Assessment of Framingham Risk score and Serum Leptin in Patients with Skin Tag

Skin tags are common dermatological lesions that have been linked to metabolic syndrome, which includes diabetes, obesity, and hypertension, as well as cardiovascular disease. Increased adipose deposition and serum leptin levels may be associated with skin tags (STs). The relationship between serum lipid profile and serum leptin levels in patients with skin tags and the Framingham risk score was investigated. The Framingham risk score (FRS) is a method to calculate the likelihood of getting cardiovascular disease (CVD) during a 10-year period (CVD). The current study was carried out on 60 participants; 30 patients with STs and 30 apparently healthy as controls. Serum lipid profile and serum leptin were measured. There was Statistically significant difference of serum leptin level between skin tag (22.6±16.4 ng/ml) group and control (13.23±10.14 ng/ml) and cholesterol also showing significant difference between skin tag disease group (183.3±37.12 mg/dl) and the control group (155.6±21.86 mg/dl). Other parameters Low Density Lipoprotein (LDL), Triglycerides (TG) and non-High-Density Lipoprotein, cholesterol (non-HDL) show no significant difference between the two groups. An assessment was performed to differentiate between skin tag and Framingham risk score. It was found that 70% of patients are in high and moderate risk group. The present study found association between skin tag patients and Framingham risk score.

Effect of different levels of cycocel on the vegetative growth and flowering of Gardenia jasminoides J. Ellis plant

: Gardenia is one of the important indoor plants in the flower market. This study was conducted to evaluate the effect of different concentrations of cycocel (0, 1500, 3000, and 4500 ppm) on vegetative growth, flowering and pigments content of Gardenia jasminoides J. Ellis plant. Treatment with high concentrations of cycocel (4500ppm) led to a significant decrease in plant height and a reduction of fresh and dry weight, while it increased branching in contrast to low concentrations and control. Moreover, spraying with cycocel at rates of 4500 and 3000 ppm enhanced early flowering. The highest values of number of flowers were especially by spraying plants with 4500 ppm of cycocel, followed by plants treated with cycocel at a rate of 3000 ppm. Accordingly, the highest value of fresh and dry weights of flowers was due to treatment with cycocel moderate rate of 3000 ppm. Furthermore, the contents of chlorophyll and carotenoids were upgraded in plants sprayed with cycocel at all concentrations used.
Multithread Hydrodynamic Modeling of a Solar Flare

Past hydrodynamic simulations have been able to reproduce the high temperatures and densities characteristic of solar flares. These simulations, however, have not been able to account for the slow decay of the observed flare emission or the absence of blueshifts in high spectral resolution line profiles. Recent work has suggested that modeling a flare as a sequence of independently heated threads instead of as a single loop may resolve the discrepancies between the simulations and observations. In this paper, we present a method for computing multithread, time-dependent hydrodynamic simulations of solar flares and apply it to observations of the Masuda flare of 1992 January 13. We show that it is possible to reproduce the temporal evolution of high temperature thermal flare plasma observed with the instruments on the GOES and Yohkoh satellites. The results from these simulations suggest that the heating timescale for a individual thread is on the order of 200 s. Significantly shorter heating timescales (20 s) lead to very high temperatures and are inconsistent with the emission observed by Yohkoh.
Electrochemically assembled p-type Bi2Te3 nanowire arrays

Polycrystalline Bi2Te3 nanowires with diameter about 50 nm have been assembled into the nanopores of alumina template by electrodeposition in the solution containing Bi3+ and HTeO2+ with porous alumina template as a cathode. X-ray photoelectron spectroscopy, high-resolution electron microscopy, and selected area electron diffraction investigations indicate that the nanowires are polycrystalline Bi2Te3 with hexagonal structure. Transmission electron microscopy and environmental scanning electron microscopy are used to characterize the morphology of the Bi2Te3 nanowire arrays. The performance measurements verified that the Seebeck coefficient of p-type Bi2Te3 nanowire arrays prepared in our lab was 270 μV/K at 306 K, which is larger than that of bulk Bi2Te3 thermoelectric materials. The temperature dependence of the resistance of the nanowire arrays was also measured, and it showed a semiconductive characteristic.
FRAME-BASED STEREOTACTIC SURGERY IN THALAMIC LESIONS

Background: Stereotactic surgery is recommended over dramatic excision for the management of thalamic malignancies because the thalamus is a vital structure surrounded by essential white matter pathways. Aim of the work: Assessment of the benefits and safety of the frame-based stereotactic surgery in thalamic lesions. Patients and Methods: Retrospective study conducted on 15 patients suffering from different thalamic lesions, recruited from Neurosurgery Department, Al-Azhar University and Ministry of Health Hospitals over the period from 2016 to 2021. Result: Patients mean age were 39.53 ± 15.58 years old. 40% of them were males and 60% were females. Majority (81.8%) of patients presenting with headache preoperatively had improved postoperatively, no statistically significant difference. patients with Dysphasia, 44.4% improved as a result of the operation. Regarding patients presenting with symptoms of increased intracranial pressure; the 3 patients who presented with repeated vomiting had improved. For consciousness level, 50% of patients presenting with DCL had improved. Patients presenting with bilateral hyperreflexia, showing clinical improvement in 100% of patients. Pneumocephalus was the most common complications met, which was prevalent in 66.7% of patients followed by intralesional hematoma which performed 20% of the population. Obstructive hydrocephalus came into the least order. Conclusion: Thalamic lesions treated by frame-based stereotactic surgery showed postoperative improvement of headache, symptoms of increased intracranial pressure, and bilateral hyper-reflexia with no statistically significant difference between pre. and post-operative symptoms, on the other side no improvement were documented regarding unilateral hyperreflexia, Right and left hemiparesis, ataxia and vision.
On hyperKahler singularities

Using a geometric realization of the SU(2)R symmetry and a procedure of factorisation of the gauge and SU(2)R charges, we study the small instanton singularities of the Higgs branch of supersymmetric U(1) r gauge theories with eight supercharges. We derive new solutions for the moduli space of vacua preserving manifestly the eight supercharges. In particular, we obtain an extension of the ordinary ADE singularities for hyperKahler manifolds and show that the classical moduli space of vacua is in general given by cotangent bundles of compact weighted projective spaces.
MmWave Physical Layer Network Modeling and Planning for Fixed Wireless Access Applications

The large bandwidths that are available at millimeter-wave frequencies enable fixed wireless access (FWA) applications, in which fixed point-to-point wireless links are used to provide internet connectivity. In FWA networks, a wireless mesh is created and data are routed from the customer premises equipment (CPE) towards the point of presence (POP), which is the interface with the wired internet infrastructure. The performance of the wireless links depends on the radio propagation characteristics, as well as the wireless technology that is used. The radio propagation characteristics depend on the environment and on the considered frequency. In this work, we analyzed the network characteristics of FWA networks using radio propagation models for different wireless technologies using millimeter-wave (mmWave) frequencies of 28 GHz, 60 GHz, and 140 GHz. Different scenarios and environments were considered, and the influence of rain, vegetation, and the number of subscribers was investigated. A network planning algorithm is presented that defines a route for each CPE towards the POP based on a predefined location of customer devices and considering the available capacity of the wireless links. Rain does not have a considerable effect on the system capacity. Even though the higher frequencies exhibit a larger path loss, resulting in a lower power of the received signal, the larger bandwidths enable a higher channel capacity.
Effect of Diode laser with and without enamel matrix derivative on periodontal healing of replanted teeth after extended extra-oral dry time (Histological and Immunohistochemical study)

Ismailia, ABSTRACT The aim of the study was to evaluate the effect of enamel matrix derivative and high power diode laser irradiation on healing of periodontal ligament (PDL) of experimentally and replanted upper incisors teeth of albino rats after extended extra oral dry time through histological examination and immunohistochemical detection of fibronectin. Materials and methods: 30 adult male Albino rats divided into three groups, 10 rats each; group I served as controls were no treatment for root surface of extracted incisors before their replantation, group II were root surface treated with enamel matrix derivative (Emdogain) gel, group III were root surface treated with diode laser and Emdogain gel . Five rats of each group were sacrificed four weeks from the beginning of the experiment while the other five rats were sacrificed after eight weeks. The jaws of the upper incisors regions of the sacrificed animals were dissected out for histological examination and immunohistochemical analysis. Results: The histological examination of group I rats showed massive degeneration and loss of orientation in the collagen fibers of PDL of replanted teeth, group II rats revealed signs of PDL regeneration in the form well-defined but unorganized fibers of PDL, while group III rats showed the best regenerative features in the form of well oriented and organized fibers of PDL. Immunohistochemical detection of fibronectin of group I showed negatively to weakly positive reaction. PDL of group II presented moderately positive reaction. While, group III presented strongly positive reaction. Conclusions : Application of Emdogain only to the root surface of replanted teeth has limited inductive effects on the regeneration of PDL cells and fibers while using of Emdogain in combination with diode laser on the root surface leads to better periodontal healing.
A behavioral analysis of Greek strike activity

This work deals with the analysis of Greek strike activity during the period 1975-1994 based on the data collected by the National Statistical Service of Greece. The work is distinguished into two parts as follows: a. For the industry sector, b. For all the sectors. Conventional strike equations are specified and estimated using the data for all strikes and the effects of the explanatory variables are compared. The study includes several explanatory variables, which have been used by many investigators of strikes. To analyze the aforementioned data, the ARIMA procedure was also used to estimate and forecast models using the methods prescribed by Box and Jenkins (1976). The logarithmic transformation of the data has demonstrated a better behavior of the respective models, fact that it was expected since in a previous work, which was presented in the Fourth Statistical Conference of Greece in Patras 1991, the goodness of fit of the data in the lognormal distribution has been proved.
Open Thoracotomy versus Video-Assisted Thoracic Surgery for Bullectomy in Primary Spontaneous Pneumothorax

Background: Spontaneous pneumothorax (SP) remains a significant health problem because of the high recurrence rate during thoracic drainage and conservative treatments. SP can appear under two forms: primary SP occurs in otherwise healthy patients, most commonly in tall, young, lean men, and particularly in those who smoke. Secondary SP occurs as a complication of an underlying lung disease, which most often is chronic obstructive pulmonary disease. Objective: The aim of the study was to compare outcome in patient who undergo thoracoscope and patients who undergo thoracotomy in primary spontaneous pneumothorax. Patients and Methods : This randomized clinical trial study was conducted at Cardiothoracic Surgery Department, Zagazig University Hospitals. We included 30 patients with primary spontaneous pneumothorax in a randomly selected (allocation sealed envelope). Patients were randomly divided into two groups; Group A: 15 cases were subjected to video-assisted thoracic surgery (VATS) Bullectomy in primary spontaneous pneumothorax. Group B: 15 cases were subjected to open thoracotomy in primary spontaneous pneumothorax. Results: This study showed that there was significant difference between both groups regarding to intraoperative blood loss, chest tube duration and hospital stay that was higher in thoracotomy group than VATS group. The complications were higher in open thoracotomy than VATS group but it did not reach significant difference. Also, there was no significant difference regarding to recurrence. Conclusion: VATS is associated with shorter length of hospital stay and less blood loss with no difference of recurrence, and postoperative outcome compared to open thoracotomy in primary spontaneous pneumothorax patients.
Limit on the axion decay constant from the cooling neutron star in Cassiopeia A

The observed rapid cooling of the neutron star (NS) located at the center of the supernova remnant Cassiopeia A (Cas A) can be explained in the minimal NS cooling scenario. This consequence may be changed if there exists an extra cooling source, such as axion emission. In this work, we study the Cas A NS cooling in the presence of axion emission, taking account of the temperature evolution in the whole life of the Cas A NS. We obtain a lower limit on the axion decay constant, $f_a\gtrsim (5-7)\times 10^8$ GeV, if the star has an envelope with a thin carbon layer. This is as strong as existing limits imposed by other astrophysical observations such as SN1987A.
Exploring the Relationship Between Bisphenol A, Iodine and Papillary Thyroid Carcinoma

Bisphenol A, one of the environmental endocrine disrupting chemicals, was shown to have a weak estrogen activity and could disrupt thyroid function to some degree. Iodine, which is the most essential microelement that is used for the synthesis of thyroid hormones in humans, was proven to give rise to thyroid diseases, such as thyroiditis, thyroid nodular goiter, and so on. There are relatively very few studies that have considered the role that both Iodine and Bisphenol A play in the development of papillary thyroid carcinoma. Therefore, this crosssectional observational study was carried out to explore the relationship between Iodine, Bisphenol A and Papillary Thyroid Carcinoma. The study included 113 subjects aged from 20 years to 80 years selected from Qilu Hospital of Shandong University from February 2015 to September 2015 and 65 healthy volunteers residing in Jinan, P.R. China. We compared the differences of the concentrations of Urinary Iodine, Urinary Bisphenol A and Serum Bisphenol A among patients of Papillary Thyroid Carcinoma, nodular goiter and normal population. In the PTC and nodular goiter group, urinary BPA and Iodine concentrations were significantly higher than controls stating that the excretion of Iodine and BPA were increased. Meanwhile 23 patients with papillary thyroid carcinoma (43%) had excessive iodine nutrition compared to only 6 volunteers with excessive iodine intake in the control group (9%). These findings suggest that excessive dietary iodine intake is a risk factor for thyroid cancer. Moreover, the significant association between urinary creatine-adjusted BPA and iodine suggest that they might have a synergistic effect on the thyroid. JCMCTA 2016 ; 27 (2) : 50 - 59
Surgical Management of Cervical Myelopathy Anterior Versus Posterior Approaches

Background: The most prevalent cause of spinal cord impairment is cervical spondylotic myelopathy (CSM). In the older, it is also the primary cause of spinal-cord-related impairment. Spinal cord compression can result from ventral pathologies or from dorsal compression causing progressive disability and impairing the quality of life. Aim of the work: This study aims to compare anterior cervical discectomy and fusion using inter body fusion cages with posterior lamin ectomy in the management of one or multiple level cervical spon dylotic myelopathy. Patients and Methods: 20 patients had cervical spondylotic myelo pathy were identified in our research. There were 16 men and 4 women. Aged from (25 to 70 years) 10 patients operated upon by anterior cervical discectomy and fusion using interbody fusion cages and the other 10 patients were operated upon by posterior laminectomy. Result: 20 patients with cervical spondy lotic myelopathy were identified in our research. 10 patients operated upon by anterior cervical discectomy and fusion using interbody fusion cages and the other 10 patients were operated upon by posterior laminectomy. Conclusion: In this study, there is no significant difference between both groups in terms of myelopathy improvement. Postoperative pain is much less in the anterior group than in the posterior group. The average hospital stay is greater in the posterior group. However, the anterior group patients have nearly double the operative time and increased the risk of reversible dysphagia while the posterior group has more rate of C5 palsy and infection.
Large deviations for compound Markov renewal processes with dependent jump sizes and jump waiting times

In [17] the author considered a compound Markov renewal process ( e SNt) where ((Jn, Sn)) and (( e Jn, e Sn)) are suitable independent Markov additive processes such that (Sn − Sn−1) are positive random variables, and Nt = P n≥1 1Sn≤t. In this paper we present the analogous results for a more general situation where we consider a unique Markov additive process ((Jn, Zn)) in place of ((Jn, Sn)) and (( e Jn, e Sn)), and Zn = ( e
Effect of Some Foliar Spray Treatments on Growth and Yield of Tomatoes

This study was conducted during the two consecutive summer seasons of 2020 and 2021 at the farm of the Faculty Agriculture, Al-Azhar University, Assiut, Egypt to study the effect of some treatments on Thuraya and Princes tomato hybrids. These treatments are garlic at rates 5,10 ml/L and licorice extracts at rates 5,10 ml/L , as well as the concentrations of boron at 2,4 ml/L and calcium 4,8 ml/L beside the control (non-coefficient). All applications were added four times starting after 45 days transplanting at 10 days intervals. Measurements of plant height, number of leaves, number of branches, total chlorophyll content, total soluble solid, average fruit weight per plant, total yield of crop expressed in tons\fed were recorded in this investigation. The data was statistically analysed, and the result shows that there was a significant differentiation in the characteristics between the hybrids, as well as a significant difference between treatments and interaction between them in both seasons. The best treatments used were garlic extract concentration 5 cm per litre, and the average increase in the total yield was estimated at 24.4% compared to control.
The Possible Protective Effect of Vitamin C Against Sildenafil Citrate Affected Liver of Adult and Senile Male Albino Rats (Light and Electron Microscopic Study)

Background: Erectile dysfunction (ED) affects a growing number of men in the USA and abroad. Phosphodiesterase 5 inhibitors as sildenafil citrate (SC) are used to treat erectile dysfunction and pulmonary hypertension. SC is mainly metabolized in the liver. Vitamin C is an antioxidant that has hepatoprotective effects. Aim of the study: To reveal the histological alterations in liver of adult and senile rats treated with SC, and to explore the impact of vitamin C co-treatment. Materials and Methods: Study was done at the House of Animals, Pharmacy Faculty, Al-Azhar University between July, and September 2021. Sixty male albino rats were used (divided in equal pattern into 5 groups); Each one was subdivided to two equal subgroups: adult and senile rats. They received drugs through oro-gastric feeding tube. Group I: received water 10 ml/ kg/ d for 30 days; group II: received 10 mg /kg /d of SC for 30 days; group III: received 26mg /d of vitamin C one hour prior to 10 mg /kg /d of SC for 30 days; group IV: received 26mg/d of vitamin C for 30 days; group V: received 10 mg /kg /d of SC for 30 days, then left one month. Then, the animals were anesthetized, and tissues of liver were proceeded and microscopically examined. Results: Histological changes were more severe in senile rats and significantly improved with vitamin C co-treatment and minimally improved in withdrawal group. Conclusion: This study revealed that vitamin C might have a protective effect against sildenafil citrate induced hepatic injury.
Risk factors for hospital-acquired pneumonia in hip fracture patients: a systematic review and meta-analysis

Objective This study aimed to systematically assess the incidence and risk factors for hospital-acquired pneumonia (HAP) in hip fracture patients by meta-analysis. Methods Systematically searched four English databases (PubMed, EMBASE, The Cochrane Library, and Web Of Science) and four Chinese databases (CNKI, CQVIP, Sinomed, and WAN FANG) from inception until 20 November 2023. All studies involving risk factors of HAP in patients with hip fractures were considered. Newcastle-Ottawa Scale was used to evaluate the quality of the included studies. The results were presented with the pooled odds ratio (OR) and 95% confidence interval (95% CI). Results Of 35 articles (337,818 patients) included in this study, the incidence of HAP was 89 per 1000 cases. Twenty-three risk factors were eventually involved in the meta-analysis, and 21 risk factors were significant. Our study has identified four significant risk factors (advanced age, preoperative time, COPD, and hypoalbuminemia) associated with HAP, as follows: Advanced age as a continuous variable (OR 1.07, 95% CI 1.05–1.10), Advanced age > 70 years (OR 2.34, 95% CI 1.77–3.09), Advanced age > 80 years (OR 2.98, 95% CI 2.06–4.31), Chronic obstructive pulmonary disease (COPD) (OR 3.44, 95% CI 2.83–4.19), Time from injury to operation as a continuous variable (OR 1.09, 95% CI 1.07–1.12), Time from injury to operation ≥48 h (OR 3.59, 95% CI 2.88–4.48), Hypoalbuminemia < 3.0 g/dL (OR 3.03, 95% CI 1.93–4.73), and Hypoalbuminemia < 3.5 g/dL (OR 2.68, 95% CI 2.15–3.36). However, it is important to note that all the studies included in our research were retrospective in nature, which introduces certain limitations to the level of evidence and the ability to establish causal inferences. Discussion Patients who have suffered hip fractures are at an increased risk of developing postoperative hospital-acquired pneumonia, which can lead to prolonged hospital stays and adverse clinical outcomes. Consequently, the identification of these risk factors offers novel insights and methodologies for healthcare professionals in terms of both prevention and treatment.
