BACKGROUND: Although several types of diet have been used in experimental steatohepatitis models, comparison of gut microbiota and immunological alterations in the gut among diets has not yet been performed. AIM: We attempted to clarify the difference in the gut environment between mice administrated several experimental diets. METHODS: Male wild-type mice were fed a high-fat (HF) diet, a choline-deficient amino acid-defined (CDAA) diet, and a methionine-choline-deficient (MCD) diet for 8 weeks...

In healthcare practice, care providers are confronted with tragic situations, in which they are expected to make choices and decisions that can have far-reaching consequences. This article investigates the role of moral case deliberation (MCD) in dealing with tragic situations. It focuses on experiences of care givers involved in the treatment of a pregnant woman with a brain tumour, and their evaluation of a series of MCD meetings in which the dilemmas around care were discussed. The study was qualitative, focusing on the views and experiences of the participants...

Castleman's disease (CD) is a rare lymphoproliferative disorder that has multiple histologic patterns, as well as two distinct clinical forms: unicentric or multicentric. Multicentric Castleman's disease (MCD) may have mild symptoms in some cases, but in others it can progress to severe pancytopenia, life-threatening infection, secondary malignancy, multiorgan failure, or death. Recent research has determined that the etiology of the disease signs and symptoms is related to elevated cytokines, including interleukin 6 (IL-6)...

Non-alcoholic fatty liver disease (NAFLD) is a prevalent obesity-related disease that affects large populations throughout the world due to excessive calorie intake and an increasingly sedentary lifestyle. Fibroblast growth factor 21 (FGF21) has recently emerged as a promising therapeutic candidate for the treatment of obesity and diabetes. FGF21 is a starvation-induced pleiotropic hormone with various beneficial metabolic effects, and pharmacological treatment in rodents has been shown to improve insulin sensitivity and decrease simple fatty liver disease...

This is a case presentation of a HHV8-positive multicentric Castleman's disease (MCD) of plasma cell type. The patient failed to respond to combined immunosuppressive therapy and monoclonal anti-CD20 therapy. Interestingly, administration of anti-IL-6R antibody stabilized the disease and resulted in clearance of HHV8 from the involved lymph nodes.

BACKGROUND AND AIMS: Relatively few cannabis dependent individuals seek treatment and little is known about the determinants of treatment seeking. Social Cognitive Theory (SCT) provides a useful framework for examining human behaviour and motivation which may be helpful in explaining treatment seeking. This study examined the differences in cannabis outcome expectancies and cannabis refusal self-efficacy between treatment seekers and non-treatment seekers with cannabis dependence. DESIGN: Non-treatment seekers were referred to an illicit drug diversion program...

Increasing evidence has accrued which indicates that mesenchymal stem cells (MSCs) have a potential clinical value in the treatment of certain diseases. Globally, nonalcoholic steatohepatitis (NASH) is a widespread disorder. In the present study, MSCs were isolated successfully from compact bone and a mouse model of NASH was established as achieved with use of a methionine-choline deficient (MCD) diet. Compact bone-derived MSCs transplantation reduced MCD diet-induced weight loss, hepatic lipid peroxidation, steatosis, ballooning, lobular inflammation and fibrogenesis...

Cell fate determination factor dachshund1 (DACH1) is a chromosome-associated protein that regulates cellular differentiation throughout development. Recent genome-wide association studies have show that missense mutation in DACH1 leads to hereditary renal hypodysplasia. Renal DACH1 expression can be used to estimate glomerular filtration rate (eGFR). We firstly characterized the function of DACH1 in normal and diseased renal tissue using immunohistochemistry to assess DACH1 in human renal biopsy specimens from 40 immunoglobulin A nephropathy (IgAN) patients, 20 idiopathic membranous nephropathy (IMN) patients, and 15 minimal change disease (MCD) patients...

A 'two birds, one stone' strategy was developed via a one-pot click reaction to simultaneously prepare a novel cyclodextrin (CD) dimer based aggregation induced emission (AIE) sensor (AIE-DCD) and a monomer based chiral stationary phase (CSP-MCD) for chiral high performance liquid chromatography (CHPLC). AIE-DCD was found to afford satisfactory AIE response for specific detection of Zn(2+) with a detection limit of 50 nM. CSP-MCD exhibits excellent enantioseparation ability toward dansyl amino acids, where the resolution of dansyl amino leucine reaches 5...

BACKGROUND: Drug-related outcomes expectancies and refusal self-efficacy are core components of Social Cognitive Theory. Both predict treatment outcome in alcohol use disorders. Few studies have reported expectancies and refusal self-efficacy in cannabis dependence. None have examined both, although both constructs are key targets in Cognitive-Behavioural Therapy (CBT). This study tests the predictive role of expectancies and refusal self-efficacy in treatment outcome for cannabis dependence...

BACKGROUND AND AIMS: Since non-alcoholic steatohepatitis (NASH) is associated with impaired liver regeneration, we investigated the effects of G49, a dual glucagon-like peptide-1(GLP-1)/glucagon (GCG) receptor agonist, on NASH and hepatic regeneration. METHODS: C57Bl/6 mice fed chow or methionine and choline-deficient (MCD) diet for one week were divided into 4 groups: C (chow diet), MCD (MCD diet), C+G49 (chow diet plus G49) and M+G49 (MCD diet plus G49). Mice fed high fat diet (HFD) for 10 weeks were divided in groups: HFD and H+G49 (HFD plus G49)...

A unique combination of two independent mechanisms of fluorescence quenching, intramolecular charge transfer (ICT) from a peripheral donor and protonation of azomethine nitrogens in zinc tetrapyrazinoporphyrazines (TPyzPz) provides a new possibility for sensing pH in a specific range. The pH selectivity was controlled by the different basicities of the donor for ICT (dimethylaminoaryl), connected to the macrocycle by π-extended linkers of different lengths. ICT and protonation were studied in detail by photophysical, spectral (UV-Vis and MCD spectra) and electrochemical measurements that were further supported by theoretical calculations (DFT, TDDFT)...

A hypercoagulable state exists in patients with nephrotic syndrome (NS), which more easily leads to venous thromboembolism (VTE). However, whether acute kidney injury (AKI), a common complication of NS, affects the hypercoagulable state and VTE has rarely been elucidated. In this study, we aimed to explore coagulation changes and analyze relevant influencing factors in NS-AKI patients.A total of 269 consecutive NS patients with minimal change disease (MCD) between 2011 and 2016 were included in this observational study...

Associations between mast cell infiltration and the clinical features and known molecular profile of breast cancer remain unclear. The distribution difference of mast cell was evaluated, in 219 patients with no special type of invasive carcinoma, using sorts of age, max diameter of cancer, histological type, lymph node metastasis as well as the expressions of estrogen receptor (ER), progestogen receptor (PR), human epidermal growth factor receptor 2 (HER-2) and nuclear protein Ki67. The mast cell density (MCD) in patients younger than 50 years old was significantly higher than that in patients with age ≥ 50...

Cutaneous manifestations are well-recognized complications of Crohn disease (CD) that can be divided into disease-specific and reactive conditions. One of the most common reactive conditions is erythema nodosum (EN), which presents as subcutaneous tender nodules most often on the legs. On the other hand, metastatic Crohn disease (MCD) is a rare cutaneous manifestation of CD defined as the presence of noncaseating granulomas that are not contiguous with the gastrointestinal (GI) tract. The clinical presentation of MCD is variable; however, lesions often are located on the legs and genital region...

Soil contaminated by polychlorinated biphenyls (PCBs) is a ubiquitous problem in the world, which can cause significant risks to human health and the environment. Mechanochemical destruction (MCD) has been recognized as a promising technology for the destruction of persistent organic pollutants (POPs) and other organic molecules in both solid waste and contaminated soil. However, few studies have been published about the application of MCD technology for the remediation of PCB contaminated soil. In the present study, the feasibility of destroying PCBs in contaminated soil by co-grinding with and without additives in a planetary ball mill was investigated...

The mononuclear Mn(IV)-oxo complex [MnIV(O)(N4py)]2+, where N4py is the pentadentate ligand N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine, has been proposed to attack C-H bonds by an excited-state reactivity pattern [Cho, K.-B.; Shaik, S.; Nam, W., J. Phys. Chem. Lett. 2012, 3, 2851-2856]. In this model, a 4E excited state is utilized to provide a lower-energy barrier for hydrogen-atom transfer. This proposal is intriguing, as it offers both a rationale for the relatively high hydrogen-atom transfer reactivity of [MnIV(O)(N4py)]2+ and a guideline for creating more reactive complexes through ligand modification...

Mononuclear non-heme iron complexes that serve as structural and functional mimics of the thiol dioxygenases (TDOs), cysteine dioxygenase (CDO) and cysteamine dioxygenase (ADO), have been prepared and characterized with crystallographic, spectroscopic, kinetic, and computational methods. The high-spin Fe(II) complexes feature the facially coordinating tris(4,5-diphenyl-1-methylimidazol-2-yl)phosphine ((Ph2)TIP) ligand that replicates the three histidine (3His) triad of the TDO active sites. Further coordination with bidentate l-cysteine ethyl ester (CysOEt) or cysteamine (CysAm) anions yielded five-coordinate (5C) complexes that resemble the substrate-bound forms of CDO and ADO, respectively...
