Association Between Vitamin D and Minor Salivary Gland Inflammation

Objective There has been increasing research regarding the effects of vitamin D on autoimmune disorders. There is some evidence of a correlation between vitamin D levels and sicca symptoms. We attempted to evaluate the correlation between vitamin D levels and inflammation of the minor salivary gland (MSG). Methods Data for 214 patients who had undergone MSG biopsy were reviewed. Eighteen patients with other autoimmune/neoplastic processes were excluded. Seventy-seven of 196 patients had serum Vitamin D levels available and were selected for this retrospective study. Demographic, clinical, and immunological features, extra-glandular manifestations, autoantibodies, and clinical laboratory tests were collected and compared between patient groups with a focus score (FS) of 0 and 1 or more. Results Out of 77, 29 patients had an FS of 0 while 48 had an FS of 1 or more. Mean vitamin D levels were noted to be lower in patients with an FS of 1 when compared to patients with an FS of 1 or more. Conclusion In this study, patients with an FS of 1 were noted to have low vitamin D levels but this association was not seen at a higher FS.
Lilium Cultivars and Flowering Behavior

Flowering behavior and flowering response of different Lilium genotypes was carried out during year 2018 at Division of Floriculture and Landscape Architecture SKUAST- K Shalimar. 15 cultivars including Navona , Malesco, Litouwen, Black Out, Revenna, Pink Palace, Tiber, Conca-D, Nello, Yellow Diamond, Tresor, Rialto, Courier, Cobra, and were evaluated on the basis of floral biology and flowering behavior. The outcome of the results revealed those maximum days to bud appearance after planting 44.48 days was recorded with cultivar Tiber where as minimum days 40.55 resulted with cultivar Black Out. Highest values for Bud diameter at maturity 26.59 mm was observed with cultivar Black Out and lowest values 18.87 mm with cultivar Navona. Bud length ranged 5.30 cm to 9.08 cm with cultivars Navona and Black Out, respectively. Number of florets per spike ranged minimum 2.36 to maximum 6.10 with cultivar Navano and Blackout respectively. Similar trend was followed for minimum to maximum values for floret diameter, inflorescence length and inflorescence diameter.
FREE VIBRATION OF LINE SUPPORTED RECTANGULAR PLATES USING A SET OF STATIC BEAM FUNCTIONS

The free vibration of thin orthotropic rectangular plates, which may be continuous over a number of intermediate line supports in one or two directions, is analyzed by the Rayleigh-Ritz method. A new set of admissible functions which are the static solutions of a point supported beam under a series of sine loads is developed. The eigenfrequency equation for the plate is derived by minimizing the potential energy. A very simple and general computer programme has been compiled. The basic concept to form the set of static beam functions is very clear and requires no complicated mathematical knowledge. Some numerical results presented are compared with those obtained by other numerical methods in the literature. It is shown that this set of static beam functions has some advantages in terms of computational cost, application versatility and numerical accuracy, especially for the plate problem with a large number of intermediate line supports and/or when higher vibrating modes need to be calculated.
Extremal properties of Synge’s world function and discrete geometry

Properties of σ space [a set Ω of points P with a real function σ(P,P’) given on Ω] are investigated. A continuity of the set Ω is not necessary and, generally, geometry is discrete. The properties of the world function σ are investigated. At certain (extremal) world function properties the σ space is shown to be a subset of points of Euclidean space or Riemannian space. The presented approach has the peculiarity that no operation other than the function σ is given on σ space. In particular, all such operations as linear operation over vectors, constructing lines and planes, and dimension of the space are expressed through the world function σ and only through it (if it is extremal). A violation of the σ‐space extremality leads to going out beyond the frames of Riemannian geometry (lines are substituted by tubes of lines, etc.). The presented approach can be useful in quantum gravitation, string models, and other problems, where the properties of the event space at small distances are important.
ISOTOPE EFFECT IN THE DISSOCIATIVE ATTACHMENT IN H2 AT LOW ENERGY.

Abstract : The dissociative attachment cross section for formation of H- and D- from H2, HD, and D2 was measured in the threshold range from 3.75 to 5 eV using a mass spectrometer for ion identification. A pronounced isotope effect is observed. The cross section of H- from H2 has a peak value of 1.6 x 10 to the -21 power sq. cm, D- from HD, 1 x 10 to the -22 power sq. cm, and D- from D2, 8 x 10 to the -24 power sq. cm, all peaks occurring at 3.75 eV. Negative ion formation in this energy range proceeds via the compound state, doublet-Sigma + sub u, whose lifetime against autodetachment is calculated from the above cross sections to be about 1 x 10 to the -15 power sec. Because of this short lifetime and the relatively long time needed for the atoms to separate, the probability of survival of the negative ion and therefore the dissociative attachment cross section in H2 at 3.75 eV is small. For the heavier isotopes the separation time is even longer and therefore the dissociative attachment cross section is minute. The same compound state is also responsible for vibrational excitation of the hydrogen molecule. (Author)
Germinal Center-Derived Diffuse Large B-cell Lymphomas with Aberrant Co-expression of MUM1 in Adults and Children

The aim of this study is to analyze the clinical and pathological features of germinal center (GC)- derived diffuse large B-cell lymphomas (DLBCL) with aberrant co-expression of MUM1 and to further analyze the differences between adults and pediatric populations. Clinical and pathological data of 32 cases of GC-derived DLBCL with aberrant co-expression of MUM1 were reviewed and analyzed. Thirty-two cases were categorized into pediatric (n=12) and adult (n=20) groups. GC-derived DLBCL with aberrant co-expression of MUM1 was found to manifest a wide age range, extensive involvement sites, different histopathological distribution, and complex clinical presentations. Compared to adults, pediatric patients showed a significantly higher frequency of Waldeyer's ring (WR) involvement ( P =0.008), higher frequency of stage II ( P =0.035), and lower incidence of fatality ( P =0.014). Among the 32 cases, lymphomas were frequently involved in WR, followed by the gastrointestinal tract, lymph nodes, and bone marrow. Pediatric patients showed a significantly higher frequency of WR involvement than adult patients ( P =0.008). Lymphomas involving WR in adults showed similar localized clinical stages, excellent outcomes, and pathological features compared to the disease in the pediatric population. Lymphomas involving the gastrointestinal tract in adults shared clinical features with the disease in children but with high P53 positive expression. GC-derived DLBCL with aberrant co-expression of MUM1 in adults is clinically more heterogeneous than children. Tumors involving WR in adults share many similarities to their pediatric counterparts.
CHARACTERIZATION OF A TEMPERATURE-SENSITIVE MAGNETIC FLUID

A temperature-sensitive magnetic fluid with a low Curie temperature is synthesized. The fluid is characterized by x-ray diffraction, magnetization, and small angle neutron scattering (SANS). Low Curie temperature of the fluid enables us to separate out the nuclear and magnetic scattering contributions in SANS by recording the SANS pattern at two temperatures.
Dynamic models of long-memory processes driven by Lévy noise

A class of continuous-time models is developed for modelling data with heavy tails and long-range dependence. These models are based on the Green function solutions of fractional differential equations driven by Lévy noise. Some exact results on the second- and higher-order characteristics of the equations are obtained. Applications to stochastic volatility of asset prices and macroeconomics are provided.
Creeping Flow Through an Axisymmetric Sudden Contraction or Expansion

Creeping flow through a sudden contraction/expansion in an axisymmetric pipe is studied. Sampson's solution for flow through a circular orifice in an infinite wall is used to derive an approximation for the excess pressure drop due to a sudden contraction/ expansion in a pipe with a finite expansion ratio. The accuracy of this approximation obtained is verified by comparing its results to finite-element simulations and other previous numerical studies. The result can also be extended to a thin annular obstacle in a circular pipe
Influence of film width and magnetic field orientation on AC loss in YBCO thin film

Three YBCO thin films on sapphire substrate with widths of 3, 5, and 10 mm were prepared, and their AC loss characteristics were studied experimentally. The total AC loss dissipated in samples carrying AC transport current in an AC transverse magnetic field was measured by an electromagnetic method. The total AC loss in YBCO film is proportional to the film width and the perpendicular magnetic field component, a component of the transverse magnetic field that is perpendicular to the film wide face. Reduction of the film width and/or the perpendicular magnetic field component is an essential means of decreasing the total AC loss. When plotting the total AC loss divided by film width against the perpendicular magnetic field component, curves for various film widths and field angles almost agree with each other. The total AC loss can be estimated by analytical expressions except in an intermediate range of the perpendicular magnetic field component. The experimental results indicate two engineering approaches for reducing the total AC loss in YBCO film: decreasing the film width and decreasing the perpendicular magnetic field component. Findings have shown empirically that decreasing the film width and decreasing sinα, where α is the field angle, are equivalently effective in reducing the total AC loss.
UCP2 as a Cancer Target through Energy Metabolism and Oxidative Stress Control

Despite numerous therapies, cancer remains one of the leading causes of death worldwide due to the lack of markers for early detection and response to treatment in many patients. Technological advances in tumor screening and renewed interest in energy metabolism have allowed us to identify new cellular players in order to develop personalized treatments. Among the metabolic actors, the mitochondrial transporter uncoupling protein 2 (UCP2), whose expression is increased in many cancers, has been identified as an interesting target in tumor metabolic reprogramming. Over the past decade, a better understanding of its biochemical and physiological functions has established a role for UCP2 in (1) protecting cells from oxidative stress, (2) regulating tumor progression through changes in glycolytic, oxidative and calcium metabolism, and (3) increasing antitumor immunity in the tumor microenvironment to limit cancer development. With these pleiotropic roles, UCP2 can be considered as a potential tumor biomarker that may be interesting to target positively or negatively, depending on the type, metabolic status and stage of tumors, in combination with conventional chemotherapy or immunotherapy to control tumor development and increase response to treatment. This review provides an overview of the latest published science linking mitochondrial UCP2 activity to the tumor context.
Computer Self-efficacy and Perceptions of Online Learning during the Covid-19 Lockdown in Iran High Schools

The sudden shift to online teaching following the outbreak of COVID-19 has confronted English language learners with numerous challenges. The students’ perceptions and practices in online learning environments might be influenced by their technology-oriented abilities to survive in the current educational predicament. The current study elucidated the 12th-grade high school students’ online learning experiences in a developing country during the global pandemic in light of their computer self-efficacy (CSE) level. To this end, a total number of 110 students completed the computer self-efficacy scale. The results indicated a moderate to low level of computer self-efficacy among the participants. According to the obtained scores, they were divided into low-CSE and high-CSE groups and asked to ruminate over their online learning experiences during the pandemic by answering eight questions in the form of self-reflection essays. The self-reflections of the two groups were separately analysed, and the recurrent themes were extracted. The results revealed several commonalities and discrepancies between the low- and high- CSE students considering their distant learning experiences within the COVID-19 lockdown. The findings provide pedagogical recommendations for enhancing online learning efficiency among high school students.
The Effect of pH to The Interaction between Folic Acid and Folate Receptor Alpha: Molecular Dynamics Study

ancer is one of the major health problems in the world. Early detection using Magnetic Resonance Imaging (MRI) for the presence of cancer cells could improve the successful rate of treatment. For this reason, a selective contrast agent is required to improve the accuracy of cancer diagnosis. Many cancer cells overexpress the folate receptor alpha (FRA) on its surface. Therefore
Crosstalk between microRNA and Oxidative Stress in Heart Failure: A Systematic Review

Heart failure is defined as a clinical syndrome consisting of key symptoms and is due to a structural and/or functional alteration of the heart that results in increased intracardiac pressures and/or inadequate cardiac output at rest and/or during exercise. One of the key mechanisms determining myocardial dysfunction in heart failure is oxidative stress. MicroRNAs (miRNAs, miRs) are short, endogenous, conserved, single-stranded non-coding RNAs of around 21–25 nucleotides in length that act as regulators of multiple processes. A systematic review following the PRISMA guidelines was performed on the evidence on the interplay between microRNA and oxidative stress in heart failure. A search of Pubmed, Embase, Scopus, and Scopus direct databases using the following search terms: ‘heart failure’ AND ‘oxidative stress’ AND ‘microRNA’ or ‘heart failure’ AND ‘oxidative stress’ AND ‘miRNA’ was conducted and resulted in 464 articles. Out of them, 15 full text articles were eligible for inclusion in the qualitative analysis. Multiple microRNAs are involved in the processes associated with oxidative stress leading to heart failure development including mitochondrial integrity and function, antioxidant defense, iron overload, ferroptosis, and survival pathways.

The global situation is causing a crisis in the mental health of the population in general as a result of the coronavirus pandemic, and the person in situations of crisis or change, present responses of anxiety, stress, and depression due to the moments of risk that are being faced as a result of the pandemic. Therefore, its research objective is to determine depression, anxiety, and stress in residents of a neglected population in San Juan de Lurigancho. It is a quantitative, descriptive, cross-sectional study, with a total population of 480 participants from the district of San Juan de Lurigancho, who responded to a sociodemographic data questionnaire and the Depression, Anxiety, and Stress Scale (DASS-21). In the results, we observe the correlation between the main variable depression with the variables of sociodemographic aspects in the study, it can be evidenced that there is an existing relationship between the main variable depression, and the variables of the sociodemographic aspects since its score is (p <0.005). In conclusion, professional help for young people should be taken into account, promoting prevention programs, coping skills, and mental health about the pandemic and what decisions to make in this current situation.
Squeeze flow magnetorheology

This paper is concerned with an investigation of the rheological performance of magnetorheological fluids under squeeze flow. Preliminary results on Newtonian fluids are first compared to Stefan’s equation. Then, unidirectional monotonic compression tests are carried out in the presence of uniaxial external magnetic fields at slow compression rates under constant volume operation. Results are compared to Bingham plastic, biviscous, and single chain micromechanical squeeze flow models. Measurements using combined deformation modes (compression+small-strain oscillatory shear) suggest a compression-induced shear strengthen effect up to strains of ∼0.5. Particle-level dynamic simulations are in qualitatively good agreement with experimental observations.
Congested Period in Professional Youth Soccer Players Showed a Different High Decelerations Profile in the Group Performance and a Specific Positional Behaviour

Present soccer demands are increasing in terms of running requirements and the number of matches until youth soccer players experience several periods of fixture congestion during the season. Currently, congested periods have not been extensively studied in this population. For this reason, this study aimed to compare the running demands of professional youth soccer players in congested periods according to their specific playing positions. Twenty youth players were grouped according to their position: Central Defenders (CD), Fullbacks (FB), Midfielders (MF), Wide Midfielders (WM) and Strikers (ST). A GPS system was used to monitor the players during the first (M1), second (M2) and third (M3) matches played during a congested period, measuring their total distance covered (TDC), DC 18.0–20.9 km·h−1, DC 21.0–23.9 km·h−1, DC > 24.0 km·h−1, number of high accelerations (>2.5 m·s−2), number of high decelerations (<2.5 m·s−2) and peak speed (km·h−1). M1, M2 and M3 showed the same TDC, DC 18.0–20.9 km·h−1, DC 21.0–23.9 km·h−1, DC > 24.0 km·h−1, number of high accelerations, and peak speed (p > 0.05). The statistical analysis showed significant differences between M1, M2 and M3 in the decelerations recorded between M1 and M3 (p < 0.05). Likewise, each position showed specific behaviours during the congested period, with all showing at least one difference in DC 18.0–20.9 km·h−1, 21.0–23.9 km·h−1 or >24.0 km·h−1 between M1, M2 and M3 (p < 0.05). In conclusion, coaches should pay attention to the fatigue produced by the number of high decelerations. Secondly, an individualized training protocol should be considered according to the running requirements of each position when youth professional soccer players are involved in a congested period.
FERMIGAMMA-RAY SPACE TELESCOPE OBSERVATIONS OF THE GAMMA-RAY OUTBURST FROM 3C454.3 IN NOVEMBER 2010

The flat-spectrum radio quasar 3C454.3 underwent an extraordinary 5 day γ-ray outburst in 2010 November when the daily flux measured with the Fermi Large Area Telescope (LAT) at photon energies E > 100 MeV reached (66 ± 2) × 10−6 photons cm−2 s−1. This is a factor of three higher than its previous maximum flux recorded in 2009 December and ≳ 5 times brighter than the Vela pulsar, which is normally the brightest source in the γ-ray sky. The 3 hr peak flux was (85 ± 5)×10−6 photons cm−2 s−1, corresponding to an apparent isotropic luminosity of (2.1 ± 0.2)×1050 erg s−1, the highest ever recorded for a blazar. In this Letter, we investigate the features of this exceptional event in the γ-ray band of the Fermi-LAT. In contrast to previous flares of the same source observed with the Fermi-LAT, clear spectral changes are observed during the flare.
How Conditions and Resources Connected to Digital Management Systems and Remote Work Are Associated with Sustainable Work

The current state of work–life transformation will see more white-collar work being performed remotely using digital management systems. There is, however, a lack of research on factors and resources contributing to sustainable work when working remotely using digital management systems. The aim of this study was to study the conditions and resources connected to digital management systems and remote work, and their associations with sustainable work, in terms of process quality, trust, and sense of coherence, when working remotely during the COVID-19 pandemic. An analytical cross-sectional study was performed. Questionnaire data from white-collar employees (n = 484) in two private companies were analyzed with regression models, focusing on the importance of the conditions and resources connected to digital management systems and remote work, stratified by working from home or at the office. The results showed digital conditions and resources being associated with indicators of sustainable work. Furthermore, the results showed that social work relations were additional important explanatory factors for sustainable remote work. This study contributes to the development of a new post-pandemic work–life balance by concluding that sustainable remote work needs to be ensured by functional digital management systems and adequate leadership supporting the development of a positive team and learning climate.
Electromagnetic cyclotron-loss-cone instability associated with weakly relativistic electrons

The amplification of fast extraordinary mode waves with frequencies very close to the electron cyclotron frequency is investigated for a plasma which consists of a weakly relativistic electron component with a loss-cone type distribution and a cold background electron component. The basic mechanism of the amplification is attributed to a relativistic cyclotron resonance between the wave and the energetic electrons. The method employed in the present analysis enables us to solve the dispersion relation in a self-consistent manner for arbitrary ratio of the densities of the energetic and background electrons. It is found that the maximum growth rates occur at certain values of ω2pe/Ω2e and the angular dependence of the growth rate is sensitive to the ratios ω2pe/Ω2e and ne/nb. Here ωpe and Ωe are the electron plasma frequency and the electron cyclotron frequency, respectively, and ne and nb denote the number densities of the energetic and background electrons, respectively.
The age of the old Magellanic Cloud clusters — II. NGC 1786, 1841 and 2210 as evidence for an old coeval population of LMC and galactic globular clusters

We present new, deep (V, V -I) colour-magnitude diagrams (CMDs) for the three old, metal-poor Magellanic Cloud (MC) clusters: NGC 1786, 1841 and 2210. The photometry reaches V ~ 24 mag, yielding the first insight into the tum-off region and the upper main sequence of these clusters. On the basis of these new data, we found that the three clusters have quite similar CMDs, which closely resemble that of the metal-poor Galactic globular M68. Our main conclusion is that the most metal-poor clusters in the MC have not only similar metallicity to, but are also of age comparable with the metal-poor globulars in the Galaxy. Considering the observational uncertainties we estimate the relative age difference uncertainty is ",20 per cent (Le. 3 Gyr). This evidence suggests an evolutionary scenario in which the production of globular clusters started in a similar way in the two galaxies, whilst more metal-rich clusters show evidence of a different evolution, as proved by the occurrence in the Large Magellanic Cloud (LMC) of clusters which are actually intermediate between the two galactic Oosterhoff types.
