Towards a predictive design regarding protection against the potential risk of COVID-19 an infection.
Background γδ T cells are an important subset of T lymphocytes that play important roles in innate and adaptive immunity via the secretion of various cytokines. Previous studies have found that long noncoding RNAs (lncRNAs) are critical regulators that contribute to the development of immune cells. However, the functions of lncRNAs in the γδ T cells remains poorly studied. Results Here, we identified the novel function of lncRNA NONHSAT196558.1 in isopentenyl pyrophosphate (IPP)-activated and -expanded γδ T cells using RNA-seq. As it functioned as an activating noncoding RNA of tumor necrosis factor related apoptosis-inducing ligand (TRAIL), an important cytotoxic cytokine that expressed by γδ T cells in responding to various infectious agents, we named this lncRNA as TANCR. Secondly, the expression of TANCR was found to be positively correlated with TRAIL expression in IPP activated γδ T cells. In addition, TANCR was confirmed to localized both in nucleus and cytoplasm. Finally, a loss-of-function was conducted by using siRNA/ASO or CRISPR/Cas9 system to knockdown or knockout TANCR, and confirmed that silencing of TANCR inhibits TRAIL expression in several kinds of cells, including HEK293T cells, Jurkat cells, and primary γδ T cells. Conclusion These evidences demonstrate that TANCR play important roles in γδ T cell activation. Furthermore, TANCR may be involved in the cytotoxicity of γδ T cells. This study aims to further our understanding of the molecular mechanisms underlying lncRNA-mediated immune responses. © The Author(s) 2020.MicroRNAs or miRNAs are a component of the non-coding RNAs family which is engaged in many cellular functions such as cell proliferation, apoptosis, gene expression, signaling pathways, angiogenesis, and etc. Endometriosis is a malignant gynecologic disorder occurring in women before menopausal age. Pathogenesis of this illness is still a discussion subject between the scientists but in our knowledge, microRNAs can be one of the possible involved factors. The purpose of this paper is to investigate the role of apoptotic activities of miRNAs in endometriosis. check details has demonstrated the role of cell proliferation, apoptosis, and invasion in the progression of these diseases. In this review, we looked into the specific role of apoptosis and its related genes and pathways in endometriosis and tied to present an explanation of how miRNAs can affect endometriosis by their apoptotic activities. What we found is that a great extent of miRNAs is involved in this illness and they are responsible for repressing apoptosis and progression of the disease. As a result, miRNAs have two different usages in endometriosis biomarkers and potential therapeutic targets. In this review we gathered a great amount of evidence to inquire into the role of micro RNAs in inducing apoptosis and how this mechanism can be exerted for therapeutic purposes for endometriosis. © The Author(s) 2020.Breast necrotizing fasciitis is a rare condition that has a tendency to rapidly progress with untoward morbidity and potential mortality. Its rarity often results to misdiagnosis and the fulminant course of the disease. We wish to present a case managed with nipple areola conservation following early intervention. We report a 28-year-old woman managed for unilateral right breast necrotizing fasciitis following stillbirth and resultant breast congestion in a background hypoalbuminemia. Early intervention ensured nipple-areola salvage. Wound was covered with split-thickness skin grafting. Early aggressive intervention in necrotizing fasciitis of the breast in a post-stillbirth lady with congestion contributed to preservation of nipple areola complex with eventual satisfactory management using split-thickness skin grafting.

The patient had an injury to his left medial malleolus 2 weeks prior, which failed outpatient care. During the physical exam, a soft mobile mass was palpated in the right popliteal fossa along with bilateral varicose veins, +1 pitting edema in bilateral lower extremities up to mid-calf. Duplex ultrasound revealed a saccular dilation in the right popliteal vein measuring 2.2 × 1.8 × 2.8 cm, without any evidence of superficial or deep vein thrombosis. #link# After an extended conversation with the patient and his care team, a decision to continue with medical management with close monitoring was made. Follow-up ultrasounds performed at 1, 6 and 12 months show no changes. Published by Oxford University Press and JSCR Publishing Ltd.

Many different terms refer to wandering spleen like dislocated spleen, ectopic spleen and displaced spleen. We report in this case a 13-year-old Syrian girl presented to the emergency department complaining of acute generalized abdominal pain with fever, anorexia and vomiting started 2 days prior to presentation. A splenectomy was performed, with uneventful postsurgical follow-up. Wandering spleen is prone to torsion and infarction resulting in acute abdomen and a life-threatening condition with high mortality rate reaching 50%. We advise the investigation of any recurrent episodes of chronic pain keeping up within mind this diagnosis. Published by Oxford University Press and JSCR Publishing Ltd.

This is an unusual presentation of a male patient with a history of laryngectomy who has had over a period of several years inappropriately and vigorously used valve cleaning brushes to clean tracheal secretions, which has led to the formation of a TOF. Due to the patient's obsessive habit, we could not manage him using conventional surgical methods. Instead, we opted for the placement of a salivary bypass tube, which yielded good results and recovery. To the best of our knowledge, no other case of similar aetiology has been published. We would like to highlight the importance of appropriate patient selection and education prior to performing a tracheoesophageal puncture to avoid developing life-threatening complications as demonstrated in our case report.
