A low-temperature plasma-based post-synthetic modification method was developed to directly introduce the hydroxy group into UiO-66 metal-organic frameworks (MOFs). UiO-66 can be endowed with greatly enhanced fluorescence properties after plasma treatment, with which a reliable sensing platform for arsenic has been established.One of the major limitations of current cancer therapy is the inability to destroy tumors with high efficacy and minimal invasiveness. Herein, we developed a proof-of-concept fixed-point "blasting" strategy to destroy the "castle" of tumors and realized efficient interventional photothermal therapy. The "blasting" materials were composed of photothermal nanoparticles (ancient ink nanoparticles, AINP) and a low boiling point phase change agent (perfluoromethylcyclopentane, FMCP). An injectable in situ-forming thermal-responsive hydrogel composed of biodegradable and biocompatible polymers was employed as a carrier to load the AINP and FMCP. The obtained hydrogel system was a flowable aqueous solution at low or room temperature for facile injection; meanwhile, once administered, it rapidly transformed into a fixed gel at a body temperature of about 37 °C. This unique property could effectually fix the AINP and FMCP and thus restrict the destruction region inside the tumor. Subsequently, triggered by second window near-infrared light, the solid tumors were effectively destroyed by a mild photothermal effect and the subsequent gas mechanical damage. We envisage that this fixed-point "blasting" strategy will pave a new way for the next generation of cancer-interventional photothermal therapy.We report on a supramolecular sensor array using fluorogenic peptide probes and graphene oxide that can target glycoproteins on a viral caspid, facilitating the differentiation of ebola virus from marburg virus and receptor-extensive vesicular stomatitis virus using principal component analysis.The electrochemical reduction of CO2 is a promising route for converting intermittent renewable energy into storable fuels and useful chemical products. A theoretical investigation of the reaction mechanism and kinetics is beneficial for understanding the electrocatalytic activity and selectivity. In this report, a kinetic model based on Marcus theory is developed to compute the potential-dependent reaction barrier of the elementary concerted proton-electron transfer steps of electrochemical CO2 reduction reactions, different from the previous hydrogen atom transfer model. It is found that the onset potentials and rate-determining steps for CO and CH4 formation are determined by the first and third concerted proton-electron transfer steps C1 and C3. The influence of binding energy, electrode potential, and reorganization energy on the computed reaction barriers of the C1 and C3 reactions is discussed. In general, the calculated reaction barrier shows a quadratic relationship with the applied electrode potential. Specifically, the reaction barrier is merely determined by the reorganization energy at equilibrium potential. The present kinetic model is applied to compare the electrocatalytic activities in the electrochemical reduction of CO2 on various copper crystal surfaces. Among the four studied copper single-crystal surfaces, Cu(211) exhibits the best electrocatalytic activity for CO formation and CH4 formation due to its low onset potential and overpotential.Langerhan's cell histiocytosis is an uncontrolled proliferation of dendritic cells. The involvement of skull base is rare. Variable clinical presentation and multi organ involvement often warrant a multidisciplinary approach for a successful diagnosis. We are reporting a case of 16-year-old male with sphenoid sinus Langerhan's cell histiocytosis which presented as a sudden and painless loss of vision. It is a rare entity in the diagnosis of blindness. Delayed diagnosis and treatment can result in serious complications. The radiological features and management options are discussed with a review of the pertinent literature. Keywords blindness; histiocytosis; langerhans-cell; sphenoid sinus.Fat embolism is a life-threatening condition that mostly occurs after long bones and pelvis fractures and treatment is controversial with many available drugs. We hereby present a case of 53 years male who developed shortness of breath, tachycardia, fever, anemia, distended jugular vein, thrombocytopenia, hypoalbuminemia and was diagnosed to have fat embolism after fracture of femur, tibia, fibula and pubic rami following road traffic accident. Patient was treated with 20 percent human albumin, N-acetylcysteine, other supportive treatment and discharged after fourteen days. From this we want to emphasize role of human albumin and N-acetylcysteine in treatment of fat. Keywords fat embolism; human albumin; N-Acetylcysteine.Lupus vulgaris is the commonest form of cutaneous tuberculosis. It is a chronic and slowly progressive disease. It can be transmitted either through hematogenous or lymphatic spread but most commonly through contiguous extension.There are many reports on different form of lupus vulgaris but there are only a few reports on large sized lupus vulgaris. Here, we report a case of 75-year-old man with a giant lupus vulgaris rapidly progressing in just two year's duration. Keywords cutaneous tuberculosis;lupus vulgaris; Nepal.Iatrogenic complications due to renal biopsy majorly include formation of an arterio-venous fistula, pseudoaneurysm or arterio-ureteral fistula. These complications are observed within a span of few days post biopsy and are rare after few years. We reported a case of 32-year-old renal allograft recipient male presenting 6 years post biopsy of the left kidney with left lumbar region pain who was eventually diagnosed with arterio-venous fistula and pseudoaneurysm involving inferior interlobular branch of left renal artery. Superselective embolization was achieved using coils and high concentration glue and transient placement of a venous occlusion balloon with complete technical and clinical success. Keywords renal arterio-venous fistula; renal biopsy; renal pseudoaneurysm.Postoperative visual loss is a rare but devastating complication of non-ophthalmic surgery. Its aetiology is poorly understood and multiple associated factors have been proposed. We present a report of a 33-year-old female who developed irreversible diminution of vision on the right eye (non-arteritic-posterior-ischemic-optic-neuropathy) following general anaesthesia for pedicle screw fixation and plating for fracture vertebrae and hip in prone position and then screw placement for fracture calcaneum in supine position. The vision loss, limited to finger count close to face on the right eye, did not improve till follow-up at one-year. The combination of mild intraoperative hypotension, anaemia, prone positioning, prolonged surgery and anaesthesia may have contributed to postoperative visual loss in our patient. Keywords ischaemic optic neuropathy; postoperative visual loss; spine surgery.Bronchospasm represents the clinical manifestation of bronchial muscles contraction resulting in reduced alveolar air flow. Non-allergic mechanisms or anaphylaxis underlie the genesis of perioperative bronchospasm, a potential anaesthetic disaster. Early recognition and treatment are crucial. We report a rare incident of anaphylactic bronchospasm without hypotension during general anaesthesia. Urticaria appeared in chest and abdomen suggesting anaphylaxis. After the event resolved with bronchodilators, surgery continued uneventfully. Vecuronium was the most probable culprit but confirmation was not possible as the patient was lost to follow up. Rarely, perioperative anaphylaxis presents only with bronchospasm that requires prompt attention to avoid adverse outcome. Keywords allergy; anaphylaxis; bronchial spasm; general anesthesia.Perinatal asphyxia is one of the major causes of neonatal morbidity and mortality. It mainly causes neurodevelopmental delay leading to hypoxic-ischemic encephalopathy. We present here the case of a preterm male baby of 1670 grams born at 31+3 weeks of gestation delivered by 25-year-old primi mother through vaginal delivery with history of umbilical cord prolapse. At birth, the baby had no heart rate and cyanosed following which he was resuscitated according to the Neonatal Advanced Life Support 2015 guidelines protocol. After 5 minutes of neonatal resuscitation, the baby's heart rate reappeared, but was only upto 20 beats/min and resuscitation thus continued. But heart rate did not improve despite of using all form of resuscitation procedure including intubation and drugs. After 2 hours, baby cried spontaneously and later baby was managed in Neonatal Intensive Care Unit according to the neonatal unit protocol of the hospital. Keywords birth asphyxia; cord prolapse; hypoxic ischemic encephalopathy.INTRODUCTION Hypertension is a cardiovascular disorder rapidly emerging as a major health problem in developing countries. Uncontrolled or poorly managed hypertension leads to several complications such as coronary heart disease, peripheral vascular disease and kidney disease. These complications account for approx 9.4 million deaths worldwide every year. Consequently, it is an urgent need for authorities to act upon this issue. This study was done to determine the prevalence of Hypertension in Deurali village of Nuwakot. METHODS A descriptive cross-sectional study was done in the Deurali Village of Nuwakot district from May 2019 to July 2019. Ethical approval was taken from the Ethical Review Board of Nepal Health Research Council. A simple random sampling method was applied. Blood pressure was measured on three occasions along with the use of a self-administered questionnaire. Descriptive statistical analysis was done. RESULTS The study showed the prevalence of hypertension among the adult population to be 20 (8.5%) [8.5%±1.83% at 95% CI]. Prevalence was found to be higher among female than male. Age group more than 60 were major sufferers of the condition. The study population consisted of the majority of Tamang community. Almost 213 (91%) participants were reported to have taken alcohol at some point in their life whereas only 104 (45%) were smokers.

Nepal is no exception. In the recent years, cancer care has seen a focus shift towards holistic healing. This includes screening and assessing for psychosocial distress, allowing health care providers to deliver timely psychological interventions. The goal of this study was to find the prevalence of psychosocial and functional impact of cancer diagnoses in Nepal. METHODS A descriptive cross-sectional study was carried out on 169 cancer patients attending out-patient department, day-care and in-patient department at B.P. Koirala Memorial Cancer Hospital, Nepal. National Comprehensive Cancer Network Distress Thermometer was used to evaluate spiritual/religious concerns, practical, family, emotional and physical issues and the distress score of these patients. RESULTS One-hundred and thirty eight (81.7%) of respondents had a Distress Thermometer score of ≥4. Distress Thermometer score of 7 was reported by the largest number of patients. Highest average Distress Thermometer scores were found in patients with hepatobiliary, head & neck and lung cancers.
