Bezoars, characterized by undigested or partially digested foreign bodies in the gastrointestinal (GI) tract, are a rare condition associated with significant complications. We present a case of a 31-year-old woman who sought medical attention due to weight loss, diarrhea, and anorectal pain. Upon investigation, she was diagnosed with fecal impaction caused by a rectal sunflower seed bezoar. The patient had a history of regular sunflower seed consumption, suggesting a potential association with the development of the bezoar. Fecal impaction resulting from the bezoar led to chronic constipation, contributing to the patient's weight loss and anorectal discomfort. Imaging studies, including abdominal X-rays or computed tomography (CT) scans, played a crucial role in confirming the diagnosis by identifying the presence of the bezoar within the rectum. Management involved a multidisciplinary approach, with gastroenterologists and colorectal surgeons. A flexible endoscope was utilized to visualize and remove the sunflower seed bezoar under direct vision, providing immediate relief from the symptoms. This case emphasizes the importance of considering bezoars as a potential cause of GI symptoms, even in young and otherwise healthy individuals. Although rectal bezoars are relatively rare, they can lead to significant morbidity. Therefore, it is essential to include them in the differential diagnosis of patients presenting with fecal impaction, anorectal pain, and associated symptoms. Prompt diagnosis, appropriate imaging, and early intervention are crucial for the successful management and prevention of potential complications and the improvement of patient outcomes.

Leaf senescence in plants is the last stage of leaf development and is characterized by a decline in photosynthetic activity, an active degeneration of cellular structures, and the recycling of accumulated nutrients to areas of active growth, such as buds, young leaves, flowers, fruits, and seeds. This process holds economic significance as it can impact yield, influencing the plant's ability to maintain an active photosynthetic system during prolonged periods, especially during the grain filling stage, which affects plant weight and oil content. It can be associated with different stresses or environmental conditions, manifesting itself widely in the context of climate change and limiting yield, especially in crops of agronomic relevance.

A sunflower seed shell matrix catalyst (SMS-750) was prepared from sunflower seed shell waste by pretreatment and pyrolytic carbonization. A series of characterization analyses showed that the prepared catalyst was rich in Ca, Mg, K, and other mineral elements and mainly existed in the form of metal oxides. SMS-750 was used to catalyze the glycolysis of waste PET, and the main factors affecting the BHET yield were screened out by a one-way experimental design, and then the BHET yield was used as the response value, and the response surface method was used to design and analyze the effects of the respective variables and their interactions on the degradation of PET according to the principle of Box-Behnken central combinatorial design.

Nanoparticles play a significant role in enhancing crop yield and reducing nutrient loss through precise nutrient delivery mechanisms. However, it is imperative to ascertain the specific plant physiology altered by these nanoparticles. This study investigates the effects of green-synthesized nanoparticles, specifically boron nitride and sulphur, on sunflower yield, seed quality, and physiological activities.

Insects provide important pollination services for cops. While land use intensification has resulted in steep declines of wild pollinator diversity across agricultural landscapes, releasing managed honeybees has been proposed as a countermeasure. However, it remains uncertain whether managed honeybees can close the pollination gap of sunflower (Helianthus annuus L.

The Pseudomonas aeruginosa LasR quorum sensing system (QSS) is central to regulating the expression of several pathogenicity factors. Also, while seed- and/or plant-derived products have been investigated as QSS regulators, the impact of Helianthus annuus (Pannar sunflower seed cultivars) extracts and metabolites as LasR modulators remain underexplored. Thus, this study focused on the untargeted metabolomic profiling (Liquid Chromatography-Mass Spectrometry), in vitro and in silico (docking, pharmacokinetics, dynamic simulation) bioprospection of Pannar seed cultivars' extracts and metabolites as LasR modulators.
