Pyramiding of bacterial blight resistance genes into promising restorer BRRI31R line through marker-assisted backcross breeding and evaluation of agro-morphological and physiochemical characteristics of developed resistant restorer lines.

BRRI31R is one of the Bangladesh's most promising restorer lines due to its abundant pollen producing capacity, strong restoring ability, good combining ability, high outcrossing rate and genetically diverse from cytoplasmic male sterile (CMS) line. But the drawback of this line is that it is highly susceptible to bacterial blight (BB) disease of rice caused by Xanthomonas oryzae pv. oryzae. The present study highlighted the pyramiding of effective BB resistance genes (xa5, xa13 and Xa21) into the background of BRRI31R, through marker-assisted backcrossing (MABC). Backcross progenies were confirmed and advanced based on the foreground selection of target genes. Pyramided lines were used for pathogenicity test against five Bangladeshi Xanthomonas oryzae (BXo) races (BXo93, BXo220, BXo822, BXo826, BXo887) and confirmed the dominant fertility restore genes, Rf3 and Rf4 and further validated against SNP markers for more confirmation of target resistance genes. All pyramided restorer lines consisted of Xa4 (in built), xa5, xa13, Xa21, and Chalk5 with two fertility restorer genes, Rf3, Rf4. and these restorer lines showed intermediate amylose content (<25%). Restorer lines BRRI31R-MASP3 and BRRI31R-MASP4 showed high levels of resistance against five virulent BXo races and SNP genotyping revealed that these lines also contained a blast resistance gene Pita races. Gene pyramided restorer lines, BRRI31R-MASP3 and BRRI31R-MASP4 can directly be used as a male parent for the development of new BB resistant hybrid rice variety or could be used as a replacement of restorer line of BRRI hybrid dhan5 and 7 to enhance the quality of hybrid seeds as well as rice production in Bangladesh.

Detecting the provenance of price hike in agri-food supply chain using private Ethereum blockchain network.

The rise in the cost of essentials affects every nation around the world, but it has become a major concern for developing nations. It is getting increasingly difficult to keep up with rising prices for everyday items in these countries, where the majority of the population is from the middle class or lower middle class. Inflation, pandemics, wars, and other important variables all contribute to price increases. There may be another significant factor at play, which is supply-chain corruption. The supply chain's unreliable, chaotic, and opaque nature is to blame for this corruption. We are concentrating on the agri-food supply chain in our study. Because many of the current agri-food supply chains are intricate and challenging to monitor, dishonest parties can exploit the situation. Therefore, we suggested a thorough blockchain-based agri-food supply chain to identify the source of price increases. The private Ethereum blockchain was used in the suggested system. Since the private Ethereum blockchain is more efficient, safe, and fast, it was chosen. Smart contracts were created to describe the system and its underlying rules and laws. Furthermore, in order to showcase the usefulness of our smart contracts, we exhibited a sample decentralized application to support our hypothesis. We also gave the system a complete security and vulnerability assessment to make sure it is operating properly and is protected from threats and attacks. Due to the use of blockchain, the system is immutable, transparent, and simple to track and monitor. The proposed system has demonstrated greater transparency, traceability, reliability, speed, security, and cost-efficiency compared to conventional systems. It effectively traces the origin of corruption in the supply chain, providing a more straightforward means to tackle concerns related to price hikes.

Pharmacokinetic study of capivasertib and the CYP3A4 substrate midazolam in patients with advanced solid tumors.

PURPOSE: Capivasertib, a potent, selective inhibitor of all three AKT serine/threonine kinase (AKT) isoforms, is being evaluated in phase 3 trials in advanced breast and prostate cancer. This study evaluated the drug-drug interaction risk of capivasertib with the cytochrome P450 3A substrate midazolam in previously treated adults with advanced solid tumors. METHODS: Patients received oral capivasertib 400 mg twice daily (BID) on an intermittent schedule (4 days on/3 days off) starting on day 2 of cycle 1 (29 days) and on day 1 of each 28-day cycle thereafter. In cycle 1 only, patients received oral midazolam (1 mg) on day 1 (alone), and days 8 and 12 (3rd day off and 4th day on capivasertib, respectively). Midazolam pharmacokinetics on days 8 and 12 were analyzed versus day 1. Capivasertib, with or without standard-of-care treatment, was continued in patients deemed likely to benefit. Safety and exploratory efficacy analyses were conducted. RESULTS: Capivasertib-midazolam coadministration increased midazolam exposure (n = 21): geometric mean ratio (90% confidence interval) AUCinf and Cmax was 1.13 (0.97-1.32) and 1.15 (0.99-1.33) for day 8 versus day 1, and 1.75 (1.50-2.05) and 1.25 (1.08-1.46) for day 12 versus day 1. The capivasertib safety profile was manageable when administered with or without midazolam. Two patients had partial responses to treatment. CONCLUSION: The up to 1.75-fold increase in midazolam exposure indicates capivasertib is a weak CYP3A inhibitor at 400 mg BID on an intermittent schedule. Capivasertib was well tolerated; exploratory efficacy analysis demonstrated evidence of clinical activity in this heavily pre-treated population. CLINICALTRIALS: gov: NCT04958226.

Developing climate-resilient rice varieties (BRRI dhan97 and BRRI dhan99) suitable for salt-stress environments in Bangladesh.

Salinity variations are the main reason for rice yield fluctuations in salt-prone regions throughout the dry season (Boro season). Plant breeders must produce new rice varieties that are more productive, salt tolerant, and stable across a variety of settings to ensure Bangladesh's food sustainability. To assess the yield and stability, we used fifteen rice genotypes containing two tolerant checks BRRI dhan67, Binadhan-10 and the popular Boro rice variety BRRI dhan28 in different salinity "hotspot" in three successive years followed by additive main effects and multiplicative interaction (AMMI) model utilizing a randomized complete block (RCB) design with two replications. Parents selection was done based on estimated breeding values (EBVs). Eight parents with high EBVs (IR83484-3-B-7-1-1-1, IR87870-6-1-1-1-1-B, BR8992-B-18-2-26, HHZ5-DT20-DT2-DT1, HHZ12-SAL2-Y3-Y2, BR8980-B-1-3-5, BRRI dhan67, and Binadhan-10) might be used to develop new segregating breeding materials. Based on farmer preferences and grain acceptability, three genotypes (IR83484-3-B-7-1-1-1, HHZ5-DT20-DT2-DT1, and HHZ12-SAL2-Y3-Y2) were the winning and best ones. The above three genotypes in the proposed variety trial showed significantly higher yields than the respective check varieties, high salinity tolerance ability, and good grain quality parameters. Among them, HHZ5-DT20-DT2-DT1 and IR83484-3-B-7-1-1-1 harbored eight and four QTL/genes that regulate the valuable traits revealed through 20 SNP genotyping. Finally, two genotypes IR83484-3-B-7-1-1-1 and HHZ5-DT20-DT2-DT1 were released as high salinity-tolerant rice varieties BRRI dhan97 and BRRI dhan99, respectively in Bangladesh for commercial cultivation for sustaining food security and sustainability.

The effect of food and acid-reducing agents on the pharmacokinetic profile of capivasertib: Results from a randomized, crossover study.

AIMS: This two-part, adaptive study assessed the effect of food and an acid-reducing agent (rabeprazole) on the pharmacokinetics (PK) and safety of capivasertib, a potent AKT inhibitor, in clinical development for cancer treatment. METHODS: In Part 1, healthy participants (n = 24) were randomized to receive single-dose capivasertib after overnight fasting, a high-fat, high-calorie meal and with rabeprazole postovernight fasting in one of six treatment sequences. Based on Part 1 results, a new group of participants (n = 24) were randomized (Part 2) to receive capivasertib after overnight fasting, a low-fat, low-calorie meal and modified fasting (food restricted from 2 h before dosing to 1 h postdose) in one of six treatment sequences. Blood samples were collected for PK analyses. RESULTS: Following a high-fat, high-calorie meal, capivasertib exposure increased versus overnight fasting (geometric mean ratio [GMR] [90% confidence interval (CI)]: area under the concentration-time curve [AUCinf ] 1.32 [1.22, 1.43], maximum concentration [Cmax ] 1.23 [1.08, 1.41]), but was comparable to that postmodified fasting (GMR: AUCinf 1.13 [0.99, 1.29], Cmax 0.85 [0.70, 1.04]). AUCinf was similar and Cmax was lower with/without rabeprazole (GMR: AUCinf 0.94 [0.87, 1.02]), Cmax 0.73 [0.64, 0.84]). Capivasertib exposure was similar after a low-fat, low-calorie meal versus overnight fasting (GMR: AUCinf 1.14 [1.05, 1.25], Cmax 1.21 [0.99, 1.48]) or modified fasting (GMR: AUCinf 0.96 [0.88, 1.05], Cmax 0.86 [0.70, 1.06]). Safety was consistent with that in larger trials. CONCLUSIONS: This study demonstrates that administering capivasertib with food or acid-reducing agents does not lead to clinically relevant PK or safety profile changes.

GreenMolBD: Nature Derived Bioactive Molecules' Database.

BACKGROUND: One of the essential resources for developing new drugs are naturally derived biologically active lead compounds. Biomedical researchers and pharmaceutical companies are highly interested in these plant-derived molecules to develop the new drug. In this process, collective information of the plants and their phytoconstituents with different properties and descriptors would greatly benefit the researchers to identify the hit, lead or drug-like compound. AIM AND OBJECTIVE: Therefore, the work intended to develop a unique and dynamic database Green- MolBD to provide collective information regarding medicinal plants, such as their profile, chemical constituents, and pharmacological evidence. We also aimed to present information of phytoconstituents, such as in silico description, quantum, drugability and biological target information. METHODS: For data mining, we covered all accessible literature and books, and for in silico analysis, we employed a variety of well-known software and servers. The database is integrated by MySQL, HTML, PHP and JavaScript. RESULTS: GreenMolBD is a freely accessible database and searchable by keywords, plant name, synonym, common name, family name, family synonym, compound name, IUPAC name, InChI Key, target name, and disease name. We have provided a complete profile of individual plants and each compound's physical, quantum, drug likeliness, and toxicity properties (48 type's descriptor) using in silico tools. A total of 1846 associated targets related to 6,864 compounds already explored in different studies are also incorporated and synchronized. CONCLUSION: This is the first evidence-based database of bioactive molecules from medicinal plants specially grown in Bangladesh, which may help explore and foster nature-inspired rational drug discovery.

Comparison of transdermal fentanyl and oral tramadol for lateral thoracotomy in dogs: cardiovascular and behavioural data.

OBJECTIVE: To compare the analgesic efficacy and suitability of an existing oral tramadol-based protocol with a transdermal fentanyl-based protocol following lateral thoracotomy in dogs. STUDY DESIGN: Prospective randomized clinical trial. ANIMALS: A group of 16 healthy laboratory beagle dogs. METHODS: Dogs were randomly allocated to one of two treatment groups: group F (intramuscular methadone 0.2 mg kg-1 and transdermal fentanyl 2.6 mg kg-1 both administered on discontinuation of anaesthesia, n = 8) or group T (intramuscular methadone 0.2 mg kg-1 on discontinuation of anaesthesia and again 4 hours later, followed by oral tramadol 12 mg kg-1 per 24 hours commencing 7 hours after discontinuation of anaesthesia, n = 8). Intercostal bupivacaine (0.5-1 mg kg-1) and subcutaneous carprofen (4 mg kg-1) were administered to all dogs at induction. Body weight (BW), presence of clinical signs, pain score, activity, heart rate (HR) and mean arterial pressure (MAP) were assessed for 72 hours postoperatively. RESULTS: No significant differences were observed in BW change, presence of clinical signs or gross locomotor activity between groups. Pain scores were low at all times for all dogs, and rescue analgesia was not required. Dogs in group T exhibited higher pedometric activity (p = 0.006), HR (p < 0.001) and MAP (p < 0.001) than those in group F, in particular on night 1 following surgery. Least squared mean (LSM) pedometric activity was 1.81 and 1.02 jerks minute-1, LSM HR was 111.13 and 78.64 beats minute-1 and LSM MAP was 111.62 and 105.24 mmHg, respectively, in groups T and F. CONCLUSIONS AND CLINICAL RELEVANCE: Both regimes appear to provide adequate analgesia following lateral thoracotomy in dogs. Ease of administration of transdermal fentanyl compared to oral tramadol is advantageous. Reduced activity observed with the fentanyl regime was not associated with any adverse effects and may be desirable following some invasive surgeries. However, while transdermal fentanyl remains currently unavailable in the European Union, the oral tramadol-based regime provides an acceptable alternative.

Effects of In-country and Cross-Border Mobility on Condom Use Among Transgender Women (hijras) in Bangladesh: A Cross-Sectional Study.

In Bangladesh transgender women (hijras) are thought to be highly mobile that may be an impediment to condom use. This cross-sectional study was conducted to determine the extent of mobility of hijras, in-country and cross-border, and whether mobility affects condom use in anal intercourse. Hijras ≥15 years of age, receiving services from the Global Fund supported HIV prevention program were enrolled. A behavioral questionnaire was administered and blood was tested for antibodies to HIV and syphilis. Of 889 hijras sampled, 41.3 % never traveled, 26.4 % traveled in-country and 32.3 % crossed the border in the last year. HIV and active syphilis was at 0.8 and 1.8 % respectively. Among hijras who crossed the border condom use was less likely in last anal intercourse (AOR 0.68; 95 % CI 0.48-0.96), and consistently with new (AOR 0.59; 95 % CI 0.34-1.01) and regular clients (AOR 0.45; 95 % CI 0.27-0.76) in the last week. This study concludes that in Bangladesh hijras are highly mobile and cross-border mobility negatively affects condom use.

Clinical profile of HIV/AIDS-infected patients admitted to a new specialist unit in Dhaka, Bangladesh--a low-prevalence country for HIV.

This paper describes the clinical features of a series of patients admitted to the specialist HIV/AIDS unit (Jagori) of the Dhaka Hospital, ICDDR,B (International Centre for Diarrhoeal Disease Research, Bangladesh) during May 2008-February 2010. Data were collected from a review of documents and electronic case-records and collation of laboratory results with respect to CD4 counts. One hundred and nine patients were admitted during this period. Their mean age was 33.4 years, and 62% were male. On admission, the mean CD4 count +/- standard deviation (SD) was 244 +/- 245 (range 2-1,549). The death rate was 12%. The patients were classified as World Health Organization clinical stage 1: 23%, stage 2: 30%, stage 3: 23%, and stage 4: 24% during the admission. The commonest diagnosis recorded was tuberculosis (TB) (23%), which was also the commonest cause of death (38%). Even for those clinicians with limited experience of managing AIDS cases, the commonest problem encountered in this patient group was TB, reflecting the continued high burden of TB on health services in Bangladesh. Additional challenges to managing TB/HIV co-infection include atypical presentations in HIV-infected persons and the complex drug interaction with antiretroviral therapy.

Assessing public-private reproductive health efforts to reach young married couples in rural Bangladesh.

Young married couples (YMC) in Bangladesh receive insufficient attention from service providers for reproductive health and family planning needs. The ACQUIRE Project, undertaken by EngenderHealth, Bangladesh, provides intervention for service providers, social and local leaders, and mothers-in-law as effective agents of channeling information to YMCs. EngenderHealth, in collaboration with the public sector, examined the extent to which an intervention program enhances overall quality of services, respondents' knowledge and attitude, and service-seeking behavior related to reproductive health issues. A quasi-experimental design with two matching groups, one watching the intervention, was used. The endline survey was carried out 10 months after the Baseline survey. Key informants interviews and FGDs were conducted. The findings were mixed. Importantly, young married men and women need friendly services and service providers with positive attitudes.

Effect of corticosteroids on perinatal outcomes in preterm premature rupture of membranes.

This case control comparative study was done on 100 pregnant women both primi and multi with rupture membranes in two groups. These patients were admitted and treated in the Department of Obstetrics and Gynaecology in Sir Salimullah Medical College and Mitford Hospital, Dhaka, from July 2003 to December 2005. In this study, mean age of case group was 23.80 years (with corticosteroids) and 24.20 years in control group (without corticosteroids), with a range of 15-39 years. Here, out of 49 alive babies 15(30.82%) were affected by the consequences of PROM and birth process in case group and in control group, out of 48 alive babies 22(45.83%) were affected by the consequences of PROM and birth process. In corticosteroid group, 04 babies developed asphyxia & 05 developed neonatal sepsis otherwise in control group 08 babies developed asphyxia & 04 developed neonatal sepsis. So, on fetal outcome at this level in group with corticosteroids was better than without corticosteroids group. In this study, 12(24%) mother were affected by the consequences of PROM and corticosteroid therapy and majorities were chorioamnionitis (10%) and PPH (10%) and in control group 06(12%) were affected by the consequences of PROM and birth process. So, on maternal outcome at this level in control group (without corticosteroids) was better than case group. In this study effect of corticosteroids was evaluated on perinatal outcome in preterm premature rupture of membrane in developing country like Bangladesh & the effect of corticosteroids found better result on perinatal outcome but this apparent trend of the study could not be proved statistically.

Serologic evidence of dengue infection before onset of epidemic, Bangladesh.

Dengue fever emerged in Bangladesh in 2000. We tested 225 serum samples from febrile patients and 184 blood donors in 1996 and 1997 for dengue antibodies; 55 (24.4% ) febrile patients had dengue antibodies ( 65.5% with secondary infection pattern), compared with one (0.54%) donor (p <0.001), suggesting that dengue transmission was ongoing well before 1996.

Conservative management of eclampsia and severe pre-eclampsia--A Bangladesh experience.

OBJECTIVE: To observe whether the pregnancy can be safely continued for a reasonable period to gain fetal maturity in cases of eclampsia and severe pre-eclampsia. METHODS: Fifty-one patients were followed up in a specialized care (eclampsia) unit in Dhaka Medical College and Hospital between January 1998 and October 2000. Twenty-one patients with complaints of headache and blurred vision, and 30 patients with history of convulsion, all at gestational age < 36 weeks, were enrolled for this study. Magnesium sulfate was used to prevent convulsion in severe pre-eclampsia and to control convulsion in eclampsia. After conducting a baseline assessment, pregnancy was continued to gain fetal maturity. Patients were monitored closely. Diastolic blood pressure, 24-hour urinary total protein (UTP), and serum uric acid were chosen as the main parameters to detect the deterioration of a patient's condition. Pregnancy was terminated when deterioration occurred, as determined clinically or by 1 or more of the above parameters. Dexamethasone was used during the waiting period for fetal lung maturity. Patient outcomes were analyzed. RESULTS: At admission, the patients' mean gestational age ( SD) was 30.65 2.38 weeks, and the range was 24-34 weeks. Mean diastolic blood pressure was 109.06 11.61 mm Hg, 24-hour UTP was 2.25 1.73 g/24 h, and serum uric acid level was 5.5 1.12 mg/dL. Pregnancy was continued for a mean of 13.27 8.26 days (range, 3-35 days). Thirty-two babies (62.75%) with birth weight 1.0-2.5 kg (2.02 0.45) were born alive. Six of them (18.75%) weighing between 1.0 and 1.5 kg at birth were referred to the intensive care unit, and 1 (3.13%) weighing 1 kg at birth died within 5 minutes after birth. Among live-born babies, 93.75% were in good condition at the time of discharge from the hospital. Intrauterine death occurred in 19 (37.25%).cases. Twelve of them delivered spontaneously within 7 days of death and 7 required induction. In all cases, maternal condition was satisfactory. CONCLUSION: In carefully selected cases and with close supervision, pregnancy may be continued in women with eclampsia and severe pre-eclampsia to increase fetal maturity without increasing the risk to the mother.
