PGE Binding Affinity of Hemocyte Membrane Preparations of Manduca sexta and Identification of the Receptor-Associated G Proteins in Two Lepidopteran Species.

Prostaglandin E (PGE) is an eicosanoid that mediates a range of physiological actions in vertebrates and invertebrates, including reproduction and immunity. The PGE receptor was identified and functionally assessed in two lepidopteran insects, Manduca sexta and Spodoptera exigua. However, its binding affinity to the receptor has not been reported.

Is the NICE procedure the great equalizer for patients with high BMI undergoing resection for diverticulitis?

Background: By 2030, projections indicate that nearly half of USS adults will be obese, with 29 states exceeding a 50% obesity rate. High Body Mass Index (BMI) presents particular challenges in treating diverticulitis, including worsened symptoms and increased risk of surgical complications. The Robotic Natural orifice Intracorporeal Anastomosis with Transrectal Extraction (NICE) procedure has been developed for colorectal surgeries to tackle these challenges.

A cell line derived from the black soldier fly, Hermetia illucens (Diptera: Stratiomyidae).

Insect cell lines are effective tools used in industry and academia. For example, they are used in screening potential insecticides, in making certain proteins for biomedical applications, and in basic research into insect biology. So far, there are no cell lines derived from the black soldier fly, Hermetia illucens (BSF).

Immunometabolic Adaptation of CD19-Targeted CAR T Cells in the Central Nervous System Microenvironment of Patients Promotes Memory Development.

Unlabelled: Metabolic reprogramming is a hallmark of T-cell activation, and metabolic fitness is fundamental for T-cell-mediated antitumor immunity. Insights into the metabolic plasticity of chimeric antigen receptor (CAR) T cells in patients could help identify approaches to improve their efficacy in treating cancer. Here, we investigated the spatiotemporal immunometabolic adaptation of CD19-targeted CAR T cells using clinical samples from CAR T-cell-treated patients.

The robotic NICE procedure outperforms conventional laparoscopic extracorporeal-assisted colorectal resection: results of a matched cohort analysis.

Introduction: We introduced the robotic NICE procedure for left-sided colorectal resection in 2018 in which the entire procedure is performed without loss of pneumoperitoneum and without an abdominal wall incision by performing natural orifice-assisted transrectal extraction of the specimen and intracorporeal anastomosis. We compare the results of the NICE procedure versus conventional laparoscopic resection, which was our standard approach prior to 2018.

Methods: A matched pair case-control study compared patients following the NICE procedure versus those who underwent laparoscopic left-sided colorectal resection with conventional extracorporeal-assisted technique.

Success rates and outcomes of the robotic NICE procedure across complicated and uncomplicated diverticulitis cases.

Introduction: We implemented the NICE procedure as a robotic natural orifice colorectal resection utilizing the rectum to extract the specimen and complete an intracorporal anastomosis for diverticulitis in 2018. Although complicated diverticulitis is associated with higher rates of conversion and post-operative morbidity, we hypothesized that the stepwise approach of the NICE procedure can be equally successful in this cohort. We aimed to compare feasibility and outcomes of the NICE procedure for uncomplicated and complicated diverticulitis.

Beyond Cellular Immunity: On the Biological Significance of Insect Hemocytes.

Insect immunity is assorted into humoral and cellular immune reactions. Humoral reactions involve the regulated production of anti-microbial peptides, which directly kill microbial invaders at the membrane and intracellular levels. In cellular immune reactions, millions of hemocytes are mobilized to sites of infection and replaced by hematopoiesis at a high biological cost after the immune defense.

The success rate of robotic natural orifice intracorporeal anastomosis and transrectal extraction (NICE procedure) in a large cohort of consecutive unselected patients.

Background: The Robotic NICE procedure is a total intracorporeal natural orifice approach in which specimen extraction and anastomosis is accomplished without an abdominal wall incision other than the port sites themselves. We aim to present the success rate of the NICE procedure in a large cohort of unselected consecutive patients presenting with colorectal disease using a stepwise and reproducible robotic approach.

Methods: Consecutive patients who presented with benign or malignant disease requiring left-sided colorectal resection and anastomosis between May 2018 and June 2021 were evaluated.

Why can insects not biosynthesize cholesterol?

Two aspects of insect lipid biochemistry differ from the mammalian background. In one aspect, nearly a hundred years ago scientists demonstrated that the polyunsaturated fatty acid (PUFAs), linoleic acid (LA; 18:2n-6) is an essential nutrient in the diets of all mammals that have been studied in that regard. An unknown number of insect species are able to biosynthesize LA de novo.

A national evaluation of the predictors of compliance and survival from adjuvant chemotherapy in high-risk stage II colon cancer: A National Cancer Database (NCDB) analysis.

Background: Guidelines recommend adjuvant chemotherapy for stage II colon cancer with high-risk features, but there has been little study on compliance with guidelines. This work sought to evaluate compliance with adjuvant chemotherapy and factors associated with compliance in high-risk stage II colon cancer. This work's hypothesis was that compliance with adjuvant chemotherapy recommendations is low, but improves overall survival when used.

The chemical composition and compound abundance of the propolis samples were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) and the antimicrobial effects were analyzed using the 50% minimum inhibitory concentration (MIC) assay against four relevant bee pathogens, and .

Robotic NICE Procedure Using Handsewn Technique.

Introduction: In 2018, we described a robotic natural orifice-assisted left-sided colorectal resection with intracorporeal anastomosis and transrectal extraction of the specimen and termed it the natural orifice intracorporeal anastomosis with transrectal extraction procedure. More recently, we have explored the feasibility, safety, and utility of performing total handsewn intracorporeal anastomosis. We present a technical video and initial experience depicting the unique steps to accomplish this procedure with colorectal end-to-end handsewn anastomosis.

Single-cell analysis by mass cytometry reveals CD19 CAR T cell spatiotemporal plasticity in patients.

The adaptive T cell immune response requires cellular plasticity to generate distinct subsets with diverse functional and migratory capacities. Studies of CAR T cells have primarily focused on a limited number of phenotypic markers in blood, representing an incomplete view of CAR T cell complexity. Here, we adapted mass cytometry to simultaneously analyze trafficking and functional proteins expression in CD19 CAR T cells across patients' tissues, including leukapheresis T cells, CAR product, CAR T cells in peripheral blood, bone marrow, and cerebrospinal fluid post infusion and correlate them with phenotypes.

The molecular mechanisms by which MEx afford beneficial effects remain incompletely understood. To investigate the therapeutic mechanism of action through assessment of MEx biodistribution and impact on immune cell phenotypic heterogeneity.

A national evaluation of the use and survival impact of adjuvant chemotherapy in Stage II colon cancer from the national cancer database.

Aim: Stage II colon cancers are a heterogeneous category, with controversy over use of adjuvant chemotherapy (AC). Patients with high-risk features may benefit from AC to improve overall survival (OS). Current guidelines do not routinely recommend AC in low-risk cases, but the actual use and benefit on OS in this cohort have not been fully examined on a national scale.

Infections, hospitalisations, and deaths averted via a nationwide vaccination campaign using the Pfizer-BioNTech BNT162b2 mRNA COVID-19 vaccine in Israel: a retrospective surveillance study.

Background: On Dec 20, 2020, Israel initiated a nationwide COVID-19 vaccination campaign for people aged 16 years and older and exclusively used the Pfizer-BioNTech BNT162b2 mRNA COVID-19 vaccine (tozinameran). We provide estimates of the number of SARS-CoV-2 infections and COVID-19-related admissions to hospital (ie, hospitalisations) and deaths averted by the nationwide vaccination campaign.

Methods: In this retrospective surveillance study, we used national surveillance data routinely collected by the Israeli Ministry of Health from the first 112 days (Dec 20, 2020, up to our data cutoff of April 10, 2021) of Israel's vaccination campaign to estimate the averted burden of four outcomes: SARS-CoV-2 infections and COVID-19-related hospitalisations, severe or critical hospitalisations, and deaths.
