RegIV expression showing specificity to gastrointestinal tract and its potential role in diagnosing digestive tract neuroendocrine tumor

Regenerating gene IV (RegIV),a member of the regenerating gene family discovered in 2001,has been found to be involved in malignancy in several different organs including the stomach,colorectum,pancreas and prostate,but the overall expression profile of RegIV has not been reported. To learn more about RegIV,we evaluated its distribution by immunohistochemistry (IHC) in a total of 360 samples including 24 types of normal tissue,40 benign and malignant lesions,and 18 neuroendocrine tumors. We found that in no...     

Intramammary expression and therapeutic effect of a human lysozyme-expressing vector for treating bovine mastitis

To develop a gene therapy strategy for treating bovine mastitis, a new mammary-specific vector containing human lysozyme （hLYZ） cDNA and kanamycin resistance gene was constructed for intramammary expression and clinical studies. After one time acupuncture or intracisternal infusion of healthy cows with 400μg of the p215C3LYZ vector, over 2.0 μg/ml ofrhLYZ could be detected by enzymatic assay for about 3 weeks in the milk samples. Western blotting showed that rhLYZ secreted into milk samples from the vector-injected cows had molecular weight similar to that of the natural hLYZ in human colostrums. Twenty days after the primary injection, the quarters were re-injected with the same vector by quarter acupuncture and even higher concentrations of rhL YZ could be detected. Indirect competitive ELISA of milk samples showed that the vector injection did not induce detectable humoral immune response against hL YZ. Clinical studies showed that twice acupuncture of quarters with the p215C3LYZ vector had overt therapeutic effect on clinical and subclinical mastitis previously treated with antibiotics, including disappearance of clinical symptoms and relatively high microbiological cure rates. These data provide a solid rationale for using the vector to develop gene therapy for treating bovine mastitis.     

谈苏轼词的“多情”

词的特点是长于抒情.苏轼词之所以受到人们喜爱,在于他掌握了词的创作规律,在词中抒发了强烈的感情,从而引起读者共鸣.苏轼是一个多情的词人.他热情澎湃,激情四溢,豪情万丈.所以他的词具有无与伦比的感染力,如火如荼的煽情性.苏轼词中表达了豪情、韧情、亲情、爱情、艳情、真情、怡情、民情、同情、傲情、乡情等.故称苏轼为词中"情圣"乃是当之无愧的.     

论清乐抒情、娱乐功能之消长对乐府诗的影响

作为唐代清乐主流的清商曲辞,其比重不如相和、杂曲;作为唐代清商曲主流的三十二调,其歌辞比重也不如清商曲辞中的其他曲调.这两"少"说明衰落了的音乐在一定程度上对歌辞的创作具有抑制作用.娱乐性的歌辞表达的往往是一种泛化的情感,这并不利于作者情感的抒发.娱乐性的减弱使唐代诗人得以借乐府古题来抒发其强烈的感情.

The Influences of Brain Dominance and Biological Sex on Emotional Expressivity,Sensitivity, and Control

Nonverbal communication is the primary channel for the communication of emotion. The abilities to express, control, and decode emotions are important social skills. In this study, we investigated the effects of hemispheric brain dominance and sex on emotional social skills, specifically emotional expressivity, sensitivity, and control. Using the measurements of handedness, we classified participants as being standard, mixed, or anomalous dominant. We presumed that hemispheric brain dominance and sex would interact to influence emotional expressivity, sensitivity, and control. Analysis revealed that brain dominance and sex interacted to influence negative emotional expressivity and emotional control. Specifically, mixed dominant (MD) males scored highest in negative emotional expressivity and lowest in emotional control, whereas MD females scored lowest on negative emotional expressivity and second highest on emotional control. In general, MD men and women reported behaviors opposite of traditional sex differences in emotional expression.
