  • Objective: The study was conducted to assess biochemical profiles in premenopausal and postmenopausal women having breast cancer. Materials and Methods: A hospital based case control study was carried out at Manipal Teaching Hospital (MTH), Pokhara, Nepal. The analysed variables were age, metabolic profile including total cholesterol, triglycerides, HDL-C, LDL-C, blood sugar, insulin concentration, C-peptide, HbA1c and selenium. Descriptive statistics and testing of hypothesis were used for the analysis using EPI INFO and SPSS 16 software. Results: In premenopausal women, significant differences were noted for total cholesterol (P value <0.001), triglycerides (P value 0.002), HbA1c level (P value <0.001), insulin concentration (P value 0.030), C-peptide concentration (P value 0.001), and selenium (P value <0.001) between cases and controls. Insignificant results were found for HDL-C (P value 0.749), LDL-C (P value 0.933), blood sugar (P value 0.59) and BMI (P value 0.746). Similarly, significant difference in total cholesterol (P value <0.001), triglycerides (P value 0.001), LDL-C (P value <0.001), HDL-C (P value 0.025), blood sugar (P value <0.001), insulin concentration (P value <0.001), c-peptide concentration (P value <0.001), HbA1c level (P value <0.001) and selenium (P value <0.001) were observed for postmenopausal patients and controls. Conclusions: Assessing metabolic changes and their management may be important for control of breast cancer and increased survival.

  • The authors studied the viability and pH of Lactobacillus casei which was isolated from the Yakult in terms of its storage temperature time(days). The following results have been obtained: (1) The viability test to Lactobacillus casei under storage in 4$\circ$C temperature condition in 35 days, has shown that the original population of $4.0\times 10^8$ organisms was decreased to $0.1\times 10^8$, under storage in 10$\circ$C temperature the organisms to $0.08\times 10^8$, in room temperature the organisms to $0.009\times 10^8$, and in 35$\circ$C temperature the organisms to $0.0009\times 10^8$. The correlation coefficient of storage period (days) and number of bacterial viability were significant as r=0.956(p<0.01) in 4$\circ$C, r=-0.999 (p<0.01) in 100C, r=0.975(p<0.01) in room temperature and r=-0.923(p<0.01) in 35$\circ$C. (2) The pH test to Lactobacillus casei unde.r storage in 4$\circ$C temperature condition for 35 days has shown that the original pH of 3.54 were acidified to 3.35, under storage in 10$\circ$C temperature the pH were acidified to 3.20, in room temperature the pH were acidified to 3.15, and in 35$\circ$C temperature the pH were acidified to 3.0. The correlation coefficient of variation of pH between storage period (days) and temperature were significant as r=-0.972(p<0.01) in 4$\circ$C, r=-0.922 (p<0.01) in 10$\circ$C, r=-0.963 (p<0.01) in room temperature and r=-0.953 in 35$\circ$C.

  • In order to determin the optimum extraction condition for protein in a Chrysalis of Silk Worm, Temperature, Time, and pH variation were conducted in the extraction. N.S.I. and nitrogen contents of the extracts in this condition were identified by Kjeldaha method and a C.H.N. corder. The results were as follows; Crude protein and crude fat contents in the extracts were 23.34% and 15.61%, respectively. N.S.I. values with respect to the temperature variation were 6.7% at 6$0^{\circ}C$, 7.94% at 8$0^{\circ}C$ and 8.67% at 10$0^{\circ}C$ in the condition of pH 4, 1 hr. N.S.I. values in pH variation were 7.94% at pH4, 8.99% at pH6, 9.70% at pH8, 10.19% at pH 10 and 12.16% at pH 12 in the condition of 8$0^{\circ}C$, 1hr. N.S.I. values in extraction time variation were 8.67% in 1hr, 9.23% in 2hr and 9.76% in 3hr in the condition of 10$0^{\circ}C$, pH 4. The tendency of N.S.I. variation in this extration condition was reconfirmed also by a C.H.N. corder.

  • This paper introduces and studies a generalization of the classical Struve function of order p given by $$_aS_{p,c}(x):=\sum\limits_{k=0}^{\infty}\frac{(-c)^k}{{\Gamma}(ak+p+\frac{3}{2}){\Gamma}(k+\frac{3}{2})}(\frac{x}{2})^{2k+p+1}$$. Representation formulae are derived for $_aS_{p,c}$. Further the function $_aS_{p,c}$ is shown to be a solution of an (a + 1)-order differential equation. Monotonicity and log-convexity properties for the generalized Struve function $_aS_{p,c}$ are investigated, particulary for the case c = -1. As a consequence, $Tur{\acute{a}}n$-type inequalities are established. For a = 2 and c = -1, dominant and subordinant functions are obtained for the Struve function $_2S_{p,-1}$.

  • Background: The development of a vaccine for Jembrana disease is needed to prevent losses in Indonesia's Bali cattle industry. A DNA vaccine model (pEGFP-C1-tat) that requires a functional delivery system will be developed. Polylactic-co-glycolic acid (PLGA) may have potential as a delivery system for the vaccine model. Objectives: This study aims to evaluate the in vitro potential of PLGA as a delivery system for pEGFP-C1-tat. Methods: Consensus and codon optimization for the tat gene was completed using a bioinformatic method, and the product was inserted into a pEGFP-C1 vector. Cloning of the pEGFP-C1-tat was successfully performed, and polymerase chain reaction (PCR) and restriction analysis confirmed DNA isolation. PLGA-pEGFP-C1-tat solutions were prepared for encapsulated formulation testing, physicochemical characterization, stability testing with DNase I, and cytotoxicity testing. The PLGA-pEGFP-C1-tat solutions were transfected in HeLa cells, and gene expression was observed by fluorescent microscopy and real-time PCR. Results: The successful acquisition of transformant bacteria was confirmed by PCR. The PLGA:DNA:polyvinyl alcohol ratio formulation with optimal encapsulation was 4%:0.5%:2%, physicochemical characterization of PLGA revealed a polydispersity index value of 0.246, a particle size of 925 nm, and a zeta potential value of -2.31 mV. PLGA succeeded in protecting pEGFP-C1-tat from enzymatic degradation, and the percentage viability from the cytotoxicity test of PLGA-pEGFP-C1-tat was 98.03%. The PLGA-pEGFP-C1-tat demonstrated luminescence of the EGFP-tat fusion protein and mRNA transcription was detected. Conclusions: PLGA has good potential as a delivery system for pEGFP-C1-tat.

  • In this paper, a boundary version of the Schwarz lemma is investigated. We take into consideration a function $f(z)=z+c_{p+1}z^{p+1}+c_{p+2}z^{p+2}+{\cdots}$ holomorphic in the unit disc and $\|\frac{f(z)}{{\lambda}f(z)+(1-{\lambda})z}-{\alpha}\|$ < ${\alpha}$ for ${\mid}z{\mid}$ < 1, where $\frac{1}{2}$ < ${\alpha}$ ${\leq}{\frac{1}{1+{\lambda}}}$, $0{\leq}{\lambda}$ < 1. If we know the second and the third coefficient in the expansion of the function $f(z)=z+c_{p+1}z^{p+1}+c_{p+2}z^{p+2}+{\cdots}$, then we can obtain more general results on the angular derivatives of certain holomorphic function on the unit disc at boundary by taking into account $c_{p+1}$, $c_{p+2}$ and zeros of f(z) - z. We obtain a sharp lower bound of ${\mid}f^{\prime}(b){\mid}$ at the point b, where ${\mid}b{\mid}=1$.

  • C11, a chloride-containing VK3 analog, acts as a mediator of programmed cell death in SK-Hep-1 cell lines, but its molecular mechanisms linked to cell death are not understood. In this study, we investigated the expression of p21 gene and its relationship to apoptosis induced by C11. In SK -hep-1 cells, the addition of C11 resulted in time-dependent growth suppression and DNA fragmentation characteristics of apoptosis. p21 protein was induced during this process, while the protein level of p53 was not changed at the same condition. This apoptotic cell death with p21 induction was also observed in the Hep3B cells lacking functional p53 after treatment of C11. These results suggest that C11-induced apoptosis is associated with up-regulation of p21 protein in p53-independent pathway. Next, in order to confirm whether the p53-independent p21 induction is required for C11-induced apoptosis, we introduced the p21 gene into Hep3B. Overexpression of p21 did not affect the expression of the bcl-2 gene, but DNA fragmentation and PARa cleavage were significantly increased. These data indicate that p21 is involved in C11-induced apoptosis. Although Bcl-2 has been implicated to interfere with an essential signaling molecule involved in the apoptosis pathway, its molecular mechanism and target molecule are poorly understood. To determine the effects of bcl-2 overexpression on apoptosis and to investigate whether BcI-2 interfers with the p53-independent p21 pathway, we transfected the bcl-2 expression vector into SK - Hep-1 cels. Overexpression of Bcl-2 prevented C11-induced apoptosis. Taken together, C11-induced apoptosis is regulated by p52-independent p21 pathway and bcl-2 may inhibit functional activity of p21, therebe may inhibit the C11-induced apoptosis.ptosis.

  • For 0 < $p$ < ${\infty}$, ${\alpha}$ > -1 and 0 < $r$ < 1, we show that if $f$ is in the space of Dirichlet type $\mathfrak{D}^p_{p-1}$, then ${\int}_{1}^{0}M_{p}^{p}(r,f^{\prime})(1-r)^{p-1}rdr$ < ${\infty}$ and ${\int}_{1}^{0}M_{(2+{\alpha})p}^{(2+{\alpha})p}(r,f^{\prime})(1-r)^{(2+{\alpha})p+{\alpha}}rdr$ < ${\infty}$ where $M_p(r,f)=\[\frac{1}{2{\pi}}{\int}_{0}^{2{\pi}}{\mid}f(re^{it}){\mid}^pdt\]^{1/p}$. For 1 < $p$ < $q$ < ${\infty}$ and ${\alpha}+1$ < $p$, we show that if there exists some positive constant $c$ such that ${\parallel}f{\parallel}_{L^{q(d{\mu})}}{\leq}c{\parallel}f{\parallel}_{\mathfrak{D}^p_{\alpha}}$ for all $f{\in}\mathfrak{D}^p_{\alpha}$, then ${\parallel}f{\parallel}_{L^{q(d{\mu})}}{\leq}c{\parallel}f{\parallel}_{\mathcal{B}_p(q)}$ where $\mathcal{B}_p(q)$ is the weighted Besov space. We also find the condition of measure ${\mu}$ such that ${\sup}_{a{\in}D}{\int}_D(k_a(z)(1-{\mid}a{\mid}^2)^{(p-a-1)})^{q/p}d{\mu}(z)$ < ${\infty}$.

  • An in vitro study was conducted to examine the effect of addition level of carbohydrates on fermentation characteristics, and bio-hydrogenation of unsaturated fatty acids by mixed rumen bacteria when incubated with soybean oil or flaxseed oil. Four levels(0%, 0.3%, 0.6% and 0.9%, w/v) of the mixed carbohydrates(glucose, cellobiose, soluble starch, 1:1:1, in weight basis) and oil sources(soybean or flaxseed oil, 60mg in 150ml culture solution) were added to the mixed solution of strained rumen fluid with artificial saliva(1:4, v/v), and incubated anaerobically for 12 hours at 39℃. pH and ammonia-N concentration were lower by increasing the substrate levels at all incubation periods(P<0.05~P<0.001). The propionate proportion increased(P<0.001), but acetic acid and butyric acid decreased(P<0.001) with the substrate level at 6 and 12 h incubations. Oil sources did not influence the proportions of individual VFA. At the end of incubation, the proportions of C18:0(P<0.01), C18:1(P<0.001) and trans-11C-18:1(P<0.01) were reduced but those of C18:2(P<0.001) and C18:3(P<0.01) were enhanced by the addition of flaxseed oil compared to addition of soybean oil. The proportions of C18:0 and total CLA were reduced(P<0.01) but those of trans-11-C18: (P<0.05) and C18:2(P<0.01) were increased with the substrate level when incubated with soybean oil or flaxseed oil. There were interactions(P<0.05) in the proportions of C18:1, C18:2 and C18:3(P<0.01) between oil source and substrate level. The proportions of cis-9, trans-11-CLA and trans-10, cis-12-CLA tended to reduce with substrate level, although there was no significant difference between treatments.

  • Comparison on the genomic structure and phylogenetic relationship of the Hsp88 genes from P. tenuipes Jochoen-1, P. tenuipes, C. militaris and C. pruinosa was described. The Hsp88 genes from the three entomopathogenic strains, P. tenuipes Jocheon-1(strain), P. tenuipes(original species), and C. militaris contain the identical genomic structure, namely 5 introns and 6 exons with the length of 13, 62, 32, 1,438, 306, 288 nucleotides encoding 713 amino acid residues, whereas in case of C. pruinosa, it contains 4 introns and 5 exons with the length of 13, 62, 32, 1,744, 288 nucleotides encoding 713 amino acid residues. The genomic DNA length of the Hsp88 genes from P. tenuipes Jocheon-1 and P. tenuipes are both 2,600 nucleotides long in size. The Hsp88 genes from C. militaris and C. pruinosa are 2,582, 2,576 nucleotides long in size, respectively. Hsp88 genes of the P. tenuipes Jochoen-1, P. tenuipes, C. militaris and C. pruinosa also contain the conserved ATP-binding domain. Phylogenetic analysis of the Hsp genes of the four strains tested in this study showed that the fungal Hsp88 is divided into two separate clades, ascomycetes and deutromycete. Within the ascomycetes fungal clade, the P. tenuipes Jochoen-1 and P. tenuipes formed a subgroup, on the other hand, C. militaris and C. pruinosa formed another subgroup. Pair-wise comparison of P. tenuipes Jocheon-1 Hsp88 with those of P. tenuipes, C. militaris and C. pruinosa Hsp88s revealed significant identity in deduced amino acid sequence among these strains. The P. tenuipes Jocheon-1 Hsp88 showed 99% identity with the P. tenuipes, 97% identity with the C. militaris, and 98% identity with the C. pruinosa.
