Genomic miscellany and allelic frequencies of Plasmodium falciparum msp-1, msp-2 and glurp in parasite isolates.

INTRODUCTION: The genomic miscellany of malaria parasites can help inform the intensity of malaria transmission and identify potential deficiencies in malaria control programs. This study was aimed at investigating the genomic miscellany, allele frequencies, and MOI of P. falciparum infection. METHODS: A total of 85 P. falciparum confirmed isolates out of 100 were included in this study that were collected from P. falciparum patients aged 4 months to 60 years in nine districts of Khyber Pakhtunkhwa Province. Parasite DNA was extracted from 200µL whole blood samples using the Qiagen DNA extraction kit following the manufacturer's instructions. The polymorphic regions of msp-1, msp-2 and glurp loci were genotyped using nested PCR followed by gel electrophoresis for amplified fragments identification and subsequent data analysis. RESULTS: Out of 85 P. falciparum infections detected, 30 were msp-1 and 32 were msp-2 alleles specific. Successful amplification occurred in 88.23% (75/85) isolates for msp-1, 78.9% (67/85) for msp-2 and 70% (60/85) for glurp gene. In msp-1, the K1 allelic family was predominantly prevalent as 66.66% (50/75), followed by RO33 and MAD20. The frequency of samples with single infection having only K1, MAD20 and RO33 were 21.34% (16/75), 8% (6/75), and 10.67% (8/75), respectively. In msp-2, both the FC27 and 3D7 allelic families revealed almost the same frequencies as 70.14% (47/67) and 67.16% (45/67), respectively. Nine glurp RII region alleles were identified in 60 isolates. The overall mean multiplicity of infection for msp genes was 1.6 with 1.8 for msp-1 and 1.4 for msp-2, while for glurp the MOI was 1.03. There was no significant association between multiplicity of infection and age groups (Spearman's rank coefficient = 0.050; P = 0.6) while MOI and parasite density correlated for only msp-2 allelic marker. CONCLUSIONS: The study showed high genetic diversity and allelic frequency with multiple clones of msp-1, msp-2 and glurp in P. falciparum isolates in Khyber Pakhtunkhwa, Pakistan. In the present study the genotype data may provide valuable information essential for monitoring the impact of malaria eradication efforts in this region.

Effect of temperature and humidity on coronavirus infection in Pakistan.

Ongoing Coronavirus epidemic (COVID-19) identified first in Wuhan, China posed huge impact on public health and economy around the globe. Both cough and sneeze based droplets or aerosols encapsulated COVID-19 particles are responsible for airborne transmission of this virus and caused an unexpected escalation and high mortality worldwide. Current study intends to investigate the correlation of COVID-19 epidemic with meteorological parameters, particularly temperature and humidity. A data set of Epidemiological data of COVID-19 for highly infected provinces of Pakistan was collected from the official website of (https://www.covid.gov.pk/) and weather data was collected from (https://www.timeanddate.com/) during the time period of 1st March to 30th September 2020. The GrapPad prism 5 Software was used to calculate the mean and standard error of mean (SEM). In the current study the incident of daily covid cases is recorded higher in the month of June while the less number of case were reported in the month of May as compared to the other months (April, May, June, July, September and August) in the four province of Pakistan. We also find out that the incident of Covid19 were high at higher temperature (like the average temperature in the month of June 37 °C) while less cases were reported in May the average temperature was 29.5 °C. Furthermore the incident of covid cases were less reported at low humidity while more intendant with high humidity. Pearson's (r) determine the strength of the relationship between the variables. Pearson's correlation coefficient test employed for data analysis revealed that temperature average (TA) and average humidity is not a significant correlated with COVID-19 pandemic. The results obtained from the current analysis for selected parameters indirect correlation of COVID-19 transmission with temperature variation, and humidity. In the present study association of parameters is not correlated with COVID-19 pandemic, suggested need of more strict actions and control measures for highly populated cities. These findings will be helpful for health regulatory authorities and policy makers to take specific measures to combat COVID-19 epidemic in Pakistan.

Morphological characteristics of native chicken of village Chhajjian, Haripur Pakistan.

The present study was conducted to describe the variations in morphological characteristics of different selected populations of indigenous chickens. Five populations of chickens in different (localities) of Chhajjian, KP, Pakistan, were studied based on qualitative traits recorded for a total of 100 chickens. Each of the study populations contains multiple variants of plumage colors and other physical features. The average flock size was observed to be 38. Predominant plumage color was grayish and other mixtures along with different percentages in different localities. Pea comb was the dominant comb type in all localities. Most of the chickens were yellow skinned. Males in all populations were heavier and taller than the females. This recorded variation in morphological traits will help in the conservation of these chickens.

The complete mitochondrial genome of blue pansy, Junonia orithya (Lepidoptera: Nymphalidae: Nymphalinae) from Pakistan.

Junonia orithya's complete mitochondrial genome (mitogenome) is determined to be 14,214 bp in length, including 37 typical mitochondrial genes and an AT-rich region. Its gene order and orientation are identical to those of other butterfly species. All PCGs are initiated by typical ATN codons, except for cox1 gene which is started by CGA codon. Nine genes use complete termination codon (TAA), whereas the COX1, COX2, NADH1 and NAH4 genes end with single T. Except for trnS1(AGN), all tRNA genes display typical secondary cloverleaf structures as those of other insects. The 331 bp long AT-rich region contains several features common to the other lepidopterans, such as the ATAGA motif followed by a 18 bp poly-T stretch, two microsatellite-like (TA) 9 elements, a 5 bp poly-A stretch immediately upstream of trNAM gene from Pakistan.

Cognitive and behavioral aspects affecting early referral of acute stroke patients to hospital.

Successful management of acute ischemic stroke is dependent on early referral for thrombolysis. We explored the key motivational factors affecting stroke sufferers and bystanders and their cognitive and behavioral responses, especially those that would affect prompt management of stroke. This study comprised a structured interview survey of patients and bystanders admitted to a stroke unit in an area where thrombolysis for acute stroke had not yet been introduced. Outcome measures (eg, knowledge of stroke, health beliefs, self-efficacy, and self-care responses) were recorded. Only 41% of the patients correctly assessed their symptoms to be stroke; 44% perceived their symptoms to be mild; and 59% would wait to see whether their symptoms would improve spontaneously. About 61% of the patients and 80% of the bystanders worried about troubling other people with their problem. The bystander was a relative in 68% of cases. Of the bystanders, 65% correctly assessed the symptoms as stroke; only 42% perceived the patient's symptoms as severe. About 25% of the bystanders took a passive approach and would wait and see whether symptoms improved spontaneously; 93% did not find it difficult to ask for assistance. To promote early referral to a hospital, educational strategies must address the public's knowledge and information base and seek to address the cognitive and behavioral processes involved so as to overcome barriers to action. Effective treatment for stroke must be emphasized.

Nest Architectural Patterns by Three Wasp Species (Vespa velutina, Polistes flavus and Sceliphron formosum) with Reference to Their Behavior.

In the present study, the nest architectural patterns, elemental analysis and their behavior were carried out in three wasp species: Vespa velutina (Lepeletier), Polistes flavus (Cresson) and Sceliphron formosum (Smith) from the different localities of the Mansehra, Pakistan. The V. velutina nest was completely closed except for one opening for entry or exit with 1-10 layers of hexagonal cells inside the nest. The nests of P. flavus were found among bunches of leaves of trees with 1-5 layers and hexagonal cells same as in V. velutina. Nests of the S. formosum were pitcher-shaped, found in muddy places, and consisted of 1-10 cells. Social behavior of wasps showed strong foraging, defensive behaviors, pseudo-attack, subsequent erratic flight, wing buzzing, mandibular pecking, abdominal pumping and abdominal twisting with highly developed parental care. It was concluded that the behaviors of these 3 wasp species was highly developed as compared with other insects.
