Frequency of Impacted Third Molar in Mandibular Angle Fractures in Patients Presenting to Ayub Teaching Hospital

Mandibular fractures are one of the commonest maxillofacial injury. Fractures take place at various locations. Mandibular angle fracture susceptibility in addition to being associated to the type and direction of impact is also associated with impacted 3rd molar.The objective of the study is to determine the frequency of impacted third molar in mandibular angle fracture.This descriptive cross-sectional study was performed for a period of six months on one hundred and twenty-two patients with mandibular. OPG was done to determine the state of 3rd molar tooth. The states of 3rd molar tooth along with its inclination were noted on a proforma.The frequency of 3rd molar impaction in fractures of angle of mandible was 36.1%. Young age (less than 31 years in this study) was significantly associated with development of impacted 3rd molar tooth (p < 0.05).Individuals with impacted 3rd molar should be educated about the possibility of the fracture of mandibular angle so that preventive measures can be adopted

Assessment Of Iba (Indole Butyric Acid) Levels And Planting Time For Rooting And Growth Of Alstonia Cuttings

An experiment to assess different levels of IBA (Indole Butyric Acid) and planting time on rooting and growth of Alstonia cuttings was conducted at Ornamental Horticulture Nursery, Department of Horticulture, The University of Agriculture Peshawar, Pakistan. The experiment was carried out using RCBD design with split plot arrangement. There were five levels of IBA 0, 5, 10, 15 and 20% that were prepared by mixing IBA with talc powder. Cuttings were obtained from healthy, vigorous growing trees which were 15-20 cm long and 2-3 nodes. Leaves were removed from the cuttings and were treated with IBA than planted in plastic bags filled with mixture of sand, clay and FYM with the ratio of 1:1:1 on three different planting times 15th March, 30th March and 14th April. IBA level of 10% showed best results regarding leaf area plant-1(26.032 cm2), sprout length(18.096 cm), stem diameter (14.44 mm), number of roots plant-1 (15.613), root diameter (3.412 mm) while number of  leaves plant-1 (17.27), root length (14.24 cm) and survival percentage (70%) was best recorded when treated with IBA at level of 5%. However, sprouting percentage and days to bud sprouting were not significantly affected by different levels of IBA. It is observed from the study that there was no significant effect of planting time over any parameter however good results were observed in cuttings planted at 14th April regarding leaf area plant-1, sprout length, stem diameter, number of roots plant-1, number of leaves plant-1, root length, root diameter and survival percentage while sprouting percentage and days to bud sprouting were best when planted at 15th March. IBA at 10% level and 14th April as planting time resulted in overall best performance and hence recommended for treating and planting cuttings of Alstonia.

Morphology of the proximal femur in a Pakistani population

Purpose: To measure the morphology of the proximal femur in a Pakistani population. Methods: Standardised anteroposterior pelvic radiographs of 116 male and 20 female healthy volunteers aged 20 to 50 (mean, 33) years were taken. Morphologic dimensions of the proximal femur were measured, including canal flare index (CFI), morphological cortical index (MCI), femoral head offset, femoral head diameter, and femoral head position. Results: Based on the CFI, 67% of the subjects had normal canal shapes (CFI, 3.0-4.7), whereas 1% and 33% of the subjects had stovepipe shapes (CFI,2.7). Conclusions: Morphology of the proximal femur in our study population differed significantly from those in western populations, indicating regional variation. It could also be due to the younger age of our population

Neuropathic Changes of Osmicated Common Peroneal and Tibial Nerve in Diabetic Patients and the Related Risk Factors

      So much studies done to present the diabetic neuropathic changes of the peripheral nerves but most of them were done experimentally on laboratory animals , but little about human diabetic neuropathic and structural changes specially of large nerves like common peroneal and tibial nerve .Accordingly the present work designed to study the neuropathic changes of the tibial and common peroneal nerve samples, taken from amputated legs of 30 diabetic patients (8 females and 22 males) at age ranging between (55-75) years, and from 30 cadavers (4 females and 26 males) at age ranging between (25-50) years as control group. The teased and osmicated tibial and common peroneal nerve fibers, and histological sections taken from diabetic patients showed different deformity and Morphometrical changes, of that ; paranodal swelling, segmental demyelination, some areas with an areas of un even myelin and shortest segmentation the (common peroneal nerve 22µ and tibial nerve 265µ ) in comparison to the control group. The multiple regression analysis, showed significant effect of age of the patient and duration of diabetes on the neuropathic changes

Growth, Yield and Fruit Quality of Strawberry (Frageria ananasa Dutch) under Different Phosphorus Levels

Strawberry fruit takes less time for production and is easily multiplied. Fruiting is an exhaustive process and depletes nutrients especially phosphorus as it is highly immobile in the soil. An experiment was conducted in The University of Peshawar, Pakistan to evaluate different level of Phosphorous on growth, yield and fruit quality of Strawberry Cv Chandler. Results show that Phosphorus at 90 kg ha-1 significantly influenced the days to flowering (102.66) of strawberry plants while, at 80 kg ha-1 significantly affected days to fruit set (2.98), days to fruit maturity (20.05), Number of fruits (7.50) and Total fruit yield tons ha-1(3.61). Fruit size (6.42 cm3) was significantly affected at 70 kg ha-1. Similarly, Ascorbic acid (62.61), percent acidity (0.64) and Total soluble solids (7.83) were significantly affected by phosphorus at 60 kg ha-

A Novel Secure Occupancy Monitoring Scheme Based on Multi-Chaos Mapping

Smart building control, managing queues for instant points of service, security systems, and customer support can benefit from the number of occupants information known as occupancy. Due to interrupted real-time continuous monitoring capabilities of state-of-the-art cameras, a vision-based system can be easily deployed for occupancy monitoring. However, processing of images or videos over insecure channels can raise several privacy concerns due to constant recording of an image or video footage. In this context, occupancy monitoring along with privacy protection is a challenging task. This paper presents a novel chaos-based lightweight privacy preserved occupancy monitoring scheme. Persons’ movements were detected using a Gaussian mixture model and Kalman filtering. A specific region of interest, i.e., persons’ faces and bodies, was encrypted using multi-chaos mapping. For pixel encryption, Intertwining and Chebyshev maps were employed in confusion and diffusion processes, respectively. The number of people was counted and the occupancy information was sent to the ThingSpeak cloud platform. The proposed chaos-based lightweight occupancy monitoring system is tested against numerous security metrics such as correlation, entropy, Number of Pixel Changing Rate (NPCR), Normalized Cross Correlation (NCC), Structural Content (SC), Mean Absolute Error (MAE), Mean Square Error (MSE), Peak to Signal Noise Ratio (PSNR), and Time Complexity (TC). All security metrics confirm the strength of the proposed scheme

Utility of the CHA2DS2-VASc score for predicting ischaemic stroke in patients with or without atrial fibrillation: a systematic review and meta-analysis

AIMS: Anticoagulants are the mainstay treatment for stroke prevention in patients with non-valvular atrial fibrillation (NVAF), and the CHA2DS2-VASc score is widely used to guide anticoagulation therapy in this cohort. However, utility of CHA2DS2-VASc in NVAF patients is debated, primarily because it is a vascular scoring system, which does not incorporate atrial fibrillation related parameters. Therefore, we conducted a meta-analysis to estimate the discrimination ability of CHA2DS2-VASc in predicting ischaemic stroke overall, and in subgroups of patients with or without NVAF. METHODS AND RESULTS: PubMed and Embase databases were searched till June 2020 for published articles that assessed the discrimination ability of CHA2DS2-VASc, as measured by C-statistics, during mid-term (2-5 years) and long-term (\u3e5 years) follow-up. Summary estimates were reported as random effects C-statistics with 95% confidence intervals (CIs). Seventeen articles were included in the analysis. Nine studies (n = 453 747 patients) reported the discrimination ability of CHA2DS2-VASc in NVAF patients, and 10 studies (n = 138 262 patients) in patients without NVAF. During mid-term follow-up, CHA2DS2-VASc predicted stroke with modest discrimination in the overall cohort [0.67 (0.65-0.69)], with similar discrimination ability in patients with NVAF [0.65 (0.63-0.68)] and in those without NVAF [0.69 (0.68-0.71)] (P-interaction = 0.08). Similarly, at long-term follow-up, CHA2DS2-VASc had modest discrimination [0.66 (0.63-0.69)], which was consistent among patients with NVAF [0.63 (0.54-0.71)] and those without NVAF [0.67 (0.64-0.70)] (P-interaction = 0.39). CONCLUSION: This meta-analysis suggests that the discrimination power of the CHA2DS2-VASc score in predicting ischaemic stroke is modest, and is similar in the presence or absence of NVAF. More accurate stroke prediction models are thus needed for the NVAF population

A Novel Hybrid Secure Image Encryption Based on Julia Set of Fractals and 3D Lorenz Chaotic Map

Chaos-based encryption schemes have attracted many researchers around the world in the digital image security domain. Digital images can be secured using existing chaotic maps, multiple chaotic maps, and several other hybrid dynamic systems that enhance the non-linearity of digital images. The combined property of confusion and diffusion was introduced by Claude Shannon which can be employed for digital image security. In this paper, we proposed a novel system that is computationally less expensive and provided a higher level of security. The system is based on a shuffling process with fractals key along with three-dimensional Lorenz chaotic map. The shuffling process added the confusion property and the pixels of the standard image is shuffled. Three-dimensional Lorenz chaotic map is used for a diffusion process which distorted all pixels of the image. In the statistical security test, means square error (MSE) evaluated error value was greater than the average value of 10000 for all standard images. The value of peak signal to noise (PSNR) was 7.69(dB) for the test image. Moreover, the calculated correlation coefficient values for each direction of the encrypted images was less than zero with a number of pixel change rate (NPCR) higher than 99%. During the security test, the entropy values were more than 7.9 for each grey channel which is almost equal to the ideal value of 8 for an 8-bit system. Numerous security tests and low computational complexity tests validate the security, robustness, and real-time implementation of the presented scheme
