January 2025

Fenamates are the most crucial non-steroidal anti-inflammatory drugs (NSAIDs) used to treat pain-related diseases. The clinically prescribed drugs of the fenamate group include mefenamic acid, tolfenamic acid, meclofenamic acid, flufenamic acid, and niflumic acid. Due to their widespread use, all these drugs are considered as the most common water and sewerage pollutants.

This chapter presents an overall account of cyclodextrins (CDs) with a brief description of the history, classification, and properties of these macromolecules. CDs act as complexing agents for drugs to form CD-drug inclusion complexes by various techniques. These complexes lead to the modification of the physicochemical properties of drugs to make them more soluble, chemically, and photochemically stable, and less toxic.

Article Synopsis
  • A reliable RP-HPLC method with UV detection was developed for the accurate measurement of Voriconazole in pure and gel formulations, using a 50:50 acetonitrile-water mobile phase and a flow rate of 1.0 ml/min.
  • The method demonstrated excellent linearity (correlation coefficient = 0.9999) and precision, with a percentage relative standard deviation (RSD) of less than 2.0.
  • Robustness was evaluated using variables like flow rate and pH; while flow rate significantly affected drug concentration, the method remained straightforward and suitable for daily quality control with a retention time of under 4 minutes.

Capillary zone electrophoresis-immunosubtraction (CZE-IS) is an essential laboratory test in diagnosing plasma cell neoplasms. However, the current interpretation of the test results is subjective. To evaluate CZE-IS in a more precise manner, this study proposed five key indexes, namely sharpness index, light chain index, immunoglobulin G index, immunoglobulin A index, and immunoglobulin M index.

Article Synopsis
  • Photodegradation of drug substances can produce both known and unknown products that interfere with analytical results due to absorption at certain wavelengths.
  • The study focuses on improving the accuracy of measurements for methylcobalamin (MC) and hydroxocobalamin by applying linear and non-linear methods to correct for irrelevant absorbances during photolytic degradation involving ascorbic acid (AH).
  • Methylcobalamin shows first-order degradation kinetics, with the degradation rate being pH-dependent; it peaks at pH 5.0 when in the presence of ascorbic acid, whereas degradation slows down in more alkaline conditions.

Human activities and climate change have resulted in frequent and intense weather fluctuations, leading to diverse abiotic stresses on crops which hampers greatly their metabolic activities. Heat stress, a prevalent abiotic factor, significantly influences cotton plant biological activities resulting in reducing yield and production. We must deepen our understanding of how plants respond to heat stress across various dimensions, encompassing genes, RNAs, proteins, metabolites for effective cotton breeding.

Software engineers post their opinions about various topics on social media that can be collectively mined using Sentiment Analysis. Analyzing this opinion is useful because it can provide insight into developers' feedback about various tools and topics. General-purpose sentiment analysis tools do not work well in the software domain because most of these tools are trained on movies and review datasets.

Terminal ballistics continues to struggle with bullet trajectory reconstruction and interpretation. This is a case of a young man presented with a very unusual trajectory of a bullet from the left shoulder to the brain parenchyma. The single wound and altered mentation prompted a CT head and neck scan, which revealed a retained bullet in the brain parenchyma, traversing from the left shoulder, across the neck and into the brain without causing significant damage to vital organs.

The biotechnological process called solid-state fermentation (SSF) was applied for hyper production of protease by using a fungal strain called . From screening of 9 different local substrates (peanut shell, wheat bran, guava leaves, sugar cane bagasse, rice polish, wheat straw, corn straw, reed grass, and rice straw), peanut shells serve as the best substrates for protease production under optimized cultured conditions. The varying physiochemical parameters such as pH (2-9.

A novel luminescence-based analytical methodology was established employing a europium(III) complex with 3-allyl-2-hydroxybenzohydrazide (HAZ) as the coordinating ligand for the quantification of gemifloxacin mesylate (GMF) in pharmaceutical preparations and human plasma samples spiked with the compound. The stoichiometry of the europium complex with HAZ was determined the Job plot and exhibited a metal-to-ligand ratio of 1 : 2. The analytical procedure relies on a rapid and significant enhancement of luminescence by the Eu(AZ) complex when it interacts with gemifloxacin mesylate, which allowed for the rapid detection of 96 samples within approximately 2 minutes.

Temporomandibular joint (TMJ) surgery accounts for a significant number of patient episodes in oral and maxillofacial surgery, and treatment effectiveness is commonly assessed using measures of pain and mouth opening. Patient-reported outcome measures (PROMs) enable assessment of the patient's perspective and perception of the diseases and treatment outcomes. The purpose of this review was to assess the use of PROMs in TMJ surgery.

This study aimed to investigate the impact of individual drought, heat, and combined drought and heat stress on twelve cotton genotypes, including eight tolerant and four susceptible genotypes. A field experiment was carried out by employing a randomized complete block split-plot design, with treatments (control, drought, heat, drought + heat), and cotton genotypes assigned to the main plots and sub-plots respectively. The results showed that the combined stress had a more severe impact on the yield and fiber quality of cotton genotypes compared to individual stresses.

Background: Germline alterations of the CDH1 (E-cadherin) tumor suppressor gene have been reported in several epithelial malignancies like hereditary diffuse gastric cancer and lobular breast cancer. E-cadherin plays a central role in proliferation, maintenance of cell-to-cell adhesion, polarity, and epithelial-mesenchymal transition of tissue cells. It is necessary to analyze the impact of the CDH1 germline sequence variants on protein and predict its clinical significance in breast cancer (BC) progression.
