Purpose: We present our findings in a case with an intraocular foreign body in which the electroretinographic (ERG) findings were useful.
Observations: A 37-year-old man was injured by an iron fragment that penetrated into his left eye through the cornea. His visual acuity was counting fingers, and a traumatic cataract prevented an examination of the fundus. B-mode ultrasonography showed a stick-like foreign body of approximately 14 mm in length in the eye. Preoperative ERGs with a contact lens electrode showed reduced responses with many blinking artifacts. Lensectomy and pars plana vitrectomy were performed and a fragment of a wire brush was seen embedded in the superior nasal retina which was removed. The decimal visual acuity improved to 1.2 two weeks later. The postoperative ERG performed with a skin electrode showed reduced responses in the injured eye.
Conclusions And Importance: We recommend that the physiology of the retina be assessed by recording ERGs with a skin-type electrode as soon as possible after a traumatic injury to the eye.

Ethnopharmacological Relevance: As digestive health issues rise and interest in natural therapies grows, traditional herbs like Cassia Seed are gaining attention for their antioxidant, laxative, and digestive benefits.
Aim Of The Study: This study aimed to optimize the fermentation conditions of Cassia seed using microbial technology to enhance the content of anthraquinone compounds, thereby augmenting its pharmacological effects, particularly in promoting intestinal peristalsis and alleviating constipation.
Materials And Methods: Fermentation of Cassia Seed was conducted under controlled microbial conditions.
Unlabelled: The gut microbiota influences systemic immunity and the function of distal tissues, including the brain, liver, skin, lung, and muscle. However, the role of the gut microbiota in the foreign body response (FBR) and fibrosis around medical implants is largely unexplored. To investigate this connection, we perturbed the homeostasis of the murine gut microbiota via enterotoxigenic (ETBF) infection and implanted the synthetic polymer polycaprolactone (PCL) into a distal muscle injury.

Unlabelled: The article is devoted to the study of the existing system of training and certification of forensic experts in Ukraine and to the provision of proposals for its modernization, taking into account the positive experience in the field of forensic science of the USA, UK and some countries of the European Union. In Ukraine, the procedure for the training and certification of forensic experts is determined by ministries and other central executive authorities, which manage state specialized institutions that carry out forensic activities. A study of foreign experience in the training and certification of forensic experts made it possible to identify general and specific elements, sustain the benefits of the implemented measures, and formulate priorities and guidelines.

This article presents a novel case of a 16-year-old female who ingested a cigarette lighter, leading to abdominal pain and radiographic confirmation of a gastric foreign body. Initial attempts at retrieval using grasping forceps and snares were unsuccessful due to the object's size and shape, risking potential complications.

Hernia is characterized by the protrusion of organs or tissue through weakened areas in the abdominal cavity wall. A common treatment for hernia involves the implantation of a mesh which promotes the growth of new tissue around or within the implanted material in the damaged area. The mesh is typically made from synthetic materials like polypropylene.
