4Optical and electrical properties of crystalline indium tin oxide thin film deposited by vacuum evaporation technique显示文摘Indium tin oxide(ITO) thin film was deposited on glass substrate by means of vacuum evaporation technique and annealed at 200 ℃, 300℃ and 400 ℃ in air for 1 h. The characterization and properties of the deposited film samples were analyzed by X-ray diffraction(XRD), scanning electron microscopy(SEM), and UV-VIS-NIR spectroscopy techniques. From the XRD patterns, it was found that the deposited thin film was of crystalline at an annealing temperature of 400℃. The crystalline phase was indexed as cubic structure with lattice constant and crystallite size of 0.511 nm and 40 nm, respectively. The SEM images showed that the films exhibited uniform surface morphology with well-defined spherical grains. The optical transmittance of ITO thin film annealed at 400 ℃ was improved from 44% to 84% in the wavelength range from 250 nm to 2 100 nm and an optical band gap was measured as 3.86 e V. Hall effect measurement was used to measure the resistivity and conductivity of the prepared film.Md.Mottaleb Hosen A.K.M.Atique Ullah Md.Mahbubul Haque S.M.Abdur Rahim K.M.Abdus Sobahan M.N.I.Khan 2019Optoelectronics Letters2019,15,5:1
5Trends of obesity and overweight among children and adolescentsin China显示文摘Background Recent decades have shown a rapid increase in the prevalence of overweight and obesity among Chinese children based on several national surveys.Restrictions due to the coronavirus disease 2019 outbreak have worsened its epidemiol-ogy.This review updates the trends in the prevalence of overweight and obesity among Chinese children and adolescents and analyzes the underlying reasons to provide evidence for better policy making.Methods Studies published in English and Chinese were retrieved from PubMed,Google Scholar,China National Knowl-edge Infrastructure andWanfang.Results The prevalence of overweight and obesity has been increasing for decades and varies with age,sex and geography but is more pronounced in primary school students.The increase in obesity in boys appeared to be slower,whereas that in girls showed a declining trend.The northern areas of China have persistently maintained the highest levels of obesity with a stable trend in recent years.Meanwhile,the prevalence in eastern regions has dramatically increased.Notably,the overall prevalence of obesity in children has shown a stabilizing trend in recent years.However,the occurrence of obesity-related metabolic diseases increased.The effect of migrants floating into east-coast cities should not be neglected.Conclusions The high prevalence of overweight and obesity among Chinese children and adolescents persists but with vary-ing patterns.Obesity-related metabolic diseases occur more frequently despite a stable trend of obesity.Multiple factors are responsible for the changing prevalence.Thus,comprehensive and flexible policies are needed to effectively manage and prevent the burden of obesity and its related complications.Ye Hong Rahim Ullah Jian‑Bing Wang Jun‑Fen Fu 2023World Journal of Pediatrics2023,19,12:1
6First report on molecular characterization of Leishmania species from cutaneous leishmaniasis patients in southern Khyber Pakhtunkhwa province of Pakistan显示文摘Objective: To report presence of Leishmania major in Khyber Pakhtunkhwa of Pakistan, where cutaneous leishmaniasis(CL) is endemic and was thought to be caused by Leishmania tropica only. Methods: Biopsy samples from 432 CL suspected patients were collected from 3 southern districts of Khyber Pakhtunkhwa during years 2011–2016. Microscopy on Giemsa stained slides were done followed by amplification of the ribosomal internal transcribed spacer 1 gene. Results: Leishmania amastigotes were detected by microscopy in 308 of 432 samples(71.3%) while 374 out of 432 samples(86.6%) were positive by ribosomal internal transcribed spacer 1 PCR. Subsequent restriction fragment length polymorphism confirmed Leishmania tropica in 351 and Leishmania major in 6 biopsy samples. Conclusions: This study is the first molecular characterization of Leishmania species in southern Khyber Pakhtunkhwa. It confirmed the previous assumptions that anthroponotic CL is the major CL form present in Khyber Pakhtunkhwa province. Furthermore, this is the first report of Leishmania major from a classical anthroponotic CL endemic focus identified in rural areas of Kohat district in southern Khyber Pakhtunkhwa.Mubbashir Hussain Shahzad Munir Sultan Ayaz Bahar Ullah Khattak Taj Ali Khan Niaz Muhammad Muhammad Anees Hazir Rahman Muhammad Qasim Muhammad Ameen Jamal Irfan Ahmed Kashif Rahim Humaira Mazhar Noha Watanay Mohamed Kasbari 2017Asian Pacific Journal of Tropical Medicine2017,10,7:1

9Secure Transmission of Compressed Medical Image Sequences on Communication Networks Using Motion Vector Watermarking显示文摘Medical imaging plays a key role within modern hospital management systems for diagnostic purposes.Compression methodologies are extensively employed to mitigate storage demands and enhance transmission speed,all while upholding image quality.Moreover,an increasing number of hospitals are embracing cloud computing for patient data storage,necessitating meticulous scrutiny of server security and privacy protocols.Nevertheless,considering the widespread availability of multimedia tools,the preservation of digital data integrity surpasses the significance of compression alone.In response to this concern,we propose a secure storage and transmission solution for compressed medical image sequences,such as ultrasound images,utilizing a motion vector watermarking scheme.The watermark is generated employing an error-correcting code known as Bose-Chaudhuri-Hocquenghem(BCH)and is subsequently embedded into the compressed sequence via block-based motion vectors.In the process of watermark embedding,motion vectors are selected based on their magnitude and phase angle.When embedding watermarks,no specific spatial area,such as a region of interest(ROI),is used in the images.The embedding of watermark bits is dependent on motion vectors.Although reversible watermarking allows the restoration of the original image sequences,we use the irreversible watermarking method.The reason for this is that the use of reversible watermarks may impede the claims of ownership and legal rights.The restoration of original data or images may call into question ownership or other legal claims.The peak signal-to-noise ratio(PSNR)and structural similarity index(SSIM)serve as metrics for evaluating the watermarked image quality.Across all images,the PSNR value exceeds 46 dB,and the SSIM value exceeds 0.92.Experimental results substantiate the efficacy of the proposed technique in preserving data integrity.Rafi Ullah Mohd Hilmi bin Hasan Sultan Daud Khan Mussadiq Abdul Rahim 2024Computers, Materials & Continua2024,78,3:0
10Molecular detection of Leishmania species in human and animals from cutaneous leishmaniasis endemic areas of Waziristan, Khyber Pakhtunkhwa, Pakistan显示文摘Objectives: To detect Leishmania species in human patients, animal reservoirs and Phlebotomus sandflies in Waziristan, Pakistan. Methods: Tissue smears and aspirates from 448 cutaneous leishmaniasis(CL) suspected patients were analyzed. To sort out role of the reservoir hosts, skin scrapings, spleen and liver samples from 104 rodents were collected. Furthermore, buffy coat samples were obtained from 60 domestic animals. Sandflies were also trapped. All human, animals and sandfly samples were tested by microscopy, kinetoplastic PCR and internal transcribed spacer 1(ITS1) PCR followed by restriction fragment length polymorphism for detection of Leishmania species. Results: An overall prevalence of 3.83% and 5.21% through microscopy and ITS1 PCR respectively was found. However, the statistically non-significant correlation was found between area, gender, and number of lesions. The presence of rodents, sandflies, domestic animals and internally displaced people increased the risk of CL. Using ITS1-PCR-RFLP, Leishmania tropica(L. tropica) was confirmed in 106 samples while 25 of the isolates were diagnosed as Leishmania major(L. major). Similarly, 3/104 rodents were positive for L. major and 14 pools of DNA samples containing Phlebotomus sergenti sandflies were positive for L. tropica. None of samples from domestic animals were positive for leishmaniasis. Conclusions: In the present study, L. tropica and L. major are found to be the main causative agents of CL in study area. Movement of internally displaced people from CL endemic areas presents a risk for nearby CL free areas. To the best of our knowledge, we report for the first time L. major infection in rodents(Rattus rattus) and L. tropica in Phlebotomus sergenti sandflies trapped in Waziristan, Pakistan.Mubashir Hussain Shahzad Munir Abdullah Jalal Taj Ali Khan Niaz Muhammad Bahar Ullah Khattak Abdullah Khan Irfan Ahmed Zulqarnain Baloch Nawaz Haider Bashir Muhammad Ameen Jamal Kashif Rahim Humaira Mazhar Maira Riaz Noha Watany 2018Asian Pacific Journal of Tropical Medicine2018,11,8:0
