[The Rezūm system in the treatment of male lower urinary tract symptoms (LUTSs) due to benign prostatic obstruction (BPO)].

Aktuelle Urol 2018 Dec 6;49(6):519-524. Epub 2018 Dec 6.

Spital Thurgau AG, Urologie, Frauenfeld.

The classical algorithm of the management of male lower urinary tract symptoms (LUTSs) due to benign prostatic hyperplasia (BPH) includes a surgical approach in case pharmacological therapy has failed. Emerging minimally-invasive treatments (MITs) offer potential for rapid symptomatic relief, reducing the morbidity of invasive BPH surgery. Convective interstitial radiofrequency water vapour thermal ablation of the prostate with the Rezūm system is a novel MIT for the treatment of bothersome moderate-to-severe lower urinary tract symptoms associated with BPH.

Instituto Mexicano del Seguro Social, Hospital de Especialidades “Dr. Bernardo Sepúlveda Gutiérrez”, Unidad de Investigación Médica en Endocrinología Experimental. Ciudad de México, México

More than 70% of the population in Mexico is overweight or obese, affecting mainly people in productive age. Obesity is associated with the development of diseases that increase cardiovascular risk (diabetes mellitus, hypertension or atherogenic dyslipidemia), diseases that limit the quality of life of the patient (osteoarthrosis or sleep apnea) and even with the increase in the incidence of certain types of cancer (breast or colon). It is evident that the decrease of at least 5% of body weight induces improvement in all these factors; however, in some patients it is difficult to achieve this goal only with lifestyle modifications.

Insight into Amorphous Solid Dispersion Performance by Coupled Dissolution and Membrane Mass Transfer Measurements.

Mol Pharm 2018 Dec 6. Epub 2018 Dec 6.

The tendency of highly supersaturated solutions of poorly water soluble drugs to undergo liquid-liquid phase separation (LLPS) into drug-rich and water-rich phases when the concentration exceeds the amorphous solubility, for example, during dissolution of some amorphous solid dispersions, is thought to be advantageous from a bioavailability enhancement perspective. Recently, we have developed a high surface area, flow-through absorptive dissolution testing apparatus that enables fast mass transfer providing more in vivo relevant conditions and time frames for formulation testing. Using this apparatus, the absorption behaviors of solutions with different extents of supersaturation below and above the amorphous solubility were evaluated. Read More

Alzheimer's disease (AD) is well-known as a severe neurodegeneration disease involving complicated etiologies, and cholinesterase inhibition remain the prevailing mode of clinical intervention in AD management. Although most clinically applied cholinesterase inhibitors (ChEIs) achieve limited clinical outcomes, research on the central cholinergic system is still thriving. Recently, an impressive amount of knowledge regarding novel acetylcholinesterase functions, as well as the close association between the central cholinergic system and other key elements for AD pathogenesis, has accumulated, highlighting that this field still has great potential for future drug development.

Aromatic Nitrogen Mustard-Based Autofluorescent Amphiphilic Brush Copolymer as pH-Responsive Drug Delivery Vehicle.

Biomacromolecules 2018 Dec 6. Epub 2018 Dec 6.

Delivery of clinically approved nonfluorescent drugs is facing challenges because it is difficult to monitor the intracellular drug delivery without incorporating any integrated fluorescence moiety into the drug carrier. The present investigation reports the synthesis of a pH-responsive autofluorescent polymeric nano-scaffold for the administration of nonfluorescent aromatic nitrogen mustard chlorambucil (CBL) drug into the cancer cells. Copolymerization of poly(ethylene glycol) (PEG) appended styrene and CBL conjugated N-substituted maleimide monomers enables the formation of well-defined luminescent alternating copolymer.

Annotation of the Giardia proteome through structure-based homology and machine learning.

Gigascience 2018 Dec 6. Epub 2018 Dec 6.

Walter & Eliza Hall Institute of Medical Research, Melbourne, Australia.

Background: Large-scale computational prediction of protein structures represents a cost-effective alternative to empirical structure determination with particular promise for non-model organisms and neglected pathogens. Conventional sequence-based tools are insufficient to annotate the genomes of such divergent biological systems. Conversely, protein structure tolerates substantial variation in primary amino acid sequence, and is thus a robust indicator of biochemical function. Read More
