Recent research exploring the relationship between the gut and the brain suggests that the condition of the gut microbiota can influence cognitive health. A well-balanced gut microbiota may help reduce inflammation, which is linked to neurodegenerative conditions. Prebiotics, probiotics, and symbiotics are nutritional supplements and functional food components associated with gastrointestinal well-being.

In this paper, a new structural steel shape is proposed to be used in composite columns. The model is made of a concrete column with the proposed steel section embedded in concrete with four angles "L shape", welded together to form the shape "X". The equivalent compressive strength capacity of this "X" shape was compared to the conventional steel "W shape" section.

Effects of Nanoparticle Wettability on the Meniscus Stability of Oil-Water Systems: A Coarse-Grained Modeling Approach.

J Phys Chem B

March 2024

School of Sustainable Chemical, Biological and Materials Engineering, The University of Oklahoma, 100 East Boyd Street, Norman, Oklahoma 73019, United States.

A coarse-grained modeling approach is employed to probe the effect of nanoparticles and their wettability on the stability of the interface between two immiscible fluids. In this study, pure oil (dodecane) and water are placed side by side in a nanochannel, forming a meniscus. Homogeneous hydrophilic nanoparticles, Janus particles, and homogeneous hydrophobic nanoparticles are placed at the oil-water interface, and their dynamics are studied as they rearrange at the oil-water interface.

Modified Chalazion Clamp: Novel Applications in Dermatologic Surgery.

J Clin Aesthet Dermatol

March 2024

Dr. Khachemoune is with the Department of Dermatology at SUNY Downstate in Brooklyn, New York. Additionally, Dr. Khachemoune is with the Department of Dermatology at Veterans Affairs New York Harbor Healthcare System in Brooklyn, New York.

Biopsies and excisions of mucosal surfaces can be challenging due to poor visualization and bleeding control. Surgeons have utilized chalazion clamps to overcome these challenges. However, its original design incorporates a locking mechanism which restricts its use to more proximal mucosal surfaces, does not allow for flexible exertional pressure control by the operator, and it is only available in one size.

Biodistribution and therapeutic efficacy of a gold nanoparticle-based targeted drug delivery system against pancreatic cancer.

Cancer Lett

May 2024

Department of Pathology, University of Oklahoma Health Sciences Center, Oklahoma City, OK, 73104, USA; Peggy and Charles Stephenson Cancer Center, The University of Oklahoma Health Sciences Center, Oklahoma City, OK 73104, USA. Electronic address:

Pancreatic cancer is characterized by desmoplasia; crosstalk between pancreatic cancer cells (PCCs) and pancreatic stellate cells (PSCs) leads to the deposition of extracellular matrix proteins in the tumor environment resulting in poor vascularity. Targeting either PCCs or PSCs individually has produced mixed results, and there is currently no effective strategy to target both cell types simultaneously. Previously, we demonstrated, through in vitro cell culture experiments, that a specific gold nanoparticle-based nanoformulation containing the anti-EGFR antibody cetuximab (C225) as a targeting agent and gemcitabine as a chemotherapeutic agent effectively targets both PCCs and PSCs simultaneously.

Unlabelled: TcdB is an intracellular bacterial toxin indispensable to infections. The ability to use chondroitin sulfate proteoglycan 4 (CSPG4) as a primary cell surface receptor is evolutionarily conserved by the two major variants of TcdB. As CSPG4 does not typically undergo receptor-mediated endocytosis, we sought to identify environmental factors that stabilize interactions between TcdB and CSPG4 to promote cell binding and entry into the cytosol.

Objectives: Allogeneic haematopoietic cell transplant (allo-HCT) recipients who are cytomegalovirus (CMV)-seronegative have better post-transplant outcomes than CMV-seropositive recipients. Letermovir (LTV) is approved for CMV primary prophylaxis in adults who are CMV-seropositive after allo-HCT, and its use is associated with improved long-term post-transplant outcomes. We analysed whether LTV has affected the relationship between CMV serostatus and post-transplant outcomes.

Article Synopsis
  • This analysis investigates whether patients with peripheral artery disease (PAD) benefit more from taking ticagrelor alone or in combination with aspirin after undergoing a procedure called percutaneous coronary intervention (PCI).
  • The TWILIGHT trial involved patients at high risk for heart issues or bleeding, who were given either aspirin or a placebo alongside ticagrelor after 3 months of dual antiplatelet therapy, with outcomes assessed after 12 months.
  • Results showed that while PAD patients faced higher risks of complications, those on ticagrelor monotherapy experienced fewer bleeding complications compared to those on combination therapy, without a rise in heart attack or stroke incidents.

Importance: Combination androgen deprivation therapy (ADT) with radiotherapy is commonly used for patients with localized and advanced prostate cancer.

Objective: To assess the efficacy and safety of the oral gonadotropin-releasing hormone antagonist relugolix with radiotherapy for treating prostate cancer.

Design, Setting, And Participants: This multicenter post hoc analysis of patients with localized and advanced prostate cancer receiving radiotherapy in 2 randomized clinical trials (a phase 2 trial of relugolix vs degarelix, and a subset of the phase 3 HERO trial of relugolix vs leuprolide acetate) included men who were receiving radiotherapy and short-term (24 weeks) ADT (n = 103) from 2014 to 2015 and men receiving radiotherapy and longer-term (48 weeks) ADT (n = 157) from 2017 to 2019.

Article Synopsis
  • - Patients with paraneoplastic syndromes (PNS) are often excluded from clinical trials for immune checkpoint inhibitors (ICIs) due to potential safety risks, leading to a lack of real-world data on their efficacy and safety for these patients.
  • - A study analyzed data from 109 PNS patients with solid tumors treated with ICIs between 2015 and 2022, finding that 29% of those with pre-existing PNS experienced exacerbations shortly after starting ICI therapy, and a significant portion required immunosuppressive treatment.
  • - No significant differences in overall survival (OS) or time-to-next treatment (TTNT) were observed between patients with metastatic non-small cell lung cancer (mNSCLC) with P

  • The study aimed to assess the effectiveness and safety of a combination therapy using mirvetuximab soravtansine (MIRV), carboplatin, and bevacizumab for patients with recurrent, platinum-sensitive ovarian cancer.
  • In a trial with 41 participants, results showed a high objective response rate of 83%, with a median duration of response of 10.9 months and progression-free survival of 13.5 months.
  • Although adverse events were common, they were mostly mild to moderate, with thrombocytopenia being the main reason for dose adjustments, indicating the combination therapy was both active and tolerable.

Background: Immunotherapy has transformed the endometrial cancer treatment landscape, particularly for those exhibiting mismatch repair deficiency [MMRd/microsatellite instability-hypermutated (MSI-H)]. A growing body of evidence supports the integration of immunotherapy with chemotherapy as a first-line treatment strategy. Recently, findings from ongoing trials such as RUBY (NCT03981796), NRG-GY018 (NCT03914612), AtTEnd (NCT03603184), and DUO-E (NCT04269200) have been disclosed.

Article Synopsis
  • - The study compared traditional soiled-bedded sentinels (SBSs) to newer PCR testing methods for monitoring colony health in mice by examining dust from exhaust filters.
  • - Researchers used 25 mouse racks and collected exhaust dust from two filter types: exhaust dust test (EDT) and SBS cage-level exhaust filter (SCEF), finding that SCEF detected pathogens more frequently.
  • - Results indicated that both PCR testing methods were more effective than SBS for detecting pathogens, supporting the institution's shift toward environmental monitoring for rodent health surveillance.

Introduction: The prevalence of both obesity and gestational diabetes mellitus (GDM) has increased, and each is associated with adverse perinatal outcomes including fetal overgrowth, neonatal morbidity, hypertensive disorders of pregnancy and caesarean delivery. Women with GDM who are also overweight or obese have higher rates of pregnancy complications when compared with normal-weight women with GDM, which may occur in part due to suboptimal glycaemic control. The current recommendations for glycaemic targets in pregnant women with diabetes are based on limited evidence and exceed the mean fasting (70.
