The role of cholesterol differs in the two compartments of the testis. In the interstitial tissue, cholesterol is necessary for the synthesis of testosterone, whereas in the seminiferous tubules, membrane cholesterol content in developing germ cells will influence the gametes' fertility. Here we evaluate the hormone-sensitive lipase (HSL) modulation of the cholesterol metabolism in each compartmen
The present work reports on testicular hormone-sensitive lipase (HSL), the biological significance of which has been documented in male fertility. The HSL protein levels and enzymatic activity were measured, respectively, by densitometry of immunoreactive bands in Western blots, performed with antibodies against recombinant rat HSL, and by spectrophotometry in seminiferous tubules (STf) and inters
Twenty-six children in 3rd grade were observed while surfing freely on their favourite websites. Eye movement data were recorded, as well as synchronized screen recordings. Each online advert was analyzed in order to quantify low-level saliency features, such as motion, luminance and edge density. The eye movement data were used to register if the children had attended to the online adverts. A mix
Simultaneous contact allergies are common in individuals with photocontact allergy to ketoprofen. The rate of contact allergy to the fragrance substances oxidized linalool and oxidized limonene in ketoprofen-photo-allergic individuals were investigated in comparison with the corresponding rates in individuals without photo-contact allergy to ketoprofen, using Fisher's exact test. A total of 4,021
Fossil fuel companies’ existence is incompatible with the planet’s survival, says Bill McKibben Paris 2015 will be one step along the line, not the thing that solves all the problemsWe now have solutions we didn’t have 25 years ago, we should deploy them with all possible speed
The extent to which humans help each other is extraordinary in itself, and difficult to explain from an evolutionary perspective. Therefore, there has been a recent surge in studies investigating the evolution of prosocial behavior using a comparative approach. Nevertheless, most of these studies have focused on primates only, and little is known about other animal orders. In a previous study, com
Background: Long-term outcomes of patients admitted to intensive care units (ICUs) after surgery are unknown. We investigated the long-term effects of surgical exposure prior to ICU admission. Methods: Registry-based cohort study. The adjusted effect of surgical exposure for mortality was examined using Cox regression. Secondary analysis with conditional logistic regression in a case-control subpo
Bacteria are key organisms in energy and nutrient cycles, and predicting the effects of temperature change on bacterial activity is important in assessing global change effects. A changing in situ temperature will affect the temperature adaptation of bacterial growth in lake water, both long term in response to global change, and short term in response to seasonal variations. The rate of adaptatio
This paper evaluates the history and cycling accessibility of Nova, a shopping centre established in Lund, Sweden, in 2002. The current situation was also analysed through observation and a literature review. Moreover, the study conducted a closer analysis of the history and role of the municipality based on further literature study and interviews with officials.

Foster care provides a family‐like upbringing for children who cannot stay with their biological parents for various reasons. While the practice of paying foster parents is not questioned, the level of the fee and how it is spent (or not spent) are morally charged matters. Foster parents’ motives may be questioned by the media, neighbors, or social workers, who may suspect financial gain. Although
In an article in this journal, Katherine Drabiak argues that green lighting genome editing of human embryos is contrary to "fundamental human rights law." According to the author, genome editing of human embryos violates what we should recognize as a fundamental human right to inherit a genome without deliberate manipulation. In this reply article, we assess Drabiak's legal analysis and show metho

This article provides an overview of the findings from the Information Systems (IS) Well-Being Project that was started in the fall of 2020. There were two goals of this project: 1) to understand the physical, mental, social, and financial well-being of IS academics during the COVID-19 pandemic, and 2) to theorize the downstream effects of the pandemic on the health of the IS research ecosystem.
