Malformations of cortical development (MCD) are a common cause of intractable seizures in humans. Among these, focal cortical dysplasia (FCD) poses an outstanding challenge. There are several subtypes of FCD that show significant variation in pathology and clinical presentation. All types exhibit disturbed cortical cytoarchitecture and increased propensity for seizures. The etiology is likely heterogenous, with mutations, specifically in genes related to mammalian target of rapamycin (mTOR), identified in only a subset of cases...

Fatty liver is a widespread disease in chickens that causes a decrease in egg production and even death. The characteristics of the inherited phenotype of acquired fatty liver and the molecular mechanisms underlying it, however, are largely unknown. In the current study, fatty liver was induced in 3 breeds by a high-fat (HF) diet and a methionine choline-deficient (MCD) diet. The results showed that the dwarf Jingxing-Huang (JXH) chicken was more susceptible to fatty liver compared with the layer White Leghorns (WL) and local Beijing-You (BJY) breeds...

The paper provides a complex, critical assessment of heavy metal soil pollution using different indices. Pollution indices are widely considered a useful tool for the comprehensive evaluation of the degree of contamination. Moreover, they can have a great importance in the assessment of soil quality and the prediction of future ecosystem sustainability, especially in the case of farmlands. Eighteen indices previously described by several authors (Igeo , PI, EF, Cf , PIsum , PINemerow , PLI, PIave , PIVector , PIN, MEC, CSI, MERMQ, Cdeg , RI, mCd and ExF) as well as the newly published Biogeochemical Index (BGI) were compared...

Detailed studies of iron speciation and mechanism in iron-catalyzed cross-coupling reactions are critical for providing the necessary fundamental insight to drive new reaction development. However, such insight is challenging to obtain due to the prevalence of mixtures of unstable, paramagnetic organoiron species that can form in this chemistry. A physical-inorganic research approach combining freeze-trapped inorganic spectroscopic studies, organometallic synthesis and GC/kinetic studies provides a powerful method for studying such systems...

The P-cluster of the nitrogenase MoFe protein is a [ Fe8 S7 ] cluster that mediates efficient transfer of electrons to the active site for substrate reduction. Arguably the most complex homometallic FeS cluster found in nature, the biosynthetic mechanism of the P-cluster is of considerable theoretical and synthetic interest to chemists and biochemists alike. Previous studies have revealed a biphasic assembly mechanism of the two P-clusters in the MoFe protein upon incubation with Fe protein and ATP, in which the first P-cluster is formed through fast fusion of a pair of [ Fe4 S4 ]+ clusters within 5 min and the second P-cluster is formed through slow fusion of the second pair of [ Fe4 S4 ]+ clusters in a period of 2 h...

Mechanochemical degradation (MCD) is a promising eco-friendly method to dispose persistent organic pollutants (POPs). Mechanically induced free-radical attack was thought to be one of the key elements in initiating and accelerating the dechlorination and degradation of POPs. In this study, mechanochemical formation of free-radicals and their roles in the remediation of hexachlorobenzene (HCB) contaminated soil were explored using both of experimental analysis and quantum chemical calculations. It was found that chlorinated phenoxy radicals(CB-O) can be produced in the milling process and they played a vital role in the dechlorination of HCB, based on the results of electron spin-resonance (ESR) and X-ray photoelectron spectra (XPS)...

Multicentric Castleman disease (MCD) is a rare nonmalignant lymphoproliferative disorder presenting systemic symptoms such as fever, night sweats, fatigue, anemia, effusions, and multifocal lymphadenopathy. The etiology of MCD has not been clarified to date. The coexistence of MCD with chronic myelomonocytic leukemia (CMML) has been rarely reported. Although the pathogenesis remains unclear, this association probably reflects an incidental and fortuitous finding rather than the alteration of a common pluripotent stem cell precursor...

Macular corneal dystrophy (MCD) is a corneal stromal dystrophy which leads to progressive vision loss. MCD is an autosomal recessive condition in which there is abnormality of proteoglycan synthesis. Mutations in the carbohydrate sulphotransferase gene (CHST6) prevent normal sulfation of corneal keratan. Different immunophenotypes have been described depending on the presence of keratan sulfate in cornea and or serum. The deposition of abnormal proteoglycans leads to loss of corneal transparency and decreased vision...

Pediatric Castleman disease (CD) is an uncommon and poorly understood disorder of the lymph nodes. Renal failure has not been described in pediatric multicentric CD (MCD). We report four cases, who presented with polyadenopathy, organomegaly, edema and fluid accumulations, high blood pressure, and acute renal failure. In all cases, renal biopsy confirmed diffuse thrombotic microangiopathy. Definitive diagnosis of MCD was made by a biopsy of an affected lymph node located by computer tomography before initiation of corticosteroid therapy...

The ocular bioavailability of lipophilic drugs, such as dexamethasone, depends on both drug water solubility and mucoadhesion/permeation. Cyclodextrins and chitosan are frequently employed to either improve drug solubility or prolong drug contact onto mucosae, respectively. Although the covalent conjugation of cyclodextrin and chitosan brings to mucoadhesive drug complexes, their water solubility is restricted to acidic pHs. This paper describes a straightforward grafting of methyl-β-cyclodextrin (MCD) on quaternary ammonium chitosan (QA-Ch60), mediated by hexamethylene diisocyanate...

We have developed a new coastal database for the Mediterranean basin that is intended for coastal impact and adaptation assessment to sea-level rise and associated hazards on a regional scale. The data structure of the database relies on a linear representation of the coast with associated spatial assessment units. Using information on coastal morphology, human settlements and administrative boundaries, we have divided the Mediterranean coast into 13 900 coastal assessment units. To these units we have spatially attributed 160 parameters on the characteristics of the natural and socio-economic subsystems, such as extreme sea levels, vertical land movement and number of people exposed to sea-level rise and extreme sea levels...

Multicentric Castleman's disease (MCD) is a rare kind of lymphoproliferative disorder characterized by systemic problems such as frequent fever, fatigue and weight loss with angiofollicular lymph node hyperplasia. However, unlike unicentric Castleman's disease (UCD) with long-time survival by surgery and local radiotherapy, MCD remains poor prognosis due to no well-defined optimal treatment strategies and high risk of developing malignances especially lymphoma. We reported a case of MCD who received chemotherapy by ECHOP with unsatisfactory outcome and then oral administration with thalidomide combined with prednisone without disease progression after therapy...

BACKGROUND: The level of urinary cluster of differentiation 80 (uCD80) is elevated in most children with minimal change disease (MCD) as opposed to focal segmental glomerulosclerosis (FSGS) during the acute phase. The objective of this follow-up study was to evaluate whether uCD80 elevation is actually associated with MCD and whether it signals better prognosis. METHODS: We evaluated uCD80 levels and a series of putative progression factors in a cohort of 64 patients with nephrotic syndrome (NS) seen between 2011 and 2016...

The first Si(IV) corrole complexes were synthesized in good yields, for the first time, by treatment of meso-triarylcorroles with tetrachlorosilane in 1,2-dichloroethane at 60 °C. The central silicon atom possesses a square-pyramidal coordination geometry with slightly longer Si-N bond lengths as compared with those of known triazacorrole Si(IV) complexes. The Si(IV) corrole complexes exhibit sharp and blue-shifted absorption spectra and larger fluorescence quantum yields as compared with the corresponding freebase corroles...
