Background: Level of lymph nodes dissection (LND) and inferior mesenteric artery (IMA) ligation is still matter of debate of radical resection of colorectal cancer. This study aims to compare the short-term outcome of three different surgical techniques to treat sigmoid cancer: low ligation (LL) of the IMA with D3-LND, low IMA ligation with D2-LND, and high ligation (HL) of the IMA with D3-LND.

Methods: Patients affected by sigmoid colon cancer, who underwent radical resection with three different techniques (LL and D3-LND Group A, HL and D3-LND Group B, and LL with D2 LND- Group C), were included.

Background: Research has consistently highlighted the key role of hepatocyte nuclear factor 1β (HNF1B) in organ development and cancer, including its involvement in colon cancer via shifted-code mutations. However, the specific effects of HNF1B on cancer immunotherapy and the immune microenvironment are not fully understood. This study investigated the impact of HNF1B on colon cancer immunotherapy in depth.

Department of general surgery (intestinal surgery), The Sixth Affiliated Hospital, Sun Yat-Sen University, 26 Yuancun Erheng Rd, Guangzhou, 510655, Guangdong, People's Republic of China.

In hepatic flexure and transverse colon cancer surgeries, mobilizing the right mesocolon and precisely dissecting the gastrocolic trunk of Henle (GTH) are crucial. Previous classifications of GTH tributaries do not guide radical right hemicolectomy due to post-procedural anatomical acquisition. This study analyzed vessel associations, including the middle colic vein (MCV) converging site, right colic artery (RCA) presence, and other GTH tributaries, using ultra-thin CT for reconstruction.

Crohn's disease (CD) is a chronic inflammatory bowel condition, and colon adenocarcinoma (COAD), as one of the most prevalent malignant tumors of the digestive tract, has been indicated by research to have a close association with CD. This study employs bioinformatics techniques to uncover the potential molecular links between CD and COAD. In this study, two data series related to CD were identified from the Gene Expression Omnibus (GEO) database under specific criteria, and relevant COAD gene data were obtained from The Cancer Genome Atlas (TCGA).

To understand the action mechanism of probiotics against postmenopausal symptoms, we examined the effects of Lactococcus lactis P32 (P) and Bifidobacterium bifidum P45 (P), which suppressed interleukin (IL)-6 and receptor activator of nuclear factor-κB (RANK) ligand (RNAKL) expression in Gardnerella vaginalis (Gv)-stimulated macrophages, on vaginitis, osteoporosis, and depression/cognitive impairment (DC) in mice with vaginally infected Gv, ovariectomy (Ov), or Ov/Gv (oG). Oral administration of P or P decreased Gv-induced DC-like behavior and tumor necrosis factor (TNF)-α, IL-6, RANK, and/or RANKL expression in the vagina, bone, hypothalamus, hippocampus, and colon, while Gv-suppressed bone osteoprotegerin and brain serotonin and brain-derived neurotrophic factor (BDNF) levels increased. They partially shifted vaginal and gut dysbiosis in Gv-infected mice to the gut microbiota composition in normal control mice.

A simple model of the rheological curve of HPAM solutions at different temperatures.

Sci Rep

December 2024

Laboratorio de Fluidodinámica, Facultad de Ingeniería, Universidad de Buenos Aires/CONICET, Paseo Colón 850 CABA, Buenos Aires, Argentina.

Article Synopsis
  • The oil and gas industry is grappling with climate change and resource depletion, prompting a shift towards enhanced recovery methods like polymer flooding, which boasts higher recovery rates and lower emissions.
  • Existing physical models for predicting polymer flooding outcomes need improvement, particularly in accurately modeling the flow behavior of polymer solutions.
  • The new PAMA-T model expands the original PAMA technique to make it applicable across a wider temperature range (298-343 K), enabling better predictions of rheological properties using minimal data input from viscosity measurements.

The potential for mitigating intestinal inflammation through the gut-bone axis in the treatment of osteoporosis is significant. While various gut-derived postbiotics or bacterial metabolites have been created as dietary supplements to prevent or reverse bone loss, their efficacy and safety still need improvement. Herein, a colon-targeted drug delivery system is developed using surface engineering of polyvinyl butyrate nanoparticles by shellac resin to achieve sustained release of postbiotics butyric acid at the colorectal site.

we report the case of a recurrent giant pseudopolyp occurring in a patient without a history of inflammatory bowel disease (IBD), with an asymptomatic interval of nine years. Case Presentation: a 51-year-old Caucasian male with no relevant medical history was hospitalized for a subocclusive mass in the right colon, suspected to be neoplastic. He underwent a right hemicolectomy, and the histopathology revealed a giant pseudopolyp without malignancy.

tumour specific surgery in colon cancer is gaining popularity among colorectal surgeons. Many advocate adapting surgical technique based on preoperative CT staging as not all patients require complete mesocolic excision (CME) and D3 lymphadenectomy. We aimed to assess the sensitivity and specificity of preoperative CT scans in nodal staging and analyse whether inadequate CT staging could have influenced local recurrences.

Despite the variety of proposed solutions, anastomotic leakage is still a critical complication after colorectal surgery, which causes increased clinical mortality and morbidity. By enhancing microcirculation in the colonic mucosa, the use of Iloprost (Ilo) has shown promising results for the healing of anastomosis. The purpose of this study is to examine the performance of Ilo-impregnated Polycaprolactone:Gelatin electrospun membranes (PCL/Gel/Ilo) on anastomosis repair and intra-abdominal adhesion behavior in the Rat colon.

Objective: Colorectal cancer is severely challenging because of the insufficient understanding of the mechanism underlying its resistance to clinical chemotherapy. The purpose of our study is to investigate the role of the LIM protein Ajuba (JUB) in the chemoresistance of colon cancer and its potential effect on clinical treatment.

Material And Methods: The protein levels of JUB in colon cancer tissues were evaluated using Western blot analysis and immunohistochemistry assays.

Aim: To assess recent colonoscopies and CT scans in conjunction with the feacal immunochemical test (FIT) for possibly downgrading urgent suspected cancer (USC) referrals.

Methods:  A retrospective single-centre study was conducted, including all USC referrals for colonoscopy in 2022, excluding anal cancers. The CT and colonoscopy findings for a two-year period prior to the referral, along with the FIT result (if done), were noted.

Colonic epithelium is situated above a layer of fibroblasts that provide supportive factors for stem cells at the crypt base and promote differentiation of cells in the upper crypt and luminal surface. To study the fibroblast-epithelial cell interactions, an crypt model was formed on a shaped collagen scaffold with primary epithelial cells growing above a layer of primary colonic fibroblasts. The crypts possessed a basal stem cell niche populated with proliferative cells and a differentiated, nondividing cell zone at the luminal crypt end.
