Antibiotic resistance continues to pose a threat to the human race as bacteria become more and more resistant to antibiotics. New multi‐drug resistant (MDR) strains of tuberculosis, methicillin‐resistant staphylococcus aureus (MRSA), and vancomycin resistant enterococci (VRE), amongst other bacteria, are causing expen…
The thermal expansion of pure and Ti-bearing fused silica was estimated using free energy minimization lattice dynamics calculations in the quasiharmonic approximation. While the calculations give the expected drop in the coefficient of thermal expansion in going from quartz to fused silica, the overall shape of the c…
We used a combination of pressure‐perturbation techniques to explore conformational rearrangements in cytochrome P450 3A4. Site‐directed incorporation of a FRET donor‐acceptor pair allowed us to discover an equilibrium between open and closed states revealed in pressure‐induced increase in the distance between fluorop…
We prepared BaTi1-xMnxO3samples (x = 0 and 0.05) by standard solid-state reaction at 700°C and 900°C in an Ar ambient to change oxidation number of Mn dopants. The fabricated samples were then studied structural characterization and electronic structures by means of X-ray diffraction and absorption, and Raman scatteri…
Pyroglutamate forms via the cyclization of glutamine residues in proteins including amyloid β‐peptides associated with Alzheimer’s disease and oconase, an anti‐cancer agent. To study the role pyroglutamate plays in these proteins, we propose expanding the E. coli genetic code to include pyroglutamate by reassigning th…
Ryanodine receptor (RyR) activity causes Ca 2+ sparks in cerebral arterial myocytes by activating adjacent Ca 2+ ‐activated K + (BK) channels, which can dilate arteries. Previous studies show ontogeny increases Ca 2+ sparks and long‐term hypoxia (LTH) increases BK channel activity. We hypothesized that BK channel acti…
S22‐Gda is a purified extract from mixture of Celosia argentea Linne , Allium sativum L. and Plantago asiatica . Many herbal extract mixtures have been known to have various biological activities including stimulation of immune response. However, the biological effects of S22‐Gda have not been addressed. In the presen…
In this study, differences of texture image and preference for men’s suit fabrics according to mechanical properties, hand and fabric information were investigated. 55 subjects evaluated texture image and preference of 12 kinds of wool blended fabrics. For statistical analysis, t-test and pearson correlation coefficie…
Many proteins are modular in that they contain a series of independently‐folded domains. Often, these sub‐domains have no affinity for each other in solution, but can maintain a stable supertertiary structure when connected by polypeptide linkers. Little is known about the ultraweak interactions that dictate the stabi…
Cutting fluid adalah komponen yang sangat penting pada proses pemesinan (metal-cutting operation), selain untuk memperpanjang umur pahat cutting fluid dalam beberapa kasus mampu menurunkan gaya potong dan memperhalus permukaan produk hasil pemesinan. Kondisi pemesinan yang digunakan pada penelitian ini adalah pemesina…
Goal: to investigate the role of myostatin (Mst) in adult skeletal muscle structure, function and physical performance. We generated the conditional Mst overexpressing transgenic (CMOT) mice in which Mst expression can be switched ON or OFF. Methods: We used mechanical overloading (MO) (bilateral synergist ablation of…
This study is part of the SBEVSL project, the purpose of which is to propose and confirm the function of uncharacterized protein structures, in the Protein Data Bank, by use of in silico and in vitro quantitative techniques. For over 3000 structures in the PDB, no function has been assigned. These structures were firs…
This paper describes the development of needle type probe that measures temperature and injects medicine for both diagnosis and treatment of musculoskeletal pain syndrome (MPS). The size of trigger points is from several micrometers to millimeter. Therefore, it is required to develop a medical device that is capable o…
Effect of 8 different carbon compounds on the growth of Hendersonula toruloidea Nattrass, that causes brown rot of fruits of Malus sylvestris Mill has been studied. Galactose was the best; maltose, glucose, sucrose also supported good growth. Growth was moderate with glycerol and lactose but poor with starch.

Radioactive materials are used widely in various applications, which in turn have resulted in its large scale availability to the various end users. Though in India, there is strict regulatory control on obtaining radioactive material and their use, there have been reported cases of radioactive material detected as st…
Cytochrome c (Cyt c) is an essential mediator of apoptosis when it is released from the mitochondria to the cytoplasm. This process normally takes place in response to DNA damage, but in many cancer cells (i.e., cancer stem cells) it is disabled due to various mechanisms. However, it has been demonstrated that the tar…
The problem of an infinite plate perforated with a square hole with rounded corners has been solved when a part of the boundary is under uniform pressure and the rest is stress free. The solution has been obtained in a closed form by using Muskhelishvili's methods involving Cauchy's integrals. As a particular case, th…
Nanocrystalline diamond(NCD) films on steel(SKH51) has been investigated using SiC interlayer film. SiC was deposited on SKH51 or Si wafer by RF magnetron sputter. NCD was deposited on SiC at 600oC for 0.5~4 h employing microwave plasma CVD. Film morphology was observed by FESEM and FIB. Film adherence was examined by…
An icon of 20th Century Physics, Albert Einstein in fact made many mistakes in his career but none more egregious than setting the Constant in E = MC ^2 at 2.99 x 10^8, instead of the correct setting of the Constant at 3.35 x 108 . During his entire career, Einstein attempted seven times to provide a full proof for th…
