When the heart and tumours intertwine: pulmonary hypertension associated with a neuroendocrine tumour-a case report.

Background: Pulmonary hypertension caused by extrinsic pulmonary vascular compression secondary to mediastinal neuroendocrine tumours is a very rare condition, posing a diagnostic challenge. There is no clear consensus regarding the best treatment strategy due to the lack of clinical data, leading to poor prognoses for these patients.

Case Summary: We present the case of a 38-year-old man hospitalized with signs of pulmonary hypertension and acute heart failure.

[Position statement on the use of amlodipine during pregnancy. Working Group on Hypertension in Women, Argentine Society of Hypertension].

Pharmacological management of HDP includes agents supported by extensive evidence ensuring their safety for use. Among those traditionally described in the literature are: alpha-methyldopa, labetalol, and sustained-release nifedipine (NIF-RETARD). These drugs, in addition to being compatible with pregnancy, present additional eligibility criteria.

Evaluating efflux pump inhibition in Staphylococcus aureus 1199B strain using thiadiazine-derived compounds: In vitro and in silico approaches.

Thiadiazines are heterocyclic compounds known for some pharmacological activities. However, the ability of these compounds and their derivatives to act as antibacterial agents and inhibitors of the efflux system in resistant bacteria remains unknown. This study aims to evaluate the antibacterial and NorA efflux pump inhibitory activities of thiadiazine-derived compounds (IJ14, IJ15, IJ16, IJ17, IJ18, IJ19, and IJ20) against the Staphylococcus aureus 1199B strain.

LPDE biodegradation promoted by a novel additive based on silica nanoparticles: Structural, microbial and ecotoxicological characterization.

This study developed a biodegrading additive based on nanosilica and modified by cellulase enzyme in the presence of citric acid and sodium citrate. The additive was tested as a facilitator for biodegradation of the commercial low-density polyethylene (LDPE) in soil. Enzyme immobilization was confirmed by enzymatic assays.

Lifespan longitudinal changes in mesocortical thickness and executive function: Role of dopaminergic genetic predisposition.

Dopamine (DA) signaling is critical for optimal cognitive aging, especially in prefrontal-parietal and fronto-striatal networks. Single nucleotide polymorphisms associated with dopamine regulation, COMTVal158Met and DRD2C957T, stand to exert influence on executive function performance via neural properties. The current study investigated whether longitudinal thinning of mesocortical regions is related to COMT and DRD2 genetic predisposition and associated with decline in executive function over four-years.

ATP-binding cassette transporters and drug resistance in cutaneous leishmaniasis.

Leishmania spp. are intracellular protozoan parasites causative of visceral and cutaneous leishmaniasis. Recognized as a neglected tropical disease affecting millions of people around the world, this affliction represents a major public health problem.

Irreversible electroporation for prostate cancer: another promising focal therapy.

Radical treatment for prostate cancer is associated with significant morbidity. Percutaneous image-guided irreversible electroporation is a non-thermal ablative technique that has emerged as a valuable option. This study describes the case of a patient with prostate cancer who was successfully treated using irreversible electroporation.

Sustained immune activation and impaired epithelial barrier integrity in the ectocervix of women with chronic HIV infection.

Chronic systemic immune activation significantly influences human immunodeficiency virus (HIV) disease progression. Despite evidence of a pro-inflammatory environment in the genital tract of HIV-infected women, comprehensive investigations into cervical tissue from this region remain limited. Similarly, the consequences of chronic HIV infection on the integrity of the female genital epithelium are poorly understood, despite its importance in HIV transmission and replication.

Students and Faculty Experiences, Perceptions and Knowledge on Distress during the COVID-19 Pandemic: A Descriptive Cross-sectional Study.

Background And Objective: The University of the Philippines Manila (UPM) subcommittee on students in distress was convened during the COVID-19 pandemic to develop "plans, programs and mechanisms" to deal with students experiencing distress and mental health concerns. This study was conducted as one of the activities of the Subcommittee to inform policy to address the following research objective: to describe the experiences, perceptions, and knowledge of both students and faculty members of UP Manila regarding distress.

Methods: An online survey tool was created using the results from seven online focus group discussions among 20 faculty of UP Manila.

Liposomal formulation with thiazolic compounds against bacterial efflux pumps.

This study aimed to evaluate the effects of liposome-encapsulated eugenol-based thiazolic derivatives against efflux pump-carrying bacteria. The Minimum Inhibitory Concentration (MIC) was determined to evaluate the antibacterial activity and antibiotic potentiation against Pseudomonas aeruginosa and Staphylococcus aureus, as well as to analyze the inhibition of efflux pumps in S. aureus strains 1199B and K2068 in the ethidium bromide assay.

Thiazine-derived compounds in inhibiting efflux pump in Staphylococcus aureus K2068, mepA gene expression, and membrane permeability alteration.

Staphylococcus aureus is a bacterium responsible for resistance to multiple drugs and the efflux system is widely studied among the resistance mechanisms developed by this species. The present study evaluates the inhibition of the MepA efflux pump by thiadiazine-derived compounds. For this purpose, thiadiazine-derived compounds (IJ-14 to IJ-20) were tested against S.

Occurrence and potential ecological risks of PFAS in Pampulha Lake, Brazil, a UNESCO world heritage site.

Per- and polyfluoroalkyl substances (PFAS) comprise >4000 synthetic substances used in industrial applications and consumer products. PFAS used daily in households and manufacturing plants end up in domestic sewage, and industrial effluents can be discharged to surface water. Urban watersheds located in low and middle-income countries (LMIC), which lack sanitation infrastructure, are potential recipients of waste containing PFAS.

Clinical profiles and treatment outcomes of outpatients with interstitial lung disease and mechanic's hands: A retrospective and observational cohort.

Idiopathic inflammatory myopathies, especially antisynthetase syndrome, often appear outside of the muscles as interstitial lung disease (ILD). Another typical finding is the presence of mechanic's hands. The aim of the present study was to describe the clinical, functional, tomographic, and serological data of patients with ILD and mechanic's hands and their response to treatment and survival rates.

Piezo regulates epithelial topology and promotes precision in organ size control.

Mechanosensitive Piezo channels regulate cell division, cell extrusion, and cell death. However, systems-level functions of Piezo in regulating organogenesis remain poorly understood. Here, we demonstrate that Piezo controls epithelial cell topology to ensure precise organ growth by integrating live-imaging experiments with pharmacological and genetic perturbations and computational modeling.

An Experimental Parametric Optimisation for Laser Engraving and Texturing to Integrate Zirconia Ceramic Blocks into Stainless Steel Cutlery: A State-of-the-Art Aesthetically Improved Perspective.

Cutlery and flatware designs are an everchanging phenomenon of the manufacturing industry. Worldwide hospitality businesses demand perpetual evolution in terms of aesthetics, designs, patterns, colours, and materials due to customers' demands, modernisation, and fierce competition. To thrive in this competitive market, modern fabrication techniques must be flexible, adoptive, fast, and cost effective.

Screening of 152 Veterinary Drug Residues in Animal Source Foods by LC-MS/MS, Multilaboratory Validation Study: Final Action 2020.04.

Background: The presence of veterinary drug residues in food-producing animals and animal products is regulated through the enforcement of maximum residue limits (MRLs). To answer the need of the food sector to monitor these substances in a wide range of food commodities, stakeholders at AOAC INTERNATIONAL identified the need for a reliable confirmatory screening method. Such a qualitative approach is required for compliance checking and to support product release in manufacturing.

Prophylactic Use of Biologic Mesh in Ileal Conduit (PUBMIC): A Randomized Clinical Trial.
