Floral micromorphological, palynological, and carpological characteristics of the rare endemic Korean species Peucedanum miroense (Apiaceae)

Peucedanum miroense K. Kim, H. ‐J. Suh & J.‐H. Song, recently reported as a new species endemic to South Korea, is distributed on mountains Duta‐san and Swinŭm‐san in Gangwon Province, South Korea. Given its conspicuously limited habitat range and small populations, this species qualifies as an endangered Red List species. In this study, we undertook a detailed investigation of the floral micromorphological, palynological, and carpological characters of P. miroense based on a range of microscopic analyses. Examination of the floral micromorphology of P. miroense revealed that the surface patterns of bractlets have potential utility in taxonomy studies of the genus Peucedanum. In addition, we established that this plant is characterized a papillose conical‐tabular rugose pattern of petal epidermal cells and bears sunken nectary slits on the stylopodium. Also identified were simple spherical orbicules bearing psilate surface ornamentation, as well as small tricolporate prolate to perprolate pollen grains characterized by verrucate and gemmate ornamentation. Moreover, we verified pollen wall stratification and presence of pollenkitt. The mericarps had colliculate‐striate surface patterns with trichomes and eight or nine vittae, and prismatic crystals were detected in different layers of the pericarp. We believe that the findings of this study will contribute to an evaluation of the taxonomic significance of this species within the genus Peucedanum, and also provide valuable information for the conservation of this rare endemic species.
THE EFFECT OF AGGREGATION ON PREDICTION IN AUTOREGRESSIVE INTEGRATED MOVING‐AVERAGE MODELS

Let xt be a time series generated by an autoregressive integrated moving‐average process ARIMA(p, d, q). The non‐overlapping aggregate series also follows an ARIMA process. Thus, the prediction of the aggregated observations could be done by either the disaggregate model or the aggregate model. We derive the efficiency of the predictors for two important disaggregate models, ARIMA(0, 1, 1) and ARIMA(0, 2, 2), when the models are assumed known. When the models are not known we estimate the efficiency through simulation with the models being selected using Akaike's information criterion.
Fluid viscosity determination by means of uncalibrated atomic force microscopy cantilevers

In this letter it has been proved that the vibrating resonance frequency of an atomic force microscope cantilever is strictly characterized by its thickness (α), while its width/thickness ratio (β) appears to be a less sensitive parameter that can be approximated to a constant. We therefore propose a data analysis method that, by accounting for a constant β, allows for the determination of the value of α and consequently to calculate η. This method of monitoring viscosity has the advantage of requiring short measurement times on very small sample volumes, thereby avoiding laborious, time-consuming cantilever calibration.
Dynamically generated pure spin current in single-layer graphene

The conductance mismatch problem limits the spin-injection efficiency significantly, and spin injection into graphene usually requires high-quality tunnel barriers to circumvent the conductance mismatch. We introduce an approach which enables the generation of pure spin current into single-layer graphene (SLG) that is free from electrical conductance mismatch by using dynamical spin injection. An experimental demonstration of spin-pumping-induced spin current generation and spin transport in SLG at room temperature was successfully achieved, and the spin coherence length was estimated to be 1.36 $\ensuremath{\mu}$m by using a conventional theoretical model based on the Landau-Lifshitz-Gilbert equation. The spin coherence length is proportional to the quality of SLG, which indicates that spin relaxation in SLG is governed by the Elliot-Yafet mechanism, as was reported.
How do young Saudi men prefer to receive fertility information? A population: Based survey in Al Kharj

Background and objectives: The factors that contribute to male infertility are poorly understood by men. Men's awareness of their own fertility has not been the subject of extensive research. Men are generally less aware of issues with fertility and reproductive health according to research on both men and women. Methods: Over the course of three months in 2022, a web-based survey on male fertility and reproductive health included a regionally representative sample of Saudi men in Al Kharj city. Men between the ages of 19 and 67 were included in the study. Results: There were 395 male volunteers with an average age of 25. Male infertility causes were listed by each participant and their understanding of fertility was assessed by two open ended questions and a comprehensive list of related risk factors and medical disorders. The general level of understanding of fertility remained consistent across most demographic parameters. Seventy percent of the males surveyed said they were familiar with male fertility and reproduction. Conclusion: Relatively few men learnt about fertility through doctors or the internet relative to television and radio.
Association of HLA-G 3′UTR Polymorphisms with Response to First-Line FOLFIRI Treatment in Metastatic Colorectal Cancer

Microenvironmental factors such as non-classical human leukocyte antigen-G (HLA-G) have been associated with cancer invasiveness and metastatic progression. HLA-G expression has been associated with specific single-nucleotide polymorphisms (SNP) in HLA-G 3′untranslated region (UTR) in several diseases. The primary aim was to investigate the predictive role of HLA-G polymorphisms on treatment efficacy in metastatic colorectal cancer (mCRC) patients homogeneously treated with first-line FOLFIRI (irinotecan, 5-fluorouracil, and leucovorin) and their association with soluble HLA-G (sHLA-G) plasma concentration. HLA-G 3′UTR was sequenced in 248 patients. A set of eight polymorphisms and related haplotypes were analyzed for their association with best tumor response, overall survival (OS), and progression-free survival (PFS). sHLA-G was measured by immunoassay in 35 available plasma samples and correlated with HLA-G 3′UTR polymorphisms/haplotypes. Our results showed that carriers of rs371194629 (+2960)-Ins allele were at risk for lack of complete response (hazard ratio (HR):0.29, pBH = 0.0336), while carriers of rs1710 (+3010)-G allele (rs1063320 (+3142)-C allele in linkage-disequilibrium), and rs9380142 (+3187)-G allele had a higher chance of complete response according to additive models (HR:4.58, pBH = 0.0245; HR:3.18, pBH = 0.0336, respectively). The combination of rs371194629-Del, rs1710-G, and rs9380142-G alleles forms the UTR1 haplotype. Patients who were carriers of UTR1/UTR-1 diplotype had a greater chance of complete response to therapy (HR:10.59, pBH = 0.0294). The same three beneficial alleles showed a trend toward higher pre-treatment sHLA-G plasma levels, supporting a functional role for polymorphisms in protein secretion. In conclusion, genetic variants of HLA-G are associated with treatment efficacy in mCRC patients treated with first-line FOLFIRI. This finding shed light on the combined effect of this immune system factor and chemotherapy in cancer patients.
Placental Transcriptome Profiling in Subtypes of Diabetic Pregnancies Is Strongly Confounded by Fetal Sex

The placenta is a temporary organ with a unique structure and function to ensure healthy fetal development. Placental dysfunction is involved in pre-eclampsia (PE), fetal growth restriction, preterm birth, and gestational diabetes mellitus (GDM). A diabetic state affects maternal and fetal health and may lead to functional alterations of placental metabolism, inflammation, hypoxia, and weight, amplifying the fetal stress. The placental molecular adaptations to the diabetic environment and the adaptive spatio–temporal consequences to elevated glucose or insulin are largely unknown (2). We aimed to identify gene expression signatures related to the diabetic placental pathology of placentas from women with diabetes mellitus. Human placenta samples (n = 77) consisting of healthy controls, women with either gestational diabetes mellitus (GDM), type 1 or type 2 diabetes, and women with GDM, type 1 or type 2 diabetes and superimposed PE were collected. Interestingly, gene expression differences quantified by total RNA sequencing were mainly driven by fetal sex rather than clinical diagnosis. Association of the principal components with a full set of clinical patient data identified fetal sex as the single main explanatory variable. Accordingly, placentas complicated by type 1 and type 2 diabetes showed only few differentially expressed genes, while possible effects of GDM and diabetic pregnancy complicated by PE were not identifiable in this cohort. We conclude that fetal sex has a prominent effect on the placental transcriptome, dominating and confounding gene expression signatures resulting from diabetes mellitus in settings of well-controlled diabetic disease. Our results support the notion of placenta as a sexual dimorphic organ.
Arctiini Leach, [1815] (Lepidoptera, Erebidae, Arctiinae) in a savanna areas of the Environmental Protection Area Alter do Chão, Santarém, Pará, Brazil

The richness and abundance of representatives of Arctiini (Lepidoptera: Erebidae: Arctiinae) was studied considering 88 representative points of savanna in the Alter do Chão Environmental Protection Area (APA), in the municipality of Santarém, state of Pará, Brazil. Moths were sampled monthly from December 2014 to December 2016 (except May 2015), with a light trap, Pennsylvania model, during a new moon night from 6:00 p.m. to 6:00 a.m. the following day. Abundance (N), richness (S) and diversity index (H’), Shannon uniformity (J’) index and Berger-Parker (BP) dominance were analyzed. Wealth estimators “Chao” (1st and 2nd order), “Jackknife” (1st and 2nd order) and “Bootstrap” were also used. A total of 1,375 specimens (N) belonging to 122 species (S) were captured. Idalusmulticolor (Rothschild, 1909) and Pheialateralis Klages, 1906 appear as new records for the Brazilian Amazon. The values for the analyzed parameters were H’= 3.25, J’= 0.67 and BP = 0.33. The estimators and “Bootstrap” (140) and “Jackknife 2nd order” (180) measured that between 14% and 33% of species can still be found, respectively, as shown by the species accumulation curve. The results of this study indicate changes in the faunal composition with an equivalent distribution of species between the Ctenuchina and Phaegopterina subtribes, quite different from anthropized and forested areas that present a predominance of Phaegopterina. In this way, the conservation of savanna fragments present in the APA Alter do Chão contributes to the maintenance of the local fauna and expands the knowledge of Arctiini in the Amazon.
Rationally injective modules for algebraic linear groups

1. Let G be an algebraic linear group over a field F. If G acts by linear automorphisms on some vector space M over F we say that M is a rational G-module if it is the sum of finite-dimensional G-stable subspaces V such that the representation of G on each V is a rational representation of G. The rational G-module M is said to be rationally injective if, whenever U is a rational G-module and q5 is a G-module homomorphism of a G-submodule V of U into M, 4) can be extended to a G-module homomorphism of U into M. This notion is basic for the cohomology theory of algebraic linear groups, as developed in [I1]. If K is a normal algebraic subgroup of G it is of interest to secure the spectral sequence relation between the cohomologies of G, K and G/K. In order to do this, one needs to know that a rationally injective rational G-module is cohomologically trivial as a K-module. Although this remains unsettled over arbitrary fields, we shall see here that an even stronger result holds over fields of characteristic 0. We shall also obtain convenient criteria for injectivity that are valid over arbitrary fields.
Enhancement of Anemia Detection by Correlating Computed Tomography Findings of Abdominal Aorta and Inferior Vena Cava With Laboratory Investigations

Anemia affects approximately a quarter of the global population, and improved detection may reduce the associated morbidity and mortality. This study investigated correlations between the results of laboratory hematological determinations of hemoglobin levels and attenuation values measured in the lumina of the abdominal aorta and inferior vena cava (IVC) via unenhanced computed tomography (CT) with the aim of expanding diagnostic options for anemia. The data of 423 patients who underwent abdominal unenhanced CT examinations and laboratory examinations at a tertiary hospital were retrospectively evaluated. CT data were collected using a standard abdominal protocol without contrast. The 151 patients who met the inclusion criteria were categorized by hemoglobin values as follows: <8 (severe anemia), 8-10.9 (moderate anemia), 10.9-12 (mild anemia in females), 10.9-13 (mild anemia in males), and >13 g/dL (non-anemic). The mean CT attenuation values in the aorta and IVC were 37.7 and 36.1 Hounsfield units (HU), respectively. A regression analysis performed to evaluate the correlation and predictability of hemoglobin-based aortic and IVC density yielded a coefficient of determination, R2: 0.42 (F ratio: 149.23, p < 0.0001). The highest contribution in the dependent variable (hemoglobin) was reported to IVC density, showing a significant positive correlation between hemoglobin and IVC density. Our study results demonstrate significant correlations between the densities of the aorta, IVC, and hemoglobin value. Accordingly, radiologists and clinicians can use these readily available values to facilitate diagnosis and patient care.
Comparison of Ferrous Sulphate Versus Iron Polymaltose Complex in the Treatment of Iron Deficiency Anemia in Children

Objective: To compare the efficacy of ferrous sulphate versus iron Polymaltose complex (IPC) in the treatment of iron deficiency anemia (IDA) in children. Study Design: Randomized controlled trial. Place and Duration: Department of Pediatrics, Combined Military Hospital, Kharian Pakistan from Jan 2019 to Mar 2020. Methodology: A total of 150 children with IDA were included. At baseline, blood sample was obtained for assessment of hemoglobin level. Then children were randomly divided in two groups. In Group-A (n=75), patients were given ferrous sulphate while in In Group-B (n=75), IPC was given. After 12-weeks of treatment, hemoglobin level was assessed. Efficacy was labeled as “yes” if there was 2 g/dl hemoglobin improvement. Results: In a total of 150 children, the mean age in Group-A was 6.56±2.33 years and 6.05±2.78 years in Group-B. In group A, there were 37 (49.3%) males and 38 (50.7%) females while in Group-B there were 35 (46.7%) males and 40 (53.3%) females. At baseline in group A, the mean hemoglobin level was 6.07±1.12 g/dl while in group B, it was 6.16±1.14 g/dl. After 12-weeks, in Group-A the mean hemoglobin level was 9.44±1.61 g/dl whereas in Group-B, it was 8.83±2.01 g/dl (p=0.0420). There was insignificant difference observed for efficacy in both groups (p-value = 0.051). Practical Implications: Both IPC and ferrous sulphate resulted in significant rise in hemoglobin levels but ferrous sulphate showed better results in comparison to IPC. Conclusion: Although in comparison to IPC, ferrous sulphate resulted in significantly better rise in hemoglobin levels among children with IDA, but overall efficacy between the two studied drugs was relatively similar. Keywords: Ferrous sulphate, iron Polymaltose complex, iron deficiency anemia.
Does reducing grazing pressure or predation conserve kowaris? A case study at Diamantina National Park

Abstract. Livestock contributes to the decline of many species in Australia. However, they may have less impact in arid environments, where annual plant species dominate. Kowaris (Dasyuroides byrnei), a small carnivorous marsupial, living on Diamantina National Park were monitored to assess the success of ecosystem recovery following a reduction in cattle. Kowaris were found at 10 locations within the study area: five where they had been recorded prior to the area becoming a national park and five ‘new’ locations. No kowaris were found at one of the historical sites. The density was estimated to range from 1 to 2.5 kowaris per square kilometre from 2007 to 2009. The results suggest that the population likely increased following a reduction in grazing pressure. However, a boom in rodents and predators occurred during the study with a corresponding decline in kowari detections. Kowaris have not been detected at any of the study sites since 2012. These results suggest that management of top-down factors as well as bottom-up factors are required to conserve kowaris. The work further highlights the need for replicated, long-term studies if the interactions between complex ecological processes, at a landscape scale, are to be understood so that threatened species, like the kowari, can be managed effectively.
Surgical treatment of severe adolescent idiopathic scoliosis through one-stage posterior-only approach: A systematic review and meta-analysis

The aim of this meta-analysis was to analyze the results of one-stage all-posterior spinal fusion for severe adolescent idiopathic scoliosis (AIS). A systematic search of articles about one-stage posterior spinal fusion for severe AIS was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data about population, pre-and postoperative radiographical data, surgical procedure details, and complications were extracted. Meta-analyses were performed when possible. Fourteen studies (640 patients) were included. The mean Cobb angle of the major curve varied from 80.0 ± 7.3 to 110.8 ± 12.1. The meta analysis showed a comprehensive coronal correction rate of the major curve of 58.6%, a comprehensive operative time of 274.5 min, and a comprehensive estimated intraoperative blood loss of 866.5 mL (95% confidence interval: 659.3–1073.6, I2 ≈ 0%). A total of 48 complications (5.4%) were reported. Overall, the meta-analysis showed a major complication rate of 4%. In seven cases, revision surgery was needed. Posterior-only approach is effective enough to correct severe curves and can spare the patient possible adverse events due to anterior approach. However, when choosing this approach for severe AIS, screw density needs to be high and posterior column osteotomies may need to be planned to mobilize the spine and maximize correction.
A Trajectory Method for the Optimization of the Multi-Facility Location Problem With lp Distances

We consider the multi-facility location problem of placing m new facilities optimally among n demand points (or existing facilities) so that the sum of all weighted lp distance pairs (facility to facility and facility to demand point) is minimized. A method involving the solution of differential equations by numerical integration is presented. This method is computationally comparable to many existing heuristic and iterative methods. It avoids the frequent convergence difficulties associated with many iterative methods for p > 1 and has no difficulties in dealing with Targe “clusters” of facilities of p = 1.
On Reducing the Outage Probability in VFD-NOMA With Limited CSI at Source

We study a virtual full-duplex (VFD) non-orthogonal-multiple-access (NOMA) system in which a source S transmits one message each to users R<sub>1</sub> and R<sub>2</sub>, and two messages to a destination D, in three time slots. In conventional VFD-NOMA, S follows a fixed sequence of transmission (SoT) for the messages of users and destination, leading to a higher outage probability (OP) at R<sub>2</sub> and D, and a higher overall system OP (O-OP). To this end, we propose a novel transmission scheme which significantly decreases the OP at R<sub>2</sub> and D, and the O-OP. We assume all the wireless links undergo Nakagami-<inline-formula> <tex-math notation="LaTeX">$ {m}$ </tex-math></inline-formula> fading, and S only knows the instantaneous channel state information (CSI) of S-R<sub>1</sub> and S-R<sub>2</sub> links. We assume users suffer from imperfect successive interference cancellation (I-SIC) and residual inter-user interference (R-IUI). We derive closed-form results for the OP and show it matches with the simulations. Comparison with half-duplex and full-duplex multiple access schemes is done to demonstrate efficacy of the improved VFD-NOMA.
Changing consumption behaviour towards immune-boosting food amidst
COVID- 19 outbreak: tracing the future trajectory

Businesses throughout the world have been affected by the coronavirus outbreak. Across countries and industries, small firms have suffered, and India is no different. While many enterprises were destroyed by the COVID-19 scenario, hundreds of others were able to cope. People are getting increasingly concerned about their physical and emotional health as the coronavirus pandemic spreads around the world. People's perspectives on life and what they value have altered. Consumers have been compelled to alter their routines as a result of the outbreak. People throughout the world are attempting to adapt to a new normal. Immune-Boosting foods have become the talk of the town amidst the pandemic. With this backdrop, the present study aimed to understand the demand for ImmuneBoosting foods and the factors that have contributed to the market for immune-boosting foods. The sample data for this study was collected using the purposive sampling technique. Statistical interventions using multiple linear regression and correlation were conducted to understand the relationship between various factors related to immuneboosting foods. The study revealed that the pandemic had increased the respondents’ inclination to purchase Immune-Boosting foods. Further, the inclination towards consumption of immune-boosting foods was influenced by independent variables like familiarity with immune-boosting foods, health consciousness, fear of contracting the disease, family testing COVID-19 positive, immune-boosting foods as a trending topic, Influence of social media, Frequent advertisements and offers, testimonials of others regarding Immune-Boosting foods. From the study, it can be inferred that the COVID-19 pandemic has laid a strong foundation for the future of immune-boosting foods.
The master bay plan problem: a solution method based on its connection to the three‐dimensional bin packing problem

This paper addresses the problem of determining stowage plans for containers in a ship, referred to as the Master Bay Plan Problem (MBPP). MBPP is NP-complete. We present a heuristic method for solving MBPP based on its relation with the three-dimensional bin packing problem (3D-BPP), where items are containers and bins are different portions of the ship. Our aim is to find stowage plans, taking into account structural and operational constraints related to both the containers and the ship, that minimize the time required for loading all containers on board. A validation of the proposed approach with some test cases is given. The results of real instances of the problem involving more than 1400 containers show the effectiveness of the proposed approach for large scale applications.
