Article Synopsis
  • The ambient cistern (AC) and the ambient wing cistern (AWC) are complex anatomical structures in the brain, first defined by Dr. Bengt Liliequist in the 20th century, but have caused confusion in neuroanatomy over the years due to their intricate three-dimensional anatomy.
  • A thorough literature review identified 60 relevant research articles after filtering out unrelated studies, revealing that while multiple related cisterns are described, they are often not presented as singular entities in medical literature.
  • The study concludes that the AC and AWC are anatomically distinct yet interconnected structures, significant for diagnostic and surgical considerations related to brain masses near the tentorial hiatus, and can be approached via specific surgical methods.

Intermittent fasting (IF) is an intervention that involves not only dietary modifications but also behavioral changes with the main core being a period of fasting alternating with a period of controlled feeding. The duration of fasting differs from one regimen to another. Ramadan fasting (RF) is a religious fasting for Muslims, it lasts for only one month every one lunar year.

Background: More than a century has passed since it was discovered that many bacteria produce indole, but research into the actual biological roles of this molecule is just now beginning. The influence of indole on bacterial virulence was extensively investigated in indole-producing bacteria like Escherichia coli. To gain a deeper comprehension of its functional role, this study investigated how indole at concentrations of 0.

Background: Urinary Incontinence (UI) is a global health issue that mainly affects the female population worldwide. Different approaches have been sought for the management of UI including Pelvic floor muscle training (PFMT) using Virtual Reality (VR) gaming. We conducted this study to evaluate the effectiveness of VR gaming for rehabilitation of pelvic floor muscles (PFM) and improving urinary symptoms in patients with UI.

Article Synopsis
  • Antimicrobial resistance is a significant worldwide issue, particularly concerning the variability in antibiotic susceptibility within bacterial populations, exemplified by heteroresistance, where some bacteria are resistant while others are not.
  • This study investigates heteroresistance in various Gram-negative bacteria, analyzing 151 clinical isolates and identifying stable heteroresistant isolates (SHIs) using disc-diffusion techniques and genotypic analysis.
  • Findings revealed 51 heteroresistant subpopulations and 16 stable SHIs, highlighting that genetic mutations can lead to resistance even in predominantly sensitive populations, which poses risks for treatment effectiveness and should be further addressed for improved patient outcomes.

Introduction: The global healthcare burden of COVID-19 pandemic has been unprecedented with a high mortality. Metabolomics, a powerful technique, has been increasingly utilized to study the host response to infections and to understand the progression of multi-system disorders such as COVID-19. Analysis of the host metabolites in response to SARS-CoV-2 infection can provide a snapshot of the endogenous metabolic landscape of the host and its role in shaping the interaction with SARS-CoV-2.

The emergence of carbapenemase-producing poses a substantial risk to public health. It is essential to comprehend the influence of carbapenemase on the virulence characteristics of in order to devise successful strategies for combating these infections. In this study, we explored the distribution disparity of virulence determinants between carbapenemase-producing (CP-Kp, = 52) and carbapenemase-nonproducing (CN-Kp, = 43) isolates.

Background: Duplex or vermiform appendix refers to the presence of an appendix beside the naturally occurring one. Although, duplex appendix emerges from the caecum most of the time, yet it is encountered in other parts of the colon. Inflammation of duplex appendix may represent not only a clinical, but also a surgical dilemma, and this would be confusing further among patients who already had prior appendectomy.

Colonoscopy is an integral part of the lower bowel care and is generally considered a potentially safe diagnostic and therapeutic procedure performed as a daycare outpatient procedure. Colonoscopy is associated with different complications that are not limited to adverse events related to the bowel preparation solutions used, the sedatives used, but to the procedure related as well including bleeding and perforation. Injuries to the extra-luminal abdominal organs during colonoscopy are uncommon, however, serious complications related to the procedure have been reported infrequently in the literature.

Reprogramming human somatic cells into a pluripotent state, achieved through the activation of well-defined transcriptional factors known as OSKM factors, offers significant potential for regenerative medicine. While OSKM factors are a robust reprogramming method, efficiency remains a challenge, with only a fraction of cells undergoing successful reprogramming. To address this, we explored genes related to genomic integrity and cellular survival, focusing on iPSCs (A53T-PD1) that displayed enhanced colony stability.

Post-cholecystectomy iatrogenic bile duct injuries (IBDIs), are not uncommon and although the frequency of IBDIs vary across the literature, the rates following the procedure of laparoscopic cholecystectomy are much higher than open cholecystectomy. These injuries caries a great burden on the patients, physicians and the health care systems and sometime are life-threatening. IBDIs are associated with different manifestations that are not limited to abdominal pain, bile leaks from the surgical drains, peritonitis with fever and sometimes jaundice.

Background: Hydrocephalus or ventriculomegaly is a condition brought on by an overabundance of cerebrospinal fluid (CSF) in the ventricular system. The major contributor to posttraumatic hydrocephalus (PTH) is traumatic brain injuries (TBIs), especially in individuals with occupations set in industrial settings. A variety of criteria have been employed for the diagnosis of PTH, including the combination of neurological symptoms like nerve deficits and headache, as well as an initial improvement followed by a worsened relapse of altered consciousness and neurological deterioration, which is detected by computed tomography-brain imaging that reveals gradual ventriculomegaly.

Article Synopsis
  • - Autism spectrum disorder (ASD) is a neurodevelopmental condition with varying symptoms, primarily affecting social/communication skills and causing repetitive behaviors, with no approved diagnostic biomarker currently available.
  • - This study analyzed serum samples from 93 ASD cases and 28 healthy controls to identify autoantibodies associated with ASD using advanced protein-array technology, resulting in the discovery of 29 differential autoantibodies.
  • - The findings suggest that these autoantibodies are linked to essential brain functions, such as axonal guidance and metabolic pathways, and their expression varies with the age of individuals diagnosed with ASD.

In recent years, extensive research efforts have been directed toward pluripotent stem cells, primarily due to their remarkable capacity for pluripotency. This unique attribute empowers these cells to undergo self-renewal and differentiate into various cell types originating from the ectoderm, mesoderm, and endoderm germ layers. The delicate balance and precise regulation of self-renewal and differentiation are essential for the survival and functionality of these cells.

Aim Of The Study: Hepatocellular carcinoma (HCC) is a leading cause of mortality among patients with liver cirrhosis. According to the current practice guidelines, different ablations are used either as curative or palliative therapies. The current study aimed at determining bacterial infections as causes of fever and the predictive role of procalcitonin (PCT) among patients with HCC who had ablation therapy.

Foix-Chavany-Marie syndrome (FCMS) presents with anarthria and bilateral (B/L) central facio-linguo-velo-pharyngo-masticatory paralysis with "autonomic voluntary dissociation." The most common cause of FCMS is cerebrovascular disease, while rarer causes include central nervous system infection, developmental disorders, epilepsy, and neurodegenerative disorders. Even though this syndrome is also referred to as (B/L) anterior operculum syndrome, patients with lesion in sites other than (B/L) opercular regions also can develop the syndrome.
