Auditory/visual hallucinations and perceptual anomalies are one of the core symptoms experienced by patients with schizophrenia. Studies have implicated lateral occipital cortex (LOC) as one of the areas to be aberrantly functioning in schizophrenia, possibly associated with the auditory/visual symptoms of schizophrenia. Here we report of a case of a 29-year-old female diagnosed with treatment resistant schizophrenia on clozapine with persistent auditory verbal hallucinations (AVH) and visual anomalies.

Article Synopsis
  • Osteon orientation influences the elasticity and fracture behavior of cortical bone, similar to how fiber orientation affects composite materials.
  • The study aimed to predict the effects of osteon orientation, load, and crack length on the fracture characteristics of cortical bone using advanced modeling techniques like XFEM and LEFM.
  • Results indicated that both the loading conditions and osteon orientations significantly affected stress intensity factor (SIF) values, with mode-II loading producing higher SIFs than mode-I, and both modes affecting crack behavior differently.

Article Synopsis
  • The paper reviews the real-time equation-of-motion coupled-cluster (RT-EOM-CC) cumulant Green's function approach, highlighting its potential uses and limitations compared to the original time-dependent coupled cluster (TDCC) method.
  • An enhanced double TDCC ansatz is proposed to improve accuracy in expansion limits, while a new cluster-analysis method is introduced to better identify peaks in the spectral function, especially useful for understanding complex many-body effects.
  • Initial tests apply this RT-EOM-CC approach to single impurity Anderson models, allowing for comparisons with other Green's function methods to evaluate effectiveness and accuracy in producing impurity Green's functions.

Article Synopsis
  • Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation method that shows promise in helping individuals with schizophrenia manage auditory verbal hallucinations (AVH).
  • Traditional in-clinic tDCS requires frequent visits due to its short-lived effects, but home-based tDCS could provide a more accessible solution if safety and standardization measures are implemented.
  • A case study demonstrated successful administration of tDCS at home with proper caregiver training and a standard operating procedure (SOP), leading to sustained improvements in AVH over ten days without adverse effects.

Article Synopsis
  • Dysregulated prediction error-signalling may lead to auditory hallucinations in schizophrenia, with metrics like rMMN, RP, DN, and MMN helping to assess this relationship.* -
  • In a study involving 23 schizophrenia patients with auditory hallucinations and 23 healthy controls, significant differences were found in deviance detection and prediction error signaling, particularly with DN and MMN amplitudes being lower in the patients.* -
  • The results suggest that auditory hallucinations interfere with sensory adaptation and detection abilities, indicating that schizophrenia patients may not process auditory information effectively despite unimpaired short-term memory responses.*

Here, we investigate the hypothesis that despite the existence of at least two high-density amorphous ices, only one high-density liquid state exists in water. We prepared a very-high-density amorphous ice (VHDA) sample and rapidly increased its temperature to around 205 ± 10 K using laser-induced isochoric heating. This temperature falls within the so-called "no-man's land" well above the glass-liquid transition, wherein the IR laser pulse creates a metastable liquid state.

Even though researches have shown that biochar can improve soil-health and plant-growth even in harsh environments and get rid of harmful heavy metals and new contaminants, it is still not sustainable, affordable, or effective enough. Therefore, scientists are required to develop nanomaterials in order to preserve numerous aquatic and terrestrial species. The carbonaceous chemical known as nano-biochar (N-BC) can be used to get rid of metal contamination and emerging contaminants.

The emergence of new SARS-CoV-2 variants continues to cause challenging problems for the effective control of COVID-19. In this study, we tested the hypothesis of whether a strategy of multivalent and sequential heterologous spike protein vaccinations would induce a broader range and higher levels of neutralizing antibodies against SARS-CoV-2 variants and more effective protection than homologous spike protein vaccination in a mouse model. We determined spike-specific IgG, receptor-binding inhibition titers, and protective efficacy in the groups of mice that were vaccinated with multivalent recombinant spike proteins (Wuhan, Delta, Omicron), sequentially with heterologous spike protein variants, or with homologous spike proteins.

Background: Brain-derived neurotrophic factor (BDNF) is essential for antidepressant treatment of major depressive disorder (MDD). Our repeated studies suggest that DNA methylation of a specific CpG site in the promoter region of exon IV of the BDNF gene (CpG -87) might be predictive of the efficacy of monoaminergic antidepressants such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and others. This trial aims to evaluate whether knowing the biomarker is non-inferior to treatment-as-usual (TAU) regarding remission rates while exhibiting significantly fewer adverse events (AE).
