Biomineralization is the process by which living forms influence the precipitation of mineral materials. It provides organisms with skeletons and shells while they are alive and when they die they are deposited as sediment in environment from river, plants to the deep ocean floor. Biomineralization process is controlled by various factors like temperature, Organic matrix, additives, pH etc. Variety of applications of Biomineralization based technology in the construction has been reported. The Biomineralization is a multidisciplinary research area which briefly documents the future directions of the technology toward commercial scale applications.

Maxillary defects can occur due to certain bacterial, fungal and viral infections. But in recent time mucormycosis has become prevalent secondary to covid-19 infection. Mucormycosis is an opportunistic fungal infection, which primarily affects diabetic and immunocompromised patients. Surgical excision and debridement of the affected areas can result in significant defects. Reconstruction and rehabilitation of these defects remains a significant challenge for the clinicians because 3-D anatomy of the maxilla serves speech, swallowing and aesthetic roles. This review article discusses the reconstructive and rehabilitative methods of mucormycosis maxillary defects.

Introduction: Amniotomy is an artificial rupture of the egg's membranes using a membrane piercer through the cervical opening of the uterus. It is an invasive method of induction and stimulation of labour that may increase the risk of complications during labour and early postpartum. Objective: to evaluate the impact of amniotomy on maternal and fetal outcomes during labor, delivery, and early postpartum. Methods: This was a case-control study with retrospective data collection over a period of 6 months from March to August 2017 at the maternity ward of the Gynaecological-Obstetric and Paediatric Hospital in Yaoundé. Women who received amniotomy (exposed group) were compared to those who did not receive amniotomy (unexposed group). The data collected were entered and analyzed on Epi-info 3.5.1 and Statistical Package For Social Science SPSS 20.0 software. Comparison of variables was done using Chi-square (X2) and Fisher's exact test. The association between amniotomy and the different variables was measured using the relative risk (RR) and its 95% confidence interval (CI). P < 5% was considered significant. Results: A total of 193 deliveries were recorded and divided into 110 cases of amniotomy and 83 spontaneous rupture of membranes. The frequency of amniotomy was 76.92% in our study. Maternal complications occurred in 38.2% of cases in the amniotomy group and in 32.5% of cases in the second group with a P value of 0.255 (not significant). Fetal and neonatal complications occurred in 13.6% of cases of amniotomy and 21.7% of spontaneous rupture of membranes during labour and 13 cases of amniotomy versus 11 cases of spontaneous rupture of membranes in the early post partum period. The difference was not statistically significant between the two groups for the occurrence of complications (P=0.410). Conclusion and recommendation: At the end of our study, it appears that amniotomy is very frequent in our environment, but its realization has no proven impact on the fate of the mother and the fetus.

This study investigated the effect of peer assessment in Oral English achievement of senior secondary school students in Bayelsa State and the moderating influence of learning style. The study used the quasi-experiment research design. The population for this study consisted 24,769 senior secondary school II students in Bayelsa state. The sample for this study consisted of 360 senior secondary school students in class 2 (SS2) of public secondary schools in Bayelsa State, Nigeria. Two instruments were used for the study. They were the ‘Oral English Achievement Test (OEAT)’ and the VARK Questionnaire. “The Oral English Achievement Test (OEAT) contained 25 standardized multiple choice items and was marked over 100. On the other hand, the VARK scale was a multivariate instrument with four subsections that measured the student’s method of learning. It was composed of 32 items with 8 items in each sub-sections. Face and content validity of the instrument was determined by giving it to three experts in Measurement and Evaluation specialty in the Department of Educational Psychology, Guidance and Counselling in University of Port Harcourt. Reliability of the instrument was determined using KR20. After analysis, a reliability coefficient of 0.79 was realized indicating that the instrument was highly reliable. On the other hand, the reliability of VARK was established using Cronbach Alpha method of reliability with an index of 0.80. Mean, standard deviation, and, paired sample t-test and ANCOVA were used to analyze the data. Findings revealed that there is a significant difference in achievement of students in peer-assessment group (p=0.001<0.05). Based on these finding, it was recommended among others that student should be encouraged by the classroom teacher to carry out peer-assessment from time to time since it has been seen that it improves the achievement of student especially in oral English.

Background: The adoption of digital resources and tools at the secondary level has been a popular strategy for improving student engagement and achievement. In rural and semi-urban districts such as Osmanabad, in Maharashtra, the use of technology like smartboards, e-learning, and the blended classroom model is an indication of the educational opportunity and systemic challenge at the same time. This research aims to understand how these tools impact students’ learning within the context of the localized educational and infrastructural realities of the area. Objective: This study aimed to explore the academic influence of three main digital interventions, viz, smartboards, e-learning apps, and blended classrooms in the secondary education of students (Grades 9-10) in the Osmanabad District. It attempted to determine the effectiveness of these tools and the contextual factors that mediated their success, including the accessibility, teacher facilitation, and student motivation. Methods: Using a qualitative-descriptive method, data were generated via semi-structured interviews with 10 teachers and 80 students, and 6 non-participant classroom observations in 6 schools. The method of thematic analysis was adopted to aggregate repetitive patterns and draw an interpretive understanding. Results: It shows the smartboards facilitated concept applications and active student participation, especially in Mathematics and Science. E-learning applications were valuable to students as they enabled self-based learning, albeit constrained by access deprivation. Mixed classrooms proved to be the best model, mixing flexibility with ongoing contact with the teacher. Yet digital inequity, poor infrastructure, and differences in pedagogical preparedness determined these on the whole. Conclusion: In summary, digital learning tools have the potential to significantly boost academic outcomes, but the payoff is greatest when the tools are pedagogically integrated, equitably available, and supported by trained educators. The findings of this study have implications for policy interventions that need to strike a balance between the advancement of technology and human-centred support for learning, particularly in underprivileged areas such as Osmanabad.

Ticks are a significant impediment to the establishment of cattle production units in West Africa, notably in Côte d'Ivoire. A research was conducted at the Yamoussoukro Dairy Station from April to July 2020 to help in the battle against ticks and tick-borne diseases. A total of 1560 ticks were collected from cattle at the indicated station, subdivided into three genera (Boophilus, Amblyomma, and Hyalomma) and four species (R. (B) microplus, R. (B) annulatus, A. variegatum, and H. truncatum). R. (B) microplus was the most prevalent species (48.08 %). The most common species (63.40 %), the most infesting (3.87 ticks/cattle), and the most active (6.10 ticks/cattle) among the cattle at the station were R. (B) microplus. The most common, most numerous (1.63 and 1.62 ticks/cattle), and most active (3.18 ticks/cattle) species among the N'Dama and Zebu were R. (B) microplus (52.73 %) and A. variegatum (50.91 %). The species R. (B) microplus and R. (B) annulatus infest Metis animals significantly. These species have the highest incidence of infection and severity of an attack. In terms of parasite intensity, there was a positive association between R. (B) microplus and R. (B) annulatus.

Background: Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age, often linked to weight gain and metabolic issues. Managing weight effectively reduces PCOS symptoms and enhances reproductive and metabolic health. This study seeks to assess the effects of a structured weight management program on clinical and metabolic parameters in women with PCOS. Methods: This pre-and post-observational study was conducted at Bangabandhu Sheikh Mujib Medical University, Bangladesh, from January 2016 to December 2019. A total of 200 women diagnosed with PCOS are included in this study. Data were collected before and after a 12-week intervention focused on lifestyle modification, including dietary counselling and physical activity. Anthropometric, clinical, and metabolic variables were assessed. Data analysis was performed using SPSS (version 25.0). Paired t-tests were used to compare pre-and post-intervention outcomes, with a significance threshold of p < 0.05. Results: Significant post-intervention improvements were observed in the metabolic, hormonal, menstrual, and psychological parameters in women with PCOS. Reductions were noted in fasting glucose (4.9 ± 0.7 mmol/L), insulin (10.4 ± 3.8 μU/mL), and total testosterone (1.8 ± 0.3 nmol/L). Ovulation frequency increased (3.2 ± 1.7 cycles/year), while depression and anxiety scores significantly declined (p < 0.01 across parameters). Conclusion: A structured weight management approach effectively enhances clinical symptoms and metabolic profiles in women with PCOS. These results highlight the significance of lifestyle intervention as a primary treatment strategy in managing PCOS.

Delta variant is a variant of concern that WHO is tracking and monitoring around the world. It's a variant of concern because we know it has increased transmissibility. This has been demonstrated by several countries. And we know that where the Delta variant is identified, it really rapidly takes off and spreads between people more efficiently than even the Alpha variant that was first detected around December, January 2021. This review highlights the emergence of Delta variant among Indian populations.

Background: Blood transfusions, crucial for emergency obstetric care, can significantly reduce maternal mortality rates. Obstetric transfusions are often urgent and unpredictable. Common emergencies include hemorrhages from ectopic pregnancy, abortions, and placenta previa. Transfusion rates vary globally, with 0.2%-3.2% in high-resource countries and higher in low-resource areas. Despite their benefits, transfusions carry risks such as allergic reactions and infection transmission. Aim of the study: The study aims to ascertain the indications and risk factors associated with blood transfusions in obstetric and gynecological patients. Methods: This retrospective observational study at the Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, analyzed indications and risk factors for blood transfusions in obstetrics and gynecology patients over one year. It included 115 women, with 110 obstetrics and 5 gynecology patients. Inclusion criteria covered women undergoing cesarean sections, vaginal deliveries, or other gynecological treatments and those with obstetric complications like postpartum hemorrhage. Exclusion criteria included women needing transfusions after seven days postpartum or with congenital bleeding disorders. Result: The majority of participants (66.96%) were aged 21-30, with 85.22% from low socioeconomic backgrounds. The mean BMI was 22.55±4.07. Most women (69.57%) were in the 31-40 weeks gestational age range. Multigravida and primigravida were 51.30% and 44.35%, respectively. Over half (57.6%) were not booked for antenatal care. Cesarean sections were the most common delivery method (60.87%). Vaginal delivery was the most frequent intervention (33.91%). Blood transfusion was mainly due to postpartum anemia (39.13%). Packed cell volume was the most transfused product (62.28%). Most (94.78%) had no transfusion reactions, with urticarial rash in 2.61% of cases. Conclusion: The study found that blood transfusions in obstetrics and gynecology are mainly due to severe anemia, postpartum hemorrhage, and complications like placenta previa and DIC. Most transfusions occurred in women aged 21-30, primarily multigravida and unbooked patients, indicating a need for better antenatal care. Packed cell volume was the most common blood product used.

Ancient documents play an important role in history. Various information regarding the literature, tradition and culture is kept in these documents. These heaps of documents are degraded because of some climatic circumstances, low quality and inappropriate holding. This paper reviews on the techniques used to retrieve the necessary content from these ancient documents. The techniques include preprocessing, image binarization, thresholding methods and post processing methods. Further, during scanning the document it can get corrupted with some unwanted lines or signals termed as noise that should be eliminated.

The demands of the twenty-first century have reshaped expectations for STEM education, highlighting the need for approaches that emphasize active participation, critical thinking, and interdisciplinary problem-solving. This paper examines the integration of active learning and inquiry-based science education (IBSE) as a strategy to enhance student engagement and achievement across STEM disciplines. Drawing exclusively from secondary sources published in 2021 or earlier, the study synthesizes theoretical foundations, instructional supports, and empirical outcomes associated with these pedagogies. The 5E instructional model and use of digital technologies are explored as effective frameworks for inquiry implementation, while formative assessment is presented as a tool for supporting student learning and reflection. Key enablers such as teacher professional development, curriculum alignment, and institutional support are discussed, along with evidence illustrating improvements in inquiry skills, especially in data interpretation and experimental design. The paper also highlights challenges, including limited progress in hypothesis formulation and systemic barriers to sustained implementation. Findings suggest that when active learning and inquiry-based approaches are embedded intentionally and supported adequately, they significantly enhance the quality and equity of STEM education. Recommendations are offered for expanding access to inquiry-rich instruction and fostering a culture of curiosity, reflection, and scientific reasoning in classrooms.

Diabetes mellitus is defined as a group of chronic metabolic diseases that are characterized by chronic hyperglycemia and other related metabolic disturbances. It is caused either by relative/absolute insulin deficiency or cellular resistance to insulin action, or both. Due to delay in the diagnosis process, and fear of the disease and its investigative procedure by some patients, diabetes mellitus has become the major cause of death. The most commonly employed investigative procedure to diagnose diabetes mellitus and controlling glycemia is blood investigation. Unfortunately, the procedure is invasive, painful, and may cause discomfort to patients due to the need for frequent testing. Consequently, a noninvasive, much simpler, and painless procedure is very desirable. Saliva represents an attractive alternative sample and offers a distinct advantage as it can be collected noninvasively and easily without special skill, and is low cost. The present review has found more studies with a positive correlation between blood and salivary glucose concentrations than those with a negative correlation. The difference between these studies' findings may be attributed to the difference in study population and criteria of selection, samples (saliva and blood) collecting methods, analyzing methods, and influencing factors that should be considered before the test.

Background: Upper lumbar disc herniation (ULDH), affecting the L1–L2 and L2–L3 levels, is relatively uncommon but often presents with atypical symptoms, making diagnosis and treatment challenging. Given its proximity to the conus medullaris and the narrower spinal canal in the upper lumbar region, even small disc herniations can produce significant neurological deficits. Aim: This study aimed to evaluate the clinical characteristics, surgical management, and outcomes of patients with ULDH treated at a tertiary care hospital in Bangladesh. Method: A retrospective review was conducted on 100 patients diagnosed with ULDH and treated surgically at a Tertiary Medical College Hospital in Bangladesh from January 2020 to December 2020. Patient data including demographics, presenting symptoms, radiological findings, surgical technique, and postoperative outcomes were analyzed. All patients underwent microdiscectomy or laminectomy based on clinical and radiological findings. Follow-up was conducted for six months postoperatively. Results: The mean age was 52.4 ± 11.6 years, with a male predominance (61%). Most patients presented with anterior thigh pain (78%), lower limb weakness (42%), and bladder dysfunction (12%). The most common disc level affected was L2–L3 (67%). Microdiscectomy yielded better recovery in patients with isolated disc herniation, while laminectomy was used for calcified or migrated discs. Significant improvement in VAS and ODI scores was noted postoperatively (p < 0.001). Only 5% of patients developed complications such as dural tear or superficial wound infection. Conclusion: ULDH, though rare, presents unique diagnostic and surgical challenges. Early surgical intervention tailored to the disc pathology results in favorable neurological and functional outcomes. Recognizing its atypical symptoms and imaging findings is crucial for timely and effective treatment.
