Abstract
The use of visible photon fluxes to influence catalytic reactions on metal nanoparticle surfaces has attracted attention based on observations of reaction mechanisms and selectivity not observed under equilibrium heating. These observations suggest that photon fluxes can selectively impact the rates of certain elementary steps, creating nonequilibrium energy distributions among various reaction pathways. However, quantitative studies validating these hypotheses on metal nanoparticle surfaces are lacking. We examine the influence of continuous wave visible photon fluxes on the CO desorption rates from 1 to 2 nm diameter Pt and Pd nanoparticle surfaces supported on γ-Al2O3. Temperature-programmed desorption measurements quantified via diffuse reflectance infrared Fourier transform spectroscopy demonstrate that visible photon fluxes significantly enhanced the rate of CO desorption from Pt nanoparticles in a wavelength-dependent manner. 440 nm photons most efficiently promoted CO desorption from Pt nanoparticle surfaces, aligning with the excitation energy for the interfacial electronic transition within the Pt-CO bond. Conversely, visible photon fluxes had no measurable influence on CO desorption rates from Pd nanoparticle surfaces after accounting for photon-induced heating. Density functional theory calculations demonstrate that the Pt-CO bond exhibits a narrower LUMO resonance, stronger coupling between the photoexcitation and forces induced on the metal-C bond, and vibrational energy dissipation that more effectively couples to desorption as compared to Pd-CO. These results demonstrate the specificity photons provide in facilitating chemical reactions on metal nanoparticle surfaces and substantiate the idea that photon fluxes can steer processes and outcomes of catalytic reactions in ways not achievable by equilibrium heating.

Abstract
Abstract
Introduction/Objective
Secondary hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome of immune hyperactivation and dysregulation that has been observed in some malignancies. In HLH, natural killer (NK) cells and cytotoxic T-cells fail to control activated macrophages, leading to cytokine-mediated tissue injury and multiorgan failure. Persistent tumor antigenic stimulation and cytokine hypersecretion can trigger HLH. Diffuse large B- cell lymphoma (DLBCL) is uncommonly associated with HLH.
Methods/Case Report
A 50-year-old woman presented with daily fevers and malaise of one-month duration. Imaging showed marked hepatosplenomegaly with no lymphadenopathy. Laboratory studies were significant for pancytopenia (WBC: 3.8 K/µL, Hb: 6.8 g/dL, Plt: 74 K/µL), hypertriglyceridemia (330 mg/dL), hyperferritinemia (1460 ng/mL), and elevated soluble interleukin-2 receptor (CD25) (42351.5 pg/mL). These findings, along with NK cell activity level (not obtained in this case), fever, splenomegaly and hemophagocytosis (bone marrow, spleen or lymph nodes) represent the eight diagnostic criteria by Histiocyte Society HLH-2004. A splenic biopsy showed a nodular proliferation of medium-to-large neoplastic lymphocytes with CD20, PAX5, BCL6, MUM1, BCL2, CD5 (dim) and CD10 (dim) expression and negative for cyclin D1 and p53. CD21 did not highlight any dendritic cell meshwork. The bone marrow biopsy provided similar results. Overall, these findings were consistent with a DLBCL, germinal center subtype. Rearrangements of MYC, BCL2 or BCL6 genes were not detected. Although hemophagocytosis was not noted in the bone marrow or spleen, the patient met six of the eight HLH-2004 criteria (minimum five are required). The H-score was 174 reflecting up to 70% probability of HLH. Treatment with daily intravenous dexamethasone 10 mg/m2 was initiated as a temporizing measure prior to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy which resulted in complete remission.
Results (if a Case Study enter NA)
NA
Conclusion
Physicians should be cognizant of secondary HLH as a rare complication of DLBCL. Prompt initiation of the appropriate therapy could result in rapid and complete resolution.

Abstract
Abstract
Introduction/Objective
Microsecretory adenocarcinoma (MCA) is a recently recognized malignancy of the salivary glands that almost exclusively arises in the oral cavity with the hard palate being the most common site. To our knowledge, there are only 24 cases of MCA reported in the English literature, all of which displayed a notably consistent histology and immunohistochemical profile. MCA is a low-grade and well-circumscribed tumor with subtle infiltration into the surrounding soft tissue. A cellular fibromyxoid stroma containing microcystic tubules with abundant intraluminal basophilic secretions are distinct histologic features. Immunohistochemically, MCA is positive for S100, p63, and SOX10, and lacks expression of p40, calponin, and mammaglobin. MEF2C-SS18 fusion gene defines MCA molecularly.
Methods/Case Report
A 43-year-old woman underwent a biopsy of a sessile, nontender, papillomatous, flesh-colored lesion of the right hard palate. No evident bone erosion or cervical lymphadenopathy were detected on imaging. Histology showed stratified squamous epithelium with focal pseudoepitheliomatous hyperplasia and an underlying salivary gland neoplasm consisting of microcystic tubules that were embedded in a scant myxoid stroma. Immunohistochemically, the neoplastic cells expressed S100, SOX10, AE1/AE3, CAM5.2, and p63, while negative for p40 and mammaglobin. In light of the histology and immunohistochemistry, a diagnosis of microsecretory adenocarcinoma was rendered. Right palatectomy and partial maxillectomy was subsequently performed. The specimen was notable for a 0.8 cm well-circumscribed, white-tan, submucosal solid mass that displayed an identical histology to the biopsy and involved the deep margin. No perineural or lymphovascular invasion was identified.
Surveillance exam and MRI show no recurrence after one year.
Results (if a Case Study enter NA)
NA
Conclusion
MCA is a newly defined entity that has an indolent clinical course with no reports of metastasis or recurrence after complete surgical resection. It is crucial to distinguish MCA from malignancies it resembles morphologically to avoid aggressive therapy. In challenging cases, molecular analysis can help the pathologist achieve the final diagnosis.

Abstract
Abstract
Introduction/Objective
When exposed to antibiotics or a host immune response, Gram-negative bacilli grow with inhibited septation producing long continuous cells; a phenomenon known as filamentation.
Methods/Case Report
We present a case of a 68-year-old man with quadriplegia, which was caused by the right vertebral artery dissection and subarachnoid hemorrhage requiring an emergent posterior inferior cerebellar artery direct bypass surgery. Lung lower lobe infiltrates were noted 3 days after the surgery. A bronchial wash culture was negative for growth, and a sputum specimen grew Serratia marcescens. The patient was treated with piperacillin/tazobactam, vancomycin, cefepime, cefazolin. After the surgery, he suddenly developed severe cerebral vasospasm of the posterior circulation with cerebellar strokes requiring emergent posterior fossa decompression. He remained on ventricular drainage by external ventricular drainage. After two days, the patient's cerebrospinal fluid (CSF) was sent for evaluation, on which a high segmented neutrophil count of 35% and Gram-negative filamentous organisms with occasional swellings were noted. Multi-drug resistant Serratia marcescens was isolated from the CSF specimen four days later. Neurosurgical procedures were reported to be highly associated with S. marcescens meningitis. The filamentous organisms noted on Gram-stained direct smear most likely represented Gram-negative S. marcescens with filamentation due to administration of sub-inhibitory concentrations of antibiotics.
Results (if a Case Study enter NA)
NA.
Conclusion
Gram-negative bacilli can develop abnormal morphology including elongation, swelling, and filamentation due to stress or sub-inhibitory antibiotic exposure, and it is important for microbiologists and pathologists to be aware of this phenomenon to avoid misinterpretation that may lead to inappropriate treatment.

Abstract
Abstract
Introduction/Objective
Intravascular large B-cell lymphoma (IVLBCL) is a rare, clinically aggressive lymphoma defined by the proliferation of atypical lymphoma cells in the lumen of all sized blood vessels, particularly capillaries. The reasons for this unusual neoplastic cell proliferation are still only partially understood. IVLBCL is considered stage IV lymphoma and manifests with a variety of nonspecific signs and symptoms. Patients with IVLBCL usually do not present with lymphadenopathy. The tumor cells invade the blood vessels of multiple organs such as the central nervous system, skin, lungs, kidneys, and bone marrow. Common presenting symptoms are based on the organ affected and include mental status changes and fever of unknown origin. Although immunochemotherapy has significantly improved the often-poor prognosis of this kind of lymphoma, a large percentage of patients relapse.
Methods/Case Report
We present a 63-year-old man who had been diagnosed with diffuse large B cell lymphoma in the bone marrow in March 2021 and was in remission state after completing six cycles of chemotherapy. There was no abnormal FDG uptake on a post-chemotherapy PET/CT scan. Patient presented to the ER two months later with fever and dyspnea. The entire workup was completed and showed pancytopenia and elevated ESR. While chest CT scan did not show lymphadenopathy or lesions, PET/CT scans revealed a widespread increase in FDG uptake in both the lungs and spleen. Lung biopsy revealed large atypical cells within alveolar septae and vessels.
Immunohistochemical stains demonstrated that these cells were positive for CD20 and PAX-5 and had high proliferation rate based on Ki67.
Results (if a Case Study enter NA)
NA
Conclusion
IVLBCL has a low incidence rate with non-specific clinical presentation. The diagnosis can be easily missed in both clinical, radiological and the corresponding histopathological findings . Radiological finding and CT scan are not sensitive enough and may miss the lesion. Even though the PET/CT scan is more sensitive, the definitive diagnosis of IVLBCL relies mainly on histopathology and immunohistochemistry, at which point awareness of this entity by the Pathologist is most necessary.

Abstract
Abstract
Introduction/Objective
Adrenal cortical carcinoma (ACC) is a rare neoplasm with oncocytic, myxoid, and sarcomatoid variants. Sarcomatoid is the least common variant. To our knowledge, there are only 23 cases of sarcomatoid ACC reported in the English literature. Typically, ACC’s express SF1, Melan A, inhibin, and synaptophysin. It has been reported that the sarcomatoid component does not express the aforementioned immunomarkers; however, it can display mutational expression of p53 and β-catenin.
Methods/Case Report
A 77-year-old man was incidentally found to have a left adrenal gland mass. Hormone levels were unremarkable, and adrenalectomy was performed. Gross examination of the specimen revealed a 4.5 cm well-circumscribed tan and focally hemorrhagic mass confined to the adrenal gland. Histologically, the mass was composed of pleomorphic round to polygonal cells with clear to eosinophilic cytoplasm and spindle cells. The mitotic count exceeded 20 in 50 high power fields. Lymphovascular invasion and extensive necrosis were present. Immunohistochemical studies revealed that the sarcomatoid component expressed SF1 and synaptophysin focally. The non-sarcomatoid component exhibited focal expression of synaptophysin and diffuse expression of SF1 and Melan A. Both components displayed null expression of p53, and neither expressed β-catenin. Ki67 proliferation index was > 95% in the sarcomatoid component.
Results (if a Case Study enter NA)
NA
Conclusion
In sarcomatoid ACC, both sarcomatoid and non-sarcomatoid components have been shown to harbor TP53 and CTNNB1 mutations, with the latter leading to activation of Wnt pathway and causing diffuse and strong nuclear expression of β-catenin. In the present case, tumor cells lacked expression of p53, which might have played a role in the evolution of the tumor.

Abstract
Abstract
Introduction/Objective
Although not endemic in the United States, Schistosoma infection can be encountered in clinical samples from patients that have been in endemic regions and can present a challenge to the pathologist. Usually, intestinal schistosomiasis present with a granulomatous inflammatory reaction surrounding the eggs. Schistosome eggs can be found throughout the lamina propria, mucosa, and or submucosa of the intestinal wall.
Methods/Case Report
We present a 79-year-old Asian male, with history of chronic constipation. He was previously diagnosed with schistosomiasis 11 years ago. He received antischistosomal treatment, however, no further tests were done to confirm parasite eradication. Initial endoscopic examination of the colorectum demonstrated two polyps: the first was 2 cm in diameter, located 10 cm proximal from the anal verge, while the second was 2cm in diameter, located 20cm proximal to the anal verge. A biopsy of the first polyp showed a tubular adenoma while the second polyp was hyperplastic showing few calcified schistosome eggs in the submuscosa. Eight days later, a second endoscopy was performed to resect the entirety of the first polyp. Microscopy examination showed sessile tubular adenoma with high grade dysplasia. In addition, there was abundant calcified 50-75 micrometer ova of Schistosoma sp., occupying the submucosa beneath the adenoma without associated inflammation.
Results (if a Case Study enter NA)
NA.
Conclusion
To our knowledge, there are a few case reports describing colonic Schistosoma eggs without inflammation in the presence of tubular adenoma. Our case report adds to the sparse literature that can aid in identifying associations in the future.

Abstract
Abstract
Introduction/Objective
Uterine leiomyosarcoma is a malignant neoplasm with three distinct histologic subtypes: spindle, epithelioid, and myxoid. Distinguishing leiomyosarcoma from mesenchymal uterine neoplasms such as endometrial stromal sarcoma can be challenging as they may exhibit a similar histology and immunohistochemical profile. In such cases, molecular studies can help achieve the definitive diagnosis. It has been shown that ~25% of the uterine myxoid leiomyosarcomas harbor TRPS1-PLAG1 and RAD51B-PLAG1 gene fusions. To our knowledge, no uterine leiomyosarcoma with RAB2A-PLAG1 gene fusion has been previously reported in the English literature.
Methods/Case Report
An 80-year-old woman presented with abnormal uterine bleeding. A large necrotic uterine mass with no evident lymphadenopathy was detected on imaging. Endometrial curettage demonstrated a malignant mesenchymal neoplasm that was positive for CD10, desmin, and vimentin and lacked expression of SMA, SMMH, synaptophysin, and chromogranin. AE1/AE3 highlighted rare foci. The patient underwent total hysterectomy with bilateral salpingo-oophorectomy. The hysterectomy specimen was notable for a 10.8 cm rubbery focally calcified tan- white mass histologically composed of high-grade spindle and epithelioid cells with hypocellular and hyalinized areas. The mitotic activity was >25/10HPF. Immunohistochemically, the neoplastic cells expressed CD10, caldesmon, desmin (patchy), SMA (weak focal), and CAM5.2 (patchy) while they were negative for ER, PR, HMB45, AE1/AE3, WT1, cyclin D1, BCOR, myogenin, pan-NTRK, and ALK. P53 staining showed a wild type expression pattern.
Histology and immunohistochemistry could not definitively differentiate between leiomyosarcoma and high grade endometrial stromal sarcoma. RNA sequencing identified a RAB2A-PLAG1 gene fusion. In light of the histology and ancillary studies, a diagnosis of leiomyosarcoma was rendered.
Results (if a Case Study enter NA)
NA
Conclusion
This is the first case of a uterine leiomyosarcoma with RAB2A-PLAG1 gene fusion. Pathologists should be cognizant of the extensive morphologic and immunophenotypic overlap between various uterine mesenchymal neoplasms. In challenging cases, molecular analysis is crucial in allowing the pathologist to arrive at the final diagnosis.

Abstract
Abstract
Introduction/Objective
Chromophore renal cell carcinoma (ChRCC) accounts for approximately 4-10% of renal cell carcinomas. Compared with other subtypes of renal cell carcinoma, ChRCC generally has a more favorable outcome; however, sarcomatoid transformation is greatest in ChRCC. We report a case of ChRCC with extensive sarcomatoid transformation, which included the heterologous elements of osteosarcoma and chondrosarcoma. The presence of heterologous elements is distinctively rare, with only twelve previous cases in the English literature.

A 64-year-old man presented with left flank pain and night sweats. The abdominal MRI showed a large exophytic hypervascular mass in the left kidney with metastasis to the left para-aortic lymph nodes. The patient underwent radical nephrectomy. Two months after the surgery, the patient was found to have extensive bony metastases. On gross examination, the nephrectomy specimen showed an 18 cm tumor replacing almost the entire kidney. The cut surface was white to tan with areas of hemorrhage and necrosis. Microscopic examination revealed a predominantly sarcomatoid ChRCC (nearly 80% of the tumor) with heterologous chondrosarcoma and osteosarcoma. The tumor extended into the perinephric adipose tissue and the adrenal gland. Multiple para-aortic lymph nodes contained sarcomatoid tumor with heterologous elements.
Results (if a Case Study enter NA)
NA.
Conclusion
ChRCC is frequently considered a more indolent renal cell carcinoma. It is important to recognize its higher propensity for sarcomatoid transformation. The presence of heterologous elements is exceptionally uncommon. Whether this correlates with a more aggressive tumor is not known because of the paucity of such cases.

Abstract
Abstract
Introduction/Objective
Dermatofibrosarcoma protuberans (DFSP) is a superficial and locally aggressive cutaneous soft tissue sarcoma. In most patients, DFSP arises from the trunk and proximal extremities with breast being an uncommon location. Although they rarely metastasize (<5%), DFSP variants tend to recur locally. Most molecularly characterized cases have been defined by the translocation t(17;22)(q21.3;q13.1), which yields a fusion of the COL1A1 and PDGFB genes. In routine practice, dual fusion or break-apart fluorescence in situ hybridization (FISH) for the COL1A1-PDGFB fusion gene is the most widely used screening method for DFSP. However, in ~4% of typical DFSP cases, routine FISH screening is negative. In some of the DFSP cases negative for COL1A1-PDGFB fusion gene by FISH, RNA sequencing has identified two novel gene fusions, COL6A3-PDGFD and EMILIN2-PDGFD, with the former having a predilection for the female breast.
Methods/Case Report
We present a 32-year-old woman who underwent a biopsy for a 3.4 cm echogenic firm mass in her right breast. Histology showed a cytologically-uniform spindle cell neoplasm with fibroblastic morphology. The neoplastic cells displayed a storiform growth pattern and honeycomb-like infiltration of the adipose tissue. Immunohistochemically, the neoplastic cells expressed CD34 and vimentin and were negative for AE1/AE3, p63, S100, CD31, SMA, β-catenin, and STAT6. PDGFB break-apart FISH was negative. Based on the histologic and immunohistochemical findings, a diagnosis of DFSP was rendered. FISH for PDFGD rearrangements or RNA sequencing targeting PDGFD was not performed at this time.
Results (if a Case Study enter NA)
NA.
Conclusion
Awareness is warranted for the rare variant of DSFP with a predilection for female breast, which is characterized by a novel gene fusion not detectable by routine FISH used for DFSP screening.

Abstract
Abstract
Introduction/Objective
Sporadic fumarate hydratase (FH)-deficient leiomyoma occurs as a result of somatic inactivation of the FH gene and has been found to represent 1% of uterine leiomyomas. Germline inactivation of the FH gene is associated with a rare autosomal dominant syndrome known as hereditary leiomyomatosis and renal cell carcinoma (HLRCC). Women with HLRCC develop cutaneous and uterine leiomyomas and an aggressive renal cell carcinoma, with 57% reported to undergo hysterectomy at 30 years of age or younger. All FH-deficient leiomyomas display a distinct histology characterized by scattered bizarre nuclei, eosinophilic cytoplasmic inclusions, conspicuous eosinophilic nucleoli, and perinuclear clearing. Immunohistochemically, the neoplastic cells do not express FH while they are positive for S-(2-succino)-cysteine (2SC), a metabolite that accumulates when FH is inactivated.
Methods/Case Report
We present a 48-year-old woman who underwent supracervical hysterectomy for a symptomatic uterine leiomyoma. She was status post left salpingo-oophorectomy for left adnexal endometriosis. Grossly, the hysterectomy specimen was significant for one 8.0 cm intramural uterine corpus tumor with a tan-white whorled cut surface. Histology showed a smooth muscle neoplasm in the myometrium composed of spindled cells with abundant eosinophilic cytoplasm, occasional enlarged prominent nucleoli with perinuclear halos, intracytoplasmic eosinophilic globules, focal bizarre nuclear atypia and thin-walled staghorn vessels with widespread hyaline necrosis with no mitotic activity. Immunohistochemical studies demonstrated that the neoplastic cells expressed desmin, SMA, SMMH, and 2SC and were negative for FH; consistent with a FH-deficient leiomyoma.
Results (if a Case Study enter NA)
NA
Conclusion
Although rarely seen, pathologists should be cognizant of FH-deficient neoplasms. Genetic counseling and close follow up of the individuals harboring germline inactivating mutations of the FH gene could lead to early detection of the RCC in these patients and their family members.

Abstract
BACKGROUND Infectious bronchitis virus (IBV) causes severe economic losses worldwide. IBV has a broad tissue distribution with different viral loads in different tissues. Additionally, IBV can induce apoptosis in infected cells. AIMS The present study aimed to evaluate the role of the genetic background of chickens in viral load and the expression level of apoptotic genes in different tissues of two hybrids of commercial broiler chickens (Ross 308 and Cobb 500) challenged with IBV. METHODS Chickens at 21 days of age were nasally challenged with 200 μL of allantoic fluid containing 104 EID50/ml of Iranian variant-2-like IBV (IS/1494). The expression level of apoptotic genes (Fas, FasL, Bax, and Bcl-2) in the tracheal and renal tissues and the amount of viral load in the tracheal, renal, and cloacal swab samples were investigated two, five, and seven days after IBV infection by RT-qPCR assay. RESULTS The amount of viral load and apoptotic the expression level of apoptotic genes in the tracheal (two and five days after infection) and renal samples (seven days after infection) were significantly higher in the Ross challenged group than in the Cobb challenged group.Furthermore, no difference was observed in the cloaca viral load on sampling days. CONCLUSION To our knowledge, this is the first report that evaluated the role of the chickens' genetic background in the amount of viral load and the expression level of apoptotic genes against IBV. Further studies are needed to investigate the pathogenic characteristics of IBV in Ross 308 and Cobb 500 chickens.

Abstract
Background Fowl adenoviruses (FAdVs) are responsible for a variety of clinical symptoms, with an increasing significance in the poultry industry throughout the world. Typical diseases caused by FAdVs include inclusion body hepatitis (IBH), hepatitis-hydropericardium syndrome (HHS), gizzard erosion (GE), respiratory disease, and hemorrhage in muscles and organs. Aims During 2020, broiler chickens from the north of Iran showed ecchymotic and petechial hemorrhages in thigh and breast muscles at the slaughterhouse. Hemorrhages were observed in 10% to 60% (with an average of 20-30%) of chicks per flock. To find out the etiology of these lesions, the present study was conducted. Methods Different environmental factors were investigated, and FAdV, infectious bursal disease virus (IBDV), and chicken infectious anemia virus (CIAV) were detected using molecular assays. Results Among the viruses tested, FAdV was detected by polymerase chain reaction (PCR), and sequence analysis clustered the virus into species E, serotype 7. Conclusion This is the first report on FAdV-7 existence among poultry in Iran. Effective screening of the chicks at slaughtering age should be performed from the whole country.

Abstract
Background Avian metapneumovirus (aMPV) infection has significant economic impacts on the poultry industry all around the world. Aims The aim of this study is molecular investigations of different types of aMPV in broiler farms in different provinces of Iran from 2016 to 2018. Methods Tracheal and oropharyngeal swabs were collected from two hundred broiler chickens with respiratory signs in ten provinces of Iran, including Kurdistan, West Azerbaijan, Semnan, Esfahan, Sistan and Baluchistan, Qazvin, Khuzestan, Fars, Gilan, and Khorasan Razavi from February 2016 to December 2018. After RNA extraction, the presence of aMPV was confirmed using N gene special primers. Then, subtype-specific primers were utilized to differentiate the specific subtype. All positive samples were sequenced. Results As a general trend, the percentage of aMPV positive chickens increased gradually over time. All samples were clustered together and placed in the subtype B aMPV group. Although 2 samples from 2016 and 2 samples from 2018 were placed in a separate branch, most of the current study samples of 2016, 2017, and 2018 revealed six segregated sub-branches, and they were placed close to other isolates of 2011 and 2013 from Iran. Conclusion The current field study indicated the presence of aMPV in a considerable number of areas in Iran. Thus, the role of this virus in broiler respiratory complex should not be neglected.

Abstract
1. In recent months, several outbreaks with clinical signs of MDV-1 were reported in Iranian parent and laying hen farms, in addition to backyard chickens. Several meq gene sequences from these outbreaks were amplified and molecularly characterised.2. The meq protein sequences revealed three different sizes, namely the standard 339 aa, a shorter form of 338 aa lacking a proline residue at position 191, and a very short (vs) size of 265 aa. Based on sequence and size, the 265 aa meq has never been reported from international research groups before. The protein has only one PPPP repeat motif suggesting it belongs to a highly virulent strain.3. The standard meq sequences showed 100% BLAST identity to the vv+ isolate Polen5. However, the 338 aa form clustered to the clade usually reported from North America.4. This is the first report on genetic analysis of MDV-1 from Iran, but further study is required to obtain a better picture of the diversity and prevalence of different MDV-1 strains circulating in the country's farms, backyard poultry and other bird species.

Abstract
Newcastle disease is a highly contagious viral infection affecting many species of birds that can spread fast between poultry houses and cause a heavy economic burden on the poultry industry all around the world. Fusion and hemagglutinin-neuraminidase (HN) protein are important in the pathogenesis of the Newcastle disease virus (NDV). The HN protein is a critical viral protein with multiple functions and plays a key role in the formation of the virulence of NDV. Head of HN protein is responsible for receptor binding, neuraminidase activity. This study aimed to investigate the sequence homology of hemagglutinin-neuraminidase of two NDV isolates sampled from infected farms in Iran. The samples were collected from flocks that had been vaccinated by both types of live and killed vaccines for NDV. After isolation of NDV, the viruses were subjected to the polymerase chain reaction (PCR) amplification using two pairs of specific primers designed for the HN gene to amplify the complete HN gene (1730bp). Afterward, the PCR products were sequenced and analyzed by phylogenetic tree construction software. Based on the analysis, substantial sequence homology among Iranian isolates is within the range of 97.1-100%. Moreover, the sequence homology searching revealed a level of similarity between HN sequences of Iranian isolates and the HN sequences from other countries, particularly Asian ones. For instance, a high homology ratio (95.34%) was found between Iranian isolates and the sequences registered on online molecular databases from China. Based on phylogenetic analysis, the NDV isolates belong to the VIId genotype. Finally, it can be concluded that monitoring the circulation of NDVs among poultry and other birds can help to obtain an insight into the evolution of NDVs and control of panzootic viruses in the future.

Abstract
BACKGROUND The chicken infectious anemia virus (CIAV) is an important pathogen that causes severe immunosuppression in young chickens. AIMS The study aims to characterize the genotype and full-length sequencing of CIAV strains in Iran. METHODS First, the collected thymus samples were investigated by conventional PCR for CIAV detection. Second, one of the CIAV positive samples (UT-Zahraee) was chosen for full genome sequencing. RESULTS Throughout 2017, we detected 13 CIAVs isolated from 40 broiler flocks of different provinces of Iran. A comparison of the complete sequences of the genome and homologies of the nucleotides revealed that UT-Zahraee had a high similarity with American and Egyptian CIAV isolates. Moreover, VP1 sequence analysis showed that UT-Zahraee shared high homology with previously reported Iranian CIAV strains, Chinese, and Egyptian isolates. CONCLUSION This study is the first report of full genome sequencing of CIAV strain from Iran. It will be beneficial to understand better the epidemiology and molecular characteristics of CIAV circulating in Iran.

Abstract
Fowlpox is an economically significant viral disease in poultry, characterized by two forms of clinical signs, including cutaneous and diphtheritic lesions. This infection can have several adverse effects on flock performance, such as a reduction in egg production and growth and an increase in mortality. In winter 2018, an infection suspected to fowlpox was reported from a Hy-line W-36 laying farm in Isfahan province, Iran. The birds were 38 weeks of age and showed obvious diphtheritic signs in mucous membranes with increased mortality and reduced egg production. In total, 20 samples were collected from diphtheritic lesions (Trachea and Esophagus) of infected birds. The Polymerase Chain Reaction method was used to amplify a 578 bp fragment of the poxvirus 4b core protein gene. Phylogenetic relationships of avian poxviruses are usually analyzed using the 4b core protein-coding gene sequences with molecular weights of 75.2 kDa. The major elements had the fowlpox genome, and sequencing was performed for one isolate as representative. The nucleotide sequence result showed that this isolate (FP\UT-POX-2018) had a similarity rate of 99.53% with the previous Iranian fowlpox isolate (FP\GHPCRLAB.3) sequenced in the GenBank.Moreover, there was a 100% similarity among the current isolate nucleotide sequence, FP/NobilisVarioleW, and FP/FPV-VR250. The derived phylogenetic tree showed that these isolates were clustered in A1 subclades. Therefore, Iranian isolates of fowlpox virus have remained in the same subclade of phylogenetic classification (subclade A1), and they show high genomic similarity with previous isolates of Iran. Veterinarians and farmers must not underestimate fowlpox. However, they should consider the importance of vaccination against this disease like any other disease care.

Abstract
BACKGROUND/OBJECTIVE Stroke symptoms in the absence of diagnosed stroke are common worldwide and associated with stroke risk factors and great impact on the physical and mental health functioning. The aim of this study was to assess, at the national level, the association of stroke symptoms with mental and physical health. METHODS Quality of life was assessed using physical and mental component summary scores (PCS and MCS) of the Short Form 12v2 Health Survey in the Lebanese population. We assessed the differences in the mean PCS and MCS scores among asymptomatic individuals with no stroke/transient ischemic attack (TIA) history (n=1167), symptomatic individuals with no stroke/TIA history (n=125) and those with stroke/TIA history (n=46). Psychometric properties of the Lebanese version of the SF- 12v2 were evaluated using principal component analysis. RESULTS Symptomatic individuals had an average PCS scores of 2.31 (95%CI: 0.75-3.88) points lower and those with stroke/TIA history had 3.26 (95%CI: 1.01-5.51) points lower when compared with asymptomatic individuals with no stroke/TIA history. Similarly, MCS scores for symptomatic individuals were 2.58 (95%CI: 1.02-4.13) points lower and those with stroke/TIA history had 3.28 (95%CI: 1.06-5.50) points lower than asymptomatic individuals. CONCLUSION Physical and mental health functioning declined among symptomatic individuals and those with stroke/TIA history. Thus, frequent monitoring for the early detection of stroke symptoms may be recommended.

Abstract
Abstract
Biomolecules in solutions subjected to extensional strain can form aggregates, which may be important for our understanding of pathologies involving insoluble protein structures where mechanical forces are thought to be causative (e.g., tau fibers in chronic traumatic encephalopathy (CTE)). To examine the behavior of biomolecules in solution under mechanical strains requires applying rheological methods, often to very small sample volumes. There were two primary objectives in this investigation: (1) To probe flow-induced aggregation of proteins in microliter-sized samples and (2) To test the hypothesis that tau protein aggregates under extensional flow. Tau protein (isoform:3R 0 N; 36.7 kDa) was divided into 10 μl droplets and subjected to extensional strain in a modified tensiometer. Sixteen independent tests were performed where one test on a single droplet comprised three extensional events. To assess the rheological performance of the fluid/tau mixture, the diameter of the filament that formed during extension was tracked as function of time and analyzed for signs of aggregation (i.e., increased relaxation time). The results were compared to two molecules of similar and greater size (Polyethylene Oxide: PEO35, 35 kDa and PEO100, 100 kDa). Analysis showed that the tau protein solution and PEO35 are likely to have formed aggregates, albeit at relatively high extensional strain rates (∼10 kHz). The investigation demonstrates an extensional rheological method capable of determining the properties of protein solutions in μl volumes and that tau protein can aggregate when exposed to a single extensional strain with potentially significant biological implications.

Abstract
BACKGROUND Avian influenza (AI) caused by AI virus subtype H9N2 is a prevalent viral disease with enormous economic losses in poultry farms through significant respiratory and gastrointestinal manifestations. The degree of protection obtained from a vaccine strongly depends on the level of antigenic similarity between challenge and vaccine virus. AIMS The study aimed at investigating the possible effects of continuous antigenic changes occurring in circulating Iranian viruses since 1998 on the commercial vaccines outcome by using vaccine seeds from earlier outbreaks for inhibiting viral replication in target organs of broilers challenged with the recent isolate. METHODS Ninety broilers at one day of age were randomly allocated into 5 groups and vaccinated with autogenous or commercial vaccines (A or B). Two remaining groups consisted of challenged without vaccination and intact birds. Quantitative real time-polymerase chain reaction (qRT-PCR) was performed on the trachea and faecal samples of challenged chickens with recent H9N2 virus to determine viral load. Moreover, humoral antibodies titers were evaluated by hemagglutination inhibition (HI) assay. RESULTS There was no significant difference in H9N2 viral load in the trachea among vaccinated groups on 5 days post challenge (DPC), but on 15 DPC, the autogenous vaccine significantly lowered viral load compared to commercial vaccines (P≤0.05). No significant differences in faecal swab's viral load was observed between autogenous and commercial vaccine A, and both of them significantly inhibited viral load compared to unvaccinated group (P≤0.05). In addition, the autogenous vaccine elicited the highest HI titer. CONCLUSION Inactivated vaccines that use isolates from previous outbreaks are no longer able to induce proper immunity against recent H9N2 viruses. It seems the time to change vaccine strains to more recent isolates that have better antigenic similarity with current circulating H9N2 viruses in the region has come.

Abstract
Soil-associated invertebrates which are coprophagic are capable of acting as paratenic hosts for Toxocara species larvae eggs. The aim of the present study was to assess the role of Lumbricus terrestris earthworms as potential intermediate host for Toxocara species. A total of 240 earthworms were collected from the public places in four areas of Karaj, Alborz Province, Iran. The subjects of the study were digested to detect Toxocara species using microscopy and molecular analyses. Toxocara larvae and larval eggs were recovered from 1.7% (4/240) of the sampled earthworms. The recovery rate in Shah'Abbasi and Talaghani regions in the studied areas was higher than that of the other regions. In the mentioned area, 8.3% (4/48) of earthworms were revealed to be positive for Toxocara species by microscopic observation and only one was confirmed to be positive for Toxocara canis by polymerase chain reaction (PCR). This is the first molecular report of Toxocara canis infective larvae in Lumbricus terrestris earthworms that could be demonstrated in common environment.

Abstract
BACKGROUND Avian infectious bronchitis (IB) is an infectious viral disease of chickens. The effective protection of chickens against many different infectious bronchitis virus (IBV) variants is not achieved unless the circulating genotypes in the region are identified and the cross-protection of the potential of vaccines in use is assessed. AIMS In a monitoring program of IBVs, a new genotype was identified in the north of Iran, 2019. This work was conducted to isolate and characterize this new IBV genotype. METHODS Tracheal tissues were collected from chickens showing signs of respiratory involvement. Specimens were homogenized and inoculated to the allantoic fluid of embryonated specific pathogen-free (SPF) eggs. Infectious bronchitis virus was detected using real time-polymerase chain reaction (RT-PCR). The hypervariable region of the IBV S1 gene was amplified for sequencing. RESULTS Positive samples were phylogenetically analyzed, and both positive isolates were clustered with Q1 IBV strains. CONCLUSION This is the first report of the Q1 outbreak in Iran. More investigations are needed to find the role of Q1 IBV in the respiratory disease complex of chickens.

Abstract
Avian influenza (AI) is an acute infectious disease with worldwide significance causing extensive economic losses in the poultry industry. Avian influenza viruses (AIVs) belong to the family Orthomyxoviridae and categorized in the genus influenza virus A. These viruses have been isolated from more than 100 species of free-living birds. Migratory birds are considered as reservoirs for AIVs and are the major agents responsible for global outbreaks. The Passeriformes are found in most parts of the world and cover a variety of habitats from rural to urban areas. House sparrows are members of the family Passeridae and due to their free flying, are strongly associated with seabirds, indigenous, and industrial poultry. The aim of this study was to determine the role of house sparrows in AIV (H9N2) circulation in the Ahvaz region. The intestinal and tracheal samples were taken from 200 sparrows around Ahvaz during 2017. Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed using specific primers in order to detect M and H9 genes of AIVs. The positive specimens in the PCR for the M gene were inoculated into 9-11-day-old embryonated chicken eggs via the allantoic fluid. The results showed that 11 out of 200 samples were positive for the two genes of M and H9. According to the findings of the present study, house sparrows are infected with H9N2 and pose a threat to commercial poultry. These birds may play a significant role in the transmission of AIV between wildlife and domestic animals. Therefore, this issue is important to be considered in preventive measurements.

Abstract
Gamma Coronaviruses (GCoVs) are distributed worldwide, affecting a wide range of bird species, the beluga whale, and bottlenose dolphins. Because of the limited proofreading capability in the viral encoded polymerase, they emerge genetically diverse. There has been no molecular surveillance data to describe the epidemiology of GCOVs in avian species. The present study was conducted to detect GCOVs in Tehran birds&rsquo; parks, 2015. Cloacal swabs (267 samples) from eight different bird species ((Chickens (Gallus gallus), Pheasant (Phasianus colchicus), Turkey (Meleagris gallopavo), Partridge (Perdix perdix), Quail (Coturnix coturnix), Duck (Anas platyrhynchos), Goose (Anserini),and Guinea fowl (Numididae)) were collected, the viral RNA was extracted, the RT-PCR was performed using QIAGEN one step RT-PCR kit and the primers targeting &ldquo;3&#39;-UTR&rdquo; and &ldquo;Nucleocapsid&rdquo; genes. The detection rate was approximately 8.99%. GCOVs were detected in the chicken, quail, pheasant, turkey, and the partridge with different prevalence rates. Phylogenetic tree based on partial nucleotide sequences of the N gene clustered the samples into two groups. It is the first report of GCOVs in non-commercial birds in Iran. According to our results, GCOVs are circulating in different avian species, and further studies are needed to isolate these viruses and evaluate their pathogenesis.

A new library of spiropyrans were synthesized via a one-pot four component reaction of cyanoacetohydrazide, ninhydrin, malononitrile and various cyclic CH-acids in EtOH at reflux conditions. The products were isolated and tested in vitro for antibacterial effects on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Furthermore cytotoxic activity of the spiropyrans on non-small-cell lung cancer cells (A549 cells), a breast epithelial cancer cell line (MCF-7), human malignant melanoma cells (A375), prostate cancer cells (PC3 cells, LNCaP cells) and normal cells HDF (human dermal fibroblast) was investigated. Interestingly, it was found that compounds 5a, 5b, 5f, 5g and 5i have the best MIC against S. auerus and compound 5a displayed the most potent activity against A549, A375, and LNCaP tumor cells. Moreover, DAPI staining of the A549 cancer cell lines that were treated with 5a were associated with the death of A549 cells. By using RT-PCR method, it was finally confirmed that apoptosis occurs in A549 cells by up-regulated Bax expression and down-regulated Bcl-2 expression from the mitochondrial pathway of apoptosis.

Abstract
Here, we have described the synthesis of novel spiropyridineoxindole derivatives containing a pyridone ring via a four-component reaction between various diamines, 1,1-bis(methylthio)-2-nitroethylene, isatin derivatives and Meldrum's acid in the presence of p-toluenesulfonic acid. This protocol has some advantages such as the availability of starting materials, good yields, facile separation of products, the use of ethanol as an environmentally benign solvent and easy formation of three new bonds in one operation.

Abstract
Aflatoxin M1 is an oxidative metabolite of aflatoxin B1 formed in liver and excreted into milk, urine and faeces of dairy cattle and other mammalian species. The International Agency for Research on Cancer classified aflatoxin M1 in Group 2B because of its potential to get bioactivated to a mutagen analogous to aflatoxin B1. Risk assessments are undertaken to guide food regulators and scientists in risk management processes, such as the legislative levels or guideline targets for mycotoxins in food supplies. Using existing international resources for hazard data and local exposure data, and based on cancer potency as the endpoint, the risk of exposure to aflatoxin M1 in milk for the Iranian population was calculated considering various scenarios. During 2014-2015, 518 samples were collected from the market and tested for aflatoxin M1 contamination by HPLC-FLD. The most probable scenarios calculated as mean occurrence multiplied by the mean consumption in consumers of milk, and for maximum level allowed for aflatoxin M1 in milk with 99 percentiles of milk consumption showed the risk of 0.08 and 0.72 additional liver cancer cases per year for the Iranian population, respectively. Thus, our study reveals a low risk and that the current maximum limit of 100 ng/l for aflatoxin M1 in milk, heat treated milk and flavoured milk is sustainable.

Abstract
Listeria monocytogenes, as a foodborne pathogenic bacterium, is considered as major causative agent responsible for serious diseases in both humans and animals. Milk and dairy products are among the main sources of energy supply in the human, therefore contamination of these products with Listeria spp., especially L. monocytogenes, could lead to life threatening infections in a large population of people. Rapid and accurate detection of L. monocytogenes in milk and dairy products, vegetables, meat, poultry, and seafood products is needed to prevent its dissemination through the food chain. Upon contamination of food materials with this pathogen, increase in its antibiotic resistance rate can occur after exposure to preservatives, antibiotics, and stress conditions, which has now become another major public health concern emphasizing the need for special attention on its control along the food chain and management of the disease in the patients. This review provides an overview of researches with respect to the prevalence of Listeria spp., especially L. monocytogenes, in milk and dairy products, methods of their detection and typing, and current status of resistance rates to the antibiotics used for treatment of listeriosis.

Abstract
BACKGROUND Avian infectious bronchitis (IB) is a highly contagious viral disease which affects the poultry industry. The virus exists in a wide variety of genotypes, and phylogenetic analysis has been used to classify infectious bronchitis virus (IBV) strains. AIMS The object of the study is a molecular characterization of circulating IBV in Afghanistan as a first study. METHODS The tracheal tissue specimens from 100 different commercial broiler flocks with respiratory distress in Afghanistan were collected during 2016-2017. After real-time reverse transcriptase-polymerase chain reaction (RRT-PCR), IBV-positive samples were further characterized. A 390 bp hypervariable spike glycoprotein gene segment was amplified using Nested PCR, sequenced, and analyzed. RESULTS The results of real-time RT-PCR showed that 45/100 of the mentioned flocks were IBV positive. Phylogenetic analysis of all positive samples revealed that IBV strains were clustered into two distinct genotypes: LX4 (GI-19) (9/45) and IS-1494 like (GI-23) (34/45). Also, 2 of the 45 samples remained uncharacterized. CONCLUSION It is the first study focusing on the molecular epidemiology of IBV in Afghanistan, extending our understanding of IB in the region. These results showed the high rate of IB infection in Afghanistan broiler farms and confirm the continuing monitoring of IBVs to modify the vaccination program.

Abstract
A simple and convenient protocol has been developed for the synthesis of N-amino-3-cyano-2-pyridone derivatives by a one-pot reaction of cyanoacetohydrazide, activated nitrile substrates (malononitrile, ethyl cyanoacetate, cyanoacetamide) and aromatic aldehydes in the presence of piperidine in water or a mixture of water and ethanol. The sequence of cascade reactions includes Knoevenagel condensation, Michael addition, intramolecular cyclization, imine-enamine tautomerization and oxidative aromatization. The main advantages of this procedure are availability of starting compounds, simple procedure, mild conditions, easy purification of products and the use of water or water/ethanol as green solvents.

Abstract
BACKGROUND Cryotherapy using Wartner compound that contains a mixture of dimethyl ether (75%) and propane (25%) has been recently reported as an effective treatment for warts. The present study aimed to evaluate the safety and efficacy of Wartner in male patients with genital warts. METHODS A Phase II parallel-randomized clinical trial was performed on 16 Iranian men affected by genital warts who were referred to a dermatology clinic at Tehran University of Medical Sciences. Two genital warts of each patient were selected and randomly assigned to receive either Wartner (intervention) or liquid nitrogen (control). RESULTS Two weeks after the treatment, the sizes of the lesions in control and intervention groups decreased by 17.87 ± 2.14 mm2 and 15.81 ± 1.80 mm2, respectively (p = .299). Fourteen days after a single session of treatment, 81% of lesions in the control group and 50% in the Wartner group were completely eradicated, however, the difference was not statistically significant (p = .063). CONCLUSIONS The Wartner compound is as effective as the conventional cryotherapy method for treating genital warts. It is particularly valuable when there are contraindications or no access to common treatment options.

Abstract
M. synoviae (MS) is an economically important pathogen and the major cause of airsacculitis and infectious synovitis in turkeys. Infection with this pathogen may remain asymptomatic but can render infected birds susceptible to secondary infections. This study was carried out for the molecular detection of MS infection in commercial and backyard turkey flocks in Tehran, Semnan, Isfahan, Qazvin, Zanjan, East Azerbaijan, Gilan, Mazandaran, and Golestan provinces of Iran. Sixty-hundred tracheal, choanal cleft or/and infraorbital sinus samples were collected from 18 commercial and 31 backyard turkey flocks. The polymerase chain reaction (PCR) technique was performed by using primers specific for detecting the 16S rRNA and vlhA genes of MS. The results showed that 51.61% of backyard and 33.33% of commercial farms were MS-positive. These findings suggested the molecular presence of MS, especially in northern and central regions of Iran. Further, the frequency of MS-positive samples was significantly lower in commercial farms than backyard farms (P&lt;0.05).

Abstract
A needle-free vaccine/drug injector that works by virtue of the impulse of a moving shock wave is presented in this communication. The device can deliver controlled micro-volumes of liquid vaccines into skin and soft tissue targets in human with minimal invasion. The operation of the injector was investigated by delivering a dyed liquid into human skin samples and soft tissue models. The depth of penetration of the liquid was examined by histology of the targeted human skin samples. The delivery mechanics and the depth of penetration were analyzed theoretically with an elastic model for the skin and a viscoelastic model for the soft tissue targets, and a good agreement with experiments was observed. The current liquid vaccine/drug delivery technique can reduce pain, trauma and contamination, and can offer a cost-effective, needle-free, health-care solution.

Abstract
Infectious bursal disease (IBD) virus causes a highly contagious immunosuppressive disease in chickens. A total number of 12 pooled bursal samples were collected during 2014-2015 from broiler farms in different regions of Iran. Typical macroscopical and histopathological lesions of the bursa of Fabricius were found similar to reports by other researchers. A 474-bp part of hypervariable region of VP2 (hvVP2) was sequenced and analyzed. Ten isolates had the characteristic amino acid residues of very virulent IBD (vvIBD) viruses and the other two were identified as attenuated (vaccine) strains. The vvIBD isolates had a unique G to S mutation at position 254, compared to other Iranian vvIBD isolates. Two attenuated isolates had the mutation 253Q, not found in D78 strain, creating virulent variant of vaccine strains. Degree of similarity among the studied vvIBD isolates was relatively high (97.6-100%), proposing a common ancestor for them. However, they were partly different from previous Iranian and neighbor countries' isolates (96.2-97.3% similarity to Shiraz isolate and 95.7-96.7% to Iraq and Turkey isolates). In phylogenetic analysis, the studied vvIBD isolates classified as a separate subgroup in the group of isolates from Iran and neighbor countries. More studies on genetic and antigenic characteristics of these isolates as well as probable modifications in their pathogenicity are needed to evaluate the significance of the mentioned differences.
