BACKGROUND

Digital lifestyle interventions can help cancer survivors better manage their disease through improved lifestyle choices.

OBJECTIVE

Our aim was to test the feasibility of a digital therapeutic (DTx) program for cancer patients, as measured by engagement, retention, and acceptability. We additionally explored the effects of the program on cancer-related quality of life.

METHODS

A four-week-long, single-arm trial was conducted in Iceland where the DTx was delivered through a smartphone app. The intervention consisted of completing daily missions (e.g., food logging, activity tracking, surveys) and receiving educational content about mindfulness, sleep, stress, and nutrition. Usage information such as engagement, retention, and step goal attainment, as well as patient-reported outcomes about energy, stress and quality of sleep were collected throughout the study. Cancer-specific quality of life using the EORTC QLQ-C30 questionnaire, as well as cardiovascular fitness and body composition were measured at baseline and follow-up.

RESULTS

Thirty cancer patients in active treatment were enrolled and 29 registered in the program (79% female, with mean age of 52.6 years, 62% with breast cancer). All 29 participants were active at least three out of four weeks, and 28 (97%) completed the pre- and post- program questionnaires. 72% were highly engaged, the median number of weekly active days were 6.8 (IQR: 5.8, 6.8), and mean daily mission interactions were 7.7 (SD = 1.9). On week one, all 29 participants used the step counter, and 72% reached their step goals; most of these individuals (n = 27) were still using the step counter on week four, with 70% reaching their step goals. The DTx had high acceptability, as 89% of participants said they were likely to recommend it, and 82% said the program helped them deal with the disease.
Quality of life (QoL) assessment showed that global health status, functioning and symptom burden remained stable from baseline to follow-up. The largest improvement was observed in pain scores, which decreased from 31 (SD = 20.1) to 22.6 (SD = 23.2) (P= .16).

CONCLUSIONS

The high retention, engagement and acceptability found in this study demonstrate that a multidisciplinary DTx is feasible for cancer patients. A longer, full-scale randomized controlled trial (RCT) is currently being planned to evaluate the efficacy of the intervention.
Numerical Simulation for One-Dimensional (1D) Wave Propagation by Solving the Shallow Water Equations using the Preissmann Implicit Scheme
Authors: Lidyana Prilla , Ginting Bobby Minola , Yudianto Doddi
Published: May 2022

This research simulated one-dimensional wave propagation by solving the shallow water equations using the Preissman implicit numerical scheme due to its ability to maintain simplicity and stability at a larger time step value. This numerical model was fundamentally developed to satisfy the shallow water condition, where the water depth or horizontal-length scale is much smaller than the free-surface disturbance wavelength or vertical-length scale, and to comprehensively test the accuracy of the model. Consequently, three different types of waves were considered and these include (1) tidal, (2) roll, and (3) solitary. In the first case, the model was proven to be robust and accurate due to its relatively-small errors for both water-surface elevation and velocity indicating that the Preismann scheme is suitable for longwave simulations. In the second case, it was fairly accurate in capturing the periodic permanent roll waves despite showing a higher water-surface elevation than the one observed and this discrepancy is due to the neglect of the turbulent Reynold stress in the model. Meanwhile, the last case showed remarkable discrepancies in the water-surface elevation because the dispersion effect is quite significant during the wave propagation. This indicates that the Preismann scheme underestimated the wave crest along with time when the dispersion term was neglected. All simulations were performed using the tridiagonal matrix algorithm, thereby eliminating the need for iterations for the solution of the Preismann scheme. The findings of this study are beneficial to the next generation of the Preissmann-scheme models which can be designed to include turbulence and dispersion terms.

Accelerated Sulphate Attack Study on Cement – Metakaolin – Flyash Concretes
Authors: Tiwari Abhay , Kumar Awadhesh
Published: May 2022

Durability is that property of concrete which plays the prime role in governing the lifespan and serviceability of a structure with regard to its intended usage. Environmental conditions of the surroundings are the main criteria which decide the longevity and performance of concrete. For understanding the durability of concrete structures, analysis of the impact of chemical attacks may be crucial. As sulphate attacks are predominant chemical attacks on concrete structures, their study can interpret it when they are subjected to deterioration followed by damage. In this study, the effectiveness of ternary blends of OPC with metokaolin (MK) and flyash (FA) in sulphate resistance of concrete exposed to accelerated effect (i.e. by wetting and drying cycles) in 10% solution of sodium sulphate has been investigated. To assess the level of sulfate attack, the changes in strengths of concrete specimens and their weight change were measured after certain numbers of deterioration cycles. Cubes, prisms and cylinders of concrete were tested for compressive, flexural and splitting tensile strengths respectively whereas the weight changes (in percent) were measured for all the specimens. Combination of OPC with MK and FA has proved its effectiveness in improving the resistance against sulphate attack.
Morphological, structural and electrochemical properties of the LaNi4Fe compound elaborated by mechanical alloying
Authors: Moussa M. Ben , Hakamy A. , Abdellaoui M.
Published: May 2022

In this paper, we have studied the morphologic, the structural and the electrochemical properties of the LaNi4Fe compound elaborated by mechanical alloying (MA) for two durations 5 and 10 h. These properties are determined by various methods, such as XRD, SEM and galvanostatic cycling. The results show that the LaNi4Fe compound crystallizes in the hexagonal CaCu5 type structure for the two alloying durations 5 and 10 h. The particles obtained by mechanical alloying are in the order of 6 to 7 nm. The chemical microanalysis by EDX shows that the nominal and actual compositions are very close for the two grinding times. The maximum discharge capacity, of 180 and 200 mAh / g respectively for 5h and 10 h, is obtained from the first two cycles, which shows that the activation of nano compounds is easier than that obtained for bulk material obtained by melting since the reaction surface is larger. A decrease in capacity is observed after about thirty cycles: A loss of around 15% of maximum capacity is observed.

Published: May 2022

Korobchyne-kurhan stone age site in the Velyka Vys River basin, in Central Ukraine is investigated for raw material and contacts. The surrounding geography and the site are presented. The extensive search of outcrops around the monument resulted in nearer outcrops than was previously expected. Scientific investigations on 15 artefacts from Korobchyne-kurhan using non-destructive microfacies analysis allows us to have a first insight in the raw materials used by the prehistoric people and to give a detailed description from the encountered silicite varieties. Interestingly artefacts, composed of two different materials were found. That work confirms the use of the local materials as well as of some other material of yet unknown origin. The exogenous material is as well testified in younger sites in the Southern Buh River valley farther to the west.

Authors: Arriola-Pizano José Gabriel , Aldeco-Ramírez Javier , Salas-de León David Alberto , Pagano Marc , Mendoza-Vargas Leonor
Published: May 2022

We analyzed the abundance, diversity, and distribution of euphausiids and their relationship with hydrodynamic processes from February 2011 to October 2012 in the Campeche Canyon in the southern Gulf of Mexico. Sampling was conducted at 55 oceanographic stations and zooplankton were captured using horizontal trawls. Environmentalvariables (temperature, salinity, and oxygen) and phytoplankton fluorescence were recorded at different depths. Twenty-four species of euphausiids representing the genera Euphausia, Nematobrachion, Nematoscelis, Stylocheiron, and Thysanopoda were identified. Stylocheiron carinatum was abundant in February and October, with the furcilia stage always the dominant one. Differences were observed among the 4 zones identified based on the bathymetric criteria; zone III (axis and head of the canyon) presented the highest diversity of euphausiids between 100 and 200 mwith 2.14 bits Ind-1 in February and 1.99 bits Ind-1 in October. The spatial-temporal distribution of euphausiids was heterogeneous in water bodies with temperatures between 15 and 22 °C and low dissolved oxygen concentrations, which were distributed outside the maximum concentrations of chlorophyll-a (2,127 mg m-3) and had an affinity for the frontal regions between cyclonic and anticyclonic eddies.

The Neotropical otter Lontra longicaudis is one of the least studied mammals of the Yucatán Peninsula and its presence in some water bodies of this region is questionable. Laguna Bacalar is the largest freshwater body located in the Yucatán Peninsula and faces several conservation problems due to its high potential for tourism development. We confirmed the presence of L. longicaudis in Laguna Bacalar by conducting interviews with residents, and the search for direct (sightings) and indirect (e.g., footprints) evidence of the species in 2013. We also include recent direct and indirect evidence (2019-2020). We classified the records into levels of certainty, according to the type of evidence (photographs, videos). We obtained 9 records of Neotropical otter through interviews (level 3), 3 sightings and 4 footprints (level 1), and 4 sightings (3 of these with level 2 and 1 with level 3 of certainty). It is necessary to increase the research effort to determine the conservation status and distribution of the Neotropical otter in the lagoon. We recommend making efforts in terms of socialization and education to facilitate the conservation of the Neotropical otters and their habitat in Laguna Bacalar.

Published: May 2022

En México, uno de los principales mecanismos para preservar la biodiversidad son las áreas naturales protegidas (ANP). No obstante, para poder implementar acciones eficaces de conservación, es indispensable saber qué especies habitan en las ANP (gubernamentales y privadas), y en qué categoría de riesgo se encuentran. Utilizando las áreas de distribución y categorización de la UICN, la NOM-059 y la serie VI de vegetación y uso de suelo, planteamos una priorización para la conservación de los anfibios de México. Proponemos 5 categorías para que las especies puedan ser reevaluadas constantemente determinando su prioridad: 1) especies que no están en ninguna ANP y que tienen 100% del área modificada; 2) especies que no están en ninguna ANP, y que tienen entre 70 y 99% del área modificada; 3) especies microendémicas que no están en ninguna ANP, sin importar la cantidad de área modificada; 4) especies microendémicas que están en una ANP y que entre tienen entre 70 y 99% de área modificada; y finalmente, 5) especies que no están en ninguna ANP, sin importar la cantidad de área modificada.

Published: May 2022

Las macroalgas dependen de sustratos específicos para su crecimiento y propagación. Esta relación es importante para comprender el funcionamiento de los arrecifes de coral. En México, sin embargo, los estudios sobre este tema son escasos. Así, en el presente estudio se determinó la diversidad de especies de macroalgas en el Parque Nacional Arrecifes de Xcalak (PNAX), en relación con el sustrato que colonizan. En julio del 2012, se seleccionaron 10 sitios de muestreo en 4 zonas del PNAX: canal de Zaragoza (C), laguna arrecifal 1 (LA1), laguna arrecifal 2 (LA2), y arrecife frontal (AF). Con ayuda de transectos y cuadrantes se recolectaron manualmente especímenes de 61 taxones de macroalgas (entre ellos un morfotipo), principalmente rodofitas, sobre 3 sustratos abióticos y 18 bióticos. De estos taxones, 17 especies constituyeron nuevos registros para el PNAX y 1 para la costa de Quintana Roo. La diversidad fue mayor en LA (3.89), seguido de AF (3.71), observando especies comunes entre ambas zonas. Las familias Halimedaceae, Udoteaceae y Anadyomenaceae se observaron sobre sustrato abiótico, mientras que las familias Halimedaceae y Dictyotaceae constituyeron sustrato para otras rodofitas. El número de macroalgas registrado en el PNAX representa 10.4% del total registrado para la costa de Quintana Roo.
preludio francés de la representación: la diputación americana en la asamblea de Bayona en 1808
Authors: Lovera Lorenzo Alicia
Published: May 2022

La cuestión de la representación política fue uno de los problemas abiertos en España y en América tras la crisis política de la Monarquía hispánica en 1808 y fue también una preocupación en los órganos de gobierno que intentaron mandar, entre ellos el pretendido gobierno de Bonaparte. En el afán de ganar el apoyo de los españoles, el corso concibió el proyecto de dar una constitución con el que prometía reformar el sistema español y dar representación a los territorios de ultramar, hecho por demás inédito en la Monarquía. Bonaparte convocó la reunión de una Asamblea en Bayona, en la que participaría también una diputación americana, la cual planteó una serie de propuestas para transformar su lugar en la Monarquía. Este artículo analiza las propuestas americanas de cara a la posterior concesión de representación que hizo la Junta Central en 1809.

Teatro, o Luto e a Cidade: um estudo acerca do espaço não convencional na perspectiva da estética pós-dramática
Authors: De Paula de Lemos Neris Elisabete , Berselli Marcia
Published: May 2022

Quanto de vazio, luto e perda há em cada esquina, rua e viela de uma cidade? O espaço público carrega consigo, silenciosamente, as cicatrizes de seus(suas) transeuntes, afetados(as) pela negligência a seus sentimentos de dor. O presente artigo busca pensar a relação entre aspectos que caracterizam o teatro pós-dramático e a temática do luto pela morte de uma criança a partir da análise de uma encenação desenvolvida e compartilhada em espaços não convencionais de teatro. Ao realizarmos a referida montagem em espaços da cidade, nos deparamos com uma poética cênica que dialoga diretamente com o imaginário das pessoas espectadoras, destacando o paradoxo do teatro que carrega uma dimensão tanto coletiva quanto individual, assim como a relação com os espaços públicos e com a própria temática da encenação aqui analisada, que remete aos sentimentos de vazio que carregamos em nosso ser.

Cinnamon and its extracts have been used herbal remedies including
reducing insulin resistance and diabetic complications. T2DM is a
rapidly growing health concern around the
world[[1]](#ref-0001). While many drugs are now available for
T2DM treatment, side effects and costs can be considerable, and there is
increasing interest in natural products for managing chronic health
conditions[2]. Cinnamon may decrease the expression of genes
associated with type 2 diabetes (T2DM) risk. The purpose of this study
was to evaluate the effects of cinnamon water extract (CWE) and
metformin on T2DM-related gene expression. The HepG2 human hepatoma cell
line is widely used in drug metabolism and hepatotoxicity studies. HepG2
cells were treated with different concentrations of metformin or CWE for
24 or 48 h. Cell viability was assessed by MTT assay, and glucose uptake
was compared between untreated and CWE- or metformin-treated cells under
high-glucose conditions. Finally, total RNA was extracted and analyzed
by RNA sequencing (RNA-Seq), and bioinformatics analysis was performed
to compare the transcriptional effects of CWE and metformin. We found
that cell viability was higher in cells treated with CWE than in
metformin-treated cells, demonstrating that the cinnamon extract was not
toxic at the tested doses. CWE significantly increased glucose uptake in
HepG2 cells to the same degree as metformin (1.4-fold). RNA-Seq data
revealed that CWE and metformin both induced significant changes (1.3-
to 1.4-fold increases) in glucose uptake gene expression compared with
untreated controls, but that transcriptional differences between CWE and
metformin conditions were not significant. The effects of 0.125 mg mL
CWE on gene expression were comparable to those
seen with 1.5 mg mL (9.5 mM) metformin. We found
that gene expression at 0.125 mg mL-1 CWE was comparable to 1.5 mg mL-1
(9.5 mM) metformin. Our results reveal that CWE’s effects on cell
viability, glucose uptake, and gene expression in HepG2 cells are
comparable to those of the widely used antidiabetic drug metformin,
suggesting that CWE may be an effective dietary supplement for
mitigating T2DM-related metabolic dysfunction.

The modern labor market places quite high demands on graduates of agrarian universities. The competition in qualifications requires practical skills that can be demonstrated in the agrarian sector of the economy. Increased attention to the practical component of the educational process is required. The system of practice-oriented education includes various forms of interaction: early profiling of future students, their practical training, and research work. Successful training of highly skilled modern agrarians and their adaptation to the modern requirements of the labor market and the needs of future employers is only possible in the best farms constructed based on the examples of modern innovative technologies and techniques. Therefore, it is critical to further develop educational and experimental farms, experimental stations, and experimental sites and productions based on agricultural universities.
The influence of educational factors on attracting investors

Published: May 2022

A significant disadvantage of the current system of forming programs for the socio-economic development of municipalities is the orientation towards short- and medium-term goals, the lack of complexity in them, as well as uncertainty in the sources of financing of program activities. The topic of assessing the investment attractiveness of municipalities is relevant both at the national level and at the municipal level. The relevance of the research topic is determined by the fact that the problem of attracting investments is constantly in the spotlight in modern market conditions. This happens because investments are becoming an important resource for the development of the municipality. Due to the limited possibilities of federal investment support, municipalities need to focus on creating the investment attractiveness of their territory and, as a result, increasing investment activity.

Investor Disagreement, Disclosure Processing Costs, and Trading Volume Evidence from Social Media
Authors: Booker Adam , Curtis Asher , Richardson Vernon J.
Published: May 2022

We use posts on the investor-focused StockTwits social media network to generate new insights regarding investor disagreement, disclosure processing costs, and trading volume around earnings announcements. Using social media-based measures of disagreement, we find that both preannouncement disagreement and increases in disagreement around an earnings announcement are positively associated with trading volume. Drawing upon the disclosure processing costs literature, we provide evidence that the effects of disagreement increase when disclosure processing costs are lower. Our social media measures of disagreement remain significant after including traditional analyst earnings estimate measures of disagreement in the model. Our study provides new evidence on the importance of disclosure processing costs and is consistent with lower disclosure processing costs amplifying both the resolution of preannouncement disagreement and new disagreement about earnings information.

Decision Facilitating Information and Induced Volatility: A Study of Tradeoffs in Accounting Disclosure
Authors: Kanodia Chandra , Venugopalan Raghu
Published: May 2022

Corporate managers often express concern about accounting-induced volatility in financial statements. Accounting regulators, however, argue that the volatility in financial statements merely increases transparency by shining a light on risks that are inherent to the firm’s business. We show that in many situations managerial concerns about volatility are justified because the information that is being provided actually magnifies rather than merely reflects the volatility in a firm’s fundamentals. Corporate managers anticipate the magnified volatility and take preemptive actions to decrease the firm’s exposure to the accounting treatment that induces volatility. These actions may not be in the best interests of external stakeholders, making disclosure costly, while at the same time improving the decisions of external stakeholders. We develop and study the resultant tradeoff that accounting regulators should consider in setting accounting standards.

To evaluate this effectiveness, a study was conducted during December, 2019−April, 2020 (rabi) at Central Farm of Odisha University of Agriculture and Technology, Bhubaneswar- 751003, Odisha aimed at evaluating the efficiency of seven isolated rhizobial strains of pigeon pea viz. BRP-2, BRP-4, BRP-8, BRP-20, BRP-28, BRP-56 and a local strain CHRS-7 in a randomized block design with four replications. The pigeon pea cv PRG-176 was used for study. The results revealed that seed inoculation with different Rhizobium strains enhanced the plant height (41.84–90.09 cm), relative growth rate (0.410−0.898 mm day-1), nodular characteristics, nodular nitrogen (3.11 to 4.11%), pod and seed characteristics in pigeon pea. In addition to that the potentiality of pigeon pea producing only 408 kg seed ha-1 without any seed inoculation could be enhanced to produce 888 kg seed ha-1 by seed inoculation in a coastal agroecosystem. The findings also revealed a better uptake of nutrients by the crop in Rhizobium inoculated practices that performed in the order Control <BRP-20<BRP-8<BRP-4<BRP-56<BRP-28<BRP-2<CHRS-7. The performance of local isolated rhizobial strain (CHRS-7) was better over other strains and it gives cardinal importance for the enhancement of pigeon pea growth, productivity and economics in a coastal acidic Alfisols.

Thirty five chilli genotypes were evaluated in a randomized block design at College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana State Horticultural University, Hyderabad, Telangana state, India during Kharif, 2019 for seven months and at National Bureau of Plant Genetic Resources, Regional station, Rajendranagar, Hyderabad during Rabi 2019-20 for seven months to estimate genetic variability, heritability, genetic advance and genetic advance as % of mean of seventeen yield and yield related traits. For all the traits studied, the magnitude of PCV was higher than corresponding GCV. High Phenotypic coefficient of variation and genotypic coefficient of variation estimates were recorded for plant height, plant spread, fruit length, fruit diameter, number of fruits plant-1, fruit weight, fruit yield plant-1, fruit yield plot-1, ascorbic acid, capsaicin content and capsanthin content indicating the existence of wider genetic variability for these traits in the genotypes studied. High heritability was recorded for the traits Days to first flowering, Fruit length, Fruit diameter, No. of fruits plant-1, Fruit weight, Fruit yield plant-1, Fruit yield plot-1, Ascorbic acid, Chlorophyll content, Capsaicin content and Capsanthin content. High heritability coupled with high genetic advance as % mean indicates existence of additive gene action which was observed in fruit length, fruit diameter, number of fruits plant-1, fruit weight, fruit yield plant-1, fruit yield plot-1, ascorbic acid, chlorophyll content, capsaicin content and capsanthin content. Hence these traits can be improved by direct selection.

Conservation agriculture (CA) involving minimum mechanical soil disturbance, permanent soil cover with crop residue mulch and diversified crop rotation, plays a crucial role in sustainable crop production. A field experiment was conducted at ICAR-Indian Agricultural Research Institute, New Delhi during rabi seasons (November–April) of 2018–19 and 2019–20 in wheat involving maize-wheat-mungbean system to assess the effects of CA on crop productivity, nutrient uptake and profitability. Results showed that CA-based practices with residue retention resulted in higher yield as well as economic benefits when compared to conventional tillage (CT). Wheat yield parameters in CA were greater than in CT. The CA-based practices improved wheat grain and straw yield to the tune of 7.2–27.1% and 5.7–20.6%, respectively compared to CT practice. The CA-based practices with residue retention with 100% N registered 9.7% higher cost of cultivation, but resulted in 24.3–35.1% higher net returns than CT. Among CA-based practices, the plots under permanent broad bed with residue with 100% N (PBB+R+100N) resulted in ~27% higher wheat grain yield compared to CT. The PBB+R+100N plots also had considerably greater nutrient uptake and net returns than CT plots. The CA practice involving PBB+R+100N was found to be more productive, remunerative and could potentially boost up the wheat productivity and profitability under maize-wheat-mungbean system in north-western Indo-Gangetic Plains of India.

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne virus that causes silent infections of livestock animals and severe illness in humans. Circulation of CCHFV among animals within a geographic region can be detected by the presence of antibodies to the virus. In Kosovo, human cases have occurred most frequently in the Malisheve region, but have not been seen in Vushtrri. The study was carried out in 2018 in Malisheve and Vushtrri to determine the prevalence of antibodies to CCHFV in domestic animals in Malisheve and Vushtrri, and if there is evidence that the virus is becoming more widely distributed within Kosovo. Blood samples were collected from 385 animals (285 cattle, 87 sheep and 13 goats), from 33 locations and 58 farms in total. Sera were tested using enzymelinked immunosorbent assay (ELISA) for anti-CCHFV antibodies (IgM/IgG). The seroprevalence of antibodies in Malisheve was 24.7% (59 out of 239) (CI 19.65-30.52), while in Vushtrri the seroprevalence of antibodies was 4.8% (7 out of 146) (CI 2.34-9.57). This is the first record of seropositive livestock in the Vushtrri region, suggesting that the virus is spreading in Kosovo through the movement of infected animals. Public health and veterinary state institutions should therefore start an integrated surveillance program with a concept of “One Health”, to control and prevent the spread of the virus.

The purpose of this study was to detect gastric changes in Parkinson’s disease induced by 1-methyl-4-phenyl-1.2.3.6.-tetrahydropyridine (MPTP), and to investigate the protective effect of docosahexaenoic acid (DHA) against these changes in mice. The mice were divided into 4 groups (n=10 in per group) as control, DHA, Parkinson and DHA+Parkinson groups. DHA was administered by gavage for 30 days. On the 23rd day of gavage treatment, the animals of the Parkinson and DHA+Parkinson groups were intraperitoneally injected with MPTP. Seven days after the injection of MPTP, their locomotor activity, bradykinesia and rotarod performance were measured. Tyrosine hydroxylase expression in substantia nigra and the apoptotic index, the concentrations of tumor necrosis factor-α and histamine, and the number of mast cells in the stomach were evaluated. Administration of DHA significantly prevented the reduction in motor functions (P<0.001) and nigral TH neurons (P<0.05), and apoptosis (P<0.05), and an increase in TNF-α concentration (P<0.01) in the stomach. An increase in the number of mast cells in the stomach wall was observed in PD (P<0.001). DHA prevented the increase in the number of mast cells (P<0.05) and the histamine level (P<0.01) due to PD. As a result, MPTP administration in mice caused changes in the stomach as well as impairment in motor functions, and DHA was observed to reduce these changes.

In this case, a mass located subcutaneously in the perineal subvulvar region of a six-year-old Simmental cow was examined clinically, pathomorphologically and immunohistochemically. Macroscopically, the solitary, whitishyellow-tumor mass was 19x15x6 cm in size, weighed 1610 grams, and had a lobular structure with a few small cystic formations in the section. Histopathological examination revealed that the tumor parenchyma had smooth muscle-like cells with abundant cytoplasm, pleomorphic cells with blunt-ended or cigar-shaped nuclei, anisocytosis, anisokaryosis and karyomegaly. Immunohistochemically, strong positive expression for α-SMA, vimentin, Ki67 and slight positive for desmin were found, while immulolabeling for pancytokeratin (AE1/AE3), S-100, CD31 and CD34 were negative. In conclusion, on the basis of these findings, the tumor was diagnosed as leiomyosarcoma.
