Article Synopsis
  • - Klebsiella quasipneumoniae, often confused with K. pneumoniae, is a significant pathogen, and this study focuses on understanding its antibiotic resistance and virulence from a specific strain (B105) found in hospital wastewater.
  • - Using whole-genome sequencing, the researchers identified that strain B105 is resistant to several antibiotics but still susceptible to gentamicin, revealing key genes related to its virulence and resistance mechanisms.
  • - The study highlights the limitations of traditional methods in distinguishing between these two species and underscores the importance of genomic analysis in identifying K. quasipneumoniae, with implications for environmental health risks due to its antibiotic resistance profile.

Article Synopsis
  • SARS-CoV-2, the virus causing COVID-19, can transmit between humans and pets, raising concerns about its potential health risks.
  • * A study analyzed data and mutations of the virus from 2019 to 2023, identifying 47 mutations, with D614 being the most common among pets and humans.
  • * The findings indicate that variants of concern are spreading from infected owners to pets, emphasizing the need for increased global surveillance of the virus's evolution.*

Objectives: This study investigated the antidiabetic effects of the methanolic extract of (MEEA) stem bark on streptozotocin (STZ)-induced diabetic nephropathy (DN) in Wistar rats.

Methods: The enzyme (α-amylase) inhibitory activity of MEEA was measured using a standard procedure. Diabetic rats with fasting blood glucose above 250 mg/dL were considered diabetic and were divided into the following groups: control (distilled water-treated), diabetic-control, diabetic metformin (100 mg/kg), diabetes + MEEA (150 mg/kg), and diabetes + MEEA (300 mg/kg) via oral gavage once daily for 14 days.

The fertilizing effects of biodigestate produced from biogas plants on crop and soil productivity are very scarce. Hence, a field study was conducted in 2022 at the Teaching and Research Farm of Bowen University, Iwo, Osun State, Nigeria. The study evaluated the effects of biodigestate fertilizer, applied alone or in combination with urea, single superphosphate, or muriate of potash fertilizers at low (N, K, and P) and high (N, P, and K) rates on soil chemical properties, growth, and yield of maize ( (L.

Globally, legumes are vital constituents of diet and perform critical roles in maintaining well-being owing to the dense nutritional contents and functional properties of their seeds. While much emphasis has been placed on the major grain legumes over the years, the neglected and underutilized legumes (NULs) are gaining significant recognition as probable crops to alleviate malnutrition and give a boost to food security in Africa. Consumption of these underutilized legumes has been associated with several health-promoting benefits and can be utilized as functional foods due to their rich dietary fibers, vitamins, polyunsaturated fatty acids (PUFAs), proteins/essential amino acids, micro-nutrients, and bioactive compounds.

The effects of organic fertilizers, based on Tithonia diversifolia, and in-organic fertilizers, based on hydroponics fertilizer, were evaluated on the performance, leaves, and fruit mineral concentrations of tomato (Solanum lycopersicum) and cucumber (Cucumis sativus) plants grown under soilless medium in a screen house. The treatments comprised six levels of liquid organic fertilizer (5, 15, 25, 35, 45, 55 mL), in-organic fertilizer, and a control. Both organic and in-organic fertilizers increased the growth, yield, leaf nutrient concentration, and the mineral contents of tomato and cucumber fruits in comparison with the control.

The benefits derived from fermented foods and beverages have placed great value on their acceptability worldwide. Food fermentation technologies have been employed for thousands of years and are considered essential processes for the production and preservation of foods, with the critical roles played by the autochthonous fermenting food-grade microorganisms in ensuring food security and safety, increased shelf life, and enhanced livelihoods of many people in Africa, particularly the marginalized and vulnerable groups. Many indigenous fermented foods and beverages of Africa are of plant origin.

Article Synopsis
  • The study focused on the effectiveness of Velvet Tamarind-Pericarp, activated with HPO, for adsorbing caffeine from water.
  • Key parameters like initial caffeine concentration, pH levels, and residence time were tested, showing best performance at a pH of 6 and a residence time of 40 minutes.
  • The results indicated that this method is efficient and cost-effective for caffeine removal, with strong conformity to adsorption models and favorable thermodynamic properties.

Field experiments were carried out in 2018 and 2019 cropping seasons at Landmark University Teaching and Research farm, Omu-Aran Kwara state, Nigeria, to determine the effect of soil applied Zn-fertilizer, Tithonia diversifolia (Ti), Chromolaena odorata (Ch) and poultry manure (PM) on the performance, yield, minerals and vitamins composition of okra fruits. Treatments were combined and tested as follows:-Control (T), Control + 10 kg ha Zn (T), 5 t ha Ti + 5 t ha PM (T), 5 t ha Ch + 5 t ha PM (T), 5 t ha Ch + 5 t ha Ti (T), 10 t ha Ti + 0 kg ha Zn (T), 10 t ha Ti + 10 kg ha Zn (T), 10 t ha Ch + 0 kg ha Zn (T), 10 t ha Ch + 10 kg ha Zn (T), 10 t ha PM + 0 kg ha Zn (T), and 10 t ha PM + 10 kg ha Zn (T). The experiment was laid out in a randomized complete block design with four repetitions.

The study investigated bioenergy generation from anaerobic co-digestion of food wastes (FW), cow dung (CD) and piggery dung (PD). The physicochemical parameters of the substrates were determined before and after digestion following standard procedures after mechanical pretreatment. Throughout the study, pH remained slightly alkaline while temperature varied between 26 and 32 °C.
