Allometric models for above-ground biomass, carbon and nutrient content of wild cherry (Prunus avium L.) trees in agroforestry systems

Annals of Forest Science, 2023
Key message We provide a set of allometric models for wild cherry trees (Prunus avium L.) established in agroforestry systems. A total of 70 trees in southwestern Germany were surveyed using terrestrial laser scanning and analysed using quantitative ...

Minipuberty of human infancy – A window of opportunity to evaluate hypogonadism and differences of sex development? [PDF]

Annals of Pediatric Endocrinology & Metabolism, 2020
Activation of the hypothalamic-pituitary-gonadal (HPG) axis happens in 3 phases during life. The first phase is during fetal life and is only separated from the second phase, called minipuberty, by the high concentration of placental hormones at birth ...

Vitamin D Metabolism and Effects on Pluripotency Genes and Cell Differentiation in Testicular Germ Cell Tumors In Vitro and In Vivo

Neoplasia: An International Journal for Oncology Research, 2012
Testicular germ cell tumors (TGCTs) are classified as either seminomas or nonseminomas. Both tumors originate from carcinoma in situ (CIS) cells, which are derived from transformed fetal gonocytes.

Growth and Growth Factors [PDF]

, 2008
The last year has again seen some major advances in the Growth and Growth Factors field. Significant advances have been made in our understanding of the genetics of growth. For example, mutations in the pericentrin gene PCNT are associated with both primordial dwarfism and Seckel syndrome.

Doping dependence of the vortex glass and sublimation transitions in the high-$T_{c}$ superconductor La$_{2-x}$Sr$_{x}$CuO$_{4}$ as determined from macroscopic measurements

, 2004
Magnetization and ac-susceptibility measurements are used to characterize the mixed phase of the high-temperature cuprate superconductor La$_{2-x}$Sr$_{x}$CuO$_{4}$ over a large range of doping (0.075 $\leq x\leq$ 0.20).

USP5-Beclin 1 axis overrides p53-dependent senescence and drives Kras-induced tumorigenicity

Nature Communications, 2022
Oncogene-induced senescence (OIS) occurs in premalignant lung adenomas, but infrequently in malignant adenocarcinomas. Here the authors show that USP5-Beclin 1 axis overcomes OIS in Kras-driven lung cancer by enhancing MDM2-mediated p53 degradation.

Self-Reported Asthma Is Associated with Reduced Sperm Count—A Cross-Sectional Study of More than 6000 Young Men from the General Population

Life, 2023
Asthma is driven by an inflammatory response that may impact testicular function. In this cross-sectional study, we investigated the association between self-reported asthma and testicular function (semen parameters, reproductive hormone levels), and ...

The Impact of Simple Institutions in Experimental Economies with Poverty Traps [PDF]

, 2009
We introduce an experimental approach to study the effect of institutions on economic growth. In each period, agents produce and trade output in a market, and allocate it to consumption and investment.
