Собственная история и внутренний мир Орды в новой книге Мари Фаверо
Authors: Ускенбай Канат З.
Published: May 2024

The article is devoted to a review of the new book by Dr. Marie Favereau, professor of history at the University of Paris - Nanterre, “The Horde: How the Mongols Changed the World.” (Marie Favereau. The Horde: How the Mongols Changed the World. Harvard University Press, 2021). The book makes an attempt to present the history of the Horde from the inside, from its own positions. Marie Favero managed to show her own history and the inner world of the Horde, its role and place in world history. For the Kazakh reader, it is important that the history of the Horde ulus, which was located on most of the modern territory of Kazakhstan, received bright, scientific and reliable coverage in the book. Today Kazakhstan positions itself as the heir of the Horde, and in this regard, the author of the book’s opinion is important that the history of the Horde is a common heritage and it cannot belong exclusively to the national narratives of any nation states. The objective history of the Horde depends on the position of historians, and our task is to jointly resist nationalism in science. The first and important element of such a fight is the promotion and popularization of scientific research, one of which is the book under review. In this regard, it is vitally necessary to translate the book not only into other European languages, but also into the languages of the numerous heirs of the Golden Horde, primarily the Kazakh language

Discrimination Experienced by Women Living with HIV and AIDS Accessing Reproductive Health Services
Authors: Tamang Bhim
Published: May 2024

Women with disclosed HIV status experience different barriers and are stigmatized and discriminated against in health services. The sexual and reproductive health of women living with HIV is critical when compared to those who are not living with HIV. Discriminatory behaviour in health settings decreases the morale of women and limits the care of their health. Women living with HIV hide their status because of fear of discrimination, which puts the health personnel at high risk of transmission. The goal of this study was to learn more about the reasons for and types of discrimination faced by HIV-positive women seeking reproductive health services in healthcare settings. The researcher found three significant findings. To begin with, pre-existing social attitudes, perceptions, and information regarding women with HIV are at the foundation of stigma and discrimination in healthcare settings. Second, the forms of stigma and prejudice that WLHIV perceived or experienced differed from each other, regardless of which service under reproductive health they sought. Finally, due to such discrimination, WLHIV refuses to disclose their HIV status, delaying or avoiding seeking medical help, experiencing emotional stress, and having low self-esteem.

Unveiling the Nexus: Most Essential Learning Competencies and Critical Thinking Skills of Students
Authors: Catanus Everon Joy
Published: May 2024

Knowledge and critical thinking (CT) play vital roles and serve as foundational pillars for effective learning and intellectual development. This study aimed to identify the relationship between students’ knowledge of the Most Essential Learning Competencies (MELCs) in English 7 and their CT skills. The descriptive-correlational approach was used, and survey questionnaires were utilized as the main data collection tool. Using the systematic sampling technique, 145 students from two secondary schools in Zamboanguita District 2 were selected as the respondents for this study. The results showed that the students’ level of knowledge of the MELCs is predominantly categorized as “outstanding.” The data also reflects that the students generally perceive a “somewhat high” extent of CT skills in the following areas: analyzing relevance, evaluating sources, and using evidence to formulate an argument. Additionally, a significant and strong correlation is evident between the level of knowledge of the MELCs and the previously mentioned constructs of CT skills. In conclusion, students’ knowledge of the MELCs significantly influences their perception of the MELCs' importance in enhancing their CT skills. When students have a thorough grasp of a particular competency, they are more inclined to utilize it in their critical thinking processes. Hence, it is recommended to consider alternative research methods, such as longitudinal studies, to track students’ development of CT skills over time, as they gain deeper knowledge of the MELCs. Furthermore, employing qualitative research approaches to delve deeper into the connections between knowledge of the MELCs and CT skills could be beneficial.

Authors: Patulin Elvis , Degamon Louella , Borja Emmylou , Vasquez Ma. Crisanta
Published: May 2024

Educational institutions strive to produce graduates who are competent and competitive both domestically and globally. This graduate tracer study investigated the employment outcomes of graduates from the College of Teacher Education (CTE) and Graduate School (GS) Programs from SY 2016-2022. Data collection methods included Google forms, surveys, and phone calls. Of the 2846 CTE graduates, 2491 (87.75%) were traced, and of the 659 GS graduates, 550 (83.45%) were traced. Findings revealed that CTE graduates were predominantly single females aged 24 or younger, who typically began working as permanent teachers at the Department of Education (DepEd) 2-3 years post-graduation, earning a base salary of P15,000–25,000. They generally served in these roles for 4-6 years. Conversely, GS alumni were primarily married men in their 30s, employed in permanent supervisory or managerial roles at DepEd, with monthly earnings between P25,000 and P50,000. Graduates reported that their university degrees were economically relevant and provided significant financial advantages. CTE graduates indicated that job satisfaction was more influenced by workplace interactions and environment than salary. The study suggests enhancing the use of social media to encourage graduate participation in tracer studies and recommends ongoing professional development for faculty to improve educational programs and prepare graduates with highly employable skills. Addressing job satisfaction disparities may require targeted interventions to improve educational programs, expand career development opportunities, and foster supportive work cultures tailored to each graduating class's needs.
SUITABILITY OF CONTEMPORARY PUBLIC LIBRARY SPACES TO USER NEEDS AND PURPOSES: A CASE STUDY OF ERZURUM
Authors: Yalçın İrem Cansu , Sipahi Serkan
Published: May 2024

The library is a societal institution that hosts printed and electronic information sources and facilitates access to these resources when needed. One type of library, public libraries, is an important institution for the education and development of society. Public libraries serve as places where individuals, regardless of age and level, can benefit from library services free of charge, borrow and read books, as well as venues for various social and cultural activities such as conferences, exhibitions, and presentations. In this regard, why public libraries are generally preferred by users has been a subject of curiosity. The changing technology and lifestyle over time have also changed the purposes of library use and users' expectations from the library. The aim of this study is to determine the purposes of use of public libraries today by identifying the purposes of use of libraries. In this context, the "Erzurum Ismail Saib Sencer Provincial Public Library" and "Kazim Karabekir Public Library" in Yakutiye district of Erzurum were selected as the study area. Face-to-face survey was conducted with a total of 110 library users in two libraries, and 100 surveys were evaluated. The survey form was prepared with multiple-choice and Likert scale questions. The data obtained from the survey were analyzed using the SPSS 23 program. Frequency, percentage distribution, and arithmetic mean values were used in the evaluation of the data. In light of the obtained data, the relationship between the areas occupied by library sections within the building and the purposes of use by the public was analyzed. As a result of the evaluation, recommendations were made on which areas of the library should be developed and in which areas the public should be directed more based on the needs of the users.

This paper extends known results of second and third order recursive sequences through extensive formulations of properties of the roots of their characteristic equations, some are old but most are new. They are applied to novel studies of $\sum_{n=0}^{\infty}{\frac{a_{mn}}{10^{n+1}}, \ m=1,2,3}$, including their convergence criteria, and applied to many standard sequences, as particular cases of a generic $\left\{a_n\right\}$. The detailed development of the algebra of the pertinent theorems, and their associated lemmas and corollaries, should open up new vistas for interested number theorists with the concluding results on series values.
Foro privilegiado: a linha tênue entre a democracia e a obstrução da justiça
Authors: Elias Fernando Lopes Ferraz , Lemos Luiz Felipe Melo
Published: May 2024

Este artigo tem como objetivo discutir o tema do foro privilegiado, de forma a entender profundamente quais são as condições para a aplicação do dispositivo legal e as suas implicações no processo judicial brasileiro. Diante disso, fez-se necessário um estudo entre as causas desse preceito, cujo lineamento visa a evitar que impeditivos políticos afetem mandatos democraticamente constituídos, e os efeitos legais do dispositivo, avaliando assim a sua relevância e eficácia no direito brasileiro. Destarte, ao julgar os casos relativos à operação Lava Jato, desde o ano de 2017 os ministros do Supremo Tribunal Federal mostraram-se rigorosos ao aceitar ou não processos relativos a agentes públicos – que detinham o direito ao foro por prerrogativa de função – tendo sidos rejeitados 8 dos 20 inquéritos apresentados à segunda turma, corroborando assim a jurisprudência ao entendimento do tema. Nesse contexto, a análise proposta parte de uma perspectiva crítica que tem como pano de fundo as normas constitucionais que sustentam a democracia. Para tanto, foi realizado um levantamento bibliográfico sobre as origens do dispositivo no Direito brasileiro. Buscou-se também na doutrina e na jurisprudência embasamento para uma reflexão sobre o princípio fundamental da isonomia e a concretização da justiça. Obteve-se como resultado que, sendo faculdade eminente de determinados cargos políticos, o foro por prerrogativa de função cumpre o objetivo de evitar com que prisões arbitrárias interrompam o mandato daquele que está em função pública, que usufrui desse dispositivo; contudo, o amparo aplica-se ao exercício do cargo, e não a quem está trabalhando em função dele – como se tem no imaginário coletivo. O fato de alguns políticos terem se valido do foro por prerrogativa de função não descaracteriza na atualidade a sua importância e muito menos faz com que sua aplicação torne desigual a sociedade brasileira.

Authors: Tiwari Nikhil , Kashyap Parag Jyoti
Published: May 2024

The urban growth refers to the movement of people from rural areas to urban areas, where there is a higher level of human population, economic activity, infrastructure, and significant expansion of land use. Urban growth is closely related to urbanization. In the National Capital Region (NCR), unplanned growth is one of the main problems. These obstacles limit the prospects for economic expansion. So, the study area of this research is the NCR of India. The study is based on the growth of urban areas from 1901 to 2011. The data is taken from the Census of India, Registrar General, and Census Commissioner, New Delhi. It has counted the total towns and population in Delhi, NCR, since 1901 and 2011. The District Census Handbook has been used for the collection of urban population and total population data for that district. Google Earth Pro has been used for the kml format of towns. ArcGIS 10.7 software has been used for mapping purposes. The number of towns has increased from 1901 to 2011. There have been found 182 towns in 2011. The towns also show positive and negative growth from 1901 to 2011. The maximum growth of towns was found after the liberalization period. The maximum growth of towns has been found in the Uttar Pradesh sub region. And most of the towns have transformed into urban regions.

Climate change has a significant impact on both physical and social components of the environment. Every component of the environment has been suffering the impacts of climate change. All components of the environment are interrelated through the exchanging of energy and matter; hence they actively interact. Major components of the environment like the biosphere, lithosphere, atmosphere, and hydrosphere are open systems to impact climate change. This paper describes the major impacts of climate change on major components of the environment. This study investigated the current state, wide-range global research trends, and different concerns on the impacts of climate change on the sustainable tourism. Global climate change represents a grand challenge for society, one that is increasingly influencing tourism sector investment, planning, operations, and demand. This study synthesized a total of 36 studies on climate change by sourcing published material from the review that was performed in indexed databases namely Dimensions, Web Science, Elsevier Scopus, and Google Scholar. Therefore, the study found that human beings are the major contributors to climate change through anthropogenic greenhouse gas emissions that worsened during the Green Revolution. Climate change outcomes through the loss of valuable ecosystem goods and services, degrading the most of keystone species sites. In other ways, loss of biodiversity, changes in atmospheric composition, changes in chemical reactions in soil, changes in water quality, availability, and hydrologic cycles, and frequent occurrence of extreme weather conditions. Of course! The effects of climate change are wide-ranging and diverse, impacting many areas and facets of daily life. Therefore, this study recommends implementing carbon pricing mechanisms to internalize the costs of greenhouse gas emissions and enforcing stringent environmental regulations and standards to limit emissions and pollution. Support global efforts and agreements to combat climate change, such as the Paris Agreement.

Adolescents serve as the foundational resources and future citizens of the nation. India boasts the highest number of adolescents globally, with a staggering count of 253 million individuals falling between the age range of 10 to 19 years, while Assam is ranked thirteenth among the many states and Union territories in India, with a total adolescent population of 65,60,308. During the stage of adolescence, there is a notable surge in growth. With this background, the present study was carried out to study and compare the nutritional status of rural and urban adolescents of the Kamrup-metropolitan district of Assam. Based on the purposive sampling technique, a totalof 200 adolescents were selected. A standardised pre-tested questionnaire was developed to collect information on somatic status and dietary intake. Findings revealed that the majority ofindividuals in both Urban and Rural areas have a BMI of less than 18.5, but the prevalence wasslightly higher in the rural group (56.0%) compared to the Urban group (53.0%). Urban respondents (25.4 cm, 11.28 mm) had a slightly higher mean MUAC and TSF than rural respondents (23.7 cm, 11.19mm). There is a notable difference in the amount of nutrients consumed by adolescents compared to the Recommended Dietary Allowance (RDA). Energy intake is below the recommended levels, with adequacy percentages varying from 78.6% to82.4%, indicating a critical area of concern. Conversely, Visible fat intake is above RDA, ranging from 110.8% to 118.2%, highlighting potential overconsumption in this category. Adolescents were observed to have deficiencies in vitamins A, C, and folic acid compared to the Recommended Dietary Allowance (RDA).

Published: May 2024

Colletotrichum gloeospoiodes causing anthracnose is an important fungal disease of yard long bean infecting leaf, stem, petiole, flower and pod leading to significant yield loss. New generation fungicides viz. strobilurins and triazoles are widely used in the management of the disease. Piriformospora indica is a widely used beneficial root endophytic fungus that suppresses plant diseases in addition to enhanced growth promotion. The present study was outlined in completely randomized design (CRD) to test the compatibility of P. indica with the new generation fungicides commonly used in managing yard long bean anthracnose by poison food technique in petri dishes and broth media and by calculating the percentage of chlamydopsore germinated. The results revealed that P. indica was compatible with strobilurins, combination fungicides of strobilurins and triazoles, carbendazim and pencycuron upto 90 per cent till 350 ppm in poison food and broth experiments. Moreover, germination of the chlamydospores was significant in number in these fungicides. But, triazole fungicides completely inhibited the mycelial growth and chlamydopsore germination of P. indica. Thus, from the present experiment it was clear that P. indica is compatible with strobilurins and combination fungicides.

It is grown in large scale by people in farm forestry and agroforestry programme and also by various agencies. To understand the characteristics of seeds and the quality of seedlings raised from seeds of selected teak clones, an investigation was carried out. Fruits were collected from 25 clones of teak grown at Silviculture Research Station, Koshala, Angul, Odisha (India) and tested at College of Forestry, Odisha University of Agriculture & Technology, Bhubaneswar (India). Experiments were carried out under Completely Randomized Design with 3 replications. Significant variation in fruit characteristics such as fruit length, fruit width, 100 fruit weight, number of seeds per fruit, fruit viability and germination percent was observed. Fruit length varied from 1.08 to 1.57cm and ORANP-4 produced longest fruit while MHALA-7 had minimum value. Fruit width differed from 1.20 to 2.58cm and the highest width was recorded in ORAN-1 (1.58 cm) and lowest in MHALA- 7. Weight of 100 fruits ranged from 34.28 to 56.64g and ORAN-1 recorded maximum fruit weight which was at par with MHALP-9 (54.23 g) while ORPUB -13 registered the minimum value which statistically similar to MHALA-7.  Number of seeds per fruit varied from 3.10 to 4.00. Fruit viability varied from 47.56 to 70.38% and ORAN-4 excelled in viability and remained statistically at par with ORPUB-23, MHALA-9 and ORANR-6. Germination percent of fruit varied from 30.5 to 49.50% and ORANP-4 recorded maximum germination percent, but it was statistically similar to MHALA-9 and ORANR-6. The growth and quality of seedlings raised from the open pollinated seeds of clones also exhibited significant difference. MHALA-9 excelled over others with regard to collar diameter, height, number of leaves, shoot weight, root weight and quality of seedling in 15 month of assessment in nursery. It recorded seedling quality index of 16.41 at the age of 15 month.

Published: May 2024

The mango hopper, scientifically known as Amritodus atkinsoni L., is a very destructive insect that poses a significant threat to mango trees in Eastern Uttar Pradesh. Experiments were done to study the seasonal abundance and the impact of abiotic variables on the occurrence of A. atkinsoni on various mango cultivars, including Dasheri, Sindhu, Amarpali, and Langra, at Vindhyavasini Park (Mango orchard) in DDU, Gorakhpur University Gorakhpur. The adult mango hoppers began to appear when the panicles emerged between the 40th and 20th weeks of the Southwest monsoon in 2022-2023. The highest population of mango hoppers was observed on the Dasheri variety during the 14th week of the season, while the lowest population was observed during the 42nd week. The Amrapali variety had a somewhat lower incidence of mango hoppers, with the highest population observed during the 4th, 7th, and 8th weeks, and the lowest population observed during the 40th week. Abiotic conditions, including maximum temperature (X1), minimum temperature (X2), morning relative humidity (X3), evening relative humidity (X4), and rainfall (X5), significantly influenced the hopper population's impact. The population of hoppers had a negative and significant relationship with morning relative humidity (r = -0.65** to 0.34*) and evening relative humidity (r = -0.40* to -0.21). On the other hand, there was a significant positive correlation between the hopper population and mean maximum temperature (r = 0.28 to 0.09) and minimum temperature (r = 0.17 to – 0.02). Rainfall varied throughout the study period and did not have a significant impact, except for the Dasheri variety.

Collaborative Impact of Inorganic and Organic Fertilizers Coupled with Kappaphycus alvarezii Bio-stimulant on the Quality Characteristics of Wheat (Triticum aestivum L.)
Authors: Toppo Neha , David Arun Alfred , Thomas Tarence , Reddy Iska Srinath
Published: May 2024

The study investigates the influence of different factors on the nutritional content of wheat grains, focusing on crude protein, nitrogen, phosphorus, and potassium contents in grain. Results indicate that varying combinations of factors such as NPK fertilization, farmyard manure (FYM) application, and bio-stimulant usage significantly affect nutrient concentrations in grain. Crude protein content, a vital indicator of grain quality, showed variability across the different treatments, with the highest levels observed in plots receiving RDF @100% + FYM@16.5 t ha-1 + SWBS@1250 ml ha-1. The crude protein content primarily relies on the nitrogen levels. In the research, the findings indicated that the nitrogen content was significant, which, in turn, led to a significant crude protein content. The levels of nitrogen, phosphorus, and potassium content also exhibited fluctuations, with significant interactions observed among various factors. These fluctuations are attributed to differences in nutrient uptake and utilization during the different growth stages of the wheat plant. All three factors can enhance the nutrient uptake facilities through soil as well as plant body, therefore, notably, interactions between NPK, FYM, and bio-stimulants exhibited significant effects on nutrient content, particularly at the 0.05 significance level. The findings underscore the importance of holistic agricultural management in enhancing the nutritional value of wheat grains, with implications for food security and agricultural sustainability.

Today, with the rapid development of science and technology, there are a lot of repetitive labor in people's production and life, and there are many risks when they explore unknown places. To a large extent, the emergence of mobile robots can solve these problems and replace human beings to complete boring tasks and reduce risks. The mobile robot combines the robot with the omnidirectional mobile platform, which greatly increases the activity range of the robot, but the ability of the mobile single robot is difficult to meet the heavy processing tasks and various processes, and the advantages of multi-robot technology are increasingly apparent. Compared with a single robot, it has the advantages of wider task field, strong fault tolerance, strong robustness, low economic cost and flexible distribution.
In this paper, a mobile multi-robot machining platform is designed based on a 6-DOF mobile robot. The mobile robot is composed of an AGV car, a 6-UCU parallel robot and an electric spindle. The three-dimensional model of the mobile multi-robot machining platform established is composed of two isomeric robots, which are symmetrically distributed on the machining platform to lay the foundation for direct coupling. Then the force is added to the mobile multi-robot machining platform in Adams, and the dynamic simulation is carried out to observe the force of each electric cylinder during movement. The modal analysis of the mobile robot was carried out by using ANSYS Workbench software to obtain modal parameters such as natural frequency to verify the rationality of the designed mobile robot.to truly detect the safety hazards. In order to solve these problems, ANSYS (finite element analysis software) is used to analyze the theoretical stress of the 3D structure model, and the theoretical dangerous stress position of the structure is solved. Provide strong data support for the design and development of wind power crane industry in the later stage.

Aims: This paper investigates four different metallic coatings of 17-4PH stainless steel and tests them in seawater as a means of preventing seawater corrosion of turbine upper stage blades..
Study Design: The self-corrosion current densities of the different specimens in the synthetic seawater solution were measured using open circuit, polarization curves, and  electrochemical AC impedance spectra.
Place and Duration of Study: Department Between July 10, 2023,  and August 10, 2023, the Laboratory of the School of Mechanics, North China University of Water Resources and Hydropower (NUWRH).
Methodology: For the working condition of turbine final blades, four different metal coatings based on 17-4PH stainless steel are investigated to simulate the working condition of turbine blades, and electrochemical tests are carried out on the four different specimens in the test solution of synthesized seawater solution. The self-corrosion current densities of the different specimens in the synthetic seawater solution were measured using open circuit, polarization curves, and electrochemical AC impedance spectra.
Results: The results show that the AHP-coated 17- 4PH stainless steel specimens have the lowest self-corrosion current density (color) in the synthetic seawater solution.
Conclusion: Non-invasive This indicates that the corrosion rate of AHP coatings in synthetic seawater solutions is slower than that of TW-7 coatings, sprayed stainless steels, and other stainless steels in the same conditions.
LASER‐Based Reflectometric Surface Analysis of a Glass Melt
Authors: Berg Sania
Published: November 2010

The surface condition of a glass melt, namely its optical properties, has significant influence on the melting process. The surface layer of the melt acts as interface layer between the radiation source and the as radiation sink acting glass melt. All radiation that will heat up the melt first has to pass the melt surface. This is why it is important to keep the surface in a state of high optical transmission. Because no means of measuring the optical properties of a melt surface are available so far, a new approach has been tested out to obtain information about the melt surface using “small angle backscattered laser radiation” and presented in ref.1. The self‐radiation of the melt however is something that complicates optical measurements.

Published: November 2010

Considering the significant influence of the morphology of graphite inclusions on the properties of cast iron it is important to understand the correlation between manufacturing parameters and resulting microstructure. In particular, understanding the effect of alloying elements and inoculants on the formation and growth mechanisms of the graphite particles provides the basis for exact tailoring of the microstructure and thus exact tailoring of effective properties of cast iron. Experimental observations of the three‐dimensional (3D) structure of graphite particles, high resolution chemical analysis of nuclei and other inclusions, as well as quantitative characterization of possible growth mechanisms have confirmed certain existing theoretical models for nodular and flake graphite and provided a comprehensive description of all intermediate morphologies. Precise analysis of the graphite's crystal structure based on target preparation of transmission electron microscope thin foils opens additional possibilities for estimating of the properties of different graphite types.

Titanium implants are well known for their biocompatibility, especially if bioinertness is desired, due to the TiO2 native oxide which is thermodynamically and chemically very stable. One of the major problems with this material involve its inability to induce enhanced cellular adhesion and proliferation on its surface without complicated structural approaches, leading to the possible lack of bone‐implant interfacial interaction and rejection. In order to potentially improve osseointegration of such implants self‐assembled vertical and ordered nanotubular TiO2 arrays were fabricated by electrochemical anodization and were plasma treated under O2, N2, O2 + N2, and He gaseous environments and their properties analyzed by various analytical procedures. Osteoblast bone cells (MC3T3‐E1) were grown on TiO2 nanotube‐arrayed substrates and their proliferation was analyzed and quantified. Oxygen and nitrogen plasma treatments were found to significantly improve the proliferation of the bone cells over the TiO2 nanoarray substrates, with the O2 + N2 combination yielding the most significant improvements. These findings may be explained by the interactions between the cells and the changes in the surface chemistry induced by the O2 and N2 groups introduced by the plasma discharge treatment onto the TiO2 surfaces

DTDST mutations cause a spectrum of diastrophic dysplasia disorders characterized by defects of proteoglycans sulfation. Reduction of sulfate/chloride antiporter activity is manifested by lower sulfate uptake and depends on a combination of mutations in DTDST. We analyzed a family with an autosomal recessive form of bone dysplasia. Three affected brothers from this family are compound heterozygotes for C653S/A715V mutations. We classified their phenotype as a new intermediate form between diastrophic dysplasia and multiple epiphyseal dysplasia, manifested by shortening of stature, metatarsus adductus/club foot, mild brachydactyly, proximally placed thumbs and clinodactyly of the fifth fingers. Radiographs document platyspondyly most marked in the lower thoracic and upper lumbar spine, epiphyseal dysplasia affecting predominantly the femoral heads, widening of the metaphyses, narrow growth cartilage and multilayered patellae. Exaggerated lesser trochanters of femur, that is, “monkey wrench” sign, elevated greater trochanters, thin upper pubic rami, grossly normal carpal/tarsal bones and severe, early onset osteoarthritis were other notable features. © 2010 Wiley‐Liss, Inc.
Timing of hormone therapy and dementia: The critical window theory revisited

Published: November 2010

Objective:

Although previous research has shown that initiation of postmenopausal estrogen hormone therapy (HT) in late life increases risk of dementia, animal studies and some observational studies have suggested that midlife use of HT may be beneficial; however, this has not been rigorously investigated in large population‐based studies. Our objective was to compare HT use in midlife with that in late life on risk of dementia among 5,504 postmenopausal female members of an integrated healthcare delivery system.

Methods:

HT use was determined at midlife (mean age, 48.7 years) from a survey in 1964 and in late life (mean age, 76 years) using pharmacy databases from 1994 to 1998. Risk of dementia diagnosis was evaluated with inpatient and outpatient diagnoses made in Neurology, Neuropsychology, and Internal Medicine from 1999 to 2008. Cox proportional hazard models were used to examine effects of HT use at different times on dementia risk with adjustment for age, education, race, body mass index, number of children, and comorbidities.

Results:

A total of 1,524 women (27%) were diagnosed with dementia during the follow‐up period. Compared to women never on HT, those taking HT only at midlife had a 26% decreased risk (multivariate adjusted hazards ratio [aHR], 0.74; 95% confidence interval [CI], 0.58–0.94 ), whereas those taking HT only in late life had a 48% increased risk (aHR, 1.48; 95% CI, 1.10–1.98), and women taking HT at both mid and late life had a similar risk of dementia (aHR, 1.02; 95% CI, 0.78–1.34 ).

Interpretation:

These findings suggest that use of HT in midlife only may protect against cognitive impairment, whereas HT initiation in late life could have deleterious effects. ANN NEUROL, 2010

Authors: Szpilman Alex M. , Carreira Erick M.
Published: November 2010

The systematic modification of natural products through diverted total synthesis is a powerful concept for the systematic modification of natural products with the aim of studying mechanistic aspects of their biological activity. This concept offers far‐reaching opportunities for discovery at the interface of biology and chemistry. It is underpinned by the power of chemical synthesis, which manifests itself in the ability to modify structure at will. Its implementation, when combined with innovative design, enables the preparation of unique mechanistic probes that can be decisive in differentiating and validating biological hypotheses at the molecular level. This Review assembles a collection of classic and current cases that illustrate and underscore the scientific possibilities for practitioners of chemical synthesis.
