Abstract
Fast radio bursts (FRBs) are flashes of unknown physical origin1. The majority of FRBs have been seen only once, although some are known to generate multiple flashes2,3. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission4,5. Recently, the discovery6 of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths6. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system7. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts.

Abstract
Background
Around 5.29% of the world population is suffering from ADHD, and 60 million people are suffering from CVS, with an increasing rate of prevalence of these disorders. This study aimed to determine the prevalence rate of ADHD and CVS symptoms among the Bangladeshi population.
Results
To assess the aim of the study, a cross-sectional survey was conducted online through stratified sampling, and 197 responses were collected from the participants. Our survey method follows these criteria where the ARSV1.1 standard questionnaire was followed for the ADHD questionnaire, and a self-administered questionnaire was established based on the symptoms of CVS. The male age ranges from 18–24 have the highest value of ADHD (34%) coincided with > 6 h digital device usage (51%), and the Stroop effect is significantly correlated with the ADHD score (0.498, p < 0.01). The Stroop effect value is also higher among the males aged 18–24, digital device users for > 6 h (48%).
Conclusions
With the advent of science, it is impossible to avoid digital devices as necessary. Notwithstanding, safe and appropriate use of digital media is a must for healthy living.

Abstract
A study was conducted in Dhubri and Biswanath Chariali Municipality areas to assess the adoption of hygienic and sanitation practices being followed by poultry butchers. A total of 60 poultry butchers were selected randomly, 30 from each Municipality area so that the final sample consisted of 60 poultry butchers. Data were collected using a pre-tested structured interview schedule by personal interviews. The schedule was designed to collect information on the socioeconomic profile of the butchers, personal and meat shop hygiene, maintenance of meat shop and its equipment. The data revealed that all the poultry butchers were male among which (75%) of them had an education level only up to eight standard. The overall mean age of the poultry butchers was found to be 39.95±8.64 years of which majority (75%) of them belong to middle age group. The present study indicated that none of the poultry butchers underwent any formal training for hygienic meat handling. It was also pointed out that most (85%) of the butcheries were located at market area, while only a few (15%) were found in the residential area. Only 18.33 per cent of the poultry butchers wore clean clothes while 81.67 per cent of them did not adopt this practice during working. Majority (88.33%) of them did not wash their hands after smoking/ chewing tobacco.It was also revealed that majority (88.33%) of the butchers did not clean knives before and after cutting of meat. Majority of the butchers agreed that cleanliness of equipment (71.67%), the meat shop and its surrounding (68.33%) and personal hygiene (68.33%) were some of the important factors that were essential to ensure wholesome meat production. From the above study, it may be concluded that appropriate interventional measures by the concerned agencies such as awareness trainings for poultry butchers on crucial areas of food safety, hygienic practices relating to meat handling and personal safety are imperative. The results of the study also shed light on the need for measures to improve the infrastructural facilities in poultry meat butcheries and for appropriate interventions to strengthen the food quality control system by the government regulatory authorities.

Abstract
Although huge improvement in neonatal mortality reduction in last two decades in Bangladesh but it is still very high compare with many other countries. High neonatal mortality also significantly contribute deaths among the under five children. Neonatal mortality reflects a nation's socio-economic status, efficiency and effectiveness of health care services. This was cross sectional study. The objective of this study was to analyse the diseases pattern and outcome of the neonates admitted in the newly established SCANU (Special care neonatal unit) of 250 bedded General Hospital of Tangail district, Bangladesh. Study period was one year from January 2017 to December 2017. Information from medical records of the SCANU was analysed. During the study period 1,379 neonates were admitted in the SCANU. The ratio between male and female was 1.5:1, 61% of the neonates admitted at first day of life. The reasons for admissions in SCANU were 31% of preterm and low birth weight, 23%birth asphyxia, 13% neonatal sepsis, 9% transient tachypnea of newborn, 5% congenital anomalies and 4% neonatal jaundice. Out of all neonates survival rate was 56% (779), while 25% (349) ended with fatality, 9% (122) were referred to tertiary level hospital and 10% (129) were left the hospital against medical advice. Among the fatal cases 63% died in first 24 hours and 88% in first week of life. Data shows that 47% deaths were due to preterm and low birth weight with its complication, other significant causes were birth asphyxia (30%), septicemia (16%) and congenital anomalies were (6%). Preterm and low birth weight, neonatal sepsis, birth asphyxia, transient tachypnea of newborn; congenital anomalies were the main reasons for admission in SCANU. Prematurity and its complication, birth asphyxia and neonatal sepsis as the major contributors to the neonatal mortality. The study findings will help researchers and policy makers to initiate further research and interventions to reduce fatality among the neonates in the SCANU.

Abstract
A life threatening rare condition called catastrophic antiphospholipid syndrome leading to multiple organ failure is characterized by vascular thrombosis in the presence of anti-phospholipid antibody which often appear as a medical emergency. Antiphospholipid antibody syndrome whether primary or secondary cause thromboembolic manifestation resulting recurrent fetal loss, but catastrophic antiphospholipid antibody syndrome may not present in such a way, rather multi-system involvement occurs within a short period of time. We would like to present a case of 50 years old female who is hypertensive, non-diabetic, a known case of hypothyroidism for two years, who was admitted to our hospital after developing fever for 7 days and black discoloration of lateral three fingers of left hand for short period of time. The patient had no medical problems and had been in her usual state of health until 7 days before admission. Patient is anaemic and found to have severe renal failure. She was found high titer antiphospholipid antibody both IgM and IgG positive and anti-cardiolipin antibody positive. Her routine investigations revealed very high neutrophilic leukocytosis, high acute phase reactant, urinary findings revealed no active sediment; we thought that our patient might have sepsis that may trigger catastrophic antiphospholipid syndrome. Multi-disciplinary consultation gave us valuable opinion. Considering her septicemia, she was given broad spectrum antibiotic. Anticoagulation was given with unfractionated heparin followed by warfarin and as an immunosuppressive protocol methylprednisolone followed by prednisolone along with pulse cyclophosphamide was given. Treatment option with plasma pheresis and monoclonal antibody was not attempted, but she was given several session of hemodialysis, within a few days her biochemical parameters improved. Severe renal failure in this patient may be explained by septicemia or thrombotic micro-angiopathy that was reversed with anti-coagulation or proper antibiotic. Amputation of three digit of left hand was done by orthopedic surgeon but unfortunately two weeks after admission the patient expired due to sudden stroke.

Abstract
Artificial incubation is fundamental in ex situ avian conservation interventions for an increasing range of threatened species, but incubation parameters can differ between species. Both egg-turning angle and frequency are critical for successful embryonic development, but measuring these parameters in wild birds has historically been difficult. Using data-loggers inside artificial eggs that accurately record parental egg attendance behaviours, we quantified turning angles and rates throughout the incubation of 6 nesting wild Asian houbaras Chlamydotis macqueenii, a species bred in captivity in response to human over-exploitation. Wild females turned their eggs 0.6 times h-1 with a mean angle of 40.9° turn-1. Mimicking the patterns of wild birds (‘wild’ treatment), we applied a mean angular change of 40-50° turn once h-1 to artificially incubated eggs and compared this to eggs treated with an existing protocol (‘control’) of 120-130° per turn. Mean hatchability for the wild treatment (78.8%, n = 766) was similar to the control (76.6%, n = 1196). The wild treatment (n = 591) produced significantly heavier hatchlings (2.7%) than the control treatment (n = 893). However, chick growth rates (g d-1 and daily % mass change) and survival to Day 10 were not different between groups. The wild treatment demonstrates that turning angles affect embryo development and, perhaps, hatchability. Investigating natural incubation behaviours using egg-loggers and applying these patterns to artificial incubation appears efficacious to achieve optimal incubation protocols and reduce the need for ex situ trial and error refinement in conservation interventions of captive-bred threatened bird species.

Abstract
Abstract
Background
Despite ample evidence of continued preoperative aspirin to improve outcomes in coronary artery bypass surgery, practice for routine continued preoperative aspirin use is still inconsistent due to concern for increased postoperative bleeding. The purpose of this study was to investigate preoperative aspirin use and its effect on postoperative bleeding after off-pump coronary artery bypass grafting (OPCABG).
Method
This cohort study involved patients (n = 74) who underwent OPCABG at a single center between August 2017 to January 2018. After considering the inclusion and exclusion criteria, they were divided into two groups: one (n = 37) received tablet Aspirin 75mg till the day of surgery and for the other group (n = 37) aspirin was stopped 5 days before surgery. Postoperative bleeding was recorded in both groups. After considering preoperative, intraoperative, and postoperative variables statistical analysis was done.
Results
There was no significant difference between the two groups concerning preoperative and peroperative variables. No significant difference was also observed between the two groups in chest tube drainage at 1sthour, 2ndhour, 3rdhour, 24thhour, next 24 hours (at 48th hour), and next 24 hours (at 72nd hour) (p = 0.845, 0.126, 0.568, 0.478, 0.342 and 0.717 respectively). No significant difference was seen in the transfusion requirement of blood and fresh frozen plasma (FFP).
Conclusions
Continuation of preoperative aspirin till the day of surgery is not associated with an increase in chest tube drainage, re-operation for bleeding complications, or transfusion of blood and FFP.

Abstract
Polyorchidism is a rare congenital anomaly reported about 200 cases in the world text. A number of theories have been planned concerning the making of polyorchidism, but the real explanation is still not acknowledged. Here we are going to present a case study of polyorchidism. A 70 years old gentleman complained with left supernumerary testes in the left hemiscrotum. His left hemiscrotum was painless with mass. Polyorchidism without malignancy or any other concomitant features were revealed by both ultrasound and MRI examinations. In most cases the ultrasonograph alone is diagnostic. In complicated cases of polyorchidism MRI may provide additional information.

Abstract
The effects of two processing methods (boiling and roasting) on physicochemical qualities
of dark red kidney bean (Phaseolus vulgaris) were investigated. Changes in total
polyphenol content (TPC) and antioxidant activity due to processing were also analyzed
by using Folin–Ciocaltue method and 1,1 diphenyl-2-picrylhydrazyl (DPPH) assay,
respectively. Analysis of physicochemical properties exhibited substantial variations
(p<0.05) in the levels of moisture, ash, protein, fat, carbohydrate, gross energy and pH of
raw and processed beans. Meanwhile, there was no considerable difference (p<0.05) in the
fibre content of fresh and processed beans. Investigation of total phenolic content showed
the significant (p<0.05) reduction of phenolic compounds in boiled (5.53±0.74 mg GAE/
g) and roasted (8.15±1.60 mg GAE/g) beans than raw samples (12.55±1.42 mg GAE/g).
DPPH radical scavenging activity was also decreased significantly (p<0.05) in boiled and
roasted samples with IC50 value of 0.0608±0.0765 mg/mL and 0.0523±0.0026 mg/mL,
respectively. In the case of household cooking, keeping boiling water would be advised
for the preservation of minerals, vitamins and phenolic compounds. The roasting process
may be used to develop high-quality health-promoting dark red kidney bean products.

Abstract
People in Bangladesh are traditionally used to consume mainly black tea. However, some
tea manufacturing companies are now producing green tea, though in a small scale. To
create new knowledge as well as awareness about the consumption of green tea, the
present study was carried out to compare the black and green tea available in Bangladesh
based on their bioactive compounds and antioxidant activity. A total of eight brands of
black tea and two brands of green tea were bought from the supermarkets. Total phenolics,
total tannin, total flavonoids, and caffeine content were measured as bioactive compounds,
and antioxidant activity was evaluated by using two different methods such as DPPH (1,1-
diphenyl-2-picrylhydrazyl) radical-scavenging activity and ABTS+ radical scavenging
activity of methanol extracts of black and green tea. Every bioactive compound in black
and green tea was found to be significantly different (P < 0.05). The total phenolic
content, on average, was measured at 242.46 mg GAE/g dry extract and 763.41 mg GAE/
g dry extract in black and green tea, respectively. Black tea contained 6.47 mg TAE/g dry
extract tannin, whereas green tea had much more tannin content, 14.51 mg TAE/g dry
extract, which is more than double in amount. On the other hand, the total flavonoid
content was almost double in black tea (61.82 mg QE/g dry extract) compared to green tea
(31.85 mg QE/g dry extract). Antioxidant activities were determined at different
concentrations of tea samples. At every concentration, green tea presented higher ABTS+
and DPPH radical scavenging activity than black tea. The highest percentage of inhibition
was observed at 20 ppm both in black and green tea, finding 98.50 % and 99.07 %
inhibition, respectively. Overall, significantly (P < 0.05) higher amount of phenolic
compounds as well as antioxidant activity were observed in green tea.

Abstract
BACKGROUND Cryopreservation is an effective tool for the preservation of live biological materials. OBJECTIVE This study examined the suitability of cryopreservation protocols and the effectiveness of ultrasound for silver carp embryos. MATERIALS AND METHODS Embryos at three developmental stages were exposed to 10, 15, 20, and 25% of five cryoprotectants (CPAs), namely propylene glycol (PG), dimethylformamide (DFA), DMSO, MeOH, and ethylene glycol (EG) for 20 min. Embryos were exposed to twelve vitrification solutions (VSs) for 10 (five steps of 2 min), 15 (five steps of 3 min), 20 (five steps of 4 min) min. Embryos were also exposed to ultrasound in VSs prior to cooling for cryopreservation. RESULTS Hatching rates decreased with increasing CPA concentrations while toxicity varied in the order of PG < DMSO < EG < MeOH < DFA. Tail elongation stage was more tolerant to CPA than 6-somites and morula stages. The survival of embryos exposed to ultrasound in VS was remarkably lower than in water. Embryos exposed to ultrasound in VSs under the best conditions did not response well after attempted vitrification. CONCLUSION Ultrasound-mediated CPA impregnation could be effective but other innovative methods may be needed to attain successful cryopreservation.

Abstract
There hasn't been a previous case report of the anterior interosseous nerve injury secondary to the presence of the muscle of Gantzer in a patient with myasthenia gravis in literature before. The anterior interosseous nerve compressive syndrome, also known as Kiloh-Nevin syndrome, is a rare disorder comprising less than 1% of all upper limb neuropathies. Establishing the etiology of anterior interosseous nerve compressive syndrome is challenging because of the lack of specific clinical findings or testing. Herein is the case of a 46 years-old male presented with left eye ptosis, ophthalmoparesis, diplopia, and right-hand weakness. On physical examination, the Pinch Grip test was positive. Electromyography studies showed neurogenic atrophy in the muscles innervated by the anterior interosseous nerve, as well as a pathological decrement of the muscle action potential of more than 10% on repetitive nerve stimulation. Concluding that the presence of the Gantzer muscle caused anterior interosseous nerve compressive syndrome was mainly a diagnosis of exclusion, after careful consideration of other possible etiologies including carpal tunnel syndrome, cervical radiculopathy, and Parsonage-Turner Syndrome. Even though anterior interosseous nerve compressive syndrome is very rare, clinical suspicion ought to arise in the presence of weak radial flexor digitorum profundus and flexor pollicis longus muscles. This case highlights the importance of a thorough medical history, a meticulous physical examination, and particularly the significance of electromyography studies in diagnosing different neuropathological entities. When appropriate, these steps offer information crucial to the differential diagnosis and eventual surgical management, assisting physicians in making informed and accurate treatment decisions.

Abstract
The mental health aspect of coronavirus disease-19 (COVID-19) patients in Bangladesh has remained less focused and has not been addressed properly. The objective of the study was to assess the levels of anxiety and depression in COVID-19 patients. We adopted a mixed online and telephone-based survey using Google Forms. Recruitment was performed through a snowball sampling approach. The Google Form was initially circulated in Facebook to identify interested participants. Then, three trained physicians interviewed the online responders over telephone for a period spanning from April 2020 to June 2020. Two well-known questionnaires, the Generalized Anxiety Disorder 7-item (GAD-7) scale and the Patient Health Questionnaire (PHQ-9), were used for the assessment of anxiety and depression, respectively. Here, the severity of anxiety was classified with the standard thresholds: minimal or none (0-4), mild (5-9), moderate (10-14) and severe (>15) for the GAD-7. Depression severity score: 0-4 was considered as none or no depression, 5-9: mild, 10-14: moderate, 15-19: moderately severe, 20-27 was for severe depression. A total of 237 patients were finally analyzed. The mean age ±SD of the patients was 41.59±13.73 years. Most of them were male (73%) and lived in urban areas (90.29%). Half of the patients were unemployed, and 17.7% admitted loss of job due to lockdown. The overall prevalence of anxiety and depression was 55.7% and 87.3%, respectively. The mean GAD-7 score was 5.79±4.95, and the mean PHQ-9 score was 5.64±5.15. Among the depressive patients, 3% had minimal depression, 38.4% had mild depression, 32.1% had moderate depression, 11.8% had moderate depression, and 2.1% had a severe depression. Similarly, 37.1%, 10.5% and 8% had mild, moderate and severe levels of anxiety, respectively. Nearly half of the study population (47.7%) was suffering from both depression and anxiety. Living in urban area was an independent predictor for depression (OR 3.882; CI: 1.249-12.069). Considering the high comorbid burden, the mental health issues of these patients need to be addressed and reinforced to the existing health system on a priority basis.
