Enhancing genetic discovery through narrow phenotyping in schizophrenia.

Background: Schizophrenia varies greatly from person to person, mainly because of its polygenic nature. Consequently, schizophrenia patients form distinct subphenotypes of schizophrenia, with specific symptom patterns and outcomes.

Methods: This study included 4257 adults, with long-term schizophrenia (control - 8955 individuals) who were assessed for schizophrenia with potentially severe outcomes based on following criteria: disability in functional and/or physical domains before the age of 40; severe negative symptoms (present in infancy or shortly after onset); a continuous course of the disease.

Multifunctional PAMAM Dendrimers Carrying SAHA, 5-FU, and a Therapeutic Gene for Targeted Co-Delivery Toward Colorectal Cancer Cells.

A promising approach to treat colorectal cancer (CRC) involves combining chemotherapy, epigenetics, and gene therapy to combat drug resistance. Multifunctional nanocarriers have emerged as a valuable tool for targeted CRC therapy. By delivering multiple treatments directly to cancer cells, these nanocarriers offer the potential for improved outcomes and reduced side effects.

Production cross sections of Rh and Ag in proton bombed Pb target with 400 MeV energy.

The accelerator-driven subcritical system (ADS) is a competitive option for next-generation nuclear energy systems. Production cross sections of long-lived residual radioactive nuclides in a proton-nuclide reaction are basic quantities for the calculation of accumulated radioactivity in the use of ADS systems. This work presents the production cross sections of Rh and Ag in a natural lead (Pb) target activated by 400 MeV protons.

The Role of BDNF in the Antidepressant Effects of Electroconvulsive Therapy.

Electroconvulsive therapy (ECT) is an effective treatment method for depression therapy. It produces a number of biological effects, including neurotrophic factors regulation. In the present paper, we investigated the ECT response in depressed rats subjected to the variable frequency ultrasound (20-45 kHz) and examined the contribution of brain-derived neurotrophic factor (BDNF) expression changes to the observed effects.

Chronic Ultrasound Prenatal Stress Altered the Brain's Neurochemical Systems in Newborn Rats.

Prenatal stress (PS) affects the development and functioning of the central nervous system, but the exact mechanisms underpinning this effect have not been pinpointed yet. A promising model of PS is one based on chronic exposure of pregnant rodents to variable-frequency ultrasound (US PS), as it mimics the PS with a psychic nature that most adequately captures the human stressors in modern society. The aim of this study was to investigate the effects of US PS on the brain neurotransmitter, neuropeptide, and neurotrophic systems of newborn Wistar rats.
