Hibernation impact on the catalytic activities of the mitochondrial D-3-hydroxybutyrate dehydrogenase in liver and brain tissues of jerboa (Jaculus o…
2003
Abstract Background Jerboa (Jaculus orientalis) is a deep hibernating rodent native to subdesert highlands. During hibernation, a high level of ketone bodies i.e. acetoacetate (AcAc) and D-3-hydroxybutyrate (BOH) are produced in liver, which are used in brain as energetic fuel. These compounds are bioconverted by mitochondrial D-3-hydroxybutyrate dehydrogenase (BDH) E.C. 1.1.1.30. Here we report, the function and the expression of BDH in terms of catalytic activities, kinetic parameters, levels of protein and mRNA in both tissues i.e brain and liver, in relation to the hibernating process. Results We found that: 1/ In euthemic jerboa the specific activity in liver is 2.4- and 6.4- fold high…
Massive digoxin intoxication in childhood.
1978
In a 10 year old boy 8 hours after taking about 16 mg beta-acetyl-digoxin a maximum serum digoxin level of 31.8 ng/ml was measured radioimmunologically. This is the highest digitalis level in childhood described to date. The serum potassium level rose to 7.4 mmol/l. Complete atrio-ventricular block, and salves of ventricular premature beats were the most serious rhythm disturbances. The absence of life threatening rhythm disturbances is attributed to the early use of diphenylhydantoin in small frequent doses.
Fruit and vegetable consumption and sarcopenia among older adults in low- and middle-income countries
2020
Fruit and vegetable consumption may protect against sarcopenia but there are no studies on this topic from low- and middle-income countries (LMICs). Thus, we assessed this association among older adults from six LMICs. Community-based cross-sectional data of the Study on Global Aging and Adult Health were analyzed. Sarcopenia was defined as the presence of low skeletal muscle mass based on indirect population formula, and either slow gait or low handgrip strength. Quintiles of vegetable and fruit consumption were created based on the number of servings consumed on a typical day. Multivariable logistic regression analysis was conducted. The sample consisted of 14,585 individuals aged &ge
Being hospitalized with a newly diagnosed chronic illness - A phenomenological study of children’s lifeworld in the hospital
2012
The impact of a hospital environment on children has rarely been investigated. Recently, however, the perspective of hospitalized children has been taken into account. Being hospitalized and facing an illness represent a dramatic change in a child’s daily life, and the quality of the environment may influence the child’s experiences. The aim of this study was to investigate the experiences of children being hospitalized with newly diagnosed type 1 diabetes and to obtain an increased understanding of the environmental influences on the children’s lifeworld. The study used a hermeneutic phenomenological approach. The design is a combination of observation of the participant, interviews, and p…
Hydrops, fetal pleural effusions and chylothorax in three patients with CBL mutations.
2014
Fetal hydrops, fetal pleural effusions, hydrothorax, and chylothorax, may be associated with various genetic disorders, in particular with the Noonan, cardio-facio-cutaneous and Costello syndromes. These syndromes, collectively called RASopathies, are caused by mutations in the RAS/MAPK pathway, which is known to play a major role in lymphangiogenesis. Recently, germline mutations in the Casitas B-cell lymphoma (CBL) gene were reported in 25 patients and of these, 20 had juvenile myelomonocytic leukemia (JMML). The disorder was named "CBL syndrome" or "Noonan syndrome-like disorder with or without juvenile myelomonocytic leukemia" (NSLL). To date, prenatal abnormalities have not been report…
Are antiphospholipid antibodies an essential requirement for an effective immune response to infections?
2007
Antiphospholipid antibodies show a close association to a variety of infections. Recent data implicate that parvovirus B19 may be used as a model-system for studying the interaction of viral infection and the development of these autoantibodies. B19-related diseases commonly associated with the acute infection show flu-like symptoms, transient arthralgias, leukopenia and thrombocytopenia, and, in pregnant women, spontaneous abortion and hydrops fetalis. Hepatitis, myocarditis, meningitis, encephalitis, as well as pure red cell anemia may occur occasionally. In addition, parvovirus B19 infections have been frequently described as the cause or trigger of various forms of autoimmune diseases a…
Lysosomal storage disorder in non-immunological hydrops fetalis (NIHF) - more common than assumed? Report of four cases with transient NIHF and a rev…
2012
Abstract Background Lysosomal storage disorders (LSD) are a rare cause of non immunological hydrops fetalis (NIHF) and congenital ascites. The reported incidence is about 1%. The incidence of idiopathic NIHF is estimated to be about 18%. Patients and methods We report four cases with transient hydrops fetalis resulting from LSD and performed a literature review on LSD with NIHF and congenital ascites in combination. Results At present, 12 different LSDs are described to be associated with NIHF or congenital ascites. Most patients had a family history of NIHF, where the preceding sibling had not been examined. A diagnostic approach to the fetus with NIHF due to suspected LSD either in utero …
Regulation of cell-to-cell communication in non-tumorigenic and malignant human prostate epithelial cells.
2002
BACKGROUND Gap-junction-mediated intercellular communication (GJIC) is required for normal development and tissue homeostasis. However, the role of GJIC in human prostate carcinogenesis and progression remains ill-defined. METHODS The ability of hormones, anti-hormones, and the anti-hypertensive drug, forskolin, to restore GJIC in non-tumorigenic (RWPE-1 and PWR-1E) and malignant (RWPE-2, LNCaP, DU-145) human prostate epithelial cell lines, was examined by Scrape-Loading/Dye Transfer (SL/DT) and Fluorescence Recovery After Photobleaching (FRAP) methods using an Ultima laser cytometer. RESULTS Results from both assays show that PWR-1E, RWPE-2, LNCaP, and DU-145 cells have weak or absent GJIC…
Relationship between HRV measurements and demographic and clinical variables in a population of patients with atrial fibrillation.
2015
Little is known about the role of HRV in atrial fibrillation (AF) patients. Aim of our study was to assess the relationship between HRV measurements and demographic and clinical variables in a population of 274 AF patients. We selected all consecutive patients with persistent/permanent AF among whom had performed a Holter ECG in our Department from April 2010 to April 2015. Time-domain analysis of HRV was evaluated. Demographic and clinical variables were collected for each patient. At multivariable logistic regression, a higher pNN50 was associated with ACE inhibitors/ARBs (p = 0.016) and a lower pNN50 with obesity (p = 0.037) and higher heart rate (HR) (p < 0.0005). A higher RMSSD w…
Institutional systems inducing R&D in Amazon- the role of an investor surplus toward stakeholder capitalization
2020
Abstract Amazon demonstrated a conspicuous increase in R&D and became the world's top R&D firm in 2017 with a skyrocketing increase in market capitalization, making it close to being the world's biggest company. Such a remarkable accomplishment can be attributed to Amazon's institutional systems, which orchestrate techno-financing systems that fuse a unique R&D transformation system and a sophisticated financing system centered on the cash conversion cycle (CCC). These institutional systems support and endorse aggressive investment in R&D that incorporates the characteristics of uncertainty, a long lead time, and successive inflows of very large amounts of funding without interruption. Whil…
