TBX5-AS1 is differentially expressed in brain metastatic human breast cancer.
Authors: Mamoor Shahan
Published: June 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that TBX5 antisense RNA 1, encoded by TBX5-AS1, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. TBX5-AS1 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of TBX5-AS1 in primary tumors was correlated with patient overall and recurrence-free survival. Modulation of TBX5-AS1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Basic Human Values and the Adoption of Cryptocurrency
Authors: Stanciu Adrian , Bernardes Mariana , Partsch Melanie Viola , Lechner Clemens M.
Published: June 2023

Cryptocurrency is an attempt to create an alternative to centralized financial systems using blockchain technology. However, our understanding of the psychological mechanisms that drive cryptocurrency adoption is limited. This study examines the role of basic human values in three stages of cryptocurrency adoption–awareness, intention to buy, and ownership–using the Theory of Planned Behavior (TPB). Logistic regression analysis was conducted on a quota sample of 714 German adults, and the results showed that openness-to-change values increased the likelihood of cryptocurrency awareness, while self-enhancement values increased the likelihood of intention to buy and ownership. These findings were consistent even after controlling for demographic characteristics, attitudinal beliefs, and perceived behavioral control, which are important factors in the TPB. The results suggest that basic human values may influence an individual's decision to adopt cryptocurrency, but the transition from awareness to ownership may be influenced by socio-economic opportunities available to interested individuals.

Authors: Rimal Suspana , Pokhrel Bibek , Shrestha Sunil , Pradhan Bharat
Published: June 2023

The RC-framed building is one of the most common construction techniques for seismic-resistant structures due to its ductile nature. But the seismic performance of the RC structure is affected by various factors among which site soil condition is vital. The sub-soil condition affects the time period of the structure which eventually impacts the earthquake force in the structure, thus making variations in seismic loadings. Although several studies have been performed and design elastic spectra have been defined as per soil types in the design codes, there are no studies quantifying the effect of design demand in the buildings due to variation of soil type in the context of Nepal and NBC 105:2020. Therefore, this study aims to present the variation in design demand for moderately high-rise RC buildings in different soil types. A representative sample building has been taken and analyzed in the Finite Element platform SAP 2000. Numerical analysis is performed using linear static and response spectrum methods. Based on the study, variation in the base shear, story displacement, inter-story drift, and section size to meet the limit state of strength are compared for soil types A, B, C, and D.

Thermo-optic coefficient of chemical vapor deposited graphene multilayers
Authors: Arpana Agrawal
Published: June 2023

Observation of strong inelastic light-matter interaction and large thermal conductivity of novel two-dimensional graphene has invigorated the present research. Herein, the thermo-optic coefficient of graphene multilayers is obtained from their nonlinear refraction coefficients calculated from Z-scan experiment in closed aperture geometry. The refractive optical nonlinearity was obtained employing a continuous wave He-Ne laser and occurs due to thermal lensing effect. The graphene multilayers behave as the diverging (concave) lens giving rise to self-defocusing effect leading to negative sign of refractive nonlinearity. Accordingly, a large negative thermo-optic coefficient (-2.43×10-3 K-1) inferred for the graphene multilayers suggests its utility for thermo-optic device applications.

A Review: Keystone Environmental Problems are the Labyrinth Root causes that Resonate together with Socioeconomic Factors on Igniting Global Conflicts and Warfare
Authors: S. Sivaramanan
Published: June 2023

When mitigating a man-made environmental problem, if it results in the permanent disappearance of one or more other environmental problems, then that mitigated problem can be considered a keystone environmental problem. Based on the aforesaid definition, eight environmental problems have been identified, such as population explosion, air pollution, deforestation, water pollution, scarcity and salination, overexploitation of natural resources, urbanisation (including industrialization, urban sprawl and settlements), intensive farming, and the global energy crisis. It has also been found that there is a significant relationship between these keystone environmental problems and global conflicts. For instance, according to the United Nations Environmental Programme (UNEP), over the last six decades, globally, more than 40% of the internal conflicts have been caused by overexploitation of natural resources, which is a known keystone environmental issue. Thus, the importance of identifying the role of keystone environmental problems in igniting global environmental conflicts and warfare has been widely realised. This study was conducted using qualitative content analysis methodology reveals that labyrinth established by root keystone environmental problems resonates together with socio-economic factors conflagrate global environmental conflicts and warfare, such as Cauvery River conflict between Tamil Nadu and Kerala States in South India, conflict from trespassing fishermen poaching in waters of neighbouring country from both India and Sri Lanka, Environmental Conflict in Northeast India and Bangladesh due to flooding (natural disaster) caused by climate change led to migration, West bank water crisis between Israel and Palestine, Russia’s invasion into Ukraine in 2022, Alto Cenepa war, Grand Ethiopian Renaissance Dam (GERD) crisis between Ethiopia and Egypt, environmental conflicts in Philippines, conflict for land resources in Ethiopia, environmental conflict in Mexico, environmental conflict in Peru, Northeast India, Pakistan, Israel (Gaza), conflict of Mauritania and Senegal, Israel-Palestine (West bank), Somalia- Ethiopia, El Salvador-Honduras, Conflict between Kenyan tribes, dispute between North and South Sudan, and transboundary air pollution (causing acid rain) issue between the USA and Canada.

Quatro ratos machos Wistar experimentalmente ingênuos foram submetidos a 10 sessões de treino discriminativo (múltiplo VI 15 s / Extinção), 28 sessões de treino discriminativo durante a exposição ao CMS e cinco sessões de treino discriminativo após a exposição ao protocolo de estressores. Como resultado, houve diminuição dos índices discriminativos e aumento no número de respostas emitidas por sessão nas duas primeiras semanas de exposição ao protocolo de estressores, e reversão dessas medidas nas duas semanas seguintes. A frequência de reforçamento se manteve relativamente constante ao longo de todo o estudo. Quando o CMS foi interrompido, a maioria dos sujeitos apresentou índices discriminativos superiores aos observados na linha de base. Esses dados sugerem que as primeiras semanas de exposição ao protocolo de estressores pode gerar disrupção no controle discriminativo previamente estabelecido.

Artificial seed merupakan benih buatan yang dibuat dengan teknik enkapsulasi. Keuntungan artificial seed adalah lebih potensial untuk penyimpanan yang lama tanpa kehilangan viabilitas, lebih mudah dalam proses transportasi, skala produksi besar dengan biaya produksi yang rendah. Sistem enkapsulasi pada kakao dilakukan karena penyediaan bibit dengan mengecambahkan benih belum mampu memenuhi kebutuhan bibit kakao. Benih kakao termasuk benih rekalsitran jika disimpan harus mengandung air di atas 20%, tidak tahan dikeringkan, dan tidak tahan disimpan pada temperatur rendah. Pada proses enkapsulasi, eksplan yang telah dibungkus dengan sodium alginat direndam dalam larutan CaCl2.2H2O untuk menambah kekerasan dan kekakuan kulit kapsul. Oleh karena itu, konsentrasi dari bahan penyalut dan larutan CaCl2.2H2O serta waktu perendaman harus optimal. Penelitian ini bertujuan untuk mengetahui kombinasi yang tepat antara konsentrasi Na-alginat, CaCl2.2H2O dan waktu perendaman. Penelitian ini dilaksanakan di Laboratorium Kultur Jaringan Fakultas Pertanian Universitas Jember. Data diamati berdasarkan kualitas kapsul, berdasarkan 2 faktor perlakuan. Faktor pertama adalah Konsentrasi Na-alginat (N) yang terdiri atas 3 taraf, 2%; 2,5% dan 3%. Faktor kedua adalah waktu perendaman pada larutan gr CaCI.2H2O (W) , 5; 10; 15; 20 dan 30 menit. Setiap kombinasi perlakuan diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa produksi artificial seed menggunakan 2,5% Na-alginat yang dilarutkan dalam MS0, dan direndam dalam larutan 100 mM CaCl2.2H2O. selama 15 menit memiliki kekerasan kapsul yang optimal.

ABSTRAK

Kematian ibu merupakan masalah kesehatan global yang menjadi indikator penting dalam keberhasilan program kesehatan ibu dan merupakan salah satu indikator untuk menggambarkan derajat kesehatan masyarakat. Penelitian ini menggunakan pendekatan kualitatif, dengan desain penelitian studi kasus. Teknik pengumpulan data pada penelitian ini dengan studi dokumentasi, observasi dan wawancara mendalam. Hasil Penelitian ini menunjukkan karakteristik aktor kebijakan JKN-BPJS dalam upaya penurunan Angka Kematian Ibu (AKI) pada implementasi kebijakan: usia, jenis kelamin, institusi asal, jabatan, lama berkerja, dan latar belakang pendidikan, dimana setiap aktor kebijakan memiliki pengaruh sendiri dalam implementasi kebijakan. Melalui identifikasi masalah diperoleh 3 peta masalah yang kemudian melalui form Delphi diprioritaskan masalah kebijakan sebagai berikut; 1). Keterbatasan akses perempuan (ibu hamil) terhadap fasilitas pelayanan kesehatan terutama bagi perempuan miskin di daerah terpencil tertinggal dalam program BPJS,              2). Kurangnya pemahaman peran dan tupoksi pelaksana program JKN-BPJS, 3). Sistem rujukan dari rumah ke Puskesmas dan ke Rumah Sakit belum berjalan optimal dan Fasilatas di Puskesmas yang tidak sesuai Standar. Rekomendasi yang diberikan berdasarkan prioritas masalah kebijakan berupa: 1). PERMENKES RI No 4 Tahun 2019 dan Peraturan Badan Peyelenggaraan Jaminan Sosial Kesehatan, 2). Sosialiasi PERMENKES RI No 4 Tahun 2019 dan Peraturan Badan Peyelenggaraan Jaminan Sosial Kesehatan PERMENKES No. 52  Tahun 2016 (Ibu Hamil, Masyarakat, Desa, dan Kecamatan), dan 3). Pembentukan kader dalam pelaksanaan program JKN-BPJS dalam penurunan AKI.

Kecoa (Periplanetta sp.) adalah salah satu serangga rumah tangga yang paling umum kita temukan di berbagai tempat. Kecoa juga menjadi vektor mekanis untuk beberapa penyakit seperti diare, keracunan makanan, tipus, disentri, polio, hepatitis a, dan cholera. Hal ini karena tubuh kecoa mampu mentransmisikan bakteri patogen seperti Salmonella sp., Staphylococcus sp., Streptococcus sp., Shigella sp. dan bakteri patogen lainnya. Cara pengendalian yang biasa digunakan selama ini adalah secara kimiawi menggunakan insektisida kimia yang memiliki dampak negatif terhadap manusia dan lingkungan. Penggunakan insektisida nabati diperlukan agar mengurangi kerusakan lingkungan yang diakibatkan oleh zat kimia. Daun bahagia (Dieffenbachia sp.) memiliki kandungan senyawa flavonoid dan minyak atsiri yang berkhasiat sebagai daya zat penolak (repellent) dan anti mikroba. Kandungan ekstrak daun Bahagia (Dieffenbachia sp.) dapat mengganggu sistem respirasi yang dapat mematikan kecoa (Periplanetta sp.). Kontrol positif menggunakan insektisida kimia dan ekstrak Daun Bahagia (Dieffenbachia sp.) menghasilkan jumlah mortalitas yang sama, akan tetapi pada menit ke lima, kontrol positif lebih cepat waktu mortalitasnya dibandingkan ekstrak daun Bahagia (Dieffenbachia sp.). Penggunaan daun Bahagia (Dieffenbachia sp.) berpotensi menjadi insektisida alami yang ramah lingkungan dan mudah didapatkan karena daun Bahagia (Dieffenbachia sp.) memiliki kandungan yang dapat membasmi serangga yaitu flavonoid dan minyak atsiri.
