Prevalence of Polycystic Ovary Syndrome Awareness Among Female Medical Students

Background: Polycystic ovary syndrome is one of the most common causes of infertility in woman, affecting 4-18% of reproductive aged women worldwide. It is characterized by hormonal imbalance leading to reproductive, metabolic and psychological dysfunction. It is a multi-organ syndrome affecting both female gonads and the pituitary gland. Polycystic ovary syndrome is idiopathic in occurrence. However, recent studies suggest that it can be caused by inherent abnormalities of ovarian steroidogenesis, follicular development, excessive gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH), and reduced follicle stimulating hormone (FSH) secretion. Objectives: To evaluate the knowledge and level of awareness of female students about polycystic ovary syndrome. To determine the prevalence of the symptoms of polycystic ovary syndrome. Methods: A cross sectional type of quantitative study was conducted following the approval from the Ethical Review Committee. The study was carried out on a sample of medical students, with a calculated sample size of 278 individuals according to the World Health Organization (WHO) formula. A questionnaire-based survey was implemented. Results: The most important question was regarding the awareness of polycystic ovary syndrome and to our interest 74.5% of the participants were aware of the disease. 42.2% of the participants gained knowledge of the disease from social media and the internet. The diagnosed cases of polycystic ovary syndrome in the sample was 11.2%, among which 41.9 % are receiving the treatment. Conclusion: The majority of the female medical students (74.5%) were aware of polycystic ovary syndrome in female medical students. 33.8% of the participants had a normal menstrual cycle of 28 days. A noticeable percentage of students had polycystic ovary syndrome and were under treatment. Our study can be further used to determine relations between polycystic ovary syndrome and a variety of factors, such as the duration of menstrual cycle, body mass index (BMI) or symptoms of this syndrome, such as the weight gain and acne.
A New rGO‐Overcoated Sb2Se3 Nanorods Anode for Na+ Battery: In Situ X‐Ray Diffraction Study on a Live Sodiation/Desodiation Process

Sodium ion batteries (SIBs) are a promising alternative to lithium ion batteries for a broader range of energy storage applications in the future. However, the development of high‐performance anode materials is a bottleneck of SIBs advancement. In this work, Sb2Se3 nanorods uniformly wrapped by reduced graphene oxide (rGO) as a promising anode material for SIBs are reported. The results show that such Sb2Se3/rGO hybrid anode yields a high reversible mass‐specific energy capacity of 682, 448, and 386 mAh g−1 at a rate of 0.1, 1.0, and 2.0 A g−1, respectively, and sustains at least 500 stable cycles at a rate of 1.0 A g−1 with an average mass‐specific energy capacity of 417 mAh g−1 and capacity retention of 90.2%. In situ X‐ray diffraction study on a live SIB cell reveals that the observed high performance is a result of the combined Na+ intercalation, conversion reaction between Na+ and Se, and alloying reaction between Na+ and Sb. The presence of rGO also plays a key role in achieving high rate capacity and cycle stability by providing good electrical conductivity, tolerant accommodation to volume change, and strong electron interactions to the base Sb2Se3 anode.
Automated segmentation of microtomography imaging of Egyptian mummies

Propagation Phase Contrast Synchrotron Microtomography (PPC-SRμCT) is the gold standard for non-invasive and non-destructive access to internal structures of archaeological remains. In this analysis, the virtual specimen needs to be segmented to separate different parts or materials, a process that normally requires considerable human effort. In the Automated SEgmentation of Microtomography Imaging (ASEMI) project, we developed a tool to automatically segment these volumetric images, using manually segmented samples to tune and train a machine learning model. For a set of four specimens of ancient Egyptian animal mummies we achieve an overall accuracy of 94–98% when compared with manually segmented slices, approaching the results of off-the-shelf commercial software using deep learning (97–99%) at much lower complexity. A qualitative analysis of the segmented output shows that our results are close in terms of usability to those from deep learning, justifying the use of these techniques.
Impact of Educational Intervention on Preventive Strategies for Cardiovascular Disease Risk Modification among Patients with Type II Diabetes Mellitus

Objective: The Type II Diabetes mellitus (DM) patients were stratified into CVD risk categories. The lifestyle and prescription pattern of DM patients was studied. Also, impact of educational intervention on preventive strategies for CVD risk modification was assessed. Methods: The WHO Cardiovascular disease (CVD) risk prediction charts were used to categorize DM into various CVD risk categories and were imparted education intervention based on WHO Guidelines for Assessment and Management of CVD Risk. Results: 67.5 % of DM had low, 15 % medium, 15 % high and 2.5 % had very high CVD risk. 100 % of DM patients with high CVD risk profile were on antihypertensive and antiplatelet drugs though only 50 % were on hypolipidemic agents. Educational intervention improved the knowledge regarding preventive strategies for CVD Risk modification {weight control (p<0.05), glycemic control (P<0.01), benefits of hypolipidemic agents (p<0.01) and antiplatelet drug aspirin (P<0.001) usage}. Conclusion: 32.5 % Type 2 diabetic patients have medium to very high risk of developing a cardiovascular event. There is a scope to increase the prescription of hypolipidemic drugs for CVD risk modification. Educational intervention resulted in a significant increase in knowledge regarding preventive strategies for CVD Risk modification.
Analysis of the floristic diversity in a southern Mediterranean ecosystem. Case of Bissa forest, Chlef (Algeria)

The forest of Bissa is a Mediterranean ecosystem, characterized by a high floristic diversity. In order to assess the floristic diversity in this forest, 133 floristic readings were conducted in this area between 2013 and 2017. As a result, it was possible to identify 151 species, 125 genus and 54 botanical families, with a clear dominance of Asteraceae, Fabaceae and Poaceae. Biologically, this ecosystem was mainly dominated by therophytes (37%). Physiognomically, the phanerophytes were the most dominant types, whereas in term of phytogeography this forest was dominated by the Mediterranean type (50%). According to Shannon-Winner index, this area was characterized by a relatively low diversity (1.3 bit / ind), with a clear dominance of a few species. Finally this forest was relatively disturbed (42%) and under a strong anthropozoic influence.
Detection of Negative Pickup Ions at Saturn's Moon Dione

We investigate a possible negative ion feature observed by the Cassini Plasma Spectrometer (CAPS) during a flyby of Saturn's moon Dione that occurred on 7 April 2010. By examining possible particle trajectories, we find that the observed particles are consistent with negative pickup ions originating near the moon's surface. We find that the mass of the negative pickup ions is in the range of 15–25 u and tentatively identify this species as O−, likely resulting from ionization and subsequent pickup from Dione's O2‐CO2 exosphere. Our estimates show that the negative ion density is ~3 × 10−3 cm−3. This is comparable to, but slightly smaller than, that previously reported for the density of O2+ pickup ions for the same flyby, indicating that negative pickup ions may represent a major loss channel for Dione's exosphere.
Expanding the knowledge of Helicobacter pylori – new directions, new challenges

Introduction Helicobacter pylori (H. pylori) infection is prevalent worldwide. As it is a known carcinogen, causing multitude of gastrointestinal end extra-gastric disorders, the eradication therapy is now indicated for every patient diagnosed with this infection. This approach may prove however to be improper, since it is now known, that not every strain of this species is pathogenic, therapy may be unsuccessful and drug resistance is ever increasing problem. A brief description of the state of knowledge: H. pylori is a species representing multiple strains with distinct regional genetic markup. Its prevalence is high in the general population, but in the recent years there have been reports of decreased presence in the developed countries. This paper reviews most important known genetic diversity markers and their impact on virulence and toxicity of species. It also covers possible new ways to combat the infection. Conclusion With increased possibility of genetic sequencing, there may be possibility for custom-tailored eradication therapy of H. pylori in the future.
Resource Modification On Multicore Server With Kernel Bypass

Technology develops very fast marked by many innovations both from hardware and software. Multicore servers with a growing number of cores require efficient software . Kernel and Hardware used to handle various operational needs have some limitations. This limitation is due to the high level of complexity especially in handling as a server such as single socket discriptor, single IRQ and lack of pooling so that it requires some modifications. The Kernel Bypass is one of the methods to overcome the deficiencies of the kernel. Modifications on this server are a combination increase throughput and decrease server latency. Modifications at the driver level with hashing rx signal and multiple receives modification with multiple ip receivers, multiple thread receivers and multiple port listener used to increase throughput. Modifications using pooling principles at either the kernel level or the program level are used to decrease the latency. This combination of modifications makes the server more reliable with an average throughput increase of 250.44% and a decrease in latency 65.83%.
Revizor: Fuzzing for Leaks in Black-box CPUs

Shared microarchitectural state has become a prime target for side-channel attacks that leverage timing measurements to leak information across security domains. Combined with speculative execution, they cause vulnerabilities like Spectre and Meltdown. Such vulnerabilities often stay undetected for a long time because we lack the tools for systematic testing of CPUs against them. In this paper, we propose an approach to automatically detect microarchitectural information leakage in commercial black-box CPUs. We base our approach on speculation contracts, which we employ to specify the permitted side effects of program execution on the microarchitectural state. We propose a technique, called Model-based Relational Fuzzing (MRF), that enables testing of CPUs against these specifications. We implement MRF in a fuzzing framework called Revizor, and showcase its effectiveness on real Intel x86 CPUs: It automatically detects violations of a rich set of contracts, or indicates their absence. A highlight of our findings is that Revizor managed to automatically surface Spectre, MDS, and LVI by fuzzing against increasingly liberal contracts.

Effect of Precursor Solution Aging on the Crystallinity and Photovoltaic Performance of Perovskite Solar Cells

Perovskite materials due to their exceptional photophysical properties are beginning to dominate the field of thin‐film optoelectronic devices. However, one of the primary challenges is the processing‐dependent variability in the properties, thus making it imperative to understand the origin of such variations. Here, it is discovered that the precursor solution aging time before it is cast into a thin film, is a subtle but a very important factor that dramatically affects the overall thin‐film formation and crystallinity and therein factors such as grain growth, phase purity, surface uniformity, trap state density, and overall solar cell performance. It is shown that progressive aging of the precursor promotes efficient formation of larger seeds after the fast nucleation of a large density of small seeds. The hot‐casting method then leads to the growth of large grains in uniform thin‐films with excellent crystallinity validated using scanning microscopy images and X‐ray diffraction patterns. The high‐quality films cast from aged solution is ideal for thin‐film photovoltaic device fabrication with reduced shunt current and good charge transport. This observation is a significant step toward achieving highly crystalline thin‐films with reliability in device performance and establishes the subtle but dramatic effect of solution aging before fabricating perovskite thin‐films.

Hierarchically structured polymeric ionic liquids and polyvinylpyrrolidone mat-fibers fabricated by electrospinning

Different polymeric ionic liquids/polyvinylpyrrolidone (PILs/PVP) fiber membranes were prepared by electrospinning from the corresponding polymeric blends. Supramolecular interpolymeric interactions between PILs and PVP seem to define not only the solution properties but also the final morphology and performance of the mat-fibers. The fine tuning of the counter anion and the length of the alkyl chain allows modulating both their hydrophilic/hydrophobic properties and their morphology. In this way, it was possible to obtain materials with potential applications in different fields as highlighted by the promising results obtained for oil–water separation or for the synthesis and stabilization of AuNPs.
WEAK EQUILIBRIUMS FOR TIME-INCONSISTENT STOPPING CONTROL PROBLEMS

This paper studies time-inconsistent stopping control problems under general multidimensional controlled diffusion model. We first formulate the time-inconsistent stopping control problems and propose a formal definition of their equilibriums. This definition for equilibriums is consistent with the ones in pure control/stopping problems and thus can be seen as nontrivial extension to the existing theory. We show that an admissible pair (û, C) of control-stopping policy is equilibrium if and only if the axillary function associated to it solves the extended Hamiltonian system. We provide almost equivalent conditions to the boundary term of this Hamiltonian system, which is basically the celebrated smooth fitting principles. In this paper we further reformulate them and propose strong and weak smooth fitting principles. We also give one concrete example that illustrates our theoretical results.
Biometrics: Trust, But Verify

Over the past two decades, biometric recognition has exploded into a plethora of different applications around the globe. This proliferation can be attributed to the high levels of authentication accuracy and user convenience that biometric recognition systems afford end-users. However, in-spite of the success of biometric recognition systems, there are a number of outstanding problems and concerns pertaining to the various sub-modules of biometric recognition systems that create an element of mistrust in their use - both by the scientific community and also the public at large. Some of these problems include: i) questions related to system recognition performance, ii) security (spoof attacks, adversarial attacks, template reconstruction attacks and demographic information leakage), iii) uncertainty over the bias and fairness of the systems to all users, iv) explainability of the seemingly black-box decisions made by most recognition systems, and v) concerns over data centralization and user privacy. In this paper, we provide an overview of each of the aforementioned open-ended challenges. We survey work that has been conducted to address each of these concerns and highlight the issues requiring further attention. Finally, we provide insights into how the biometric community can address core biometric recognition systems design issues to better instill trust, fairness, and security for all.
STUDI IN SILICO SINGLE CHAIN VARIABLE FRAGMENT (SCFV) SELEKTIF TERHADAP HORMON BASIC NATRIURETIC PEPTIDE (BNP)

Basic natriuretic peptide (BNP) merupakan polipeptida yang terdiri dari 32 asam amino yang disekresikan oleh bilik jantung untuk merespon peregangan yang berlebihan pada sel otot jantung. Pengeluaran BNP dimodulasi oleh ion kalsium. BNP berpotensi untuk digunakan sebagai marker untuk meramalkan pasien yang mengalami gagal jantung. Anti BNP single chain variable fragment (Anti BNP SCFV) merupakan gabungan polipeptida antara daerah yang bervariasi pada rantai heavy (VH) dan rantai light (VL) dari immunoglobulin. Anti BNP SCFV akan berikatan dengan BNP melalui pengenalan antigen-antibodi yang biasanya berada pada daerah CDR ( Complementary Determining Region ) yang merupakan bagian dari SCFV. Tujuan penelitian ini adalah untuk mempelajari selektivitas docking SCFV yang diperoleh dari Protein Data Bank (PDB) dengan BNP berdasarkan parameter energi intermolekular secara in silico . SCFV terpilih dimodifikasi melalui penggantian asam amino yang berperan pada interaksi untuk mendapatkan SCFV yang lebih selektif terhadap BNP dengan energi interaksi intermolekular yang lebih rendah. Docking dilakukan menggunakan program Autodock 4.2. 3. Visualisasi dilakukan menggunakan program Molegro Virtual Viewer. Hasil penelitian menunjukkan SCFV dengan ID-PDB 4OUO merupakan SCFV yang selektif terhadap BNP dengan energi intermolekular -12,81 kkal/mol, Ki 0,9712 M, namun energi ikatan yang positif: 17,33 kkal/mol. Penggantian asam amino arginin 116 menjadi histidin pada SCFV 4OUO memperlihatkan pengikatan yang lebih selektif terhadap BNP dengan energi intermolekul -13,66 kkal/mol, energi ikatan 16,47 kkal/mol, dan Ki 0,9726 M. Bagaimanapun, metode prediksi interaksi antara BNP dan SCFV perlu dikembangkan lebih lanjut untuk mendapatkan hasil yang lebih baik.
Test of lepton flavour universality in $b\to s\ell^+\ell^-$ decays

The Standard Model of particle physics predicts that charged leptons have the same electroweak interaction strength. This symmetry, called lepton flavour universality, was found to hold in a wide range of particle decays. One observable that is sensitive to lepton flavour universality is the ratio of branching fractions $R_K=\mathcal B(B^+\to K^+\mu^+\mu^-)$ $/$ $\mathcal B(B^+\to K^+e^+e^-)$. This quantity is measured using $9$ fb$^{-1}$ of proton-proton collision data recorded by the LHCb experiment at CERN's Large Hadron Collider. For the dilepton invariant mass squared range $q^2\in(1.1$ $\text{Ge}\kern -0.1em \text V^2,$ $6.0$ $\text{Ge}\kern -0.1em \text V^2)$, the result is $R_K=0.846^{+0.042}_{-0.039}{}^{+0.013}_{-0.012}$, where the first uncertainty is statistical and the second systematic. The measured value is in tension with the Standard Model prediction at the level of $3.1$ $\sigma$, thus providing evidence for the violation of lepton flavour universality in $B^+\to K^+\ell^+\ell^-$ decays.
Modification of Ca2+-crosslinked Sodium Alginate/Gelatin Films with Propolis for an Improved Antimicrobial Action

Problems associated with microbial resistance to antibiotics are growing due to their overuse. In this scenario, plant extracts such as the propolis extract (PE) have been considered as potential alternatives to antibiotics in the treatment of infected wounds, due to its antimicrobial properties and ability to induce tissue regeneration. To improve the long-term effectiveness of PE in wound healing, polymeric films composed of biodegradable and biocompatible polymers are being engineered as delivery vehicles. Here, sodium alginate/gelatin (SA/GN) films containing PE were prepared via a simple, green process of solvent casting/phase inversion technique, followed by crosslinking with calcium chloride (CaCl2) solutions. The minimum inhibitory concentration (MIC) of PE was established as 0.338 mg/mL for Staphylococcus aureus and 1.353 mg/mL for Pseudomonas aeruginosa, the most prevalent bacteria in infected wounds. The PE was incorporated within the polymeric films before (blended with the polymeric solution) and after (immobilization via physisorption) their production. Flexible, highly hydrated SA/GN/PE films were obtained, and their antibacterial activity was assessed via agar diffusion and killing time kinetics examinations. Data confirmed the modified films effectiveness to fight bacterial infections caused by S. aureus and P. aeruginosa and their ability to be applied in the treatment of infected wounds.
