A series of 4-phthalimidobenzenesulfonamide derivatives were designed, synthesized and evaluated for the inhibitory activities against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Structures of the title compounds were confirmed by spectral and elemental analyses. The cholinesterase (ChE) inhibitory activity studies were carried out using Ellman's colorimetric method. The biological activity results revealed that all of the title compounds (except for compound 8) displayed high selectivity against AChE...

Carbonic anhydrases (CAs) III and VII are two cytosolic isoforms of the α-CA family which catalyze the physiological reaction of carbon dioxide hydration to bicarbonate and proton. Despite these two enzymes share a 49% sequence identity and present a very similar three-dimensional structure, they show profound differences when comparing the specific activity for CO2 hydration reaction, with CA VII being much more active than CA III. Recently, CA III and CA VII have been proposed to play a new role as scavenger enzymes in cells where oxidative damage occurs...

Recent advances in stem cell-based regenerative medicine, cell replacement therapy, and genome editing technologies (i.e. CRISPR-Cas 9) have sparked great interest in in vivo cell monitoring. Molecular imaging promises a unique approach to noninvasively monitor cellular and molecular phenomena, including cell survival, migration, proliferation, and even differentiation at the whole organismal level. Several imaging modalities and strategies have been explored for monitoring cell grafts in vivo. We begin this review with an introduction describing the progress in stem cell technology, with a perspective toward cell replacement therapy...

Vegan protein-based diet has attracted increasing interest in the prevention of metabolic syndrome (MetS). Meanwhile, adiponectin has become a highly potential molecular target in the prevention of MetS. Our study will identify a potential vegan protein diet for the prevention of MetS using rat models. Thirty-six Wistar rats were randomly assigned into three groups and given diets containing one of the following proteins for 12 weeks: casein (CAS, control diet), soy protein (SOY), and gluten-soy mixed protein (GSM)...

Preclinical Research Approximately 2,500 years ago, Hippocrates used the word herpes as a medical term to describe lesions that appeared to creep or crawl on the skin, advocating heat as a possible treatment. During the last 50 years, pharmaceutical research has made great strides, and therapeutic options have expanded to include small molecule antiviral agents, protease inhibitors, preventive vaccines for a handful of the papillomaviruses, and even cures for hepatitis C virus infections. However, effective treatments for persistent and recurrent viral infections, particularly the highly prevalent herpesviruses, continue to represent a significant unmet medical need, affecting the majority of the world's population...

Rituximab (RTX) use in open label series has been associated with very encouraging responses in patients with active and moderate-to-severe Graves' Orbitopathy (GO). Recently randomized controlled trials of RTX have been performed in such patients in order to answer the question of clinical efficacy and the safety profile of this agent. That data, reported separately, focused on Clinical Activity Score (CAS) and indicated in one trial a strong benefit of RTX in comparison with IV glucocorticoids while the other trial noted the absence of a benefit by comparison with placebo...

BACKGROUND: With carotid artery stenosis, infarcts can occur in the cortical or internal watershed areas, or both. The timing of carotid artery stenting (CAS) after a cerebral watershed infarction (CWI) is not yet codified. In this retrospective study, we analyzed the safety and clinical effect of early CAS for CWI patients due to carotid artery stenosis. METHODS: Between March 2011 and April 2014, 120 CWI patients with ipsilateral carotid artery stenosis were recruited...

Indigo blue is a natural dye used for thousands of years by civilizations to dye fabric blue and it is naturally obtained from Isatis tinctoria. I. tinctoria is not only used for extraction of indigo blue color but also used medicinally in Traditional Chinese Medicine because of its active compounds. Sodium dithionite (Na2S2O4) is used in dye bath for indigo blue extraction, but this reducing agent and its derivatives are major pollutants of textile industry and subsequently have hazardous influences on public health...

To help develop a comprehensive, quantitative understanding of the hazards of 1,2-dichloroethane (ethylene dichloride, EDC, CAS No. 107-06-2) exposure by the inhalation route, the results of existing subchronic studies and an extended one-generation reproductive toxicity (EOGRT) study recently conducted by the oral route in rats were extrapolated using a physiologically based pharmacokinetic (PBPK) model. The no observed adverse effects levels (NOAELs) for the endpoints of neurotoxicity and reproductive/developmental toxicity were the highest tested doses of 169 and 155 mg/kg-day, respectively...

The existing literature has identified that beliefs about the interpersonal meaning of condom use are a significant predictor of condomless anal sex (CAS). Some have suggested that condom use in this context may function as a form of nonverbal communication. This study utilized attachment theory as a framework and tested a hypothesized model linking adult attachment to CAS through communication skills and condom expectancies. An online survey was completed by 122 single, HIV-negative gay and bisexual (GB) men living in the U...

Diagnosis by MRI is frequently non-trivial due to the low sensitivity of the technique. Signal enhancing contrast agents (CAs) are used to aid in the analysis of MR images. We present here a simple protocol for the preparation of responsive CAs based on Mn nanosheets. Mn nanostructures presented here undergo a chemical and structural change in the presence of altered physiological conditions that activate their signal. This strategy allows for a reduction of background, increasing the sensitivity of the technique...

BACKGROUND: The influence of acute cerebral ischemic lesions (CILs) on the revascularization outcome of symptomatic carotid stenosis has been scarcely investigated in the literature. This study evaluated the effect of CILs and their volume on the results of carotid revascularization in symptomatic patients. METHODS: All patients with symptomatic carotid artery stenosis who underwent carotid endarterectomy (CEA) or carotid artery stenting (CAS) between 2005 and 2014 were considered...

The world's fisheries and aquaculture industries produce vast amounts of protein-containing by-products that can be enzymatically hydrolysed to smaller peptides and possibly be used as additives to functional foods and nutraceuticals targeted for patients with obesity-related metabolic disorders. To investigate the effects of fish protein hydrolysates on markers of metabolic disorders, obese Zucker fa/fa rats consumed diets with 75 % of protein from casein/whey (CAS) and 25 % from herring (HER) or salmon (SAL) protein hydrolysate from rest raw material, or 100 % protein from CAS for 4 weeks...

Purpose: Articulatory control and speech production accuracy were examined in children with childhood apraxia of speech (CAS) and typically developing (TD) controls within a novel word-learning task to better understand the influence of planning and programming deficits in the production of unfamiliar words. Method: Participants included 16 children between the ages of 5 and 6 years (8 CAS, 8 TD). Short- and long-term changes in lip and jaw movement, consonant and vowel accuracy, and token-to-token consistency were measured for 2 novel words that differed in articulatory complexity...

Based on the pharmacological importance of dihydropyrimidine (DHPM) scaffold, substituted DHPMs linked with acetamide linker to substituted aromatic anilines were synthesized and evaluated for their potency as acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors. The good AChE inhibitory activity of 4-dihydropyrimidine-2-thione (4a-h) and 2-amino-1,4-dihyropyrimidines (5a-h) series was observed with compound 4a and 4d identified as the most potent compounds with IC50 values of 0.17±0.01 and 0...

Intimate partner violence (IPV) is a public health problem worldwide. Several factors have been found to be associated with an increased prevalence of IPV, such as substance use. A cross-sectional study was conducted with the aim of determining the prevalence of IPV among women entering Hospital del Mar (Barcelona) for any medical/surgical reason, and who had a diagnosis of substance use disorder. Secondly, it was intended to psychometrically validate the Spanish version of the Hurt, Insulted, Threatened with Harm, Screamed (HITS) questionnaire...
