Prevalence of quitting decision and the impact of increased cigarette prices on the smoking behaviours among the male garment workers in Bangladesh.

Objectives: The prevalence of tobacco use is high in Bangladesh, with a cigarette being the most consumed tobacco product. Taxing tobacco is highly effective for tobacco control, raising costs and encouraging smokers to quit or reduce cigarette consumption. Garment workers are the major group of low-wage earners in Bangladesh.

Association of HOTAIR rs7958904 Polymorphism with Cervical Cancer Risk.

Cervical cancer (CC) has been the prominent cause of cancer-associated fatalities among women in developing countries. In terms of occurrence and mortality, it is ranked second in Bangladesh. Although different genetic polymorphisms linked with this cancer have been investigated over time, the association between the HOTAIR rs7958904 variant and cervical cancer is being reported for the first time in Bangladeshi women.

Eating disorders among international migrants: a systematic review and meta-analysis.

Purpose: Migrants may have elevated exposure to stressors, which can affect their physical and mental well-being. However, migrants often experience a healthy immigrant effect, the applicability of this phenomena to eating disorders is unknown. We aimed to synthesize the available literature and estimate a summary measure of prevalence odds ratio for eating disorders in migrant populations compared to local populations.

Post-COVID-19 complications in home and hospital-based care: A study from Dhaka city, Bangladesh.

A cross-sectional survey was undertaken to understand the management patterns and post-COVID-19 complications among hospital and home-treated participants. Retrospective information was collected from four COVID-19 dedicated hospitals and four selected community settings. Using probability proportional sampling, 925 participants were selected.

Acoustomicrofluidic Concentration and Signal Enhancement of Fluorescent Nanodiamond Sensors.

Diamond nitrogen-vacancy (NV) centers constitute a promising class of quantum nanosensors owing to the unique magneto-optic properties associated with their spin states. The large surface area and photostability of diamond nanoparticles, together with their relatively low synthesis costs, make them a suitable platform for the detection of biologically relevant quantities such as paramagnetic ions and molecules in solution. Nevertheless, their sensing performance in solution is often hampered by poor signal-to-noise ratios and long acquisition times due to distribution inhomogeneities throughout the analyte sample.

Deterministic modeling of the diffusive memristor.

Recently developed diffusive memristors have gathered a large amount of research attention due to their unique property to exhibit a variety of spiking regimes reminiscent to that found in biological cells, which creates a great potential for their application in neuromorphic systems of artificial intelligence and unconventional computing. These devices are known to produce a huge range of interesting phenomena through the interplay of regular, chaotic, and stochastic behavior. However, the character of these interplays as well as the instabilities responsible for different dynamical regimes are still poorly studied because of the difficulties in analyzing the complex stochastic dynamics of the memristive devices.

Submicron Particle and Cell Concentration in a Closed Chamber Surface Acoustic Wave Microcentrifuge.

Preconcentrating particulate and cellular matter for their isolation or detection is often a necessary and critical sample preparation or purification step in many lab-on-a-chip diagnostic devices. While surface acoustic wave (SAW) microcentrifugation has been demonstrated as a powerful means to drive efficient particle concentration, this has primarily been limited to micron dimension particles. When the particle size is around 1 μm or below, studies on SAW microcentrifugation to date have shown that particle ring-like aggregates can only be obtained in contrast to the localized concentrated clusters that are obtained with larger particles.

Miniaturised acoustofluidic tactile haptic actuator.

Tactile haptic feedback is an important consideration in the design of advanced human-machine interfaces, particularly in an age of increasing reliance on automation and artificial intelligence. In this work, we show that the typical nanometer-order surface displacement amplitudes of piezoelectric transducers-which are too small to be detectable by the human touch, and constitute a significant constraint in their use for tactile haptic surface actuation-can be circumvented by coupling the vibration into a liquid to drive the deflection of a thermoplastic membrane. In particular, transmission of the sound energy from the standing wave vibration generated along a piezoelectric transducer into a microfluidic chamber atop which the membrane is attached is observed to amplify the mechanical vibration signalling through both the acoustic radiation pressure and the viscous normal stress acting on the membrane-the latter arising due to the acoustic streaming generated as the sound wave propagates through the liquid-to produce 100 μm-order static deflections of the membrane, upon which approximately 0.

Designing flexible energy and memory storage materials using cellulose modified graphene oxide nanocomposites.

The demand for flexible energy storage devices is ever increasing, and several polymer nanocomposites are widely used to fabricate them. Here, we present a cellulose based nanocomposite by incorporating graphene oxide (GO) nanoplatelets modified with hexamethylene diisocyanate grafting agent useful for such versatile applications. The simple method of casting/solvent evaporation is applied to prepare the nanocomposites and GO dispersion in the cellulose matrix was analyzed by Fourier transform infrared spectroscopy, X-ray diffraction studies and scanning electron microscopy.

Melphalan plus prednisolone in the treatment of multiple myeloma.

Various chemotherapies are used for better remission of symptoms of multiple myeloma as it is not a curable disease. This study was carried out to evaluate the response of melphalan plus prednisolone therapy for the treatment of Multiple myeloma. The study was conducted in the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from January to December 2009.

Fluctuation of pain by weather change in musculoskeletal disorders.

In order to find out the fluctuation of pain by weather change, a descriptive cross-sectional study was conducted among 138 individuals having musculoskeletal disorders (MSDs) attending the out patient department (OPD) of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital, Dhaka, during March 2004 to June 2004. Data were collected by face to face interview employing a pre-tested interview schedule containing structured questions. Among 138 respondents, male were predominant (52.

Gestational anemia.

Gestational anemia is a common public health problem in our country. Most anemia during pregnancy results from an increased need for iron as her body is making more blood. Often dietary supplementation does not provide enough iron to meet the extra needs.

Angiogenesis-a novel therapeutic approach for ischemic heart disease.

Angiogenesis is the biologic process of forming new blood vessels. Undoubtedly, blood vessels growth regulation is a vital aspect in health and disease. Under physiological conditions, angiogenesis is regulated by local balance between endogenous stimulators and inhibitors of this process.

Is affluent society aware of their health status?

Our study was done on 111 participants of different government institutions who were involved in the highest most responsibilities in their respective jobs. Their higher educational level, job stress, type1 personality affect a lot on their health status. Therefore, it was our concern to investigate the various health risk factors and their impacts on the health status of this study group.

Iodized salt induced thyrotoxicosis: Bangladesh perspective.

The effects of iodized and non-iodized salt on the thyroid gland and its hormones T3, T4 and thyroid stimulating hormone (TSH) were studied in 200 individuals who were the residents of plain areas of greater Mymensingh district.
