Abstract
OBJECTIVES The purpose of this study is to analyze the relationship between the occurrence of the National Brain Injury Awareness Week and public interest in the concussion topic in Australia through an analysis of Internet search activity data from Google Trends. STUDY DESIGN Online retrospective observational study. METHODS For the keyword "concussion", the search interest rate over a period of 10 years between August 2012 and August 2022 within Australia has been analyzed using the Google Trends tool. The rising related topics that contributed to the months with the highest search interest were extracted for each year and a trendline analysis was performed to capture temporal patterns. RESULTS There was a significant difference in the average search interest between the month of August, when the Brain Injury Awareness Week is annually held, and the rest of the year (d = 0.09, p = 0.017). Also, May and August were the two months with the overall highest search interests (mean ± SD: 73.3 ± 5.16 and mean ± SD: 70.1 ± 5.49, respectively). Trendline analysis showed a positive slope of 0.3081 with R2 = 0.4462 for search interests of concussion over the 10-year period. CONCLUSIONS The data suggest that there is a growing interest and potential awareness of concussion in Australia that seems highly limited to the context of sports such as football, rugby, and soccer. Major sports events, news coverage, and media exposure appear to be associated with this trend. The study highlights the importance of more investment in producing engaging media content to educate the public on concussion of different causes and improving strategies for National Brain Injury Awareness Week.

Abstract
Thromboembolic diseases are a major cause of mortality in human and the currently available anticoagulants are associated with various drawbacks, therefore the search for anticoagulants that have better safety profile is highly desirable. Compounds that are part of the dietary routine can be modified to possibly increase their anticoagulant potential. We show mannose 2,3,4,5,6-O-pentasulfate (MPS) as a synthetically modified form of mannose that has appreciable anticoagulation properties. An in silico study identified that mannose in sulfated form can bind effectively to the heparin-binding site of antithrombin (ATIII) and heparin cofactor II (HCII). Mannose was sulfated using a simple sulfation strategy-involving triethylamine-sulfur trioxide adduct. HCII and ATIII were purified from human plasma and the binding analysis using fluorometer and isothermal calorimetry showed that MPS binds at a unique site. A thrombin inhibition analysis using the chromogenic substrate showed that MPS partially enhances the activity of HCII. Further an assessment of in vitro blood coagulation assays using human plasma showed that the activated partial thromboplastin time (APTT) and prothrombin time (PT) were prolonged in the presence of MPS. A molecular dynamics simulation analysis of the HCII-MPS complex showed fluctuations in a N-terminal loop and the cofactor binding site of HCII. The results indicate that MPS is a promising lead due to its effect on the in vitro coagulation rate.Communicated by Ramaswamy H. Sarma.

Abstract
The cross-section area is a crucial parameter to assess peripheral neuropathy. The ultrasonographic evaluation of cross-section area of median nerve is a low-cost and readily available tool for diagnosis and assessment. However, the intra-nerve dimensional variability and its normative reference value in a healthy subject are missing. The current meta-analysis aims to capture the median nerve cross-section area for healthy subjects and generate a comprehensive ultrasonographic reference data set for each population. METHODS The full text of manuscripts were collected after short-listing the abstracts collected from search strategy. A quality assurance tool was used to capture the risk of bias of each study after reviewing the included manuscripts. The pooled estimate of cross-section area was stratified according to anatomical landmarks, sex, and ancestry. RESULTS A total of 97 observational studies dealt with 6679 wrists of healthy subjects were included. The pooled estimate of the cross-section area of median nerve at carpal tunnel inlet was 8.54mm2 [95% CI: 8.34-8.74mm2]. The same pooled estimate at carpal tunnel outlet was 8.03mm2 [95% CI: 7.46-8.60mm2]. Both these pooled estimates have significant correlation with mean age of population. Age and sex were two primary predictors of the cross-section of median nerve. The flattening ratio, circularity, and wrist-forearm ratio of median nerve were also computed. CONCLUSION These normative data could serve as a reference for assessing median nerve pathologies, including carpal tunnel syndrome. The ethnic variation of pooled estimate and heterogeneity will guide clinician set up the reference value for diagnostic criteria.

Abstract
Abstract
Introduction/Objective
Nodular fasciitis is a rapidly growing but benign self-limited myofibroblastic/fibroblastic tumor of unknown etiology. It was first described in the literature by Konwaler in 1955 and can occur in any location. Nodular fasciitis of the tongue is a rare entity in infancy with only one case reported so far. Accurate diagnosis of this entity is crucial to avoid a possible misdiagnosis of malignancy leading to radical resections.
Methods/Case Report
A 6-month old, previously heathy full term male presented to pediatric otolaryngology clinic with a rapidly growing painless mass on the right tongue. The mass was associated with feeding difficulty. There was no history of trauma to the area, no personal and family history of cancer was noted. Computed tomography scan demonstrated a 1.5 x 1.4 x 1.5 cm mass confined to the right anterior undersurface of tongue. Biopsy of the mass showed ulcerated mucosa with an underlying spindle cell lesion composed of reactive-appearing myofibroblasts arranged in a variably fascicular to "tissue-culture" pattern, intermixed with inflammatory cells and scattered extravasated erythrocytes. These morphologic features in conjunction with immunohistochemistry and demonstration of fusion of SRSF3 [serine and arginine rich splicing factor 3] and USP6 [ubiquitin specific peptidase 6] by Targeted next-generation RNA sequencing confirmed the diagnosis of nodular fasciitis. On follow up, spontaneous regression of the mass occurred in 3 months.
Results (if a Case Study enter NA)
NA.
Conclusion
Nodular fasciitis of tongue in infancy is an exceedingly rare entity and this case demonstrates the importance of including this unique entity in the differential diagnosis of a rapidly-growing tongue lesion. Because it can simulate malignancy both clinically and histologically, awareness and familiarity with this benign proliferative lesion is crucial in effective management.

Abstract
BackgroundInterstitial lung diseases (ILD) are a diverse group of pulmonary diseases for which accurate diagnosis is critical for optimal management and outcomes. Diagnosing ILD, both idiopathic pulmonary fibrosis (IPF) and connective-tissue-disease-associated interstitial lung disease (CTD-ILD), has become critically important, as the disease has a devastating prognosis with poor survival.There are also management implications, as patients with ILD can now potentially be treated with new antifibrotic therapies such as pirfenidone and nintedanib, both of which have been approved. Certain types of CTD – ILD may benefit from systemic immunomodulatory therapies. Diagnosis of ILD can be challenging and a multidisciplinary team (MDT) approach is recommended in current guidelines. Several studies have reported that MDT diagnosis is associated with higher levels of diagnostic confidence and better interobserver agreement (1-3).ObjectivesWe describe the benefits of an ILD multidisciplinary service on the diagnosis and management of patients with suspected ILD.MethodsWe performed a single-centre retrospective review of consecutive patients referred to the ILD clinic with subsequent discussions in ILD MDTs over a 36-month period from 2016 to 2019. We compared changes in ILD diagnosis and management at referral to those following the ILD-MDT. We collected data on the demographics, occupation, age at ILD onset, smoking status, imaging, blood tests including autoimmune serology, MDT recommendations, change in diagnosis after MDT, tertiary referral, serial PFTs, medications and outcomes. Cases of suspected ILD that were not fully characterised and those with complex management issues were presented at our monthly ILD MDT.ResultsA total of 208 patients were referred to the ILD clinic over a 36-month period. Of these, 106 cases were discussed at the ILD MDT and the remaining 102 cases did not require discussion at the MDT as these deemed to be clear cut, which included RA and CTD ILD. The mean age of the total cohort was 74 (min age 32, max age 97) and 120 (58 %) were males. Overall, evaluation by the ILD service (i.e. ILD clinic and MDT) resulted in a change in diagnosis in 106(51%) patients. Of those, 49(46%) didn’t have ILD. In the remaining 57 patients with suspected ILD, the majority of the diagnoses were ILD with an uncertain classification (24, 23%). The other diagnoses included CTD-ILD (4, 3.7%), ILD with autoimmune serology 11(10.4%), IPF 10(9.4%), Drug-induced-ILD 3(2.8%), Hypersensitivity Pneumonitis 5(4.7%), Eosinophilic pneumonitis 1 (0.94%), Cryptogenic Pneumonitis 1(0.94%), PPFE with IPF 1 (0.94%), PPFE 1 (0.94%), CPFE 4 (0.94%), EAA 2 (0.94%), RB-ILD 2 (1.88%), Langerhans Histiocytosis 2 (1.88%).16/57(28%) were referred to a tertiary centre for further management. Serology was positive in 11 patients (ANA 6, CCP 3, and ANCA 2). Of the 57 patients with other diagnoses, the main recommendations included steroids (28), anti-fibrotic therapy (4), immunomodulatory therapy (6) and ambulatory Oxygen (1). Further analysis will be carried out on survival and treatment outcomes of the cohort.ConclusionDedicated ILD-MDT service has an important clinical impact on the care of the ILD patient, with frequent changes in ILD diagnosis and subsequent management and outcomes. Multidisciplinary approach to the management of these patients should be standard of care for these patients.References[1]Flaherty KR, King TE Jr, Raghu G, et al.

Background
There has been a proliferation of machine learning (ML) electrocardiogram (ECG) classification algorithms reaching >85% accuracy for various cardiac pathologies. Despite the high accuracy at individual institutions, challenges remain with cross-institutional algorithm evaluation. Transfer learning (TL) is a technique in which a model trained for a specific task is repurposed for another related task, in this case ECG ML model trained at one institution used to classify ECGs at another institution. Models trained at one institution, however, might not be generalizable for accurate classification when deployed broadly due to differences in type, time, and sampling rate of traditional ECG acquisition. TL would thus require additional ECG signal processing which inherently introduces noise and has high computational costs. Our previous work has shown that frequency domain (FD) convolutional neural networks (CNN) outperform traditional time domain (TD) CNN methods in detecting atrial fibrillation (Afib) and are more robust against noise and sampling variations.
Purpose
In this study, we explore ECG transfer learning by comparing performance of TD and FD CNN ECG classification models. Examine the hypothesis that FD signal analysis can overcome limitations inherent to TD and demonstrate application for Afib classification in three different publicly available datasets.
Methods
PTB-XL ECG dataset was used to train TD and FD CNN models for Afib classification. TL on the two data sets, Lobachevsky University Electrocardiography Database (LUDB) and KURIAS-ECG database (KURIAS), was performed with portions of each dataset added to PTB-XL training data before test runs on the remaining ECGs. The models were also tested directly on the two datasets (cross-testing) for comparison.
Results
Results of TL are summarized in Fig. 1. Panels (a) and (b) show TD and FD performance on PTB-XL dataset, with FD outperforming TD. Panels (c) and (d) show TL of PTB-XL trained TD and FD models applied on LUDB Afib data with FD outperforming TD. Panels (e) and (f) show TL of PTB-XL trained models applied to KURIAS Afib ECGs, with FD again outperforming TD. Table 1 summarizes results of TL and direct cross-testing with TL outperforming cross-testing.
Conclusions
FD models were superior to TD models in Afib classification, both in cross-testing and TL. TL technique, in which a pre-trained model is used as starting point for novel dataset training, outperformed direct cross-testing. TL with FD CNN has the capacity to leverage models trained on a particular set of ECGs to classify ECGs with varying signal acquisition properties. FD CNN may be robust to inter-institutional variability and has potential for widespread application with no compromise to ECG classification power. A potential application of these findings is deployment of ECG classification CNN models trained at institutions with large ECG databases to hospitals with smaller datasets.

Abstract
Transport disturbs birds' welfare and health status which lead to oxidative stress and dietary ascorbic acid mitigates the adverse effects of transport stress. The present study was aimed to evaluate the impacts of ascorbic acid administration on oxidative stress indices, cortisol, H/L ratio, tonic immobility reaction and rectal temperature of pigeons exposed to road transport. A total of 80 clinically healthy pigeons were selected and randomly divided to eight equal groups as follow: (1) Ctrl- : fed by basal diet and no subjected to transport stress; (2) Ctrl+: fed by the basal diet and subjected to transport stress; (3, 4) 1DBS10 and 1DBS16: received ascorbic acid from 1 day before transport stress at doses of 10 g/100 L and 16 g/100 L of drinking water, respectively; (5, 6) 3DBS10 and 3DBS16: treated with ascorbic acid from 3 consecutive days before transport stress at doses of 10 g/100 L and 16 g/100 L, respectively and (7, 8) 7DBS10 and 7DBS16: received ascorbic acid from 7 consecutive days before the transport at doses 10 g/100 L and 16 g/100 L, respectively. Birds were transported for 3 h over a distance of about 200 km. The total antioxidant capacity, malondialdehyde and cortisol were measured before transport and at 6, 24 and 72 h post-transportation. The rectal temperature and tunic immobility reactions were recorded. Dietary ascorbic acid led to a decrease in tonic immobility response, hetrophil to lymphocyte ratio, circulating cortisol and total antioxidant capacity, and an increase in circulating malondialdehyde in pigeons exposed to transport stress compare to Ctrl+ group. In conclusion, ascorbic acid administration at dose 16 g/100 L of drinking water from 3 and 7 days before exposure to stress helps attenuate undesirable effects of oxidative stress in pigeons.

Abstract
Osseointegration of dental, craniofacial, and orthopedic implants is critical for their long-term success. Multifunctional surface treatment of implants was found to significantly improve cell adhesion and induce osteogenic differentiation of dental-derived stem cells in vitro. Moreover, local and sustained release of antibiotics via nanolayers from the surface of implants can present unparalleled therapeutic benefits in implant dentistry. Here, we present a layer-by-layer surface treatment of titanium implants capable of incorporating BMP-2-mimicking short peptides and gentamicin to improve their osseointegration and antibacterial features. Additionally, instead of conventional surface treatments, we employed polydopamine coating before layer-by-layer assembly to initiate the formation of the nanolayers on rough titanium surfaces. Cytocompatibility analysis demonstrated that modifying the titanium implant surface with layer-by-layer assembly did not have adverse effects on cellular viability. The implemented nanoscale coating provided sustained release of osteoinductive peptides with an antibacterial drug. The surface-functionalized implants showed successful osteogenic differentiation of periodontal ligament stem cells and antimicrobial activity in vitro and increased osseointegration in a rodent animal model 4 wk postsurgery as compared with untreated implants. Altogether, our in vitro and in vivo studies suggest that this approach can be extended to other dental and orthopedic implants since this surface functionalization showed improved osseointegration and an enhanced success rate.

Abstract
Neuroserpin is a serine protease inhibitor expressed mainly in the brain and at low levels in other tissues like the kidney, testis, heart, and spinal cord. It is involved in the inhibition of tissue plasminogen activator (tPA), plasmin, and to a lesser extent, urokinase-type plasminogen (uPA). Neuroserpin has also been shown to plays noninhibitory roles in the regulation of N-cadherin-mediated cell adhesion. It is involved in neuroprotection from seizure and stroke through tPA-mediated inhibition and also through its other protease targets. Mutations in critical domains of neuroserpin lead to its polymerization and neuronal death. In this study, a novel truncated isoform of human neuroserpin was identified in the brain and liver, which was confirmed by reverse transcriptase-PCR and DNA sequencing using exon-specific primers. Structural characterization of novel isoform using MD simulations studies indicated that it lacks the reactive center loop (RCL) but largely maintains its secondary structure fold. The novel truncated variant was cloned, expressed, and purified. A comparative intrinsic fluorescence and 4,4'-bis-1-anilino naphthalene 8-sulfonate studies revealed a decrease in fluorescence emission intensity and a more exposed hydrophobic surface as compared to the reported isoform. However, the novel isoform has lost its ability for tPA inhibition and complex formation. The absence of RCL indicates a noninhibitory role for the truncated isoform, prompting a detailed search and identification of two smaller isoforms in the human brain. With indications of the noninhibitory role of neuroserpin, identifying novel isoforms that appear to be without the tPA recognition domain is significant.

Abstract
Neuroserpin (NS) is an inhibitory protein of serpin super family, its shutter region variants have high propensity to aggregate leading to pathological disorders like familial encephalopathy with NS inclusion bodies (FENIB). Helix F and β-sheet A of NS participate in the tissue plasminogen activator (tPA) inhibition but the mechanism is not yet completely understood. A microsecond (μs) molecular dynamics simulation of the helix F and strand 3A variants showed predominant fluctuations in the loop connecting the strands of β-sheet A. Therefore to understand the role of helix F and strand 3A of β-sheet A, cysteine was incorporated at the position N182 in stand 3A (N182C) and position W154 (W154C) in the helix F using site-directed mutagenesis. Purified variants were further labeled with Alexa Fluor488 C5 maleimide dye. Temperature dependent study using non-denaturing PAGE showed the formation of large aggregates of helix F variant W154C but not the strand 3A N182C variant. Interestingly tPA inhibition was found to be decreased in the labeled N182C with decreased tPA-complex formation as compared to labeled W154C NS variant. The fluorescence emission intensity of the labeled helix F variant W154C decreased in the presence of an increasing concentration of tPA, whereas an increase in emission intensity was observed in labeled strand 3A variant N182C, indicating more exposure of strand 3A and shielding of helix F. Taken together the data shows that helix F has a predominant role in the aggregation but a minor role in the inhibition mechanism.

Abstract
Successful tissue engineering therapies rely on the appropriate selection of the cell source, biomaterial, and regulatory factors. To be applied in a wide range of clinical applications, the ideal cell source needs to be easily accessible and abundant. Human orofacial tissues and teeth harbor several populations of mesenchymal stem cells (MSCs) with self-renewal and multilineage differentiation capabilities. The ease of access, relative abundance, and minimally invasive isolation procedures needed to harvest most types of the dental-derived MSCs render them a promising cell source for tissue engineering applications. A growing body of evidence has reported the profound immunoregulatory potential of dental-derived MSCs as compared with their bone marrow counterparts. Biomaterials can act as a physical barrier protecting the MSCs from the invasion of the immune system by hindering penetration of proinflammatory cells/cytokines, leading to higher viability of the encapsulated MSCs and improved tissue regeneration. Besides their protective capabilities, biomaterials can actively contribute to the immunoregulatory potential of the MSCs through their physical and chemical properties, including porosity and elasticity. However, despite recent advancement, the therapeutic capability of biomaterials to regulate the MSC-host immune system crosstalk and the mechanism underlying this immunoregulation has been poorly understood. It has been reported that biomaterials can regulate the viability and determine the fate of the encapsulated MSCs through modulation of the NF-kB pathway and the caspase-3 and caspase-8 proapoptotic cascades. Additionally, the physiomechanical properties of the encapsulating biomaterial have been shown to modulate clustering of TNF-α receptors on the encapsulated MSCs while regulating the production of anti-inflammatory factors such as indoleamine 2,3-dioxygenase (IDO) and prostaglandin E2 (PGE2) through activation of the P38 MAPK pathway. In the current review, we sought to provide a thorough overview of the immunomodulatory functions of dental-derived MSCs and the role of biomaterials in their interplay with the host immune system.

Abstract
The β decay of ^{208}Hg into the one-proton hole, one neutron-particle _{81}^{208}Tl_{127} nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N>126, Z<82 quadrant of neutron-rich nuclei. While both negative and positive parity states with spin 0 and 1 are expected within the Q_{β} window, only three negative parity states are populated directly in the β decay. The data provide a unique test of the competition between allowed Gamow-Teller and Fermi, and first-forbidden β decays, essential for the understanding of the nucleosynthesis of heavy nuclei in the rapid neutron capture process. Furthermore, the observation of the parity changing 0^{+}→0^{-}β decay where the daughter state is core excited is unique, and can provide information on mesonic corrections of effective operators.

Abstract
Iron plays important roles in healthy brain but altered homeostasis and concentration have been correlated to aging and neurodegenerative diseases. Iron enters the central nervous system by crossing the brain barrier systems: the Blood- Brain Barrier separating blood and brain and the Blood-Cerebrospinal Fluid Barrier (BCSFB) between blood and CSF, which is in contact with the brain by far less selective barriers. Herein, we develop a two-compartmental model for the BCSFB, based on first-order ordinary differential equations, performing numerical simulations and sensitivity analysis. Furthermore, as input parameters of the model, experimental data from patients affected by Alzheimer's disease, frontotemporal dementia, mild cognitive impairment and matched neurological controls were used, with the aim of investigating the differences between physiological and pathological conditions in the regulation of iron passage between blood and CSF which can be possibly targeted by therapy.

Abstract
Human serine protease inhibitors (serpins) are the main inhibitors of serine proteases, but some of them also have the capability to effectively inhibit cysteine proteases. Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) main protease (Mpro) is a chymotrypsin-type cysteine protease that is needed to produce functional proteins essential for virus replication and transcription. Serpin traps its target proteases by presenting a reactive center loop (RCL) as protease-specific cleavage site, resulting in protease inactivation. Mpro target sites with its active site serine and other flanking residues can possibly interact with serpins. Alternatively, RCL cleavage site of serpins with known evidence of inhibition of cysteine proteases can be replaced by Mpro target site to make chimeric proteins. Purified chimeric serpin can possibly inhibit Mpro that can be assessed indirectly by observing the decrease in ability of Mpro to cleave its chromogenic substrate. Chimeric serpins with best interaction and active site binding and with ability to form 1:1 serpin-Mpro complex in human plasma can be assessed by using SDS/PAGE and Western blot analysis with serpin antibody. Trapping SARS-CoV-2 Mpro cysteine protease using cross-class serpin cysteine protease inhibition activity is a novel idea with significant therapeutic potential.

Abstract
Heparin cofactor II (HCII) is predominantly expressed in the liver and inhibits thrombin in blood plasma to influence the blood coagulation cascade. Its deficiency is associated with arterial thrombosis. Its cleavage by neutrophil elastase produces fragment that helps in neutrophil chemotaxis in the acute inflammatory response in human. In the present study, we have identified a novel alternatively spliced transcript of the HCII gene in human liver. This novel transcript includes an additional novel region in continuation with exon 3 called exon 3b. Exon 3b acts like an alternate last exon, and hence its inclusion in the transcript due to alternative splicing removes exon 4 and encodes for a different C-terminal region to give a novel protein, HCII-N. MD simulations of HCII-N and three-dimensional structure showed a unique 51 amino acid sequence at the C-terminal having unique RCL-like structure. The HCII-N protein purified from bacterial culture showed a protein migrating at lower molecular weight (MW 55 kDa) as compared to native HCII (MW 66 kDa). A fluorescence-based analysis revealed a more compact structure of HCII-N that was in a more hydrophilic environment. The HCII-N protein, however, showed no inhibitory activity against thrombin. Due to large conformational variation observed in comparison with native HCII, HCII-N may have alternate protease specificity or a non-inhibitory role. Western blot of HCII purified from large plasma volume showed the presence of a low MW 59 kDa band with no thrombin activity. This study provides the first evidence of alternatively spliced novel isoform of the HCII gene.

Abstract
Neuroserpin (NS) is predominantly expressed in brain and inhibits tissue-type plasminogen activator (tPA) with implications in brain development and memory. Nature of conformational change in pathological variants in strand 6B and helix B of NS that cause a relatively mild to severe epilepsy (and/or dementia) remains largely elusive. MD simulation with wild type (WT) NS, strand 6B and helix B variants indicated that substitution in this region affects the conformation of the strands 5B, 5A and reactive centre loop. Therefore, we designed variants of NS in strand 6B (I46D and F48S) and helix B (A54F, L55A and L55P) to investigate their role in tPA inhibition mechanism and propensity to aggregate. An interaction analysis showed disturbance of a hydrophobic patch centered at strands 5B, 6B and helix B in I46D and F48S but not in A54F, L55A, L55P and WT NS. Purified I46D, F48S and L55P variants showed decrease in fluorescence emission intensity but have similar α-helical content, however results of A54F and L55A were comparable to WT NS. Analysis of tPA inhibition showed marginal effect on A54F and L55A variant with tPA-NS complex formation. In contrast, I46D, F48S and L55P variants showed massive decrease in tPA inhibition, with no tPA-NS complex formation. Analysis of native PAGE under under polymerization condition showed prompt conversion of I46D, F48S and L55P to latent conformation but not A54F and L55A variants. Identification of these novel conformational changes will aid in the understanding of variable clinical phenotype of shutter region NS variants and other serpins.

Abstract
Periconceptional folic acid is known to have a major role in the prevention of neural tube defects, leading to global recommendations for folic acid supplementation before and in early pregnancy. Maternal folate throughout pregnancy may have other roles in offspring health, including neurodevelopment and cognitive performance in childhood. Folate and folic acid (vitamin B9) act as a co-enzyme essential for single carbon metabolism, a network of pathways involved in several biological processes including nucleotide synthesis, DNA repair, and methylation reactions. In general, rapidly growing and multiplying cells require an adequate supply of folate. A primary deficiency of natural folate resulting in an increase of the total homocysteine concentration may be detrimental to the quality of the oocyte, subsequent fertilisation, embryogenesis, implantation, and fetal development. However, to date, folate-methionine metabolism and folate transport have not been studied in developing buffalo embryos. The present study details transcript expression for genes encoding key enzymes in the linked folate-methionine cycles in the ovary tissue, cumulus cells, immature oocytes, IVM oocytes, and pre-implantation embryos and also estimates the folate concentration in follicular fluid (FF) of buffalo. The FF was pooled and collected by aspiration of different sizes of surface follicles (2-8mm diameter). The total number of analysed samples was three, with different dilutions and estimation of folate in FF of buffalo done by chemiluminescence assay. Total RNA was extracted from oocytes, cumulus cells, ovarian tissue, and embryos produced from IVF. RT-PCR was performed to analyse the expression of folate-methionine cycle enzymes and folate transporters. Transcripts for all the enzymes of the folate-methionine cycle (i.e. SHMT, MTR, MTRR, MAT1A, MAT2B, GNMT, AHCY, CBS, and DHFR) and folate transporters (FOLR1, FOLR2) and reduced folate carrier (SLC19A1) were expressed in ovarian tissue, cumulus cells, oocytes, and pre-implantation embryos. Immunocytochemical analysis revealed FOLR2 and SLC19A1 protein expression on the plasma membrane and/or cytoplasm of the oocytes and embryos, and FOLR1 in the nucleus of pre-implantation embryos. The folate concentration in FF was 24ngmL−1. This is the first report to examine the concentration of folate in FF and revealed the identification of transcripts in different samples of buffalo species. The presence of these enzymes could have a profound effect on single-carbon metabolism within the ovary and pre-implantation embryo, therefore indicating that folate from FF is being disseminated through folate receptors within oocytes and embryos to participate in the folate pathway. This study advocates the necessity for examination of the result of folate supplementation throughout invitro embryo production for improving the quality and quantity of transferable blastocysts and subsequently live calf births in buffalo.

Abstract
The present study was carried out to isolate mesenchymal stem cells (MSCs) from adipose tissue of cattle (Bos indicus), characterise them, and apply them for the treatment of mastitis and metritis in the cow. Cattle MSCs were isolated from adipose tissue near the loin region of cow. Isolated adipose tissue was subjected to enzymatic digestion using 2% collagenase with agitation at regular intervals. The cells obtained after digestion were resuspended in cell culture flasks containing growth enriched medium and cultured under standard culture conditions. Alkaline phosphatase staining was used as one of the parameters to confirm cultured putative MSCs. Bovine Ad-MSCs were further characterised using real time-PCR by amplification of MSC-specific markers: CD73, CD90, and CD105 as positive markers and CD34, CD45, and CD79a as negative markers. Immunocytochemistry showed the presence of CD73, CD90, and CD105 on the cell surface. Three groups-control (C), local (L), and intravenous (IV)-with 6 cows suffering from mastitis were taken in each group and subjected to MSC transplantation through local and intravenous routes. Control group animals were subjected to antibiotic treatment only. Similarly, another three groups were taken with 6 cows in each group suffering from metritis. Post-transplantation wound healing, tissue repair, and reduction in inflammation were monitored for 26 days, at different time intervals; that is, after Days 1, 3, 7, and 15. Blood samples were also collected from animals at the same time intervals for real time-PCR. A similar examination was also done in metritis groups along with the analysis of the reduction in turbidity of cervical fluid at the abovementioned time intervals. Real time-PCR was performed to determine relative expression of genes for proliferative factors, anti-inflammatory cytokines, and antimicrobial peptides on cells isolated from blood collected at different time intervals. Gene expression in the local group of mastitis subjected to MSC injection was significantly higher than that of the IV and control group. The somatic cell count declined in both local and IV groups compared with the control group. Whereas the expression of the same genes in the IV group of metritis was significantly higher than that of the local and control groups of cows. The turbidity of cervical fluid and mucus was reduced in the IV group compared with the local group. In conclusion, we demonstrated the healing potential of MSCs in a cow model via MSC injection. Promising results were obtained in curing mastitis in both local and IV groups, whereas healing in the case of metritis was significantly higher in the IV group compared with both the control and local groups of cows. The study indicates the potential use of MSc for treatment of mastitis and metritis in cattle through wound healing and decreasing microbial infection.

Abstract
Onychomycosis is considered a fungal nail infection caused mainly by dermatophytes, yeasts and non-dermatophyte molds including dematiaceous fungi. Onychomycosis caused by non-dermatophyte molds is a health problem in the medical environment as the patients frequently return to outpatient clinics seeking new therapeutic modalities. Here, we report the first case of onychomycosis caused by a black fungus, Neoscytalidium novaehollandiae, in the right hand finger nail of a 52-year-old Iranian female with no history of immunodeficiency and underlying disease. The pattern of nail involvement was recognized as total dystrophic onychomycosis. Examination of nail scrapings with potassium hydroxide revealed brown, septate and branching sub-hyaline to dark-colored hyphae. The black fungus isolated in culture was identified as Neoscytalidium novaehollandiae by molecular analysis. The patient received oral terbinafine plus ciclopirox nail lacquer twice a week and began responding to the treatment three months after initial antifungal therapy. Additional four weeks' use of terbinafine plus ciclopirox nail lacquer completely resolved the clinical manifestations of onychomycosis. After four months, both microscopy and culture were negative.

Abstract
BACKGROUND Birds are considered as a reservoir for pathogenic and non-pathogenic fungi. Pigeon droppings have the potential for spreading these fungi to the environment. Cryptococcus species are important fungi associated with pigeon droppings. In this regard, there are many types of yeast associated with guano that is important for human and animal health. AIMS The main objective of this study is the identification of non-Cryptococcus yeasts isolated from pigeon dropping in Shiraz, Southern Iran. METHODS A total of 100 unknown yeasts, which were previously screened and identified as non-Cryptococcus from pigeon guano through the conventional methods, were used in this study. Identification of the isolates was performed based on conventional methods and DNA sequence analysis of internal transcribed spacer (ITS) rDNA gene region. The sequence results were deposited in NCBI database using the Basic Local Alignment Search Tool (BLAST). RESULTS A total of 16 species belonging to 7 genera were identified as Candida spp. 51% (8 species), Rhodotorula sp. 24%, Trichosporon spp. 21% (3 species), Rhodosporidium 2%, Saccharomyces 1%, Rhizoctonia 1%, and Meyerozyma 1%. The predominant isolates were Rhodotorula rubra (24%), Candida famata (20%), and Trichosporon asahii (13%). The other species were Rhodosporidium kratochvilovae 2 (2%), Saccharomyces cerevisiae 1 (1%), Rhizoctonia solani 1 (1%), and Meyerozyma caribbica 1 (1%). CONCLUSION Pigeon excreta examined in this study were associated with several kinds of opportunistic yeasts which could cause diseases in prone human and animals.

Abstract
OBJECTIVE Cryptococcosis is a major opportunistic fungal infection caused by members of the genus Cryptococcus, mainly those belonging to the Cryptococcus neoformans/Cryptococcus gattii species complexes. Here, we report a comprehensive molecular epidemiological study of the environmental distribution of Cryptococcus isolates in Shiraz, Iran with review of litreature. METHOD A total of 406 samples were obtained from Eucalyptus trees and 139 samples from pigeon droppings. Cryptococcus species identification and genotyping were performed by amplified fragment length polymorphism (AFLP) fingerprinting sequencing and sequencing of the ITS rDNA region. RESULTS Majority of the isolates belonged to the Naganishia taxon (n=69) including N. albida (formerly C. albidus, n=62), N. globosa (formerly C. saitoi, n=4), N. adeliensis (formerly C. adeliensis, n=2), N. diffluens (formerly C. diffluens, n=1), and the identified C. neoformans isolates (n=25) belonged to genotype AFLP1/VNI (n=22) and AFLP1B/VNII (n=3). CONCLUSION More research efforts should be employed to isolate C. gattii species complex from environmental niches in Iran and provide additional evidence related to novel molecular types.

Abstract
OBJECTIVES Patients with Amyotrophic Lateral Sclerosis (ALS) have expressed desire to become living organ donors but are unable to do so with current organ donation policies. Our objective is to assess ALS patient's interest in organ donation, and perceived concerns of this practice by ALS neurologists. PATIENTS AND METHODS An electronic survey was administered to ALS neurologists across the United States regarding living organ donation in ALS patients prior to respiratory failure. RESULTS 52 complete responses were received from 121 invites. 67% (35/52) of neurologists expressed no concerns about living organ donation in ALS patients, and 33% had concerns. The concerns related to respiratory failure, anesthesia exposure and renal dysfunction. With their concerns addressed, 71% of neurologists reported that they would endorse living organ donation. 49% of neurologists reported being asked by a patient for information regarding living organ donation. ALS neurologists felt that 22.8% of ALS patients (median 19%) would be interested in learning more about organ donation, while only 6% of neurologists broach this subject with their patients. CONCLUSION Our results indicate that 1 in every 4 ALS patients may be interested in exploring options for living organ donation, and this topic is not routinely addressed by ALS clinics. These results indicate an unexplored area of patient interest. To honor a patient's wishes to donate, the transplant community will have to accommodate living organ donation from terminally ill patients, and address neurologist concerns. Such a practice could benefit two groups of patients.

Abstract
Background and Purpose: Vulvovaginal candidiasis is a frequent disease affecting approximately more than %75 of all childbearing women at least once in their lifetime by overgrowth of opportunistic Candida species. Recurrent vulvovaginal candidiasis (RVVC) is common in otherwise healthy individuals. Several risk factors were reported to contribute to RVVC susceptibility. A polymorphism in Dectin-1 (Y238X, rs16910526 ) was identified in patients with RVVC and hypothesized that genetic factors play an important role in susceptibility to RVVC. Herein, we aimed to survey the polymorphisms in the Dectin-1 gene, linked to susceptibility to RVVC. Materials and Methods: In the current study, blood samples were obtained from 25 patients who had frequent vulvovaginal candidiasis relapses and were diagnosed as RVVC. In addition, blood cultures were obtained from control group comprising of healthy individuals (n=25) with no history of RVVC, vaginal discharge, or itching on the day of examination. Dectin-1 Y238X gene polymorphism was investigated using Bi-PASA and DNA sequencing. Results: The analysis revealed that all of the patients were wild-type homozygous for Dectin-1 Y238X polymorphisms. None of the individuals showed heterozygous or mutant homozygous Dectin-1 polymorphism. Conclusion: No significant correlations were observed between the susceptibility to RVVC and Dectin-1 Y238X polymorphism in the Iranian population, which was not previously studied.

Abstract
Primary hyperparathyroidism (PHPT) is a rare etiology of hypercalcemia-induced pancreatitis, contributing about 0.4% to 1.5% of cases in the general population and up to 13% of cases during pregnancy. PHPT that occurs during pregnancy is a challenging diagnosis as the physiological changes in calcium homeostasis mask the symptoms of hypercalcemia. PHPT during pregnancy often remains undiagnosed and untreated, and may result in serious clinical implications for the mother and fetus. Most clinicians consider surgery within the second trimester of pregnancy as the treatment of choice in this group of patients. This article refers to a case of a 24-year married woman in whom PHPT was diagnosed for the first time in postpartum period. She succumbed to complications on Day 20 postpartum. Pathological findings revealed metastatic calcification in lungs, pancreas and uterine vessels, chronic pancreatitis and renal cortical necrosis.

Abstract
CONCLUSION The average SNOT 22 score should be calculated locally and be used as a reference when managing patients with nasal symptoms. OBJECTIVE To calculate the average Sino Nasal Outcome Test (SNOT) 22 score across Lanarkshire and to compare it with similar studies. METHODOLOGY Prospective data collection in which SNOT 22 forms were filled by the Lanarkshire population who had no history of sinonasal disease. Participants included patient attendants and hospital staff across multiple hospital sites in NHS Lanarkshire. All patients with hay fever, previous nasal surgeries, or any history of use of topical steroid sprays were excluded from the study. RESULTS This study included 118 participants, out of which three had to be excluded due to unclear data entry. The total number for SNOT forms included for analysis was 115. This included 85 females and 29 males, while one form remained unanswered. The mean age was 49 (range = 15-81) years. The mean SNOT 22 score was 18 (range = 0-89).
