SARS coronavirus 2 (SARS-CoV-2) in the viral spike (S) encoding a SARS-COV-2 SPIKE D614G mutation protein predominate over time in locales revealing the dynamic aspects of its key viral processes where it is found, implying that this change enhances viral transmission. In this paper, we strongly combine topology geometric methods targeting at the atomistic level the protein apparatus of the SARS-COV-2 virus that are simple in machine learning anti-viral characteristics, to propose computer-aided rational drug design strategies efficient in computing docking usage, and powerful enough to achieve very high accuracy levels for this in-silico effort for the generation of the AI-Quantum designed molecule of GisitorviffirnaTM, Roccustyrna_gs1_TM, and Roccustyrna_fr1_TM ligands targeting the COVID-19-SARS-COV-2 SPIKE D614G mutation using Chern-Simons Topology Euclidean Geometric in a Lindenbaum-Tarski generated QSAR automating modeling and Artificial Intelligence-Driven Predictive Neural Networks.

This paper studies the model of host pathogen with saturation and spatial heterogeneity. In the study of infectious diseases, the rate of saturation and spatial heterogeneity is an important factor affecting the spread of disease. First, since the solution semiflow of the model lacks of compactness, we prove the well-posedness of the model by verifying the smoothness of the semiflow. Then the basic reproduction number $R_0$ is determined, and its threshold effect is proved: when $R_0<1$, the system is globally asymptotically at the disease-free equilibrium; when $R_0>1$, we give the solution of the system that not only is uniformly persistent but also has a positive steady state. In addition, we analyze that the critical condition of $R_0=1$, that is, the global asymptotic stability of the disease free steady state remains true. The conclusions obtained in this paper can play a certain supporting role in the prevention and treatment of infectious diseases.

This paper is concerned with the well-posedness and long-time dynamics of a class of extensible beam equations with a semi-local nonlinear damping term given by $$-\gamma\mbox{div}\left[g(\nabla u_t)\right],\,\,(\gamma>0),$$ where $g\in C^1(\mathbb{R}^n,\mathbb{R}^n)$ is a gradient field of the form $g(s_1,\cdots,s_n)=(g_1(s_1),\cdots,g_n(s_n))$ with $g_i$ a monotone increasing function such that $g_i(0)=0$ and satisfies the growth condition $k|s|^{\alpha}\le g’_i(s)\le K(1+|s|^{\alpha})$ for all $s\in \mathbb{R}$, $i=1,\cdots,n$ and for some positive constants $k,K$ and $\alpha\ge 0$. This kind of damping arise in connection to the (fundamentally unbounded) nonlinearity proposed by Prestel in \cite{Prestel} in the context of wave equation. Our main results concern decay rates, existence of attractors and their properties.

The purpose of this paper is to develop the wave equation v_tt-v_xx=0 through the use of an optional function B(x) and some initial and boundary conditions, where the existence and uniqueness of the solution have been demonstrated by using the maximum and minimum principle, we give examples which show that the possibility of drawing.

We report the case of a 1-year-old male patient with systemic juvenile xanthogranuloma in whom central nervous system lesions caused developmental retardation, spasticity and clonus of the lower extremities. He needed tube feeding and experienced severe bronchitis and generalised convulsive seizure. KIF5B-ALK fusion was identified in the cutaneous lesion, and he was administered alectinib, an ALK inhibitor. Two months after the initiation of alectinib administration, the central nervous system lesions achieved partial regression. The spasticity and clonus were also relieved. A high index of cognition is needed for ALK fusion in infants with histiocytosis.

In this study, the nonlinear free vibration of a circular plate considering small scale effects has been investigated by using the nonlocal elasticity theory for a first time. To take into account the nonlinear geometric effects, the nonlinear model of von Karman strain has been used while the governing differential equation was extracted according to Hamilton principle. The Galerkin weighted residual method in conjunction with the variational iteration method (VIM) was introduced to solve the governing equations for simply supported and clamped edge boundary conditions. For further comparison, the nonlinear equation was solved using the fourth-order Runge-Kutta method. Very good agreements were observed between the results of both methods, while the former method made the solution much easier. Additionally, it was observed that the ratio of thickness to radius, h/R, plays an important role on the nonlinear frequencies. This effect appears to be minute if the local elasticity theory is adopted. However, results indicated that the nonlocal effect may be ignored provided h/R ratio is very small.

Graphene-based materials have demonstrated promising potential for adsorption and purification applications. Graphene oxide (GO), due to its amphiphilic nature, holds the possibility for removing various kinds of contaminants, including heavy metal ions and organic pollutants from aqueous environment. Here, we present size-selective ion adsorption in GO-based laminated membranes by directly measuring the weight uptake of slats. We tuned the interlayer spacing of GO membranes via cationic control solutions using intercalation of very small salts ions (i.e. K+, Na+, Cl-) very precisely to facilities the adsorption of larger ions such as [Fe (CN)6]4- and [Fe (CN)6]3-. This study demonstrates that if the opening of nanocapillaries within the laminates is bigger than the hydrated diameter of ions, the adsorption occurs within the membranes while for smaller opening, with no ion entrance the sorption is on the surface of the membranes.

In the context of the COVID-19 pandemic, we investigated the epidemiological and clinical characteristics in a young patient infected by avian influenza A (H5N6) virus in Anhui Province, East China, and analyzed genomic features of the pathogen. Through the cross-sectional investigation of external environment monitoring (December 29-December 31, 2020), 1 909 samples were collected from Fuyang City. It was found that the positive rate of H5N6 in Tianma poultry market was higher than other areas obviously, where the case appeared. The virus was the clade 2.3.4.4, which was most likely formed by genetic reassortment between H5N6 and H9N2 viruses. This study found that the evolution rates of HA gene and NA gene of the virus were higher than those of common seasonal influenza viruses. The virus was still highly pathogenic to poultry, and had a preference for avian receptor binding.

A 8 year-old female with sickle cell disease diagnosed at birth was confirmed to have neurofibromatosis type 1 at 13 months of age. At 7 years old, she was noted to have incidental papilledema with subsequent workup showing elevated opening pressure. She was diagnosed with intracranial hypertension and began treatment with acetazolamide and the discontinuation of hydroxyurea. Acetazolamide was tapered off and hydroxyurea was restarted with no worsening in her ophthalmologic exam. We report this case due to the rare occurrence of all three conditions as well as delineate the complications that can occur with the combination of diseases.

In early project stages often no simulation results are available for dividing wall columns. Hence, shortcut methods are helpful providing estimates for vapor and liquid splits which can be used for initializing rigorous process models. In a previous paper it was shown that diagrams are a suited tool to satisfy this need. However, it has turned out that the approach shows weaknesses for columns with finite and non-optimally allocated stage numbers. This contribution closes this gap and presents a new approach to derive suited initial guesses. For this purpose, the original diagram is combined with a heuristic approach to calculate Pareto-optimal column designs. The resulting stage-adapted diagram can then be used to graphically determine suited ranges of the vapor and liquid splits. A comparative study shows that the new approach is a powerful tool to enable reliable guesses for multiple dividing wall column simulations with finite stage numbers.

Biohydrogen production from biomass dark fermentation provides a great potential to achieve a green hydrogen economy. However, the purification of fermentative biohydrogen requires advanced separation technologies. This work focuses on the techno-economic feasibility analysis of H2-selective carbon membrane systems for biohydrogen enrichment by investigation of process operating parameters and membrane materials. High vacuum operation is favorable to reduce the specific cost. While the feed compression operation provides better separation performance, and the minimum specific cost of $ 0.026/Nm3 was identified to achieve the biohydrogen recovery of 90 % with a feed pressure of 6 bar. A two-stage carbon membrane system is technically feasible to reach the biohydrogen purity of >99.5 vol.% with the specific cost of $ 0.06/Nm3, which is lower than pressure swing adsorption. Compared to enhancing the membrane selectivity, improving hydrogen permeance by developing submicrometer asymmetric carbon membranes is urgently needed to increase its competitiveness for biohydrogen purification.

Aims: A commonly encountered problem in emergency care is pneumothorax, identified by air present in pleural space, occurring spontaneously, principally because of trauma or pathogenic factors like a central venous catheter, mechanical ventilation, and biopsy. Employing Chest ultrasound for diagnosing pneumothorax in an emergency is currently investigated by many researchers. The present meta-analysis aimed to assess Chest ultrasound’s diagnostic accuracy in diagnosing the pneumothorax during emergencies. Material and Methods: Literature search of published articles in MEDLINE, Embase, Ovid, Scopus, and Journal on web databases from 2000 up to November 2020 were reviewed for the pre-described outcomes. Results: 12 articles were finally chosen for quantitative analysis. The overall sensitivity of ultrasound scan in pneumothorax diagnosis was 89% (95 % CI – 86 – 91%). Specificity was 96% (CI – 95% – 97%). The diagnostic odds ratio was 193.94 (59.009 – 637.40) at 95% CI, thus demonstrating greater chest ultrasound accuracy in diagnosing pneumothorax. Conclusion: A definite evidence of chest ultrasound accuracy was noted in pneumothorax.

Some connection formulas are highlighted. Also the integral representation of those forms are given.

Background: Infective endocarditis (IE) is an infrequent intracardiac disease with high morbidity and mortality if treatment is not instituted opportunely Objective: To determine the echocardiographic characteristics related to postoperative adverse events (PAE) in patients with IE. Material and methods: Retrospective, single-center, observational cohort study in patients with IE undergoing surgical treatment between January 2018 and January 2020. 57 patients were included to evaluate the relationship between the echocardiographic characteristics and the development of post-surgical complications. Results: Average age 43 ± 14.6 years, 64.9% were male. 52.6% (n=30) presented PAE; Acute kidney injury being the most frequent 24.6%, heart failure 19.3%, major bleeding 19.3%, surgical reoperation 17.5%, arrhythmias 14%, septic shock 12.3%, mediastinitis 5.3%, and acute myocardial infarction 1.8%. The echocardiographic characteristics that were related to PAE were sPAP> 55% in 23.5%, p 0.004 and the presence of more than 2 vegetations with p 0.025, OR 1.84, 95% CI (1.03-3.28). Major bleeding was associated with the presence of 2 or more vegetations p 0.003, OR 9.23, 95% CI (1.27-66.81). Vegetation in both cardiac chambers were associated with heart failure p 0.008, OR 4.095, 95% CI (1.53-10.92) and septic shock p 0.001, OR 8.19, 95% CI (2.30-29.04). Mortality observed in the postoperative period was 21.1%. Conclusions: The location of vegetations in both cardiac chambers, the presence of 2 or more endocardial vegetations, as well as a sPAP> 55mmHg, are associated with a higher incidence of PAE in patients with IE.

Objective: To evaluate if SARS-CoV-2 is detectable in vaginal swabs and whether antibodies against SARS-CoV-2 are present in maternal and umbilical cord blood of pregnant women with COVID-19. Design: Prospective cohort study. Setting: Department of Obstetrics and Gynaecology, Copenhagen University Hospital – North Zealand, Denmark. Population: Pregnant women tested positive for SARS-CoV-2 in a pharyngeal swab between August 20th, 2020 and March 1st, 2021 who gave birth during the same period. Methods: Maternal blood sample and vaginal swabs were collected at inclusion. If included during pregnancy, these samples were repeated at delivery in addition to an umbilical cord blood sample. Swabs were analysed for SARS-CoV-2 and blood samples for SARS-CoV-2 total antibodies. Placental and neonatal swabs were performed on clinical indications. Main outcome measures: SARS-CoV-2 in vaginal swabs and SARS-CoV-2 total antibodies in maternal and umbilical cord blood. Results: We included 28 women, hereof 4 serious maternal or fetal outcomes including 1 neonatal death. Within the first eight days after a maternal positive pharyngeal swab, SARS-CoV-2 was detectable in two vaginal (2/28) and two placental swabs (2/4), whereas SARS-CoV-2 antibodies were detected in 1/13 women. After eight days, SARS-CoV-2 was not detectable in vaginal swabs and SARS-CoV-2 antibodies were observed in 19/21 of women. Antibodies in cord blood of seropositive mothers appeared after 16 days. Conclusion: Vertical transmission of SARS-CoV-2 seems plausible since SARS-CoV-2 is detectable in the vagina up to eight days after a positive pharyngeal swab at which time the neonate is not yet protected by antibodies.

Objective To identify risk factors for and outcomes after SARS-CoV-2 infection and severe COVID-19 in pregnancy Design Prospective population-based cohort study Setting Denmark Population All pregnancies between 1 March and 31 October 2020 Methods Using data from the Danish National Patient Register and Danish Microbiology Database and prospectively registered data from medical records, we compared women with a positive SARS-CoV-2 test during pregnancy to non-infected pregnant women. Severe infection was defined as hospital admission due to COVID-19. Main Outcome Measures Pregnancy, delivery, maternal, and neonatal outcomes. Results Among 82,682 pregnancies, 418 women had SARS-CoV-2 infection during pregnancy, corresponding to an incidence of 5.1 per 1000 pregnancies, 23 (5.5%) of which required hospital admission due to COVID-19. Risk factors for infection were asthma (OR 2.19 [1.41–3.41]) and being foreign born (OR 2.12 [1.70–2.64]). Risk factors for hospital admission due to COVID-19 included obesity (OR 2.74 [1.00–7.51]), smoking (OR 4.69 [1.58–13.90]), infection after gestational age in weeks (GA) 22 (GA 22–27: OR 3.77 [1.16–12.29]; GA 28–36: OR 4.76 [1.60–14.12]) and having asthma (OR 4.53 [1.39–14.79]). We found no difference in any obstetric or neonatal outcomes. Conclusions Severe outcomes of SARS-CoV-2 infection in pregnancy are rare.

Regional analgesia in Cardiac anesthesia: Welcoming a new era in perioperative pain management.Soojie Yu MD1, Oscar D. Aljure MD21 Mayo Clinic Arizona, Department of Anesthesiology2University of Miami, Department of Anesthesiology, Division of Cardiovascular and Thoracic AnesthesiologyPoorly controlled post-operative pain can delay recovery and may increase the risk of morbidity in patients undergoing cardiac surgery. After surgery, the sternal incision is the most common source of pain[1]. Historically, the mainstay for pain management in this population has been usage of narcotic analgesics but with the recognition that overprescription of opioids may be contributing to the opioid pandemic, an adoption of a multimodal approach for pain management has been gaining more popularity among institutions in the US. Neuraxial analgesia and anesthesia has been used in the past but its impact in hemodynamics added to the risk associated with heparinization and coagulopathy has limited its use in cardiac surgery[2]. Newer regional anesthesia/analgesia methods utilizing ultrasound guidance are associated with lower risk of complications when compared to neuraxial approach. Regional blocks that cover post-sternotomy pain include transverse thoracic muscle plane (TTMP) block, parasternal block, pecto-intercostal fascial blocks (PIFB), and erector spinae plane blocks[2]. Out of all these newer techniques, the number of published prospective double blinded studies are limited[2]. A contributing factor to the difficulty finding literature for these type of blocks is the description of the technique by the authors. A good example is the TTMP block where the local anesthetic is deposited in the TTMP block is similar to the described approach for the parasternal nerve block[3, 4]. Nomenclature aside, Kar and Ramachandran showed there are few prospective randomized control studies published on newer non-neuraxial regional techniques for postoperative pain control after cardiac surgery[2].In this issue of the Journal of Cardiac Surgery, Zhang et al present a prospective double-blinded study that looks at TTMP blocks placed pre-incision for post-sternotomy pain control after induction of anesthesia. In their study, for their TTMP block, the technique defined by the authors deposits local anesthetic between the costal cartilage and the transversus thoracis muscle as described similarly in other reports [5].Zhang and collaborators described on their study a significantly lower consumption of intraoperative opioids in the intervention group, that goes in hand with prior studies that have shown similar results when the block is performed after induction of anesthesia[6, 7]. In a study by Padala et al, patients who received blocks pre-incision had decreased fentanyl administration intraoperatively compare to patients who received the block prior to sternotomy closure[7]. In Zhang’s study, the block group had faster extubation times, decreased pain scores up to 24 hours after surgery and decreased post-operative opioid administration. The block group also had improved quality of sleep after extubation which can enhance recovery and decrease risk of delirium[8].While regional blocks are very effective as shown by Zhang et al, a common issue is the short duration of the analgesic effects. Studies based on patient satisfaction have shown that the majority of patients continue to have mild to moderate sternotomy pain especially with movement and coughing up to post-operative day three or later[9]. Whether the block was placed post-induction or prior to sternal closure, Padala’s study showed timing of placement of regional block did not seem to affect the total opioid requirement nor the pain scores for up to 24 hours postoperatively[7]. Another study by Lee and collaborators, evaluated if the administration of Liposomal Bupivacaine would prolong the analgesic effect of the regional block. This formulation of bupicaine can have analgesic effects up to 72 to 96 hours[10]. In the study, the parasternal intercostal block was placed just before sternotomy closure[10]. Overall pain scores up to 72 hours postoperatively were significantly lower when utilizing a linear mixed effects model at a 5% significance level in the Experal group compare to the placebo group[10]. Opioid administration though was not significantly different overall nor at individual time points up to 72 hours post-operatively[10].In this article, Zheng discusses the placement of a continuous infusion catheter as compared to a single shot block as an option to prolong the analgesic effects of the TTMP block. On a similar study, Ueshima, et al placed bilateral catheters after performing a TTMP block in two patients undergoing a median sternotomy. These catheters were administering intermittent and on demand boluses of levobupivacine for two days postoperatively. Both patients did not require any additional analgesics[11]. A limitation for this technique is that the catheters were placed after induction of general anesthesia and this could not be feasible in all cardiac surgeries with median sternotomy. The internal mammary artery (IMA) and vein courses through the TTMP therefore administration of local anesthetic or placement of a catheter could be an issue in patients undergoing coronary artery bypass grafting with IMA harvesting[6].TTMP blocks are relatively quick and easy to place but complications which include pneumothorax, local anesthetic allergy, infection [12] and injury to the internal mammary artery and vein can occur. One particular study showed tissue plane separation after the TTMP block that did not affect directly the ability to harvest the IMA nor did it have any obvious effect on the IMA[6]. In this study, Zheng had a very low incidence of complications adding to the safety profile of this block in cardiac surgery.Another popular technique that has been recently described that also targets the anterior intercostal nerves is the pecto-intercostal fascial block (PIFB) also called parasternal intercostal nerve block (PINB)[3]. For PIFB, local anesthetic is deposited between the pectoralis major and intercostal muscles making the location more superficial to TTMP block[13]. The more superficial location potentially decreases the risk of pneumothorax while still providing post-sternotomy pain control. Similar to TTMP blocks, patients who received PIFB had decreased pain scores but the amount of opioid consumption was not significant decreased compared to placebo control[13]. There has not yet been a study published comparing TTMP to PIFB for post-sternotomy pain control and risk of complications.In this issue of the Journal of Cardiac surgery, Zheng adds supporting evidence to the use of the newer non-neuraxial regional techniques as a feasible, practical option for the management of postoperative pain control in patients undergoing open cardiac surgery. This study adds to the growing evidence that TTMP blocks cover median sternotomy pain which is the main source of pain in post-cardiac surgery patients. The TTMP blocks are safe, easy to perform in the operating room after anesthesia and the incidence of complications is very low as reported in other studies. Limitations exist with TTMP blocks which include the relative short duration of analgesia. More studies will be needed to evaluate the continuous infusion of local anesthetic or other supplemental regional techniques to prolong the beneficial effects of this block.1.

Objective To examine race/ethnic and state variation in changes in US rates of labor inductions and rates of cesarean deliveries between 1990 and 2015, and to examine changes among a low-risk sample. Design Population-based, retrospective. Setting 50 states and D.C. Population All singleton first births in 1990 and 2015 from the National Vital Statistics System Birth Data. Separate analytic samples are created for births to Black (36 states, D.C.), Latina (42 states), and White women (50 states, D.C.). Methods Calculate joint probabilities of birth by weeks of gestation and by obstetric intervention status. Main Outcome Gestational age at birth is measured in weeks and obstetric intervention status was measured (1) vaginal delivery, no induction; (2) cesarean delivery, no induction; and (3) labor induction. Results The probability of birth between 37 and 39 weeks gestation increased substantially between 1990 and 2015 among births to U.S. Black, Latina, and White women. The increases were due to increases in labor induction at these weeks gestation and due to downward shifts in the gestational age timing of cesarean deliveries. Changes in the gestational age distribution did not differ by race/ethnicity, and similar changes in both gestational age and obstetric interventions were observed across U.S. states. The changes were also observed among U.S. women at low-risk for obstetric interventions. Conclusions Changes in gestational age distributions of U.S. births and their underlying causes are likely national-level phenomena and might not be responding to increases in maternal risk for interventions.

Introduction and aim Postoperative cognitive dysfunction is an important complication associated with increased morbidity, mortality, and reduced quality of life. Generally studies have focused on major surgery, while there is little evidence of the incidence of cognitive dysfunction in minor surgery. We aimed to compare general and spinal anesthesia in terms of cognitive decline in elderly patients after elective minor surgery using the Mini-mental state examination and Montreal cognitive assessment. Material and methods This observational study was conducted June 2014 to March 2015 at Ankara Numune Education and Research Hospital. The Mini-mental state examination and Montreal cognitive assessment scores were evaluated before and one day after the operation. Results The postoperative Mini-mental state examination scores of patients (26.23±2.77) were significantly lower than the preoperative scores (27.17±1.93) only in the general anesthesia group (p =0.003), while the postoperative Montreal cognitive assessment scores (22.87±3.88 for general and 23.13±4.08 for spinal anesthesia) were lower than the preoperative scores (24.32±3.19 for general and 24.35±2.84 for spinal anesthesia) in both the general and spinal anesthesia groups (p =0.000 and 0.019, respectively). The Postoperative cognitive dysfunction incidence was 32.9% using the Montreal cognitive assessment and was not significantly different between anesthesia methods. Conclusion Early Postoperative cognitive dysfunction is an important problem after elective minor surgeries, even with spinal anesthesia, in elderly patients. The Montreal cognitive assessment is an alternative tool that can be applied in a short time for screening cognitive functions in elderly patients. The cognitive screening of elderly patients perioperatively may be beneficial.

OBJECTİVES In our study, we aimed to compare the analgesic consumption, patient satisfaction rate, vital signs, and Visual Analogue Scale (VAS) scores of patients with and without ASA II, TAPblock, in cesarean surgery that takes general anesthesia, spinal anesthesia and epidural anesthesia. METHOD The files of 180 patients who underwent elementary cesarean section between January 2019 and December 2019 were analyzed retrospectively. ASA score, anesthesia method, age, weight, height, parity, TAP (Transvers abdominis plane) block application, VAS score, analgesia duration, additional analgesic requirement for hours, patient satisfaction, postoperative nausea, vomiting, urinary retention and other complications was recorded. 180 patients included in the study was divided in 6 groups: Group1 (n = 30): General anesthesia, Group 2 (n = 30): General anesthesia + TAP block, Group 3 (n = 30): Spinal anesthesia, Group 4 (n = 30): Spinal anesthesia + TAP block, Group 5 (n = 30): Epidural anesthesia, Group 6 (n = 30): Epidural anesthesia + TAP block. RESULTS There was no significant difference between the groups in terms of demographic variables. VAS scores of the first 24 hours were significantly different for Group 1. VAS scores in the 1st and 3rd hour were significantly higher in Group 1 than in other groups as well. The groups without TAP block were significantly higher than the VAS scores in the 12th hour. Further, Group 6 VAS score in 24th hour was significantly the lowest, and the earliest analgesic requirement was in Group 1. When the number of analgesic needs of the patients in 24 hour was examined, Group1 was found to be significantly the highest, and Group 6 was significantly the lowest of all groups. CONCLUSION The Epidural anesthesia + TAPblock group had the lowest VAS score, the fewest analgesic requirement, also the longest analgesia length, and the highest patient satisfaction.

Background: Recent reports have demonstrated the ability of mesenchymal stem cells (MSCs) to induce differentiation of neuroblastoma (NB) cells. Properties of dedifferentiated fat cells (DFAT) are similar to those of MSCs. In this study, we investigated if DFAT can induce NB cell differentiation and suppress cell proliferation. Procedure: DFAT was obtained from mature adipocytes isolated from adipose tissue from a ceiling culture. NB cells were cultured in a medium with or without DFAT. Subsequently, these cells were cultured in a DFAT-conditioned medium (CM) with or without phosphatidylinositol 3 kinase (PI3K) inhibitor. The neurites lengths were measured, and the mRNA expression levels of the neurofilament (NF) and tubulin beta III (TUBβ3) were assessed using quantitative real-time RT-PCR. Cell viability was assessed by the WST-1 assay.

4-Methylpyrazole (4MP) with the trade name Fomepizole is a derivative of pyrazole was studied by Density Functional Theory (DFT) with basis set 6-311++G(d,p). Using the B3LYP method and above basis set bond distance, bond angle and vibrational spectroscopy investigation was done. This method was used to get optimized structure, vibrational frequencies, and various other parameters. This work involves vibrational spectral analysis with the help of quantum mechanical computation. The computational results of IR were compared with reported experimental data, binding energies, elliptically and isosurface projection determined by Atom in molecule theory (AIM). The HOMO-LUMO mapping was reported which reveals the chemical activity in the molecule and the bandgap between HOMO to LUMO showed by the Frontier Molecular Orbital (FMO) energies. Chemically active sites of the molecule are obtained by Molecular electrostatic potential (MEP) and Fukui Function. UV-Visible spectra calculated with the help of the TDDFT/IEFPCM method using optimized parameters in different solvents obtained and compared with reported spectrum. NBO analysis showed the charge transfer between bonding and antibonding orbital. The like drug-likeness and molecular docking with 4 proteins were also done.

Locally advanced cholangiocarcinoma has a poor prognosis, with long-term survival observed only in patients where complete surgical resection is achieved. Pediatric cholangiocarcinoma is exceedingly rare, with an estimated 15-22 cases reported in the last 40 years. As such, no standard therapeutic regimen exists. Novel strategies combining conventional chemotherapy and radiotherapy followed by targeted agents can lead to durable treatment responses and are applicable to pediatric cholangiocarcinoma management. We present a case of a 17-year-old patient with unresectable cholangiocarcinoma whose tumor genetic sequencing revealed a novel, actionable NRG1 translocation, providing an opportunity to utilize combination treatment in the pediatric setting.

Inflammatory responses arise as an outcome of tissues or organs exposure towards harmful stimuli like injury, toxic chemicals or pathogenic microorganism. It is a complex cascade of immune mechanism to overcome from tissue injury and to initiate the healing process by recruiting various immune cells, chemical mediators such as the vasoactive peptides and amines, proinflammatory cytokines, eicosanoids and acute-phase proteins to prevent tissue damage and ultimately complete restoration of the tissue function. The cytokines plays a central role in communication between the cells, inflammatory response initiation, amplification and their regulation. This review will outline the importance of inflammatory responses, the role of cytokines in inflammation and various inflammatory disorders due to the abrupt expression of cytokines and also highlighted the hyper-inflammatory response or cytokine storm associated in the poor prognosis in COVID-19 pandemic.
