Sun, 10 Nov 2024 00:00:00 +0200

Karachi is Pakistan's largest city, with all the features of a densely populated metropolitan. One of the city's significant issues is air quality, which is linked to the urban environment and pollution. The goal of this study is to show how Geographic Information Systems (GIS) can help with exposure, risk assessment, and emission predicting in Karachi. The study's major goal is to develop a GIS model that can analyze, predict, and analyze carbon monoxide (CO) levels throughout the city as pollution surface. To achieve this objective and aim, sample data have been collected, processed, and managed to generate a dynamic GIS model of Carbon monoxide levels of the study area. To better visualization and analysis, GIS and geostatistical (interpolation) models are used to develop interactive and dynamic CO pollution models. Inverse distance weighted (IDW) interpolation was used to create a surface from CO survey data. For the evaluation of CO, zonal statistics were used as districts wise Minimum, Maximum, Range, Mean and Standard Deviation values. The mean values of later districts were used for mapping displays. Data collected in the field and analyzed during the inquiry found that (CO) emissions were within acceptable ambient air quality requirements and limits. However, carbon monoxide (CO) levels are higher in business zones and commercial marketplaces in the central city, this area is more likely to cause respiratory problems.

Orchidaceae is the second largest plant family with between 600-800 genera and 25,000-35,000 species. The beauty of the orchids mesmerizes human beings and creates a billion-dollar market worldwide. The aim of this study was to establish the cost-effective growth method to produce commercially important orchid plants in shorter time duration. The growth and development of orchids were established through plant tissue culture based micro propagation and were acclimatized for healthy growth through a hydroponic system. Under this study the shooting of orchids was obtained on the reported media androoting of orchids was optimized. Different concentrations of NAA (naphthaleneacetic acid) from 0mg/l to 0.8mg/l were tested for the development of orchid roots. The highest number of roots (12) was obtained at 0.6mg/l NAA whereas highest lengths of roots (1.8cm) were observed at 0.8mg/l NAA. In this study nutrient sprays were tested for the acclimatization and growth of orchids. Three different types of nutrient solutions like NPK, Hoag land and MS Macro and Micro were tested. Results indicate that among three nutrient solutions, NPK 20:20:20 (Nitrogen, Phosphorous, and Potassium) was the best nutrient solution for the effective growth and development of commercially important orchids. Therefore, this protocol was found to be most effective for the micro propagationof commercially important orchid plants.

Sun, 10 Nov 2024 00:00:00 +0200

For domestic consumption, the quince (Cydonia oblonga) is grown throughout Pakistan's temperate regions, particularly the upland areas of Balochistan. Despite its importance, the province has notably lacked nutritional composition profile for quince. This study investigates the mineral and proximate compositions of quince fruit and leaves. Matured quince fruits and leaves were systematically collected from Khanozai (Kn) and Churmian (Ch) area in the Pishin district of Balochistan. Leaf sampling was conducted in July 15, 2021, where leaves from twelve shoots per tree and four leaves per shoot were collected from six randomly selected quince trees. While, 4-8 fresh yellow Cydonia oblonga fruits per tree were collected In October 2021 and analyzed for proximate and nutrient analysis. The results revealed disparities in mineral concentrations, with Churmian area exhibiting higher levels of Nitrogen (0.077%), Potassium (1.66%), Iron (872.32 mg kg-1 ), and Zinc (30.423 mg kg-1 ) compared to Khanozai. However, Manganese was not detected in the fruits from either location. The analysis of Cydonia oblonga leaves displayed statistically significant differences in Potassium, Sodium, Copper, Iron, Zinc, and Manganese content, while Nitrogen and Phosphorus showed no significant variation. Proximate analysis of both fruit and leaves exhibited statistically significant differences across locations, with Khanozai recording the highest ash content in both fruit (2.62%) and leaves (9.59%), whereas Churmian area showcased the maximum protein content in the fruit (0.47%). Interestingly, crude fiber showed non-significant differences. This exploration provides fundamental insights into the Proximate and nutritional characteristics of quince fruit and leaves cultivated in Khanozai and Churmian, offering a crucial foundation for further research in this field.

Sun, 10 Nov 2024 00:00:00 +0200

Levocetirizine, a levorotatory enantiomer of anti-histamine cetirizine, available as hydrochloride and useful in the management of intermittent or persistent allergic rhinitis and hay fever. Levocetirizine may interact different drugs including NSAIDswhich may cause severe adverse effects as a result of drug interactions. UV spectroscopy is a precise and applicable method with less time consumption for the calibration curve study, quantification of drugs and also to estimate drug availability alone or in the presence of another drug. In the present study, levocetirizine, diclofenac sodium, flurbiprofen, mefenamic acid and meloxicam (reference standards) were submitted for calibration curve studies, lonequantification and finally percentavailability after drug interaction of levocetirizine with diclofenac sodium, flurbiprofen, mefenamic acid and meloxicam at pH 4, 7.4 and 9 whichmight resulted in increased, decreased or even loss of availability of the drugs. Diclofenac sodium decreased availability of levocetirizine up to 0.0% at pH 4 and 9 but increased at pH 7.4. On the other hand, levocetirizine decreased percent availability of diclofenac sodium by 4.9% pH4 but increased 170% and 206.57 % at pH 7.4 and 9.Flurbiprofen interactions with levocetrizine in different buffers and showed significant rise in availability of levocetirizine in all pH but showed significant decreased availability of flurbiprofin in three buffers. Mefenamic acid caused decreased in pH 7.4 but increased in pH 9. However, availability of mefenamic acid was decreased in both pH. Although, availability of levocetirizine doesn’t seem to be effected a lot in the presence of meloxicam but meloxicam was significantly decreased in pH 4 and 7.4. Further, in vivo studies should be conducted to ensure and avoid the adverse effects as result of these interactions. Precaution should be taken and co-administration of levocetirizine with NDSAIDs should be avoided and time duration between these drugs taken should be adjusted.

PATIENT EDUCATION AS A TOOL FOR ENHANCED DIABETES MANAGEMENT: A CASE STUDY FROM CIVIL HOSPITAL, HYDERABAD, SINDH, PAKISTAN"

Sun, 10 Nov 2024 00:00:00 +0200

Diabetes mellitus is the most frequent disease globally, with 26.7% of adults affected in Pakistan in 2022. Factors contributing to this increase include lack of awareness, unhealthy diets, hypertension, and mental health issues. Despite the challenges, self-care plays a significant role in managing diabetes. Our study investigates health literacy and selfpractices among diabetic patients through criteria sampling in public hospitals of Hyderabad Sindh, and to provide guidelines about diet to make people aware of healthy choices in the future. The present study was conducted at a civil hospital. 110 patients were selected from civil hospitals in the months of August and September, which included 50 males and 60 females. The self-care practice was carried out by a questionnaire that consisted of demographic characteristics, self-care management practices, diabetic complications, and dietary management of patients. Among the total samples, the majority of patients with poor self-care practices were found to be unsatisfactory. The reasons are a lack of awareness, financial crises among affected patients, and low implementation. Almost 80 patients were taking medicines, and 40 patients were following self-care. The major complications were patients with the highest ratio of diabetic feet in males due to injury and carelessness and the highest ratio of obesity in females. For patients in civil hospitals, managing their health care has become essential. Our study findings showed that diabetic patients require implementation of self-care, eat unprocessed food like vegetables, fruits, and limit sugary items to maintain glycemic control, use herbal medicine, and exercise daily all these can take an active role in managing their self-care.

Sun, 10 Nov 2024 00:00:00 +0200

The present research study was conducted in a cool winter with a hot summer region of Lasbela, Balochistan. The main purpose of this study was to evaluate the effects of the combined application of nitrogen and phosphorus fertilizers on wheat crops, associated with growth and grain yield. Factorial combinations of three of both N and P within the control (T1= control, T2= 30&15kgha-1, T3= 60&30kgha-1, T4= 90&45kgha-1) of three times replicates were laid out in a randomized complete block design. The findings of this study showed that the increased applications of both fertilizers influence wheat's growth and yield attributes. Growth parameter results indicated that plant height (cm), leaf length (cm), pedicel length (cm), and spike length (cm) increased with an increased dose of both fertilizers i.e. 70.66, 7.12, 24.7, 6.12cm; 73, 8.56, 30.53, 7.52cm; 88.312, 11.91, 36.3 and 10.12cm respectively. Mean maximum and significant p<0.05 were recorded in T4 compared to T1, T2, and T3. In the in-comparison of T1 and T2, a minor difference was recorded. Additionally, results of biological and grain yield also increased 8-10% more than T1 and T2 with increased application of both fertilizers. Conclusively, combined applications of both fertilizations within split doses and after the application irrigation have significantly interacted with the growth, biological, and yield attributes of wheat

Celiac disease is an autoimmune disorder triggered by gluten molecules. The proline-rich residues present in the grains mediate the adverse immune response in patients with celiac disease. There is a high prevalence of celiac disease in children as compared to adults in Pakistan. The association between psychiatric disorders and Celiac disease has long been known. There is a significant risk of the development of depression and other psychiatric symptoms in patients with celiac disease. Celiac disease also leads to gut dysbiosis. Lactic acid bacteria are gram-positive, acid-tolerant, rod or cocci-shaped bacteria. LAB produce anti-oxidant enzymes and degrades gluten molecules by producing proteolytic enzymes. They also mitigate the symptoms of depression by upregulating the enzymes, which are down regulated in depression. This present study aims to isolate lactic acid bacteria from local yogurt samples and to degrade the gluten molecules by sourdough fermentation with LAB. Yogurt samples were collected from various sites in Karachi. Lactic acid bacteria were isolated in MRS media, macroscopic and microscopic evaluation, and biochemical tests including catalase test was performed for confirmation of LAB. Sourdough fermentation with LAB isolates was carried out. A rapid test kit evaluated gluten molecule degradation. All isolates produced gas and bubbling when subjected to degrade wheat samples. However, isolate 9 gave the best results in terms of bubble formation, production of gas, and proofing of the sourdough when compared to the positive control. This study revealed that LAB significantly degrades the number of gluten molecules present in wheat during fermentation. Conclusion: This study aimed to isolate the lactic acid bacteria from yogurt, and its application in celiac disease. LAB products can be added to the diet of post-operative patient’s diets for better recovery as LAB will strengthen the immune system by the production of antioxidant enzymes. LAB can be used for the production of gluten-free products locally.
