Article Synopsis
  • Hippocampal sclerosis (HS) is a major cause of temporal lobe epilepsy (TLE) but can be hard to detect on MRI, leading to surgical delays, so researchers created open-source software to improve diagnosis.
  • The study involved 365 participants, using the software HippUnfold to analyze MRI scans and develop a logistic regression model that accurately identifies and localizes HS.
  • The classifier showed high accuracy in detecting HS in both initial and independent patient cohorts, proving effective for individual assessments by comparing patient data with normative growth patterns.

The concrete industry is a significant consumer of drinking water and natural aggregates, such as sand and gravel. However, the scarcity of water and aggregate resources and the challenges associated with the disposal of construction and demolition waste prompted the exploration of alternative materials. This study investigates the feasibility of incorporating secondary treated wastewater from UASB reactors followed by trickling filters and mixed recycled aggregates as potential alternatives.

Introduction: Déjà vu (DV), a French term meaning "already seen," refers to inappropriate sensation of familiarity in the present moment, as if it had been experienced before without a specific recollection of when or where. Traditionally, DV has been closely associated with focal seizures originating from the medial temporal lobe. However, there are occasional reports of DV occurring in idiopathic generalized epilepsies (IGEs).

The integration of green technologies such as microwave- and enzyme-assisted extraction (MEAE) has been shown to improve the extraction efficiency of bioactive compounds while reducing processing time and costs. MEAE using tannase alone (MEAE-Tan), or in combination with cellulase and pectinase (MEAE-Tan-Cel-Pec), was optimized to produce enriched phenolic and antioxidant extracts from olive pomace. The individual and integrated impact of enzyme concentration, temperature, and pomace/water ratio were determined using a central composite rotatable design.

From small seeds falling from trees to asteroids colliding with planets and moons, the impact of projectiles onto granular targets occurs in nature at different scales. In this paper, we investigate open questions in the mechanics of granular cratering, in particular, the forces acting on the projectile and the roles of granular packing, grain-grain friction, and projectile spin. For that, we carried out discrete element method computations of the impact of solid projectiles on a cohesionless granular medium, where we varied the projectile and grain properties (diameter, density, friction, and packing fraction) for different available energies (within relatively small values).

Background: Tinnitus is defined as the subjective perception of sound in the absence of an external stimulus, and tinnitus disorder becomes relevant when it is associated with emotional distress, cognitive dysfunction, and/or autonomic arousal. Hearing loss is recognized as the main risk factor for the pathogenesis of tinnitus. However, clinical guidelines for tinnitus disorder provide little direction for those who have severe-to-profound hearing loss including those who are pre-lingually Deaf.

Hemophilia A and B are hereditary bleeding disorders, characterized by factor VIII or IX deficiencies, respectively. For many decades, prophylaxis with coagulation factor concentrates (replacement therapy) was the standard-of-care approach in hemophilia. Since the 1950s, when prophylaxis started, factor concentrates have been improved with virus inactivation and molecule modification to extend its half-life.

Aims: This study evaluated the association of mucinous metaplasia (MM) with tumor cell proliferation, androgen receptor (AR) expression and invasiveness in Pten conditional knockout mice and the prognostic value of MM markers for patients with PCa.

Main Methods: Prostatic lobes samples from genetic engineered mouse model Pten and Pb-Cre4/Pten were submitted for histopathological analysis and tissue expression of AR, the proliferation marker Ki67, alpha-smooth muscle actin, and laminin. RNAseq data of prostatic lobes samples were analyzed searching for MM gene expression patterns.

Tomato paste production generates a residue known as tomato pomace, which corresponds to peels and seeds separated during tomato processing. Currently, there is an opportunity to use tomato pomace to obtain a functional extract with antithrombotic properties, such as platelet anti-aggregant activity. The aim of this study was to evaluate the yield and inhibitory activity of different extracts of tomato pomace on in vitro platelet aggregation, comparing this activity with commercial cardioprotective products, and quantify bioactive compounds.

Waste management drivers towards a circular economy in the global south - The Colombian case.

Waste Manag

June 2020

FLUXUS, Laboratory on Urban and Socio-Environmental Sustainability Teach Learning, Department of Infrastructure and Environment Studies, School of Civil Engineering, Architecture and Urban Studies, UNICAMP-University of Campinas, Campinas, SP, Brazil.

Circular Economy (CE) turned into one of the most popular topics worldwide for presenting itself as the solution to problems linked to the traditional "take-make-consume-dispose" system. But, how can CE be addressed as public policies worldwide? While there are ambitious and committed strategies in the European Union and Asia, the path that emerging economies are taking is poorly researched. Therefore, we selected Colombia, a Latin American country which is beginning to implement new public policies that are on par with global concerns.

School of Mechanical Engineering, UNICAMP-University of Campinas, Rua Mendeleyev, 200, Campinas, SP, Brazil.

Article Synopsis
  • Barchan dunes are crescent-shaped sand formations found in various environments, characterized by their size variation, from decimeters in water to kilometers on Mars.
  • The study focuses on the growth of subaqueous barchans by numerically reproducing prior experiments, utilizing a combined computational fluid dynamics and discrete element method to simulate their evolution under turbulent water flow.
  • The simulations successfully mirrored experimental results, capturing important measurements like granular flux and forces on individual grains, thus providing new insights into the growth mechanisms of barchan dunes that current experiments have not yet measured.

This study evaluated the influence of the high-intensity ultrasound (HIUS) technology on the quality parameters of a model dairy beverage (chocolate whey beverage), operating under the same energy density (5000 J/mL), but applied at different ways. Two processes were performed varying nominal power and processing time: HIUS-A (160 W and 937 s), and HIUS-B (720 W and 208 s). Our objective was to understand how different modes of application of the same HIUS energy density could influence the microstructure, droplet size distribution, zeta potential, phase separation kinetic, color parameters and mineral profile of the chocolate whey beverage.

To investigate the potential role of immunotherapies in the cellular and molecular mechanisms associated with ovarian cancer (OC), we applied a comparative proteomic toll using protein identification combined with mass spectrometry. Herein, the effects of the protein aggregate magnesium-ammonium phospholinoleate-palmitoleate anhydride, known as P-MAPA, and the human recombinant interleukin-12 (hrIL-12) were tested alone or in combination in human SKOV-3 cells. The doses and period were defined based on a previous study, which showed that 25 μg/mL P-MAPA and 1 ng/mL IL-12 are sufficient to reduce cell metabolism after 48 h.

Immunotherapies have emerged as promising complementary treatments for ovarian cancer (OC), but its effective and direct role on OC cells is unclear. This study examined the combinatory effects of the protein aggregate magnesium-ammonium phospholinoleate-palmitoleate anhydride, known as P-MAPA, and the human recombinant interleukin-12 (hrIL-12) on cell migration/invasion, apoptosis, toll-like receptor (TLR)-mediated inflammation, and cytokine/chemokine profile in human OC cell line SKOV-3. P-MAPA and IL-12 showed cancer cell toxicity under low doses after 48 h.
