AI Article Synopsis
- Research on splenic resections in rats shows that the remaining spleen undergoes compensatory hyperplasia rather than true regeneration after hemisplenectomy.
- The residual spleen's weight increases moderately but only temporarily during the year following the procedure.
- Human scintigraphic studies align with rat findings, indicating that the residual splenic tissue maintains its shape without volume increase one year post-surgery.
Article Abstract
The increased experience in the field of splenic resections have brought up questions about the evolution of the residual parenchyma. Weight increase and the histologic structure of the splenic remnant were studied during a year following hemisplenectomy in rats. Histological studies show that the residual spleen presents a permanent compensatory hyperplasia rather than a true regeneration. This hyperplasia causes an increase in weight of the residual parenchyma which is moderate and only transitory. Indirect confirmation of findings obtained in rats comes from scintigraphic study of residual human splenic tissue after hemisplenectomy. The residual tissue keeps its original form without increase in volume, and the sectioned surface is always well identified one year after splenic resection.

Methylcobalamin-containing nanofiber sheets have better neuroprotective effects than small intestinal submucosa sheets.

Postoperative adhesion around nerves sometimes results in sensory and motor dysfunctions. To prevent these disorders, we have developed an electrospun nanofiber sheet incorporating methylcobalamin (MeCbl), an active form of vitamin B12 with anti-inflammatory and neuroregenerative effects. This study aimed to investigate the neuroprotective effects of MeCbl sheets against postoperative adhesion and to compare the effects of MeCbl sheets with those of porcine small intestinal submucosa (SIS) sheets using a rat sciatic nerve adhesion model.

Background/aim: Lipoprotein(a) (Lp(a)) is a complex protein involved in the transport of insoluble lipids in plasma. Its expression is predominantly genetically determined, with 70% to over 90% influenced by the number of Kringle IV type 2 domains. This study investigated the association between preoperative serum Lp(a) level and development of post-pancreatectomy nonalcoholic fatty liver disease (NAFLD) in patients who underwent pancreatectomy.

Background: Despite advances in reperfusion therapies, ischemic stroke remains a major cause of long-term disability due to residual hypoxic lesions persisting after macrovascular reperfusion. These residual hypoxic lesions, caused by microvascular dysfunction, represent an important therapeutic target. We previously demonstrated that oxygen-glucose-deprived peripheral blood mononuclear cells (OGD-PBMCs) migrate to ischemic brain regions and promote functional recovery after stroke.

Background: Perioperative chemotherapy is the standard of care for patients with locally advanced gastric and gastroesophageal junction cancer. Recent evidence demonstrated the addition of programmed cell death protein 1 (PD-1) inhibitors enhanced therapeutic efficacy. However, the mechanisms of response and resistance remain largely undefined.

Unlabelled: Thoracic endometriosis syndrome (TES) is a rare condition where endometrial tissue is found in the pleura, parenchyma, and/or diaphragm. Haemoptysis is a common manifestation of pulmonary endometriosis and can be cyclic, aligning with the menstrual cycle. Patients can present with residual cough once menses have stopped.
