Force of adhesion between droplets and super-hydrophobic surfaces: Closed-form analytical expressions.

Super-hydrophobic and liquid-repellent surfaces can be characterized experimentally in tensile adhesion experiments with the force (FAdh) required to detach a droplet from such surfaces, but analytical expressions that relate FAdh to the surface energy, w, are still missing. In this work, we derive analytical expressions for FAdh between droplets or radius r and super-hydrophobic surfaces on which the contact angle is greater than 150°. By applying the general condition for the onset of instability in different mechanical configurations, we find FAdh = -πwr and FAdh ≈ -(4/5)πwr, for the fixed-force and fixed-grip configurations, respectively, as well as other expressions that depend on the ratio of the spring constant of a generic force measuring apparatus to the surface tension of the liquid composing the droplet.

SPA14 liposomes combining saponin with fully synthetic TLR4 agonist provide adjuvanticity to hCMV vaccine candidate.

In the aim of designing and developing a novel saponin-based adjuvant system, we combined the QS21 saponin with low microgram amounts of the fully synthetic TLR4 agonist, E6020, in cholesterol-containing liposomes. The resulting adjuvant system, termed SPA14, appeared as a long-term stable and homogeneous suspension of mostly unilamellar and a few multilamellar vesicles, with an average hydrodynamic diameter of 93 nm, when formulated in citrate buffer at pH 6.0-6.

Identifying CD19-targeted CAR-T cell immune pathways in an in vitro human immune mimetic cytokine release assay.

CD19-targeted chimeric antigen receptor-modified T (CAR-T) cells have shown success in clinical studies, with several CD19 CAR-T cell products now having been approved for market use. However, this cell therapy can be associated with side effects such as cytokine release syndrome (CRS). Therefore, pre-clinical test systems are highly desired to permit the evaluation of these unwanted effects before clinical trials begin.

Positivity and Follow-up Testing of Chlamydia trachomatis and Neisseria gonorrhoeae Infections in Universally Screened Female Basic Military Trainees.

Introduction: Follow-up testing is recommended three months after patients initially test positive with Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC). Follow-up testing adherence in the United States has been reported below one third of women, even in universally insured populations. We assessed both the positivity of CT and GC infections in female basic military trainees and the rates of follow-up testing for those who tested positive.

Ectomycorrhizal fungi and the nitrogen economy of in southern Patagonia.

Subantarctic forests are the southernmost forests in the world, with negligible atmospheric nitrogen (N) deposition. Most paradigms about the role of ectomycorrhizal (ECM) fungi in N cycling and plant N uptake at high latitudes have been tested in boreal coniferous forests, while in the southern hemisphere, ECM hosts are primarily angiosperms. Using ITS1 meta-barcoding, we characterized ECM and saprotrophic fungal communities in evergreen and deciduous forests forming monodominant and mixed stands in the archipelago of Tierra del Fuego (Chile and Argentina).

Focal point technology: Controlling treatment depth and pattern of skin injury by a novel highly focused laser.

Background: Selective photothermolysis has limitations in efficacy and safety for dermal targets. We describe a novel concept using scanned focused laser microbeams for precise control of dermal depth and pattern of injury, using a 1550 nm laser that generates an array of conical thermal zones while minimizing injury to the epidermis.

Objective: To characterize the conical thermal zones in vivo and determine safe starting parameters to transition to a second phase to explore potential clinical indications.

Emergency laparotomy and endoscopic gastrostomy in patients on extra-corporeal membrane oxygenation (ECMO) support.

Introduction: An infrequent yet known complication of ECMO is abdominal compartment syndrome requiring emergency laparotomy. Also, the need for prolonged enteral nutrition while on ECMO may require endoscopic gastrostomy to maintain adequate nutritional status. Here we describe our experience with emergency laparotomy and endoscopic gastrostomy in patients on ECMO support.

Intercostal Lung Hernias Presenting After Minimally Invasive Cardiac Surgery.

Introduction: With the introduction of minimally invasive cardiac surgery, more commonly cases of lung herniation are starting to appear. Acquired lung hernias are classified as postoperative, traumatic, pathologic, and spontaneous. Up to 83% of lung hernias are intercostal.

Bilio-Cecal Stent Migration Presenting as Massive Rectal Bleeding.

Endoscopic biliary stenting is a well-established intervention for the treatment of biliary, hepatic, and pancreatic disorders. The common indications include strictures, neoplasms, stones, infections, and bile leaks. Stents can be occluded, predisposing patients to ascending cholangitis and biliary sepsis.

Langmuir monolayers provide an effective strategy for studying molecular recognition of nucleobases using alkylated nucleotides.

Molecular Recognition in nucleotides is crucial for medicine, underpinning precise interactions in genetic replication and therapy. Alkylated nucleotides, in particular, play a key role in modifying DNA to inhibit cancer cell growth. In this study, we focused on an alkylated nucleotide, PNM2 (3',4',6'-O-tristearoyl uridine or uridine tri-stearate), to investigate the interaction between adenine molecules in the aqueous subphase and PNM2 Langmuir monolayers.

Gut microbiome diversity within is negatively associated with human obesity.

Unlabelled: are abundant in the human gut and comprise families associated with host health such as which has been correlated with leanness. However, culturing bacteria within this family is challenging, leading to their detection primarily through 16S rRNA amplicon sequencing, which has a limited ability to unravel diversity at low taxonomic levels, or by shotgun metagenomics, which is hindered by its high costs and complexity. In this cross-sectional study involving 114 Colombian adults, we used an amplicon-based sequencing strategy with alternative markers-gyrase subunit B () and DNA K chaperone heat protein 70 ()-that evolve faster than the 16S rRNA gene.

Exploring the physicochemical properties of the integration of Tristearoyl uridine in Langmuir monolayers: An approach to cell membrane modeling for prodrugs.

Understanding the mechanisms by which drugs interact with cell membranes is crucial for unraveling the underlying biochemical and biophysical processes that occur on the surface of these membranes. Our research focused on studying the interaction between an ester-type derivative of tristearoyl uridine and model cell membranes composed of lipid monolayers at the air-water interface. For that, we selected a specific lipid to simulate nontumorigenic cell membranes, namely 1,2-dihexadecanoyl-sn-glycero-3-phospho-l-serine.

A three-phase algorithm for the pollution traveling Salesman problem.

This paper studies a variant of the Pollution Traveling Salesman Problem (PTSP) focused on fuel consumption and pollution emissions (PTSPC). The PTSPC generalizes the well-known Traveling Salesman Problem (TSP), classified as NP-Hard. In the PTSPC, a vehicle must deliver a load to each customer through a Hamiltonian cycle, minimizing an objective function that considers the speed of each edge, the mass of the truck, the mass of the load pending delivery, and the distance traveled.
