OBJECTIVE The anti-malarial drug, artemisinin, is harvested from the leaves of adult Artemisia annua L. plants. As its concentration in juvenile plants is very low, the present study aimed to assess if the airborne signaling molecule, β-ocimene, could be used to enhance artemisinin accumulation in juvenile A. annua plants. RESULTS Application of exogenous β-ocimene increased artemisinin accumulation in A. annua. Treatment with 10 µM β-ocimene for 4 days resulted in juvenile plants accumulating artemisinin contents of up to 25 mg/g (2.5%) of dry weight. The expression levels of key genes encoding enzymes involved in both precursor biosynthetic pathways and artemisinin biosynthetic pathways induced by β-ocimene were upregulated. Glandular secretory trichome (GST) size and density increased by 49.2% and 38.2%, respectively, along with the upregulation of genes associated with GST development. CONCLUSION β-ocimene enhances artemisinin accumulation in juvenile A. annua plants by modulating artemisinin biosynthetic pathways and GST development.PURPOSE To correct a potentially damaging mutation in haploid human embryonic stem cells. METHODS Exome sequencing was performed on DNA extracted from parthenogenetically derived embryonic stem cell line (pES12). An SLC10A2 gene mutation, which affects bile acid transport, was chosen as mutation of interest in this proof of concept study to attempt correction in human pluripotent haploid cells. Confirmation of the mutation was verified, and guide RNA and a correction template was designed in preparation of performing CRISPR. Haploid cells underwent serial fluorescence activated cell sorting (FACS) with Hoechst 33342 to create an increasingly haploid (1n) enriched culture. Nucleofection was performed on p. 37 and then cells were sorted for 1n DNA content with +GFP to identify the haploid cells that expressed Cas9 tagged with GFP. RESULTS 104,686 haploid GFP + cells were collected. Cells were cultured, individual colonies picked, and 48 clones were sent for Sanger sequencing. CRIPSR efficiency was 77.1%, with 7/48 (14.6%) clones resulting in a corrected SLC10A2 mutation. Confirmation of persistence of haploid cells was achieved with repeated FACS sorting and centromere quantification. Given the large number of passages and exposure to CRISPR, we also performed analysis of karyotypes and of off-target effects. Cells evaluated were karyotypically normal and there was no evident off target effects. CONCLUSIONS CRISPR/Cas9 can be effectively utilized to edit mutations in haploid human embryonic stem cells. Establishment and maintenance of a haploid cell culture provides a novel way to utilize CRISPR/Cas9 in gene editing, particularly in the study of recessive alleles.PURPOSE To examine the time of removal of the odontogenic focus, antibiotic therapy and risk factors in odontogenic abscesses. PATIENTS From January 2012 to December 2015, inpatients undergoing incision due to odontogenic abscesses were identified in a retrospective study. All the patients were evaluated for time of removal of the odontogenic focus, antibiotic therapy, germ spectrum, complications and risk factors. THAL-SNS-032 CDK inhibitor RESULTS Two hundred ten patients completed the study. In 89 cases (42.4%), the odontogenic focus was removed as part of the abscess treatment (group A). In 121 cases (57.6%), the focus was secondarily removed (group B). On average, 2 ± 4 teeth were removed in group A, and 6 ± 5 teeth in group B (p less then  0.0001). An average of 1.2 ± 0.4 surgical interventions were performed in group A, and 2 ± 0.2 operations in group B (p less then  0.0001). Microbiological examination was positive in one-third of the cases (70 cases). Most commonly, streptococci (27%) were isolated. A resistance screening was possible in 57 of the detected germs (68.7%). In 89% of these patients, the combination of ampicillin-sulbactam was effective. The hospital stay was 4.8 ± 2 days for group A and 7.6 ± 3 days for group B (p less then  0.0001). The clinical evaluation revealed 12 intermediate (5.7%) and three long-term (1.4%) complications. The long-term complications included a recurrence in two cases (1%) and an osteomyelitis in one case (0.5%). A logistic regression analysis identified no significant risk factor in relation to these complications. CONCLUSION The study shows that a primary removal of the odontogenic focus may have advantages over a secondary removal (1) fewer operations, (2) shorter hospital stay and (3) shorter antibiotic therapy. Broad-spectrum penicillins in combination with beta-lactamase inhibitors are a possible, sufficient antibiotic regimen. Long-term complications are rare. No risk factors are identified in relation to these complications.PURPOSE To assess the success rate and complications of sialendoscopy and sialolithotripsy for parotid sialolithiasis. MATERIALS AND METHODS A total of 228 articles were identified by the electronic database search regarding the topics sialendoscopy and sialolithotripsy. Following independent then joint review of titles and abstracts, 109 articles were selected for the full review. Thirteen of these were chosen for data extraction from which 1285 patients with parotid salivary stones were identified. Extracted data included number of patients, age, gender, location, management, and outcomes. RESULTS All articles combined, 1285 patients with parotid salivary stones were included with a successful treatment in 1139 patients. The success rated ranged from 71.4 to 100% with a mean of 88.7%. Both partial as complete success was achieved. Although minor complications were frequent, no major complications occurred. CONCLUSIONS Sialendoscopy and sialolithotripsy are best suited as first choice treatment-if conservative therapy failed-for the management of parotid gland sialolithiasis. It is a valuable and feasible treatment option with no major complications. Selection of cases will ensure the best prognosis. Although there is no indefinite stone size, the smaller the calculus, the greater the probability of a symptom-free patient.Plant molecular breeding is expected to give significant gains in cultivar development through development and utilization of suitable molecular marker systems for genetic diversity analysis, rapid DNA fingerprinting, identification of true hybrids, trait mapping and marker-assisted selection. Transposable elements (TEs) are the most abundant component in a genome and being used as genetic markers in the plant molecular breeding. Here, we review on the high copious transposable element belonging to class-II DNA TEs called "miniature inverted-repeat transposable elements" (MITEs). MITEs are ubiquitous, short and non-autonomous DNA transposable elements which have a tendency to insert into genes and genic regions have paved a way for the development of functional DNA marker systems in plant genomes. This review summarises the characteristics of MITEs, principles and methodologies for development of MITEs based DNA markers, bioinformatics tools and resources for plant MITE discovery and their utilization in crop improvement.The intricate physiology of many Central Nervous System (CNS) disorders points towards oxidative damages of neurons. Various studies have established that oxidative stress is a big threat to integrity of neurons. All the sections of central nervous system are exposed to free radicals and charged species formed during oxidative degradation of catecholamines and polyunsaturated fatty acids which are present abundantly in CNS. By products of other biochemical reactions also contribute to oxidative stress in central nervous system. If these charged species are not counter neutralized by antioxidants, it leads to neurodegenerative disorders like Alzheimer's disease, Parkinson's disease, Amyotropic lateral sclerosis, Multiple sclerosis, Spinal cord injury, Schizophrenia etc. The level of charged species and free radicals is found to be higher in neurodegenerative diseases than normal physiological condition and it is related to oxidative damages to neuronal cells. In many of such cases, use of antioxidants decreases oxidative stress and contribute to neuroprotection. This review intends to compile approach of managing oxidative stress in various neurodegenerative disorders. The perspective of this review is to study antioxidants and their role in neuroprotection.The deterioration of the skin morphology and physiology is the first and earliest obvious harbinger of the aging process which is progressively manifested with increasing age. Such deterioration affects the vital functions of the skin such as homeodynamic regulation of body temperature, fluid balance, loss of electrolytes and proteins, production of vitamin D, waste removal, immune surveillance, sensory perception, and protection of other organs against deleterious environmental factors. There are, however, harmful chemicals and toxins found in everyday cosmetics that consumers are now aware of. Thus, the natural beauty industry is on the rise with innovative technology and high-performance ingredients as more consumers demand healthier options. Therefore, the aims of this review are to give some critical insights to the effects of both intrinsic and extrinsic factors on excessive or premature skin aging and to elaborate on the relevance of natural beauty and natural anti-aging skincare approaches that will help consumers, scientists and entrepreneurs make the switch. Our recent investigations have shown the potential and relevance of identifying more resources from our rich natural heritage from various plant sources such as leaves, fruits, pomace, seeds, flowers, twigs and so on which can be explored for natural anti-aging skincare product formulations. These trending narratives have started to gain traction among researchers and consumers owing to the sustainability concern and impact of synthetic ingredients on human health and the environment. The natural anti-aging ingredients, which basically follow hormetic pathways, are potentially useful as moisturizing agents; barrier repair agents; antioxidants, vitamins, hydroxy acids, skin lightening agents, anti-inflammatory ingredients, and sunblock ingredients.BACKGROUND Wide-area transepithelial sampling of the esophagus with computer-assisted three-dimensional analysis (WATS3D, CDx Diagnostics, Suffern, NY) is an adjunctive technique to random biopsies for early detection of Barrett's esophagus. The aim of the SAGES Technology and Value Assessment Committee aims is to evaluate the efficacy, value, and safety of WATS3D. METHODS Clinical studies involving WATS3D were identified via a search of the PubMed/Medline databases (www.ncbi.nlm.nih.gov/pubmed) conducted in March of 2019 using search terms, such as wide-area transepithelial sampling, three-dimensional (3D) computer-assisted analysis, WATS-3D, Barrett's esophagus and WATS-3D, Barrett's esophagus and wide-area transepithelial sampling with three-dimensional computer-assisted analysis, Barrett's esophagus, and emerging technology. Bibliographies of key references were searched for relevant studies not covered by the PubMed search. Case reports and small case series were excluded. RESULTS No significant morbidity or mortality was reported within the literature associated with the WATS3D technology.
