Authors: Nigatu Balkachew , Abraham Tizita , Negash Geremew 
Published: August 2024

ABSTRACT
Uterine rupture is an obstetric emergency and which is associated with high maternal and fetal morbidity and mortality. It commonly occurs in uterus with one or more previous scar but is rare in unscarred uterus and especially without labor. The researcher presents a case of fundal uterine rapture in a 35 years old grand multipara who present with abdominal pain of 24 hours’ duration. But she has no history of pushing down pain (labor) and no history of trauma. Intraoperative finding showed fundal uterine rupture with a freshly dead baby free in the peritoneal cavity and total abdominal hysterectomy was done.

Authors: Dingeta Tariku , Olijira Lemessa , Alemayehu Tadesse , Akililu Ayalu 
Published: August 2024

Abstract
Back ground: First sexual intercourse is a milestone that varies considerably in its timing and its timing and represents an important developmental state. However, it has negative aspects such as unwanted pregnancy, sexually transmitted diseases and infection with HIV. Most adolescents do not use any form of contraception when entering into sexual intercourse for the first time.
Objective: To assess predictors of first sexual intercourse and associated risky sexual behaviors.
Methodology: This is an institution based cross-sectional study conducted from January to February 2010 among undergraduate students at Haramaya University. Quantitative data were collected from 846 randomly selected students.
Results: The majority (536,69.8%) of the students were male. From 843 participants 304(39.6%) ever had sex. The man (SD) age of first sex was 17.8(2.5) years. The majority of the respondents (138,45%) decided to have first sex because of falling in love, followed by curiosity (47,15.5%) of respondents. Out of the sexually active, 82(27%) had their first sexual intercourse with a casual partner. Less than half (42.8%) reported having used any contraceptive method during first sexual intercourse. Peer pressure, having friends who had sex, being male respondents, and discussion of sex related issues with boy or girl friend were among the factors predicting sexual initiation.
Conclusion: A sizable proportion of the participants had had initiated sexual intercourse. Peer pressure is the main reason mentioned for sexual initiation and risky sexual behaviors. Programs and intervention should seek to help individuals postpone their first sexual experience until they are ready for responsible decision making.

PREVALENCE OF INCISION EXTENSION DURING CESAREAN SECTION AT THREE TEACHING HOSPITALS IN ADDIS ABABA, ETHIOPIA
Authors: Abdella Ahmed , Tadesse Lia 
Published: August 2024

Abstract
Background: The most common major surgical procedure in obstetrics and gynecology in Cesarean Section (CS). Though advances in CS techniques, antibiotics, blood transfusion etc., have improved maternal and fetal outcomes. Cesarean delivery still poses higher maternal morbidity and mortality than vaginal delivery. One of the major causes of morbidity and mortality in CS is intra-operative hemorrhage which is partly caused by uterine incision extension (IE).
Objective: To determine the prevalence of uterine IE and assess factors associated with IE in CSs in three teaching hospitals in Addis Ababa, Ethiopia.
Methods: A cross-sectional study was undertaken from July 1 to August 30,2005 at three teaching hospital of Addis Ababa University. The data was entered and analyzed using EPI INFO statistical package, version 6.
Main Results: There were 42(12.7%) IEs among the 332 CS. Second state of labor (n=14, 34.1%), low station (m=16, 30.7%), occipito-posterior position (n=15, 25.4%), prolonged labor (21, 20.4%), rupture of membrane (n=16, 28.6%), and dystocia (n=86, 25.9%) were found to have significantly higher IE prevalence. Post-partum hemorrhage (PPH) due to tear of a vessel was seen in 33.3% of the IES. Even though the occurrence of IE was more common in those with emergency CS (13.4%), repeat CS (14.5%) and CS before term (16.7%) than elective (7.1%), primary (12.1%), and CS AT TERM (12.3%), respectively, the differences were not statistically significant.
Conclusion: IE is one major cause of intra-operative complications occurring in CS performed in the three teaching hospitals. In the presence of high risk factors (rupture of membranes, second stage of labor and low station of the presenting part), intra-operative complication should be anticipated and appropriate precautions made. Further studies are required to assess the long-term complications and better uterine incision techniques.

Plants and their derived compounds constitute a strong basis as potential drug and as novel therapeutic approach for the management of many diseases and illnesses. In this study we explored the chemical composition of the hydro-ethanolic extracts of M. vulgare and D. viscosa and their mixture. The antioxidant activity of these extracts was evaluated using the ABTS assay. Next, we examined the acute toxicity and sub-acute toxicity of the mixture. The molecular docking was conducted to discover the potential of compounds detected on NADPH oxidase. In the extract of D. viscosa the results revealed the presence of 4 compounds P-coumaric acid, caffeic acid, palmitic acid and stearic acid. In M. vulgare, only 3 compounds were identified: caffeic acid, stearic acid and palmitic acid which give the lowest ppm error (-5.67). The mixture of the two plants showed the presence of 2 fatty acids (palmitic acid and stearic acid), caffeic acid and daidzein. Concerning the antioxidant activity, the mixture (IC50=0.13±0.04 mg/mL) has the highest effect in the inhibition of ABTS followed by M. vulgare (IC50=0.143±0.03 mg/mL) and D. viscosa (IC50=0.162±0.05 mg/mL). The results of the acute toxicity showed that for 14 days and even a few hours after the administration of the mixture to the rats did not show any sign of toxicity, for the 2 doses administered (1000 and 2000 mg/kg). During 28 days of the test, no sign of toxicity was observed in the rats treated with the two doses (500 and 800 mg/kg). No significant difference was observed between the control group and the groups treated with the two doses in ALP, UREA, and CREA and a slight elevation of AST was observed in the group treated with the 500 mg/kg dose. Daidzein, myricetin, and vanillic acid were the molecules most active against NADPH oxidase with a glide gscore of -7.13, -6.597, and -6.12 kcal/mol,a glide emodel of -60.845, -67.752, and -45.821 kcal/mol, and a glide energy -40.807, -47.249, and -27.679 kcal/mol. In conclusion, both plants are effective as antioxidant agents and their mixture showed no sign of toxicity as herbal preparation.
Modic changes in patients with lumbar disc herniation followed more than 1 year after lumbar discectomy: a systematic review and meta-analysis
Authors: Feng Xiangyu , Nian Sunqi , Chen Jiayu , Li Na , Duan Pingguo 
Published: August 2024

Background
Modic changes (MCs) are identified as an independent risk factor for low back pain. Different subtypes of MCs vary in their impact on postoperative pain relief. However, consensus on the transformation of postoperative MC fractions in patients with distinct MC subtypes is lacking.

Methods
This comprehensive systematic review and meta-analysis searched English-language articles in PubMed, Cochrane Library, Web of Science, and Embase databases until January 2024. Studies included focused on patients transitioning between various microcrack subtypes post-discectomy. The primary outcome measure was the transformation between different postoperative microcrack fractions.

Results
Eight studies with 689 participants were analyzed. Overall, there is moderate to high-quality evidence indicating differences in the incidence of MC conversion across MC subtypes. The overall incidence of MC conversion was 27.7%, with rates of 37.0%, 20.5%, and 19.1% for MC0, MC1, and MC2 subtypes, respectively. Thus, postoperative MC type transformation, particularly from preoperative MC0 to MC1 (17.7%) or MC2 (13.1%), was more common, with MC1 transformation being predominant. Patients with preoperative comorbid MC1 types (19.0%) exhibited more postoperative transitions than those with MC2 types (12.4%).

Conclusion
This study underscores the significance of analyzing post-discectomy MCs in patients with lumbar disc herniation, revealing a higher incidence of MCs post-lumbar discectomy, particularly from preoperative absence of MC to MC1 or MC2. Preoperative MC0 types were more likely to undergo postoperative MC transformation than combined MC1 or MC2 types. These findings are crucial for enhancing surgical outcomes and postoperative care.

Authors: Li Xintong , He Weifeng , Wang Honghao , Xu Min 
Published: August 2024

Aims
This study evaluated millet germplasms in Liaoning Province to support the collection, preservation and innovation of millet germplasm resources.

Methods
The study was conducted from 2018 to 2020, involved the selection of 105 millet germplasm resources from the Germplasm Bank of the Liaoning Academy of Agricultural Sciences (LAAS), the observation and recording of 31 traits, and the application of multivariate analysis methods to assess phenotypic diversity.

Results
From the diversity analysis and correlation analysis, it was found that the tested traits had abundant diversity and complex correlations among them. Principal component analysis (PCA) comprehensively analyzed all quantitative traits and extracted seven principal components. Grey relational analysis (GRA) highlighted the varied contributions of different traits to yield. Through systematic cluster analysis (SCA), the resources were categorized into six groups at Euclidean distance of 17.09. K-mean cluster analysis determined the distribution interval and central value of each trait, then identified resources with desirable traits.

Conclusion
The results revealed resources that possess characteristics such as upthrow seedling leaves, more tillers and branches, larger and well-formed ears, and lodging resistance prefer to higher grain yield. It was also discovered that the subear internode length (SIL) could be an indicator for maturity selection. Four specific resources, namely, Dungu No. 1, Xiao-li-xiang, Basen Shengu, and Yuhuanggu No. 1, were identified for further breeding and practical applications.

Assessment and evolution of socio-environmental management of soybean farms participating in the Agro Plus program in Minas Gerais State, Brazil
Authors: Oliveira Antônio Consentino Teixeira , Silva Jr. Aziz Galvão da 
Published: August 2024

The Agro Plus program supports rural producers to comply with legislation and be prepared to meet demands of the international soybean market. This paper sought to analyze the current sustainability conditions of soybean farms in Minas Gerais based on the program checklist. The assessment of property improvements was carried out using data from 70 farms evaluated twice between 2016 and 2020 by the Agro Plus. The correlation between the soybean area cultivated in the season 2021 (ha) and the score for each of the 19 themes assessed by program (in %) was calculated and the t test was applied to verify the significance of the correlations. The program has a positive impact on soybean farms in Minas Gerais and contributes significantly to the management of properties in terms of compliance with current legislation. It enabled improvements in all the topics evaluated, with emphasis on those that were most critical before the farm joined Agro Plus. However, some themes are not suitable for most farms. Risk management at work, employee training, waste management and empty packaging storage and PPE laundry facilities have the lowest averages. Focusing on their indicators on second visits, distributing specific teaching materials and organizing courses on the subject seem interesting alternatives for Agro Plus to promote greater development on farms. There are significant correlations between the size of properties and socio-environmental issues, mainly related to labor issues and waste management on the property.

Zusammenfassung
Anlass des Beitrags war die Frage, ob private Schiedsgerichte tatsächlich ihrem Ruf genügen, eine kostengünstige, schnelle, kompetente und vertrauliche Alternative zur staatlichen Gerichtsbarkeit zu bieten. Der Aufsatz schildert die Antworten von 30 deutschen Wirtschaftskanzleien auf sechs Fragen in einem 2023 versandten Fragebogen. Im Ergebnis haben zwei Drittel der Befragten die hohe Attraktivität der Schiedsgerichte weitgehend bestätigt. Einzelne Stimmen monierten jedoch die hohen Verfahrenskosten, die mangelnde Unabhängigkeit der Richter/innen und die fehlende Überprüfung durch höhere Instanzen.
Climatology of long‐range transported Asian dust along the West Coast of the United States

Published: October 2014

AbstractThe contribution of trans‐Pacific dust estimated from satellite observations has been shown to be 3 times greater than domestic dust in North America throughout the year. Thus, a quantitative understanding of the frequency and locations where Asian dust is transported is necessary to improve global dust modeling for weather and climate predictions. This work presents a 10 year record (2002–2011) of dust along the U.S. West Coast estimated from the Interagency Monitoring of Protected Visual Environments network in an effort to characterize the seasonal cycle and interannual variability of Asian dust transport. In addition, observations of dust exported from East Asia were analyzed along with air mass trajectories and satellite and ground‐based precipitation data to investigate seasonal variability of Asian dust transport. On average, Asian dust concentrations (0.08–0.60 µg m−3) from ground‐based observations were 1.7 times those of local dust (0.00–0.53 µg m−3) and 23% (up to 44%) of fine particulate matter (particles with diameters ≤ 2.5 micrometers, or PM2.5) mass concentrations at high elevations in the spring. The maximum in springtime Asian dust on the U.S. West Coast was attributed to higher source concentrations (10.98–36.27 µg m−3) and reduced potential for wet removal over the Pacific Ocean and U.S. West Coast. Although trans‐Pacific transport was more favorable during the winter, minimum concentrations of Asian dust were observed on the U.S. West Coast (0.11 µg m−3) due to a lower source influence and higher potential for wet removal during transport. Multiobservational approaches such as these should be taken into account when modeling transport of Asian dust to the western U.S.
Lunar influence on equatorial atmospheric angular momentum
Authors: Bizouard Christian , Zotov Leonid , Sidorenkov Nikolay 
Published: October 2014

AbstractThis study investigates the relationship between the equatorial atmospheric angular momentum oscillation in the nonrotating frame and the quasi‐diurnal lunar tidal potential. Between 2 and 30 days, the corresponding equatorial component, called Celestial Atmospheric Angular Momentum (CEAM), is mostly constituted of prograde circular motions, especially of a harmonic at 13.66 days, a sidelobe at 13.63 days, and of a weekly broadband variation. A simple equilibrium tide model explains the 13.66 day pressure term as a result of the O1 lunar tide. The powerful episodic fluctuations between 5 and 8 days possibly reflect an atmospheric normal mode excited by the tidal waves Q1 (6.86 days) and σ1 (7.095 days). The lunar tidal influence on the spectral band from 2 to 30 days is confirmed by two specific features, not occurring for seasonal band dominated by the solar thermal effect. First, Northern and Southern Hemispheres contribute equally and synchronously to the CEAM wind term. Second, the pressure and wind terms are proportional, which follows from angular momentum budget considerations where the topographic and friction torques on the solid Earth are much smaller than the one resulting from the equatorial bulge. Such a configuration is expected for the case of tidally induced circulation, where the surface pressure variation is tesseral and cannot contribute to the topographic torque, and tidal winds blow only at high altitudes. The likely effects of the lunar‐driven atmospheric circulation on Earth's nutation are estimated and discussed in light of the present‐day capabilities of space geodetic techniques.

Published: October 2014

AbstractWe have analyzed 3 years of radio tracking data from the MESSENGER spacecraft in orbit around Mercury and determined the gravity field, planetary orientation, and ephemeris of the innermost planet. With improvements in spatial coverage, force modeling, and data weighting, we refined an earlier global gravity field both in quality and resolution, and we present here a spherical harmonic solution to degree and order 50. In this field, termed HgM005, uncertainties in low‐degree coefficients are reduced by an order of magnitude relative to earlier global fields, and we obtained a preliminary value of the tidal Love number k2 of 0.451 ± 0.014. We also estimated Mercury's pole position, and we obtained an obliquity value of 2.06 ± 0.16 arcmin, in good agreement with analysis of Earth‐based radar observations. From our updated rotation period (58.646146 ± 0.000011 days) and Mercury ephemeris, we verified experimentally the planet's 3:2 spin‐orbit resonance to greater accuracy than previously possible. We present a detailed analysis of the HgM005 covariance matrix, and we describe some near‐circular frozen orbits around Mercury that could be advantageous for future exploration.
Multiscale bed form interactions and their implications for the abruptness and stability of the downwind dune field margin at White Sands, New Mexico, USA
Authors: Pelletier Jon D. , Jerolmack Douglas J. 
Published: October 2014

AbstractThe downwind margin of White Sands dune field is an abrupt transition from mobile aeolian dunes to a dune‐free vegetated surface. This margin is also relatively stable; over the past 60 years it has migrated several times more slowly than the slowest dunes within the dune field, resulting in a zone of dune coalescence, aggradation, and, along most of the margin, development of a dune complex (i.e., dunes superimposed on draas). Repeat terrestrial laser scanning surveys conducted over a 3 month period demonstrate that sediment fluxes within the dune complex decrease on approach to the margin. Computational fluid dynamics modeling indicates that this decrease is due, in part, to a decrease in mean turbulent bed shear stress on the lee side of the dune complex as a result of flow line divergence or sheltering of the lee‐side dunes by the stoss side of the dune complex. Conservation of mass demands that this decrease in bed shear stress causes aggradation. We speculate that aggradation on the lee side of the dune complex further enhances the sheltering effect in a positive feedback, contributing to the growth and/or maintenance of the dune complex and a relatively abrupt and stable dune field margin. Our model and data add to a growing body of evidence that aeolian dune field patterns are influenced by feedbacks that occur at scales larger than individual dunes.

AbstractAllometry has been used to demonstrate a power–law scaling relationship in the brain of premature born infants. Forty‐nine preterm infants underwent neonatal MRI scans and neurodevelopmental testing at age 2 . Measures of cortical surface area and total cerebral volume demonstrated a power–law scaling relationship (α = 1.27). No associations were identified between these measures and investigated clinical variables. Term equivalent cortical surface area and total cerebral volume measures and scaling exponents were not related to outcome. These findings confirm a previously reported allometric scaling relationship in the preterm brain, and suggest that scaling is not a sensitive indicator of aberrant cortical maturation.
