WHAT IS THE BEST PHASE OF MANAGING INTER-FIRM RELATIONSHIPS IN SUPPLY CHAINS?
Authors: İNCEKARA Mustafa
Published: May 2023

The level of innovation in a product should determine the best stage at which inter-relationship collaboration in a supply chain is engaged in developing new products. Unfortunately, there is a lack of consensus in the relevant literature on the specific stage for inter-relationship collaboration in a supply chain in transformative technologies. For example, the inter-relationship collaboration in a supply chain becomes significant at a later stage of disruptive innovation when the most cutting-edge product or technology must be marketed. On the other hand, inter-relationship collaboration in a supply chain should be included in the innovation process at a much earlier stage to ensure a more comprehensive supplier engagement. Several researchers have examined suppliers' role in product innovations; nevertheless, none of the published supplier integration models are directly connected to the issue of at what point suppliers need to be integrated into the product innovation process. Therefore, this article aims to propose a blueprint for inter-relationship collaboration in a supply chain during product innovation phases, with an emphasis on the stage of involvement applicable to both incremental and disruptive innovation. In addition, various aspects concerning inter-relationship collaboration in a supply chain in the different phases of product invention are subjected to an in-depth investigation.

Немыслимое: «перестройка» как заговор
Authors: Ильинский Игорь Михайлович
Published: May 2023

Статья известного социального философа, ректора Московского гуманитарного университета И. М. Ильинского представляет одну из вступительных глав книги о Перестройке, над которой автор работает многие годы. Книга в настоящее время готовится к изданию. В ней автор опровергает взгляды, согласно которым СССР распался в силу внутренних противоречий, и показывает, что главной причиной распада страны стал заговор высших лиц государства (М. С. Горбачева, А. Н. Яковлева, Э. А. Шеварднадзе). Суть этого заговора состояла в том, чтобы под видом демократизации общества осуществить разрушение «тоталитарного» государственного строя СССР, что, как показывает И. М. Ильинский, совпадало с задачами руководителей Соединенных Штатов Америки. Для подтверждения своих выводов автор обращается к обширному историческому, историко-архивному и биографическому материалу.

Русская идея и Русский мир: философско-культурные параллели
Authors: Кот Юрий Владимирович
Published: May 2023

В статье обосновывается тезис о том, что идея Русского мира органически связана с Русской идей. Их соотношение с авторской позиции выглядит следующим образом: философское понятие «русская идея» является внутренним духовным содержанием геокультурного понятия «Русский мир». Современный концепт Русского мира не может ограничиваться лишь геополитическими параметрами, но должен включать в себя историософский и сотериологический опыт русской религиозной философии, сконцентрированный в понятии «русская идея». Предлагаемая формула русской идеи предстает как нравственный синтез историософии и сотериологии и дает необходимые мировозренческие основы Русского мира. Акцент исключительно на историософии — это геополитика; акцент исключительно на сотериологии — это монашеский идеал, далекий от историко-культурных и общественно-политических вопросов современности. Только нравственный синтез историософии и сотериологии может в наиболее полной мере раскрыть духовный потенциал русской идеи. В статье рассматриваются основные историософские и сотериологические концепты русской идеи (историософский и сотериологический архетипы) в классическом и современном изводах и намечаются пути их интеграции в историко-культурное и общественно-политическое пространство Русского мира.
Data dynamics of angiogenesis visualization instrumental methods in patients with psoriasis during methotrexate therapy: Clinical and prognostic value of dermatoscopy and ultrasound dopplerography
Authors: Pritulo Olga A. , Petrov Alexey A. , Brodavkin Dmitri V.
Published: May 2023

BACKGROUND: Pathological angiogenesis is one of the important pathogenetic links of psoriasis. At the same time, the prognostic significance of instrumental methods for studying the severity of angiogenesis in psoriatic plaques remains poorly understood.
AIM: Clinical assessment of the correlation between the dynamics of angiogenesis parameters (morphometric parameters of vascular glomeruli and Doppler blood flow in the skin and nail bed) and indicators of the methotrexate clinical efficacy during 12 months of therapy.
MATERIALS AND METHODS: The work is based on the clinical data analysis of 82 patients with moderate and severe psoriasis vulgaris in the acute stage, who were prescribed methotrexate after initial examination. Patients underwent Doppler ultrasound examination of the skin in psoriatic plaques area and digital dermatoscopy to study the characteristics of vascular angiogenesis loci before treatment and at 1, 3 and 12 months of methotrexate therapy.
RESULTS: As a result of comparative correlation analysis of dermatoscopy and ultrasonographic Dopplerography indicators dynamics and psoriasis clinical index values during the treatment of patients with methotrexate, moderate and strong correlations were established between the values of the average diameter of the vascular glomerulus and the degree of increased blood flow in psoriatic plaque area after 1 month of methotrexate treatment and the values of PASI at 3, 6 and 12 months from the start of treatment (r=0.540.76, p=0.0020.005), as well as between the mean vascular glomerulus diameter values and the degree of skin blood flow increase after 3 months and PASI and BSI indices after 6 and 12 months (r=0.360.74, p=0.0010.036). Disappearance of Doppler signals in psoriatic plaques skin and decrease in vascular glomeruli average diameter after 1 month from the start of therapy in 1.76 [1.38; 2.30] and 1.30 [1.38; 2.30] times increase the probability of achieving clinical improvement after three months of methotrexate treatment. The correlation coefficient between the degree of NAPSI reduction after 6 and 12 months of treatment and the dynamics of Doppler blood flow in the nail bed and resistance index of arterial vessels in the nail bed after three months from the start of treatment varied from 0.53 to 0.73.
CONCLUSIONS: The dynamics of instrumental methods indicators for studying pathological angiogenesis correlates with the probability of achieving clinical improvement in psoriasis symptoms during systemic methotrexate therapy.
Skin mucormycosis in dermatological practice: Dangerous coinfection during the COVID-19 pandemic (current state of the issue)
Authors: Burova Sofia A. , Taganov Alexey V. , Kashtanova Anna A. , Gorbacheva Yulia V.
Published: May 2023

The coronavirus SARS-COV-2 pandemic has caused an increase in the incidence of the population and significant losses that have claimed more than 6.8 million lives worldwide. In recent years, secondary microbial co-infections have caused serious concern: influenza, tuberculosis, typhoid fever, mucormycosis, etc. At the beginning of the catastrophic wave of coronavirus disease, there were reports of a rare but deadly mucormycosis, which quickly spread throughout the world. Currently, the relevance of this complication has increased significantly due to the pandemic of a new coronavirus infection, immunosuppression, diabetes mellitus and the massive use of glucocorticosteroids for the treatment of COVID-19.
It is proposed to revise diagnostic strategies to detect secondary co-infection. First-line therapy is amphotericin B in combination with surgery. Delaying antifungai therapy and surgical excision of diseased tissue increases mucormycosis-related mortality, requiring a high level of medical skill in both diagnostic and therapeutic aspects.

Published: May 2023

The pandemic caused by a new strain of SARS-CоV-2 coronavirus has swept the whole world, however, despite the developed strategic directions for the treatment of coronavirus infection and intensive research in all countries, effective methods for treating this severe pathology have not yet been created. The list of drugs against COVID-19 practically does not use compounds that affect the renin-angiotensin system, in the functioning of which the ACE2 coronavirus binding receptor plays a central role. It is assumed that the virus, causing a decrease in the density of ACE2 receptors, leads to disruption of RAS activity. This review presents current research on the response of the immune system to infection with the SARS-CoV-2 virus, describes adaptive and innate cellular mechanisms, and describes a number of predictors of severe COVID-19.
To write this review, a search was made in the PubMed database and the scientific electronic library eLibrary.ru. The selection of articles was carried out manually with the main goal of synthesizing data and describing the mechanisms of influence of SARS-CoV-2 on the renin-angiotensin system, and, as a result, on the activation of the adaptive and innate immune response. This review includes 53 publications, including methodological recommendations of the Ministry of Health of the Russian Federation, data from ongoing clinical trials and patents. Data from selected scientific sources were structured and visualized.
Prospects of pharmacological regulation of aquaporin function in CNS diseases
Authors: Ponamareva Natalia S. , Novikov Vasiliy E. , Pozhilova Elena V.
Published: May 2023

The review analyzes the results of scientific research on the role of aquaporins in the pathogenesis of CNS diseases and the possibility of their pharmacological regulation.
Aquaporins (AQP) are proteins involved in the transmembrane transport of water and other substances. They form the water channels of cell membranes and are widely represented in various mammalian cells, including the membranes of human brain and spinal cord cells. To date, about 300 types of proteins of the aquaporin family have been discovered, of which 13 (AQP0AQP12) have been identified in human cells. Localization of different types of AQP in CNS structures, their functional activity and involvement in the development of CNS diseases differ. There are mainly three types of AQPs in the central nervous system: AQP1, AQP4 and AQP9. The results of scientific research indicate the most important role of AQP in maintaining water-salt homeostasis and ensuring physiological processes in the central nervous system, and also confirm the role of AQP in the pathogenesis of a number of diseases of the central nervous system (cerebral edema of various genesis, invasion of tumor cells and the formation of peritumorous edema, in the development of autoimmune diseases opticomyelitis, Alzheimers disease). Pharmacological regulation of the functional activity of aquaporins can influence the course of these diseases. Therefore, there is a natural interest in drugs that can change the expression of AQP.
Proteins of the aquaporin family provide transmembrane transport of water and play an essential role in the development of pathological conditions of the central nervous system. They can be potential targets for pharmacological effects in a number of diseases of the central nervous system. The search and study of drugs affecting the expression and functional activity of AQP is pathogenetically justified and is a promising direction in the development of pharmacotherapy strategies for cerebral edema, malignant brain tumors and other CNS diseases.
Effect of intragastric administration on the morphology of laboratory rats’ gastrointestinal tract
Authors: Gushchin Yaroslav A. , Makarova Marina N. , Shabanov Petr D.
Published: May 2023

BACKGROUND: In preclinical studies on laboratory animals, oral administration with special probe for test substances is very in demand. Most studies are devoted to the psychophysiological and clinical-biochemical reaction of the animals body to this effect, but extremely few studies consider the effect of the manipulation itself on the development of pathology in the tissues of the gastrointestinal tract associated with the inevitable mechanical impact of the probe on the mucous membranes.
AIM: To identify pathological changes in the organs of the gastrointestinal tract of laboratory rats that are associated with the effects of intragastric administration of the tested substances, and compare the data obtained with the frequency of spontaneous diseases.
MATERIALS AND METHODS: The data of pathomorphological observations obtained from Wistar rats involved in the course of scientific work carried out at NPO Dom Pharmacy in the period from 2018 to 2021 were used. 1400 sentinel animals were analyzed, and the same number of intact rats. Intact animals were gavaged with a control substance (distilled water) for 14 days.
RESULTS: In less than 5% of clinically healthy animals, inflammatory diseases of insignificant intensity and prevalence in all parts of the intestine can be detected. As a result of the anipulation of intragastric administration, an almost twofold increase in the number of cases of catarrhal esophagitis and gastritis, erosive and ulcerative lesions of the mucous membrane of the esophagus and stomach in its glandular part and hyperkeratosis in its non-glandular part was noted.
CONCLUSIONS: The type and frequency of occurrence of the background pathology of the gastrointestinal tract of laboratory rats were determined. It has been proven that repeated traumatization of the mucous membrane associated with mechanical contact of a solid metal probe with the epithelium provokes the development of inflammatory diseases of the esophagus and stomach, without affecting the underlying parts of the intestine.

BACKGROUND: Exposure to acute or chronic stress contributes to the occurrence of various disorders of the central nervous system, psycho-emotional sphere, as well as increases the risks of development of various forms of addiction.
AIM: The aim of the study is analyze the influence of maternal deprivation on voluntary alcohol consumption in adolescents and to determine the degree of the signs of compulsive behavior in experimental animals.
MATERIALS AND METHODS: Thirty male Wistar rats were taken in the research. A maternal deprivation model was carried out from day 2 to day 12 of the postnatal period (MD). Compulsivity (compulsive tendency) was evaluated in the ball burial test. Voluntary alcoholization with 10% ethyl alcohol solution in a two-bottle test was employed. Level of progesterone in blood plasma was determined by enzyme- immune analyses.
RESULTS: Changes in the level of progesterone in blood plasma in MD and control group of animals were detected. In the test of two bottles 10% of ethanol solution presented on days 2 and 3, statistically significant differences in consumption were determined in contrast to the control group. In the test of balloon diapering, MD group of animals showed a statistically proved significant increase in compulsiveness both before the beginning of voluntary alcoholization and on day 3 from the start.
CONCLUSIONS: The increase in compulsivity and voluntary ethanol consumption was significantly higher in the MD group, that is comparable to the increased level in blood plasma progesterone samples.

Abstrak. Kedelai adalah salah satu tanaman pangan kaya protein nabati dan kandungan gizi yang baik. Tanaman kedelai juga dapat mengfiksasi nitrogen (N) yang ada di udara dengan bantuan bakteri rhizobium dan mikroorganisme tanah lainnya. Unsur N di dalam tanah sangat penting bagi pertumbuhan tanaman. Salah satu sumber energi bagi tanaman adalah nitrat tanah (NO3-) yang merupakan bagian dari proses siklus N. Salah satu upaya penyediaan hara N di dalam tanah adalah dengan memanfaatkan limbah pertanian yang disebut dengan biochar. Biochar merupakan arang hayati dengan proses pembakaran secara pirolisis atau oksigen terbatas. pemberian beberapa jenis biochar juga dapat mencegah terjadinya emisi gas rumah kaca karena biochar dapat menyimpan karbon (carbon stroge) yang bersifat resisten di dalam tanah. Pemberian pupuk N ke dalam tanah disamping membantu pertumbuhan tanaman, namun juga meningkatkan terjadi emisi gas rumah kaca (N2O) melalui pengaruh tidak langsung terhadap faktor fisika-kimia dan biologi tanah. Abstract.

Soybean plants can also fix nitrogen (N) in the air with the help of rhizobium bacteria and other soil microorganisms. The element N in the soil is very important for plant growth. One of the energy sources for plants is soil nitrate (NO3-) which is part of the N cycle process. One of the efforts to provide N nutrients in the soil is to utilize agricultural waste called biochar. Biochar is biological charcoal with a pyrolysis combustion process or limited oxygen. the provision of several types of biochar can also prevent greenhouse gas emissions because biochar can store resistant carbon (carbon stroge) in the soil. The application of N fertilizers into the soil in addition to helping plant growth, but also increases the emission of greenhouse gases (N2O) through indirect effects on soil physico-chemical and biological factors.

Abstrak. Garis pantai merupakan batas antara air laut dan daratan. Batas ini selalu berubah dengan sangat dinamis dan saling berintersaksi, perubahan secara sementara seperti adanya pasang surut maupun perubahan akibat abrasi dan akresi dalam kurun waktu yang lama. Perubahan garis pantai disebabkan oleh proses alami maupun aktivitas manusia dalam memanfaatkan kawasan pantai guna memenuhi kebutuhannya (Niya, et al., 2013). Adapun tujuan penelitian ini yaitu untuk mengetahui terjadinya perubahan garis pantai, lebar perubahan garis pantai dan faktor penyebabnya. Analisis perubahan garis pantai diawali dengan pengumpulan data skunder, yaitu data citra landsat 5, 7 dan 8. Kemudian dilanjutkan dengan analisis menggunakan tools Digital Shoreline Analysis System  (DSAS). Hasil analisis menunjukan bahwa terjadi perubahan garis pantai dalam kurun waktu 20 tahun terakhir. Sebagian besar perubahan garis pantai mengalami abrasi dan hanya sebagian kecil yang mengalami akresi. Abrasi terjadi secara alami disebabkan oleh energi kinetik air laut sedangkan akresi terjadi di kawasan terbangun, yaitu pembangunan infrastruktur seperti di pelabuhan, dermaga dan kawasan-kawasan yang dibangun Seawall.Abstract. The coastline is the boundary between sea water and land. This boundary is always changing very dynamically and interacting with each other, temporary changes such as tides and changes due to abrasion and accretion over a long period of time. Changes in coastlines are caused by natural processes and human activities in utilizing coastal areas to meet their needs (Niya, et al., 2013). The purpose of this study is to determine the occurrence of shoreline changes, the width of shoreline changes and the factors causing it. The analysis of shoreline changes begins with the collection of secondary data, namely Landsat 5, 7 and 8 imagery. Then proceed with analysis using the Digital Shoreline Analysis System (DSAS) tools. The results of the analysis show that there has been a change in the coastline in the last 20 years. Most of the changes in the shoreline undergo abrasion and only a small part undergoes accretion. Abrasion occurs naturally due to the kinetic energy of seawater while accretion occurs in built-up areas, namely infrastructure development such as ports, docks and areas built by Seawall.

The infiltration rate is the rate at which water enters the soil and depends on soil conditions. Robusta coffee plantations certainly have several levels of plant age, namely from young age to adult age. Mature plant roots affect the pores in the soil. Plant roots in the soil are not only increasing the activity of microorganisms, but the pores of the soil are also getting bigger so that the opportunity for water to enter the soil is also greater. This study examines the infiltration rate at several ages of Robusta coffee plants. This research was carried out at the Robusta Coffee Garden, Bintang Bener Village, Ketambe District, Southeast Aceh Regency. This study uses a Double Ring Infiltrometer and calculations using the Horton model. The results of this study indicate that the highest infiltration rate is at the first point at the age of 9 months, the initial infiltration rate (f0) is 24 cm hour־¹ and the constant infiltration (fc) is 8.4 cm hour־¹.

Published: May 2023

Pohon pinus termasuk dalam famili Pinaceae memiliki sebaran yang luas mulai dari bumi belahan utara hingga selatan dan mencakup hampir 120 spesies. Pinus yang tumbuh asli di Sumatera terbagi menjadi tiga galur, yaitu: Aceh, Kerinci, dan Tapanuli. Galur Aceh dikenal sebagai populasi terbesar di antara ketiganya dan tumbuh secara alami. Umumnya tumbuh di dataran tinggi atau lebih dari 1.000 meter di atas permukaan laut (mdpl). Ketinggian tempat (altitude) sangat berpengaruh terhadap ketinggian dan umur tanaman. Ketinggian tempat dipengaruhi oleh iklim terutama curah hujan dan temperatur udara. Tinggi tempat berpengaruh terhadap temperatur udara dan intensitas cahaya (Nurmasari dan Djumali, 2010).) Metode yang digunakan pada penelitian ini purposive sampling. Data yang diperoleh dari dua ketinggian tempat yang berbeda ditulis di excel kemudian di uji dengan Statistik dengan uji Independent samples t-test, uji ini untuk mengetahui perbedaan dari dua populasi/kelompok data. Hasil uji statistik menunjukkan bahwa perbedaan altitude dapat menyebabkan perbedaan yang signifikan (p 0.05) pada 3 parameter yaitu tinggi pohon (m), tinggi cabang pertama dari tanah (cm), diameter batang (cm), jumlah cabang (unit). Sedangkan, perbedaan altitude tidak menyebabkan perbedaan yang signifikan (p 0.05) pada 2 karakter morfologi yaitu panjang strobilus betina (cm), dan diameter strobilus betina (cm)
