Aerobic granules were cultivated in sequencing batch reactor (SBR) by feeding 2,4-dinitrotoluene (2,4-DNT) along with acetate. Aerobic granules with an SVI10 of 34.57 ± 2.6 mL g−1 and average diameter of 0.78 ± 0.3 mm were formed during 30 d of SBR start-up period. In an alternative approach, ...
As a major intermediate in the synthesis of explosives, the destructive nature and thermal hazards of 2,4-DNT are enormous. To evaluate the potential thermal hazards for its decomposition, the differential scanning calorimeter (DSC) experiments under non-isothermal and isothermal conditions were...
Over the past century, rapid growth of population, mining and industrialization significantly contributed to extensive soil, air and water contamination. The 2,4-dinitrotoluene (2,4-DNT), used mostly as explosive, belongs to the hazardous xenobiotics. Soils and waters contaminated with 2,4-DNT m...
Fe-Mn binary oxides (FMBOs) with different molar ratios of Fe and Mn (1:1–8:1) synthesized in a redox-precipitation method were investigated for the activation of a combination of persulfate (PS) and hydrogen peroxide (HP) for the degradation of 2,4-dinitrotoluene (2,4-DNT). X-ray diffraction a...
Optimum conditions have been determined for the immobilization of glucoamylase on glass involving diazotized 5-aminosalicylic acid bonded to a deposited imperfectly crystallized film of TiO2. The changes in the kinetic and thermodynamic characteristics of the enzyme on immobilization have been d...
SUMMARYRash diseases characterized macules, papules, vesicles and pustules. Many viral infection associated with generalized morbilliform skin rash. Papular purpuric gloves and socks syndrome (PPGSS) is a clinical situation caused by human parvovirus B19. PPGSS occurs at hands and foot through l...
Purpuric pigmented dermatoses represent a form of chronic, recurrent capillaritis characterized by petechiae and purpuric macules over the lower limbs. We report three female cases who presented with clinical features of purpuric pigmented dermatosis with unusual histopathologic features. The fi...
BackgroundPapular-purpuric gloves-and-socks syndrome, characterized by focal acral purpuric eruptions with a symmetrical distribution, is a rare but representative purpuric dermatosis closely associated with parvovirus B19 (PVB19) infection. However, several atypical presentations such as involv...
Clopidogrel is an adenosine diphosphate receptor antagonist used for the prevention of vascular events in patients with atherothrombotic diseases manifested by recent myocardial infarction, ischemic stroke or peripheral arterial disease. Diarrhoea, rash and pruritus are rather common side effect...
BackgroundThe purpose of this report is to demonstrate the clinical effect of Korean medicine treatment for pigmented purpuric dermatosis (PPD).
Hemorrhagic rashes are observed in a wide variety of conditions, ranging from harmless to life threatening. This review offers a stepwise approach, which helps limit the possible differential diagnoses on the basis of the symptoms and the clinical picture. The most common and most important cond...
Induction of hepatic microsomal cytochrome P450 produced by carbamic acid [[2,6-bis(1-methylethyl)phenoxy]sulfonyl]-2,6-bis(1-methylethyl) phenyl ester, monosodium salt (PD138142-15), a novel water-soluble inhibitor of acyl-CoA:cholesterol acyltransferase, was examined in male and female rats, d...
A procedure has been developed for determining N-(1-methylethyl)-N′-phenyl-1,4-benzenediamine in urine by using high-performance liquid chromatography. The method uses chloroform extraction for partial clean-up of the urine sample. The separation is carried out on a reversed-phase column using ...
Butadiene (BD) has been copolymerized with methyl methacrylate (MMA) using as initiator 13C-enriched samples of either azobisisobutyronitrile at 60°C or 1,1′-azobis(1-phenylethane) (APE) at 100°C. The initiator fragments in the copolymers have been examined by 13C-NMR and the numbers attached...
Standard molar enthalpies of formation of 1-methylethyl, (CH3)2CHNH3X, n-butyl, CH3(CH2)3NH3X and 2-methylpropyl, (CH3)2CHCH2NH3X, ammonium halides (X=Cl, Br, I) have been determined by solution-reaction calorimetry at 298.15±0.02 K. Heat capacities for solid and liquid phases were determined f...
Atrazine is an herbicide which has shown potential antimalarial effects both in vitro and in vivo in rats. In order to study the metabolism of atrazine in rat livers, we developed a sensitive LC/MS/MS method for the identification of atrazine and several of its metabolites. Using this method, we...
As part of our ongoing efforts to develop reversible inhibitors of LSD1, we identified a series of 4-(pyrrolidin-3-yl)benzonitrile derivatives that act as successful scaffold-hops of the literature inhibitor GSK-690. The most active compound, 21g, demonstrated a Kd value of 22 nM and a biochemic...
The clandestine synthesis of ring and side chain modified phenylisopropylamines continues to be a major source of these drugs of abuse. One method used for the synthesis of the amphetamine and related compounds involves the treatment of the appropriate ketone with formamide or ammonium formate f...
Suzuki–Miyaura cross-coupling reaction with 2-heteroarylboronic acids is generally challenging due to these acids easy decomposition. To overcome this problem, we developed a coupling method that uses 2-heteroaryl pinacol boronates in the presence of 1.0 mol % Pd(OAc)2 and 2.0 mol % S-Phos with...
Tumors still remain one of the main causes of mortality due to the lack of effective anti-cancer therapy. Recently it has been shown, that overexpression of inducible cyclooxygenase-2 (COX-2) and decrease of peroxisome proliferator-activated receptor γ (PPARγ) expression accompany many maligna...
