    Abstract The present study was conducted with the aim to reveal the effect of genotypes on reaction time, refractory period, semen index and liquid stored (at 4oC) semen quality of breeding bulls in Bangladesh. Semen was collected twice a week from Holstein Friesian, Sahiwal and Brahman breeding bulls. Reaction time and refractory period were examined for the breeding bulls. Semen volume, sperm concentration and total spermatozoa/ejaculate were measured immediately after collection. It was revealed that genotype had a significant (P [Fundam Appl Agric 2023; 8(3.000): 555-566]

    Abstract Arsenic contamination is a global health concern, primarily through contaminated groundwater and its entry into the food chain. The association between arsenic exposure and cardiovascular diseases (CVDs) is particularly alarming due to CVDs being the leading cause of death worldwide. Arsenic exposure has also been linked to changes in telomere length, mitochondrial DNA copy number (mtDNAcn), and deletion, further increasing the risk of CVDs. We aimed to determine whether arsenic exposure alters telomere length and mtDNAcn and deletion in a total of 50 CVD patients who underwent open heart surgery hailed from known arsenic-affected and unaffected areas in Bangladesh. Amount of arsenic was determined from the collected nails and cardiac tissues. Relative telomere length and mtDNAcn and deletion were quantified by qRT-PCR. The patients from arsenic-contaminated areas had higher average arsenic deposits in their fingers and toenails (P < 0.05) and higher cardiac tissue injury scores (P < 0.05). Moreover, approximately 1.5-fold shorter telomere length (P < 0.05, r =  - 0.775), 1.2-fold decreased mtDNAcn (P < 0.05, r = - 0.797), and an 81-fold higher amount of mitochondrial DNA deletion (P < 0.05, r = 0.784) were observed in the patients who had higher arsenic deposition in their nails. Higher levels of arsenic exposure were found to be linked to shorter telomere length, decreased mtDNAcn, and increased mitochondrial DNA deletion in the patients from As-affected areas. It can also be anticipated that the correlation of arsenic exposure with telomere length, mtDNAcn, and deletion can be used as biomarkers for early diagnosis of arsenic-induced cardiovascular diseases.

    Abstract The novel coronavirus 2019 disease (COVID-19) is now in an outbreak not only in China but also around the world, suspected to be originated from a wet market in Wuhan, Hubei province, China. The flare-up of COVID-19, it has already been infected 78,811 people with 2462 fatalities in 1 month window. The most alarming issue is the virus can transmit from host to host and still asymptomatic. Currently, 24 counties with 505 confirmed cases have been reported. Presently, there is no specific treatment or vaccine but physicians are battling with the use of antibiotics, steroid, anti-viral and anti-HIV drugs and some of the infected cases are testified improved. WHO and China National health Commission are cooperatively striving to come up with elucidation but it will take a minimum of 3 to 4 months at least to undergo a phase-1 trial. However, the soaring rates of spreading each day has become much stable which might even improve within the next few weeks in China but not for some other countries. Healthy peoples are instructed to avoid public gathering, always wearing the mask and frequently wash hands. Currently, China has able to hold up more than 97.7% infection within China but a scientific breakthrough is crucial before it's too late.

    Abstract Persistent organic pollutants (POPs) are increasing in waterways due to human activities and their concentration above a certain level is highly toxic with acute damage. In this manuscript, we have compiled the data of these POPs in Chinese freshwater channels, lakes, and corresponding coastal areas from the studies performed in the last twelve years. All the water channels were contaminated with Polyaromatic hydrocarbons (PAHs), Organo-chlorine pesticides (OCPs), and Polychlorinated biphenyls (PCBs). Although most of these water channels maintain the GB5749–2006 guideline for POPs, Liaohe River, Huaihe River, Yangpu Bay, Taihu Lake, Liuzhou surface water, Pearl River Estuary, and Jinzhou Bay have toxicity levels and the maximum concentration of these POPs is above the defined safe limits. Pharmacokinetic data for thirty-eight POPs by SwissADME showed that they are highly penetrable through the skin (Log Kp -6.02 to 0.15) and orally absorbable (bioavailability score 0.55). Therefore, these waterways have acute damaging potential. This indicates that using these water channels for municipal supplies might lead to massive health hazards. Therefore, careful mapping and treatment are necessary before the utilization of water from these water reservoirs.

    Abstract Acetaminophen (APAP) is the most popular mild analgesic and antipyretic drug used worldwide. APAP overdose leads to drug-induced hepatotoxicity and can cause hepatic failure if treatment delayed. It is adequately comprehended that the metabolism of high-dose APAP by cytochrome P450 enzymes generates N-acetyl-p-benzoquinone imine (NAPQI), a toxic metabolite, which leads to glutathione (GSH) depletion, oxidative stress, and activation of various complex molecular pathways that initiate liver injury and downstream hepatic necrosis. Administration of activated charcoal followed by N-acetylcysteine (NAC) is considered the mainstay therapy; however, including side effects and limitation of rescuing for the delayed patients where liver transplantation may be a lifesaving procedure.

    Abstract Background Progression of Benign Prostate hyperplasia (BPH) is vulnerable to oxidative stress (OS) and prostatic enlargement among the aging males through apoptosis deregulation. Our present study aimed to investigate the effect of neferine (NF) in the regulation of oxidative stress and apoptosis in human BPH-1 cells. Methods BPH epithelial cell line BPH-1 was treated with NF for 24 and 48 h. To measure oxidative stress (OS) we investigated MDA, SOD, and GST expression along with Nrf2 and its downstream gene and protein expression. Cell proliferation and apoptosis regulation was assayed with respective methods. Results Investigation revealed NF remarkably activate Nrf2 and its downstream proteins HO-1 and NQO1 at 48 h more substantially. Nrf2/Keap1 relative gene and protein expression indicated that NF might trigger Nrf2 upregulation by decreasing Keap1 expression. Both NF concentrations (3 µM and 9 µM) were able to deplete ROS and lipid peroxidation, concurrently, up-regulated SOD and GST. NF reduced cell proliferation significantly along with the regulation of apoptotic proteins Bax, Bcl2, Cyt-C, Caspase 9, and Caspase 3 at the same time (48 h). Conclusion This study is the first to manifest that NF may potentially regulate BPH by counterbalancing between OS and apoptosis through the activation of Nrf2-ARE pathway.

    Abstract Background: During the COVID-19 pandemic, dental education institutions throughout the world experienced significant challenges, including a quick shift to an online learning paradigm. Since the pandemic has had a considerable impact on dental education, this research evaluated the perspectives and attitudes towards online learning among undergraduate dental students in Bangladesh.
    Methods: The research was conducted through a cross-sectional method using self-administered online questionnaires. The questionnaire included information on the students' sociodemographic status, their views, and their attitudes about the changes in the educational system, specifically regarding online learning. The study gathered data from 952 undergraduate students from 14 dental institutions in Bangladesh.
    Results: The results suggested that 87.5% of all the students were unsatisfied with their online programs. Most of the respondents who expressed dissatisfaction with their online classes were female, did not receive assistance in overcoming barriers to accessing the classes or materials (64.23%), did not have access to the institutional online-learning management system (OLMS) (67.35%), and did not have access to the online course materials (71.43%). The students considered that the shift to online learning failed to provide quality clinical teaching.
    Conclusions: The lack of an OLMS was found to be linked with dissatisfaction with online learning among Bangladeshi dental students during the COVID-19 outbreak. Additionally, insufficient time allocation and a lack of support through online training were found to be strongly correlated with the students' discontent. The overall findings highlight the need to develop and implement effective online dentistry educational interventions to promote academic advancement and key practical skills.

    Abstract Based on self-assembly amplification, we designed a novel microRNA (miRNA)-detection method with high specificity and sensitivity. Two unique DNA probes named Linker A and Linker B were modified with phosphorothioate (PS) at both ends. In the presence of the target miRNA, these two DNA probes were ligated together by T4 DNA ligase enzyme to form a dumbbell-shaped DNA. Then the dumbbell-shaped structure would be extended with Bst 2.0 DNA polymerase enzyme, triggering the strand displacement activity without using additional primers. These results revealed our method's ultralow detection limit (300 fM), excellent selectivity, simple operation, and capability to discriminate single-base mismatches. It is believed that this proposed approach would have great application potential in clinical diagnosis and other involved fields.
