population. Tryptophan is an essential amino acid catabolized initially to kynurenine (kyn), an immunomodulatory metabolite that we have previously shown to promote bone loss. Kyn levels increase with aging and have also been associated with neurodegenerative disorders. Picolinic acid (PA) is another tryptophan metabolite downstream of kyn. However, in contrast to kyn, PA is reported to be neuroprotective and further, to promote osteogenesis in vitro. Thus, we hypothesized that PA might be osteoprotective in vivo. In an IACUC-approved protocol, we fed PA to aged (23-month-old) C57BL/6 mice for eight weeks. In an effort to determine potential interactions of PA with dietary protein we also fed PA in a low-protein diet (8%). The mice were divided into four groups Control (18% dietary protein), +PA (700 ppm); Low-protein (8%), +PA (700 ppm). The PA feedings had no impact on mouse weight, body composition or bone density. At sacrifice bone and stem cells were collected for analysis, including μCT and RT-qPCR. Addition of PA to the diet had no impact on trabecular bone parameters. However, marrow adiposity was significantly increased in PA-fed mice, and in bone marrow stromal cells isolated from these mice increases in the expression of the lipid storage genes, Plin1 and Cidec, were observed. Thus, as a downstream metabolite of kyn, PA no longer showed kyn's detrimental effects on bone but instead appears to impact energy balance. Chronic pulmonary diseases such as chronic obstructive pulmonary disease, obstructive sleep apnea and obesity hypoventilation syndrome are common conditions which share decreased pulmonary ventilation and CO2 retention. CO2 is an end-product of metabolism of all body cells. When CO2 accumulates, it is recommended to consider measures to reduce its endogenous production. One such measure relates to the sources of energy ingested as nutrition. It is recommended to increase the intake of dietary lipids and reduce carbohydrates, as the former produces less endogenous CO2 when metabolized. Our hypothesis focuses on a different mechanism for reducing the availability of carbohydrates, especially glucose, as a fuel for body cells metabolism. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are a new class of oral anti-hyperglycemic agents. Physiologically, glucose filtered through kidney glomeruli is reabsorbed in the proximal convoluted tubule; SGLT2i inhibit this mechanism. learn more Therefore, glucose is secreted in the urine (glucosuria) and as a result glucose serum level is reduced. If glucose serum level is reduced, less glucose is available for metabolism, less CO2 is endogenously produced, and less CO2 must be expelled from the diseased lungs. It is hypothesized that these agents may be beneficial for patients with diabetes and concomitant pulmonary disease who retain CO2. By investigating the long-term observations at Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP), we find that the routinely used Beer-Bouguer-Lambert law and the models that empirically separate direct normal irradiance (DNI) from measurements of global horizontal irradiance (GHI) have dramatic and unexpected bias in computing cloudy-sky DNI. This bias has led to tremendous uncertainty in estimating the electricity generation by solar energy conversion systems. To effectively reduce the bias, this study proposes a physical solution of all-sky DNI that computes solar radiation in the infinite-narrow beam along the sun direction and the scattered radiation falls within the circumsolar region. link2 In sharp contrast with the other DNI models, this method uses a finite-surface integration algorithm that computes solar radiation in differential solid angles and efficiently infers its contribution to a surface perpendicular to the sun direction. The new model substantially reduces the uncertainty in DNI by a factor of 2-7. Targeting memory reconsolidation is an effective intervention for treating posttraumatic stress disorder (PTSD). Disrupting unconditioned stimulus (US)-retrieval-induced fear memory reconsolidation has become an effective therapeutic approach to attenuate fear memory, but the underlying molecular mechanisms remain unknown. Here, we report that US-retrieval-dependent increase in phosphatidylinositol 4-kinase IIα (Pi4KIIα) promotes early endosomal trafficking of AMPA receptors, leading to the enhancement of synaptic efficacy in basolateral amygdala (BLA) neurons. The inhibition of Pi4KIIα by an inhibitor or short hairpin RNA impaired contextual fear memory reconsolidation. This disruptive effect persisted for at least 2 weeks, which was restored by Pi4KIIα overexpression with TAT-Pi4KIIα. Furthermore, the blockade of early endosomal trafficking following US retrieval reduced synaptosomal membrane GluA1 levels and decreased subsequent fear expression. These data demonstrate that Pi4KIIα in the BLA is crucial for US-retrieval-induced fear memory reconsolidation, the inhibition of which might be an effective therapeutic strategy for treating PTSD. Core components of plastid protein import and the principle of using N-terminal targeting sequences are conserved across the Archaeplastida, but lineage-specific differences exist. Here we compare, in light of plastid protein import, the response to high-light stress from representatives of the three archaeplastidal groups. Similar to land plants, Chlamydomonas reinhardtii displays a broad response to high-light stress, not observed to the same degree in the glaucophyte Cyanophora paradoxa or the rhodophyte Porphyridium purpureum. We find that only the Chloroplastida encode both Toc75 and Oep80 in parallel and suggest that elaborate high-light stress response is supported by changes in plastid protein import. We propose the origin of a phenylalanine-independent import pathway via Toc75 allowed higher import rates to rapidly service high-light stress, but with the cost of reduced specificity. Changes in plastid protein import define the origin of the green lineage, whose greatest evolutionary success was arguably the colonization of land. The characterization of mutational processes in terms of their signatures of activity relies mostly on the assumption that mutations in a given cancer genome are independent of one another. Recently, it was discovered that certain segments of mutations, termed processive groups, occur on the same DNA strand and are generated by a single process or signature. Here we provide a first probabilistic model of mutational signatures that accounts for their observed stickiness and strand coordination. The model conditions on the observed strand for each mutation and allows the same signature to generate a run of mutations. It can both use known signatures or learn new ones. We show that this model provides a more accurate description of the properties of mutagenic processes than independent-mutation achieving substantially higher likelihood on held-out data. We apply this model to characterize the processivity of mutagenic processes across multiple types of cancer. Cold shock proteins (Csps) are small and highly conserved proteins that have target RNA- and DNA-binding activities. Csps play roles in different cellular processes and show functional redundancy. Ralstonia solanacearum, the agent of bacterial wilt, has 4 or 5 Csps based on genome analysis. However, the functions of all Csps in R. solanacearum remain unclear. According to phylogenetic analysis, the Csps from R. solanacearum are clustered into a group with CspD from E. coli. Here, we studied the role of CspD3, which was closer to CspD of E. coli in the phylogenetic tree. A cspD3 deletion strain was constructed to assess its effect on the phenotype of R. solanacearum, including growth, biofilm formation, motility, and virulence. The results showed that cspD3 of R. solanacearum was not necessary for normal growth, cold-shock adaptation, or biofilm formation. However, deletion of cspD3 in R. solanacearum CQPS-1 led to increased swimming motility, and the mean diameters of swimming haloes produced by the ΔcspD3 mutant were 1.3-fold larger than those produced by wild-type strain and 1.2-fold larger than those produced by the complemented strain. More importantly, the virulence of the cspD3 deletion mutant on susceptible tobacco plants was significantly attenuated compared to the wild-type strain. At 20 days after inoculation, the disease index of the ΔcspD3 mutant was 2.27, which was reduced by 1.6-fold relative to the wild-type strain. To assess the molecular response influenced by cspD3, the expressions of the main motility-associated genes and virulence-associated genes including flgM, fliA, pehS, pehR, hrpG, xpsR, and prhI in R. solanacearum were measured. The results showed that the expressions of hrpG, xpsR, and prhI were significantly decreased in cspD3 deletion mutant. Collectively, our findings showed that Csps are involved in the regulation of motility and virulence in R. solanacearum. The study explored whether target detection in a five-character string depends on whether a letter or a non-letter was presented, as a predesignated target. Skilled readers had to identify a single letter or non-letter in a five-character string, randomly composed of letters and non-letters. link3 It was found that an analytic processing strategy is automatically elicited if participants were instructed to detect a letter target. In this instance, a linear model best explained the RT variance for letters with increasing RTs from left to right, suggesting a serial item-by-item reading-specific strategy comparable to alphabetic reading. For non-letters, in contrast, a symmetrical U-shaped function best explained the RT variance, suggesting a symmetrical scanning-out from the central to the terminal positions of the string. Since the design precludes orthographic and semantic influences, it can be concluded that a reading-specific strategy for alphabetic processing is automatically activated if the string is scanned for a letter-target. Thus, the pre-designated target triggers the strategy for processing the string and determines related position effects. The results suggest that effects from earlier studies, which showed an analytic processing preference for isolated letters (APPLE) in recognition tasks, as a consequence of literacy acquisition, generalize to the processing of letters in strings. Microorganism-derived dissolved organic nitrogen (mDON) represents a significant and inevitable portion of dissolved organic nitrogen (DON) in the wastewater biotreatment processes. In the existing method, mDON concentrations are indirectly measured by the values of DON concentrations from the reactors with DON-free influent. However, this becomes problematic when influent contains DON. Especially when the real wastewater is involved, the paucity of the direct methods to quantitatively measure mDON is a major barrier to further research. This limitation is due to the difficulty of segregating mDON from the other nitrogenous organics, e.g., influent DON. In this study, we propose the ASM-mDON model based on ASM #1, which incorporates the production and consumption of mDON in the activated sludge processes to predict the mDON concentrations. In four independent lab-scale tests, our model was established and calibrated to obtain the accurate values of mDON (R2 = 0.929, p less then 0.05), and the validity and applicability of the model were successfully examined by comparing the simulated and measured data.
