Direct Hydrocarbon Indicator). W prezentowanej pracy przedstawiono i porównano sejsmiczne odwzorowanie nasycenia gazem „pułapek” zlokalizowanych w typowej barierze węglanowej (złoże Kościan w Cal), w strefie podnóża platformy węglanowej (złoże Lubiatów w Ca2) oraz porowatej/szczelinowatej strefie dolomitu Cal w rejonie wyrzutu gazu, który miał miejsce w KGHM ZG Rudna. Dla każdej ze stref opracowano, bazując na rejestrowanych danych geofizyki otworowej i modelowaniach 1D (sejsmogramy syntetyczne), kryteria identyfikacji stref nasyconych gazem. Podstawowym kryterium wskazującym na nasycenie (1) bariery Kościan (Cal) jest zmiana fazy refleksu (phase change) wiązanego ze spągiem Cal przy przejściu ze strefy basenowej (refleks ujemny) do strefy barierowej (refleks dodatni), (2) złoża Lubiatów, zlokalizowanego w obszarze podnóża platformy jest występowanie w stropie strefy nasyconej silnego refleksu ujemnego (bright spot), (3) porowatej i szczelinowej strefy głębokowodnej w ZG Rudna - występowanie w spągu dolomitów Cal refleksu o amplitudzie zbliżonej do zera. Opracowane kryteria są kryteriami lokalnymi, zbyt duża jest bowiem zmienność budowy geologicznej w różnych częściach basenu cechsztyńskiego.

Abstract:

This study was designed to clarify whether simulated microgravity can induce differential changes in the current and protein expression of the L-type Ca2+ channel (CaL) in cerebral and mesenteric arteries and whether these changes can be prevented by daily short-duration −Gx exposure. Tail suspension [hindlimb unloading (HU)] for 3 and 28 days was used to simulate short- and medium-term microgravity-induced deconditioning effects. Standing (STD) for 1 h/day was used to provide −Gx as a countermeasure. Whole cell patch-clamp experiments revealed an increase in current density of CaL of vascular smooth muscle cells (VSMCs) isolated from cerebral arteries of rats subjected to HU and a decrease in VSMCs from mesenteric arteries. Western blot analysis revealed a significant increase and decrease of CaL channel protein expression in cerebral and small mesenteric arterial VSMCs, respectively, only after 28 days of HU. STD for 1 h/day did not prevent the increase of CaL current density in cerebral arterial VSMCs, but it prevented completely (within 3 days) and partially (28 days) the decrease of CaL current density in small mesenteric arterial VSMCs. Consistent with the changes in CaL current, STD for 1 h/day did not prevent the increase of CaL expression in cerebrovascular myocytes but did prevent the reduction of CaL expression in mesenteric arterial VSMCs subjected to 28 days of HU. These data indicate that simulated microgravity up- and downregulates the current and expression of CaL in cerebral and hindquarter VSMCs, respectively. STD for 1 h/day differentially counteracted the changes of CaL function and expression in cerebral and hindquarter arterial VSMCs of HU rats, suggesting the complexity of the underlying mechanisms in the effectiveness of intermittent artificial gravity for prevention of postflight cardiovascular deconditioning, which needs further clarification.

Abstract:

Marine sponge-derived manoalide has a potent anti-inflammatory effect, but its potential application as an anti-cancer drug has not yet been extensively investigated. The purpose of this study is to evaluate the antiproliferative effects of manoalide on oral cancer cells. MTS assay at 24 h showed that manoalide inhibited the proliferation of six types of oral cancer cell lines (SCC9, HSC3, OC2, OECM-1, Ca9-22, and CAL 27) but did not affect the proliferation of normal oral cell line (human gingival fibroblasts (HGF-1)). Manoalide also inhibits the ATP production from 3D sphere formation of Ca9-22 and CAL 27 cells. Mechanically, manoalide induces subG1 accumulation in oral cancer cells. Manoalide also induces more annexin V expression in oral cancer Ca9-22 and CAL 27 cells than that of HGF-1 cells. Manoalide induces activation of caspase 3 (Cas 3), which is a hallmark of apoptosis in oral cancer cells, Ca9-22 and CAL 27. Inhibitors of Cas 8 and Cas 9 suppress manoalide-induced Cas 3 activation. Manoalide induces higher reactive oxygen species (ROS) productions in Ca9-22 and CAL 27 cells than in HGF-1 cells. This oxidative stress induction by manoalide is further supported by mitochondrial superoxide (MitoSOX) production and mitochondrial membrane potential (MitoMP) destruction in oral cancer cells. Subsequently, manoalide-induced oxidative stress leads to DNA damages, such as γH2AX and 8-oxo-2’-deoxyguanosine (8-oxodG), in oral cancer cells. Effects, such as enhanced antiproliferation, apoptosis, oxidative stress, and DNA damage, in manoalide-treated oral cancer cells were suppressed by inhibitors of oxidative stress or apoptosis, or both, such as N-acetylcysteine (NAC) and Z-VAD-FMK (Z-VAD). Moreover, mitochondria-targeted superoxide inhibitor MitoTEMPO suppresses manoalide-induced MitoSOX generation and γH2AX/8-oxodG DNA damages. This study validates the preferential antiproliferation effect of manoalide and explores the oxidative stress-dependent mechanisms in anti-oral cancer treatment.

Abstract:

Background. To improve the efficacy of regenerative treatment for gingival recessions, the autologous platelet concentrates (APCs) combined with coronally advanced flap (CAF) have been investigated. However, few studies systematically assess the complementary effect of APCs in periodontal regeneration. The present study aims to evaluate the additional effect of different types of APCs to CAF in the treatment of gingival recessions. Methods. Electronic databases (EMBASE, MEDLINE, and Cochrane Central Register of Controlled Trails) and relevant journals were searched until May 15, 2019. Only randomized controlled trials (RCTs) in English were included. Outcome variables include root coverage (RC), recession depth (RD), clinical attachment level (CAL), keratinized tissue width (KTW), and gingival thickness (GT). Data were analyzed with Revman5.3. The estimate of effect sizes was expressed as the mean differences and the 95% confidence interval. Results. 8 RCTs involving 170 patients (328 sites) were included. Our meta-analysis indicated RC, RD, CAL, KTW, and GT were better improved in the CAF plus APCs groups than the CAF alone. The subgroup analyses revealed that platelet-rich fibrin (PRF) brought significant improvement in RC, RD, CAL, and GT. Concentrated growth factors (CGF) lead clinic beneficial in CAL, KTW, and GT. No significant effect of platelet-rich plasma (PRP) could be found in any clinical parameters when combined with CAF. Conclusions. PRF could exert additional effect to CAF; the preferred treatment for gingival recessions was considered. Based on the limited studies, it seemed that PRP failed to show any additional effect and it was not suggested for gingival recessions. Given the limited research and high risk of bias, it is still needed to confirm the additional effect of CGF by more high-quality studies.

Abstract:

AbstractIn this paper we study linear fractional relations defined in the following way. Let ${\cal B}$i, ${\cal B}$'i, i = 1,2, be Banach spaces. We denote the space of bounded linear operators by ${\cal L}$. Let T ε ${\cal L}$(${\cal B}$1 ⊕ ${\cal B}$2, ${\cal B}$'1 ⊕ ${\cal B}$'2). To each such operator there corresponds a 2 × 2 operator matrix of the form (*) where Tij ε ${\cal L}$ (${\cal B}$j, ${\cal B}$'i. For each such T we define a set-valued map GT from ${\cal L}$ (${\cal B}$1, ${\cal B}$2) into the set of closed affine subspaces of ${\cal L}$ (${\cal B}$'1, ${\cal B}$'2) by The map GT is called a linear fractional relation.The paper is devoted to the following two problems. •Characterization of operator matrices of the form (*) for which the set GT(K) is non-empty for each K in some open ball of the space ${\cal L}$ (${\cal B}$1,${\cal B}$2).•Characterizations of quadruples (${\cal B}$1, ${\cal B}$2, ${\cal B}$'1, ${\cal B}$'2) of Banach spaces such that linear fractional relations defined for such spaces satisfy the natural analogue of the Liouville theorem “a bounded entire function is constant”.

Abstract:

AbstractThe inexpressive Description Logic (DL) ${\cal F}{{\cal L}_0}$ , which has conjunction and value restriction as its only concept constructors, had fallen into disrepute when it turned out that reasoning in ${\cal F}{{\cal L}_0}$ w.r.t. general TBoxes is ExpTime-complete, that is, as hard as in the considerably more expressive logic ${\cal A}{\cal L}{\cal C}$ . In this paper, we rehabilitate ${\cal F}{{\cal L}_0}$ by presenting a dedicated subsumption algorithm for ${\cal F}{{\cal L}_0}$ , which is much simpler than the tableau-based algorithms employed by highly optimized DL reasoners. Our experiments show that the performance of our novel algorithm, as prototypically implemented in our ${\cal F}{{\cal L}_0}$ wer reasoner, compares very well with that of the highly optimized reasoners. ${\cal F}{{\cal L}_0}$ wer can also deal with ontologies written in the extension ${\cal F}{{\cal L}_ \bot }$ of ${\cal F}{{\cal L}_0}$ with the top and the bottom concept by employing a polynomial-time reduction, shown in this paper, which eliminates top and bottom. We also investigate the complexity of reasoning in DLs related to the Horn-fragments of ${\cal F}{{\cal L}_0}$ and ${\cal F}{{\cal L}_ \bot }$ .

Abstract:

Exposure to microgravity leads to a sustained elevation in transmural pressure across the cerebral vasculature due to removal of hydrostatic pressure gradients. We hypothesized that ion channel remodeling in cerebral vascular smooth muscle cells (VSMCs) similar to that associated with hypertension may occur and play a role in upward autoregulation of cerebral vessels during microgravity. Sprague-Dawley rats were subjected to 4-wk tail suspension (Sus) to simulate the cardiovascular effect of microgravity. Large-conductance Ca2+-activated K+ (BKCa), voltage-gated K+ (KV), and L-type voltage-dependent Ca2+ (CaL) currents of Sus and control (Con) rat cerebral VSMCs were investigated with a whole cell voltage-clamp technique. Under the same experimental conditions, KV, BKCa, and CaL currents of cerebral VSMCs from adult spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY) were also investigated. KV current density decreased in Sus rats vs. Con rats [1.07 ± 0.14 ( n = 22) vs. 1.31 ± 0.28 ( n = 16) pA/pF at +20 mV ( P < 0.05)] and BKCa and CaL current densities increased [BKCa: 1.70 ± 0.37 ( n = 23) vs. 0.88 ± 0.22 ( n = 19) pA/pF at +20 mV ( P < 0.05); CaL: −2.17 ± 0.21 ( n = 35) vs. −1.31 ± 0.10 ( n = 26) pA/pF at +10 mV ( P < 0.05)]. Similar changes were also observed in SHR vs. WKY cerebral VSMCs: KV current density decreased [1.03 ± 0.33 ( n = 9) vs. 1.62 ± 0.64 ( n = 9) pA/pF at +20 mV ( P < 0.05)] and BKCa and CaL current densities increased [BKCa: 2.54 ± 0.47 ( n = 11) vs. 1.12 ± 0.33 ( n = 12) pA/pF at +20 mV ( P < 0.05); CaL: −3.99 ± 0.53 ( n = 12) vs. −2.28 ± 0.20 ( n = 10) pA/pF at +20 mV ( P < 0.05)]. These findings support our hypothesis, and their impact on space cardiovascular research is discussed.
