Systematic Review of Literature for Smartphones Technology Acceptance Using Unified Theory of Acceptance and Use of Technology Model (UTAUT)

Systematic Review and Meta-analysis are techniques which attempt to associate the findings from similar studies and deliver quantitative summaries of the research literature [1]. The Systematic review of research literature identifies the common research methods, research design, sample size, parameters used, survey instruments, etc. used by the group of researchers. This study intends to fulfill this purpose in order to identify common research mythologies, dependent variables, sample sizes, moderators and mediators used in the field of analysing technology adoption based studies that utilizes the UTAUT2 model. This research collected over 59 published articles and conducted descriptive analytics. The results have revealed performance expectancy/perceived usefulness, trust and habit as the best predictors of consumer behavioural intentions towards the adoption of mobile application. Behavioural intention was the best predictor of use behaviour among the 57 articles selected. 274 was the mean sample size of research with 25 mean questionnaire items. SPSS and AMOS were the most common softwares used in all 57 studies, and 32 of those studies used UTAUT1 model while 14 researches incorporated the UTAUT2 model. There were also two promising predictors such as perceived risk on behavioural intention and habit on use behaviour.

Diagnosis and treatment of small cell carcinoma of prostate and a review of literature

Objective To investigate histological features, clinical presentation,treatment and prognosis of small cell carcinoma of prostate. Methods Clinical,pathological and follow-up data of two cases of small cell carcinoma of prostate were respectively analyzed,and trlated literature was reviewed. Results Two cases of small

CCNO mutation as a cause of primary ciliary dyskinesia:A case report

BACKGROUND Primary ciliary dyskinesia(PCD)is an uncommon and genetically diverse condition.According to reports,most patients had more than 50 visits before being diagnosed with PCD,and the age at diagnosis was mostly in preschool,with an average age of about(10.9±14.4)years old.CCNO is a pathogenic gene that regulates the cell cycle,and its mutation is linked to the uncommon human genetic disorder PCD.Although the prevalence of the CCNO mutation is regarded to be exceptionally low,new reports of this mutation have increased in comparison to prior ones.PCD patients with CCNO are rare,and the incidence rate is no more than 2%in whole PCD patients.CASE SUMMARY Here,we report a case of a young Chinese woman diagnosed with PCD,who was found to carry the CCNO gene by whole exon gene sequencing.In this case,a young non-smoking Chinese female exhibiting recurrent cough and sputum at birth.Chest computed tomography(CT)showed bronchiectasis with infection,and sinus CT showed chronic sinusitis.However,the patient had no visceral transposition and no history of infertility.Under electron microscope,it was found that cilia were short and reduced in number,and no power arm of cilia was observed.Whole exon sequencing analysis of the genome of the patient showed that the patient carried CCNO pathogenic gene,exon c.303C>A nonsense mutation and c.248_252dup frameshift mutation.Her clinical symptoms and CT images were improved after two months of treatment with aerosol inhalation and oral azithromycin.CONCLUSION The results showed that CCNO is an important cause of PCD.More mutant genes that may contribute to genetically diverse disorders like PCD have been discovered as sequencing technology has advanced.Furthermore,the increase of genetic information makes it easier to diagnose uncommon diseases in clinical practice.
