To identify prognostic factors that can be used to further improve outcome, we studied 384 patients with this genotype treated on Chinese Children’s Cancer Group acute lymphoblastic leukemia (ALL) -2015 protocol between 1 January 2015 and 31 December 2019. All patients provisionally received intensified chemotherapy in the intermediate-risk. The overall 5-year event-free survival (EFS) was 84.4% (95% confidence interval [CI], 80.6-88.3). Independent factors associated with lower 5-year EFS were male sex (80.4%, [95% CI, 74.8-86.4] vs. 88.9%, [95% CI, 84.1-93.9] in female, p = 0.033) and positive Day 46 minimal residual disease (MRD) (≥ 0.01%) (62.1%, [95% CI, 44.2-87.4] vs. 87.1%, [95% CI, 83.4-90.9] in patients with negative MRD, p < 0.001). The presence of testicular leukemia at diagnosis (n=10) was associated with particularly poorer 5-year EFS (33.3% [95% CI, 11.6-96.1] vs. 83.0% [95% CI, 77.5-88.9] in the other 192 male patients, P < 0.001) and was an independent risk factor (HR, 5.7, [95% CI, 2.2-14.5], p < 0.001). These data suggest that the presence of positive MRD after intensive remission induction and testicular leukemia at diagnosis are indications for new molecular therapeutics or immunotherapy in patients with TCF3-PBX1 ALL.

Soliton frequency combs generated in microresonators offer powerful tools for optical metrology, due to its high time-frequency resolution. Here, via exciting the intracavity Brillouin laser in a high Q monolithic fiber resonator, we generate a pair of orthogonal Kerr soliton combs, which share the same repetition (≈ 1 GHz) but different central wavelengths (≈ 10 GHz). Difference of their carrier-envelope-offset frequencies (Δfceo) is determined by the Brillouin-resonance overlap spectrally. We find that beat notes of the Δfceo is mechanically sensitive to external force, demonstrating a high sensitivity 0.3 kHz/µN, with a linear measurement range up to 7.3 mN. Leveraging the noise-filtering and lock-in heterodyne measurement, we obtain a detect limit down to 520 pN. This work reveals a novel paradigm of dual-soliton microcomb multiplexing pumped by one single laser, and combines the ultrahigh resolution dual-comb strategy and fiber sensor technology. It may open a way towards the realization of versatile and powerful microcomb based sensors with simple structure, which could be widely attractive in precision measurements such as high precision gyroscope, mechanical tracing, and material science examination.

Published: June 2022

Transposition of the great arteries (TGA) with persistent pulmonary hypertension has high preoperative mortality. We aimed to define the predictive factors for persistent pulmonary hypertension of the newborn (PPHN) in TGA by comparing patients with TGA with and without PPHN in this retrospective cohort study, which recruited patients with TGA admitted to the hospital. Demographic and clinical information, and mortality, were compared between the two groups. Eighty-four neonates were diagnosed with TGA. The majority were boys (70.2%). The median birth weight was 3,095 g (IQR 2807-3425 g). The oxygen index (OI) was 18.2 ± 11.7. Seventy patients (83.3%) presented with TGA with an intact ventricular septum (IVS). TGA with PPHN occurred in 19% (16 of 84 patients) and 15 were the TGA with IVS type. The severity of PPHN was mild to moderate in 87.5% and severe in 12.5%. Multivariate analysis, comparing the two groups, showed that a higher OI (>21) and vasoactive-inotropic score (VIS) (>50) were associated with an increased odds ratio (OR) for TGA/PPHN (OR: 45.9, 95% CI: 8.9-236.38, P=0.003; OR: 61, 95% CI: 11.4-325.8, P=0.004), respectively. The combination of TGA and PPHN has an increased risk of preoperative mortality despite successful balloon atrial septostomy for adequate mixing and optimal ventilator support. However, the development of PPHN in TGA requires aggressive PPHN treatment strategies, and can be predicted, based on our results, by a VIS >50 and OI >21.

Authors: tan weihan , zhao chaoying
Published: June 2022

In this paper, we use the Laser propagating through an optical fiber to achieve a multi-photons ultra-spatial resolution power microscopy beyond the Rayleigh diffraction limit. The uncertainty principle for multi-photons satisfies\(\frac{ \varDelta x}{n}n\varDelta {p}_{x}\ge \hslash ,\frac{\varDelta y}{n}n\varDelta {p}_{y}\ge \hslash\). The Rayleigh criterion becomes to\(0.61\lambda /n\tilde{n}\text{sin}[\theta ]\), furthermore, spatial resolving power will be improved as much as \(n\)times.

Ecosystem collapse in direct response to climate change is a critical but poorly documented phenomenon. By assessing the climate context and productivity trends in Mediterranean ecosystems worldwide, we found a large-scale, abrupt forest decline in Chile (>90% in <100 days) as response to a sustained, acute drought unprecedented in the recent history of Mediterranean-type ecosystems. These extreme conditions were projected for 2070-2090, suggesting that climate change impacts are accelerating.
Interference Patterns Within a Circular Boundary
Authors: Korula Aswan
Published: June 2022

In this paper we conduct a simple experiment wherein we create a wave within a circular container and analyse the interference patterns generated by the reflections from the boundary. In doing so we observe constructive interference in positions where our current wave theory predicts noise. This peculiar result demonstrates that in the particular situation presented here, the velocities of a wave before and after reflection from a solid boundary, are unequal.

Evidence is scant regarding the long-term humoral and cellular responses triggered by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccines in cancer patients after repeated booster doses. The possibility of T-cell exhaustion following these booster doses in this population has not yet been fully studied and remains uncertain. In this observational study, we explored the specific humoral and cellular response to S1 antigen in 36 patients with solid malignancies at baseline, and after the second and third doses of the mRNA-1273 vaccine. A dual behavior was observed: 24 (66.7%) patients showed partial specific IFN-γ response after the second dose that was further enhanced after the third dose; and 11 (30.5%) already showed an optimal response after the second dose and experienced a marked fall-off of specific IFN-γ production after the third (4 patients negativization), which might suggest T cell exhaustion due to repetitive priming to the same antigen. One (2.8%) patient had persistently negative responses after all three doses. Seroconversion occurred in all patients after the second dose. We then studied circulating exhausted CD8 + T-cells in 4 patients from each of the two response patterns, those with increase and those with decrease in cellular response after the third booster. The patients with decreased cellular response after the booster had a higher expression of CD57hiPD1hiCD8+ and CD57intPD1hiCD8+ exhausted T cells compared with those with an increased cellular response both in vivo and in vitro. Our preliminary data show that the two-dose SARS-CoV-2 vaccine regimen was beneficial in all cancer patients. An additional booster seems to be beneficial in non-optimal cancer responders to SARS-CoV-2 vaccines, in contrast to maximal responders that might develop exhaustion. Our data should be interpreted with caution given the small sample size and highlight the urgent need to validate our results in other independent and larger cohorts. Altogether, our data support the relevance of immunological functional studies to personalize preventive and treatment decisions in cancer patients.
Agricultural Pesticides used by small-scale farmers in Kenya: What are the experiences of the farmers?
Authors: Soko Jeketule Jacob
Published: June 2022

Several crops are grown in Kenya for commercial and subsistence purposes. However, pests have become a major threat to crops. To address this, farmers use different kinds of pesticides. While it is a fact that pesticides are heavily used, there is scanty literature on the nature and types of pesticides used by small-scale farmers in Kenya. Further, the extent to which the integrated pest management plan is used is not known. Therefore, this survey sought to explore major crops grown in Kenya, pests affecting them, the nature of agricultural pesticides used, and finally, the effectiveness of the agricultural pest control methods used by small-scale farmers. This was a descriptive study. 95 respondents from different counties in Kenya participated in this study. A self-administered questionnaire comprised of open-ended and close-ended questions was used in data collection. The studies revealed that farmers practiced subsistence farming. Major pests affecting crops were insects and rodents. Pests majorly affected crops while they were on the farm. Most of the agricultural pesticides used by the respondents were insecticides and rodenticides. The study established that artificial pesticides are more effective and most preferred than home-made pesticides. It recommends the adoption of integrated pest management, organic farming, and communal approaches to pest control. It further recommends training on best practices of agriculture.

Insights of Security Approach on Payment System using Blockchain
Authors: N Chitra Kiran
Published: June 2022

Blockchain-based crypto currencies have recently attracted a lot of attention due to their potential uses in a variety of fields. One of these applications is the IoT area, which can use crypto currencies for micropayments without losing their payment privacy. However, the popularity of crypto currency-based micropayments is hampered by long transaction confirmation times and relatively high costs. Payment channel networks are one of the proposed methods to overcome these issues, in which nodes create payment channels without publishing to the blockchain. As long as IoT devices can sustain their overhead, they can benefit from such payment networks. When it comes to the routing difficulty, payment channel networks have their own set of characteristics. They should, in particular, maintain a balanced network in order to continue payments for extended periods of time, which is critical for IoT devices once they are installed. In this study, This paper offer a payment channel network design that uses a common weight strategy across the network to maintain the channels balanced. For unbalanced payment scenarios, we also recommend establishing multipoint connections to nodes for each IoT device. In comparison to the minimal fee approach, the experiment results suggest that keep the network channels more evenly balanced. Furthermore, various connections from IoT devices to the nodes enhance the success ratio significantly.
Provable Secure Escrow-Free Identity-Based Signature Scheme for Smart City Environment
Authors: Kumar Mahender , Chand Satish
Published: June 2022

Smart city is a concept of digitalizing the ecosystem to solve many urban area issues such as crime reduction, transportation, waste management, and governance. However, the security and threat-related issues are still neglected. This paper presents a secure smart city framework using an identity-based signature (IBS) scheme. It is challenging to employ IBS for a smart city (a large network size) due to its key escrow nature. So, we first proposed an identity-based signature scheme that mitigates the trust on a single private key generator (PKG) by employing multiple authorities to preserve the privacy of user’s private key via threshold cryptography. The system also offloads the key protection overhead to the multiple edge gateway, making the system as efficient as the generic IBS. We demonstrate the proposed scheme is secured against the following required attacks: forgeable attack, user slander attacks, and key abusing attacks assuming the computational Diffie-Hellman problem (CDHP) in the random oracle model (ROM). Additionally, the proposed system allows the recipient to verify multiple message-signature pairs at the least cost. The performance analysis determines the optimal signature size and least computational cost compared to related systems making the proposed system suitable for implementing a secure smart city.

THE INFLUENCE OF THE CONTENT OF INNOVATIVE INDICATORS ON THE DEVELOPMENT OF THE COUNTRY’S ECONOMY (RETROSPECTIVE ANALYSIS ON THE EXAMPLE OF UKRAINE AND POLAND)
Authors: Pimonenko T.V. , Rud M.P.
Published: June 2022

The article is devoted to the analysis of innovative development of Ukraine and Poland. Management of innovation processes requires knowledge of the specifics of innovation in Ukraine and experience in the application of innovations in other countries, including Poland. Innovative development requires significant financial resources, regardless of the economy and the country. The scientific community uses a number of approaches to measure the level of innovation and innovative achievements. At the same time, there is no single and generally accepted method for assessing the level of innovative development of countries. The results of the generalization of scientific achievements on this issue showed that the most common methodology is the European Innovation Scoreboard, which is proposed by experts from the Research and Innovation Department of the European Commission. The aim of the article is to identify key areas for increasing the level of innovation development of the country based on the results of retrospective analysis of indicators of innovation development and competitiveness of Ukraine and Poland. Reports from the European Innovation Scoreboard and the Global Competitiveness Index were the starting point for the study. The results of the study showed that the main obstacle to innovative development in Ukraine, in contrast to Poland, is the significant loss of scientific and technological potential during the years of independence. It is determined that one of the strengths of the Ukrainian economy, which forms the potential to increase the level of its innovative development, is human resources. On the other hand, the efficiency of economic relations, the level of favorable environment for innovation, as well as financial and institutional support for innovation processes are the weakest dimensions of innovation. Low-rated indicators include innovators with product or process innovations, marketing and organizational innovations, and so on.
The results of a comparative analysis of the levels of innovation development of Poland and Ukraine showed the existence of large innovation gaps between the studied countries. It is established that Poland is a leader in almost all components of innovation development. In view of this, it is expedient to study the experience of Poland in ensuring the capacity building of the country's innovative development.

Published: June 2022

Outsourcing is a very effective tool in increasing the competitiveness and flexibility of the company and its successful reorganization. The article highlights the approaches of domestic and foreign scientists to the role of outsourcing in Ukraine and the world. We were convinced of the need for its evaluation and analysis. The results of the study showed the practicality of outsourcing in Ukrainian companies. The article identifies the need to change the legal framework governing this area. We identified the main problems and suggested ways to improve outsourcing. We have studied the world experience of applying this phenomenon in various fields. We analyzed the dynamics of countries around the world that use outsourcing. The purpose of this article is to study outsourcing as a tool to reduce costs and increase business profitability, its forms and types, sources of formation and development, the practice of outsourcing by different companies and development opportunities in domestic enterprises. Despite the large number of existing scientific papers on the evaluation of outsourcing as one of the links of national wealth, the issues of analysis are still incompletely worked out, and the methods used are contradictory. We conducted a comparative cost analysis using the option of outsourcing accounting and the content of its own accounting structure. The work analyzed the risks and disadvantages of using outsourcing services for Ukrainian business and developed a number of factors to improve outsourcing in Ukraine, namely: improving legislation, reviewing the tax system, holding large-scale conferences and symposia, marketing activities, restoring the education system. The analysis showed that to increase the role of outsourcing, special attention should be paid to the collection of systematization and analysis of information used in the decision to transfer business processes or functions. Qualitatively planned and mutually agreed outsourcing can significantly improve the company's performance and increase its market value.
ANALYSIS AND MODELING OF THE COUNTRIES SOCIO-ECONOMIC DEVELOPMENT WITH CONSIDERING THE LEVEL OF THEIR CYBER SECURITY

Published: June 2022

The article is devoted to the topical issue of analysis and modelling of countries socio-economic development with considering the level of their cybersecurity. This issue is due to the growing level of cybercrime, which is gaining global scale, and its consequences lead to destabilization of economic, social and political processes in society. The study was conducted based on statistics from 141 countries in 2019 using Python as the programming language. The National Cyber ​​Security Index was chosen as an indicator of the countries level to respond to various types of cyber threats. Eleven macroeconomic indices were selected as indicators of socio-economic development, which characterize GDP per capita, inflation rate, ease of doing business, unemployment rate, etc. The research methodology was conducted in six stages. The first step revealed that the data set did not contain missing values. Still, some indicators, such as inflation, unemployment, government spending on education, income excluding grants, exports of high technology, final consumption expenditures, GDP, are observed like anomalies. The main reason for this fact is the existence of a significant gap between the levels of socio-economic development of the least developed and developed countries. The correlation analysis revealed a substantial and high correlation between factors: the national cybersecurity index, overall life expectancy at birth, ease of doing business, GDP per capita, employees and vulnerable employment. They were selected for further calculations because other socio-economic indicators do not correlate with the national cybersecurity index. In the third stage, the authors used the principal components method to eliminate multicollinearity, forming three statistically significant components. In the fourth stage, countries were clustered using the k-means method, resulting in 5 sectors depending on the level of countries cybersecurity and socio-economic development. As a result, the segments were formed by countries with similar values, both the national cybersecurity index and indicators of socio-economic development. The data were resampled in the fifth stage to balance the observations depending on the selected classification groups-clusters. In the sixth stage, a decision tree classification model was built, which has high indicators of overall accuracy for each classification group. The model can be used to predict probable segments of socio-economic development of countries based on their cybersecurity.

Two integrated conceptual–wavelet-based data-driven model approaches for daily rainfall–runoff modelling
Authors: Sezen Cenk , Partal Turgay
Published: June 2022

Rainfall–runoff modelling is crucial for enhancing the effectiveness and sustainability of water resources. Conceptual models can have difficulties, such as coping with nonlinearity and needing more data, whereas data-driven models can be deprived of reflecting the physical process of the basin. In this regard, two hybrid model approaches, namely Génie Rural à 4 paramètres Journalier (GR4 J)–wavelet-based data-driven models (i.e., wavelet-based genetic algorithm–artificial neural network (WGANN); GR4 J–WGANN1 and GR4 J–WGANN2), were implemented to improve daily rainfall–runoff modelling. The novel GR4 J–WGANN1 hybrid model includes the outflow (QR) and direct flow (QD) obtained from the GR4 J model, and the GR4 J–WGANN2 hybrid model includes the soil moisture index (SMI) obtained from the GR4 J model as input data. In hybrid models, wavelet analysis and the Boruta algorithm were implemented to decompose input data and select wavelet components. Four gauging stations in the Eastern Black Sea and Kızılırmak basins in Turkey were used to observe modelling performance. The GR4 J model exhibited poor performance for extreme flow forecasting. The novel GR4 J–WGANN1 approach performed better than the GR4 J–WGANN2 model, and the hybrid models improved modelling performance up to 40% compared to the GR4 J model. In this regard, integrated conceptual–wavelet-based data-driven models can be useful for improving the conceptual model performance, especially regarding extreme flow forecasting.
Exploring climate change trends in major river basins and its impact on the riverine ecology, fish catch and fisheries of the Peninsular region of India: Issues and a brief overview
Authors: Panikkar Preetha , Sarkar Uttam Kumar , Das Basanta Kumar
Published: June 2022

Riverine fisheries will have a knock-on effect due to the changes in water flow and increased irrigation in the agriculture sector to cope with the climate change impact. The present study showed a very high perception existing in the fishing community about climate change observed in the last 10 years. About 95% of fishermen understand temperature and sea levels are changing, whereas 91% responded that rainfall is changing and salinity also is increasing and 86% think extreme rainfall is affecting productivity. Moreover, though the monsoon period is shorter than the non-monsoon period, about 62.3% of the total fish catch in River Cauvery takes place during the monsoon. The variations in climate can enormously impact the inland fisheries, especially the riverine resources, their productivity and sustainability. With this view, it was attempted to: (i) investigate the changing climate trends in the major river basins of the Peninsular region of India over the decades, (ii) key drivers and its implication on the fish catch, biodiversity, inland fisheries, (iii) analyse the perception of the fishermen and (iv) suggest appropriate strategies like the development of climate-smart villages and waterbodies for livelihood and sustainable utilization of the invaluable biological resources.

Published: June 2022

New precautions have become part of our daily life since COVID-19 pandemic such as wearing masks, maintaining distance and disinfecting products bought from markets before using them which is exhausting. We aimed to test the inhibitory effect of Camellia sinensis (black tea) water extracts on respiratory viruses and the inhibition of viruses accumulated over different surface types after being soaked in water supplemented with the extracts. Two water extraction methods (extract A: maceration at 80 °C for 30 min and extract B: boiling for 40 min) were applied; extracts were analyzed by high-performance liquid chromatography to detect polyphenolic compounds. Results showed that 200 μg/ml of extract A and 50 μg/ml of extract B in water caused 100% inhibition of influenza A (enveloped virus) virus after 1.5 h and similar results were obtained for adenovirus (non-enveloped virus) but at the same concentration of extract A and at 100 μg/ml of extract B. Different surfaces (aluminum, glass, plastic or carton, vegetables of smooth (tomato) or rough (lemon) surfaces and green leaves) were inoculated with both viruses for 20 min and then soaked in the water supplemented with 200 μg/ml of extract A or 100 μg/ml of extract B for 1.5 h, and this resulted in complete inhibition of both viruses.

Published: June 2022

Resumo: o campo de pesquisa deste artigo é a Sociologia da Música a partir da problematização da questão cultural e sua relação com a sociedade brasileira contemporânea. Para isso, foi analisada a versão do challenge da música “Aí Calica” no TikTok e de duas imagens, a primeira publicada na plataforma do Instagram e a outra nos canais oficiais do Governo Federal. Buscamos desvelar os sintomas de uma associação entre a hibridação presente na música, na tecnologia e na violência através da incorporação e da normatização da imagem e do som do fuzil. Dessa forma, ao reforçar o comum e o ordinário da violência através do agenciamento de culturas, também são intensificados e legitimados os conflitos contra negros, pobres e moradores de periferias. Pode-se também através da cultura, construir um dos espaços para se pensar e se fazer uma outra forma de agir e de ser sociedade que não negue o conflito e a violência, mas que os problematizem também na música.
PENGARUH KETINGGIAN DAN SUDUT KEMIRINGAN SALURAN AIR TERBUKA TERHADAP PARAMETER ALIRAN DAN PUTARAN TURBIN VORTEX
Authors: Febriyanto Yosafat Didik , Anis Samsudin
Published: June 2022

The stream parameter was affected by the height of falling, water debit and head losses. The stream that had straight flow could be converted to vortex stream using shapping drain. The movement of the vortex stream could be converted to mechanical energy using vortex wheel. The aim of this study was to find out the effect of the height and angle in exposed water drain in stream parameter and the spinning of vortex wheel. This study used type U water drain which has different variation of height 50 mm, 80 mm, 110 mm, 140 mm, and 170 mm and different angle variation 20, 25, and 30. The stream parameter was obatined by measuring the stream surface. Furthermore, the spinning of the vortex wheel was measured using tachometer. The result of this study showed that the spinning of the vortex wheel has the highest point at 100 mm in height variation and 30 in angle variation, which has 142.85 rpm in spinning speed, 1.178 m/s in stream speed, and 102.5 mm water height in vortex in average. It was because the higher and bigger the angle, the faster the stream was. However, a high speed of the stream produced small vortex stram. It caused the area of the water to hit in temperature to decrease so that the spinning of the wheel decreased.

The utilization of briquettes as a source of electricity generation is still low due to the briquette characteristics that have high moisture content. This research analyzes the briquette's potential as a source of electrical energy by utilizing its syngas with microturbine gas. The high quality of syngas can be reached by the optimal combustion chamber design. Therefore, the research aim is to be able to design the optimum combustion chamber for the briquette combustion process to generate the syngas. This research method uses two steps, i.e., the design of the combustion chamber and numerical analysis of the briquette combustion process through Computational Fluid Dynamics (CFD) simulations. Numerical analysis of the combustion process using three types of briquettes with different inorganic waste compositions, i.e., K1 type, K2 type, and K3 type. The research results explain the optimum design of the combustion chamber with a total length dimension of 220 mm, an inlet fuel section, and combustion chamber-syngas pipeline diameter of 50 mm and 75 mm, respectively. In addition, the dimensions of the primary air holes are 7 mm, and the secondary air holes are 5 mm. Type K1 briquettes are capable of producing syngas (kg/s) consisting of 6.9x10-13 CO, 3.04x10-31 H2, and  1.8x10-20 CH4. That syngas composition includes in the criteria of syngas in the microturbines gas that produce electric power of 2.3-2.5 kW. The conclusions explain that the combustion chamber can be added to the microturbine gas component, and K1 type briquette can be a solid fuel.

The purpose of this study was to determine the effect of misalignment distance of Cooling Tower drive shaft on normal stress and shear stress. Tensions that occur on the shaft continuously for a long time cause the shaft to experience fatigue. The greater misalignment distance will not only damage the shaft but can damage other components. For this reason, the misalignment of the cooling tower shaft is very important to study. This study uses a simulation method by first making a design drawing of the cooling tower drive shaft. Determine the material of the shaft and coupling, then perform simulations and analyze the results. The results of the Von Misses test at the highest and lowest voltages did not show a significant difference this was caused by the voltage difference that was not too far away. The shaft bears varying loads, causing stress along the shaft which results in rapid fatigue. These characteristics are associated with increased load and all indicate that misalignment reduces the life and reliability of the motor and its components. Based on the results of the Von Misses test and the lowest risk displacement that occurs to the effect of this misalignment is the misalignment distance (md = 1 mm), the higher the md value, the greater the risk that occurs to the cooling tower drive shaft.

This research aims to establish the effects of the length of the activated carbon-based medium on exhaust gas emission and evaluate the engine's corresponding performance. The method utilizes peat soil as the source of activated carbon. The soil is dried and then passed through a 30-mesh sieve. It is further heated to 400°C for an hour, soaked in a 25-percent H2SO4 solution, and then maintained at 120°C in an oven. The resulting activated carbon is then packed into an absorbent tube with a diameter of 30 mm and a varying length of 60 mm, 70 mm, and 80 mm. The tube is appended to the leaving end of a Honda Supra 125 X's muffler. The result suggests that the lowest emission is achieved when the tube length is 80 mm and at 2000 rpm of engine speed, i.e., with CO level of 2.57 percent and HC of 228 ppm. On the other hand, the highest emission is given by the tube length of 60 mm, i.e., with an HC level of 1437 ppm. In conclusion, it shows that the tube length affects the absorbent ability in reducing emission, but it does not significantly affect the engine's performance.

Mediastinal lymphohemangioma is a very rare, benign, congenital malformation. Mediastinal lymphohemangioma originates from local proliferation of lymphatic vessels. This disorder is accountable for 4.5% among all mediastinal tumors. Most lymphohemangiomas are found in the neck and axillary region among children, whereas only 1% are found in the mediastinum and tend to occur in individuals aged over 20 years old. A proper understanding is needed to be able to make a diagnosis and perform effective management of mediastinal lymphohemangiomaIn this case report, a woman with a diagnosis of mediastinal lymphohemangioma, established through a multidisciplinary approach covering the fields of pulmonology, thoracic and cardiovascular surgery, radiology, and anatomical pathology.Keywords: Mediastinal Lymphohemangioma, Core Biopsy, Thoracotomy

Background: Although classified as a rare disease, the global burden of disease study reports showed that interstitial lung disease is ranked 40th in the diseases with high mortality, and its prevalence had increased by 86% since 1990. The most common interstitial lung disease”idiopathic pulmonary fibrosis (IPF)”has low survival rates”2-3 years after diagnosis”and is irreversible. Establishing a definite diagnosis of IPF is very difficult because it needs a multidisciplinary approach, as an establishment based on the description of HRCT and lung biopsy is needed. The goal of therapy is to prevent the progression of fibrosis.
Case: We report a case of an adult woman, 46 years old with idiopathic pulmonary fibrosis (IPF) with Probable Usual Interstitial Pneumonia (UIP) pattern at dr. Saiful Anwar Hospital. History taking, physical examination and laboratory and chest Xray examination of the patient found a suspicion of ILD. CT-scan showed fibrosis in both lungs, honeycomb appearance with pulmonary bronchiectasis traction, which fit the description of IPF, and thus suspended the diagnosis of ILD. VATS pulmonary biopsy confirmed the diagnosis of IPF. The patient experienced a decrease in clinical conditions, as her complaint was worsening in the last month, in accordance to the state of acute exacerbations.
Conclusion: In this patient, the diagnosis of IPF with Probable UIP pattern was made through a multidisciplinary approach, including the pulmonology, radiology and anatomical pathology department.

The leaf-cuttíng ant Atta mexicana (F. Smith) removes the colony refuse out of the nest, forming typical mounds that attract many animáis. The purpose of this work was to study the insects living in the detritus. Forty nine species belonging in 9 orders were found; Coleptera constituted 51% of the total number of species, Collembola 16.3% and Díptera 10.2%. According to the developmental stages found in the refuse mounds, three categories were established: permanent, temporal and casual species. The entomofauna is aiso divided in oblígate and facultativa ¡nquilines. Seasonal populatíon changes are described taking the mound as a unit and divídíng it in three levels. The highest abundance was found in the dry and cool season. Trophíc categories are established for the entomofauna. The shelter and food resource roles that detritus play in the area are díscussed. The known information on insects associated with Atta refuse mounds is tabulated.

We studied the taxonomy of the Proculini genus Petrejoi- des Kuwert based on 600 specimens from dífferent mexican and central american locali- ties. We established the phyietic relationships of this genus within the tribe Proculini by defining 12 species, four of these species endemic to México are descríbed here. In the genus Petrejoides we distinguished three phyietic Unes. Orizabae line: composed by P. orizabae Kuwert, P. silváticas sp. nov. (MEXICO: Nuevo León; northern Sierra Madre Oriental, Chipinque-Cola de Caballo región), P. subrecticornis (Kuwert), P. jalapensis (Bates) and P. guatemalae Reyes-Castillo and Schuster. Laticornis Wne: oniy P. laticornis (Truqui). "Recticornis line: composed by P. recticornis (Burmeister), P. nebulosas sp. nov. MEXICO: Hidalgo: cloud forest in the vicinity of Tenango de Doria), P olmecae sp. nov. (MEXICO: Guerrero: wet slopes of the Sierra Madre del Sur, distributed through the cloud forest in the Omiltemi región), P. imbe- 2 Castillo, C. y P. Reyes-Castillo. Blosistemática de Petrejoides llis (Casey), P. mazatecus sp. nov. (MEXICO: Oaxaca: Sierra de Zongolica of the Sierra Madre Oriental, cloud forest in the vincity of Huautia de Jiménez), and P. tenuis Kuwert. We discussed the taxonomic characters and affinities of these three phyietic línes and we inelude an Identification key of the species. Every species is described or redescribed, discussing their varíations and affinities^ synonyms and com- ments, and are depicted for a better understanding of taxonomic characters used for description. Based on taxonomic affinities, ecological requirements and geographical distribution, we concluded that Petrejoides shows the Mesoamerican Mountain dispersal pattern with projections into Southern Central America. This is a typical montane taxa, preferently hygrophilous and completely sylvicolous. It shows a great diver- sification in the mountains located northwesterly to the Istmo de Tehuantepec, where the three phyietic lines oceur and is rich in endemic forms. In the Central American Nucleus, assumed as the origin area of Petrejoides, there is a low number of species which is, ap- parently, relatad with the diversification of Chondrocephalus these two genera have the highest affinities and share their rangas. In the Mexican Transition Zone speciation processes and the establishment of dispersal patterns of Petrejoides are highiy influenced by the distribu- tion and evolution of the cloud forest. The invasión of the mountains located to the north- west of the Istmo de Tehuantepec, probably was an event carried out in the earlier stages of the evolution of this genus. We assumed it based on the presence in this area of plesio- morphic and apomorphic species. opposed to the invasión of Southern Central America (Costa Rica, Panama) which has been a relatively recent event.
