We conducted this study to assess the prevalence of plagiarism and to shed light on some dark aspects of this issue. The main objectives included to find out the etiology, prevalence, and detection of various forms plagiarism.

In this Cross-sectional study we used a questionnaire, face-to-face interview, analyzing the present notifications and codes, websites, and literature review. The current study was conducted throughout Iran from 2017-2018. Those associated with scientific journalism, academic staffs, and authors were interviewed or asked to fill out a prepared questionnaire.

Nine hundred seventy nine questionnaires were circulated. Out of this 706 (72.1%) were completed and returned. Those with a master degree were most cooperative in filling out the questionnaires (36.4%); followed by Assistant Professors (29.6%). About 74.1% of respondents, had not participated in any educational workshops on plagiarism (

<0.001) while 10.8% had not heard anything about plagiarism (

<0.001). As regards cacademic staff and students to publish e more papers regardless of their quality to meet some of the academic requirements. Considering the high rank of Iran in terms of scientific growth worldwide, it is expected from the regulatory authorities to monitor all aspects of scientific misconducts in medical journalism.

To study the prevalence of stroke and associated risk factors in Khyber Pakhtunkhwa (KP) province of Pakistan.

This study was a part of cross-sectional KP Integrated Population Health Survey 2016-17 conducted on population aging ≥18 years at 24 districts of KP. Primary (n=1061) and secondary sampling units (n=15724) were developed, based on urban/rural and socio-economic status. Each primary-unit comprised of 250-300 households. Sample was selected through a multi-staged stratified systematic cluster sampling technique by taking every 16

household per rural and every 12

household per urban-unit. Tubacin A validated "

for identification of stroke patients in community was used along with demographics and potential risk factors.

Among the 15724 randomly selected households, 22500 participants (51.4% females; 74.6% rural areas, mean age 42±12.6 years) were interviewed. Stroke was identified in 271 cases (137 males, 134 females; Mean age=43.39±0.85 years) and prevalence of stroke was 1.2% (1200 per 100,000 population). Obesity/overweight (38.8%), hypertension (21.8%), smoking (6.6%) and known diabetes mellitus (5.9%) were the common associated risk factors of stroke. Age groups >60 years (adjusted OR=1.68; 95% CI 1.05-2.68); urban area (adjusted OR=1.68; 95% CI 1.29-2.19); unemployment (adjusted OR=3.78; 95% CI 2.49-5.73) and lower formal (primary) education (adjusted OR 2.18; 95% CI 1.30-3.64) were significantly associated with stroke (p <0.05).

Prevalence of stroke is 1.2% in the province of KP. Obesity, hypertension, smoking and Diabetes Mellitus are the common associated risk factors of stroke. Higher age, urban area, unemployment and lower formal education are significantly associated with stroke.

Analyzing the RBC damage in microfiltration is important in the sense that it can quantify the sensitivity of human erythrocytes to mechanical hemolysis while they undergo high shear rate and high deformation. Here, the numerical simulations are carried out via lattice Boltzmann method and spring connected network (SN) coupled by an immersed boundary method. To predict the RBC sublytic damage, a sub-cellular damage model derived from molecular dynamic simulations is incorporated in the cellular solver. In the proposed algorithm, the local RBC strain distribution calculated by the cellular solver is used to obtain the pore radius on the RBC membrane. Index of hemolysis (IH) is calculated by resorting to the resulting pore radius and solving a diffusion equation considering the effects of stan estimate the hemolysis in a wide range of filtration pressure and sieve pore size with reasonable accuracy.We analyze how staying at home during the COVID-19 pandemic affects the rates of domestic violence in the U.S. Using police dispatch and crime data from 36 police and sheriff's departments and mobile device tracking data, we find that reported incidents of domestic violence increase as more people stay at home. Specifically, we estimate that staying at home due to COVID-19 increased domestic violence by over 5% on average from March 13 to May 24, 2020. This is consistent with a theory of exposure reduction, where victims and abusers stuck at home are more likely to fight.Exploitation of biomolecular and biomimetic components on solid surfaces gain increasing importance for the design of stable functional platforms. The present study performed by quartz crystal microbalance with dissipation monitoring (QCM-D) reports on the formation of planar hybrid lipid/polymer membranes anchored to a crystalline surface (S-) layer protein lattice. In this approach, hybrid lipid/polymer vesicles were chemically bound to the S-layer protein lattice. Subsequently, to form a hybrid planar layer rupture and fusion was triggered either by (1) β- diketone - europium ion complex formation or (2) successive application of calcium ions, lowering the pH from 9 to 4, and the detergent CHAPS. As determined by QCM-D, method 1 resulted for a polymer content of 5% in a planar membrane with some imbedded intact vesicles, whereas method 2 succeeded in planar hybrid membranes with a polymer content of even up to 70%. These results provide evidence for the effective formation of planar lipid/polymer membranes varying in their composition on an S-layer protein lattice.[This corrects the article DOI 10.1093/biosci/biaa072.].The first case of a myxoid liposarcoma metastatic to the tongue of a 78-year-old male patient with primary scrotal liposarcoma for the past seven years is reported. The patient presented with a firm exophytic mass of the left dorsal surface of the tongue, sized 4 to 4.5 cm, with oedema and bleeding. Myxoid liposarcoma is a malignancy with relatively good prognosis and low metastatic rate but high local recurrence. This is the second case report recorded of a metastatic liposarcoma to the oral cavity. Clinical and imaging considerations, as well pathological details concerning the myxoid liposarcoma, are described.Juvenile xanthogranuloma (JXG) is a rare non-Langerhans cell tumour usually diagnosed during infancy. The lesion is typically located in the skin; however, extracutaneous lesions have been described. The symptoms vary depending on the location and size of the lesion. Presented here is a case of 13-year-old girl with this type of tumour located within the bronchus. She reported chest discomfort, difficulty breathing, and cough. A month prior to admission she had suffered from a respiratory tract infection. Prolonged surgical treatment was required due to the tumour's atypical location and recurrence of the tumour following initial resection. Isolated pulmonary JXG is an extremely rare finding, which requires accurate diagnosis and careful planning of therapeutic treatment. Severe pulmonary symptoms, inconclusive histopathological examination, malignancy risk, and large tumour size are indications for radical surgical resection of the tumour. Non-surgical treatment with chemotherapy is useful in cases of inoperable tumours.

Myasthenia gravis (MG) is a relatively uncommon neuromuscular disease. The thymus plays an important role in the pathogenesis of MG, with 70% of patients presenting with thymic follicular hyperplasia and 20% presenting with thymoma. This study aimed to characterize magnetic resonance (MR) images of thymomas in patients with MG, associated with various stages and types.

A prospective study was performed in 46 MG patients with thymoma, who underwent surgery between August 2014 and September 2018, in Vietnam. Differences in MR imaging (MRI) images, according to type and stage, were assessed by the χ

test or Fisher's exact test and Student's

-test. A

-value < 0.05 was considered significant.

The proportions of each type of thymomas found to be invasive were 28.6%, 61.1%, 66.7%, 90.9%, and 100%, for type A, AB, B1, B2, and B3 thymomas, respectively. Heterogeneous signal intensities on T1- and T2-weighted images, necrosis, and cysts were more commonly observed in high-risk thymomas than in low-risk thymomas. Non-invasive thymomas were more likely to display smooth margins than invasive thymomas (

< 0.05). Only 16.7% of invasive thymomas were detected in MR findings.

Only a few characteristic MRI features could be used to differentiate thymomas by stage or type.

HOXB8 is a protein that was found to promote cancer proliferation and invasion. ILK is a protein kinase which has a role in carcinogenesis. FAT4 is a tumor homologue that has a role in EMT and autophagy regulation.

To identify expression of Human HOXB8, Integrin-linked kinase (ILK1) and FAT homolog 4 (FAT4) in colorectal cancer (CRC) correlating their expression with pathological, prognostic and clinical parameters of CRC.

We assessed the expression of HOXB8, ILK and FAT4 in fifty CRC patients and ten samples from nearby non-neoplastic colonic mucosa using immunohistochemistry.

The expression of HOXB8 and ILK in CRC was positively associated with high tumor grade, advanced tumor stage, lymph node involvement (

< 0.001), occurrence of distant metastases (

= 0.003 and 0.024 respectively), higher incidence of tumor recurrence (

= 0.03,

< 0.001 respectively), worse survival rates (

= 0.038 and 0.003 respectively). The expression of FAT4 in CRC was correlated with lower grade, early stage of the tumor, absence of lymph node involvement (

< 0.001) and lack of distant metastases (

= 0.011). High FAT4 expression was associated with absence of tumor recurrence (

< 0.001) and favorable survival rates (

< 0.001 and 0.003).

High immunohistochemical expression of HOXB8 and ILK in addition to low immunohistochemical expression of FAT4 was associated with unfavorable prognostic and pathological parameters of CRC.

Concurrent chemoradiotherapy (CTRT) remains one of the treatment options in patients with muscle invasive bladder cancer (MIBC) unwilling/unsuitable for radical surgery. We evaluated the role of volumetric modulated arc therapy (VMAT) in MIBC patients treated with definitive CTRT.

25 patients of histologically proven transitional cell MIBC (T2-T4a, N0, M0) unwilling/unsuitable for radical surgery (after maximal transurethral resection of bladder tumour) were recruited in this prospective study. link2 Primary clinical target volume (CTV) consisted of the gross tumour and whole bladder. Primary planning target volume (PTV) and nodal PTV were prescribed 60 Gy and 54 Gy (both in 30 fractions). Concurrent chemotherapy was cisplatin (40 mg/m

) weekly. link3 Acute toxicities were assessed as per Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Survival estimates were done from the date of registration using the Kaplan-Meier method.

Median age was 70 years (37-80 years). Median overall treatment time was 45 days (44-51).
