Influence of drought stress on phosphorus dynamics and maize growth in tropical ecosystems.

Drought has a significant impact on ecosystem functions, especially on the biogeochemical cycling of phosphorus (P), which is a crucial nutrient for plant growth and productivity. Despite its importance, the effects of different drought scenarios on soil P cycling and availability remain poorly understood in previous studies. This study simulated drought conditions in tropical soils using maize as a test crop under varying field capacity (FC) levels (100%, 80%, 60%, 40%, and 20%) over a 60-day pot experiment.

Correlation analysis of global sagittal alignment of the spine in cases of low-grade degenerative lumbar spondylolisthesis.

Purpose: Disruptions in global sagittal spinal alignment can lead to changes in global sagittal spinal alignment, often manifesting as sagittal malalignment, where the trunk shifts forward. We proposed that these alignment changes are linked to degenerative lumbar spondylolisthesis (DS). The objective was to assess global spinal alignment in low-grade DS using sagittal vertical axis (SVA) classification.

Exploring the impact of Brownian motion on novel closed-form solutions of the extended Kairat-II equation.

This work considers a stochastic form of an extended version of the Kairat-II equation by adding Browning motion into the deterministic equation. Two analytical approaches are utilized to derive analytical solutions of the modified equation. The first method is the modified Tanh technique linked with the Riccati equation, which is implemented to extract some closed-form solutions in the form of tangent and cotangent functions.

Atrial Functional Tricuspid Regurgitation: A Comprehensive Review of Pathophysiology, Diagnosis, and Management Strategies.

Atrial fibrillation (AF), the most prevalent sustained cardiac arrhythmia, is intricately linked with atrial functional tricuspid regurgitation (AFTR), a condition distinguished from ventricular functional tricuspid regurgitation by its unique pathophysiological mechanisms and clinical implications. This review article delves into the multifaceted aspects of AFTR, exploring its epidemiology, pathophysiology, diagnostic evaluation, and management strategies. Further, we elucidate the mechanisms underlying AFTR, including tricuspid annular dilatation, right atrial enlargement, and dysfunction, which collectively contribute to the development of tricuspid regurgitation in the absence of significant pulmonary hypertension or left-sided heart disease.

Antibacterial activity of camel colostrum against pathogenic strain of F17-associated with calf diarrhea.

Background: Many protective proteins, including lactoferrin and heavy chain antibodies, are present in camel colostrum, giving it a distinctive composition. Beyond a broad spectrum of pathogens, these proteins demonstrate antibacterial properties.

Aim: The current research assessed the prophylactic properties of camel colostrum against F17.

Ultrasound-assisted extraction versus traditional Soxhlet apparatus for the obtention of polyphenols, carotenoids and tocopherols from Tagetes erecta L. flowers.

Background: Tagetes erecta L., commonly known as American marigold, serves as a food plant used for the extraction of carotenoids such as lutein, employed both as culinary ingredient in certain dishes and for its ornamental and medicinal applications. Two extraction techniques, Soxhlet and ultrasound-assisted extraction (UAE), were used on two cultivars (yellow and orange) of T.

Role of inflammatory markers in predicting spontaneous passage of ureteral stones less than 10 mm.

Introduction: In ureterolithiasis, the prediction of spontaneous passage poses a challenge for urologists. Moreover, there is controversy surrounding the preferred management approach, whether medical or surgical, as each approach has its disadvantages. Procalcitonin and other inflammatory markers were studied for predicting stone passage spontaneously, but their significance remains controversial.

Coinfection of some respiratory viruses in cattle: An abattoir study.

To investigate the existence of bovine viral diarrhoea virus (BVDV), parainfluenza virus 3 (PIV-3) and respiratory syncytial virus (RSV) as well as its coinfections, a total of 420 pneumonic lung tissue samples were collected from slaughterhouses in three different areas. Samples were examined for the three viruses using antigen detection enzyme-linked immunosorbent assay (ELISA) test, and positive results were further confirmed using fluorescent antibody test and polymerase chain reaction. Prevalences detected were 10.

Association of Liver Biomarkers With Jaundice in Patients With Gastrointestinal Complications: An Observational Retrospective Cohort Study.

Introduction: Jaundice is a state of disease in liver function often along with gastrointestinal (GI) complications primarily characterized by hyperbilirubinemia. Other tests regarding liver function are often used besides bilirubin as during any liver complications biomarkers such as alanine aminotransferase (ALT), serum glutamic pyruvic transaminase (SGPT), aspartate aminotransferase (AST), serum glutamic-oxaloacetic transaminase (SGOT), alkaline phosphatase (ALP), and many other biomarkers even total protein metabolism might get disrupted and get released in the blood. However, no comparison or association among those biomarkers was determined in a cohort.

Effect of Polyethylene Glycol and Humic Acid Coating on NPK Release From Controlled-Release Fertilizer.

Plants require essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), but their availability in soil is often inefficient due to evaporation, leaching, and binding. Controlled-release fertilizers (CRFs) provide a solution by regulating nutrient release over time. This study evaluates the effects of two coating materials, polyethylene glycol (PEG) and humic acid, on the release patterns of N, P, and K during an 18-week incubation using Inceptisol from Bogor, Indonesia.
