Bacterial conjunctivitis: microbiological profile and molecular characterization of Methicillin-Resistant Staphylococci isolated from Minia governorate, Egypt

Ocular infections caused by bacterial sources are a global health issue that can damage the construction of the eye, and lead to disability. The goals of this study were to look at the bacterial species causing conjunctivitis, as well as their antibacterial susceptibility patterns. In addition to emphasizing on detecting the predominance of certain virulence genes of Methicillin Resistant Staphylococcus aureus (MRSA), and Methicillin Resistant coagulase negative Staphylococci (MR-CoNS), which are known to cause conjunctivitis. In this study, several swabs of bacterial conjunctivitis were sampled from patients who attended to the Ophthalmology department, Minia University and Malawi Ophthalmology hospital, Egypt. A total of 200 eye swab samples were analyzed over the entire period of the study. Results showed that about 133 eye swab samples expressed growth of about 147 pathogenic bacterial spp. The predominant isolated bacteria were Staphylococcus aureus (44.89 %), followed by Coagulase negative Staphylococci (29.9 %). On the contrary, Esherichia coli , Pseudomonas aeruginosa , Proteus sp. , Streptococcus pneumonia , Klebsiella sp. , and Haemophilus influenza e, were the least detected bacterial spp. Most of the bacterial isolates tested in this study exhibited high resistance to Amoxacillin-Clavulanic, Sulfamethoxazole-trimethoprim, Cefotaxime, and Cefoperazone. Using Cefoxitin, results of the phenotypic test predicted that 40.9 % of the Staphylococcal spp. were MRSA, and 23.6 % were MR-CoNS. The Polymerase chain reaction (PCR) technique was used to explore the presence of several bacterial pathogenicity genes, including MecA , PVL , icaA , icaD , and Hla in the MRSA and in MRCoNS. Results of the PCR revealed that all MRSA and MR-CoNS had MecA , icaA , and icaD genes, whereas 28.9 % of the MRSA had PVL and Hla . However, no isolate of MR-CoNS recorded the presence of the PVL or HLa genes. This study showed that prevalence of the bacterial eye conjunctivitis has increased with MRSA dominance. All the MRSA possessed at least the icaA , and icaD virulence genes beside the MecA gene, which confirm their roles in the pathogenesis of conjunctivitis.

The recent capture of Bregmaceros nectabanus (Bregmacerotidae) from purse-seine fishery in Izmir Bay, NE Aegean Sea

On 25 March 2022, two specimens of Bregmaceros nectabanus were captured by a commercial purse-seiner for targeting sardine and anchovy off Kırdeniz, Izmir Bay at a depth of 30 m. The total length of these specimens was between 53 and 63 mm. Thus, the record number has reached at least 37 specimens in the eastern Mediterranean Sea. This paper presents the third confirmed record of B. nectabanus from Izmir Bay (Northeastern Aegean Sea). Though the sporadic occurrences of this species in Izmir Bay do not indicate an established population for the time being, it signs that it's getting abundant.
Declined peat heterotrophic respiration as consequences from zeolite amendment simulation: coupling descriptive and predictive modelling approaches

Nowadays, halting greenhouse gasses (GHG) emission is the world's major concern to mitigate global climate change. In oil palm cultivated tropical peatland, GHG emission is primarily constituted of CO2 flux emitted from aerobic heterotrophic respiration (Rh), the natural degradation process of organic material in an oxidative environment. By coupling descriptive and predictive statistical approaches, this study attempt to gain an in-depth understanding of the effects of zeolite rates and incubation time on CO2 emission that came from aerobic Rh in peat, as well as their decomposition process. This study found that zeolite amelioration up to 30% of the peat at field capacity and starting from the first month of observation (month-1) significantly restricted peat Rh, denoted by a reduced amount of observed CO2 flux (0.021 and 0.019-0.012 mg m-2 sec-1, respectively). Both factors and several soil variables exhibited some non-linear relationships with Rh at different magnitudes and importance, showing the limitation of the traditional linear-based approach to interpreting their complex interrelationships, as well as predicting CO2 flux. This study highlights the vital role of a polynomial (GAM) and artificial intelligence (Cubist and GBM) -based pedotransfer models in improving our understanding regarding the dynamic of the peat decomposition process as affected by zeolite amendment.
Chromospheric evaporation flows and density changes deduced from Hinode/EIS during an M1.6 flare

We analyzed high-cadence sit-and-stare observations acquired with the Hinode/EIS spectrometer and HXR measurements acquired with RHESSI during an M-class flare. During the flare impulsive phase, we observe no significant flows in the cooler Fe XIII line but strong upflows, up to 80-150 km/s, in the hotter Fe XVI line. The largest Doppler shifts observed in the Fe XVI line were co-temporal with the sharp intensity peak. The electron density obtained from a Fe XIII line pair ratio exhibited fast increase (within two minutes) from the pre-flare level of 5.01x10^(9) cm^(-3) to 3.16x10^(10) cm^(-3) during the flare peak. The nonthermal energy flux density deposited from the coronal acceleration site to the lower atmospheric layers during the flare peak was found to be 1.34x10^(10) erg/s/cm^(2) for a low-energy cut-off that was estimated to be 16 keV. During the decline flare phase, we found a secondary intensity and density peak of lower amplitude that was preceded by upflows of 15 km/s that were detected in both lines. The flare was also accompanied by a filament eruption that was partly captured by the EIS observations. We derived Doppler velocities of 250-300 km/s for the upflowing filament material.The spectroscopic results for the flare peak are consistent with the scenario of explosive chromospheric evaporation, although a comparatively low value of the nonthermal energy flux density was determined for this phase of the flare. This outcome is discussed in the context of recent hydrodynamic simulations. It provides observational evidence that the response of the atmospheric plasma strongly depends on the properties of the electron beams responsible for the heating, in particular the steepness of the energy distribution.
SOLAR WIND CHARGE EXCHANGE CONTRIBUTION TO THE ROSAT ALL SKY SURVEY MAPS

DXL (Diffuse X-ray emission from the Local Galaxy) is a sounding rocket mission designed to estimate the contribution of solar wind charge eXchange (SWCX) to the diffuse X-ray background and to help determine the properties of the Local Hot Bubble. The detectors are large area thin-window proportional counters with a spectral response that is similar to that of the PSPC used in the ROSAT All Sky Survey (RASS). A direct comparison of DXL and RASS data for the same part of the sky viewed from quite different vantage points in the solar system, and the assumption of approximate isotropy for the solar wind, allowed us to quantify the SWCX contribution to all six RASS bands (R1–R7, excluding R3). We find that the SWCX contribution at , where the DXL path crosses the Galactic plane, is for R1, for R2, for R4, for R5, and negligible for the R6 and R7 bands. Reliable models for the distribution of neutral H and He in the solar system permit estimation of the contribution of interplanetary SWCX emission over the the whole sky and correction of the RASS maps. We find that the average SWCX contribution in the whole sky is for R1, for R2, for R4, for R5, and negligible for R6 and R7.
Antibacterial potential of different red seaweed (Rhodophyta) extracts against ornamental fish pathogen Salmonella arizonae

This study evaluated the antibacterial effects of different red seaweed (Kappaphycus striatus, Eucheuma denticulatum, Hydropuntia edulis) against Salmonella arizonae that caused disease in goldfish Carassius auratus. In vitro antibacterial susceptibility was determined using a standard disc diffusion assay. Further in vivo experiments were conducted on seaweeds with the highest zone of inhibition. Results showed that K. striatus had the highest zone of inhibition with 30.9 ±0.62 mm followed by H. edulis (29.6 ±1.61 mm), and E. denticulatum (27.6 ±0.51 mm). Promisingly, the antibacterial activity of seaweeds tested was comparable with that of cefixime, trimethoprim, and novobiocin and was significantly higher than the other seven antibiotics tested in this study. Moreover, the in vivo treatment of K. striatus to S. arizonae challenged C. auratus significantly decreased the mortality; the positive control group attained 100% mortality while the treated group had 40% mortality after 10 days of post-infection. This study showed the potential use of K. striatus to control S. arizonae infection in aquarium fishes.
Assessment of risk factors in corona virus 19 infected persons

Background: Mortality caused by Covid-19 is more in individuals suffering chronic diseases. Aim of The Work: To detect if there is any predictor for severe illness in patients with COVID-19 diseases. Patients and Methods: This retrospective study included 200 cases suffering from COVID-19 pneumonia admitted to Damanhour chest diseases hospital . The patients had been divided into two groups; the first one had 100 patients (30 men & 70 women) who had manifestations of pneumonia on radiological examination and had risk factors; the second group included 100 controls (53 men & 47 women) who had pneumonia manifestations on radiological examination with no risk factors. Mild Covid-19 cases with no radiological signs of pneumonia as well as pediatric cases were excluded. For all included individuals, a detailed history, clinical examination, COVID19 detection by PCR, arterial blood gases, CBC, liver function tests, blood urea and serum Creatinine , CRP, D-dimer serum ferritin, and CT chest were performed. Results: Most common comorbid conditions were systemic hypertension (62%), DM (61%), and IHD (48%)). SpO2 below 74% was found to be significantly predictive of invasive respiratory assistance or in-hospital mortality in older age groups; risk factors included myalgia (22%), chest pain, and DCL manifestations (11%). D-dimer identified as an independent risk factor (P value 0.034), serum Cr in the 1st group was higher in comparison with the 2nd group. Conclusion: Advanced age was more vulnerable to infection with COVID-19. Hypertension, DM and IHD were independently accompanied by a higher risk of in-hospital mortality. COVID19 infected cases with risk factors had poor outcomes. Chronic patients had decreased blood O2 saturation.
An isolated compact galaxy triplet

We report the discovery of an isolated compact galaxy triplet SDSS J084843.45+164417.3, which is first detected by the LAMOST spectral survey and then confirmed by a spectroscopic observation of the BFOSC mounted on the 2.16 meter telescope located at Xinglong Station, which is administered by National Astronomical Observatories, Chinese Academy of Sciences. It is found that this triplet is an isolated and extremely compact system, which has an aligned configuration and very small radial velocity dispersion. The member galaxies have similar colors and show marginal star formation activities. These results support the opinion that the compact triplets are well-evolved systems rather than hierarchically forming structures. This serendipitous discovery reveals the limitations of fiber spectral redshift surveys in studying such a compact system, and demonstrates the necessity of additional observations to complete the current redshift sample.

The Quench Action

We give a pedagogical introduction to the methodology of the Quench Action, which is an effective representation for the calculation of time-dependent expectation values of physical operators following a generic out-of-equilibrium state preparation protocol (for example a quantum quench). The representation, originally introduced in Caux and Essler (2013 Phys. Rev. Lett. 110 257203), is founded on a mixture of exact data for overlaps together with variational reasonings. It is argued to be quite generally valid and thermodynamically exact for arbitrary times after the quench (from short times all the way up to the steady state), and applicable to a wide class of physically relevant observables. Here, we introduce the method and its language, give an overview of some recent results, suggest a roadmap and offer some perspectives on possible future research directions.
EFFECTS OF STRONG GRAVITATIONAL LENSING ON MILLIMETER-WAVE GALAXY NUMBER COUNTS

We study the effects of strong lensing on the observed number counts of millimeter sources using a ray-tracing simulation and two number count models of unlensed sources. We employ a quantitative treatment of maximum attainable magnification factor depending on the physical size of the sources, also accounting for effects of lens halo ellipticity. We calculate predicted number counts and redshift distributions of millimeter galaxies including the effects of strong lensing and compare with the recent source count measurements of the South Pole Telescope (SPT). The predictions have large uncertainties, especially the details of the mass distribution in lens galaxies and the finite extent of sources, but the SPT observations are in good agreement with predictions. The sources detected by SPT are predicted to largely consist of strongly lensed galaxies at z > 2. The typical magnifications of these sources strongly depend on both the assumed unlensed source counts and the flux of the observed sources.
THE EVOLUTION OF ACCRETION IN YOUNG STELLAR OBJECTS: STRONG ACCRETORS AT 3–10 Myr

While the rate of accretion onto T Tauri stars is predicted to decline with age, objects with strong accretion have been detected at ages of up to 10 Myr. We analyze a sample of these old accretors, identified by having a significant U band excess and infrared emission from a circumstellar disk. Objects were selected from the ∼3 Myr σ Ori, 4–6 Myr Orion OB1b, and 7–10 Myr Orion OB1a star forming associations. We use high-resolution spectra from the Magellan Inamori Kyocera Echelle to estimate the veiling of absorption lines and calculate extinction for our T Tauri sample. We also use observations obtained with the Magellan Echellette and, in a few cases, the SWIFT Ultraviolet and Optical Telescope to estimate the excess produced in the accretion shock, which is then fit with accretion shock models to estimate the accretion rate. We find that even objects as old as 10 Myr may have high accretion rates, up to ∼10−8 M☉ yr−1. These objects cannot be explained by viscous evolution models, which would deplete the disk in shorter timescales unless the initial disk mass is very high, a situation that is unstable. We show that the infrared spectral energy distribution of one object, CVSO 206, does not reveal evidence of significant dust evolution, which would be expected during the 10 Myr lifetime. We compare this object to predictions from photoevaporation and planet formation models and suggest that neither of these processes have had a strong impact on the disk of CVSO 206.
Tidal interactions of a Maclaurin spheroid – II. Resonant excitation of modes by a close, misaligned orbit

We model a tidally forced star or giant planet as a Maclaurin spheroid, decomposing the motion into the normal modes found by Bryan (1889). We first describe the general prescription for this decomposition and the computation of the tidal power. Although this formalism is very general, forcing due to a companion on a misaligned, circular orbit is used to illustrate the theory. The tidal power is plotted for a variety of orbital radii, misalignment angles, and spheroid rotation rates. Our calculations are carried out including all modes of degree $l \le 4$, and the same degree of gravitational forcing. Remarkably, we find that for close orbits ($a/R_* \approx 3$) and rotational deformations that are typical of giant planets ($e\approx 0.4$) the $l=4$ component of the gravitational potential may significantly enhance the dissipation through resonance with surface gravity modes. There are also a large number of resonances with inertial modes, with the tidal power being locally enhanced by up to three orders of magnitude. For very close orbits ($a/R_* \approx 3$), the contribution to the power from the $l=4$ modes is roughly the same magnitude as that due to the $l = 3$ modes.
Factors associated with effects of COVID-19 vaccine among adults in Malaysia

Introduction: Globally, the needs for more focused research to understand the effects of COVID-19 vaccines among the population to verify the previous research and generate more reliable data. Therefore, this cross-sectional study was aimed to identify the factors associated with the effects of COVID-19 vaccination among adults in Malaysia. Methods: Malaysian people aged 18 and up were enrolled in a cross-sectional online survey. For data collection, a Google form was used to design an online questionnaire which was distributed through social media and in person by the author. Results: A total of 446 responses were analyzed. 58% participants received Pfizer BioNTech Covid 19 vaccine followed by Sinovac (21%) and AstraZeneca (16%). The most reported effect was local reaction pain, swelling and redness at the site of injection with 54.3% of participants. It was seen more in Pfizer BioNTech (56.8%) and AstraZeneca (57.1%) recipients in comparison to Sinovac recipients (42.9%), but this difference was not significant (x2=3.453; p-value=0.315). Tiredness/fatigue was the next most reported effect 51.3% by participants. The other more frequently reported effects were body pain (43.3%), muscle pain (41%), fever (41%) and headache (33%) respectively, which are significantly associated with the type of vaccine.
Learning mathematical rules with reasoning

This research focused on students learning of mathematical rules with reasoning. A small group of students (age 11-12 yrs) was observed closely by the first author as she taught them fraction rules. The area of focus was fractions and activities were designed pertaining to the four rules of fractions: addition, subtraction, multiplication, and division. The study was undertaken from a constructivist perspective of learning according to which students' learn through active participation in the construction of knowledge (Glasersfeld, 1995). This was significant in the context of mathematics classrooms in Pakistan which usually subscribe to the objectivist epistemology i.e. knowledge of the ultimate reality is possible. An implication of adhering to this epistemology is the knowledge transmission view of teaching and learning (Halai, 2000). Key findings of the study were that there were two significant factors that enabled students to learn rules with reasoning were: Teachers questions and opportunities for students to explain thinking; and opportunity for students to engage with concrete and semi concrete materials. The study also provides some useful insights into the sequence of teaching the fraction rules and raises implications for mathematics teaching and teacher education.
Shape of primordial non-Gaussianity and the CMB bispectrum

We present a set of formalisms for comparing, evolving, and constraining primordial non-Gaussian models through the CMB bispectrum. We describe improved methods for efficient computation of the full CMB bispectrum for any general (nonseparable) primordial bispectrum, incorporating a flat sky approximation and a new cubic interpolation. We review all the primordial non-Gaussian models in the present literature and calculate the CMB bispectrum up to $ll2000$ for each different model. This allows us to determine the observational independence of these models by calculating the cross correlation of their CMB bispectra. We are able to identify several distinct classes of primordial shapes---including equilateral, local, warm, flat, and feature (non-scale invariant)---which should be distinguishable given a significant detection of CMB non-Gaussianity. We demonstrate that a simple shape correlator provides a fast and reliable method for determining whether or not CMB shapes are well correlated. We use an eigenmode decomposition of the primordial shape to characterize and understand model independence. Finally, we advocate a standardized normalization method for ${f}_{\mathrm{NL}}$ based on the shape autocorrelator, so that observational limits and errors $\ensuremath{\Delta}{f}_{\mathrm{NL}}$ can be consistently compared for different models.
