Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Prevalence of Agamid adenoviruses of the bearded dragons (Pogona vitticeps) in Japan

In this study, we surveyed the prevalence and characteristics of agamid adenovirus (genus Atadenovirus) infections in bearded dragons (Pogona vitticeps) in Japan. Swab samples were collected from the oral cavity and pharynx of 44 healthy bearded dragons and 24 bearded dragons with clinical signs of respiratory disease. PCR confirmed agamid adenovirus in 25 of the 44 healthy lizards (56.8%). Of the 24 bearded dragons with respiratory clinical signs, 14 were agamid adenovirus-positive (58.3%). Sex was determined for 21 of the 24 bearded dragons with respiratory clinical signs (9 males and 12 females). Agamid adenovirus was confirmed in two of the nine males (22.2%) and 10 of the 12 females (83.3%), indicating a higher prevalence of adenovirus in the females. Overall, the prevalence of agamid adenovirus in bearded dragons with respiratory clinical signs was almost the same as that in clinically healthy bearded dragons, suggesting that the virus is widespread in this species. In addition, we detected no apparent seasonality in the occurrence of agamid adenovirus infection. The mean value of globulin was slightly higher in seven of the female lizards with confirmed agamid adenovirus

Association between comprehensive workstation and neck and upper-limb pain among office worker

Objectives: Our study aimed to investigate the association between comprehensive workstations and neck and upper-limb pain (NUP) among office workers. Methods: This cross-sectional study included 307 office workers (median age, 39 years; 88% men). Workstations (presence of armrest, armrest position, number of monitors used, mouse position, mouse usage, keyboard usage, and keyboard position) were investigated in terms of 17 items and judged as "adequate" or "inadequate." NUP was assessed using a numerical rating scale. NUP locations included the neck, shoulder, elbow, and wrist. In the statistical analysis, outcome variables were the presence of pain in each part, while explanatory variables were the number of inadequate workstations. Logistic regression analyses were conducted with adjustment for age, gender, working duration, and exercise habit. Results: The prevalence of neck pain was 47% (n = 143), shoulder pain was 50% (n = 153), elbow pain was 7.2% (n = 22), and wrist pain was 13% (n = 40). In the adjusted model, the number of inadequate workstations had significant positive associations with elbow pain (odds ratio [OR], 1.39; 95% confidence interval [CI], 1.06.1.81) and wrist pain (OR, 1.80; 95% CI, 1.17.2.26). However, the number of inadequate workstations was not significantly associated with neck pain or shoulder pain. Conclusions: Workstation-related factors (presence of armrest, armrest position, mouse usage, and keyboard usage) were significantly associated with elbow and wrist pain. Our findings suggest that workstations can contribute to elbow and wrist pain in office workers

Effect of Pain Severity on Executive Function Decline in Community-Dwelling Older Adults

Objective: The purpose of this study was to explore the reciprocal relationship between pain severity and executive function in community-dwelling older adults. Method: In this prospective cohort study, 64 Japanese community-dwelling older adults aged 60 years or older (mean age 72.8 years; women, 68.8%) were analyzed. Pain severity was assessed by self-reported questionnaire while executive function was assessed by the Trail Making Test at baseline and at 1-year follow-up assessment. A mixed effect model was conducted to analyze the effect of baseline executive function on change in pain severity and effect of baseline pain severity on change in executive function. Results: The effect of baseline Trail Making Test on change in pain severity was not significant. On the contrary, the effect of high baseline pain severity on the decline in set shifting (Trail Making Test Part B) was significant even after adjustment with age, sex, years of education, depressive symptoms, and analgesic drug use. Conclusion: Higher baseline pain severity was associated with greater executive function decline in community-dwelling older adults. Executive function decline due to severe pain should be considered as well as pain itself
