Article Synopsis
  • * Advances in diagnosis and treatment, particularly through analyzing molecular markers, have led to new targeted therapies that improve the outlook for some patients, although many are diagnosed late and have limited life expectancy.
  • * The article aims to summarize NSCLC's key features and the progress in targeted therapies, while also discussing the challenges faced in managing this form of cancer.

Lung cancer represents one of the most common neoplasms and the main cause of cancer‑associated death worldwide. Its relationship with different risk factors such as tobacco, which is its main etiological factor, has been clearly established and despite the numerous advances achieved in the diagnosis, treatment and follow‑up of these patients, the life expectancy of these patients is notably limited. Furthermore, its treatment is not exempt from comorbidities and frequently it neither provides optimal control of the disease nor improve the quality of life of these patients.

Background: Coats plus syndrome or cerebroretinal microangiopathy with calcifications and cysts (CMCC) is an exceedingly rare autosomal recessive disorder that predominantly affects the microvasculature in the retina, brain, bones, and gastrointestinal system. Unlike Coats disease, CMCC is bilateral and affects multiple organ systems.

Materials And Methods: Case report.

Background And Objective: Research has documented the stigma that individuals with degenerative neurological diseases experience, but caregivers also experience stigma by association (i.e., affiliate stigma).

Cancer is a complex disease affecting millions of people worldwide, with over a hundred clinically approved drugs available. In order to improve therapy, treatment, and response, it is essential to draw better maps of the targets of cancer drugs and possible side interactors. This study presents a large-scale screening method to find associations of cancer drugs with human genes.

Background/objective: Given the growing population of individuals with Parkinson's disease (PD) worldwide and the growing need for family members to take on a caregiving role, it is critical that cross-cultural differences be examined in order to better meet the needs of PD caregivers. The purpose of this study was to examine the connections between the unmet needs and mental health of PD caregivers differentially in Mexico and the United States.

Methods: In Parkinson's clinics at public, academic medical centers, PD caregivers from Mexico (n = 148) and the United States (n = 105) completed measures of unmet family needs and mental health.

Unlabelled: Fetal Magnetic Resonance Imaging (MRI) is increasingly used in prenatal evaluations.

Objective: Identify common brain malformations on fetal MRI and evaluate perinatal course.

Methods: Fetal consultations from 10/2016 to 12/2017 reviewed.

Background And Purpose: To examine prenatal MRI and postnatal imaging in fetuses with congenital aqueductal stenosis (CAS) to determine the frequency of association of rhombencephalosynapsis (RES) and how it may affect neonatal intensive care unit (NICU) course.

Materials And Methods: A single center IRB-approved retrospective study of children with CAS was performed. Prenatal MRI, postnatal images, and clinical data were reviewed.

Purpose: To evaluate the effects of progressive hydrocephalus on the developing brain in a cohort of fetuses diagnosed with congenital aqueduct stenosis by comparing prenatal magnetic resonance imaging and postnatal imaging.

Methods: This IRB approved single center retrospective review of prenatally diagnosed children with congenital aqueduct stenosis interrogated changes in the brain between prenatal and postnatal imaging and analyzed statistics using SAS software package version 9.3.

Unraveling the protein interaction wiring that occurs in human cells as a scaffold of biological processes requires the identification of all elements that constitute such molecular interaction networks. Proteome-wide experimental studies and bioinformatic comprehensive efforts have provided reliable and updated compendiums of the human protein interactome. In this work, we present a current view of available databases of human protein-protein interactions (PPIs) that allow building protein interaction networks.

Article Synopsis
  • - Subependymal giant cell astrocytomas (SEGA) are slow-growing tumors often found in patients with tuberous sclerosis complex (TSC) and can lead to serious complications like obstructive hydrocephalus, requiring regular MRI monitoring.
  • - Current guidelines suggest treating asymptomatic SEGAs with mTOR inhibitors, which have proven effective in trials, while symptomatic cases usually require surgical removal, though surgery can come with significant risks.
  • - A case study of a seven-year-old boy revealed that the mTOR inhibitor everolimus led to a quick reduction in tumor size and improved symptoms, suggesting it can be an effective alternative to surgery for managing symptomatic SEGAs.

Objective: Given reports of high pain thresholds and reduced auditory response in individuals with agenesis of the corpus callosum (AgCC), this study investigated whether affected participants report atypical experiences and behaviors on a well-established sensory processing measure.

Methods: Fourteen participants with AgCC (ages 11-59) completed the Adolescent/Adult Sensory Profile (Brown & Dunn, 2001). Sensory profile scales were classified as "Atypical" if they were more than 1 standard deviation from the mean.

The neural underpinnings of sensory processing differences in autism remain poorly understood. This prospective magnetoencephalography (MEG) study investigates whether children with autism show atypical cortical activity in the primary somatosensory cortex (S1) in comparison with matched controls. Tactile stimuli were clearly detectable, and painless taps were applied to the distal phalanx of the second (D2) and third (D3) fingers of the right and left hands.

Anginex, a designed peptide 33mer, is known to function both as an antiangiogenic and bactericidal agent. Solving the NMR solution structure of the peptide is key to understand better its structure-activity relationships and to design more bioactive peptides and peptide mimetics. However, structure elucidation of anginex has been elusive due to subunit exchange-induced resonance broadening.

Anginex is a designed peptide 33mer that functions as a cytokine-like agent to inhibit angiogenesis. Although this short linear peptide has been shown by NMR and CD to form a nascent beta-sheet conformation in solution, the actual bioactive structure formed upon binding to its receptor on the surface of endothelial cells could be quite different. By using a series of double-cysteine disulphide-bridged analogues, we provide evidence in the present study that the beta-sheet is in fact the bioactive conformation of anginex.
