#1
Arbind Kumar Choudhary, Etheresia Pretorius
Aspartame is a synthetic dipeptide artificial sweetener, frequently used in foods, medications, and beverages, notably carbonated and powdered soft drinks. Since 1981, when aspartame was first approved by the US Food and Drug Administration, researchers have debated both its recommended safe dosage (40 mg/kg/d) and its general safety to organ systems. This review examines papers published between 2000 and 2016 on both the safe dosage and higher-than-recommended dosages and presents a concise synthesis of current trends...

BACKGROUND: Direct sequencing and amplification refractory mutation system (ARMS) are commonly used to detect epidermal growth factor receptor (EGFR) mutation status in patients with non-small-cell lung cancer to inform the decision-making on tyrosine kinase inhibitors treatment. This study aimed to systematically compare the two methods in terms of the rate of detected mutations and the association of detected mutations with clinical outcomes. MATERIAL AND METHODS: PubMed, EMBASE, China National Knowledge Infrastructure (in Chinese) and Wanfang database (in Chinese) were searched to identify relevant studies...

Pedicularis plants (Orobanchaceae), popularly known as lousewort, are found in Asia, Europe, and North America, and have been used in Sowa-Rigpa, the Himalayan art of healing and a traditional system of medicine for treating various ailments in humans. A comprehensive compilation on this valuable medicinal plant is not available, however. The present extensive review provides insight into the salient medicinal properties of Pedicularis plants with respect to various health issues and diseases. Our previous studies on Pedicularis plants from the Changthang region of Ladakh (India) and research advances leading to new developments in this field have prompted this review...

Mehdi Touat, Daniel Talmasov, Damien Ricard, Dimitri Psimaras
PURPOSE OF REVIEW: Immune-checkpoint inhibitors (ICIs) constitute a novel class of agents recently approved to treat a number of human malignancies. Due to their immunomodulatory mechanism of action, ICIs can generate a wide range of immune-related adverse events (irAEs) of which neurological toxicities are of special interest because of their potential severity. The objective of this review is to examine the recent literature describing neurological irAEs and discuss their optimal management...

Jonathan E Peelle
Everyday conversation frequently includes challenges to the clarity of the acoustic speech signal, including hearing impairment, background noise, and foreign accents. Although an obvious problem is the increased risk of making word identification errors, extracting meaning from a degraded acoustic signal is also cognitively demanding, which contributes to increased listening effort. The concepts of cognitive demand and listening effort are critical in understanding the challenges listeners face in comprehension, which are not fully predicted by audiometric measures...

OBJECTIVE: ABO antigens are highly abundant in many human cell types, including platelets, vascular endothelium, and red blood cells. The presence of a thrombus is associated with adverse clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). We reviewed the relationship between ABO blood groups and thrombus burden in patients with STEMI. PATIENTS AND METHODS: We carried out a retrospective study of 396 patients with STEMI who did not have an ABO blood group or thrombus burden...

BACKGROUND: Substance use disorder (SUD) remains a significant public health issue. A greater understanding of how genes and environment interact to regulate phenotypes comprising SUD will facilitate directed treatments and prevention. METHODS: The literature studying the neurobiological correlates of SUD with a focus on the genetic and environmental influences underlying these mechanisms was reviewed. Results from twin/family, human genetic association, gene-environment interaction, epigenetic literature, phenome-wide association studies are summarized for alcohol, nicotine, cannabinoids, cocaine, and opioids...

OBJECTIVES: This study was aimed at identifying patients with systemic inflammatory response syndrome (SIRS) and determining whether the presence of SIRS on admission was associated with drug resistance and poor outcome in status epilepticus (SE) patients. METHODS: We conducted a prospective review of patients consecutively admitted to two territory centers over a 7-year period. SIRS was considered present if the necessary criteria persisted for 12h. Other potential outcome predictors in a cohort of patients with SE were also collected...

Climate sensitivity represents the global mean temperature change caused by changes in the radiative balance of climate; it is studied for both present/future (actuo) and past (paleo) climate variations, with the former based on instrumental records and/or various types of model simulations. Paleo-estimates are often considered informative for assessments of actuo-climate change caused by anthropogenic greenhouse forcing, but this utility remains debated because of concerns about the impacts of uncertainties, assumptions, and incomplete knowledge about controlling mechanisms in the dynamic climate system, with its multiple interacting feedbacks and their potential dependence on the climate background state...

The world widespread rise in cancer incidence has caused an increase in the demand for effective and safe materials for treatment. One of the most prevalent forms of treatment for cancer is photodynamic therapy (PDT), which is seen as an alternative to radiotherapy, as well as chemotherapy. In more recent years, researchers are exploring new nanotechnology-based strategies to improve the effectiveness of PDT. OBJECTIVE: The objective of this review is to explore the current trends and research findings associated with PDT and the development of nanotechnology as treatment modality for cancer...

BACKGROUND: Femoroacetabular impingement (FAI) can lead to hip pain and early joint degeneration. There have been few reports to date on the outcomes of hip arthroscopy for the treatment of FAI in the military population. Purpose/Hypothesis: The purpose of this study was to compare patient demographics with postoperative outcomes after hip arthroscopy for symptomatic FAI and to identify preoperative risk factors for poor outcomes. The hypothesis was that certain preoperative patient characteristics will be predictive of poorer outcomes and that lower outcomes scores will be associated with a higher likelihood of medical separation from the military...

Through the use of the limited materials palette, optimally designed micro- and nanostructures, and tightly regulated processes, nature demonstrates exquisite control of light-matter interactions at various length scales. In fact, control of light-matter interactions is an important element in the evolutionary arms race and has led to highly engineered optical materials and systems. In this review, we present a detailed summary of various optical effects found in nature with a particular emphasis on the materials and optical design aspects responsible for their optical functionality...
