  • In this paper we study the numerical solutions of the stochastic differential equations of the form $$du(x,\;t)=f(x,\;t,\;u)dt\;+\;g(x,\;t,\;u)dW(t)\;+\;\sum\limits_{|q|\leq2m}\;A_q(x,\;t)D^qu(x,\;t)dt$$ where $0\;{\leq}\;t\;{\leq}\;T,\;x\;{\in}\;R^{\nu}$, ($R^{nu}$ is the $\nu$-dimensional Euclidean space). Here $u\;{\in}\;R^n$, W(t) is an n-dimensional Brownian motion, $$f\;:\;R^{n+\nu+1}\;{\rightarrow}\;R^n,\;g\;:\;R^{n+\nu+1}\;{\rightarrow}\;R^{n{\times}n},$$, and $$A_q\;:\;R^{\nu}\;{\times}\;[0,\;T]\;{\rightarrow}\;R^{n{\times}n}$$ where ($A_q,\;|\;q\;|{\leq}\;2m$) is a family of square matrices whose elements are sufficiently smooth functions on $R^{\nu}\;{\times}\;[0,\;T]\;and\;D^q\;=\;D^{q_1}_1_{\ldots}_{\ldots}D^{q_{\nu}}_{\nu},\;D_i\;=\;{\frac{\partial}{\partial_{x_i}}}$.

  • More then 120 species of higher fungi were collected in Mt. Muhack areas during the period from May, 1985 to September, 1986. These higher fungi were identified. As a result of identification, Hygrocybe ovina(Fr.) Kuhn., lnocybe albodisca Peck., I. calospora Que'I., and I. kobayasii Hongo were new to be Korea.

  • In order to determine of trace mineral elements of wild edible mushrooms in Korea, the dried carpophores of Armillariella mella(Vahl.ex Fr.) karst., Armillariella tabescens(Scop.) Sing., Lepista nuda(Bull.ex Fr.) Cooke and Lepista sordida(Schum.ex Fr.) Sing., Hygrophorus russula (Schaeff.ex Fr.) Qu'el., Hygrocybe conica(Scop.ex Fr.) Kummur were incinerated and analyzed by an atom adsorption spectrophotometry. The six mushrooms contained ubiquitously potassium, iron, zinc, sodium, manganase, copper and calsium in that order, and the content of potassium was the highest than other inorganic components and the content of zinc in Hygrocybe conica was especially the most than the other five mushrooms. Total contents of inorganic components(except Cd) were universally the highest in Hygrocybe conica than other five mushrooms, and decrease in order Hygrophorus russula, lepista nuda, lepista sordida, Aarmillariella mella and Armillariella tabescens. Calsium was not present in Amillariella mella and lepista nuda, and copper not in Hygro­cybe conica, and content of cadimium in Hygrophorus russula and Hygrocybe conica were trace.

  • Apoptosis, programmed cell death pathway, is a vital physiological mechanism that ensures cellular homeostasis and overall cellular well-being. In the context of cancer, where evasion of apoptosis is a hallmark, the overexpression of anti-apoptotic proteins like Bcl2, Bcl-xL and Mcl-1 has been documented. Consequently, these proteins have emerged as promising targets for therapeutic interventions. The BCL-2 protein family is central to apoptosis and plays a significant importance in determining cellular fate serving as a critical determinant in this biological process. This review offers a comprehensive exploration of the BCL-2 protein family, emphasizing its dual nature. Specifically, certain members of this family promote cell survival (known as anti-apoptotic proteins), while others are involved in facilitating cell death (referred to as pro-apoptotic and BH3-only proteins). The potential of directly targeting these proteins is examined, particularly due to their involvement in conferring resistance to traditional cancer therapies. The effectiveness of such targeting strategies is also discussed, considering the tumor's propensity for anti-apoptotic pathways. Furthermore, the review highlights emerging research on combination therapies, where BCL-2 inhibitors are used synergistically with other treatments to enhance therapeutic outcomes. By understanding and manipulating the BCL-2 family and its associated pathways, we open doors to innovative and more effective cancer treatments, offering hope for resistant and aggressive cases.
