Summary
Pollen in Lagos, Nigeria, significantly correlates with allergy cases like wheezing cough. Dominant airborne pollens include Alchornea cordifolia, Cyperaceae, and Poaceae, impacting individuals aged 15-49.
Area of Science:
- Environmental Science
- Allergology
- Aerobiology
Background:
- Research on airborne pollen and allergy (pollinosis) in Africa is limited.
- Understanding local pollen types is crucial for managing allergic diseases.
Purpose of the Study:
- To investigate the relationship between airborne pollen and pollinosis in Gbagada, Lagos State, Nigeria.
- To identify dominant pollen types and their correlation with allergy symptoms.
Main Methods:
- Monthly air sampling for pollen grains from January 2013 to December 2014.
- Correlation analysis of pollen data with allergy cases (wheezing cough, rhinitis, allergic conjunctivitis) from Gbagada General Hospital.
- Identification of dominant pollen species: Alchornea cordifolia, Amaranthaceae, Casuarina equisetifolia, Cyperaceae, and Poaceae.
Main Results:
- Wheezing cough was the most frequent allergy, with highest records in 2014 (1409 cases).
- The 15-49 age group showed the highest prevalence of pollinosis.
- Peak pollen seasons (Oct-Dec 2013, Oct-Mar 2014) correlated with increased allergy symptoms, particularly wheezing cough.
Conclusions:
- Total airborne pollen count significantly correlates with wheezing cough cases.
- Specific pollens like Cyperaceae and Poaceae showed significant positive correlation with wheezing cough in 2014.
- Further aerobiological studies across Nigeria are recommended to establish comprehensive pollinosis epidemiology.

02:26Comparing Copy Number Variations and SNPs
18.8K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.

6.0K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

01:20Comparing the Survival Analysis of Two or More Groups
605
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

02:16Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes
16.3K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

02:34Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility
51.6K
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...
