Preoperative Echocardiographic Unknown Valvopathy Evaluation in Elderly Patients Undergoing Neuraxial Anesthesia during Major Orthopedic Surgery: A Mono-Centric Retrospective Study.

The assessment of cardiac risk is challenging for elderly patients undergoing major orthopedic surgery with preoperative functional limitations. Currently, no specific cardiac risk scores are available for these critical patients. Echocardiography may be a reliable and safe instrument for assessing cardiac risks in this population.

Identification of HuR-RNA Interfering Compounds by Dynamic Combinatorial Chemistry and Fluorescence Polarization.

The RNA binding protein HuR regulates the post-transcriptional process of different oncogenes and tumor suppressor genes, and its dysregulation is linked with cancer. Thus, modulating the complex HuR-RNA represents a promising anticancer strategy. To search for novel HuR ligands able to interfere with the HuR-RNA complex, the protein-templated dynamic combinatorial chemistry (pt-DCC) method was utilized.

Post-operative oncological and psychological evaluation of patients with colostomy for colorectal cancer.

Background: The therapeutic arsenal for colorectal cancer is largely made up of surgery. In digestive tumors, ostomy devices induce loss of function and control. This medical device generates changes that affect all aspects of patients' lives.

Role of narrow band imaging (NBI), in the treatment of non-polypoid colorectal lesions, with endoscopic mucosal resection (EMR). A single-center experience.

Background: In this study, the authors evaluated the role of narrow band imaging endoscopy in the early detection of infiltration of the colon wall by flat and depressed lesions, highlighted during colonoscopy, to confirm the possibility of removal with Endoscopic Mucosal Resection (EMR).

Methods: 67 patients (37 males and 30 females) with non-polypoid colorectal lesions were included in this study. The location of the lesions, the size and possible infiltration of the colon wall were performed with a colonoscopy with NBI.

Oncological and psychological evaluation of laryngectomized patients, pre and post implantation of voice prostheses. A single center experience.

Background: In our study we evaluated from an oncological and psychological point of view, a group of patients who had previously undergone total laryngectomy and candidates for the placement of a vocal prosthesis, which allows to recover the voice using the air that passes from the trachea to the esophagus, thus vibrating a segment of the cervical esophagus. For the placement of the prosthesis and the oncological follow-up, we used the support of videoendoscopy, to exclude any recurrence or secondary tumors. At the same time, we subjected patients to a psychological evaluation before and after the implantation of the prostheses, to understand the behavioral changes in the two phases, and the possible achievement of the result of total autonomy, social reintegration, and recovery of oral communication, in the post-surgical phase.

Enantiomeric Resolution and Absolute Configuration of a Chiral δ-Lactam, Useful Intermediate for the Synthesis of Bioactive Compounds.

During the past several years, the frequency of discovery of new molecular entities based on γ- or δ-lactam scaffolds has increased continuously. Most of them are characterized by the presence of at least one chiral center. Herein, we present the preparation, isolation and the absolute configuration assignment of enantiomeric 2-(4-bromophenyl)-1-isobutyl-6-oxopiperidin-3-carboxylic acid (-).

BOPC1 Enantiomers Preparation and HuR Interaction Study. From Molecular Modeling to a Curious DEEP-STD NMR Application.

The Hu family of RNA-binding proteins plays a crucial role in post-transcriptional processes; indeed, Hu-RNA complexes are involved in various dysfunctions (i.e., inflammation, neurodegeneration, and cancer) and have been recently proposed as promising therapeutic targets.

Novel Compounds Targeting the RNA-Binding Protein HuR. Structure-Based Design, Synthesis, and Interaction Studies.

The key role of RNA-binding proteins (RBPs) in regulating post-transcriptional processes and their involvement in several pathologies (, cancer and neurodegeneration) have highlighted their potential as therapeutic targets. In this scenario, Embryonic Lethal Abnormal Vision (ELAV) or Hu proteins and their complexes with target mRNAs have been gaining growing attention. Compounds able to modulate the complex stability could constitute an innovative pharmacological strategy for the treatment of numerous diseases.

The use of a microwave-assisted solvent extraction coupled with HPLC-UV/PAD to assess the quality of Marrubium vulgare L. (white horehound) herbal raw material.

Introduction: Marrubium vulgare is a herbal remedy presents in several European Pharmacopoeias and commonly marketed as white horehound. The chemotaxonomic marker of Marrubium genus is marrubiin and its content may change in response to biotic and abiotic stress.

Objective: Development of a microwave-assisted solvent extraction (MASE) methodology suitable for exhaustively extracting marrubiin from M.

Exploration of ligand binding modes towards the identification of compounds targeting HuR: a combined STD-NMR and Molecular Modelling approach.

Post-transcriptional processes have been recognised as pivotal in the control of gene expression, and impairments in RNA processing are reported in several pathologies (i.e., cancer and neurodegeneration).

PKC in Regenerative Therapy: New Insights for Old Targets.

Effective therapies for chronic or non-healing wounds are still lacking. These tissue insults often result in severe clinical complications (i.e.

(R)-(-)-Aloesaponol III 8-Methyl Ether from Eremurus persicus: A Novel Compound against Leishmaniosis.

Leishmaniosis is a neglected tropical disease which affects several millions of people worldwide. The current drug therapies are expensive and often lack efficacy, mainly due to the development of parasite resistance. Hence, there is an urgent need for new drugs effective against infections.

The long story of camptothecin: From traditional medicine to drugs.

20-(S)-Camptothecin (CPT) is a natural alkaloid extracted from the bark of Camptotheca acuminata (Chinese happy tree). It acts as a DNA topoisomerase 1 poison with an interesting antitumor activity and its use is limited by low stability and solubility and unpredictable drug-drug interactions. Since the late 20th century, it has been widely used in cancer therapy and, since extraction yields from plant tissues are very low, various synthetic routes have been developed to satisfy the increase in demand for CPT.

Exploration of the molecular architecture of the orthosteric binding site in the α4β2 nicotinic acetylcholine receptor with analogs of 3-(dimethylamino)butyl dimethylcarbamate (DMABC) and 1-(pyridin-3-yl)-1,4-diazepane.

X-ray crystal structures of acetylcholine binding proteins (AChBPs) have revealed two different possible extensions to the classical ligand binding pocket known to accommodate various nicotinic agonists. One of the pockets is limited in size while the other is of considerable dimensions and protrudes along the interfacial cleft between subunits. To probe these putative extensions in functional nicotinic acetylcholine receptors (nAChRs), elongated analogs of 3-(dimethylamino)butyl dimethylcarbamate (DMABC) and 1-(pyridine-3-yl)-1,4-diazepane were prepared and characterized pharmacologically at neuronal heteromeric nAChRs.
