Abstract
Western flower thrips, Frankliella occidentalis, is a serious pest by directly infesting host crops. It can also give indirect damage to host crops by transmitting a plant virus called tomato spotted wilt virus. A fungal pathogen, Beauveria bassiana, can infect thrips. It has been used as a biopesticide. However, little is known on the defense of thrips against this fungal pathogen. This study assessed the defense of thrips against the fungal infection with respect to immunity by analyzing immune-associated genes of F. occidentalis in both larvae and adults. Immunity-associated genes of western flower thrips were selected from three immunity steps: nonself recognition, mediation, and immune responses. For the pathogen recognition step, dorsal switch protein 1 (DSP1) was chosen. For the immune mediation step, phospholipase A2 (PLA2) and prostaglandin E2 synthase were also selected. For the step of immune responses, two phenoloxidases (PO) genes and four proPO-activating peptidase genes involved in melanization against pathogens were chosen. Dual oxidase gene involved in the production of reactive oxygen species and four antimicrobial peptide genes for executing humoral immune responses were selected. All immunity-associated genes were inducible to the fungal infection. Their expression levels were induced higher in adults than in larvae by the fungal infections. However, inhibitor treatments specific to DSP1 or PLA2 significantly suppressed the inducible expression of these immune-associated genes, leading to significant enhancement of fungal pathogenicity. These results suggest that immunity is essential for thrips to defend against B. bassiana, in which DSP1 and eicosanoids play a crucial role in eliciting immune responses.

Abstract
The singly Cabibbo-suppressed decay Λ_{c}^{+}→nπ^{+} is observed for the first time with a statistical significance of 7.3σ by using 3.9 fb^{-1} of e^{+}e^{-} collision data collected at center-of-mass energies between 4.612 and 4.699 GeV with the BESIII detector at BEPCII. The branching fraction of Λ_{c}^{+}→nπ^{+} is measured to be (6.6±1.2_{stat}±0.4_{syst})×10^{-4}. By taking the upper limit of branching fractions of Λ_{c}^{+}→pπ^{0} from the Belle experiment, the ratio of branching fractions between Λ_{c}^{+}→nπ^{+} and Λ_{c}^{+}→pπ^{0} is calculated to be larger than 7.2 at the 90% confidence level, which disagrees with most predictions of the available phenomenological models. In addition, the branching fractions of the Cabibbo-favored decays Λ_{c}^{+}→Λπ^{+} and Λ_{c}^{+}→Σ^{0}π^{+} are measured to be (1.31±0.08_{stat}±0.05_{syst})×10^{-2} and (1.22±0.08_{stat}±0.07_{syst})×10^{-2}, respectively, which are consistent with previous results.

Abstract
Thyroid swellings are common clinical problem throughout the world and also in Bangladesh. Most of thyroid swellings are multinodular, but a good percentage is solitary thyroid nodule. There is no robust, feasible method for malignancy differentiation has not been well established. The study evaluated thyroid nodules for risk of malignancy and compared history, clinical, sonographic features and FNAC findings with histopathology. This was a cross sectional study on 160 consecutive subjects of thyroid nodules done in the department of ENT and Head Neck Surgery of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh during from July 2018 to December 2019. All patients were admitted and diagnosed by detail history, clinical examination, investigations and underwent thyroidectomy. Detailed history, clinical examination, ultrasonographic finding and FNAC variables were documented retrospectively and a mathematical model was established for malignancy prediction. In this study mean age of the patients of thyroid nodules was 37.54±11.49 years and majority of the patients were within 21-40 years of age. Frequency of thyroid nodules is more in female with male female ratio 1:7. Most of the thyroid nodules appeared in this study within 0-2 years (61.9%). In this series of thyroid nodules constituted 88.1% firm, 8.8% hard, 3.1% cystic. Among the patients 89(55.6%) cases have solitary thyroid nodule and 71(44.4%) cases have multinodular goitre Majority of the nodules were warm 57.5% followed by cold 42.5%. FNAC showed nodular goitre 72.5%, Follicular neoplasm 1.3%, Papillary carcinoma of thyroid 7.5%, colloid goitre 9.4%, suspicious papillary carcinoma 3.8% and lymphocytic thyroiditis 1.3%. In this study out of 85 solid nodule, 69(81.18%) were benign and 16(18.82%) was malignant and out of 3 cystic nodule 3(100%) were benign. In this study most of the benign and malignant nodules were predominantly solid. Study showed the malignancy is significantly (p=0.001) more in solid than cystic nodules. Final diagnosis in this study was done on the basis of histopathological reports. Out of 160 patients, histopathologically benign lesion was 120(75%) and malignant was 40(25%). Among malignant cases 36(22.5%) cases were papillary carcinoma, 1 case was medullary carcinoma and 3 cases were follicular carcinoma.

Abstract
Tuberculosis (TB) is a global threat with a large burden across the continents in terms of mortality, morbidity, and financial losses. The disease has evolved into multi-drug-resistant (MDR-TB) and extensively drug-resistant (XDR-TB) tuberculosis owing to numerous factors ranging from patients' non-compliance to demographical implications. There have been very few new drugs for resistant TB. Resistance has already been reported even for the newly introduced drug bedaquiline. An attempt has been made to integrate both structure-based and QSAR drug design techniques (QSAR-SBDD) for the identification of novel leads. The docking scores normally do not correlate with the activity. Hence, the docking results have been analysed in terms of the number of interactions rather than docking scores. The parameters derived from interactions have been used in developing the QSAR models. The best model shows a good correlation (r = 0.908) between the activity and interaction parameter 'C' describing the sum of all the interactions with each amino acid residue. This model also predicts external dataset with a good correlation (rext = 0.851) and can be used for the identification of novel chemical entities (NCEs) and repurposed drugs for TB therapeutics.

Abstract
BACKGROUND : TB was the leading cause of death from a single infectious pathogen globally between 2014 and 2019. Fine-scale estimates of TB prevalence and case notifications can be combined to guide priority-setting for strengthening routine surveillance activities in high-burden countries. We produce policy-relevant estimates of the TB epidemic at the second administrative unit in Bangladesh. METHODS : We used a Bayesian spatial framework and the cross-sectional National TB Prevalence Survey from 2015–2016 in Bangladesh to estimate prevalence by district. We used case notifications to calculate prevalence-to-notification ratio, a key metric of under-diagnosis and under-reporting. RESULTS : TB prevalence rates were highest in the north-eastern districts and ranged from 160 cases per 100,000 (95% uncertainty interval [UI] 80–310) in Jashore to 840 (UI 690–1020) in Sunamganj. Despite moderate prevalence rates, the Rajshahi and Dhaka Divisions presented the highest prevalence-to-notification ratios due to low case notifications. Resolving subnational disparities in case detection could lead to 26,500 additional TB cases (UI 8,500–79,400) notified every year. CONCLUSION : This study is the first to produce and map subnational estimates of TB prevalence and prevalence-to-notification ratios, which are essential to target prevention and treatment efforts in high-burden settings. Reaching TB cases currently missing from care will be key to ending the TB epidemic.

Abstract
Rickettsial diseases are one of the leading causes of treatable acute febrile illness in Asia pacific region. This cross-sectional descriptive study was conducted at Department of Microbiology, Mymensingh Medical College to diagnose scrub typhus by rapid Immunochromatographic Test (ICT) and Nested PCR followed by molecular identification of possible Rickettsial coinfection among suspected febrile patients in Mymensingh, Bangladesh from March 2019 to February 2020. Among the enrolled 402 patients, 89 samples (22.13%) were seropositive by Immunochromatographic Test (ICT) and 65 samples (16.16%) were positive for O. tsutsugamushi DNA by Nested PCR, targeting 47KDa gene. Therefore, 113/402 (28.10%) samples were positive for scrub typhus by PCR and/or ICT. All the scrub typhus positive samples were further subjected to Nested PCR targeting 17 KDa gene for identification of Rickettsial co-infection and 13/113 (11.50%) were documented as positive. Then 13 Rickettsial co-infected samples were undertaken to automate sequencing and all were genetically confirmed as Rickettsia felis. Findings of the study may help clinicians to expand their list of differential diagnoses for undifferentiated fever and detection of Rickettsial co-infection may guide them to prescribe effective antimicrobials.

Abstract
Present research work represents antiviral and antibacterial value of body fat of Saara hardwickii commonly called as spiny tailed lizard. Oil was extracted from body fats located in the ventral region of this animal using hydrocarbons e.g., n-hexane, methanol, butanol and ethyl acetate as a solvent. The antibacterial activity of lizard oil was tested against standard as well as multi-resistant lines ofEscherichia coli, Styphalococcus aureus, Pseudomonas aeruginosa and Proteus vulgaris alone and with antibiotic ampicillin. For antibacterial potential, Ethyl acetate and Butanol solvent extract showed best zone of inhibition (7mm) with P. aeruginosa and S. aureus respectively. For antiviral potential, Butanol and Methanol extract showed best HA (Hemagglutination) titer of 04 with NDV and IBV viral strain respectively. It is concluded that lizard oil has antimicrobial potential against different pathogens strains (virus, bacteria).

Abstract
Background: People with chronic rhinosinusitis may be referred for endoscopic sinus surgery (ESS), a procedure commonly performed under general anaesthesia, once maximal medical therapy has failed. A new pathway of care is emerging: Local Anaesthetic Nose & Sinus Surgery (LANSS). With LANSS the patient is not placed under general anaesthesia, but instead the procedure is performed under a local anaesthetic. Methodology: A decision analytic model was developed from the perspective of the UK National Health Service (NHS) to assess the potential cost impact of LANSS versus current standard care pathway for ESS. Results: Modelling indicated that the introduction of LANSS would generate substantial savings of around £84,500 per year if introduced to a typical NHS trust with a large otolaryngology department undertaking 300 ESS procedures per year. These savings are generated as a proportion of the ESS procedures no longer need to be completed in an operating theatre, which reduces operational costs (saving around £64,500 per year), plus the use of local anaesthetic instead of general anaesthetic and a reduction in the time a patient spends as an inpatient. Conclusions: The uptake of LANSS could generate cost-savings of around £84,500 per year to a typical NHS trust in the UK.

Abstract
Using a data sample corresponding to an integrated luminosity of 2.93 fb^{-1} collected at a center-of-mass energy sqrt[s]=3.773 GeV by the BESIII detector, the decay D^{0}→ωϕ is observed for the first time. The branching fraction is measured to be (6.48±0.96±0.40)×10^{-4} with a significance of 6.3σ, where the first and second uncertainties are statistical and systematic, respectively. An angular analysis reveals that the ϕ and ω mesons from the D^{0}→ωϕ decay are transversely polarized. The 95% confidence level upper limit on longitudinal polarization fraction is set to be less than 0.24, which is inconsistent with current theoretical expectations and challenges our understanding of the underlying dynamics in charm meson decays.

Abstract
Scrub typhus is one of the leading causes of undifferentiated treatable febrile illness in Asia pacific region. It is grossly under diagnosed in many tropical countries of South Asia including Bangladesh, due to wide range of non-specific clinical presentations, low index of suspicion among clinicians, limited awareness and lack of accurate diagnostic facilities. This cross sectional observational study was conducted at department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from March 2019 to February 2020 enrolling 113 diagnosed cases of scrub typhus by Immunochromatographic test (ICT) and / or Nested PCR to characterize the socio-demographic and clinico-epidemiological features of scrub typhus in Mymensingh area. Majority of the scrub typhus cases came from rural areas (63.83%) and there was a slight female predominance (52.21%). The young (32.74%) and the young-adult age group (28.31%) were mostly affected. Most of the scrub typhus cases were housewives (30.98%), followed by farmers (23.89%) and students (21.23%). All the enrolled cases presented with fever. Other findings were myalgia (76.10%), headache (56.63%), cough (30.97%), vomiting (12.38%) and Respiratory distress (9.73%). Typical eschar of scrub typhus was present only in 9(7.96%) cases and 4(3.53%) patients had rashes on their skin. Few cases (3.53%) had jaundice and 15.96% cases were anaemic. Oliguria (7.96%) and neck rigidity (1.76%) were also documented. Most of the Nested PCR positive scrub typhus cases were documented during late rainy season and beginning of winter months. Findings of the study may offer increased awareness about high burden of scrub typhus as well as heightened suspicion among clinicians for early diagnosis, timely treatment and prevention of complications.

Abstract
Antimicrobial resistance mediated by extended-spectrum beta-lactamases (ESBL), AmpC beta-lactamase and metallo-beta-lactamase (MBL) producing Acinetobacter species is an emerging problem worldwide. In this cross-sectional study total 341 specimens were collected over a period of one year from January 2017 to January 2018. Specimens were collected from ICU and Surgery unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Specimens were collected from ICU and Surgery Unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Samples were processed for culture by standard conventional methods and susceptibility testing and determined by Kirby Bauer disc diffusion method. Antibiotic discs and their strength were according to the CLSI 2017 guideline. Molecular study was done to detect the species by OXA-51 gene and drug resistance genes (IMP, VIM, NDM, TEM, SHV, CTX, SPM, SIM and GIM). Species identification was done by OXA-51 gene which is intrinsic to Acinetobacter baumannii. Among the 46 isolates, 36(78.26%) were positive for Oxa-51 gene, 16(34.8%) for TEM gene, 9(19.6%) for VIM gene, 3(6.5%) for NDM gene and 1(2.2%) for IMP gene. This study gives an alarming sign towards high prevalence of cephalosporin and carbapenem resistance due to production of extended spectrum beta-lactamases and metallo-betalactamases, respectively. Early detection, proper antibiotic policies, and compliance towards infection control practices are the best defenses against these organisms.

Abstract
Among the quinolones, fluoroquinolones are broad spectrum antimicrobial agents used for treating many clinical infections including Salmonellosis. Although high level of resistance to fluoroquinolones remains low in Salmonella but reduced susceptibility is increasing worldwide. Plasmid-mediated quinolone resistance (PMQR) of qnr type (qnrA, B and S) has been identified now a day in several enterobacterial species including Salmonella spp. This cross-sectional study was held at department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from March 2019 to February 2020. This study was conducted to determine the current quinolone resistance pattern and to detect the presence of qnrA, qnrB and qnrS genes among Salmonella isolates. Antimicrobial susceptibility test of 36 Salmonella isolates were done by disc diffusion method. MIC of ciprofloxacin was detected by agar dilution method. Then amplification with specific primers of qnrA, qnrB and qnrS genes were performed for all Salmonella isolates. The present study observed 80.5% resistance to nalidixic acid, 33.3% to ciprofloxacin and 19.4% to ofloxacin by disc diffusion method. qnr A gene was detected in 2(5.5%) isolates, where as qnrS was detected in 5 (13.8%) isolates. None of the isolates was positive for qnrB gene. All the qnrA positive isolates showed resistance to Ciprofloxacin (MIC=128μg/ml) and Ofloxacin. In conclusion, presence of qnr genes in the study isolates is alarming, because, rapid dissemination might occur due to conjugative plasmid mediated horizontal transfer.

Abstract
Zinc is one of the important trace elements of blood. It helps in maturation of immune system in our body. In the past studies originate the relationship between viral disease and serum zinc deficiency. This was a multicenter case-control study to measure the serum zinc level of COVID-19 patients with different respiratory supports and to evaluate the Odds Ratio (OR) and Relative risk (RR) of zinc deficiency for oxygen requirement for COVID-19 patients. Study places were COVID-19 unit of three tertiary hospitals of Sylhet, a Northern district of Bangladesh. There were 30 controls and 90 cases in this study. The mean zinc level of cases (53-38mcg/dl) was significantly (p=0.000072) lower than the level of controls (73-23mcg/dl). The mean zinc level of the COVID-19 patients required oxygen (49-33mcg/dl) was significantly (p=0.0054) lower than the patients were not treated by oxygen therapy (64-51mcg/dl). The RR of getting affected by COVID-19 was 1-91 for the low zinc level people. Among the COVID-19 affected participants the lower zinc level people had a RR of 1-93 to receive oxygen supplementation. Lower zinc level people are more likely to be affected by COVID-19 in comparison to the normal zinc level people. Among the COVID-19 patients the lower zinc level people had nearly double (RR 1-93) risk of becoming hypoxic and eventually prone for oxygen support.
