Cyanopeptides occurrence and diversity in a brazilian tropical reservoir: exploring relationships with water quality
This study aimed (i) to determine the dynamics of MCs and other cyanopeptides in a tropical reservoir, (ii) to investigate the correlation between peptides and potential cyanotoxin producers (iii) identifying the possible abiotic factors that influence the peptides. We analyzed, monthly, eight MC variants (MC-RR, -LA, -LF, -LR, -LW, -YR, [D-Asp3]-RR and [D-Asp3]-LR) and other peptides in 47 water samples collected monthly, all season long, from two sampling sites in a tropical eutrophic freshwater reservoir, in southeastern Brazil. The cyanopeptides were assessed by liquid chromatography-tandem mass spectrometry (LC-MS/MS)...

Exceptionally high levels of total mercury in deep-sea sharks of the Southeastern Mediterranean sea over the last ∼ 40 years
Environ Int. 2024 Apr 15;187:108661. doi: 10.1016/j.envint.2024.108661. Online ahead of print.ABSTRACTDeep-sea habitats are currently recognized as a hot spot for mercury (Hg) accumulation from anthropogenic sources, resulting in elevated concentrations of total mercury (THg) in deep-sea megafauna. Among them, deep-sea sharks (Class Chondrichthyes) are characterized by high trophic position and extended longevity and are, therefore, at high risk for mercury contamination. Despite this, sharks are overexploited by fishing activity in increasingly deeper water, worldwide, imposing health risks to human consumption. While it ...

Importance of methodological pluralism in deriving counterfactuals for evidence-based conservation
Conserv Biol. 2024 Apr 30:e14285. doi: 10.1111/cobi.14285. Online ahead of print.ABSTRACTMost protected area impact research that uses counterfactuals draws heavily on quantitative methods, data, and knowledge types, making it valuable in producing generalizations but limited in temporal scope, historical detail, and habitat diversity and coverage of ecosystem services. We devised a methodological pluralistic approach, which supports social science qualitative methods, narratives, mixed methods, and interdisciplinarity, to fully unlock the potential of counterfactuals in ensuring a place-based and detailed understanding of...

Limb Ischemic Necrosis Secondary to Microvascular Thrombosis: A Brief Historical Review
Semin Thromb Hemost DOI: 10.1055/s-0044-1786356Ischemic limb injury can be broadly classified into arterial (absent pulses) and venous/microvascular (detectable pulses); the latter can be divided into two overlapping disorders—venous limb gangrene (VLG) and symmetrical peripheral gangrene (SPG). Both VLG and SPG feature predominant acral (distal) extremity ischemic necrosis, although in some instances, concomitant nonacral ischemia/skin necrosis occurs. Historically, for coagulopathic disorders with prominent nonacral ischemic necrosis, clinician-scientists implicated depletion of natural anticoagulants, especially invol...

Sensors, Vol. 24, Pages 2860: In Situ Test and Numerical Analysis of the Subway-Induced Vibration Influence in Historical and Cultural Reserves
This study investigates the spatial distribution characteristics of vibration in the Fayuan Temple historic and cultural reserve. It involves using a V001 magnetoelectric acceleration sensor capable of monitoring low amplitudes with a sensitivity of 0.298 V/(m/s2), a measuring range of up to 20 m/s2, and a frequency range span from 0.5 to 100 Hz for in situ testing, analyzing the law of vibration propagation in this area, evaluating the impact on buildings, and determining the vibration reduction scheme. The reserve is divided into three zones based on the vertical vibration level measured during the in situ test as follow...

Stephen T. Magill
Meningioma classification and treatment have evolved over the past eight decades. Since Bailey, Cushing, and Eisenhart’s description of meningiomas in the 1920s and 1930s, there have been continual advances in clinical stratification by histopathology, radiography and, most recently, molecular profiling, to improve prognostication and predict response to therapy. Precise and accurate classification is essential to optimizing management for patients with meningioma, which involves surveillance imaging, surgery, primary or adjuvant radiotherapy, and consideration for clinical trials....

Clinical and laboratory features of sickle cell disease s/d punjab: impact of hbf and hydroxyurea
Conclusion: SD Punjab is the third most common SCD genotype in Oman and was associated with recurrent VOC, ACS, AVN, and gall stones comparable to other SCD genotypes. Patients with> 3 VOC/year had significantly increased incidence of Stroke, AVN, and gallstones. However, HU was not associated with improved prognosis and better survival in this cohort of patients.Keywords: Sickle Cell Disease; Haemoglobin SD Punjab; vaso-occlusive crises; acute chest syndrome; Avascular Necrosis; HbF; hydroxyurea.

Disulfidptosis decoded: a journey through cell death mysteries, regulatory networks, disease paradigms and future directions
Biomark Res. 2024 Apr 29;12(1):45. doi: 10.1186/s40364-024-00593-x.ABSTRACTCell death is an important part of the life cycle, serving as a foundation for both the orderly development and the maintenance of physiological equilibrium within organisms. This process is fundamental, as it eliminates senescent, impaired, or aberrant cells while also promoting tissue regeneration and immunological responses. A novel paradigm of programmed cell death, known as disulfidptosis, has recently emerged in the scientific circle. Disulfidptosis is defined as the accumulation of cystine by cancer cells with high expression of the solute ca...
