Expression and Significance of TNF-α and NF-κB/p65 in Cutaneous Lichen Planus.

Purpose: The purpose of this study was to explore the expression of TNF-α and NF-κB/p65 in Lichen planus skin lesions and their correlation with the pathogenesis of Lichen planus.

Patients And Methods: The case group consisted of 30 individuals diagnosed with LP based on clinical and histopathologic examination. The control group consisted of 10 individuals from an Orthopedic Department with normal skin.

HIV care continuum among newly diagnosed student and non-student youths between 2012 and 2016 in Hangzhou, China.

Background: Youths are disproportionally affected by the human immunodeficiency virus (HIV) infection. We aimed to assess anti-retroviral therapy (ART) initiation and viral suppression rates among student and non-student youths in Hangzhou, China.

Methods: Data were taken from the Chinese HIV/acquired immune deficiency syndrome Comprehensive Response Information Management System.

Intracerebroventricularly-administered 1-methyl-4-phenylpyridinium ion and brain-derived neurotrophic factor affect catecholaminergic nerve terminals and neurogenesis in the hippocampus, striatum and substantia nigra.

Parkinson's disease is a progressive neurological disease characterized by the degeneration of dopaminergic neurons in the substantia nigra. A highly similar pattern of neurodegeneration can be induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) or 1-methyl-4-phenylpyridinium ion (MPP), which cause the death of dopaminergic neurons. Administration of MPTP or MPP results in Parkinson's disease-like symptoms in rodents.

[Effects of Temperature on the Preparation of Al/Zn3N2 Thin Films Using Magnetron Reactive Sputtering].

The effects of substrate temperature on the plasma active species were investigated by plasma optical emission spectroscopy. With increasing substrate temperature, the characteristic spectroscopy intensity of the first positive series of N2* (B(3)Πg-->A(3)Σu(+)), the second positive N2* (C(3)Πu-->B(3)Πg), the first negative series N2(+)* (B(2)Σu(+)-->X(2)Σg(+)) and Zn* are increased. Due to the substrate temperature, each ion kinetic energy is increased and the collision ionization intensified in the chamber.

The neurotoxin 1-methyl-4-phenylpyridinium (MPP(+)) alters hippocampal excitatory synaptic transmission by modulation of the GABAergic system.

The neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induces Parkinson's disease-like symptoms following administration to mice, monkeys, and humans. A common view is that MPTP is metabolized to 1-methyl-4-phenylpyridinium ion (MPP(+)) to induce its neurodegenerative effects on dopaminergic neurons in the substantia nigra (SN). Moreover, the hippocampus contains dopaminergic fibers, which are projecting from the ventral tegmental area, SN and pars compacta and contain the whole machinery required for dopamine synthesis making them sensitive to MPTP and MPP(+).

[Optical emission analyses of N2/TMG ECR plasma for deposition of GaN film].

The optical emission spectroscopy of hybrid N2/trimethylgallium (TMG) plasma in an ECR-PECVD system was investigated. The results indicate that the TMG gas is strongly dissociated into Ga*, CH and H even under self-heating condition. Ga species and nitrogen molecule in metastable state are dominant in hybrid ECR plasma.

[Analysis of optical emission spectra from ICP of Ar in the vicinity of plasma sheath].

In order to control the ion density and energy distribution in the vicinity of plasma sheath independently, the inductively coupled plasma and its glow discharge mechanism in the vicinity of plasma sheath were studied by means of optical emission spectroscopy (OES) under different RF power, different discharge and different substrate DC bias voltage. It was shown that the ion density is higher and the electron temperature is lower in the vicinity of inductively coupled plasma sheath according to the ionic line and atomic line. With changing the discharge pressure and RF power, the spectral characteristics analysis shows that the ion density in the vicinity of plasma sheath linearly increases with the RF power and rises with the pressure under the low pressure.

[Isolation, characterization and expression analysis of male sterility gene homology sequence in wheat].

One 134 bp fragment was amplified in anthers of male sterile and fertile wheat using one pair of degenerated primer designed based on the conserved domain of MS2 gene in Arabidopsis thaliana and Oryza sativa, and one 1604 bp male sterility gene homology sequence was extended by in silico cloning based on the 134 bp fragment. The amino acids encoded by the male sterility gene homology sequence include a 200 amino acid conserved domain of male sterility, and this sequence expressed only in wheat male fertile anthers; no expression in male sterile anthers, roots and leaves. This research demonstrated that the cloned male sterile homology sequence is specific to wheat anther development.
