Deficiency in CPTII will lead to energy deficiency in the case of fasting and the accumulation of the long chain fatty in the body. There are three types of CPT II deficiency, the myopathic form, the severe infantile hepatocardiomuscular form and the lethal neonatal form. They are all inherited as an autosomal recessive. Diagnosis of the CPTII are 1) tandem mass spectrometry (MS/MS) in adult form and 2) CPTII polymorphism (F352C), which is linked to reducing the activity of CPTII in infantile form [1]. Glucose is the primary management and medium-chain fatty acid is an alternative due to the bypass of the CPTII enzyme in the pathway. For the prevention of CPTII deficiency are to avoid long chain fatty acid (C12-fatty acid), fasting, prolonged exercise, known triggers, and certain medications such as anti-epileptics and general anesthesia. During the rhabdomyolysis and myoglobinuria attack, it is very important to maintain hydration to avoid acute renal failure. If, however, renal failure occurs, dialysis is recommended. We present a case of a 27-year-old African American woman with the significant past medical history of CPT II deficiency leading to recurrent rhabdomyolysis and myoglobinuria. Together with all the research studies from diagnosis to treatment of CPTII deficiency will help in clinical management of patients. And this case report will add to the existing case reports of patients who have CPTII deficiency in terms of how we diagnose, how we treat, and how we prevent symptoms from re-occurring.展开更多

The new I-Theory predicts that elementary particles do indeed have a substructure, three dimensions, and occupy space, being composed of fundamental particles called I-particles. In this article we identify the substructural pattern of elementary particles and define the quanta of energy that form each elementary particle. We demonstrate that the substructure comprises two classes of quanta which we call “attraction quanta” and “repulsion quanta”. We create a model that defines the rest-mass energy of each elementary particle and can predict new particles. Lastly, in order to incorporate this knowledge into the contemporary models of science, a revised periodic table is proposed.展开更多

Though evidence suggests that control of secondary hyperparathyroidism may reduce cardiac endpoints, the effect of the calcimimetic agent, cinacalcet, remains controversial. This retrospective study aimed at evaluating troponin levels in hemodialysis patients with severe secondary hyper parathyroidism (SHPT) who are on cinacalcet vs controls on conventional treatment. In addition, clinical outcomes including all-cause, cardiovascular morbidity and mortality were compared among both groups. A decline in Troponin I levels was observed in the cinacalcet group, this however was not translated clinically into improved survival. In fact, all-cause and cardiac mortality was similar in the two groups. Conversely, comparison of the incidence of cardiovascular events revealed lower rates in the cinacalcet group including cardiac, cerebral and peripheral vascular complications. Given some of our study limitations, further long-term, placebo-controlled trials are necessary to definitively establish the effect of cinacalet on cardiac biomarkers and ultimately its impact on clinical outcomes.展开更多

More than two different types of sensing are also required, minimally with photovoltaics and built-in electricity. Magnetic compound fluid (MCF) rubber solar cells are made of rubber, so they are elastic and extensible as well as sensitive. To achieve flexibility and an effective photovoltaic effect, MCF rubber solar cells must include both soluble and insoluble rubbers, Fe<sub>3</sub>O<sub>4</sub>, TiO<sub>2</sub>, Na<sub>2</sub>WO<sub>4</sub>∙2H<sub>2</sub>O, etc. On the basis of this constitution, we propose a consummate fabrication process for MCF rubber solar cells. The characteristics of these cells result from the semiconductor-like role of the molecules of TiO<sub>2</sub>, Fe<sub>3</sub>O<sub>4</sub>, Ni, Na<sub>2</sub>WO<sub>4</sub>∙2H<sub>2</sub>O, polydimethylsiloxane (PDMS), natural rubber (NR), oleic acid, polyvinyl alcohol (PVA), water and magnetic cluster involved in the MCF rubber. Their tendencies can be deduced by synthesizing knowledge about the enhancement of the reverse-bias saturation current <em>I</em><sub><em>S</em></sub> and the diode ideality factor <em>N</em>, with conventional knowledge about the semiconductor affected by <em>γ</em>-irradiation and the attenuation of the photon energy of <em>γ</em>-rays.展开更多

This work aimed to study inguinal hernia in children in the general surgery department of the Reference Health Center of Commune I of the Bamako District;to determine the frequency of inguinal hernia;describe the epidemiological, clinical and therapeutic aspects of inguinal hernias and in order to evaluate the cost of treatment. This was a prospective study from April 2017 to March 2018 during which 60 children with an inguinal hernia were collected. Inguinal hernias in children represented 9.23% of patients operated on in the department. The average age was 59.23 months with extremes of one month and 180 months and a standard deviation of 49.23 years. The male sex was dominant with a sex ratio equal to 9:1. The notion of prematurity was found in 11.7% and was associated with a testicle not in place in 1.7% of cases. 41.7% of our patients were referred by a doctor and 66.7% of patients presented with painless, intermittent inguino-scrotal swelling (83.3% of cases). The hernia was discovered before one week of life in 50% of cases. Inguinal swelling was absent in 11.7% but observed intraoperatively. The inguinal hernia was unilateral in 91.7% of cases and 70% of hernias were discovered by the parents during pushing efforts. The inguinal hernia was located on the right in 61.7% of cases. The hernia swelling was soft, painless, impulsive and reducible in 78.3% of cases. The swelling was inguino-scrotal in 58.3% of cases. The hernia was simple in 95% of patients and hernial strangulation was observed in 3 cases or 5% of cases. 98.3% of patients were ASA I. The treatment was carried out openly in all our patients including closure of the vaginal peritoneal canal in 95% of cases under general anesthesia in 98.3% of cases. The morbidity rate was 8.4% (surgical site infection: 6.7% of cases and hematoma: 1.7%). The immediate consequences were simple in 96.6% of cases. No cases of recurrence occurred during the 6 months after the intervention. The average cost of care was estimated at 69,743 FCFA.展开更多

This response involves hypoxia-induced reprogramming of respiratory chain function and switching from oxidation of complex I (NAD-related substrates) to complex II (succinate oxidation). Transient, reversible, compensatory activation of respiratory chain complex II is a major mechanism of urgent adaptation to hypoxia, which is necessary for 1) succinate-related energy synthesis in the conditions of oxygen shortage and formation of urgent resistance;2) succinate-related stabilization of HIF-1α and initiation of its transcriptional activity related with formation of long-term adaptation;3) succinate-dependent activation of the succinate-specific receptor GPR91. Thus, mitochondria perform a signaling function with succinate as a signaling molecule. Effects of succinate in hypoxia occur at three levels, intramitochondrial, intracellular and intercellular. In these settings, succinate displays antihypoxic activity. The review is focused on tactics and strategy for development of the antihypoxic defense and antihypoxants with energotropic properties.展开更多

Methods: In successive developed gastric outlet and esophageal strictures a limited Billroth I resection (in 9) or conversion a prior precolic GEA in such anastomosis (in 5) and middle or total gastrectomies (in 3) were performed. A second stage substernal by-pass with isoperistaltic transverse colon segment was done 6 - 12 weeks later. In all but one instances the graft was implanted high in the gastric stump. In extensive burned and retracted such lesion (in 3) a similar by-pass was carried out but the lower anastomosis was done with the not involved prepyloric segement. In concomittant antropyloric and esophageal strictures in 11 young, good risk patients, a limited Billroth I resction and simultaneous colonic bypass was used. In case of accompanied respiratory fistula (in 4) exclusion by-pass was useful for both lesions. The associated pyloric stricture (in 3) was solved at the same time. Side-to-end pharyngocolostomy was used in 4 high thoracocervical strictures. In 8 previously perforated strictures the by-ass was performed 2 months later. Reults: The overall mortality was 4%. The postoperative morbidity was low (8%). All cervical leaks closed spontaneously. Particular late complications required revisional surgery in 12, 5% of cases. Conclusion: In complicated corrosive strictures (esophageal, gastric, fistulas) limited Billoth I resection, isoperistaltic colon by-pass with high gastrocolic anastomosis, good gastric drainage and maintenance of the duodenum in gastrointestinal continuity are the main factors to achieve the best functional results.展开更多

In this study, mice were subjected to 10 minutes of ischemic preconditioning, and persimmon leaf flavonoid was orally administered for 5 days. Results showed that the persimmon leaf fiavonoid significantly improved the content of tissue type plasminogen activator and 6-keto prostaglandin-F1 a in the cerebral cortex, decreased the content of thromboxane B2, and reduced the content of plasminogen activator inhibitor-1 in mice. Following optical microscopy, persimmon leaf flavonoid was also shown to reduce cell swelling and nuclear hyperchromatism in the cerebral cortex and hippocampus of mice. These results suggested that persimmon leaf fiavonoid can effectively inhibit brain thrombosis, improve blood supply to the brain and relieve ischemia-induced pathological damage, resulting in brain ischemic tolerance.展开更多

Methods: 1145 SSc patients had ANA and ENA analyzed by indirect immunofluorescence on HEp-2 substrate at a screening serum dilution of 1/160. Most ENA antibodies [Sm. U1-RNP, Ro52, SS-A/Ro60, topoisomeraseI (Topo1), SS-B/La, chromatin, ribosomal P and Jo1] were measured by laser bead immunoassay;and RNA polymerase III (RNAP) by ELISA. Results: ANA was positive in 95% (same in lcSSc, and dcSSc). Centromere pattern was present in 34%, speckled 22%, nucleolar 18%, homogeneous and speckled (H&S) 16%, multiple nuclear dots 6%. Anti-centromere Ab (ACA) occurred in 46% of lcSSc and 11% of dcSSc (P = 0.0001). ENAs that differed between lcSSc and dcSSc subsets were Topo1 (OR 2.4, P = 0.0001) and RNAP (OR 5.6, P 0.0001) more common in dcSSc. Overall, 15% had positive Topo1;usually with a H&S pattern (67%);Topo1 was associated with ILD on CXR (OR 2.3;95% CI 1.5 - 3.5) and HRCT (OR 3.8;95% CI 1.8 - 8.2). RNAP occurred in 18.5% (35.4% in dcSSc vs. 8.9% in lcSSc). Scleroderma renal crisis (SRC) was 13 times more likely if RNAP positive;P = 0.0001. ACA was only weakly associated with sPAP > 50 mmHg (OR 1.8;95%CI 1.1 - 3.0). Conclusion: ANA homogeneous pattern alone is rare in SSc;ACA was significantly more common in lcSSc. Many ENAs are equal in lcSSc and dcSSc except RNAP and Topo1. RNAP has the highest OR of SRC. Topo1 is less strongly associated with ILD. Abstract word count: 249, Body word count 1246, Figures 2, Tables 2. Key Messages: 1) 95% of SSc has a positive ANA and ANA patterns in SSc include centromere, nucleolar, and homogeneous and speckled together;2) Most ENAs are equal in both dcSSc and lcSSc except anti RNA polymerase III and topoisomerase I;3) RNA polymerase III has the highest association (odds ratio) with scleroderma renal crisis, topoisomerase I is associated with interstitial lung disease;whereas anticentromere was not associated with elevated pulmonary arterial pressures on echocardiogram.展开更多

The reverse cholesterol transport, a pathway of choles-terol from peripheral tissue to liver which has several potent antiatherogenic properties. For instance, the particles of HDL mediate to transport cholesterol from cells in arterial tissues, particularly from atherosclerotic plaques, to the liver. Both ATP-binding cassette trans-porters(ABC) A1 and ABCG1 are membrane cholesterol transporters and have been implicated in mediating cholesterol effluxes from cells in the presence of HDL and apolipoprotein A-I, a major protein constituent of HDL. Previous studies demonstrated that ABCA1 and ABCG1 or the interaction between ABCA1 and ABCG1 exerted antiatherosclerotic effects. As a therapeutic approach for increasing HDL cholesterol levels, much focus has been placed on increasing HDL cholesterol levels as well as enhancing HDL biochemical functions. HDL therapies that use injections of reconstituted HDL, apoA-I mimetics, or full-length apoA-I have shown dramatic effectiveness. In particular, a novel apoA-I mi-metic peptide, Fukuoka University ApoA-I Mimetic Pep-tide, effectively removes cholesterol via specific ABCA1 and other transporters, such as ABCG1, and has an an-tiatherosclerotic effect by enhancing the biological func-tions of HDL without changing circulating HDL choles-terol levels. Thus, HDL-targeting therapy has significant atheroprotective potential, as it uses lipid transporter-targeting agents, and may prove to be a therapeutic tool for atherosclerotic cardiovascular diseases.展开更多

Case Report: We report the case of a 36-year-old with severe scoliosis status post repair over a decade ago, neurofibromatosis type I, and a known large meningocele in the left thoracic cavity, presenting with new acute respiratory compromise. She was taken to the operating room for a lumboperitoneal shunt, but the operation was aborted due to her severe spinal deformity. Two days later, she successfully underwent a procedure for ventriculoperitoneal shunt placement. Upon discharge a week later, the patient was hemodynamically stable, able to move all extremities with good strength, and demonstrated improved oxygenation. In the following 7 months, the patient demonstrated continued minimal requirement on nasal cannula, and MRI showed a stable left thoracic giant meningocele. Conclusion: Ventriculoperitoneal shunting is a method of treating and stabilizing acutely symptomatic giant meningoceles.展开更多
文摘Carnitine Palmitoyl Transferase II (CPTII) is a very important enzyme that helps with the oxidation of long-chain fatty acid to produce energy. Deficiency in CPTII will lead to energy deficiency in the case of fasting and the accumulation of the long chain fatty in the body.

文摘This paper focuses on a bioenergetic mechanism responding to hypoxia. This response involves hypoxia-induced reprogramming of respiratory chain function and switching from oxidation of complex I (NAD-related substrates) to complex II (succinate oxidation). Transient, reversible, compensatory activation of respiratory chain complex II is a major mechanism of urgent adaptation to hypoxia, which is necessary for 1) succinate-related energy synthesis in the conditions of oxygen shortage and formation of urgent resistance;2) succinate-related stabilization of HIF-1α and initiation of its transcriptional activity related with formation of long-term adaptation;3) succinate-dependent activation of the succinate-specific receptor GPR91. Thus, mitochondria perform a signaling function with succinate as a signaling molecule. Effects of succinate in hypoxia occur at three levels, intramitochondrial, intracellular and intercellular. In these settings, succinate displays antihypoxic activity. The review is focused on tactics and strategy for development of the antihypoxic defense and antihypoxants with energotropic properties.

文摘Objectives: The main steps for physiologic type reconstruction in 50 complicated corrosive strictures of upper alimentary tract are presented. Methods: In successive developed gastric outlet and esophageal strictures a limited Billroth I resection (in 9) or conversion a prior precolic GEA in such anastomosis (in 5) and middle or total gastrectomies (in 3) were performed. A second stage substernal by-pass with isoperistaltic transverse colon segment was done 6 - 12 weeks later. In all but one instances the graft was implanted high in the gastric stump. In extensive burned and retracted such lesion (in 3) a similar by-pass was carried out but the lower anastomosis was done with the not involved prepyloric segement. In concomittant antropyloric and esophageal strictures in 11 young, good risk patients, a limited Billroth I resction and simultaneous colonic bypass was used. In case of accompanied respiratory fistula (in 4) exclusion by-pass was useful for both lesions. The associated pyloric stricture (in 3) was solved at the same time. Side-to-end pharyngocolostomy was used in 4 high thoracocervical strictures. In 8 previously perforated strictures the by-ass was performed 2 months later. Reults: The overall mortality was 4%. The postoperative morbidity was low (8%). All cervical leaks closed spontaneously. Particular late complications required revisional surgery in 12, 5% of cases. Conclusion: In complicated corrosive strictures (esophageal, gastric, fistulas) limited Billoth I resection, isoperistaltic colon by-pass with high gastrocolic anastomosis, good gastric drainage and maintenance of the duodenum in gastrointestinal continuity are the main factors to achieve the best functional results.

文摘The persimmon leaf has been shown to improve cerebral ischemic outcomes; however, its mechanism of action remains unclear. In this study, mice were subjected to 10 minutes of ischemic preconditioning, and persimmon leaf flavonoid was orally administered for 5 days. Results showed that the persimmon leaf fiavonoid significantly improved the content of tissue type plasminogen activator and 6-keto prostaglandin-F1 a in the cerebral cortex, decreased the content of thromboxane B2, and reduced the content of plasminogen activator inhibitor-1 in mice. Following optical microscopy, persimmon leaf flavonoid was also shown to reduce cell swelling and nuclear hyperchromatism in the cerebral cortex and hippocampus of mice. These results suggested that persimmon leaf fiavonoid can effectively inhibit brain thrombosis, improve blood supply to the brain and relieve ischemia-induced pathological damage, resulting in brain ischemic tolerance.
文摘Objective: Serum from SSc patients was analyzed centrally to determine ANA patterns and extractable nuclear antigens (ENAs) between lcSSc and dcSSc and associations with organ involvement. Methods: 1145 SSc patients had ANA and ENA analyzed by indirect immunofluorescence on HEp-2 substrate at a screening serum dilution of 1/160. Most ENA antibodies [Sm. U1-RNP, Ro52, SS-A/Ro60, topoisomeraseI (Topo1), SS-B/La, chromatin, ribosomal P and Jo1] were measured by laser bead immunoassay;and RNA polymerase III (RNAP) by ELISA. Results: ANA was positive in 95% (same in lcSSc, and dcSSc). Centromere pattern was present in 34%, speckled 22%, nucleolar 18%, homogeneous and speckled (H&S) 16%, multiple nuclear dots 6%. Anti-centromere Ab (ACA) occurred in 46% of lcSSc and 11% of dcSSc (P = 0.0001). ENAs that differed between lcSSc and dcSSc subsets were Topo1 (OR 2.4, P = 0.0001) and RNAP (OR 5.6, P 0.0001) more common in dcSSc. Overall, 15% had positive Topo1;usually with a H&S pattern (67%);Topo1 was associated with ILD on CXR (OR 2.3;95% CI 1.5 - 3.5) and HRCT (OR 3.8;95% CI 1.8 - 8.2). RNAP occurred in 18.5% (35.4% in dcSSc vs. 8.9% in lcSSc). Scleroderma renal crisis (SRC) was 13 times more likely if RNAP positive;P = 0.0001. ACA was only weakly associated with sPAP > 50 mmHg (OR 1.8;95%CI 1.1 - 3.0). Conclusion: ANA homogeneous pattern alone is rare in SSc;ACA was significantly more common in lcSSc. Many ENAs are equal in lcSSc and dcSSc except RNAP and Topo1. RNAP has the highest OR of SRC. Topo1 is less strongly associated with ILD. Abstract word count: 249, Body word count 1246, Figures 2, Tables 2. Key Messages: 1) 95% of SSc has a positive ANA and ANA patterns in SSc include centromere, nucleolar, and homogeneous and speckled together;2) Most ENAs are equal in both dcSSc and lcSSc except anti RNA polymerase III and topoisomerase I;3) RNA polymerase III has the highest association (odds ratio) with scleroderma renal crisis, topoisomerase I is associated with interstitial lung disease;whereas anticentromere was not associated with elevated pulmonary arterial pressures on echocardiogram.

文摘BACKGROUND The retrospective review of I-ring pupil expansion ring use is designed to examine the patient characteristics and associated surgical challenges in a clinical practice.The hypothesis is that I-ring provides a necessary additive tool in dealing with challenging cataract surgeries with small pupils.AIM To document the safety profile and use of I-ring pupil expansion ring in a clinical practice.METHODS A retrospective chart review of 12 consecutive cases within the same year(2016)of cataract surgeries employing I-ring pupil expansion ring(Beaver-Visitec,International)by a single surgeon at the same ambulatory surgical center was conducted.Demographic,pre-op,intra-op,and post-op data were recorded.Total number of cataract cases performed was also recorded.RESULTS 8 of 12 cases were planned I-ring cases.1 case was decided intraoperatively when femtosecond laser caused the pupil to shrink.The other 3 cases were also decided upon intraoperatively when pupil was deemed to be small.7 patients had IFIS from Flomax use.2 patients had pseudoexfoliation syndrome as the cause of small pupil.2 patients had narrow angles with brunescent cataracts.2 patients had pre-op partial zonular dehiscence.1 patient had 360o of posterior synechiae.2 cases had ruptured posterior capsule that required anterior vitrectomy.No complications were attributed to the pupil expansion ring.A total of 296 cataract surgeries were performed that year by the surgeon,making the rate of pupil ring use 4.1%.CONCLUSION Small pupil requiring pupil expansion ring during cataract surgery is often associated with other challenges,such as brunescent cataract,zonular weakness,and posterior synechiae in this series.I-ring helped to reduce at least one challenge in these difficult cases.
文摘Various previous studies have found a negative cor-relation between the risk of cardiovascular events and serum high-density lipoprotein(HDL) cholesterol levels. The reverse cholesterol transport, a pathway of choles-terol from peripheral tissue to liver which has several potent antiatherogenic properties. For instance, the particles of HDL mediate to transport cholesterol from cells in arterial tissues, particularly from atherosclerotic plaques, to the liver. Both ATP-binding cassette trans-porters(ABC) A1 and ABCG1 are membrane cholesterol transporters and have been implicated in mediating cholesterol effluxes from cells in the presence of HDL and apolipoprotein A-I, a major protein constituent of HDL. Previous studies demonstrated that ABCA1 and ABCG1 or the interaction between ABCA1 and ABCG1 exerted antiatherosclerotic effects. As a therapeutic approach for increasing HDL cholesterol levels, much focus has been placed on increasing HDL cholesterol levels as well as enhancing HDL biochemical functions. HDL therapies that use injections of reconstituted HDL, apoA-I mimetics, or full-length apoA-I have shown dramatic effectiveness. In particular, a novel apoA-I mi-metic peptide, Fukuoka University ApoA-I Mimetic Pep-tide, effectively removes cholesterol via specific ABCA1 and other transporters, such as ABCG1, and has an an-tiatherosclerotic effect by enhancing the biological func-tions of HDL without changing circulating HDL choles-terol levels. Thus, HDL-targeting therapy has significant atheroprotective potential, as it uses lipid transporter-targeting agents, and may prove to be a therapeutic tool for atherosclerotic cardiovascular diseases.
文摘Objective: The authors report a rare case of giant thoracic meningocele causing acute respiratory compromise, treated with a ventriculoperitoneal shunt. Case Report: We report the case of a 36-year-old with severe scoliosis status post repair over a decade ago, neurofibromatosis type I, and a known large meningocele in the left thoracic cavity, presenting with new acute respiratory compromise. She was taken to the operating room for a lumboperitoneal shunt, but the operation was aborted due to her severe spinal deformity. Two days later, she successfully underwent a procedure for ventriculoperitoneal shunt placement. Upon discharge a week later, the patient was hemodynamically stable, able to move all extremities with good strength, and demonstrated improved oxygenation. In the following 7 months, the patient demonstrated continued minimal requirement on nasal cannula, and MRI showed a stable left thoracic giant meningocele. Conclusion: Ventriculoperitoneal shunting is a method of treating and stabilizing acutely symptomatic giant meningoceles.
