DPP4 rapidly deactivates hormones and cytokines by cleaving their NH2-terminal dipeptides. Its functions are based on membrane digestion and/or binding of bioactive peptides, signal molecules, and extracellular matrix components. The soluble form is also present in body fluids such as serum, urine, semen, and synovial fluid. The extremely broad distribution of CD26/DPP4 indicates its divergent roles depending on cell type and activated conditions. The cellular localization was earlier examined by enzyme histochemistry and subsequently by immunohistochemistry. Although immunohistochemical analyses are higher in specificity and easier to use at electron microscopic levels than enzyme histochemistry, the immunoreaction is considerably affected by the animal species, types of tissue sections, and specificity of antibodies. Understanding of the functional significance and advancement of its clinical use (diagnosis and treatment of diseases) require precise information on the cellular distribution including subcellular localization and pathological changes. This short review summarizes in particular immunohistochemical findings on CD26/DPP4.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":"42 6","pages":"229-237"},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39749586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These rib variants represent disturbances of early organogenesis and are associated with stillbirths, childhood cancers, and several other congenital malformations. The present study aims to document the current prevalence, gender preferences, and laterality associations of various costal anomalies at the thoracic outlet in the reference population. A retrospective cross-sectional analytical study was conducted on 1474 PA skiagrams of the cervico-thoracic region, which comprised 919 males and 555 females of zero days to 73-year age. In 13.02% population, costal element exhibited anomalous development. Anomalies of the costal process of C7 vertebra showed higher(12.20%) prevalence compared to the thoracic first(0.81%). Elongation of the cervical 7 transverse process was most common(10.71%) followed by cervical rib(1.49%), rudimentary first rib (0.54%), and fusion of first and second ribs(0.27%). Cervical 7 costal anomalies showed a significant inclination towards females. No significant association with laterality and sidedness was observed for any of the anomalies. The study highlights a higher prevalence of an elongated transverse process of C7 compared to cervical rib and first rib anomalies in the reference population.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":"35 1","pages":"7-14"},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78121977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, World Health Organization (WHO) reported that these numbers are predicted to increase to 80 million by the year 2030. Vitamin D regulates glucose metabolism and oxidative stress is a well-established factor of this multi-factorial disease. Aim: Present, study was designed to evaluate certain oxidative stress markers like malondialdehyde, superoxide dismutase, reduced glutathione, glutathione reductase, Glutathione Peroxidase (GPx) along with total antioxidant activity in vitamin D deficient newly diagnosed Type 2 diabetics. Methods: 150 vitamin D deficient newly diagnosed type 2 diabetics’ and equal number of healthy subjects of both genders were recruited. Fasting blood was collected for evaluation of glucose, 25(OH) D and oxidative stress markers. Results: Significant (P<0.01) increase in malondialdehyde by 51.03% while a significant decrease in oxidative stress markers like SOD, GSH, GR, GPx and total antioxidant activity by 27.91 (P<0.05), 26.14% (P<0.05), 32.04% (P<0.01), 25.41% (P<0.05) and 35.85% (P<0.01) respectively was recorded in vitamin D deficient newly diagnosed type 2 diabetics with respect to healthy controls. Conclusions: A fore mentioned observations suggested that vitamin-D deficient newly diagnosed Type-2 diabetics of North-West Indian’s are associated with oxidative stress, a hallmark of various diseases like Diabetes Mellitus, cardiovascular diseases, osteoporosis etc. Therapeutic interventions in combinations of lifestyle and dietary modification might be beneficial to prevent further risk of development of Diabetes Mellitus and cardiovascular diseases like atherosclerosis in North-West Indians.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":"37 1","pages":"1-6"},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79910112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This hereditary cancer is caused by germline variants in MEN1. Two patients with MEN1 were identified via whole exome sequencing and gene expression profile analysis, conducted for 5,063 patients with various types of cancers. We obtained multiple tumors from each patient; tumors derived from these two MEN1 patients had a loss of the normal MEN1 allele and frequently chromosomal copy number changes. Thus, we investigated whether structural variants were present in the MEN1 patient genomes. Whole-genome sequencing revealed no catastrophic rearrangements, and the tumor samples had very low somatic variants. The two patients had germline variants in MEN1 and some chromosomal copy number changes including on chromosome 11. The only pathogenic variant detected was the MEN1 germline variant, and chromosomal rearrangements led to tumorigenesis in somatic cells. Furthermore, the MEN1 tumor samples displayed a specific signature characterized by T:A>C:G transition. Studies of multiple tumors obtained from single patients are rare in hereditary cancer syndromes, and our results provide insights that the second hit of the tumor suppressor gene MEN1 may be caused by a gross genome rearrangement, not a small insertion and deletion, nor a change in epigenetic regulation.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":"42 2","pages":"89-94"},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25589574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The executive functions are processes related to the planning of the behaviour oriented to the achievement of a goal. A cross-sectional study was carried out, with a sample of 48 participants; 18 with vascular headache, 14 with tension headache, 16 with migraine. Significant differences have been found in the capacity for abstraction, which has discriminated between patients with vascular headache and tension headache, as well as between these and patients with migraine. Similarly, overall cognitive performance is different in patients with migraine compared with patients with vascular headache and tension headache. The type of headache and global cognitive impairment moderately affect the variability of abstraction capacity. Finally, the existence of a directly proportional relation of positive nature that indicates a dependent between the variables has been evidenced. It can be concluded that global cognitive deterioration affects the performance of abstraction capacity.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":"6 1","pages":"10-16"},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88141313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Main outcomes were a compiled neurological or neurodevelopmental outcome; any developmental delay; motor developmental delay; and cognitive developmental delay. For analysis, the study population was divided into two groups: one group consisted of children who suffered from 5 or more episodes of hypoglycemia in neonatal period (n=42) and the second group consisted those who suffered with less than 5 episodes (n=128). We noted that the group having 5 or more hypoglycemic episodes had a higher proportion of premature or small for date children than the other group (76.2% Vs 60.9%), and the difference is statistically significant. In adjusted regression analyses, the odds ratio (OR) of any neurological or neurodevelopmental outcome was 1.48 (95% confidence interval: 1.17–1.88) in group with 5 or more hypoglycemic episodes as compared to the other group. The adjusted risk of any developmental delay was more than doubled (OR 2.53 [1.71–3.73]), the adjusted risk of motor developmental delay was almost doubled (OR: 1.91 [1.06–3.44]) and the adjusted risk of cognitive developmental delay was almost tripled (OR 2.85 [1.70–4.76]) in the group that had more than 5 hypoglycemic episodes in neonatal period.","PeriodicalId":9138,"journal":{"name":"Biomedical Research-tokyo","volume":"44 1","pages":"32-36"},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79804435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
