The Given M2A(R) ingestible, disposable imaging capsule contains a miniature video camera, which, when it is swallowed, can transmit images to a computer. It is used to detect abnormalities in the inner lining of the small intestine. In studies of small numbers of patients, the capsule demonstrates superior diagnostic rates for disorders of the small intestine among adults and children. All studies report fewer complications or less patient discomfort with the use of the capsule. Limiting factors are the time taken by physicians to evaluate the images, the lack of comparative evaluations of the capsule's sensitivity and specificity compared to conventional procedures and the impact of its cost.

Dual-Mechanism Gastroretentive Tablets with Encapsulated Gentian Root Extract.
Pharmaceutics
January 2025
Faculty of Pharmacy, University of Belgrade, 11221 Belgrade, Serbia.
This study aimed to develop gastroretentive tablets based on mucoadhesive-floating systems with encapsulated gentian (, Gentianaceae) root extract to overcome the low bioavailability and short elimination half-life of gentiopicroside, a dominant bioactive compound with systemic effect. The formulation also aimed to promote the local action of the extract in the stomach. Tablets were obtained by direct compression of sodium bicarbonate (7.

The development of targeted drug delivery systems for active pharmaceutical ingredients with narrow absorption windows is crucial for improving their bioavailability. This study proposes a novel 3D-printed expandable drug delivery system designed to precisely administer drugs to the upper small intestine, where absorption is most efficient. The aim was to design, prototype, and evaluate the system's functionality for organ retention and targeted drug release.

Background/objectives: Diet composition is important for health, especially during critical periods such as pre-gestation (P), gestation (G), or lactation (S), due to its potential impact not only on the mother but on the offspring. The Mediterranean diet includes many healthy foods rich in fiber and/or polyphenols, such as whole grains, fruits, vegetables, beans, and nuts. The present preclinical study assesses the impact of a diet rich in fiber and polyphenols (HFP diet) during one of those three periods (P, G, or S, three weeks each) on the rat gene expression of the small intestine obtained at the end of the lactation period.

Aromatase plays a crucial role in the conversion of androgens to oestrogens and is often overexpressed in hormone-dependent tumours, particularly breast cancer. [18F]BIBD-071, which has excellent binding affinity for aromatase and good pharmacokinetics, has potential for the diagnosis and treatment of aromatase-related diseases. The MCF-7 cell line, which is hormone receptor-positive (HR+), was used in the assessment of the novel [18F]-labelled radiotracer [18F]BIBD-071 via positron emission tomography (PET) imaging of an HR+ breast cancer xenograft model.

: Medullary carcinoma of the small intestine is an exceptionally rare subtype of gastrointestinal cancer, characterized by its solid growth pattern and lack of glandular structures, which complicate timely diagnosis. During the COVID-19 pandemic, diagnostic delays for rare cancers became increasingly common due to the prioritization of COVID-related cases and patient reluctance to seek medical attention. : We present the case of a 70-year-old male initially misdiagnosed with COVID-19, whose persistent symptoms led to the eventual discovery of medullary carcinoma.
