Authors: Caetano Fernanda Aparecida , Toscano Carlos 
Published: May 2024

O presente artigo é parte de um episódio que compõe os dados de uma dissertação de mestrado intitulada “O aprendizado da matemática no ensino fundamental: um estudo com uma turma do 2º ano”, defendida em 2014 na UEL – Universidade Estadual de Londrina e focaliza o desenvolvimento de uma atividade de ensino de matemática em uma turma do 2º ano do Ensino Fundamental em uma escola pública do interior do estado de São Paulo, onde tivemos por objetivo compreender o aprendizado da matemática na apropriação dos conceitos pretendidos em uma atividade proposta, levando em conta o uso e reflexões de materiais manipuláveis como apoio na atividade. Para o trabalho nos ancoramos nos pressupostos teóricos da psicologia histórico-cultural e seus colaboradores. Como aporte metodológico da pesquisa tomamos como referência a abordagem microgenética, que tem como característica o exame orientado para o funcionamento dos sujeitos focais, as relações intersubjetivas e as condições sociais da situação, resultando num relato minucioso dos acontecimentos. Para coleta de dados fizemos se uso de observações, videogravações e um diário de campo, para posterior transcrição dos dados. Os dados foram analisados à luz da abordagem enunciativa discursiva proposta por Volochínov. Como resultado destacamos que a presença do material manipulável não produz, por si só, o aprendizado dos alunos. Faz-se necessário uma problematização do papel deste material no processo de ensino, do seu uso intencional e colaborativo de modo que esteja articulado à atividade mental pretendida que promova avanços na apropriação de conceitos matemáticos dos alunos.

El uso continuado de productos químicos para eliminar o reducir las poblaciones de mosquitos a un nivel tolerable desarrolla resistencias con el tiempo. Se exploran extractos de plantas como alternativas para mitigar su incidencia en el medio ambiente. El estudio comparó las eficacias larvicidas de cinco productos botánicos autóctonos frente a los estadios larvales de Aedes aegypti y Culex quinquefasciatus. Grupos de treinta larvas de de estadio 1 a 3 de Ae. aegypti y Cx. quinquefasciatus se expusieron a 5, 10 y 15 mg/100 ml de los extractos de los productos botánicos analizándose en laboratorio su actividad larvicida a las 24, 48 y 72 horas. Los extractos de Morinda lucida y Vernonia amygdalina fueron los más efectivos frente a los estadios larvarios 1 a 3 de Ae. aegypti y Cx. quinquefasciatus.
Mosquitoes are known to develop resistance over time while using chemicals to eliminate or reduce their population to tolerable level. Plant extracts are explored as alternatives to mitigate their incidence in the environment. The study compared the larvicidal efficacies of five different indigenous botanicals against the larval stages of Aedes aegypti and Culex quinquefasciatus. Batches of thirty 1st-3rd instar larvae of Ae. aegypti and Cx. quinquefasciatus were exposed to 5, 10 and 15mg/100ml of the crude extracts of the botanicals respectively and they were assayed in the laboratory for larvicidal activities for 24, 48, and 72hrs post exposure. Morinda lucida and Vernonia amygdalina extracts were the most effective against 1st-3rd instars of Ae. aegypti and Cx. quinquefasciatus.

El primer registro de Aedes albopictus en el Estado de Pará, en la Amazonía brasileña, se realizó en 2003. Este estudio tuvo como objetivo describir la fauna de culícidos y la abundancia de Ae. albopictus en cuatro áreas con diferentes grados de antropización en la ciudad de Belém-PA. Para ello, se colectaron larvas en criaderos naturales, comprobando que Ae. albopictus correspondió al 63,4% de los mosquitos colectados, siendo predominante en las áreas más antropizadas. También conseguimos describir dos haplotipos derivados de secuencias parciales del gen COI de 16 mosquitos del área de mayor grado de antropización, los cuales se agrupan con ejemplares de países tropicales y de clima templado, respectivamente. Nuestros resultados demuestran la adaptación de Ae. albopictus a las áreas urbanas de la región amazónica.
The first record of Aedes albopictus in the State of Pará, in the Brazilian Amazon, was carried out in 2003. The present study aimed to describe the Culicidae fauna and the abundance of Ae. albopictus in four areas with different degrees of anthropization, in the city of Belém-PA. For this, larvae were collected in natural breeding sites, proving that Ae. albopictus corresponded to 63.4% of the mosquitoes collected, being the predominant species in areas with the highest degree of anthropization. We also identified two haplotypes derived from partial sequences of the COI gene of 16 mosquitoes from the area with the greatest degree of anthropology, which are grouped with specimens from tropical and temperate countries, respectively.

Hoạt động nạo vét cảng là quá trình sử dụng các thiết bị nạo vét loại bỏ bùn cát trong cảng để tạo ra một khu vực cảng có độ sâu lớn hơn nhằm nâng cao khả năng tiếp nhận tàu, tăng cường năng lực vận chuyển hàng hóa và phát triển hoạt động thương mại tại cảng. Quá trình này khiến cho bùn cát ở đáy biển bị dao động và lan truyền đến các khu vực xung quanh, ảnh hưởng đến môi trường sống của các loài sinh vật biển như rạn san hô, thảm cỏ biển và các loại hải sản khác. Trong nghiên cứu này mô hình MIKE 3 được ứng dụng để mô phỏng chế độ thủy động lực và quá trình lan truyền độ đục từ hoạt động nạo vét bùn cát ở khu vực cảng Nghi Sơn, tỉnh Thanh Hóa trong điều kiện gió mùa. Kết quả nghiên cứu cho thấy tốc độ dòng chảy ven bờ ở khu vực cảng trong thời kỳ gió mùa Tây Nam lớn hơn so với thời kỳ gió mùa Đông Bắc. Quá trình lan truyền độ đục từ hoạt động nạo vét bùn cát phụ thuộc lớn vào chế độ dòng chảy trong cảng Nghi Sơn. Cụ thể, sau 4 tuần thi công nạo vét nồng độ bùn cát ở khu vực trong cảng đạt giá trị 1,2 kg/m3, khu vực ven biển phía ngoài cảng có nồng độ bùn cát giảm xuống còn khoảng 0,15 kg/m3. Sau 6 tuần thi công nạo vét trong cảng trường độ đục bùn cát có xu thế di chuyển rộng ra phía ngoài cảng có nồng độ bùn cát đạt giá trị 0,015 kg/m3 do sự tác động của dòng chảy thủy triều, sau 8 tuần thi công nồng độ bùn cát có xu hướng di chuyển đến khu vực kè biển phía ngoài cảng và có nồng độ bùn cát đạt giá trị khoảng 0,08 kg/m3. Sau 10 tuần thi công trường độ đục được phân tán dọc theo bờ biển ở phía Nam cảng Nghi Sơn với nồng độ bùn cát đạt giá trị khoảng 0,004 kg/m3.
Similar and divergent responses to salinity stress of jamun (Syzygium cumini L. Skeels) genotypes
Authors: Singh Anshuman , Kumar Ashwani , Prakash Jai , Verma Arvind Kumar 
Published: May 2024

Background
Genetic variation for salt tolerance remains elusive in jamun (Syzygium cumini).

Methods
Effects of gradually increased salinity (2.0–12.0 dS/m) were examined in 20 monoembryonic and 28 polyembryonic genotypes of jamun. Six genotypes were additionally assessed for understanding salt-induced changes in gas exchange attributes and antioxidant enzymes.

Results
Salt-induced reductions in leaf, stem, root and plant dry mass (PDM) were relatively greater in mono- than in poly-embryonic types. Reductions in PDM relative to control implied more adverse impacts of salinity on genotypes CSJ-28, CSJ-31, CSJ-43 and CSJ-47 (mono) and CSJ-1, CSJ-24, CSJ-26 and CSJ-27 (poly). Comparably, some mono- (CSJ-5, CSJ-18) and poly-embryonic (CSJ-7, CSJ-8, CSJ-14, CSJ-19) genotypes exhibited least reductions in PDM following salt treatment. Most polyembryonic genotypes showed lower reductions in root than in shoot mass, indicating that they may be more adept at absorbing water and nutrients when exposed to salt. The majority of genotypes did not exhibit leaf tip burn and marginal scorch despite significant increases in Na+ and Cl−, suggesting that tissue tolerance existed for storing excess Na+ and Cl− in vacuoles. Jamun genotypes were likely more efficient in Cl− exclusion because leaf, stem and root Cl− levels were consistently lower than those of Na+ under salt treatment. Leaf K+ was particularly little affected in genotypes with high leaf Na+. Lack of discernible differences in leaf, stem and root Ca2+ and Mg2+ contents between control and salt treatments was likely due to their preferential uptake. Correlation analysis suggested that Na+ probably had a greater inhibitory effect on biomass in both mono- and poly-embryonic types. Discriminant analysis revealed that while stem and root Cl− probably accounted for shared responses, root Na+, leaf K+ and leaf Cl− explained divergent responses to salt stress of mono- and poly-embryonic types. Genotypes CSJ-18 and CSJ-19 seemed efficient in fending off oxidative damage caused by salt because of their stronger antioxidant defences.

Conclusions
Polyembryonic genotypes CSJ-7, CSJ-8, CSJ-14 and CSJ-19, which showed least reductions in biomass even after prolonged exposure to salinity stress, may be used as salt-tolerant rootstocks. The biochemical and molecular underpinnings of tissue tolerance to excess Na+ and Cl− as well as preferential uptake of K+, Ca2+, and Mg2+ need to be elucidated.
A comprehensive analysis of the oncogenic and prognostic role of TBC1Ds in human hepatocellular carcinoma
Authors: Zhang Pei , Zhu Lei , Pan Xiaodong 
Published: May 2024

Backgrounds
TBC1D family members (TBC1Ds) are a group of proteins that contain the Tre2-Bub2-Cdc16 (TBC) domain. Recent studies have shown that TBC1Ds are involved in tumor growth, but no analysis has been done of expression patterns and prognostic values of TBC1Ds in hepatocellular carcinoma (HCC).

Methods
The expression levels of TBC1Ds were evaluated in HCC using the TIMER, UALCN and Protein Atlas databases. The correlation between the mRNA levels of TBC1Ds and the prognosis of patients with HCC in the GEPIA database was then analyzed. An enrichment analysis then revealed genes that potentially interact with TBC1Ds. The correlation between levels of TBC1Ds and tumor-infiltrating immune cells (TIICs) in HCC were studied using the TIMER 2.0 database. Finally, a series of in vitro assays verified the role of TBC1Ds in HCC progression.

Results
This study revealed the upregulated expression of TBC1Ds in HCC and the strong positive correlation between the mRNA levels of TBC1Ds and poor prognosis of patients with HCC. The functions of TBC1Ds were mainly related to autophagy and the AMPK pathway. There was also a significant correlation between level of TBC1Ds and tumor-infiltrating immune cells (TIICs) in HCC. The promoting role of TBC1Ds in HCC progression was verified in vitro assays.

Conclusion
The results of this analysis indicate that TBC1Ds may serve as new biomarkers for early diagnosis and treatment of HCC.
Arsenic disulfide promoted the demethylation of PTPL1 in diffuse large B cell lymphoma cells
Authors: Chen Chen , Wang Ling , Liu Yan , Du Shenghong , Teng Qingliang 
Published: May 2024

Background
Promoter hypermethylation of the tumor suppressor gene is one of the well-studied causes of cancer development. The drugs that reverse the process by driving demethylation could be a candidate for anticancer therapy. This study was designed to investigate the effects of arsenic disulfide on PTPL1 methylation in diffuse large B cell lymphoma (DLBCL).

Methods
We knocked down the expression of PTPL1 in two DLBCL cell lines (i.e., DB and SU-DHL-4 cells) using siRNA. Then the DLBCL proliferation was determined in the presence of PTPL1 knockdown. The methylation of PTPL1 in DLBCL cells was analyzed by methylation specific PCR (MSPCR). The effect of arsenic disulfide on the PTPL1 methylation was determined in DLBCL cell lines in the presence of different concentrations of arsenic disulfide (5 µM, 10 µM and 20 µM), respectively. To investigate the potential mechanism on the arsenic disulfide-mediated methylation, the mRNA expression of DNMT1, DNMT3B and MBD2 was determined.

Results
PTPL1 functioned as a tumor suppressor gene in DLBCL cells, which was featured by the fact that PTPL1 knockdown promoted the proliferation of DLBCL cells. PTPL1 was found hypermethylated in DLBCL cells. Arsenic disulfide promoted the PTPL1 demethylation in a dose-dependent manner, which was related to the inhibition of DNMTs and the increase of MBD2.

Conclusion
Experimental evidence shows that PTPL1 functions as a tumor suppressor gene in DLBCL progression. PTPL1 hyper-methylation could be reversed by arsenic disulfide in a dose-dependent manner.

Published: May 2024

Applying organic manures is crucial for optimal radish growth and yield due to their rich nutrient content, soil-enriching properties and ability to foster beneficial microbial activity, all of which contribute to healthier plants and improved harvests. A field experiment was conducted to evaluate the influence of different liquid organic manures on growth and yield of radish (Raphanus sativus) at organic farming block of Zonal Agricultural Research Station, V. C. Farm, Mandya during late Kharif 2020. The experiment was laid in Randomized Complete Block Design with nine treatments and three replications. The experiment consisted of nine treatments of three different levels of nitrogen was applied through FYM and different times of application of Panchagavya and Jeevamrutha. A significant variation was observed among the treatments. The 75% RDN through FYM + two time application of Panchagavya significantly increased the growth and yield attributes at 15, 30, 45 DAS and at harvest viz., plant height (8.39, 18.25, 28.16 and 33.06 cm), number of leaves per plant (6.22, 9.11, 16.04 and 18.43), leaf area index (0.08, 0.46, 0.70 and 1.01), root diameter (5.43cm at harvest), fresh shoot weight (8.53, 51.31, 115.29 and 132.43 g plant-1), fresh root weight (2.99, 61.19, 161.08 and 213.08 g plant-1), dry shoot weight (1.11, 10.76, 22.01 and 30.49 g plant-1), dry root weight (0.90, 13.13, 26.74 and 43.28 g plant-1), root yield (38.38 t ha-1) and shoot yield (30.26 t ha-1). In total, the results suggested that 75 per cent recommended dosage of nitrogen was applied through FYM with two times application of panchagavya is proved to be conducive for radish cultivation.

The experiment carried out in this field study was between 2022 and 2023 at the (AICRP) research farm in the outward-bound farm of the College of Agriculture, Indore. Indore is a small city in the western part of Madhya Pradesh, Central India, situated on the Malwa Plateau. An experiment was conducted with three replication by using different combination of N, P levels and crop residues in RBD design. Experiment field was medium to black soil with pH of 7.63 and medium in organic carbon 0.58%. The soil was low in available nitrogen (208.0 kg/ha) medium in available phosphorus (21.0 kg/ha) and high in potassium (585 kg/ha) and divided into gross plot size of 10 x 7.2 m2 and a net plot size of 9 x 6.4 m2, respectively. During crop harvest four different depths were used to gather the soil samples: 0–10, 10–20, 20–30, and 30–40 cm. All the collected samples are examined separated for soil organic carbon, active (highly labile, labile SOC), and passive (non-labile, less labile SOC) carbon pools. The finding showed that maximum soil organic carbon (%) was observed with the application of treatment T6 treatment (FYM 6 t ha-1 + N20 P13. Similar trend was found with active (very labile, labile) and passive carbon (less labile, non-labile) pools of soil.
