Authors: Bazhenova O. P. , Barsukova N. N
Published: October 2021

According to the study of summer phytoplankton of the Ob River, 153 new species and intraspecific taxa(SIT) of algae from 8 divisions were found, including Cyanoprokaryota – 14, Dinophyta – 2, Chrysophyta – 17, Xantophyta –6, Euglenophyta – 34, Bacillariophyta – 2, Chlorophyta – 72, Charophyta – 6. New taxa are dominated by small-cell greenalgae, phytoflagellates and non-heterocyst cyanoprokaryotes. The intensive succession of the phytoplanktocenosis speciescomposition and the taxonomic structure of the new SIT algae are signs of anthropogenic eutrophication.

Authors: Belous V. N.
Published: October 2021

The article deals with the issues of localization and landscape preference of Pyatigorye’s phytocenoses ofthe upland steppes. The syntaxonomic composition of the steppe communities on the studied territory, as well as the typesof the floristic core, are indicated. It consists of graminoids, mesothermal perennials of long vegetation, caudex herbs ofan ephemeroid type of development, and bulbous geophytes. The features of communities, the reasons for their spatialdifferentiation are revealed. The distribution of species by relief elements and communities was determined expertlyon the basis of field studies (2018–2021). It was concluded that the main factors determining the diversity of uplandsteppe vegetation in the studied region are the nature of the destruction of the parent rock and soil development, the levelof insolation and ecotope moisture. The steppe communities of Pyatigorye on carbonate underdeveloped thin skeletalchernozems are distinguished by their species richness. In most of them, Stipa pulcherrima plays a high phytocenotic role,as well as other sod and dense bush grasses. Species of the “southern” steppe and Caucasian forbs, incl. petrophytes playsignificant role. The communities include rare species in the region: Astragalus brachycarpus, Dictamnus gymnostylis,Leopoldia tenuiflora, Paeonia tenuifolia, Iris pumila, I. aphylla, Orchis tridentata, Asphodeline taurica, Lamyra echinocephala,Linum tauricum, Onosma caucasica, Cerasus incana, Cephalaria coriacea. The studied representative communities areimportant for the conservation of the biological diversity of the region. Habitats of rare species are of scientific importanceand are of nature conservation interest.

Diversity of the hybrid forms between Siberian stone pine and Siberian dwarf pine
Authors: Vsilyeva G. V.
Published: October 2021

Siberian stone pine (Pinus sibirica) and Siberian dwarf pine (P. pumila) are Russian five-needle pines withdifferent life forms, namely upright tree and prostrate tree, respectively. Hybridization of the species was considered in thepaper from the point of view of the habitus of their natural hybrids. In early studies, it was always noted that the hybridswere intermediate in comparison with the parental species. Crown structure in hybrids are largely determined by twomain factors. These are deflection of the tree stem from the vertical axis and the selectivity of apical dominance. Hybridsgrowing in open places under full lighting conditions are characterized by strictly intermediate growth form. In a forestwhere there is no enough light, hybrid reaches for sun but gradually deviates to the side, which ultimately leads to a branchbreak or even the roots of the entire tree being upturned from the soil. In the mountains, hybrids can form uniform trunkbranches, forming a cup-shaped crown, similar to how it happens in Siberian dwarf pine. Thus, the previously notedintermediate morphology of hybrids represents a series of forms, from almost vertical multi-stemmed trees to pumila-likeones with a cup-shaped crown.

The main task of the expeditions was the search for the following species of natural Siberian flora and theintroduction of live plants and seeds to the Botanical Garden named after acad. A. V. Fomin: Cotoneaster mongolicus.C. neo-popvii, C. tjulinae, which are currently presented in our collection. In addition, long-term phenological observations in the conditions of the north-west of Ukraine allowed to isolate new species from the imported material: C. kyachticus.C. logginovii. They are described in the materials of the XIV and XVII conferences “Problems of botany of Southern Siberiaand Mongolia”. A trip to the lake Zun-Torei was dedicated to the search for C. mongolicus. As it turned out later, under theC. mongolicus mother’s plant, we dug up a plant different from the mother’s plant, to which we gave the name C. logginovii.This article provides materials to identify the parents pair in the formation of this hybrid pitchfork. For this purpose,materials of herbarium collections from the vicinity of the lake were used Zun-Torei experienced local botanists, as wellas personal fees. Comparison of the samples allowed to establish their identity with C. mongolicus, as well as to certify it asone of the parents of C. logginovii. Morphological descriptions of annual shoots leaves, flowers, fruits, seeds of three typesof Cotoneasters: C. megalocarpus, C. mongolicus, C. yakuticus; micrographs of endocarp of bones of the previous speciesand C. logginovii, C. melanocarpus, C. uniflorus are given. The herbarium samples of C. mongolicus collected in the areaof the lake Zun-Torey were analyzed. The material is illustrated with photographs of plants introduced in the north-westof Ukraine (Kiev). The introduction of plants by the method of genus complexes by F. N. Rusanov allowed to create theCotoneaster collection, which includes 200 taxa of the genus. In the Botanical Garden named after acad. A .V. Fomin fromthe flora of Siberia preserved 11 species of Cotoneaster: C. commixtus, C. kyachticus. C laxiflorus. C. logginovii, C. lucidus,C. neo-popovii, C. megalocarpus, C. mongolicus, C. tjulinae, C. uniflorus, C. yakuticus.

Authors: Zvereva G. K.
Published: October 2021

The structure of the chlorenchyma and the spatial forms of assimilative cells are considered in the glumesof spikelets at the xerophytes Cleistogenes squarrosa and Tripogon chinensis and the halophytes Aeluropus intermedius andCrypsis aculeata with C4-photosynthetic metabolism (NAD-ME biochemical group). The structure of the photosynthetictissue of the rachis was also studied in Tripogon chinensis. It is shown that the generative and vegetative organs of chloridoid grasses are similar in the structure of the chlorenchyma, but differ in the degree of its development. In the glumes ofspikelets, it is less developed than in the leaves, and in the rachis, on the contrary, its presence is greater than in the stem.In the assimilatory tissue of generative organs, there is also a wide participation of longitudinally arranged cellular cellsconsisting of small, often numerous sections, which in their size are close to those in the leaves and stems.

Authors: Klimova O. A.
Published: October 2021

This article presents the results of studies of cenopopulations of the Erythronium sibiricum in the disturbedareas of Kemerovo region. Erythronium sibiricum is a rare plant listed in the Red Book of the Russian Federation. To assess the condition of the cenopulations of the studied species in disturbed territories, research was carried out on an oldlimestone quarry (kandyk-sedge birch forest, anthropogenically altered birch-pine forest) and on anthropogenically disturbed meadows. 4 phytocenoses of various compositions have been studied. As a result of research, it was found that inthe kandyk-sedge birch forest Erythronium sibiricum occupies 10 % of the herbaceous cover, in the anthropogenically altered birch-pine forest – 5 %, in anthropogenically disturbed grasslands Erythronium sibiricum occurs singly and makesup less than 1% of the herbaceous cover. Under the forest canopy, the biometric indicators of generative individuals of thisspecies are higher than in meadow communities, where, for example, the length of generative shoots is 6–8 cm less, or generative individuals are absent. No seedlings, senile and dying individuals were found in the age spectrum of Erythroniumsibiricum cenopulations. Reproduction of the species occurs by seed. In the age structure, all cenopulations are left-handed, incomplete, of the normal type.

Published: October 2021

xModern forest shelter belts do not fully protect arable land and most often have a different life state. In theseconditions, the preservation of forest belts, their performance of protective functions in the system of agroforestry andother complex measures remains an urgent task. The studies were carried out in a field-protective forest belt located in thevicinity of the Oktyabrsky village of the Krasnoturansky district of the Krasnoyarsk Territory, where a temporary test plotwas laid using generally accepted methods. The aim of the research was to study the current state of this forest belt by identifying the sanitary state and preservation of the stand and growth rates of Scots pine. Analysis of the current state of thestand showed that the average category of the state of trees is 1.3 points. The stand safety is 44.9%. Pine trees at the age of 28after planting have reached an average height of 11.6 m with an average diameter of 19.1 cm. The forest belt has an optimalopenwork-blown design and is capable of self-renewal naturally. To prevent further degradation of arable leached chernozems in treeless areas of the steppe zone of the Krasnoyarsk Territory, it is advisable to create pine forest shelter belts.

It was investigation on distribution of seven Euro-Siberian plant species on the western borders of their natural ranges in Nizhegorod region. Amygdalus nana L., Cotoneaster melanocarpus Fisch. ex Blytt., Crataegus sanguinea Pall.,Spiraea crenata L. are on the north-west borders. Abies sibirica Ledeb., Larix sibirica Ledeb. et Lonicera caerulea L. are onthe south-west borders. It was ascertained, that Crataegus sanguinea, Larix sibirica et Lonicera caerulea enlarged its rangesat naturalization from cultivation and tinning of forests. Crataegus sanguinea moved on taiga and Larix sibirica moved onforest-steppe. This is analogous their ranges in Siberia. The ranges of Abies sibirica, Amygdalus nana, Cotoneaster melanocarpus and Spiraea crenata remained the same even under the conditions of cultivation. It was supposed, that the reasonof these differences is greater ecological tolerance of first third species. Anthropogenic factors promote reach their natural borders. Moreover, anthropogenic factors can create favorable phytocenotic conditions, but don´t can create favorablephysiographic conditions for others.

Vascular plants– phyto-indicators of geoactive zones in mountains and plains
Authors: Rogozin M. V , Mikhalev V. V.
Published: October 2021

The research was conducted in the Perm Region. Geo-structural analysis, phyto-indication, and biolocationwere used. Prior to this, forest ecosystems were studied by classical methods, in which it was found that the combinedinfluence of the density of microcenosis and the tree genotype determines the size of trees by only 40 %. It follows that 60%of the factors that determine the size of trees in different phytocenotic and soil conditions remain unknown. Therefore,we then began to study small geoactive zones (MGA-zones) with the hypothesis that they are related to the “small ringstructures of loose deposits of the earth’s crust” by Yu. I. Fivensky. Favorable MGA zones with a size of 1.0-3.0 m are foundwith a frequency of 220-250 pcs./ha and the pine tree is preserved 39 times better, increases the trunk volume by 46 %,forms 200-year-old forests, and its large trees are their indicators. Networks of them can be used as an energy frameworkand, for example, in a forest nursery, their energy in the conditions of cold spring increased the germination of spruceseeds by 7 times. Apparently, the forest species evolved using the energies of these zones; in any case, all the tree species westudied significantly increased their longevity and size. It shows promising sites with structures of Yu. I. Fivensky, whererings of hellebore (Verátrum lobeliánum Bernh.), fern (Dryopteris filix mas L.), and the highest trees of Siberian spruce(Picea obovate Leded) were previously discovered for the first time.) and Siberian cedar pine (Pinus sibirica Du Tour).

Authors: Speranskaya N. Yu. , Lyashchenko A. D. , Zembrovskaya T. A.
Published: October 2021

Many members of the Orhidaceae family are rare plants. One of the effective ways to preserve these speciesis to include them in the Red Book and give them a certain status of rarity. Neottianthe cucullata has a wide species rangein the Russian Federation. This species is found in almost all regions located in the temperate zone. Neottianthe cucullatais included in the Red Book of the Russian Federation and, accordingly, is protected in 48 regions of Russia. The speciesgrows mainly in coniferous and mixed forests, so the main threat to it is the increasing rate of logging. Disturbance of soilcover and changes in environmental conditions are limiting factors. However, the analysis showed that the state of populations in different regions is very different. In the European part, where the pressure on forest resources is very high,Neottianthe cucullata has a status ranging from «probably extinct» to «very rare». In some cases, reliable information is notavailable. On the territory of Siberia, the species belongs to category 3 – rare. On the territory of the Republic of Buryatia, it belongs to category 7 – out of danger. Most often, the populations of Neottianthe cucullata are well studied and protected in nature reserves and sanctuaries. In a number of regions, there is no information on the state of local populations.

Published: October 2021

. The article presents the results of the conservation of woody and semi-woody species under introductionconditions in the collection “Rare and endangered plant species of Siberia” of the Central Siberian Botanical Garden (Novosibirsk). This collection was founded in 1965 years. The analysis of the fund of this collection is carried out. For a longtime (more than 10 years), 22 woody and semi-woody species from 14 families from 8 regions of Siberia are grown in thecollection. Four species are endemic: Sedum populifolium Pallas, Cotoneaster lucidus Schlecht., Sibiraea altaiensis (Laxm.)Schneider and Tilia sibirica Fisher ex Bayer. Most of the species are represented in the collection by small populations. Thisis due to the problems of reproduction of species in the conditions of culture, for many of which methods of vegetative andseed reproduction have not been developed. The traditional method of reproduction used for herbaceous plants – laboratory-greenhouse-soil. This method is often ineffective for woody species due to the long pregenerative period and low biological longevity of seeds. In the introduction, microecological conditions are selected for each species, since they belongto different ecological groups. Among the introduced species there are 13 mesophytes, 8 xerophytes, 1 xeromesophyte. Thearticle presents literary and original information about the methods of reproduction of cultivated species.

COMPARATIVE ANALYSIS OF SPATIAL STRESS IN THE JOINT ZONE OF TOWER PIER UNDER DIFFERENT SYSTEMS OF CABLE-STAYED BRIDGE
Authors: Liu Long , Bi Yingying
Published: October 2021

To explore the stress of the tower-beam-pier joint zone of a cable-stayed bridge under different systems, the submodel method in the finite element software ABAQUS was used to establish the local model of the tower-beam-pier joint zone of the bridge. At the same time, Midas/Civil was used to establish the rod system finite element model of the whole bridge. The correctness of the local model was verified by comparing the results of the finite element model and the local model. Then, by changing the combination mode of tower beam pier, the stress comparison analysis of the joint zone of the tower-beam-pier under different systems was carried out. The results showed the stress distribution of the semi-floating system was more reasonable than that of the rigid frame system and the consolidation system. In the use of the three different systems, there was concentrated tensile stress at the chamfer of the web and the bottom plate, where the steel bars should be added. In the rigid frame system, the deflection of the main beam under the load was the smallest, and the maximum displacement occurred at the boundary section, with the value of only 2.668mm.

Drying Kinetics, Rehydration Behavior and Morphological Properties of Pre-blanched Thai Basil Leaves
Authors: Ma Nhu Bich , Ha Le Thanh Thi , Le Ngoc Lieu
Published: October 2021

Drying characteristics of Thai basil (Ocimum basilicum var. thyrsiflorum) leaves during hot-air drying process at different air temperatures with and without blanching pre-treatment were in-depth investigated. The increase in drying rate and decrease in drying time were observed at elevated temperatures. Blanching further reduced the drying time by approximately 19–45%, indicating to potentially reduce energy consumption of drying. The Midilli et al’s model demonstrated the best fitting to describe the process. The effective moisture diffusivity was computed as 0.21–1.55×10–10 m2s–1. The lower activation energy of water removal during drying for blanched leaves indicated that blanching had more energy efficiency at lower temperatures. Blanching also improved rehydration capacity of dried leaves. Microstructural analysis revealed that blanching caused the collapse of the cellular structure and shrinkage and hence reduced the resistance of moisture removal leading to a higher drying rate. The findings in this work prove that blanching can be a potential approach to save consumed energy, reduce drying time, and hence potentially preserve beneficial properties of bioactive compounds in agricultural plants.

Authors: Harikrishnan S. , Kumar Kamlesh , Venkateswara Rao V. , Misra Ajay
Published: October 2021

This paper discusses the experimental determination of explosive shock attenuation parameters of four different polymers viz., Teflon, Phenol formaldehyde, Polyethylene foam and Polypropylene foam. These polymers are candidate materials for waveshapers in shaped charge warheads. Cylindrical specimens of the polymer materials were subjected to explosive shock loading by the detonation of RDX:Wax (95:5). Shock arrival time was measured using piezo-wafers positioned at known spatial intervals in the specimens. Initial shock velocity, stabilised shock velocity and attenuation constant were determined. These parameters are essential for the design of waveshapers. Foams have better shock attenuating properties compared to solids due to their cellular structure. Polypropylene foam has the highest shock attenuating characteristic among the four materials studied.

Published: October 2021

On the battlefield of today, it has become an important requirement to hit moving or fixed targets by using tank or artillery ammunition with high precision. However, while there are many articles on guiding tactical missiles, it cannot found sufficient scientific study for guiding tank ammunition in the related literature. In this study, the laser BR-guidance method is offered to the classic tank ammunition with a diameter of 155 mm in order to give the tank a precision strike capacity, as different from the literature. First of all, an ammunition model is created with coefficients of the mass, inertia, and surface area and friction. In addition, an autopilot dynamic is modeled for the pitch and roll axes of the ammunition. Also, the atmosphere model and environmental factors are added to the model. In order to control this nonlinear model, a lead-compensator and a PD-controller are designed. In order for the results to be transferred to a real application, the accelerations obtained must basically be produced by the electric motors that will drive the control surfaces to be designed. At the end of the study, it is seen that both controllers can produce lateral accelerations within limits without reaching high saturation.

Thermal treatments affected to quality attributes of Solanum procumbens Lour.
Authors: Minh Nguyen Phuoc
Published: October 2021

Solanum procumbens Lour. plant has been distributed in many places of Vietnam and tropical regions. Its extract includes numerous therapeutic properties in pharmacopeia. This research evaluates the possibility of dried herbal tea production from this valuable phytochemical source. Different variables of vapor steaming, convective drying, roasting are verified to monitor the degradation of total phenolic content, total flavonoid content, diphenylpicrylhydrazyl (DPPH) free radical scavenging, ferric reducing antioxidant power (FRAP) and overall acceptance in Solanum procumbens. Results show that Solanum procumbens should be blanched by steaming within 45 s as primary treatment, dehydrated at 45/7.0 ºC/hrs, roasted at 150/20 ºC/min to preserve the most antioxidant constituents with total phenolic content, total flavonoid content, half inhibitory concentration (IC50) of DPPH, FRAP as well as the highest organoleptic value. High retention of total phenolic content, total flavonoid content, antioxidant power as well as high sensory score of the dried Solanum procumbens herbal tea plays an important decision in consumer preference and acceptance. All these processing steps can be performed in simple handling with universal available equipments like steaming oven, convective drier and roasting oven. Findings in this study will be useful data for house-hold scale production.
Nowa Muzyka i przyjemność w serii utworów audiowizualnych ASMR Neo Hülckera
Authors: Pasiecznik Monika
Published: October 2021

New Music developed in the twentieth century under the influence of Theodor W. Adorno’s philosophy. Its sense, according to the philosopher, lies in social criticism, which the composer accomplishes through radical artistic innovation, and the distance from the audience’s expectations. The sensual pleasure of sound reception is not included in the concept of New Music, which preferably should not appeal to anybody, as it “took on the shoulders darkness of the world and all its guilt, and sees its only happiness in knowing misery” (Adorno).

In the ASMR series, the German composer Neo Hülcker breaks this paradigm of perception and proposes a radically different interpretationof New Music.ASMR, or Autonomous Sensory Meridian Response, is a sensation of pleasant tingle, caused by subtle acoustic-haptic phenomena, such as amplified murmurs, whispers, touching objects and materials. Millions of people around the world are watching ASMR videos on YouTube that let them relax nicely.In such video compositions as ASMR Tutorial: How to Play “Pression” by Helmut Lachenmann, ASMR Tutorial: How to Play Mark Andreor ASMR Unwrapping the Piano & iv 11a, and Peter Ablinger: weiss/ weisslich 3 – [super soft ASMR] Neo Hülcker investigates the similarityof sound material of illustrative pieces of New Music and ASMR, raising the question of whether New Music can make someone feeltingly. Presenting in the context of ASMR works by Helmut Lachenmann, Mark Andre and Peter Ablinger, Hülcker explores the hiddenpotential contained in the most radical aesthetics of New Music, namely the suppressed carnal pleasure. The article is an attempt to show the ways how Neo Hülcker redefines the concept of New Music, entering in it the sensual experience of sound.
Izotopie w praktyce analizy dzieła muzycznego – na przykładzie "Arabesque" Zygmunta Krauzego
Authors: Skupin Renata
Published: October 2021

The aim of the paper is to reconsider the question of usefulness of the category of isotopy in semiotic analysis of a musical composition, on the example of Zygmunt Krauze’s Arabesque (1983) for prepared piano and instrumental ensemble. Adopting a suggestion by Nicolas Meeùs, the author undertakes an attempt to transpose Rastier’s differentiation between semantic isotopy and isotopy of the plane of expression (isotopie de l’expression) into analysis of music. Following Michel Arrivé, she presents a model example of isotopic relations in the plane of expression (signifiant) from the novel Les jours et les nuits (Days and Nights) by Alfred Jarry, and finds that isotopy of the plane of expression is for linguistic semioticians an alternative to semantic isotopy in providing cohesiveness in the layer of signs that construct meaning. She then discusses the extent of application of isotopy in music semiotics and draws attention to the semantic capacity of this category in Eero Tarasti’s theory and interpretive practice, where it undergoes metaphorisation and a kind of universalisation. She also refers to the proposal of Jean-Pierre Bartoli to use isotopy in analysing Orientalistic exoticism, which constitutes an example of a return to the level of the simplest constitutive units and the condition of their iteration, i.e., to the structuralistic-semiotic conceptions of isotopy in the approach of Greimas. Moving on to an analysis of Krauze’s composition, the author puts forward the view that Rastier’s categories of isotopy of the plane of expression as „conditions of grammaticality” (conditions de grammaticalité) of an utterance can only apply to specific cases of compositional techniques which are utterances in systemic „musical languages”, and this condition is not met in the case of the work analysed. The argumentation presented in the article is based on an analysis of particular features of the organisation of the sound material, the texture and syntax of Arabesque, as well as references to the composer’s claim to have been inspired by the mystical paintings of Władysław Strzemiński and the oriental connotations of arabesqueness in music. In seeking the musical meaning of Krauze’s Arabesque the author focuses on identifying its intentio operis.
The Moving Plane Method for Doubly Singular Elliptic Equations Involving a First-Order Term
Authors: Esposito Francesco , Sciunzi Berardino
Published: October 2021

In this paper we deal with positive singular solutions to semilinear elliptic problems involving a first-order term and a singular nonlinearity. Exploiting a fine adaptation of the well-known moving plane method of Alexandrov–Serrin and a careful choice of the cutoff functions, we deduce symmetry and monotonicity properties of the solutions.
Improving mechanical and water vapor barrier properties of the parylene C film by UV-curable polyurethane acrylate coating
Authors: Jing Zekun , Guo Yakun , Ren Meng , Zhao Xingtao , Shao Hong , Zhou Yuanlin , Shuai Maobing
Published: October 2021

Parylene C (PC) films have been widely used in many fields, such as metal anti-corrosion, electronic packaging, etc. However, the relatively poor mechanical properties and the deteriorated water barrier performance due to the easy fracture under external stress have restricted their application. It is a relatively simple and good method to maintain the water vapor barrier and enhance the mechanical properties of PC film by covering a flexible coating on its surface. In this work, a new polyurethane acrylate (PUA) coating was prepared and coated on the PC film by ultraviolet curing technology to form the PC/PUA composite film. The results showed that the PUA coatings could improve the water vapor barrier and mechanical properties of the PC film simultaneously. The water vapor transmittance rate was reduced from 1.1791 g·(m−2·day−1) of the original PC film to 0.5636 g·(m−2·day−1) of the PC/PUA composite film. The elongation at break and the impact energy were increased to 48.36% and 41.67%, respectively, which would widen the application of PC films in the fields of flexible electronics or smart wear.

Authors: Elia Mattia
Published: October 2021

The report seeks to outline the issues the lecturers of the International Conference Held at the University of Turin on the 21st and 22nd June 2021 touched upon. The backbone of the Conference was the rise of Urban Commons describing all the different aspects it involves: the urban voids suitable to host urban commons, the participatory models shaping the governance of commoning, the consequences such phenomenon may imply, and the technological and legal infrastructure may flank and support the development of urban commoning. All this explored by referring to concrete case studies and day-to-day experiences.

Objectives

Congenital hyperinsulinism (CHI) is a group of rare genetic disorders characterized by insulin overproduction. CHI causes life-threatening hypoglycemia in neonates and infants. Bloom syndrome is a rare autosomal recessive disorder caused by mutations in the BLM gene resulting in genetic instability and an elevated rate of spontaneous sister chromatid exchanges. It leads to insulin resistance, early-onset diabetes, dyslipidemia, growth delay, immune deficiency and cancer predisposition. Recent studies demonstrate that the BLM gene is highly expressed in pancreatic islet cells and its mutations can alter the expression of other genes which are associated with apoptosis control and cell proliferation.

Case presentation

A 5-month-old female patient from consanguineous parents presented with drug-resistant CHI and dysmorphic features. Genetic testing revealed a homozygous mutation in the KCNJ11 gene and an additional homozygous mutation in the BLM gene. While 18F-DOPA PET scan images were consistent with a focal CHI form and intraoperative frozen‐section histopathology was consistent with diffuse CHI form, postoperative histopathological examination revealed features of an atypical form.

Conclusions

In our case, the patient carries two distinct diseases with opposite metabolic phenotypes.
