Application of seismogram synthesis to the study of earthquake source from strong motion records

Annals of Geophysics, 1994
We present the results of an analysis of the Michoacan and Landers earthquakes to constrain the kinematic description of the rupture process. The example of the Michoacan earthquake shows that a crack type model is better a dislocation model to describe ...

Petal Senescence: New Concepts for Ageing Cells [PDF]

, 2009
Senescence in flower petals can be regarded as a form of programmed cell death (PCD), being a process where cells or tissues are broken down in an orderly and predictable manner, whereby nutrients are re-used by other cells, tissues or plant parts.

Rupture dimensions and rupture processes of fluid-induced microcracks in salt rock

Journal of Volcanology and Geothermal Research, 2001
Abstract We developed and applied a simple empirical Green function method to study induced microcracks observed during hydraulic fracturing experiments in salt rock. Either unidirectional ruptures on rectangular faults or allround ruptures on elliptical faults are tested to explain the observed directivity effects in body-wave amplitude spectra ...

Productive RUPture: activation of transcription factors by proteasomal processing

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2004
Proteasomes usually degrade proteins completely into small peptides. In a few cases, however, proteasomal degradation rather results in protein processing, thereby yielding proteins of different biological activity. This process, termed "regulated ubiquitin/proteasome-dependent processing" or RUP, is essential for the function of certain transcription ...

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Rupture Process of the Mw7.0 December 5, 2024 Offshore Cape Mendocino Earthquake

Geophysical Research Letters
The Mw7.0 December 5, 2024 Offshore Cape Mendocino earthquake ruptured a ∼60 km long portion of the east‐west trending Mendocino fault zone (MFZ). In order to clarify the rupture process, we assemble three‐component seismograms from regional seismic ...

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Spontaneous splenic rupture 1 week after laparoscopic appendectomy due to acute appendicitis

Journal of Minimal Access Surgery, 2020
Spontaneous splenic rupture is a rare entity that requires high index of suspicion for diagnosis. Usually, it occurs due to underlying pathology that could be inflammatory, neoplastic or infectious.

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.
