Measuring recognition memory in zebrafish larvae: issues and limitations
Recognition memory is the capacity to recognize previously encountered objects, events or places. This ability is crucial for many fitness-related activities, and it appears very early in the development of several species. In the laboratory, recognition memory is most often investigated using the novel object recognition test (NORt), which exploits the tendency of most vertebrates to explore novel objects over familiar ones. Despite that the use of larval zebrafish is rapidly increasing in research...

Activating genomic alterations in the Gs alpha gene (GNAS) in 274 694 tumors
ABSTRACT Activating point mutations in two codons (R201 and Q227) in the alpha subunit of the stimulatory GTP binding protein (GNAS) gene ‐ coined gsp mutations ‐ were originally reported in growth hormone (GH) secreting pituitary adenomas. In these tumor types, gsp activating mutations were associated with uncontrolled intracellular cAMP accumulation leading to cellular proliferation and tumor formation. Since the original description of gsp mutations in pituitary and later thyroid neoplasia,...

Uricase-deficient rat is generated with CRISPR/Cas9 technique
Urate oxidase (uricase, Uox) is a big obstacle for scientists to establish stable animal models for studying hyperuricemia and associated disorders. Due to the low survival rate of uricase-deficient mice, we generated a Uox-knockout model animal from Sprague Dawley (SD) rats using the CRISPR/Cas9 technique by deleting exons 2 to 4 of the Uox gene. The uricase-deficient rats were named “Kunming-DY rats”, and were apparently healthy with more than a 95% survival up to one year. The male rats’ serum...

We showed recently that a mycobacterium‐specific loop of the enzyme’s rotary γ subunit plays a role in coupling of ATP synthesis within the enzyme complex. Here, we report the discovery of a novel antimycobacterial, termed GaMF1, targeting this γ subunit loop. Biochemical and Nuclear Magnetic Resonance studies show that GaMF1 inhibits ATP synthase activity...

Nonadiabatic (NA) molecular dynamics combined with time‐domain density functional theory calculations demonstrate that the formation energy of a lead vacancy decreases from 0.29 eV in pristine MAPbI 3 (MA= CH 3 NH 3 + ) to over ‐2 eV in the perovskite in the presence water regardless of its oxidation...

Predictable selectivity in remote C‐H Oxidation of steroids via analysis of substrate binding mode
Predictability is a key requirement to encompass late‐stage C‐H functionalization in synthetic routes. However, prediction (and control) of reaction selectivity is usually challenging, especially for complex substrate structures and elusive transformations such as remote C( sp 3 )‐H oxidation, as it requires to distinguish a specific C‐H bond from many others with similar reactivity. Herein, we develop a strategy for predictable, remote C‐H oxidation that entails substrate binding to a supramolecular...

Electrochemical Reduction of CO2 to Ethane through Stabilization of an Ethoxy Intermediate
Electrochemical conversion of CO2 to ethane is seldom observed because of the generally higher selectivity towards methane, ethylene, and ethanol. Consequently, little experimental evidence for its reaction mechanism exists and thus remains largely unknown. Here, by combining electrochemistry with in‐situ X‐ray absorption fine structure and in‐situ Raman techniques, we study iodide‐derived copper (ID‐Cu) and oxide‐derived copper (OD‐Cu) systems to obtain a deeper understanding of the CO2 to ethane...

Vitamin D Supplementation in Pregnancy Does Not Prevent School‐Age Asthma
Abstract It is hypothesized that prenatal vitamin D deficiency may contribute to the development of childhood wheezing and asthma. Beyond its known functions in bone development and health, vitamin D is emerging as a pleiotropic hormone exerting several extraskeletal effects, some of which could reduce the risk of asthma. Experimental evidence shows that vitamin D is an important regulator of foetal and neonatal lung growth. It can also modulate innate and adaptive immune responses, enhancing antiviral...

Glutamatergic Inputs to GABAergic Interneurons in the Motor Thalamus of Control and Parkinsonian Monkeys
Abstract The primate ventral motor thalamus contains a large number of GABAergic interneurons of poorly understood function and anatomical connectivity. Glutamatergic inputs to these cells arise predominantly from corticothalamic (in both basal ganglia‐ and cerebellar‐receiving ventral motor thalamic territories; BGMT and CBMT, respectively) and cerebellothalamic terminals (in CBMT). In Parkinson’s Disease patients and animal models, neuronal activity is abnormal within both BGMT and CBMT. Historically,...

Condition dependent mortality exacerbates male (but not female) reproductive senescence and the potential for sexual conflict
Abstract Disentangling the relationship between age and reproduction is central to understand life‐history evolution, and recent evidence shows that considering condition‐dependent mortality is a crucial piece of this puzzle. For example, non‐random mortality of “low‐condition” individuals can lead to an increase in average lifespan. However, selective disappearance of such low‐condition individuals may also affect reproductive senescence at the population level due to trade‐offs between physiological...
