Susana Costas, Óscar Ferreira, Theocharis A Plomaritis, Eduardo Leorri
The uncertainties surrounding present and future sea-level rise have revived the debate around sea-level changes through the deglaciation and mid- to late Holocene, from which arises a need for high-quality reconstructions of regional sea level. Here, we explore the stratigraphy of a sandy barrier to identify the best sea-level indicators and provide a new sea-level reconstruction for the central Portuguese coast over the past 6.5 ka. The selected indicators represent morphological features extracted from coastal barrier stratigraphy, beach berm and dune-beach contact...

Professionalism is rarely taught formally. It is learned by osmosis through the hidden curriculum: a set of attitudes that each one of us transmits unconsciously to students, medical residents, and colleagues. All of us are a model or counter-model of professionalism through a series of values that have been the pillars of our profession since Hippocrates. Values that do not seem to be strong enough to pass our time. There are specific factors of the 21st century such as the financial crisis, the highly technical nature of medicine, bureaucratisation or trivialisation of the medical process that could explain, but not justify, the decline in the values of our profession: Empathy, integrity, solidarity, the altruism, or confidentiality...

Products that are manufactured for use in a clinical trial, with the intent of gaining US Food and Drug Administration (FDA) approval for clinical use, must be produced under an FDA approved investigational new drug (IND) application. We describe work done toward generating reliable methodology and materials for preserving ovarian cortical tissue through a vitrification kit and reviving this tissue through a warming and recovery kit. We have described the critical steps, procedures, and environments for manufacturing products with the intent of submitting an IND...

This review provides a historical overview of the research on plant ribosome-inactivating proteins (RIPs), starting from the first studies at the end of eighteenth century involving the purification of abrin and ricin, as well as the immunological experiments of Paul Erlich. Interest in these plant toxins was revived in 1970 by the observation of their anticancer activity, which has given rise to a large amount of research contributing to the development of various scientific fields. Biochemistry analyses succeeded in identifying the enzymatic activity of RIPs and allowed for a better understanding of the ribosomal machinery...

The indications for delaying the start of dialysis have revived interest in low-protein diets (LPDs). In this observational prospective study, we enrolled all patients with chronic kidney disease (CKD) who followed a moderately restricted LPD in 2007-2015 in a nephrology unit in Italy: 449 patients, 847 years of observation. At the start of the diet, the median glomerular filtration rate (GFR) was 20 mL/min, the median age was 70, the median Charlson Index was 7. Standardized mortality rates for the "on-diet" population were significantly lower than for patients on dialysis (United States Renal Data System (USRDS): 0...

We report the construction of a non-toxic nanoassembly of bovine serum albumin (BSA) protein and the cucurbit[7]uril macrocycle as well as its stimuli-responsive breakage with adamantylamine or pH, which restores the protein structure and recognition properties. The assembly showed efficient loading and controlled release of a standard drug, doxorubicin (DOX), and the same was validated in live cells. The cell viability studies documented that the DOX-loaded assembly mask the cytotoxicity of DOX and the toxicity can be revived at the target on demand, triggering its therapeutic activation...

Theoretical studies are reported for the statistical properties of a microwave-driven interacting magnon system. Both the magnetic dipole-dipole and the exchange interactions are included and the theory is developed for the case of parallel pumping allowing for the inclusion of the nonlinear processes due to the four-magnon interactions. The method of second quantization is used to transform the total Hamiltonian from spin operators to boson creation and annihilation operators. By using the coherent magnon state representation we have studied the magnon occupation number and the statistical behavior of the system...

Retrograde intubation is an invaluable technique which can be helpful in anticipated difficult airway situation. In this advanced era where fiberoptic intubation and video laryngoscopes are in abundant use, retrograde intubation is a forgotten technique. However, it may be useful in various difficult airway situations in this advanced era. In our case the patient had a bitter experience with previous fiberoptic intubation. Owing to that we had planned and performed a fiber optic guided retrograde intubation, where we had kept the fiberoptic bronchoscope in the pharynx keeping larynx and vocal cords in the focus to facilitate the emergence of guide wire through one of the nostrils as well as direct visual confirmation of intubation...

An azobenzene scaffold serves as both a fluorescence quencher and nitrogen mustard deactivator in a mitochondrial targeting unit bearing theranostic drug delivery system (DDS). The DDS exhibited a tissue selectivity for tumors with aggressive phenotypes, and the efficient in vitro and in vivo azoreduction under hypoxia conditions resulted in bright fluorescence at the tumor site as well as the in situ activation of the prodrug. In vivo therapeutic experiments demonstrated a significant reduction in tumor growth versus number of controls and ex vivo tissue analysis confirmed tissue normalization with strongly reduced angiogenic markers and suppressed cell proliferation...

PURPOSE OF REVIEW: In the era of increasing antibiotic resistance worldwide, this review highlights the advantages of revival of old antibiotics for treatment of uncomplicated urinary tract infections (uUTIs). RECENT FINDINGS: Recent studies have shown that these four oral old antibiotics, fosfomycin trometamol, nitrofurantoin, nitroxoline and pivmecillinam, show no increasing antibiotic resistance against uropathogens causing uUTI, are still effective for the treatment of uUTI and exhibit only minimal or no collateral damage as compared with fluoroquinolones or third-generation cephalosporines...

Confronting the storm of carbapenemase-producing Gram-negative pathogens and thus facing the threat of untreatable infections, the medical community revived colistin. Not long since its re-introduction and despite the fact that resistance to colistin at least in Escherichia coli is rare, chromosomally-mediated colistin resistance in metallo-β-lactamase-producing Klebsiella pneumoniae strains was reported in 2004 from Greece. Subsequent studies revealed the highest predominance in Italy (38%) and Greece (26%), with colistin-resistant (Col-R) strains frequently carrying a carbapenemase...

In this contribution to the theme issue recognizing prof. Florence's achievements as editor -in-chief of the Int. J. Pharmaceutics, we analyze the future of pharmacy preparations (also known as extemporaneous preparations or compounded products). Pharmacy preparations, long considered as an endangered part of the pharmacy profession on its way to extinction, may be at the brink of a revival. Drivers of this revival are a set of changes related to new clinical concepts and supply shortages. Moreover, new production and IT paradigms are being developed that facilitate the preparation processes and provide the necessary quality management systems...

CONTEXT: Heroin use in the US has exploded in recent years, and heroin overdoses requiring naloxone are very common. After awakening, some heroin users refuse further treatment or transport to the hospital. These patients may be at risk for recurrent respiratory depression or pulmonary edema. In those transported to the emergency department, the duration of the observation period is controversial. Additionally, non-medical first responders and lay bystanders can administer naloxone for heroin and opioid overdoses...
