Recent Advances on Properties and Utility of Nanomaterials Generated from Industrial and Biological Activities
Today is the era of nanoscience and nanotechnology, which find applications in the field
of medicine, electronics, and environmental remediation. Even though nanotechnology is in its
emerging phase, it continues to provide solutions to numerous challenges. Nanotechnology and
nanoparticles are found to be very effective because of their unique chemical and physical properties
and high surface area, but their high cost is one of the major hurdles to its wider application. So,
the synthesis of nanomaterials, especially 2D nanomaterials from industrial, agricultural, and other
biological activities, could provide a cost-effective technique. The nanomaterials synthesized from
such waste not only minimize pollution, but also provide an eco-friendly approach towards the
utilization of the waste. In the present review work, emphasis has been given to the types of
nanomaterials, different methods for the synthesis of 2D nanomaterials from the waste generated
from industries, agriculture, and their application in electronics, medicine, and catalysis
Validity and reliability of Arabic version of the ID Pain screening questionnaire in the assessment of neuropathic pain
Diagnosis of neuropathic pain (NP) can be challenging. The ID Pain (ID-P) questionnaire, a screening tool for NP, has been used widely both in the original version and translated forms. The aim of this study was to develop an Arabic version of ID-P and assess its validity and reliability in detecting neuropathic pain. The original ID-P was translated in Arabic language and administered to the study population. Reliability of the Arabic version was evaluated by percentage observed agreement, and Cohen’s kappa; and validity by sensitivity, specificity, correctly classified, and receiver operating characteristic (ROC) curve. Physician diagnosis was considered as the gold standard for comparing the diagnostic accuracy. The study included 375 adult patients (153 [40.8%] with NP; 222 [59.2%] with nociceptive pain). Overall observed percentage agreement and Cohen’s kappa were >90% and >0.80, respectively. Median (range) score of ID-P scale was 3 (2–4) and 1 (0–2) in the NP group and NocP group, respectively (p<0.001). Area under the ROC curve was 0.808 (95% CI, 0.764–0.851). For the cut-off value of ≥2, sensitivity was 84.3%, specificity was 66.7%, and correct classification was 73.9%. Thus, the Arabic version of ID-P showed moderate reliability and validity as a pain assessment tool. This article presents the psychometric properties of the Arabic version of ID Pain questionnaire. This Arabic version may serve as a simple yet important screening tool, and help in appropriate management of neuropathic pain, specifically in primary care centers in the Kingdom of Saudi Arabia
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Scallion Peel Mediated Synthesis of Zinc Oxide Nanoparticles and Their Applications as Nano fertilizer and Photocatalyst for Removal of Organic Pollutants from Wastewater
Nanotechnology and nanomaterials have gained much attention in recent years due to their remarkable features. Among nanoparticles, photocatalytic material, such as zinc oxide, have shown tremendous applications in each and every field of science. In the present research, investigators have synthesized zinc oxide nanoparticles (ZnONPs) using Scallion’s peel extract. ZnONPs were both spherical and rod-shaped, where the size for spherical particles was 40–100 nm and rod-shaped, particles size was more than 200 nm as confirmed by microscopic techniques. The typical trademark bands of ZnONPs at 400–800 cm−1 were revealed by infrared spectroscopy, which also showed bands of carbonyl and hydroxyl groups. The hydrodynamic size by particle size analyzer (PSA) shows a size near about 200 nm in diameter. Furthermore, the synthesized ZnONPs were used to assess their potential as a micronutrient for the plant and nano adsorbent for the removal of antibiotics (ampicillin) and methylene blue dye from the simulated wastewater. The antibiotic and dye removal were observed under UV light and visible light against contact time. In comparison to control seeds, seeds grown with ZnONPs have shown better germination and seedling. It could be concluded that ZnONPs acted as an important nanosized source of nutrition for agricultural applications. Thus, the effect of ZnONPs has been proven as a nano-based nutrient source for agricultural purposes. The remediation study found that remediation of both ampicillin and methylene blue dye was efficient under UV light under similar experimental parameters from the simulated wastewater by the ZnONPs

NTIRE 2019 Challenge on Video Deblurring: Methods and Results
This paper reviews the first NTIRE challenge on video deblurring (restoration of rich details and high frequency components from blurred video frames) with focus on the proposed solutions and results. A new REalistic and Di- verse Scenes dataset (REDS) was employed. The challenge was divided into 2 tracks. Track 1 employed dynamic mo- tion blurs while Track 2 had additional MPEG video com- pression artifacts. Each competition had 109 and 93 reg- istered participants. Total 13 teams competed in the final
testing phase. They gauge the state-of-the-art in video de- blurring problem
