Maize plants can recover from fall armyworm damage under optimum crop production conditions in humid tropical agro-ecologies.

Farmers in Africa perceive the impact of fall armyworm (FAW) on maize to be significant, but field assessments have shown that yield losses are not significant enough to warrant pesticide interventions. This suggests that relationships between the crop stages, time, and duration of attack can affect the yield. Therefore, assessing the plant's recovery from damage using individual plants based on defoliation levels could guide whether and when pesticides should be applied.

New okra genotypes for the management of aphids (Hemiptera: Aphididae) in the diverse ecological landscapes of Central Africa.

Various aphid species, including Aphis gossypii Glover (Hemiptera: Aphididae), are considered important pests of okra and other vegetables. Previous studies under 1 environment in Cameroon, Central Africa, had found multiple okra genotypes with resistance to A. gossypii.

Impact of Spodoptera frugiperda (Lepidoptera: Noctuidae), on maize yield in humid tropical zones of Central Africa.

Fall armyworm, Spodoptera frugiperda Smith, became the most important maize pest in Africa in 2016, with management based on chemical pesticides. High yield losses across the continent were predicted based on farmers' perceptions, but existing agroecological differences were not considered. In the Democratic Republic of Congo, experiments were conducted to assess fall armyworm damage and yield losses in maize farms with and without treatment.

Reliability of Pheromone Trap Catches and Maize Plant Damage as Criteria for Timing Fall Armyworm Control Interventions in Humid Forest Agroecology of Central Africa.

Control of fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) since its invasion of Africa still depends on pesticides.

Natural Enemies of Fall Armyworm (Lepidoptera: Noctuidae) in Different Agro-Ecologies.

Fall armyworm (FAW) (J.E. Smith) and southern armyworm (SAW) (Stoll) have become major threats to crops in Africa since 2016.

Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) in Cameroon: Case study on its distribution, damage, pesticide use, genetic differentiation and host plants.

Maize farmers in sub-Saharan Africa recently experienced unusual damage in their farms, attributed to the fall armyworm (FAW) Spodoptera frugiperda (J. E. Smith).

Influence of mounting on the hysteresis of polymer fiber Bragg grating strain sensors.

Fiber Bragg grating sensors recorded in poly(methyl methacrylate) fiber often exhibit hysteresis in the response of Bragg wavelength to strain, particularly when exposed to high levels of strain. We show that, when such a fiber grating sensor is bonded directly to a substrate, the hysteresis is reduced by more than 12 times, compared to the case where the sensor is suspended freely between two supports.

Oral health status of 16-year-old school children in Malaysia.

The aim of the present study was to determine the oral health status of 16-year-old Malaysian school children. The prevalence of caries was 75.5%.

Childhood obesity: a simple equation with complex variables.

The prevalence of childhood obesity is rising rapidly, as are the associated medical complications, including type 2 diabetes, hypertension, and coronary heart disease. This has significant medical and socioeconomic implications. The definition of obesity in adults is based on body mass index (BMI), which has been correlated with morbidity and mortality.

A New High-performance Liquid Chromatographic Method for Fludarabine and Fludarabine Phosphate Compounded in Liposomes.

A simple and reproducible high-pressure liquid chromatography (HPLC) method was developed to measure simultaneously the concentrations of both fludarabine and liposome-compounded fludarabine in plasma. In this method, hypoxanthine 9-B-D arabinofuranoside was used as an internal standard. Fludarabine, fludarabine phosphate, and hypoxanthine 9-B-D arabinofuranoside were extracted from plasma and were separated by means of isocratic elution from a C18 reversed-phase column.

Efficacy and safety of oral granisetron versus i.v. granisetron in patients undergoing peripheral blood progenitor cell and bone marrow transplantation.

This randomized, controlled, double-blind pilot study assessed the efficacy and safety of oral versus i.v. granisetron, both in combination with non-5-HT3 antiemetics, in preventing emesis caused by high-dose chemotherapy.

The clinical pharmacology of topoisomerase I inhibitors.

The Chinese tree Camptotheca acuminata, or Xi Shu, brings us a unique class of chemotherapeutic agents known as the camptothecins. Because the parent compound exhibited excessive toxicity and poor aqueous solubility, synthetic and semisynthetic analogs were developed. These compounds contain a lactone ring that is necessary for activity and is easily hydrolyzed into the less active hydroxy carboxylic acid.
