Sphingolipids in Childhood Asthma and Obesity (SOAP Study): A Protocol of a Cross-Sectional Study.

Asthma and obesity are two of the most common chronic conditions in children and adolescents. There is increasing evidence that sphingolipid metabolism is altered in childhood asthma and is linked to airway hyperreactivity. Dysregulated sphingolipid metabolism is also reported in obesity.

Obesity-Associated Non-T2 Mechanisms in Obese Asthmatic Individuals.

Obesity and asthma are two common health issues that have shown increased prevalence in recent years and have become a significant socioeconomic burden worldwide. Obesity increases asthma incidence and severity. Obese asthmatic individuals often experience increased exacerbation rates, enhanced airway remodeling, and reduced response to standard corticosteroid therapy.

Role of Obesity in Inflammation and Remodeling of Asthmatic Airway.

Obesity is considered as an important risk factor for the onset of asthma and plays a key role in enhancing the disease's severity. Obese asthmatic individuals represent a distinct phenotype of asthma that is associated with additional symptoms, more severe exacerbation, decreased response to standard medication, and poor quality of life. Obesity impairs the function of the lung airway in asthmatic individuals, leading to increased inflammation and severe remodeling of the bronchus; however, the molecular events that trigger such changes are not completely understood.

The common type of AKI observed in patients with cirrhosis are prerenal AKI (PRA), hepatorenal syndrome (HRS) and acute tubular necrosis (ATN). Despite the growing knowledge and uniform definition for the diagnosis of AKI, there are several challenges including, early diagnosis and management.

Strategies to Improve Insulin Delivery through Oral Route: A Review.

Diabetes mellitus is found to be among the most suffered and lethal diseases for mankind. Diabetes mellitus type-1 is caused by the demolition of pancreatic islets responsible for the secretion of insulin. Insulin is the peptide hormone (anabolic) that regulates the metabolism of carbohydrates, fats, and proteins.

Protein arginine methyltransferase 5 (PRMT5) activates WNT/β-catenin signalling in breast cancer cells via epigenetic silencing of DKK1 and DKK3.

Protein arginine methyltransferase 5 (PRMT5) activity is dysregulated in many aggressive cancers and its enhanced levels are associated with increased tumour growth and survival. However, the role of PRMT5 in breast cancer remains underexplored. In this study, we show that PRMT5 is overexpressed in breast cancer cell lines, and that it promotes WNT/β-CATENIN proliferative signalling through epigenetic silencing of pathway antagonists, DKK1 and DKK3, leading to enhanced expression of c-MYC, CYCLIN D1 and SURVIVIN.

Evaluation of selected pharmaceuticals and personal care products in water matrix using ion trap mass spectrometry: A simple weighted calibration curve approach.

A novel analytical method is presented for 12 target pharmaceutical and personal care products (PPCPs), belonging to different classes like antibiotics, non-steroid anti-inflammatory drugs, parabens, UV-filters, plasticizer, and antibacterials. The method development comprises of solid-phase extraction (SPE) with lipophilic-hydrophilic material balanced Oasis HLB cartridge, followed by reverse-phase liquid chromatography interfaced to linear ion trap tandem mass spectrometry (LC-MS/MS) with electrospray ionization. Chromatographic separation was achieved with a gradient elution of 25 min run time using 5 mM ammonium acetate buffer with pH adjustment using acetic acid.

Protein arginine methyltransferase 5 (PRMT5) dysregulation in cancer.

Protein arginine methyltransferases (PRMTs) are known for their ability to catalyze methylation of specific arginine residues in a wide variety of cellular proteins, which are involved in a plethora of processes including signal transduction, transcription, and more recently DNA recombination. All members of the PRMT family can be grouped into three main classes depending on the type of methylation they catalyze. Type I PRMTs induce monomethylation and asymmetric dimethylation, while type II PRMTs catalyze monomethylation and symmetric dimethylation of specific arginine residues.

Mid borderline leprosy in type Bα Blaschko linear pattern: a rare phenomenon.

AEROSOL SIZE DISTRIBUTION IN URANIUM PROCESSING FACILITY FOR APPLICATION IN THE ASSESSMENT OF INTERNAL EXPOSURE.

In circumstances of inhalation exposure the radiotoxicity of radionuclide depends on the fractional deposition of inhaled activity, which is governed by the aerodynamic characteristics of the particles. Although International Commission on Radiological Protection (ICRP) provides default size distribution parameters for work place aerosols, inhaled aerosol characteristics may be different depending on the physical and chemical conditions of aerosol generation process. The present study is undertaken to determine the particle activity-size distribution during operation of various significant processes of uranium metal production facility of Bhabha Atomic Research Centre (BARC).

Cerebral Venous Thrombosis in Pregnancy-A Poignant Allegory of an Unusual Case.

Cerebral Venous Thrombosis (CVT), also known as cortical venous, cerebral sinus, cerebral venous sinus, or dural sinus thrombosis, is an infrequent grave condition affecting pregnant females, resulting from clot formation in one of the many outflow tracts of the brain. Although pregnancy-associated stroke or CVT is uncommon, the risk of stroke is greatly increased above the low baseline rate in young patients during late pregnancy and, even more so, during the puerperium. Haemorrhagic infarction can occur in the acute stage of CVT.

Combined Central and Peripheral Demyelination.
