Background: Diabetes mellitus (DM) is a chronic metabolic disease characterized by elevated blood glucose levels. Over time, it can lead to serious complications in the eyes, heart, blood vessels, kidneys, and nerves, being the leading cause of blindness among working-age patients.
Aim And Methods: This descriptive observational cross-sectional study aims to evaluate the factors affecting the awareness of the general adult diabetic population about their chronic disease and its complications.
Multiple myeloma (MM) is typically characterized by the neoplastic proliferation of plasma cells producing a monoclonal immunoglobulin. Pleural effusion in MM is uncommon and usually caused by heart failure, pulmonary embolus, and nephrotic syndrome [. 1978;138(5):727-30; .

Many studies have shown it is strongly associated with increased social and psychological problems such as depression and anxiety which are considered as common psychiatric disorders that occur in patients with chronic kidney disease. We investigated the prevalence of depression, anxiety and perception of quality of life in a sample of chronic kidney disease patients at the Jordan University Hospital.

Eosinophilic esophagitis (EE) is the most common and best-understood disease in this category. Activated mast cells (MCs) have a role to play in the tissue damage in EE.

Results: During the follow up period, three cases of thyroid cancer were identified. The prevalence of thyroid cancer was 1.
Valosine-containing protein (VCP), also known as p97 or cdc48 in yeast, is a highly abundant protein belonging to the AAA ATPase family involved in a number of essential cellular functions, including ubiquitin-proteasome mediated protein degradation, Golgi reassembly, transcription activation, and cell cycle control. Altered expression of VCP has been detected in many cancer types sometimes associated with poor prognosis. Furthermore, VCP mutations are causative of some neurodegenerative disorders.

After high-throughput screening, we developed compounds that inhibit VCP via different mechanisms, including covalent modification of an active site cysteine and a new allosteric mechanism. Using photoaffinity labeling, structural analysis and mutagenesis, we mapped the binding site of allosteric inhibitors to a region spanning the D1 and D2 domains of adjacent protomers encompassing elements important for nucleotide-state sensing and ATP hydrolysis.

VCP is an ubiquitously expressed, highly abundant protein and has been found overexpressed in many tumor types, sometimes associated with poor prognosis. In this respect, VCP has recently received a great deal of attention as a potential new target for cancer therapy.

Goal: To assess the need for screening programs to detect sexually transmitted infections.
Study Design: This is a cross-sectional study wherein consecutive symptomatic and asymptomatic women presenting to gynecology and family planning clinics from different areas in Jordan were tested for reproductive tract infections caused by Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, and Trichomonas vaginalis.
PSGL-1, a specific ligand for P-, E- and L-selectin, was isolated from in vivo [3H]-glucosamine labeled HL-60 cells by a combination of wheat germ agglutinin-agarose and P- or E-selectin-agarose chromatography. N-linked oligosaccharides were released from the purified, denatured ligand molecule by peptide: N-glycosidase F treatment and, following separation by Sephacryl S-200 chromatography, partially characterized using lectin, ion-exchange and size-exclusion chromatography in combination with glycosidase digestions. The data obtained suggest that the N-glycans on PSGL-1 are predominantly core-fucosylated, multiantennary complex type structures with extended, poly-N-acetyllactosamine containing outer chains.

The O-linked oligosaccharides on the ligand were released by mild alkaline sodium borohydride treatment and analyzed by a combination of ion-exchange, size exclusion, lectin, and paper chromatography, together with specific exoglycosidase treatments and chemical modifications. Approximately 91% of the radioactivity released from PSGL-1 was recovered in five O-linked glycans: GalNAc (approximately 4% of the total structures), Galp, 3GalNAc (36%), and Galbeta, 3GalNAc substituted with one (45%), two (6%), or three (3%) N-acetyllactosamine repeat units.

We have described a panel of monoclonal antibodies which recognize a sialoglycoprotein from human neutrophils and HL-60 promyelocytic cells and inhibit adhesion of these cells to P-selectin. In this study, we show that the E-selectin receptor-globulin (E-selectin Rg) affinity chromatography can isolate specifically only one glycoprotein from [3H]glucosamine-labeled HL-60 cells in a Ca(2+)-dependent manner.

In this study, purification of a heparan sulfate-degrading enzyme from human platelets led to the discovery that the enzymatic activity residues in at least two members of the platelet basic protein (PBP) family known as connective tissue activating peptide-III (CTAP-III) and neutrophil activating peptide-2. PBP and its N-truncated derivatives, CTAP-III and neutrophil activating peptide-2, are CXC chemokines, a group of molecules involved in inflammation and wound healing.

P-selectin (CD62P), a Ca(2+)-dependent lectin expressed on activated platelets and endothelial cells, functions as a receptor for myeloid and monocytoid cells. Previous reports have described a homodimeric sialoglycoprotein from human leukocytes and HL-60 cells specifically recognized by P-selectin. We describe here a panel of monoclonal antibodies prepared against high molecular weight fractions of HL-60 cell membranes.

The three known selectins, L-selectin (leukocyte adhesion molecule-1 [LECAM-1]), E-selectin (endothelial-leukocyte adhesion molecule-1 [ELAM-1]), and P-selectin (GMP-140) share structural features that include a calcium-dependent lectin domain. The sialyl Lewis(x) carbohydrate epitope has been reported as a ligand for both E- and P-selectins.

Several receptors have been implicated in this adhesion and migration process, including the selectins, a family of carbohydrate-binding proteins. The ligand for one of these proteins, E-selectin (LECAM-2, ELAM-1) has been described by several groups to contain a polylactosamine structure bearing a terminal sialic acid residue and at least one fucose residue.

However, when exposed to thallium acetate (a cytotoxic heavy metal), macrophages supported growth of mycoplasmas almost as well as did untreated fibroblasts. This suggests an active antimycoplasmal process operative in untreated macrophages.
