IntroductionHealth inequalities start early in life. The time of young adulthood, between late teens and early twenties, is especially interesting in this regard. This time of emerging adulthood, the transition from being a child to becoming an adult, is characterized by the detachment from parents and establishing of an own independent life. From a health inequality perspective, the question about the importance of the socio-economic background of parents is important. University students are an especially interesting group. Many students come from a privileged background and the question of health inequality among university students has not yet been properly studied.MethodsBased on the National Educational Panel Study (NEPS), we analyzed health inequalities among 9,000 students in Germany (∅ 20 years in the first year of their studies) over a period of 8 years.ResultsWe found that most university students (92%) in Germany reported a good and very good health. Yet, we still found substantial health inequalities. Students whose parents had a higher occupational status reported less health problems. Additionally, we observed that health inequalities had indirect impact on health via health behavior, psychosocial resources, and material conditions.DiscussionWe believe our study is an important contribution to the understudied subject of students' health. We see the impact of social inequality on health among such a privileged group like university students as an important sign of the importance of health inequality.
Online health information seeking and the association with anxiety among older adults
Authors: Schuster Amy M. , Ghaiumy Anaraky Reza , Cotten Shelia R. 
Published: February 2023

IntroductionThe Internet supplies users with endless access to a wealth of information and is generally the first source searched by U.S. adults (18 years and older) when seeking health information. Age and anxiety are associated with online health information seeking (OHIS). Older adults (65 years and older) are increasing their OHIS. Importantly, OHIS can potentially lead to improved health outcomes for older adults. The relationship between OHIS and anxiety is less clear. Studies report those with more symptoms of anxiety are more likely to be OHIS, while other studies find the reverse pattern or no association. Generalized anxiety disorder affects up to 11% of older adults and is oftentimes unrecognized and untreated.MethodsTo address the mixed findings in the literature, we analyzed six waves (2015–2020) of data from the National Health and Aging Trends Study to assess the causal relationship between anxiety and OHIS using a Random Intercept Cross-lagged Panel Model framework.ResultsWe found that while anxiety symptoms lead to OHIS in the next wave, OHIS was not associated with anxiety symptoms in the next wave.DiscussionThis suggests that for this sample of older adults, OHIS does not reduce or exacerbate older adults' symptoms of anxiety.

IntroductionPig seminal plasma (SP) is rich in active forms of all three isoforms (1-3) of transforming growth factor β (TGF-β), a chemokine modulatory of the immune environment in the female genital tract once semen is delivered during mating or artificial insemination (AI). The present study aimed to examine how TGF-βs are secreted by the epithelium of the male reproductive tract and how they are transported in semen, emphasizing the interplay with seminal extracellular vesicles (sEVs).MethodsSource of TGF-βs was examined by immunohistochemistry in testis, epididymis, and accessory sex glands, by immunocytochemistry in ejaculated spermatozoa, and by Luminex xMAP®technology in SP and sEVs retrieved from healthy, fertile male pigs used as breeders in AI programs.ResultsAll three TGF-β isoforms were expressed in all reproductive tissues explored and would be released into ductal lumen either in soluble form or associated with sEVs. Ejaculated spermatozoa expressed all three TGF-β isoforms, both inside and outside, probably the outer one associated with membrane-bound sEVs. The results confirmed that pig SP contains all three TGF-β isoforms and demonstrated that a substantial portion of them is associated with sEVs.DiscussionSeminal EVs would be involved in the cellular secretion of the active forms of seminal TGF-β isoforms and in their safe transport from the male to the female reproductive tract.

Published: February 2023

BackgroundGastric dilatation volvulus (GDV) can lead to organ failure including acute kidney injury (AKI). Due to its cytoprotective, antioxidant and anti-inflammatory effects, lidocaine has a potential to prevent AKI in dogs with GDV.Design and settingProspective, observational cohort study in client-owned dogs with GDV.ObjectiveTo determine concentrations of renal biomarkers for AKI in dogs with GDV with and without intravenous (IV) lidocaine therapy.MethodsThirty-two dogs were randomized to receive either IV lidocaine (2 mg/kg, followed by a lidocaine constant rate infusion at a dose of 50 μg/kg/min over 24 h; n = 17) or no lidocaine (n = 15). Blood and urine samples were taken at admission (T0) (only blood), during or immediately after surgery (T1), and 24 (T24) and 48 (T48) h after surgery. Plasma creatinine (pCr), plasma neutrophil gelatinase-associated lipocalin (pNGAL), urinary NGAL (uNGAL), uNGAL to creatinine ratio (UNCR), and urinary gamma-glutamyl transferase to creatinine ratio (uGGT/uCr) were evaluated. Biomarker concentrations were compared between dogs with and without IV lidocaine and the course of each marker was determined in comparison to its admission value.ResultsIn the entire population, a significantly higher pCr at T0 (median, 95 μmol/L, interquartile range, 82–105) compared with T1 (69 μmol/L, 60–78), T24 (63 μmol/L, 52–78), and T48 (78 μmol/L, 65–87) (P &lt; 0.001) was found. Plasma NGAL increased significantly between T0 (5.66 ng/mL, 3.58–7.43) and T24 (7.50 ng/mL, 4.01–11.89) (P = 0.006) and T48 (9.86 ng/mL, 5.52–13.92) (P &lt; 0.001), respectively. Urinary NGAL increased significantly between T1 (0.61 ng/mL, 0.30–2.59) and T24 (2.62 ng/mL, 1.86–10.92) (P = 0.001) and T48 (4.79 ng/mL, 1.96–34.97 (P &lt; 0.001), respectively. UNCR increased significantly between T1 (0.15 μg/mmol, 0.09–0.54) and T24 (1.14 μg/mmol, 0.41–3.58) (P = 0.0015) and T48 (1.34 μg/mmol, 0.30–7.42) (P &lt; 0.001), respectively. Concentrations of uGGT/uCr increased significantly from T0 highest at T24 (6.20 U/mmol, 3.90–9.90) and significantly decreased at T48 (3.76 U/mmol, 2.84–6.22) (P &lt; 0.001). No significant differences in any renal biomarker concentration were found between dogs with and without IV lidocaine therapy.Conclusion and clinical relevancePlasma NGAL, uNGAL and UNCR remained increased up to 48 h post-surgery. No evidence of lidocaine-associated renoprotection was found.

Stenotrophomonas maltophilia is a clinically relevant bacterial pathogen, particularly in cystic fibrosis (CF) patients. Despite the well-known ability to form biofilms inherently resistant to antibiotics and host immunity, many aspects involved in S. maltophilia biofilm formation are yet to be elucidated. In the present study, a proteomic approach was used to elucidate the differential protein expression patterns observed during the planktonic-to-biofilm transition of S. maltophilia Sm126, a strong biofilm producer causing chronic infection in a CF patient, to identify determinants potentially associated with S. maltophilia biofilm formation. In all, 57 proteins were differentially (3-fold; p < 0.01) expressed in biofilm cells compared with planktonic counterparts: 38 were overexpressed, and 19 were down-expressed. It is worth noting that 34 proteins were exclusively found in biofilm, mainly associated with quorum sensing-mediated intercellular communication, augmented glycolysis, amino acid metabolism, biosynthesis of secondary metabolites, phosphate signaling, response to nutrient starvation, and general stress. Further work is warranted to evaluate if these proteins can be suitable targets for developing anti-biofilm strategies effective against S. maltophilia.

Published: February 2023

Uncrewed aircraft systems (UASs) are a popular tool when surveilling for invasive alien plants due to their high spatial and temporal resolution. This study investigated the efficacy of a UAS equipped with a three-band (i.e., red, green, blue; RGB) sensor to identify invasive Phragmites australis in multiple Minnesota wetlands using object-based image analysis (OBIA) and machine learning (ML) algorithms: artificial neural network (ANN), random forest (RF), and support vector machine (SVM). The addition of a post-ML classification OBIA workflow was tested to determine if ML classifications can be improved using OBIA techniques. Results from each ML algorithm were compared across study sites both with and without the post-ML OBIA workflow. ANN was identified as the best classifier when not incorporating a post-ML OBIA workflow with a classification accuracy of 88%. Each of the three ML algorithms achieved a classification accuracy of 91% when incorporating the post-ML OBIA workflow. Results from this study suggest that a post-ML OBIA workflow can increase the ability of ML algorithms to accurately identify invasive Phragmites australis and should be used when possible. Additionally, the decision of which ML algorithm to use for Phragmites mapping becomes less critical with the addition of a post-ML OBIA workflow.

Abstract
We report on the demonstration of GaN:Eu/GaN nanowire (NW) LEDs grown by organometallic vapor phase epitaxy (OMVPE). The GaN:Eu/GaN NW LED structures with a large aspect ratio (>8) are formed by selective-area OMVPE, and have pedestals that are free from lateral overgrowth of p-GaN in order to prevent short circuiting. The structures are embedded in polydimethylsiloxane followed by a wet-etching process to expose the tips of NW LEDs for contacting. Red luminescence with a narrow linewidth originating from Eu3+ ions is observed at room temperature under current injection in the GaN:Eu/GaN NW LEDs.

Abstract
Motion compensation was applied in the envelope statistical analysis to develop robust thermometry for in vivo situations. Numerical data were reproduced with the temporal change in the scatterer distribution due to thermal expansion and arbitrary translational motions, and experimental phantom data were obtained under heating with the probe motion. Additionally, the case under respiratory motion was evaluated using the data collected from in vivo rat tumor. Ultrasound signals were acquired using a 7.5 MHz linear probe, and their misalignments of envelopes due to the motions were compensated by a block-matching-based motion estimator. The absolute change in the Nakagami shape parameter,

in each frame was calculated by normalizing with the initial frame to indicate the temperature change. The uncompensated

<p>Perdebatan bahwa seorang perempuan tidak bisa menjadi pemimpin suatu negara atau pemerintahan masih menjadi polemik sampai saat ini. Dalam pandangan Islam, seorang laki-laki mempunyai tanggung jawab yang besar dalam memimpin keluarga, dan masyarakat serta negara. Hal ini karena di dalam Al-qur’an salah satunya surat An-nisa ayat 34, Al-baqarah ayat 228, surah Yusuf ayat 109, At-thamrin ayat 10, menyatakan bahwa seorang laki-laki memimpin kaum perempuan, yang dimaknai oleh para ulama bahwa yang bisa menjadi seorang pemimpin hanyalah seorang laki-laki karena laki-laki diberi Allah kelebihan fisik yang lebih kuat dibandingkan perempuan, laki-laki yang pergi ke medan perang dan dikuatkan oleh hadist yang menyatakan bahwa suatu kaum tidak akan bahagia apabila mereka menyerahkan kepemimpinan kepada seorang perempuan. Tetapi tidak dapat dipungkiri juga, bahwa fakta sejarah Islam menyatakan bahwa banyak pemimpin Islam di zaman Nabi seperti Ratu Bilqis, Asiyah binti Muzahim, Siti khodijah yang merupakan perempuan yang mempunyai peran di masyarakat arab. Berdasarkan hal tersebut, artikel ini mengulas masalah apakah seorang perempuan boleh menjadi pemimpin berdasarkan perspektif Islam dan apa saja batasan-batasannya.</p>

Dalam memutuskan untuk membeli mobil biasanya beberapa faktor dijadikan pertimbangan untuk menentukan keputusan akhir. Maka dari itu sejumlah faktor pendukung seperti harga, type, merk, dan lain sebagainya penting untuk diperhatikan. Pada penelitian ini optimasi model algoritma multilayer perceptron digunakan untuk memodelkan prediksi daya beli mobil konsumen dari dataset publik yang bersumber dari kaggle untuk menemukan model paling optimal terhadap keputusan membeli mobil. Multilayer perceptron sering diterapkan untuk meneliti data yang kompleks karena mampu mengnalisa data dengan baik. Prediksi niat beli tidak hanya dapat mengurangi biaya dealer mobil, tetapi juga mempengaruhi strategi pemasaran dealer mobil dalam jangka panjang. Pengujian menggunakan model Multilayer Perceptron (MLP) dengan konfigurasi default dan hypertuning parameter dilakukan dengan membandingkan dua parameter optimasi yang berbeda yaitu parameter Adam dan RMSprop. Hasilnya didapatkan evaluasi optimal dari konfigurasi default pada parameter optimasi Adam dengan maksimum learning rate 0.01 dengan akurasi 89.50% dan 87,50% untuk optimasi RMSprop sedangkan pengujian dengan konfigurasi hyperparameter tuning dengan dua parameter optimasi yang sama Adam dan RMSprop dengan nilai maksimum learning rate 0,001 didapatkan akurasi sebesar 92.00% untuk parameter RMSprop dan 91,5% pada parameter Adam.

Published: February 2023

Fresh fruits promote good health but harbor a wide range of microbial contaminants. This study assessed the microbial quality of fruits and safety of Polyethylene packed sliced fruits sold in Port-Harcourt markets. 36 samples of freshly cut fruit comprising of Pawpaw (Carica papaya), Pineapple (Ananas comosus) and Water Melon (Citrullus lanatus) were randomly collected from different sellers within Port Harcourt metropolis. Samples were analyzed using standard microbiological methods. Mean Total viable count ranged from Log10cfu/g5.85 – 6.34, mean Total Fungi Count Log10cfu/g 3.23– 3.85. Nine bacteria were identified. Staphylococcus aureus (27.4%) was the most frequently isolated followed by Shigella spp (19.4%), Escherichia coli (16.1%), Bacillus spp(14.5%), Aeromonas Sp(8%), Enterobacter sp(4%), Klebsiella spp and Salmonella spp (4.8%) respectively. Samples of Pawpaw had high microbial contamination when compared to other fruit samples. The study comes to the conclusion that consumers' awareness of the risks of eating packed sliced fruits should be increased, and that they should once again insist on properly processed/packaged sliced fruits.
