Assessing Communication Apprehension Among In-Service Teachers in A University of Education

This study examined Communication Apprehension among in-service teachers in a university of education in Nigeria with particular focus on the influence of gender and age on CA among the sample.  A cross-sectional ex post facto survey design was adopted for the study. Participants were 100 purposively & randomly sampled, in-service teachers drawn from a university of education in Nigeria. There were 35 (35%) males and 65 (65%) females, their ages ranged between 16 – 30 years with a mean age of 22.10 and a standard deviation of 2.48. of these samples, 71 were Christian, 27 Muslims and 2 belong to other religions. 90 of the total sample were singles, while 10 were married. Validated scale was used for data collection and three hypotheses tested using descriptive statistics and t-test for independent samples. Results showed that in-service teachers were not significantly high on CA and gender as well as age was not found to be significant predictors of CA among this sample. This result may be owing to the fact that they were purposive samples who have been exposed to pedagogical training that must have helped them to handle CA. it was recommended that further studies should examine other factors such as psychological and social and increase the sample size as well, cutting across other institutions apart from specialized university.

Relationship between Fecal Content of Fatty Acids and Cyclooxygenase mRNA Expression and Fatty Acid Composition in Duodenal Biopsies, Serum Lipoproteins, and Dietary Fat in Colectomized Familial Adenomatous Polyposis Patients

A few familial adenomatous polyposis studies have focused upon faecal sterols and bile acids but none has analysed the fecal content of fatty acids. We report here findings of an observational study on 29 colectomized familial adenomatous polyposis patients that describe the fecal content of fatty acids, and relate this to the proportions of fatty acids and levels of cyclooxygenase mRNA expression in duodenal biopsies, levels of serum lipoproteins, and diet. In the ileostomy group separately (n = 12), the fecal content of arachidonic acid was correlated negatively to the proportions of eicosapentaenoic acid and docosahexaenoic acid in duodenal biopsies. Total serum-cholesterol was negatively correlated to the fecal content of saturates and monounsaturates. The fecal palmitoleic acid/palmitic acid ratio was positively correlated to the levels of cyclooxygease-2 expression in duodenal biopsies.In the ileal-pouch-anal anastomosis group separately (n = 17), significant correlations were found between the fecal contents of oleic acid, linoleic acid, and alpha-linolenic acid, and the proportions of myristic acid, oleic acid and eicosaenoic acid in duodenal biopsies. Dietary monounsaturates were positively correlated to different fecal fatty acids. Future studies should focus on molecular mechanisms relevant to fatty acid metabolism, inflammation, and angiogenesis, in addition to nutrition

The Role of Bile in the Regulation of Exocrine Pancreatic Secretion

As early as 1926 Mellanby (1) was able to show that introduction of bile into the duodenum of anesthetized cats produces a copious flow of pancreatic juice. In conscious dogs, Ivy & Lueth (2) reported, bile is only a weak stimulant of pancreatic secretion. Diversion of bile from the duodenum, however, did not influence pancreatic volume secretion stimulated by a meal (3,4). Moreover, Thomas & Crider (5) observed that bile not only failed to stimulate the secretion of pancreatic juice but also abolished the pancreatic response to intraduodenally administered peptone or soap
