Challenges and unique considerations of adolescents with chronic kidney disease.

Chronic kidney disease (CKD) is an increasingly prevalent disease that burdens patients of all ages significantly. While much data have been gathered on adult and paediatric populations, there is a lack of data on the effects of CKD on young adults and adolescents. The aim of this review was to look at the prevalence and comorbidities of this patient population, considering the rapid biological growth and development during this time frame.

Synthesis and Biological Evaluation of 5'--Fatty Acyl Ester Derivatives of 3'-Fluoro-2',3'-dideoxythymidine as Potential Anti-HIV Microbicides.

A number of 5′-O-fatty acyl derivatives of 3′-fluoro-2′,3′-dideoxythymidine (FLT, 1) were synthesized. These conjugates were evaluated for their potential as topical microbicides with anti-HIV activity against cell-free (X4 and R5), cell-associated, and multidrug-resistant viruses. Compared to FLT and 3′-azido-2′,3′-dideoxythymidine (AZT), 5′-O-(12-azidododecanoyl) (5), 5′-O-myristoyl (6), and 5′-O-(12-thioethyldodecanoyl) (8) derivatives of FLT were found to be more active against both cell-free viruses (lymphocytotropic and monocytotropic strains) with EC50 values of 0.

Application of Quantitative NMR (qHNMR) towards Establishment of Pharmaceutical Reference Standard; A Case of a Ticagrelor Process Impurity.

Quantitative proton NMR (qHNMR) methodology was employed for the stoichiometric (free base and the corresponding counterion) assessment of a ticagrelor process impurity, also referred to in the United States Pharmacopeia (USP), Pharmacopeial Forum as Ticagrelor Related Compound A (RC A), [(1R,2S)-2-(3,4-difluorophenyl)cyclopropan-1-amine (R)-mandelate], also called as Tica amine mandelate, a critical impurity that, when present during manufacturing, has a limit of not more than 0.0008%. The Tica amine is also a listed impurity E in the Ticagrelor monograph, in European Pharmacopeia.

The qNMR Summit 5.0: Proceedings and Status of qNMR Technology.

The goal of the qNMR Summit is to take stock of the status quo and the recent developments in qNMR research and applications in a timely and accurate manner. It provides a platform for both advanced and novice qNMR practitioners to receive a well-rounded update and discuss potential qNMR-related applications and collaborations. For over a decade, scientists from academia, industry, nonprofit institutions, and governmental bodies have focused on the standardization of qNMR methodology, as well as its metrological and pharmacopeial utility.

Facilitated structure verification of the biopharmaceutical peptide exenatide by 2D heteronuclear NMR maps.

Exenatide is a peptide based anti-diabetic prescription medication. Until now, the literature has lacked a comprehensive atom-specific molecular characterization for this complex large peptide by NMR spectroscopy that can be effortlessly and rapidly utilized for biopharmaceutical structural veracity. Peptide structure verification by NMR is challenging and cumbersome when reliant on traditional proton-based methodology (through-bond and through-space proton connectivity) alone due to increasing complexity, low signal dispersion, and overlap.

From subconscious to conscious to artificial intelligence: A focus on electronic health records.

A paradigm shift in human evolution, from our predecessors, the 'hunter-gatherers' to the 'era of digital revolution', has made certain human skills more and more machine driven. This digital revolution has made possible a constant connectivity, wearable technologies, customized platforms, enormous data storage and cloud computing at high speeds, smart phones and apps, internet of things, artificial intelligence, telemedicine, etc. These have made real-time monitoring and interventions possible in healthcare.

Sixty years of Neurosurgery at Andhra Medical College and King George Hospital, Visakhapatnam: The (hi) story of the department.

The trials and trepidations of an emerging department, uncertainties of its survival midway through its course, the innovative ideas that initiated its development, a regimental discipline, addition of newer technological advances with changing times, and its blossoming as the one of the best departments in the region, mark the origin and development of the Department of Neurosurgery at Andhra Medical College (AMC) and King George Hospital (KGH) Visakhapatnam. AMC and KGH are getting ready to celebrate their centenary in 2023. This history of the department is derived from the knowledge of the immense effort and academic discipline that was required to bring it to its current stature.

Emtricitabine prodrugs with improved anti-HIV activity and cellular uptake.

Three fatty acyl conjugates of (-)-2',3'-dideoxy-5-fluoro-3'-thiacytidine (FTC, emtricitabine) were synthesized and evaluated against HIV-1 cell-free and cell-associated virus and compared with the corresponding parent nucleoside and physical mixtures of FTC and fatty acids. Among all the compounds, the myristoylated conjugate of FTC (5, EC(50) = 0.07-3.

Dissolution of sulphur particles by Thiobacillus ferrooxidans: substrate for unattached cells.

The growth of Thiobacillus ferrooxidans on sulphur is known to proceed through the attachment of cells to the sulphur particles. Experiments, However, show that the cells in the liquid phase, which are not attached to the sulphur particles, also grow. It has been shown through the use of a two-compartment membrane reactor that this increase is partially due to the release of ions, corresponding to partially oxidized of sulphur, into the solution by the attached cells.
