Evolvability in the fossil record

The concept of evolvability - the capacity of a population to produce and maintain evolutionarily relevant variation - has become increasingly prominent in evolutionary biology. Paleontology has a long history of investigating questions of evolvability, but paleontological thinking has tended to neglect recent discussions, because many tools used in the current evolvability literature are challeng

Conventional agriculture and not drought alters relationships between soil biota and functions

Soil biodiversity constitutes the biological pillars of ecosystem services provided by soils worldwide. Soil life is threatened by intense agricultural management and shifts in climatic conditions as two important global change drivers which are not often jointly studied under field conditions. We addressed the effects of experimental short-term drought over the wheat growing season on soil organi

Compensating for National Socialist Injustice and Indemnifying Jewish Victims

The contribution contains a comprehensive presentation of the legal regulations for the indemnification of National Socialist injustice—notably the restitution of property of Jewish victims of the Holocaust—, using the example of the law of the Federal Republic of Germany. It is also devoted to the contextualization of indemnification and reparation policy in terms of international law, public law

Stimulus-induced EEG-patterns and outcome after cardiac arrest

Objective: EEG is commonly used to predict prognosis in post anoxic coma. We investigated if stimulus-induced rhythmic, periodic or ictal discharges (SIRPIDs) add prognostic information after cardiac arrest. Methods: In the multicenter Targeted Temperature Management trial, routine-EEGs were prospectively recorded after rewarming (≥36 h). Presence and subtype of SIRPIDs and main EEG-pattern (benig

Prevalence, Disease-free, and Overall Survival of Contemporary Patients With Renal Cell Carcinoma Eligible for Adjuvant Checkpoint Inhibitor Trials

Introduction: Designing adjuvant trials is challenging because of uncertainties of prevalence and outcome of high-risk renal cell cancer (RCC) despite use of validated risk scores. Our objective is to investigate how differences in eligibility criteria may impact on potential study results in RCC adjuvant trials. Patients and Methods: RECUR is a multicenter European database capturing patient and

Tungsten oxide quantum dots deposited onto ultrathin CdIn2S4 nanosheets for efficient S-scheme photocatalytic CO2 reduction via cascade charge transfer

A novel S-scheme photocatalytic heterojunction composite nanomaterial is developed by integrating zero-dimensional WO3 quantum dots (WQDs) on two-dimensional ultrathin CdIn2S4 (CIS) nanosheets with the aim of fostering carrier separation, enhancing the performance of carrier interface transport, minimizing carrier distance transport, and achieving effective photocatalytic CO2 reduction. The compos

”Det är ovanligt intressant att vara med i det här kriget”

År 1899 bröt det andra boerkriget ut. Dess koppling till Lunds universitet är kanske inte omedelbart uppenbar, men faktum är att åtminstone en lundastudent begav sig till Sydafrika som frivillig i vad han själv kallade för ett ”ovanligt intressant” krig:Arkivarien vid universitetsarkivet Henrik Ullstad berättar hans historia.

Changes in bone mass associated with obesity and weight loss in humans : Applicability of animal models

The implications of obesity and weight loss for human bone health are not well understood. Although the bone changes associated with weight loss are similar in humans and rodents, that is not the case for obesity. In humans, obesity is generally associated with increased bone mass, an outcome which is exacerbated by advanced age and menopause. In rodents, by contrast, bone mass decreases in propor

Protein tyrosine phosphatase receptor type E (PTPRE) regulates the activation of wild-type KIT and KIT mutants differently

Activation of receptor tyrosine kinases needs tight control by tyrosine phosphatases to keep their normal function. In this study, we investigated the regulation of activation of the type III receptor tyrosine kinase KIT by protein tyrosine phosphatase receptor type E (PTPRE). We found that PTPRE can associate with wild-type KIT and inhibit KIT activation in a dose-dependent manner, although the a

Source contributions in precipitation chemistry and analysis of atmospheric nitrogen deposition in a Sahelian dry savanna site in West Africa

Experimental data on precipitation chemistry were collected at a semi-arid savanna in Senegal (Dahra) in 2013, 2014 and 2017. The chemical composition of precipitation was analyzed for inorganic and organic ions, using ionic chromatography. The pH values of precipitation range from 4.50 to 8.50 with 89% of the samples having basic pH. The composition of precipitation was controlled by four source
