Oropharyngeal dysphagia, or difficulty in swallowing, is a major health problem that can lead to serious complications, such as pulmonary aspiration, malnutrition, dehydration, and pneumonia. The current clinical management of oropharyngeal dysphagia mainly focuses on compensatory strategies and swallowing exercises/maneuvers; however, studies have suggested their limited effectiveness for recovering swallowing physiology and for promoting neuroplasticity in swallowing-related neuronal networks. Several new and innovative strategies based on neurostimulation in peripheral and cortical swallowing-related regions have been investigated, and appear promising for the management of oropharyngeal dysphagia. The peripheral chemical neurostimulation strategy is one of the innovative strategies, and targets chemosensory ion channels expressed in peripheral swallowing-related regions. A considerable number of animal and human studies, including randomized clinical trials in patients with oropharyngeal dysphagia, have reported improvements in the efficacy, safety, and physiology of swallowing using this strategy. There is also evidence that neuroplasticity is promoted in swallowing-related neuronal networks with this strategy. The targeting of chemosensory ion channels in peripheral swallowing-related regions may therefore be a promising pharmacological treatment strategy for the management of oropharyngeal dysphagia. In this review, we focus on this strategy, including its possible neurophysiological and molecular mechanisms.

AbstractGlioma is the most common primary brain tumor, and is a major health problem throughout the world. Today, researchers have discovered many risk factors that are associated with the initiation and progression of gliomas. Studies have shown that PIWI-interacting RNAs (piRNAs) and PIWI proteins are involved in tumorigenesis by epigenetic mechanisms. Hence, it seems that piRNAs and PIWI proteins may be potential prognostic, diagnostic or therapeutic biomarkers in the treatment of glioma. Previous studies have demonstrated a relationship between piRNAs and PIWI proteins and some of the molecular and cellular pathways in glioma. Here, we summarize recent evidence and evaluate the molecular mechanisms by which piRNAs and PIWI proteins are involved in glioma.

Pulmonary tuberculosis is a major health problem in Bangladesh that is responsible for about 7% of total death in a year. This study was conducted to isolate and identify Mycobacterium tuberculosis from sputum and to evaluate the efficacy of PCR as a modern diagnostic tool, for diagnosis of pulmonary tuberculosis, especially in the smear negative cases. One hundred and fifty suspected pulmonary TB patients (male/ female: 97/53) were included in this study. Single morning sputum was collected from each patient and diagnostic potential of PCR was compared with staining and culture. Twenty five (16.7%) sputum were positive by ZN stained smear. Among 125 smear negative samples, 13 (10.4%) yielded growth in culture in LJ media and 21 (16.8%) samples were positive by PCR. The sensitivity and specificity of PCR in smear negative cases was 100% and 92.9% respectively. Mean detection time in PCR was 24 hours. PCR detected M. tuberculosis in 21 smear negative and 9 culture negative samples. For diagnosis of tuberculosis in smear negative cases, PCR directly from sputum was a very sensitive and accurate method. In conclusion, PCR may be done, especially in clinically suspected pulmonary tuberculosis patients who remain negative by conventional methods.DOI: http://dx.doi.org/10.3329/bjmm.v6i2.19368 Bangladesh J Med Microbiol 2012; 06(02): 2-6

Early Childhood Caries (ECC) is a chronic disease that can be prevented. It commonlyaffects children involving in one or more decayed (with lesions or not) teeth, missing teeth (dueto caries), or teeth with fillings in children aged under 71 months. The disease is sometimesoverlooked, but this condition usually affects the general health of children. Early detection ofEarly Childhood Caries (ECC) can prevent problems which are harmful to children. Therefore,the ECC must be prevented and for teeth that have had dental caries they should be givenproper treatment so as not to worsen and affect the quality of life in children. Prevention of thisdisease is a significant component in any health program to prepare for the optimal basis forthe oral health of children. This condition will become a serious health problem if not handledproperly, and it is a major health problem for health providers throughout the world.Primarypreventive must be initiated since a woman getting pregnant.Keywords: Early Childhood Caries (ECC), prevention, treatment

Viral hepatitis represents a major health problem worldwide. Approximately 1.4 million people are infected with hepatitis A virus every year, although given that most of the cases evolve asymptomatically the real number could be even higher. At the same time, hepatitis B virus affects up to 30% of the world population and represents one of the main causes of cirrhosis and hepatocellular carcinoma. Thus, it is very important to understand the physiopathology of viral hepatitis A and B not only for the diagnosis, but also for the therapeutic protocol. The present research aimed to determine if HAV and HBV can alter serum and salivary levels of total protein and of 2 important electrolytes: calcium and potassium.

Infectious diseases remain a major health problem and cause of death worldwide. It is expected that the socio-economic impact will further intensify due to escalating resistance to antibiotics, an ageing population and an increase in the number of patients under immunosuppressive therapy and implanted medical devices. Even though radiolabeled probes and leukocytes are routinely used in clinical practice, it might still be difficult to distinguish sterile inflammation from inflammation caused by bacteria. Moreover, the majority of these probes are based on the attraction of leukocytes which may be hampered in neutropenic patients. Novel approaches that can be implemented in clinical practice and allow for swift diagnosis of infection by targeting the microorganism directly, are posing an attractive strategy. Here we review the current strategies to directly image bacteria using radionuclides and we provide an overview of the preclinical efforts to develop and validate new approaches. Indeed, significant progress has been made in the past years, but very few radiopharmaceuticals (that were promising in preclinical studies) have made it into clinical practice. We will discuss the challenges that remain to select good candidates for imaging agents targeting bacteria.

: Insulin resistance and type 2 Diabetes mellitus resulting in chronic hyperglycemia is a major health problem in the modern world. Many drugs have been tested to control hyperglycemia which is believed to be the main factor behind many of the diabetes-related late-term complications. Wogonin is a famous herbal medicine which has been shown to be effective in controlling diabetes and its complications. In our previous work, we showed that wogonin is beneficial in many ways in controlling diabetic cardiomyopathy. In this review, we mainly explained wogonin anti-hyperglycemic property through AKT/GLUT4 pathway. Here we briefly discussed that wogonin increases Glut4 trafficking to plasma membrane which allows increased entry of glucose and thus alleviates hyperglycemia. Conclusion: Wogonin can be used as an anti-diabetic and anti-hyperglycemic drug and works via AKT/GLUT4 pathway.

Objective: Neuroinflammatory disease is a general term used to denote the progressive loss of neuronal function or structure. Many neuroinflammatory diseases, including Alzheimer’s, Parkinson’s, and multiple sclerosis (MS), occur due to neuroinflammation. Neuroinflammation increases nuclear factor-κB (NF-κB) levels, cyclooxygenase-2 enzymes and inducible nitric oxide synthase, resulting in the release of inflammatory cytokines, such as interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). It could also lead to cellular deterioration and symptoms of neuroinflammatory diseases. Recent studies have suggested that curcumin (the active ingredient in turmeric) could alleviate the process of neuroinflammatory disease. Thus, the present mini-review was conducted to summarize studies regarding cellular and molecular targets of curcumin relevant to neuroinflammatory disorders. Methods: A literature search strategy was conducted for all English-language literature. Studies that assessed the various properties of curcuminoids in respect of neuroinflammatory disorders were included in this review. Results: The studies have suggested that curcuminoids have significant anti- neuroinflammatory, antioxidant and neuroprotective properties that could attenuate the development and symptom of neuroinflammatory disorders. Curcumin can alleviate neurodegeneration and neuroinflammation through multiple mechanisms, by reducing inflammatory mediators (such as TNF-α, IL-1β, nitric oxide and NF-κB gene expression), and affect mitochondrial dynamics and even epigenetic changes. Conclusion: It is a promising subject of study in the prevention and management of the neuroinflammatory disease. However, controlled, randomized clinical trials are needed to fully evaluate its clinical potential.

Background : Self poisoning with organophosphate pesticides is a major health problem in world wide. Organophosphorus compound poisoning is a very common toxicological emergency encountered at Mirzapur in Tangail. It is particularly common among the rural agricultural worker's which comprise a substantial group of the population of this region.Objective: The objective of this study was to find out the incidence, frequency, pattern of poisoning, outcome and aetiological aspect of Organo phosphorus poisoning patient admitted in Kumudini Women's Medical college Hospital.Methods: A total 366 cases of OPC poisoning were analysed during 1 year from January 2015 to December 2015. The emphasis was given on age, sex, socio-economic status, occupation, motive of poisoning, types of compound consumed its quality, place, distance from referral place and the ultimate outcome.Results: Young population of rural background, particularly agricultural workers were the commonest patients (51.91%). The most common motive of poisoning was with a suicidal intent, both in males (27.59%) and females (66.39%). Financial crisis was one of the most common reasons analysed as the motive behind the poisoning (54.20%). Three hundred forty four Patients recovered and 22 were expired. The major cause of death in these cases was respiratory failure followed by multi-organ failure.Conclusion : Strict of the pesticide act and involving a new policy by the government to educate the public and youth in large about the dangerous, life threatening effects of Organophosphorus compound could help amelerioating the harmful effects of such poisoning.KYAMC Journal Vol. 9, No.-3, October 2018, Page 133-135
