Boron-doped graphene topological defects: unveiling high sensitivity to NO molecule for gas sensing applications.

Global air quality has deteriorated significantly in recent years due to large emissions from the transformation industry and combustion vehicles. This issue requires the development of portable, highly sensitive, and selective gas sensors. Nanostructured materials, including defective graphene, have emerged as promising candidates for such applications.

Site specific interactions of amino acids with (ZnO) cluster: Density functional approach.

The Stability and electronic properties of bio-hybrid molecules are investigated in the framework of the first-principles density functional theory. The site-specific interactions between (ZnO) nano-cluster and arginine/aspartic acid are investigated. There are partially ionic and covalent bonds between the interacting atoms, higher binding energy 8.

ASXL1 mutations are associated with distinct epigenomic alterations that lead to sensitivity to venetoclax and azacytidine.

The BCL2-inhibitor, Venetoclax (VEN), has shown significant anti-leukemic efficacy in combination with the DNMT-inhibitor, Azacytidine (AZA). To explore the mechanisms underlying the selective sensitivity of mutant leukemia cells to VEN and AZA, we used cell-based isogenic models containing a common leukemia-associated mutation in the epigenetic regulator ASXL1. KBM5 cells with CRISPR/Cas9-mediated correction of the ASXL1 mutation showed reduced leukemic growth, increased myeloid differentiation, and decreased HOXA and BCL2 gene expression in vitro compared to uncorrected KBM5 cells.

Postoperative Analgesia After Panhysterectomy, Addition of Clonidine to Bupivacaine: Boon for the Patients.

Introduction: Postoperative period after panhysterectomy is very painful as there is too much tissue handling. In the practice of regional anesthesia neuraxial, opioids have been used extensively as an adjuvant to bupivacaine to enhance the potency and duration of sensory and motor block produced by bupivacaine with satisfactory results. However, delayed respiratory depression by opioids has prompted further research to develop nonopioid analgesics.

Comparison between Epidural Ropivacaine versus Ropivacaine with Clonidine in Patients Undergoing Abdominal Hysterectomy: A Randomized Study.

Context: Regional anesthesia has emerged as one of the preferred and convenient modes for intra- and post-operative management owing to its advantage of not interfering with the metabolic functions, better tolerability, and decrease in reflex activity. In recent years, ropivacaine has increasingly replaced bupivacaine as a preferred local anesthetic because of its similar analgesic properties, lesser motor blockade, and decreased propensity of cardiotoxicity. Neuraxial adjuvant such as clonidine used in epidural anesthesia offers advantage by augmenting the local anesthetic effect and reducing the anesthetic and analgesic requirement.

Relevance of Haematologic Parameters in Obese Women with or without Metabolic Syndrome.

Introduction: Obesity is rapidly growing problem worldwide. It predisposes to a variety of serious ailments including heart disease, diabetes mellitus, degenerative joint disease, atherosclerosis, etc. This is probably related to proinflammatory state associated with obesity due to release of several inflammatory mediators by the adipose tissue.

Aquaporin 5 regulates cigarette smoke induced emphysema by modulating barrier and immune properties of the epithelium.

Chronic obstructive pulmonary disease (COPD) causes significant morbidity and mortality. Cigarette smoke, the most common risk factor for COPD, induces airway and alveolar epithelial barrier permeability and initiates an innate immune response. Changes in abundance of aquaporin 5 (AQP5), a water channel, can affect epithelial permeability and immune response after cigarette smoke exposure.

Disparity in survival outcome after hematopoietic stem cell transplantation for hematologic malignancies according to area of primary residence.

We evaluated whether or not a patient's area of primary residence is an independent risk factor for overall survival (OS) after HLA-identical sibling or autologous hematopoietic stem cell transplantation (HSCT). This retrospective cohort study included patients who underwent autologous (n = 1739) or HLA-identical sibling (n = 267) HSCT to treat a hematologic malignancy between 1983 and 2004 at the University of Nebraska Medical Center. Primary area of residence, using the patient's zip code, was categorized as either urban or rural (including isolated, small rural, or large rural) according to the Rural Urban Commuting Area Codes (RUCA) classification system.

Germinoma-unusual presentation: a case report.

Germinoma accounts for two-thirds of germ cell tumors and about 40% of all pineal region neoplasms. This case illustrates an unusual manifestation of metatastic germinoma with spread to ventricles and meninges without a pineal mass. A 24-year-old man presented with nausea, vertigo, and left facial droop.
