Increased radical scavenging activity of thymoquinone and l-ascorbic acid dual encapsulated in palmitoyl-chitosan nanoparticles in a human normal lung fibroblast, MRC-5 due to synergistic antioxidative effects.

Less effective antioxidant supplementation in combating free radicals is often related to the lack of the formulation of carriers. The antioxidant may be one of the most powerful substances but is marred by poor uptake by cells when the carrier degraded and dissolved too rapidly. Nanoparticle (NP) systems are promising in overcoming the problem since they provide high surface area to enhance encapsulation and release efficiency.

Recent advances in advanced oxidation processes (AOPs) for the treatment of nitro- and alkyl-phenolic compounds.

The presence of phenolic compounds in the aquatic environment has posed severe risks due to their toxicity. Among the phenolic families, nitro- and alkyl-phenolic compounds have been categorized as precedence contaminants by the United States Environmental Protection Agency (US EPA). Therefore, efficient treatment methods for wastewater containing nitro- and alkyl-phenolic compounds are urgently needed.

A review on synergistic coexisting pollutants for efficient photocatalytic reaction in wastewater remediation.

With the tremendous development of the economy and industry, the pollution of water is becoming more serious due to the excessive chemical wastes that need to remove thru reduction or oxidation reactions. Simultaneous removal of dual pollutants via photocatalytic redox reaction has been tremendously explored in the last five years due to effective decontamination of pollutants compared to a single pollutants system. In a photocatalysis mechanism, the holes in the valence band can remarkably promote the oxidation of a pollutant.

Malware detection using static analysis in Android: a review of FeCO (features, classification, and obfuscation).

Android is a free open-source operating system (OS), which allows an in-depth understanding of its architecture. Therefore, many manufacturers are utilizing this OS to produce mobile devices (smartphones, smartwatch, and smart glasses) in different brands, including Google Pixel, Motorola, Samsung, and Sony. Notably, the employment of OS leads to a rapid increase in the number of Android users.

Synergistic effect of probe sonication and ionic liquid for extraction of phenolic acids from oak galls.

Phenolic acids of oak gall were extracted using ultrasonic-probe assisted extraction (UPAE) method in the presence of ionic liquid. It was compared with classical ultrasonic-bath assisted extraction (CUBAE) and conventional aqueous extraction (CAE) method, with and without the presence of ionic liquid. Remarkably, the UPAE method yielded two-fold higher extraction yield with the presence of ionic liquid, resulting 481.

Amino modified mesostructured silica nanoparticles for efficient adsorption of methylene blue.

In this work, mesostructured silica nanoparticles (MSN(AP)) with high adsorptivity were prepared by a modification with 3-aminopropyl triethoxysilane (APTES) as a pore expander. The performance of the MSN(AP) was tested by the adsorption of MB in a batch system under varying pH (2-11), adsorbent dosage (0.1-0.

2-Methyl-N-[(3-methyl-2-pyrid-yl)carbamothio-yl]benzamide.

In the title compound, C(15)H(15)N(3)OS, the thio-urea group is stabilized by an intra-molecular hydrogen bond between the carbonyl O atom and the thio-amide group. A C-H⋯N intramolecular hydrogen bond is also present. Mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯S hydrogen bonds.

N-[(2,4-Dimethyl-phen-yl)carbamothio-yl]-2-methyl-benzamide.

The title compound, C(17)H(18)N(2)OS, adopts a trans-cis geometry of the thio-urea group which is stabilized by intra-molecular hydrogen bonds between the O atom of the carbonyl group and the H atom of the thio-amide group. A C-H⋯S intramolecular hydrogen bond is also present. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯S hydrogen bonds to form centrosymmetric dimers.

Nipah virus infection: pathology and pathogenesis of an emerging paramyxoviral zoonosis.

In 1998, an outbreak of acute encephalitis with high mortality rates among pig handlers in Malaysia led to the discovery of a novel paramyxovirus named Nipah virus. A multidisciplinary investigation that included epidemiology, microbiology, molecular biology, and pathology was pivotal in the discovery of this new human infection. Clinical and autopsy findings were derived from a series of 32 fatal human cases of Nipah virus infection.
