The gallbladder (GB) is a susceptible organ, prone to various pathologies that can be identified using different imaging techniques. Transabdominal ultrasound (TUS) is typically the initial diagnostic method due to its numerous well-established advantages. However, in cases of uncertainty or when a definitive diagnosis cannot be established, computed tomography (CT) or magnetic resonance imaging may be employed to provide more detailed information.

There is an urgent need for alternative antimicrobial materials due to the growing challenge of bacteria becoming resistant to conventional antibiotics. This study demonstrates the creation of a biocompatible pH-switchable antimicrobial material by combining bacteria-derived rhamnolipids (RL) and food-grade glycerol monooleate (GMO). The integration of RL into dispersed GMO particles, with an inverse-type liquid crystalline cubic structure in the core, leads to colloidally stable supramolecular materials.

Background And Aims: Ulcerative colitis (UC) and Crohn's disease (CD) are the most common types of Inflammatory bowel disease (IBD), with variable responses to traditional therapies and unpredicted prognosis. In Egypt and most developing countries, the lack of recent epidemiological and prognostic data adversely affects management strategies. We collected and analyzed data of patients with IBD from multiple centers across Egypt to evaluate patients' clinical and epidemiological characteristics.

The maxillary permanent central incisor (MPCI) has been reported to be rotated in up to 96% of cleft patients. A severely rotated MPCI is highly visible when smiling, drawing attention to a repaired cleft lip, and is often the main presenting complaint of a patient with cleft lip and palate attending for orthodontic treatment. The benefit of interceptive orthodontic treatment to alleviate these concerns must be weighed up against the consequences of adding to the already substantial orthodontic burden likely to be faced by these patients.

Cytotoxic lymphocytes release proteins contained within the cytoplasmic cytolytic granules after recognition of infected or tumor target cells. These cytotoxic granular proteins (namely granzymes, granulysin, and perforin) are key immunological mediators within human cellular immunity. The availability of highly purified cytotoxic proteins has been fundamental for understanding their function in immunity and mechanistic involvement in sepsis and autoimmunity.

Dental transpositions are rare anomalies, which may present to the general dental practitioner or orthodontist. Transpositions occur less frequently in the mandible compared with the maxilla, with the most common mandibular transposition involving the mandibular lateral incisor and canine. The degree of displacement can vary from a relatively minor deviation to complete transposition of the mandibular lateral incisor with the adjacent canine tooth.

For all orthodontic patients, a detailed clinical examination is essential to obtain the correct diagnosis before the formulation of an orthodontic treatment plan. Additional information may be required from radiographs in order to supplement this clinical examination. While orthodontists principally prescribe dental panoramic tomographs for orthodontic patients to confirm the presence, position and morphology of unerupted teeth, the absence or presence of disease within the supporting structures may be overlooked.

The US Food and Drug Administration (FDA) approved the PD-L1 immunohistochemical assay, SP142, as a companion test to determine eligibility for atezolizumab therapy in patients with advanced triple negative breast cancer (TNBC) but data in lung cancer studies suggest the assay suffers from poor reproducibility. We sought to evaluate reproducibility and concordance in PD-L1 scoring across multiple pathologists. Full TNBC sections were stained with SP142 and SP263 assays and interpreted for percentage (%) immune cell (IC) staining by 19 pathologists from 14 academic institutions.

The introduction of Prostate Specific Antigen (PSA) screening has caused a stage shift in diagnosis of prostate cancer and an increasing number of patients receiving early diagnosis. This has led to early detection of limited foci of cancer on prostate biopsy, and clinically insignificant prostate cancer at radical prostatectomy. Therefore, current methods for sampling, diagnosing and managing prostate cancer have significantly evolved in recent years.

Background: Membrane-associated guanylate kinase, WW and PDZ domain-containing protein 2 (MAGI2) promotes the activity of phosphatase and tensin homolog (PTEN). Recent studies suggest that dysregulation of this signaling pathway has a role in prostate carcinogenesis. Our study aims to determine the prognostic significance of MAGI2 expression in prostate cancer.

Introduction: We recently showed that the psycho-stimulant norepinephrine-dopamine reuptake inhibitor methylphenidate (MP) prolonged cold pain threshold and tolerance in adults with attention-deficit hyperactivity disorder (ADHD).

Objectives: The objectives of the present study were to: (1) examine whether MP has antinociceptive properties in healthy men; (2) test MP's effects on responses to aversive auditory stimuli. The underlying aim was to determine whether MP exerts antinociceptive properties or more generalized, nonspecific attenuating effects on different aversive sensory modalities.

Objectives: Pathologic intraoperative consultation (IOC) is a common approach for segregating the subset of patients with endometrial cancer who likely require a lymphadenectomy.

Methods: We evaluate factors related to the performance and value of IOC, including the accuracy of frozen sections, "gross-only examinations," and obtaining random sections when a gross lesion is not apparent.

Results: IOC was performed by gross examination only in 17 (8%) of 250 cases, the specificity and negative predictive value of which in diagnosing cancer were 100% and 85%, respectively.

Many methods of analysis to predict survival of invasive mammary carcinoma in the post-neoadjuvant setting utilize tumor cellularity alone or in combination with other tumor features. The goal of this study was to evaluate the prognostic value of tumor cellularity in primary non-treated carcinoma. We used 366 cases of invasive breast carcinoma to determine invasive tumor cellularity (%) by reviewing a representative excisional tumor section and correlated this with breast cancer recurrence (BCR) and overall mortality (OM).
