G-Quadruplexes: Emerging Anticancer Roles
G-quadruplexes, a family of (thermodynamically and kinetically stable) tetraplex helices, are non-canonical secondary structures derived from guanine (G)-rich sequences of nucleic acids. G-quadruplexes were found to occur in functionally-important regions of the human genome, including the telomere tandem sequences, several proto-oncogene promoters and other regulatory regions, ribosomal DNA (rDNA), as well as mRNA sequences encoding for proteins with roles in tumorigenesis, thus establishing a clear connection between G-quadruplexes and known hallmarks of cancer. Stabilization of G-quadruplexes belonging to the above categories, by means of small-molecule intervention, has been correlated with a range of anticancer effects, which has led to classifying G-quadruplexes as novel potential targets in anticancer research. The most common ways in which G-quadruplexes are now understood to serve in an anticancer capacity are presented herein.

The Role of Hormones in Hidradenitis Suppurativa
Hidradenitis suppurativa (HS) is a chronic inflammatory disease manifesting in inverse body regions. In HS, there appears to be a dysregulated adipokine release that is shifted towards pro-inflammatory adipokines. Insulin resistance is significantly more common in HS than in healthy patients regardless of BMI, age, and gender. Insulin resistance in HS patients leads to further cardiovascular disease. The mechanism of insulin resistance and role of adipokines should be investigated in future studies to better provide the pathomechanisms of HS. The role of androgens seems to be important in a certain subgroup of female patients. Anti-androgenic therapy can be useful and helpful in some patients.

Articular Eminence and Temporomandibular Disorders
In order to determine the correlation between the inclination of articular eminence (AEI) and the development of temporomandibular disorders (TMDs), a systematic review was performed.

Citrus-Derived Polymethoxylated Flavones
Several reports have shown that polymethoxylated flavones (PMFs) derived from citrus fruit, such as nobiletin, tangeretin, and 3,3′,4′,5,6,7,8-heptamethoxyflavone, are promising molecules for the prevention of neurodegenerative and neurological disorders. In various animal models, PMFs have been shown to have a neuroprotective effect and improve cognitive dysfunction with regard to neurological disorders by exerting favorable effects against their pathological features, including oxidative stress, neuroinflammation, neurodegeneration, and synaptic dysfunction as well as its related mechanisms.

Fusion Imaging (CT/MRI–CEUS) in Oncology
Fusion imaging depicts an innovative technique by which previously performed computed tomography/magnetic resonance imaging can be integrated and reconstructed with advanced contrast-enhanced ultrasound using modern ultrasound devices in a real-time manner. Fusion imaging allows for complementing strengths and reducing restrictions of the combined imaging modalities. The visualization of parenchymal and tumoral microperfusion by contrast-enhanced ultrasound can be dynamically fused and assessed with images from previous cross-sectional studies and may help to decipher underlying entities of indeterminate lesions or validate suspicious morphology. The findings from our study demonstrate the benefits of fusion imaging for evaluating focal hepatic and renal lesions. The excellent safety profile, accessibility, repeatability and cost-effectiveness are advantages of fusion imaging which make it a powerful diagnostic tool for the modern radiologist.

Lindera Obtusiloba
Lindera, a core genus containing more than 100 species, is a member of the Litseeae tribe under the Lauraceae family. Plants of the Lindera genus are widely distributed all over the world, particularly in the tropical, subtropical and temperate regions of Asia and midwestern America. Plants from the Lindera genus are considered a rich source of essential oils and are often used in the production of aromatic cosmetic products such as soap and lubricants for their elegant fragrance. Most importantly, throughout history, many Lindera plants have been used in traditional medicine for their healing and curing capabilities for several health-related implications, such as pain, cold, urinary tract disorders, rheumatoid arthritis, gastric ulcer, abdominal pain, cholera, and beriberi.

Astaxanthin on Human Skin Ageing
Skin ageing is becoming a global challenge due to longer human longevity and intensive ultra-violet rays contributed to the ozone layer destruction, attracting greater scientific interests in developing nutricoesmetic products, especially from natural functional ingredients with lower side-effects. Astaxanthin, a carotenoid with high antioxidant and anti-inflammatory effects, which could be extracted from the byproduct of processed crustaceans, prevented skin photoaging and age-related skin diseases in the animal models. But these byproducts are generally discarded as marine waste, losing potentially valuable ingredients, and causing serious environmental problems by accumulating high amounts of organic materials. ASX may have cosmetical potential to prevent or reverse human skin ageing, which has been evaluated in several previous papers. Here, we conducted a systemic review and meta-analysis to help clarify its human skincare effects, which promote marine waste recycling, environmental protection, and sustainable development.

Bland–Altman Agreement Analysis
The Bland–Altman Limits of Agreement is a popular and widespread means of analyzing the agreement of two methods, instruments, or raters in quantitative outcomes. An agreement analysis could be reported as a stand-alone research article but it is more often conducted as a minor quality assurance project in a subgroup of patients, as a part of a larger diagnostic accuracy study, clinical trial, or epidemiological survey. Consequently, such an analysis is often limited to brief descriptions in the main report. Therefore, in several medical fields, it has been recommended to report specific items related to the Bland–Altman analysis. Seven proposals were identified from a MEDLINE/PubMed search on March 03, 2020, three of which were derived by reviewing anesthesia journals. Broad consensus was seen for the a priori establishment of acceptability benchmarks, estimation of repeatability of measurements, description of the data structure, visual assessment of the normality and homogeneity assumption, and plotting and numerically reporting both bias and the Bland–Altman Limits of Agreement, including respective 95% confidence intervals. Abu-Arafeh et al. provided the most comprehensive and prudent list, identifying 13 key items for reporting (Br. J. Anaesth. 2016, 117, 569–575). The 13 key items should be applied by researchers, journal editors, and reviewers in the future, to increase the quality of reporting Bland–Altman agreement analyses.

MRS in Hepatic Fat
Magnetic resonance spectroscopy (MRS) is a powerful tool that allows direct quantification of metabolites in tissue or areas of interest. MRS has been applied in both research and clinical studies to assess liver fat noninvasively in vivo. MRS has also demonstrated excellent performance in liver fat assessment with high sensitivity and specificity compared to biopsy and other imaging modalities. Because of these qualities, MRS has been generally accepted as the reference standard for the noninvasive measurement of liver steatosis. MRS is an evolving technique with high potential as a diagnostic tool in the clinical setting.
