Peripherial iv

INTRODUCTION AND IMPORTANCE: An uncontrolled hyperglycaemia accompanied by metabolic acidosis and an increase in total body ketone, if left untreated, has the potential to develop into complications, including diabetes ketoacidosis (DKA). Management of this complication with IV hydration, IV Insulin, and potassium (KCL) maintenance is a comprehensive approach. On the contrary, bicarbonate therapy is generally not regarded as a standard treatment due to its unfavourable outcome. CASE PRESENTATION: The authors present a case of a 21-year-old female who was brought in a semiconscious state to the emergency department with complaints of pain in the abdomen, headache, and vomiting...

We developed a comprehensive mathematical model of cancer immunotherapy that takes into account: i) Immune checkpoint blockers (ICBs) and the interactions between cancer cells and the immune system, ii) characteristics of the tumor microenvironment, such as the tumor hydraulic conductivity, interstitial fluid pressure, and vascular permeability, iii) spatial and temporal variations of the modeled components within the tumor and the surrounding host tissue, iv) the transport of modeled components through the vasculature and between the tumor-host tissue with convection and diffusion, and v) modeling of the tumor draining lymph nodes were the antigen presentation and the development of cytotoxic immune cells take place...

PURPOSE: GS-3583, a FMS-like tyrosine kinase 3 (FLT3) agonist Fc fusion protein, expanded conventional dendritic cells (cDCs) in the periphery of healthy volunteers, suggesting potential for GS-3583 to increase cDCs in the tumor microenvironment and promote T cell-mediated antitumor activity in cancer patients. This phase Ib open-label study assessed GS-3583 in adults with advanced solid tumors. PATIENTS AND METHODS: Multiple escalating doses of GS-3583 (standard 3+3 design) were administered intravenously on days 1 and 15 of cycle 1 and day 1 of each subsequent 28-day cycle for up to 52 weeks...

OBJECTIVE: Demonstrate the usefulness of using indocyanine green after laparoscopic ovarian detorsion to save the ovary. DESIGN: A step-by-step video demonstration of a surgical technique. SETTING: Ovarian torsion is one of the most common gynecological emergencies, mainly affecting patients younger than 20 years of age [1], and causes 2% to 7% of acute abdomens [2]. It is not advisable to routinely perform ovariectomy even with a necrotic ovary appearance [1]...

A female patient in her 60s with a history of Parkinson's disease developed epigastric and retrosternal chest pain, with associated vomiting. On examination, she had a distended abdomen with no focal peritonism. A computed tomography (CT) pulmonary angiogram was organized, which demonstrated no evidence of pulmonary emboli, but an incidental finding of gas within the liver peripheries and gastric fundal wall. A plain film abdominal radiograph demonstrated a significantly distended stomach. Thus, acute gastric dilatation was diagnosed...

Xylazine, a veterinary tranquillizer known by drug users as "Tranq", is being increasingly detected in people who overdose on opioid drugs, indicating enhanced health risk of fentanyl-xylazine mixtures. We recently found that xylazine potentiates fentanyl- and heroin-induced brain hypoxia and eliminates the rebound-like post-hypoxic oxygen increases. Here, we used oxygen sensors coupled with high-speed amperometry in rats of both sexes to explore the treatment potential of naloxone plus atipamezole, a selective α2-adrenoceptor antagonist, in reversing brain (nucleus accumbens) and periphery (subcutaneous space) hypoxia induced by a fentanyl-xylazine mixture...

In dairy cows, the lactating mammary glands synthesize serotonin, which acts in an autocrine-paracrine manner in the glands and is secreted into the periphery. Serotonin signaling during lactation modulates nutrient metabolism in peripheral tissues such as adipose and liver. We hypothesized that the elevation of circulating serotonin during lactation would increase nutrient partitioning to the mammary glands, thereby promoting milk production. Our objective was to elevate circulating serotonin via intravenous infusion of the serotonin precursor 5-hydroxytryptophan (5-HTP) to determine its effects on mammary supply and extraction efficiency of AA, and milk components production...

PURPOSE: We describe a case of relentless placoid chorioretinitis that was responsive to intravitreal triamcinolone (IVT) and systemic adalimumab, but suboptimally responsive to oral prednisone. METHODS: Interventional case report. RESULTS: A 23-year-old woman presented with macular placoid chorioretinitis in the left eye and visual acuity of finger counting at 3 feet. Despite a 2-week course of 60mg oral prednisone, the choroiditis expanded dramatically in the mid-periphery...

Heterozygous mutation of PAX6 in humans leads to congenital aniridia (OMIM 106210) which is typified by congenital iris and foveal defects, and later onset glaucoma, aniridic keratopathy, and cataract. Mice heterozygous for Pax6 mutations phenocopy many aspects of aniridia including the iris defects, keratopathy and cataract, although Pax6 mutant mice have small lenses, a phenotype which is not typically reported in human aniridia, perhaps due to difficulties in measuring lens diameter during typical ophthalmic examinations as the lens periphery is shielded by the iris...

ConspectusHierarchical helicates are formed by noncovalent connection of two or more monomeric metal complex units, e.g., by bridging metal cations. A unique kind of hierarchical helicate is obtained from 3-carbonyl substituted catechol ligands with titanium(IV) ions in the presence of lithium cations. This kind of supramolecular complex shows in solution a "monomer-dimer" equilibrium. There are different possibilities (solvent, countercation, substituents at carbonyl unit, etc.) to shift this equilibrium to either the monomer or the dimer side...

We report the choroidal and ciliary body invasion by retinoblastoma (RB) in a salvaged eye after complete and successful primary treatment. Case 1: A 25-month-old boy was referred due to group B RB lesions based on the International Classification of RB (ICRB; groups A-E) in the right eye (OD). His left eye (OS) was enucleated because of advanced group E RB. After 47 months of uneventful follow-up (F/U), a new lesion recurred and was treated with transpupillary thermotherapy. Four months later, a fast-growing pigmented subretinal mass was detected that was treated by brachytherapy with the apical dose of 80 Gy...

Selective T-cell depletion prior to cell or organ transplantation is considered a preconditioning regimen to induce tolerance and immunosuppression. An immunotoxin consisting of a recombinant anti-CD3 antibody conjugated with diphtheria toxin was used to eliminate T-cells. It showed significant T-cell depletion activity in the peripheral blood and lymph nodes in animal models used in previous studies. To date, a comprehensive evaluation of T-cell depletion and CD3 proliferation for all lymphoid tissues has not been conducted...

An otherwise healthy 17-year-old male patient presented to a periphery hospital with a compound fracture of the right distal tibia and fibula after a traumatic accident on a ski trip. He was treated empirically with IV cefazolin before undergoing open reduction with internal fixation with intramedullary nail for surgical fixation. Postoperatively, he became febrile, tachypneic, and hypoxemic, requiring up to 6 L/min supplemental oxygen by nasal prongs. He reported mild chest discomfort but denied productive cough, hemoptysis, or calf tenderness...

The relative positions of viral DNA genomes to the host intranuclear environment play critical roles in determining virus fate. Recent advances in the application of chromosome conformation capture-based sequencing analysis (3C technologies) have revealed valuable aspects of the spatiotemporal interplay of viral genomes with host chromosomes. However, to elucidate the causal relationship between the subnuclear localization of viral genomes and the pathogenic outcome of an infection, manipulative tools are needed...

MATERIALS AND METHODS: The clinical material of the study was 12 patients with phlegmon of MFR who were being treated in the maxillofacial department of the N.I. Pirogov State Clinical Hospital No...

The biological influence of physicochemical parameters of "targeted" nanoparticles on their delivery to cancer tumors remains poorly understood. A comparative analysis of nanoparticle distributions in tumors following systemic delivery across several models can provide valuable insights. Methods: Bionized nanoferrite nanoparticles (iron oxide core coated with starch), either conjugated with a targeted anti-HER2 antibody (BH), or unconjugated (BP), were intravenously injected into athymic nude or NOD-scid gamma (NSG) female mice bearing one of five human breast cancer tumor xenografts growing in a mammary fat pad...

Neurodegeneration and cerebrovascular disease share an underlying microvascular dysfunction that may be remedied by selective transgene delivery. To date, limited options exist in which cellular components of the brain vasculature can be effectively targeted by viral vector therapeutics. Here, we characterize the first engineered adeno-associated virus (AAV) capsid mediating high transduction of cerebral vascular pericytes and smooth muscle cells. We performed two rounds of in vivo selection with an AAV capsid scaffold displaying a heptamer peptide library to isolate capsids that traffic to the brain after intravenous (iv) delivery...

Toxoplasma gondii is an obligate intracellular parasite of the phylum Apicomplexa and causes toxoplasmosis infections, a disease that affects a quarter of the world's population and has no effective cure. Epigenetic regulation is one of the mechanisms controlling gene expression and plays an essential role in all organisms. Lysine deacetylases (KDACs) act as epigenetic regulators affecting gene silencing in many eukaryotes. Here, we focus on TgKDAC4, an enzyme unique to apicomplexan parasites, and a class IV KDAC, the least-studied class of deacetylases so far...

This comparative study was conducted to assess the intramedullary bone tissue reaction of an ion-releasing resin modified glass-ionomer cement with claimed bioactivity (ACTIVA bioactive resin) restorative material versus Mineral Trioxide Aggregate High Plasticity (MTA HP) and bioceramic putty iRoot BP Plus. Fifty-six adult male Wistar rats were assigned into 4 equal groups (14 rats each). A surgical intramedullary bi-lateral tibial bone defects were performed in rats of the control group I (GI) and left without any treatment to be considered as controls (n = 28)...

This study reports the synthesis and characterization of two new mono- and di-substituted phthalonitriles namely 4-((9 H -carbazol-3-yl)oxy)-5-chlorophthalonitrile and 4,5-bis((9 H -carbazol-3-yl)oxy)phthalonitrile, respectively. Cyclotetramerization of the new phthalonitriles in the presence of zinc(II) acetate resulted in related zinc(II) phthalocyanines. To study the effect of the position and number of substituents on the biological properties of the phthalocyanines, peripherally or non-peripherally tetra-substituted zinc(II) phthalocyanines bearing (9 H -carbazol-3-yl)oxy groups, as well as axially di-substituted silicon phthalocyanines containing the same groups, were prepared...
