RESUMEN

Diabetes is a group of metabolic disorder effecting health of wide number of population and cause neuropsychological decline. In the present study, effect of AI leaves extract on neuropsychological behaviors was observed in diabetic rat's model. Rats were divided into 4 groups as control (saline treated healthy rats), positive control (pioglitazone treated diabetic rats), diabetic control (untreated diabetic rats) and AI leaves extract treated diabetic rats. Diabetes was induced by giving 35% fructose for 6 weeks and a single dose of Streptozotocin (40 mg/kg). After 3 weeks of treatment behavioral and biochemical analysis were done. Behavioral results revealed that induction of type 2 diabetes produced anxiety, depression, decreased motor activity and impaired recognition memory in rats. Treatment with AI leaves extract in diabetic rats significantly decreased anxiety, depression, increased motor activity, enhanced recognition memory. Biochemical investigation revealed that AI leaves extract treat diabetes via improving the levels of fasting insulin and HbA1c and a significant decrease in CK and SGPT levels were observed in AI leaves treated diabetic rats. So, AI besides treating diabetes, helps in lowering the risk of co-occurring diabetic diseases and found effective in lowering neuropsychological decline observed in type 2 diabetes.

RESUMEN

Surface water from rivers, lakes, reservoirs etc. needs to be treated prior to municipal supplies. The treatment scheme includes coagulation, flocculation, sedimentation, filtration and finally disinfection process. Huge volume of sludge or waste is generated during the coagulation-flocculation. Disposal of the sludge so generated in the treatment plants require careful consideration for managing it sustainably and in an environment friendly manner. Constructive utilization of the inevitable waste may help in finding a sustainable solution to sludge disposal problems. Presently, response surface methodology (RSM) with central composite design (CCD) has been applied to simultaneously model coagulant recovery as well as reuse parameters. In order to simplify the process and increase the applicability, the effect of three significant variables, acid dose, sludge ratio, and recovered coagulant dose are studied. A second order regression model has been developed which gave the optimum combination of acid dose of 30 ml/L, sludge ratio of 1% and recovered coagulant dose of 12 ml/L for maximum turbidity removal. The predicted value of turbidity removal is 95.4%. In the confirmatory experiments, the turbidity removal value was observed to be about 96.2%, which is in good agreement with the predicted value. In addition to turbidity removal, it also helps to effectively remove other impurities from the raw water for it to meet the standards prescribed for potable supply. Thus, the regenerated alum or recovered coagulant has the potential to substitute the conventional coagulants, fully or partially at water treatment plants.

RESUMEN

Floods are among the most devastating natural hazards in Bangladesh. The country experiences multi-type floods (i.e., fluvial, flash, pluvial, and surge floods) every year. However, areas prone to multi-type floods have not yet been assessed on a national scale. Here, we used locally weighted linear regression (LWLR), random subspace (RSS), reduced error pruning tree (REPTree), random forest (RF), and M5P model tree algorithms in a hybrid ensemble to assess multi-type flood probabilities at a national scale in Bangladesh. We used historical flood data (1988-2020), remote sensing images (e.g., MODIS, Landsat 5-8, and Sentinel-1), and topography, hydrogeology, and environmental datasets to train and validate the proposed algorithms. According to the results, the stacking ensemble machine learning LWLR-RF algorithm performed better than the other algorithms in predicting flood probabilities, with R2 = 0.967-0.999, MAE = 0.022-0.117, RMSE = 0.029-0.148, RAE = 4.48-23.38%, and RRSE = 5.8829.69% for the training and testing datasets. Furthermore, true skill statistics (TSS: 0.929-0.967), corrected classified instances (CCI: 96.45-98.35), area under the curve (AUC: 0.983-0.997), and Gini coefficients (0.966-0.994) were computed to validate the constructed (LWLR-RF) multi-type flood probability maps. The maps constructed via the LWLR-RF algorithm revealed that the proportions of different categories of flooding areas in Bangladesh are fluvial flooding 1.50%, 5.71%, 12.66%, and 13.77% of the total land area; flash floods of 4.16%, 8.90%, 11.11%, and 5.07%; pluvial flooding: 5.72%, 3.25%, 5.07%, and 0.90%; and surge flooding, 1.69%, 1.04%, 0.52%, and 8.64% of the total land area, respectively. These percentages represent low, medium, high, and very high probabilities of flooding. The findings can guide future flood risk management and sustainable land-use planning in the study area.

RESUMEN

In the current study, we investigate the dynamic association of tourism, renewable energy, income, foreign direct investment (FDI), and carbon dioxide (CO2e) for Pakistan over 1990-2017. We established four plausible hypotheses and verified by employing the autoregressive distributed lags model and Granger causality based on vector error correction model (VECM). Considering the cointegration relationship between the variables, the outcomes of autoregressive distributed lags suggested that tourism increases economic growth, and economic growth induces tourism in the long-run, thus confirming tourism-led development, and growth-led tourism hypothesis; similarly, the tourism generates CO2e emissions, which supported the tourism-led emission hypothesis. The role of renewable energy consumption found to be a significant moderator, thus helping to enrich tourism, accelerating economic growth, and combating CO2e in the country. VECM causal results indicated the significant bidirectional causal linkages between tourism and economic growth-another causality found between tourism and CO2e. There is one-way causality from FDI and renewable energy towards income simultaneously. Overall, the designers of policies will find this study useful for policymaking at government levels for smooth economic growth, investment, and sustainable tourism sector.

RESUMEN

Reserpine (Res)-induced depletion of monoamines and altered neurotransmission and produces oxidative stress. Tryptophan (TRP) regulated the serotonin neurotransmission. Because systemically injected Res induced behavioral deficits and oxidative stress, while, dietary components prevented these adverse effects, we used TRP a pharmacological tool to prevent Res- induced changes in behavior, memory impairments, oxidative stress and regulation of serotonin neurotransmission in rats. Anxiolytic, antidepressant, cognitive functions, lipid peroxidation, antioxidant enzymes serotonin metabolism were studied in Res and vehicle treated animals following administration of 50 and 100 mg/ml/kg of tryptophan. Following administration of TRP [50 and 100mg/ml/kg], Res induced anxiety-and/or depression like behaviors normalized. Res-induced impaired cognitive function and increased acetylcholinesterase activity also improved following administration of TRP at both doses. Res induced increased brains' malondialdehyde (MDA) and decreased antioxidant enzymes activity also normalized by TRP. Res-induced decreased 5-HT metabolism also regulated by administration of TRP at both doses. In conclusion it can be recommended that administration/supplementation of TRP in daily life can aid in battling the anxiety, depression, modulating serotonergic activity and oxidative stress. Study also exhibits the anti-acetylcholinesterase role of TRP which may be possible reason for improved cognition following stress situation.

RESUMEN

The study is aimed to evaluate the protective impact of banana peel extract (BPE) following noise induce behavioral deficits in male mice. Animals were separated into two groups (control and test, 12 in each). Control mice were given drinking water, at the same time test group was given BPE (400 mg/kg; oral administration). Animals have received their respective treatment for 14 days. Mice were subdivided (n=6) into unstressed and stressed groups on day 15. Noise stress was given to the respective group for 4-h. Behavioral activities were monitored 24-h after the 4-h noise stress. Forced-swim-test, Elevated-plus-maze and light-dark-activity-box tests were performed for depression/anxiety-like behaviors respectively. Morris-water-maze assessment was used for memory. After behavioral tests animals were sacrificed and brain was detached for biochemical estimations and histopathological studies. In the present study, BPE produced anxiolytic and antidepressant-like effects and enhanced memory. Activity of antioxidant enzymes increased while levels of AChE and MDA decreased in BPE treated animals. Histopathological alterations induced by noise stress were also normalized by BPE. It is concluded that supplementation/administration of banana peel has preventive effects against anxiety, depression and memory impairment via its strong antioxidant potential following NS.

RESUMEN

Nanotechnology is a field of science that consists of atoms, molecules and supramolecular molecules that create nanoparticles ranging in size from 1-100nm. Silver nanoparticles are widely used that are considered as effective antimicrobial agents. In this paper, the antioxidant activity of biosynthesized SNPs were analyzed by the DPPPH activity, hydrogen peroxide activity, hydroxyl RSA, TAC, TFC; their results confirmed that the phenolic compounds of this plant peels extracts enhanced the antioxidant and antiglycation activity with respect to silver nanoparticles. Biosynthesized nanoparticles of this plant extracts also showed strong zone of inhibition against the different Xanthomas, Pseudomonas and E. coli. This study concluded that biosynthesized nanoparticles of Mukia maderaspatna (M.M) plant peels extracts have the great biological activities i.e. antiglycation, antioxidant and antibacterial. More research is needed to know the exact dose rate and to compare the different dose combination of the plant with the strong antibiotic agents against these bacteria.

RESUMEN

Large volume of sludge is generated at the water treatment plants during the purification of surface water for potable supplies. Handling and disposal of sludge require careful attention from civic bodies, plant operators, and environmentalists. Quantification of the sludge produced at the treatment plants is important to develop suitable management strategies for its economical and environment friendly disposal. Present study deals with the quantification of sludge using empirical relation between turbidity, suspended solids, and coagulant dosing. Seasonal variation has significant effect on the raw water quality received at the water treatment plants so forth sludge generation also varies. Yearly production of the sludge in a water treatment plant at Ghaziabad, India, is estimated to be 29,700 ton. Sustainable disposal of such a quantity of sludge is a challenging task under stringent environmental legislation. Several beneficial reuses of sludge in civil engineering and constructional work have been identified globally such as raw material in manufacturing cement, bricks, and artificial aggregates, as cementitious material, and sand substitute in preparing concrete and mortar. About 54 to 60% sand, 24 to 28% silt, and 16% clay constitute the sludge generated at the water treatment plant under investigation. Characteristics of the sludge are found suitable for its potential utilization as locally available construction material for safe disposal. An overview of the sustainable management scenario involving beneficial reuses of the sludge has also been presented.

RESUMEN

Coagulation-flocculation process results in the generation of large volume of waste or residue, known as water treatment sludge (WTS), in the purification of surface water for potable supplies. Sustainable management of the inevitable waste requires careful attention from the plant operators and sludge managers. In this study, WTS produced with the optimum alum dose of 30 ml/L at the laboratory scale has been treated with sulphuric acid to bring forth a product known as sludge reagent product (SRP). The performance of SRP is evaluated for its efficiency in removing the colloidal suspensions from the Yamuna river water over wide pH range of 2-13. 1% sludge acidified with sulphuric acid of normality 2.5 at the rate of 0.05 ml/ml sludge has been observed as the optimum condition for preparing SRP from WTS. The percentage turbidity removal is greater at higher pH value and increases with increasing the dosage of SRP. The optimum SRP dosage of 8 ml/L in the pH range of 6-8 performed well in removing the colloidal suspension and other impurities from the Yamuna water. The quality of treated water met the prescribed standards for most of the quality parameters. Thus, SRP has the potential to substitute the conventional coagulants partially or completely in the water treatment process, depending on the quality needed at the users end.

RESUMEN

The current study was aimed to judge bioequivalence between two formulations of cefadroxil capsules as guided by FDA guidelines. Another objective was to conduct pharmacokinetic evaluation in Pakistani population. A single-dose, randomized, cross-over pharmacokinetic study was conducted during the month of May'2013 to August'2013. Washout period was one week. Fourteen healthy male adult volunteers were enrolled in the study, however twelve completed the study. Cefadroxil plasma concentration was analyzed by using validated HPLC method. Protein precipitation was achieved by the addition of 6% tri chloro acetic acid in 1:1 ratio and detection was done at 260 nm. Retention time was 7.792 min and correlation coefficient (R2) was 0.9953 showing linearity of the method. Blood sampling was carried out at different time intervals after administration of either test (TEST 500 mg) or reference (REF® 500 mg) formulation. Pharmacokinetic parameters (AUC0→ ∞, AUC0→ t, Cmax, Tmax, t1/2 and kel) were calculated using Kinetica® PK/PD software. The geometric mean ratios and 90% confidence interval (CI) of these pharmacokinetic parameters for cefadroxil (test and reference) formulations were 0.986 (90.83-106.98%) for AUC0→ t; 0.967 (89.13-104.92%) for AUC0→ ∞ and 0.999 (91.06-109.69%) for Cmax. The differences between Tmax of both formulations were not found to be statistically significant (p-value was more than 0.05). The 90% CI of the test/reference AUC and Cmax ratio of cefadroxil were within the FDA recommended range for bioequivalence. Maximum plasma concentration Cmax was 12.5 µg/ml for test and 12.47 µg/ml for reference formulations. Average time to reach Cmax for test and reference formulation was 1.54 and 1.5 hrs. The two formulations of cefadroxil studied during the above study were verified bioequivalent. Maximum plasma concentration of cefadroxil was lower than those mentioned in some previous studies, while Tmax and half-life were near to values reported in literature.

RESUMEN

The tympanic membrane forms a barrier between the external auditory canal and the middle ear. In the inactive mucosal type of chronic otitis media, there is a perforation in the tympanic membrane which is surgically managed by Myringoplasty. Estrogen as a growth factor has been shown to have a mitogenic effect on keratinocytes thus hastening the rate of epithelialization following injury. This property of estrogen is being studied in this study for its role in the outcomes of myringoplasty. This study was carried out from January 2021 to December 2022 in the Department of Otorhinolaryngology, of a tertiary teaching hospital in North India. Patients were assessed by history, examination, otoscopy, Audiometry, and oto-endoscopy. A total of 88 patients were taken out of which 44 patients underwent myringoplasty in which topical estrogen (estradiol valerate solution) was used, and the remaining 44 patients were taken as controls. Patients were then assessed post-operatively based on Audiometry results and graft uptake status. In the estrogen group successful Graft uptake was in seen 40 (90.9%) patients and failed in 4 (9.1%), while in the control group, it was successful in 37 (84.1%) patients and failed in 7 (15.9%), statistically there was no significant difference between two groups in terms of graft uptake (p value = 0.334). Post-operatively, in the estrogen group, the mean change in Air Conduction (AC) was 15.5 dB, the change in the air-bone gap (ABG) was 11.5 dB and for Bone Conduction (BC) it was 3.2 dB. However, in the control group mean post-operative changes in Air Conduction, Air-Bone Gap, and Bone Conduction were 12 dB, 10.7 dB, and 0.8 dB respectively. Statistically, there was a significant difference in postoperative changes in AC (p value = 0.011) and BC (p value = 0.009) between the two groups. There was no significant difference in post-operative changes in Air-Bone Gap (p value = 0.571). Topical Estrogen (Estradiol valerate) solution is cost-effective, with enriched growth factors that accelerate tympanic membrane perforation closure following myringoplasty and resulted in significant improvement in hearing thresholds both for Air Conduction and Bone Conduction.

RESUMEN

Scorpion venoms are known to contain over 100,000 biologically active constituents. However, only a few of them have been studied. The major constituents of venom are proteins and peptides, which exhibit various biological and pharmacological properties, including anticancer activities. In the current study, the venom of yellow scorpions (Buthus sindicus) found in Sindh, Pakistan, was extracted and evaluated for its anti-cancer and anti-inflammatory activities. The crude venom showed a dose dependent inhibition of phagocyte oxidative burst from human whole blood cells (28.3% inhibition at highest tested concentration of 300 µg/mL). In-vitro cytotoxicity of crude venom was evaluated against human prostrate (PC3), cervical (HeLa) and neuroblastoma (U87-MG) cell lines, along with cytotoxicity against normal human fibroblast (BJ) cells. Crude venom was cytotoxic to all cell lines, with prominent inhibitory effect on PC3 cells. Crude venom was fractionated through RP-UPLC, resulted in fifteen fractions, followed by evaluation of their anticancer potential. Among all, the fraction I significantly (P < 0.001) reduced the cell viability of all three cancer cell lines, and exhibited insignificant cytotoxicity against normal cell line. Furthermore, the apoptotic cell death pathway was evaluated for crude venom, and fraction I, in most sensitive cell line PC3, by using flow-cytometry analysis. Both crude venom and its fraction I caused a mitochondrial-mediated apoptosis in prostate cancer cells (PC3). To the best of our knowledge, this is the first report of the anticancer and anti-inflammatory activity of venom of Pakistani yellow scorpions. Results indicate their therapeutic potential, and a case for further purification and validation studies.

RESUMEN

Epithelial-Myoepithelial Carcinoma (EMC) is a very rarely seen biphasic tumour typically seen in older females and constitutes 0.5-1% of all salivary gland neoplasms. The parotid gland is most often involved and occasionally there may be involvement of submandibular and minor salivary glands. Clinical picture often reveals benign nature of the disease. Computed tomography (CT) and magnetic resonance appearances are non-specific and the cytological diagnosis may be challenging, thus more accurate diagnosis can only be made by histological and immunohistochemical study. There is no consensus regarding the optimal treatment of this neoplasm, largely due to its rarity. Wide surgical excision with a clear margin is the treatment of choice because of the tumour's tendency to infiltrate locally. Adjuvant radiotherapy is often required in cases of large primary tumours and positive surgical margins. The tumour may commonly recur locally after resection in 30-50% of cases. We herein present an unusual case of a 46-year-old male who presented with cystic swelling of left parotid gland and diagnosed as EMC on histopathology and immunohistochemical examination. The patient was treated with surgical resection followed by post-operative radiotherapy.

RESUMEN

This prospective study has been carried out to observe the outcomes of canal wall up (CWU) and canal wall down (CWD) Tympano-mastoidectomies in ears with cholesteatoma. Outcomes of the procedures have been done in terms of recurrence of cholesteatoma, complications, graft uptake rates and post-operative hearing gain. This study was carried out in the Department of Otorhinolaryngology of a reputed tertiary teaching hospital of North India from January 2016 to June 2020, with a mean follow-up of 32 months. The study included 100 patients of otitis media with cholesteatoma. In Canal Wall Up Tympano-mastoidectomy (CWUT) group, the number of males and females were 22 each. On the other hand, 36 males and 20 females underwent Canal Wall Down Tympano-mastoidectomy (CWDT). Each surgery was done as a single-staged and at the end of the surgical procedure angled oto-endoscopes were used for ensuring complete removal of the disease. Though there is no statistically significant difference in recurrence of cholesteatoma and complications rate in CWU and CWD Tympano-mastoidectomy techniques, but CWUT is superior to CWDT in terms of better graft uptake (p = 0.0156), and better average audiological gain (8.56 ± 0.93 dB) with p value = 0.0315. A diligent post-operative follow-up is must for assessing the outcomes of different types of mastoidectomies. This study shows no statistical difference in the disease recurrence and complication rates between Canal Wall Up and Down Tympano-mastoidectomies, though the anatomical changes and creation of the mastoid cavity in canal wall down procedure may affect the graft uptake and post-operative hearing gain. Use of Oto-endoscopes in cholesteatoma surgery helps in improving the outcomes of both techniques and thus recommended if the facility for the same is available.

RESUMEN

The bacteriological and antimicrobial sensitivity profile of chronic otitis media (COM) varies from region to region and from time to time and may vary among different age group as well. It was against this backdrop of the changing bacteriological profile and sensitivity pattern together with the paucity of categorically separated data of pediatric and adult population, that the present study was undertaken. A total of 193 patients of clinical diagnosis of cholesteatomatous COM with ear discharge and positive culture results were included in the study. Pus sample was collected under aseptic conditions and cultured on solid media and broth. Isolates were identified via standard biochemical tests and sensitivity patterns analysed. Chi square (χ2) test was used to analyse the significance. Pseudomonas was the most common isolate in both the pediatric (37.80%) and adult (51.46%) population. Methicillin sensitive staph aureus (MSSA) was found exclusively in pediatric population (p = 0.003).Piperacillin-Tazobactam combination was the single most effective drug regimen overall. 75% of pseudomonas isolates in pediatric and 87.5% in adults were sensitive to this regimen in vitro. Amikacin was the next most effective drug with 56.69% sensitivity in pediatric and 64.08% sensitivity in adult population. The present study finds piperacillin-tazobactam as the most effective therapy and pseudomonas as the most common isolate in the study population.In order to address the varying and changing bacteriological and sensitivity profile of chronic otitis media occurring among different geographical regions and also within a region over time, the authors recommend its periodic evaluation.

RESUMEN

As there are changing trends in the microbiology of chronic otitis media, this study was carried out to look for the current aerobic microbes and their antimicrobial susceptibilities in patients of chronic otitis media from north Indian region. A total of 322 patients who met the inclusion criteria were studied and aerobic ear swab culture was done under aseptic conditions. Gram staining was performed and antibiotic susceptibility testing was done using Kirby-Bauer disc diffusion method on Mueller-Hinton Agar. A total of 341 culture positive results were obtained from 322 patients. The culture results revealed 10 different aerobic microbes. Gram-positive floras were seen in 152 (44.57%), and Gram-negative in 189(55.43%) isolates. Staphylococcus aureus was the most common isolate present in 131 samples (38.41%), followed by pseudomonas aeruginosa in 101 (29.62%) and proteus in 36 (10.56%). In overall susceptibility of antibiotics against Gram-positive culture isolates, Vancomycin was most effective (97.37%). For Gram-negative microbes, Piperacillin-Tazobactum combination was most effective with overall susceptibility of 79.37% susceptibility. Microbiological assessment of Chronic Otitis Media should be carried out in an area on regular intervals because of the changing patterns of bacteriology and their antimicrobial susceptibilities.

RESUMEN

INTRODUCTION: Osteochondroma of the coronoid process also known as Jacob's disease, has rarely been reported in the literature and it posses a challenge as diagnosis may be overlooked in favour of other causes of limited mouth opening. CASE REPORT: This is a case report of an adult male patient who presented with restricted mouth opening in whom radiological imaging, especially 3D computed tomography, played a role in establishing the diagnosis of Jacob's disease. CONCLUSION: An osteochondroma of the coronoid process of the mandible (Jacob's disease) is a rare cause of restricted mouth opening and its diagnosis can be overlooked in favour of TMJ ankylosis.

RESUMEN

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a form of autoimmune encephalitis. The characteristic clinical features include seizure, psychosis-like symptoms, abnormal movements, and autonomic disturbances. Patients with anti-NMDAR encephalitis can present with various types of movement disorders. Typically, the movement disorders start following intervals of psychiatric and prodromal manifestations in young adults; however, in children, these might be an early presentation of anti-NMDAR encephalitis. The disease is under-recognized and underdiagnosed in Pakistan. Early recognition of the disease is important to commence timely treatment leading to a better prognosis. Here we present a collection of anti-NMDAR encephalitis patients, specifically focussing on the different types of movement disorders and the differences in clinical manifestations between children and adults.

RESUMEN

Autoimmune limbic encephalitis is a rare autoimmune disease characterised by inflammation of the limbic system of the brain. The disease runs a sub-acute course with cognitive impairment, memory loss and seizures. These patients have been underdiagnosed in Pakistan. Here, we present a case of a middle-aged male, who presented to our Department after having multiple visits to different psychiatrists for his symptoms. The patient had been put on multiple psychiatric and antiepileptic medications, but his condition gradually declined. At our Department, he was thoroughly assessed and then diagnosed as limbic encephalitis on the basis of the typical history, positive anti-leucine-rich-glioma-inactivated 1 (LGI1) antibodies and MRI findings. The patient responded to plasmapheresis and immune modulating therapy and is being followed up. Emphasis is made on early diagnosis; and earlier treatment of such cases, as it holds a substantial importance in management and makes a difference in future outcome. Key Words: Autoimmune limbic encephalitis, Voltage-gated potassium channels, Cognitive dysfunction.
