Objective: This study evaluated the association between attention-deficit/hyperactivity disorder (ADHD) and psychometrically defined cognitive variables across the adult life span, using data from a large controlled study of adults with and without ADHD.
Method: Comparisons were made between 2 groups of adults: participants with DSM-IV-diagnosed ADHD who had never received pharmacotherapy for their ADHD (n = 116) and 146 control participants. Subjects received a battery assessing IQ, neuropsychological measures, and academic testing. We modeled cognitive measures as a function of age and group status using linear regression. The study was conducted at Massachusetts General Hospital, Boston, between 1998 and 2003.
Results: ADHD and control subjects maintained similar, statistically significant differences in all psychometrically assessed measures of cognition within each decade that was represented (all P values < .01).
Conclusion: The negative impact of ADHD on multiple, nonoverlapping, psychometrically assessed measures of cognition remained constant across the life cycle, suggesting that the association between ADHD and cognition neither improves nor deteriorates across the life cycle.

This study aimed to determine the effects of novel N-{3-[(pyridin-4-yl)carbamoyl] phenyl} thiophene-2-carboxamide or PCPTC chemical moiety loaded Poly(lactic-co-glycolic acid)-Poly (Ethylene glycol) or (PLGA-PEGylated) NP as an anti-metastatic Ran GTPase therapeutic agent on MDA-MB231 triple-negative human breast cancer cells. Molecular docking and MD simulation was done to determine the binding potential of novel carboxamide PCPTC with Ran GTPase. PLGA and PLGA-PEG based NP encapsulating PCPTC were fabricated using the Modified Double Emulsion Solvent Evaporation Technique and characterized for size, zeta potential, polydispersity and morphology.

Background: Acute myeloid leukemia (AML) is a heterogeneous hematological malignancy caused by disorders in stem cell differentiation and excessive proliferation resulting in clonal expansion of dysfunctional cells called myeloid blasts. The combination of chemotherapeutic agents with natural product-based molecules is promising in the treatment of AML. In this study, we aim to investigate the anti-cancer effect of Rapamycin and Niacin combination on THP-1 and NB4 AML cell lines.

Zn-Mn aqueous batteries (ZMABs) are widely recognized as a promising candidate for large-scale energy storage due to their cost-effectiveness, high safety and environmental friendliness. However, the practical application of ZMABs is hindered by inherent electrical contact loss, hydrogen evolution and dendrite growth on traditional anodes. Here, a three-tiered golf anode with high conductivity is developed to simultaneously enhance the reversibility of Zn and Mn metals.

Sulfurized polyacrylonitrile (SPAN) presents an opportunity to replace elemental sulfur as a "shuttle-free" cathode for secondary Li-S batteries, which can be an ideal choice for stationary energy storage due to its abundance, low cost, and sustainability. The electrolyte options for the state-of-the-art SPAN batteries have been limited to the flammable carbonate and ether ones, which raises safety concerns. Here, we explored the use of a non-flammable acetonitrile (AN) electrolyte for SPAN battery for the first time and identified the irreversible cleavage of C-S bonds of SPAN as the main reason for the failure of SPAN in AN electrolyte.

Unlabelled: The composition of bacterial transcriptomes is determined by the transcriptional regulatory network (TRN). The TRN regulates the transition from one physiological state to another. Here, we use independent component analysis to monitor the composition of the transcriptome during the transition from the exponential growth phase to the stationary phase.
