Understanding the factors that explain the patterns of genetic structure or phylogeographic breaks at an intraspecific level is key to inferring the mechanisms of population differentiation in its early stages. These topics have been well studied in the Baja California region, with vicariance and the dispersal ability of individuals being the prevailing hypothesis for phylogeographic breaks. In this study, we evaluated the phylogeographic patterns in the desert iguana (Dipsosaurus dorsalis), a species with a recent history in the region and spatial variation in life history traits...

Different weight ratios of alginate/gum arabic (GA) solutions were prepared to serve as the wall material of liquid-core hydrogel beads (LHB) that were formulated to protect the total phenolic compounds (TP) of radish by-product juice from degradation during storage and release in simulated gastrointestinal fluid. The diameter of LHB ranged from 4.63 to 5.66mm with a sphericity lower than 0.05. LHB formulated with 25% GA (AGB0.25) exhibited the highest hardness (26.63N), and those formulated with 50% GA (AGB0...

Antimicrobial resistance is one of the most significant health challenges worldwide. Meropenem is a broad spectrum beta-lactam antibiotic that possesses high activity against Gram-positive and Gram-negative bacteria. However, it has a short plasma half-life, and thus requiring frequent administration of high doses. For the first time, meropenem-loaded chitosan nanoparticles were prepared and evaluated as a potential tool to overcome antimicrobial resistance and to improve pharmacokinetics of the drug. Spherical nanosized particles were prepared and demonstrated ultrahigh encapsulation efficiency of meropenem (i...

Skin is a highly plastic tissue that undergoes tissue turnover throughout life, but also in response to injury. YAP and Hedgehog signalling play a central role in the control of epidermal stem/progenitor cells in the skin during embryonic development, in postnatal tissue homeostasis and in skin carcinogenesis. However, the genetic contexts in which they act to control tissue homeostasis remain mostly unresolved. We provide compelling evidence that epidermal YAP and Hedgehog/GLI2 signalling undergo positive regulatory interactions in the control of normal epidermal homeostasis and in basal cell carcinoma (BCC) development, which in the large majority of cases is caused by aberrant Hedgehog signalling activity...

Beginning nursing students typically report anxiety, low self-confidence, and difficulty transferring theoretical knowledge to the clinical setting prior to their first clinical experience. To address these issues, first-semester faculty in a prelicensure, undergraduate nursing program created a collaborative simulation experience (CSE). Implementation prior to the first clinical day provided real-life exposure to patient care, enhanced the transfer of knowledge, decreased anxiety, promoted self-confidence, and allowed faculty to identify students' strengths and weaknesses...

Tube feeding (TF) is the most common form of nutrition support. In recent years, TF administration has increased among patient populations within and outside hospital settings, in part due to greater insurance coverage, reduced use of parenteral nutrition, and improved formularies suitable for sole source nutrition. With increasing life expectancy and improved access to TFs, the number of adults dependent on enteral nutrition is expected to grow. However, enteral TF intolerance (ETFI) is the most common complication of TFs, typically presenting with at least 1 adverse gastrointestinal event, including nausea, diarrhea, and constipation...

End-of-life situations are fraught with challenges for patients, family members, and individuals working at the patient's bedside. Care workers must address needs of the patient, as well as his or her distressed family members. This article is an inductive investigation of care workers' (nurses, patient advocates, and clergy) experiences with end-of-life discussions when the family asks to "do everything." Participants also noted resistance to hospice in some of these encounters based on pre-existing connotations of hospice held by the family members...

Pterin-containing natural products have diverse functions in life but an efficient and easy scheme for their in vitro synthesis is not available. Here, we report a chemo-enzymatic 14-step, one-pot synthesis that can be used to generate 13C- and 15N-labeled dihydrofolates (H2F) from glucose, guanine and p-aminobenzoyl-L-glutamic acid. This synthesis stands out from previous approaches to produce H2F in that the average yield of each step is >91% and it requires only one single purification step. The use of a one-pot reaction allowed us to overcome potential problems with individual steps during the synthesis...

BACKGROUND: Mechanical valve replacement is associated with positive outcomes, but patients must undergo life-long anticoagulation therapy with warfarin, which carries a significant risk of bleeding complications. Therefore, a systematic and continuous assessment and supervision of warfarin treatment is essential in such patients, and approaches that can predict the risk of bleeding in advance are required. The study aim was to develop a classification tool to predict bleeding events in South Korean patients with mechanical valve replacement undergoing oral warfarin therapy...

Infective endocarditis (IE) is a severe disease with high mortality and morbidity. Prosthetic valve endocarditis is a life-threatening complication which can occur in less than 10% of patients with valve prosthesis. A fungal etiology of IE is rare and accounts for only 2-4% of all case of endocarditis, but is associated with a higher mortality and morbidity. Herein is reported the first case of fungal endocarditis of aortic valve prosthesis due to Aspergillus oryzae in a 67-year-old caucasian man who nine years previously underwent mitral and aortic valve replacement with mechanical prostheses, and tricuspid annuloplasty for acute IE due to Enterococcus spp...

Pragmatic trials evaluate interventions in real-life scenarios, which differ from explanatory trials that control for numerous factors and variables to best determine causal associations. Each approach has advantages and disadvantages. Conducting pragmatic research trials while maintaining the tenets of the ethical conduct of research can sometimes be challenging, particularly regarding informed consent. In this column, distinctions between pragmatic and explanatory trials are discussed from an ethical view...
