Michael Fischer
Zeolites and structurally related materials (zeotypes) have received considerable attention as potential adsorbents for selective carbon dioxide adsorption. Within this group, zeotypes with aluminophosphate composition (AlPOs) could be an interesting alternative to the more frequently studied aluminosilicate zeolites. So far, however, only a few AlPOs have been characterised experimentally in terms of their CO2 adsorption properties. In this study, force-field based grand-canonical Monte Carlo (GCMC) simulations were used to evaluate the potential of AlPOs for CO2/N2 separation, a binary mixture that constitutes a suitable model system for the removal of carbon dioxide from flue gases...

Currently, little information is available to stratify the risks and predict acute kidney injury (AKI)-associated death. In this present cross-sectional study, a novel scoring model was established to predict the probability of death within 90 days in patients with AKI diagnosis. For establishment of predictive scoring model, clinical data of 1169 hospitalized patients with AKI were retrospectively collected, and 731 patients of them as the first group were analyzed by the method of multivariate logistic regression analysis to create a scoring model and further predict patient death...

Pharmaceutical products including analgesics, antibiotics, and antiepileptics are often present in wastewater treatment effluents, lakes, and rivers and have been found in waterways of many countries. The adsorption of two common pharmaceuticals present in surface waters, clarithromycin (CLR) and atenolol (ATN), onto cuttlefish bone powder treated with HCl has been investigated. Adsorption experiments were carried out at different pH conditions and the experimental equilibrium data were fitted to the Langmuir and Freundlich...

INTRODUCTION: Amlodipine is a third generation dihydropyridine group of calcium channel blocker and having an excellent antihypertensive profile. Pedal Oedema (PE) is the major drawback of amlodipine therapy and the incidence of Amlodipine Induced Pedal Oedema (AIPE) has been found significantly high. Several neurohumoral factors influence the incidence of oedema. AIM: We aimed to compare the plasma levels of renin, vasopressin and atrial natriuretic peptide in hypertensive AIPE, non-oedema and cilnidipine treated patients...

The mitochondrial genome (mt genome) provides important information for understanding molecular evolution and phylogenetics. As such, the two complete mt genomes of Ampelophaga rubiginosa and Rondotia menciana were sequenced and annotated. The two circular genomes of A. rubiginosa and R. menciana are 15,282 and 15,636 bp long, respectively, including 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes and an A + T-rich region. The nucleotide composition of the A. rubiginosa mt genome is A + T rich (81...

Acanthoscelides obtectus is a common species of the subfamily Bruchinae and a worldwide-distributed seed-feeding beetle. The complete mitochondrial genome of A. obtectus is 16,130 bp in length with an A + T content of 76.4%. It contains a positive AT skew and a negative GC skew. The mitogenome of A. obtectus contains 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes and a non-coding region (D-loop). All PCGs start with an ATN codon, and seven (ND3, ATP6, COIII, ND3, ND4L, ND6, and Cytb) of them terminate with TAA, while the remaining five (COI, COII, ND1, ND4, and ND5) terminate with a single T, ATP8 terminates with TGA...

The anterior thalamic nuclei (ATN) and the intralaminar/lateral thalamic nuclei (ILN/LT) play different roles in memory processes. The ATN are believed to be part of an extended hippocampal system, and the ILN/LT have strong connections with the medial prefrontal cortex. It was shown that the ILN/LT are involved in systems consolidation. However, whether they are necessary for memory retrieval as well remains unclear. We, therefore, used c-Fos immunohistochemistry and reversible inactivations to investigate the role of the ATN and ILN/LT in recent and remote contextual fear memory retrieval in rats...

OBJECTIVE: To evaluate the efficacy and safety of atorvastatin (ATN) 80 mg in the prevention of contrast medium- induced nephropathy (CIN) in high risk patients undergoing angiograph. MATERIALS AND METHODS: This was a prospective, double-blind, two-arm, parallel group RCT. A total of 216 patients undergoing coronary angiography were screened, and 188 eligible patients were randomized to two treatment arms. Patients in Group A received tablet N-acetylcysteine (NAC) 1200 mg once daily, and patients in Group B received tablet atorvastatin 80 mg + NAC 1200 mg once daily, for 3 days before, and 2 days after angiography...

Rodent granular retrosplenial cortex (GRS) has dense connections between the anterior thalamic nuclei (ATN) and hippocampal formation. GRS superficial pyramidal neurons exhibit distinctive late spiking (LS) firing property and form patchy clusters with prominent apical dendritic bundles. The aim of this study was to investigate spatio-temporal dynamics of signal transduction in the GRS induced by ATN afferent stimulation by using fast voltage-sensitive dye imaging in rat brain slices. In coronal slices, layer 1a stimulation, which presumably activated thalamic fibers, evoked propagation of excitatory synaptic signals from layers 2-4 to layers 5-6 in a direction perpendicular to the layer axis, followed by transverse signal propagation within each layer...

OBJECTIVE: To research Angelica tenuissima Nakai (ATN) for use in novel Alzheimer's disease (AD) therapeutics. METHODS: The effect of a 30% ethanol extract of ATN (KH032) on AD-like cognitive impairment and neuropathological and neuroinflammatory changes induced by bilateral intracerebroventricular injections of β-amyloid (Aβ) peptide (Aβ1-42) was investigated. Male C57Bl/6 mice were randomly divided into 4 groups, 10 in each group. KH032-treated groups were administrated with a low or high dose of KH032 (50 and 200 mg/kg, respectively), intragastrically for 16 days; distilled water was applied in the sham and negative groups...

We have shown that a novel STAT3 inhibitor arctigenin (Atn) induces significant cytotoxicity in triple-negative breast cancer (TNBC) cells. This study further delineated molecular mechanisms where by Atn triggered cytotoxicity in TNBC cells. We found Atn can also inhibit metastasis in TNBC cells through cancerous inhibitor of protein phosphatase 2A (CIP2A) pathway. CIP2A is an endogenous inhibitor of protein phosphatase 2A (PP2A), which can increase the migration and invasion of various cancer cells. PP2A is a tumor suppressor, which is functionally defective in various cancers...

AIMS: Increases in the systemic vasodilator adrenomedullin and the renal vasoconstrictors thromboxane A2 (TXA2 ) in cirrhotic patients are pathogenic factors for the development of functional acute-kidney-injury, including pre-renal azotemia (PRA) and hepatorenal syndrome (HRS), which is associated with high mortality. This study aims to find biomarkers which can diagnose HRS in early stage for treating it as soon as possible. METHODS: Acute decompensated cirrhotic patients who had been admitted to hospital were enrolled in this prospective cohort study...

Renal dysfunction is a common complication of liver cirrhosis and of utmost clinical and prognostic relevance. Patients with cirrhosis are more prone to developing acute kidney injury (AKI) than the non-cirrhotic population. Pre-renal AKI, the hepatorenal syndrome type of AKI (HRS-AKI, formerly known as 'type 1') and acute tubular necrosis represent the most common causes of AKI in cirrhosis. Correct differentiation is imperative, as treatment differs substantially. While pre-renal AKI usually responds well to plasma volume expansion, HRS-AKI and ATN require different specific approaches and are associated with substantial mortality...
