The world's low-lying rice (Oryza sativa) cultivation areas are under threat of submergence or flash flooding due to global warming. Rice plants manifest a variety of physiological and morphological changes to cope with submergence and hypoxia, including lowering carbohydrate consumption, inhibiting shoot elongation, and forming a thicker leaf gas film during submergence. Functional studies have revealed that submergence tolerance in rice is mainly determined by an ethylene response factor (ERF) transcription factor-encoding gene, namely SUBMERGENCE 1A-1 (SUB1A-1) located in the SUB1 quantitative trait locus.

Objective: Colorectal cancer (CRC) is the most preventable cancer if adherence to its screening guidelines through compliance with physician recommendations are met. Lack of access to care is the most significant barrier which was decreased by the Affordable Care Act (ACA), that may influence healthcare behaviors/practices. The aim of this study was to determine the factors affecting compliance with recommendations for CRC screening between two US National Health Interview Surveys (NHIS) in 2010 and 2015.

Long-term, often lifelong care for cardiovascular disease (CVD) patients requires consistent use of medicine; hence, the availability of essential medicine for CVD (EM-CVD) is vital for treatment, quality of life, and survival. We aimed to assess the availability of EM-CVD and explore healthcare facility (HCF) characteristics associated with the availability of those medicines in Bangladesh. This study utilized publicly available cross-sectional data from the 2014 and 2017 waves of the Bangladesh Health Facilities Survey (BHFS).

Introduction Despite significant advances in the field of medicine, sepsis is constantly growing as a major public health concern. The global epidemic of sepsis imposes a significant economic burden on healthcare systems world-over. Furthermore, its high prevalence in society is inevitably paralleled by an excessive mortality rate, with approximately six million deaths reported every year.

A simple process based on the dual roles of both magnesium oxide (MgO) and iron oxide (FeO) with boron (B) as precursors and catalysts has been developed for the synthesis of borate composites of magnesium and iron (MgBO-FeBO) at 1200°C. The as-synthesized composites can be a single material with the improved and collective properties of both iron borates (FeBO) and magnesium borates (MgBO). At higher temperatures, the synthesized MgBO-FeBO composite is found thermally more stable than the single borates of both magnesium and iron.

The coronavirus disease 2019 (COVID-19) pandemic has had a devastating and disproportionate impact on the elderly population. As the virus has swept through the world, already vulnerable elderly populations worldwide have faced a far greater burden of deaths and severe disease, crippling isolation, widespread societal stigma, and wide-ranging practical difficulties in maintaining access to basic health care and social services - all of which have had significant detrimental effects on their mental and physical wellbeing. In this paper, we present an overview of aging and COVID-19 from the interrelated perspectives of underlying biological mechanisms, physical manifestations, societal aspects, and health services related to the excess risk observed among the elderly population.

Objective: The primary objectives were to determine the magnitude of COVID-19 infections in the general population and age-specific cumulative incidence, as determined by seropositivity and clinical symptoms of COVID-19, and to determine the magnitude of asymptomatic or subclinical infections.

Design, Setting And Participants: We describe a population-based, cross-sectional, age-stratified seroepidemiological study conducted throughout Afghanistan during June/July 2020. Participants were interviewed to complete a questionnaire, and rapid diagnostic tests were used to test for SARS-CoV-2 antibodies.

Silicon (Si) application has great potential to improve salt tolerance in a variety of crop plants. However, it is unclear how Si influences the responses of contrasting rice cultivars when exposed to excessive salt. Here, we investigated the functions of Si in alleviating the negative effects of salt stress on two contrasting rice cultivars, namely BRRI dhan48 (salt-sensitive) and Binadhan-10 (salt-tolerant).

Background: Bangladesh ranks among the world's top ten countries in the number of diabetic patients. The prevention of this disease requires treating patients with essential medicines, and the first crucial step in the uptake of these medicines is availability. We aimed to assess the availability of essential medicines for diabetes (EM-Diabetes) and to explore health facility characteristics associated with the availability of those medicines.

This article presents the results of a study conducted to measure the gross alpha, gross beta activities in medicinal plant samples collected from different districts of Azad Kashmir, Pakistan. The ASC-950-DP gasless high-speed counter was used for the measurement of gross / activities. Measured activities have been used to assess age-dependent annual effective doses for infants, one-, five-, ten-, and fifteen-year-old and adult people.

With many advantages over well-established methods, laser induced breakdown spectroscopy (LIBS) has emerged as a useful analytical technique for the compositional analysis of multi-elemental geological materials. In this study, LIBS was employed for qualitative and quantitative analysis of a rare mineral, astrophyllite, bearing precious elements of industrial and technological interest. The experiment was carried out using second harmonic generation of Nd:YAG laser of pulse width 5 ns and repetition rate of 10 Hz.

While the effectiveness of lockdowns to reduce Coronavirus Disease-2019 (COVID-19) transmission is well established, uncertainties remain on the lifting principles of these restrictive interventions. World Health Organization recommends case positive rate of 5% or lower as a threshold for safe reopening. However, inadequate testing capacity limits the applicability of this recommendation, especially in the low-income and middle-income countries (LMICs).

The COVID-19 pandemic has laid bare the devastating truth about pervasive health inequity in the United States. As the virus swept through the country, underserved racial and ethnic minority populations disproportionately bore the brunt of the hospitalizations, severe illness, and fatalities. The devastation among these groups far outstripped their privileged counterparts due to convergence of disadvantages that created a perfect storm of exposures.

Introduction: The rate of cesarean delivery (C-section) has been increasing worldwide, including Bangladesh, and it has a negative impact on the mother and child's health. Our aim was to examine the association between C-section and childhood diseases and to identify the key factors associated with childhood diseases.

Methods: We used four nationally representative data sets from multiple indicator cluster survey (MICS, 2012 and 2019) and Bangladesh Demographic and Health Survey (BDHS, 2011and 2014) and analyzed 25,270 mother-child pairs.

Article Synopsis
  • A study evaluated the knowledge of cervical cancer among 141 female college students and its impact on adherence to Pap smear guidelines, revealing that many lacked awareness and regular checkups.
  • Results showed that a significant percentage (69%) never had a Pap test, often citing procrastination, fear, and lack of interest, and most were unaware of free testing options available through university health services.
  • Higher knowledge about cervical cancer risk factors, particularly related to sexual activity, was linked to increased likelihood of receiving Pap tests; thus, improving knowledge can lead to better adherence to screening recommendations.

Qualitative and quantitative analysis of the raw granite rocks acquired from deposits in the Hunza district, Gilgit area of Pakistan were studied using laser-induced breakdown spectroscopy (LIBS) and laser ablation time-of-flight mass spectrometry (LA-TOF-MS). The optical emission spectra of the granite rocks used in artificial jewelry and for flooring tiles show the emission lines of (Si, Ca, K, Fe, Mg, Al, Na, and Li) and (Si, Ca, K, Fe, Mg, Al, Ti, Na, Ba, and Li), respectively. The mass spectra of these granite rocks were also studied with the LA-TOF-MS, revealing analogous elemental compositions.
