Abstract
The aim of this study was the determination of the chemical compounds of Lavandula stoechas essential oil from Aknol (LSEOA), Khenifra (LSEOK), and Beni Mellal (LSEOB), and the in vitro investigation of their antibacterial, anticandidal, and antioxidant effects, and in silico anti-SARS-CoV-2 activity. The chemical profile of LSEO was determined using GC-MS-MS analysis, the results of which showed a qualitative and quantitative variation in the chemical composition of volatile compounds including L-fenchone, cubebol, camphor, bornyl acetate, and τ-muurolol; indicating that the biosynthesis of essential oils of Lavandula stoechas (LSEO) varied depending on the site of growth. The antioxidant activity was evaluated using the ABTS and FRAP methods, our results showed that this tested oil is endowed with an ABTS inhibitory effect and an important reducing power which varies between 4.82 ± 1.52 and 15.73 ± 3.26 mg EAA/g extract. The results of antibacterial activity of LSEOA, LSEOK and LSEOB, tested against Gram-positive and Gram-negative bacteria, revealed that B. subtilis (20.66 ± 1.15-25 ± 4.35 mm), P. mirabilis (18.66 ± 1.15-18.66 ± 1.15 mm), and P. aeruginosa (13.33 ± 1.15-19 ± 1.00 mm) are the most susceptible strains to LSEOA, LSEOK and LSEOB of which LSEOB exhibits bactericidal effect against P. mirabilis. furthermore The LSEO exhibited varying degrees of anticandidal activity with an inhibition zones of 25.33 ± 0.5, 22.66 ± 2.51, and 19 ± 1 mm for LSEOK, LSEOB, and LSEOA, respectively. Additionally, the in silico molecular docking process, performed using Chimera Vina and Surflex-Dock programs, indicated that LSEO could inhibit SARS-CoV-2. These important biological properties of LSEO qualify this plant as an interesting source of natural bioactive compounds with medicinal actions.

Abstract
Owing to the large genetic diversity of barley and its resilience under harsh environments, this crop is of great value for agroecological transition and the need for reduction of nitrogen (N) fertilizers inputs. In the present work, we investigated the diversity of a North African barley genotype collection in terms of growth under limiting N (LN) or ample N (HN) supply and in terms of physiological traits including amino acid content in young seedlings. We identified a Moroccan variety, Laanaceur, accumulating five times more lysine in its leaves than the others under both N nutritional regimes. Physiological characterization of the barley collection showed the genetic diversity of barley adaptation strategies to LN and highlighted a genotype x environment interaction. In all genotypes, N limitation resulted in global biomass reduction, an increase in C concentration, and a higher resource allocation to the roots, indicating that this organ undergoes important adaptive metabolic activity. The most important diversity concerned leaf nitrogen use efficiency (LNUE), root nitrogen use efficiency (RNUE), root nitrogen uptake efficiency (RNUpE), and leaf nitrogen uptake efficiency (LNUpE). Using LNUE as a target trait reflecting barley capacity to deal with N limitation, this trait was positively correlated with plant nitrogen uptake efficiency (PNUpE) and RNUpE. Based on the LNUE trait, we determined three classes showing high, moderate, or low tolerance to N limitation. The transcriptomic approach showed that signaling, ionic transport, immunity, and stress response were the major functions affected by N supply. A candidate gene encoding the HvNRT2.10 transporter was commonly up-regulated under LN in the three barley genotypes investigated. Genes encoding key enzymes required for lysine biosynthesis in plants, dihydrodipicolinate synthase (DHPS) and the catabolic enzyme, the bifunctional Lys-ketoglutarate reductase/saccharopine dehydrogenase are up-regulated in Laanaceur and likely account for a hyperaccumulation of lysine in this genotype. Our work provides key physiological markers of North African barley response to low N availability in the early developmental stages.

Abstract
The present study has been undertaken in order to highlight the healing effect of Zizyphus lotus vegetable oil. The seeds of this plant contain an oil rate of 30%. The obtained results on the main elements composing the vegetable oil have shown that Zizyphus lotus vegetable oil has a low value of acidity index and it presents a not negligible degree of unsaturation. The value of the peroxide index of Zizyphus lotus vegetable oil is less than 10 which characterizes the most of conventional oils. Furthermore, the spectral analysis by gas chromatography has shown the presence of 53 majority and minority molecules. Thus, the evaluation of the healing activity of Z. lotus seed vegetable oil has demonstrated a highly significant effect against the negative control and silver sulfadiazine was used as conventional treatment for burns. Based on the obtained results, we can suggest that the oil extracted from the seeds of the studied plant could be used to cure wounds.

Abstract
Conversion therapy is a set of practices that aim to change or alter an individual's sexual orientation or gender identity. It is premised on a belief that an individual's sexual orientation or gender identity can be changed and that doing so is a desirable outcome for the individual, family, or community. Other terms used to describe this practice include sexual orientation change effort (SOCE), reparative therapy, reintegrative therapy, reorientation therapy, ex-gay therapy, and gay cure. Conversion therapy is practiced in every region of the world. We have identified sources confirming or indicating that conversion therapy is performed in over 60 countries. In those countries where it is performed, a wide and variable range of practices are believed to create change in an individual's sexual orientation or gender identity. Some examples of these include: talk therapy or psychotherapy (e.g., exploring life events to identify the cause); group therapy; medication (including anti-psychotics, anti- depressants, anti-anxiety, and psychoactive drugs, and hormone injections); Eye Movement Desensitization and Reprocessing (where an individual focuses on a traumatic memory while simultaneously experiencing bilateral stimulation); electroshock or electroconvulsive therapy (ECT) (where electrodes are attached to the head and electric current is passed between them to induce seizure); aversive treatments (including electric shock to the hands and/or genitals or nausea-inducing medication administered with presentation of homoerotic stimuli); exorcism or ritual cleansing (e.g., beating the individual with a broomstick while reading holy verses or burning the individual's head, back, and palms); force-feeding or food deprivation; forced nudity; behavioural conditioning (e.g., being forced to dress or walk in a particular way); isolation (sometimes for long periods of time, which may include solitary confinement or being kept from interacting with the outside world); verbal abuse; humiliation; hypnosis; hospital confinement; beatings; and "corrective" rape. Conversion therapy appears to be performed widely by health professionals, including medical doctors, psychiatrists, psychologists, sexologists, and therapists. It is also conducted by spiritual leaders, religious practitioners, traditional healers, and community or family members. Conversion therapy is undertaken both in contexts under state control, e.g., hospitals, schools, and juvenile detention facilities, as well as in private settings like homes, religious institutions, or youth camps and retreats. In some countries, conversion therapy is imposed by the order or instructions of public officials, judges, or the police. The practice is undertaken with both adults and minors who may be lesbian, gay, bisexual, trans, or gender diverse. Parents are also known to send their children back to their country of origin to receive it. The practice supports the belief that non-heterosexual orientations are deviations from the norm, reflecting a disease, disorder, or sin. The practitioner conveys the message that heterosexuality is the normal and healthy sexual orientation and gender identity. The purpose of this medico-legal statement is to provide legal experts, adjudicators, health care professionals, and policy makers, among others, with an understanding of: 1) the lack of medical and scientific validity of conversion therapy; 2) the likely physical and psychological consequences of undergoing conversion therapy; and 3) whether, based on these effects, conversion therapy constitutes cruel, inhuman, or degrading treatment or torture when individuals are subjected to it forcibly2 or without their consent. This medico-legal statement also addresses the responsibility of states in regulating this practice, the ethical implications of offering or performing it, and the role that health professionals and medical and mental health organisations should play with regards to this practice. Definitions of conversion therapy vary. Some include any attempt to change, suppress, or divert an individual's sexual orientation, gender identity, or gender expression. This medico-legal statement only addresses those practices that practitioners believe can effect a genuine change in an individual's sexual orientation or gender identity. Acts of physical and psychological violence or discrimination that aim solely to inflict pain and suffering or punish individuals due to their sexual orientation or gender identity, are not addressed, but are wholly condemned. This medico-legal statement follows along the lines of our previous publications on Anal Examinations in Cases of Alleged Homosexuality1 and on Forced Virginity Testing.2 In those statements, we opposed attempts to minimise the severity of physical and psychological pain and suffering caused by these examinations by qualifying them as medical in nature. There is no medical justification for inflicting on individuals torture or other cruel, inhuman, or degrading treatment or punishment. In addition, these statements reaffirmed that health professionals should take no role in attempting to control sexuality and knowingly or unknowingly supporting state-sponsored policing and punishing of individuals based on their sexual orientation or gender identity.

Abstract
The use of telepathology for clinical applications in Canada has steadily become more attractive over the last 10 years, driven largely by its potential to provide rapid pathology consulting services throughout the country regardless of the location of a particular institution. Based on this trend, the president of the Canadian Association of Pathologists asked a working group consisting of pathologists, technologists, and healthcare administrators from across Canada to oversee the development of guidelines to provide Canadian pathologists with basic information on how to implement and use this technology. The guidelines were systematically developed, based on available medical literature and the clinical experience of early adopters of telepathology in Canada. While there are many different modalities and applications of telepathology, this document focuses specifically on whole-slide imaging as applied to intraoperative pathology consultation (frozen section), primary diagnosis, expert or second opinions and quality assurance activities. Applications such as hematopathology, microbiology, tumour boards, education, research and technical and/or standard-related issues are not covered.

Abstract
Background: The aim of the Eastern Québec telepathology project is to provide uniform diagnostic telepathology services across a huge geographic region with a low population density. This project is intended to provide surgeons and pathologists with frozen section and second opinion services anywhere and at any time across the entire region in order to avoid unnecessary patient transfer. Methods: The project has been implemented in 21 sites, each equipped with a whole slide scanner, a macroscopy station, two videoconferencing devices and a viewer/case management and collaboration solution. Of the 21 sites, 6 are devoid of a pathology laboratory. Of the remaining 15 sites, two have no pathologists, 6 have one and 7 have two or more. Results: The project has been successful and most appreciated by pathologists and surgeons. We report a number of challenges related to change management that we had to take into account in the course of implementation of this network. The challenges underscore the need for regular visits and active support to participating centers by the project team. Conclusion: The Eastern Québec telepathology network is successful and improves medical care in this region. In the course of implementation, we encountered a number of challenges which required innovative solutions.

Abstract
Certificates are acts meant to note facts of medical order. They constitute the proof of the bodily damage in a file of repair request. Only a doctor in medicine can write such a paper. The disciplinary, penal and civilian responsibility is committed every time that the doctor agrees to write a medical certificate. The medical secret must be respected when writing such a medical certificate. The document must be handed the patient. The dentist can establish certificates of different nature when he is asked by his patients, since the noted facts are part of his expertise. The certificate must be written after exam of the patient. The description of the lesions must be precise and complete. Under pain of nothing, the medical certificate must include: the identity of the doctor, the patient's one, the date of writing and the signature of the editor. The ITT show on the medical certificate is of great importance because it determines jurisdictions related to voluntary and involuntary violence.

Abstract
The authors report a case of malignant melanoma of the cervix uteri diagnosed in a young 35-year-old patient. Isolated genital bleeding was the beginning symptom. The physical exam showed a cervical dark tumor, with extension into the vagina (superior third), the parametrium was free. Cervical biopsy concluded to a malignant melanoma. No other abnormalities were observed and the tumor was classed stage IIA-FIGO. A total hysterectomy with bilateral annexectomy and pelvic lymphadenectomy was performed. In the way, the patient died after ten months by local and general recurrence. Primitive malignant melanoma of the cervix uteri is rare. Only 39 cases are reported in literature at this day. It is usually initially misdiagnosed mainly in the achromic forms, then the immuno-histochemical study is useful. Its treatment is not well codified and its histogenesis was controversial for a long time.

Abstract
For the last decade, numerous studies have focused on the positive or toxic effects of nitric oxide (NO) in procaryotic and eucaryotic cells. This gas has fundamental roles in neurotransmission, vasodilatation, cytotoxicity, and intestinal motility. The ability to produce NO by intestinal microflora or probiotic bacteria is unknown. In this preliminary study, we present a rapid and reproducible procedure for NO quantification and 15NO/14NO determination (based on the reaction between nitrite and acidic potassium iodide) by isotope ratio mass spectrometry. Using this method, we have demonstrated for the first time in vitro production of NO by a dietary bacterium (Propionibacterium acidipropionici, Pa 1) under anaerobic culture conditions. Using different sources of nitrogen, we have clearly shown that propionibacteria can synthesize NO from reduction of nitrate or nitrite. In our experimental conditions, NO synthase was not involved in NO production by propionibacteria.

Abstract
The authors report a case of a 47-years-old patient with Von Recklinghausen's disease. He was admitted with pericardial tamponade. 2D echocardiography showed, in addition to the compressive pericardial effusion, an enormous intrapericardial tumor compressing the left cardiac cavities. The patient died soon after pericardial drainage. The post-mortem examination revealed the diagnosis of malignant schwannoma of the left costo-vertebral gutter with an anterior intrapericardial development. A review of the literature showed that malignant schwannomas are seldom localized in the mediastinum, are associated with Von Recklinghausen's disease in 2 to 13% of cases, and have a poor prognosis. Pericardial tamponade is an exceptional presenting sign of mediastinal malignant schwannoma.
