Previous genome sequencing of the physiologically different B. methanolicus wild-type strains MGA3 and PB1 has unraveled all putative RuMP cycle genes and later, several of the RuMP cycle enzymes of MGA3 have been biochemically characterized. In this study, the focus was on the characterization of the transaldolase (Ta) and its possible role in the RuMP cycle in B. methanolicus. RESULTS The Ta genes of B.  https://www.selleckchem.com/products/azd9291.html  methanolicus MGA3 and PB1 were recombinantly expressed in Escherichia coli, and the gene products were purified and characterized. The PB1 Ta protein was found to be active as a homodimer with a molecular weight of 54 kDa and displayed KM of 0.74 mM and Vmax of 16.3 U/mg using Fructose-6 phosphate as the substrate. In contrast, the MGA3 Ta gene, which encodes a truncated Ta protein lacking 80 amino acids at the N-terminus, showed no Ta activity. Seven different mutant genes expressing various full-length MGA3 Ta proteins were constructed and all gene products displayed Ta activities. Moreover, MGA3 cells displayed Ta activities similar as PB1 cells in crude extracts. CONCLUSIONS While it is well established that B. methanolicus can use the SBPase variant of the RuMP cycle this study indicates that B. methanolicus possesses Ta activity and may also operate the Ta variant of the RuMP.BACKGROUND Atypical hemolytic uremic syndrome (aHUS) is a rare disease characterized by systemic thrombotic microangiopathy (TMA) reflected by hemolysis, anemia, thrombocytopenia and systemic organ injury. The optimal management of aHUS-patients when undergoing kidney transplantation to prevent recurrence in the allograft is eculizumab, an approved recombinant antibody targeting human complement component C5. CASE PRESENTATION A 39 year-old woman presented with severe abdominal pain, diarrhea and emesis for 3 days. In her past medical history she had experienced an episode of aHUS leading to end stage renal disease (ESRD) in 2007 and a genetic workup revealed a heterozygous mutation in the membrane cofactor protein gene. In 2014 she underwent cadaveric kidney transplantation. Four years later she had to go back on hemodialysis due to allograft failure following a severe systemic cytomegalovirus infection resulting in transplant failure. At presentation she still received calcineurin-inhibitor therapy and reposhowed severe inflammation due to purulent nephritis and signs of cellular rejection. After nephrectomy, we continued eculizumab therapy until the patient completely recovered. No signs of TMA recurred after discontinuation of eculizumab, further supporting the concept of the renal transplant as the main trigger of TMA of the small intestine in our patient.BACKGROUND High water hardness associated with high water fluoride and the geographical distribution of Chronic Kidney Disease of unknown etiology (CKDu) in Sri Lanka are well correlated. We undertook this study to observe the effects of high water hardness with high fluoride on kidney and liver in rats and efficacy of distilled water in reducing the effects. METHODS Test water sample with high water hardness and high fluoride was collected from Mihinthale region and normal water samples were collected from Kandy region. Twenty-four rats were randomly divided into 8 groups and water samples were introduced as follows as daily water supply. Four groups received normal water for 60 (N1) and 90 (N2) days and test water for 60 (T1) and 90 (T2) days. Other four groups received normal (N3) and test (T3) water for 60 days and followed by distilled water for additional 60 days and normal (N4) and test (T4) water for 90 days followed by distilled water for another 90 days. The rats were sacrificed following treatment.roups. CONCLUSION Hard water with high fluoride content resulted in acute tubular injury with a significant increase in serum levels of creatinine, urea and AST activity. These alterations were minimized by administering distilled water.Background Newer transoral thyroidectomy techniques that aim to avoid scars in the neck and maximize cosmetic outcomes have become more prevalent. We conducted a discrete choice experiment (DCE) to evaluate the influence of cosmetic concerns and other factors on patients' decision-making processes when choosing among different thyroidectomy approaches. Methods A questionnaire was developed to identify key attributes driving patient preferences around thyroidectomy approaches using mixed analyses of patient focus groups, expert opinion, and literature review. These attributes included 1) risk of recurrent laryngeal nerve (RLN) injury, 2) risk of mental nerve injury, 3) travel distance for surgery, 4) out-of-pocket cost, and 5) incision site. Using fractional factorial design, discrete choice sets consisting of randomly generated hypothetical scenarios across all attributes were created. A face-to-face DCE survey was administered to patients being evaluated in clinic for thyroid lobectomy for non-cancerous thyrchoosing among surgical approaches for thyroidectomy. Cosmetic considerations also influenced patient choices, but in opposing ways depending on patient age.We examined reporting of lifetime intimate partner violence (IPV) among 7,917 young women who completed two surveys, 12 months apart. At the first survey, 32% reported a history of IPV with a current or former partner. Of these, one third of women did not report IPV 12 months later (inconsistently reported IPV). Compared with women who consistently reported a history of IPV, women who inconsistently reported a history of IPV were less likely to report suicidal ideation, self-harm, illicit drug use, and smoking at the 12-month follow-up. A deeper understanding of what influences young women's reporting of IPV is needed.BACKGROUND Resistance to thyroid hormone alpha (RTHα) is a rare and under-recognized genetic disease caused by mutations of THRA, the gene encoding thyroid hormone receptor α1 (TRα1). We report here the discovery of two novel patients with missense mutations (M259T, T273A) causing RTHα. METHODS We combined biochemical and cellular assays with in silico modeling to assess the capacity of mutant TRα1 to bind T3, to heterodimerize with RXR, to interact with transcriptional coregulators and to transduce a T3 transcriptional response. RESULTS M259T, and to a lower extent T273A, reduce the affinity of TRα1 for T3. Their negative influence is only reverted by large excess of T3. CONCLUSIONS The severity of the two novel RTHα cases originates from a reduction in the binding affinity of TRα1 mutants to T3 and thus correlates with the incapacity of corepressors to dissociate from TRα1 mutants in the presence of T3.
