Few relevant research attempts have been made to determine heavy metal resistance mechanisms of rhizomatous perennial plants. Thus, it is pertinent to investigate the physiological and biochemical changes in Phragmites australis under metal-stressed conditions to facilitate the development of strategies to enhance copper (Cu) tolerance. We measured parameters related to plant growth and development, metal translocation and physiological responses of P. australis subjected to Cu stress. In addition, the differentially expressed proteins (DEP) were evaluated using the isobaric tag for relative and absolute quantification (iTRAQ) system. A large amount of copper accumulates in the roots of P.australis, but the growth parameters were not sensitive to Cu. However, the high concentration of Cu reduced the content of chlorophyll a and chlorophyll b, and the expression of important photosynthesis proteins PsbD, PsbO and PsaA were all down-regulated, so photosynthesis was inhibited. In contrast, the content of ascorbic acid and proline both increased with the increase of copper stress. P.australis fixed a large amount of Cu in its roots, limiting the migration of Cu to other parts of the plant. Moreover, Cu stress can affect photosynthesis by inhibiting the activity of PSI, PSII and LHCII. In addition, P.australis synthesizes ascorbic acid through the D-mannose/L-galactose pathway, and synthesizes proline through the ornithine pathway. Ascorbic acid and proline can increase Cu tolerance and protect photosynthesis. These results provide a theoretical basis for understanding the tolerance and repair mechanisms of plants in response to heavy metal pollution.Organisms must frequently evaluate the amount of effort to invest in pursuing future rewards. Despite explicit awareness of the potential benefits of cognitive work, individuals vary in their willingness to attempt cognitively demanding tasks, regardless of intellectual ability. Such differences may suggest that the degree to which cognitive effort degrades perceived outcome value is a subjective, rather than objective, process, similar to risk and delay discounting. Although numerous studies suggest the orbitofrontal cortex (OFC) is important for allowing subjective value estimates to be updated and/or used in cost/benefit decision-making, the causal role of the OFC in valuations of mental effort has received scant investigation. We therefore trained 24 female Long-Evans rats on the rodent cognitive effort task (rCET) and assessed performance following temporary bilateral inactivation of the ventrolateral OFC (vlOFC). In the rCET, rats decide at trial outset whether to perform an easy or hard attentional challenge, namely to localize a brief visual stimulus to one of five possible locations. The difficulty of the challenge is determined by the stimulus duration (1.0 vs. 0.2s for easy vs. hard trials respectively), and success on hard trials results in double the sugar pellet rewards. Somewhat surprisingly, inactivations of the vlOFC did not affect rats' willingness or ability to exert cognitive effort for larger rewards, despite increasing omissions and motor impulsivity on-task. When considered with previous work, it appears the vlOFC plays a minimal role in cognitive effort allocation specifically, and in valuations of effort more generally.
Acquired hepatocerebral degeneration (AHD) and hepatic encephalopathy (HE) are neurological complications of chronic liver disease (CLD) with portosystemic shunt. While HE is common, AHD is a rare entity, and the clinical imaging relationships observed in small series lack validation in large patient cohorts. The aim of this study was to characterize a cohort of AHD patients and to explore possible associations with HE coexistence.

We performed a retrospective analysis of patients with a working AHD diagnosis, between 2008 and 2019. Clinical, laboratory, imaging and neuropsychological results at first neurological observation were reviewed and compared between the 'AHD' group and the 'AHD with HE' group.

A total of 76 patients were recruited. The most frequent neurological manifestations were neuropsychiatric (93.4%) and extrapyramidal (84.2%). Only 38% of patients had hypermanganesemia. Compared with the AHD group, the AHD with HE group had more hyperkinetic movement disorders (71.4% vs. 38.5%; P=0.05)restoration through liver transplantation improved survival. Our report provides a detailed description of the phenotype and long-term outcome of AHD, with relevance for diagnosis and treatment.
There is a lack of comparative safety data on the risk of pseudotumor cerebri syndrome (PTCS) associated with different hormonal contraceptives. We sought to quantify the risk of PTCS associated with eight different types of hormonal contraceptives compared with oral levonorgestrel.

We conducted a retrospective cohort study, with a case-control analysis of 4871504 women aged 15-45 years in the period 2008-2015, using IQVIA Ambulatory Electronic Medical Records data in the USA. Patients who used nine different contraceptive agents including intrauterine levonorgestrel, medroxyprogesterone injection, etonogestrel/ethinyl estradiol vaginal ring and combination oral contraceptives (COCs) that contained ethinyl estradiol and the progestins levonorgestrel, norgestimate, desogestrel, norethindrone and drospirenone, were included. Diagnosis of PTCS was defined using the first International Classification of Diseases, 9th or 10th revision, code for intracranial hypertension in patients who had also received an imaging code in the 30days prior to the index date.

A total of 3323 PTCS cases and 13292 matched controls were identified. No increase in risk was found when analysing intrauterine levonorgestrel or COCs containing desogestrel, norethindrone, drospirenone, norgestimate or norgestrel versus COC levonorgestrel. Procyanidin C1 chemical structure The adjusted incidence rate ratio for etonogestrel/etonogestrel/ethinyl estradiol vaginal ring and medroxyprogesterone suspension compared with levonorgestrel COC was 4.45 [95% confidence interval (CI) 1.98-9.96] and 2.20 (95% CI 1.33-3.64), respectively.

This study found an elevated risk for PTCS among users of etonogestrel vaginal ring and medroxyprogesterone suspension when compared with oral levonorgestrel. Future studies are needed to confirm these findings.
