  • The aim of the study was to investigate the effects of 904 nm GaAs laser irradiation for patients with hypersensitive teeth and to find the possibility of clinical use of this Low Level Laser Therapy (LLLT) for the control of hypersensitive teeth. Eleven patients visited Dept. of Oral Medicine, Dankook University participated in this study. Each patient contributed at least two or more contralateral pairs of hypersensitive teeth with exposed dentine at cervical surfaces. Total number of teeth used from subjects participated in this study was 50: 25 experimental and control teeth respectively. All participants were treated with 904 nm GaAs diode laser every week during 4 weeks. Tactile and cold (ice stick) tests were carried out before LLLT every week during 4 weeks and 1 week later after the last LLLT by measuring visual analogue scale (VAS) of patients and by measuring a score of electrical pulp tester (EPT) simultaneously. The VAS score in tactile test decreased significantly with time, but there was not statistically difference between those of groups. The score of EPT in the experimental group was significantly higher than that of control group, although there was no change with time. In cold test, there was significant difference between two groups and cold sensitivity of the experimental group significantly decreased with time after every LLL irradiation, compared with that of control group. Based on the results, it is suggested that the 904 nm GaAs laser irradiation could be positively used as an effective, reversible method in treating cervical dentine hypersensitivity.

  • The purpose of this study was to detect early children with hyperactivity which is one of the symptoms of Attention Deficit - Hyperactivity Disorder (:ADHD). For this Purpose, This study used two methods; K-CBCL and observation of children`s behavior. K-CBCL was done online by parents at home. For observation of children's behavior, the school asked children to wear a 3 - axis accelerometer on their wrists. The data from K - CBCL and 3 - axis accelerometer were analyzed and clustered to separate hypersensitive children from ordinary children.

  • In response to fungal invasion and other signals, plants accumulate a number of proteins that are involved in defense against pathogens. Osmotin is a 24 kDa protein belonging to the pathogenesis-related (PR) protein, a component of the hypersensitive response in leaves of tobacco plants exposed to tobacco mosaic virus.(omitted)

  • Amino acid sequence alignment shows that $\underline{P}$roteus $\underline{m}$irabilis $\underline{t}$ranscription $\underline{r}$egulator (PMTR) has cystein sequence homology at metal binding domain to CueR (copper resistance) protein, which conserves two cysteins (Cys 112 and Cys 120 in PMTR). Gel shift assay revealed that PMTR protein bound to promoter region of Escherichia coli copA (copper-translocating P-type ATPase) and Proteus mirabilis atpase (putative copper-translocating P-type ATPase) genes except that of E. coli zntA (zinc-translocating P-type ATPase) gene. DNase I protection experiment indicated that PMTR protein protected the region over -35 box and close to -10 box. DNase I hypersensitive bases were shown at C and A bases of labeled template strand and at G and C bases of labeled non-template strand of DNA. These hypersensitive bases were appeared in other metalloregulatory proteins of MerR family, which suggests protein-induced DNA bending.

  • A useful receptor for the sensing of ${CIO_4}^-$ species with remarkable selectivity has been developed. The hypersensitive interaction between a host and a guest has been investigated for the complex $[Pd(Me_4en)(Py_2S){\cdot}2ClO_4]_4$ ($Me_4en$ = N,N,N',N'-tetramethylethylenediamine; $Py_2S$ = 4,4'-dipyridyl sulfide). The pyridyl moiety of $Py_2S$ exhibits two sets of $^1H$ resonances that are delicately dependent upon temperature, concentration, and media. The nonrigidity has been explained in terms of an electrostatic equilibrium between the tetrameric host and the ${CIO_4}^-$ guest. The equilibrium is a useful method for the detection of ${CIO_4}^-$ anion with remarkable selectivity via "a restricted guest within a big host" in aqueous solution.

  • $HpaG_{Xooc}$, from rice pathogenic bacterium Xanthomonas oryzae pv. oryzicola, is a member of the harpin group of proteins, eliciting hypersensitive cell death in non-host plants, inducing disease and insect resistance in plants, and enhancing plant growth. To express and secret the $HpaG_{Xooc}$ protein in Bacillus subtilis, we constructed a recombinant expression vector pM43HF with stronger promoter P43 and signal peptide element nprB. The SDS-PAGE and Western blot analysis demonstrated the expression of the protein $HpaG_{Xooc}$ in B. subtilis. The ELISA analysis determined the optimum condition for $HpaG_{Xooc}$ expression in B. subtilis WBHF. The biological function analysis indicated that the protein $HpaG_{Xooc}$ from B. subtilis WBHF elicits hypersensitive response(HR) and enhances the growth of tobacco. The results of RT-PCR analysis revealed that $HpaG_{Xooc}$ induces expression of the pathogenesis-related genes PR-1a and PR-1b in plant defense response.

  • PI201232, a pepper line resistant to Phytophthora capsici Leonian, was crossed with PI2713222 and P1163192, resistant to Xanthomonas campestTis pv. vesicatoria (Doidge) Dye and inheritance of the resistance to each disease and genetic relationship between the two disease resistances was studied. Non-hypersensitive resistance to race 3 of X. c. pv. vesicatoria of PI271322 was inherited in a quantitative mode. Resitance to P. capsici of PI201232 was inherited in a mode close to two dominant alleles. Hypersensitive resistance to race 1 of X. c. pv. vesicatoria of PI271322 was inherited in a mode of single dominant allele. PI 163192 was consistently resistant to both race 1 and race 3 of X c. pv. vesicatoria and the resistance was inherited in a quantitative mode with high dominance effect. Resistance to X. c. pv. vesicatoria was inherited independently from resistance to P. capsici.
