Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Life expectancy is the death-weighted average of the reciprocal of the survival-specific force of mortality

Demographic Research, 2010
The hazard of mortality is usually presented as a function of age, but can be defined as a function of the fraction of survivors. This definition enables us to derive new relationships for life expectancy.

Biology and population growth parameters of jasmine whitefly, Aleuroclava jasmini on four different orange cultivars [PDF]

نامه انجمن حشره‌شناسی ایران, 2015
Biology and population growth parameters of Jasmine whitefly, Aleuroclava jasmini (Takahashi) were studied on four orange cultivars including Siavaraz, Valensia, Mars and Washangton under laboratory conditions (27 ± 1 oC, 60 ± 5% RH and 14: 10 h L: D ...

Impact of hexythiazox on life table parameters of the Amblyseius swirskii (Acari: Phytoseiidae) and its prey Tetranychus urticae

Journal of Crop Protection, 2021
The two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most important and destructive herbivorous mites in farm and greenhouse that has developed high levels of resistance to many acaricides.

Labor market transitions of young women over the early life course: A multistate life table analysis [PDF]

Using detailed panel data on school, work, and family formation history of youth (i.e., NLSY 1979-1991), we examine the dynamic process of labor market transitions women make during young adulthood. Transitions between the states of the labor force (i.e.,

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Effects of temperatures on the development and reproduction of the armyworm, Mythimna roseilinea: Analysis using an age-stage, two-sex life table

Journal of Integrative Agriculture, 2018
The armyworm Mythimna roseilinea (Walker) is a major pest of grain crops in South China. So far little is known about its basic biology and ecology, making prediction of population dynamics difficult.

Ages of origin and destination for a difference in life expectancy [PDF]

Decomposition of a difference in life expectancies may identify ages at which the difference originates in mortality differences, or may identify age at which the difference results in different values of person-years lived (life table population).
