Increased CO2 Levels during the First Half of Incubation at High Altitude Modifies Embryonic Development of Fertile Leghorn Breeder Eggs

The exchange of oxygen (O2) and carbon dioxide (CO2) within an incubator has a significant impact on embryonic development (ED) and hatching processes. This study examines the influence of non-ventilation (NV) conditions during the first ten days of incubation at high altitudes on Leghorn hens hatching eggs. Five hundred four hatching eggs were equally divided into three treatment groups and placed in twelve incubators (R = 4). The first group was subjected to standard ventilated conditions (V) during the setting phase. The ventilation inlet holes of the remaining incubators in the NV treatments were closed with either micropore (M) or polypropylene (P) tape, referred to as NVM and NVP groups, respectively. These two different airtight settings were intended to allow for a gradual rise in CO2 naturally generated by the embryos. Results indicate that carbon dioxide concentration gradually increased during the first half of incubation, reaching 1.42% in the NVM group and 1.20% in the NVP group, while the V condition group remained at 0.15%. From 10 days of incubation onwards, normal V conditions were restored in all incubators. The highest hatchability of fertile eggs (HFE) was shown by the NVP group (55.7%), followed by the V (52.6%) and NVM (38.6%) groups. The NVP group showed a greater yolk-free body mass (YFBM) from 10 days of incubation until the hatch basket transfer. NV conditions during the first 10 days of incubation at high altitude produced higher YFBM with gradually decreasing yolk sac mass. In comparison to the NVM and V conditions, the particular NVP condition showed a beneficial impact on the quality of hatched chicks. Sustaining NVP condition (1.2% of CO2) throughout the first half of incubation at high altitude generated the optimal environment in the incubator ensuring the best hatchability results. This study highlights how important it is for hatchery managers to recognize the influence of low O2 and high levels of CO2 on the development trajectories of Leghorn embryos during early incubation at high altitudes.

Age-specific differences in the association between prediabetes and cardiovascular diseases in China:A national cross-sectional study

BACKGROUND Cardiovascular disease(CVD)is a leading cause of morbidity and mortality worldwide,the global burden of which is rising.It is still unclear the extent to which prediabetes contributes to the risk of CVD in various age brackets among adults.To develop a focused screening plan and treatment for Chinese adults with prediabetes,it is crucial to identify variations in the connection between prediabetes and the risk of CVD based on age.AIM To examine the clinical features of prediabetes and identify risk factors for CVD in different age groups in China.METHODS The cross-sectional study involved a total of 46239 participants from June 2007 through May 2008.A thorough evaluation was conducted.Individuals with prediabetes were categorized into two groups based on age.Chinese atherosclerotic CVD risk prediction model was employed to evaluate the risk of developing CVD over 10 years.Random forest was established in both age groups.SHapley Additive exPlanation method prioritized the importance of features from the perspective of assessment contribution.RESULTS In total,6948 people were diagnosed with prediabetes in this study.In prediabetes,prevalences of CVD were 5(0.29%)in the younger group and 148(2.85%)in the older group.Overall,11.11%of the younger group and 29.59% of the older group were intermediate/high-risk of CVD for prediabetes without CVD based on the Prediction for ASCVD Risk in China equation in ten years.In the younger age group,the 10-year risk of CVD was found to be more closely linked to family history of CVD rather than lifestyle,whereas in the older age group,resident status was more closely linked.CONCLUSION The susceptibility to CVD is age-specific in newly diagnosed prediabetes.It is necessary to develop targeted approaches for the prevention and management of CVD in adults across various age brackets.

Prevalence of Enteric Pathogens Associated with Infections among Table Egg Consumers in Some Primary Health Establishments in the Center Region of Cameroon

Method: In Cameroon limited data are available regarding the prevalence of enteric bacteria associated with table egg consuming infections. As such, a situational-based study was performed in patients with complains of stomach disorders after egg consumption. Data related to sociodemographic characteristics and other factors were collected using a structured based questionnaire. Stool culture of utmost importance in stomach disorders patients and serum were collected for typhoid serological test. Results: A total of 207 participants took part in the survey, Results indicated nontyphoidal Salmonella infections were highest in the 3 areas of study with Mfoundi (73.44%) having the highest level of infection compared to other bacterial infection. other enteric bacteria associated to this infection were E. coli serotype 157, Aeromonas, Citrobacter freundii, Enterobacter cloaca and typhi salmonella. Meanwhile salmonelosis caused by typhic salmonella had highest prevalence in the Lekie Division (13.11%) as a result of poor hygienic practices associated with the conservation and preparation of eggs, Stool culture was observed to detect more positive cases in the diagnosis of typhoid fever than Widal test, but with no statistically significant (p > 0.05) difference between the stool culture and Widal test in the 3 areas of study. Conclusion: this study revealed that egg consumers are pruned to enteric bacterial and salmonella infections depending on how and where egg is consumed.

Afforestation with an age-sequence of Mongolian pine plantation promotes soil microbial residue accumulation in the Horqin Sandy Land, China

Land use change affects the balance of organic carbon(C)reserves and the global C cycle.Microbial residues are essential constituents of stable soil organic C(SOC).However,it remains unclear how microbial residue changes over time following afforestation.In this study,16-,23-,52-,and 62-year-old Mongolian pine stands and 16-year-old cropland were studied in the Horqin Sandy Land,China.We analyzed changes in SOC,amino sugar content,and microbial parameters to assess how microbial communities influence soil C transformation and preservation.The results showed that SOC storage increased with stand age in the early stage of afforestation but remained unchanged at about 1.27-1.29 kg/m2 after 52 a.Moreover,there were consistent increases in amino sugars and microbial residues with increasing stand age.As stand age increased from 16 to 62 a,soil pH decreased from 6.84 to 5.71,and the concentration of total amino sugars increased from 178.53 to 509.99 mg/kg.A significant negative correlation between soil pH and the concentration of specific and total amino sugars was observed,indicating that the effects of soil acidification promote amino sugar stabilization during afforestation.In contrast to the Mongolian pine plantation of the same age,the cropland accumulated more SOC and microbial residues because of fertilizer application.Across Mongolian pine plantation with different ages,there was no significant change in calculated contribution of bacterial or fungal residues to SOC,suggesting that fungi were consistently the dominant contributors to SOC with increasing time.Our results indicate that afforestation in the Horqin Sandy Land promotes efficient microbial growth and residue accumulation in SOC stocks and has a consistent positive impact on SOC persistence.

An Overview on the Composition and Age of Upper Crust of Proto-Tethyan Lajishan Intra-oceanic Arc,NE Tibet Plateau

Identification and anatomy of oceanic arcs within ancient orogenic belt are significant for better understanding the tectonic framework and closure process of paleo-ocean basin.This article summarizes the geological,geochemical,and geochronological characteristics of upper crust of Proto-Tethyan Lajishan intra-oceanic arc and provides new data to constrain the subduction evolution of the South Qilian Ocean.The intra-oceanic arc volcanic rocks,including intermediate-mafic lava,breccia,tuff,and minor felsic rocks,are distributed along southern part of the Lajishan ophiolite belt.Geochemical and isotopic compositions indicate that the intermediate-mafic lava were originated from depleted mantle contaminated by sediment melts or hydrous fluids,whereas the felsic rocks were likely generated by partial melting of juvenile mafic crust in intra-oceanic arc setting.Zircons from felsic rocks yield consistent and concordant ages ranging from 506 to 523 Ma,suggesting these volcanic rocks represent the relicts of upper crust of the Cambrian intra-oceanic arc.Combined with the Cambrian forearc ophiolite and accretionary complex,we suggest that the Cambrian intra-oceanic arc in the Lajishan ophiolite belt is belonging to the intra-oceanic arc system which was generated by south-directed subduction in the South Qilian Ocean at a relatively short interval between approximately 530 and 480 Ma.

Geographic patterns and climatic drivers of the mean genus age of liverworts in North America

Phylogenetic niche conservatism posits that species tend to retain ancestral ecological traits and distributions,which has been broadly tested for lineages originating in tropical climates but has been rarely tested for lineages that originated and diversified in temperate climates.Liverworts are thought to originate in temperate climates.Mean lineage age reflects evolutionary history of biological communities.Here,using regional liverwort floras across a long latitudinal gradient from tropical to arctic climates in North America,we test the age-component of the temperate niche conservatism hypothesis.Mean genus age(MGA)was estimated for each of 76 regional floras of liverworts.We related MGA to climatic variables for North America as a whole and for its eastern and western parts separately,and used variation partitioning analysis to assess the relative importance of temperature-versus precipitationrelated variables and of climate extremes versus seasonality on MGA.We found that older genera of liverworts tend to concentrate in humid regions of intermediate temperatures in the range of 10℃-20℃,from which liverworts have adapted to and diversified into more arid,colder,and hotter regions,supporting the temperate niche conservatism hypothesis.We also found that across North America the MGA of liverwort assemblages is more strongly affected by precipitation-related variables than by temperature-related variables,and is more strongly affected by climate extremes than by climate seasonality.Geographic patterns of the MGA of liverworts are consistent with the temperate niche conservatism hypothesis,rather than the tropical niche conservatism hypothesis,the latter of which is broadly supported by angiosperms.

The Exploration of Teaching Historical Narratives Through Edith Wharton’s The Age of Innocence

Wharton’s novels serve as compelling cases for understanding the complexities of late 19th-century American society.The paper uses The Age of Innocence as an example to examine detailed depiction of the era’s social hierarchy,fashion,architecture,and the intricate social rituals that defined New York’s upper class.It explores the constraints and dilemmas women faced within a patriarchal society,highlighting Wharton’s personal experiences and her critical stance on the social norms of her time.The characters of Newland Archer,May Welland,and Ellen Olenska are analyzed to reveal the pressures of societal expectations and the struggles for individual desires within a rigid social structure.Additionally,the paper proposes various teaching methods,including contextual understanding,literary analysis with a historical focus,and historical research projects,to enhance students’comprehension of the cultural and historical context of the novel.These methods aim to immerse students in the narrative and promote their understanding of the Gilded Age’s social dynamics.

Microbiomics and metabolomics insights into the microbial regulation on the formation of flavor components in the traditional fermentation process of Chinese Hongqu aged vinegar

This study aimed to investigate microbial succession and metabolic dynamics during the traditional fermentation of Hongqu aged vinegar,and explore the core functional microbes closely related to the formation of flavor components.Microbiome analysis demonstrated that Lactobacillus,Acetobacter,Bacillus,Enterobacter,Lactococcus,Leuconostoc and Weissella were the predominant bacterial genera,while Aspergillus piperis,Aspergillus oryzae,Monascus purpureus,Candida athensensis,C.xylopsoci,Penicillium ochrosalmoneum and Simplicillium aogashimaense were the predominant fungal species.Correlation analysis revealed that Acetobacter was positively correlated with the production of tetramethylpyrazine,acetoin and acetic acid,Lactococcus showed positive correlation with the production of 2-nonanone,2-heptanone,ethyl caprylate,ethyl caprate,1-hexanol,1-octanol and 1-octen-3-ol,C.xylopsoci and C.rugosa were positively associated with the production of diethyl malonate,2,3-butanediyl diacetate,acetoin,benzaldehyde and tetramethylpyrazine.Correspondingly,non-volatile metabolites were also detected through ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry.A variety of amino acids and functional dipeptides were identified during the traditional brewing of Hongqu aged vinegar.Correlation analysis revealed that Lactobacillus was significantly associated with DL-lactate,indolelactic acid,D-(+)-3-phenyllactic acid,pimelic acid,pregabalin and 3-aminobutanoic acid.This study is useful for understanding flavor formation mechanism and developing effective strategies for the suitable strains selection to improve the flavor quality of Hongqu aged vinegar.

Evaluation of the Integrated Management Program for Acute Malnutrition in the Douentza Health District, Mopti Region, Mali

Introduction: Malnutrition is a major public health problem in Mali, despite the efforts of the government, its technical and financial partners. The aim of this study was to evaluate the integrated management program for acute malnutrition (IMPAM). Methodology: This was a descriptive cross-sectional study that took place from January to December 2020 in the Douentza health district. The study included anyone with at least one malnourished child aged 6 to 59 months in their care who agreed to take part in the study, community health center staff who had given their consent, and the URENI manager at the Douentza reference health center. Data collected via questionnaires were entered into Excel and then analyzed using Epi-Info version 7 software. Results: A total of 138 acutely malnourished children aged 6 - 59 months, including 71 girls (51.45%), 138 accompanying mothers and 11 health workers, were included in our case study. Among the malnourished, 54.34% were in the 12 - 23 months age group and 69.57% had the severe form. 93% of the mothers interviewed were satisfied with the care provided, and all the health staff interviewed stated that community conflicts had an impact on IMPAM’s activities. Cure rates were 81% in Moderate Outpatient Nutritional Recovery and Education Unit (URENAM), 84% in Severe Ambulatory Nutritional Recovery and Education Unit (URENAS) and 92% in Recovery and Intensive Nutritional Education Unit (URENI). Drop-out rates were 19% in URENAM, 16% in URENAS and 0% in URENI. The death rate was 8% in URENI and 0% in URENAM and URENAS. Conclusion: This study confirms the high prevalence of malnutrition in the district (10.54%). It also reveals that factors such as inter-community conflict and insecurity have seriously affected the IMPAM program.

Contraception among Women Aged 35 and over at the University Hospital Center of Brazzaville

Objective: To study contraception among women aged 35 and over at the University Hospital of Brazzaville. Population and Methods: This was a retrospective descriptive study, conducted from April 1st 2017 to January 31st 2022 in the Obstetrics and Gynecology Department of the University Hospital of Brazzaville, including women aged 35 years and over who had received a contraceptive method. The study variables were sociodemographic, reproductive, clinical and contraceptive method related. Results: Two hundred and thirty customers were collected during the study period, i.e., 10.8% of the patients who received contraception. They were 38.4 ± 3 years old on average, had secondary education (46.1%), were of low socioeconomic status (54.3%), lived with a partner (98.7%) and came from an urban area (97.4%). They were multigravida (85.2%), and multiparous (63.9%) with an average of 4 living children. The indications were of two types: convenience (26.2%) and medical (73.8%). The most commonly used contraceptives were implants (72.2%) and injectable progestin (20.5%). Conclusion: The indication for contraception for women over 35 years of age at the University Hospital Center of Brazzaville is more medical, with the use of long-acting contraceptives.

Polymetamorphism of the ultrahigh-temperature granulites in the Rauer Group,East Antarctica:new evidence from zircon SHRIMP U-Pb ages

The Rauer Group is located on the eastern margin of the early Paleozoic Prydz Belt in East Antarctica,and the typical ultrahigh-temperature(UHT,>900℃)granulites outcrop on Mather Peninsula.However,the timing of UHT metamorphism and P–T path of the UHT granulites have long been debated,which is critical to understanding the tectonic nature and evolution history of the Prydz Belt.Thus,both a sapphirine-bearing UHT metapelitic granulite and a garnet-bearing UHT mafic granulite are selected for zircon SHRIMP U-Pb age dating.The results show that metamorphic zircon mantles yield weighted mean^(206)Pb/^(238)U ages of 918±29 Ma and 901±29 Ma for the metapelitic and mafic granulites,respectively,while zircon rims and newly grown zircons yield weighted mean^(206)Pb/^(238)U ages of 523±9 Ma and 532±11 Ma,respectively.These new zircon age data suggest that the UHT granulites may have experienced polymetamorphism,in which pre-peak prograde stage occurred in the early Neoproterozoic Grenvillian orogenesis(1000–900 Ma),whereas the UHT metamorphism occurred in the late Neoproterozoic to early Paleozoic Pan-African orogenesis(580–460 Ma).This implies that P–T path of the UHT granulites should consist of two separate high-grade metamorphic events including the Grenvillian and Pan-African events,which are supposed to be related to assembly of Rodinia and Gondwana supercontinents respectively,and hence the overprinting UHT metamorphic event may actually reflect an important intracontinental reworking.

Trace Element Status in Women of Childbearing Age in Kisangani, Democratic Republic of the Congo

Introduction: Trace element deficiency is a major nutritional problem worldwide, affecting more than two billion people, or around a quarter of the world’s population. This situation is even more acute in developing countries than in developed countries. In sub-Saharan Africa, research and recent data on trace elements (micronutrients) are scarce. The aim of this study was to determine the serum status of calcium (Ca+), copper (Cu), magnesium (Mg), selenium (Se) and zinc (Zn) in women of childbearing age in Kisangani. Methods: We have conducted a descriptive cross-sectional study in Kisangani, Democratic Republic of the Congo. Our sample consists of 596 women of childbearing age in apparent good health. The data collection has been prospective. Concentrations of trace elements in serum were analysed using an inductively coupled plasma mass spectrophotometer (ICP-MS Agilent 7700X). Results: The mean and median concentrations were: Calcium: 2.35 mmol/l and 2.31 mmol/l, Copper: 13.55 and 13.49 µmol/l, Magnesium: 0.85 and 0.81 mmol/l, Selenium: 0.99 and 0.76 µmol/l, and Zinc: 13.85 and 13.79 µmol/l. Respondents aged 20 - 34 had mean serum concentrations of 2.4 mmol/l for calcium, 13.7 µmol/l for copper, 0.9 mmol/l for magnesium, 1.1 µmol/l for selenium and 14.0 µmol/l for zinc. Conclusion: The trace element status of women of childbearing age in Kisangani was lower than that observed by other researchers, which suggests the need for a general nutritional intervention in our environment.

Adverse Pregnancy Outcomes Following Cryotherapy, Thermal Ablation, and Loop Electrosurgical Excision Procedure for Cervical Treatments among Reproductive Age Women in Zambia

Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Most recipients are women of reproductive age who, as reported in the literature, may be at risk of adverse pregnancy outcomes. This study investigated the risk of abortions, prematurity, stillbirths, and prolonged labor among reproductive-age women following Cryotherapy, Thermal ablation, and Loop Electrosurgical Excision Procedure treatments in Zambia. Methods: This cross-sectional study analyzed records of 8000 women aged 15 - 49 years at the Adult Infectious Disease Control Centre using records between January 2010 and December 2020. Women constituting the treatment group were all respondents treated by cryotherapy, thermal ablation, and LEEP, while the control group were VIA negative women. Women from both groups were invited to answer a phone survey. Data were analyzed using Stata version 16;descriptive analysis estimated the prevalence and obtained the frequency distribution of abortion, prematurity, prolonged labor and fresh stillbiths. Chi-square and Fisher’s exact test established the associations of CIN and APOs at 95% Confidence intervals. Univariate and multivariable binary logistic regression estimated the odds of adverse pregnancy outcomes across the three treatments. Results: Adverse pregnancy outcomes were more prevalent in the treatment group (39.2%) compared to the untreated group (16.9%). Across the two groups, normal outcomes were lower in the treated (42.3% vs 57.7%). The treated group accounted for the majority of abortions (74.5% vs 25.5%) and prolonged labor (72.5% vs 27.5%), while the untreated group accounted for higher proportions of stillbirths (66.7% vs 33.3%) and prematurity (53% vs 47%). Adverse pregnancy outcomes were five and two times more likely in women treated with thermal ablation (aOR = 5.05, 95% CI = 4.01 - 6.36, p Conclusion: Cervical treatment among Zambian women increases the risk of abortion and prolongs labor. Therefore, caution should be taken when administered to those of reproductive age. Vigilant monitoring should be maintained during pregnancy, delivery, and postpartum to improve maternal and neonatal health.

Introduction: Acute respiratory infections remain one of the main causes of mortality in children aged 0 to 5. This work aimed to study the associated factors with the occurrence of acute respiratory infections in children 0 to 5 years old in Yénawa, Cotonou in 2023. Subjects and Method: It was an analytical cross-sectional study of children aged 0 - 5 years and their mothers in Yénawa, selected by four-degree random sampling. The sampling size, calculated using the Schwartz formula, was 126 children and 126 mothers. The dependent variable was the occurrence of acute respiratory infections. The independent variables were classified into four groups: socio-demographic and economic characteristics, behavioral factors, child-related factors, and environmental factors. Data collected by observation and questionnaire survey were analyzed using STATA version 15 software. Associated factors were investigated by bivariate analysis and multiple logistic regression, at the 5% significance level. Results: A total of 126 children aged 0 - 5 years and 126 mothers were surveyed, aged 23.5 (11 - 36) months and 30 (18 - 48) years respectively. The prevalence of acute respiratory infections was 74.60% (CI95% = 66.89 to 82.30). The associated factors were the mother’s age between 18 and 28 (OR = 10.77;CI95% = 1.89 to 61.27;p = 0.007), the use of charcoal/wood for cooking (OR = 7.36;IC = 1.99 to 27.10;p = 0.003)), children's poor personal hygiene (OR = 8.87;IC = 2.92 to 26.97;p 0.001)), and cohabitation with domestic animals (OR = 7.27;IC = 1.67 to 31.71;p = 0.015). Conclusion: Communicating with mothers about the factors identified will help reduce the prevalence of acute respiratory infections in children aged 0 to 5.
