Anti-glycemic potential of Abelmoschus caillei (A. Chev.) Stevels Pod aqueous and methanol extract on streptozotocin-induced diabetic rats

Diabetes mellitus is a lingering disease associated with pancreatic malfunctioning unable to synthesize sufficient insulin, or the insulin produced by the body cannot be effectively utilized, resulting in the accumulation of glucose in the body. This study evaluates the anti-diabetic activity of the aqueous and methanol extracts of Abelmoschus caillei in Streptozotocin-induced diabetic rats. Thirty male rats were administered with 45 mg/kg Streptozotocin (STZ) to induce-diabetes for 3 days and thereafter treated with graded oral doses of 200 and 400 mg/kg of aqueous and methanol pod extracts of A. caillei for 28 days. Hematological analysis, biochemical analysis and histopathology of the heart, were carried out using standard procedures. The results from this study showed a significant reduction in the elevated blood glucose levels at day 28 of the aqueous and methanol extracts (67.37; 130 mg/dL and 173.0; 140.0 mg/dL) with percentage reduction of (68.29; 56.3% and 30.7; 45.8%) respectively when compared with glibenclamide group and diabetes control (220.7 mg/dl; 43.98 % and 418.7 mg/dl; 0%). The hematological, lipid profile and liver function test had a slight significant difference specifically at 400 mg/kg of the extracts when compared with the control p> 0.05. The architectural frame work of the organ’s histopathology elicited no deformities in liver, kidney, pancreases, lungs, and heart the treated groups when compared with the diabetic control. This study showed that A. caillei extracts possess anti-diabetic potentials, thereby supporting the claims in the management of diabetes from the traditional folk’s report.
Radiative corrections to vectorlike portal dark matter

A massive real scalar dark matter particle $S$ can couple to Standard Model leptons or quarks through a vector-like fermionic mediator $\psi$, a scenario known as the Vector-like portal. Due to helicity suppression of the annihilation cross section into a pair of SM fermions, it has been shown in previous works that radiative corrections, either at one-loop or through radiation of gauge bosons, may play a significant role both in determining the relic abundance and for indirect detection. All previous works considered the limit of massless final state quarks or leptons. In this work, we focus on a technical issue, which is to reliably determine the annihilation cross sections taking into account finite fermion masses. Following previous works in the framework of simplified supersymmetric dark matter scenarios, and building on an analogy with Higgs decay into fermions, we address the issue of infrared and collinear divergences that plagues the cross section by adopting an effective operator description, which captures most of the relevant physics and give explicit expressions for the annihilation cross sections. We then develop several approximations for the differential and total cross sections, which simplify greatly their expressions, and which can then be used in various phenomenological studies of similar models. Finally, we describe our method to compute the final gamma-ray spectrum, including hadronisation of the heavy fermions, and provide some illustrative spectra for specific dark matter candidates.
The Impact of Perceived Service Quality on Customer Loyalty towards Chinese Fitness Centres: The Moderating Role of Reputation/Image

The trend of joining a fitness club has been growing rapidly since the last decade, but it's difficult to justify the actual reason which can keep the members of the club loyal. This study has indicated some key reasons for customer loyalty, including perceived service quality and customer satisfaction which is influenced by customer delight. Therefore, the basic aim of this research is to explore the effect of perceived service quality on customer loyalty. To explore the relationships made by deep literature analysis, this research collected data from 411 members of Chinese fitness clubs. This data was further observed in AMOS software to ensure the results of the hypothesis. The results highlighted that there is a significant and positive impact of perceived service quality on customer delight and customer loyalty. The delighted customer will be satisfied and that satisfaction will lead to customer loyalty. In addition, reputation and image can significantly moderate the relationship between customer satisfaction and customer loyalty. The managers of owners of fitness clubs can seek the important results highlighted by this research for developing marketing strategies for clubs.
The magnetic propeller accretion regime of LkCa 15

We present a spectropolarimetric study of the classical T Tauri star (cTTS) LkCa 15 investigating the large-scale magnetic topology of the central star and the way the field connects to the inner regions of the accretion disc. We find that the star hosts a strong poloidal field with a mainly axisymmetric dipole component of 1.35 kG, whereas the mass accretion rate at the surface of the star is $10^{-9.2}$ $\hbox{${\rm M}_{\odot}$ yr$^{-1}$}$. It implies that the magnetic field of LkCa 15 is able to evacuate the central regions of the disc up to a distance of 0.07 au at which the Keplerian orbital period equals the stellar rotation period. Our results suggest that LkCa 15, like the lower-mass cTTS AA Tau, interacts with its disc in a propeller mode, a regime supposedly very efficient at slowing down the rotation of cTTSs hosting strong dipolar fields.
Open Wilson lines and generalized star product in noncommutative scalar field theories

Open Wilson line operators and a generalized star product have been studied extensively in noncommutative gauge theories. We show that they also show up in noncommutative scalar field theories as universal structures. We first point out that the dipole picture of noncommutative geometry provides an intuitive argument for the robustness of the open Wilson lines and generalized star products therein. We calculate the one-loop effective action of noncommutative scalar field theory with a cubic self-interaction and show explicitly that the generalized star products arise in the nonplanar part. It is shown that, at the low-energy, large noncommutativity limit, the nonplanar part is expressible solely in terms of the scalar open Wilson line operator and descendants.
A Pilot Randomized Controlled Trial to Evaluate Isosorbide Mononitrate (IMN) Efficiency for Cervical Ripening Prior to Labor Induction in Iranian Pregnant Women

Our aim was to examine the effect and cost-effectiveness of isosorbide mononitrate (IMN) for outpatient (at home) cervical ripening in Iranian women with term pregnancy. Term pregnant women were randomly selected to receive either 15 mg vaginally administered IMN or placebo. Patients were advised to take the second dose at home 24 h later and return to the hospital for admission after the next 24 h if the onset of spontaneous contraction does not occur. Cervical status, maternal blood pressure, maternal pulse rate, fetal heart rate and various side effects were examined. IMN induced a significant increase in cervical Bishop Score; headache, nausea, and dizziness were seen in 8 of 28 participants of IMN group; although, all had normal vital signs and normal FHR, they had to be hospitalized and receive medication to relieve the unpleasant symptoms. Vaginal administration of 15 mg of IMN induced cervical ripening in term pregnant women. However, the administration of IMN for cervical ripening is not recommended as it produced headache in significant number of Iranian pregnant women.
Gas-Kinetic-Based Traffic Model Explaining Observed Hysteretic Phase Transition

Recently, hysteretic transitions to ``synchronized traffic'' with high values of both density and traffic flow were observed on German freeways [B. S. Kerner and H. Rehborn, Phys. Rev. Lett. 79, 4030 (1997)]. We propose a macroscopic traffic model based on a gas-kinetic approach that can explain this phase transition. The results suggest a general mechanism for the formation of probably the most common form of congested traffic.
Spectroscopic Discovery of Brown Dwarf-like Secondary Stars in the Cataclysmic Variables LL Andromedae and EF Eridani

Infrared spectroscopic observations of LL Andromedae and EF Eridani are presented. Our K-band spectrum of LL And reveals the presence of methane absorption in the secondary star indicating an effective temperature ≲1300 K, similar to a "T"-type methane brown dwarf. The secondary star in EF Eri is seen to be warmer with an effective temperature of ~1650 K and a spectroscopic classification consistent with an L4-5 star. Both secondaries have theoretical mass estimates of 0.04-0.055 M☉ (40-55 MJup). Our IR spectroscopic observations of LL And and EF Eri provide the first direct proof of the theoretical prediction that post-period minimum cataclysmic variables contain brown dwarf-like secondary stars.
Superficial Parasternal Intercostal Plane Blocks (SPIB) With Buprenorphine, Magnesium, and Bupivacaine for Management of Pain in Coronary Artery Bypass Grafting

Introduction Management of post-operative pain after cardiac surgery continues to be a challenge; inadequate management of pain can lead to increased morbidity, impaired physical function with potential delay in recovery, increased perioperative and chronic opioid consumption, increased cost of care, and a decreased quality of life. This study aimed to evaluate the effect of adding buprenorphine and magnesium to bupivacaine for superficial parasternal intercostal plane blocks (SPIB) on pain and opioid consumption in the first 24 hours after coronary artery bypass grafting (CABG). Methods Patients undergoing CABG were divided into the following four groups: saline SPIB, SPIB with bupivacaine (BPVC), SPIB with bupivacaine and buprenorphine (BPVC+BPRN), and SPIB with bupivacaine, buprenorphine, and magnesium (BPVC+BPRN+MG). The primary outcomes were pain scores and opioid consumption after SPIB; the secondary outcomes were post-operative nausea and vomiting, time to extubation, and length of stay (LOS) in the intensive care unit and hospital. Results One hundred thirty-four eligible patients undergoing CABG were randomized to either the saline (n=27), BPVC (n=20), BPVC+BPRN (n=24), or BPVC+BPRN+MG (n=29) group. All of the intervention groups combined (BPVC, BPVC+BPRN, and BPVC+BPRN+MG) had decreased pain scores and decreased opioid consumption when compared to the saline group; although not statistically significant, visual analog scale (VAS) scores trended downward at most time points with BPVC versus saline, BPVC+BPRN versus BPVC, and BPVC+BPRN+MG versus BPVC+BPRN. There was no difference among the study groups in the incidence of post-operative nausea and/or vomiting (PONV), time to extubation, hospital LOS, and ICU LOS. Conclusion In this prospective, double-blind, placebo-controlled trial, we found that SPIB with local anesthetic is effective at reducing VAS scores and opioid consumption after CABG. Further study is needed to determine whether the addition of adjuvants can further improve pain control and opioid consumption.

In agreementwith experimental studies, the semiconducting behavior for the studied compound, taking the effect of spinarrangement on symmetry into account, was obtained.DOI: 10.1103/PhysRevB.83. 085205 PACS number(s): 71
An Extremely Lithium-rich Bright Red Giant in the Globular Cluster M3

We have serendipitously discovered an extremely lithium-rich star on the red giant branch of the globular cluster M3 (NGC 5272). An echelle spectrum obtained with the Keck I High-Resolution Echelle Spectrograph reveals a Li I λ6707 resonance doublet of 520 mÅ equivalent width, and our analysis places the star among the most Li-rich giants known: log ϵ(Li) ≃ +3.0. We determine the elemental abundances of this star, IV-101, and three other cluster members of similar luminosity and color and conclude that IV-101 has abundance ratios typical of giants in M3 and M13 that have undergone significant mixing. We discuss mechanisms by which a low-mass star may be so enriched in Li, focusing on the mixing of material processed by the hydrogen-burning shell just below the convective envelope. While such enrichment could conceivably happen only rarely, it may in fact regularly occur during giant-branch evolution but be rarely detected because of rapid subsequent Li depletion.
Shocked POststarburst Galaxy Survey. III. The Ultraviolet Properties of SPOGs

The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify galaxies in the transitional phase between actively star-forming and quiescence with nebular lines that are excited from shocks rather than star formation processes. We explored the ultraviolet (UV) properties of objects with near-ultraviolet (NUV) and far-ultraviolet (FUV) photometry from archival GALEX data; 444 objects were detected in both bands, 365 in only the NUV, and 24 in only the FUV, for a total of 833 observed objects. We compared SPOGs to samples of star-forming galaxies (SFs), quiescent galaxies (Qs), classical E+A post-starburst galaxies, active galactic nuclei (AGN) host galaxies, and interacting galaxies. We found that SPOGs have a larger range in their FUV–NUV and NUV–r colors compared with most of the other samples, although all of our comparison samples occupied color space inside of the SPOGs region. On the basis of their UV colors, SPOGs are a heterogeneous group, possibly made up of a mixture of SFs, Qs, and/or AGN. Using Gaussian mixture models, we are able to recreate the distribution of FUV–NUV colors of SPOGs and E + A galaxies with different combinations of SFs, Qs, and AGN. We find that the UV colors of SPOGs require a >60% contribution from SFs, with either Qs or AGN representing the remaining contribution, while UV colors of E + A galaxies required a significantly lower fraction of SFs, supporting the idea that SPOGs are at an earlier point in their transition from quiescent to star-forming than E + A galaxies.
ARGO CMB Anisotropy Measurement Constraints on Open and Flat-Lambda CDM Cosmogonies

We use data from the ARGO cosmic microwave background (CMB) anisotropy experiment to constrain cosmogonies. We account for the ARGO beamwidth and calibration uncertainties, and marginalize over the offset removed from the data. Our derived amplitudes of the CMB anisotropy detected by the ARGO experiment are smaller than those derived previously. We consider open and spatially-flat-Lambda cold dark matter cosmogonies, with clustered-mass density parameter Omega_0 in the range 0.1-1, baryonic-mass density parameter Omega_B in the range (0.005-0.029)h^{-2}, and age of the universe t_0 in the range (10--20) Gyr. Marginalizing over all parameters but Omega_0, the ARGO data favors an open (spatially-flat-Lambda) model with Omega_0= 0.23 (0.1). However, these numerical values are model dependent. At the 2 sigma confidence level model normalizations deduced from the ARGO data are consistent with those drawn from the UCSB South Pole 1994, MAX 4+5, White Dish, and SuZIE data sets. The ARGO open model normalizations are also consistent with those deduced from the DMR data. However, for most spatially-flat-Lambda models the DMR normalizations are more than 2 sigma above the ARGO ones.
Bunching Coherent Curvature Radiation in Three-dimensional Magnetic Field Geometry: Application to Pulsars and Fast Radio Bursts

The extremely high brightness temperatures of pulsars and fast radio bursts (FRBs) require their radiation mechanisms to be coherent. Coherent curvature radiation from bunches has been long discussed as the mechanism for radio pulsars and recently for FRBs. Assuming that bunches are already generated in pulsar magnetospheres, we calculate the spectrum of coherent curvature radiation under a three-dimensional magnetic field geometry. Different from previous works assuming parallel trajectories and a monoenergetic energy distribution of electrons, we consider a bunch characterized by its length, curvature radius of the trajectory family, bunch opening angle, and electron energy distribution. We find that the curvature radiation spectra of the bunches are characterized by a multisegment broken power law, with the break frequencies depending on bunch properties and trajectory configuration. We also emphasize that in a pulsar magnetosphere, only the fluctuation of net charges with respect to the background (Goldreich–Julian) outflow can make a contribution to coherent radiation. We apply this model to constrain the observed spectra of pulsars and FRBs. For a typical pulsar ( , P = 0.1 s), a small fluctuation of the net charge δnGJ ∼ 0.1nGJ can provide the observable flux. For FRBs, the fluctuating net charge may be larger due to its abrupt nature. For δnGJ ∼ nGJ, a neutron star with a strong magnetic field and fast rotation is required to power an FRB in the spindown-powered model. The requirement is less stringent in the cosmic comb model thanks to the larger cross section and compressed charge density of the bunch made by the external astrophysical stream that combs the magnetosphere.
Performance of cashew (Anacardium occidentale) varieties under different planting density for growth and yield traits

Cashew (Anacardium occidentale L) is an important tropical tree crop revered for its economic and nutritional needs. The demand for cashew is increasing significantly in both domestic and international markets. Planting density and tree canopy influence the yield performances of tree crops. Planting of trees at higher densities in orchards offers high yield potential. In the current study, a field experiment was conducted to study the effect of planting density on growth and yield of different varieties of cashew during 2013-14 to 2017-18. The three varieties, viz. H-130, NRCC Sel. 2 and Bhaskara were planted at three different planting systems, viz. ultra density (2.5 × 2.5 m), high density (5.0 × 5.0 m) and normal density (7.5 × 7.5 m) and evaluated for growth and yield traits. The heading back was carried out in ultra density planting during the last week of May in all the years. The results revealed significant differences for yield and related traits among cashew varieties under different plant densities. The maximum yield was recorded in variety H-130 planted at 2.5 × 2.5 m spacing during second year (1248 kg/ha), third year (2234 kg/ha) and fourth (2432 kg/ha) year of planting and minimum (154 kg/ha) was observed in variety Bhaskara at 2.5 × 2.5 m spacing. The variety H-130 performed well in all the three different planting systems compare to NRCC Sel. 2 and Bhaskara due to positive response of pruning.
Hidden-strange molecular states and the 
Nϕ
 bound states via a QCD van der Waals force

In this work, we study the hidden-strange molecular states composed of a baryon and a vector meson in a coupled-channel $N\rho-N\omega-N\phi-\Lambda K^*-\Sigma K^*$ interaction. With the help of the effective Lagrangians which coupling constants are determined by the SU(3) symmetry, the interaction is constructed and inserted into the quasipotential Bethe-Salpeter equation to search for poles in the complex plane, which correspond to molecular states. Two poles are found with a spin parity $3/2^-$ near the $N\rho$ and the $\Sigma K^*$ thresholds, which can be related to the $N(1700)$ and the $N(2100)$, respectively. No pole near the $N\phi$ threshold can be found if direct interaction between a nucleon and $\phi$ meson is neglected according to the OZI rule. After introducing the QCD van der Waals force between a nucleon and $\phi$ meson, a narrow state can be produced near the $N\phi$ threshold. Inclusion of the QCD van der Waals force changes the line shape of the invariant mass spectrum in the $N\phi$ channel leading to a worse agreement with the present low-precision data. Future experiments at BelleII, JLab, and other facilities will be very helpful to clarify the existence of these possible hidden-strange molecular states.
Longitudinal fish species diversity and distribution in a medium-sized Afro-tropical river in the Lake Victoria Basin

Despite significantly influencing fisheries characteristics of major global basins, medium-sized rivers such as Awach Kibuon remain the least studied. This study evaluated longitudinal fish species diversity, distribution, and environmental influence in Awach Kibuon River, Lake Victoria Basin, Kenya, to inform sustainable management of fisheries resources within the region. Nine sites located in different zones of the river were sampled monthly for eight months in 2019 and 2020. Fish samples were collected for 45 minutes using a backpack electrofisher on a 50-m river reach in every sampling site. Selected physico-chemical parameters (pH, total dissolved solids (TDS), dissolved oxygen (DO), temperature, conductivity, and turbidity) were measured in situ using standard methods. Longitudinal river fish diversity was assessed using species richness, Simpson's Index (D), Shannon-Weiner Index (H′), and Pielou's Evenness Index (J). A total of 983 fish specimens belonging to 21 species, 12 genera, seven families, and six orders were caught during sampling. Cyprinidae was the most dominant family, represented by nine species, followed by Claridae, Mochokidae, and Cichlidae, represented by three species each. Longitudinal species richness, abundance, and diversity indices deviated from the expected downstream increase. Upstream stations had no fish, whereas midstream and river mouth stations had moderate and high species diversity, respectively. Pearson's correlation analyses showed that temperature, conductivity, TDS, depth, and velocity influenced fish species richness in the river. The above findings call for the inclusion of medium-sized rivers in fisheries management plans of Great Lakes Basins for sustainability.
THE FORMATION OF SECONDARY STELLAR GENERATIONS IN MASSIVE YOUNG STAR CLUSTERS FROM RAPIDLY COOLING SHOCKED STELLAR WINDS

We study a model of rapidly cooling shocked stellar winds in young massive clusters and estimate the circumstances under which secondary star formation, out of the reinserted winds from a first stellar generation (1G), is possible. We have used two implementations of the model: a highly idealized, computationally inexpensive, spherically symmetric semi-analytic model, and a complex, three-dimensional radiation-hydrodynamic, simulation; they are in a good mutual agreement. The results confirm our previous findings that, in a cluster with 1G mass 107 M⊙ and half-mass–radius 2.38 pc, the shocked stellar winds become thermally unstable, collapse into dense gaseous structures that partially accumulate inside the cluster, self-shield against ionizing stellar radiation, and form the second generation (2G) of stars. We have used the semi-analytic model to explore a subset of the parameter space covering a wide range of the observationally poorly constrained parameters: the heating efficiency, ηhe, and the mass loading, ηml. The results show that the fraction of the 1G stellar winds accumulating inside the cluster can be larger than 50% if ηhe ≲ 10%, which is suggested by the observations. Furthermore, for low ηhe, the model provides a self-consistent mechanism predicting 2G stars forming only in the central zones of the cluster. Finally, we have calculated the accumulated warm gas emission in the H30α recombination line, analyzed its velocity profile, and estimated its intensity for super star clusters in interacting galaxies NGC4038/9 (Antennae) showing that the warm gas should be detectable with ALMA.
