We analyze optomechanically induced Transparency and asymmetric Fano-line shape Profile in a two-mode cavity system, coupling at weak and strong coupling regimes. The model system consists of one mechanical mode and two optical modes. The transmission shows nonreciprocal behavior. Both the forward transmission and backward reflection for the system are analyzed for both optic-optic and mechanical-optic cavities by considering various system parameters. The output spectra lead to sharp asymmetric Fano-resonance and tunable transparency. Double line-shape profile is observed in the output Spectrum. Our proposal provides a new platform for application in quantum telecommunications and a photonic device like optical Switches.

Dear reader, isn’t it time to turn things around and allow TIME to take its rightful place? In a nutshell, I believe Time should be considered as the primary energy that has created the whole material world and governs the continuous changes in it. In my article “An Intelligent Cosmos: Philosophy of Science”, I discuss that this primary creative energy is, more generally, the Dark Energy in our Universe. I believe that Dark Energy probably has a variety of specific manifestations, and I assume that one of those manifestations is Time. This article is a continuation of my article “An Intelligent Cosmos: Philosophy of Science” 

Objective: In primary care, during treatments, nurses may need to wear surgical masks, namely for control of infection contamination, or to minimize unpleasant odors. The goal of this study is to inspect the effect of nurses wearing the mask on patient perception of the nurse-patient relation. Methods: A pre-post-test, control-experimental group design was employed with 60 patients treated in family health units. Patients responded to the Patient Satisfaction Questionnaire III (PSQ-III) regarding nurses’ communication, interpersonal manner, technical quality, as well regarding general satisfaction with the encounter. An additional question asked both patients and nurses how long they felt that the visit lasted. Results: Results show that nurses wearing the surgical mask had significantly negative effects in all dimensions of PSQ-III and increased the perceived visit duration among both nurses and patients. Conclusion: When a previous relationship exists, nurses wearing the surgical mask in primary care in Portugal negatively affects patient satisfaction with both the patient-nurse relation and the nurses’ technical quality. Practice implications: Is important the nurse understand this impact to discuss with the colleagues the best strategy to minimize the negative impact to the patient- family nurse relation and manager this situation in the best way to the patient. 

Broad-spectrum sunscreens are now widely used worldwide as an adjunct to help prevent sunburn, skin cancers and premature skin aging. In the United States, all persons older than 6 months are recommended to apply sunscreen to all sun-exposed skin from toes to head except eyes and mouth even on cloudy days. Such a recommendation is apparently based on concepts that exposure to sunlight damages the skin, the damage is cumulative and hence any sun exposure should be minimized or prevented. This communication raises several questions suggesting that the above recommendation may need to be reconsidered. For example, numerous previous studies have indicated many potential health benefits from non-burning sun exposure including protection against sunburn, melanoma, colorectal cancer, breast cancer and prostate cancer, increasing vitamin D synthesis, helping sleep, reducing blood pressure, heart attack and stroke. Recent studies suggested that regular lifetime non-burning sun exposure may not result in premature skin aging and the skin aging is mainly caused by the intrinsic factor. Skin aging or whole-body aging has been recently postulated to be mainly attributed to a gradual reduction in cardiac output/index with age and a new anti-aging or age-reversing nutritional theory has been proposed. An apparent lack of long-term cumulative sunray damage was also supported by reported age independence in incidences of sunburn and skin cancers. It is of interest that the current US policy is different from that of World Health Organization and Australia recommending the need of sun protection only when UV Index is 3 or greater. In view of the above, some general guidelines regarding when to best apply sunscreen are proposed.

Related COVID vaccine production many different strategies was followed by the producers. Observing some rare event of thrombosis after some COVID-19 vaccination, it is interesting to verify if the Target used for the manufacturing can be involved in a different procoagulant activity or not. Some vaccine are suspended in some country or under a deep new verify- investigation by the regulatory agency. (EU or USA). This fact it is relevant. The target SPIKE-PROTEIN FULL LENGTH modified or not or towards the RBD domain can be a relevant factor.

There are a lot of controversy about the usage of graft for reconstruction of the TMJ, many researchers tried in the past different technique to be applied in the TMJ [1], for restoration of growth and all failed and some of these techniques may be used for one trial without success.

Physician-patient communication is the most basic element and vital skill of physicians in the diagnosis, treatment, and establishing diagnostic protocols. As the risks of contagion and viral infection are higher in physicians and health workers, front line soldiers inpatient care units, so they should establish strict protective measures. However, patients value greatly face to face and close relationships with their doctors, including facial interviews and physical examinations. So social and physical distancing between physician and their patients can be remarked as a bigger toll than the risk of COVID-19 contagious.

The finite element method (FEM) is an engineering resource used to predict the stresses in structures that have complex geometries, specific material properties and are subject to complex loading patterns, being widely used in medical and biological research. It has the advantage of being a noninvasive and accurate method, which provides quantitative and detailed data about the physiological reactions that can occur in the tissues [1-5].

Introduction: Suicidal behavior in teenagers constitutes a health problem that, given the necessary measures of social isolation taken by the global emergency of the COVID-19 pandemic, must generate timely actions for its prevention and control from the public health services. Objective: To propose an action plan for the prevention of suicide in teenagers of the Remedios municipality, subjected to voluntary home confinement during the COVID-19 pandemic. Methods: an observational, descriptive, cross-sectional study was carried out in the “XXX Anniversary” Teaching Community Polyclinic of the municipality Remedios. We worked with the population of 25 teenagers between 12 and 19 years old who made suicide attempts in the period 2019-2021. The empirical methods used were: bibliographic and documentary review, participant observation, focus group, semi-structured interview and questionnaire. Results: The suicide attempt was common in female teenagers aged 17 to 19 years not identified as risk, the lack of motivation due to the study activity and the previous suicide attempts by ingesting psychotropic drugs without serious intention of dying predominated. The most frequent psychological disorders were emotional disorders, stress, depression, irritability, apathy and insomnia. Actions are presented for the prevention of suicide and promote behaviors that contribute to mental health in the context of COVID-19. Conclusion: The prevention of suicidal behavior in teenagers in conditions of social isolation due to COVID-19, must include actions that facilitate the coping with stress, intra-family communication and resilience.

Nanotechnology is a smart technology in the field of biomedical engineering used for the diagnosis and treatment of diseases. Nanodrugs provide better encapsulation of drug and efficiency at low dosage to kill the targeted tissue/cells. However, the chances of chronic toxicity and high cost of treatment limits its applicability [1]. To overcome these problems still, the experts of the scientific community have been working on it, to design the best one and cost-effective treatment for the human welfare.

“The mind of man is capable of anything….because everything in in it, all the past as well as all the future [Joseph Conrad]”. Why I am using above quote and what is the relation to what point I am coining you will understand its relevant your own as you moving line by line of this write-up. This topic though complex to some people to get understand, but those has strong or at least average background of Space, Physics, Quantum Mechanics, Neuroscience and theory of evolution definitely acquire it. Near distance and physical face to face communication started with the evolution of humankind and changes in each evolution in DNA structure caused to changes in communication patterns from different phonetics to gestures, gestures to voice and voice to voice with different languages.

In this study we describe a method for the detection of biomolecules (in the polypeptide m/z range) directly from the surface of plant leaves by using Mass Spectrometry Imaging. The plant-pathogen interaction between Arabidopsis thaliana and the bacterium Xanthomonas campestris pv. campestris was analyzed by comparing infected and non-infected leaf discs submitted to mass spectrometry. The total surface area of ion distribution was calculated for both samples, revealing 23 ions, out of which 3 showed statistical significance. Although these ions were not identified, the results showed that this approach can be successfully applied for the detection of potential polypeptide biomarkers directly on leaf tissue, which is a major challenge in MALDI-Imaging studies.

This very brief communication is aimed to highlight some recent contact points between neurosciences and dynamical system theory, passing through paleoneurology, with some remarks suggesting further possible interdisciplinary developments.

One of the major challenges for vaccine producing companies is having favourable conditions for efficient expression system for living organisms in order to produce biologicals. Several companies across the globe looking for several alternative sources for better yield through efficient expression based system.

Considering the geographical complexity and adversity, online communication and consultation are viable method in Nepal. The COVID-19 pandemic has accelerated the already starting trend of use of these technologies in medicine. In BPKIHS, telemedicine efforts were already initiated; lockdown rather warranted its maximum use. Here is an account of the observation made in telepsychiatry service provided by a consultant psychiatrist of its department of psychiatry. It is an institute-based observation noted for all the telepsychiatry consultations in 9 random duty days of the COVID-19 pandemic. Basic necessary information was noted down in a semi-structured proforma, like: socio-demographic, clinical information and advice provided. There were 104 subjects; 73 follow-up and 31 new: 60 male and 44 female cases. Clients of multi-ethnic groups were the most from urban, then semi-urban and least from rural areas. More consultations were for young age-groups and from nearby districts of Sunsari. Mood, somatic (sleep), anxiety were the top presenting complaints and 8/104 clients had suicidal symptoms. Maximum follow-up cases were improving. The most common diagnoses were: Mood (Depression and Bipolar), Anxiety, Psychosis and Substance use disorders. Most common treatment advices included: Antidepressants, Antipsychotics, Benzodiazepines and Counseling/psycho-education. Telepsychiatry is a viable method of delivering service even during the pandemic. 

In vitro fertilization is one of the most common and effective procedure for thousands of couples worldwide who want to have a child and are unable to do so for various reasons. Diverse studies show that couples who conceive naturally after one year of trying had newborns with an increased risk of prematurity and low birth weight, compared with couples who conceived before completing one year of trying. Children from assisted reproduction (AR), have a 30% increased risk of prematurity and low birth weight, compared with children from infertile fathers. Regarding the conflicting results the present study aimed to record the frequency of genetic, congenital anomalies in children and adolescents who had examined in the last decade to the Clinical Genetics Clinic of the National and Kapodistrian University of Athens whose mothers had undergone assisted reproduction. The research process was conducted at the "Aghia Sofia" Children's Hospital based in Athens. However, the cases that were studied came from all over Greece. Initially, the researcher recorded the cases that came to the clinic of Clinical Genetics and whose conception occurred after technical assisted reproduction. After telephone communication and the consent of the parents, a live appointment was scheduled. In this meeting-interview all the provisions of the investigation and the protocol were asked and some elements of the medical history of the cases were confirmed. The total sample included 230 children and adolescents. The resulting data were recorded on a printed form/questionnaire. Then, they were registered electronically in the program SPSS 25.0 (Statistical Package for Social Sciences) with a specific unit code for each case/patient, followed by the processing and statistical analysis of the data as well as the recording of the results. The gender of the participants was male for 118 participants (51.3%) and 112 females (48.7%). Mean and standard deviation (SD) of maternal, paternal (at the time of delivery) age was equal to 36.38 (5.94) and 39.94 (6.58) respectively. The observed abdormalities were 35.53% psychomotor retardation, 23.68% facial abnormalities, 23.68% spinal cord abnormalities, 21.05% morphological abnormalities, 20.61% short stature, 19.74% developmental disorders, 19.30% heart disease, 16.67% neurological diseases, 14.47% genetic syndromes, 11.40% genital abnormalities, 8.33% limb abnormalities, 7.46% dermatological abnormalities, 6.14% eye abnormalities, 6.14% hypothyroidism, 5.70% endocrine disorders, 5.26%otolaryngology abnormalities, 2.63% disease of kidney, intestine, 2.19% vascular malformations. Regarding the karyotype chromosome analysis by G-banding technique, from the 230 children in: 24 (10.43%) a pathological result was found, in 158 children (68.70%) it was found normal (46, XX or 46, XY by case) without other findings, while in 48 children (20.87%) the test was not performed for various reasons. Regarding the results of molecular analysis (DNA) from the 230 children, in 50 (21.74%) a pathological finding was found, in 56 children (24.35%) no abnormalities were found and in 124 children (53.91%) no molecular analysis was performed for various reasons. In conclusion, the sample of this descriptive study is characterized as uniform in terms of the method of assisted reproduction since 96.24% had followed the classic IVF. Full-term pregnancy was associated with the appearance of malignancy and head morphological abnormalities (64.6%), normal pregnancy was associated with genetic syndromes (18.2%) and facial abnormalities (11.1%). It is recommended the screening oocyte and sperm donors in order to help protect the safety and health of donors, recipients, and future offspring. The present study confirms the association of the presence of congenital anomalies after in vitro fertilization (IVF). However, the absolute risk of developing severe dysplasias after an IVF procedure is limited.

The SARS-Cov-2 virus was firstly identified in Wuhan, China and caused catastrophic destruction all over the world. COVID-19 virus primarily effects lungs of its hosts and impairs it in number of ways. It can also damage multiple organs like Heart, kidney, endocrine glands, skin, brain and several others. Kidneys are also damaged to a great extent. In Heart it can cause acute coronary syndrome, Heart failure, Myocardial infarction. SARS-CoV-2 effect brain especially psychologically. It also causes serious lymphocyte apoptosis. It also neutralizes human spleen and lymph nodes. SARS-CoC-2 can be harmful for those having already liver diseases. Similarly, SARS-CoV-2 has a direct impact on endocrine glands. It is responsible for the various injurious changes in hormones, causes various diseases like acute pancreatitis, decrease in GH, hypoparathyroidism etc. and lead to cause tissues damage in glands. It also some minor effects on nose, and respiratory pathways. It also has some minor effects on eyes and ears whereas it causes several devastations in GIT.

COVID-19 is a disease that is caused by SARS-CoV-2 and very speedily spreading all over the world. The blood group’s effect on COVID-19 is not clear. The main aim of this article is to determine the relationship between sensitivity of COVID-19 and ABO blood group. For this study we have observed that the individuals with blood group A are at higher risk of getting COVID-19 because they contain the higher concentration of Angiotensin-converting enzyme-2 that provide the site to virus for entry. But in other blood groups the natural Anti A antibodies block the interaction between host receptor and virus and disturb their interaction. Certain studies show that the infectivity and mortality rate in covid patients is not affected by AB blood group system. But according to research, increased ventilator usage, ICU stay was observed in critically ill patients with AB blood group than of other blood groups. O blood group has proved to be protective against SARS-CoV-2 due to the presence of both anti-A and anti-B antibodies as they prevent the binding of the spike protein S of the virus with the ACE2 receptors which are present on the surface of cells. Moreover, furin also plays a major role in penetration of virus in the host cells. Furin is required for the activation of the spike protein S of the virus and due to the low efficiency of furin cleavage in blood group O it is protected from SARS-CoV-2 and other chronic diseases. Mortality rate of covid 19 depends upon the environmental factors, number of people living in the area and also some economic factors. The different strains of COVID-19 effect the different people differently and as the time passes the strain of COVID-19 has changed and thus according to this the mortality rate of different provinces and areas varies due to environmental factors. Pregnant women have no any kind of transportation of covid to their fetuses but mostly patients of blood group A are being affected by COVID-19 and hence their fetuses are somehow effected. And those pregnant women having blood group O does not have any risk of COVID-19 of severe stages.

The main purpose of a High-intensity cultivation system is to maximize the yield crop per area unit through planting more trees, exploiting efficient use of different resources. There are different factors that affect high-intensity cultivation that include Land-cost, planting spaces, tree size, Rootstock, and Practice management. Meanwhile, the adoption of High-intensity cultivation to control canopy size, by using modern management practices is very crucial to get more yields in the early stages of the orchard besides simplicity in its management and increase the farmers’ net profit. In addition, High-density cultivation use in different fruit crops like olive, mango, orange, mandarin, Apple, and cherry. Numerous benefits of intensive fruit cultivation include increase fruit yield per unit area, improving use efficiency of natural resources e.g. soil, light, water, and nutrients, enhancing fruit quality, improving soil properties and rising levels of organic carbon and nutrients in plant tissues …etc. In addition, it is very effective in acid lime soil and achieves high income for the farmers.

Cutaneous metastases of urothelial tumors are extremely rare. Iatrogenic tumor implantations are the main cause of this type of metastasis. We report the case of a 75-year-old patient who underwent nephroureterectomy with the removal of a bladder collarette for a tumor of the upper excretory tract; 3 years later the patient developed parietal swelling at the level of the lumbotomy scar. A histological study of the mass after surgical excision confirmed that it was a secondary location. Through a study of the literature, we will detail the clinical and paraclinical particularities of such a location as well as its impact on the prognosis.
