Transmembrane uptake of polystyrene nanoplastics mediated by aquaporin in tartary buckwheat: Physiological consequence and genomic mechanism.

It is still unclear how polystyrene nanoplastics (Ps-NPs) go through plant cell, and its physiological consequence and molecular mechanisms. To address this issue, the seedlings of tartary buckwheat (Fagopyrum tataricum) were exposed to hydroponic solution with 100 mg/L fluorescent-labeled Ps-NPs (100-nm diameter) across 0-2-4-6-8 days. Laser confocal microscopy, scanning electron microscopy and transmission electron microscope illuminated that Ps-NPs can go through root cells and cause significant physiological responses with time.

Association Between Constipation and a Reduction in Lower Limb Muscle Strength in Preoperative Patients with Thoracic Spinal Tumors.

Objective To investigate the clinical symptoms experienced by patients with thoracic spinal tumors and verify the associated symptoms that are predictive of a decline in muscle strength in the lower limbs. Methods A single-center, retrospective cross-sectional study was conducted on in-patients diagnosed with epidural thoracic spinal tumors between January 2011 and May 2021. The study involved a review of electronic medical records and radiographs and the collection of clinical data.

Fibroblast growth factor 21 ameliorates neurodegeneration in rat and cellular models of Alzheimer's disease.

Our understanding of the mechanisms underlying process in Alzheimer's disease (AD) is far from completion and new therapeutic targets are urgently needed. Recently, the link between dementia and diabetes mellitus (DM) prompted us to search for new therapeutic strategies from glucose metabolism regulators for neurodegeneration. Previous studies have indicated that fibroblast growth factor 21 (FGF21), an attractive and potential therapeutic treatment for DM, may exert diverse effects in the central nervous system.

Outcomes of endoscopic and microscopic transsphenoidal surgery on non-functioning pituitary adenomas: a systematic review and meta-analysis.

Both microscopic and endoscopic transsphenoidal surgery are effective approaches for nonfunctioning pituitary adenomas. The issue on the comparison of their efficacy and safety remains inconsistent. A thorough search of the literatures (PubMed, EMBASE, MEDLINE) were performed up to March 2017.

Outcomes of laparoscopic management of acute small bowel obstruction: a 7-year experience of 110 consecutive cases with various etiologies.

Purpose: Laparoscopic surgery is emerging as an alternative to open surgery for treating acute small bowel obstruction (SBO). While postoperative adhesion is the most frequent etiology, the optimum treatment for all types of SBO needs to be evaluated.

Methods: A retrospective review was performed of 110 consecutive patients who underwent laparoscopic surgery at our institution between 2009 and 2015.

Endovascular Stenting for Non-Traumatic Celiac Artery Stenosis Following Pancreatoduodenectomy.

Postoperative celiac artery stenosis (CAS) rarely occurs in the absence of vascular injury or pseudoaneurysm after pancreatoduodenectomy (PD). Because of its low incidence, the optimal treatment for non-traumatic postoperative CAS is unknown. Here, we show a case of CAS possibly due to exacerbated median arcuate ligament compression after PD.

Minimally invasive surgery for superior mesenteric artery syndrome: A case report.

Superior mesenteric artery (SMA) syndrome is defined as a compression of the third portion of the duodenum by the abdominal aorta and the overlying SMA. SMA syndrome associated with anorexia nervosa has been recognized, mainly among young female patients. The excessive weight loss owing to the eating disorder sometimes results in a reduced aorto-mesenteric angle and causes duodenal obstruction.

An unusual case of duodenal perforation caused by a blister pack: A case report and literature review.

Introduction: Ingestion of foreign bodies is a relatively common clinical problem. Blister packs have been known to be a causative agent of gastrointestinal perforation. We report a rare case of duodenal perforation caused by a blister pack, which was complicated by retroperitoneal abscess and having a poor outcome.

Reduced port laparoscopic surgery for colon cancer in a patient with tuberculous kyphosis and dwarfism: a rare case and literature review.

With accumulated surgical experience, the contraindications to laparoscopic surgery have been decreasing. Reduced port laparoscopic surgery has been widely adopted for a variety of diseases. However, surgery in patients with anatomic deformities are still a challenge for surgeons, specifically abdominal surgery in patients with severe kyphosis.

Pneumatosis cystoides intestinalis associated with toxic epidermal necrolysis: A case report.

Toxic epidermal necrolysis (TEN) is a severe adverse drug reaction, which is characterized by erythema, blisters, and/or erosions of the mucous membranes and skin, but intestinal involvement is rare. In contrast, pneumatosis cystoides intestinalis (PCI) is a rare condition associated with a wide variety of underlying diseases, but to date no patient has presented with PCI associated with TEN. A 55-year-old man was admitted to intensive care unit for treatment of TEN caused by phenobarbital.
