Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

Ferritin level prospectively predicts hepatocarcinogenesis in patients with chronic hepatitis B virus infection [PDF]

, 2018
Previous studies have detected a higher level of ferritin in patients with hepatocellular carcinoma (HCC), but a potential causal association between serum ferritin level and hepatocarcinogenesis remains to be clarified.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Chronic hyperplastic anemia as an independent risk factor for atherosclerotic lesions: a lesson from thalassemia intermedia [PDF]

, 2010
Introduction. Cardiovascular involvement represents a well-known complication and the primary cause of mortality, both in transfusion-dependent beta thalassemia major (β-TM) and in transfusion-independent beta thalassemia intermedia (β-TI ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

N‐terminal pro‐brain natriuretic peptide and cardiorenal outcome in patients with anaemia in chronic kidney disease

ESC Heart Failure, Volume 12, Issue 2, Page 848-858, April 2025.
Abstract Aims Blood levels of N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) may be modified by low renal clearance and anaemia. The aim of this study was to investigate the impact of the blood NT‐proBNP level on cardiovascular and renal outcomes in patients with these two manifestations.

Recurrent BMP4 variants in exon 4 cause non-HFE-associated hemochromatosis via the BMP/SMAD signaling pathway

Orphanet Journal of Rare Diseases
Background Hereditary hemochromatosis (HH) is an iron overload disorder and can be caused by variants in non-HFE genes in Chinese patients. However, there is still a considerable proportion of patients suffering from unexplained iron overload.

Implementation of guideline‐recommended medical therapy for patients with heart failure in Europe

ESC Heart Failure, Volume 12, Issue 2, Page 790-798, April 2025.
Abstract Physicians' adherence to guideline‐recommended heart failure (HF) treatment remains suboptimal, especially regarding the target doses. In particular, there is evidence that non‐cardiologists are less compliant with HF guideline recommendations. This is likely to have a detrimental impact on patients' survival, readmissions and quality of life.

Iron body stores in patients treated with red-cell transfusions

Zdravniški Vestnik, 2007
Background: Consequence of chronic transfusion therapy is a secondary iron overload, which adversely affects the heart, liver and endocrine glands. This can be minimized by iron chelating therapy.
