ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Monitoring Structural Change

Econometrica, 1996
Summary: Contemporary tests for structural change deal with detections of the ``one-shot'' type: given an historical data set of fixed size, these tests are designed to detect a structural break within the data set. Due to the law of the iterated logarithm, one-shot tests cannot be applied to monitor out-of-sample stability each time new data arrive ...

Structural changes in odontodysplasia

Oral Surgery, Oral Medicine, Oral Pathology, 1976
Report is made of a histologic and scanning electron microscopic (SEM) study of teeth affected by odontodysplasia. The enamel was found to be thinner than normal, and the entire surface showed numerous depressions. The prismatic orientation, diameter, and density were found to be normal.

Structure and structural change of the myosin head

Advances in Biophysics, 1991
The ATPase site of myosin was located by three-dimensional electron microscopy using the avidin-biotin system. The site is about 5 nm from the tip of the myosin head, about 4 nm apart from the actin-binding site of myosin. Other functional sites on the myosin head were located by electron microscopy with the avidin-biotin system, monoclonal antibodies ...

Structural change and unemployment

Structural Change and Economic Dynamics, 1990
It is the opening article in a new Journal. The papers presented in the first issue touch on problems that go beyond the short run, they are concerned with the disrupting effects of technical change and of shifts in demand, they represent what is becoming known as structural economic dynamics.

THE DRIVERS OF STRUCTURAL CHANGE

Journal of Economic Surveys, 2018
AbstractThe main goal of this paper is to provide an integrated survey of the literature devoted to identifying the drivers of structural change, broadly defined as the process of reallocation of economic activity across the three broad sectors agriculture, manufacturing and services.

Fine Structural Changes of the Liver.

Annals of Internal Medicine, 1963
Excerpt The fine structural study of the normal and abnormal liver has brought to light many new structures, some that occur in every cell, and others, only erratically.

Structural change, econometrics of

2008
This article covers methodological issues related to estimation, testing and computation for models involving structural changes. The amount of work on this subject since the 1950s is truly voluminous in both the statistics and econometrics literature. Accordingly, any survey is bound to focus on specific aspects.
