Abstract
The detection and quantification of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus particles in ambient waters using a membrane-based in-gel loop-mediated isothermal amplification (mgLAMP) method can play an important role in large-scale environmental surveillance for early warning of potential outbreaks. However, counting particles or cells in fluorescence microscopy is an expensive, time-consuming, and tedious task that only highly trained technicians and researchers can perform. Although such objects are generally easy to identify, manually annotating cells is occasionally prone to fatigue errors and arbitrariness due to the operator's interpretation of borderline cases. In this research, we proposed a method to detect and quantify multiscale and shape variant SARS-CoV-2 fluorescent cells generated using a portable (mgLAMP) system and captured using a smartphone camera. The proposed method is based on the YOLOv5 algorithm, which uses CSPnet as its backbone. CSPnet is a recently proposed convolutional neural network (CNN) that duplicates gradient information within the network using a combination of Dense nets and ResNet blocks, and bottleneck convolution layers to reduce computation while at the same time maintaining high accuracy. In addition, we apply the test time augmentation (TTA) algorithm in conjunction with YOLO's one-stage multihead detection heads to detect all cells of varying sizes and shapes. We evaluated the model using a private dataset provided by the Linde + Robinson Laboratory, California Institute of Technology, United States. The model achieved a mAP@0.5 score of 90.3 in the YOLOv5-s6.

Abstract
Steroids are neuroprotective and a growing body of evidence indicates that mitochondria are a potential target of their effects. The mitochondria are the site of cellular energy synthesis, regulate oxidative stress and play a key role in cell death after brain injury and neurodegenerative diseases. After providing a summary of the literature on the general functions of mitochondria and the effects of sex steroid administrations on mitochondrial metabolism, we summarise and discuss our recent findings concerning sex differences in brain mitochondrial function under physiological and pathological conditions. To analyse the influence of endogenous sex steroids, the oxidative phosphorylation system, mitochondrial oxidative stress and brain steroid levels were compared between male and female mice, either intact or gonadectomised. The results obtained show that females have higher a mitochondrial respiration and lower oxidative stress compared to males and also that these differences were suppressed by ovariectomy but not orchidectomy. We have also shown that the decrease in brain mitochondrial respiration induced by ischaemia/reperfusion is different according to sex. In both sexes, treatment with progesterone reduced the ischaemia/reperfusion-induced mitochondrial alterations. Our findings indicate sex differences in brain mitochondrial function under physiological conditions, as well as after stroke, and identify mitochondria as a target of the neuroprotective properties of progesterone. Thus, it is necessary to investigate sex specificity in brain physiopathological mechanisms, especially when mitochondria impairment is involved.

Abstract
Lipoic acid (LA) is the cofactor of the E2 subunit of mitochondrial ketoacid dehydrogenases and plays a major role in oxidative decarboxylation. De novo LA biosynthesis is dependent on LIAS activity together with LIPT1 and LIPT2. LIAS is an iron‑sulfur (Fe-S) cluster-containing mitochondrial protein, like mitochondrial aconitase (mt-aco) and some subunits of respiratory chain (RC) complexes I, II and III. All of them harbor at least one [Fe-S] cluster and their activity is dependent on the mitochondrial [Fe-S] cluster (ISC) assembly machinery. Disorders in the ISC machinery affect numerous Fe-S proteins and lead to a heterogeneous group of diseases with a wide variety of clinical symptoms and combined enzymatic defects. Here, we present the biochemical profiles of several key mitochondrial [Fe-S]-containing proteins in fibroblasts from 13 patients carrying mutations in genes encoding proteins involved in either the lipoic acid (LIPT1 and LIPT2) or mitochondrial ISC biogenesis (FDX1L, ISCA2, IBA57, NFU1, BOLA3) pathway. Ten of them are new patients described for the first time. We confirm that the fibroblast is a good cellular model to study these deficiencies, except for patients presenting mutations in FDX1L and a muscular clinical phenotype. We find that oxidative phosphorylation can be affected by LA defects in LIPT1 and LIPT2 patients due to excessive oxidative stress or to another mechanism connecting LA and respiratory chain activity. We confirm that NFU1, BOLA3, ISCA2 and IBA57 operate in the maturation of [4Fe-4S] clusters and not in [2Fe-2S] protein maturation. Our work suggests a functional difference between IBA57 and other proteins involved in maturation of [Fe-S] proteins. IBA57 seems to require BOLA3, NFU1 and ISCA2 for its stability and NFU1 requires BOLA3. Finally, our study establishes different biochemical profiles for patients according to their mutated protein.

Abstract
BACKGROUND Although lung transplantation is a well-accepted treatment for end-stage lung diseases patients, only 15%-20% of the brain-dead donors' lungs are usable for transplantation. This results in high mortality of candidates on waiting lists. Ex-vivo lung perfusion (EVLP) is a novel method for better evaluation of a potential lung for transplantation. OBJECTIVE To report the first experience of EVLP in Iran. METHODS The study included a pig in Vienna Medical University, Vienna, Austria, and 4 humans in Masih Daneshvari Hospital, Tehran, Iran. All brain-dead donors from 2013 to 2015 in Tehran were evaluated for EVLP. Donors without signs of severe chest trauma or pneumonia, with poor oxygenation were included. RESULTS An increasing trend in difference between the pulmonary arterial pO2 and left atrial pO2, an increasing pattern in dynamic lung compliance, and a decreasing trend in the pulmonary vascular resistance, were observed. CONCLUSION The initial experience of EVLP in Iran was successful in terms of important/critical parameters. The results emphasize on some important considerations such as precisely following standard lung harvesting and monitoring temperature and pressure. EVLP technique may not be a cost-effective option for low-income countries at first glance. However, because this is the only therapeutic treatment for end-stage lung disease, it is advisable to continue working on this method to find alternatives with lesser costs.

Abstract
Mitochondrial neurogastrointestinal encephalopathy disease (MNGIE) is a rare autosomal-recessive syndrome, resulting from mutations in the TYMP gene, located at 22q13. The mutation induces a thymidine phosphorylase (TP) deficit, which leads to a nucleotide pool imbalance and to instability of the mitochondrial DNA. The clinical picture regroups gastrointestinal dysmotility, cachexia, ptosis, ophthalmoplegia, peripheral neuropathy, and asymptomatic leukoencephalopathy. The prognosis is unfavorable. We present the case of a 14-year-old Caucasian female whose symptoms started in early childhood. The diagnosis was suspected after magnetic resonance imaging (MRI), performed given the atypical features of mental anorexia, which revealed white matter abnormalities. She presented chronic vomiting, postprandial abdominal pain, and problems gaining weight accompanied by cachexia. This diagnosis led to establishing proper care, in particular an enteral and parenteral nutrition program. There is no known specific effective treatment, but numerous studies are in progress. In this article, after reviewing the existing studies, we discuss the main diagnostic and therapeutic aspects of the disease. We argue for the necessity of performing a cerebral MRI given the atypical features of a patient with suspected mental anorexia (or when the clinical pattern of a patient with mental anorexia seems atypical), so that MNGIE can be ruled out.

Abstract
OBJECTIVE To compare the perception of benign prostatic hypertrophy (BPH) between patients and general practitioners (GPs) in terms of severity and evolution of symptoms and medication adherence. METHODOLOGY A cross-sectional observational study was performed in France in a sample of GPs who included patients for whom a BPH treatment was prescribed. Data were collected on patient and GP characteristics, diagnosis, BPH management, severity and evolution of symptoms and medication adherence. RESULTS One thousand and ninety-eight patients were recruited by 247 GPs. In 87.4% of cases, diagnosis was performed by GPs. Among them, 82.7% of patients were treated by monotherapy. The choice of a treatment was mainly based on treatment efficacy and the patient's opinion was taken into account by 5% of GPs. The patient's evaluation of symptoms severity was consistent with the GP's in 53.9% of cases. A worsening of symptoms was reported significantly more frequently by patients (18.5%) than by GPs (8.8%). Among 94 patients who reported poor adherence, GPs estimated that the level of medication adherence was good for 72 of these (77%). CONCLUSION There was discordance between the evaluation made by GPs and by patients on the perception of BPH symptoms and medication adherence. The patient's opinion was rarely taken into account in the therapeutic decision, reflecting a lack of shared medical decision-making, which would be helpful for the physician in order to optimize BPH management.

Abstract
Mitochondrial complex I is the largest multi-protein enzyme complex of the oxidative phosphorylation system. Seven subunits of this complex are encoded by the mitochondrial and the remainder by the nuclear genome. We review the natural disease course and signs and symptoms of 130 patients (four new cases and 126 from literature) with mutations in nuclear genes encoding structural complex I proteins or those involved in its assembly. Complex I deficiency caused by a nuclear gene defect is usually a non-dysmorphic syndrome, characterized by severe multi-system organ involvement and a poor prognosis. Age at presentation may vary, but is generally within the first year of life. The most prevalent symptoms include hypotonia, nystagmus, respiratory abnormalities, pyramidal signs, dystonia, psychomotor retardation or regression, failure to thrive, and feeding problems. Characteristic symptoms include brainstem involvement, optic atrophy and Leigh syndrome on MRI, either or not in combination with internal organ involvement and lactic acidemia. Virtually all children ultimately develop Leigh syndrome or leukoencephalopathy. Twenty-five percent of the patients died before the age of six months, more than half before the age of two and 75 % before the age of ten years. Some patients showed recovery of certain skills or are still alive in their thirties . No clinical, biochemical, or genetic parameters indicating longer survival were found. No clear genotype-phenotype correlations were observed, however defects in some genes seem to be associated with a better or poorer prognosis, cardiomyopathy, Leigh syndrome or brainstem lesions.

Abstract
Ex vivo lung perfusion (EVLP) provides the ability to evaluate donor lungs before transplantation. Yet, limited prospective clinical data exist with regard to its potential to recondition unacceptable donor lungs. This paper summarizes the results of a prospective study of lung transplantation using only initially unacceptable donor lungs, which were improved by EVLP for 2-4 h. From March 2010-June 2011, 13 lungs were evaluated ex vivo. Median donor PaO(2) at FiO(2) 1.0/PEEP5 was 216 mmHg (range 133-271). Four lungs, all with trauma history, showed no improvement and were discarded. Nine lungs improved to a ΔPO(2) higher than 350 mmHg. Median PvO(2) at final assessment in these lungs was 466 mmHg (range 434-525). These lungs were transplanted with a median total ischemic time of 577 min (range 486-678). None of the patients developed primary graft dysfunction grades 2 or 3 within 72 h after transplantation. One patient with secondary pulmonary hypertension was left on a planned prolonged extracorporeal membrane oxygenation postoperatively. Median intubation time was 2 days. Thirty-day mortality was 0%. During the observation period, 119 patients received standard lung transplantation with comparable perioperative outcome. EVLP has a significant potential to improve the quality of otherwise unacceptable donor lungs.

Complex I deficiency, a major cause of respiratory chain dysfunction, accounts for various clinical presentations, including Leigh syndrome. Human complex I comprises seven core subunits encoded by mitochondrial DNA (mtDNA) and 38 core subunits encoded by nuclear DNA (nDNA). Moreover, its assembly requires six known and many unknown assembly factors. To date, no correlation between genotypes and brain MRI phenotypes has been found in complex I deficiencies. DESIGN AND SUBJECTS The brain MRIs of 30 patients carrying known mutation(s) in genes involved in complex I were retrospectively collected and compared with the brain MRIs of 11 patients carrying known mutations in genes involved in the pyruvate dehydrogenase (PDH) complex as well as 10 patients with MT-TL1 mutations. RESULTS All complex I deficient patients showed bilateral brainstem lesions (30/30) and 77% (23/30) showed anomalies of the putamen. Supratentorial stroke-like lesions were only observed in complex I deficient patients carrying mtDNA mutations (8/19) and necrotising leucoencephalopathy in patients with nDNA mutations (4/5). Conversely, the isolated stroke-like images observed in patients with MT-TL1 mutations, or the corpus callosum malformations observed in PDH deficient patients, were never observed in complex I deficient patients. CONCLUSION A common pattern of brain MRI imaging was identified with abnormal signal intensities in brainstem and subtentorial nuclei with lactate peak as a clue of complex I deficiency. Combining clinico-biochemical data with brain imaging may therefore help orient genetic studies in complex I deficiency.

Abstract
INTRODUCTION Ghost cell odontogenic carcinoma is a rare malignant tumor that occurs both in the mandible and maxilla. It has a variable non-specific clinical and radiological appearance. The authors report a mandibular case. CASE REPORT A 89-year-old man consulted for swelling of the left lower mandible and gums having developed over the previous 8 months. The lesion was 6cm long, ulcerative and budding, bleeding on contact. Radiological assessment revealed blurred contour osteolysis with extension to the mouth floor and sub-mandibular compartment. Histological examination of the surgical piece supported the diagnosis of ghost cell odontogenic carcinoma. The tumor recurred 2 months later and the patient died 6 months after surgery. DISCUSSION Ghost cell odontogenic carcinoma is a rare lesion. The patient was very old. Clinical and radiographic signs were unspecific. Histopathology proved the diagnosis. Evolution was unpredictable due to the wide spectrum of growth patterns. Extensive radical surgery is mandatory due to the high risk of recurrence.

Abstract
The effect of transurethral resection of the prostate (TURP) on erectile function is still controversial, and available evidence is conflicting. One of the possible mechanisms of post-TURP erectile dysfunction (ED) is direct thermal injury to the erectile nerves. The aim of this study was to investigate the effect of TURP on erectile function. Fifty patients undergoing TURP for obstructive benign prostatic hyperplasia (HBP) were prospectively included in the study, and 50 age-matched patients undergoing transurethral resection of the superficial bladder tumor were also prospectively included as a control group. All patients completed the international index of erectile function (IIEF-15), the international prostatic symptom score (IPSS) and the Hospital Anxiety and Depression Scale at inclusion in the study and then at the 3- and 6-month follow-up evaluation. Capsular perforations during TURP were prospectively reported by the operating surgeon. There was a significant improvement of erectile function in the TURP group despite the onset of ejaculation disorders in 70% of the patients. Improvement of erectile function was also found in the subgroup of patients with capsular perforation during TURP. Comparison with the control group showed that at preoperative evaluation, patients in the TURP group had more severe urinary symptoms and worse erectile function than did those of the control group. At the postoperative period, the IPSS score became comparable in the two groups, with major improvement of erectile function in the TURP group. We concluded that TURP improved erectile function in HBP patients with severe urinary symptoms. This improvement of erectile function was observed even in case of capsular perforation.

Abstract
This study determined the prevalence of inherited factor V Leiden mutation in a group of 128 thrombosis patients (102 with venous thrombosis and 26 with arterial thrombosis) attending a hospital in Sousse, Tunisia, and a control group of 100 with no history of thrombosis. Using an allele-specific PCR amplification technique, factor V Leiden was found in significantly more patients (20.3%) than controls (6.0%). The higher prevalence was significant in the subgroup of venous thrombosis patients but not in arterial thrombosis patients. The allele frequency was 3.5% in the normal Tunisian population. Screening Tunisian patients with venous thrombosis and their relatives for factor V Leiden may be justified.

Abstract
Deoxyguanosine kinase (dGK) deficiency is a frequent cause of mitochondrial DNA depletion associated with a hepatocerebral phenotype. In this study, we describe a new splice site mutation in the DGUOK gene and the clinical, radiologic, and genetic features of these DGUOK patients. This new DGUOK homozygous mutation (c.444-62C>A) was identified in three patients from two North-African consanguineous families with combined respiratory chain deficiencies and mitochondrial DNA depletion in the liver. Brain MRIs are normal in DGUOK patients in the literature. Interestingly, we found subtentorial abnormal myelination and moderate hyperintensity in the bilateral pallidi in our patients. This new mutation creates a cryptic splice site in intron 3 (in position -62) and is predicted to result in a larger protein with an in-frame insertion of 20 amino acids. In silico analysis of the putative impact of the insertion shows serious clashes in protein conformation: this insertion disrupts the alpha5 helix of the dGK kinase domain, rendering the protein unable to bind purine deoxyribonucleosides. In addition, a common haplotype that segregated with the disease in both families was detected by haplotype reconstruction with 10 markers (microsatellites and SNPs), which span 4.6 Mb of DNA covering the DGUOK locus. In conclusion, we report a new DGUOK splice site mutation that provide insight into a critical protein domain (dGK kinase domain) and the first founder mutation in a North-African population.

Abstract
Diversity of respiratory chain spectrophotometric assays may lead to difficult comparison of results between centers. The French network of mitochondrial diseases diagnostic centers undertook comparison of the results obtained with different protocols in the French diagnostic centers. The diversity of protocols was shown to have striking consequences, which prompted the network to undertake standardization and optimization of the protocols with respect to clinical diagnosis, i.e. high velocity while maintaining linear kinetics relative to time and enzyme concentration. Assays were set up on animal tissues and verified on control human muscle and fibroblasts. Influence of homogenization buffer and narrow range of optimal concentration of phosphate, substrate and tissue were shown. Experimental data and proposed protocols have been posted on a free access website. Their subsequent use in several diagnostic centers has improved consistency for all assays.
