Introduction: The COVID-19 pandemic has challenged healthcare facilities and healthcare professionals' stamina and wellbeing. This study examines the psychological impact of COVID-19 on healthcare professionals., Methods: This analytical cross-sectional study was conducted in July 2020 after institutional review board approval at a tertiary care institution in Lahore, Pakistan. A total of 175 healthcare workers participated following an online Depression, Anxiety and Stress Scale-21 (DASS-21) questionnaire invitation and 41 were excluded following pre-existing mental health conditions. Data was analysed using MS Excel and SPSS Amos 23. Chi-squared test and regression were applied for comparison and impact of confounding variables respectively (p<0.05 was considered significant)., Results: Out of 134, 66 (49%) were doctors, 24 (18%) were nurses and 44 (33%) were non-medical professionals. Ninety-five (70%) with age 21-30 years. Male to female ratio was 2:1. Overall mean depression score accounted for 6.89 ± 6.64; anxiety score was 7.28 ± 6.74 and stress score was 8.83 ± 6.93. Mild depression, anxiety and stress was noted in 21 (15.6%), eight (6%) and 27 (20.1%) healthcare workers, respectively. A statistically significant difference (p<0.05) was observed among healthcare workers for depression, anxiety and stress., Conclusion: This study demonstrated considerable impact of COVID-19 on mental health of healthcare workers. A well-structured targeted mental health support programme is needed urgently to support and reduce the long-term impact on healthcare workers' mental health and wellbeing., (© Royal College of Physicians 2021.

Objective: This prospective, pilot randomized double-blind study aimed to compare the effects of buffered and non-buffered xylocaine solutions on injection pain and anesthesia effectiveness in patients undergoing arteriovenous fistula surgery., Material and Methods: A total of 100 adult patients meeting inclusion criteria undergoing arteriovenous fistula surgery were included in the study. They were split into two groups at random. The control group received 1% xylocaine dissolved in 5 ml distilled water, while the intervention group received sodium bicarbonate mixed with 1% xylocaine solution as a local anesthetic. The patients were asked to rate the pain of first and subsequent injections on a visual analog scale (VAS). Besides, the need for extra analgesia was investigated. The mean and standard deviation of the data was determined., Results: During both the first and subsequent injections, the alkalinized local anesthetic group showed substantially lower VAS scores. In the alkalinized local anesthetic group, anesthesia satisfaction was also more than three times higher. Furthermore, the non-alkalinized group's mean analgesic requirement was higher than the intervention group., Conclusion: Our findings support the effectiveness of the alkalinized local anesthetic solution in minimizing injection pain and increasing anesthesia duration and overall patient's surgical experience in terms of anesthesia satisfaction score., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Arif et al.)

Introduction: The objective of our study was to explore the views and perceptions of female patients attending the obstetrics and gynecology (OB/GYN) outpatient department towards the gender of their healthcare provider, to look for any preference that might exist in this regard, and to highlight any discrimination towards male obstetricians/gynecologists., Material and Methods: A cross-sectional study was conducted from November 2020 to March 2021 at Combined Military Hospital, Lahore. A total of 280 female patients were included in the study and interviewed consecutively. A self-designed questionnaire was administered. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 22 (IBM Corp., Armonk, NY). Chi-square test was used to determine for any statistical significance and p≤0.05 was considered significant. Numerical data were represented as percentages., Results: Over 280 female patients participated in our study, out of which 132 were married and 148 were single. Thirteen of these patients were uneducated, 40 had completed high school and 227 patients had obtained a bachelor's level of education; 120 patients were aged 15-25 years, 95 patients were aged 26-35 years, 30 patients were aged 36-45 years, and 35 patients were aged >46. Women with less education preferred to be seen by a female obstetrician/gynecologist, whereas those with higher education were less biased (p=0.0001). Married patients preferred to be seen by female obstetrician/gynecologists as compared to single patients (p=0.0004). A significant proportion of females were impartial in terms of physician competence but those who did have a preference preferred female obstetrician/gynecologist based on three significant variables: competence, rapport building and empathy, and personal comfort., Conclusion: A female gender preference exists in obstetrics and gynecology clinic attendees. This is significant in those who are married and those with no formal education. Overall, a significant proportion of women feel a higher comfort level with female doctors and find it easier to discuss their medical issues and develop rapport., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Riaz et al.)

Objective Tachycardia is a potential side effect of salbutamol inhalation. We aimed to study the short-term effect of salbutamol nebulization on the heart rate of healthy volunteers. Material and methods A randomized, single-blinded, placebo-controlled, cross-over study was conducted with 30 healthy volunteers divided into two groups of 15 each. One group was nebulized with salbutamol (2.5 mg/2 ml dilution) while the other group was given normal saline (2 ml). Each arm underwent administration of the opposite drug the following week. Baseline readings of heart rate and blood pressure were taken at zero (T0), seven (T7), 15 (T15), and 30 (T30) minutes. Results Thirty volunteers between the ages of 20 and 25 years were studied. The mean heart rate value was higher for nebulized salbutamol at each point as compared to saline. When nebulized with salbutamol, the heart rate had a significant rise (p= < 0.00001) at 15 minutes as compared to saline nebulization. Conclusion Salbutamol nebulization, even at a low dose, can lead to a significant increase in heart rate when compared to nebulization with normal saline in healthy individuals., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Syed et al.)

Introduction Coronavirus disease 2019 (COVID-19) presents with a wide spectrum of symptoms, ranging from patients being asymptomatic to having life-threatening acute respiratory distress syndrome (ARDS). COVID-19 emerged as a pandemic and has led to multiple causalities worldwide. A better understanding of the clinical characteristics of the COVID-19 patients and their disease course will aid in better management of these patients and hence may positively impact their outcomes as well. Methodology This was a retrospective observational study conducted from   April 15, 2020, to   August 31, 2020, after gaining institutional review board approval at the University of Lahore Teaching Hospital, Lahore, Pakistan. A total of 47 patients with severe disease who had died due to COVID-19 during this period were enrolled by the consecutive method. Patients were evaluated for their epidemiological, biochemical, clinical, and radiological features. The modified Radiographic Assessment of Lung Edema (mRALE) score was used to calculate the extent of alveolar opacities and percentages of lung involvement in chest radiographs. Furthermore, patients' management plans were also evaluated. Data were analyzed using SPSS Statistics version 23 (IBM, Armonk, NY). Results The mean age of the patients was 61.53 ±13.35 years. The male-to-female ratio was 2:1, and the mean BMI was 28.05 ±3.52 kg/m 2 . Diabetes was the most prevalent comorbidity among the patients (32, 68.1%), followed by hypertension (six, 12.8%), ischemic heart disease (five, 10.6%), and chronic kidney disease (four, 8.5%) respectively. The predominant symptom observed among patients was cough (95%), followed by shortness of breath (93%), fever (63%), sputum (23%), and gastrointestinal symptoms (6.4%). The mean D-dimer was 1,567.13 ±1,903.77 ng/mL, mean ferritin was 1,730.34 ±1,382.35 ng/mL, mean C-reactive protein (CRP) was 202.59 ±104.97 mg/dl, and the mean neutrophil-to-lymphocyte ratio was 10.50 ±9.58. Bilateral lung involvement was seen among 40 (85.11%) patients whereas unilateral right lung involvement was reported in three (6.38%) and unilateral left lung involvement in four (8.51%) respectively. The mean mRALE score for bilateral lung involvement was 18.78 ±4.89. The mean area radiologically involved in bilateral lung fields was 72.12 ±18.45%, followed by unilateral right lung involvement of 67.87 ±15.97%, and unilateral left lung involvement of 61.38 ±17.95% in the cohort respectively. The most common type of radiological pathology was diffuse ground-glass opacities, which was observed in 18 (38%) patients. Most patients received antibiotics (39, 63.83%), while nine (19%) received tocilizumab, four (8.5%) had antiviral therapy, and three (6.4%) were given plasma treatment. All patients received glucocorticoids and anticoagulation. The most common cause of death was ARDS, which was observed in 12 (25.5%) patients. Conclusion This study significantly demonstrated that most cases were males above 50 years of age with chronic medical comorbidities of diabetes, hypertension, and ischemic heart disease. COVID-19 has a predilection for multisystem involvement leading to mortality. In addition, elevated D-dimer and neutrophil-to-lymphocyte ratio may be indicative of a poor prognosis. A combination of antimicrobials had no positive impact on the outcomes in this cohort. It is difficult to predict the efficacy of tocilizumab and remdesivir as only a few patients in the cohort received these drugs., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Ussaid et al.)

Introduction: Osteoarthritis (OA) is a degenerative disease of joints which if untreated can lead to a permanent disability of joints. Obesity plays an important role in the morbidity of OA. Since there is no curative treatment for OA, several researches focusing on nonpharmacological intervention for OA have come forth. Triad of education, exercise, and weight loss has been gaining popularity as a first-line nonpharmacological treatment for OA. This article measures the number of OA patients, irrespective of age and gender, who have received weight-loss counseling from their physicians and it also studies patients' willingness to lose weight after being counseled., Methodology: A cross-sectional study was conducted from 10th June 2020 to 10th July 2020. Diagnosed cases of OA were included and their consent was taken. A self-administered questionnaire was used which included questions asking if they have ever received weight-loss counseling and if they will try to lose weight on being advised by their physician. Data were collected from the participants using google forms and analyzed using SPSS-22., Results: Out of 199 OA patients included in our study, only 28 (14%) participants received weight loss and exercise counseling from their physicians. A positive response was observed in 175 (87.9%) participants out of 199 who reported that they would exercise and practice a healthy lifestyle to lose weight if they were advised properly., Conclusion: Results of our study showed that the total number of OA patients receiving advice from their treating physician regarding weight loss is less. However, the majority of the patients were willing to exercise and control their weight if advised properly by their physician., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Inam et al.)

Magnetoencephalography (MEG) has a unique capacity to resolve the spatio-temporal development of brain activity from non-invasive measurements. Conventional MEG, however, relies on sensors that sample from a distance (20-40 ​mm) to the head due to thermal insulation requirements (the MEG sensors function at 4 ​K in a helmet). A gain in signal strength and spatial resolution may be achieved if sensors are moved closer to the head. Here, we report a study comparing measurements from a seven-channel on-scalp SQUID MEG system to those from a conventional (in-helmet) SQUID MEG system. We compared the spatio-temporal resolution between on-scalp and conventional MEG by comparing the discrimination accuracy for neural activity patterns resulting from stimulating five different phalanges of the right hand. Because of proximity and sensor density differences between on-scalp and conventional MEG, we hypothesized that on-scalp MEG would allow for a more high-resolved assessment of these activity patterns, and therefore also a better classification performance in discriminating between neural activations from the different phalanges. We observed that on-scalp MEG provided better classification performance during an early post-stimulus period (10-20 ​ms). This corresponded to the electroencephalographic (EEG) component P16/N16 and was an unexpected observation as this component is usually not observed in conventional MEG. This finding shows that on-scalp MEG enables a richer registration of the cortical signal, indicating a sensitivity to what are potentially sources in the thalamo-cortical radiation. We had originally expected that on-scalp MEG would provide better classification accuracy based on activity in proximity to the P60m component compared to conventional MEG. This component indeed allowed for the best classification performance for both MEG systems (60-75%, chance 50%). However, we did not find that on-scalp MEG allowed for better classification than conventional MEG at this latency. We suggest that this absence of differences is due to the limited sensor coverage in the recording, in combination with our strategy for positioning the on-scalp MEG sensors. We show how the current sensor coverage may have limited our chances to register the necessary between-phalange source field dissimilarities for fair hypothesis testing, an approach we otherwise believe to be useful for future benchmarking measurements., (Copyright © 2020 The Authors.

Maize ZmC1 and ZmR transcription factors belong to the MYB-type and bHLH families, respectively, and control anthocyanin biosynthesis. In this study, Agrobacterium -mediated transformation was used to generate transgenic wheat plants that overexpress ZmC1 and ZmR or both, with the objective of developing anthocyanin-enriched wheat germplasm. Three kinds of stable transgenic wheat lines were obtained. The integration of target genes in the transgenic wheat plants was confirmed by fluorescence in situ hybridization (FISH) analysis. We found that single overexpression of ZmC1 regulates pigmentation in the vegetative tissues such as coleoptiles, auricles, and stems. The single overexpression of ZmR controls the coloration in reproductive tissue like spikelets and seeds. The simultaneous overexpression of ZmC1 and ZmR showed the strongest pigmentation in almost all tissues. Furthermore, quantitative real-time PCR (qRT-PCR) analysis revealed that expression of the two transgenes, and of two conserved homologous and six associated structural genes involved in anthocyanin biosynthesis in wheat were greatly up-regulated in the transgenic plants. Similarly, quantitative analysis for anthocyanin amounts based on HPLC-MS also confirmed that the transgenic wheat plants with combined overexpression of ZmC1 and ZmR accumulated the highest quantity of pigment products. Moreover, developing seeds overexpressing ZmR exposed to light conditions showed up-regulated transcript levels of anthocyanin biosynthesis-related genes compared to dark exposure, which suggests an important role of light in regulating anthocyanin biosynthesis. This study provides a foundation for breeding wheat materials with high anthocyanin accumulation and understanding the mechanism of anthocyanin biosynthesis in wheat.

Folates are essential micronutrients in the human diet. Germplasm rich in folates can be used as genetic resource for diet and breeding to produce new varieties with enhanced folates. To investigate the natural variation of folates among wheat cultivars and identify high folate materials for breeding, we studied the grain folate contents of 360 wheat samples consisting of 315 wheat genotypes grown in North China using the high performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS) method. The total folate content among wheat genotypes ranged from 10.15 ± 2.86 to 91.44 ± 5.64 µg per 100 g grains, thus showing a remarked variation. Fifty-two wheat cultivars, such as Henong58-3, were identified as good sources of folates. 5-Formyltetrahydrate and 5-methyltetrahydrate were found to be the two major folate derivatives in wheat germplasm. In addition, we found that environment factor also had significant effect on folate production. This investigation can help wheat breeders for folate improvement., (Copyright © 2019 Elsevier Ltd.

Gamma oscillations facilitate information processing by shaping the excitatory input/output of neuronal populations. Recent studies in humans and nonhuman primates have shown that strong excitatory drive to the visual cortex leads to suppression of induced gamma oscillations, which may reflect inhibitory-based gain control of network excitation. The efficiency of the gain control measured through gamma oscillations may in turn affect sensory sensitivity in everyday life. To test this prediction, we assessed the link between self-reported sensitivity and changes in magneto-encephalographic gamma oscillations as a function of motion velocity of high-contrast visual gratings. The induced gamma oscillations increased in frequency and decreased in power with increasing stimulation intensity. As expected, weaker suppression of the gamma response correlated with sensory hypersensitivity. Robustness of this result was confirmed by its replication in the two samples: neurotypical subjects and people with autism, who had generally elevated sensory sensitivity. We conclude that intensity-related suppression of gamma response is a promising biomarker of homeostatic control of the excitation-inhibition balance in the visual cortex., (© 2018 Wiley Periodicals, Inc.)

Folates are indispensable co-factors for one-carbon metabolism in all organisms. In humans, suboptimal folate intake results in serious disorders. One promising strategy for improving human folate status is to enhance folate levels in food crops by metabolic engineering. In this study, we cloned two GmGCHI (GTP cyclohydrolase I) genes (Gm8gGCHI and Gm3gGCHI) and one GmADCS (aminodeoxychorismate synthase) gene from soybean, which are responsible for synthesizing the folate precursors pterin and p-aminobenzoate, respectively. We initially confirmed their functions in transgenic Arabidopsis plants and found that Gm8gGCHI increased pterin and folate production more than Gm3gGCHI did. We then co-expressed Gm8gGCHI and GmADCS driven by endosperm-specific promoters in maize and wheat, two major staple crops, to boost their folate metabolic flux. A 4.2-fold and 2.3-fold increase in folate levels were observed in transgenic maize and wheat grains, respectively. To optimize wheat folate enhancement, codon-optimized Gm8gGCHI and tomato LeADCS genes under the control of a wheat endosperm-specific glutenin promoter (1Dx5) were co-transformed. This yielded a 5.6-fold increase in folate in transgenic wheat grains (Gm8gGCHI+/LeADCS+). This two-gene co-expression strategy therefore has the potential to greatly enhance folate levels in maize and wheat, thus improving their nutritional value., (© The Author(s) 2019.

Plant tolerance to biotic and abiotic stresses is complicated by interactions between different stresses. Maintaining crop yield under abiotic stresses is the most daunting challenge for breeding resilient crop varieties. In response to environmental stresses, plants produce several metabolites, such as proline (Pro), polyamines (PAs), asparagine, serine, carbohydrates including glucose and fructose, and pools of antioxidant reactive oxygen species. Among these metabolites, Pro has long been known to accumulate in cells and to be closely related to drought, salt, and pathogen resistance. Pyrroline-5-carboxylate (P5C) is a common intermediate of Pro synthesis and metabolism that is produced by ornithine aminotransferase (OAT), an enzyme that functions in an alternative Pro metabolic pathway in the mitochondria under stress conditions. OAT is highly conserved and, to date, has been found in all prokaryotic and eukaryotic organisms. In addition, ornithine (Orn) and arginine (Arg) are both precursors of PAs, which confer plant resistance to drought and salt stresses. OAT is localized in the cytosol in prokaryotes and fungi, while OAT is localized in the mitochondria in higher plants. We have comprehensively reviewed the research on Orn, Arg, and Pro metabolism in plants, as all these compounds allow plants to tolerate different kinds of stresses.

Gamma-band oscillations arise from the interplay between neural excitation (E) and inhibition (I) and may provide a non-invasive window into the state of cortical circuitry. A bell-shaped modulation of gamma response power by increasing the intensity of sensory input was observed in animals and is thought to reflect neural gain control. Here we sought to find a similar input-output relationship in humans with MEG via modulating the intensity of a visual stimulation by changing the velocity/temporal-frequency of visual motion. In the first experiment, adult participants observed static and moving gratings. The frequency of the MEG gamma response monotonically increased with motion velocity whereas power followed a bell-shape. In the second experiment, on a large group of children and adults, we found that despite drastic developmental changes in frequency and power of gamma oscillations, the relative suppression at high motion velocities was scaled to the same range of values across the life-span. In light of animal and modeling studies, the modulation of gamma power and frequency at high stimulation intensities characterizes the capacity of inhibitory neurons to counterbalance increasing excitation in visual networks. Gamma suppression may thus provide a non-invasive measure of inhibitory-based gain control in the healthy and diseased brain.

Drosophila melanogaster being used as model organism is considered as pest of homes, restaurants, and fruit markets. The damaged fruits are also reported to serve as a carrier for various diseases. The current study was designed to evaluate the toxicity of petroleum extract of some weed plants, namely, Euphorbia prostrata , Parthenium hysterophorus , Fumaria indica , Chenopodium murale , and Azadirachta indica, against D . melanogaster . Mortality at 10, 20, and 30% concentrations after 24 and 48 hours was found comparatively low. E. prostrata caused high mortality (51.64%) at 30% concentration and was found more toxic (LC 50 27.76; P value 0.00) after 72 hours. A. indica showed high LC 50 value ( P value 0.15) compared to other weed plants. The combination of E. prostrata and Bti showed highest mortality (100%; LC 50 12.49; P value 0.00) after 72 hours. Similarly, the same combination caused maximum reduction in the activity of AChE, AcP, AkP, α -Carboxyl, and β -Carboxyl enzymes. Phytochemical analysis showed the presence of flavonoids, saponins, tannins, steroids, cardiac glycosides, alkaloids, anthraquinones, and terpenoids. FTIR analysis of E. prostrata showed the presence of phenolic compounds. It is suggested that further studies are needed in order to incorporate weed plant extracts in combination with Bti for the management of fruit flies.

Chikungunya viruses from the 2017 outbreak in Dhaka, Bangladesh, were analysed phylogenetically. E1 sequences from 21 strains belonged to the Indian Ocean clade of the East/Central/South African (ECSA) genotype, forming a novel cluster with latest South Asian strains. They lacked the A226V substitution.

Parkinsonism is characterized by rest tremor, inflexibility, balance debilitation, slow motion and dementia. It is known to be caused by the deficiency of dopaminergic neurons in nigrostriatal pathway. Different studies propose that oxidative burden may be included in the apoptotic process in parkisnons disease. Zamzam water being alkaline in composition may diminish the oxidative stress and hence relieve the symptoms. Therefore, the purpose of this study was to explore the neuroprotective effect of zamzam water in chlorpromazine induced animal model of Parkinsonism. Results revealed that zamzam water did not show significant anticataleptic effect after 21 days as compared to chlorpromazine treated group. However, after 30 days of giving zamzam water showed highly significant decrease (p<0.001) in cataleptic score as compared to chlorpromazine treated group that is negative control. After 30 days of dosing, cataleptic scores by zamzam water were closer to standard drug but standard drug (levodopa/carbidopa) still showed better results than zamzam water. Results from histopathological study of rat's brain also revealed regenerative changes by zamzam treated water when compared with negative control. This regenerative change after zamzam water treatment might play a positive role in future if administered continuously. These results also suggest that zamzam water can be used in combination with standard drug to produce synergistic effect in the management of parkinsons disease.

While commercial magnetoencephalography (MEG) systems are the functional neuroimaging state-of-the-art in terms of spatio-temporal resolution, MEG sensors have not changed significantly since the 1990s. Interest in newer sensors that operate at less extreme temperatures, e.g., high critical temperature (high-T c ) SQUIDs, optically-pumped magnetometers, etc., is growing because they enable significant reductions in head-to-sensor standoff (on-scalp MEG). Various metrics quantify the advantages of on-scalp MEG, but a single straightforward one is lacking. Previous works have furthermore been limited to arbitrary and/or unrealistic sensor layouts. We introduce spatial information density (SID) maps for quantitative and qualitative evaluations of sensor arrays. SID-maps present the spatial distribution of information a sensor array extracts from a source space while accounting for relevant source and sensor parameters. We use it in a systematic comparison of three practical on-scalp MEG sensor array layouts (based on high-T c SQUIDs) and the standard Elekta Neuromag TRIUX magnetometer array. Results strengthen the case for on-scalp and specifically high-T c SQUID-based MEG while providing a path for the practical design of future MEG systems. SID-maps are furthermore general to arbitrary magnetic sensor technologies and source spaces and can thus be used for design and evaluation of sensor arrays for magnetocardiography, magnetic particle imaging, etc.

Objective: We present a benchmarking protocol for quantitatively comparing emerging on-scalp magnetoencephalography (MEG) sensor technologies to their counterparts in state-of-the-art MEG systems., Methods: As a means of validation, we compare a high-critical-temperature superconducting quantum interference device (high T c SQUID) with the low- T c SQUIDs of an Elekta Neuromag TRIUX system in MEG recordings of auditory and somatosensory evoked fields (SEFs) on one human subject., Results: We measure the expected signal gain for the auditory-evoked fields (deeper sources) and notice some unfamiliar features in the on-scalp sensor-based recordings of SEFs (shallower sources)., Conclusion: The experimental results serve as a proof of principle for the benchmarking protocol. This approach is straightforward, general to various on-scalp MEG sensors, and convenient to use on human subjects. The unexpected features in the SEFs suggest on-scalp MEG sensors may reveal information about neuromagnetic sources that is otherwise difficult to extract from state-of-the-art MEG recordings., Significance: As the first systematically established on-scalp MEG benchmarking protocol, magnetic sensor developers can employ this method to prove the utility of their technology in MEG recordings. Further exploration of the SEFs with on-scalp MEG sensors may reveal unique information about their sources.

Present study was designed to demonstrate the effect ethanolic leaf extract of Thuja orientalis on the learning and memory formation in albino mice. Four week old albino mice were either orally supplemented with 50mg/ml solvent/Kg body weight of Thuja orientalis or with equal volume of saline solution (0.9% NaCl) for seven days. A battery of neurological tests (Elevated plus maze, Rota Rod, light and dark box, open field and novel object recognition test) were applied at the end of dose supplementation. Thuja orientalis leaf extract treated female mice spent significantly les time on rotating rod (P = 0.02) than male treated with saline solution [indicating poor neuromuscular coordination]. While all other neurological test performances varied non significantly (P > 0.05) when compared between Thuja orientalis treated albino mice (of both genders) with their respective control groups indicating a moderate effect of 50mg/ml solvent/Kg body weight of Thuja orientalis on the behavior of young albino mice.

The risk factor profiles, management and outcome have significant difference between stroke subsets. Aim of this study was to investigate the risk for the two most common subtypes of stroke in Bangladeshi population. Seventy cases of hemorrhagic stroke (HS) and 105 cases of confirmed ischemic stroke (IS) were recruited from the Shaheed Suhrawardy Medical College Hospital (ShSMCH) and Dhaka Medical College Hospital between January-June 2011. Total 171 age, sex matched controls were selected from the hospitalized patients with history of no stroke ever. Average hemorrhagic stroke patients (60.4 ± 12.3 years) were younger than both ischemic strokes (63.5 ± 13 years). Family history of premature cardiovascular death was found more in HS patients (p = 0.001). Multivariate logistic regression showed, in IS model 'less fruit consumption (OR 4.6), table salt intake (OR 8.15), psychosocial stress (OR 3.5), abnormal ECG (OR 3.6) and Increased WHR (OR 6.9) appeared as significant predictors adjusted for all potential candidate confounders. In HS model less fruit consumption (OR 5.0), table salt intake (OR 9.9), Stress (OR 4.1), family history of cardiovascular disease (CVD) death (OR 11.3), hypertension (OR 43), aspirin intake (OR 4.5) and increased WHR (OR 3.7) remained as significant predictors.

Cholesterol is believed to be the major regulator involved in the formation and progression of atheroma plaque. Seaweeds are known to possess enormous biological activities. They contain variety of active constituents, which have pharmacological significance. The objective of this study is to explore hypolipidemic and hepatoprotective activities of the brown seaweed Iyengariastellata. Ethanolic extract of seaweed was suspended in distilled water and administered orally at 10mg/200g body weight to rabbits for 30 days and total lipid level, cholesterol, triglycerides, HDL, LDL, VLDL, alkaline phosphatase, SGPT, SGOT, Gamma GT were assessed. The results showed overall decrease in lipid profile whereas Iyengariastellata increased liver enzymes except SGPT which was decreased highly significantly, since SGPT is more specific indicator of liver injury, decreased value of SGPT indicates that Iyengariastellata toxicity is less severe and reversible with marked hypolipidemic effect, but during the course of ingestion of the seaweed the liver enzymes must be carefully monitored to ensure liver safety.

Chamomile is considered as one of the oldest and also documented as medicinal plant. It has shown to be an anti-inflammatory, astringent and antioxidant especially in floral part since ancient times. Recent studies reported that chamomile has potential to lower blood sugar levels in hyperglycemia. In the present study we have investigated the pharmacological effects of chamomile tea on fasting and post prandial glucose levels and HbA1C in blood of diabetic rats (alloxan induced) and the results were compared with glibenclamide as standard. Statistical analysis was performed using SPSS. It has been observed in our study that it has reduced progressively the fasting and post prandial blood sugar levels, significantly in alloxan induced diabetic rats particularly on day 30 and 60. It also reduced the level of HbA1C significantly at the end of the study and the effects were similar to that of the standard group. Chamomile tea administration has also controlled the reduction in weight in diabetic rats as compared to diabetic control and the results were not very much different from standard. Results from the present study indicate that chamomile tea have a glucose lowering effect in diabetic rats so its daily consumption can be potentially useful in hyperglycemia and it can be used as a substitute of conventional drug treatment. Further studies are necessary to elucidate the exact molecular mechanism involved in anti-diabetic action of chamomile.

Several plants have been selected based on their use in traditional systems of medicine, and research has identified a number of natural compounds that could act as Nootropicagents. In this study a herbal product Intellan containing Centella asiatica, Bacopa monniera, Coriandum sativum, Amomum subulatum, Emblica officinalis and another product Cytacon (Cyanocobalamine) were selected The study was designed on animal models to explore the effects on different parameters. For this the animals were given chronic dosing for 6-8 weeks during and after which the parameters were observed to determine their effects. The purpose of focusing on such formulations is to do hematological screening in long-term use. The hematological parameter included hemoglobin/HCT, total leucocyte count, platelets. The lymphocytes and the monocytes counts were increased significantly by intellan, while cyanocobalamine increases RBC counts, platelet counts, monocyte counts, hematocrit etc significantly. The SGPT, SGOT were found increased in both of these drugs.

This prospective study included 50 patients receiving anterior cervical discectomy and fusion (ACDF) was conducted at Mymensingh Medical College Hospital, Mymensingh, Bangladesh. The study period was 1st July 2006 to 30th June 2010. This study was done to see the functional outcome of surgery in relation to duration of symptoms and age of the patient. The clinical information and relevant imaging of 50 consecutive patients, 41 male and 9 female, was reviewed at 1 year after surgery. All surgery was performed at no more than 2 contiguous levels, by one surgeon. After anterior discectomy alone, or combined with posterior vertebral body margin osteophytectomy, anterior bone grafting was performed at each level using a tricortical autogenous iliac crest bone block inserted under compression. All surgery was completed without internal fixation. A postoperative semirigid cervical collar was prescribed for 2 months. In 50 patients, there were 4 pseudarthroses (8%). Only 4% of the 50 patients had pain related to the donor site. The functional outcome was excellent to good (87.5%) when duration of symptoms less than 1 year and outcome was excellent to good (85.29%) when the age less than 50 years. These results tend to confirm published reports of most expected outcome related to young age and short duration of symptoms. Patients with technically successful fusions were less likely to have postoperative neck pain. Donor site pain was not a significant postoperative complication. ACDF is a safe, cheap and effective procedure for cervical spondylosis. In this series no major operative complications have occurred. No extra expenditure for plate and screw in this procedure.

Subdural empyema is a known disease entity; however, calcified subdural empyema is uncommon. The authors present a case of an 11-year-old boy in whom there was diagnosed a chronic calcified subdural empyema 10 years after an attack of meningitis. The patient had suffered from generalized tonic clonic seizures occurring 2-6 times in a month. A large fronto-temporo-parietal craniotomy was carried out and the subdural empyema filled with numerous uncharacteristic tissue fragments with thick pus together with the partially calcified and ossified capsule was removed. The empyema mass was found to be sterile for bacteria. After the operation, no epileptic seizure occurred and the boy is on sodium valporate. We must emphasize the unusual occurrence of the chronic subdural empyema presenting with calcification-ossification and large size as observed in our case.

Obesity in pregnancy remains a significant health problem that result in physiological, emotional, social and economic consequences on woman, their families and society. Obesity is considered one of the nutritional problems complicating pregnancy in our country. This study was conducted in antenatal clinic at out patient department of Obstetrics & Gynecology, BIRDEM Hospital, one of the countries largest tertiary level hospitals, during January 2007 to December 2008. During the study period of two years, a total no. of 100 cases were enrolled in two groups. Out of this 50 were control and 50 were over weight and obese. In this study, Mean of height, weight and BMI of the over weight and obese group were 5.21±0.21, 79.35±13.66, 32.36±4.76 respectively. The Mean of birth weight, APGAR score after 1 min and after 5 min of the over weight and obese group were 3.07±0.75, 7.10±1.11, 9.92±0.98 respectively and in normal weight group were 2.74±0.55, 7.40±1.56, 9.92±1.83 respectively. There was significant difference in birth weight, APGAR score after 1 min between the groups (p<0.05) but there was no significant difference in APGAR score after 5 min between groups (p>0.05). Regarding the fetal outcome in this study, 20% of the over weight and obese group delivered macrosomic baby in comparison to only 4% in the normal weight group. On the other hand 46% of the case group had to refer their babies to the neonatal unit in comparison to only 12% in the control group. Gestational Diabetes Mellitus (GDM) (46%) and Preeclampsia (44%) developed more in obese group. Eighty eight (88%) of obese and overweight mother experienced in caesarean delivery. Asphyxia, Respiratory Distress Syndrome (RDS), congenital anomaly and prenatal death were more in the over weight and obese group than normal weight group. Thus, overweight and obesity has got significant deleterious effect on maternal and perinatal outcomes of pregnancy.

A case of a giant ependymal cyst in the fronto-parieto-temporal region in a 9 months old male baby, who presented with recent onset epilepsy, drowsiness and loss of vision. Neurosurgical intervention of this cystic lesion was curative. Interesting clinical and neuroimaging features are presented. This ependymal and primary intracranial cystic lesion which is rare. These are congenital, benign ependyma lined, commonly intraparenchymal and uncommonly extraparenchymal cysts in leptomeningeal location of variable size. Surgical intervention is warranted in cysts, which produce a mass effect and raised intracranial pressure.
