Background: Primary brain tumors constitute the leading cause of cancer-related mortality. Among them, adult diffuse gliomas are the most common type, affecting the cerebral hemispheres and displaying a diffuse infiltrative pattern of growth in the surrounding neuropil that accounts for about 80% of all primary intracranial tumors. The hallmark feature of gliomas is blood vessel proliferation, which plays an important role in tumor growth, tumor biological behavior, and disease outcome. High-grade gliomas exhibit increased vascularity, the worst prognosis, and lower survival rates. Several angiogenic receptors and factors are upregulated in glioblastomas and stimulate angiogenesis signaling pathways by means of activating oncogenes and/or down-regulating tumor-suppressor genes. Existing literature has emphasized that different microvascular patterns (MVPs) are displayed in different subtypes of adult diffuse gliomas. Methods: We examined the distribution and biological characteristics of different MVPs in 50 patients with adult diffuse gliomas. Haematoxylin and eosin staining results, along with periodic acid–Schiff and CD34 dual-stained sections, were examined to assess the vascular patterns and correlate with different grades of diffuse glioma. Results: The present observational study on adult diffuse glioma evaluated tumor grade and MVPs. Microvascular sprouting was the most common pattern, while a bizarre pattern (type 2) was associated with the presence of a high-grade glioma. Vascular mimicry was observed in 6% of cases, all of which were grade 4 gliomas. Conclusions: This study supplements the role of neo-angiogenesis and aberrant vasculature patterns in the grading and progression of adult diffuse gliomas, which can be future targets for planning treatment strategies.

Race, Reason, and Emotion:Reading Pramoedya Ananta Toer’s House of Glass
Sony Karsono 한국동남아학회 2021 동남아시아연구 Vol.31 No.2
In the early 20th-century Dutch East Indies, through domestic espionage and scholarly research, the colonial state produced strategic knowledge about its Native subjects. The state used such knowledge to keep the Natives under control. House of Glass, the fourth and last novel in Pramoedya Ananta Toer’s “Buru Quartet,” offers a fictionalized historical account of how the domestic spy work and scholarly studies responded to the emergence of Native nationalist movement. This paper examines one product of the colonial state’s knowledge- production activities: the colonial discourse on Natives revolving around the notions of race, reason, and emotion. A critical reading of this discourse suggests that it contains not merely racial prejudices on the part of European colonial masters against Natives but also elements of truth about them. Pramoedya seems to have used the narrator Jacques Pangemanann to draw attention to the troubling weaknesses he saw in Indonesians, both in the colonial era and under the New Order.
A weighted Fourier series with signed good kernels
Sony Chan,임경수 대한수학회 2017 대한수학회보 Vol.54 No.3
It is natural to try to find a kernel such that its convolution of integrable functions converges faster than that of the Fej\'er kernel. In this paper, we introduce a weighted Fourier partial sums which are written as the convolution of signed good kernels and prove that the weighted Fourier partial sum converges in $L^2$ much faster than that of the Ces\`aro means. In addition, we present two numerical experiments.
Quantum-based exact pattern matching algorithms for biological sequences
Soni, Kapil Kumar,Rasool, Akhtar Electronics and Telecommunications Research Instit 2021 ETRI Journal Vol.43 No.3
In computational biology, desired patterns are searched in large text databases, and an exact match is preferable. Classical benchmark algorithms obtain competent solutions for pattern matching in O (N) time, whereas quantum algorithm design is based on Grover's method, which completes the search in $O(\sqrt{N})$ time. This paper briefly explains existing quantum algorithms and defines their processing limitations. Our initial work overcomes existing algorithmic constraints by proposing the quantum-based combined exact (QBCE) algorithm for the pattern-matching problem to process exact patterns. Next, quantum random access memory (QRAM) processing is discussed, and based on it, we propose the QRAM processing-based exact (QPBE) pattern-matching algorithm. We show that to find all t occurrences of a pattern, the best case time complexities of the QBCE and QPBE algorithms are $O(\sqrt{t})$ and $O(\sqrt{N})$, and the exceptional worst case is bounded by O (t) and O (N). Thus, the proposed quantum algorithms achieve computational speedup. Our work is proved mathematically and validated with simulation, and complexity analysis demonstrates that our quantum algorithms are better than existing pattern-matching methods.
Sony Shrestha,김용균 한국미생물학회 2009 The journal of microbiology Vol.47 No.6
An entomopathogenic bacterium, Xenorhabdus nematophila, induces an immunosuppression of target insects by inhibiting phospholipase A2 (PLA2) activity. Recently, an immune-associated PLA2 gene was identified from the red flour beetle, Tribolium castaneum. This study cloned this PLA2 gene in a bacterial expression vector to produce a recombinant enzyme. The recombinant T. castaneum PLA2 (TcPLA2) exhibited its characteristic enzyme activity with substrate concentration, pH, and ambient temperature. Its biochemical characteristics matched to a secretory type of PLA2 (sPLA2) because its activity was inhibited by dithiothreitol (a reducing agent of disulfide bond) and bromophenacyl bromide (a specific sPLA2 inhibitor) but not by methylarachidonyl fluorophosphonate (a specific cytosolic type of PLA2). The X. nematophila culture broth contained PLA2 inhibitory factor(s), which was most abundant in the media obtained at a stationary bacterial growth phase. The PLA2 inhibitory factor(s) was heat-resistant and extracted in both aqueous and organic fractions. Effect of a PLA2-inhibitory fraction on the immunosuppression of T. castaneum was equally comparable with that resulted from inhibition of the TcPLA2 gene expression by RNA interference.
