Most of the rapid inhibitory neurotransmission in the brain is mediated through activation of the γ-aminobutyric acid (GABA) type A (GABA) receptor, which is a ligand-gated ion channel. GABA receptor activation via GABA binding allows for an intracellular influx of Cl ions, thus inducing cellular hyperpolarization. Each GABA receptor consists of a combination of five subunits, and several subunits have been proposed as biomarkers and therapeutic targets in cancer.

Previous work suggests that similar cognitive processes contribute to memory and comprehension. This is unsurprising as both begin with a common process: encoding. Despite this, the investigation of techniques that benefit memory and comprehension has proceeded separately.

We compared the benefit of production and drawing on recall of concrete and abstract words, using mixed- and pure-list designs. We varied stimulus and list types to examine whether the memory benefit from these strategies was sustained across these manipulations. For all experiments, the memory retrieval task was free recall.

A series of four experiments tested the assumptions of the most prominent and longstanding account of item-method directed forgetting: the selective rehearsal account. In the item-method directed forgetting paradigm, each presented item is followed by its own instructional cue during the study phase - either to-be-forgotten (F) or to-be-remembered (R). On a subsequent test, memory is poorer for F items than for R items.

Background: Global pediatric healthcare reveals significant morbidity and mortality rates linked to respiratory, cardiac, and gastrointestinal disorders in children and newborns, mostly due to the complexity of therapeutic management in pediatrics and neonatology, owing to the lack of suitable dosage forms for these patients, often rendering them "therapeutic orphans". The development and application of pediatric drug formulations encounter numerous challenges, including physiological heterogeneity within age groups, limited profitability for the pharmaceutical industry, and ethical and clinical constraints. Many drugs are used unlicensed or off-label, posing a high risk of toxicity and reduced efficacy.

Background And Objectives: Newborns, particularly premature ones, are vulnerable to bacterial infections and often receive antibiotics, disrupting their normal intestinal microbiota. Probiotics have multiple health benefits and are recommended for restoring balance, but caution is needed due to potential consequences, such as promoting antibiotic resistance. Therefore, this study aimed to conduct a systematic review to assess current knowledge regarding the impact of probiotics on antibiotic resistance in newborns.

Objective: Memory and affective processing were compared in young adults with a remote mild traumatic brain injury (mTBI), to healthy younger and older adults. We evaluated memory performance when encoding was done under multi-tasking (divided attention) conditions, likely to exacerbate cognitive and psychological symptoms in mTBI.

Methods: Participants studied pairs of unrelated words under either full or divided attention conditions.

Purpose: In this study, we present DeepVirusClassifier, a tool capable of accurately classifying Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) viral sequences among other subtypes of the coronaviridae family. This classification is achieved through a deep neural network model that relies on convolutional neural networks (CNNs). Since viruses within the same family share similar genetic and structural characteristics, the classification process becomes more challenging, necessitating more robust models.

This work proposes an implementation of the SHA-256, the most common blockchain hash algorithm, on a field-programmable gate array (FPGA) to improve processing capacity and power saving in Internet of Things (IoT) devices to solve security and privacy issues. This implementation presents a different approach than other papers in the literature, using clustered cores executing the SHA-256 algorithm in parallel. Details about the proposed architecture and an analysis of the resources used by the FPGA are presented.

Memory for words that are drawn or sketched by the participant, rather than written, during encoding is typically superior. While this drawing benefit has been reliably demonstrated in recent years, there has yet to be an investigation of its neural basis. Here, we asked participants to either create drawings, repeatedly write, or list physical characteristics depicting each target word during encoding.

Spontaneous thought is common in daily life, and includes recurrent involuntary autobiographical memories (IAMs; memories retrieved unintentionally and repetitively) and mind wandering (MW). Both recurrent IAMs and MW are often unintentional or unconstrained, and both predict symptoms of mental health disorders. However, not all MW is unintentional, and not all IAMs are unconstrained.

Researchers debate whether recurrent involuntary autobiographical memories (IAMs; memories of one's personal past retrieved unintentionally and repetitively) are pathological or ordinary. While some argue that these memories contribute to clinical disorders, recurrent IAMs are also common in everyday life. Here, we examined how the content of recurrent IAMs might distinguish between those that are maladaptive (related to worse mental health) versus benign (unrelated to mental health).

  • Gliomas are the most common type of central nervous system tumors, significantly impacting both adults and children, with glioblastoma (GBM) being the most critical and aggressive form in adults with a poor survival outlook.
  • The protein CD114 acts as a receptor related to granulocyte colony stimulating factor (GCSF) and is known as a cancer stem cell marker, showing higher expression in various cancers, including certain gliomas.
  • Our research indicates that higher levels of CD114 mRNA in gliomas, particularly astrocytomas and GBM, correlate with worse overall survival (OS) for patients, suggesting that CD114 could serve as a potential prognostic marker for GBM.
