C Philipp E Nothaft
The article introduces a previously unknown fourteenth-century treatise on computus and calendrical astronomy entitled Expositio kalendarii novi, whose author proposed elaborate solutions to the technical flaws inherent in the calendar used by the Roman Church. An analysis of verbal parallels to other contemporary works on the same topic makes it possible to establish that the Expositio was produced in the context of a calendar reform initiative led by Pope Clement VI in 1344/45 and that this anonymous text is probably identical to a 'great and laborious work' on the calendar that the monk Johannes de Termis prepared for the pope around this time...

Family educational involvement and parent-teacher relationships are important for supporting student outcomes and have unique implications for families of children with autism spectrum disorder (ASD). However, little research has examined child and family characteristics among families of children with ASD as predictors of family involvement and parent-teacher relationships. The present study examined child and family variables that may affect family involvement and parent-teacher relationships for families of children with ASD...

Patient-reported outcome is increasingly applied in health sciences. Patients with eating disorders (EDs) characteristically have a different opinion of their needs to that of the health professionals, which can lead to ambivalence towards treatment and immense compliance difficulties. This cross-sectional study compared data assessed by the clinician to patient-reported measures in patients with a history of EDs. We included data from a cohort of patients with EDs (n=544) referred to a specialized ED unit in Denmark...

Food allergy is a common disorder especially in the first years of life. Strict avoidance of the responsible food is the most effective therapeutic measure so far. But this continuous vigilance could be stressful for the patient and family and decreases their quality of life (QOL). This survey was designed to evaluate the impact of IgE-mediated food allergy on parental QOL in Iranian patients and to develop a valid Persian version of "Food Allergy Quality Of Life- Parental Burden (FAQL-PB) questionnaire". 90 patients (28 females, 62 males) and their parents who were referred to the clinic of Allergy in Children's Medical Center, Tehran University of Medical Sciences, Tehran, Iran were enrolled...

There has been a strong demand in Japan and East Asia for L-glutamic acid as a seasoning since monosodium glutamate was found to present umami taste in 1907. The discovery of glutamate fermentation by Corynebacterium glutamicum in 1956 enabled abundant and low-cost production of the amino acid, creating a large market. The discovery also prompted researchers to develop fermentative production processes for other L-amino acids, such as lysine. Currently, the amino acid fermentation industry is so huge that more than 5 million metric tons of amino acids are manufactured annually all over the world, and this number continues to grow...

Synaptic plasticity is widely considered to be the neurobiological basis of learning and memory by neuroscientists and researchers in adjacent fields, though diverging opinions are increasingly being recognized. From the perspective of what we might call "classical cognitive science" it has always been understood that the mind/brain is to be considered a computational-representational system. Proponents of the information-processing approach to cognitive science have long been critical of connectionist or network approaches to (neuro-)cognitive architecture, pointing to the shortcomings of the associative psychology that underlies Hebbian learning as well as to the fact that synapses are practically unfit to implement symbols...

REVIEW
David S Moore, David Shenk
The term 'heritability,' as it is used today in human behavioral genetics, is one of the most misleading in the history of science. Contrary to popular belief, the measurable heritability of a trait does not tell us how 'genetically inheritable' that trait is. Further, it does not inform us about what causes a trait, the relative influence of genes in the development of a trait, or the relative influence of the environment in the development of a trait. Because we already know that genetic factors have significant influence on the development of all human traits, measures of heritability are of little value, except in very rare cases...

Bangladesh is one of the smaller states in Asia. But it has a long and rich history of nuclear medicine for over sixty years. The progress in science and technology is always challenging in a developing country. In 1958, work for the first Nuclear Medicine facility was commenced in Dhaka in a tin-shed known as 'Radioisotope Centre' and was officially inaugurated in 1962. Since the late 50s of the last century nuclear medicine in Bangladesh has significantly progressed through the years in its course of development, but still the facilities are inadequate...

Shortly after the isolation of Marek's disease (MD) herpesvirus (MDV) in the late 1960s vaccines were developed in England, the United States, and The Netherlands. Biggs and associates at the Houghton Poultry Research Station (HPRS) in England attenuated HPRS-16, the first cell-culture-isolated MDV strain, by passaging HPRS-16 in chick kidney cells. Although HPRS-16/Att was the first commercially available vaccine, it never became widely used and was soon replaced by the FC126 strain of herpesvirus of turkeys (HVT) vaccine developed by Witter and associates at the Regional Poultry Research Laboratory (now Avian Disease and Oncology Laboratory [ADOL]) in East Lansing, MI...

Importance: Cognitive impairment and dementia, including Alzheimer disease (AD), are common within the aging population, yet the factors that render the aging brain vulnerable to these processes are unknown. Perivascular localization of aquaporin-4 (AQP4) facilitates the clearance of interstitial solutes, including amyloid-β, through the brainwide network of perivascular pathways termed the glymphatic system, which may be compromised in the aging brain. Objectives: To determine whether alterations in AQP4 expression or loss of perivascular AQP4 localization are features of the aging human brain and to define their association with AD pathology...

BACKGROUND: Platelet dysfunction, including that caused by antiplatelet agents, increases the risk of perioperative bleeding. The optimal management of patients with platelet dysfunction undergoing surgery is unclear. OBJECTIVES: To assess whether desmopressin reduces perioperative allogeneic red cell transfusion and bleeding for patients with platelet dysfunction. PATIENTS/METHODS: We searched for randomised controlled trials in The Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, Embase, the Transfusion Evidence Library and ISI Web of Science to 7(th) July 2016...

Efforts to prevent melanoma, especially for those at elevated risk for the disease, should ideally begin during childhood. However, there are few preventive interventions targeting children who are at higher risk for melanoma due to a family history of the disease. Further, there are no educational interventions that aim to help these at-risk children understand their risk for melanoma and the ways in which preventive behaviors, such as sun protection, can mitigate their risk. The current paper describes a multidisciplinary team's process for creating a developmentally appropriate educational intervention about melanoma risk and prevention for children ages 8-17 years who have a family history of melanoma...

BACKGROUND: The diagnosis of asthma in children is challenging and relies on a combination of clinical factors and biomarkers including methacholine challenge, lung function, bronchodilator responsiveness, and presence of airway inflammation. No single test is diagnostic. We sought to identify a pattern of inflammatory biomarkers that was unique to asthma using a targeted metabolomics approach combined with data science methods. METHODS: We conducted a nested case-control study of 100 children living in a peri-urban community in Lima, Peru...

BACKGROUND: Infection with blood-borne viruses including hepatitis C (HCV) and hepatitis G (HGV) viruses is a substantial health problem. Varying prevalences of these infections in different studies reflect the role of predisposing risk factors in different countries or even different regions of a country. OBJECTIVES: The objective of the present survey was to assess the prevalences of HCV and HGV virus infections among hemodialysis (HD) patients in Bandar Abbas, Hormozgan, Iran, 2015...

Recent studies based on biography analysis provide support for the notion that the prevalence of mental illness in the creative geniuses of art, literature and science is higher than it is in more ordinary folk. However, this relationship between madness and genius, which was also addressed by the classical philosophers, has been generalized to all branches of professional endeavour. Whilst it may hold true for illustrious personalities of the fine arts, we found that the relationship proves inappropriate to the biographies of ten individuals renowned in history for their innovative contributions to medical science...
