Mercury removal from mining wastewater by bioaccumulation and thermal separation in Eichhornia crassipes.

Environmental problems persist due to mercury from artisanal and small-scale gold mining (ASGM) as well as ecological problems associated with the macrophyte Eichhornia crassipes Martius (EC). Environmental problems persist due to mercury contamination from artisanal and small-scale gold mining (ASGM) and ecological issues related to the macrophyte Eichhornia crassipes Martius (EC). A bioaccumulation study was conducted on mercury-laden wastewater (WWm) from ASGM using a pilot treatment plant, specifically a constructed wetland system (CW) with the macrophyte species EC.

Effects of 3-day fasting on secretory IgA concentration in the saliva and lymphotoxin alpha expression in healthy volunteers: a proof of concept study.

Background: animal studies have shown that enteral stimuli play an important role in modulating gut-associated lymphoid tissue.

Objective: the main objectives of this study were 1) to evaluate the effect of 3-day fasting on secretory immunoglobulin A (S-IgA) in parotid saliva and 2) to determine the levels of lymphotoxin (LT) transcription in peripheral blood mononuclear cells (PBMNC) from healthy volunteers as a proxy for studying GALT health.

Methods: these adult volunteers had fasted for three days as part of a cultural ritual.

A pause in the weakening of the Atlantic meridional overturning circulation since the early 2010s.

The current state-of-the-art climate models when combined together suggest that the anthropogenic weakening of the Atlantic Meridional Overturning Circulation (AMOC) has already begun since the mid-1980s. However, continuous direct observational records during the past two decades have shown remarkable resilience of the AMOC. To shed light on this apparent contradiction, here we attempt to attribute the interdecadal variation of the historical AMOC to the anthropogenic and natural signals, by analyzing multiple climate and surface-forced ocean model simulations together with direct observational data.

Assessment of reference evapotranspiration forecasting in the Mediterranean climate of Central Chile using the ASCE standardized Penman-Monteith equation, the Hargreaves-Samani equation, and weather predictions from the Global Forecast System model.

Accurate estimation of crop evapotranspiration (ET) is essential for effective agricultural water resource planning. To determine ET it is common multiplying the reference evapotranspiration (ET) by an appropriate crop coefficient (K). Forecasting ET could be particularly beneficial for irrigation scheduling.

Early outcomes of robotic versus video-thoracoscopic anatomical segmentectomy: a propensity score-matched real-world study.

Objectives: Minimally invasive anatomic segmentectomy for the resection of pulmonary nodules has significantly increased in the last few years. Nevertheless, there is limited evidence on the safety and feasibility of robotic segmentectomy compared to video-assisted thoracic surgery. This study aimed to compare the real-world early outcomes of robotic and video-thoracoscopic surgery in anatomic segmentectomy.

Involvement of aquaporins in Shiga toxin-induced swelling and water transport dysfunction in human renal microvascular endothelial cells.

One of the hallmarks of Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) is kidney damage. Our previous research demonstrated that Shiga toxin type 2 (Stx2a) decreases cell viability and induces swelling of human glomerular endothelial cells (HGEC). However, Stx2a can disrupt net water transport across HGEC monolayers without affecting cell viability.

Posttraumatic Osteomyelitis in Mosul and Gaza: A Retrospective Cohort Study, 2018-2022.

Background: The history of conflicts in the Middle East has resulted in a high burden of complications from conflict-related wounds like posttraumatic osteomyelitis (PTO). This is particularly challenging to manage in settings like Mosul, Iraq and Gaza, Palestine, where healthcare systems are weakened. In nonconflict settings, PTO caused by (PAPTO) can lead to >20% of treatment failures.

The identity of Centrodinium elongatum, type species of the dinoflagellate genus Centrodinium (Dinophyceae), and a review on the synonymy of allied species.

The planktonic dinoflagellate genus Centrodinium has been understudied, with the type species C. elongatum remaining undocumented since the original description. Here, we report C.

An in-silico study of conventional and FLASH radiotherapy iso-effectiveness: potential impact of radiolytic oxygen depletion on tumor growth curves and tumor control probability.

. This work aims to investigate the iso-effectiveness of conventional and FLASH radiotherapy on tumors through in-silico mathematical models. We focused on the role of radiolytic oxygen depletion (ROD), which has been argued as a possible factor to explain the FLASH effect.

Astrocytic Ca activation by chemogenetics mitigates the effect of kainic acid-induced excitotoxicity on the hippocampus.

Astrocytes play a multifaceted role regulating brain glucose metabolism, ion homeostasis, neurotransmitters clearance, and water dynamics being essential in supporting synaptic function. Under different pathological conditions such as brain stroke, epilepsy, and neurodegenerative disorders, excitotoxicity plays a crucial role, however, the contribution of astrocytic activity in protecting neurons from excitotoxicity-induced damage is yet to be fully understood. In this work, we evaluated the effect of astrocytic activation by Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) on brain glucose metabolism in wild-type (WT) mice, and we investigated the effects of sustained astrocyte activation following an insult induced by intrahippocampal (iHPC) kainic acid (KA) injection using 2-deoxy-2-[F]-fluoro-D-glucose (F-FDG) positron emission tomography (PET) imaging, along with behavioral test, nuclear magnetic resonance (NMR) spectroscopy and histochemistry.

Interventional solutions for post-surgical problems: a lymphatic leaks review.

The lymphatic circulation plays a crucial role in maintaining fluid balance and supporting immune responses by returning serum proteins and lipids to the systemic circulation. Lymphatic leaks, though rare, pose significant challenges post-radical neck surgery, oesophagectomy, and thoracic or retroperitoneal oncological resections, leading to heightened morbidity and mortality. Managing lymphatic leaks necessitates consideration of aetiology, severity, and volume of leakage.

Investigating the stability of aromatic carboxylic acids in hydrated magnesium sulfate under UV irradiation to assist detection of organics on Mars.

The Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument onboard the Mars 2020 Perseverance rover detected so far some of the most intense fluorescence signals in association with sulfates analyzing abraded patches of rocks at Jezero crater, Mars. To assess the plausibility of an organic origin of these signals, it is key to understand if organics can survive exposure to ambient Martian UV after exposure by the Perseverance abrasion tool and prior to analysis by SHERLOC. In this work, we investigated the stability of organo-sulfate assemblages under Martian-like UV irradiation and we observed that the spectroscopic features of phthalic and mellitic acid embedded into hydrated magnesium sulfate do not change for UV exposures corresponding to at least 48 Martian sols and, thus, should still be detectable in fluorescence when the SHERLOC analysis takes place, thanks to the photoprotective properties of magnesium sulfate.

Prorocentrum canariense sp. nov., a case of pseudo-cryptic speciation in the cosmopolitan dinoflagellate P. compressum (Prorocentrales, Dinophyceae).

Distributable, metabolic PET reporting of tuberculosis.

Tuberculosis remains a large global disease burden for which treatment regimens are protracted and monitoring of disease activity difficult. Existing detection methods rely almost exclusively on bacterial culture from sputum which limits sampling to organisms on the pulmonary surface. Advances in monitoring tuberculous lesions have utilized the common glucoside [F]FDG, yet lack specificity to the causative pathogen Mycobacterium tuberculosis (Mtb) and so do not directly correlate with pathogen viability.
